Description

Technical Field

[0001] This utility model relates to the field of building aggregate crushing technology, and in particular to a low-carbon and environmentally friendly building aggregate crushing device. Background Technology

[0002] In the construction industry, aggregate crushing equipment is crucial for breaking large stones into smaller particles, and is widely used in concrete, road construction, and other fields. Traditional aggregate crushing equipment typically consists of a crushing mechanism, a feeding mechanism, and a discharging mechanism. Its working principle involves a motor-driven crushing roller to compress and shear the stones, thereby achieving crushing. However, existing aggregate crushing equipment suffers from the following problems during operation:

[0003] Severe dust pollution: The dust generated during the crushing process not only affects the working environment but may also harm the health of operators. Existing dust control measures are mostly external spraying or dust collection devices, which have limited effectiveness and high energy consumption.

[0004] Poor heat dissipation: The crushing roller generates a lot of heat during high-speed rotation. If it cannot be dissipated in time, it may cause the equipment to overheat and affect its service life.

[0005] Complex structure and high maintenance costs: Existing equipment usually requires an additional power source to drive the dust removal and heat dissipation devices, resulting in a complex equipment structure and increased maintenance costs. Utility Model Content

[0033] Reference Figures 1-4 This invention provides a low-carbon and environmentally friendly building aggregate crushing device, including a crushing mechanism 100, a dust removal mechanism 200 and an auxiliary mechanism 300. The aim is to provide a device that can effectively crush building aggregates, efficiently remove dust, automatically dissipate heat and has a simple structure.

[0034] The crushing mechanism 100 includes a crushing roller 101, a motor 102, and a crusher housing 103. The crushing roller 101 is rotatably mounted inside the crusher housing 103, and its end is mechanically connected to the output shaft of the motor 102 via a large synchronous pulley 107 and a large synchronous belt 108 to achieve stable power transmission. Specifically, two sets of crushing rollers 101 are arranged. The end of one set of crushing rollers 101 is directly connected to the large synchronous pulley 107, while each set of crushing rollers 101 is also equipped with a set of large gears 109 at its end. The two sets of large gears 109 mesh with each other for transmission. The connection ensures that the two sets of crushing rollers 101 can rotate synchronously and in opposite directions, improving crushing efficiency; a feed box 104 is arranged at the top of the crusher box 103, and a feed hopper 105 is provided at the top of the feed box 104 to facilitate the input of building aggregates; a guide plate 110 is arranged in the feed box 104 below the feed hopper 105, and the bottom outlet of the guide plate 110 is located above the gap between the two sets of crushing rollers 101 to ensure that the aggregates can fall accurately into the crushing area; a discharge channel 106 is arranged at the bottom of the crusher box 103 for discharging the crushed aggregates.

[0035] The dust removal mechanism 200 includes a rotary nozzle 201, a connecting spiral tube 202, a water supply pipe 203, and a water pump 204. The rotary nozzle 201 is arranged in a ring array at the bottom of a hollow rotating disk 205, which is located at the top center of the feed box 104 and is fixedly connected to the connecting spiral tube 202. The top of the connecting spiral tube 202 is rotatably and sealed with the water supply pipe 203, which is connected to a water source through the water pump 204 to achieve a stable water supply. When the water pump 204 is started, water enters the connecting spiral tube 202 through the water supply pipe 203 and is finally sprayed out from the rotary nozzle 201, spraying the dust generated during the crushing process in all directions, significantly reducing dust pollution and improving the working environment.

[0036] The auxiliary mechanism 300 cleverly utilizes the rotational power of the crushing roller 101 to drive the dust removal mechanism 200. Specifically, the first pinion 301 is fixedly connected to the connecting tube 202, and a second pinion 302 is meshed and driven on one side of the first pinion 301. The second pinion 302 is fixedly connected to the synchronous shaft 303. The synchronous shaft 303 is rotatably mounted on the top of the feed box 104 and is mechanically connected to the connecting shaft 304 through a small synchronous pulley 305 and a small synchronous belt 306. The bottom of the connecting shaft 304 is connected to the connecting shaft 304 through a worm gear 3. 08 and worm gear 307 are fixedly connected to the end of one set of crushing rollers 101; therefore, when the crushing roller 101 rotates, its power is transmitted sequentially through worm gear 307, worm wheel 308, connecting shaft 304, small synchronous belt 306, synchronous shaft 303, second pinion 302 and first pinion 301 to the connecting rotary tube 202, which in turn drives the rotating nozzle 201 to rotate and spray; this design not only realizes the dust removal function, but also cools the crushing roller 101 through spray water, effectively reducing the equipment temperature and extending the service life of the equipment.

[0037] In this embodiment: First, the motor 102 is started; the motor 102 drives the crushing roller 101 to start rotating through the mechanical transmission of the large synchronous pulley 107 and the large synchronous belt 108; since each end of the two sets of crushing rollers 101 is provided with a set of large gears 109, and the two sets of large gears 109 mesh with each other, the two sets of crushing rollers 101 can achieve synchronous reverse rotation. This rotation mode can effectively squeeze and shear the input building aggregate.

[0038] At the same time, the building aggregate to be crushed is fed into the feed hopper 105. The guide plate 110 below the feed hopper 105 will guide the stone to the gap between the two sets of crushing rollers 101, so that it is subjected to the squeezing and shearing action of the crushing rollers 101, thereby realizing the crushing of the building aggregate.

[0039] During the crushing process, in order to reduce dust pollution and cool the equipment, the water pump 204 needs to be turned on. The water pump 204 supplies water to the connecting spiral pipe 202 through the water supply pipe 203. After passing through the connecting spiral pipe 202, the water is sprayed out from the rotating nozzle 201. During this process, the rotation of the crushing roller 101 drives the connecting shaft 304 to rotate through the transmission of the worm gear 307 and the worm wheel 308. The rotation of the connecting shaft 304 then drives the synchronous shaft 303 to rotate through the transmission of the small synchronous pulley 305 and the small synchronous belt 306. The second pinion 302 on the synchronous shaft 303 meshes with the first pinion 301. The first pinion 301 is fixedly connected to the connecting spiral pipe 202, so that the hollow rotating disk 205 rotates with the rotation of the connecting spiral pipe 202, thereby driving the rotating nozzle 201 to rotate automatically and achieve an all-round spraying effect.

[0040] In summary, this utility model achieves stone crushing by driving the crushing roller 101 to rotate via the motor 102; it achieves dust removal and cooling effects by supplying water via the water pump 204 and spraying water via the rotating nozzle 201; and the rotational power of the rotating nozzle 201 comes from the rotation of the crushing roller 101, eliminating the need for an additional power source. This design not only simplifies the equipment structure and reduces maintenance costs, but also improves the overall performance and environmental friendliness of the equipment.

[0041] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
