Then the staff pulls the pressing plate 45 upwards, so that the pressing plate 45 drives the connecting plate 48 to slide inside the installation cylinder 44, and then through the connection relationship between the connecting block 49 and the connecting groove 50, the connecting block 49 will slide on the inner wall of the installing cylinder 44, Then the first spring 47 will be stretched, and the pressing plate 45 will be rotated at the same time, so that the pressing plate 45 will drive the connecting plate 48 to rotate inside the installation cylinder 44, and then the motor 38 will be placed on the top of the slide plate 60, so that the output shaft of the motor 38 will pass through the opening 39 and the sliding port 21 and extend to the inside of the drive cylinder 36, and insert the block 41 into the slot 40, then reversely rotate the pressing plate 45, so that the pressing plate 45 is located at the top of the motor 38, and at the same time, through the action of the first spring 47, Insert the projection 46 at the bottom of the pressing plate 45 into the groove 43 at the top of the mounting plate 42 to fix the motor 38, then start the motor 38, the motor 38 drives the block 41 to rotate, and the block 41 is connected to the slot 40 The effect will make the transmission cylinder 36 rotate, and the transmission cylinder 36 will drive the four bevel gears 37 to rotate. Through the meshing connection relationship between the bevel gear four 37 and the bevel gear three 34, the bevel gear three 34 will be rotated, and the bevel gear three will be rotated. 34 drives the fixed cylinder 25 to rotate, and the fixed cylinder 25 will drive the first internally threaded cylinder 24 to rotate, through the thread connection relationship between the first internally threaded cylinder 24 and the fixed screw rod 23 and the sliding action of the output shaft of the motor 38 and the stable groove 29, The first internally threaded cylinder 24 will move outside the fixed screw rod 23, and the fixed cylinder 25 will drive the T-shaped threaded rod 26, the second internally threaded cylinder 27 and the scraper 28 to rotate synchronously, and then the scraper 28 will move in the row. The inside of the barrel 6 rotates and moves;

At the same time, the rotation of the fixed cylinder 25 will drive the T-shaped threaded rod 26 to rotate, and the T-shaped threaded rod 26 will drive the bevel gear one 31 to rotate outside the fixed screw mandrel 23, and the bevel gear two 33 will be fixed to make the bevel gear one. 31 rotates on the outside of the bevel gear 2 33, and then the T-shaped threaded rod 26 will rotate on its own during the external rotation of the fixed screw rod 23, and then through the thread relationship between the T-shaped threaded rod 26 and the second internally threaded cylinder 27 and Cooperating with the sliding connection relationship between the stabilizing groove 29 and the stabilizing block 30, the second internally threaded barrel 27 will slide outside the T-shaped threaded rod 26, and then adjust the distance between the two scrapers 28 according to the inner wall size of the discharge pipe 6, which is convenient The scraper 28 is in close contact with the inner wall of the discharge pipe 6. When the scraper 28 is in close contact with the inner wall of the discharge pipe 6, the rotating screw 54 is reversely rotated, so that the rotating screw 54 drives the T-shaped connecting rod 52 to move. The T-shaped connecting rod 52 drives the extension cylinder 56, the fixed rod 57, the socket cylinder 32 and the second bevel gear 33 to move, so that the second bevel gear 33 and the first bevel gear 31 are out of meshing connection, and then the scraper 28 is rotated. Scratching the inner wall of the discharge pipe 6 during the moving process realizes the cleaning of the inner wall of the discharge pipe 6, effectively realizes the dredging of the discharge pipe 6, and then provides convenience for the discharge of the ball mill body 3.
