[0014] The present invention provides a device for forming ceramsite powder into balls, which has the following beneficial effects:

[0015] (1) The invention drives the reciprocating screw to rotate by the rotation of the motor, and the rotation of the reciprocating screw drives the stirring rod to rotate. The ceramsite powder and additives are stirred by the rotation of the stirring rod, so that the ceramsite powder and additives are fully mixed together. At the same time, the scraper moves downward to scrape the inner wall of the mixing drum to prevent the ceramsite powder and additives from adhering to the inner wall of the mixing drum and affecting subsequent feeding. The short rod moves away from the inner wall of the mixing drum to drive the elastic telescopic plate and the scraper to separate from the inner wall of the mixing drum, preventing them from contacting the inner wall of the mixing drum for a long time, resulting in a reduction in the service life of the scraper.

[0016] (2) In the present invention, the circular hole of the rotating plate will overlap with the discharge port during rotation, and the overlap allows the ceramsite powder to intermittently enter the mixing drum, preventing continuous entry that results in uneven mixing of the ceramsite powder and additives. The mixing effect can be improved by intermittent entry combined with stirring with a stirring rod. At the same time, the ceramsite powder inside the feed port can be stirred by the rotation of the rotating plate, preventing the ceramsite powder from getting stuck in the feed port, causing blockage of the feed port and affecting the feeding effect.

[0017] (3) In the present invention, the push block moves toward the direction close to the feed port to push the connecting rotating plate to rotate, and the rotation of the connecting rotating plate drives the scraper to rotate. The rotation of the scraper drives the surface of the rotating nozzle to be scraped, so as to prevent the entering expanded clay powder from blocking the rotating nozzle and prevent the additives in the water tank from being effectively sprayed out, thereby affecting the mixing effect. At the same time, the rotating nozzle can switch the spraying range, making the spraying range wider, improving the spraying effect, and improving the mixing effect of expanded clay powder and additives.
