Description

[0001] The present invention relates to an agricultural spray apparatus having foreign matter discharging means,

The present invention relates to an agricultural spraying apparatus having a foreign matter discharging means, and more particularly, to an agricultural spraying apparatus having a foreign matter discharging means, and more particularly, to an agricultural spraying apparatus having a foreign matter discharging means, A filter unit having a discharge pipe path through which the foreign matter filtered by the filter is formed, and a discharge hole penetratingly corresponding to the discharge pipe duct of the filtration unit, And a foreign matter discharging means for discharging the foreign matter to the outside easily by using a system closing mouth provided to the outside.

Conventionally, the agricultural spraying apparatus used in the conventional art is sprayed through a chemical liquid spraying head through a chemical liquid hose when a chemical liquid is formed at a high pressure in a high pressure atomizer, and the chemical solution spraying stand is moved by a worker to control the pest insecticide.

At this time, the chemical liquid jetting plate is required to be injected at a long distance in the case of fruit water or rice, and in the case of various kinds of vegetables, near diffusive jetting is required. In order to spray the chemical liquid in a uniform distribution, The injection state is controlled and the chemical liquid is injected while moving.

As described above, in order to perform the long-distance injection and the near-diffuse injection of the chemical liquid, the conventional chemical liquid injection valve has a chemical liquid injection head body having a chemical liquid hose connection portion, a chemical liquid supply pipe at the center point, and a nozzle body at the front end. And a control rod provided with a vortex forming part is inserted into the liquid injection valve and connected to the spiral groove of the body of the chemical liquid injecting body by a fastening screw. And a spiral shaft is provided at the rear portion so as to be coupled to the spiral groove at the tip of the injection control rod, , And a vortex forming member having a conical surface on the front and rear sides and a screw groove on the rear conical surface, The bar is known, as in No. 20-2073805.

However, the above-described technology has a problem that the injection control bed formed for long-distance injection and near-diffuse injection of the chemical liquid is formed long, and the cost of production is increased. In addition, in recent years, for aged farmers, There is a problem that the weight of the product is heavy and the length of the injection control unit is long and it is easily broken at the operation. In order to stop the spraying of the chemical liquid, stop the operation of the high pressure atomizer or shut off the valve provided in the chemical liquid hose, There is a problem that the injection can be stopped.

In order to solve the problem that the weight of the product as described above is heavy or the injection of the chemical liquid can be stopped only when the valve is closed, a water splitter having a spray hole on the front surface and a handle having a ' A water spraying part having a water distribution pipe formed in the inside of the rotating body and a water circulation part fixed to the water dispersion part by a connection clip, And an operation knob is formed to be spaced apart from the mounting groove so that a rear end of the water distribution pipe can be inserted therein. A handle pipe is formed at the lower end of the operating part, and a hose connecting port is formed at the end of the handle pipe This technique is configured to include a handle is generated a known bar as in Patent Publication No. 10-0739854 call.

However, the above-mentioned technique has a problem that the rotating body must always be returned for the long-distance injection and the near-diffuse injection of the chemical liquid, and the chemical liquid can not be sprayed at a distance other than the long-distance injection or the near-field diffusion injection.

In addition, when foreign substances are infiltrated into the above-mentioned products, there is a problem that the product is completely decomposed to remove foreign substances, or when the foreign substances are not removed, the products must be discarded.

Accordingly, there is a need for an agricultural spraying apparatus having a foreign matter discharging means that solves the above-described conventional problems.
