Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a ground working machine, and more particularly to a cleaning device for a vegetable residue collecting machine.

[0002]

2. Description of the Related Art In recent years, continuous cropping problems of the same vegetable have become a serious problem in vegetable producing areas. For example, when leaf vegetables such as cabbage and Chinese cabbage are continuously grown, soil-borne diseases such as root-knot disease often occur.

Therefore, in fields where vegetables are continuously grown, chemicals are sprayed to control soil diseases.

[0004]

Conventionally, as a measure against soil-borne diseases of vegetables, the chemicals have been sprayed as described above, but the damages may become more severe each year and the chemicals may be polluted. As a countermeasure against soil diseases of vegetables, other methods include collecting residues of vegetables such as rhizomes and outer leaves left on the field at the time of vegetable harvesting with a ground work machine, etc., and transporting the collected vegetable residues to the outside of the field. is there. At that time, the vegetable residue may contain soil pathogens, and if the soil pathogens adhere to the ground work machine, they may be transmitted to other fields.

Therefore, there is a technical problem to be solved in order to remove the soil pathogens easily by cleaning the ground work machine that collects the vegetable residue to another field at any time when moving to another field. The present invention aims to solve this problem.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above-mentioned object.

A car wash pump is installed, the tank and the car wash pump are connected by a suction hose, and further a discharge hose is connected to the car wash pump to provide a cleaning device for a ground work machine provided with a nozzle at its tip. is there.

[0007]

[Function] The tank fixed to the hitch frame is filled with cleaning water such as water or chemical liquid. When the car wash pump is driven, the cleaning water in the tank is pumped up through the suction hose and the nozzle from the discharge hose. Sent to. The wash water is squeezed as it passes through the nozzle and is injected at a high pressure.

[0008] By washing the parts of the ground work machine with the cleaning water sprayed from the nozzle, the dirt and pathogens attached to the ground work machine are removed.

Wear 3.

A pipe 60 is provided below the mast 42.
And the gauge wheels 61, 61 are pivotally attached to the pipe 60. Incidentally, reference numeral 62 is a PTO input shaft, which is the P of the tractor.
The TO output is transmitted from the PTO input shaft 62 through the universal joint 63 to the transmission mechanism section 64.

Next, the power transmission system of the vegetable residue collector 11 will be described with reference to FIGS. 4 and 5. The universal joint 67 connects the PTO output shaft 66 of the tractor 65 and the PTO input shaft 62 of the vegetable residue collector 11.
The PTO output of the tractor 65 is the universal joint 6
7 to the PTO input shaft 62, and further via the universal joint 63 to the gearbox input shaft 68.
Is transmitted to

The power transmitted to the gear box input shaft 68 is transmitted to the bevel gears 70 and 7 in the gear box 69.
It is output to the first output shaft 72 by the meshing of 1 and is output to the second output shaft 75 by the meshing of the spur gears 73 and 74. The power of the first output shaft 72 is transmitted to the pulley 77 and the sprocket 78 via the clutch 76, and the rotation of the pulley 77 is transmitted to the rear pulley 80 by the belt 79. The above-mentioned conveyor sprockets 16 and 16 are fitted coaxially with the pulley 80.
The conveyor sprockets 16 and 16 rotate in the same direction as 0. Therefore, the conveyor sprockets 15, 15 and 16,
The chains 17, 17 wound between 16 and 16 rotate, and the bar conveyor 19 is driven.

The rotation of the sprocket 78 is transmitted to the sprocket 82 via the chain 81. A pulley 83 is fitted coaxially with the sprocket 82, a pulley 85 on the rotary side rotates via a belt 84, and
The meshing of the spur gears 86, 87 causes the rotary 13 to rotate.

On the other hand, pulleys 88 and 89 are fitted on the second output shaft 75, and the rotation of the pulley 88 is transmitted to the pulley 91 via the belt 90 to drive the hydraulic pump 92. The rotation of the pulley 89 is caused by the belt 93.
Is transmitted to the pulley 94 via the car wash pump 4 described above.
7 is driven. A belt tension clutch 95 is provided on the belt 93, and by tensioning or loosening the belt 93, driving of the car wash pump 47 is turned on / off. During the work of collecting the vegetable residue, the drive of the car wash pump 47 is turned off by the belt tension clutch 95.

Although the car wash pump 47 is a power pump, an electric car wash pump may be used. In that case, instead of the pulleys 89, 94, the belt 93, and the belt tension clutch 95, an electric cable is wired from a battery (not shown), and a car wash pump is turned on / off by a switch.

When the vegetable residue collector 11 is pulled by the tractor 65 and travels in the field, the vegetable residues are first crushed by the rotary 13. The crushed vegetable residue is picked up at the front part of the bar conveyor 19, and while being carried to the upper rear part by the bar conveyor 19, the dirt and mud adhering to the vegetable residue is sieved off. Then, at the rear end portion of the bar conveyor 19, the transfer pieces 22, 22, ... Are largely reversed, and the vegetable residue is thrown to the bucket 36 at the rear.

As described above, the vegetable residue is continuously stored in the bucket 36, and when the vegetable residue is filled in the bucket 36, the bucket 36 is brought closer to the truck bed, and the lift cylinder 32 and the dump cylinder 39 are provided. The bucket 36 is turned upside down by the extension of the
Transfer the vegetable residue from the above to the loading platform of the truck. The bucket 36, which has been emptied by adding the vegetable residue, becomes horizontal again and descends due to the contraction of the lift cylinder 32 and the dump cylinder 39.

By repeating the above operation, the vegetable residues in the field are automatically collected and sequentially transferred to the truck without human touch. After the vegetable residue collecting work is completed, the car wash pump 47 is operated to wash the vegetable residue collecting machine 11. FIG. 6 shows a main part of the cleaning device, and an impeller 55 is attached to the rotary shaft 54 of the car wash pump 47. The tank 52 is filled with cleaning water 56 such as water or a chemical solution, and a strainer 57 is attached to the tip of the suction hose 50 inserted into the tank 52.

Thus, the belt tension clutch 9
5 turns on the drive of the car wash pump 47, and the impeller 5
When 5 is rotated, the washing water 56 in the tank 52 is filtered by the strainer 57, then pumped up from the suction hose 50, and sent from the discharge hose 51 to the nozzle 53. The cleaning water 56 is squeezed when passing through the nozzle 53 and is injected at a high pressure.

Therefore, if the operator holds the nozzle 53 and injects the washing water 56 to various places of the vegetable residue collector 11, soil pathogens, mud and the like attached to the vegetable residue collector 11 will have high pressure. It is washed away with wash water and removed.
The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.

[0028]

As described in detail in the above-mentioned one embodiment, the present invention is provided with a car wash pump and a tank on the ground working machine so that the car wash pump can be driven at any place. Therefore, the soil mud and soil pathogens attached to the ground work machine can be easily removed with high-pressure washing water at any time.

Thus, the ground work machine can be cleaned simply and quickly, and maintenance management becomes easy.
