Aggregate crushing and conveying device for construction

Abstract

The invention discloses an aggregate crushing and conveying device for construction. The aggregate crushing and conveying device comprises a multi-stage crushing and screening device. According to theaggregate crushing and conveying device, a screening mechanism is arranged inside a crushing frame, during swinging of a second crank, a second movable rod is driven to swing, the second movable roddrives a swing plate to swing accordingly, and a screening screen screens aggregates, so that the small aggregates are discharged through the bottom of the screening screen, and the large aggregates are discharged to the inner side of a secondary crushing mechanism for secondary crushing to achieve the advantage of rapid screening of the aggregates; and the secondary crushing mechanism is arrangedin the crushing frame, a rotary disc rotates and drives a belt pulley to rotate through a driving belt, so that the belt pulley drives a first sliding block to reciprocate up and down, and the firstsliding block drives a second sliding block to move left and right through a second connecting handle, so that the second sliding block drives a broken toothed plate to reciprocate back and forth on the inner side of a diversion baffle through a receiving rod to conduct secondary crushing on the discharged aggregates, and the advantage of secondary crushing of the aggregates is achieved.

Description

technical field [0001] The invention relates to related fields of construction processing, in particular to a construction aggregate crushing and conveying device. Background technique [0002] Aggregate is also called "aggregate". It is a granular material that acts as a skeleton and filling in concrete and mortar. There are two types of fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5mm. Generally, natural sand is used. Such as river sand, sea sand and valley sand, etc., when there is a lack of natural sand, artificial sand ground from hard rocks can also be used; the diameter of coarse aggregate particles is greater than 5mm, and gravel and pebbles are commonly used. The strength of concrete is higher than that of pebble concrete, but crushed stone is made of crushed rocks, and the cost is higher than that of pebbles. Coarse aggregates commonly used in lightweight aggregate concrete include pumice and other natural porous...

Problems solved by technology

[0003] In the process of construction engineering, it is often necessary to crush and convey aggregates. At this time, aggregate crushing and conveying devices are needed. The current aggregate crushing and conveying devices are generally simple in structure and can only perform simple aggregate crushing. Crushing and conveying, but because the aggregate conveying speed is too fast, the aggregate is often broken unevenly. At this time, the aggregate often needs to be crushed multiple times. The existing aggregate crushing and conveying equipment is not easy to perform multi-stage crushing and screening of the aggregate. lead to uneven crushing of the aggregate
