Description

[Detailed description of the invention] This invention relates to an improvement of a trailer-type pesticide sprayer for spraying highly toxic, linked-action pesticides on agricultural land.

Generally, pesticides are sprayed manually or directly from a tiller using a siphon-type method using natural fall.
It is a pesticide to enable double cropping, liquid D, E, D,
Liquid B, chloropicrin, etc. are toxic and harmful to humans and animals if they come into contact with them, so first dig up the soil with a plow and stir it up.
It was necessary to infiltrate the pesticide into this and immediately cover it with soil.

The purpose of this invention is to provide a pesticide sprayer that simultaneously penetrates the pesticide by digging a hole as described above, and automatically covers the soil continuously. A trailer-shaped vehicle that can be towed by a tiller is equipped with a pesticide tank and a pump to suck it out at the front of the vehicle, and a soil-leveling vehicle is attached to the rear to cover and level the soil. Immediately before this, attach a plow to dig up the soil and a soil dropper to drop the soil, and open the pesticide spraying port connected to the discharge pipe of the pump on the back side of the plow blade, and at the same time, rotate the soil excavator and remove the soil. This is characterized in that it is associated with the drive of a pump.

The configuration of an embodiment of this invention will be described below based on the drawings. The frame 10 includes a rear frame 1 extending horizontally, a trifurcated front frame 2 that extends forward at an angle of inclination, and a rear frame 1 extending horizontally. A soil-raising wheel 4 is rotatably attached to the rear frame 1.

The earth-raising vehicle 4 consists of a wheel body 5 made of iron plate and four spokes 6, and on the wheel body 5 there are soil-raising blades 4 as shown in FIG.
a...4b...8 on both sides (a, b)
A total of 16 trees are planted one after the other.

The rotating shaft 7 of the revving wheel 4 is supported by the rear frame 1, and is provided with a crank arm 8 that rotates with the same rotation of the same shaft.

The arm 8 is the movement system 2 of the piston pump 15, which will be described later.
0, and the pump 15 is driven by the rotation of the coaxial shaft 7.

The front frame 2 is an inclined three-pronged pedestal, on which a tank 11 containing agricultural chemicals is mounted along with a band 12 and a pressing spring 13.
It is securely and removably fixed.

A piston pump 15 made of stainless steel is attached to the side of the front frame 2, and a piston shaft 16 is pin-coupled to the crank arm 8 of the upper revving wheel via a connecting rod 17.

A flexible tube 18 like a hose is connected to the suction port 15a of the piston pump 15, and a suction tube 19 provided at the tip of the intermediate tube 18 is formed so that it can be inserted into the chemical tank 11 and fixed therein. There is.

A flexible tube 21 like a hose is connected to the discharge port 15b of the pump 15, and a float-type glass flow meter 22 is provided in the middle of the tube 21 at a position easily visible to the operator.

A portion of the pipe 21 beyond the flow meter 22 extends along the blade 26, and a drain port 21a at the tip opens at the tip of the back of the blade.

In FIG. 2, a support plate 25 is provided near the boundary between the front frame 2 and the rear frame 1, and a blade 26 (see FIG. 1) is provided approximately at the center of the support plate 25, pointing downwards from the frame. 15-20c from the periphery of the top raising wheel 4
One piece is provided so as to extend downward.

Further, a soil dropping piece 27 is provided on the support plate 25 to project upward from approximately the center thereof toward the center of the wheel body 5 of the upper soil raising wheel 4 for dropping soil that has adhered to the soil raising blades. ing.

Since this invention is constructed as described above, when the connecting part 3 of this trailer type agricultural chemical sprayer is connected to the body of a tiller (not shown) and the tiller is operated, the blades 26
Cultivated land is created.

At the same time, the soil maker rotates, so this rotation drives the piston pump 15, and the pesticides in the chemical solution tank 11 are transferred to the suction pipe 19, the suction hose 18, the pump 15, the discharge hose 21. The drain port 21 passes through the flow meter 22 and the discharge hose 21.
It is discharged into the soil from a.

Thereafter, the soil lifted by the soil-raising vehicle 4 is scraped off by the soil-dropping piece 27, dropped onto the soil containing the chemical solution, and leveled by the wheel 5.

Therefore, when spraying the chemical solution, there is no danger that the chemical solution will come into contact with the skin of humans or animals during operation or even after being sprayed.

In addition, although the above-mentioned embodiment explained the case where there is one blade and one soil-raising wheel, it is of course possible to use a plurality of these.

As explained above, this invention uses a trailer-shaped spreader, so it can be attached to the rear of the tiller and spread without the need for manpower.

In addition, since the pump is a piston pump and the drive of the pump is related to the rotation of the soil excavator, it is useful as a pesticide sprayer that is mainly lightweight and does not require a separate drive source for the pump.
