The present invention relates to an improvement of a pesticide spreader which allows for a smooth spreading operation while freely moving between crops.

Conventionally, farmers who grow peppers and cucumbers spray pesticides (pesticides, nutrients, etc.) to prevent pests of crops, and when a worker directly sprays crops using a manpower spreader, they grow a small amount of crops. Although it can be usefully used by farmers, it is impossible to use a manpower sprayer when cultivating a large amount of crops. Therefore, a power sprayer is mainly used to spray sprayed liquid from a power unit.

In this case, the motorized spraying device allows the worker to directly spray the crops with the sprayer or the spraying device having a plurality of spray nozzles while the worker is towed and spray the spraying liquid onto the crops.

In the former case, the operator has the advantage of spraying the spray evenly on the crop, but the sprayer has to carry out the spraying operation for a long time, and thus the worker has a problem that the work efficiency is low, and in the latter case, the operator has to apply the sprayer. Although the spraying can be sprayed for a long time while moving in traction, the spray nozzle is sprayed only at a certain height, and the spraying effect is not evenly distributed according to the growth level of the crop. The spraying liquid was continuously sprayed from the spraying nozzle, causing unnecessary waste of the spraying liquid due to excessive spraying, but rather damaging the crops.

In the case of the latter traction spreading device, most of them were cart-type or the rear wheels were fixed, so that it was very inconvenient for the worker to move from side to side during traction spreading.

Therefore, an object of the present invention is to selectively adjust the height and the spraying direction of the spray nozzle according to the type of crop and the degree of growth, evenly spraying the pesticide spray liquid to the crops, excellent control effect, unnecessary spray as a selective control spray of the spray nozzle It is to provide a pesticide spreader to prevent the waste of liquid.

Still another object of the present invention is to provide a crop spreader that can be smoothly sprayed while moving the narrow passage between the crops while being able to adjust the direction according to the rotation of the rear wheel while miniaturizing and lightweighting the pesticide spreader.
