Fast and efficient sand making machine

Abstract

The invention discloses a fast and efficient sand making machine comprising a sand making machine body; the upper end of the interior of the sand making machine body is provided with a gear crushing disc; the middle portion of the upper surface of the gear crushing disc is provided with a tapered material groove penetrating through the bottom surface; a clapboard is fixedly arranged in the interior of the sand making machine body and located below the gear crushing disc; the middle portion of the upper surface of the clapboard is fixedly provided with a guide grinding rod; the inner side surfaces of drive gear shafts are both meshed with the outer side surface of the gear crushing disc; the inner side surfaces of driving gear shafts are both meshed with the outer side surface of the outerside surfaces of the drive gear shaft; the outer side end of the lower surfaces of fixed discs are provided with annular limiting grooves; and loop-shaped sliding plates are arranged in the annular limiting grooves in an inserting mode. In the process of grinding crushed stones into sand, particle sizes of the crushed stones are reduced first, and bad feeding and clogging of a grinding disc causedby the large particle sizes of crushed stones during milling is prevented; and the arrangement of the loop-shaped sliding plates increases the contact surface between a milling disc and the crushed stones when grinding the grinding disc, and the efficiency of the crushed stone grinding is improved.

Description

technical field [0001] The present invention relates to the technical field of sand making equipment, and more specifically relates to a fast and efficient sand making machine. Background technique [0002] In the field of mining equipment, the vertical shaft impact crusher is also known as the sand making machine. Its working principle is to divide the material into the throwing material in the middle and the blanking material in the surrounding area. It is thrown at high speed and collides with the surrounding falling materials, and the stones are broken by the "rock-on-rock" method, and then ground into sand. When working, the material enters the interior of the rotor from the feed port above the rotor group, and is centrifugally thrown out with the rotation of the rotor group; Large, it is easy to cause the rotor group to discharge unsmoothly, affecting the material throwing, and when the traditional sand making machine grinding disc is grinding, the contact surface wit...

Problems solved by technology

When working, the material enters the interior of the rotor from the feed port above the rotor group, and is centrifugally thrown out with the rotation of the rotor group; Large, it is easy to cause the rotor group to discharge unsmoothly, affecting the material throwing, and when the traditional sand making machine grinding disc is grinding, the contact surface with the gravel is small, which leads to the reduction of the crushing efficiency of the sand making machine. For this reason, We propose a fast and efficient sand making machine
