The bucket-shaped cover body 901 is set at the lower position of the impeller component 4, wherein the bucket-shaped cover body 901 also corresponds to the setting position of the cutting blade 805, and the bucket-shaped cover body 901 is set at the upper position of the cutting blade 805; the annular side skirt 902 is provided with mounting holes at equal intervals, and the outer wall surface of the annular side skirt 902 is adapted to fit the inner wall of the trumpet-shaped water inlet 7, and the annular side skirt 902 is fixed by fixing screws; a flow hole body 904 is also provided in the bucket-shaped cover body 901, and the outer hole position of the flow hole body 904 is provided. A filter cone tube head 905 is fixedly provided, and the filter cone tube head 905 and the flow hole body 904 are set in corresponding positions and have the same number of groups. One end of the filter cone tube head 905 is connected to the flow hole body 904, and the other end of the filter cone tube head 905 is provided with a filter through-hole, wherein the end of the filter cone tube head 905 provided with the filter through-hole is the small-mouth end, and the large-mouth end of the filter cone tube head 905 is connected to the flow hole body 904; auxiliary collection grooves 906 are equidistantly provided on the outer wall of the bucket-shaped cover body 901, and auxiliary scraping strips 907 are equidistantly provided in the auxiliary collection grooves 906, and the auxiliary scraping strips 907 are equidistantly provided in a straight line in the auxiliary collection grooves 906.

[0035] In order to prevent the cut debris from accumulating at the filter through-hole position at the end of the filter cone pipe head 905 and affecting the pumping work during long-term operation, the present invention also provides auxiliary accessories on the side of the supporting disc 804, wherein the auxiliary accessories are connected and arranged at the side position of the supporting disc 804, wherein the auxiliary accessories include a positioning plate 1001, a supporting strip 1002, a cleaning brush strip 1003 and an auxiliary barb 1004; a positioning plate 1001 is fixedly provided at one end of the supporting strip 1002, and the positioning plate 1001 is set as an arc-shaped plate, and the positioning plate 1001 is adapted to fit the side wall of the supporting disc 804, and the positioning plate 1001 is fixed by a set fixing screw; The cleaning brush strips 1003 are evenly fixed on the side walls of one side, and auxiliary barbs 1004 are equidistantly provided on the side walls of the cleaning brush strips 1003. The cleaning brush strips 1003 correspond to the setting positions of the bucket-shaped cover 901, and the cleaning brush strips 1003 face the bucket-shaped cover 901, and the carrying strips 1002 are tilted; that is, while the cutting blade 805 is driven by the carrying disc 804 to cut the long strips of debris, the carrying disc 804 will also drive the carrying strips 1002 to rotate, wherein the cleaning brush strips 1003 arranged on the side walls of the carrying strips 1002 will scrub the outer wall of the bucket-shaped cover 901, mainly to prevent debris from accumulating at the filter through-hole position at the end of the filter cone pipe head 905 The filter cone 905 is preferably a filter element, and the filter cone 905 is preferably a filter element. The filter cone 905 is preferably a filter element, and the filter cone 905 is preferably a filter element. The filter cone 905 is preferably a filter element, and the filter cone 905 is preferably a filter element. When passing through the auxiliary collection groove 906, the cleaning brush strip 1003 can also clean the debris accumulated in the auxiliary collection groove 906 or entangled and blocked on the auxiliary scraping strip 907.

Similarly, the auxiliary scraping strip 907 has a corresponding cleaning effect on cleaning the debris adhered to the cleaning brush strip 1003, thereby preventing the debris from accumulating too much on the cleaning brush strip 1003. On the one hand, it provides a guarantee for the cleaning work of the cleaning brush strip 1003 itself, and on the other hand, it reduces the burden of subsequent cleaning work on the cleaning brush strip 1003.

[0036] In order to facilitate the later disassembly and maintenance, the cutting anti-winding mechanism in this scheme is detachably arranged, that is, when installing the cutting anti-winding mechanism, first align the first fixed disk 801 with the bottom end axial surface of the transmission shaft body 3, and then fix it with fixing screws so that the axes of the connecting shaft body 802 and the transmission shaft body 3 are in a straight line; then install and fix the bucket-shaped cover body 901, and the diameter of the through groove 903 at the center position of the bucket-shaped cover body 901 is equal to the diameter of the second fixed disk 803, and the annular side skirt 902 on the side of the bucket-shaped cover body 901 is brought into contact with the inner wall of the trumpet-shaped water inlet 7. During this process, the second fixed disk 803 passes through the center position of the bucket-shaped cover body 901. The through slot 903 is then fixed with fixing screws, and the installation and fixing work of the bucket-shaped cover body 901 is completed; then the carrying plate body 804 is installed on the second fixing plate 803 at the bottom end of the connecting shaft body 802, that is, the carrying plate body 804 is aligned with the bottom end disk surface of the second fixing plate 803, and then fixed with fixing screws; in this solution, the auxiliary accessories can also be disassembled separately, that is, the positioning plate 1001 at one end of the carrying strip body 1002 is fixed to the side wall of the carrying plate body 804 by fixing screws, and when replacement and cleaning and maintenance work is needed later, in order to improve the convenience of cleaning the cleaning brush strip body 1003, the carrying plate 804 can be removed separately. The strip carrying body 1002 can be disassembled, so as to facilitate the cleaning work of the cleaning brush strip body 1003. After completing the installation and fixing work of the carrying disc body 804, the installation work of the cutting anti-winding mechanism can be completed, and the operation is convenient. When it is necessary to disassemble it later, the carrying disc body 804 needs to be disassembled first, that is, the fixed connection between the carrying disc body 804 and the second fixed disc 803 is released. After the disassembly work of the cutting blade 805 and the auxiliary accessories is completed, the bucket-shaped cover body 901 needs to be disassembled again, that is, the connection and fixing of the annular side skirt 902 on the side of the cover mouth of the bucket-shaped cover body 901 and the trumpet-shaped water inlet 7 can be released. Then the bucket-shaped cover body 901 can be disassembled along the connecting shaft body 802. The axial direction is translated until the through slot 903 at the center of the bucket-shaped cover body 901 is separated from the second fixed plate 803, and then the bucket-shaped cover body 901 is removed. If it is also necessary to disassemble the connecting shaft body 802, the fixed connection between the first fixed plate 801 and the bottom end of the transmission shaft body 3 can be directly released. If the provided trumpet-shaped water inlet 7 hinders the disassembly of the connecting shaft body 802, that is, it is inconvenient for the staff to perform the disassembly work, the trumpet-shaped water inlet 7 can be disassembled first, that is, the connection and fixation between the trumpet-shaped water inlet 7 and the upper trumpet cover 6 can be released. After the trumpet-shaped water inlet 7 is removed, the connection and fixation between the first fixed plate 801 and the transmission shaft body 3 can also be released.The purpose of making the auxiliary accessories removable is to better adapt to work needs. When using the cleaning brush strip 1003 to clean debris from the bucket-shaped cover 901, the auxiliary accessories can be omitted, that is, the supporting strips 1002 are not installed on the side walls of the supporting plate 804. When the auxiliary accessories are needed, different sets of supporting strips 1002 can be selected and installed according to actual needs, providing good work flexibility.
