Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a construction waste crushing device. Background Technology

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during the production activities of the construction industry, such as demolition, construction, decoration, and repair.

[0003] Construction waste needs to be crushed during its recycling process. Because construction waste contains ferromagnetic components, the existing process first crushes the waste and then uses a ferromagnetic adsorption structure for adsorption. However, once the ferromagnetic adsorption structure is full, the machine needs to be stopped to clean it before crushing can continue. This results in frequent shutdowns, affecting the efficiency of waste crushing. To solve this technical problem, a construction waste crushing device is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 The present invention provides a structural diagram of a construction waste crushing device according to Embodiment 1. The construction waste crushing device includes: a housing 1, with a feed inlet 2 at the top; a crushing component installed inside the housing 1, positioned directly below the feed inlet 2; a dust removal mechanism positioned above the crushing component; a power disc 14 with a rotating shaft inside the housing 1, positioned below the crushing component; discharge ports 13 symmetrically arranged on the side wall of the housing 1, located above the power disc 14, the power disc 14 rotating to discharge crushed waste from the discharge ports 13; a rotating mounting ring 10 fitted onto the outer side of the housing 1, the mounting ring 10 having a plurality of electromagnetic adsorption components 11 arranged in a circular array inside, the electromagnetic adsorption components 11 having gaps between them and the outer wall of the housing 1 for discharging crushed waste; and a ferromagnetic discharge port 16 positioned between two discharge ports 13. The ferromagnetic discharge port 16 can be fixedly installed at the bottom of the housing 1 by bolts. The electromagnetic adsorption component 11 is existing technology and will not be described in detail here. The electromagnetic adsorption component 11 includes an electromagnet.

[0027] This invention reduces dust generation during the crushing process by setting up a dust removal structure. The rotating power disc 14 rotates the waste after crushing by the crushing components and discharges it through the discharge port 13. The waste impacts the electromagnetic adsorption component 11 adjacent to the discharge port 13, and the electromagnetic adsorption component 11 adsorbs the ferromagnetic parts in the waste. The construction waste falls and is discharged automatically under the action of gravity. When the ferromagnetic parts on the electromagnetic adsorption component 11 adsorbing the magnets are full, the mounting ring 10 rotates and transfers the next electromagnetic adsorption component 11 to the position adjacent to the discharge port 13. The electromagnetic adsorption component 11 full of ferromagnetic parts is transferred to the ferromagnetic discharge port 16 directly below it and discharged by power-off. In this way, continuous waste crushing is achieved, avoiding the problem of needing to stop the machine to remove ferromagnetic parts in the prior art and improving work efficiency.

[0028] In a preferred embodiment of this utility model, the dust removal mechanism includes a water supply ring 3 disposed inside the housing 1. The water supply ring 3 is externally connected to a water supply system, which provides a water source for the water supply ring 3. The water supply ring 3 has a ring-shaped structure, and a plurality of nozzles 4 are arranged in a circular array at the bottom of the water supply ring 3. The input end of each nozzle 4 is connected to the interior of the water supply ring 3, and the water supply ring 3 provides a water source for the nozzles 4 so that the nozzles 4 can spray water to remove dust from the garbage. The water supply system is prior art and will not be described in detail here.

[0029] In a preferred embodiment of the present invention, the crushing assembly includes two parallel crushing rollers 5, which are rotatably mounted inside the housing 1. In order to drive the two crushing rollers 5 to rotate, a crushing power assembly is also installed on the housing 1. The crushing power assembly is connected to the two crushing rollers 5 in a transmission connection to provide power for the rotation of the two crushing rollers 5.

[0030] In a preferred embodiment of this utility model, a toothed ring 9 is fixedly sleeved on the outer side of the mounting ring 10. The toothed ring 9 meshes with a gear 8, which is located at the output end of the drive motor 7. When the drive motor 7 is energized, it drives the gear 8 to rotate, thereby rotating the toothed ring 9 and the electromagnetic adsorption component 11. The energized drive motor 7 provides power for the rotation of the gear 8, which in turn drives the toothed ring 9 and the mounting ring 10 to rotate, thus switching the position of the electromagnetic adsorption component 11. The drive motor 7 is fixedly mounted on the housing 1.

[0031] In a preferred embodiment of the present invention, a plurality of position switches 12 are installed inside the mounting ring 10. The number of position switches 12 is equal to that of the electromagnetic adsorption components 11. Each position switch 12 is electrically connected to an adjacent electromagnetic adsorption component 11. The position switches 12 are used to control the energization or de-energization of the electromagnetic adsorption components 11.

[0032] In order to enable the position switch 12 to be pressed and de-energized when it reaches the set position, two abutment blocks 18 are symmetrically installed on the mounting ring 17. The mounting ring 17 is fixedly sleeved on the housing 1, and the mounting ring 10 is rotatably sleeved on the outside of the mounting ring 17. The abutment blocks 18 are set on the trajectory of the position switch 12. The distance between the side of the abutment block 18 away from the mounting ring 17 and the outside of the mounting ring 17 gradually increases. In this way, when the position switch 12 passes the abutment block 18, the abutment block 18 gradually squeezes the position switch 12, so that the position switch 12 de-energizes the connected electromagnetic adsorption component 11, so that the electromagnetic adsorption component 11 causes the electromagnetic component to fall into the electromagnetic adsorption component 11 under the action of gravity.

[0033] like Figure 1 and 4 As shown, in another preferred embodiment of the present invention, the drive motor 7 can be a reciprocating motor. When the electromagnetic adsorption component 11 removes the ferromagnetic component, the drive motor 7 rotates in the opposite direction so that the electromagnetic adsorption component 11 returns to the initial position.

[0034] To drive the power disc 14 to rotate, a rotary motor 15 is fixedly installed inside the housing 1. The power disc 14 is connected to the rotary motor 15, and the rotary motor 15 provides power for the rotation of the power disc 14. A protective metal cover is fitted around the rotary motor 15 to prevent it from being hit by construction debris during use.

[0035] The working principle of this utility model is as follows:

[0036] The waste to be processed falls onto two crushing rollers 5 through the feed inlet 2. The crushing rollers 5 rotate to crush the waste, while the nozzles 4 spray water onto the waste to reduce dust. After crushing, the waste falls onto the power disc 14. The power disc 14 rotates and the waste is discharged through the discharge port 13 under the action of centrifugal force. Then it hits the electromagnetic adsorption component 11. The electromagnetic adsorption component 11 adsorbs the ferromagnetic parts, while the waste falls automatically under the action of gravity. After the electromagnetic adsorption component 11 adsorbs for a period of time, the drive motor 7 rotates through the gear 8 and the mounting ring 10, which causes the fully adsorbed electromagnetic adsorption component 11 to be transferred to the top of the ferromagnetic discharge port 16. The position switch 12 touches the contact block 18, and the electromagnetic adsorption component 11 located directly above the ferromagnetic discharge port 16 is de-energized. The ferromagnetic parts on the electromagnetic adsorption component 11 fall automatically under the action of gravity and are discharged through the ferromagnetic discharge port 16.
