The bracket 4 is welded at the upper positions of the front surface and the back surface of the hopper 2, and the case 11 is installed at the top of the bracket 4.

The utility model discloses a theory of operation is:

when the automatic cleaning device is used, when the inner wall of the hopper 2 does not need to be cleaned, the electric telescopic rod 6 is shortened to move the first scraper 7 and the second scraper 10 out of the hopper 2, the transverse moving driving component 5 moves the displacement plate 8 to the rightmost side, and at the moment, no shielding object exists at the opening at the top of the hopper 2;

when the inner wall surface of the hopper 2 needs to be cleaned, the hopper 2 is cleaned firstly from the left side and then is gradually pushed to the right side, so that the phenomenon that the cleaning assembly is damaged due to overlarge stress caused by directly cleaning from the right side in the hopper 2 and more asphalt is cleaned at one time is avoided, and the stability and the durability of the operation of the device are ensured;

the principle is as follows:

after the displacement plate 8 is moved to the indicating position by the two transverse moving driving components 5, the electric telescopic rod 6 drives the displacement plate 8 to descend, so that the front and the back of the inner wall of the hopper 2 are cleaned by the two scrapers I7 respectively, after the scrapers II 10 are contacted with the bottom inside the hopper 2, the transverse moving driving components 5 drive the displacement plate 8 to move towards the discharge port of the hopper 2, so that the asphalt cleaned from the inner wall is cleaned out from the inside of the hopper 2, and the scrapers II 10 can also clean the right side of the inner wall of the hopper 2;

the driving principle of the traverse driving assembly 5 is as follows: the driving motor 12 drives the threaded rod 16 to rotate through the belt-type transmission member 18, that is, the driving motor 12 can drive the threaded rod 16 to rotate in a forward direction and a reverse direction in a switching manner, and under the screw transmission action of the driving plate 15 and the threaded rod 16, the threaded rod 16 can drive the displacement plate 8 to move transversely, so as to drive the first scraper 7 and the second scraper 10 to move transversely.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
