[0028] Working principle:

[0029] Feed port 4 adjustment process:

[0030] When cement gravel needs to be transported, in order to prevent the feed port from being blocked, the external power supply of the second motor 202 is turned on and started, and the second motor 202 drives the protrusion 203. When the protrusion 203 contacts the slider 204, the protrusion 203 drives the slider 204 to move upward (such as Figure 3 ), when the slider 204 moves upward, the triangular block 205 is driven to move rightward through the mixing belt, at this time the spring 206 is stretched, the triangular block 205 drives the plate 207 to move rightward in the feed port 4, the plate 207 moves to adjust the size of the feed port 4, and the second motor 202 is turned off after the plate 207 moves to a suitable position;

[0031] When the second motor 202 drives the protrusion 203 to rotate and separate from the slider 204, the spring 206 rebounds and drives the plate 207 to reset according to the above method. At the same time, the slider 204 slides downward. When the protruding part of the surface of the slider 204 fits with the first shell 201, the slider 204 stops moving downward (such as Figure 3 ), thereby limiting its position, and adjusting the size of the feed opening 4 in the above manner so that it will not be blocked during feeding.

[0032] Cement stabilized gravel conveying process:

[0033] The worker introduces the cement-stabilized gravel into the transmission barrel 1 through the adjusted feed port 4, and at the same time connects the external power supply of the first motor 5 and starts it. The first motor 5 drives the column 7 to rotate in the disc 6, and the main body 7 drives the conveying screw 8 to rotate. The conveying screw 8 conveys the cement-stabilized gravel in the transmission barrel 1. The conveying screw 8 drives the cement-stabilized gravel in the transmission barrel 1 to move to the next process through the right end of the transmission barrel 1. After the cement-stabilized gravel is transported, the first motor 5 is turned off, and the conveying of the cement-stabilized gravel is completed in the above manner.

[0034] Disassembly process;

[0035] The bolt on the left end of the transmission cylinder 1 can be rotated to cancel the fixation to the disc 6, and then the disc 6 can be removed from the transmission cylinder 1, and the first motor 4, the column 7 and the conveying screw 8 are removed together. The bolts on the surface of the column 7 can be turned to cancel the fixation to the output shaft side of the first motor 4, and the conveying screw 8 can be removed from the output of the first motor 4. The parts can be maintained in the above manner.

[0036] Vibration process:

[0037] The external power supply of the two third motors 302 is turned on and started, and the two third motors 302 respectively drive the second gear 304 to rotate, and the second gear 304 drives the first gear 303 to rotate in the opposite direction, and the first gear 303 and the second gear 304 rotate relative to each other, and the protruding parts on the surface respectively drive the connecting rod 305 to move, and the connecting rod 305 drives the first block 306 to move rightward through the pin shaft (such as Figure 6 ), the first block 306 drives the second block 307 to move, and the second block 307 moves to knock and vibrate the surface of the transmission cylinder 1. According to the above method, the third motor 302 continues to rotate to drive the second block 307 to reset. Through the above method, the second block 307 reciprocates to knock and vibrate the transmission cylinder 1, and vibrates the cement-stabilized gravel remaining in the transmission cylinder 1, so that it flows out with the inclination of the transmission cylinder 1. After the remaining cement-stabilized gravel flows out with the inclination of the transmission cylinder 1, the third motor 302 is turned off, and the cleaning work of the remaining cement-stabilized gravel in the transmission cylinder 1 is completed in the above method.
