Description

Technical Field

[0001] The invention relates to the technical field of shot blasting machines, in particular to a crawler cleaning device of a shot blasting machine. Background Art

[0002] During the process of polishing workpieces, the crawler belt rotating inside the crawler shot blasting machine is prone to adhere to some dust or residues, which may clog the holes on the surface of the crawler belt, affecting the normal use of the crawler belt and the service life of the crawler belt. The existing cleaning devices all use air blowing to clean them, but when some stubborn residues are stuck in the holes, the wind force generated by the fan cannot blow them off, resulting in incomplete cleaning.

[0003] After searching the Chinese patent with publication number CN218082226U, a shot blasting machine track cleaning device is disclosed. A cleaning component is set up, and the component drives the cleaning brush to rotate through motor 1, and then drives the cleaning brush to contact the track surface through an electric push rod, thereby achieving cleaning of the track. By setting a center rod, a buffer spring and a limit block, a buffering effect can be played when adjusting the contact force between the cleaning brush and the track. By setting a cleaning brush displacement adjustment component, the component drives the screw rod to rotate through motor 2, thereby driving the cleaning brush to adjust the lateral displacement, so that the cleaning brush can clean tracks of different widths.

[0004] Based on the above search and the prior art, it is found that when cleaning the track of a shot blasting machine, a brush is often used to clean it directly. It is difficult for the brush to completely fit the size of the track. The track remains stationary during cleaning, and the cleaning speed of the brush is slow. The cleaning is not comprehensive when the track is moving, and the cleaning effect of using a brush alone is poor. Impurities such as oil on the track will also adhere to the surface of the brush, affecting the subsequent cleaning of the track, thereby reducing the cleaning efficiency of the shot blasting machine track.

Through the cooperation of a main transmission wheel and two auxiliary transmission wheels, the transmission belt and the brush can be arranged in a triangle.

[0016] Secondly, the present invention is provided with a nozzle, a transmission belt and a brush. The cleaning liquid sprayed by the nozzle can not only clean the oil stains and impurities on the track, but also cooperate with the brush to increase the cleaning effect. A part of the cleaning liquid is also sprayed on the brush to wet the impurities on the brush, making it easier for the impurities to fall off, and cleaning the brush itself, thereby ensuring the cleaning effect of the brush.

[0017] Thirdly, the present invention is provided with a rectangular frame and a cleaning plate, and cleaning comb teeth are arranged on the cleaning plate. When the transmission belt drives the brush to rotate clockwise, it contacts the cleaning plate on the right side of the rectangular frame. The cleaning comb teeth on the cleaning plate clean and scrape off the sewage and impurities adhered to the brush, so that they slide directly along the inclined cleaning plate and fall on both sides of the crawler track. Conversely, when the transmission belt rotates counterclockwise, it will also be cleaned by the cleaning plate on the other side, which can further ensure the cleaning effect of the brush and can also effectively prevent sewage and impurities from returning to the crawler track and affecting the cleaning of the crawler track.

[0031] Furthermore, the nozzles 14 are arranged at an angle and are distributed in a linear array. A controller 25 is installed on the top outer wall of the mounting frame 8. The controller 25 is electrically connected to the solenoid valve 15, the solenoid valve 2, and the rotary encoder 29. A slide rail is provided on the inner wall of the mounting frame 8. The sliding frame 21 is slidably connected to the inner wall of the slide rail. A pump body is installed on the end of the water inlet pipe 19 away from the mounting frame 8, and the rectangular frame 11 is slidably connected to the inner wall of the mounting frame 8.

[0032] Furthermore, cleaning plates 30 are fixedly connected to the inner walls on both sides of the rectangular frame 11, and the cleaning plates 30 are arranged at an angle. Cleaning comb teeth 31 are arranged on the outer wall on one side of the cleaning plate 30, and the cleaning comb teeth 31 are adapted to the size of the brush 10. The outer walls on both sides of the top of the mounting frame 8 are fixedly connected to the limiting rods 18, and the outer walls on both sides of the bottom end of the main bracket 1 are provided with limiting holes, and the limiting rods 18 are slidably connected to the inner walls of the limiting holes. When the mounting frame 8 moves, it is slidably connected to the main bracket 1 through the limiting rods 18 to improve the stability of the structure.

[0033] Furthermore, the outer walls on both sides of the main bracket 1 are slidably connected with support frames 6, and the support frames 6 are arranged in an L shape. A connecting groove is opened on the outer wall of one side of the top of the support frame 6, and a sleeve 4 is rotatably arranged on the inner wall of the connecting groove. The inner wall of the sleeve 4 is threadedly connected with a bidirectional screw 3, and the bidirectional screw 3 is adapted to the height of the hydraulic rod 2. An anti-skid sleeve is arranged on the middle outer wall of the bidirectional screw 3, and an anti-skid pad 5 is bonded to the outer wall of the other side of the support frame 6. The rectangular frame 11 is adapted to the position of the shunt pipe 13, the mounting frame 8 is adapted to the size of the main bracket 1, the transmission belt 26 is arranged in a triangle, the nozzle 14 is adapted to the position of the brush 10, and the anti-skid pad 5 arranged on one side of the support frame 6 increases the friction between the support frame 6 and the shot blasting cleaning machine, thereby further improving the structural stability.

[0034] Working principle: when it is necessary to clean the crawler track of the shot blasting machine, the sleeves 4 on both sides of the two-way screw 3 are twisted to make the support frame 6 slide against the position above the crawler track of the shot blasting machine, and the hydraulic rod 2 is started to make the brush 10 on the transmission belt 26 contact the outer wall of the crawler track, and the motor 2 12 is controlled to work, driving the main transmission wheel 27 to rotate, thereby cooperating with the auxiliary transmission wheel 28 on the sliding frame 21 to drive the transmission belt 26 and the brush 10 to move. The two horizontally arranged auxiliary transmission wheels 28 make the bottom brush 10 horizontally contact the outer wall of the entire crawler top, and directly clean the impurities on the entire crawler surface when moving. When it is necessary to adjust the length of the horizontal brush 10 at the bottom of the transmission belt 26 according to the width of the crawler track, start the motor 1 9 to rotate the two-way screw 20 to drive the two sliding frames 21 to separate or move together. When the two-way screw 20 rotates, it also drives the one-way screw 24 to rotate through the meshing bevel gear 1 22 and bevel gear 2 23, thereby driving the rectangular frame 11 to descend or rise, thereby controlling the main transmission The height of the wheel 27 keeps the transmission belt 26 in a taut state to prevent it from loosening and being unable to continue to transmit. While the brush 10 cleans the crawler track, the pump body also transports the cleaning liquid to the water inlet pipe 19. When the main transmission wheel 27 drives the transmission belt 26 to rotate clockwise under the action of the motor 2 12, the rotary encoder 29 transmits an electrical signal to the controller 25, so that the controller 25 controls the solenoid valve 15 to open and the solenoid valve 2 16 to close, and the cleaning liquid is sprayed out through the shunt pipe 13 and the nozzle 14 at the bottom of the branch pipe 1 7 to clean the crawler track in the direction opposite to the brush 10, and the cleaning effect is further increased in cooperation with the brush 10. After that, when the motor 2 12 controls the transmission belt 26 to rotate counterclockwise, the controller 25 receives the signal and controls the solenoid valve 15 to close and the solenoid valve 2 16 to open, so that the shunt pipe 13 and the nozzle 14 at the bottom of the branch pipe 2 17 spray the cleaning liquid to cooperate with the brush 10 for cleaning, and the sprayed cleaning liquid always corresponds to the movement direction of the brush 10, thereby maximizing the cleaning effect.

[0035] The hydraulic rod 2 controls the lifting and lowering of the mounting frame 8, and can adjust the height and the contact force between the brush 10 and the crawler track to increase the scope of application. When the mounting frame 8 moves, it is slidably connected to the main bracket 1 through the limit rod 18 to improve the stability of the structure. Cleaning plates 30 are inclinedly arranged on the inner walls of both sides of the top of the rectangular frame 11, and cleaning comb teeth 31 are arranged on the cleaning plates 30. When the transmission belt 26 drives the brush 10 to rotate clockwise, it contacts the cleaning plate 30 on the right side of the rectangular frame 11. The cleaning comb teeth 31 on the cleaning plate 30 clean and scrape off the sewage and impurities adhered to the brush 10, so that they slide directly onto both sides of the crawler track along the inclined cleaning plate 30. Conversely, when the transmission belt 26 rotates counterclockwise, it will also be cleaned by the cleaning plate 30 on the other side, which not only ensures the cleaning effect of the brush 10, but also prevents sewage and impurities from returning to the crawler track to affect the cleaning of the crawler track.

[0036] The main bracket 1 is fixed to the inner wall of the shot blasting machine by the support frames 6 on both sides. The corresponding support frame 6 can be pushed to move by twisting the sleeve 4. The anti-skid pad 5 set on one side of the support frame 6 increases the friction between the support frame 6 and the shot blasting machine, further improving the structural stability.
