Description

Technical Field

[0001] The utility model relates to the technical field of late blight prevention and control, in particular to a potato late blight prevention and control device. Background Art

[0002] Late blight is a devastating oomycete disease caused by Phytophthora infestans. The disease has a fast onset, strong infectivity and great difficulty in prevention. It can infect the stems, leaves and tubers of crops such as potatoes and tomatoes, causing devastating diseases. In order to prevent late blight from damaging crops, pesticides for preventing late blight are generally sprayed on the crops in advance. In the prior art, when spraying pesticides on crops, a sprayer is usually used. The existing sprayers are generally made by connecting a medicine box with a spray pipe. When in use, the pesticide is first poured into the medicine box, and then water is added to the medicine box to dilute the pesticide. Then, the medicine box is carried on the back through the shoulder strap on the medicine box, and the spray pipe is held by hand to spray the crops. In this way, the pesticide in the medicine box is not easily dissolved in water, and during the spraying process, some pesticides will slowly precipitate to the bottom of the medicine box, thus reducing the spraying effect of the pesticide. Content of the Utility Model

[0003] The purpose of the utility model is to provide a potato late blight prevention and control device, which can facilitate the spraying of pesticides on crops, and can facilitate the full dissolution of pesticides in water, preventing the precipitation of pesticides during the spraying process and affecting the spraying effect of pesticides.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A potato late blight prevention and control device includes a base. On one side of the upper end of the base, a medicine box is arranged. On the other side of the upper end of the base, a spraying device communicated with the medicine box is arranged. A moving device is arranged at the lower end of the base. An adding material groove is opened at the upper end of the medicine box. A filter screen is arranged at the lower end inside the adding material groove. A stirring shaft vertically arranged is rotatably connected inside the medicine box. A spiral stirring blade arranged in a spiral shape is arranged on the outer side of the stirring shaft. A first bevel gear is arranged at the upper end of the stirring shaft. A first rotating shaft horizontally arranged is rotatably connected inside the medicine box below the adding material groove. A second bevel gear meshing with the first bevel gear is arranged at one end of the first rotating shaft close to the first bevel gear. An impeller is arranged on the outer side of the first rotating shaft close to the adding material groove;

[0006] Inside the medicine box, a horizontally arranged second rotating shaft is rotatably connected near the first bevel gear. A third bevel gear meshing with the first bevel gear is arranged at one end of the second rotating shaft close to the first bevel gear. A ratchet wheel is arranged at the end of the second rotating shaft far from the third bevel gear and extends out of the medicine box. A limiting disc rotatably connected to the ratchet wheel is rotatably connected to the outside of the second rotating shaft. A pawl cooperating with the ratchet wheel is rotatably connected to one end of the limiting disc close to the ratchet wheel. A shrapnel for restricting its rotation is arranged at one end of the limiting disc close to the pawl. When the moving device rotates away from the spraying device, the pawl does not restrict the rotation of the ratchet wheel. When the impeller drives the stirring shaft to rotate, the pawl does not restrict the rotation of the ratchet wheel. A transmission device is arranged between the limiting disc and the moving device.

[0007] By adopting the above technical solution, during use, pesticides are added through the feeding trough, and then water is added to the medicine box through the feeding trough. The filtering trough can filter impurities in the pesticides and water. The water impacts the impeller through the feeding trough, driving the impeller to rotate. The impeller drives the first rotating shaft to rotate. The first rotating shaft drives the second bevel gear to rotate through the first bevel gear. The second bevel gear drives the stirring shaft and the spiral stirring blade to rotate, stirring the pesticides and water to dissolve the pesticides in the water more quickly. After the pesticide preparation is completed, the base is pushed, and under the action of the moving device, the medicine box and the medicine preparation device are driven to move. The spraying device is started, and the spraying device sprays the pesticides in the medicine box on the crops. During the movement, the moving device drives the limiting disc to rotate through the transmission device. The shrapnel makes the clamping jaw catch the ratchet wheel. The limiting disc drives the ratchet wheel to rotate through the pawl. The ratchet wheel drives the second rotating shaft to rotate. The second rotating shaft drives the second bevel gear to rotate through the third bevel gear, thereby driving the stirring shaft and the spiral stirring blade to rotate, and continuously stirring the pesticides in the medicine box to prevent the pesticides from precipitating.
