Technical Field
[0001] This utility model belongs to the field of steel ball screening, specifically relating to a wear-resistant steel ball screening device. Background Technology
[0002] A steel ball screening device is a device used to separate and screen steel balls of different sizes. It is commonly used in industrial production, especially in the quality control stage of steel ball manufacturing and use, to ensure that the size and quality of the steel balls meet the requirements.
[0003] Currently, most existing steel ball screening devices use vibrating screening to screen wear-resistant steel balls of different specifications or shapes. However, traditional vibrating screening structures generate large vibration amplitudes during use, which can easily cause the entire screening equipment to shake, resulting in poor stability during use, easy tipping, and significant noise.
[0004] Therefore, in response to the problem of poor stability and easy tipping of existing steel ball screening equipment, a wear-resistant steel ball screening device was developed. By adding multiple buffer structures to the screening device, the screening box on it can be vibration damped in the left and right and up and down directions, thereby improving the stability of the screening equipment during use and preventing it from tipping over.

Detailed Implementation
[0023] A steel ball screening device is a piece of equipment used to separate and screen steel balls of different sizes. It is commonly used in industrial production, especially in quality control during the manufacturing and use of steel balls, to ensure that the size and quality of the steel balls meet requirements. This device utilizes the function of a screen or separator to sieve steel balls through screens of different apertures, thereby separating steel balls of different sizes, shapes, and qualities.
[0024] Common types of steel ball screening devices:
[0025] Vibrating screen: It uses vibration to separate steel balls on the screen surface. Different screen apertures can effectively separate steel balls of different sizes. Vibrating screens are usually used for large-scale screening, are highly efficient and suitable for continuous operation.
[0026] Rotary screener: It uses a rotating screen cylinder or screen to separate steel balls of different sizes by gravity. It is suitable for separating steel balls of different sizes. The working principle is simple and it is suitable for small and medium-sized production lines.
[0027] Airflow separator: It uses high-pressure airflow to blow steel balls, so that steel balls of different weights and sizes are subjected to different airflow resistances, thereby achieving the purpose of sorting. It is usually used to screen small steel balls or lighter particles.
[0028] Working principle:
[0029] Steel ball screening devices generally achieve screening through the following methods:
[0030] Size sorting: Steel balls of different sizes are separated by using sieves with different apertures.
[0031] Gravity sorting: Relying on the weight difference of steel balls, heavier steel balls sink and lighter steel balls float, thereby achieving sorting.
[0032] Vibration and rotation: By vibrating or rotating, steel balls are made to move sufficiently on the screen surface, and sorting is carried out by means of the screen aperture.
[0033] Application areas:
[0034] Steel ball manufacturing industry: Ensure that steel balls that meet specifications are produced.
[0035] Machinery Industry: In certain mechanical equipment, the selection of steel balls is crucial, especially in the fields of rolling bearings and conveying equipment.
[0036] Mining, metallurgy and other industries: used for sorting ores or metal particles.
[0037] Steel ball screening devices can be customized to meet the accuracy and efficiency requirements of different production processes.
[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0039] Please see Figures 1-6 This utility model provides an embodiment of a wear-resistant steel ball screening device, including a base 1, a screening box 2, a feed hopper 3, a screening plate 4, and a vibrating motor 5. It also includes a first buffer pad 6, a second buffer pad 7, a third buffer pad 9, a limiting rod 10, and a sliding sleeve 14. An inclined discharge chute 11 is provided at the upper end of the base 1. The upper end of the base 1 is respectively fixed with symmetrically distributed first buffer pads 6 and second buffer pads 7. The first buffer pads 6 and second buffer pads 7 are distributed on the left and right sides of the discharge chute 11, and the two sets of second buffer pads 7 are located on two separate sides. Between the first buffer pads 6, two sets of first grooves 8 are symmetrically distributed on the upper edge of the base 1. The inner wall of the first groove 8 is fixedly connected to a limiting rod 10. The left and right ends of the limiting rod 10 are fixedly connected to third buffer pads 9. The four corner edges of the lower end of the screening box 2 are fixedly connected to sliding sleeves 14. The inner wall of the sliding sleeve 14 is in contact with the outer wall of the limiting rod 10. The outer wall of the sliding sleeve 14 is in contact with the first groove 8. The lower end of the screening box 2 is provided with second grooves 13 symmetrically distributed on the left and right. The second grooves 13 are adapted to the second buffer pads 7.
[0040] The first buffer pad 6 can dampen the vibration motor 5, and the third buffer pad 9 can dampen the bottom of the screening box 2. The sliding sleeve 14 can assist the high-frequency vibrating screening box 2 to move left and right along the outer wall of the limiting rod 10. The second buffer pad 7 can dampen the left and right ends of the sliding sleeve 14 to dampen the vibration of the screening box 2 driven by the vibration motor 5 in the left and right and up and down directions, so as to improve the stability of the screening equipment during use and prevent it from tipping over.
[0041] Please see Figures 3-5In this embodiment, a vibration motor 5 is installed on the first buffer pad 6. The output end of the vibration motor 5 is connected to the left and right ends of the screening box 2. During use, the vibration motor 5 can drive the screening box 2 to vibrate at a high frequency, thereby driving the screening plate 4 inside to screen the wear-resistant steel balls. A third groove 16 is provided through the lower end of the screening box 2. A feeding hopper 15 is installed in the third groove 16. During use, the feeding hopper 15 can be used to centrally feed and guide the screened wear-resistant steel balls to prevent them from splashing everywhere. A feeding hopper 3 is installed at the upper end of the screening box 2. The feeding hopper 15 is located at the center of the inner wall of the discharge groove 11. During use, the feeding hopper 3 makes it easy for the user to pour the wear-resistant steel balls into the screening box 2 for screening. The lower end of the screening box 2 is adjustable to the upper end of the base 1. The base 1 is in the shape of a square platform. During use, the square platform-shaped base 1 can provide better support for the screening box 2.
[0042] Please see Figures 4-6 In this embodiment, the screening plate 4 is installed at both ends of the screening box 2 by fixing bolts 17. The left and right ends of the screening plate 4 are provided with handles. During use, the user can easily replace or adjust the screening plate 4 in the through hole 12 by using the handles on the screening plate 4. The left and right ends of the screening box 2 are provided with through holes 12 that are symmetrically distributed vertically. The screening plate 4 is provided in the through hole 12. During use, the user can easily replace the screening plate 4 with different mesh sizes as needed by using the through hole 12.
[0043] When in use, the wear-resistant steel balls to be screened are put into the feed hopper 3, and the two sets of vibration motors 5 are started. The vibration motors 5 drive the screening box 2 to vibrate at high frequency to vibrate and screen the wear-resistant steel balls that have entered the screening box 2 and fallen onto the screening plate 4.
[0044] Next, the wear-resistant steel balls after screening will fall down the inner wall of the feed hopper 15 into the discharge chute 11, and roll outward along the slope of the inner wall of the discharge chute 11.
[0045] During screening, the first buffer pad 6 dampens the vibration motor 5, while the third buffer pad 9 dampens the bottom of the screening box 2. The sliding sleeve 14 assists the high-frequency vibrating screening box 2 to move left and right along the outer wall of the limiting rod 10. The second buffer pad 7 dampens the left and right ends of the sliding sleeve 14 to dampen the high-frequency vibrating screening box 2 in the left, right and up and down directions.
[0046] Through the above steps, the first buffer pad 6 can dampen the vibration motor 5, and the third buffer pad 9 can dampen the bottom of the screening box 2. The sliding sleeve 14 can assist the high-frequency vibrating screening box 2 to move left and right along the outer wall of the limiting rod 10. The second buffer pad 7 can dampen the left and right ends of the sliding sleeve 14 to dampen the vibration of the screening box 2 driven by the vibration motor 5 in the left and right and up and down directions, thereby improving the stability of the screening equipment during use and preventing it from tipping over. This solves the problem of poor stability and easy tipping of the existing steel ball screening equipment.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
