[0024] First rotating rod, the first rotating rod is symmetrically arranged on the outer wall of the first motor, and the outer wall of the first rotating rod is rotatably connected to the outer wall of the first motor. When the first telescopic rod drives the first cover to move inward, the first rotating rod rotates, so that the cleaning rod on the first cover is far away from the bottom of the inner wall of the box body, and then when it moves to the innermost side of the box body, the first rotating rod vertically lowers the cleaning rod.

Elastic rods are symmetrically arranged at one end of the U-shaped rod away from the limiting block, and one end of the elastic rod away from the U-shaped rod is connected to the outer wall of the brush plate. Since the U-shaped rod on the limiting block holds the elastic rod in place, the elastic rod is stretched and extended. During the process of the second telescopic column extending, the cover plate moves outwards, so the brush plate remains in an outwardly open state under the elastic pulling force of the elastic rod.

[0042] The beneficial effects of the present invention are as follows:

[0043] 1. The present invention sets up a cleaning mechanism, enabling the cleaning brush to clean the bottom of the box body and the cleaning rod to clean the side of the box body, accelerating the discharging speed of powdered abrasive and fine abrasive. The first rotating rod and the second rotating rod can freely expand and contract, ensuring that the bottom of the cleaning rod always remains in contact with the bottom of the inner wall of the box body when lowered, maintaining the discharging speed, reducing the dust content in the box body, and cleaning the dust adhering to the inner wall of the box body.

[0044] 2. The present invention sets up a buffering mechanism to buffer the speed of the abrasive to a certain extent and recycle the dust adhering to the inner wall. The second telescopic rod reciprocates, slowly approaching the feeding port and then quickly retracting, making the buffering component move in the opposite direction to the flowing direction of the abrasive, thus forming an opposing buffer, avoiding the dust contained in the abrasive from adhering to the inner wall of the box body. Over time, this would cause the dust content on the inner wall of the equipment to be too high. Through separate collection, it reduces the dust flying in the equipment and the poor working environment.

[0045] 3. The present invention sets up a screening component. The scraper reciprocates on the sieve plate. Larger abrasive particles are directly discharged through the square holes. The mixed abrasive is intercepted and ground by the scraper, splitting the mixed abrasive while slowing down the speed of the abrasive and further screening it, avoiding agglomeration or the directly discharging of precision abrasive moving too fast with the abrasive, and improving the screening accuracy.

[0046] 4. The present invention sets up an ash collection component. Since the U-shaped rod on the limit block holds the elastic rod in place, causing the elastic rod to be stretched and extended. During the extension process of the second telescopic column, the cover plate moves outward. Therefore, the brush plate remains in an outward-opening state under the elastic pull of the elastic rod. When the second telescopic column retracts, the force on the elastic rod from the limit block and the U-shaped rod decreases, causing the brush plate to contact the inner wall of the box body and sweep the dust on the inner wall into the cover plate, concentrating the dust attached to both sides above the sieve plate, effectively reducing the residence of dust on the inner wall of the box body, lowering the dust content in the box body, and separately recycling the dust, reducing the work of further screening and the cleaning scope of the staff.

Specific embodiments

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limiting the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0058] Example 1, please refer to Figures 1 - 5 , a technical solution provided by the present invention: a description of an abrasive particle grading and screening device is as follows.

[0059] Including:

[0060] A box body 1, vibrators 2 are uniformly arranged at the four corners of the outer wall of the box body 1, a cover plate 3 is installed on the top of the box body 1, and a feeding port 4 is opened on the top of the cover plate 3;

[0061] The sieve plate 9 is symmetrically arranged above and below and installed on the inner wall of the box body 1 in an inclined manner.

[0062] The buffer mechanism 8 is installed on the inner wall of the box body 1, and the bottom of the buffer mechanism 8 is in contact with the top of the sieve plate 9.

[0063] The abrasive particle grading and screening device further includes:

[0064] The steering mechanism 6 is arranged below the sieve plate 9, and there are two steering mechanisms 6. The steering mechanism 6 is used to perform air flow impact on the sieve plate 9 when it is blocked to clean it.

[0065] The discharge chute 5 is evenly arranged at one end of the outer wall of the box body 1 away from the feed inlet 4.

[0066] The cleaning mechanism 7 is arranged below the buffer mechanism 8 and is in contact with the bottom of the inner wall of the box body 1.

[0067] During operation, the feeding device conveys the abrasive through the feed inlet 4 into the interior of the box body 1. The vibrator 2 is turned on to vibrate the box body 1 to screen the abrasive. There are two groups of sieve plates 9 with different precisions. The abrasive intercepted after passing through the sieve plate 9 is finally discharged through the discharge chute 5. The buffer mechanism 8 intercepts the intercepted abrasive, slows down the moving speed of the abrasive, enables the fine particles in the abrasive to be completely screened, and at the same time centrally collects the dust adhering to the inner wall of the box body 1. The steering mechanism 6 is externally connected to a blowing device. When the sieve plate 9 is blocked, the blowing device can blow air flow towards the holes of the sieve plate 9 and clean the sieve plate 9 in cooperation with the vibration to avoid shutdown. Finally, the smallest particles of the abrasive fall to the bottom of the box body 1, and the cleaning mechanism 7 discharges them completely.

[0068] The buffer mechanism 8 includes:

[0069] The second telescopic rod 801, one end of the second telescopic rod 801 is installed on the side of the inner wall of the box body 1 away from the feed inlet 4, and the other end of the second telescopic rod 801 is installed with a second mounting plate 802.

[0070] The second motor 803 is installed at the end of the second mounting plate 802 away from the second telescopic rod 801.

[0071] The screening component 804 is installed on the outer wall of the second motor 803.

[0072] The dust collecting component 805 is symmetrically installed on both sides of the screening component 804. The dust collecting component 805 is used to separately collect the dust adhering to the inner wall of the box body 1.

[0073] When the abrasive enters the upper sieve plate 9, due to the inclined setting of the sieve plate 9 and the vibration of the vibrator 2, the abrasive can be spread on the sieve plate 9 for screening. At the same time, it also causes the moving speed of the piled-up abrasive to be too fast, resulting in the abrasive with a smaller precision being discharged following the large abrasive before being fully screened. At this time, the second telescopic rod 801 drives the screening assembly 804 and the dust collection assembly 805 on the second motor 803 to approach the feed inlet 4, buffer the speed of the abrasive to a certain extent, and recover the dust adhering to the inner wall. The second telescopic rod 801 reciprocates, slowly approaches the feed inlet 4 and then quickly retracts, making the buffer assembly opposite to the flow direction of the abrasive, thus forming an opposing buffer to prevent the dust contained in the abrasive from adhering to the inner wall of the box body 1. Over time, it will cause the dust content on the inner wall of the equipment to be too high. Through separate collection, the dust flying in the equipment is reduced, resulting in a poor working environment.

[0074] The steering mechanism 6 includes:

[0075] The air pipe 601 is uniformly arranged at the bottom of the sieve plate 9. The outer wall of the air pipe 601 is rotatably connected to the inner wall of the box body 1. Air outlet holes 605 are formed at the bottom of the air pipe 601;

[0076] The special-shaped block 602 is installed at one end of the air pipe 601. Clamping blocks 606 are symmetrically arranged on the outer wall of the special-shaped block 602;

[0077] The conveyor belt 603, the inner wall of the conveyor belt 603 is clamped with the inner wall of the special-shaped block 602. One end of the conveyor belt 603 is provided with a driving block 604, and the driving block 604 is installed on the outer wall of the box body 1.

[0078] The air pipe 601 is externally connected to a blowing device. When the sieve plate 9 is working normally, the air outlet holes 605 of the air pipe 601 face downward. When the sieve plate 9 is blocked by abrasive fragments, the driving block 604 drives the conveyor belt 603 to rotate, causing the special-shaped block 602 clamped with the conveyor belt 603 to rotate, and then rotating a certain angle for multiple groups of air pipes 601 at the same time so that the air outlet holes 605 are aligned with the sieve plate 9. Then, the sieve plate 9 is subjected to air flow impact through the externally connected blowing device to clean the fragments, eliminating the need for manual cleaning by workers, reducing labor and also reducing downtime.

[0079] The cleaning mechanism 7 includes:

[0080] The first telescopic rod 701, one end of the first telescopic rod 701 is installed below the inner wall of the box body 1 near the discharge chute 5, and the other end of the first telescopic rod 701 is provided with a first mounting plate 702;

[0081] The first motor 703, the first motor 703 is arranged at the end of the first mounting plate 702 away from the first telescopic rod 701;

[0082] The first rotating rod 704 is symmetrically arranged on the outer wall of the first motor 703, and the outer wall of the first rotating rod 704 is rotatably connected to the outer wall of the first motor 703.

[0083] The cleaning mechanism 7 further includes:

[0084] The first housing 705 is installed at the bottom of the first rotating rod 704;

[0085] The first telescopic column 707 is symmetrically arranged on the top of the first housing 705, and a cleaning rod 706 is installed at the top of the first telescopic column 707;

[0086] The cleaning brush 708 is installed on the inner wall of the first housing 705, and the bottom of the cleaning brush 708 is in contact with the bottom of the inner wall of the box body 1.

[0087] When the abrasive passes through two screenings, the finest abrasive falls to the bottom of the box body 1, and the dust content in it is relatively high, which is more likely to adhere to the bottom of the inner wall of the box body 1. Moreover, due to the high dust content, its flow rate will slow down under the influence of humidity. At this time, the first telescopic rod 701 drives the first housing 705 on the first rotating rod 704 away from the discharge chute 5, so that the cleaning brush 708 can clean the bottom of the box body 1 and the cleaning rod 706 can clean the side of the box body 1, accelerating the discharge speed of the powdered abrasive and the fine abrasive. When the first telescopic rod 701 drives the first housing 705 to move inward, the first rotating rod 704 rotates, so that the cleaning rod 706 on the first housing 705 is away from the bottom of the inner wall of the box body 1. Then, when moving to the innermost side of the box body 1, the first rotating rod 704 vertically lowers the cleaning rod 706. The first rotating rod 704 and the second rotating rod 8041 can be freely telescoped to ensure that the bottom of the cleaning rod 706 is always in contact with the bottom of the inner wall of the box body 1 when it is lowered, maintaining the discharge speed, reducing the dust content in the box body 1, and cleaning the dust adhering to the inner wall of the box body 1.

[0088] Example 2, please refer to Figures 1 - 9 , the present invention provides a technical solution: on the basis of Example 1, the screening assembly 804 includes:

[0089] The second rotating rod 8041 is symmetrically arranged outside the first motor 703;

[0090] The second housing 8042 is installed at the bottom of the second rotating rod 8041, and openings 8043 are evenly arranged on the outer wall of the second housing 8042.

[0091] The screening assembly 804 further includes:

[0092] The rotating shaft 8044, both ends of the rotating shaft 8044 are rotatably connected to the inner wall of the second housing 8042, a baffle 8045 is arranged on the outer wall of the rotating shaft 8044, and square holes 8046 are evenly formed in the baffle 8045;

[0093] The scraping plate 8047, the scraping plate 8047 is arranged at the bottom of the baffle 8045, and the bottom of the scraping plate 8047 is in contact with the top of the sieve plate 9.

[0094] When the abrasive rolls down along the sieve plate 9, the second rotating rod 8041 approaches the feeding port 4 driven by the second telescopic rod 801. The second rotating rod 8041 rotates driven by the first motor 703, so that a certain distance is maintained between the bottom of the second housing 8042 and the top of the sieve plate 9. Subsequently, the second rotating rod 8041 rotates to the vertical state, and the second housing 8042 is placed on the top of the sieve plate 9. Then the second telescopic rod 801 slowly retracts, and the rotating shaft 8044 rotates reciprocally driven by the built-in drive in the second housing 8042, so that the scraping plate 8047 at the bottom scrapes reciprocally on the sieve plate 9. Larger abrasive particles are directly discharged through the square holes 8046, and the mixed abrasive particles are intercepted and ground by the scraping plate 8047, grinding and dispersing the mixed abrasive particles while slowing down the speed of the abrasive particles, and further sieving, avoiding agglomeration or directly discharging the precision abrasive particles with too fast moving speed of the abrasive particles, and improving the sieving precision.

[0095] The dust collection assembly 805 includes:

[0096] The collection box 8051, the collection boxes 8051 are symmetrically arranged on the outer wall of the second housing 8042, the outer wall of the collection box 8051 is in contact with the inner wall of the box body 1, and a lengthening plate 8052 is arranged at the opening 8043 end of the collection box 8051;

[0097] The second telescopic column 8053, the second telescopic column 8053 is installed on the inner wall of the collection box 8051;

[0098] The cover plate 8054, the cover plate 8054 is installed at the end of the second telescopic column 8053 far from the collection box 8051, and a brush plate 8055 is rotatably connected to the inner wall of the cover plate 8054.

[0099] The dust collection assembly 805 further includes:

[0100] The limiting block 8057, the limiting block 8057 is installed on the inner wall of the lengthening plate 8052, and the outer wall of the limiting block 8057 is slidably connected to the outer wall of the cover plate 8054;

[0101] The U-shaped rod 8056, the outer wall of the U-shaped rod 8056 is in contact with the outer wall of the limiting block 8057, and elastic rods 8058 are symmetrically arranged at the end of the U-shaped rod 8056 far from the limiting block 8057, and the end of the elastic rod 8058 far from the U-shaped rod 8056 is connected to the outer wall of the brush plate 8055.

[0102] The dust accumulation component moves along the inner wall of the box body 1 driven by the second telescopic column 8053. During the movement, the second telescopic column 8053 extends. Since the U-shaped rod 8056 on the limit block 8057 holds the elastic rod 8058 in place, the elastic rod 8058 is stretched and extended. During the extension of the second telescopic column 8053, the cover plate 8054 moves outward. Therefore, the brush plate 8055 remains in an outwardly open state under the elastic pull of the elastic rod 8058. When the second telescopic column 8053 retracts, the force exerted by the limit block 8057 and the U-shaped rod 8056 on the elastic rod 8058 decreases, causing the brush plate 8055 to contact the inner wall of the box body 1 and sweep the dust on the inner wall into the cover plate 8054. The bottom of the inner wall of the cover plate 8054 is inclined. Under the action of the vibrator 2, the concentrated dust finally enters the collection box 8051. In this way, the dust attached to both sides above the sieve plate 9 on the inner wall of the box body 1 is concentrated repeatedly, effectively reducing the residence time of dust on the inner wall of the box body 1, reducing the dust content in the box body 1, and separately recycling the dust, reducing the work of further screening and reducing the cleaning range of the staff.

[0103] The specific working process is as follows:

[0104] During operation, the feeding device conveys the abrasive through the feeding port 4 into the interior of the box body 1. The vibrator 2 is turned on to vibrate the box body 1 and screen the abrasive. There are two groups of sieve plates 9 with different precisions. The abrasive intercepted after passing through the sieve plate 9 is finally discharged through the discharge chute 5. When the abrasive enters the upper sieve plate 9, due to the inclined setting of the sieve plate 9 and the vibration of the vibrator 2, the abrasive can be spread on the sieve plate 9 for screening. At the same time, it also causes the accumulated abrasive to move too fast, resulting in the finer abrasive not being fully screened and following the large pieces of abrasive to be discharged. At this time, the second telescopic rod 801 drives the screening component 804 and the dust collection component 805 on the second motor 803 to approach the feeding port 4, buffer the speed of the abrasive to a certain extent, and recycle the dust attached to the inner wall. The second telescopic rod 801 reciprocates, slowly approaching the feeding port 4 and then quickly retracting, so that the buffer component is in the opposite direction to the flow direction of the abrasive, thus forming an opposite buffer to prevent the dust contained in the abrasive from adhering to the inner wall of the box body 1;

[0105] The air pipe 601 is externally connected to a blowing device. When the sieve plate 9 is working normally, the air outlet holes 605 of the air pipe 601 face downward. When the sieve plate 9 is blocked by abrasive fragments, the driving block 604 drives the conveyor belt 603 to rotate, causing the special-shaped block 602 clamped to the conveyor belt 603 to rotate, and then rotating a group of air pipes 601 simultaneously by a certain angle so that the air outlet holes 605 are aligned with the sieve plate 9. Then, the sieve plate 9 is subjected to an air flow impact through the externally connected blowing device to clean the fragments, avoiding shutdown. Finally, the smallest particles of the abrasive fall to the bottom of the box body 1;

[0106] When the abrasive passes through two sievings, the finest abrasive falls to the bottom of the box body 1. It contains a relatively high dust content and is more likely to adhere to the bottom of the inner wall of the box body 1. Moreover, due to the relatively high dust content, its flow rate will slow down under the influence of humidity. At this time, the first telescopic rod 701 drives the first cover 705 on the first rotating rod 704 to move away from the discharge chute 5, so that the cleaning brush 708 can clean the bottom of the box body 1 and the cleaning rod 706 can clean the side of the box body 1, accelerating the discharge speed of the powdery abrasive and the fine abrasive. When the first telescopic rod 701 drives the first cover 705 to move inwards, the first rotating rod 704 rotates, causing the cleaning rod 706 on the first cover 705 to move away from the bottom of the inner wall of the box body 1. Subsequently, when moving to the innermost side of the box body 1, the first rotating rod 704 vertically lowers the cleaning rod 706. The first rotating rod 704 and the second rotating rod 8041 can be freely telescoped to ensure that the bottom of the cleaning rod 706 always contacts the bottom of the inner wall of the box body 1 when lowered, maintaining the discharge speed, reducing the dust content in the box body 1, and cleaning the dust adhering to the inner wall of the box body 1.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
