Problems solved by technology

[0002] A large number of stones are used in the construction of water conservancy projects, and there are often some cracked and unusable bricks or large crushed stones. At present, these bricks or crushed stones are generally used as landfills. Buried in the recess for processing, but large pieces of crushed stone need to be crushed, the crushing efficiency of the existing crushing device is not high, at the same time, a large amount of crushed stone enters the crushing device, if the crushing device cannot be crushed in time, it will cause blockage, further reducing the Crushing efficiency

Abstract

The invention discloses a stone crushing device for hydraulic engineering. The device comprises a bottom plate and a crushing box, wherein a feeding hopper is connected to one side of the crushing box, a stone crushing assembly is arranged in the crushing box, the stone crushing assembly comprises a vibration plate, crushing teeth, a fixing frame, a fixing plate, sleeve rods, sleeves, first damping springs, a connecting rod, a double-shaft motor, swing blocks and an extrusion plate, the two swing blocks are fan-shaped blocks and are symmetrically installed at the two output ends of the double-shaft motor, the top of the double-shaft motor is hinged to the fixing plate through a connecting rod, one ends of the plurality of sleeve rods are fixedly installed at the upper portion of the fixingplate, the other ends of the sleeve rods are movably arranged in the sleeves in a sleeved mode, the first damping springs are arranged between the other ends of the sleeve rods and the sleeves, the sleeves are arranged at the top of the crushing box, the vibration plate is installed below the swing blocks through the fixing frame, the extrusion plate is located below the feeding hopper and the vibration plate and fixed to the side wall of the crushing box, and the crushing teeth are fixedly arranged on the extrusion plate and the vibration plate. By arranging the crushing assembly, the crushing efficiency is improved, and the device is prevented from being blocked in the feeding process.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a stone crushing device for water conservancy engineering. Background technique [0002] A large number of stones are used in the construction of water conservancy projects, and there are often some cracked and unusable bricks or large crushed stones. At present, these bricks or crushed stones are generally used as landfills. Buried in the recess for processing, but large pieces of crushed stone need to be crushed, the crushing efficiency of the existing crushing device is not high, at the same time, a large amount of crushed stone enters the crushing device, if the crushing device cannot be crushed in time, it will cause blockage, further reducing the crushing efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a stone crushing device for water conservancy engineering, so as to solve the problems raised in the above-me...
