In particular, in a so-called mid-mount fertilizer in which a fertilizer is mounted substantially at the center of the machine body, a fertilizer hopper for storing fertilizer and the like is disposed at the rear of the driver's seat. For example, in the technology shown in Japanese Patent Laid-Open No. 2001-25312, in a rice transplanter equipped with a fertilizer machine at the rear part of a traveling machine body and a planting part at the rear, a motor is provided in the fertilizer machine, A fertilizer amount sensor for detecting the fertilizer amount is disposed in the motor, and the motor is driven and controlled based on the detection of the fertilizer amount sensor.
[0003]
[Problems to be solved by the invention]
However, in the technique disclosed in Japanese Patent Laid-Open No. 2001-25312, since the fertilizer is provided at the rear of the traveling machine body, the weight balance of the machine body deteriorates depending on the state of the field, and it may not be possible to travel stably. . In addition, since the feeding device is arranged in the left-right direction at the rear of the driver's seat, there is a problem that the configuration behind the driver's seat becomes complicated. Moreover, although the traveling drive and the fertilizer application drive were synchronized, there was a case where accurate fertilization could not be performed due to wheel slip or the like. In addition, since the feeding device is juxtaposed in the left-right direction at the rear of the driver's seat and the fertilization position is located at the lower part of the planting part, it is transported by the hose from the feeding until it is fertilized on the farm field. Therefore, there is a problem that a time lag occurs between the start of work and the start of fertilization, the end of work and the end of fertilization, a portion that is not fertilized occurs at the start of work, and unnecessary fertilization is performed at the end of work.

The speed is calculated.
[0015]
Next, the fertilizer applicator 36 will be described with reference to FIGS. The fertilizer applicator 36 includes a fertilizer hopper 37 for putting fertilizer, a fertilizer feeding device 38 that is a fertilizer feeding portion for feeding the fertilizer by a certain amount, a joint 44 connected to a lower portion of the fertilizer feeding device 38, and a connection to the joint 44. A transport pipe 60 to be connected, a distributor 61 to be connected to the transport pipe 60 to distribute the transport fertilizer evenly, a flexible transport hose 40 to be connected to the distributor 61, and the transport hose 40 It comprises a groover 39 connected to the tip, a cylindrical air chamber 42 that sends compressed air to the joint 44, and a turbo blower blower 41 that supplies compressed air to the air chamber 42.
[0016]
The grooving device 39 is arranged at the bottom of the planting part 15 at the front side of the planting position of the center float 34 and the side floats 35 and 35, respectively, and forms a fertilizer by forming a groove for dropping the fertilizer. The air chamber 42 is installed horizontally at the front end of the transfer pipes 60 and 60 below the driver's seat 9, and communicates with the discharge port of the blower 41 at the left and right central portions of the air chamber 42. The blower 41 is a motor or engine. Driven by power from 2.
[0017]
In the present configuration example, the fertilizer hoppers 37 and 37 and the feeding devices 38 and 38 are disposed substantially at the front and rear of the traveling portion on both the left and right sides of the driver's seat 9, and the feeding roll 32 is rotatable in the feeding case. On the outer periphery of the feeding roll 32, the recesses into which fertilizer can be inserted are formed at regular intervals. Further, a driving motor 62 is provided as a feeding driving means on the side surface of the driving seat 9 of the feeding device 38, and the feeding roll 32 is rotationally driven by the driving motor 62, so that a certain amount of fertilizer in the recess is applied to the fertilizer hopper 37. It is transported downward from the side and fed out. The drive motor 62 is connected to the controller 57, and the controller 57 changes the rotational speed of the drive motor 62 in accordance with the traveling speed and the set value by the setting device 63 arranged on the side of the driver's seat 9. The fertilizer feed rate can be adjusted. The setter 63 sets the amount of fertilizer to be sprayed on the field area, and can easily change the set value without changing the roll or changing the volume of the recess. That is, as shown in FIG. 4, the rotational speed of the drive motor 62 is changed in proportion to the traveling speed. Therefore, when the traveling speed increases at the start of work, the rotational speed of the drive motor 62 is also proportional. If the vehicle travels at a constant traveling speed during work, the rotational speed becomes constant. When the vehicle is decelerated at the end of the work, the rotational speed also decreases. When traveling is stopped, the drive motor 62 also stops. The controller 57 and the setting device 63 can be arranged at any position of the machine body, and the feeding portion is not limited to a roll, and may be a pan-type or a belt-type.
[0018]
In addition, the distributor 61 is disposed behind the feeding device 38, and the distributor 61 is connected to the joint 44 side of the feeding device 38 via the transport pipe 60. Around the distributor 61, a plurality of (three in the present configuration example) transport hoses 40, 40, 40 are fitted at regular intervals, and the high-pressure air from the blower 41 is transported from the air chamber 42 to the transport pipe. 60 and the distributor 61 can be sent to the hoses 40, 40, 40. The distributor 61 is configured to distribute three fertilizers equally, but can also be configured to open and close by providing an electromagnetic valve or the like so that fertilizer can be applied according to the number of strips. Therefore, when the fertilizer fed from the feeding device 38 falls to the joint 44, it is transported to the distributor 61 through the transport pipe 60 by the air from the blower 41, and is equally distributed in three directions in the distributor 61. Then, it is conveyed to the planting part 15 by the conveyance hoses 40, 40, 40. However, in this configuration example, 6-row planting is described, but it can be applied to 4-row, 5-row, 8-row planting, and the like, and is not limited.
[0019]
In such a configuration, the weight balance of the traveling vehicle 1 is improved because the heavy fertilizer 36 and the fertilizer such as the fertilizer feeding device 38 and the like, which are heavy, are disposed on the left and right sides of the driver's seat 9. It is possible to travel stably, and the fixing structure can be simplified by effectively using the space on the side of the driver's seat 9. Moreover, since the structure behind the driver's seat 9 can be simplified and the overall length can be made shorter than that of a conventional mid-mount fertilizer applicator, the number of work steps in the pillow can be reduced. Furthermore, since the weight of the balance weight provided in front of the airframe can be reduced, the weight of the airframe can be reduced. In addition, the replenishment of the fertilizer can be easily put into the fertilizer hopper 37 according to the steps, and even when the remaining fertilizer is low, the confirmation can be easily made, the timing of the replenishment can be easily measured, and the fertilizer after the work is finished. Can be easily taken out.
[0020]
Further, the feeding device 38 is driven by the drive motor 62, and the drive motor 62 is connected to the controller 57 connected to the rotation speed sensor 55, and the controller 57 adjusts the traveling speed and the set amount by the setting device 63. In addition, since the feed amount of the fertilizer can be adjusted, the fertilizer application amount can always be maintained appropriately, and highly accurate fertilization work can be performed. That is, since the fertilization work is necessary only at the time of planting work, when the planting part 15 is raised at the time of turning, etc., the grounding ring 53 is also raised, the value from the sensor 55 is not input, and the feeding is stopped, Wasteful fertilization is no longer performed.
[0021]
Next, the fertilizer applicator of the embodiment will be described with reference to FIGS. The fertilizer applicator 64 includes a fertilizer hopper 65 for putting fertilizer, a fertilizer take-out portion 66, a joint 67 connected to the lower portion of the fertilizer take-out portion 66, a transport pipe 68 connected to the joint 67, and the transport pipe 68. A distributor 69 that is connected to distribute the transported fertilizer evenly, a flexible transport hose 70 that is connected to the distributor 69, a fertilizer feeding device 78 that is connected to the tip of the transport hose 70, and a grooving device 79, a cylindrical air chamber 80 that sends compressed air to the joint 67, and a turbo blower type blower 81 that supplies compressed air to the air chamber 80.
[0022]
The grooving device 79 is disposed at the bottom of the planting portion 15 at the front side of the center float 34 and the side floats 35 and 35, respectively, and forms a fertilizer by forming a groove for dropping the fertilizer. The air chamber 80 is installed at the front end of the transfer pipes 68 and 68 below the driver's seat 9 and communicates with the discharge port of the blower 81 at the left and right central portions of the air chamber 80. The blower 81 is a motor or engine. Driven by power from 2.
[0023]
A fertilizer feeding device 78 is provided in the vicinity of the planting position at the bottom of the planting unit 15, and the fertilizer feeding device 78 stores a storing portion 78 a for storing fertilizer conveyed from the fertilizer hopper 65 and a feeding portion 78 b for feeding fertilizer. It is composed of A feeding roll 71 is rotatably supported on a feeding portion 78b of the fertilizer feeding device 78, and recesses into which fertilizer can be inserted are formed on the outer periphery of the feeding roll 71 at regular intervals. A drive motor 82 is provided as a feed drive means on the side surface of the fertilizer feed device 78, and the feed roll 71 is rotationally driven by the drive motor 82, so that a certain amount of fertilizer in the recesses is downward from the reservoir 78a side. It is transported and fed out. The drive motor 82 is connected to the controller 57, and the controller 57 changes the rotational speed of the drive motor 82 in accordance with the traveling speed and the set value by the setting device 63 disposed on the side of the driver's seat 9. The feed amount of fertilizer can be adjusted. The setter 63 sets the amount of fertilizer to be spread on the field area. In addition, fertilizer can be applied for each line. That is, as shown in FIG. 4, the rotational speed of the drive motor 82 is changed in proportion to the traveling speed. Therefore, when the traveling speed increases at the start of work, the rotational speed of the drive motor 82 is also proportional. If the vehicle travels at a constant traveling speed during work, the rotational speed becomes constant. When the vehicle is decelerated at the end of the work, the rotational speed also decreases. When the traveling is stopped, the drive motor 82 also stops. However, the feeding rolls 71 b of the fertilizer feeding devices arranged side by side in the left-right direction are provided on a single drive shaft via an electromagnetic clutch. As a configuration for driving by one drive motor 82, each electromagnetic clutch can be connected to the controller 57 to control the roll drive. Further, the controller 57 and the setting device 63 can be arranged at arbitrary positions on the machine body, and the feeding portion is not limited to the roll, but may be a pan-type or a belt-type.
[0024]
Further, the tip portion of the hose 70 is fitted and communicated with each storage portion 78a of the fertilizer feeding device 78, and the lowest position sensor 83 is provided on the lower side surface of the case of the storage portion 78a, and the highest position is provided on the upper side surface. A sensor 84 is provided to detect the amount of fertilizer stored in the storage portion 78a. The lowest sensor 83 and the highest sensor 84 are connected to the controller 57 so that the fertilizer remaining amount in the storage section 78a can be detected. However, since approximately the same amount is fed from the fertilizer feeding device 78 of each strip, the lowest sensor 83 and the highest sensor 84 may be arranged in any one storage section 78a of each strip.
[0025]
Further, the fertilizer hoppers 65 and 65 are disposed in the vicinity of the driver's seat 9, and in the present embodiment, disposed on the front and rear sides of the traveling unit on both the left and right sides, and the fertilizer extraction unit 66 below the fertilizer hopper 65 has a shutter. 86 is slidably arranged so that the opening below the fertilizer hopper 65 can be opened and closed. The shutter 86 is opened and closed as a cylinder 87 and an actuator by a shutter driving device 85 including a motor 88. The motor 88 is connected to the controller 57, and the controller 57 sets the fertilizer remaining amount in the storage section 78a. At the same time, the motor 88 is driven and the cylinder 87 is expanded and contracted to open and close the shutter 86 of the fertilizer inlet, thereby adjusting the amount of fall from the fertilizer hopper 37, and the amount of fertilizer transported to the fertilizer feeding device 78. Adjustable. However, a solenoid can be used instead of the motor and the cylinder. That is, when the fertilizer is fed out during the work and the fertilizer is reduced to the position where the lowest sensor 83 is provided in the storage portion 78a of the fertilizer feeding device 78, the controller 87 contracts the cylinder 87 to open the shutter 86, and fertilizer is applied. Fertilizer is introduced from the hopper 65 and conveyed and supplied to the storage section 78a. When the fertilizer increases to the position of the highest sensor 84, the controller 57 extends the electric cylinder 87 and closes the shutter 86, so that the fertilizer is not fed from the fertilizer hopper 65 and the conveyance to the storage section 78a is stopped. I am doing so. The blower 81 can be driven in conjunction with the opening / closing control of the shutter 86. That is, since it is useless to always operate the blower 81, when the blower 81 is driven by a motor, when the lowest sensor 83 is turned on, the blower 81 is driven to increase the air volume and the shutter driving device 85. When the shutter 86 is opened and the highest sensor 84 is turned ON, the shutter 86 is closed and the blower 81 is stopped when the fertilizer reaches the storage section 78a.
[0026]
The distributor 69 is disposed behind the fertilizer hopper 65, and the distributor 69 is connected to a joint 67 through a transport pipe 68. Around the distributor 69, a plurality of (three in this embodiment) transport hoses 70, 70, 70 are fitted at regular intervals, and the high-pressure air from the blower 81 is transported from the air chamber 80 to the transport pipe. 68 and a distributor 69 so that they can be sent to the hoses 70, 70, 70. The distributor 69 is configured to distribute three fertilizers equally, but can also be configured to be opened and closed so as to be transported to the storage unit 78a where the fertilizer is reduced by providing an electromagnetic valve or the like. The position where the fertilizer hopper 65 is disposed may be in the vicinity of the driver's seat 9 and is not limited to the left and right sides of the driver's seat 9. Furthermore, it is also possible to arrange a fertilizer hopper 65 and a distributor 69 below the step. Therefore, when the fertilizer thrown in from the fertilizer hopper 65 falls to the joint 67, it is transported to the distributor 69 via the transport pipe 68 by the air from the blower 81, and is equally distributed in three directions in the distributor 69. Then, it is conveyed by the conveying hoses 70, 70, 70 to the storage part 78 a of the fertilizer feeding device 78. However, in this embodiment, six-row planting is described, but it can be applied to four-row, five-row, and eight-row planting, and is not limited.
[0027]
In such a configuration, since heavy members such as the fertilizer hopper 65 and fertilizer of the fertilizer applicator 64 are disposed on both the left and right sides of the driver's seat 9 and the fertilizer feeding device 78 is disposed below the planting portion 15, the traveling vehicle 1 The weight balance of the vehicle can be improved, the vehicle can travel stably, and the fixing structure can be simplified by effectively using the space on the side of the driver's seat 9. Further, the structure behind the driver's seat 9 can be simplified, and the replenishment of fertilizer can be easily put into the fertilizer hopper 65 in steps, so that even when the remaining fertilizer is low, the confirmation can be easily performed. It is easy to measure the timing of replenishment, and it is easy to take out fertilizer after work.
[0028]
Further, the fertilizer feeding device 78 is driven by the drive motor 82, and the drive motor 82 is connected to the controller 57 connected to the rotation speed sensor 55, and the controller 57 sets the running speed and the set amount by the setting device 63. Since the feed amount of fertilizer can be adjusted according to the fertilizer amount, the fertilizer amount can always be properly maintained and high-precision fertilization work can be performed. That is, since the fertilization work is necessary only at the time of planting work, when the planting part 15 is raised during turning, etc., the grounding ring 53 is also raised and the value from the rotational speed sensor 55 is not input, and feeding is stopped. As a result, useless fertilization is not performed.
[0029]
Further, the cylinder 87 connected to the shutter 86 is driven to extend and contract by a motor 88, the motor 88 is connected to the controller 57, and the controller 57 matches the remaining amount of fertilizer in the storage portion 78 a of the fertilizer feeding device 78. Since the amount of fertilizer transported from the fertilizer hopper 65 can be adjusted, the remaining amount of fertilizer in the reservoir can be properly maintained, and unnecessary fertilization can be prevented. Moreover, since it suffices to store only a necessary amount of fertilizer in the storage part, the volume of the storage part can be reduced, and an increase in the weight of the planting part can be suppressed. However, in this embodiment, the side fertilizer has been described, but it can also be applied to a seeder, a chemical spreader, and the like.
