Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine that is easy to clean. Background Technology

[0002] A shot blasting machine is a type of equipment used for surface treatment. It mainly uses high-speed blasting of abrasive particles such as steel shot and steel grit to impact the surface of a workpiece, thereby achieving the purpose of cleaning, strengthening, rust removal, or surface pretreatment.

[0003] To overcome the above-mentioned defects, a prior art Chinese patent (publication number: CN221248423U) discloses a shot blasting machine that is easy to clean, belonging to the field of shot blasting machine technology. This easy-to-clean shot blasting machine includes a processing chamber, a chamber door rotatably connected to the outer circumference of the processing chamber, and a shot blasting mechanism fixedly connected to the outer circumference of the processing chamber. The shot blasting mechanism is connected to the inner cavity of the processing chamber, and a mounting frame is fixedly connected to the inner wall of the processing chamber. A reduction motor is fixedly connected to the center of the mounting frame. It allows the workpiece to be placed on the upper end of the processing platform, the chamber door to be closed, and then the shot blasting mechanism and reduction motor to be started. The shot blasting mechanism can propel steel shot at high speed to process the surface of the workpiece. The reduction motor, in conjunction with the processing platform, can drive the workpiece to rotate, thereby ensuring that the surface of the workpiece is fully processed. The propelled steel shot then enters a collection box along the inner bottom of the processing chamber for centralized collection, making it convenient for personnel to clean after processing.

[0004] Although the existing technology can overcome the shortcomings mentioned above, there are still other problems in its operation: during the use of the shot blasting machine, the shot will collide with the workpiece, and the shot will break during the collision. The mixture of broken shot and impurities will remain inside the device, and the mixture of broken shot and impurities is not easy to separate, making it difficult to clean. Utility Model Content

[0005] The purpose of this invention is to provide a shot blasting machine that is easy to clean, in order to solve the problem in the above-mentioned background technology that the mixture of broken shot and impurities is retained inside the device and that the mixture of broken shot and impurities is difficult to separate, making it difficult to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine that is easy to clean, including a protective box, wherein a door is hinged to one side of the protective box, and a separation structure is provided at the bottom of the door;

[0007] The protective box has a discharge port in the middle of the bottom, and the bottom of the inner side of the protective box has an inclined surface that slopes towards the discharge port. The separation structure includes a collection pipe fixedly connected to the bottom of the protective box, and a filter screen is slidably connected inside the collection pipe. A first diversion pipe that slopes downward is fixedly connected to the outer side of the collection pipe, and the first diversion pipe and the filter screen are distributed in parallel.

[0008] The top inner side of the protective box is equipped with a hoisting structure for hoisting workpieces.

[0009] Preferably, the upper end of the collecting pipe is aligned with the discharge port, and the end of the first diverting pipe away from the collecting pipe is fixedly connected to a separating pipe that is distributed parallel to the collecting pipe.

[0010] Preferably, a second diversion pipe is fixedly connected between the separation pipe and the collecting pipe, and the second diversion pipe and the first diversion pipe are vertically distributed. An air supply pipe is provided on the side of the separation pipe away from the second diversion pipe, and the air supply pipe is connected to an air supply device.

[0011] Preferably, a motor is fixedly connected to the top of the protective box, and the output end of the motor extends into the interior of the protective box and is connected to the hoisting structure.

[0012] Preferably, the hoisting structure includes a turntable connected to the motor output end, and the turntable has equally spaced mounting holes on its side. A gear is rotatably connected in the mounting hole, and damping is provided at the connection between the mounting hole and the gear.

[0013] Preferably, a hook is fixedly connected to the bottom of the gear, and a toothed ring meshes with the outside of the gear. A fixing ring is fixedly connected to the outside of the toothed ring, and the fixing ring is fixed to the inside of the protective box.

[0014] Preferably, the protective box is provided with shot blasting tubes that are evenly distributed on the outside, and a shot blaster is installed on the outside of the shot blasting tubes, with the shot blasting tubes facing the center of the interior of the protective box.

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

[0016] This easy-to-clean shot blasting machine effectively separates broken shot and light impurities from whole shot through a sliding filter screen inside the collection pipe and a multi-stage airflow separation structure. The mixture that is not fully separated can be returned for further screening, which significantly improves shot recovery rate and impurity removal efficiency, reduces shot wear, and keeps the equipment clean.

[0017] The hoisting structure uses a motor to drive a turntable and gears to mesh with a gear ring, ensuring continuous rotation and self-rotation of the hook and the hoisted workpiece within the protective box. This allows for adjustable workpiece posture and, in conjunction with the shot blaster, uniform irradiation, improving surface cleaning effectiveness and work efficiency. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1 - Figure 4This utility model provides the following technical solution: a shot blasting machine that is easy to clean, including a protective box 1, a door 2 hinged to one side of the protective box 1, and a separation structure at the bottom of the door 2; a discharge port 3 is provided in the middle of the bottom of the protective box 1, and an inclined surface inclined towards the discharge port 3 is provided on the bottom inner side of the protective box 1; the separation structure includes a collecting pipe 4 fixedly connected to the bottom of the protective box 1, and a filter screen 5 slidably connected inside the collecting pipe 4; a downwardly inclined first diversion pipe 6 is fixedly connected to the outside of the collecting pipe 4, and the first diversion pipe... Pipe 6 and filter screen 5 are distributed in parallel; a lifting structure for lifting workpieces is provided on the top of the inner side of the protective box 1; the upper end of the collecting pipe 4 is aligned with the discharge port 3, and a separation pipe 9 distributed in parallel with the collecting pipe 4 is fixedly connected to the end of the first diversion pipe 6 away from the collecting pipe 4; a second diversion pipe 8 is fixedly connected between the separation pipe 9 and the collecting pipe 4 at an incline, and the second diversion pipe 8 and the first diversion pipe 6 are distributed vertically, and an air supply pipe 7 is provided on the side of the separation pipe 9 away from the second diversion pipe 8, and the air supply pipe 7 is connected to the air supply equipment.

[0027] The shot blasting machine uses the shot blaster 18 inside the protective box 1 to impact the workpiece with high-speed shot, thus completing the surface cleaning. During operation, after the box door 2 is opened, the workpiece is suspended on the hook 14 of the hoisting structure. The mixture of shot and impurities generated during the shot blasting process slides down the inclined surface at the bottom of the protective box 1 due to gravity and enters the collection pipe 4 through the discharge port 3. The sliding filter 5 inside the collection pipe 4 performs initial screening of the mixture. Debris and fine impurities are directly discharged through the holes of the filter 5; larger impurities that do not pass through the filter and intact shot are guided into the separation pipe 9 by the first diversion pipe 6.

[0028] During the airflow separation stage, the air supply equipment connected to the air supply pipe 7 blows high-speed airflow into the separation pipe 9. The intact bullets, due to their large mass, overcome the airflow resistance and fall vertically for recovery, while the broken bullets and light impurities are carried by the airflow to the second diversion pipe 8. The second diversion pipe 8 and the collection pipe 4 form a return path, allowing the insufficiently separated mixture to return to the collection pipe 4 for secondary screening. This separation process significantly reduces bullet loss, improves impurity removal efficiency, and avoids the accumulation of impurities at the bottom of the protective box 1.

[0029] Example 2: Based on Example 1, please refer to... Figure 5 - Figure 6The hoisting structure was also disclosed, and its specific structure is as follows: a motor 10 is fixedly connected to the top of the protective box 1, and the output end of the motor 10 extends into the interior of the protective box 1 and is connected to the hoisting structure; the hoisting structure includes a turntable 11 connected to the output end of the motor 10, and the turntable 11 has equidistantly distributed mounting holes 12 on its side, a gear 13 is rotatably connected in the mounting holes 12, and a damping is provided at the connection between the mounting holes 12 and the gear 13; a hook 14 is fixedly connected to the bottom of the gear 13, and a toothed ring 16 meshes with the outside of the gear 13, a fixing ring 15 is fixedly connected to the outside of the toothed ring 16, and the fixing ring 15 is fixed to the inside of the protective box 1; shot blasting pipes 17 are equidistantly distributed on the outside of the protective box 1, and a shot blaster 18 is installed on the outside of the shot blasting pipes 17, with the shot blasting pipes 17 facing the center inside the protective box 1.

[0030] During the operation of the device, the motor 10 will drive the turntable 11 to rotate. At this time, the turntable 11 will drive the gear 13 and the hook 14 installed at its bottom to rotate, thereby driving the workpiece hoisted on the hook 14 to rotate inside the protective box 1. During the rotation of the gear 13 inside the mounting hole 12, it will pass through the inner side of the gear ring 16. Since the gear 13 meshes with the fixed gear ring 16, the gear 13 rotates around its own axis during the revolution, thereby driving the hook 14 and the workpiece hoisted by the hook 14 to rotate, and adjusting the orientation angle of the hoisted workpiece and the shot blasting tube 17.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] 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.
