[0002] Shot blasting machines utilize high-speed steel shot to impact the surface of parts, achieving cleaning and finishing purposes. The process produces virtually no silicon powder, resulting in almost zero pollution. It is suitable for cleaning sand, removing rust, removing oxide scale, and surface strengthening of cast steel, gray castings, malleable iron, and ductile iron parts in various industries. It is also an indispensable preparatory step before casting quality inspection; for example, the outer surface of a clutch housing requires shot blasting for finishing. The primary purpose of shot blasting machines is to remove burrs from die castings and achieve decorative surface quality, resulting in excellent performance.

[0003] After shot blasting, the workpieces often contain rust and dust. It is difficult to separate these tiny impurities manually, and the separation effect is also poor. However, some workpieces often need to be shot blasted repeatedly, and the rust and dust mixed in will have a significant impact on the shot blasting effect. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a shot blasting cleaning device, which has the following beneficial effects:

[0013] (1) The shot blasting cleaning device drives the first servo motor to drive the spiral blades to rotate through the first rotating shaft, thereby transporting the shot from the bottom of the transfer barrel to the top. Since there is a filter screen between the transfer barrel and the collection box at its bottom, the impurities mixed in the shot will be screened into the collection box by the filter screen during the transmission of the shot in the inner cavity of the transfer barrel. At the same time as the shot is being transported, it can be initially cleaned, which is convenient for further screening.

[0014] (2) In this shot blasting cleaning device, when the shot enters the inner cavity of the chamber, it will fall directly onto the surface of the filter plate. The rotating column drives the extrusion column to rotate. During the rotation of the extrusion column, the filter plate will be squeezed upward, causing the spring to generate a rebound force. At the same time, the rebound force of the spring is used to make the filter plate vibrate, which can enhance the screening ability of the filter plate. Attached Figure Description

[0019] 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.

[0020] Reference Figures 1-3 A shot blasting cleaning device includes a housing 1, a conveying assembly 2 installed on the side wall of the housing 1 for conveying shot to the inner cavity of the housing 1, a screening assembly 3 installed in the inner cavity of the housing 1 for screening impurities in the shot, and further includes:

[0021] The transmission component 2 includes a connecting box 201, which is fixedly installed on the top side of the box 1. A transmission bucket 202 is fixedly connected to the top of the connecting box 201. A first servo motor 203 is fixedly connected to the end of the transmission bucket 202. A first rotating shaft 204 is fixedly connected to the output end of the first servo motor 203. A spiral blade 205 is fixedly connected to the side wall of the first rotating shaft 204. A collection box 206 is fixedly connected to the bottom of the transmission bucket 202. A filter screen is provided between the collection box 206 and the transmission bucket 202.

[0022] A feed pipe 207 is fixedly connected to the top of the transfer bucket 202. The top of the feed pipe 207 is set to be open. A connecting pipe 208 is fixedly connected between the transfer bucket 202 and the connecting box 201.

[0023] A second servo motor 209 is fixedly connected to the side wall of the connecting box 201. A second rotating shaft 210 is fixedly connected to the output end of the second servo motor 209. Multiple sets of rotating plates 211 are fixedly connected to the side wall of the second rotating shaft 210, and the rotating plates 211 are in contact with the inner wall of the connecting box 201.

[0024] It should be noted that: the shot is fed into the inner cavity of the transfer tank 202 through the feed pipe 207, and at the same time the first servo motor 203 is driven. The first servo motor 203 drives the spiral blade 205 to rotate through the first rotating shaft 204, thereby transferring the shot from the bottom to the top of the transfer tank 202. Since there is a filter screen connected between the transfer tank 202 and the collection box 206 at its bottom, the impurities mixed in with the shot will be screened into the collection box 206 during the transfer of the shot in the inner cavity of the transfer tank 202. The shot can be initially cleaned while it is being transferred. After the shot is transferred to the top of the transfer tank 202, it enters the inner cavity of the connecting box 201 through the connecting pipe 208, and drives the second servo motor 209 to drive the rotating plate 211 to rotate through the second rotating shaft 210. During the rotation of the rotating plate 211, the shot can be restricted from entering the inner cavity of the box 1, which is convenient for further screening.

[0025] Reference Figures 1-3 The screening component 3 includes a filter plate 301, which is slidably installed on the inner wall of the housing 1. A spring 302 is fixedly connected between the filter plate 301 and the inner wall of the housing 1. The filter plate 301 is set in an inclined position.

[0026] A rotating column 303 is rotatably connected to the inner wall of the housing 1. A squeezing column 304 is fixedly connected to the side wall of the rotating column 303, and the squeezing column 304 can fit against the bottom of the filter plate 301. A partition 305 is fixedly connected to the inner wall of the housing 1.

[0027] It should be noted that when the shot enters the inner cavity of the chamber 1, it will fall directly onto the surface of the filter plate 301. The filter plate 301 can screen out impurities on the surface of the shot. The rotating column 303 can drive the extrusion column 304 to rotate. During the rotation of the extrusion column 304, the filter plate 301 will be squeezed upward, which will stretch the spring 302 and make it rebound. The rebound force of the spring 302 will make the filter plate 301 vibrate, which can enhance the screening ability of the filter plate 301.

[0028] Reference Figures 1-3 The second rotating shaft 210 and the side wall of the rotating column 303 are both fixedly connected to pulleys, and belts 4 are rotatably connected between the pulleys;

[0029] A first collection chamber 401 is provided in the inner cavity of the left side box 1 located on the partition 305, and a second collection chamber 402 is provided in the inner cavity of the right side box 1 located on the partition 305.

[0030] It should be noted that the second rotating shaft 210 can drive the rotating column 303 to rotate through the pulley and belt 4, so as to make the filter plate 301 vibrate. The first collection chamber 401 is used to collect impurities in the shot blasting, while the second collection chamber 402 can collect the cleaned shot.

[0031] Operation method: The shot is fed into the inner cavity of the transfer tank 202 through the feed pipe 207. At the same time, the first servo motor 203 is driven. The first servo motor 203 drives the spiral blade 205 to rotate through the first rotating shaft 204, thereby transferring the shot from the bottom to the top of the transfer tank 202. Since there is a filter screen connected between the transfer tank 202 and the collection box 206 at its bottom, the impurities mixed in with the shot will be screened into the collection box 206 during the transfer of the shot in the inner cavity of the transfer tank 202. The shot can be initially cleaned while it is being transferred. After the shot is transferred to the top of the transfer tank 202, it enters the inner cavity of the connecting box 201 through the connecting pipe 208. The second servo motor 209 drives the rotating plate 211 to rotate through the second rotating shaft 210. During the rotation of the rotating plate 211, the shot can be restricted from entering the inner cavity of the box 1, which is convenient for further screening.

[0032] When the shot enters the inner cavity of the chamber 1, it falls directly onto the surface of the filter plate 301. The filter plate 301 can screen out impurities from the surface of the shot. The rotating column 303 drives the extrusion column 304 to rotate. During the rotation of the extrusion column 304, the filter plate 301 is squeezed upward, which in turn stretches the spring 302, causing it to rebound. The rebound force of the spring 302 causes the filter plate 301 to vibrate, which can enhance the screening ability of the filter plate 301. The first collection chamber 401 is used to collect impurities in the shot, while the second collection chamber 402 can collect the cleaned shot.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
