The present invention relates to a spreader and a method for spraying pesticides and fertilizers, and in particular, since the spraying of pesticides and fertilizers can be performed automatically and unattended, the spraying manpower can be reduced and the spraying cost can be reduced as much as possible. The present invention relates to an unmanned automatic spreader and its spraying method, which can prevent poisoning by pesticides and thus improve public health.

In general, the spraying method of pesticides and fertilizers currently being carried out in rural areas is carried out by diluting the pesticides in water and spraying them in a sprayer or spraying them in a long plastic bag and holding a plastic bag at both ends.

However, this conventional spraying method is the most primitive work method that can injure the health by a large number of people are addicted to pesticides, there is a problem that can not easily obtain the spraying staff currently depleted rural workers. There is also a method in which the plane sprays pesticides and fertilizers by using agricultural machines such as helicopters, but this method is suitable for large-scale farming and not for small-scale farmers who farm small areas such as Korea.

The purpose of the present invention is to solve such problems, and can greatly reduce the current manpower of spraying rural population, which can solve the labor shortage and can efficiently and quickly spread pesticides and fertilizers to Uruguay Round. It is to provide an unmanned automatic spreader and spreading method that can enhance the competitiveness of the company.

This object of the present invention is a pesticide or fertilizer spraying agent is stored in the liquid or powder form, and the lower part of the supply pipe is provided with a storage unit and a control valve is installed, and the suction pipe is connected to the supply pipe of the storage unit and one end is formed water It is achieved by an unmanned automatic spreader comprising a suction unit having a stirrer and stirring the spraying agent, and a spraying rod that is connected at one end to the suction unit at all times and is assembled to be suitable for the type of farmland to be sprayed.

Hereinafter, with reference to the accompanying drawings unmanned automatic spraying machine according to the present invention will be clearly understood by one embodiment described in detail below.

1 is a schematic perspective view schematically showing an embodiment of the unmanned automatic spreader according to the present invention, and FIG. 2 is a schematic cross-sectional view for schematically showing the shape of the storage and suction portions of the unmanned automatic spreader of FIG. 3 (a) and 3 (b) are plan views showing a shape in which the shape of the spread bar is deformed to enable spraying according to the farmland to be sprayed, and FIG. An example is shown.

As shown in the figure, the unmanned automatic spreader (A) according to an embodiment of the present invention is spraying agent is stored and the spraying agent storage unit 3 is installed on the spraying agent supply pipe (1) formed on the lower spraying agent control valve (2) and The supply pipe 1 of the spreading agent storage unit 3 is connected to one end thereof, and a suction end 4 for sucking water is formed and a stirrer 5 for stirring water and the spreading agent is connected to the power unit M. And a plurality of connecting sockets having a spray nozzle 7 so as to be detachably connected to one end of the suction part 6 and the suction part 6 and to be detachably connected to the form of the farmland B to be sprayed. (8) and the spreader 10 connected by the pipe 9.

As shown in FIG. 2, the spraying agent stored in the spraying agent storage unit 3 is mixed with the spraying agent 11 and water, stored in the liquid phase, filtered through the filter 12, and supplied to the suction unit 6. However, it is possible to magnetically powder, not liquid, and the spraying agent is discharged through the spraying agent supply pipe 1, and the discharged amount of the spraying agent flowing out is controlled through the spraying agent control valve 2. The suction part 6 for spraying the spraying agent supplied through the spraying agent storage part 3 with water and spraying the spraying agent onto the spraying table 10 has a suction end 4 which sucks water from one end at one end thereof. A filter 13 is attached to the suction end 4 to prevent inhalation of foreign matter. The agitator 5 includes a stirring screw 14 for uniformly mixing the spraying agent and water, and the stirring screw 14 is powered It is rotated by the force of the water sucked by the apparatus M, and the stirring screw 14 rotational force causes the water and the spraying agent to be uniformly stirred.

The power unit M used for the suction unit 6 may use a separate suction motor, but as shown in FIG. 1, a separate motor may be used when using the tiller, as shown in FIG. 1. There is no need to do it.

The spraying table 10 detachably coupled to one end of the suction unit 6 is deformed and installed according to the shape change of the farmland B to be sprayed as shown in FIG. 3 (a) (b). It is assembled to make it possible. This change in shape of the spreading table 10 is made possible by a plurality of connecting sockets 8 and the tube (9). Although the connection socket 8 shows only the T-type connection socket and the L-type connection socket, respectively, in FIG. 4 (a) (b), various types of connection sockets may be provided.

The lower part of each connecting socket 8 is fixed to the ground (15) to be fixed to the connection socket is embedded in the ground, the upper through portion (8a) is connected to the spray nozzle (7) for spraying the spreading agent is installed and the horizontal through (8b) Is connected by a tube (9). The injection nozzle (7) used a spray nozzle that is sprayed in a known 360 ° rotation.

The method and effects of using the unmanned automatic spreader according to an embodiment of the present invention having such a configuration will be described in detail below.

Install a spray table (10) in the rice paddy field. Installation of the spreading stand 10 is most suitably installed in the form of discussion.

After the installation of the spreading table 10 is completed, one end of the spreading table 10 is connected to the suction unit 6, and the suction end 4 of the suction unit is immersed in an agricultural water passage through which agricultural water flows or a stored container of water, and the spreading agent storage unit 3 When the spreading agent control valve 2 is opened at an appropriate ratio and the power unit M is operated, the spraying agent having passed through the spreading agent control valve 2 is sprayed at the suction end It is uniformly stirred by the stirring screw 14 in the sucked water and the stirrer 5 and passed through the inhaler and sprayed into the paddy field through the spray nozzle 7 of the spreading table 10. Since the spray nozzle 7 of the spreading table is arranged at regular intervals by calculating the spray radius of the spray nozzle so that the spreading of the spreading agent can be applied to all parts of the field, overspreading of the spreading agent is also prevented. In addition, since the height of the spray nozzle 7 is changed as shown in FIG. 5 without making the height of the spray nozzle 7 of the spreading table of the present invention constant, it is possible to simultaneously spray the front and back surfaces of the crop. Effective pesticide application has also been made possible.

After the spraying of the spreading agent is finished in this manner, the one end of the spraying table 10 and the suction unit 6 are released, and the spraying table is installed in the paddy field and moved to another spraying station. Spray spreader on farmland. In this way, the spray table is placed on the paddy field and the suction part is used when spraying, so simply installing the spray table on the paddy field makes it easy to spray rice paddies that require the application of pesticides and fertilizers several times a year. It will be done.

As described above, the unmanned automatic spreader and the spraying method according to the present invention can drastically reduce the workforce in rural areas where the rural population is declining, and can prevent the poisoning of the spraying workers into pesticides in advance. It can be said that it has a large policy effect in the national sense that it can strengthen the agricultural competitiveness of the aging farming village caused by this agricultural phenomenon by lowering the morale of domestic farmers.
