Description

Construction waste recovery device and recovery method thereof

Technical Field

The invention relates to the technical field of jaw crushers, in particular to a construction waste recycling device and a recycling method thereof.

Background

The jaw crusher simulates two jaw motions of animals to realize crushing of materials, and is widely applied to crushing of various stone materials in industries such as mine smelting, building materials, highways, railways and the like, the conventional jaw crusher mainly comprises a driving device, a movable jaw part, a static jaw part and an adjusting and protecting structure, and the main working principle of the jaw crusher is that the movable jaw part is driven by the driving device to perform reciprocating motion, so that the movable jaw is continuously close to and far away from the static jaw, and then the stone materials clamped between the movable jaw and the static jaw are subjected to friction kneading extrusion to realize crushing, when hard materials are encountered, the whole equipment can be protected by fracture of an elbow plate in the adjusting and protecting structure, and the whole equipment is prevented from being damaged due to overload, but the conventional jaw crusher has some problems in the using process, and the jaw crusher is specific as follows:

the extrusion breakage of material is realized through the motion of moving the jaw to current device, but because move jaw and quiet jaw and be the triangle-shaped setting, and quiet jaw is vertical setting, the material just carries out the interlock of material through the motion of moving the jaw between two jaws purely like this, and this kind of mode is when bumping into the stone material that the angle that some shapes just in time constituted with two jaws, can appear the stone material card all the time between two jaws, can not be fine carry out the upset of angle to the stone material, and then the feeding of the material of being not convenient for, this kind of extrusion breakage process to the material simultaneously is that the stone material just can get into between two jaws and carry out the breakage, and the interlock feeding of the device to the material is not convenient for more on the one hand to the mode of sliding friction, also greatly increased the friction loss to two jaws when the material is broken simultaneously, and then increase the change frequency of jaw, and the production use cost is improved.

The existing device can be provided with an adjusting protection structure, namely a toggle plate structure, at the bottom of a movable jaw plate, the structure can limit the movement of the jaw plate and can also break when the device breaks materials with overhigh hardness to protect the jaw plate, but the toggle plate and a toggle plate seat in the existing toggle plate structure do reciprocating friction movement along with the movement of the movable jaw plate, and the movement is also sliding friction, so that after the device runs for a long time, serious friction loss is generated between the toggle plate and the toggle plate seat to thin the end part of the toggle plate, the hardness of stone materials which can be broken by the device after the device runs for a certain time can be reduced, namely the hardness of the stone materials exceeds the end part of the toggle plate after being worn and thinned, the toggle plate is broken by the device, the device needs to be stopped to replace a new toggle plate, the replacement of the toggle plate can increase the use cost of the whole device, and the movable jaw plate can collide with a device body after the toggle plate is broken, and certain device damage can also occur.

it should be noted that, the roller 125 capable of moving up and down is arranged inside the docking frame 124, and in combination with the arrangement of the T-shaped structure of the first toggle plate 126 at the inner end of the docking frame 124, the requirement of the first toggle plate 126 for angle change during movement of the first toggle plate 126 through the pressing roller 125 can be met when the movable jaw 4 makes continuous telescopic movement relative to the docking frame 124, so as to avoid the limitation of flexibility by rigidity during the whole movement of the first toggle plate 126 and the second toggle plate 127, and at the same time, due to the arrangement of the angle between the first toggle plate 126 and the second toggle plate 127, when the device is crushed to a material with too high hardness, a strong force is transmitted to the fracture protection plate 128, so that the fracture protection plate 128 is fractured, and at the same time, the first toggle plate 126 and the second toggle plate 127 are folded and rotated in an upward convex manner, and the movable jaw 4, after being broken, may be in impact contact with the stacked state of the first toggle plate 126 and the second toggle plate 127, thus, one part of the moment of inertia of the movable jaw block 4 when the movable jaw block is in a fault is absorbed by the clockwork spring at the connecting end of the first toggle plate 126 and the second toggle plate 127, and the other part of the moment of inertia is impacted with the first toggle plate 126 and the second toggle plate 127, so that the damage of the machine body caused by the impact of the movable jaw block 4 and the machine body is avoided, the integrity of the device is further protected, the angle between the first toggle plate 126 and the second toggle plate 127 is not fixed, the angle can be adjusted according to the hardness of the material to be crushed according to actual needs, then the fracture protection plate 128 with different bending degrees is installed, the larger the bending degree is, the fracture protection plate 128 is easy to break, the lower the hardness threshold value of the existing crushable material of the device is indicated, the device can flexibly adjust the degree of the crushable material, and the practicability of the device is improved.

Please refer to fig. 3, which shows a construction waste recycling device, comprising a linkage structure 14, wherein the linkage structure 14 is movably connected by a support shaft connected between the front and back sides of the inner lower side of the machine body housing 1, and two ends of the linkage structure 14 are respectively movably connected with the movable jaw block 4 and the bottom end of the second movable jaw 10, and the rotation center of the linkage structure 14 is set to be biased to one side of the second movable jaw 10;

it should be noted that, the center of rotation of the linkage structure 14 is set to be eccentric to the second movable jaw 10, so that the force generated by the movable jaw 4 when the driving structure drives to move can be at the effort-saving end of a lever structure, and thus the force of the same magnitude can more easily make the second movable jaw 10 at the effort-saving end move, thereby reducing the overall load of the driving device as a whole, and the moving direction of the movable jaw 4 and the moving direction of the second movable jaw 10 are always opposite under the linkage action of the linkage structure 14, so that the moving inertia generated by the movable jaw 4 when moving downwards and the moving inertia generated by the second movable jaw 10 when moving upwards cancel a part of each other, that is, a downward pressure is applied to the inside of the machine body housing 1 while an upward lifting force is applied, so that the force received by the whole machine body housing 1 is greatly reduced, and this part of force is the reason for causing the whole device to vibrate, thereby greatly reducing the vibration of the device during operation and improving the stability of the whole operation of the device.
