Efficient energy-saving sand making device

Abstract

The invention discloses an efficient energy-saving sand making device. The efficient energy-saving sand making device comprises a mounting frame and connecting pieces, a material conveying hole is formed in the middle of the mounting frame, and electric hydraulic push rods are fixedly connected to the positions, close to the two ends, of the middle of the upper surface of the mounting frame through bolts. According to the efficient energy-saving sand making device, the two electric hydraulic push rods above the mounting frame are started through a controller, so that the electric hydraulic push rods drive fixing blocks to drive the connecting pieces, positioning pieces and limiting pieces to periodically move back and forth in a mounting box in a staggered mode, and therefore, stones entering the connecting pieces, the positioning pieces and the limiting pieces can be effectively crushed and ground through sloping grain blocks; and the input stones can be effectively further crushed and ground through the stepped design of the width sizes of the connecting pieces, the positioning pieces and the limiting pieces, so that the input stones are effectively ground and crushed with the maximum efficiency, the high efficiency of stone sand making is powerfully improved, the operation intensity of a user is reduced, and the complicated technological process is reduced.

Description

technical field [0001] The invention relates to the technical field of sand making devices, in particular to a high-efficiency and energy-saving sand making device. Background technique [0002] Sand making machine is a mechanical equipment that grinds and breaks larger stones until the stone is ground and broken to the required particle size. Sand making machine is widely used in large, smelting, building materials, roads, railways, water conservancy and chemical industries. and many other departments, and the sand making device in the prior art still has many deficiencies when grinding and crushing stone materials, for example: [0003] The sand-making device in the prior art is difficult to effectively realize the effect of integrated and gradually refined sand-making when grinding and crushing stone materials, so that the stones under the particles of various sizes need to be ground and crushed in multiple grinding stages. Grinding is carried out in the equipment under ...

Problems solved by technology

[0003] The sand-making device in the prior art is difficult to effectively realize the effect of integrated and gradually refined sand-making when grinding and crushing stone materials, so that the stones under the particles of various sizes need to be ground and crushed in multiple grinding stages. Grinding is carried out in the equipment under the dimensional accuracy, and at the same time, the transfer process in each equipment has high energy consumption and inconvenient operation, so it cannot meet the needs of the existing technology
