[0005] Preferably, the material distributing pipe is connected to the feeding pipe through an elastic bellows, the outer wall of the material distributing pipe is hingedly connected with a telescopic rod, and the fixed end of the telescopic rod is hingedly connected to the lower surface of the cover plate. The arrangement here can adjust the inclination angle of the material distributing pipe by extending and contracting the telescopic rod, thereby adjusting the position of the material distributing port of the material distributing pipe, further expanding the range of material distributing.

[0006] Preferably, the telescopic rod is an electric push rod or a hydraulic rod, and the rotating motor is a forward and reverse motor. The forward and reverse motor periodically drives the cover plate to rotate forward and reverse, and when the connecting line of the telescopic rod is long enough, the normal use of the telescopic rod is ensured.

[0007] Preferably, an exhaust pipe is provided on the material receiving box above the screen, and the exhaust pipe can be connected to a bag dust collector to discharge the gas in the material receiving box and collect and reuse the materials contained in the bag dust collector.

[0008] Preferably, the screen is a vibrating screen, and a cleaning port is provided on the side wall of the receiving box corresponding to the screen, which improves the screening efficiency and can also clean the upper surface of the screen to avoid affecting the next screening effect.

[0009] Preferably, the crusher is a double-roll crusher.

[0011] Working principle: the material crushed by the crusher enters the feed pipe through the discharge pipe, the forward and reverse motor drives the driving gear to rotate forward and reverse periodically, and the cover plate rotates forward and reverse synchronously under the action of the rack and the driving gear. The material entering the feed pipe is discharged from the inclined distribution pipe and falls on the screen, which makes the distribution track of the distribution pipe on the screen circular. In the above distribution process, the distribution track can be further adjusted by controlling the extension and retraction of the telescopic rod and adjusting the inclination angle of the distribution pipe, thereby increasing the distribution range of the distribution pipe, making the material falling on the screen more uniform, further improving the screening effect and screening efficiency, reducing the impact of the material on the same point of the screen, and increasing the service life of the screen.
