Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a tracked shot blasting cleaning 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 within the chamber, achieving the cleaning purpose. They are suitable for cleaning sand, removing rust, removing oxide scale, and surface strengthening of small castings, forgings, stampings, gears, springs, etc., and are particularly suitable for cleaning and strengthening parts that are not susceptible to impact.

[0003] Tracked shot blasting machines typically reuse shot, but because the shot may contain impurities that fall with it, it needs to be separated before it can be reused.

[0004] Existing technologies, such as the tracked shot blasting machine with application number "202021743976.5", can separate shot and impurities, but require the shot to be piled up to a certain amount before being introduced into the shot blasting machine for use. It is difficult to achieve continuous reuse of shot, and it takes time and effort to pour the collected shot back in, so it is not convenient to use.

[0005] Therefore, a tracked shot blasting machine is proposed. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a tracked shot blasting machine.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A tracked shot blasting machine includes a shot blasting machine housing, a screw conveyor for conveying shot, a hoist for lifting and projecting shot, a track drive assembly for conveying workpiece, and a control system. The shot blasting machine housing is hinged with a movable door panel. The output end of the hoist is provided with a guide groove for guiding the shot, causing it to be projected above the track drive assembly. An inclined filter screen is installed inside the shot blasting machine housing. A through groove is formed on the shot blasting machine housing, with the through groove corresponding to the lower part of the filter screen. A first feed chute is formed on the housing of the screw conveyor, with the first feed chute corresponding to the through groove.

[0009] Furthermore, a first baffle is provided at the top of the screw conveyor, which is located between the shot blasting machine housing and the screw conveyor, and a second feed chute is provided at the top of the first baffle.

[0010] Furthermore, the filter screen has filter holes with a diameter length smaller than that of the projectile, and the filter screen is positioned directly below the track drive assembly.

[0011] Furthermore, a vibration motor is installed on the filter screen.

[0012] Furthermore, the internal casing of the shot blasting machine is equipped with multiple second baffles, which are arranged according to the tilt direction of the filter screen.

[0027] like Figure 1-3As shown, a tracked shot blasting machine includes a shot blasting machine housing 1, a screw conveyor 2 for conveying shot, an elevator 3 for lifting and projecting shot, a track drive assembly 7 for conveying workpiece, and a control system. A movable door panel 101 is hinged to the shot blasting machine housing 1. A guide groove 4 is provided at the output end of the elevator 3 to guide the shot, causing it to be projected above the track drive assembly 7. An inclined filter screen 8 is provided inside the shot blasting machine housing 1. A through groove is provided on the shot blasting machine housing 1, with the low position of the through groove corresponding to the low position of the filter screen 8. A first feed groove is provided on the housing of the screw conveyor 2, with the position of the first feed groove corresponding to the through groove. Specifically, the elevator 3 can lift the shot upwards to a suitable height. The impeller inside the guide groove 4 can throw the shot out at high speed. The screw conveyor 2, the elevator 3, and the track drive assembly 7 are all existing technologies, so their structures will not be described in detail here. The track in the track drive assembly 7 is hollow, so during shot blasting, the shot and debris can fall downwards onto the filter screen 8. The shot and debris can be separated by the filter screen 8. The shot can be blocked above the filter screen 8, and then, under the action of gravity, it can fall into the screw conveyor 2 through the through groove and the first feed groove, thereby conveying the shot towards the elevator 3. In order to clean up fine impurities, a dust suction structure can be set at the position of the guide groove 4, which is existing technology, so it will not be described in detail here.

[0028] like Figure 3 As shown, a first baffle 6 is provided at the top of the screw conveyor 2. The first baffle 6 is located between the shot blasting machine housing 1 and the screw conveyor 2. A second feed chute is provided at the top of the first baffle 6. Specifically, the first baffle 6 can block the shot and prevent it from falling to the ground. The second feed chute can facilitate the replenishment of shot.

[0029] like Figure 3 As shown, the filter screen 8 has filter holes with a diameter and length smaller than the diameter of the projectile, and the filter screen 8 is located directly below the track drive assembly 7.

[0030] like Figure 3 As shown, a vibration motor 9 is installed on the filter screen 8; specifically, the vibration motor 9 can accelerate the separation of projectiles and debris.

[0031] like Figure 3 As shown, the internal housing 1 of the shot blasting machine is equipped with multiple second baffles 11, which are arranged according to the tilt direction of the filter screen 8. Specifically, the second baffles 11 can slow down the rolling of the shot, thus extending the time it stays on the surface of the filter screen 8.

[0032] like Figure 3 As shown, the shot blasting machine housing 1 is equipped with multiple electromagnets 10 inside. The electromagnets 10 are arranged according to the tilt direction of the filter screen 8 and are located below the filter screen 8. Specifically, when the debris falls down, iron-containing impurities can be magnetically attracted by the electromagnets 10, while paint impurities can fall down into the collection frame 5 for collection.

[0033] like Figure 3 As shown, a collection frame 5 is slidably disposed inside the housing 1 of the shot blasting machine, and the collection frame 5 is disposed below the electromagnet 10.

[0034] In summary: When the workpiece is placed on the track drive assembly 7, it is driven to tumble under its transmission action. At the same time, the shot is thrown onto the surface of the track drive assembly 7 by the screw conveyor 2, the elevator 3, and the impeller, thus polishing the workpiece. Since the track in the track drive assembly 7 is hollow, the shot and debris can fall downwards onto the filter screen 8 during shot blasting. The shot and debris are separated by the filter screen 8. The shot is blocked above the filter screen 8 and then falls into the screw conveyor 2 through the through groove and the first feed chute under the action of gravity, thus conveying the shot towards the elevator 3 for reuse. The debris falls downwards and, when it passes the electromagnet 10, the iron-containing impurities are magnetically attracted by the electromagnet 10, while the paint impurities fall downwards into the collection frame 5 for collection.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
