Crushed stone processing equipment for bridge engineering construction

Abstract

The invention discloses macadam processing equipment for bridge engineering construction. The macadam processing equipment comprises a shell, a crushing chamber, an extrusion conveying chamber and a rolling chamber, wherein the crushing chamber is arranged at the upper right side of the shell, a feeding inlet is arranged at the left side of the top of the crushing chamber, and the crushing chamberis in communication with the feeding inlet; the extrusion conveying chamber is obliquely located at the bottom of the right side of the shell, the right side of the top of the extrusion conveying chamber is in communication with the right side at the bottom of the crushing chamber, the rolling chamber is located on the left side of the bottom of the shell, the left side of the extrusion conveyingchamber is in communication with the rolling chamber, and a second working motor is located on the top of the rolling chamber; a first connecting rod is welded on the left side of the second workingmotor, a vertical guide rail is fixedly welded at the upper part of the left side wall of the rolling chamber, and the left end of the first connecting rod extends into the vertical guide rail. The macadam processing equipment has high working efficiency, saves time and labor, and can carry out multi-stage pulverization on stones and lower the difficulty of crushing stones.

Description

technical field [0001] The invention relates to the technical field of bridge engineering equipment, in particular to crushed stone processing equipment for bridge engineering construction. Background technique [0002] Bridge engineering mainly studies the design of bridge crossings, determines the bridge aperture, considers navigation and route requirements to determine the height of the bridge deck, considers that the base will not be scoured or frost heaved to determine the foundation embedding depth, and designs diversion buildings, etc.; bridge scheme design ; Bridge structure design; Bridge construction; Bridge verification; Bridge test; Bridge maintenance, etc. [0003] Crushed stone is a common material used to lay the foundation bed of bridges. In bridge construction, crushed stones are used to pave the base. For different bridge grade requirements, the size of crushed stones is also different. At this time, we will use different sizes The crushed stones are crush...

Problems solved by technology

The hammer crusher currently used in the market smashes the stone through the high-speed rotating hammer head, the stone particles are uneven, and the hammer crusher is noisy, poor in stability, complex in structure, cumbersome in operation, and Some crushing machines overturn the crushed stones at one time after the crushing is completed, and cannot accurately control the amount of pouring required for construction, resulting in waste and increased cleaning workload, which is inefficient; and the crushed stones of different sizes are fully processed. If they are mixed together, they will affect the construction quality of the bridge and ultimately affect the service life of the bridge.
