Description
Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a dustproof tracked shot blasting machine. Background Technology
[0002] For various mechanical parts, such as shafts, gears, and flanges, a dustproof tracked shot blasting machine is used for pretreatment before surface treatments such as heat treatment, electroplating, and spraying. This removes impurities such as oxide scale and oil stains from the surface of the parts, ensuring the surface cleanliness meets requirements, enhancing the adhesion between the subsequent surface treatment layer and the substrate, and improving the quality and effect of the surface treatment.
[0003] In some existing technologies, steel shot and impurities are separated by their different settling velocities under gravity. During the operation of a shot blasting machine, the ejected steel shot and sand particles flow from small holes in the conveyor belt into a screw conveyor at the bottom, and then are fed into an elevator, which lifts them into a separator. Inside the separator, the steel shot, due to its greater gravity, settles to the bottom more quickly, while lighter impurities such as dust are separated out by airflow.
[0004] However, in actual use, steel shot that has not been cleaned by vibrating screen will contain a large amount of impurities removed from the workpiece surface, such as oxide scale, rust, and dust. These impurities will be blasted onto the workpiece surface along with the steel shot, which not only fails to effectively clean the workpiece but may also cause secondary pollution on the workpiece surface, resulting in substandard workpiece surface cleanliness and affecting the quality of subsequent coating, electroplating, and other processes. To address the above problems, a dustproof tracked shot blasting machine is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a dustproof tracked shot blasting machine, which aims to improve the problem that some existing devices cannot perform vibratory sieving and cleaning of steel shot.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the motor drives the concave cam to rotate via the drive rod, so that the concave cam can strike the screen plate, which in turn causes the screen plate to compress the spring, causing the spring to deform. This allows the screen plate to slide inside the sliding rod and then slide outside the sliding rod. Vibrating screen cleaning can remove dust, oxide scale and other impurities from the steel shot, keeping the steel shot participating in shot blasting pure. This ensures that the steel shot impacts the workpiece surface in the best condition, effectively removing rust, oil and burrs from the workpiece surface, and improving the cleanliness of the workpiece.
[0025] 2. In this utility model, the plate to be cleaned is pressed against the anti-deviation plates on both sides, which in turn press against the sliding rod two. The sliding rod two slides inside the housing through the limiting plate. When the sliding rod two slides inside the housing, the spring two deforms. When the cleaned plate is removed from the machine, the spring two rebounds, which in turn resets the anti-deviation plate. The plate does not deviate during shot blasting, ensuring that all areas of its surface can receive the impact of steel shot evenly. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1 to 3 This utility model provides an embodiment of a dustproof tracked shot blasting machine, comprising a machine body 1, a vibrating screen cleaning mechanism fixedly connected inside the machine body 1, and track rollers 24 fixedly connected to the left and right sides of the top of the machine body 1. The track rollers 24 are usually made of high-strength alloy steel and have good wear resistance and toughness after special heat treatment. A track body 11 is sleeved on the outside of the track rollers 24. The track body 11 is generally composed of multiple high-strength chain links connected by pins. The surface of the chain links has undergone special hardening treatment, which not only can withstand large tensile forces, but also maintain a stable operating state under long-term shot blasting impact. It is used to carry the workpieces that need to be shot blasted and drive the workpieces to move in the machine body 1 according to a predetermined trajectory. Multiple anti-deviation mechanisms are fixedly connected to the left and right sides of the top of the machine body 1. The anti-deviation mechanisms include angle steel 12. The angle steel 12 is used as a basic support component and is made of high-quality carbon structural steel, which has high strength and rigidity.
[0036] An extension plate 13 is externally fixed to the angle steel 12. The extension plate 13 is generally made of steel plate of moderate thickness and formed by cutting, stamping and other processing processes. Its function is to effectively connect the angle steel 12 with subsequent components and provide a certain installation space. The extension plate 13 is externally fixed to the housing 14. The housing 14 is usually made of aluminum alloy casting, which has the advantages of light weight and corrosion resistance. It has a precision sliding connection structure inside for installing the reset assembly. The reset assembly is slidably connected inside the housing 14. The reset assembly includes a limit plate 15. The limit plate 15 is made of wear-resistant engineering plastic. Its shape and size are precisely matched with the sliding groove inside the housing 14, which can slide smoothly in the housing 14 and limit the movement range of the sliding rod 16. The limit plate 15 is externally fixed to the sliding rod 16. The sliding rod 16 is generally made of stainless steel, which has good rust resistance and mechanical strength.
[0037] A spring 17 is sleeved on the outside of the sliding rod 16. The spring 17 is made of high-quality spring steel and has a suitable elastic coefficient and fatigue life after special winding and heat treatment. The other end of the sliding rod 16 is fixedly connected to an anti-deviation plate 18. The limit plate 15 is externally slidably connected to the inside of the housing 14. The reset assembly is externally fixedly connected to an anti-deviation plate 18. The anti-deviation plate 18 is generally made of elastic materials such as rubber. Its surface is designed with special textures to increase the friction with the track body 11 without damaging the track. The angle steel 12 is externally fixedly connected to the left and right sides of the cleaning machine body 1. The top four corners of the cleaning machine body 1 are fixedly connected to a connecting plate 19. The connecting plate 19 is usually made of rectangular steel plate and has been processed by drilling, chamfering and other processes. The top of the connecting plate 19 is fixedly connected to a shot blasting cleaning mechanism.
[0038] The vibrating screen cleaning mechanism includes a mounting frame 2, which is generally welded from high-strength channel steel, possessing good stability and load-bearing capacity, and providing solid support for the internal drive components. The drive components, including a motor 3, are fixedly connected inside the mounting frame 2. The motor 3 is a high-efficiency, energy-saving three-phase asynchronous motor 3, which has good starting performance and operational stability, and can continuously provide stable power output. A drive rod 4 is fixedly connected to the drive end of the motor 3. The motor 3 is externally fixedly connected inside the mounting frame 2. Multiple concave cams 5 are externally fixedly connected to the drive components. These concave cams 5 are typically forged from high-quality carbon steel, and through machining and heat treatment processes, their surface hardness and wear resistance are significantly improved. These concave cams 5 have a unique shape design; their surface concave-convex structure can generate periodic forces with the screen plate 8 during rotation, thereby causing the screen plate 8 to vibrate at high frequency.
[0039] The cleaning machine body 1 has an internal fixed connection to a mounting plate 6. The mounting plate 6 is typically made of steel plate of suitable thickness, processed through cutting and drilling. Its function is to provide an installation base for the anti-fall component. The mounting plate 6 internally has a fixed connection to the anti-fall component, which includes a fixing plate 7. The fixing plate 7 is usually made of rectangular steel plate with precisely machined grooves at its four corners for sliding connection with the sliding rod 9. The fixing plate 7 is externally slidably connected to the sliding rod 9, which is generally made of stainless steel, providing good rust resistance and mechanical strength. A spring 10 is fitted around the sliding rod 9. The spring 10 is made of high-quality spring steel and has undergone special winding and heat treatment processes, giving it a suitable elastic coefficient and fatigue life. The sliding rod 9 is slidably connected to a screen plate 8. When the screen plate 8 is subjected to external impact or vibration, the sliding rod 9 will slide in the groove of the fixed plate 7, and the spring 10 will extend and retract accordingly according to the movement state of the screen plate 8, playing a role in buffering and limiting, and preventing the screen plate 8 from falling off due to excessive vibration. The fixed plate 7 is externally fixedly connected to the four corners of the mounting plate 6, and the mounting bracket 2 is externally fixedly connected to the right side of the cleaning machine body 1.
[0040] Reference Figures 3 to 6 The shot blasting cleaning mechanism includes a connecting plate 19, which is usually made of thick rectangular steel plate. The four corners of the steel plate are pre-drilled with precision, and the plate is tightly fixed to the four corners of the cleaning machine body 1 with high-strength bolts. The top plate 20 is connected to the top of the connecting plate 19. The top plate 20 is made of alloy steel plate with good strength and toughness and is formed by cutting, grinding and other processes. The connecting rod 21 is fixedly connected inside the top plate 20. The connecting rod 21 is generally made of high-strength stainless steel and has excellent rust prevention and wear resistance.
[0041] The connecting rod 21 is externally slidably connected to a shot blasting machine 22. The shot blasting machine 22 is a key component of the entire shot blasting cleaning mechanism, equipped with a high-speed rotating impeller and a precisely controlled shot conveying system. The cleaning machine body 1 is internally slidably connected to a steel shot storage box 23. The steel shot storage box 23 is generally welded from robust cold-rolled steel plates and has a large storage space for storing large quantities of steel shot. The connecting plate 19 is externally fixedly connected to the four corners of the cleaning machine body 1. The outside of the screen plate 8 contacts the outside of the fixed plate 7. The outside of the screen plate 8 is slidably connected to the inside of the mounting plate 6. One end of the spring 10 is fixedly connected to the top of the screen plate 8, and the other end of the spring 10 is fixedly connected to the bottom of the fixed plate 7.
[0042] Working principle: By starting the motor 3, the motor 3 drives the concave cam 5 to rotate through the drive rod 4. The rotation of the concave cam 5 causes the concave cam 5 to strike the screen plate 8, which in turn causes the screen plate 8 to compress the spring 10. Under the action of the spring 10, the spring 10 deforms, which in turn causes the screen plate 8 to slide inside the sliding rod 9, and then slide outside the sliding rod 9, so that the screen plate 8 will not detach from the interior of the cleaning machine body 1.
[0043] When the plate to be cleaned is placed outside the track body 11, it presses against the anti-deviation plates 18 on both sides, causing the anti-deviation plates 18 to press against the sliding rod 16. The sliding rod 16 slides inside the housing 14 through the limiting plate 15. When the sliding rod 16 slides inside the housing 14, the spring 17 deforms. When the cleaned plate is removed from the machine, the spring 17 rebounds, causing the anti-deviation plates 18 to reset, thus preventing the plate to be cleaned from detaching from the track body 11.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
