[0002] High temperature heat damage is a natural disaster that has a serious impact on rice production. During the period from booting to heading, rice is extremely sensitive to temperature, and high temperature weather can easily lead to poor development during flowering, decreased fruiting rate and reduced yield. In order to meet this challenge, we need to take scientific and effective preventive measures, including reasonable irrigation through irrigation machines. As a type of agricultural equipment, irrigation machines are widely used in rice cultivation. When existing irrigation machines pump water in the pool, they may draw organisms in the water into the interior of the irrigation machine, which may not only cause the irrigation machine to malfunction, but also destroy the ecological balance in the pool. Therefore, it is often necessary to add filtering functions to the irrigation machine.

[0021] In this embodiment, when there are too many impurities on the surface of the filter plate inside the filter box 2, the motor 41 is started first. Due to the rotation of the output end of the motor 41, the screw rod 42 is driven to rotate, and then the lifting component 44 is driven to slide up and down, and slide on the surface of the guide rod 43. Since the lifting component 44 slides up and down, the cleaning roller 45 is driven to move on the surface of the filter plate. At the same time, when the cleaning roller 45 moves up and down, since the gear 46 meshes and rolls on the surface of the toothed plate assembly 47, the cleaning roller 45 moves up and down on the surface of the filter plate and slides relatively, so that the impurities on the surface of the filter plate can be adsorbed and cleaned, thereby preventing the filter screen of the filter plate from being blocked, thereby improving the irrigation efficiency of this device.

[0022] Specifically, the tooth plate assembly 47 includes a U-shaped plate 471, the U-shaped plate 471 is arranged inside the filter box 2, the U-shaped plate 471 is arranged inside the guide plate 472, the U-shaped plate 471 is slidably connected to the tooth plate 473 through the guide plate 472, the tooth plate 473 and the gear 46 are meshed with each other, and the surface of the U-shaped plate 471 is threadedly connected to a threaded rod 474, the threaded rod 474 penetrates the U-shaped plate 471 and is rotatably connected to the tooth plate 473 through a ball bearing.

[0023] In this embodiment, when it is necessary to adjust the cleaning strength of this mechanism, first rotate the threaded rod 474, thereby driving the tooth plate 473 to slide on the surface of the guide plate 472, and then drive the cleaning roller 45 to move through the gear 46, thereby changing the cleaning strength of this mechanism by changing the squeezing strength of the cleaning roller 45 on the filter plate.
