A crawler-type shot blasting machine loading and unloading device

Abstract

This invention provides a loading and unloading device for a tracked shot blasting machine. The device includes trolleys, a material storage bin, guide rods, guide wheels, a lifting component, and a guide plate. The device features two trolleys on the side of the tracked shot blasting machine with the feed inlet. These trolleys can alternately move below the feed inlet. A material storage bin is mounted on each trolley, and a lifting component is installed on the top of the machine. When material needs to be discharged, the lifting component lifts the material storage bin on the trolley, moves it upward, and rotates it. When material needs to be collected, the guide plate on the material storage bin is unfolded, driving the internal track of the shot blasting machine to reverse, causing the product to fall out onto the guide plate and then into the material storage bin. This completes the collection operation. Simultaneously, the device can repeatedly transport products from the material storage bin into the shot blasting machine, facilitating operation and the rework of defective products.

Description

Technical Field

[0001] This invention belongs to the field of shot blasting equipment technology, specifically relating to a loading and unloading device for a tracked shot blasting machine. Background Technology

[0002] Tracked shot blasting machines use high-strength, wear-resistant rubber or manganese steel tracks to load workpieces. They utilize a high-speed rotating impeller to propel shot onto the workpiece inside the chamber, achieving a cleaning effect. Tracked shot blasting machines are typically used for processing small, loose parts. To improve feeding efficiency, they are generally equipped with a feeding device and a receiving device for adding materials into the machine. However, currently, these feeding and receiving devices are relatively simple in function, and most receiving devices use conveyor belts. When the inspected parts fail to meet standards, they need to be reassembled and transported back to the feeding device for rework. This complicates the rework process and makes on-site operation inconvenient. Summary of the Invention

[0003] This invention provides a loading and unloading device for a tracked shot blasting machine, which aims to solve the problem that the loading and unloading devices for tracked shot blasting machines in the prior art have limited functions and are inconvenient for product repair.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a feeding and unloading device for a tracked shot blasting machine, comprising:

[0005] There are two pulleys, which are spaced apart and connected end to end. The two pulleys can move alternately to the feeding port of the tracked shot blasting machine.

[0006] The material storage bin is freely mounted on the trolley.

[0007] A guide rod is mounted vertically on the trolley, and the top end of the guide rod is an arc-shaped part that bends toward the tracked shot blasting machine;

[0008] A guide wheel is rotatably mounted on the material hopper. The guide rod has a U-shaped groove inside for accommodating the guide wheel. The guide wheel is rotatably mounted inside the U-shaped groove. The end of the arc-shaped part has a limiting plate for preventing the guide wheel from sliding out of the U-shaped groove.

[0009] A lifting device, installed on top of a tracked shot blasting machine, is used to lift and tilt the material hopper upwards when the hopper moves to the feed port of the shot blasting machine.

[0010] A guide plate is hinged to the opening of the material container to guide the product into the material container. A support member is also provided between the guide plate and the material container to support the guide plate.

[0011] In one possible implementation, a connecting unit is further provided between the lifting component and the hopper, the connecting unit comprising:

[0012] An arc-shaped frame is installed on a crawler shot blasting machine. The arc-shaped frame is provided with two spaced arc-shaped channels, which are arranged from bottom to top towards the crawler shot blasting machine.

[0013] A connecting rod is slidably disposed at both ends inside the arc-shaped channel, and the lifting component is connected to the connecting rod to drive the connecting rod to move inside the arc-shaped channel;

[0014] The hook is swung on the material hopper. When the material hopper moves below the connecting rod, the hook body can be attached to the connecting rod.

[0015] A swing assembly is disposed between the arc-shaped frame and the hook for driving the hook to swing.

[0016] In one possible implementation, the hook is hinged at the middle to the hopper, and a gravity block is installed at the end of the hook away from the hook body.

[0017] In one possible implementation, the oscillating component includes:

[0018] The pressing wheel is rotatably mounted at the bottom of the arc-shaped frame;

[0019] A movable rod is slidably mounted on the material hopper in a vertical direction. A gear is rotatably mounted in the middle of the movable rod. The middle part of the hook is fixedly mounted on the gear. Both ends of the movable rod are provided with chamfers to facilitate the rotation of the pressing wheel to the top of the movable rod.

[0020] A rack is installed vertically on the hopper and meshes with the gear. When the moving rod moves downward, the gear drives the hook to swing outward.

[0021] In one possible implementation, when the movable rod disengages from the pressing wheel, the movable rod moves upward and the gear disengages from the rack.

[0022] In one possible implementation, the bottom of the trolley is fitted with a guide rail for guiding the movement of the trolley, the height of the two ends of the guide rail being lower than the height of the middle of the guide rail.

[0023] In one possible implementation, the loading and unloading device of the tracked shot blasting machine further includes a drive assembly for driving the trolley to move, the drive assembly comprising:

[0024] A chain, the two ends of which are respectively fixedly connected to the two pulleys;

[0025] There are two guide sprockets, which are respectively rotatably disposed at both ends of the guide rail and are both meshed with the chain.

[0026] A drive sprocket is meshed with the chain and is used to drive the chain to move.

[0027] In one possible implementation, a mounting bracket is provided on the outer side of the guide rail, and a guide component for preventing the trolley from tilting downwards when it moves is also provided between the mounting bracket and the trolley.

[0028] In one possible implementation, the guiding component includes:

[0029] There are two support wheels, both of which are rotatably mounted on the trolley and are spaced apart along the height direction.

[0030] There are two guide rails, both of which are mounted on the mounting frame. The two guide rails are spaced apart in the vertical direction, and the distance between the two guide rails in the direction of movement of the trolley is the same as the distance between the two support wheels in the direction of movement of the trolley. The support wheels are rotatably disposed inside the guide rails.

[0031] In one possible implementation, the fixed end of the support member is hinged to the hopper, and the driving end of the support member is hinged to the guide plate.

[0032] The solution described in this application, compared with the prior art, involves installing two trolleys on the side of the crawler shot blasting machine with the feed inlet. These two trolleys are connected end-to-end and can move alternately to below the feed inlet. A material storage bin is installed on each trolley, allowing products to be placed inside. When the trolley reaches the feed inlet, a lifting device can be used to lift the bin upwards. When the guide wheels on the bin move to the limiting plate at the end of the arc-shaped section, the lifting device continues to lift the bin, causing it to flip and allowing the product inside to fall into the crawler shot blasting machine. After processing is complete, the bin can be lowered back onto the trolley, allowing the guide plate to unfold below the crawler at the feed inlet. Then, the crawler inside the shot blasting machine is reversed, allowing the product to move with the guide plate into the bin. Simultaneously, the trolley can be switched to process the next batch of products. If a product still fails shot blasting, it can remain in the storage bin until the shot blasting machine finishes processing. Then, the trolley position is switched again, and the unqualified product is re-transported back into the machine for rework. Meanwhile, the product on the other trolley can be inspected, unloaded, and reloaded. The operation is simple. Products on both trolleys can be unloaded and replaced individually, and the storage bins on both trolleys can simultaneously handle loading and unloading, facilitating on-site use and operation, and enabling the rework of defective products.

[0040] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0041] Please refer to the following: Figures 1 to 5 The loading and unloading device for a tracked shot blasting machine provided by the present invention will now be described. The loading and unloading device includes a trolley 2, a material container 3, a guide rod 4, a guide wheel 31, a lifting component 5, and a guide plate 32. Two trolleys 2 are arranged alternately and connected end-to-end, allowing them to move alternately to the feeding port of the tracked shot blasting machine 1. The material container 3 is freely mounted on the trolley 2. The guide rod 4 is mounted vertically on the trolley 2, and its top end is an arc-shaped portion bent towards the tracked shot blasting machine 1. The guide wheel 31 is rotatably mounted on the material container 3, and the guide rod 4 has a U-shaped groove inside for accommodating the guide wheel 31, which rolls within the U-shaped groove. Inside the U-shaped groove, the end of the arc-shaped part is provided with a limiting plate for limiting the guide wheel 31 to slide out of the U-shaped groove; the lifting component 5 is installed on the top of the crawler shot blasting machine 1, and is used to lift the material container 3 to move upward and flip when the material container 3 moves to the feeding port of the shot blasting machine 1; the guide plate 32 is hinged to the opening of the material container 3, and is used to guide the product to fall into the material container 3. A support component 321 is also provided between the guide plate 32 and the material container 3 to support the guide plate 32.

[0042] Compared with the prior art, the feeding and unloading device for the tracked shot blasting machine provided in this embodiment features two trolleys 2 connected end-to-end on the side of the tracked shot blasting machine 1 with the feed inlet. These trolleys 2 can move alternately to the area below the feed inlet. A material storage bin 3 is installed on each trolley 2, allowing products to be placed inside. When the trolley 2 moves to the feed inlet, a lifting device 5 can be used to lift the material storage bin 3 upwards. When the guide wheel 31 on the material storage bin 3 moves to the limiting plate at the end of the arc-shaped section, the lifting device 5 continues to lift the material storage bin 3, causing it to flip and allowing the products inside to fall into the tracked shot blasting machine 1. After processing is complete, the material storage bin 3 can be lowered back onto the trolley 2, allowing the guide plate 32 to unfold below the track at the feed inlet. Then, the track inside the tracked shot blasting machine 1 is reversed, allowing the products to move with the guide plate 32 into the material storage bin 3. Simultaneously, trolley 2 is switched to process the next batch of products. If a product still fails to meet the requirements after shot blasting, it can be placed back into the material storage bin 3. After the products in shot blasting machine 1 have finished processing, trolley 2 is switched back to its original position, and the unqualified products are transported back into shot blasting machine 1 for rework. Meanwhile, the products on the other trolley 2 can be inspected, unloaded, and reloaded. The operation is simple. Products on both trolleys 2 can be unloaded and replaced individually. At the same time, the material storage bins 3 on both trolleys 2 can simultaneously meet the loading and unloading operations, facilitating on-site use and operation, and making it easy to rework defective products.

[0043] Specifically, in this embodiment, two fixed rods are arranged at intervals on the material storage bin 3 along the moving direction of the trolley 2. The fixed rods are arranged vertically, and two guide wheels 31 are arranged vertically on the fixed rods. A limiting groove is provided at the bottom of the fixed rod to prevent the guide wheels 31 from sliding out. When the top guide wheel 31 slides to the arc-shaped part, the bottom guide wheel 31 slides out from the limiting groove. Thus, when the lifting device 5 continues to lift the material storage bin 3, the bottom of the material storage bin 3 can be gradually flipped upward to pour the product into the shot blasting machine 1.

[0044] Specifically, in this embodiment, the guide wheel 31 is located on the side of the material storage bin 3 closer to the shot blasting machine 1, and the connection position between the lifting component 5 and the material storage bin 3 is located on the side of the material storage bin 3 away from the shot blasting machine 1.

[0045] In some embodiments, the lifting component 5 can be adopted as follows: Figure 2 , Figure 3 and Figure 4 The structure shown. See also... Figure 2 , Figure 3 and Figure 4A connecting unit 6 is also provided between the lifting component 5 and the material storage bin 3. The connecting unit 6 includes an arc-shaped frame 61, a connecting rod 62, a hook 33, and a swing assembly 34. The arc-shaped frame 61 is installed on the crawler shot blasting machine 1. The arc-shaped frame 61 has two spaced arc-shaped channels, which gradually move towards the crawler shot blasting machine 1 from bottom to top. The two ends of the connecting rod 62 are slidably disposed inside the arc-shaped channels. The lifting component 5 is connected to the connecting rod 62 to drive the connecting rod 62 to move inside the arc-shaped channels. The hook 33 is swayingly disposed on the material storage bin 3. When the material storage bin 3 moves below the connecting rod 62, the hook body on the hook 33 can be hooked onto the connecting rod 62. The swing assembly 34 is disposed between the arc-shaped frame 61 and the hook 33 to drive the hook 33 to swing. A connecting frame is provided on the top of the crawler shot blasting machine 1, extending towards the side of the trolley 2. The lifting component 5 is installed on the connecting frame and is slidably disposed on the connecting frame along the extension direction of the connecting frame. The arc-shaped frame 61 is fixedly installed on the connecting frame and located below the connecting frame. The arc-shaped frame 61 includes two spaced arc-shaped channels, which are arranged opposite each other. A connecting rod 62 is installed inside the arc-shaped channels, and rollers that are rotatably mounted at both ends of the connecting rod 62 are rolled inside the arc-shaped channels. During the process of the trolley 2 moving to the feed port of the shot blasting machine 1, the hook 33 is first pushed by the swing assembly 34 to swing and avoid the arc-shaped frame 61. When the trolley 2 moves to the feed port, the swing assembly 34 drives the hook 33 to swing in the opposite direction, so that the hook 33 can hook onto the connecting rod 62. This realizes the connection between the connecting rod 62 and the material container 3. When the lifting component 5 moves the connecting rod 62 upward, the guide of the arc-shaped frame 61 can assist the tilting of the material container 3, ensuring the stability of the material container 3 during rising and tilting. After unloading, the swing assembly 34 can push the hook 33 to swing, so that the hook 33 disengages from the connecting rod 62 and the trolley 2 can be moved out from under the arc-shaped frame 61.

[0046] In some embodiments, the hook 33 described above may be as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4 The hook 33 is hinged in the middle to the material container 3, and a gravity block 331 is installed at the end of the hook 33 away from the hook body. With the gravity block 331 and the hook body at both ends of the hook 33, the gravity block 331 automatically keeps the hook 33 in a vertical position. Simultaneously, when the connecting rod 62 moves within the arc-shaped channel on the arc-shaped frame 61, the hook 33 also remains in a vertical position. This prevents the hook 33 from detaching after flipping, improving stability during use.

[0047] In some embodiments, the aforementioned swing component 34 may employ, for example... Figure 4 The structure shown. See also Figure 4The swing assembly 34 includes a pressing wheel 341, a moving rod 342, and a gear 344. The pressing wheel 341 is rotatably mounted at the bottom of the arc-shaped frame 61; the moving rod 342 is slidably mounted on the material storage bin 3 in the vertical direction, and a gear 343 is rotatably mounted in the middle of the moving rod 342. The hook 33 is fixedly mounted on the gear 343 in the middle, and both ends of the moving rod 342 are chamfered to facilitate the rotation of the pressing wheel 341 to the top of the moving rod 342; the gear 344 is mounted vertically on the material storage bin 3 and meshes with the gear 343. When the moving rod 342 moves downward, the gear 343 drives the hook 33 to swing outward. The pressing wheel 341 is rotatably mounted at the bottom of the arc-shaped frame 61. When the trolley moves to the bottom of the arc-shaped frame 61, the pressing wheel 341 presses the moving rod 342 downward through the guide of the chamfer at the end of the moving rod 342. When the moving rod 342 moves downward, the rack 344 drives the gear 343 to rotate, thereby realizing the swing of the swing arm. This avoids interference between the swing arm and the arc frame 61 during the movement. When the trolley 2 moves to the point where the pressing wheel 341 disengages from the moving rod 342, the gravity block 331 on the hook 33 comes into play, driving the hook 33 to swing vertically. This causes the hook on the hook 33 to automatically rotate to the connecting rod 62. This achieves automatic connection and automatic release switching between the hook 33 and the connecting rod 62 during the movement of the trolley 2.

[0048] In some embodiments, the gear 343 described above may be as follows: Figure 4 The structure shown. See also Figure 4 When the moving rod 342 disengages from the pressing wheel 341, the moving rod 342 moves upward and the gear 343 disengages from the rack 344. A U-shaped guide with an upward-facing opening is provided on the side of the material container 3 away from the shot blasting machine 1, with the length of the U-shaped guide aligned with the moving direction of the trolley 2. The moving rod 342 slides vertically inside the U-shaped guide. A rack 344 is also installed on the inner wall of the U-shaped guide. A gear 343 is rotatably mounted on the moving rod 342, meshing with the rack 344. When the pressing wheel 341 moves to the top of the moving rod 342, the pressing wheel 341 presses the moving rod 342, causing the gear 343 to move downward and thus rotate. When the pressing wheel 341 disengages from the moving rod 342, the gravity block 331, under its own weight, causes the moving rod 342 to swing, thereby causing the gear 343 to move the moving rod 342 upward until the gear 343 disengages from the rack 344. When the connecting rod 62 moves on the arc frame 61, it can keep the hook 33 in a vertical position at all times.

[0049] Preferably, in this embodiment, an elastic element, which is a spring, is provided between the moving rod 342 and the material container 3 to drive the moving rod 342 to move upward. The elastic element allows the gear 343 to effectively disengage from the rack 344.

[0050] In some embodiments, the aforementioned trolley 2 may employ, as follows: Figure 5 The structure shown. See also Figure 5 The bottom of the trolley 2 is equipped with guide rails 7 for guiding its movement. The height of the two ends of the guide rails 7 is lower than the height of the middle part of the guide rails 7. The guide rails 7 are installed on the ground, with the height of the two ends lower than the height of the middle part of the guide rails 7. When the trolley 2 moves to the two ends, it can move the material hopper 3 downwards. Lowering the height of the material hopper 3 allows for the use of external lifting equipment to assist in tilting during unloading, and facilitates the collection of products.

[0051] In some embodiments, the driving component 8 described above may employ, for example... Figure 5 The structure shown. See also Figure 5 The loading and unloading device of the tracked shot blasting machine also includes a drive assembly 8 for driving the movement of the trolleys 2. The drive assembly 8 includes a chain 83, guide sprockets 82, and drive sprockets 81. Both ends of the chain 83 are fixedly connected to the two trolleys 2. There are two guide sprockets 82, which are rotatably mounted at both ends of the guide rail 7 and mesh with the chain 83. The drive sprockets 81 mesh with the chain 83 and are used to drive the chain 83 to move. Both ends of the chain 83 are wrapped around the outside of the guide sprockets 82 and connected to the trolleys 2. The drive sprocket 81 is meshed in the middle of the chain 83. The drive sprocket 81 is driven to rotate by a reversible motor, thereby driving the chain 83 to move. When the drive sprocket 81 moves in two different directions, the positions of the two trolleys 2 can be switched. The structure is simple and easy to operate.

[0052] In some embodiments, the guide rail 7 may be as follows: Figure 5 Structure. See also Figure 5 A mounting bracket is provided on the outer side of the guide rail 7, and a guide component 9 is provided between the mounting bracket and the trolley 2 to prevent the trolley 2 from tilting downwards when moving. The guide component 9 ensures that the opening of the trolley 2 remains upwards when descending or ascending, preventing products located inside the storage bin 3 from sliding out after tilting.

[0053] In some embodiments, the guide component 9 described above may employ, for example... Figure 5 The structure shown. See also Figure 5The guide assembly 9 includes support wheels 91 and guide rails 92. There are two support wheels 91, both rotatably mounted on the trolley 2, and spaced apart along the height direction. There are also two guide rails 92, both mounted on a mounting frame, spaced apart vertically, with the distance between them along the movement direction of the trolley 2 being the same as the distance between the support wheels 91 along the movement direction of the trolley 2. The support wheels 91 are rolled within the guide rails 92. Support wheels 91 are rotatably mounted on the side wall of the trolley 2, and are rolled within the guide rails 92. The two guide rails 92 have the same shape, and their ends gradually slope downwards. This allows them to guide the trolley 2 downwards along with the guide rails 7, ensuring that the opening of the hopper 3 is always facing upwards.

[0054] Specifically, in this embodiment, the guide rail 92 has a U-shaped cross-section. The guide rail 92 includes two wing plates spaced apart vertically. The support wheels 91 are confined within the guide rail 92 by the wing plates. Two support beams are spaced apart on the trolley 2 along its direction of movement. The two guide rails 92 are staggered relative to each other along the direction of movement of the trolley 2. This ensures that the two support wheels 91 on the trolley 2 change height synchronously.

[0055] In some embodiments, the support member 321 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The fixed end of the support member 321 is hinged to the material storage bin 3, and the driving end of the support member 321 is hinged to the guide plate 32. The support member 321 is a pneumatic cylinder or a hydraulic cylinder, and there are at least two support members 321, which are spaced apart along the length of the guide plate 32. This provides effective support for the guide plate 32.

[0056] Preferably, in this embodiment, a ramp is provided on the side of the material container 3 near the shot blasting machine 1 to facilitate the product sliding out. A limiting plate is installed on the ramp to limit the position of the ramp when the guide plate 32 is flush with it. At the same time, the flushness between the ramp and the guide plate 32 helps the product fall into the shot blasting machine 1.

[0057] Specifically, in this embodiment, the support member 321 is a cylinder or hydraulic cylinder, which can retract the guide plate 32 when the trolley 2 moves, thus preventing the guide plate 32 from interfering with the shot blasting machine 1. When the trolley 2 moves to below the feed inlet of the shot blasting machine 1, the guide plate 32 can be opened by the support member 321, thereby guiding the product into the material storage bin 3.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
