When the feeding hopper 1 needs to be cleaned, the water inlet 3 is connected to the water pipe, water enters the annular water cavity 2 from the water inlet, and then flows out from the water outlet 4 along the inner wall of the feeding hopper 1. At the same time, the cleaning component 5 is driven by the driving component 6 to clean the inner wall of the feeding hopper 1, so as to effectively clean the contaminated soil adhering to the inner wall of the feeding hopper 1, reduce the risk of corrosion of the feeding hopper 1 by certain components in the contaminated soil, and extend the service life of the feeding hopper 1.

[0026] like Figure 1 and Figure 2 As shown, the cleaning component 5 includes a cleaning rod 51 and a cleaning brush 52. The cleaning brush 52 is fixed on the cleaning rod 51. The bristles of the cleaning brush 52 abut against the inner wall of the hopper 1. When the cleaning component 5 cleans the inner wall of the hopper 1, the cleaning rod 51 moves along the inner wall of the hopper 1, and the contaminated soil adhering to the inner wall of the hopper 1 is scraped off by the cleaning brush 52. At the same time, the inner wall of the hopper 1 is brushed clean in cooperation with the water flowing out of the water outlet 4.

[0027] like Figure 1 and Figure 2 As shown, the driving assembly 6 includes a gear ring 61, a gear 62, a driving motor 63 and a mounting plate 64. A connecting groove 611 is provided at the bottom of the gear ring 61. The gear ring 61 is slidably connected to the top of the hopper 1 through the connecting groove 611. The gear ring 61 is meshed with the gear 62. The gear 62 is fixed on the output shaft of the driving motor 63. The driving motor 63 is fixed on the hopper 1 through the mounting plate 64. The upper end of the cleaning rod 51 is fixedly connected to the inner wall of the gear ring 61. Specifically, the driving motor 63 drives the gear 62 to rotate, and then the gear ring 61 rotates on the top of the hopper 1, thereby driving the cleaning rod 51 to move, and the cleaning rod 51 drives the cleaning brush 52 to clean the inner wall of the hopper 1.

[0028] like Figure 2 As shown, the inner side wall of the connecting groove 611 is symmetrically provided with an annular limiting protrusion 612, and the feeding hopper 1 is provided with an annular limiting groove 11 which is matched with the annular limiting protrusion 612, and the annular limiting protrusion 612 is slidably connected with the annular limiting groove 11, wherein the annular limiting protrusion 612 and the gear ring 61 are integrally formed, and the gear ring 61 is limited by the setting of the annular limiting protrusion 612 and the annular limiting groove 11 to prevent the gear ring 61 from falling off from the upper part of the feeding hopper 1 during movement, so that the movement of the gear ring 61 is more stable.

[0029] like Figure 2 As shown, the upper end of the cleaning brush 52 is located below the water outlet 4 to prevent the bristles of the cleaning brush 52 from blocking part of the water outlet 4 and affecting the stable outflow of water.

[0030] like Figure 2 As shown, there are two cleaning components 5, and the two cleaning components 5 are symmetrically arranged. By setting the two cleaning components 5, the cleaning efficiency of the inner wall of the feeding hopper 1 can be improved.

[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
