Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, and in particular to a shot material supply device for a shot blasting machine. Background Art

[0002] Shot blasting machines are a crucial piece of equipment in foundries, their primary function being to clean the surfaces of castings. The casting process produces a wide variety of castings, varying significantly in shape, size, material, and surface condition. For example, some castings may be large, complex structural components, while others may be small, precision castings. Some castings may be covered in thick scale and grit, while others may only have minor stains.

[0003] Due to this diversity of workpiece types, controlling the shot blaster's abrasive feed during the cleaning process is crucial. Different castings may require varying shot feed rates and durations. Excessive shot feed may lead to over-cleaning of some precision castings, compromising surface finish. However, insufficient shot feed may not effectively remove impurities from castings with poor surface conditions. Similarly, the feed duration must be adjusted based on the specific casting's condition.

[0004] Therefore, in order to better adapt to this complex cleaning demand, achieving precise on / off control of the shot blasting machine's shot material supply according to actual conditions has become a key factor in improving the cleaning efficiency and quality of the shot blasting machine. This can avoid unnecessary shot material waste and ensure that each casting is properly cleaned, thereby significantly improving production efficiency and also helping to improve the surface quality and overall performance of the casting.

[0030] The working principle and beneficial effects of the utility model are as follows:

[0031] In this utility model, a shot blasting machine shot blasting device is designed to address the problem of the inability to adjust the shot blasting machine's shot blasting feed rate in the related art. In actual shot blasting equipment, the shot blasting machine's storage hopper is typically located at a high position to allow gravity to smoothly drop the shot blasting material. The housing is securely attached to the lower surface of the storage hopper, ensuring a tight and seamless connection between the two to prevent shot blasting material leakage. The first feed port at the top of the housing is designed to match the shape and size of the storage hopper's discharge port, allowing shot blasting material to smoothly enter the housing from the storage hopper.

[0032] The adjustment plate is mounted on a specially designed chute that ensures smooth sliding without jamming or drifting. The shape and size of the adjustment opening on the adjustment plate are carefully designed. Initially, the opening partially overlaps with the first feed opening. The shot feed rate is adjusted by precisely controlling the overlap area. For example, to increase the shot feed rate, the operator can use a handle or electric drive to push the adjustment plate, increasing the overlap area between the opening and the first feed opening. This increases the cross-sectional area of the passage, allowing more shot to enter the housing through the first feed opening. Conversely, to decrease the shot feed rate, the adjustment plate is pushed in the opposite direction, reducing the overlap area and decreasing the shot flow rate.

[0033] The benefit is that this adjustable shot feed method greatly improves the versatility of the shot blasting machine. The required shot feed quantity may vary depending on the shot blasting operation. For example, when processing smaller workpieces, less shot feed is required to avoid over-blasting and surface damage; while when processing larger workpieces or workpieces with rough surfaces, more shot feed is required to ensure effective shot blasting. By flexibly adjusting the adjustment plate, the required shot feed quantity can be met in various working scenarios, improving the efficiency and quality of the shot blasting machine.

[0034] In addition, precise control of the shot feed rate can save shot usage and reduce production costs. At the same time, it avoids equipment failure and production interruption caused by too much or too little shot, and improves production stability and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0042] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0043] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] Reference Figures 1 to 4 , which is the first embodiment of the utility model, proposes a shot blasting machine shot material feeding device for controlling the shot blasting machine shot material supply amount, the shot blasting machine has a storage hopper 1, including a shell 2, the top of the shell 2 has a first feed port 201, the bottom of the shell 2 has a first discharge port 202, the shell 2 is arranged on the lower surface of the storage hopper 1, the first feed port 201 is connected to the storage hopper 1; the adjustment plate 3 is slidably arranged between the shell 2 and the storage hopper 1, the adjustment plate 3 has an adjustment port 301, the adjustment port 301 coincides with the first feed port 201, after the adjustment plate 3 slides, the cross-sectional area of the passage between the first feed port 201 and the storage hopper 1 is expanded or reduced.

[0046] In this embodiment, a shot blasting machine shot blasting material supply device is designed to solve the problem of the inability to adjust the shot blasting machine shot blasting material supply in the related art. In actual shot blasting machine equipment, the shot blasting machine's storage hopper 1 is usually located at a higher position so that the shot blasting material can fall smoothly due to gravity. The outer shell 2 is firmly mounted on the lower surface of the storage hopper 1, ensuring a tight and seamless connection between the two to prevent shot blasting material leakage. The first feed port 201 at the top of the outer shell 2 is designed to match the shape and size of the discharge port of the storage hopper 1, so that the shot blasting material can smoothly enter the outer shell 2 from the storage hopper 1.

[0047] The adjustment plate 3 is mounted on a specially designed chute that ensures smooth sliding without jamming or deflection. The shape and size of the adjustment opening 301 on the adjustment plate 3 are carefully designed. Initially, the adjustment opening 301 partially overlaps with the first feed opening 201. The shot feed rate is adjusted by precisely controlling the overlapping area. For example, to increase the shot feed rate, the operator can use a handle or electric drive to push the adjustment plate 3, increasing the overlapping area between the adjustment opening 301 and the first feed opening 201. This increases the cross-sectional area of the passageway, allowing more shot to enter the housing 2 through the first feed opening 201. Conversely, to decrease the shot feed rate, the adjustment plate 3 is pushed in the opposite direction, reducing the overlapping area and decreasing the shot flow rate.

[0048] The advantage is that this adjustable shot feed method greatly improves the applicability of the shot blasting machine. The amount of shot required may vary in different shot blasting operations. For example, when processing smaller workpieces, less shot is required to avoid over-blasting and surface damage; when processing larger workpieces or workpieces with rough surfaces, more shot is required to ensure effective shot blasting. By flexibly adjusting the adjustment plate 3, the required shot amount can be met in various working scenarios, improving the efficiency and shot blasting quality of the shot blasting machine.

[0049] In addition, precise control of the shot feed rate can save shot usage and reduce production costs. At the same time, it avoids equipment failure and production interruption caused by too much or too little shot, and improves production stability and reliability.

[0050] Furthermore, it also includes a transition piece 4, which is arranged in the outer shell 2, with one end of the transition piece 4 connected to the first feed port 201 and the other end leading to the first discharge port 202; one end of the rotating closure piece 5 is rotatably arranged on the transition piece 4, and after the rotating closure piece 5 rotates, the other end of the rotating closure piece 5 closes the other end of the transition piece 4.

[0051] In this embodiment, the transition piece 4 is made of high-strength, wear-resistant material to ensure it can withstand the impact and friction of the shot during long-term use. The transition piece 4 is typically tubular or funnel-shaped, with its upper end tightly connected to the first feed inlet 201 and its lower end leading to the first discharge outlet 202, forming a smooth passage for the shot. One end of the rotating closure 5 is mounted on the transition piece 4 via a sturdy shaft. The shaft design ensures that the rotating closure 5 can rotate flexibly without getting stuck or loose.

[0052] When it is necessary to stop the supply of shot, the operator can control the rotation of the closing member 5. The other end of the rotating closing member 5 completely closes the lower end outlet of the transition piece 4 to prevent the shot from continuing to fall.

[0053] The advantage is that the provision of the transition piece 4 allows the shot to smoothly transition from the first feed port 201 to the first discharge port 202, reducing resistance and energy loss during the shot flow process. The presence of the rotating closure 5 provides great convenience and safety for the operation of the shot blasting machine. When the shot blasting operation needs to be suspended, such as for equipment maintenance, workpiece replacement, or emergency response, the shot supply can be cut off in a timely manner to avoid waste of shot and pollution of the working environment. At the same time, it can also prevent the shot from continuing to fall when not needed, causing damage to equipment such as the shot blasting machine 10.

[0054] Furthermore, it also includes a first connecting rod 6, one end of the first connecting rod 6 is hingedly set on the rotating closing member 5; the first telescopic member 7 is set on the outer shell 2, the extended end of the first telescopic member 7 is located inside the outer shell 2, and the extended end of the first telescopic member 7 is hinged to the other end of the first connecting rod 6. After the first telescopic member 7 contracts, it drives the first connecting rod 6 to move.

[0055] In the present embodiment, first connecting rod 6 adopts high-strength metal material to make, and its one end is connected with rotary closure member 5 by hinge, and the other end is connected with the extended end of first telescopic member 7 by bearing pin.First telescopic member 7 is installed on the outer side wall of shell 2 usually, guarantees its stability by fixed bracket.The extended end of first telescopic member 7 is positioned in shell 2, and when first telescopic member 7 shrinks, pulls first connecting rod 6, thereby drives rotary closure member 5 to rotate.For example, in actual operation, when first telescopic member 7 receives control signal, it can stretch out rapidly, transmits power by first connecting rod 6, makes rotary closure member 5 complete rotational motion at short notice, the outlet of closed transition piece 4.

[0056] The advantage is that precise control of the first telescopic member 7 allows for a rapid response of the rotating closure member 5. During shot blasting operations, it is sometimes necessary to quickly stop the shot supply to respond to emergencies or make equipment adjustments. The first telescopic member 7 can be extended instantly, driving the rotating closure member 5 to rotate, achieving closed control of the outlet of the transition member 4 and ensuring safe operation of the shot blasting machine.

[0057] Furthermore, it also includes a limit block 8, which is arranged on the rotating closure 5; a limit rod 9 is slidably arranged on the outer shell 2, with one end located inside the outer shell 2. After the rotating closure 5 rotates, one end of the limit rod 9 abuts against the limit block 8. After the limit rod 9 slides, the rotatable angle of the rotating closure 5 increases or decreases.

[0058] In this embodiment, the stopper 8 is typically made of a sturdy metal material and is attached to the rotating closure member 5 by welding or bolting. The stopper rod 9 is mounted on the housing 2 via a sliding sleeve. The sleeve should be made of a material with excellent wear resistance and sealing properties to ensure that the stopper rod 9 slides smoothly without loosening or leakage. One end of the stopper rod 9 is located within the housing 2. When the rotating closure member 5 rotates to a certain angle, the end of the stopper rod 9 abuts the stopper block 8, limiting further rotation of the rotating closure member 5.

[0059] To adjust the rotatable angle of the rotary closure member 5, the position of the limiting rod 9 in the sliding sleeve can be adjusted manually or automatically. For example, an adjustment knob or a motor drive device can be provided on the housing 2. By rotating the adjustment knob or starting the motor, the limiting rod 9 can be moved up and down in the sliding sleeve, thereby changing the contact position between the limiting block 8 and the limiting rod 9, and thus adjusting the rotatable angle of the rotary closure member 5.

[0060] The advantage is that the rotation angle of the rotating closure member 5 can be precisely controlled, allowing for more precise adjustment of the shot flow rate. During shot blasting operations, the shot flow rate requirements can be very stringent, requiring precise control of the shot supply at each stage. By adjusting the position of the limit rod 9, the rotation angle of the rotating closure member 5 can be precisely controlled, allowing for fine-tuning of the shot flow rate, thereby improving the operating accuracy and shot quality of the shot blasting machine.

[0061] In addition, the provision of the limit block 8 and the limit rod 9 can prevent the rotating closure member 5 from excessive rotation, thereby avoiding damage to the equipment or leakage of the pellets due to excessive rotation angle. At the same time, it can also protect the first telescopic member 7 and the first connecting rod 6 and other components, extending their service life.

[0062] Furthermore, the shot blasting machine includes a shot blasting wheel 10 and a connecting pipe 11 , and the first discharge port 202 is connected to the shot blasting wheel 10 through the connecting pipe 11 .

[0063] In this embodiment, the connecting tube 11 is typically made of a wear-resistant and corrosion-resistant material, such as rubber, polyurethane, or alloy steel. One end of the connecting tube 11 is connected to the first discharge port 202 at the bottom of the housing 2 via a flange or quick connector, and the other end is connected to the shot blasting wheel 10 of the shot blasting machine. The length and diameter of the connecting tube 11 can be selected according to actual needs to ensure smooth delivery of shot from the supply device to the shot blasting wheel 10.

[0064] When installing the connecting pipe 11, ensure a tight connection without leaks. Sealing elements such as sealants, gaskets, or clamps can be used to enhance the tightness of the connection. Furthermore, the connecting pipe 11 should be arranged to avoid bending and twisting as much as possible to reduce resistance and energy loss during the pellet conveying process.

[0065] The advantage is that it provides a stable conveying channel for the shot material from the supply device to the shot blasting machine 10. The conveying of the shot material is a crucial step in the shot blasting operation. The presence of the connecting pipe 11 ensures that the shot material can be smoothly transported from the supply device to the shot blasting machine 10 without problems such as blockage or leakage. This ensures the normal operation of the shot blasting machine and improves production efficiency.

[0066] Furthermore, it also includes a scraper 12. There are two scrapers 12. The two scrapers 12 are both slidably set in the shell 2. One side of the scraper 12 abuts against the bottom of the shell 2. After sliding, the two scrapers 12 approach or move away from the first discharge port 202 from both sides.

[0067] In this embodiment, the scraper 12 is typically made of a high-strength, wear-resistant material. The scraper 12 is mounted on the inner wall of the housing 2 via a slider. The slider should be made of a material with excellent wear resistance and sliding properties to ensure that the scraper 12 can slide smoothly within the housing 2 without sticking or wear. One side of the scraper 12 is in close contact with the bottom of the housing 2, ensuring that the pellets on the bottom of the housing 2 can be effectively removed.

[0068] In the initial state, the two scrapers 12 are located on both sides of the first discharge port 202. When it is necessary to clean the pellets at the bottom of the shell 2, the operator can control the scraper 12 to slide toward the first discharge port 202 to concentrate the pellets at the first discharge port 202, thereby achieving the purpose of cleaning.

[0069] The advantage is that the shot at the bottom of the housing 2 can be promptly cleared, preventing it from accumulating and blocking the discharge port. During the shot blasting operation, shot continuously enters the housing 2 from the storage hopper 1 and is then delivered to the shot blaster 10 through the first discharge port 202. If the shot at the bottom of the housing 2 is not promptly cleared, it will accumulate and block the discharge port, affecting the normal supply of shot. The presence of the scraper 12 effectively solves this problem, ensuring smooth shot supply.

[0070] Furthermore, it also includes a sliding rod 13, which is located in the outer shell 2, and one end of the sliding rod 13 is slidably set at the bottom of the outer shell 2; there are two second connecting rods 14, one end of the two second connecting rods 14 is respectively hingedly set on the two scrapers 12, and the other ends of the two second connecting rods 14 are hingedly set at the other end of the sliding rod 13. After the sliding rod 13 slides, it drives the two scrapers 12 to slide.

[0071] In this embodiment, the sliding rod 13 is typically made of a high-strength metal material, with one end mounted to the bottom of the housing 2 via a guide rail. The guide rail should be made of a material with excellent wear resistance and sliding properties to ensure that the sliding rod 13 can slide smoothly across the bottom of the housing 2 without sticking or wear. One end of each of the two second connecting rods 14 is hinged to the two scrapers 12, and the other end is hinged to the other end of the sliding rod 13.

[0072] When the sliding rod 13 slides on the guide rail, the second connecting rod 14 drives the two scrapers 12 from both sides toward or away from the first discharge port 202. For example, when the sliding rod 13 slides to one side, the second connecting rod 14 drives the two scrapers 12 toward the center, concentrating the pellets at the first discharge port 202; when the sliding rod 13 slides to the other side, it drives the scrapers 12 to separate to prepare for the next cleaning.

[0073] The advantage is that the linkage between the sliding rod 13 and the second connecting rod 14 enables the synchronous movement of the two scrapers 12. When cleaning the pellets at the bottom of the housing 2, the synchronous movement of the two scrapers 12 improves the efficiency and effectiveness of the cleaning process. It also ensures the stability of the scrapers 12 during movement, preventing problems such as tilting or jamming.

[0074] Furthermore, it includes a connecting rod 15, one end of which is arranged at the extended end of the first telescopic member 7. After the first telescopic member 7 is retracted, the other end of the connecting rod 15 drives the second connecting rod 14 to swing, causing the sliding rod 13 to slide.

[0075] In this embodiment, the linkage rod 15 is typically made of a high-strength metal material, with one end of the linkage rod 15 bolted or welded to the extended end of the first telescopic member 7. When the first telescopic member 7 contracts, the other end of the linkage rod 15 causes the second link 14 to swing. For example, when the first telescopic member 7 contracts, the linkage rod 15 moves with the extended end of the first telescopic member 7. Through contact with the second link 14, the linkage rod 15 pushes the second link 14 to swing, thereby causing the sliding rod 13 to slide along the bottom of the housing 2.

[0076] The advantage is that a single action simultaneously controls two functions: shutting off the shot supply and clearing the bottom of the housing 2. During shot blasting operations, it is sometimes necessary to simultaneously shut off the shot supply and clear the shot from the bottom of the housing 2. The design of the linkage rod 15 allows the first telescopic member 7 to retract, not only driving the rotating closure member 5 to close the outlet of the transition member 4 and stop the shot supply, but also simultaneously driving the second connecting rod 14 to swing, causing the sliding rod 13 to slide, thereby driving the scraper 12 to clear the shot from the bottom of the housing 2.

[0077] This integrated operation method improves operational convenience and work efficiency. The operator only needs to perform one operation to complete two important tasks at the same time, reducing operational complexity and time costs.

[0078] Furthermore, an elastic member 16 is included, and two ends of the elastic member 16 are respectively in contact with the sliding rod 13 and the housing 2 to provide a force for restoring the sliding rod 13 .

[0079] In this embodiment, the elastic member 16 is typically a spring, and the material of the spring should have good elasticity and durability. The two ends of the spring abut against the sliding rod 13 and the housing 2, respectively, providing a force to return the sliding rod 13 through compression or tension. When the scraper 12 has cleared the shot, the first telescopic member 7 extends, and the elastic force of the elastic member 16 resets the sliding rod 13, driving the scraper 12 back to its initial position.

[0080] The advantage is that it provides a restoring force for the sliding rod 13, ensuring that the scraper 12 automatically returns to its initial position after completing the cleaning operation. After cleaning the pellets at the bottom of the housing 2, the scraper 12 needs to be returned to its initial position to prepare for the next cleaning operation or to await the next operation instruction. The presence of the elastic member 16 automates this process, improving the automation level and operating efficiency of the device.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
