Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a soil disinfection machine G that is capable of working on a ridge and injecting a chemical solution toward the center of the ridge that is being formed.

Conventionally, two-ring disinfection machines use chemicals such as chloropicric acid to sterilize and disinfect the soil.When the machine turns around at the edge of a ridge, the powerful chemicals such as picric acid leak into the air or onto the soil surface. In order to prevent this, when the handle of the aircraft is pushed down and the towing vehicle body is tilted forward and backward during one-way movement, the drive of the pump that sends out the chemical solution is released and the spraying of the chemical solution from the nozzle is stopped. Some soil disinfection machines are known, but in this type of soil disinfection machine,
Even when the amount of soil is insufficient during ridge formation and the tip of the nozzle is exposed from the soil, the chemical solution is pumped out by the pump, causing problems such as some of the chemical solution being splashed onto the creator.

This invention has been proposed in view of the above-mentioned problems, and the purpose of this invention is to ensure safety for workers by stopping the sending action of the chemical solution when the tip of the nozzle is exposed from the soil. It is something.

For this reason, the present invention has taken the following technical measures.

That is, the chemical liquid is pumped between the pump (3) that pumps out the chemical liquid in the chemical liquid tank (4) mounted on the towing vehicle body (1), and the ridge raising device aυ arranged behind the vehicle body (1). A soil disinfection machine (G) equipped with a nozzle M that sprays water into the ground.
, the nozzle 0Q is pivoted to the back of a transmission case (8) of a rotary λ nozzle connected to the rear of the vehicle body (1) so as to be able to swing back and forth to reduce the resistance of the soil during ridge work. The soil disinfection machine is characterized in that it is configured so that the chemical solution is sent into the soil only when it is received.

Since this invention is configured as fiiJ 38, it has the following technical effects.

That is, during ridge-raising work, the towing vehicle body enters a recess, etc., and the attitude of the towing heavy body (1) changes to a forward-leaning position, causing the rotary to become deeper or shallower, and the soil being transferred to the ridge-erecting device 0) side changes. If the amount is insufficient, the chemical solution will be ejected into the soil, and the resistance of the soil applied to the tip of the nozzle θQ will decrease. Therefore, the nozzle 0 will tilt forward around its pivot point, causing the chemical solution to leak into the air or Ejection onto the soil surface is temporarily stopped.

Therefore, there is no problem of this chemical solution splashing onto the worker, or causing the chemical solution to flow out from the surface of the ridge into the grooves of the ridge and wasting the chemical solution. We were able to obtain an extremely efficient soil disinfection machine that could intensively inject this chemical solution.

In the illustrated example, (1) is a mobile agricultural machine as a towing vehicle body, and the base of this mobile agricultural machine (1) is equipped with a pump (3) that is rotationally driven by the rotation of drive wheels (2), and a pump that pumps chemical liquid. A chemical solution tank (4) is mounted thereon. Mobile agricultural machinery (1)
A rotary tillage device (5) is connected to the rear part of the mobile agricultural machine (
1) Side mission case (6) PT protruding from the side
The rotational force is transmitted to the input shaft (9) of the transmission case (8) on the rotary tillage device (5) side via the O-axis (not shown), belt (7), etc., and a shaft rack is installed at the bottom of the transmission case (8). The soil is tilled by giving rotation to the claw shaft (Ic). Also θ
υ is a ridge making device attached to the rear of this rotary tillage device (5), and this ridge making device OI) is used to press and shape the ridge sides with left and right side shaping plates (c) and to shape the ridge top. It consists of an upper shaping plate 03.

A supporting rod αυ is fixedly installed toward the front in the lateral center of the horizontal frame 04) that supports the ridge raising device aυ, and the upper end of the nozzle OQ for jetting and injecting the chemical solution into the soil is supported at the tip of this rod αυ. .

Figures 3 and 4 are enlarged views of the part that supports the nozzle αQ, and as shown in the figure, the tip of the support rod OQ has a through hole Q71 in the center, which is diagonally bored when viewed from the side. A cylindrical body OQ is provided, and a U-shaped rotating arm (4) that rotates about an axis 0 is attached to the cylindrical body (18) from the left and right sides.

A through hole 12]) is also provided in the center of the rotating arm (4), and a nozzle 0Q integrated with this arm H is connected to the chain shown in FIG.
When the cylinder body (+81 through hole 0η

Reverse +L valves (A), (A), and (4) are interposed in each of the valves, allowing the flow of the chemical solution only in the direction of the arrow, as shown in FIG.

(A) is a return spring interposed between the front part of the support rod (10) and the upper part of the nozzle 0Q. The nozzle α and the arm (4) are rotated by fMv as shown by the solid line (b) to cut off the communication between the three through holes Q71, t]) and (a).

In addition, in this embodiment, in order to support the nozzle αQ, the support rod θ is

It may also be directly supported.

In addition, if the nozzle Q[i is provided at the rear of the transmission case (8) as in this embodiment, the soil thrown backward by the rotation of the claw shaft may directly hit the nozzle OI, causing a malfunction. The spraying operation of the chemical solution is accurate because the front surface of the nozzle has advantages.
