After the connecting rod is arranged at one end of the base and the sliding block is slidingly installed in the inner part of the sliding groove, the driving electric lead screw drives the sliding block to move, so that the connecting rod rotates, and then the one end of the base is lifted upward, so that the materials in the inner part of the main body slide to one side, the residual materials in the inner part of the main body can be effectively prevented from affecting the drying use of subsequent materials, and the overall practicality is improved. After one end of the sleeve pipe is arranged outside the discharge port of the main body, the dust raised in the inner part of the sleeve pipe can be sucked out through the air pump outside the dust collecting pipe, and then the dust particles are filtered by the filter screen and guided outward, and finally slide into the inner part of the storage box for storage, so that the subsequent cleaning use is facilitated, and the structure is simple and can effectively prevent dust from spreading everywhere and affecting the environment.
[0004] However, the entering port of the storage box is too small, so that all the dust filtered by the filter screen cannot be collected, and a considerable part of the dust flows back to the inner part of the main body. UTILITY MODEL CONTENTS
