Technical Field
[0001] This utility model relates to the technical field of crushed stone collection devices, specifically to a device for collecting crushed stone from marble used in construction. Background Technology
[0002] Marble processing produces gravel because the raw marble ore needs to undergo crushing and cutting processes. These processes inevitably break some marble into gravel of varying sizes. This gravel still has some use value and can be used as building material for road paving, concrete production, etc. Rational utilization can effectively save resources and improve resource utilization rate.
[0003] In the process of realizing this utility model, the inventors discovered that:
[0004] During the screening and collection of crushed stone, some screening devices shake the crushed stone, causing it to move within the screen plate. At this time, a large amount of dust from the crushed stone is raised and scattered freely in the working environment. If no corresponding dust removal measures are prepared, the dust will be discharged from the equipment and permeate the working environment, which will not only pollute the air but also affect the health of the operators. Summary of the Invention
[0005] In order to solve the problems existing in the prior art, this utility model provides a device for processing and collecting crushed stone for building marble, which can avoid dust from being scattered in the working environment during the screening and collection of crushed stone, thus affecting the health of operators.

[0007] A further improvement to the above technical solution is that: a suction pipe is fixedly connected to the upper inner wall of both the first and second sieve plates on the left side of the front end of the box, and it runs through both the inner and outer parts of the box. The front end of the suction pipe is fixedly connected to the upper and lower parts of the rear side of the outer wall of the extension pipe, respectively.
[0008] In this technical solution, the suction pipe is located on the upper side of screen plate one and screen plate two, maintaining a certain distance, and will not interfere with the suction pipe when screen plate one and screen plate two move up and down.
[0009] A further improvement to the above technical solution is that: a motor is fixedly connected to the right end of the inner wall of the box, which is located below both the first and second sieve plates, and a cam is fixedly connected to the drive end of the motor.
[0010] In this technical solution, the motor acts as an electric drive device, providing rotational power for the cam.
[0011] A further improvement to the above technical solution is that: a fixing plate is fixedly connected to the right end of the inner wall of the box below the motor, and springs are fixedly connected to the front and rear sides of the top of the fixing plate. The other end of the springs is fixedly connected to the front and rear parts of the bottom right side of the screen plate one and the screen plate two, respectively.
[0012] In this technical solution, the spring generates elastic potential energy after being compressed by heavy forces and rebounds, thus providing a buffering effect.
[0013] A further improvement to the above technical solution is that: a concave plate is fixedly connected to the lower side of the inner wall of the dust collection chamber, an isolation cover is provided in the middle of the rear side of the inner wall of the concave plate, a number of through grooves are opened on the outer wall of the isolation cover, a filter screen is fixedly connected to the inner wall of each through groove, a baffle is provided on the lower side of the inner wall of the isolation cover, and the rear end of the baffle is fixedly connected to the rear end of the inner wall of the dust collection chamber.
[0014] In this technical solution, the filter screen has a small mesh size, which ensures the flow of air and water.
[0015] A further improvement to the above technical solution is that: a support base is fixedly connected to the top center of the concave plate, a second motor is fixedly connected to the top of the support base, and the drive end of the second motor is fixedly connected to the front center of the isolation cover;
[0016] In this technical solution, the drive end of motor two is adjusted to rotate at a slow speed, so that the isolation cover can rotate slowly.

[0018] In this technical solution, the water tank has a built-in water pump, and the output end of the water pump is connected to the water pipe.
[0019] A further improvement to the above technical solution is that: a material drop box is provided on the inner wall below the atomizing nozzle at the front end of the dust collection chamber, and a cleaning brush is fixedly connected to the middle of the rear end of the inner wall of the material drop box, with the top of the cleaning brush attached to the bottom of the outer wall of the isolation cover;
[0020] In this technical solution, the bristles of the cleaning brush are made of anti-static material, so the dust swept off is not easily stuck to the bristles.
[0021] Beneficial effects: In this utility model, through the cooperation of a dust collection chamber, support cover, exhaust fan, isolation cover, filter screen, extension pipe, and suction pipe, the dust raised during the screening of crushed stone by sieve plate one and sieve plate two is sucked into the dust collection chamber. When the airflow passes through the filter screen, the dust is filtered onto the surface of the filter screen, thus preventing dust from dispersing into the working environment and affecting the health of operators. Through the cooperation of a concave plate, baffle, support base, motor two, as well as a material drop box, cleaning brush, water tank, water pipe, and atomizing nozzle, the isolation cover rotates at a uniform speed. When the filter screen passes through the cleaning brush, the dust on the surface of the filter screen is swept off and then combined with the water mist sprayed from the atomizing nozzle, falling into the material drop box for collection. This prevents excessive dust accumulation on the surface of the filter screen, which would affect the flow effect of the filter screen. Attached Figure Description

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.
[0030] This utility model is as follows Figures 1 to 6 As shown:
[0031] A device for processing and collecting crushed stone from marble used in construction includes a box body 1. A feed inlet 2 is located on the top right side of the box body 1. Sliding grooves 16 are formed in the middle of the upper and lower sides of the inner wall of the box body 1 at both ends. Connecting rods 12 are slidably connected to the inner walls of the sliding grooves 16. A screen plate 8 is fixedly connected to one end of the two upper connecting rods 12, and a screen plate 9 is fixedly connected to one end of the two lower connecting rods 12. A discharge outlet 3 is formed on the left side of the box body 1, below both screen plates 8 and 9. The discharge outlet 3 is located on the left side of the box body 1, below the discharge outlet 3. A guide frame 4 is fixedly connected. A dust collection chamber 5 is fixedly connected to the top left side of the box body 1. A support cover 19 is fixedly connected to the rear end of the dust collection chamber 5. An exhaust fan 20 is fixedly connected to the inner wall of the rear end of the support cover 19 and penetrates both the inner and outer parts of the support cover 19. An extension pipe 6 is fixedly connected to the middle of the front end of the dust collection chamber 5. Suction pipes 15 are fixedly connected to the upper inner walls of the screen plate 8 and screen plate 9 on the left side of the front end of the box body 1 and penetrate both the inner and outer parts of the box body 1. The front ends of the suction pipes 15 are fixedly connected to the upper and lower parts of the rear side of the outer wall of the extension pipe 6, respectively.
[0032] Motor 13 is fixedly connected to the right side of the inner wall of box 1, below screen 8 and screen 9. Cam 14 is fixedly connected to the drive end of motor 13. Fixing plate 10 is fixedly connected to the right side of the inner wall of box 1, below motor 13. Spring 11 is fixedly connected to the front and rear sides of the top of fixing plate 10. The other end of spring 11 is fixedly connected to the front and rear parts of the bottom right side of screen 8 and screen 9 respectively.
[0033] First, crushed stone is fed into the housing 1 through the feed inlet 2. When the crushed stone falls into the screen plate 8, its weight causes the screen plate 8 to compress the spring 11, which then rebounds, creating a buffering effect. Next, the two motors 13 inside the housing 1 are started, causing their drive ends to rotate the cam 14. When the smaller outer diameter end of the cam 14 rotates to the upper side, it pushes the screen plate 8 and the screen plate 9 upwards respectively. At this time, the connecting rod 12 slides synchronously in the slide groove 16. When the smaller outer diameter end of the cam 14 rotates to the lower side, the screen plate 8 and the screen plate 9 move downwards due to gravity. Then, under the continuous rotation of the cam 14, the screen plate 8 and the screen plate 9 move up and down continuously. The crushed stone inside screen plate 8 will shake, thus creating a vibrating screening effect. Smaller crushed stone particles will pass through the screen holes in screen plate 8 and fall into screen plate 9. Screen plate 9 will then continue to shake the crushed stone. Since the inner diameter of the screen holes in screen plate 9 is smaller than that in screen plate 8, even smaller crushed stone particles will pass through the screen holes in screen plate 9 and finally fall out from the bottom opening of the box 1. The remaining crushed stone will slide under the tilting action of screen plate 8 and screen plate 9 and be discharged from the corresponding discharge port 3, falling into the guide frame 4. It will then be guided along the direction of the guide frame 4 and discharged from different directions. It is only necessary to place containers at the bottom opening of the box 1 and the opening of the guide frame 4 beforehand.
[0034] In this embodiment, a concave plate 22 is fixedly connected to the lower side of the inner wall of the dust collection chamber 5. An isolation cover 25 is provided in the middle of the rear side of the inner wall of the concave plate 22. Several through slots are opened on the outer wall of the isolation cover 25. A filter screen 26 is fixedly connected to the inner wall of each through slot. A baffle 23 is provided on the lower side of the inner wall of the isolation cover 25. The rear end of the baffle 23 is fixedly connected to the rear end of the inner wall of the dust collection chamber 5. A support base 27 is fixedly connected to the middle of the top of the concave plate 22. A second motor 28 is fixedly connected to the top of the support base 27. The drive end of the second motor 28 is fixedly connected to... A water tank 17 is fixedly connected to the bottom rear end of the dust collection chamber 5 at the middle front end of the isolation cover 25. Water pipes 18 are fixedly connected to both ends of the water tank 17. The other ends of the water pipes 18 pass through the inner walls of the concave plate 22 at the left and right ends of the dust collection chamber 5. Atomizing nozzles 21 are fixedly connected to the other ends of the water pipes 18. A material drop box 7 is provided at the inner wall of the dust collection chamber 5 below the atomizing nozzles 21. A cleaning brush 24 is fixedly connected to the middle rear end of the inner wall of the material drop box 7. The top of the cleaning brush 24 is attached to the bottom of the outer wall of the isolation cover 25.
[0035] While the crushed stone is being screened and collected, the exhaust fan 20 is activated to create negative pressure at its input end, drawing in airflow. This airflow passes through multiple filters 26 on the outer wall of the isolation cover 25, drawing the airflow into the dust collection chamber 5. The extension pipe 6 and the suction pipe 15 further extend the negative pressure range of the exhaust fan 20, drawing in dust generated during the screening of the first and second sieve plates 8 and 9 through the suction pipe 15. The dust then follows the airflow direction, flowing along the extension pipe 6 into the dust collection chamber 5, and then through the filters 26. As the airflow passes through the filters 26, the dust is filtered onto the surface of the filters 26. The filtered airflow then passes through the exhaust fan 20 and is discharged. The airflow then passes through the filters 26... Simultaneously, motor 28 can be started, causing its drive end to slowly rotate the isolation cover 25. During the rotation of the isolation cover 25, when the filter screen 26 passes through the cleaning brush 24 in sequence, it will rub against the cleaning brush 24. Subsequently, the cleaning brush 24 will sweep off the dust on the surface of the filter screen 26, preventing the dust from accumulating too much on the surface of the filter screen 26 and affecting the flow effect of the filter screen 26. At the same time, the water pump in the water tank 17 is started, causing the water pump to draw water. Then, the water is delivered to the atomizing nozzle 21 through the water pipe 18 connected to the water pump output end, spraying out water mist. The dispersed water mist will then combine with the swept-off dust, causing the dust to fall into the dust collection box 7. Afterwards, the dust collection box 7 can be pulled out from the dust collection chamber 5 to clean the dust.
[0036] The working principle of this utility model:
[0037] First, crushed stone is fed into the housing 1 through the feed inlet 2. When the crushed stone falls onto the screen plate 8, its weight compresses the spring 11 below. The spring 11 rebounds after being stressed, acting as a buffer. Then, the two motors 13 inside the housing 1 are started. Their drive ends drive the cam 14 to rotate. When the end of the cam 14 with the smaller outer diameter turns upward, it pushes the screen plate 8 and the screen plate 9 to move upward synchronously. The connecting rod 12 slides in the slide groove 16 to ensure stable movement. When the end of the cam 14 with the smaller outer diameter turns downward, the screen plate 8 and the screen plate 9 fall back under the action of gravity. As the cam 14 continues to rotate, the screen plate 8 and the screen plate 9 continuously move upward. The reciprocating motion causes the crushed stone in the screen plate 8 to shake, thus achieving vibrating screening. Smaller crushed stone particles fall through the screen holes of the screen plate 8 and onto the screen plate 9. The screen plate 9 continues to shake and screen. Since the screen holes in the screen plate 9 are smaller than those in the screen plate 8, even smaller crushed stone particles can pass through the screen holes of the screen plate 9 and fall from the bottom opening of the box 1. Other crushed stone particles that have been screened slide under the tilting action of the screen plate 8 and the screen plate 9 and are discharged from the corresponding discharge port 3. Guided by the guide frame 4, they flow out from different directions. Simply placing containers at the bottom opening of the box 1 and the opening of the guide frame 4 is enough to complete the crushed stone collection.
[0038] During the crushed stone screening and collection process, the exhaust fan 20 is activated, generating negative pressure at its input end. Airflow within the dust collection chamber 5 passes through the filter screen 26 on the outer wall of the isolation cover 25 and is drawn into the exhaust fan 20. Through the extension pipe 6 and the suction pipe 15, the negative pressure range increases, drawing in dust generated during the screening of crushed stone by the first screen plate 8 and the second screen plate 9. The dust, carried by the airflow, enters the dust collection chamber 5 through the extension pipe 6. As it passes through the filter screen 26, the dust is intercepted on its surface. The filtered airflow is then discharged from the exhaust fan 20. To prevent the filter from... When the filter screen 26 becomes clogged, the second motor 28 is started, which drives the isolation cover 25 to rotate slowly. During the rotation, the filter screen 26 passes by the cleaning brush 24 in sequence. The friction between the two causes the cleaning brush 24 to sweep off the dust on the surface of the filter screen 26. At the same time, the water pump in the water tank 17 starts to pump water, which is delivered to the atomizing nozzle 21 through the water pipe 18. The sprayed water mist combines with the swept-off dust, causing the dust to fall into the material box 7. After the screening work is completed, the material box 7 can be removed to clean the dust, ensuring a clean environment and smooth equipment operation throughout the screening process.
