[0025] In this embodiment: when the motor 701 is powered on and running, the output shaft of the running motor 701 drives the turntable 702 to rotate. The rotating turntable 702 drives the eccentric rod 703 to rotate, which in turn drives the connecting rod 704 to move.

[0026] Please refer to this carefully. Figure 4 The other end of the connecting rod 704 is rotatably connected to the connecting seat 707, and the moving connecting rod 704 is used to drive the impact block 706 to reciprocate through the connecting seat 707.

[0027] In this embodiment: the moving link 704 drives the impact block 706 to move through the connecting seat 707, and the impact block 706 reciprocates along the outer wall trajectory of the guide rod 705.

[0028] Please refer to this carefully. Figure 2 The impact block 706, which is moving towards the support frame 1, is used to impact and vibrate the surface of the aggregate bin 2.

[0029] In this embodiment, the impact block 706, which is moving towards the support frame 1, impacts and vibrates the surface of the aggregate bin 2, causing the residual concrete aggregate adhering to the inner wall of the aggregate bin 2 to be shaken off.

[0030] Please refer to this carefully. Figure 3 The scraper mechanism 6 includes a cylinder 601, a lifting rod 602 and a scraper 603;

[0032] In this embodiment: When the cylinder 601 is powered on, the output end of the cylinder 601 in operation drives the lifting rod 602 to move up and down. The lifting rod 602 in the lifting state drives the scraper 603 to move up and down. The scraper 603 in the lifting state scrapes off the residual concrete aggregate adhering to the inner wall of the aggregate bin 2. Thus, the above structure avoids the situation where residual concrete aggregate easily adheres to the inner wall of the aggregate bin 2.

[0033] Please refer to this carefully. Figure 3 The output end of the cylinder 601 in the energized state is used to drive the scraper 603 to move up and down through the lifting rod 602, and the scraper 603 in the lifting state is used to scrape off the residual concrete aggregate adhering to the inner wall of the aggregate bin 2.

[0035] Working principle: First, the motor 701 is powered on and started, so that the output shaft of the running motor 701 drives the turntable 702 to rotate. The rotating turntable 702 drives the eccentric rod 703 to rotate, which in turn drives the connecting rod 704 to move. The moving connecting rod 704 drives the impact block 706 to move through the connecting seat 707. The impact block 706 then moves back and forth along the outer wall trajectory of the guide rod 705. The impact block 706, which is moving towards the support frame 1, impacts and vibrates the surface of the aggregate bin 2, vibrating off the residual concrete aggregate adhering to the inner wall of the aggregate bin 2.

[0036] Then, the cylinder 601 is powered on and operated, so that the output end of the cylinder 601 in operation drives the lifting rod 602 to move up and down. The lifting rod 602 in the lifting state drives the scraper 603 to move up and down. The scraper 603 in the lifting state scrapes off the residual concrete aggregate adhering to the inner wall of the aggregate bin 2. Thus, the above structure avoids the situation where residual concrete aggregate easily adheres to the inner wall of the aggregate bin 2.
