Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Field of Industrial Application This invention provides for
A transplant with a fertilizer application device, which is equipped with a fertilization device consisting of a hopper that accommodates fertilizer, a feeding device that feeds out the fertilizer from this hopper, and a transfer chamber that transfers the fed fertilizer to the groove of a trencher that creates grooves on the soil surface. It's about machines.

Prior Art As disclosed in Japanese Utility Model Application Publication No. 59-29123, in a transplanter equipped with a fertilizer applicator, a ratchet mechanism is used to transmit the rotating shaft of the fertilizer delivery device from the drive shaft of the transplanter. It was conducted by the crank, and from the output shaft of this ratchet mechanism via a flexible shaft.

Problems to be Solved by the Invention In the conventional technology, the structure is complicated, and the rotating shaft of the delivery roller is not rotated continuously, so there is a problem that the fertilizer cannot be delivered smoothly.This problem is solved. In order to do this, we tried a configuration in which a V-pulley was attached to the drive shaft of the transplanter and a belt was wound between the V-pulley and the V-pulley provided on the rotating shaft of the delivery roller to transmit power. However, the drive shaft of the transplanting tool is close to the surface of the topsoil of the paddy field, and even if it is located above the II ground rough float, if a V pulley or sprocket is installed on this drive shaft, these V pulleys will be damaged during the transplant operation. Muddy water adheres to the rotor and sprocket, and this wraps around and attaches to the V pulley and sprocket of the rotating shaft of the fertilizer dispensing roller via an endless band (belt, chain). There was a drawback that it penetrated into the roller part and could not be smoothly fed out.

The feeding device 22 has a feeding roll (not shown) mounted in its case body, and this rotating shaft 25 connects the spindles of the feeding rolls of each feeding device 22 so as to transmit power all at once. There is.

Reference numeral 26 denotes a V-boot as a drive shaft, which is indirectly attached to the drive shaft 15 via the rotating case 11. That is, it is fixed to the outer surface of the rotating case 11 with bolts, and is configured such that the outer end side of the bearing protrusion metal 9a of the drive shaft is covered by the V-pulley 26.

Reference numerals 27 and 28 designate double V pulleys as winding rings, which are rotatably provided on an intermediate shaft 30 attached to the support frame 17 via a bracket 29.

This cylindrical body 36 is connected to a funnel 37 that is connected between the feeding device 22 and the transfer chamber 24 located at the lower part thereof through a blowing pipe 38, so that the fed fertilizer is air-transported to the furrowing device 23. It is composed of

Note that the blower 34 is conveniently an electric type with an integrated motor.

Further, to explain the machine frame structure of another embodiment with reference to FIGS. 5 and 6, a cylinder 36a is fixed to a support frame 17a, and a feeding device 22 is attached to this cylinder 36a via a bracket 39. The configuration is simplified. In the case of this embodiment, the blowing side of the blower 34 is connected to one side of the cylindrical body 36a.

According to the configuration shown above, seedlings are placed on the seedling storage table 1o, granular fertilizer is placed in the hopper 21, and the transplanting device 8 side is lowered by the lifting link device 7, so that the soil leveling float 14 is brought into contact with the surface of the topsoil of the paddy field. Then, the transplant device 8 is attached to the towing vehicle body 1.
Rotate each rotating part while pulling the side.

Then, the rotation case 11 rotates due to the rotation of the drive shaft 15, and the transplant case 12.12 rotates while swinging, and its transplant claws draw a transplant trajectory (a) from the seedling storage table 1o that moves laterally from side to side. The seedlings are divided and transplanted one after another onto the topsoil leveled by a leveling float 14.

On the other hand, the rotation of the drive shaft 15 rotates the ■ pulley 26, and from this, the two pulleys 27 and 28 of the intermediate shaft 30 are transmitted and rotated by the V belt 32, and from this V pulley 28, the rotating shaft 2
5 is rotated via a V-belt 33 and a V-pulley 31.

Therefore, the feed roll of the feed device 22 rotates, and the fertilizer in the hopper 21 is smoothly fed out by the continuously rotating feed roll and discharged into the funnel 37. Then, the air inside the cylinder 36 that is constantly blown by the blower 34 is blown into the funnel 37 by the blower pipe 38, and the fertilizer is reliably transferred to the transfer pipe 24.
and is discharged into the groove created by the groove creator 23.

In this way, fertilizer will be applied at the same time as transplanting.

During such work, the power of the feeding device 22 is transmitted from the rotating drive shaft 15 of the implanter 13. Since this is carried out using the belts 32 and 33, even if muddy water, weeds, etc. that are splashed or rolled up by the transplanting tool 13 or the rotating case 11 are lifted upward by the V belt 32, the V pulley 27 of the intermediate shaft 3o The rotating shaft 25 is not contaminated because it is unlikely to be lifted from now on.

Therefore, although the transmission structure is simple, one rotation shaft 25
is kept clean, muddy water does not enter the inside of the feeding device 22, and the fertilizer can be fed out reliably.

Note that the air pressure inside the cylinder 36 is approximately uniform, so that air is blown out evenly to each of the air pipes 38, 38, etc. to ensure that the fertilizer is conveyed. It plays a role in the frame structure of the fertilizer application device 16 and can realize a strong frame structure.
