Description

Technical Field

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

[0002] The crawler shot blasting machine loads the workpiece through a high-strength wear-resistant rubber crawler or a manganese steel crawler, and uses a high-speed rotating impeller to throw the projectiles onto the workpiece in the chamber to achieve the purpose of cleaning. During the use of the crawler shot blasting machine, the steel shots and impurities falling off the surface of the workpiece will fall into the steel shot collection box through the through holes on the crawler, waiting for the next use.

[0003] After searching, the Chinese patent publication number is CN219170598U. The disclosed crawler shot blasting cleaning machine includes a crawler shot blasting machine, a filter box and a fixed plate. A controller is fixedly connected to the outside of the crawler shot blasting machine. The filter box is slidably connected to the crawler shot blasting machine. The fixed plate is fixedly connected to the crawler shot blasting machine. The fixed plate is slidably connected to the filter box. During use, impurities dropped from steel shots and workpieces will fall into the filter box. After the work is completed, the first motor is controlled to rotate by the controller. The rotation of the first motor drives the semi-enclosed gear to rotate. The semi-enclosed gear drives the first connecting block to move through the rack. The first connecting block drives the filter box to reciprocate back and forth, and the impurities mixed in the steel shots can be filtered into the collection box. Therefore, impurities dropped from the workpiece mixed in the steel shots can be filtered during use, and the steel shots can be put into the crawler shot blasting machine for use again without damaging the crawler shot blasting machine.

[0004] In the above-mentioned prior art solution, the impurities contained in the steel shots are filtered into the collection box through the reciprocating motion of the filter box, so that the impurities that fall off the workpiece and are contained in the steel shots can be filtered out during use. However, in actual use, some lighter impurities will float in the air during the collision of the steel shots, and then be recycled together with the steel shots through the push of the slider, resulting in incomplete cleaning of the steel shots.

[0015] Compared with the prior art, the present invention has the following significant advantages:

[0016] First, the present invention collects and filters the steel shots through a screening mesh plate, and the impurities that fall with the steel shots fall into the interior of the collecting drawer through the gaps on the screening mesh plate, while the steel shots roll along the side walls of the screening mesh plate toward the discharge chute, and when the driving rod rotates downward, the pressure rod is driven to move downward, so that the pressure rod can squeeze the sealing cover plate to move downward, and the air at the bottom end of the sealing cover plate is output to the outside through the one-way valve and the blowing pipe on the isolation box, and the impurities floating in the gathering pipe are blown back onto the surface of the screening mesh plate, thereby preventing the impurities floating in the air from being used; the problem of insufficient thoroughness in the existing steel shot cleaning is solved.

[0017] Secondly, in the present invention, with the cooperation of the positioning plate, the positioning slot and the positioning slider, the movement of the pressure rod will drive the rotating rod to rotate around the rotating axis, so that the rotating rod is distributed in an inclined shape. With the cooperation of the return spring, the connecting rod and the connecting block, the two sealing cover plates will move in opposite directions respectively. The sealing cover plate moving downward will discharge the air at its bottom through the adjacent one-way valve, while the sealing cover plate moving upward will suck the external air into its bottom through the one-way valve on its top. When it moves downward, there is enough air at the bottom to be pressed out, so that the blowing pipe can always blow out airflow, avoiding airflow interruption, which makes it impossible to blow impurities floating inside the gathering pipe back onto the surface of the screening mesh.

[0018] Thirdly, in the present invention, when the conveyor plate moves with the conveyor belt, the conveyor plate will press against one end of the driving rod, so that the driving rod rotates around the connection between the mounting side plate and the supporting bottom plate, and the pulling bar will pull the linkage rod, the lifting bar and the screening mesh plate to move upward; when the conveyor plate and the driving rod are staggered, the elasticity of the positioning spring will pull the driving rod to return to its original state, and due to the elasticity of the positioning spring, the driving rod will shake continuously, and the screening mesh plate will shake repeatedly, so that the steel shots inside the screening mesh plate will collide with each other, and the impurities attached to the side walls of the steel shots will be shaken off, thereby reducing the possibility of impurities attached to the side walls of the steel shots.

[0019] Fourthly, the present invention, through the cooperation between the limit groove and the reinforcement strip, can make the rear end of the screening mesh plate only swing up and down, avoiding the gap between the screening mesh plate and the partition plate, which causes the steel shots to fall into the collection drawer. The limit groove and the shaking protrusions on the side walls of the reinforcement strip rub against each other, thereby further improving the shaking amplitude of the screening mesh plate.

By setting the lifting bar 47 in the shape of a "Λ" letter, there is no object on the top of the rear end of the screening mesh plate 42 to block the rolling of the steel shots, thereby facilitating the discharge of the steel shots. A linkage rod 48 is fixedly installed on the top wall of the lifting bar 47, and a shaking assembly is provided inside the outer box 1.

[0035] like Figure 2-Figure 8As shown, in order to facilitate the steel shot conveying plate 37 to take away the cleaned steel shots, a gathering tube 46 aligned with the discharge trough 45 is fixedly installed on the side wall of the partition plate 44, and the inner wall of the rear end of the gathering tube 46 is aligned with the inner wall of the partition box 38; the steel shots flowing outward through the discharge trough 45 are gathered by the partition plate 44 to ensure that the steel shots can fall into the interior of the partition box 38; an arc-shaped gathering plate 43 is fixedly installed at the bottom end of the inner wall of the partition box 38, and the gathering plate 43 is cocentric with the conveying roller 35 near the bottom; the steel shots flowing into the interior of the partition box 38 are collected by the gathering plate 43, and the gathering plate 43 is cocentric with the conveying roller 35 near the bottom, so that the conveying plate 37 can take away the steel shots inside the gathering plate 43, so that the steel shots can be fully utilized.

[0036] like Figure 2-Figure 8As shown, in order to prevent impurities from floating into the interior of the partition box 38 in the air, an exhaust assembly is provided inside the outer box 1, and the exhaust assembly includes an air storage box 61 fixedly mounted on the inner wall of the partition box 38, the front end of the air storage box 61 is fixedly connected to the rear end of the gathering pipe 46, a plurality of blowing pipes 62 are fixedly mounted on the bottom end of the front side wall of the air storage box 61, an isolation box 63 is fixedly mounted on the inner wall of the air storage box 61, an isolation plate is fixedly mounted on the inner wall of the isolation box 63, and sealing cover plates 64 are slidably mounted on the front and rear ends of the isolation plate on the isolation box 63, and the rear end of the top wall of the air storage box 61 slides through A pressure rod 65 is passed through, and a connecting groove 66 is provided at the rear end of the bottom wall of the driving rod 51. The top of the pressure rod 65 is rotatably installed inside the connecting groove 66. An air inlet groove 67 is provided at the top of the side wall of the air storage box 61. A one-way valve 68 is fixedly installed on the top wall of the two sealing cover plates 64. A one-way valve 68 is also fixedly installed on the front and rear ends of the bottom wall of the isolation box 63. The one-way valve 68 on the sealing cover plate 64 can only inlet air, and the one-way valve 68 on the isolation box 63 can only discharge air. A reset spring 69 is fixedly installed on the bottom wall of the sealing cover plate 64 near the pressure rod 65, and the bottom end of the reset spring 69 It is fixedly connected to the inner bottom wall of the isolation box 63; when the driving rod 51 rotates downward, the pressure rod 65 is driven to move downward, so that the pressure rod 65 can squeeze the sealing cover plate 64 to move downward, and the air at the bottom end of the sealing cover plate 64 is output outward through the one-way valve 68 and the blowing pipe 62 on the isolation box 63, and the impurities floating in the gathering pipe 46 are blown back to the surface of the screening mesh plate 42; the interior of the air storage box 61 is provided with a strengthening component, and the strengthening component includes a rotating rod 71 arranged inside the air storage box 61, and a rotating shaft 72 is fixedly installed on the side wall of the rotating rod 71, and the rotating shaft 72 The two ends are rotatably mounted on the inner wall of the air storage box 61, and two positioning plates 73 are fixedly mounted on the top wall of the rotating rod 71. The side wall surfaces close to the two positioning plates 73 are provided with positioning slide grooves 74. The bottom end of the pressure rod 65 is fixedly mounted with a positioning slider 75, and the positioning slider 75 is slidably mounted inside the positioning slide groove 74. The bottom wall surface of the rotating rod 71 away from the pressure rod 65 is fixedly mounted with two connecting blocks 77. The side wall surface close to the two connecting blocks 77 is rotatably mounted with a connecting rod 76, and the bottom end of the connecting rod 76 is fixedly mounted on the top wall of the adjacent sealing cover plate 64;With the cooperation of the positioning plate 73, the positioning slot 74 and the positioning slider 75, the movement of the pressure rod 65 will drive the rotating rod 71 to rotate around the rotating shaft 72, so that the rotating rod 71 is distributed in an inclined shape. With the cooperation of the return spring 69, the connecting rod 76 and the connecting block 77, the two sealing cover plates 64 will move in opposite directions respectively. The sealing cover plate 64 moving downward will discharge the air at its bottom through the adjacent one-way valve 68, while the sealing cover plate 64 moving upward will inhale the external air into its bottom through the one-way valve 68 on its top. When it moves downward, enough air at the bottom can be pressed out, so that the blowing pipe 62 can always blow out airflow, avoiding the interruption of airflow, which makes it impossible to blow the impurities floating inside the gathering pipe 46 back to the surface of the screening mesh plate 42.

[0037] The specific working method is as follows: the material to be processed is placed on the concave side wall of the placement crawler 24 by opening the discharge door 25, and then the discharge door 25 is closed. The guide roller 23 is driven to rotate by the output end of the driving motor 21, so that the placement crawler 24 drives the material to roll together. The placement crawler 24 is restricted by the guide plate 22, so that the side wall of the placement crawler 24 is concave, which is convenient for accommodating the material. The steel shot is sprayed out by the sandblasting equipment 31 to clean the surface of the material. The sprayed steel shot falls on the surface of the screening mesh plate 42. When the conveying plate 37 moves with the conveying belt 36, the conveying plate 37 will resist the driving The end of the rod 51 makes the driving rod 51 rotate around the connection between the mounting side plate 52 and the supporting bottom plate 53, and the pulling bar 55 pulls the linkage rod 48, the lifting bar 47 and the screening mesh plate 42 to move upward. When the feeding plate 37 and the driving rod 51 are staggered, the elasticity of the positioning spring 54 will pull the driving rod 51 to restore the original state, and due to the elasticity of the positioning spring 54, the driving rod 51 will shake continuously, and the screening mesh plate 42 will shake repeatedly. The limiting groove 57 and the shaking protrusion 58 on the side wall of the reinforcement bar 49 rub against each other, further increasing the shaking amplitude of the screening mesh plate 42, so that the steel shots inside the screening mesh plate 42 collide with each other, and the steel shots attached to the side The impurities on the wall are shaken off, and the steel shot rolls along the side wall of the screening mesh plate 42 to the discharge chute 45, and then enters the interior of the gathering pipe 46. When the driving rod 51 rotates, it will drive the pressure rod 65 to move up and down together. Under the cooperation of the positioning plate 73, the positioning slide groove 74 and the positioning slider 75, the movement of the pressure rod 65 will drive the rotating rod 71 to rotate around the rotating shaft 72, so that the rotating rod 71 is distributed in an inclined shape. Under the cooperation of the return spring 69, the connecting rod 76 and the connecting block 77, the two sealing cover plates 64 will move in opposite directions respectively. The sealing cover plate 64 moving downward will discharge the air at its bottom through the adjacent one-way valve 68, while the sealing cover plate moving upward will discharge the air at its bottom to the outside through the adjacent one-way valve 68. The cover plate 64 will draw outside air into its bottom through the one-way valve 68 on its top. When it moves downward, there is enough air at the bottom to be pressed out, and the air inside the isolation box 63 is output to the outside through the air blowing pipe 62, blowing the impurities floating inside the gathering pipe 46 back to the surface of the screening mesh plate 42, and guiding the steel shots to fall into the interior of the separation box 38 through the gathering pipe 46. The feed roller 35 is driven to rotate through the output end of the feed motor 34, so that the feed belt 36 sleeved on the side wall of the feed roller 35 rotates, and the feed plate 37 digs out the steel shots inside the separation box 38, and then flows back to the interior of the sandblasting equipment 31 through the sand inlet pipe 32, so that the steel shots can be recycled.
