Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a high-efficiency stone crushing device. Background Art

[0002] After the stone is mined, it needs to be crushed to facilitate transportation and subsequent processing. However, a lot of dust will be generated during the crushing process. However, traditional stone crushing devices are not evenly dust-proof. If workers are in a dusty environment for a long time, it will cause great harm to their health.

[0003] The patent website discloses a stone crushing device with dustproof function (Announcement No.: CN 212493912U), which belongs to the technical field of crushing devices. A stone crushing device with dustproof function includes a bottom plate, a control table is fixedly connected to the top of the bottom plate, a crushing box fixedly connected to the top of the control table is plugged, a feed port is provided on the top of the crushing box, and two sealing plates are hingedly connected between the front and back of the feed port. In this utility model, a water spray pipe is connected to a tap water pipe, and tap water will be atomized and sprayed by an atomizing nozzle. The atomized water mist will reduce the dust generated by the crushing, thereby reducing the generation of dust, and the atomizing nozzle on the top of the water spray pipe will wet the crushing wheel, thereby reducing the generation of dust, and the fan will suck the dust generated by the crushing into the air duct, and the clean air will be filtered by the filter element and then transported to the inside of the crushing box, thereby completing the internal circulation filtration and improving the dustproof effect of the device.

[0004] The above technology can improve the dust-proof effect of the device, but it cannot control the size of the crushed stone when crushing the stone, which brings inconvenience to the work. At the same time, dust removal needs to pass through the filter assembly. Dust accumulates in the filter assembly and the equipment needs to be disassembled regularly to clean or replace the filter assembly, which increases the workload; therefore, there is room for improvement. Utility Model Content

[0005] The utility model provides an efficient stone crushing device to solve the problems raised in the background technology.

[0006] In order to solve the above problems, the utility model provides an efficient stone crushing device, including a crushing box and a dust removal box, a feeding port is arranged on the top of the crushing box, and two baffles for sealing the feeding port are arranged in the feeding port through a torsion spring and a hinge, three crushing rollers are vertically arranged on one side of the crushing box, the three crushing rollers are driven to rotate in the crushing box by a motor, a plurality of first crushing teeth are fixedly arranged on the surfaces of the three crushing rollers, a crushing plate opposite to the three crushing rollers is movably arranged in the crushing box, and the crushing plate is provided with a crushing surface inclined downward, a plurality of second crushing teeth are arranged on the crushing surface which are staggered with the first crushing teeth, a hydraulic telescopic rod is connected to the back side surface of the crushing plate away from the crushing surface, and the hydraulic telescopic rod is fixedly installed in the crushing box, A lower feeding port is provided in the crushing box below the crushing roller and the crushing plate, an air outlet chamber connected to the lower feeding port is provided in the crushing box on the left side of the lower feeding port, and a dust outlet chamber connected to the lower feeding port is provided on the right side of the lower feeding port, a collecting chamber is provided at the bottom of the crushing box below the lower feeding port, an auger conveyor is connected in the collecting chamber, and the outlet of the auger conveyor is located outside the crushing box, an air inlet box connected to the air outlet chamber is provided outside the crushing box, and a first fan is provided in the air inlet box, the dust removal box is fixedly installed on the outside of the crushing box, and the dust outlet chamber in the crushing box is connected to the inside of the dust removal box, a second fan is provided on the opposite side of the dust removal box to the dust outlet chamber, and a protective mesh cover is provided outside the second fan, and a bucket-shaped dust outlet is provided at the bottom of the dust removal box.

[0007] Preferably, the bottom side of the air outlet cavity is inclined, and the lower end is located at the discharge port.

[0008] Preferably, the bottom side of the dust outlet chamber is inclined, and the lower end is located at the discharge port.

[0009] Preferably, a plurality of guide plates which are inclined downward and staggered with each other are provided in the dust removal box, and the length of the guide plates is smaller than the inner width of the dust removal box and larger than half of the inner width of the dust removal box.

[0010] Preferably: a transparent dust collecting box is slidably connected to the dust discharge port at the bottom of the dust removal box.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] 1. When feeding into the crushing box, the stone presses down on the two baffles, which are pressed downward and separated to open the feed port, allowing the stone to enter the crushing box. After the feeding is completed, the two baffles rebound upward under the action of the torsion spring, blocking the feed port on the top of the crushing box to prevent the stone from splashing and dust from being dispersed during crushing.

[0013] 2. The distance between the crushing plate and the three crushing rollers can be adjusted by the hydraulic telescopic rod, so as to control the size of the stone crushing. At the same time, since the crushing surface of the crushing plate is inclined, the first crushing teeth in the top crushing roller cooperate with the second crushing teeth on the upper part of the crushing plate to complete the coarse powder of the stone. Then the stone falls to the crushing roller in the middle, and then cooperates with the middle of the crushing plate for medium powder. Finally, the crushing roller at the bottom cooperates with the lower end of the crushing plate for fine powder. The integrated three-step crushing can improve the crushing efficiency.

[0014] 3. External air is introduced into the air inlet box through the first fan in the air inlet box, and then sent into the air outlet chamber to blow air on the dust and stones falling through the discharge port. Since the stones are heavier, they fall directly into the collecting chamber through the discharge port. The dust generated during crushing and the dust adhering to the surface of the stones enter the dust outlet chamber under the blowing of the airflow. At this time, the second fan in the dust removal box is started to generate suction, and the dust in the dust outlet chamber is sucked into the dust removal box, and then the dust is guided into the dust collecting box in conjunction with the guide plates that are inclined downward and staggered with each other, so as to achieve the dust removal effect. The setting of the dust collecting box facilitates the cleaning of the collected dust and improves work efficiency.

[0015] 4. The crushed stone in the aggregate cavity can be quickly guided out of the crushing box through the auger conveyor, and then discharged from the discharge port, so that the material discharge is fast and the material discharge blockage is prevented. At the same time, by controlling the speed of the auger conveyor, the material discharge speed can be controlled to improve the convenience of work. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3In the present embodiment, an efficient stone crushing device comprises a crushing box 1 and a dust removal box 2. A feed port 3 is arranged on the top of the crushing box 1, and two baffles 31 for movably sealing the feed port 3 are arranged in the feed port 3 through a torsion spring and a hinge. Three crushing rollers 4 are vertically arranged on one side of the crushing box 1. The three crushing rollers 4 are driven to rotate in the crushing box 1 by a motor 41. A plurality of first crushing teeth 42 are fixedly arranged on the surfaces of the three crushing rollers 4. A crushing plate 5 opposite to the three crushing rollers 4 is movably arranged in the crushing box 1, and the crushing plate 5 is provided with a crushing surface 51 inclined downward, and a plurality of second crushing teeth 52 are arranged in the crushing surface 51 which are staggered with the first crushing teeth 42. A hydraulic telescopic rod 53 is connected to the back side of the crushing plate 5 away from the crushing surface 51, and the hydraulic telescopic rod 53 is fixedly installed in the crushing box 1. The crushing rollers 4 in the crushing box 1 are located A lower feeding port 11 is provided below the crushing plate 5, an air outlet chamber 71 connected to the lower feeding port 11 is provided on the left side of the lower feeding port 11 in the crushing box 1, and a dust outlet chamber 21 connected to the lower feeding port 11 is provided on the right side of the lower feeding port 11, a collecting chamber 12 is provided at the bottom of the crushing box 1 below the lower feeding port 11, an auger conveyor 6 is connected to the collecting chamber 12, and the outlet 61 of the auger conveyor 6 is located outside the crushing box 1, an air inlet box 7 connected to the air outlet chamber 71 is provided outside the crushing box 1, and a first fan 72 is provided in the air inlet box 7, the dust removal box 2 is fixedly installed on the outside of the crushing box 1, and the dust outlet chamber 21 in the crushing box 1 is connected to the inside of the dust removal box 2, a second fan 22 is provided on the opposite surface of the dust removal box 2 to the dust outlet chamber 21, and a protective mesh cover 23 is provided outside the second fan 22, and a bucket-shaped dust outlet 24 is provided at the bottom of the dust removal box 2.

[0024] Through the above technical solution: before use, the crushing plate 5 is driven to move in the crushing box 1 by the extension and contraction of the hydraulic telescopic rod 53, and the distance between the crushing surface 51 in the crushing plate 5 and the three crushing rollers 4 can be adjusted, so as to control the size of the stone after crushing. After the adjustment is completed, the crushing box 1 is loaded with materials, and the stone presses down the two baffles 31 by its own weight. The two baffles 31 are pressed downward and separated to open the feed port 3, so that the stone enters the crushing box 1. After the feeding is completed, the two baffles 31 rebound upward under the action of the torsion spring, and the crushed stone is crushed. The feed port 3 at the top of the box 1 is blocked to prevent the splashing of stones and the dispersion of dust during crushing. After the stones enter the crushing box 1, the motor 41 drives the three crushing rollers 4 to rotate synchronously. Since the crushing surface 51 of the crushing plate 5 is inclined, the first crushing teeth 42 in the top crushing roller 4 cooperate with the second crushing teeth 52 on the upper part of the crushing surface 51 to complete the coarse powder of the stones. Then the stones fall to the crushing roller 4 in the middle, and then cooperate with the middle part of the crushing surface 51 for medium powder. Finally, the stones pass through the crushing roller 4 at the bottom and cooperate with the crushing surface 51 to complete the coarse powder. The end is finely ground, and the integrated three-step crushing can improve the crushing efficiency. The crushed stone after the stone is crushed and the dust generated during the crushing go down into the discharge port 11. At this time, the first fan 72 in the air inlet box 7 introduces external air into the air inlet box 7, and then sends it into the air outlet cavity 71 to blow the dust and crushed stone falling through the discharge port 11. Since the air flow blowing force is weak and the crushed stone is heavy, the crushed stone directly falls into the collecting cavity 12 through the discharge port 11, and the dust generated during the crushing and the dust adhering to the surface of the crushed stone are The dust on the surface enters the dust outlet chamber 21 under the blowing of the air flow. At this time, the second fan 22 in the dust removal box 2 is started to generate suction, and the dust in the dust outlet chamber 21 is sucked into the dust removal box 2, thereby completing the dust removal with high dust removal efficiency. When unloading, the auger conveyor 6 works to quickly guide the crushed gravel in the aggregate chamber 12 out of the crushing box 1, and then discharged from the discharge port 61, so that the unloading is fast and the unloading is prevented from being blocked. At the same time, by controlling the rotation speed of the auger conveyor 6, the unloading speed can be controlled to improve the convenience of work.

[0025] Preferably, the bottom side of the air outlet cavity 71 is inclined, and the lower end is located at the discharge port 11 .

[0026] Through the above technical solution, after the crushed stones in the discharge port 11 fall into the air outlet cavity 71 , they can fall back into the discharge port 11 along the inclined lower edge under the blowing of the airflow and enter the collecting cavity 12 .

[0027] Preferably, the bottom side of the dust outlet chamber 21 is inclined, and the lower end is located at the discharge port 11 .

[0028] Through the above technical scheme, after the stones in the discharge port 11 fall into the dust outlet chamber 21, the crushed stones can be prevented from entering the dust removal box 2 under the influence of the air flow blown out of the air outlet chamber, so that the stones fall back to the discharge port 11 along the inclined lower edge and enter the collection chamber 12.

[0029] Preferably, a plurality of guide plates 25 which are tilted downward and staggered with each other are provided in the dust removal box 2 , and the length of the guide plates 25 is smaller than the inner width of the dust removal box 2 and larger than half of the inner width of the dust removal box 2 .

[0030] Through the above technical solution, the guide plate 25 can guide the dust in the airflow downward, so that the dust falls to the bottom of the dust removal box 2 after settling. Through the staggered arrangement, the dust settled at the bottom of the dust removal box 2 can be prevented from flying upward under the influence of the airflow, thereby improving the dust removal effect.

[0031] Preferably, a transparent dust collecting box 26 is slidably connected to the dust outlet 24 at the bottom of the dust removal box 2 .

[0032] Through the above technical solution, the dust collecting box 26 is used to collect dust discharged from the dust outlet 24 at the bottom of the dust removal box 2. The transparent setting of the dust collecting box 26 is convenient for observing the collection of dust in the dust collecting box 26, and then convenient for timely cleaning of the dust collecting box 26.

[0033] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
