Description

[Detailed explanation of the idea] The present invention relates to a riding-type power pest control machine.

Conventional powered pest control machines spray chemicals onto crops from above, but
It was difficult for the chemical solution to reach the underside of the leaves and the inside of the thick leaves, so there was room for improvement in terms of pest control.

The purpose of this invention is to make it possible to effectively spray a chemical solution on the underside of leaves and the inside of thick leaves by simple modification. A power sprayer and a blower for spraying are mounted on the passenger car body, and a nozzle group consisting of a plurality of the nozzles arranged at appropriate intervals in the vertical direction is placed at intervals in the left-right direction of the car body and sprayed on the crops. At the same time, the air blower is connected to the rear part of the vehicle body so that the chemical solution is sprayed laterally. It is characterized by being placed near the nozzle group.

That is, by spraying the chemical solution from the sides of the crop, it is possible to spray the chemical solution not only on the upper surface but also on the underside of the crop's leaves, and furthermore, the chemical solution can be sprayed on the leaves of the crop by blowing air. Since this is done while shaking the leaves, gaps are created between the leaves, and the gaps are also shaken, allowing the chemical solution to be sprayed through the gaps to the inside of the thick leaves. , and the fact that the chemical solution spreads inside the leaf means that the chemical solution can be effectively sprayed on the underside of the leaf, and the chemical solution can be spread on the leaves that are agitated by the blowing air. Compared to spraying the chemical solution on the leaves that are stationary, the chemical solution can be applied evenly and better, and overall, it is as simple as shaking the crop and spraying the chemical solution from the sides. With significant improvements, it has become possible to effectively spray chemical solutions to the underside of crop leaves and the inside of thick leaves.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows a riding-type power extermination machine, in which 1 is a passenger vehicle body, which is equipped with a link mechanism 2 that can be raised and lowered on the front side, and an engine 4 covered with a bonnet 3 on the rear side. .

The link mechanism 2 is attached with an L-shaped frame 5 when viewed from the side, and the frame 5 includes a pair of left and right U-shaped stands 6, 6 that can be folded inward. , a bar stand 7, and a pedestal 8 are provided, and a chemical liquid storage tank 9 is mounted on the frame 5, and a power sprayer 10 for pressure-feeding the chemical liquid in the tank 9 is mounted on a PTO shaft 22. They are connected and attached to the pedestal 8. 11 is a hose connecting the tank 9 and the power sprayer 10.

Reference numeral 12 denotes a hose for pressure-feeding the chemical liquid from the power sprayer 10, and there are multiple hoses (three in the figure) downstream of the valve 13.
The hoses 14 are connected to each other, and each of the hoses 14 is provided with a valve 15.

Reference numeral 16 denotes a bracket extending rearward from both sides of the bonnet 3, and a support member 17 rotatable around the left and right horizontal axes is attached to the rear end side. This support member 17 is equipped with holders 18, which can be freely changed and fixed in position in the left and right direction, at the middle of the left and right sides and on both sides of the support member 17.
A holding member 19, which can swing and be fixed freely around the front and rear axes, is connected to each of the holding members 19 in a hanging manner.

20... is a nozzle group held by the holding member 19, which comprises a plurality of nozzles a... provided at appropriate intervals in the vertical direction of the pipe 21 connected to the hose 14; Each of a... is configured such that the direction of spraying the chemical liquid can be swung and fixed around the front-rear axis.

By changing the lateral position of the holder 18, the nozzle group 20 can be positioned between adjacent crops, and can be positioned laterally to the crop. The chemical solution can be sprayed, and by adjusting the direction of spraying the chemical solution with the nozzle a..., the chemical solution can be adjusted upward or downward, and the nozzle a... located at a higher position than the crop can spray the chemical solution onto the crop. The chemical solution can also be sprayed from above. and,
By operating the valve 13 in the operating section 26, the chemical liquid can be sprayed and stopped, and by operating the three valves 15, the nozzle group 20 to which the chemical liquid should be sprayed can be selected.

To attach the nozzle group 20 to the holding member 19, the holding tool 2 is slidably attached to the holding member 19.
3 and 24, and the upper holder 23 of them can be fixed in position by a fastener 25,
The pipe 21 is attached across the upper and lower holders 23 and 24, so that the spray range of the chemical solution by the nozzles a can be changed up and down.

An arm 27 is connected to the support member 17, and a lever 28 that can be fixed in two positions, front and back, is provided near the driving section 26, and the lever 28 and the arm 27 are connected by an interlocking mechanism 29. By operating the lever 28, the nozzle group 20
... is placed between adjacent crops, and the lower end of the nozzle group 20 is directed toward the rear of the vehicle so that the nozzle group 20 does not push down the crops when the vehicle turns. It can be switched to a horizontal position where it is lifted upwards.

30 is a blower mounted on the bonnet 3,
Engine 31 and blower 3 driven by it
a blower pipe 3 connected to the blower 32;
A header 34 is connected to the header 3, and the header 34 is connected to a total of four air outlets 35 for blowing air downward at two locations on both left and right ends and two locations in the middle of the left and right sides of the header 34, The crops to which the chemical liquid is to be sprayed can be agitated by blowing air from the air blowing ports 35.

In addition, as shown in FIG. 4, the ventilation port 35 may be bifurcated so that the air supply direction is directed to the lateral side of the crops, or as shown in FIG. Alternatively, the header 34 can be expanded and contracted as well as fixed, and each of the ventilation ports 35 can be changed and fixed in its position in the left and right directions, so that the positions of the ventilation ports 35 can be changed and set according to the adjacent dimensions of the adjacent crops.

Furthermore, the same number of air outlets 35 and nozzle groups 20 may be arranged.
