Furthermore, the chain is wound on the second pulley, the fourth pulley, the fifth pulley, the scraper, the third pulley and the first pulley in sequence to form a loop.

Further, the support is arranged 2-5m above the bottom frame.

Further, the chain between the first pulley and the second pulley is perpendicular to the base frame.

The utility model achieves the following beneficial effects:

firstly, the utility model is provided with the transmission of the chain connected with the motor and the pulley block, thereby avoiding carrying the sludge to the scratched position, and having simple structure and high sludge scraping efficiency;

secondly, bidirectional mud scraping can be realized by controlling the positive rotation and the negative rotation of the motor, and for positions with more mud, the mud scraping quality can be improved by accelerating the switching frequency and reciprocating the motor back and forth;

thirdly, the utility model has simple structure and convenient assembly and disassembly, and is suitable for sewage treatment tanks with longer distance.

Detailed Description

To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.

As shown in fig. 1-4, a power mechanism of a mud scraper comprises a base frame 3 and a scraper 4 mounted on the base frame 3, wherein the power mechanism 1 comprises a support 11, a motor 12 mounted on the support 11, and a bearing seat 15, and the support 11 is preferably arranged at a position 2-5m above the base frame 3. The output end of the motor 12 is connected with the first pulley 13 through a rotating shaft 14, and the rotating shaft 14 is connected with a bearing seat 15. The chain 2 is wound on the first pulley 13.

The support 11 is also provided with a control box 6 electrically connected with the motor 12, and the control box can control the motor 12 to rotate forwards and backwards to drive the link to rotate forwards and backwards.
