[0026] 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.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a quick-change screen frame structure for a quartz sand gyratory screen, comprising a screen frame body 1, a screen 2, a fixed frame 3, a first support spring 4, a fixed bracket 5, a second support spring 6, a mounting bracket 7, a mounting block 8, a first connecting handle 9, a fixed block 10, a stop block 11, a connecting rod 12, a return spring 13, and a second connecting handle 14.

[0028] First, as attached Figure 1 As shown, the screen frame body 1 is installed on the gyratory screen. The quartz sand to be screened is poured into the screen frame body 1, and the gyratory screen drives the screen frame body 1 to vibrate. The screen 2 is connected to the inside of the screen frame body 1 by a slot. The outside of the screen 2 is provided with a limiting mechanism to prevent the screen 2 from shaking, so that the screen 2 is fixed inside the screen frame body 1. The screen 2 screens the quartz sand. When the screen 2 needs to be disassembled for cleaning, a quick-operation adjustment mechanism is provided on the front side of the limiting mechanism. The screen 2 can be disassembled by adjusting the mechanism.

[0029] As attached Figure 1 and attached Figure 5As shown, the stop block 11 is tightly fitted to the front side of the fixed block 10, and the stop block 11 limits the left and right movement of the fixed block 10. The adjustment mechanism includes a first connecting handle 9, a fixed block 10, a stop block 11, a connecting rod 12, a return spring 13, and a second connecting handle 14. The second connecting handle 14 is installed on the front side of the stop block 11. Pulling the second connecting handle 14 causes the stop block 11 and the second connecting handle 14 to rotate and connect. The second connecting handle 14 drives the stop block 11 to swing. The stop blocks 11 are symmetrically arranged on the second connecting handle 14 to quickly adjust the position of the two stop blocks 11. The stop blocks 11 are rotatably connected to the grid frame body 1 through the connecting rod 12 and the return spring 13. Adjusting the angle of the stop blocks 11, the connecting rod 12 is fixed above the rear side of the stop block 11. The stop block 11 drives the connecting rod 12 to rotate. The return spring 13 is wound around the outside of the connecting rod 12. The connecting rod 12 compresses the return spring 13, causing the stop block 11 to disengage from the fixed block 10, so that the first connecting handle 9 can be pulled outward.

[0030] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the limiting mechanism includes a fixed frame 5, a second support spring 6, a mounting frame 7, and a mounting block 8. Pulling the first connecting handle 9 outward causes the mounting block 8, which is fixed at its rear end, to move, disengaging the mounting block 8 from the mounting frame 7. The mounting frame 7 is slidably connected to the fixed frame 5 via the second support spring 6. The second support spring 6 is fixed in the middle of the inner side of the fixed frame 5, and the mounting frame 7 is fixed in the inner end of the second support spring 6. When the mounting block 8 disengages from the mounting frame 7, the second support spring 6 pulls the mounting frame 7 outward. The mounting frame 7 and the mounting block 8 are connected by a slot, and the mounting block 8 limits the left and right movement of the mounting frame 7, ensuring the stability of the mounting frame 7, allowing the screen 2 to be disassembled.

[0031] When it is necessary to install the screen 2, push the first connecting handle 9 backward. The first connecting handle 9 drives the mounting block 8 to move. The cross-section of the mounting block 8 is a triangular structure. The mounting block 8 pushes the mounting frame 7, causing the mounting frame 7 to move inward and connect with the screen 2 and the screen frame body 1 through the slot, thus fixing the screen 2 inside the screen frame body 1. The fixing frame 5 is fixed on the left and right sides of the screen 2 to ensure stability.

[0032] As attached Figure 2 As shown, the screen 2 is connected to the slot inside the frame body 1, and the fixing frame 3 is fixed to the inside of the frame body 1, so that the screen 2 and the fixing frame 3 fit tightly together. The fixing frame 3 supports the screen 2. The first support spring 4 is installed inside the fixing frame 3. The screen 2 compresses the first support spring 4. When the mounting bracket 7 is disengaged from the slot of the screen 2, the elastic action of the first support spring 4 pushes the screen 2 to rise. The first support spring 4 is evenly distributed in the fixing frame 3, which allows the screen 2 to be quickly disassembled.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
