Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a spraying device suitable for use in spraying chemical solutions to crops.

Conventional technology When disinfecting tall crops such as tomatoes and yams, a large number of spray nozzles are fixedly attached to a metal pharmaceutical liquid conduit near the tip of a self-propelled vehicle with an engine loaded with a chemical tank and a chemical liquid pressure pump. A common method is to set up spray poles attached at intervals of 1,000 yen, and a worker drives a self-propelled vehicle to move between the furrows and spray the chemical solution from side to side. However, in this case, the worker enters the mist of the chemical solution spraying from the spray rod and floating around, and no matter how careful he or she is, there is a risk of inhalation of the chemical solution or contact with the skin, mucous membranes, etc. It was not possible to prevent adhesion.

Purpose of the invention The present invention was developed in response to these circumstances, and is a spray device that can prevent workers from inhaling highly toxic pesticides and preventing pesticides from adhering to their skin or clothing. The purpose is to provide the following.

Structure of the invention The gist of the invention is to provide a vehicle equipped with a chemical liquid tank and a chemical liquid pressure pump connected to the liquid chemical tank, and to connect the chemical liquid pressure pump to a flexible chemical liquid conduit such as a hose, and a conduit opening/closing valve such as an on-off valve. consisting of one or more spray rods connected together and a backpack for holding the spray rods,
A spraying device is characterized in that it can spray a chemical solution from behind a worker laterally or backwards with respect to the direction of movement of the worker.

Hereinafter, a detailed explanation will be given based on one embodiment.

As shown in FIG. 1, the present spraying device includes a self-propelled vehicle 20 equipped with a chemical liquid tank 22 and a chemical liquid pressure pump 21, and a rubber hose 2 attached to the chemical liquid pressure pump 21.
4. Spray rods 1, 1 connected via opening/closing handle 6
and a backpack 10 for holding the spray rods 1, 1.

The chemical liquid pressure pump 21 is connected to the vehicle driving engine 2.
It is driven by an output shaft (not shown) of 3 via a belt (not shown) to forcefully feed the chemical liquid to the hose 24, and 26 has one end inserted into the chemical liquid tank 22 and the other end inserted into the chemical liquid tank 22. This is a hose connected to the suction port (not shown) of the chemical liquid pressure pump 21. On the other hand, the backpack 10 is made up of a rectangular frame made of metal pipes with shoulder belts 11 and 12 attached, and supports 13 and 1 on the left and right sides of the rectangular frame.
A spray rod attachment rod 17 made of a square pipe is fixedly attached to arcuate rods 15 and 16 provided astride the spray rods 4. The spray rod attachment rod 17 has sliding rings 5, 5 having a fixing thumbscrew 5a (Fig. 3) on one side and mounting portions 5b, 5b for the spray rod support arms 4, 4 on the left and right sides. , is slidably fitted on the outside,
The mounting portion 5 of the arm of this sliding ring 5, 5
One ends of spray rod support arms 4, 4 are rotatably attached to b, 5b, respectively, and the other ends of the support arms are pivotally attached to the spray rods 1, 1 via attachment members 3, 3. As a result, the spray rods 1, 1 are arranged symmetrically in a wing-like manner on the left and right sides of the spray rod attachment rod 17. The spray rods 1, 1 consist of a metal liquid conduit whose upper and lower sides are closed, and spray nozzles 2, 2, . The provided opening/closing pots 6 and 6 are connected to each other by a chemical liquid conduit 7, and the other end of the hose 24 connected to the discharge side of the chemical liquid pressure pump is connected to the chemical liquid conduit 7. It is what it is.

The spray device according to the above embodiment adjusts the direction of the nozzles 2, 2, and screws the sliding rings 5, 5 onto the thumbscrew 5.
a, 5a and move it up and down along the spray rod attachment rod 17 to adjust the mutual distance, inclination, height, etc. between the spray rods 1, 1 according to the spraying target, and then tighten the thumbscrews. Tighten and fix 5a and 5a. Next, the self-propelled vehicle 20 is carried on the back using the shoulder belts 11 and 12, as shown in FIG.
When the worker moves through the furrows, the chemical solution is sprayed to the left and right of the worker.

In the above embodiment, the distance between the spray rods is adjusted by the sliding rings 5, 5 and the support arms 4, 4. Hollow pipe 30 to the rod mounting rod 17
is fixed, and the spray rod support arms 31, 31 are slidably fitted into the hollow pipe 30, and the spray rods 1', 1' are attached to one end of the holding arms 31, 31, and rotated around the axis. Possibly, via the fittings 32, 32,
It may be attached.

Effects According to this invention, not only can accidents caused by highly toxic pesticides be prevented, but each time a chemical solution is sprayed, pesticides enter the body little by little, and can be used to prevent chronic drug addiction. In addition, the danger is extremely reduced and the work can be carried out with peace of mind.
