Description

Unmanned automated pesticide spraying device {UNMANNED AUTOMATIC AGRICULTURAL CHEMICALS SPREADER}

The present invention relates to an unmanned automated pesticide spraying device, and more particularly, to an unmanned automated pesticide spraying device for dispensing drugs by remote operation.

In general, in cultivating crops (such as rice or red pepper), pesticides are sprayed to protect the crops from various pests.

General pesticide spraying method except for large-scale pesticide spraying by airplane.If the pesticide spraying area is small, for example, if you want to spray pesticides on crops grown in a small area such as a garden, the worker directly sprays the sprayer. Pesticide spraying was carried out by hand, and when spraying pesticides on a relatively large area such as paddy fields or fields, the hydraulic load generated during operation of the tractor was hung by attaching a loading tray equipped with a pesticide spraying sprayer and a hose winding device to the tractor. The pesticide spraying device and the hose winding device are driven to spread the pesticides over a large area of farmland in a short time.

However, spraying pesticide with a pesticide sprayer on the shoulder is cumbersome to use and is limited to a small amount of spraying, and spraying work using a pesticide spraying sprayer spreading over a large area is carried out by the operator holding the nozzle tube up and down and left and right. It requires a lot of labor because the worker has to carry the heavy load and work while dragging and spraying the hose that supplies the weight of the nozzle tube and the pesticides while spraying it. Because of the dependence, the work efficiency was extremely low.

In particular, since the worker is spraying while holding the nozzle in the spraying position, it is likely that the pesticide is directly in contact with the worker, thus increasing the damage of the pesticide to the worker. It has caused fatal harm to health.

The present invention was devised to solve the above problems, an object of the present invention is to move while spraying the chemicals such as pesticides on the crops after entering the inside of the paddy field or field by controlling from a remote location, with the reduction of labor costs It is to provide an unmanned automated pesticide spraying device that can make cumbersome and difficult pesticide spraying operations more convenient.

In addition, another object of the present invention to provide an unmanned automated pesticide spraying device that can reduce the damage of pesticides by blocking the inflow into the human body through the respirator during the spraying process of pesticides.

In addition, another object of the present invention is to provide an unmanned automated pesticide spraying device that can easily spray the drug in multiple directions to facilitate the adjustment of the angle of the injector.

In addition, another object of the present invention is to provide an unmanned automated pesticide spraying device that is designed to be possible to move left / right in addition to the forward / backward movement to facilitate the pesticide spraying operation.

The structure of the present invention for achieving the above object, in the unmanned automated pesticide spraying device for spraying the medicament to protect the crops from various pests, the rotating plate 15 to be rotated by the first motor 18 inside one side It is installed, the main body 10 is provided with a moving wheel 12 on the edge; A medicine container 20 installed to store a medicine on an upper portion of the other side of the main body 10; A spraying rod (30) connected to the medicine container (20) and spraying the medicine to the crops by the operation of the pump (25); A spraying rod support body 40 coupled to the spraying rod 30 and installed to be moved up / down by a height adjusting member while being supported by the folding frame 42 on the rotating plate 15; It characterized in that it comprises a controller 50 for controlling the first motor 18, the pump 25 and the height adjustment member.

Here, the injection rod 30 is bound to the fixed cap 35 rotatably installed on the upper portion of the injection rod support 40, one side penetrates through the injection rod support 40, the second motor 65 Gear groove coupled to the other side, while the other side is rotated by the driving of the second motor 65 while being fixed to the fixing cap 35 via the fitting hole 64, the guide groove formed in the longitudinal direction of the fixing cap 35. Preferably, the rotation bar 60 is moved along the 36.

At this time, the height adjusting member is mounted on the support 70 is coupled to the lower side of the rotating plate 15, the third motor 72 and spaced apart from the rotating plate 15, the third motor 72 It is preferable that the support shaft 74 is geared to one side and the other side of the support shaft 74 is screwed to the support tube 76 is installed on the bottom surface of the injection support body 40 so that the lead / withdrawal Do.

On the other hand, the front and rear of the main body 10, respectively, the support piece 80 is installed, the body lifting portion 82 for elevating the main body 10 while being lowered by the lowering means inside the support piece 80 ), And auxiliary wheels 84 which are installed at both lower sides of the body lifting unit 82 and are connected to and driven by a fourth motor 86 are further installed.

According to the present invention configured as described above, by controlling the remote site to enter the spreading device into the paddy field to spray pesticides on crops, such as rice, it is possible to reduce the labor cost, especially carrying a hose connected to the spray By eliminating cumbersome and difficult tasks, pesticide spraying can be done easily and conveniently.

In addition, by blocking the inflow into the human body through the respiratory system during the spraying process of pesticides, there is an effect that can reduce the damage caused by pesticides, such as safety accidents due to inhalation of the pesticides.
