DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
1 and 2 show a rice transplanter with a fertilizer application device, and a pair of left and right front wheels 2 and 2 and rear wheels 3 and 3 as running wheels are installed before and after a vehicle body 1. A steering device 6 having an operation box 4 and a steering handle 5 is installed at the front upper part of the vehicle body, and a seedling planting device 7 that can be moved up and down is provided at the rear part of the vehicle body. A driver's seat 8 is installed on the rear side of the control device 6, an engine E for transmitting power to each part of the rice transplanter is mounted on the lower side of the driver's seat, and a rear step 9 is provided on the rear side of the driver's seat. Yes. In FIG. 1, a shallow layer fertilizer 13 described later is omitted.
[0007]
The seedling planting device 7 includes a seedling loading tank 10 that reciprocates left and right, a planting rod 11 that cuts out one seedling and transplants it into the soil, a float 12 that leveles the seedling planting surface, that is, a side float 12L, 12R, center float 12C and the like.
The float 12 is moved up and down by a turning operation of a shaft 12s installed on the planting frame UF, and the float 12 is connected to the stay 12 by a pin shaft 12p. Is configured to move up and down.
[0008]
The shallow layer fertilizer 13 is comprised as follows. A pair of shallow tanks 14, 14 are arranged and fixed long in the front-rear direction at the left and right sides of the vehicle body 1, near the rear outside of the driver's seat 8 and outside the rear step 9, and the lower part is connected by a pipe 15. Yes. Each shallow tank 14, 14 is provided with a liquid fertilizer supply port at a position outside the upper surface, and is provided with a cap 16. A shallow fertilizer application pump 17 is provided behind the driver's seat 8 and immediately below the rear step. When this is operated by the power of the engine E, the liquid fertilizer in the pipe 15 is sucked from the suction pipe 18 and from the six discharge pipes 19. It is supposed to exhale.
[0009]
A horizontal shaft 22 is rotatably supported on a support plate 21 protruding from the stay 20. The nozzle 23 bent in a reverse character shape is fixed to the horizontal shaft 22 and is configured to rotate integrally. The nozzle 23 is slightly behind the overhanging portion 12a of the float 12 from the implantation position by the implantation rod 11. Arranged inside. When the lever 24 made of an elastic plate is rotated, the nozzle 23 rotates with the horizontal shaft 22 and stops when the hand is released. The nozzle 23 is moved up and down by the above-described rotation operation. , And protrudes downward from the lower surface of the float 12 or is stored along the lower surface. The protruding state is when fertilizer is dispersed, and the stored state is when the aircraft is moving or when the aircraft is stored. It is. Then, the rear end of the discharge pipe 19 is connected to the front end of each nozzle 23 by a flexible tube 25, and the liquid fertilizer discharged from the shallow layer fertilizer pump 17 is transplanted from the nozzle 23 by the planting basket 11. Near the side of the ground, it is sprayed shallower in the mud than the ground surface.
[0010]
The deep layer fertilizer 26 is comprised as follows. A pair of deep-layer fertilization tanks 27, 27 are disposed on both the left and right sides of the operation box 4, and the lower part is communicated with a pipe 28. A liquid fertilizer supply port is provided on the upper surface of each tank 27 and a cap 29 is provided. A deep-layer fertilization pump 30 that sucks and discharges liquid fertilizer in the tanks is installed below the rear step 9 at a position lower than the left and right paste tanks 27, 27. When the deep layer fertilization pump 30 is operated by the power of the engine E, the liquid fertilizer in the deep layer fertilization tank 27 is sucked through the pipe 28 and discharged from the three discharge pipes 31.
[0011]
A rotating tube 33 is rotatably supported on a stay 32 fixed to the rear portion of the float 12. The nozzle 34 bent in a reverse-helix shape is inserted into the hole 32a of the stay 32 and the hole 12b of the float 12, the rear end protrudes below the float 12, and the front end is fixed to the rotating tube 33 so as to be integrated. It is the structure which rotates to. When the lever 35 made of an elastic plate is turned, the nozzle 34 is turned together with the turning tube 33, and when the hand is released, the nozzle 34 stops at the turned position. It is configured to swing up and down and protrude downward from the lower surface of the float 12 or to be stored in a groove 36 provided on the lower surface. Then, the rear end of the discharge pipe 31 is connected to the rotating pipe 33 of each nozzle 34 by a flexible tube 37, and the liquid fertilizer discharged from the deep layer fertilizer pump 30 is transferred to the implantation rods 11 on both sides of the float 12. Between the pair of seedlings transplanted in this way, each nozzle 34 is sprayed deeply into the mud from the ground surface.
[0012]
The fertilizer pumps 17 and 30 are provided immediately below the rear step 9, but the fertilizer tank 27 is provided higher than the fertilizer pump 30. Therefore, even if the path of the pipe 28 connecting the deep layer fertilization tanks 27, 27 and the deep layer fertilization pump 30 passes once below the step floor 41 of the traveling vehicle body 1, the liquid fertilizer of the deep layer fertilization tanks 27, 27 It is reliably supplied to the fertilization pump 30 for deep layer, the pump efficiency is improved, and the residual liquid fertilizer in the tank is also reduced.
[0013]
The transmission 38 is provided on the rear step 9 behind the driver's seat 8 and is configured such that the amount of liquid fertilizer delivered by the pump 30 can be arbitrarily changed by operating the transmission lever 39. In the figure, reference numeral 40 denotes a spare seedling stage.
