Abstract
Description
Technical Field
[0001] This utility model relates to the field of aggregate crushing equipment, specifically a crushing device for fine sand aggregate from construction waste. Background Technology
[0002] Construction waste, without any treatment, is transported to the suburbs or urban peripheries for simple landfill or open-air storage. This not only wastes land and resources but also pollutes the environment. Therefore, it is necessary to utilize construction waste recycling to produce recycled aggregates. Currently, existing construction waste fine sand aggregate crushing and molding equipment cannot complete the screening of aggregates during use.
[0003] According to the patent document CN217017428U, a crushing and forming device for fine sand aggregate of construction waste and its cleaning and separation mechanism are disclosed. The device includes a main body, with a cleaning mechanism and a separation mechanism inside. The cleaning mechanism includes a first filter screen, a suction pipe, a suction fan, a discharge pipe, a collection box, a second filter screen, a ejector pin, and a telescopic cylinder. A suction pipe is located on the right side of the first filter screen, and a suction fan is fixedly connected to the right side of the suction pipe. A discharge pipe is installed on the right side of the suction fan, and a collection box is fixedly connected to the bottom of the discharge pipe. In this technical solution, when the filter screen becomes clogged, the cleaning mechanism cleans the clogged area, and the separation mechanism separates the iron filings and impurities from the fine sand aggregate, thus completing the cleaning of the filter screen and the separation of impurities from the fine sand aggregate. However, while this solution achieves the cleaning of the filter screen, the agitation and buffering of the crushed material during use prevents the full adsorption of magnets from the crushed material, resulting in inconvenience during use. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a crushing device for fine sand aggregate of construction waste, thereby solving the problems mentioned in the background technology. This utility model has a novel structure. After being crushed by the crushing cone seat, the material falls onto the fixed column. The fixed column obstructs and moves the material, which facilitates the diffusion of the material around the edges. The adsorption force generated by the electromagnet ring effectively and fully adsorbs the metal in the material.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a construction waste fine sand aggregate crushing device, comprising a box body, a drive motor fixed at the bottom of the box body, an output shaft fixedly mounted on the drive motor, a crushing cone seat fixed at one end of the output shaft, a limiting seat mounted on the side of the crushing cone seat, the limiting seat fixed to the top of the box body, a feed cylinder fixedly mounted on the top of the box body and the limiting seat, an electromagnet ring fixedly mounted inside the limiting seat, and a fixing column fixedly mounted on the inner wall of the electromagnet ring.
[0006] Furthermore, the bottom of the crushing cone seat has an annular groove, and a sealing cylinder is movably installed inside the annular groove. A support seat is welded to one end of the sealing cylinder.
[0007] Furthermore, a support column is welded onto the support base, and an inclined block is fixed to the bottom of the crushing cone base, with the support column and the inclined block in movable contact.
[0008] Furthermore, a ring seat is fixed to the side of the support base, and an arc-shaped plate is fixed on the ring seat. Both the arc-shaped plate and the ring seat are fixed to the inner wall of the box.
[0009] Furthermore, a screening plate is fixedly installed on the support base, and an opening is opened at one end of the screening plate. The opening is located on the box body, and a discharge hopper is fixedly installed between the box body and the opening.
[0010] Furthermore, a discharge port is provided at the bottom of the box, which cooperates with the screening plate. A support frame is fixed at the bottom of the box, and protrusions are welded to the sides of the crushing cone seat.
[0011] Furthermore, a movable cylinder is welded to the bottom of the support base, and a support cylinder is movably installed inside the movable cylinder, with the support cylinder fixed to the bottom of the box body.
[0012] Furthermore, a sliding groove is formed on the outer wall of the support cylinder, and a slider is movably installed inside the sliding groove. The slider is fixed on the inner wall of the movable cylinder, and a support mechanism is fixed between the slider and the sliding groove.
[0013] The beneficial effects of this utility model are:
[0014] This construction waste fine sand aggregate crushing device involves crushing the material by means of a crushing cone seat, which then drops the crushed material onto a fixed column. The fixed column obstructs and moves the material, which facilitates the diffusion of the material around the edges. The adsorption force generated by the electromagnet ring effectively adsorbs the metal in the material.
[0015] This construction waste fine sand aggregate crushing device, when the crushing cone seat rotates to crush the aggregate, pushes the support column through the inclined block to make the support seat and the screening plate swing up and down repeatedly. The swinging is beneficial to the screening and filtering of materials. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a crushing device for fine sand aggregate of construction waste, including a box body 1. A drive motor 18 is fixed at the bottom of the box body 1. An output shaft 19 is fixedly installed on the drive motor 18. A crushing cone seat 5 is fixed at one end of the output shaft 19. A limiting seat 25 is installed on the side of the crushing cone seat 5. The limiting seat 25 is fixed to the top of the box body 1. A feed cylinder 2 is fixedly installed on the top of the box body 1 and the limiting seat 25. An electromagnet ring 7 is fixedly installed inside the limiting seat 25. A fixing column 8 is fixedly installed on the inner wall of the electromagnet ring 7. An annular groove 9 is opened at the bottom of the crushing cone seat 5. A sealing cylinder 10 is movably installed inside the annular groove 9. A support seat 13 is welded to one end of the sealing cylinder 10. When the electromagnet ring 7 is energized, it generates a suction force to adsorb metal. The metal is adsorbed on the limiting seat 25, avoiding the impact caused by the material being pushed out later.
[0023] In this embodiment, a support column 11 is welded onto the support base 13, and an inclined block 12 is fixed to the bottom of the crushing cone seat 5. The support column 11 and the inclined block 12 are in movable contact. A ring seat 23 is fixed to the side of the support base 13, and an arc plate 24 is fixed on the ring seat 23. Both the arc plate 24 and the ring seat 23 are fixed to the inner wall of the box body 1. A screening plate 14 is fixedly installed on the support base 13. One end of the screening plate 14 has an opening, which is located on the box body 1. A discharge hopper 3 is fixedly installed between the box body 1 and the opening. The ring seat 23 and the arc plate 24 cooperate to screen the falling material only through the screening plate 14, thereby avoiding the impact caused by the accumulation of material inside the box body 1.
[0024] In this embodiment, a discharge port 17 is provided at the bottom of the box body 1. The discharge port 17 cooperates with the screening plate 14. A support frame 4 is fixed at the bottom of the box body 1. A protrusion 6 is welded to the side of the crushing cone seat 5. A movable cylinder 15 is welded to the bottom of the support seat 13. A support cylinder 16 is movably installed inside the movable cylinder 15. The support cylinder 16 is fixed to the bottom of the box body 1. A sliding groove 20 is provided on the outer wall of the support cylinder 16. A slider 21 is movably installed inside the sliding groove 20. The slider 21 is fixed on the inner wall of the movable cylinder 15. A support mechanism 22 is fixed between the slider 21 and the sliding groove 20. The support mechanism 22 is a support spring. The support spring pushes the support seat 13 to return to its upward position. By the up and down shaking of the support seat 13, the screening plate 14 shakes up and down synchronously to facilitate the downward sliding of materials in the later stage and avoid the blockage caused by the accumulation of materials on the screening plate 14.
[0025] In use, construction waste is fed into the feed cylinder 2. The drive motor 18 is started to rotate the crushing cone seat 5. As the crushing cone seat 5 rotates, it crushes the material moving in the limiting seat 25. The crushing cone seat 5 completes the crushing process by striking the material with the protrusion 6 and squeezing it with the limiting seat 25. The crushed material falls onto the fixed column 8, which blocks and pushes the material, facilitating its diffusion. The adsorption force generated by the electromagnet ring 7 effectively adsorbs the metal in the material. After the material falls onto the screening plate 14, it is crushed. The rotation of the conical seat 5 causes the inclined block 12 to cooperate with the support column 11 to push the support seat 13 and the screening plate 14 downward. After the inclined block 12 separates from the support column 11, the support seat 13 is pushed upward by the thrust of the support mechanism 22. The up and down shaking of the screening plate 14 facilitates the rapid screening of materials. The materials falling through the screening plate 14 are discharged downward through the discharge port 17. Larger particles are discharged from the discharge hopper 3 under the shaking of the screening plate 14. After the materials are completely discharged, the electromagnet ring 7 is de-energized. After the power is de-energized, the metal materials fall onto the screening plate 14 and are discharged in a concentrated manner, thereby realizing the screening and use of materials.
