[0028] As a further implementation of the application, the corrugated folding plate 28 arranged in the inner side of each anti-falling groove 27 is provided with two, the two corrugated folding plates 28 are symmetrically arranged left and right, one end of the corrugated folding plate 28 is fixedly connected to the top of the inner side of the guide box 22, and the other end of the corrugated folding plate 28 is fixedly connected to the outer side of the adjusting seat 23, which effectively prevents the materials generated in the cleaning process from entering the inner side of the guide box 22.
[0029] As a further implementation of the application, one side of one of the adjusting seats 23 is fixedly installed with a first motor 2301 through a motor seat, a transmission shaft of the first motor 2301 penetrates the inner side of the adjusting seat 23, and one end of the installation rod 24 is fixedly connected with the transmission shaft of the first motor 2301, so that the first motor 2301 provides power for the rotation of the installation rod 24.

[0033] Work flow: The installation frame 1 is provided with installation holes at four corners, and the installation frame 1 is fixed below the crushing end of the crusher through cooperation of external bolt and nut groups. In order to protect the installation rod 24 and the rotating mechanism 26 from damage during the operation of the crusher, the installation rod 24 together with the rotating mechanism 26 is placed below the arc-shaped protective plate 4. The upper surface of the arc-shaped protective plate 4 is designed in an arc-shaped structure, so that the falling materials can slide forward along the arc surface and the falling plate 5, thereby avoiding direct impact of the materials on the installation rod 24, and achieving a good protection effect.
[0034] When it is necessary to clean the self-cleaning screen assembly 2, the first motor 2301 and the second motor 2902 are started. The transmission shaft on the placing seat 2901 drives the transmission screw rod 29 to rotate. Since the adjusting seat 23 is in threaded connection with the transmission screw rod 29, the adjusting seat 23 moves along a predetermined path in the guide box 22 as the transmission screw rod 29 rotates. In this process, the adjusting seat 23 pushes the corrugated folding plate 28 to stretch and contract, effectively preventing the materials generated during the cleaning process from entering the inside of the guide box 22, and ensuring that the transmission screw rod 29 can run smoothly. Meanwhile, the movement of the adjusting seat 23 also drives the installation rod 24 to move synchronously. The first motor 2301 drives the installation rod 24 to rotate through the transmission shaft thereof. At this time, the cleaning brush 266 (soft in texture) and the cleaning steel wire brush 267 (hard in texture) installed on the installation rod 24 are respectively responsible for removing dust and larger particles, and the two brushes complement each other to improve the overall cleaning efficiency. In addition, in order to ensure that the two brushes are always closely attached to the surface of the self-cleaning screen assembly 2, the reset spring 264 in the installation cavity 263 provides upward elastic support, which is transmitted to the two brushes (the cleaning brush 266 and the cleaning steel wire brush 267) through the push plate 265, so that the two brushes can maintain a good contact state throughout their service life, thereby achieving a continuous and effective cleaning effect.
[0035] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
