This no-tillage direct sowing machine is used by being pulled by a tractor that is a towing vehicle, and as shown in FIGS. 1 to 4, one of the left and right ends of the front part of the airframe 1 (the left end in the embodiment) is grounded. A wheel 2 is arranged, and the grounding wheel 2 can move up and down with respect to the machine body 1 via a chain case 3 and is urged downward via a compression spring (not shown). 1 is supported. A grooved wheel device A is arranged along the lateral direction (left-right direction) of the machine body 1 behind the grounding wheel 2 in the machine body 1. This grooved ring device A is configured such that a large number of grooved wheels W are integrally attached to the grooved ring drive shaft 4 with an interval (about 20 cm) corresponding to the gaps to be formed. As shown in FIG. 5, the grooved ring W includes a grooved ring main body 6 in which the outer peripheral portions of a pair of curved disks 5 are welded to form a V-shaped outer peripheral portion, and the groove It consists of a pair of flange rings 7 that are respectively applied to both sides of the ring body 6 and are welded integrally to the outside of each curved disk 5. It is the structure where the outer periphery protruded. The grooved ring body 6 is integrated with the outer peripheral surface of the pipe-shaped mounting body 8 by welding, and the grooved ring W is mounted on the mounting body 8, the grooved wheel drive shaft 4, and the mounting pin 10 penetrating the mounting body 8. In addition, it is integrally attached to the grooved wheel drive shaft 4 through the fixing bolt 9 for preventing rattling. Then, as shown in FIG. 5, when the grooved wheel drive shaft 4 is driven to rotate and the machine body 1 moves forward, the grooved ring body 7 constituting the grooved wheel W is in contact with the soil surface G, Grooves are formed on the soil surface G by groove forming portions 6 a protruding from the collar ring body 7 in the ring body 6.
[0004]
In addition, a sowing apparatus B that simultaneously performs sowing and fertilization is mounted in the sowing groove V immediately after the grooving in the upper part of the machine body 1 after the grooving ring apparatus A. That is, a large number of hoppers 11 that can separate and accommodate seeds and fertilizers are disposed above and behind each of the grooved wheels W that constitute the grooved wheel device A, and each hopper 11 is placed inside thereof. The separation plate 12 is separated into a seed storage chamber 13 and a fertilizer storage chamber 14.

The sowing conduit 16 for dropping and guiding the mixture of seeds and fertilizer is connected to the formed sowing groove V (see FIGS. 2 and 5). Since the seeding conduit 16 is made of a flexible material such as a vinyl hose having an inner diameter of about 25 mm, when the discharge port 16a at the tip is in contact with the upper edge of the seeding groove V, the seeding conduit 16 bends freely. . A cover soil chain 17 is connected to the rear of the grooved wheel device A in the machine body 1 at the same position as each grooved wheel W along the axial direction of the grooved wheel drive shaft 4. The discharge port 16a at the lower end of the sowing conduit 16 has a length that travels while being guided by the sowing groove V while being in contact with the sowing groove V in the sowing state. The weight 17a connected to the rear end of the soil covering chain 17 has a predetermined length at the tip of the soil surface G so that the soil on both sides of the sowing groove V can be shaved and dropped into the sowing groove V in the sowing state. It is long enough to touch the ground.
[0005]
Further, as shown in FIG. 4, a cylindrical casing 18 is horizontally disposed in front of the receiver 15 in the airframe 1, and a drive shaft support bracket 19 is integrally formed downward at both ends thereof. The grooved wheel drive shaft 4 is rotatably supported at the lower end of each drive shaft support bracket 19. A transmission shaft 21 is housed in one portion (right half) of the cylindrical casing 18 that is divided in the longitudinal direction, and both ends thereof are supported. The inner end of the transmission shaft 21 is connected to the transmission shaft 21. The power of the tractor as a towing vehicle is transmitted from the orthogonal input shaft 22 to the transmission shaft 21 via the bevel gears 23a and 23b, and the chain gear 24 attached to the outer end portion (left end portion) of the transmission shaft 21; An endless chain 26 is hung between the grooved wheel drive shaft 4 and a chain gear 25 attached to one end of the grooved wheel drive shaft 4.

The PTO shaft (not shown) of the tractor and the input shaft 22 of the no-tillage direct sowing machine are connected via a universal joint (not shown), and the power of the tractor is driven by the grooved wheel via the transmission shaft 21. Each grooved wheel W transmitted to the drive shaft 4 and attached thereto is driven to rotate. One of the pair of left and right drive shaft support brackets 19 also serves as a chain case that houses the chain gears 24 and 25 and the endless chain 26. The grounding wheel 2 is driven to rotate as the machine body 1 travels. In FIG. 4, the input shaft 22 is vertically arranged on the drawing for the purpose of illustration, but the actual arrangement is almost horizontal.
[0007]
Further, as shown in FIGS. 1 to 3, a pair of lower support rods 27 are provided at a predetermined distance in the longitudinal direction at a portion extending from the center of the cylindrical casing 18 to the front of the airframe 1 in the front oblique direction. The upper support rod 28 is fixed to the center of the pair of lower support rods 27 so as to face the front obliquely upward, and the pair of lower support rods 27 and one upper support rod 28 are fixed. A quick hitch M that is connected to a three-point link hitch L attached to the rear portion of the tractor and lifts the airframe 1 is attached to the front end portion of the tractor.
[0008]
The body 1 of the no-tillage direct sowing machine having the above configuration is connected to the tractor via the quick hitch M attached to the front part thereof and the three-point link hitch L attached to the rear part of the tractor, and is pulled. Go up and down. In FIG. 1 and FIG. 2, 29 indicates the top link of the three-point link hitch L.
[0009]
2 and 5, when the airframe 1 is pulled by the tractor and travels in the direction of arrow P, the power of the tractor is transmitted to the grooved wheel drive shaft 4, and each grooved wheel W is in the down cut state. While being driven and rotated, the grounding wheel 2 moves forward for grounding and is driven to rotate, so that the rotational force of the grounding wheel 2 is fed out in the hopper 11 via a transmission mechanism (not shown). (Not shown), the seed K and the fertilizer separated and accommodated in the accommodation chambers 13 and 14 in the hopper 11 are fed out, and both are mixed in the receiver 15 immediately below, The mixture is fed out by an amount proportional to the traveling speed of the airframe 1. As shown in FIG. 5, due to the driving rotation of each grooving wheel W, a large number of sowing grooves V having a depth corresponding to the length of the grooving portion 6 a of the grooving wheel body 6 are formed in the field. It is formed with the same pitch (Q) as the pitch of the multiple grooved wheels W attached to the drive shaft 4. The mixture of seed K and fertilizer is dropped and supplied to the sowing groove V immediately after formation through the sowing conduit 16, sowing and fertilization are simultaneously performed on the bottom of the sowing groove V, and immediately after that, the covering soil chain A small amount of soil is dropped into the sowing groove V by 17 weights 17a and is covered with seed K and fertilizer.
[0010]
Then, as described above, the body 1 of the no-tillage direct sowing machine is pulled by the tractor and seeded in the sowing groove V immediately after the grooving, before the start of the sowing groove V and after the end of the molding. Rotate 180 ° in the state where the machine body 1 is raised, and sew a new sowing groove V group next to the sowing seed sowing groove V group to perform the sowing work. Here, at the time of turning, if the tractor driver operates the clutch to cut off the power transmission from the tractor's PTO shaft to the no-tillage direct seeder side, each grooved wheel W stops rotating. No problem. However, if the body 1 of the no-tillage direct sowing machine is lowered without interrupting the power transmission, that is, after performing the turning work while each grooved wheel W is rotating, as shown in FIG. Since each grooving ring W in the middle cuts the soil surface G, the body 1 is lowered with respect to the soil surface G. As a result, the discharge port 16a at the tip (lower end) of the sowing conduit 16 may bite into the soil surface G, and the discharge port 16a may be clogged with soil U. This defect is more noticeable when the soil surface G is softer. Become. As a result, the seed K and the fertilizer are not released from the sowing conduit 16, and sowing and fertilization using the no-tillage direct sowing machine cannot be performed smoothly.
[0011]
[Problems to be solved by the invention]
The problem of the present invention is that in the above-mentioned no-tillage direct sowing machine, even if the machine is turned to the ground after turning the machine before the start of the sowing groove forming and after the end of the forming, the soil is put into the discharge port at the tip of the sowing conduit. It is to be able to smoothly carry out no-tillage direct sowing work so as not to clog.
[0012]
[Means for Solving the Problems]
The invention according to claim 1 for solving the above-mentioned problem is a grooved ring in which a large number of grooved wheels are attached to a grooved wheel drive shaft disposed and supported in the left-right direction of the machined body at a predetermined interval. And a seeding device for dropping seeds through a seeding conduit into a seeding groove formed by each grooved ring of the grooved ring device, and pulled by a tractor and immediately after the channeling A non-tillage direct sowing machine for sowing, comprising a stand device in which a grounding body is rotatably connected to the rear of the machine body at the lower end of a support leg attached substantially vertically to the front part of the machine body, The stand device has a configuration in which left and right ends of a sled-like grounding body are rotatably connected to lower ends of a pair of left and right legs, and the grooved wheel device is in a state where the machine body is lowered and stopped. The grounding body is grounded in a state where it is separated from the soil surface or does not penetrate deeply into the soil. , Together with the machine body is supported, in the state in which the aircraft starts to move forward, said grounding member is bent backward, it is characterized in that a configuration in which the aircraft is reduced.
[0013]
According to the first aspect of the present invention, when the airframe of the no-tilt direct sowing machine connected to the rear part of the tractor is turned by 180 ° before and after the start of forming the sowing groove, the support leg is lowered when the airframe is lowered. The sled-like grounding body that is pivotally connected to the lower end portion of the head is positioned directly below the support leg due to its own weight, so that the grounding body is grounded, and the machine body has a grooved ring device. Temporarily supported in a state separated from the soil surface. For this reason, each groove ring of the groove ring device does not bite into the soil even if it is still rotating, and the aircraft does not fall down. Therefore, even if the aircraft is temporarily stopped, the tip of the seeding conduit is released. The exit will not be filled with soil.
[0014]
In addition, when the aircraft starts moving forward with the sled-shaped grounding body touching the ground, and the grooved wheel device is separated from the ground and the aircraft is supported, the grounding surface is grounded to support the aircraft. Since the machine body (support leg) moves forward with the grounding body being left as it is, the grounding body is bent backward with respect to the support leg. For this reason, the aircraft descends with respect to the soil surface while moving forward, so that the seeding groove is formed by each rotating groove, and the discharge port at the tip of the seeding conduit is formed at the upper edge of the seeding groove immediately after the preparation. By being guided, seeds are released smoothly and sown. Further, since the grounding body bent toward the rear of the machine only slides on the soil surface before the sowing of the sowing groove, there is no adverse effect on the grooving work by the grooving ring.
[0015]
Further, the stand device constituting the invention of claim 1 is configured such that the left and right end portions of the sled-like grounding body are rotatably connected to the lower end portions of the pair of left and right legs. When the airframe is temporarily supported in a state of being separated from the soil surface, the support state is stable, and when the airframe advances in this state, the grounding body is reliably bent to the rear of the airframe.
[0016]
Further, the stand device constituting the invention of claim 1 is configured such that the left and right ends of the sled-like grounding body are rotatably connected to the lower ends of the pair of left and right legs. The stand device of the invention of Item 2 is different in that the left and right ends of the roller-shaped grounding body are rotatably connected to the lower ends of the pair of left and right legs via a link body. Thus, in the invention of claim 2, since the grounding body is in the form of a roller, the rearward folding of the machine body is ensured, and the roller-shaped grounding body bent rearward rolls on the soil surface. Has the advantage of being pulled with a small resistance.
[0017]
Further, the invention of claim 3 is the invention of claim 1 or 2 , wherein the grounding body is constituted by a pair of split grounding bodies that are divided into left and right parts and arranged at predetermined intervals in the left and right direction, Each divided grounding body is connected to a pair of left and right legs so as to be rotatable. Since the grounding body is composed of a pair of left and right divided grounding bodies and the total length of the grounding body is shortened, the sliding resistance during groove formation is reduced.
[0018]
According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the stand device includes a stopper that prevents the grounding body from rotating forward of the airframe. Yes. When the grounding body lowers and supports the aircraft, or when the aircraft advances while supporting the aircraft, the grounding body rotates forward to ensure that the grounding body becomes an obstacle when the aircraft is moving forward. Can be prevented.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to a plurality of embodiments shown in FIGS. In addition, since the basic composition of the no-tillage direct sowing machine and its operation are the same as those described in the section “Prior Art”, the stand devices S _{1 to} S _{4 according} to the present invention, Only the relevant part will be described. As shown in FIGS. 1 to 3 and 6, the stand device S ₁ of the first embodiment is substantially vertical and has a predetermined interval in the lateral direction at the center in the lateral direction of the front portion of the body 1. And a pair of support legs 31 integrally attached to the machine body 1 and a sled-like grounding body T ₁ rotatably connected to the lower ends of the pair of support legs 31. . That is, the pair of lower support rods 27 are integrally attached with mounting rods 33 that are longer than the distance between the pair of lower support rods 27 in the lateral direction. Projecting by a predetermined length in the lateral direction. A connecting rod 34 is integrally attached to the upper end portions of the pair of support legs 31 substantially horizontally toward the rear, and the rear end portion of each connecting rod 34 is attached to both ends of the mounting rod 33 via brackets 32. Are attached together.
[0020]
In addition, the grounding body T ₁ is a structure in which a pair of pipe bodies 35 arranged in parallel at a predetermined interval are integrally connected by plate bodies 36 on the upper and lower surfaces thereof, and as a whole “sledge shape”. Presents. At both ends of the tread T _1, and connecting bracket 37 of the triangular shape is secured, the ground member T ₁ is the portion of each connecting bracket 37 of the right and left ends, via a connecting pin 38 of each support leg 31 the lower end It is connected with the part so that rotation is possible. For this reason, when the whole body 1 of the no-till direct sowing machine is lifted from the soil surface G, the grounding body T ₁ constituting the stand device S ₁ is suspended from the pair of support legs 31 at both left and right ends thereof. It is arranged immediately below. When the body 1 is lowered while the entire body 1 is lifted from the ground surface G, the grounding body T ₁ constituting the stand device S ₁ first contacts the ground surface G, and the ground ring 2 and the soil covering chain 17 are connected. other parts are excluded, while no ground on the soil surface G, the whole of the machine body 1 is temporarily supported by a stand device S ₁ [Figures 1 and 6 (b) refer to Fig. Particularly, since the bottom surface of the grounding body T ₁ of the stand device S ₁ is flat, there is an advantage that the temporary support state is stabilized.
[0021]
For this reason, when the body 1 of the non-tilling direct sowing machine connected to the rear part of the tractor is turned 180 ° before and after the formation of the sowing groove V in the field, the support leg 31 is lowered when the body 1 is lowered. Since the sled-like grounding body T _{1 that} is rotatably connected to the lower end portion of the body is positioned directly below each supporting leg 31 by its own weight, the airframe 1 excludes the grounding ring 2 and the soil covering chain 17. Thus, the machine body 1 is temporarily supported by the stand device S ₁ in a state where the grounding body T ₁ is first grounded and each grooved ring W is separated from the soil surface G. For this reason, each groove ring W of the groove ring apparatus A does not bite into the soil even if it remains rotating, and the machine body 1 does not fall down. Therefore, even if the machine body 1 is temporarily stopped, the sowing conduit Since the discharge port 16a at the tip of 16 does not enter the soil, the discharge port 16a is not clogged with soil.
[0022]
In the above state, that is, in the state where the machine body 1 is temporarily stopped and temporarily supported while the grooved wheel device A is separated from the soil surface G by the stand device S ₁ , the machine body 1 starts to advance. Since the grounding body T ₁ that is grounded on the ground surface G and supports the body ₁ is left as it is, the body 1 (the pair of supporting legs 31) moves forward, so that the grounding body T ₁ is attached to the pair of supporting legs 31. On the other hand, it is relatively retracted and bent back (see FIGS. 2 and 6 (b)). As a result, the airframe 1 descends with respect to the soil surface G while moving forward, so that the sowing groove V is grooved by each rotating grooving wheel W and sowing on the upper edge of the sowing groove V immediately after the grooving. The discharge port 16a at the tip of the conduit 16 is guided, and the seed K is discharged smoothly and sown. Further, while the machine body 1 is moving forward and performing the sowing operation, the grounding body T ₁ bent rearward of the machine body ₁ only slides lightly on the soil surface G before the sowing groove V is formed. There is no fear of breaking the grooved sowing groove V, and the grooving work by the grooving ring W is not adversely affected.
[0023]

That is, one end portion in the longitudinal direction of each link body 41 is connected to the lower end portion of each support leg 31 via a fulcrum pin 42, and the other end portion is connected to the grounding body T ₂ via the connection shaft 43. It is rotatably connected to the end face. Further, a stopper plate 44 is integrally attached to the front ends of the lower ends of the pair of support legs 31 so as to prevent the link body 41 from rotating from the substantially vertical position to the front of the machine body 1.
[0024]
For this reason, when the body 1 of the no-tillage direct sowing machine is lifted upward, as shown by the solid line in FIG. 7, the link bodies 41 at both ends become substantially vertical, and the grounding body T ₂ is supported by a pair of supports. It is arranged in a state of being suspended just below the legs 31. When the machine body 1 is lowered in this state, the roller-shaped grounding body T ₂ is prevented from rotating forward of the machine body 1 by the action of the stopper plates 44 at both the left and right ends. Temporarily supported by a grounding body T ₂ connected to the lower ends of the pair of support legs 31 via a pair of link bodies 41 in a substantially vertical posture. For this reason, even if each grooving wheel W is spaced apart from the soil surface G and each grooving wheel W rotates, it does not bite into the soil surface G. Accordingly, the soil does not clog the discharge port 16a at the tip of the sowing conduit 16.
[0025]
Further, when the airframe 1 moves forward in the temporary support state of the airframe 1 described above, the roller-shaped grounding body T ₂ is connected to each support leg 31 (airframe 1) as shown by a two-dot chain line in the partial enlarged view of FIG. ) Relative to each other and bent backward with respect to each support leg 31 to lower the body 1. As a result, the seeding groove V is formed by each rotating groove groove W, and the discharge port 16a at the tip of the seeding conduit 16 is guided to the upper edge of the seeding groove V immediately after the groove formation. The soil does not clog 16a. Stand device S ₂ of the present embodiment, since the grounding member T ₂ is a roller-shaped, is advantageous resistance is small when being towed bent rearward.
[0026]
Further, the grounding body T ₃ constituting the stand device S ₃ shown in FIG. 8 is a pair of divided grounding bodies T ₃₁ having a plate shape that is divided in the left-right direction and arranged at a predetermined interval in the left-right direction.
