[0043] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of the utility model.

[0044] The utility model discloses a kind of screening assembly 10, screening assembly 10 is used to screen quartz sand, can guarantee screening effect. Refer to Figures 1 to 6 The screening assembly 10 of the embodiment of the application is introduced below. Specifically, screening assembly 10 includes screen body 100 and drive assembly 200.

[0045] Referring to Figures 1 to 3 The screen body 100 is used for screening quartz sand. The screen body 100 comprises a drum frame 110 and a screen mesh 120. The drum frame 110 can support the screen mesh 120. Specifically, the screen mesh 120 is elastically connected to the drum frame 110 and arranged around the outer periphery of the drum frame 110. It can be understood that the screen mesh 120 can surround the entire outer periphery of the drum frame 110 to screen the quartz sand. It should be noted that after the quartz sand enters the screen body 100, the target size quartz sand can pass through the screen mesh 120 to separate from the screen body 100, and the large size quartz sand can be filtered in the screen body 100 for subsequent processing.

[0046] Referring to Figures 1 to 4 The driving assembly 200 is used for driving the screen body 100. Specifically, the driving assembly 200 comprises a first driving part and a second driving part 210. The first driving part is connected to the drum frame 110, and the second driving part 210 is connected to the screen mesh 120. It can be understood that the structure of the second driving part 210 can be different from that of the first driving part. The first driving part is used for driving the screen body 100 to rotate, and the second driving part 210 is used for driving the screen mesh 120 to vibrate relative to the drum frame 110. Specifically, the second driving part 210 can adopt a low-amplitude ultrahigh-frequency vibration motor.

[0047] The specific driving process of the driving assembly 200 will be introduced below. The first driving part can drive the screen body 100 to rotate around its circumference. It can be understood that in some embodiments, the first driving part can drive the screen body 100 to rotate in the clockwise direction. In other embodiments, the first driving part can also drive the screen body 100 to rotate in the counterclockwise direction. In other embodiments, the first driving part can also drive the screen body 100 to rotate alternately in the clockwise direction and the counterclockwise direction. When the screen body 100 rotates around its circumference, the second driving part 210 can drive the screen mesh 120 to vibrate relative to the drum frame 110. The specific vibration direction of the screen mesh 120 can be determined according to actual conditions.

[0048] In the technical scheme of the utility model, the screening assembly 10 includes a sieve body 100 and a driving assembly 200. The sieve body 100 includes a roller frame 110 and a screen 120, and the screen 120 is elastically connected to the roller frame 110 and arranged around the outer periphery of the roller frame 110. The driving assembly 200 includes a first driving part and a second driving part 210. The first driving part is connected to the roller frame 110, and the second driving part 210 is connected to the screen 120. In the prior art, a roller screen is used to screen the particle size of quartz sand. However, during the screening process, the quartz sand with a large particle size is easily stuck in the screen 120, so that part of the quartz sand with a target particle size in the sieve body 100 cannot normally pass through the screen 120 and separate from the sieve body 100, resulting in a small processing capacity of the roller screen and poor screening effect. The first driving part of the present scheme can drive the sieve body 100 to rotate around its circumference, and during the rotation of the sieve body 100 around its circumference, the second driving part 210 can drive the screen 120 to vibrate relative to the roller frame 110. The vibration can cause the large-particle-size quartz sand stuck or adhered to the screen 120 to fall off, that is, the present scheme can increase the processing capacity of the screening assembly 10, effectively improve the screening effect, and ensure the screening efficiency. Compared with the scheme in which the rotating screening structure and the vibrating screening structure are respectively arranged in two sieve bodies, the screening assembly 10 of the present scheme can simultaneously perform rotating screening and vibrating screening, can reduce the screening process, improve the screening efficiency and ensure the screening effect.
