Description

Recovery unit is smashed to building engineering construction waste material

Technical Field

The invention relates to the field of building construction, in particular to a crushing and recycling device for construction waste of building engineering.

Background

In the building work progress, often can produce more building waste and rubbish, like dumped timber etc. most building waste and rubbish are not handled any, just by arbitrary landfill, stack of construction unit, not only cause the influence to the environment, extravagant renewable energy simultaneously, in order to solve above problem, at present, many enterprises smash back recycle to building waste.

The construction waste rubbing crusher that the enterprise used usually includes crushing barrel and the pivot of setting in crushing barrel, and it is rotatory to drive the pivot through the motor, and the pivot will drive the epaxial crushing blade rotation of commentaries on classics, and crushing blade will smash the material. When this kind of rubbing crusher is used for the smashing of construction waste or rubbish, because there is some plastic bags or rope in the construction waste, plastic bags or rope etc. twine easily in the pivot when the pivot is rotatory, cause the pivot load to aggravate, can lead to the motor to burn even when serious, bring serious safety problem and unnecessary loss of property.

Disclosure of Invention

The invention aims to provide a waste crushing and recycling device for construction engineering, which aims to solve the problem that materials are wound around a rotating shaft when the waste is crushed.

In order to achieve the purpose, the invention adopts the following technical scheme:

a crushing and recycling device for construction engineering construction waste comprises a crushing barrel, wherein a rotating shaft is connected in the crushing barrel in a rotating mode, crushing blades are arranged on the rotating shaft, the rotating shaft is hollow, a plurality of groups of anti-winding assemblies are arranged on the outer wall of the rotating shaft, the anti-winding assemblies are distributed along the circumferential direction of the rotating shaft, each group of anti-winding assemblies comprises a plurality of protection plates attached to the outer side wall of the rotating shaft, the protection plates in each group of anti-winding assemblies are distributed along the axial direction of the rotating shaft, one end of each protection plate is rotatably connected to the outer wall of the rotating shaft, the other end of each protection; sliding connection has magnet in the pivot, still is equipped with the cutter that can inhale mutually with magnet on the pivot outer wall, and the cutter is located the antiwind subassembly outside, and the cutting edge of cutter can pass between the link and the free end of antiwind subassembly.

The principle of the scheme is as follows:

the rotation of pivot drives the epaxial crushing blade rotation of commentaries on classics, thereby smash the building waste in the crushing barrel, there are easy windings such as plastic bag or rope in the building waste and changeing epaxial winding, antiwind subassembly is used for preventing that the winding is direct to be twined in the pivot, the winding can separate antiwind subassembly winding in the pivot when the pivot is rotatory, smash the completion back, discharge building waste outside the crushing barrel, the winding still separates antiwind subassembly winding in the pivot this moment, opening mechanism is arranged in driving each screening glass free end among the antiwind subassembly and opens in proper order, screening glass free end and pivot outer wall produce a gap, strut the winding, can drive the cutter that attracts mutually with magnet during the magnet motion along pivot axial motion, the winding that can strut the screening glass free end during the cutter motion cuts.

This scheme of adoption can reach following technological effect:

1. the magnet in the rotating shaft drives the cutter to move on the outer wall of the rotating shaft, so that the winding on the rotating shaft can be scratched, and the problem that the winding is always remained on the rotating shaft to cause the load of the rotating shaft to be aggravated is avoided.

2. Because the cutter opens through the screening glass free end and props up the winding when cutting the winding, the cutter cuts the winding of the gap department between screening glass free end and the pivot outer wall, and not the cutter directly supports the pivot outer wall and cuts the winding, consequently the cutter can not fish tail the pivot outer wall when cutting the winding of winding in the pivot.

3. When the free end of the protection plate supports the winding, the winding at the free end of the protection plate can be stretched, so that the winding at the free end of the protection plate becomes thin or thinned, and the winding at the free end of the protection plate is easier to cut by the cutting knife.

Further, the mechanism that opens includes the actuating lever of sliding connection in the pivot, and the actuating lever includes coaxial fixed connection's cylinder portion and circular cone portion, cylinder portion and magnet fixed connection, and the actuating lever extends along the axial of pivot, and the screening glass is fixed with the dwang with the one end that the pivot is connected, and the dwang is located the pivot, and the dwang is perpendicular with the axis of pivot, even has the piece that resets between dwang and the pivot inner wall, and the lateral wall of dwang can offset with the actuating lever lateral wall. The magnet vertically moves in the rotating shaft to drive the driving rod fixedly connected with the magnet to move, after the side wall of the conical part of the driving rod is abutted against the side wall of the rotating rod, the diameter of the conical part is gradually increased, the rotating rod is driven to rotate, so that the protection sheet is driven to rotate, and the free end of the protection sheet is opened; the movement of the magnet in the rotating shaft is used as power to drive the protection plates to be opened in sequence, and extra power is not needed to drive the protection plates to be opened.

Further, still be equipped with the mechanism of blowing in the pivot, the mechanism of blowing includes the piston cylinder of fixed connection in crushing barrel bottom and the piston of sliding connection in the piston cylinder, piston and magnet fixed connection, and the piston cylinder intercommunication has the tuyere towards the pivot outer wall. Magnet can drive the piston and move in the piston cylinder when the pivot internal motion, extrudes the mouth of blowing with the gas in the piston cylinder, blows off the winding behind the air knife lacerated from the mouth of blowing, avoids the winding to remain in the pivot to because pivot and building waste material frictional heating when smashing building waste material, the wind that the mouth of blowing blew off can also cool down the pivot.

Further, the cutter is located the top of antiwind subassembly, and the mouth of blowing is located the top of cutter. Adopt this structure can from the top down cut the entanglement, then blow from the top down, it is better to the entanglement blowoff effect after cutting.

Further, the longitudinal section of the protection sheet in each group of anti-winding assemblies is stepped, the protection sheet comprises a falling part and a protruding part, the falling part is located above the protruding part, and the falling part of the protection sheet in each group of anti-winding assemblies is in lap joint with the protruding part of the adjacent protection sheet. By adopting the structure, the problem that the winding rotating shaft is still wound when the winding object is clamped in the gap between the adjacent protection plates can be avoided.

Furthermore, the screening glass all is the arc of laminating mutually with the pivot outer wall. Screening glass laminates with the pivot outer wall mutually, avoids having the gap between screening glass and the pivot outer wall to make during the waste material dregs in the crushing barrel get into this gap.

Further, the group number of the anti-winding assemblies is one group. The number of the groups of the anti-winding assemblies is the minimum, and the wound can be spread only by one group of anti-winding assemblies.
