[0002] A hook type shot blasting machine suspends metal parts inside the equipment through a hook, and then inside the machine, the metal surface is cleaned by a high-speed rotating shot blasting ejector. The steel shots or other abrasive substances in the shot blasting ejector will impact the metal surface at high speed, washing away the dirt and oxides on its surface, thus completing the cleaning process.

[0003] When the steel shots after shot blasting in the existing shot blasting machine enter the separator, they are prone to accumulate in one place and are not easy to disperse. At the same time, the steel shots and sundries enter the separator for screening, causing the filter screen to screen too many sundries at the same time. The screening amount of the filter screen is large, which easily causes the filter screen to become blocked and affects the separation efficiency. Content of the Utility Model

[0004] For this reason, the utility model provides a shot material separator for a hook type shot blasting machine. Through the cooperation of a fan blade and a filter screen, it solves the problems that when the steel shots enter the separator, they are prone to accumulate in one place, and at the same time, the filter screen screens too many sundries, the screening amount of the filter screen is large, and it is easy to cause the filter screen to become blocked.

A driving component is sleeved outside the transmission shaft 13 and the connecting shaft 17;

[0026] In this implementation scheme, in order to achieve the purpose of preliminarily cleaning the waste before screening the steel shot and waste, reducing the screening amount of the filter screen, and at the same time preventing the steel shot and waste from accumulating on the filter screen and being inconvenient to spread out, the fan blade 14 rotates to make the air blow into the isolation cover 7 through the ventilation net 8, blowing out the light impurities in the steel shot and waste outside the isolation cover 7, and making the light impurities slide out of the separation box 1 through the inclined surface of the waste material falling plate 9 from the waste port 3. The steel shot and waste after preliminary cleaning fall on the top of the filter screen 10, achieving the purpose of reducing the screening amount of the filter screen 10, and further preventing the filter screen 10 from being blocked due to a large screening amount during screening. The cam 18 rotates to make the filter screen 10 in a vibrating state, shaking the steel shot and waste falling on the top of the filter screen 10, preventing the steel shot and waste from accumulating on the top of the filter screen 10, facilitating the steel shot and waste to spread out on the top of the filter screen 10 for screening, and improving the screening effect;

[0027] Among them, in order to achieve the purpose of the fan blade 14 and the cam 18 rotating simultaneously, the following technical scheme is adopted in this device: The driving component includes two synchronous pulleys 15. The two synchronous pulleys 15 are respectively fixedly sleeved outside the transmission shaft 13 and the connecting shaft 17. A synchronous belt 16 is sleeved outside the two synchronous pulleys 15. The two synchronous pulleys 15 are drivingly connected through the synchronous belt 16. An avoidance groove is opened at the connection between the protective cover 5 and the waste material falling plate 9. The synchronous belt 16 passes through the avoidance groove. A motor 12 is arranged inside the protective cover 5. The motor 12 is fixedly connected with one side wall of the separation box 1. The output end of the motor 12 is fixedly connected with one end of the transmission shaft 13. The transmission shaft 13 passes through the cross support 6 and is connected with the cross support 6 through a bearing. Both ends of the connecting shaft 17 are connected with both side walls of the separation box 1 through bearings. The motor 12 is started. The motor 12 rotates to drive the transmission shaft 13 to rotate. The rotation of the transmission shaft 13 makes the connecting shaft 17 rotate through the cooperation of the synchronous pulley 15 and the synchronous belt 16. The rotation of the connecting shaft 17 drives the cam 18 to rotate;

[0028] Among them, in order to achieve the purpose of facilitating the separate discharge of steel shots and waste materials, the present device adopts the following technical solution: The waste material blanking plate 9 is fixedly arranged inside the separation box 1. One side of the waste material blanking plate 9 penetrates through the waste material opening 3 and extends outside the waste material opening 3. The steel shot blanking plate 19 penetrates through the steel shot opening 4 and is fixedly connected to the steel shot opening 4. The fan blade 14 rotates to blow air through the ventilation net 8 into the inside of the isolation cover 7, blowing out the light impurities in the steel shots and waste materials outside the isolation cover 7, and enabling the light impurities to slide out of the separation box 1 through the inclined surface of the waste material blanking plate 9 from the waste material opening 3. After preliminary cleaning, the steel shots and waste materials fall on the top of the filter screen 10 and are screened through the filter screen 10. The waste materials fall to the bottom of the separation box 1 after being screened by the filter screen 10. The steel shots slide onto the steel shot blanking plate 19 through the inclined surface and jitter of the filter screen 10 raised by the filter screen 10, and slide out of the separation box 1 through the inclined surface of the steel shot blanking plate 19 through the steel shot opening 4, achieving the purpose of separating the steel shots and waste materials;

[0029] Among them, in order to achieve the purpose of preventing the filter screen 10 from falling when jittering, the present device adopts the following technical solution: The two rotating shafts 11 are respectively connected to the two side walls of the separation box 1 through bearings. The filter screen 10 is connected to the bearings of the separation box 1 through the rotating shafts 11, enabling the filter screen 10 to be lifted and move through the rotating shafts 11 when jittering, so that the filter screen 10 is lifted at a certain angle, facilitating the steel shots on the top of the filter screen 10 to slide onto the steel shot blanking plate 19.

[0030] The usage process of the present utility model is as follows: When using the present utility model, the device is connected to a hook type shot blasting cleaning machine, so that the waste and steel shots after shot blasting can enter the inside of the separation box 1 through the feeding port 2. The motor 12 is connected to an external power source. When it is necessary to separate the steel shots and the waste, the waste and the steel shots enter the isolation cover 7 inside the separation box 1 through the feeding port 2. At the same time, the motor 12 is started. The rotation of the motor 12 causes the fan blade 14 to rotate through the transmission shaft 13. The rotation of the fan blade 14 causes the air to blow into the isolation cover 7 through the ventilation net 8, blowing out the light impurities in the steel shots and the waste outside the isolation cover 7, and causing the light impurities to slide out of the separation box 1 through the inclined surface of the waste blanking plate 9 from the waste outlet 3. The steel shots and the waste after preliminary cleaning fall on the top of the filter screen 10, achieving the purpose of reducing the screening amount of the filter screen 10, thereby preventing the filter screen 10 from being blocked due to a large screening amount during screening. At the same time, when the transmission shaft 13 rotates, the connection shaft 17 is caused to rotate through the cooperation of the synchronous pulley 15 and the synchronous belt 16. The rotation of the connection shaft 17 causes the filter screen 10 to be in a shaking state through the cam 18, shaking off the steel shots and the waste falling on the top of the filter screen 10, preventing the steel shots and the waste from accumulating on the top of the filter screen 10, facilitating the spreading of the steel shots and the waste on the top of the filter screen 10 for screening, and improving the screening effect. At the same time, after the waste is screened by the filter screen 10, it falls to the bottom of the separation box 1. The steel shots slide onto the steel shot blanking plate 19 through the inclined surface and shaking of the filter screen 10, and slide out of the separation box 1 through the inclined surface of the steel shot blanking plate 19 from the steel shot outlet 4, achieving the purpose of separating the steel shots and the waste.
