One pulley is installed on the outside of the second transmission short shaft 123, and the other pulley is installed on the outside of the third transmission short shaft 125. The belt is wound between the two pulleys. A positioning gear 126 is fixed to the inside of the third transmission short shaft 125. A feeding ramp 128 is slidingly provided on the upper left side of the processing bottom cylinder 7. The feeding ramp 128 can facilitate the cement to enter the processing bottom cylinder 7.

[0048] First, the operator pours an appropriate amount of cement into the loading hopper 111. When people use this device, the second photoelectric sensor 1120 monitors the material in the processing bottom cylinder 7. The second photoelectric sensor 1120 detects that the material in the processing bottom cylinder 7 corresponds to it through the transparent observation window. The second photoelectric sensor 1120 sends a signal. After receiving the signal, the control module controls the telescopic rod of the electric push rod 1113 to extend. The extension of the telescopic rod of the electric push rod 1113 drives the positioning connection block 1114 to move right. The positioning connection block 1114 moves to the right and drives the limit cross bar 1115 to move to the right. The limit cross bar 1115 moves to the right and drives the first transmission gear 1117 to move to the right. The first transmission gear 1117 moves to the right. The worm 92 moves to engage with the second transmission gear 1118, thereby driving the worm 92 to rotate and drive the second transmission gear 1118 in front to rotate, the second transmission gear 1118 in front to rotate and drive the first transmission gear 1117 in front to rotate, the first transmission gear 1117 in front to rotate and drive the limiting cross bar 1115 to rotate, the limiting cross bar 1115 rotates and drives the first transmission gear 1117 at the rear to rotate, the first transmission gear 1117 at the rear to rotate and drive the second transmission gear 1118 at the rear to rotate, the second transmission gear 1118 at the rear to rotate and drive the first transmission short shaft 1111 at the bottom to rotate, the first transmission short shafts 1111 on the upper and lower sides rotate and cooperate to drive the positioning belt assembly 1110 to rotate, the positioning belt assembly 1 The rotation of 110 drives the positioning short rod 1112 to rotate, the rotation of the positioning short rod 1112 drives the L-shaped lifting frame 113 to move upward, the upward movement of the L-shaped lifting frame 113 drives the connecting long column 112 to move upward, the upward movement of the connecting long column 112 drives the charging hopper 111 to move upward, the upward movement of the charging hopper 111 drives the lifting slider 116 to move upward, the maximum upward movement stroke of the lifting slider 116 is limited by the fixed base 1, and then the charging hopper 111 continues to move upward and starts to swing upward through the sliding short column 115, the first return spring 119 is compressed, and the charging hopper 111 swings upward to pour cement into the processing bottom cylinder 7, so that the positioning belt assembly 1110 continues to rotate through the positioning short rod 11 12 drives the L-shaped lifting frame 113 to move downward and reset. Due to the action of the first reset spring 119, the loading hopper 111 swings downward and resets. The L-shaped lifting frame 113 moves downward and drives the loading hopper 111 to move downward and reset. At the same time, the first photoelectric sensor 1119 detects the corresponding material of the processing bottom barrel 7 through the transparent observation window. The first photoelectric sensor 1119 sends a signal. After receiving the signal, the control module controls the telescopic rod of the electric push rod 1113 to retract. The positioning connecting block 1114 drives the first transmission gear 1117 to move to the left and reset through the limiting cross bar 1115. The first transmission gear 1117 moves to the right and disengages from the second transmission gear 1118. In this way, it is convenient for people to pour cement.

[0049] When the lifting slide block 116 moves upward, the lifting slide block 116 moves upward to drive the driving rack 121 to move upward, and the driving rack 121 moves upward to mesh with the first driven gear 122, and the driving rack 121 causes the first driven gear 122 to reverse, and the reversal of the first driven gear 122 drives the second transmission short shaft 123 to reverse, and the reversal of the second transmission short shaft 123 drives the transmission belt assembly 124 to reverse, and the reversal of the transmission belt assembly 124 drives the third transmission short shaft 125 to reverse, and the reversal of the third transmission short shaft 125 drives the positioning gear 126 to reverse, and the reversal of the positioning gear 126 drives the driven rack 127 to move left, and the driven rack 127 moves left to drive the feeding ramp 128 to move left, so that the loading hopper 111 swings upward to pour cement into the processing bottom cylinder 7 through the feeding ramp 128. Similarly, the lifting slide block 116 drives the driving rack 121 to reset downward, and the feeding ramp 128 also moves to the right and resets, so that it can be avoided that the cement is difficult to pour into the processing bottom cylinder 7.

[0053] First, the operator connects a water pipe to the water inlet of the water pump 132. When the device is powered on, the pressure sensor 136 starts to work, and the L-shaped lifting frame 113 moves upward to disengage from the pressure sensor 136. The pressure sensor 136 sends a signal. After receiving the signal, the control module controls the water pump 132 to work, and the water pump 132 pumps clean water into the buffer cylinder 131. The liquid level sensor 133 monitors the water level in the buffer cylinder 131.
