Abstract
Description
Technical Field
[0001] The present utility model relates to the field of shot blasting machines, and specifically relates to a discharging device of a shot blasting machine. Background Art
[0002] A shot blasting machine is a device widely used in metal surface treatment. By using a high-speed rotating shot blasting device, hard particles such as steel shots and iron shots are shot at a very high speed onto the surface of the workpiece, thereby achieving the cleaning, strengthening or pretreatment of the workpiece surface.
[0003] Currently, during the discharging process of shot blasting machines, attention is often only paid to how to discharge the workpieces or materials from the shot blasting machine, while ignoring the impact of dust and impurities generated during the discharging process on the working environment and operators. If these dust and impurities are not effectively treated, they will not only pollute the working environment, but may also pose a hazard to the health of operators. Content of the Utility Model
[0004] In order to overcome the above deficiencies, the present utility model provides a discharging device of a shot blasting machine.
[0005] The technical solution adopted by the present utility model is as follows:
[0006] A discharging device of a shot blasting machine includes a discharging pipeline. The front end of the discharging pipeline is fixedly connected and communicated with a discharging interface. The front end of the discharging pipeline is inclined upward. A blanking port is opened at the rear side of the bottom of the discharging pipeline. The front end of the discharging interface is open. The rear side wall of the discharging interface is fixedly connected with a cylinder. The bottom end of the output shaft of the cylinder is fixedly connected with a baffle. The baffle is inserted into the top of the connection between the discharging interface and the discharging pipeline. The left and right side walls of the baffle are slidably matched with the left and right inner walls of the discharging pipeline. A plurality of ventilation holes are opened in the middle of the top of the discharging pipeline. The ventilation holes are distributed in a rectangular array. There is a cover plate above the ventilation holes. The left and right side edges of the cover plate are bent downward and fixedly connected with the discharging pipeline. A plurality of fixed pipes are fixedly communicated with the top of the cover plate. The fixed pipes are distributed in a rectangular array. Exhaust fans are installed in the fixed pipes. Filter cotton is filled between the cover plate and the top of the discharging pipeline.
[0007] The left and right side walls of the discharging pipeline and the discharging interface are both fixedly connected with legs extending downward. The bottom ends of the legs are rotatably connected with moving wheels.
[0008] Advantages of the Present Utility Model
[0009] By arranging ventilation holes, exhaust fans and filter cotton on the top of the discharging pipeline, the present utility model realizes the function of synchronously discharging dust during the discharging process, effectively improves the working environment, and protects the health of operators. By controlling the rising and falling of the baffle through the cylinder, the closing of the discharging interface can be controlled, which is convenient for replacing the filter cotton, with simple and quick operation, and improves work efficiency.

Specific embodiments
[0015] As Figures 1-4 shown: A discharge device of a shot blasting machine includes a discharge pipeline 2. The front end of the discharge pipeline 2 is fixedly connected and communicated with a discharge interface 1. The front end of the discharge pipeline 2 is inclined upward. A blanking port 3 is opened at the rear side of the bottom of the discharge pipeline 2. The front end of the discharge interface 1 is open. The rear side wall of the discharge interface 1 is fixedly connected with a cylinder 6. The bottom end of the output shaft of the cylinder 6 is fixedly connected with a baffle 7. The baffle 7 is inserted into the top of the connection between the discharge interface 1 and the discharge pipeline 2. The left and right side walls of the baffle 7 are in sliding fit with the left and right inner walls of the discharge pipeline 2. A plurality of ventilation holes 8 are opened in the middle of the top of the discharge pipeline 2. The ventilation holes 8 are distributed in a rectangular array. A cover plate 9 is arranged above the ventilation holes 8. The left and right side edges of the cover plate 9 are bent downward and fixedly connected with the discharge pipeline 2. A plurality of fixed pipes 10 are fixedly communicated with the top of the cover plate 9. The fixed pipes 10 are distributed in a rectangular array. Exhaust fans 11 are installed in the fixed pipes 10. Filter cotton 12 is filled between the cover plate 9 and the top of the discharge pipeline 2.
[0016] Support legs 4 extending downward are fixedly connected to the left and right side walls of the discharge pipeline 2 and the discharge interface 1. The bottom ends of the support legs 4 are rotatably connected with moving wheels 5.
[0017] After the shot blasting machine finishes working and needs to discharge materials, first ensure that the baffle 7 is in the closed state, that is, the output shaft of the cylinder 6 pushes the baffle 7 to the bottom of the connection between the discharge interface 1 and the discharge pipeline 2, completely blocking the discharge interface 1 to prevent premature leakage of materials.
[0018] When discharging materials is required, the cylinder 6 is started, and the output shaft of the cylinder 6 retracts, driving the baffle 7 to move upward, thereby opening the discharge interface 1, enabling the materials in the shot blasting machine to smoothly enter the discharge pipeline 2. Since the front end of the discharge pipeline 2 is inclined upward, the materials will slide downward along the pipeline under the action of gravity and be discharged from the discharge opening 3.
[0019] While the materials are being discharged, the exhaust fan 11 starts to work. The exhaust fan 11 extracts the air in the discharge pipeline 2 through the fixed pipe 10 to form a negative pressure environment. Since the ventilation holes 8 are located in the middle of the top of the discharge pipeline 2 and are distributed in a rectangular array, the air and entrained dust in the pipeline can be evenly extracted.
[0020] The extracted air and dust enter the space below the cover plate 9 through the ventilation holes 8, and then are filtered by the filter cotton 12. The filter cotton 12 can effectively intercept the dust particles in the air, and the clean air is discharged to the external environment through the exhaust fan 11.
[0021] After all the materials in the shot blasting machine are completely discharged through the discharge pipeline 2, the cylinder 6 is started again to push the baffle 7 back to the closed position to block the discharge interface 1, completing the discharging process.
[0022] When the filter cotton 12 needs to be replaced, the discharge interface 1 is blocked by the baffle 7, the old filter cotton 12 is taken out, and the new filter cotton 12 is filled inside the cover plate 9. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
