Two second transmission sprockets 24 are rotatably assembled on the inner walls of the front and rear sides of the sludge tank 1, and the two second transmission sprockets 24 are staggered up and down;

[0029] The two first transmission sprockets 23 and the two second transmission sprockets 24 on the rear side and the two first transmission sprockets 23 and the two second transmission sprockets 24 on the front side are respectively jointly equipped with a first transmission chain 25, and the two mounting seats 31 are respectively fixedly mounted on the two first transmission chains 25. A mounting groove 26 is opened at the upper rear part of the sludge tank 1, and one end of the main transmission shaft 21 extends into the mounting groove 26 and is fixedly installed with a third transmission sprocket. A motor 27 is fixedly installed at the upper rear part of the sludge tank 1, and the output shaft of the motor 27 is fixedly installed with a fourth transmission sprocket 28. A second transmission chain 29 is assembled for transmission between the third transmission sprocket and the fourth transmission sprocket 28.

[0030] When in use, it is only necessary to start the motor 27, the motor 27 drives the fourth transmission sprocket 28 to rotate, the fourth transmission sprocket 28 drives the third transmission sprocket to rotate through the second transmission link 29, and then drives the main transmission shaft 21 to rotate, the main transmission shaft 21 drives the two first transmission sprockets 23 connected thereto to rotate, and drives all the first transmission sprockets 23 and the second transmission sprocket 24 to rotate through the first transmission chain 25, and then drives the scraper mechanism 2 to move, scraping the sludge deposited at the bottom of the sludge tank 1, so that it falls into the mud collecting bucket inside the sludge tank 1.

[0031] The scraper mechanism 3 is provided with a plurality of scraper mechanisms 3, which are evenly distributed and installed on the transmission mechanism 2. The scraper mechanism 3 includes two mounting seats 31 and scrapers 32. The two mounting seats 31 are distributed and installed on the transmission mechanism 2 in a front-to-rear manner. A vertical slot 321 is provided on the side of the mounting seat 31 away from the transmission mechanism 2. An inclined slot 330 connected to the vertical slot 321 is provided on the side of the mounting seat 31 away from the transmission mechanism 2. A connecting port 33 is provided on the inner wall of one side of the vertical slot 321. The scraper 32 is placed inside the two vertical slots 321. A plug-in component connected to the two connecting ports 33 is provided on one side of the scraper 32; the specific plug-in component includes two limit blocks 37, and one side of the scraper 32 has two limit blocks 37 that match the positions of the two connecting ports 33. There are two sliding grooves 34, and a moving groove 35 connected to the two sliding grooves 34 is opened inside the scraper 32. A push plate 36 is slidably assembled inside the moving groove 35. One end of the two limit blocks 37 is fixedly connected to the push plate 36 close to the connecting port 33, and the other ends of the two limit blocks 37 extend into the two connecting ports 33 respectively. A plurality of first springs 38 are fixedly installed on the side of the push plate 36 away from the connecting port 33, and one end of the plurality of first springs 38 are fixedly connected to the inner wall of the moving groove 35 respectively. A rectangular opening 39 connected to the moving groove 35 is opened on the side of the scraper 32 close to the connecting port 33, and a pressing block 391 matching the position of the rectangular opening 39 is fixedly installed on the side of the push plate 36 close to the connecting port 33.

[0032] After the two first transmission chains 25 are installed, the several mounting seats 31 installed on the first transmission chains 25 on the front and rear sides are aligned one by one. When installing the scraper 32, it is only necessary to align the scraper 32 with the two vertical slots 321 and insert it. In the initial state, the elastic force generated by the several first springs 38 will push the two limit blocks 37 out of the chute 34. When the scraper 32 is lowered, one end of the two limit blocks 37 will contact the inclined surfaces of the two inclined slots 330 like the ground, and then the inclined surfaces of the inclined slots 330 generate an extrusion force to push the limit blocks 37 into the chute 34 until the scraper 32 When the scraper 37 is completely inserted into the vertical groove 321, the two limit blocks 37 will align with the two connecting ports 33, and then the first springs 38 will push the two limit blocks 37 into the two connecting ports 33 to complete the connection. Then the position of the scraper 37 is locked and it cannot be pulled out of the vertical groove 321. The installation is fast and efficient. When the scraper 37 needs to be taken out, press the pressing block 391, and the pressing block 391 moves the pushing plate 39. The pushing plate 39 compresses the first springs 38 while driving the two limit blocks 37 to withdraw from the two connecting ports 33. After releasing the lock, the scraper 32 can be pulled out.

[0033] A displacement groove is provided on the side of the scraper 32 away from the connection port 33, and two auxiliary scrapers 331 are slidably assembled inside the displacement groove. A locking assembly is provided between the two auxiliary scrapers 331 and the scraper 32; after the locking assembly is released, the two auxiliary scrapers 331 can slide inside the movable groove, thereby extending or shortening the overall length of the scraper 32 to a certain extent, and is suitable for sludge tanks 1 of different widths.

[0034] The locking assembly includes an insert rod 332, a plurality of insert holes 333 are arranged on one side of the auxiliary scraper 331, a mounting barrel 337 is fixedly installed on one side of the scraper 32, the insert rod 332 is slidably assembled inside the mounting barrel 337, one end of the insert rod 332 extends into one of the insert holes 333, a second spring 334 is fixedly installed on the end of the insert rod 332 away from the insert hole 333, one end of the second spring 334 is fixedly connected to the inner wall of the mounting barrel 337, a pull rod 335 is fixedly installed at the center of the end of the insert rod 332 away from the insert hole 333, one end of the pull rod 335 extends out of the mounting barrel 337 and is fixedly installed with a pull block 336.

[0035] In the initial state, the second spring 334 generates a thrust to push the insertion rod 332 into one of the sockets 333, and the position of the auxiliary scraper 331 is fixed. When the movement of the auxiliary scraper 331 needs to be adjusted, just pull the pull block 336 to make the pull block 336 drive the pull rod 335 to move, and the pull rod 335 drives the insertion rod 332 to withdraw from the connection with the socket 333. Then you can slide the auxiliary scraper 331 left and right, move it to the appropriate position, and then insert the insertion rod 332 into the corresponding socket 333.

[0036] The device is used as follows:

[0037] When in use, after the two first transmission chains 25 are assembled, the mounting seats 31 on the front and rear sides are aligned with each other. When installing the scraper 32, it is only necessary to insert the scraper 32 into the vertical slot 321 opened by the two mounting seats 31. Due to the action of the two inclined slots 330, the two limit blocks 37 will contact the inclined surfaces of the two inclined slots 321, and then the inclined surfaces will generate a contact force to push the limit block 37 back into the slide groove 34 until the limit block 37 is aligned with the connecting port 33. The first spring 38 pushes the limit block 37 into the connecting port 33 to complete the limiting of the scraper 32. The operation is simple and fast. When disassembling, it is only necessary to push the pressing block 391 to unlock and remove the scraper 32. The disassembly is quick and easy to replace the scraper 32.
