Since transmission 6 is arranged in shell 7, the opening of shell 7 is covered by cover plate 8, and output shaft 9 is inserted into the inside of shell 7 through the perforation, which effectively prevents the pollution of mud and water to the connection between output shaft 9 and driving shaft 60, and maximally protects transmission 6, reduces the maintenance difficulty and cost of transmission 6.

[0024] The outer wall of the shell 7 is provided with a flange plate 71 outside the opening, the cover seals the opening and is attached to the flange plate 71, a sealing ring 72 is arranged between the cover and the flange plate 71 and is locked by a plurality of bolts 73, so that the cover and the shell 7 can be reliably connected and have good sealing performance. The side of the cover away from the shell 7 is provided with a tubular base 81, the base 81 is coaxially arranged with the through hole, a sleeve 82 is arranged on the outer side of the base 81, and the sleeve 82 and the base 81 are connected by threads; the length of the sleeve 82 is greater than the length of the base 81, two flow resistance rings 83 are arranged on the inner side of the sleeve 82 and outside the base 81, the two flow resistance rings 83 are arranged at intervals, and the inner diameter of the flow resistance ring 83 close to the base 81 is smaller than the inner diameter of the flow resistance ring 83 away from the base 81. After the cover plate 8 and the shell 7 are locked, the sleeve 82 is screwed on the base 81, at this time, one end of the sleeve 82 is attached to the cover plate 8, and the other end of the sleeve 82 extends to the outer side of the base 81, so that the two flow resistance rings 83 form an obstacle to the mud, effectively reducing the probability of mud entering the shell 7, thereby reliably protecting the transmission 6.

[0025] Two assembly rings 84 and a pressing ring 85 are arranged in the sleeve 82, the two flow resistance rings 83 are respectively and one by one arranged in the two assembly rings 84, the flow resistance ring 83 and the assembly ring 84 are interference fit, and the outer wall of the assembly ring 84 is attached to the inner wall of the sleeve 82; a limiting ring 86 is arranged between the two assembly rings 84, the end face of the limiting ring 86 is attached to the end face of the assembly ring 84, and the pressing ring 85 is screwed on the end of the sleeve 82 away from the base 81 and presses the assembly ring 84. A spring 87 is also arranged in the sleeve 82, the spring 87 is sleeved on the outer side of the output shaft 9, one end of the spring 87 is attached to the end face of the base 81, and the other end of the spring 87 is attached to the end face of the assembly ring 84 close to the base 81. A plurality of lever rods 850 are arranged on the inner wall of the pressing ring 85, the plurality of lever rods 850 are arranged at equal intervals along the same circumference, and the axis of the lever rod 850 points to the axis of the pressing ring 85.

[0026] The assembly ring 84 and the flow resistance ring 83 can be prefabricated into a single flow resistance assembly, after the sleeve 82 is screwed on the base 81, the spring 87, a flow resistance assembly, the limiting ring 86 and another flow resistance assembly are sequentially put into the sleeve 82, and then the pressing ring 85 is screwed into the sleeve 82 by threads until the spring 87 is completely compressed, so that the two flow resistance assemblies can be reliably placed in the sleeve 82, and after the pressing ring 85 is unscrewed, the spring 87 can directly push the flow resistance assembly out to the outer side of the sleeve 82, facilitating cleaning or replacement of the flow resistance assembly, ensuring that the flow resistance does not affect the normal rotation of the output shaft 9. Further, by arranging the lever rod 850, the disassembly difficulty of the pressing ring 85 is reduced, and the lever rod 850 can play a role in intercepting larger debris such as cloth strips and plastic bags, preventing these debris from being stuck between the flow resistance ring 83 and the output shaft 9.

[0027] The outer wall of the shell 7 is provided with a conveying pipe 74, which can convey gas or water into the shell 7. During the operation, gas can be conveyed into the shell 7 through the conveying pipe 74, so that the air pressure inside the shell 7 is greater than the air pressure outside the shell 7, thereby improving the flow resistance effect. After the operation is completed, water can be conveyed into the shell 7 through the conveying pipe 74, and the cover plate 8 is opened, thereby realizing the flushing effect of the shell 7.
