The invention discloses an automatic wall
grinding device for building decoration, which comprises a scissor-type lift frame and a
grinding mechanism installed on the top of the scissor-type lift frame. A storage groove is arranged in the right end surface of the
grinding mechanism, and the storage groove is slidably fitted. An airtight sleeve is connected, and a grinding chamber is provided in the airtight sleeve. A transmission chamber is provided in the grinding mechanism on the left side of the
storage tank. A first partition is provided between the transmission chamber and the
storage tank. The driving chamber is provided with a second partition between the driving chamber and the transmission chamber, the bottom wall of the transmission chamber is provided with a first sliding groove, and the connecting rods extending toward the left and right sides are slidably connected in the first partition, The extension section on the right side of the connecting rod extends into the
storage tank and extends into the grinding chamber through the airtight sleeve. The right extension end of the connecting rod is fixed with a support plate, and the connecting rod is provided with a first through hole extending left and right; the structure of the present invention Simple, reasonable design, high airtight effect, prevents dust from flying, can reduce occupied space, and has low manufacturing and maintenance costs.
