[0002] Natural quartz sand refers to a non-metallic mineral mainly composed of silicon dioxide. It has wear resistance, high temperature resistance and chemical stability. It is widely used in the production of glass, ceramics, refractory materials and metallurgical silicon alloys. It can also be used as a filler to improve the properties of materials such as rubber and plastics. In the production and processing of natural quartz sand, it is necessary to use a dewatering screen to screen the washed natural quartz sand.

Each support leg is connected to the screen box via a damping spring. The screen box has a first discharge port on its left side and a second discharge port on its front side. A feed port is located on the upper right side of the screen box, communicating with the interior of the screen box. The bottom of the screen box is connected to the vibrating motor via a motor base. This invention effectively improves the sealing and wear resistance of the vibrating screen by providing side adhesive along the inner edge of the screen box side plate; the dual discharge port structure facilitates the diversion and conveying of quartz sand, avoiding blockages and effectively improving the conveying efficiency of quartz sand; the open structure design of this vibrating screen facilitates machine maintenance and timely cleaning of clogged clumps on the screen; it has the advantages of easy maintenance and high screening efficiency.
[0004] However, existing technologies rely solely on springs to support the screening equipment, resulting in poor stability. Furthermore, when screening natural quartz sand, the uniformity of the quartz sand feed is poor, leading to a tendency for accumulation. For example, the comparative patents listed above exhibit this problem.
[0005] To address these issues, we propose a natural quartz sand dewatering screen with a shock-absorbing support structure. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-8 The present invention provides the following technical solution:
[0034] To address the problems in existing technologies where screening equipment is supported only by springs, resulting in poor stability and uneven feeding of natural quartz sand, leading to accumulation, this solution provides a natural quartz sand dewatering screen with a shock-absorbing support structure. The screen comprises a screening box 1 and a screen 5 inserted into the lower end of the screening box 1. The moving feeding assembly consists of a feeding hopper 6 positioned above the screening box 1, connecting brackets 7 symmetrically positioned on the front and rear sides of the feeding hopper 6, a linear guide rail 8, and a driving mechanism 9. The moving feeding assembly evenly distributes the natural quartz sand onto the screen 5. Limiting components are provided on both the front and rear sides of the right end of the screen 5. These limiting components cause the screen 5 to disassemble at the lower end of the screening box 1. The limiting components also include fixing columns 11 fixing the front and rear sides of the right end of the screen 5, and fixing rods 12, fixing plates 13, and fixing caps 14 positioned on the front and rear sides of the right end of the screening box 1.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the screening box 1 is placed on the ground by a shock-absorbing support assembly. The shock-absorbing support assembly includes shock-absorbing rods 2 fixed to the front and rear sides of the screening box 1, shock-absorbing brackets 3 sleeved on the lower ends of the shock-absorbing rods 2, and shock-absorbing springs 4 disposed between the shock-absorbing rods 2 and the shock-absorbing brackets 3. The shock-absorbing rods 2 and the shock-absorbing brackets 3 are movably connected. Through the arrangement of the shock-absorbing rods 2, the shock-absorbing brackets 3, and the shock-absorbing springs 4, the screening box 1 and the screen 5 can be stably supported while also providing a certain buffering effect, improving stability during the screening process. A movable feeding assembly is also provided above the screening box 1. The cleaned natural quartz sand to be screened is added to the feed hopper 6. Then, through the setting of the drive mechanism 9, which has a servo motor for driving, a lead screw fixed to the output end of the servo motor and a movable block threaded to the outside of the lead screw, the movable block is connected to the front connecting bracket 7. The servo motor drives the lead screw to rotate, and the lead screw drives the movable block to move left and right. At the same time, the upper end of the movable block is connected to the front connecting bracket 7, which in turn drives the connecting bracket 7 to slide left and right between the linear guide rail 8, thereby driving the feed hopper 6 to move left and right above the screen 5.
[0036] Then, by holding the fixed handle 16, the baffle 15 is pulled to the right. The anti-detachment block prevents the baffle 15 from moving out of the lower end of the feed hopper 6. The baffle 15 loosens the blockage on the feed hopper 6. At this time, the natural quartz sand in the feed hopper 6 falls onto the screen 5 for screening. At the same time, the feed hopper 6 moves left and right at the upper end of the screen 5 to evenly distribute the natural quartz sand onto the screen 5, preventing accumulation on the screen 5, thereby improving the screening efficiency of the natural quartz sand. The vibrating motor 10 drives the screening box 1 to vibrate, further increasing the screening speed.
[0037] In addition, after screening is complete, turn off the power and combine Figure 6 , Figure 7 and Figure 8 As shown, limit components are provided on both the front and rear sides of the right end of the screening box 1. By rotating the fixed cap 14 connected to the outer surface of the fixed rod 12 and the fixed plate 13, the limit is provided. Then, the fixed plate 13 is pulled, and the fixed plate 13 slides between the fixed rod 12. The right end of the fixed plate 13 is disengaged from the fixed column 11, thereby releasing the limit between the screen 5 and the screening box 1. Then, the fixed column 11 is pulled to move the screen 5 out of the screening box 1, which facilitates the disassembly, cleaning and replacement of the screen 5.
[0038] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
