The lifting bucket 1 rotates to scoop up the concrete raw materials at the bottom for transportation, and the concrete raw materials rotate to the top of the transmission belt to be dumped onto the inclined plate. After dumping, the electric push rod drives the inclined plate to move away from the lifting bucket 1 to facilitate the rotation of the lifting bucket 1. The lifting bucket 1 drives the first scraper 2 to move, and the first scraper 2 drives the push rod 3 to move gradually close to the arc plate 4. The arc plate 4 pushes the push rod 3 to move, and the push rod 3 drives the first scraper 2 to move The inner wall of the lifting bucket 1 is cleaned by the first scraper 2. When the first scraper 2 is worn and cannot fit with the inner wall of the lifting bucket 1, the extrusion mechanism pushes the second scraper 5 to move and fit with the inner wall of the lifting bucket 1 again to clean its surface, thereby reducing the adhesion of concrete raw materials on the inner wall of the lifting bucket 1, reducing the load when the lifting bucket is idling, and increasing the carrying capacity of the lifting bucket. When the lifting bucket 1 shovels the concrete raw materials at the bottom, the concrete raw materials push the first scraper 2 to move and gradually slide into the lifting bucket 1 for reset. The first scraper 2 drives the second scraper 5 to slide and reset through the extrusion mechanism.

[0026] The inner cross-section of the opening of the lifting bucket 1 is an isosceles trapezoid and the opening spacing gradually increases along the outlet end.

[0029] Please combine Figure 1 As shown, during use, when the first scraper 2 slides repeatedly and becomes worn, the compression spring 9 pushes the dovetail block 8 to move, and the dovetail block 8 drives the second scraper 5 to move and clean the inner wall of the lifting bucket 1, thereby reducing the adhesion of concrete raw materials on the inner wall of the lifting bucket 1.

[0030] The push rod 3 has a trapezoidal cross section and the cross section of the end away from the lifting bucket 1 is an arc surface.

[0031] Please combine Figure 1 As shown, during use, the contact area between the push rod 3 and the arc plate 4 is reduced, thereby reducing the friction between the push rod 3 and the arc plate 4, which facilitates the sliding of the push rod 3.

[0032] The push rod 3 is rotatably embedded with a roller 10 at the end away from the lifting bucket 1 , and the roller 10 can fit the surface of the arc plate 4 .

[0033] Please combine Figure 1 As shown, during use, the lifting bucket 1 indirectly drives the push rod 3 to rotate, and the push rod 3 drives the roller 10 to rotate and fit with the surface of the arc plate 4. The arc plate 4 pushes the roller 10 to move and causes the roller 10 to rotate. The roller 10 pushes the push rod 3 to move, and the push rod 3 pushes the first scraper 2 to move. The arc plate 4 pushes the roller 10 to rotate, so that rolling friction is formed between the arc plate 4 and the roller 10, which facilitates the rotation of the push rod 3.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
