The design of the groove 187 makes the driven shaft 186 not interfere with the rotation of the belt 188 when it rubs against the rotating part 1812. To cause obstruction, a belt 188 is movably connected between the groove 187 and the driving shaft 184 , and the driven shaft 186 is attached to the back of the hopper 11 .

The hopper 11 is composed of a frame part 1811 and a rotating part 1812. The rotating part 1812 is rotatably connected to the middle part of the frame part 1811, and the upper and lower ends of the rotating part 1812 are movably embedded inside the frame part 1811 to prevent the hopper 11 The internal mud is taken out of the hopper 11 by the rotating part 1812, and the rotational resistance between the rotating part 1812 and the frame part 1811 is smaller than the frictional resistance between the driven shaft 186 and the rotating part 1812, ensuring that the rotating part 1812 can rotate smoothly .

Both sides of the drive shaft 184 are fixedly connected with a movable shaft 189, and the movable shaft 189 moves through the inside of the fixed seat 183, and a torsion spring 1810 is fixedly connected between the movable shaft 189 and the fixed seat 183.

By adopting the above-mentioned technical solution, since both the pressing plate 1815 and the rotating portion 1812 are made of magnetic materials, and the holding plate 1815 and the rotating portion 1812 are opposite magnetic poles, when the rotating portion 1812 rotates, a magnetic attraction will be generated on the pressing plate 1815 , so that the pressing plate 1815 slides downward inside the second chute 1813 through the second slide block 1814, thereby using the pressing plate 1815 to push the mud in the hopper 11 to the discharge port, further ensuring the smooth discharge of the hopper 11 , and because the attractive force between the pressing plate 1815 and the rotating part 1812 is greater than the elastic force of the spring 1816, and the magnetism on the surface of the rotating part 1812 is distributed indirectly, the magnetic attraction of the rotating part 1812 to the pressing plate 1815 is also intermittent When the magnetic area of the rotating part 1812 rotates to the bottom of the pressing plate 1815, it will drive the pressing plate 1815 to move down. Under the action of the spring 1816, it is pulled upwards, so that the pressing plate 1815 forms an intermittent reciprocating push to the mud.
