[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0020] 1. This utility model, by setting up a screening component, allows the drive component to rotate the cam during screening. The cam then drives the support plate to slide up and down continuously, causing the support plate to vibrate the coarse and fine screen plates. This enables multi-stage screening of quartz sand. At the same time, because the coarse and fine screen plates are arranged at an angle, the quartz sand on the coarse and fine screen plates gradually rolls into the discharge hopper and is quickly discharged from the discharge hopper, improving screening efficiency.

[0021] 2. By setting up protective baffles, this utility model can shield and protect both sides of the support plate, preventing quartz sand from entering the area between the two protective baffles, thereby preventing the cam, drive assembly, support rod, first spring and second spring from being affected by quartz sand.

[0031] This utility model provides a technical solution:

[0032] Please see Figures 1-4A multi-stage fracturing quartz sand screening machine includes a screening box 1, a feeding assembly 2, and a screening assembly 3. The feeding assembly 2 is located above the screening box 1 and includes a feeding hopper 21 fixedly installed on the top of the screening box 1. A diverting block 22 is provided in the middle of the feeding hopper 21, and feeding ports 23 are opened on both sides of the bottom of the feeding hopper 21 located on the diverting block 22. By setting the feeding assembly 2, quartz sand can be added into the feeding hopper 21 during screening. Under the diversion action of the diverting block 22, the quartz sand enters the screening box 1 from the two feeding ports 23 respectively. When the quartz sand is fed into the screening box 1, the quartz sand on both sides is made as relatively uniform as possible.

[0033] Reference Figures 2-4 The screening assembly 3 is installed inside the screening box 1. The screening assembly 3 includes a support plate 31 slidably installed in the middle of the screening box 1. A coarse screen plate 32 and a fine screen plate 33 are fixedly installed on both sides of the support plate 31. The coarse screen plate 32 and the fine screen plate 33 are arranged inclined from top to bottom. A cam 34 is rotatably installed inside the screening box 1 below the support plate 31. The support plate 31 abuts against the cam 34. A drive assembly 35 for driving the cam 34 to rotate is provided at the bottom of the screening box 1. A discharge port 11 is opened on both sides of the screening box 1. A discharge hopper 12 is fixedly installed on the screening box 1 near the discharge port 11. Two discharge hoppers 12 are arranged at an inclination in opposite directions. The bottom of the screening box 1 is provided with a discharge port 13. By setting the screening component 3, during screening, the drive component 35 can be activated to drive the cam 34 to rotate, so that the cam 34 drives the support plate 31 to slide up and down continuously, so that the support plate 31 drives the coarse screen plate 32 and the fine screen plate 33 to vibrate up and down, thereby enabling multi-stage screening of quartz sand. At the same time, since the coarse screen plate 32 and the fine screen plate 33 are arranged at an inclination, the quartz sand on the coarse screen plate 32 and the fine screen plate 33 will gradually roll into the discharge hopper 12 and be quickly discharged from the discharge hopper 12, thereby improving the screening efficiency.

[0034] Specifically, the drive assembly 35 includes a motor 351 fixedly installed at the bottom of the screening box 1. A drive wheel 352 is fixedly installed at the output end of the motor 351. A driven wheel 353 is coaxially connected to one side of the cam 34. The drive wheel 352 and the driven wheel 353 are linked by a belt. By setting the drive assembly 35, the motor 351 can be started to drive the drive wheel 352 to rotate, which in turn drives the driven wheel 353 to rotate, and the driven wheel 353 drives the cam 34 to rotate.

[0035] Furthermore, support rods 36 are slidably installed on both sides of the support plate 31. The support rods 36 are fixedly installed inside the screening box 1. By setting the support rods 36, the support plate 31 can be guided and supported, making the support plate 31 more stable when sliding up and down.

[0036] Furthermore, a first spring 37 is sleeved on the upper end of the support rod 36, and the lower end of the first spring 37 abuts against the upper end of the support plate 31. By setting the first spring 37, the top of the support plate 31 can be elastically supported. When the cam 34 abuts against the support plate 31 and rises, the first spring 37 will be compressed. When the support plate 31 descends, it can elastically reset the support plate 31, so that the support plate 31 can quickly slide down and reset.

[0037] Furthermore, a second spring 38 is sleeved on the lower end of the support rod 36, and the upper end of the second spring 38 abuts against the lower end of the support plate 31. By setting the second spring 38, the bottom of the support plate 31 can be elastically supported. When the support plate 31 descends, it can buffer the support plate 31 and avoid a large impact on the screening box 1 when the support plate 31 descends, thereby helping to extend the service life of the equipment.

[0038] Furthermore, protective baffles 14 are fixedly connected to both sides of the support plate 31 inside the screening box 1. By setting the protective baffles 14, the two sides of the support plate 31 can be shielded and protected, which can prevent quartz sand from entering the area between the two protective baffles 14, thereby preventing the cam 34, drive assembly 35, support rod 36, first spring 37 and second spring 38 from being affected by quartz sand.

[0039] Furthermore, a door 15 is hinged to one side of the screening box 1. The door 15 is fixed to the screening box 1 by a latch 16. By setting the door 15, after screening is completed, the latch 16 can be loosened to open the door 15, which facilitates the maintenance of the interior of the screening box 1.

[0040] In practical use, the working principle of this utility model is as follows:

[0041] First, during screening, quartz sand can be added into the feed hopper 21. Under the diversion action of the diverting block 22, the quartz sand enters the screening box 1 from the two feed ports 23 respectively. When the quartz sand is fed into the screening box 1, the quartz sand on both sides is made to be as relatively uniform as possible.

[0042] During the feeding process, the motor 351 can be started to drive the drive wheel 352 to rotate, which in turn drives the driven wheel 353 to rotate. The driven wheel 353 then drives the cam 34 to rotate, which in turn drives the support plate 31 to slide up and down continuously. This causes the support plate 31 to vibrate the coarse screen plate 32 and the fine screen plate 33, thus enabling multi-stage screening of the quartz sand. At the same time, since the coarse screen plate 32 and the fine screen plate 33 are arranged at an incline, the quartz sand on the coarse screen plate 32 and the fine screen plate 33 will gradually roll into the discharge hopper 12 and be quickly discharged from the discharge hopper 12, thereby improving the screening efficiency.

[0043] To prevent the cam 34, drive assembly 35, support rod 36, first spring 37 and second spring 38 from being affected by quartz sand, a protective baffle 14 is provided to shield and protect both sides of the support plate 31, thus preventing quartz sand from entering the area between the two protective baffles 14.

[0044] In summary, this multi-stage fracturing quartz sand screening machine, by setting screening component 3, can perform multi-stage screening of quartz sand, avoiding the accumulation of quartz sand in the device and improving screening efficiency.

[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
