And a fertilizer application device having a hopper 21 for storing fertilizer and a feeding device 22 connected to a lower portion of the hopper 21 to feed the fertilizer from the hopper 21 via the brackets 20 on the horizontal frame 18. 16 is attached. In this fertilizer application device 16, the fertilizer fed by the feeding device 22 receives the wind from the blower 34, moves in the transfer pipe 24, and is transported to the formation groove of the groove generator 23 for forming a groove on the soil surface. It has become so. The case main body of the feeding device 22 is fixed to the bracket 20, and the hopper 21 is provided so as to be fitted into the upper frame 19 of the above-mentioned type. The upper end of 19 is located on the upper rear end side of the hopper-21. Therefore, when the fertilizer is supplied to the hopper 21, it can be carried out while supporting a bag or the like containing the fertilizer in a portion of the upper frame 19 located in the vicinity of the hopper 21, so that an excessive load is applied to the hopper 21. Do not apply
The fertilizer can be supplied to the hopper-21 with less labor. Further, when viewed from the back, the hopper 21 has a bottom-shaped bottom, and has a structure capable of distributing and supplying fertilizer to the left and right feeding devices 22, 22. Feeding device 2
2 is provided with a delivery roll (not shown) in the case body, and this rotating shaft 25 is connected to the support shafts of the delivery rolls of the respective delivery devices 22 to be transmitted at once. I can do it. Reference numeral 26 denotes a V-pulley as a driving wheel, which is indirectly mounted on the driving shaft 15 via a rotating case 11. That is, it is fixed to the outer surface of the rotating case 11 with bolts, and the outer end side of the bearing projection metal 9a of the drive shaft is covered with the V-pulley 26. Reference numerals 27 and 28 denote double V pulleys as wrapping rings.

Reference numerals 32 and 33 denote V-belts as endless belts. Numeral 34 denotes a blower, which is mounted on a tank 36 formed of a horizontally long, closed cylindrical body mounted via brackets 35, 35 on the back side of the above-mentioned upper frame 19, and blows out from the blower 34. The mouth communicates with the inside of the tank 36.
The tank 36 and a funnel 37 connected between the feeding device 22 and the lower transfer pipe 24 are connected by a blower pipe 38, and the fed fertilizer is pneumatically conveyed to the groove generator 23. It is configured as follows. This tank 36 plays a part in the frame configuration of the fertilizer application device 16 and has a strong frame.
It embodies the system configuration. It is convenient for the blower 34 to be of an electric type with an integrated motor. 5 and 6, the frame structure of another embodiment will be described.
A tank 36a is fixed to 7a, and the feeding device 22 is attached to the tank 36a via a bracket 39 to simplify the configuration. That is, the tank 36a itself is the hopper-21.
And since it is the support frame of the feeding device 22, the weight can be further reduced. In this embodiment, the blowing side of the blower 34 is connected to one side of the tank 36a. According to the configuration of the above example, seedlings are placed on the seedling storage table 10, granular fertilizer is put into the hopper 21, and the transplanting device 8 is lowered by the elevating link device 7. In contact with the topsoil surface of
Rotate each rotating part while pulling the transplanting device 8 side. Then, the rotation case 11 is rotated by the rotation of the drive shaft 15, and the transplant cases 12, 12 are rotated while oscillating, so that the transplant nails draw a transplant locus (a) and move laterally to the left and right. The seedlings are divided from the accommodation table 10 and transplanted one after another on the topsoil surface which is leveled by the leveling float 14. On the other hand, the V-pulley 26 is rotated by the rotation of the drive shaft 15, and the V-pulley 27,
28 is driven and rotated by a V-belt 32.
, The rotation shaft 25 is rotated via the V belt 33 and the V pulley 31. Therefore, the feeding roll of the feeding device 22 rotates, and the fertilizer in the hopper 21 is smoothly fed by the continuously rotating feeding roll, and is discharged into the funnel 37. Then, the air in the tank 36 constantly blown by the blower 34 is blown into the funnel 37 by the blower tube 38, and the fertilizer is reliably discharged through the transfer pipe 24 into the groove formed by the groove generator 23. The inside of the tank 36 has a substantially uniform air pressure, from which air is blown out uniformly to each of the ventilation pipes 38 to reliably transport the fertilizer. In this way, fertilization will occur at the same time as transplantation. During such operation, the transmission of the feeding device 22 is performed by the rotating drive shaft 15 of the implanting tool 13, but at this time, via the V pulleys 27 and 28 having different winding lines provided on the intermediate shaft 30. V
Since the operation is performed by the belts 32 and 33, even if muddy soil or weeds that are splashed or rolled up by the implanting tool 13 or the rotating case 11 are lifted upward by the V belt 32, the V of the intermediate shaft 30 is increased. It only stops at the pulley 27 and it is unlikely to be lifted from now on, so that the rotating shaft 25 is not contaminated. Therefore, while the transmission structure is simple, the rotating shaft 25 is kept clean, and muddy soil does not enter the inside of the feeding device 22, so that the fertilizer can be fed without fail. Further, a tank 36 formed long in the lateral direction of the machine body is fixedly provided on the machine body, and the fertilizer fed from the feeder 22 by the compressed air sent from the tank 36 is transferred through the transfer pipe 24, and Since the tank 36 is a constituent member of the support frame of the hopper 21 and the feeding device 22, the tank 3 has a three-dimensional shape in which the pressurized air is accumulated inside and is long in the lateral direction of the body.
6, a compact and lightweight transplanter with a fertilizer can be obtained, and good seedling planting and fertilizing operations can be performed. In the transplanter with the fertilizer application device, the portion extending in the lateral direction of the frame 19 is located vertically above and below the upper end of the plurality of hoppers 21 and the plurality of hoppers 2
1 so that the fertilizer is supplied to each of the hoppers 21 arranged side by side, a bag or the like containing the fertilizer is provided in the portion of the frame 19 extending in the horizontal direction. It can be done while supporting it, so the hopper
The fertilizer can be supplied to each hopper 21 without applying an excessive load to the hopper 21 and with less labor. Moreover, since the frame 19 is of a zigzag type and is fixed to the horizontal frame 18 extending along the left and right directions on which a plurality of feeding devices 22 are mounted, the frame structure supporting the fertilizer application device is a horizontal frame. The frame 18 and the frame 19 form a strong frame structure, so that the frame 19 becomes one of the strength members of the frame structure that supports the fertilizer application device, resulting in a rational configuration.
