Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a crushing device for building construction. Background Technology

[0002] In construction, some construction waste, such as cement, can be crushed using a crusher for reuse. Since construction waste typically contains a large amount of metal scraps such as rebar fragments, wire, bolts, and screws, separating and recycling these metal scraps separately helps improve recycling efficiency and yields good economic benefits.

[0003] Authorization document CN221638238U discloses a crusher for construction, including a processing box and a crushing box. The processing box contains a separation mechanism, which includes two rotating shafts. A first fixed wheel is fixedly sleeved on the outer surface of the left rotating shaft, and a second fixed wheel is fixedly sleeved on the outer surface of the right rotating shaft. A connecting magnetic ring is fixedly sleeved on the outer surface of the second fixed wheel. A first magnetic plate and a second magnetic plate, matching the upper and lower surfaces of the connecting magnetic ring, are fixedly connected between the inner walls of the processing box. This device uses the first magnetic plate, the second magnetic plate, and the connecting magnetic ring to generate magnetic attraction, causing metal materials transported on the conveyor belt to remain adhered to the belt during transport until they reach the boundary of the second magnetic plate. At this point, the magnetic force decreases and eventually disappears, causing the metal materials to fall off and be recovered.

[0004] However, this device still suffers from the following problems: the mass and shape of the metal materials transported on the conveyor belt vary greatly, and there is also a rotating conveyor belt driven by power between the metal materials and the magnetic structure. Those skilled in the art can foresee that when the magnetic force is too strong, the metal materials will overcome the force of the conveyor belt and remain stationary, not moving with it; when the magnetic force is too weak, the metal materials will struggle to overcome gravity and fall into the non-metallic material recycling tank along with the non-metallic materials; even with a moderate magnetic force, only a portion of the material is recovered in the recycling tank, as materials that are too large or too small are either recycled by the non-metallic materials or remain on the conveyor belt. Therefore, this device suffers from low metal material recovery efficiency and poor practicality. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a crushing device for construction, which achieves the purpose of capturing and collecting metal materials by setting waste outlet and metal outlet at the downstream end of the conveyor belt, and equipping the metal outlet with a magnetic plate structure. It has the advantages of high recycling efficiency and strong practicality.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A crushing device for construction includes a processing box, a conveyor belt structure disposed within the processing box, and a recycling structure disposed on the side wall of the processing box and located downstream of the conveyor belt structure. The conveyor belt structure includes at least two conveyor rollers rotatably disposed within the processing box and a conveyor belt. The recycling structure includes a waste outlet disposed on the side wall of the processing box parallel to the conveyor rollers, a waste receiving box disposed outside the processing box and connected to the waste outlet, a metal outlet disposed on the side wall of the processing box perpendicular to the conveyor rollers, a metal receiving box disposed outside the processing box and connected to the metal outlet, and a magnetic plate structure disposed at the metal receiving box.

[0008] As a further preferred embodiment of the present invention, the metal receiving box includes a box body with an open top and the opening being connected to the metal output port; the magnetic plate structure includes a magnetic plate body slidably connected to the box body, and a driving member disposed on the box body and driving the magnetic plate body to move closer to / away from the metal output port.

[0009] As a further preferred embodiment of the present invention, the driving component includes a rotating motor disposed on the side wall of the housing body away from the metal output port, a threaded rod disposed on the output end of the rotating motor, an internal threaded hole disposed on the magnetic plate body and threadedly connected to the threaded rod, a limiting rod disposed on the side wall of the housing body and parallel to the threaded rod, and a limiting hole disposed on the magnetic plate body and used to pass through the limiting rod.

[0010] As a further preferred embodiment of the present invention, the magnetic plate structure further includes a cleaning component disposed within the housing body, parallel to the magnetic plate body, and located on the side end of the magnetic plate body near the metal output port.

[0011] As a further preferred embodiment of the present invention, the cleaning component includes a threaded ring screwed onto the side end of the threaded rod near the metal outlet, and a rotating rod disposed on the outer periphery of the threaded ring.

[0012] As a further preferred embodiment of the present invention, the cleaning component further includes brush bristles disposed on the surface of the rotating rod near the magnetic plate body.

[0013] As a further preferred embodiment of the present invention, the cleaning component further includes two limiting rings disposed on the threaded rod and located on both sides of the threaded ring.

[0014] As a further preferred embodiment of the present invention, the conveyor belt structure further includes a diversion structure disposed at the upper end of the conveyor belt near the recycling structure; the diversion structure includes a middle partition disposed at the center line of the conveyor belt and aligned with the conveying direction of the conveyor belt, and a guide plate disposed on the end of the middle partition near the waste outlet and inclined toward the metal outlet.

[0015] As a further preferred embodiment of the present invention, the diversion structure further includes a connecting rod disposed on the upper end of the partition plate and / or the guide plate, and a connecting member disposed on the upper end of the connecting rod and detachably connected to the top wall of the processing box.

[0016] As a further preferred embodiment of this utility model, there are two metal output ports, symmetrically distributed on two opposite side walls of the processing box; there are two guide plates, symmetrically arranged with the partition plate as the axis.

[0017] The beneficial effects of this utility model are as follows:

[0018] This device achieves the purpose of capturing and collecting metal materials by setting waste outlets and metal outlets at the downstream end of the conveyor belt, and equipping the metal outlets with magnetic plate structures. Furthermore, as long as the magnetic force of the magnetic plate structure is large enough to attract the metal material with the largest mass, the screening effect and screening efficiency of the metal material can be guaranteed. Compared with existing technologies, it has a larger magnetic force range required for the magnetic plate structure, which is beneficial for practical applications.

[0019] This device reduces the distance between the raw material and the magnetic plate structure by controlling the position of the raw material on the conveyor belt through a diversion structure, ensuring that the magnetic plate structure can fully act on the metal material, thereby improving the screening and collection effect of the metal material.

[0034] Example 1

[0035] This embodiment provides a crushing device for building construction, including a processing box 1, a conveyor belt structure 2 disposed within the processing box 1, and a recycling structure 3 disposed on the side wall of the processing box 1 and located downstream of the conveyor belt structure 2; wherein...

[0036] The conveyor belt structure 2 includes at least two conveyor rollers 21 rotatably disposed within the processing box 1 and a conveyor belt 22.

[0037] The recycling structure 3 includes a waste outlet 31 disposed on the side wall of the processing box 1 parallel to the conveyor roller 21, a waste receiving box 32 disposed outside the processing box 1 and connected to the waste outlet 31, a metal outlet 33 disposed on the side wall of the processing box 1 perpendicular to the conveyor roller 21, a metal receiving box 34 disposed outside the processing box 1 and connected to the metal outlet 33, and a magnetic plate structure 35 disposed at the metal receiving box 34.

[0038] It is understood that the processing box 1 is preferably a horizontal box body, with a feeding hopper provided at the upper end of one side, and the waste output port 31 and metal output port 33 respectively provided on the side wall away from the feeding hopper. The conveyor belt 22 is used to output the raw materials input from the feeding hopper to the outlet. More preferably, a motor and a crushing structure connected to the output end of the motor can be provided at the feeding hopper for further crushing of the raw materials. The crushing structure is prior art in the art, so it will not be described in detail.

[0039] It is worth noting that there are two metal output ports 33, symmetrically distributed on two opposite side walls of the processing box 1; there are also two metal receiving boxes 34 and two magnetic plate structures 35, corresponding to the metal output ports 33. The magnetic plate structure 35 refers to a plate with magnets installed to attract metal materials. Preferably, the size of the magnets is large enough to cover the size of the metal output ports, thereby ensuring sufficient attraction to attract the magnets.

[0040] As a further preferred embodiment, the conveyor belt structure 2 further includes a diversion structure 23 disposed at the upper end of the conveyor belt 22 near the recycling structure 3; the diversion structure 23 includes a partition plate 231 disposed at the centerline of the conveyor belt 22 and aligned with the conveying direction of the conveyor belt 22, a guide plate 232 disposed on the end of the partition plate 231 near the waste outlet 31 and inclined toward the metal outlet 33, a connecting rod 233 disposed on the upper end of the partition plate 231 and / or the guide plate 232, and a connector 234 disposed on the upper end of the connecting rod 233 and detachably connected to the inner top wall of the processing box 1. There are two guide plates 232, symmetrically arranged about the partition plate 231 as an axis.

[0041] In this embodiment, the main technical effect of the diversion structure 23 is to guide the transported raw materials from the middle of the conveyor belt 22 to both sides of the conveyor belt 22. By reducing the distance between the raw materials and the magnetic plate structure 35, the success rate of the magnetic plate structure 35 in attracting metal materials is improved. Raw materials that are not attracted by the magnet continue to move along the transport direction of the conveyor belt 22 after diversion, and are discharged from the waste outlet 31. It is worth noting that the distance between the partition plate 231 and the two guide plates 232 and the surface of the conveyor belt 22 should be as small as possible without generating frictional force that would damage the materials, so as to avoid the raw materials getting stuck in the gap between them. Brush bristles can also be provided on the lower surface of the partition plate 231 and the guide plates 232 near the conveyor belt 22, which can both block the flow and reduce frictional wear. The structure of the connecting rod 233 and the connector 234 is mainly for the convenience of disassembling and assembling the diversion structure 23. Existing technologies such as bolts can be used to achieve this, so it will not be described in detail.

[0042] The crushing device provided in this embodiment has the following basic working principle: the raw material is input from the upper end of one side of the processing box 1 and is conveyed in the box by the conveyor belt 22. When it is conveyed to the downstream, the diversion structure 23 diverts the raw material. Due to the inclined structure of the guide plate 232, the raw material in the middle moves to both ends and then approaches the metal output port 33. The magnetic plate structure 35 attracts the iron and other metal materials in the raw material. The lighter materials are directly attracted to the surface of the magnetic plate structure 35, while the heavier materials approach the magnetic plate structure 35 under the action of magnetic force and fall into the metal receiving box 34 for collection. The remaining raw material moves to the waste output port 31 after passing through the diversion structure 23 and is collected by the waste receiving box 32.

[0043] Example 2

[0044] This embodiment optimizes the recycling structure based on Embodiment 1, as follows:

[0045] The metal receiving box 34 includes a box body 341 with an open top and an opening that mates with the metal output port 33; the magnetic plate structure 35 includes a magnetic plate body 351 that is slidably connected to the box body 341, and a driving member 352 that is disposed on the box body 341 and drives the magnetic plate body 351 to move closer to / away from the metal output port 33.

[0046] The upper surface of the opening of the box body 341 is flush with the bottom surface of the metal output port 33, thereby ensuring that the metal material can enter the box body 341 without jamming. Furthermore, considering that there is a gap between the conveyor belt 22 and the metal output port 33, an extension plate can be provided at the metal output port 33 (i.e., on the side wall of the processing box 1) to facilitate the discharge of materials from the metal output port 33.

[0047] As a further preferred embodiment, the driving component 352 includes a rotary motor 352a disposed on the side wall of the housing body 341 away from the metal output port 33, a threaded rod 352b disposed on the output end of the rotary motor 352a, an internal threaded hole 352c disposed on the magnetic plate body 351 and threadedly connected to the threaded rod 352b, a limiting rod 352d disposed on the side wall of the housing body 341 and parallel to the threaded rod 352b, and a limiting hole 352e disposed on the magnetic plate body 351 for passing through the limiting rod 352d. The rotary motor 352a drives the threaded rod 352d to rotate, causing the magnetic plate body 351 to move closer to / away from the metal output port 33 under the guidance of the limiting rod 352d. This adjusts the distance between the magnetic plate body 351 and the metal output port 33 according to the characteristics, especially the mass, of the metal material in the raw material, thereby controlling the magnetic force of the magnetic plate body 351 on the metal material on the conveyor belt 22.

[0048] As a further preferred embodiment, the magnetic plate structure 35 further includes a cleaning member 353 disposed within the housing body 341, parallel to the magnetic plate body 351, and located on the side end of the magnetic plate body 351 near the metal output port 33. The cleaning member 353 includes a threaded ring 353a screwed onto the side end of the threaded rod 352b near the metal output port 33, a rotating rod 353b disposed on the outer periphery of the threaded ring 353a, bristles 353c disposed on the surface of the rotating rod 353b near the magnetic plate body 351, and two limiting rings 353d disposed on the threaded rod 352b and located on both sides of the threaded ring 353a. Specifically, the rotation of the threaded rod 352b drives the threaded ring 353a to rotate, which in turn causes the rotating rod 353b to rotate. This allows the rotating rod 353b to sweep away the metal material adsorbed on the surface of the magnetic plate body 351 when the magnetic plate body 351 moves close to the rotating rod 353b, so that the metal material can fall into the box body 341 and avoid the adsorbed metal material from affecting the magnetic force of the magnetic plate body 351.

[0049] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
