DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-Figure 3 , Figure 7 and Fig.11An environmentally friendly building stone crushing equipment includes a shell 1. A crushing chamber 11 and a dust removal chamber 12 are respectively arranged inside the shell 1 along the vertical direction from top to bottom. An exhaust port 14 is arranged at the upper part of the shell 1. The dust removal chamber 12 generates flowing air from bottom to top along the vertical direction of the shell 1. The flowing air passes through the crushing chamber 11 from the dust removal chamber 12 and is discharged from the exhaust port 14. When the building stone enters the crushing chamber 11 for crushing, the rising flowing air takes away the dust in the crushed building stone and discharges it from the exhaust port 14. The flowing air performs the first dust removal on the building stone in the crushing chamber 11.

[0030] A feed port 13 is provided on the side of the crushing chamber 11, and the building stones to be crushed are put into the crushing chamber 11 through the feed port 13. A crushing unit 2 is provided below the feed port 13, and the crushing unit 2 can crush the building stones. The crushing unit 2 includes a crushing roller 21 and a first rotation driver 22. The first rotation driver 22 is a servo motor. Two crushing rollers 21 are provided. The two crushing rollers 21 are arranged in parallel at the bottom of the crushing chamber 11. A gap is left between the two crushing rollers 21. The tangential forces at the opposite ends of the two crushing rollers 21 are both vertically downward. The first rotation driver 22 is arranged at the end of the crushing roller 21, and the first rotation driver 22 is used to drive the crushing roller 21 to rotate. The building stones put into the crushing chamber 11 from the feed port 13 eventually fall into the gap between the two crushing rollers 21, so that the two crushing rollers 21 can crush the building stones. Dust will be generated in the crushing process, and the dust removal chamber 12 can generate an upward airflow from bottom to top. The airflow in the dust removal chamber 12 passes through the gap between the two crushing rollers 21, and the flowing airflow drives the dust to the discharge port 14, thus completing the preliminary dust removal of the building stones. A dust removal unit 5 is arranged in the dust removal chamber 12, and the dust removal unit 5 can perform secondary dust removal on the building stones located in the dust removal chamber 12. After two dust removal operations, it can be ensured that the surface of the crushed building stones is clean, meeting the construction requirements.

[0031] Reference Figure 3 : A partition unit 3 is provided in the crushing chamber 11, which can divide the crushing chamber 11 into a first cavity and a second cavity. The first cavity and the second cavity are arranged from top to bottom in the vertical direction. The building stones falling into the crushing chamber 11 are crushed in the second cavity. When the partition unit 3 is in an open state, the first cavity and the second cavity are connected to each other. When the partition unit 3 is in a closed state, the first cavity and the second cavity are isolated from each other.

[0032] The crushing unit 2 is located in the second cavity, and the partition unit 3 is used to control the stock of building stones in the second cavity to ensure that the crushing roller 21 can crush the building stones normally and avoid the crushing roller 21 being stuck due to too much building stones in the second cavity. At the same time, if there are too many building stones piled up in the second cavity, the crushing roller 21 will further crush some building stones that meet the size when crushing the building stones. The final output of building stones is too small and cannot be used, and most of the building stones to be crushed have dust attached to the outside. Controlling the stock of building stones in the second cavity can ensure that the air in the dust removal chamber 12 can rise through the gap between the two crushing rollers 21, thereby realizing the first dust removal operation of the building stones and completing the preliminary dust removal of the building stones.

[0033] Reference Figure 2 : A monitoring unit 4 for monitoring the stock of building stones in the second cavity is arranged on one side of the second cavity. The monitoring unit 4 uses visual monitoring to monitor the stock of building stones in the second cavity. The building stones entering the second cavity are gradually accumulated. When the monitoring unit 4 does not detect the accumulated building stones, the partition unit 3 is in an open state. When the monitoring unit 4 detects the accumulated building stones, the partition unit 3 is closed.

[0034] The monitoring unit 4 includes a camera, which is horizontally arranged on the side wall of the second cavity, and the camera monitors the accumulation of building stones in the second cavity. In the process of crushing building stones by the equipment, the building stones to be crushed are continuously put in from the feed port 13, and finally all the building stones will be accumulated in the second cavity, that is, all the building stones are accumulated on the two crushing rollers 21. If there is too much accumulation, the crushing roller 21 will inevitably get stuck, which will cause the first rotary drive 22 to be overloaded and damaged. After the camera is set, the camera monitors the building stones accumulated in the second cavity. When the amount of building stones put into the crushing cavity 11 is greater than the amount discharged after crushing by the crushing unit 2, the building stones will accumulate on the crushing roller 21. The camera monitors the continuously accumulated building stones. When the camera detects the accumulated building stones, the separation unit 3 starts to isolate the first cavity and the second cavity, and the building stones to be crushed put in from the feed port 13 cannot enter the second cavity, ensuring the crushing effect of the crushing roller 21.

[0035] Reference Figure 1-Figure 3: A dust removal unit 5 capable of blowing outside air into the housing 1 is provided in the dust removal chamber 12, and a dust suction unit 6 capable of extracting air from the crushing chamber 11 is provided on the discharge port 14. The dust removal unit 5 and the dust suction unit 6 jointly guide the air flow direction in the housing 1. The dust removal unit 5 blows outside air into the housing 1, and the dust suction unit 6 extracts the air from the crushing chamber 11. The air blown into the housing 1 by the dust removal unit 5 first enters the dust removal chamber 12, and the dust suction unit 6 extracts the air from the crushing chamber 11, so that the air in the dust removal chamber 12 can be replenished into the crushing chamber 11, so that the air in the housing 1 can flow from bottom to top.

[0036] The dust suction unit 6 includes an exhaust fan 61, which is arranged on the exhaust port 14. The exhaust fan 61 is used to extract the air in the crushing chamber 11, and the dust floating in the air is extracted with the air. The output end of the exhaust fan 61 is connected to a cloth belt dust collector. The exhaust fan 61 extracts the air mixed with dust and discharges it into the cloth belt dust collector, so that the dust can be collected.

[0037] Reference Figure 5-Figure 9 The dust removal unit 5 includes a rotating shell 51 rotatably arranged in the dust removal chamber 12, and air vents are evenly opened on the rotating shell 51. The upper opening diameter of the rotating shell 51 is larger than the lower opening diameter. The dust removal unit 5 also includes an air supply unit 52 arranged around the rotating shell 51. The air supply unit 52 is preferably a hair dryer. The air supply unit 52 blows external air into the rotating shell 51 through the air vents. The rotating shell 51 is used to receive the building stones that are crushed and dropped from the crushing chamber 11, and the building stones in the rotating shell 51 are subjected to secondary dust removal through the air supply unit 52.

[0038] A plurality of abutment plates 511 are fixedly disposed on the inner side wall of the rotating shell 51 . The abutment plates 511 are arranged around the axis of the rotating shell 51 . When the rotating shell 51 rotates, the abutment plates 511 are driven to rotate synchronously. When the building stones fall into the rotating shell 51, since the rotating shell 51 is in a rotating state, the building stones roll on the inner wall of the rotating shell 51. Since the air supply unit 52 can blow air into the rotating shell 51 through the air holes on the rotating shell 51, the building stones can be cleaned more comprehensively during the rolling process. The abutment plate 511 arranged on the rotating shell 51 has an intercepting effect on the building stones, that is, the building stones will roll after falling into the rotating shell 51, but at this time the falling speed of the building stones is faster, and the abutment plate 511 rotates synchronously with the rotating shell 51. When the abutment plate 511 intercepts the building stones, the rotational force of the abutment plate 511 acts on the building stones, so that the friction between the abutment plate 511 and the building stones increases, thereby reducing the falling speed of the building stones. In this way, the time that the building stones stay in the rotating shell 51 is increased, so that the air supply unit 52 has a longer cleaning time for the building stones, thereby ensuring the dust removal effect of the second dust removal operation.

[0039] A driving unit 53 for driving the rotating shell 51 to rotate is disposed at the bottom of the rotating shell 51. The driving unit 53 includes a second rotating driver 531, a first gear 532 and a gear ring 533. The gear ring 533 is fixedly disposed at the bottom of the rotating shell 51. The first gear 532 is rotatably disposed at one side of the gear ring 533 and meshes with the gear ring 533. The second rotating driver 531 is preferably a servo motor, and the first gear 532 is fixedly mounted at the output end of the second rotating driver 531. When the second rotating driver 531 is started, the second rotating driver 531 can drive the gear ring 533 to rotate through the first gear 532, so that the rotating shell 51 fixedly connected to the gear ring 533 rotates.

[0040] Reference Fig.11 A guide plate 54 is obliquely arranged on the upper part of the rotating shell 51. The guide plate 54 is used to receive the building stones after the crushing chamber 11 has completed the crushing. The guide plate 54 guides the building stones to the edge side of the upper opening of the rotating shell 51. Through holes are evenly opened on the guide plate 54, so that the flowability of the air in the dust removal chamber 12 when entering the crushing chamber 11 can be improved.

[0041] The crushed building stones move to the edge side of the rotating shell 51 under the guidance of the guide plate 54. At this time, the crushed building stones fall from the guide plate 54 and fall on the inner wall of the rotating shell 51, so as to extend the retention time of the building stones entering the rotating shell 51 in the rotating shell 51, so that the building stones in the rotating shell 51 can obtain more dust removal time.

[0042] Reference Figure 1 , Figure 2 , Figure 7 and Fig. 9 : The partition unit 3 includes a partition plate 31 rotatably arranged in the crushing chamber 11. Two partition plates 31 are arranged, and the two partition plates 31 rotate synchronously. When the two partition plates 31 approach and contact each other, the crushing chamber 11 is divided into a first cavity and a second cavity. When the two partition plates 31 move away from each other, the first cavity and the second cavity are reconnected.

[0043] A rotating unit 32 for driving the partition plate 31 to rotate is provided on the side of the partition plate 31. The rotating unit 32 includes a third rotation driver 321 and a transmission assembly 322. The third rotation driver 321 is preferably a servo motor. Since there are two partition plates 31, the transmission assembly 322 is arranged between the two partition plates 31, and the third rotation driver 321 is arranged at the end of one of the partition plates 31. The third rotation driver 321 is used to drive the partition plate 31 to rotate and make the other partition plate 31 rotate synchronously under the action of the transmission assembly 322. The rotation directions of the two partition plates 31 are always opposite, so that the two partition plates 31 are close to each other in a closed state or away from each other in an open state. There are two groups of transmission components 322, each group of transmission components 322 includes a second gear 3221, two synchronous wheels 3222 and a synchronous belt 3223, the two synchronous wheels 3222 are arranged horizontally, one of the synchronous wheels 3222 is fixedly set at the end of the partition plate 31, the synchronous wheel 3222 rotates synchronously with the partition plate 31, the two synchronous wheels 3222 are connected by the synchronous belt 3223, the second gear 3221 is fixedly set on the synchronous wheel 3222 that is not connected to the partition plate 31, and the second gears 3221 in the two groups of transmission components 322 are meshed with each other. After adopting this structural form, after the third rotation driver 321 is started, the transmission of the transmission component 322 can make the two partition plates 31 rotate synchronously.

[0044] Reference Figure 7 : The air outlet groove 33 is provided on the side wall of the second cavity. When the two partition plates 31 are close to and in contact with each other, the crushing cavity 11 is divided into the first cavity and the second cavity, and the air outlet groove 33 is in an open state. When the two partition plates 31 are away from each other, the first cavity and the second cavity are connected to each other, and the air outlet groove 33 is in a closed state. A switch valve 34 for discharging the building stones in the dust removal cavity 12 is provided at the bottom of the dust removal cavity 12. When the air outlet groove 33 is opened, the switch valve 34 is in a closed state.

[0045] The feed port 13 is rotatably connected with a rotating plate 15. When feeding through the feed port 13, the rotating plate 15 is rotated to open the feed port 13. The switch valve 34 is opened only when the air outlet slot 33 is in a closed state to discharge the building stones stored in the lower part of the rotating shell 51. When the switch valve 34 is opened, the dust suction unit 6 sucks out the air in the crushing chamber 11, so that more air is needed to be added into the crushing chamber 11, ensuring that the rising thrust of the rising airflow in the outer shell 1 remains constant after the switch valve 34 is opened. After the two partition plates 31 separate the crushing chamber 11 into the first chamber and the second chamber, the air supply unit 52 is in operation, and the dust suction unit 6 continues to operate. The dust suction unit 6 discharges the gas in the first chamber and simultaneously rotates the rotating plate 15 to generate a gap between the rotating plate 15 and the feed port 13, thereby sucking outside air into the first chamber. At the same time, the air supply unit 52 blows outside air into the dust removal chamber 12, and the air outlet slot 33 opens to discharge the gas in the dust removal chamber 12, thereby achieving the effect of secondary dust removal. The air outlet slot 33 is opened and closed by the rotation of the partition plate 31, thereby avoiding the use of a valve body to control the opening and closing of the air outlet slot 33 alone, thereby reducing the manufacturing cost.

[0046] Reference Figure 4 and Figure 7 : A limiting assembly 35 is provided on the partition plate 31 to limit the rotation of the partition plate 31.

[0047] The limiting assembly 35 includes a guide groove 351 and a guide block 352. The guide groove 351 is an arc-shaped structure and is opened on the side wall of the second cavity. The guide block 352 is fixedly arranged on the side wall of the partition plate 31, and the guide block 352 slides with the guide groove 351 along the extension direction of the guide groove 351. The center of the guide groove 351 coincides with the rotation center of the partition plate 31. When the partition plate 31 is in the open state, the guide block 352 moves to one end of the guide groove 351, and when the partition plate 31 is in the closed state, the guide block 352 moves to the other end of the guide groove 351. At this time, the gravity generated by the building stones thrown into the partition plate 31 from the feed port 13 will not affect the third rotary driver 321 in the rotating unit 32. This is because the guide block 352 has reached one end of the guide groove 351, and the end of the guide groove 351 has a limiting effect on the guide block 352, which is conducive to extending the service life of the rotating unit 32.

[0048] The present invention also provides an environmentally friendly building stone crushing method based on the above-mentioned environmentally friendly building stone crushing equipment, comprising the following steps: S1: Put the stone into the crushing chamber 11 for crushing; S2: Preliminary dust removal operation: The dust removal unit 5 in the preliminary dust removal chamber 12 supplies air to the dust removal chamber 12, so that the airflow in the dust removal chamber 12 flows from bottom to top into the crushing chamber 11 and is discharged from the discharge port 14. When the airflow passes through the crushing chamber 11, the dust contained in the crushed building stones is taken away, thus completing the preliminary dust removal of the building stones; S3: secondary dust removal operation; the crushed building stones enter the dust removal chamber 12, the air supply unit 52 blows the outside air into the dust removal chamber 12, the air outlet slot 33 is opened, and the gas in the dust removal chamber 12 is discharged, thereby realizing the secondary dust removal of the building stones; S4: The building gravel after the secondary dust removal is discharged from the switch valve 34.

[0049] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
