Description

Technical Field

[0001] The utility model relates to the field of crop tools, in particular to a pesticide spraying device for rice planting. Background Technique

[0002] Rice is a crop widely planted in the subtropics. Half of the people in the world eat rice. China started planting rice more than six or seven years ago and has a long cultivation history. Rice is not only the main food, but also plays an important role in the economy of mankind. During the planting process of rice, pesticides need to be sprayed in stages. Mainly, fungicides are used to kill the germs carried on the surface of seeds, control the occurrence of bakanae disease of rice, and ensure the quality and yield of rice.

[0003] At present, a Chinese patent discloses a pesticide spraying device for rice planting, with the application number CN2021207472511. In the technical solution of this application, through six fixed rods, the angle of adjustment of the sliding plate is increased, which is convenient for users to adjust to a suitable angle for spraying.

[0004] Combined with the above-mentioned disclosed technical solution, when spraying pesticides, it is not convenient to adjust the spraying angle, making it more cumbersome to use and unable to adjust the spraying height and distance, reducing the scope of use of the device. Moreover, during the process of spraying pesticides, due to long-term operation, the pesticides in the water tank will precipitate at the bottom of the water tank, resulting in uneven pesticide spraying, reducing the utilization rate of pesticides, and affecting the quality of subsequent rice output. Therefore, we propose a pesticide spraying device for rice planting to solve this problem. Content of the Utility Model

[0005] To solve the technical problems of rice pesticide spraying, the utility model provides a pesticide spraying device for rice planting.

[0009] As a further improvement of the above solution, one end of the moving frame is fixedly connected with a fixed handle, and moving wheels are fixedly connected to the four corners of the bottom, which is convenient for moving the device.

[0010] As a further improvement of the above solution, a limit ring is fixedly connected to the outer side of the sliding rod, and a through hole for the sliding rod to penetrate is formed on the surface of the moving frame to limit the moving distance of the lifting plate.

[0011] As a further improvement of the above solution, the bevel gear set is composed of two meshing bevel gears A and bevel gears B. The bevel gear A is connected to the output end of the first motor, and the bevel gear B is sleeved on the outer side of the threaded rod, so that the first motor can drive the threaded rod to rotate.

[0012] As a further improvement of the above solution, a strip-shaped groove for the rotating rod to penetrate is formed on the surface of the L-shaped rod, so that the rotating rod is limited to move in the strip-shaped groove.

[0013] As a further improvement of the above solution, stirring rods are arranged at equal intervals and staggered on the surface of the stirring shaft to prevent the pesticides in the water tank from precipitating;

[0014] An inlet is installed at the top of the water tank, and a drain pipe is installed at one side of the bottom of the water tank, which is convenient for adding water and pesticides and discharging the water-pesticide mixture.

[0015] As a further improvement of the above solution, the telescopic rod is composed of a sleeve and a rod. The rod penetrates through the sleeve. Through grooves are arranged at equal intervals on the surfaces of the sleeve and the rod, so that the rod can extend out of the sleeve;
