More specifically, the abutting portion 26 (a hatched portion in FIG. 3A) that abuts against the partition plate 12 when the fixed-side plate-like member 20 is attached to the lower end (bottom) of the accommodating portion 2. The fixed-side fertilizer opening 23 exists on the center side of the fixed-side plate-like member 20 as a boundary, and the fixed-side agricultural chemical opening 25 exists on the outer peripheral side of the fixed-side plate-like member 20 with respect to the contact portion 26. The fixed-side fertilizer opening 23 and the fixed-side pesticide opening 25 are provided at positions adjacent to each other in the radial direction of the fixed-side plate-like member 20 via the contact portions 26.

  The fixed fertilizer opening 23 and the fixed pesticide opening 25 are each fan-shaped. The opening area of the fixed fertilizer opening 23 is larger than the opening area of the fixed pesticide opening 25. More specifically, the arc constituting the outer edge of the fixed-side fertilizer opening 23 is a part of a circle having radii r1 and r2 with the shaft insertion hole 22 as the center, and the opening angle thereof is θ1 (θ1 <180 degrees). Has been. Moreover, the circular arc which comprises the outer edge of the fixed side agricultural chemical opening 25 is a part of circle | round | yen of radius r3, r4 centering on the shaft penetration hole 22, The opening angle (theta) 2 is below the opening angle (theta) 1 of the stationary side fertilizer opening 23 (Θ1> θ2). Further, the difference (| r4-r3 |) between the radii r3 and r4 of the arcs constituting the fixed pesticide opening 25 is the difference (| r2-r1 |) between the radii r1 and r2 of the arcs constituting the fixed fertilizer opening 23. It is as follows. The size of the opening area of the fixed side fertilizer opening 23 and the fixed side pesticide opening 25 is appropriately adjusted in consideration of the mixing ability of the mixing unit 5 and the like. Moreover, the ratio of the opening area of the fixed-side fertilizer opening 23 and the fixed-side agricultural chemical opening 25 is appropriately adjusted according to the mixing ratio of the fertilizer and the agricultural chemical.

  The rotation side plate member 21 is disposed below the fixed side plate member 20 as shown in FIGS. There is almost no gap between the rotating side plate member 21 and the fixed side plate member 20. The rotation side plate member 21 is disposed substantially parallel to the fixed side plate member 20.

  The rotation side plate-like member 21 has a shaft insertion hole 30 at the center as shown in FIGS. 3B and 4, and a rotation side fertilizer opening 31 (first communication opening) and a rotation side agricultural chemical opening on the outer peripheral side thereof. 32 (second communication port). The rotation-side fertilizer opening 31 has substantially the same shape as the above-described fixed-side fertilizer opening 23, and the opening area is also substantially the same. More specifically, the arc constituting the outer edge of the rotation-side fertilizer opening 31 is an arc having radii r1 and r2 with the shaft insertion hole 30 as the center, and the opening angle is θ1 (θ1 <180 degrees). . The arc that forms the outer edge of the rotation side pesticide opening 32 is a part of a circle having radii r3 and r4 with the shaft insertion hole 30 as the center, and the opening angle θ2 is equal to or less than the opening angle θ1 of the rotation side fertilizer opening 31. (Θ1> θ2). Further, the difference (| r4-r3 |) between the radii r3 and r4 of the arcs constituting the rotation-side pesticide opening 32 is the difference (| r2-r1 |) between the radii r1 and r2 of the arcs constituting the rotation-side fertilizer opening 31. It is as follows.

  In the rotation side plate-like member 21, the positional relationship between the rotation-side fertilizer opening 31 and the rotation-side pesticide opening 32 is different from the positional relationship between the fixed-side fertilizer opening 23 and the fixed-side pesticide opening 25 of the fixed-side plate-like member 20. That is, assuming a virtual line L that passes through the center of the rotation-side plate member 21, the rotation-side fertilizer opening 31 is formed in one area with the virtual line L as a boundary, and the rotation-side pesticide opening 32 in the other area. Is formed. Further, as shown in FIG. 5A, the rotation-side fertilizer opening 31 overlaps the rotation-side plate-like member 21 and the fixed-side plate-like member 20 so that the fixed-side pesticide opening 25 and the rotation-side pesticide opening 32 communicate with each other. In this case, the fixed-side fertilizer opening 23 is provided at a position that is line-symmetric with respect to the virtual line L described above. In other words, the rotation-side fertilizer opening 31 is provided at a position shifted from the rotation-side pesticide opening 32 by about 180 degrees in the circumferential direction of the rotation-side plate member 21.

  The power transmission mechanism 35 includes an input shaft 36, a power conversion unit 37, and an output shaft 38. The input shaft 36 is a shaft connected to a power source such as a PTO (Power Take Off) shaft provided on a tiller or a tractor, a rotating shaft of a motor, or the like. The input shaft 36 is connected to the power conversion means 37. The power conversion unit 37 includes a gear (not shown) and the like, and decelerates the power input via the input shaft 36 and outputs it to the output shaft 38. As shown in FIGS. 2 and 4, the output shaft 38 is inserted into shaft insertion holes 22 and 30 provided in the fixed side plate member 20 and the rotation side plate member 21, and is fixed to the rotation side plate member 21. Yes. Therefore, the mixing ratio adjusting unit 3 rotates the output shaft 38 to rotate the rotation-side plate member 21 while maintaining a substantially parallel posture with respect to the fixed-side plate member 20, thereby fixing the fixed-side fertilizer of the fixed-side plate member 20. The opening 23 and the fixed pesticide opening 25 can be opened and closed.

  More specifically, the mixing ratio adjusting unit 3 causes the stationary side agricultural chemical opening 25 and the rotational side agricultural chemical opening 32 to communicate with each other by rotating the rotational plate member 21 as shown by hatching in FIG. be able to. That is, when the rotary side plate-like member 21 is adjusted to the position as shown in FIG. 5A, the fixed side agricultural chemical opening 25 is opened, and the agricultural chemical stored in the agricultural chemical storage section 11 can be dispensed. In this state, the fixed-side fertilizer opening 23 is closed by the rotation-side plate member 21. Therefore, in the state shown to Fig.5 (a), the fertilizer in the fertilizer accommodating part 10 cannot be paid out.

  Further, when the rotation-side plate member 21 is further rotated counterclockwise (in the direction of the arrow in FIG. 5A) by about 180 degrees from the state shown in FIG. 5A, as shown by hatching in FIG. 5B. The fixed-side fertilizer opening 23 and the rotation-side fertilizer opening 31 can be communicated with each other. That is, when the rotation-side plate-like member 21 is adjusted to a position as shown in FIG. 5B, the fixed-side fertilizer opening 23 is opened, and the pesticide in the pesticide container 11 can be dispensed downward. Further, in the state shown in FIG. 5B, the fixed side agricultural chemical opening 25 is closed by the rotation side plate-like member 21, and the agricultural chemical in the agricultural chemical accommodation unit 11 cannot be dispensed.

  Furthermore, when the rotation-side plate-like member 21 is rotated in a predetermined direction, the mixing ratio adjusting unit 3 is fixed as shown in FIG. 5 (a) with the fixed-side pesticide opening 25 opened and as shown in FIG. 5 (b). The state in which the side fertilizer opening 23 is opened is alternately switched. Therefore, the agricultural spraying apparatus 1 can alternately discharge the agricultural chemical and the fertilizer from the storage unit 2 to the mixing unit 5 side by rotating the rotation-side plate member 21 in a certain direction.

  The mixing unit 5 is provided below the mixing ratio adjusting unit 3 as shown in FIG. The mixing part 5 has a mixing chamber 40 (accommodating part) whose upper end side and lower end side are open, and a stirrer 45 is accommodated therein. The mixing chamber 40 is provided at a position such that the opening 41 provided at the upper end is directly below the fixed-side fertilizer opening 23 and the fixed-side agricultural chemical opening 25 of the mixing ratio adjusting unit 3. An opening 43 is provided at the lower end (bottom surface) of the mixing chamber 40.

  The stirrer 45 is constituted by a mixing device with a stirrer which is generally called a slab mixer. In the present embodiment, the stirring device 45 is configured such that a large number of gutter plates 46 (mixing members) are attached to a rotating shaft 50 (diffusion side rotating member, mixing side rotating member). The gutter plate 46 is attached in a spiral shape to the rotary shaft 50 erected substantially vertically. That is, the stirring device 45 has a rotation shaft 50 extending along the dropping direction of the fertilizer and agricultural chemical falling from the storage unit 2 side, and a plurality of gutters 46 are attached to the rotation shaft 50. Yes. A plurality of ribs 46 are attached at predetermined intervals in the circumferential direction and the axial direction of the rotating shaft 50. Therefore, when the stirrer 45 is operated, the slat 46 rotates so as to cross the fertilizer and the agricultural chemical falling from the container 2 to the mixing chamber 40, and the agricultural chemical is dispersed substantially uniformly with respect to the fertilizer. .

  The rotating shaft 50 is an output shaft of the power transmission mechanism 47 disposed below the spraying unit 6 described later. Similar to the power transmission mechanism 35 described above, the power transmission mechanism 47 includes an input shaft 48, power conversion means 49, and a rotation shaft 50. The input shaft 48 is a shaft connected to a power source such as a PTO (Power Take Off) shaft provided in a tiller or a tractor or a motor, and is connected to a power conversion means 49. The power conversion means 49 incorporates a gear or the like (not shown) in the same manner as the power conversion means 37 described above. The power transmission mechanism 47 is configured to decelerate the power input to the power conversion means 49 via the input shaft 48 and output it to the rotary shaft 50.

  As shown in FIG. 2, the spraying unit 6 is configured to accommodate a power transmission mechanism 47 and a rotating plate 51 in a spraying chamber 58 provided directly below the mixing chamber 40. It is set as the structure which can spray the mixture of a fertilizer and a pesticide from the spraying opening 56 provided in the surrounding wall. It is desirable that the width (opening angle θ5) of the spray opening 56 be large to improve the spray characteristics of the mixture. In the present embodiment, the opening angle θ5 of the spraying opening 56 is set to about 90 to 180 degrees.

  The spraying unit 6 shares the rotating shaft 50 of the stirring device 45 and the power transmission mechanism 47 described above, and has a configuration in which a rotating plate 51 is attached to the rotating shaft 50. The rotating plate 51 is attached substantially perpendicularly to the rotating shaft 50 and exists immediately below the opening 43 provided on the bottom surface of the mixing chamber 40.

  As shown in FIG. 6A, the rotating plate 51 includes a disc portion 52 configured by a disc having a substantially circular shape in plan view, and a spraying blade 53 that rises substantially perpendicular to the disc portion 52. The spreading blades 53 are provided so as to extend radially outward from the substantially central portion of the disc portion 52 in a plan view. A shaft insertion hole 55 is provided at a substantially central portion of the rotating plate 51. The rotating plate 51 is in a posture in which the spreading blade 53 faces the mixing unit 5 side, and is fixed to the rotating shaft 50 inserted through the shaft insertion hole 55.

  The rotating plate 51 is positioned and installed so that the mixture of fertilizer and agricultural chemical falls from the opening 43 of the mixing chamber 40 at a position away from the center. Therefore, when the rotating shaft 50 is operated and the rotating plate 51 is rotated, the mixture of the fertilizer and the agricultural chemical that has fallen on the rotating plate 51 is diffused toward the outside of the rotating plate 51 and is distributed almost uniformly. The mixture sprayed with the rotation of the rotating plate 51 is diffused and sprayed from the spraying opening 56 provided on the side of the spraying chamber 58 to the outside of the agricultural spraying apparatus 1.

  As described above, the agricultural spraying device 1 simply mixes fertilizer and pesticide in the fertilizer storage unit 10 and the pesticide storage unit 11, and mixes them in a predetermined ratio in the mixing unit 5. Can be supplied and sprayed. Therefore, according to the agricultural application | coating apparatus 1, fertilizer and agrochemical can be distributed at once, and the effort and time which a spraying operation requires can be suppressed to the minimum.

  In the agricultural spraying device 1 described above, when fertilizer and pesticide are supplied from the fertilizer storage unit 10 and the pesticide storage unit 11 to the mixing chamber 40 of the mixing unit 5, they are agitated by the mortar plate 46 attached to the rotary shaft 50. Possible configuration. Therefore, the agricultural spraying device 1 can supply the sprayer 6 as a state in which the agricultural chemical is substantially uniformly dispersed with respect to the fertilizer and spray it.

  As described above, the agricultural spraying device 1 of the present embodiment is configured to share the rotating shaft 50 between the mixing unit 5 and the spraying unit 6. Therefore, in the agricultural spraying apparatus 1, the mixing member of the mixing unit 5 and the rotating unit of the spraying unit 6 can be operated with a single power source. Therefore, the agricultural spraying device 1 has a simple device configuration.

  In the said embodiment, although the rotating shaft 50 was comprised by the single shaft body, this invention is not limited to this, For example, the site | part by the side of the mixing part 5 among the rotating shafts 50 and The site | part by the side of the spreading | diffusion part 6 is a different body, and these may be connected and integrated.

  Since the agricultural spraying apparatus 1 of the said embodiment shares the rotating shaft 50 with the mixing part 5 and the spraying part 6, the base plate 46 provided in the mixing part 5, and the rotation provided in the spraying part 6 The plate 50 rotates at the same rotation speed. Here, the rotating plate 50 provided in the spraying unit 6 may be required to rotate at a high speed in order to disperse the mixture of fertilizer and agrochemicals, but the plate 46 of the mixing unit 5 is very fast. It is assumed that there is no need to rotate. That is, the optimum value of the rotation speed of the cover plate 46 may be different from the optimum value of the rotation speed of the rotation plate 50. Therefore, in such a case, a transmission is provided between the mixing unit 5 and the spraying unit 6, and the rotary shaft 50 is used for the spraying unit 6, and the power of the rotary shaft 50 can be input to the above-described transmission. The output shaft of the transmission may be used as the rotating shaft for the mixing unit 5. In other words, a shaft corresponding to the rotation shaft 50 in the above embodiment may be prepared separately on the mixing unit 5 side and the spraying unit 6 side, and these may be connected via a transmission. With this configuration, the gutter plate 46 and the rotary plate 50 can be operated with a single power, and the respective rotation speeds can be adjusted independently.

  Here, in the agricultural spraying device 1 described above, when the opening 43 is provided in the substantially central portion of the bottom of the mixing unit 5, the mixture formed by mixing the fertilizer and the pesticide in the mixing unit 5 is formed in the spraying unit 6. There is a possibility that the mixture falls to the approximate center of the rotating plate 51 and the mixture is scattered to a portion where the spray opening 56 is not opened, resulting in a spray loss of the mixture. Therefore, in the present embodiment, an opening 43 is provided at a position off the center of the bottom of the mixing unit 5, and the mixture is dropped to a position away from the center of the rotating plate 51. Therefore, in the agricultural spraying apparatus 1 of the present embodiment, the mixture falling on the rotating plate 51 can be sprayed almost uniformly over a wide range without waste.

  In the present embodiment, an example in which the opening 43 is provided at a position where the mixture can drop to a position away from the center of the rotating plate 51 in consideration of the size of the opening angle θ5 of the spraying opening 56 is illustrated. However, the present invention is not limited to this, and an opening 43 may be provided substantially at the center of the bottom of the mixing unit 5 so that the mixture can drop at the center of the rotating plate 51 or in the vicinity thereof. In such a configuration, if the opening angle θ5 of the spraying opening 56 can be increased, the sprayable region of the mixture in the spraying unit 6 can be further expanded.

  In the said embodiment, although the example which provided the opening 43 in the position which can drop the mixture discharged | paid_out from the mixing part 5 to the position off the center of the rotating plate 51 provided in the spreading | diffusion part 6 was illustrated, The invention is not limited to this, and the opening 43 may be provided at an appropriate position such as the approximate center of the mixing portion 5, and a mixture guide means 65 such as a hopper may be provided below the opening 43. In the case of such a configuration, if the mixture guide means 65 can be supplied to a predetermined position of the rotating plate 51 of the sprinkling unit 6, the mixture that has fallen on the rotating plate 51 can be reduced over a wide range as in the present embodiment. Can be spread evenly.

  As described above, in the agricultural spraying apparatus 1 of the present embodiment, the mixing ratio adjustment unit 3 configured by combining the fixed side plate member 20 and the rotation side plate member 21 is provided, and the fertilizer and the pesticide are used. The opening areas of the fixed-side fertilizer opening 23, the fixed-side pesticide opening 25, the rotation-side fertilizer opening 31 and the rotation-side pesticide opening 32 are adjusted according to the mixing ratio. Therefore, the agricultural spraying apparatus 1 of the present embodiment can mix and spray them at a desired mixing ratio simply by putting the fertilizer and the agricultural chemical in the fertilizer storage unit 10 and the agricultural chemical storage unit 11.

  Moreover, in the above-mentioned agricultural spraying apparatus 1, when the mixing ratio adjustment part 3 rotates the rotation side plate-shaped member 21, the fixed side fertilizer opening 23 and the rotation side fertilizer opening 31 communicate, 25 and the state where the rotation side agricultural chemical opening 32 communicates alternately. Therefore, in the agricultural spraying apparatus 1, when the rotation-side plate member 21 is rotated in a certain direction, the fixed-side fertilizer opening 23 and the fixed-side pesticide opening 25 are opened every rotation cycle of the rotation-side plate member 21, and the first granular The product and the second granular material are alternately supplied to the mixing means. Therefore, in the agricultural spraying apparatus 1, a large amount of the first granular material and the second granular material are not discharged at a time to the mixing unit 5, and these are clogged in the opening 43 that functions as the discharge port of the mixing unit 5. Such a trouble is unlikely to occur.

  In the said embodiment, the mixing ratio adjustment part 3 is comprised combining the stationary-side plate-shaped member 20 and the rotation-side plate-shaped member 21, and only fertilizer and a pesticide are rotated by rotating the rotation-side plate-shaped member 21. Therefore, it can be paid out to the mixing unit 5. Therefore, in the agricultural spraying device 1, it is possible to prevent agricultural chemicals and fertilizer from being clogged in the opening 43 corresponding to the outlet of the mixing unit 5 or causing so-called bridging in the mixing unit 5.

  In the above embodiment, since the opening areas of the fixed-side fertilizer opening 23, the fixed-side pesticide opening 25, the rotation-side fertilizer opening 31, and the rotation-side pesticide opening 32 are constant, the amount of fertilizer and pesticide dispensed to the mixing unit 5 and these However, the present invention is not limited to this, and one or a plurality selected from the openings 23, 25, 31, and 32, or all the opening areas can be appropriately adjusted. Good. More specifically, for example, as shown in FIG. 9, a fixed-side fertilizer opening 23 provided on the fixed-side plate-like member 20 or a fixed-side is provided at a position such as between the fixed-side plate-like member 20 and the rotary-side plate-like member 21. The plate-shaped opening area adjusting means 80 having the openings 81 and 82 in the same positional relationship as the pesticide opening 25 may be configured to be able to operate independently with respect to the rotation-side plate-like member 21. In the case of such a configuration, the opening area adjusting means 80 and 85 are rotated relative to the fixed side plate member 20 as indicated by arrows in FIG. Can be adjusted. In the example shown in FIG. 9, the opening area adjusting means 80 has a disc shape, but the shape and the like are particularly suitable as long as the opening area of the fixed fertilizer opening 23 and the fixed pesticide opening 25 can be adjusted. For example, it may be a sector or rectangular shape.

  Alternatively, an opening area adjusting means for adjusting the opening area of the fixed-side fertilizer opening 23 and an opening area adjusting means for adjusting the opening area of the fixed-side agricultural chemical opening 25 may be provided so that each can be operated independently. In such a configuration, not only the amount of fertilizer and agricultural chemicals dispensed to the mixing unit 5 but also the ratio (mixing ratio) of these amounts dispensed can be adjusted.

  Further, an opening area adjusting plate in which openings having different opening areas from the openings 23 and 25 are provided at the same positions as the fixed fertilizer openings 23 and the fixed pesticide openings 25 provided in the fixed plate member 20 described above. It is good also as a structure which prepares a body and can replace this suitably according to the discharge amount and mixing ratio of a fertilizer or an agrochemical. Also in the case of such a configuration, the amount of fertilizer and agricultural chemicals dispensed to the mixing unit 5 and the fertilizer can be adjusted by appropriately adjusting the opening area of the openings provided corresponding to the openings 23 and 25 in the plate for adjusting the opening area. And mixing ratio of agricultural chemicals can be adjusted.

  In the said embodiment, the fixed side plate-shaped member 20 and the rotation side plate-shaped member 21 illustrated the structure in which the positional relationship of the fixed side fertilizer opening 23 and the rotation side fertilizer opening 31 which form a fertilizer exit is in a line symmetrical position relationship. However, the present invention is not limited to this, and the openings 23 and 31 may be configured so as to be somewhat displaced in the circumferential direction of the fixed side plate member 20 or the rotation side plate member 21.

  Further, in the mixing ratio adjustment unit 3, the positional relationship between the fixed-side fertilizer opening 23 and the rotation-side fertilizer opening 31 in the fixed-side plate-like member 20 and the rotation-side plate-like member 21 may be the same. That is, when the fixed-side plate-like member 20 and the rotary-side plate-like member 21 are overlapped, the mixing ratio adjusting unit 3 communicates with the fixed-side fertilizer opening 23 and the rotary-side fertilizer opening 31 and rotates with the fixed-side pesticide opening 25. The side pesticide opening 32 may be configured to communicate.

  In the said embodiment, although the thing of the structure which combined the stationary side plate-shaped member 20 and the rotation side plate-shaped member 21 was illustrated as the mixing ratio adjustment part 3, this invention is not limited to this, For example, a fertilizer accommodating part It is good also as a structure which puts a shutter etc. in the bottom part of each of 10 and the agrochemical storage part 11, and throws a predetermined quantity of fertilizer and agrochemicals into the mixing chamber 40 of the mixing part 5 by operating this. Even in such a configuration, if the shutter on the fertilizer storage unit 10 side and the shutter on the pesticide storage unit 11 side are alternately opened, the mixed state of the fertilizer and the agricultural chemical can be optimized.

  In the said embodiment, although the rotating plate 51 provided in the spreading | diffusion part 6 illustrated the example which provided the spreading | diffusion blade | wing 53 extended radially in the radial direction of the rotating plate 51 toward the outer peripheral side from the center part, this invention was illustrated. However, the present invention is not limited to this. For example, as shown in FIG.

  In the said embodiment, although the example which employ | adopted the mixing apparatus with a stirrer as what was called the stirrer mixer which attached many reed boards 46 to the rotating shaft 50 as the stirrer 45 provided in the mixing part 5 was illustrated, The invention is not limited to this, and the stirring device 45 is referred to as a so-called screw mixer in which a screw 60 (mixing member) is attached to the rotating shaft 50 as shown in FIG. A thing of suitable composition, such as what is called what is called a ribbon mixer which attached a stirring piece 61 (mixing member) as shown in Drawing 7 (b), etc., is employable.

  Here, in the agricultural spraying device 1 described above, the mixing unit 5 has a configuration in which the rotating shaft 50 is erected and the slat 46 is attached thereto, but the present invention is not limited thereto. Without, for example, the agricultural spraying device 70 shown in FIG. 8, it has a rotating shaft 71 (mixing side rotating shaft) to which the plate 46 of the mixing unit 5 is attached separately from the rotating shaft 50 to which the rotating plate 51 is attached, A configuration may be adopted in which the rotating plate 71 is equipped with a gutter plate 46, a screw 60, a stirring piece 61, and the like.

  More specifically, the agricultural spraying device 70 shown in FIG. 8 is mostly the same as the agricultural spraying device 1 described above, but the configuration of the mixing unit 75 (mixing means) is the same as that of the mixing unit 5 described above. Different. The mixing unit 75 employed in the agricultural spraying device 70 is provided with a rotating shaft 71 so as to cross the inside of the mixing chamber 76 (accommodating unit) formed below the mixing ratio adjusting unit 3. A large number of gutters 46 are helically attached. The rotating shaft 71 is connected to a power source such as a PTO (Power Take Off) shaft provided on a tiller or a tractor, a rotating shaft of a motor, or the like.

  The mixing chamber 76 is provided with an opening 77 serving as an inlet for fertilizer and pesticide at a position vertically below the fixed-side fertilizer opening 23 and the fixed-side pesticide opening 25 provided at the bottoms of the fertilizer storage unit 10 and the pesticide storage unit 11. ing. The opening 77 exists on one end side of the rotation shaft 71 disposed in the mixing chamber 76. An opening 78 serving as a discharge port for a mixture of fertilizer and agricultural chemicals is located at the bottom surface of the mixing chamber 76 at a position corresponding to the opposite side of the opening 77 (the other end side of the rotating shaft 71). Is provided. Below the opening 78, a spraying unit 6 having the same configuration as that provided in the agricultural spraying device 1 described above is provided. The opening 78 drops the mixture mixed in the mixing chamber 76 to a position away from the approximate center of the rotating plate 51 of the spraying unit 6, similarly to the opening 43 provided in the mixing unit 5 of the agricultural chemical spraying device 1 described above. It is opened at a position where it can be made.

  As shown in FIG. 8, the bottom surface of the mixing chamber 76 is configured to gradually incline downward from the opening 77 side toward the opening 78 side. That is, the bottom surface of the mixing chamber 76 has a downward slope toward the opening 78 side. Therefore, when fertilizer and agricultural chemicals are introduced into the mixing chamber 76 from the opening 77, these are gradually guided to the opening 78 side.

  In the agricultural spraying device 70 shown in FIG. 8, when fertilizer and pesticide are dispensed from the fertilizer container 10 and the agrochemical container 11, the fertilizer and pesticide are dispensed from the opening 77 into the mixing chamber 76. When the rotating shaft 71 is rotated in this state, the fertilizer and the agricultural chemical are gradually mixed toward the downstream side, that is, the opening 78 side while being mixed by the rotating plate 46 rotating in the mixing chamber 76. The mixture formed by mixing fertilizer and agricultural chemicals in the mixing chamber 76 falls from the opening 78 to the central portion of the rotating plate 51 of the spraying portion 6 disposed below or in the vicinity thereof. The mixture dropped on the rotating plate 51 is scattered under the influence of the centrifugal force generated by the rotation of the rotating plate 51, and is sprayed to the outside of the agricultural spraying device 70 from the spraying opening 56.

  If the rotating shaft 71 of the mixing unit 75 intersects the rotating shaft 50 of the rotating plate 51 (substantially orthogonal in the present embodiment) as in the agricultural spraying device 70 described above, the fertilizer container 10 and the pesticide are used. The interval between the accommodating portion 11 and the spraying portion 6, that is, the height of the mixing portion 75 can be suppressed. Moreover, if it is set as the above-mentioned structure, the distance from the opening 77 used as a fertilizer and an agrochemical to the opening 78 used as an exit can fully be ensured, and a fertilizer and a pesticide can fully be mixed. Therefore, if a configuration like the agricultural spraying device 70 is adopted, the fertilizer and the agricultural chemical can be sufficiently mixed and sprayed while making the device configuration compact.

  In the agricultural spraying device 70 described above, the configuration in which the bottom surface of the mixing chamber 76 is provided with a downward slope is illustrated, but the present invention is not limited to this, and the bottom surface may be substantially horizontal. Moreover, in FIG. 8 and the above-mentioned description, although the structure which attached the mortar board 46 to the rotating shaft 71 was illustrated, the structure which attached the screw 60 and the stirring piece 61 instead of the mortar board 46 similarly to the agricultural spraying apparatus 1. It is good.

  In the agricultural spraying devices 1 and 70 described above, the mixing sections 5 and 75 are those in which the mortar plate 46, the screw 60, and the stirring piece 61 are operated to mix the fertilizer and the agricultural chemical, but the present invention is limited to this. For example, instead of a configuration in which the gutter plate 46, the screw 60, and the stirring piece 61 are operated, a configuration in which a net-like member such as a wire net, punching metal, and expanded metal, a baffle plate, or the like may be arranged. That is, the agricultural spraying device 1,70 is not limited to the configuration in which fertilizer or pesticide is actively mixed using some power as in the mixing unit 5,75 described above, and the fertilizer or pesticide passes therethrough. It is good also as a structure which provided baffle members, such as a net-like member and a baffle plate, in the middle of the path | route to the spreading | diffusion part 6 to perform. In addition, the mixing sections 5 and 75 may be configured such that a gutter plate 46, a screw 60, and a stirring piece 61 are provided, and a net-like member such as a wire net, punching metal, or expanded metal, a baffle plate, or the like is disposed. According to such a configuration, the fertilizer and the agricultural chemical pass through the path in which the baffle members are arranged, thereby promoting the stirring of the fertilizer and the agricultural chemical, and the fertilizer and the agricultural chemical can be sprayed in a mixed state.

  Moreover, the agricultural spraying apparatus 1 and 75 are the structures which mix fertilizer and agrochemical actively using the power like the mixing parts 5 and 75 in the middle of the path | route to the spraying part 6 through which fertilizer and agrochemical pass. In addition to this, a configuration in which a baffle member such as a net-like member or a baffle plate may be provided. According to such a configuration, stirring of the fertilizer and the agricultural chemical can be further promoted, and the fertilizer and the agricultural chemical can be sprayed in a well-mixed state.

  The agricultural spraying device 1, 70 shown in the above embodiment was attached to a field cultivator or tractor and was operable by obtaining power from these, but the present invention is not limited to this, for example, A configuration in which a motor or an engine is separately provided as a power source is also possible. When it is set as this structure, it can be set as the structure which can use the agricultural spraying apparatus 1 and 70 independently, or can carry the agricultural spraying apparatus 1 and 70 and can use it.

  In the said embodiment, although the structure which formed the fertilizer accommodating part 10 and the agrochemical accommodating part 11 by partitioning the single accommodating part 2 with the partition plate 12, this invention is not limited to this, It is good also as a structure which provided the fertilizer accommodating part 10 and the agrochemical accommodating part 11 separately.

  Moreover, the agricultural spraying apparatuses 1 and 70 may have a configuration in which a mixing ratio adjusting unit 90 configured as shown in FIG. 10A is provided in place of the mixing ratio adjusting unit 3 employed in the above embodiment. Good. More specifically, as shown in FIG. 10A, the mixing ratio adjusting unit 90 is extended to two rotation shafts 91 that are provided so as to cross below the fertilizer storage unit 10 and the pesticide storage unit 11. The rolls 92 and 93 are mounted. The rotating shaft 91 is connected to a power source (not shown) and is rotatably supported by the main body of the agricultural spraying apparatuses 1 and 70.

  As shown in FIG. 10B, the feeding rolls 92 and 93 have a configuration in which a plurality of pockets 92b and 93b (concave portions) are provided at substantially equal intervals in the circumferential direction on the outer peripheral portion of the substantially cylindrical roll main bodies 92a and 93a. Has been. The feeding rolls 92 and 93 are arranged so that fertilizer and agricultural chemicals can be delivered to the pockets 92b and 93b from the openings provided at the bottoms of the fertilizer storage unit 10 and the agricultural chemical storage unit 11, respectively. The sizes of the pockets 92b and 93b are adjusted according to the mixing ratio of fertilizer and pesticide.

  The mixing ratio adjusting unit 90 rotates the rotating shaft 91 to rotate the feeding rolls 92 and 93, so that the fertilizer and the agricultural chemical accumulated in the pockets 92b and 93b can be discharged to the mixing unit 5 side at a predetermined ratio. it can. Further, the mixing ratio adjusting unit 90 can adjust the amount of fertilizer and agricultural chemicals dispensed to the mixing unit 5 by adjusting the rotation time (rotation amount) of the feeding rolls 92 and 93. Therefore, even if the agricultural spraying devices 1 and 70 adopt a configuration such as the mixing ratio adjusting means 90 instead of the mixing ratio adjusting unit 3 described above, the fertilizer and the agricultural chemical are supplied to the mixing unit 5 at a predetermined ratio. can do.

  The mixing ratio adjusting unit 90 described above has a configuration in which the feeding rolls 92 and 93 rotate together with the rotation of the rotating shaft 91. However, the present invention is not limited to this. The feeding rolls 92 and 93 may be configured to be independently operable by providing a mechanism capable of transmitting or interrupting power such as a clutch mechanism between the two. In such a configuration, the feeding rolls 92 and 93 can be operated alternately, and the fertilizer and the agricultural chemical can be alternately dispensed in the same manner as in the case where the mixing ratio adjusting unit 3 is provided.

  Further, as in the agricultural spraying device 100 shown in FIG. 11, in place of the mixing ratio adjusting unit 3 employed in the above embodiment, the mixing ratio includes feeding rolls 113, 114, 115 that can be operated independently. The adjustment unit 110 may be provided. Hereinafter, the configuration of the agricultural chemical spraying apparatus 100 will be described in detail with reference to the drawings. In addition, since the agricultural chemical spraying apparatus 100 has the characteristics in the structure of the mixing ratio adjustment unit 110 and the other parts have substantially the same structure as the above-described agricultural chemical spraying apparatuses 1 and 70, common parts have the same reference numerals. The detailed description is omitted. Moreover, since the agricultural spraying apparatus 100 can employ | adopt the structure similar to any of the mixing parts 5 and 75 employ | adopted as the above-mentioned agricultural spraying apparatus 1 and 70, or the spraying part 6, in FIG. , 75 and the spreader 6 are not shown and are omitted.

  The mixing ratio adjusting unit 110 has a roll shaft 111 inserted in the width direction of the agricultural chemical spraying apparatus 100 as shown in FIG. The roll shaft 111 is attached to the main body case 101 of the agricultural chemical spraying apparatus 100 so as to be slidable in the axial direction. The roll shaft 111 is connected to a power source such as a motor (not shown) and can rotate by receiving this power. A fork guide 112 is attached to the roll shaft 111. The roll shaft 111 can be moved in the axial direction via the fork guide 112.

  Three feeding rolls 113, 114, and 115 are rotatably mounted on the roll shaft 111. The feeding rolls 113 and 114 are located immediately below the fertilizer storage unit 10, and rotate around the roll shaft 111 to pay the fertilizer stored in the fertilizer storage unit 10 to the mixing unit 5 side. Can be put out. Further, the feeding roll 115 is located immediately below the pesticide storage unit 11, and when rotated around the roll shaft 111, the pesticide in the pesticide storage unit 11 can be dispensed to the mixing unit 5. The feeding roll 114 is shorter in the axial direction than the feeding roll 113, and the amount of fertilizer discharged per rotation is smaller than that of the feeding roll 113. Therefore, the mixing ratio adjusting unit 111 can adjust the amount of fertilizer discharged to the mixing unit 5 depending on which of the feeding rolls 113 and 114 is rotated, and can adjust the mixing ratio of the fertilizer and the agricultural chemical.

  Between the feeding rolls 113 and 114, clutch claws 116 and 116 are disposed so as to face each other. A clutch A 117 is provided between the feeding rolls 113 and 114. The clutch A 117 is fixed to the outer periphery of the roll shaft 111. A clutch claw 118 is attached to the side surface of the feeding roll 115.

The clutch 119 is provided with a clutch pawl 120 so as to face the clutch pawl 118 described above. A fork guide 121 is provided on the outer periphery of the clutch 119 and can be slid in the axial direction of the roll shaft 111 using the fork guide 121. Partitions 122 and 123 partition the feeding rolls 113 and 114 and the feeding rolls 114 and 115.

  In the state shown in FIG. 11, the mixing ratio adjusting unit 110 is in a state where both of the clutches A, B117, and 120 are disconnected. Therefore, even if power is transmitted from the power source (not shown) to the roll shaft 111, the power is not transmitted to the feeding rolls 113, 114, 115. The clutch B 119 slides the clutch B 119 in the axial direction using the fork guide 121 and engages the clutch pawl 120 with the clutch pawl 118 provided on the side surface of the feed roll 115 to apply torque to the feed roll 115. The feeding roll 115 can be rotated by transmission. The agricultural chemicals mainly used in the agricultural chemical storage unit 11 are paid out to the mixing unit 5 provided below the mixing ratio adjusting unit 110 as the feed roll 115 rotates.

  Further, the mixing ratio adjusting unit 110 moves the roll shaft 111 in the axial direction using the fork guide 121 and moves the roll shaft 111 in the left direction in FIG. , 114 is engaged with the clutch pawl 116 of the feed roll 113, torque is transmitted from the roll shaft 111 to the feed roll 113, and the feed roll 113 rotates. When the feeding roll 113 rotates, the fertilizer stored in the fertilizer storage unit 10 is paid out to the mixing unit 5. On the contrary, when the fork guide 112 is used to slide the roll shaft 111 in the right direction in FIG. 11, the clutch A 117 is engaged with the clutch pawl 116 of the feed roll 114 and the feed roll 114 rotates together with the roller shaft 111. The fertilizer in the fertilizer accommodating part 10 is paid out to the mixing part 5 side.

  Also for the agricultural spraying device 100 described above, predetermined rolls 113, 114, 115 are rotated by sliding the roll shaft 111 in the axial direction, and the rotation time of the feed rolls 113, 114, 115 is adjusted, or the roll The amount of fertilizer and pesticide dispensed can be adjusted by adjusting the amount of rotation of the shaft 111, for example. Moreover, it can be set as the structure which pays out a fertilizer and a pesticide alternately by sliding the roll axis | shaft 111 suitably.

  In the above-described mixing ratio adjusting unit 110, the example in which the two feeding rolls 113 and 114 are provided so as to feed out the fertilizer is illustrated. However, the present invention is not limited to this, and the feeding roll for feeding out the fertilizer is simple. Even if it is one structure, it is good also as a structure provided more. Further, in the above-described mixing ratio adjusting unit 110, the feeding roll 115 has a single configuration, but the present invention is not limited to this, and two feeding rolls 113 and 114 are provided for fertilizer dispensing. Similarly to the above, a plurality of feeding rolls may be provided, and all or part of them may be rotated so that the agricultural chemicals can be dispensed.
