Description

Agricultural chemicals spreader Of Cart-type}

The present invention relates to a paddle-type drug solution dispenser, and more particularly, to a paddle-shaped drug solution dispenser capable of easily spraying a drug solution in a tank by spraying the drug solution in the tank with only the rotation of the wheel without external power, And a spraying range including a spraying height, an angle and a spraying distance.

Generally, crops growing on furrows or crops growing on tunnels of greenhouses are sprayed with various pesticides (hereinafter referred to as pesticides, nutrients, etc.) for the prevention of insect pests and growth.

In the case of spraying a chemical solution such as pesticide in a corrugated or corrugated planted land, the spraying hose reaching tens of meters causes the auxiliary worker to pull or pull the spraying hose, which makes it difficult to spray the chemical solution. In addition, Due to the aging of the agriculture population in rural areas, there is a limit to being able to get back on it, and it was impossible to spread a large area even for young people.

In order to solve such a problem, in the prior art, an agrochemical sprayer for spraying a chemical solution by using the force of an engine mounted like a vehicle or a cultivator has been proposed.

However, since the apparatus for spraying the chemical liquid by receiving the separate power from the engine as described above is not used frequently, the gasoline introduced into the inside of the machine during long-term use may block the capillary, And there is a problem of pulling the starter key and discharging harmful harmful substances to the human body and the crops because the engine must be turned on and off repeatedly even when spraying the pesticide.

As an apparatus for solving this problem, as disclosed in Korean Patent Laid-Open Publication No. 10-2009-0096390 'rechargeable single-handed pesticide sprayer', in the prior art, an agrochemical sprayer for spraying a chemical solution using the power of a motor .

By using rechargeable battery and motor, it is possible to eliminate the residue and reduce the occurrence of pollution pollution. However, since the separate power device such as battery and motor must be provided, the weight of the chemical solution distributor itself is inevitably large. And there is a problem that it is difficult to use easily due to aging population.

In addition, it is necessary to check whether or not the battery is used from time to time to charge the battery, and there is a problem that frequent repairs and maintenance checks must be performed according to the use of the motor.

Accordingly, there is a need to develop a chemical liquid spreader which is easy to use without using any external power, and which has a simple operation structure and is easy to repair and maintain.

On the other hand, the conventional pesticide sprayer is practically difficult to spray the chemical solution on various crops because the modified spray angle and the spraying distance adjustment structure capable of adjusting various angles, heights and lengths of the spray zone are not provided.

In order to prevent such a problem, a power sprayer capable of adjusting the height and width of a spray nozzle has been proposed in the past, which is provided with a power unit and a spray liquid injection box on a movable body, And the second body and the third body are formed so as to be adjustable in height using a rack and a pinion, and the injection nozzle base having the injection nozzle is rotatable using a clamp.

However, the power sprayer according to the present invention is a heavy object equipped with a power unit and a spray liquid spraying box on the body and has a disadvantage in that it is difficult to move. Therefore, it can not be used in a place such as a slope, .

In addition, the above-mentioned invention has disadvantages in that the initial cost is high because the conventional power sprayer can not be used, and there is a problem that it is difficult to store in a space with a narrow space.
