DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] In order to improve the screening efficiency of sand and gravel, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a first support frame 1, a second support frame 2, a screening funnel 3, an arch breaking component and a vibration component. The screening funnel 3 is arranged vertically above the second support frame 2 through a fixed frame 4. The vibration component includes a power unit arranged on the first support frame 1 and a vibration spring 5 arranged on the second frame and connected to the lower surface of the fixed frame 4. The arch breaking component is arranged in the screening funnel 3 to break the arch of the mined sand and gravel. The driving wheel 13 is driven to rotate by the power output end of the first motor 8, and the driven wheel 15 is driven to rotate by the transmission belt 14. The connecting rod 16 rotates, and the turntable 17 rotates accordingly, thereby driving the vibration plate 18 to float up and down. Under the elastic force of the vibration spring 5, the screening funnel 3 in the fixed frame 4 vibrates to screen the material. During the screening process, the sand and gravel to be screened are accumulated on the surface of the screen 19, driving the second motor 12. The power output end of the second motor 12 drives the rotating shaft 9 to rotate, and drives the arch breaking paddle 11 to rotate to break the arch of the sand and gravel. Arch breaking is performed while vibrating and screening, which can effectively improve the activity of the sand and gravel, avoid fine materials being mixed between coarse materials, and improve the screening efficiency of sand and gravel.
[0020] In order to break the sand and gravel, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the arch-breaking assembly includes a support plate 6 provided on the surface of the screening hopper 3. At the center of the upper surface of the support plate 6, a first motor 8 is provided through a mounting frame 7. The mounting frame 7 supports the first motor 8 to improve the stability of the first motor 8 during operation. The power output end of the first motor 8 is connected to a rotating shaft 9. The rotating shaft 9 passes through the support plate 6 and extends into the screening hopper 3 to be connected to a rotating plate 10. Arch-breaking paddles 11 are equidistantly arranged at equal intervals around the outer side of the rotating plate 10. By driving the rotating shaft 9 to rotate through the first motor 8, the rotating plate 10 drives the arch-breaking paddles 11 to rotate, so as to perform arch-breaking treatment on the sand and gravel placed on the screen 19. The arch-breaking paddles 11 are inclined, and the inclination degree is the same as that of the inner wall of the screening hopper 3, so there will be no collision. The power unit includes a second motor 12 provided on the upper surface of the first support frame 1. The power output end of the second motor 12 is connected to a driving wheel 13. The driving wheel 13 is connected to a driven wheel 15 through a transmission belt 14. The driven wheel 15 is fixed to the first support frame 1 by two vertical plates. The two vertical plates support the driven wheel 15 to improve the stability of the driven wheel 15. Driven by the second motor 12, the driving wheel 13 and the driven wheel 15 are directly driven by the transmission belt 14 to make the connecting rod 16 rotate. One end of the driven wheel 15 close to the second support frame 2 is connected to a connecting rod 16. The end of the connecting rod 16 away from the driven wheel 15 is connected to a turntable 17. The turntable 17 is arranged on a vibrating plate 18. The vibrating plate 18 is installed between the fixed frame 4 and the second support frame 2. As the connecting rod 16 rotates, the turntable 17 rotates on the surface of the vibrating plate 18, driving the vibrating plate 18 to form an up-and-down floating shake. Under the elastic force of the vibrating spring 5, the screening hopper 3 on the fixed frame 4 vibrates to complete the screening of the sand and gravel. A screen 19 is arranged in the screening hopper 3 to facilitate the screening treatment of the sand and gravel. On one side of the upper surface of the support plate 6, a feeding port is opened. A box door 20 is installed at the feeding port. A discharge port 21 is opened at the bottom of the screening hopper 3. By opening the box door 20, sand and gravel can be added into the screening hopper 3, and the screened sand and gravel are discharged from the discharge port 21.
[0021] During use, first, the power output end of the first motor 8 drives the driving wheel 13 to rotate. Through the transmission of the transmission belt 14, the driven wheel 15 is driven to rotate, so that the connecting rod 16 rotates, and the turntable 17 rotates accordingly, thereby driving the vibrating plate 18 to perform up-and-down floating. Under the elastic force of the vibrating spring 5, the screening hopper 3 in the fixed frame 4 vibrates for screening. And during the screening process, the sand and gravel to be screened accumulate on the surface of the screen 19. The second motor 12 is driven, and the power output end of the second motor 12 drives the rotating shaft 9 to rotate, driving the arch-breaking paddles 11 to rotate to perform arch-breaking treatment on the sand and gravel, and arch-breaking is carried out while vibrating and screening.
