Description

[Detailed description of the invention] [Industrial application field] This invention is a push-pull sprayer for spraying pesticides, herbicides, fertilizers, etc., which is mounted on a manual trolley to enable easy spraying work. In the type power spreader,
A push type that prevents the power spreader from falling over due to being pulled to the side by the spray hose during spraying work, and allows the operator to move the sprayer easily without applying unnecessary force. This relates to a power spreader.

[Conventional technology]

Conventionally, power spreaders with a pesticide tank, small engine, and fan are carried on the back of workers, but the machine itself is quite heavy, and it also carries fertilizers, pesticides, etc. Because it is used to store water, the weight increases considerably, and the spraying work is extremely troublesome and hard work for farmers.

Therefore, it has been attempted to mount a power spreader on a simple truck, but this method has various drawbacks such as ease of operation.

[The problem that the idea aims to solve]

The present invention solves these drawbacks, and allows easy spreading work by mounting the power spreader on a push-type trolley, and also allows the power spreader to be pulled laterally by the spraying hose during hose spraying work. A technical challenge is to provide a push-type power spreader that can be easily pushed without causing the machine to fall over or requiring unnecessary force on the operator.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

A power spreader 2 is mounted on a truck frame 1 with a push handle 9 provided at the rear, and a jet pipe support fitting 4 that supports a jet pipe 3 of the power spreader 2 is attached to the push handle 9.
The distal end portion 13 of the support band 5 attached between the operator who pushes the truck frame 1 using the pushing handle 9 and the dispersion hose 17 connected to the jet pipe is connected to the base of the dispersion hose 17. The present invention relates to a push-type power spreader characterized in that the base of the support band 5 is provided with an attachment part that is attached to the body of a worker.

[Effect]

The jet tube 3 is supported by the push handle 9 by the jet tube support fitting 4, and the spray hose 17 is held on the body of the operator by the support handle 5.

〔Example〕

A unicycle 6 is provided at the center of the front part of the bogie frame 1, and a grounding roller 7 wider than the width of the unicycle 6 is rotatably provided in a direction perpendicular to the forward direction of the rear part. (In order to prevent the bogie frame 1 itself from swinging, the grounding roller 7 is connected to the bogie frame 1.
It is preferable to install it so that it can swing freely against. ) The width of 7 ground rollers is approximately the same as the width of 1 width of the bogie frame.
A mud-repelling member 8 made of rubber or sponge that also serves as a cushion is wrapped around the surface.

A push handle 9 is provided diagonally on both sides of the rear part of the truck frame 1. Blower tube 3
A blower tube support fitting 4 is provided to support and fix the head tube at a variable angle.

The support handle 5 consists of a shoulder handle 5a and a waist band 5b, and the support band 5 is provided with a connecting band 13 that is detachably connected to a stopper 12 attached to a spray hose 17 connected to the jet tube 3. There is.

The power spreader 2 mounted on the trolley frame 1 is a backpack type, and 14 is an engine, 15 is a pesticide tank, 16 is a fan, 17 is a spray hose, 18 is a joint part, and 19 is a discharge amount adjustment lever. .

This discharge amount adjustment lever 19 is extended near the pushing handle so that it can be operated when pushing.

[Effect of idea]

As mentioned above, the present invention has the power spreader 2 mounted on the trolley frame 1, so that if the operator pushes the machine and moves it forward on the ridge, the heavy power spreader 2 can be moved like a conventional one. You can do spraying work without having to carry it on your back.

In this case, when performing spraying work by connecting the spray head pipes 3 of the power spreader 2, fix the jet pipes 3 to the trolley frame 1 at a desired angle via the support fittings 4, and then move the machine on the ridge. By pushing the sprayer forward, you can easily perform ridge spraying work without having to carry the heavy power spreader 2 on your back like in the conventional case.

In addition, when performing hose spraying work by connecting the spraying hose 17 to the tip of the jet pipe 3, the worker who holds the tip of the spraying hose 17 and the worker who pushes the machine are required to work in the fields. By moving forward along the ridges on both sides, the user can easily perform hose spraying work by simply pushing the push handle 2 without having to carry the heavy power spreader 2 on his/her back as in the conventional case.

During this above-mentioned hose spraying work, the spraying hose 17
This causes the machine to tend to be pulled to the side, causing the machine to fall, and the operator having to use force to hold the push handle 9 of the machine to prevent it from falling, which is very tiring. , there was a drawback that prevented progress.

In this respect, the present invention sprays the tip portion 13 of the support band 5 attached between the operator who pushes the truck frame 1 using the push handle 9 and the spray hose 17 connected to the jet pipe 3. Since an attachment part is attached to the base of the hose 17 and attached to the body of the worker at the base of the support band 5, the squirt tube 3 is supported on the machine body by the squirt tube support fitting 4, and the support band 5 is attached to the body of the worker. Since the band 5 prevents the spray hose 17 from swinging, both the jet tube support fitting 4 and the support band 5 reliably prevent the spray hose 17 from being pulled laterally, and this state is maintained. The operator does not have to use more force than necessary to hold the push handle, which reduces fatigue, and the operator can easily move the product forward without resistance, making it easier to perform spraying work. This has practical effects.
