Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of sand and gravel aggregate production technology, specifically a crushing equipment for sand and gravel aggregate processing. Background Technology
[0002] In the sand and gravel aggregate processing industry, crushing equipment is a crucial component. Traditional crushing equipment for sand and gravel aggregate processing has revealed several problems that urgently need to be addressed during actual operation. First, during crushing operations, a large amount of dust is generated and dispersed into the surrounding environment along with the material being crushed. This dust not only poses a serious threat to the health of operators but also negatively impacts the surrounding air quality, failing to meet environmental protection requirements. Second, the crushed material often needs to be screened and separated to separate qualified sand and gravel aggregates from impurities such as silt. Existing equipment cannot effectively achieve this screening and separation, resulting in a significant amount of impurities mixed in with the finished sand and gravel aggregates, affecting product quality. Simultaneously, wastewater and silt generated during the crushing process easily accumulate at the bottom of the equipment. If not cleaned promptly, this can cause blockages, affecting the normal operation and service life of the equipment. Utility Model Content
[0003] To achieve the above objectives, this utility model employs the following technical solution:
[0004] A crushing device for processing sand and gravel aggregates includes a crusher body, a feed inlet at the top of the crusher body, a hinged baffle at the top of the inner wall of the crusher body below the feed inlet, a crushing chamber near the middle of the inner wall of the crusher body, crushing rollers symmetrically arranged inside the crushing chamber, a first spray pipe and a second spray pipe fixedly arranged on both sides of the crusher body, a screen fixedly arranged at the bottom of the crushing chamber, a discharge outlet near the bottom of the crushing chamber on the side of the crusher body, and a sewage pipe fixedly arranged at the bottom of the crusher body.
[0005] A torsion spring is provided at the hinge point between the baffle and the inner wall of the crusher. One end of the torsion spring abuts against the bottom of the baffle and the other end abuts against the inner wall of the crusher.
[0006] A first spray pipe is fixedly installed on the side of the crusher body near the top of the crushing chamber, and a second spray pipe is fixedly installed on the other side of the crusher body near the bottom of the crushing chamber. Spray heads are fixedly installed at the ends of the first spray pipe and the second spray pipe. The second spray pipe is inclined and points towards the bottom of the discharge port.
[0007] The other end of the screen abuts against the discharge port, the screen is inclined, and the bottom of the crusher body is inclined.
[0008] Compared with the existing technology, the beneficial effects of this utility model are:
[0009] This utility model has a simple structure and is easy to install and use. The baffle is used in conjunction with a torsion spring. When the material is poured in, the baffle flips to discharge the material and then automatically rebounds, effectively preventing dust from spreading outward from the feed inlet. At the same time, the first spray pipe at the top of the crushing chamber sprays dust during the material falling process, which greatly reduces dust flying and reduces dust pollution to the surrounding environment.
[0010] The inclined screen, which abuts against the discharge port, allows the crushed material to roll naturally to the discharge port under gravity, preventing it from mixing with impurities such as mud and sand. The wastewater and impurities filtered by the screen can slide smoothly to the bottom and be discharged through the drain pipe. In addition, the inclined second spray pipe at the bottom of the crushing chamber near the discharge port can wash away the mud and sand accumulated at the bottom of the equipment, preventing mud and sand from accumulating and causing blockages, extending the service life of the equipment, ensuring the continuous and stable operation of the equipment, and improving production efficiency.

[0015] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0016] Referring to the accompanying drawings, a crushing device for processing sand and gravel aggregates includes a crusher body 1. A feed inlet 2 is provided at the top of the crusher body 1. A baffle 3 is hinged to the top of the inner wall of the crusher body 1 below the feed inlet 2, and the baffle 3 abuts against the top of the inner wall of the crusher body 1. A crushing chamber 4 is provided near the center of the inner wall of the crusher body 1. Crushing rollers 5 are symmetrically arranged inside the crushing chamber 4 and are rotatably connected to the inner wall of the crusher body 1. A drive motor and transmission assembly for driving the crushing rollers 5 are provided on the outer wall of the crusher body 1. The crushing rollers 5 are existing technology and will not be described in detail in this application. A first spray pipe 6 and a second spray pipe 7 are fixedly arranged on both sides of the crusher body 1. A screen 8 is fixedly arranged at the bottom of the crushing chamber 4, and the screen 8 has an array of through holes. A discharge port 9 is provided on the side of the crusher body 1 near the bottom of the crushing chamber 4. A sewage pipe 10 is fixedly arranged at the bottom of the crusher body 1.
[0017] A torsion spring 11 is provided at the hinge point between the baffle 3 and the inner wall of the crusher body 1. One end of the torsion spring 11 abuts against the bottom of the baffle 3 and the other end abuts against the inner wall of the crusher body 1. This structural design prevents dust from spreading out of the machine body while not affecting the material feeding.
[0018] A first spray pipe 6 is fixedly installed on the side of the crusher body 1 near the top of the crushing chamber 4 to reduce dust. A second spray pipe 7 is fixedly installed on the other side of the crusher body 1 near the bottom of the crushing chamber 4. Spray heads are fixedly installed at the ends of both the first spray pipe 6 and the second spray pipe 7 and both are connected to a water pump. The second spray pipe 7 is inclined and points to the bottom of the discharge port 9. This structural design is used to wash away the mud and sand accumulated at the bottom of the crusher body 1.
[0019] The other end of the screen 8 abuts against the discharge port 9. The screen 8 is inclined and the bottom of the crusher body 1 is inclined. This structural design allows the crushed material to be discharged while the mud and sand are separated and discharged.
[0020] When the device is in use, the stones to be crushed are poured into the feed inlet 2. The baffle 3 is flipped by the weight of the stones, and then the stones fall into the crushing chamber 4. During the fall, the liquid sprayed from the first spray pipe 6 reduces dust on the stones. After being crushed by the crushing roller 5, the stones fall onto the screen 8 and then roll down to the discharge port 9 for discharge. The wastewater and impurities generated during crushing are filtered by the screen 8 and fall to the bottom of the crusher body 1 and are discharged through the sewage pipe 10.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
