[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example 1
[0027] In the prior art, it is not easy to screen steel balls of different specifications at the same time, which results in a problem of reducing the screening speed of steel balls. This embodiment provides a steel ball screening machine, please refer to Figures 1-6 , capable of quickly and simultaneously screening steel balls of different sizes, improving the screening rate. The steel ball screening machine includes a screening box 2 mounted on top of a base frame 1. The screening box 2 is equipped with a screening mechanism 3 for screening steel balls of different sizes. A dust removal mechanism 4 is installed on top of the screening box 2 to absorb dust. The screening mechanism 3 can screen steel balls of different sizes, improving the screening rate. The dust removal mechanism 4 eliminates dust generated by the screening process, improving the screening environment.
[0028] In the process of screening steel balls, in order to be able to screen steel balls of different specifications at the same time and increase the screening rate of steel balls, the screening mechanism 3 includes a vibration motor 31 installed at the bottom end of the screening box 2, and a vibration spring 32 is connected to the connection between the base frame 1 and the screening box 2. A screen plate 33 is movably installed inside the screening box 2, and a plurality of groups of screen holes of different sizes are provided on the screen plate 33, which is convenient for screening steel balls of different sizes at the same time, thereby improving the screening efficiency. The screen plate 33 is fixed to the inside of the screening box 2 by a fixing bolt 34, which makes it easy to disassemble and assemble the screen plate 33, and can also be quickly replaced. A fixing bolt 34 is threaded on the screen plate 33, and a pull handle 35 is fixedly installed on the top of the screen plate 33. A buffer component 301 is provided at the discharge of the screening box 2 to reduce the falling pressure of the steel balls. Through the operation of the vibration motor 31, under the connection of the vibration spring 32, the screening box 2 is shaken, and the screen plate 33 is installed inside the screening box 2 through the fixing bolt 34, which is convenient for its replacement. The screen plate 33 screens steel balls of different specifications while shaking, thereby improving the screening rate of steel balls.
[0029] During the discharge of the steel balls, in order to reduce the pressure on the steel balls as they fall, the buffer assembly 301 includes a fixed block 36 mounted at the discharge of the screening box 2. A rotating block 37 is rotatably connected to the fixed block 36. A buffer plate 38 is fixedly mounted on the rotating block 37. The buffer plate 38 is arranged at an oblique angle at the discharge of the screening box 2 to facilitate the slow fall of the steel balls, thereby providing a buffering effect. The buffer plate 38 is connected to a buffer spring 39 connected to the discharge of the screening box 2. The buffer springs 39 are symmetrically distributed at the bottom of the buffer plate 38, thereby improving the buffering performance of the steel balls. When the steel balls fall, due to their own gravity and inertia, they fall into contact with the buffer plate 38. Since the buffer spring 39 has a certain buffering effect, the buffer plate 38 also has a certain buffering effect, thereby reducing the pressure generated by the falling steel balls and providing a protective effect.
[0030] Example 2
[0031] On the basis of Example 1, Figures 1-6 As shown, based on the current problem that it is not easy to screen steel balls of different specifications at the same time, the screening rate of steel balls is reduced. However, during the screening process of steel balls, the vibration will cause the dust generated to float in the box and the air, which is easy to affect the screening environment. Moreover, the dust floating in the air for a long time is easy to cause health harm to the workers. Therefore, the device is also provided with a structure that can eliminate the dust and debris generated by the screening of steel balls.
[0032] During the steel ball screening process, to absorb dust generated by vibration and prevent it from becoming airborne, a dust removal mechanism 4 includes a cover 41 movably mounted on top of the screening box 2. A dust collector 42 is mounted on top of the cover 41. A dust collection tube 43 is connected to the extraction end of the dust collector 42. The other end of the dust collection tube 43 is connected to a dust collection head 44 fixed to the interior of the cover 41. The screening box 2 is equipped with a locking assembly 401 that reinforces the cover 41. The operation of the dust collector 42, coupled to the dust collection tube 43, allows the two sets of dust collection heads 44 to simultaneously absorb dust from the interior of the screening box 2.
[0033] During the dust removal process, in order to be able to fit the screening box 2 tightly against the box cover 41, thereby improving the sealing performance of the entire device, the locking assembly 401 includes several groups of T-shaped steel plates 45 installed on the side of the screening box 2, and a pressure rod 46 is rotatably connected to the T-shaped steel plate 45. The side end of the pressure rod 46 is rotatably connected to a locking sleeve 47 connected to the box cover 41. The box cover 41 is closed on the top of the screening box 2, and the locking sleeve 47 is clamped on the box cover 41. By rotating the pressure rod 46, the locking sleeve 47 is firmly clamped on the box cover 41, thereby improving the sealing performance of the screening box 2.
[0034] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
