Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a leak-proof device for the feed inlet of a shot blasting machine. Background Technology

[0002] In the foundry industry, hook-type shot blasting machines are commonly used for cleaning and strengthening the surface of castings. Their working principle involves using a hook to lift the casting into the shot blasting machine, where steel shot is sprayed onto the surface to achieve a smooth finish. To facilitate the hook's entry into the machine, existing hook-type shot blasting machines typically have a clearance slot at the top, allowing the hook to move up and down through this slot for lifting and unloading the casting.

[0003] However, the existing design of the clearance groove in hook-type shot blasting machines has significant flaws: to ensure smooth passage of the hook, the width of the clearance groove is usually larger than the hook diameter, causing the high-speed steel shot ejected inside the machine to easily splash out of the groove opening. Although existing technologies use soft brushes inside the clearance groove to block the steel shot, due to the high speed and strong impact of the shot, a large amount of steel shot still penetrates the brushes and splashes outside the equipment. Furthermore, the soft brushes are prone to wear after prolonged impact from the steel shot, significantly reducing their leak-proof effect. This not only wastes steel shot and increases production costs, but the splashed steel shot also poses a safety threat to operators, presenting a significant safety hazard.

[0004] Therefore, there is an urgent need for a shot blasting machine outlet leak prevention device that can effectively prevent steel shot from splashing out of the shot blasting machine outlet, reduce steel shot waste, improve equipment safety, and has long-lasting leak prevention performance, in order to solve the technical problems of poor sealing effect of the avoidance groove and easy wear of components in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof device for the feed inlet of a shot blasting machine, so as to solve the problems existing in the current hook-type shot blasting machine mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof device for the feed inlet of a shot blasting machine, comprising:

[0007] A hook-type shot blasting machine, wherein a crane hook is movably mounted on the hook-type shot blasting machine;

[0008] An obstacle clearance groove is formed inside the top of the hook-type shot blasting machine. A guide groove plate is fixedly connected to the top of the obstacle clearance groove, and the inner side of the guide groove plate is hollow.

[0009] A servo motor is installed on the top of the hook-type shot blasting machine. The motor shaft of the servo motor is fixedly connected to a material-stopping turntable, and a mating groove is formed through the material-stopping turntable.

[0010] Preferably, the material-blocking turntable is disposed above the guide groove plate, and the material-blocking turntable is adapted to cover the area above the guide groove plate.

[0011] Preferably, the bottom of the material stop turntable is provided with a buffer rubber layer.

[0012] Preferably, the width of the mating groove is adapted to the diameter of the middle part of the crane hook, and the projection of the mating groove and the clearance groove in the vertical direction coincides in a quadrilateral shape.

[0013] Preferably, a circumferential protective plate is fixedly connected to the bottom of the material blocking turntable. The circumferential protective plate is arranged along the edge extension direction of the material blocking turntable, and a hook inlet is provided on the circumferential protective plate. The position of the hook inlet corresponds to the opening of the mating groove.

[0014] Preferably, the middle part of the overhead crane hook moves within the mating groove, and the servo motor drives the material stop turntable to rotate with the mating groove, so that the mating groove moves in accordance with the movement path of the overhead crane hook.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) This application, by setting a material-blocking turntable in conjunction with a guide slot plate, allows the material-blocking turntable to shield the top of the guide slot plate when the crane hook passes through the slot, using the turntable's own structure to prevent steel shot from splashing from the clearance slot. Compared to traditional soft brushes, the material-blocking turntable has a more compact sealing structure, making it difficult for steel shot to penetrate, significantly improving the leak-proof effect and reducing steel shot waste;

[0017] 2) This application drives the material stop turntable to rotate via a servo motor, so that the mating groove rotates synchronously with the movement path of the crane hook. The width of the mating groove is adapted to the diameter of the middle part of the hook, and its projection coincides with the shape of the clearance groove, which is quadrilateral. This ensures that the mating groove always corresponds to the position of the hook during the movement of the hook, avoids the sealing gap caused by the movement of the hook, achieves dynamic sealing, and further eliminates steel shot splashing.

[0018] 3) This application provides a buffer rubber layer at the bottom of the material-blocking turntable, which can buffer when the turntable comes into contact with the guide groove plate or hook, reduce mechanical wear, and extend the service life of the device. At the same time, the circumferential protective plate extends along the edge of the turntable, and the hook inlet on it corresponds to the matching groove to form a ring-shaped protective structure, which further prevents steel shot from splashing from the edge of the turntable and improves the reliability of leak prevention.

[0019] 4) This application effectively prevents steel shot from splashing outside the equipment through a multi-layered leak-proof structural design, avoiding injury to operators and eliminating safety hazards. At the same time, it reduces steel shot waste, lowers production costs, and improves the safety and economy of shot blasting operations. The overall structure of the device is highly compatible with the movement path of the overhead crane hook of the hook-type shot blasting machine. Through the linkage between the servo motor and the mechanical structure, it can be installed and used without large-scale modifications to the main body of the shot blasting machine, and has strong engineering adaptability and practicality.

[0035] Please see Figure 1-8 This utility model provides a technical solution: a leak-proof device for the feed inlet of a shot blasting machine, comprising:

[0036] Hook-type shot blasting machine 1, with a traveling hook 4 movable on the hook-type shot blasting machine 1;

[0037] The clearance groove 2 is located inside the top of the hook-type shot blasting machine 1. A guide groove plate 3 is fixedly connected to the top of the clearance groove 2. The inner side of the guide groove plate 3 is hollow.

[0038] Servo motor 5 is installed on the top of hook-type shot blasting machine 1. The motor shaft of servo motor 5 is fixedly connected to a material stop turntable 6, and a mating groove 7 is provided through the material stop turntable 6.

[0039] Specifically, the clearance groove 2 provides movement space for the hook, and the guide plate 3 plays a preliminary blocking role for the steel shot, effectively preventing the steel shot from splashing from the feed port, reducing steel shot waste and improving safety.

[0040] Specifically, please refer to the attached instruction manual. Figure 2In the prior art, in order to ensure that the crane hook 4 passes smoothly, the width of the clearance groove 2 is usually greater than the diameter of the crane hook 4, which makes it very easy for the high-speed steel shot inside the shot blasting machine to splash out from the opening of the clearance groove 2.

[0041] Reference manual attached Figure 1 and instruction manual attached Figure 3 The baffle turntable 6 is positioned above the guide slot plate 3, and is designed to shield the area above the guide slot plate 3. Specifically, by cooperating with the guide slot plate 3, a double protective structure is formed. When the crane hook 4 passes through the mating slot 7, the baffle turntable 6 can shield the area above the guide slot plate 3, using its own structure to prevent steel shot from splashing from the clearance slot 2. Compared to traditional soft brushes, the sealing structure of the baffle turntable 6 is more compact, making it difficult for steel shot to penetrate, significantly improving the leak-proof effect and reducing steel shot waste.

[0042] In some embodiments, a buffer rubber layer is provided at the bottom of the material stop turntable 6. Specifically, the buffer rubber layer can reduce the impact force when the material stop turntable 6 contacts the guide groove plate 3 or the hook, reduce component wear, extend the service life of the device, and at the same time enhance the sealing effect to prevent steel shot leakage due to contact gaps.

[0043] Reference manual attached Figure 5-8 The width of the mating groove 7 is matched with the diameter of the middle part of the crane hook 4, and the vertical projection of the mating groove 7 and the clearance groove 2 coincides in a quadrilateral shape. Specifically, this ensures that the mating groove 7 and the hook are precisely matched, maintaining a certain seal during the movement of the hook. The quadrilateral projection overlap ensures that the mating groove 7 can effectively cover the clearance groove 2 when the hook is in different positions, preventing steel shot from splashing out of the gaps and improving the reliability of leak prevention.

[0044] Reference manual attached Figure 1 and instruction manual attached Figure 4 A circumferential protective plate 8 is fixedly connected to the bottom of the material-blocking turntable 6. The circumferential protective plate 8 extends along the edge of the material-blocking turntable 6, and a hook inlet 9 is provided on the circumferential protective plate 8. The hook inlet 9 corresponds to the opening of the mating groove 7. Specifically, the circumferential protective plate 8 forms a wrap-around protective structure to prevent steel shot from splashing from the edge of the material-blocking turntable 6. The hook inlet 9 corresponds to the mating groove 7, ensuring that the hook can pass smoothly while maintaining the integrity of the protection, further improving the leak-proof effect.

[0045] Reference manual attached Figure 5-8The middle part of the crane hook 4 moves within the mating groove 7. The servo motor 5 drives the baffle turntable 6 to rotate with the mating groove 7, so that the mating groove 7 matches the movement path of the crane hook 4. Specifically, by driving the baffle turntable 6 to rotate through the servo motor 5, the mating groove 7 rotates synchronously with the movement path of the crane hook 4. The width of the mating groove 7 is adapted to the diameter of the middle part of the hook, and its shape coincides with the projection of the clearance groove 2, forming a quadrilateral shape. This ensures that the mating groove 7 always corresponds to the position of the hook during the movement of the hook, avoiding sealing gaps caused by hook movement, achieving dynamic sealing, and further preventing steel shot splashing.

[0046] Reference manual attached Figure 5 This is a schematic diagram showing the crane hook 4 entering the inlet of the guide slot 3, at which point the crane hook 4 enters the opening of the mating slot 7; refer to the attached instruction manual. Figure 6 This is a schematic diagram showing the crane hook 4 moving to the front of the guide plate 3; refer to the attached instruction manual. Figure 7 This is a schematic diagram showing the crane hook 4 moving to the middle of the guide slot plate 3; refer to the attached instruction manual. Figure 8 This is a schematic diagram of the crane hook 4 moving to the rear of the guide trough plate 3.

[0047] Specifically, in this shot blasting machine's leak-proof device, although the overlapping area of ​​the vertical projection of the mating groove 7 and the clearance groove 2 is slightly larger than the circular projection area of ​​the center of the crane hook 4, compared to the traditional clearance groove design that relies solely on a fixed opening wider than the hook diameter, the parallelogram overlapping area of ​​this device always effectively covers the clearance groove 2 during the movement of the hook 4. Combined with the double-layer protective structure of the baffle turntable 6 and the guide plate 3, this significantly reduces the gap where steel shot might splash. Even when the hook 4 is moving, the rotation of the baffle turntable 6 can promptly adjust the position of the mating groove 7, ensuring dynamic maintenance of the sealing state and greatly improving leak-proof performance. The circumferential protective plate 8 further blocks steel shot that might overflow from the edge, resulting in a qualitative improvement in overall sealing strength compared to traditional designs, effectively solving the problem of steel shot splashing caused by excessively large clearance groove openings in existing technologies.

[0048] Specifically, this application effectively prevents steel shot from splashing outside the equipment through a multi-layered leak-proof structural design, avoiding injury to operators and eliminating safety hazards. At the same time, it reduces steel shot waste, lowers production costs, and improves the safety and economy of shot blasting operations. The overall structure of the device is highly compatible with the movement path of the overhead crane hook 4 of the hook-type shot blasting machine 1. Through the linkage between the servo motor 5 and the mechanical structure, it can be installed and used without large-scale modifications to the main body of the shot blasting machine, and has strong engineering adaptability and practicality.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
