A bidirectional screw 5 is rotatably provided in the two moving chambers 2 on the same side, and one end of the bidirectional screw 5 passes through the mounting frame 1 and is fixedly connected to a turning handle 6, and the bidirectional screw 5 is threadedly connected to the moving seat 3. A limiting rod 7 is fixedly provided in the two moving chambers 2 on the other side, and the limiting rod 7 is slidably connected to the moving seat 3. A pressing block 8 is slidably connected to the fixing frame 4 through a track, and a screen 9 is movably provided between the pressing block 8 and the fixing frame 4. The lower end of the fixing frame 4 is threadedly connected to a first screw 10, and the first screw 10 is rotatably connected to the pressing block 8. Two first baffles 11 are symmetrically provided in the mounting frame 1;

[0032] The installation frame 1 is provided with a fixing chamber 12 , and an inserting plate 13 is movably provided on the fixing chamber 12 .

[0033] In this embodiment, when the screen 9 needs to be installed, the two ends of the screen 9 are placed in the fixing frame 4 respectively, and placed between the fixing frame 4 and the pressing block 8. The first screw 10 is rotated. Since the first screw 10 is threadedly connected to the fixing frame 4, the first screw 10 rotates and moves at the same time. The first screw 10 drives the pressing block 8 to move along the sliding connection with the fixing frame 4, so that the pressing block 8 cooperates with the fixing frame 4 to fix the two ends of the screen 9 to the two fixing frames 4. The handle 6 is turned, and the handle 6 drives the bidirectional screw 5 to rotate. The bidirectional screw 5 extending into the two fixed chambers 12 is provided with a threaded area in opposite directions, so that the two moving seats 3 drive the two fixing frames 4 to move away from each other. The fixing frame 4 drives the other moving seat 3 to move along the limit rod 7. At the same time, the fixing frame 4 pulls the screen 9, thereby tightening the screen 9. When the screen 9 is damaged, it can be removed and replaced using the opposite operation. The first baffle 11 blocks the gap between the mounting frame 1 and the fixing frame 4.

[0034] More specifically, the screen 9 can be installed by rotating the first screw 10, and the installed screen 9 can be tightened by rotating the handle 6. The screen 9 can be removed and replaced by the reverse operation. The granary is provided with mounting slots that match the mounting frame 1 and sockets that match the insert plate 13. The entire screen 9 can be installed inside the granary by inserting the mounting frame 1 into the mounting slots on both sides and inserting the insert plate 13 into the socket.

[0035] See also Figure 1-6 , as an implementation method for fixing the installation frame 1 to the granary: the lower end of the plug plate 13 extends into the movable chamber and is fixedly connected to a lifting plate 14, the lifting plate 14 is movably connected to the fixed chamber 12, and a plurality of springs 15 are fixedly connected between the lifting plate 14 and the fixed chamber 12, a push plate 16 is provided on one side of the lifting plate 14, one end of the push plate 16 extends to the outside of the fixed chamber 12, and a limiting groove 17 that cooperates with the push plate 16 is provided on one side of the installation frame 1.

[0036] Specifically, push the push plate 16, the push plate 16 moves along the limit slot 17, the push plate 16 drives the lifting plate 14 to move, the lifting plate 14 drives the plug plate 13 to move, so that the plug plate 13 is retracted, the spring 15 is compressed, and the granary is provided with a mounting groove that matches the mounting frame 1 and a socket that matches the plug plate 13. Insert the mounting frame 1 into the mounting grooves on both sides, loosen the push plate 16, and under the push of the spring 15, insert the plug plate 13 into the socket, so that the mounting frame 1 is fixed to the granary, and the entire screen 9 can be installed inside the granary.

[0037] See also Figure 1-6 As an embodiment of fixing both sides of the screen 9: two limit bars 18 and two support bars 19 are symmetrically provided in the installation frame 1, and a second screw 20 is threadedly connected to the support bar 19. The upper end of the second screw 20 passes through the support bar 19 and is rotatably connected to a pressing bar 21 connected to the installation frame (1) through a track. The fixing frame 4, the pressing block 8, the limit bar 18 and the pressing bar 21 are respectively provided with matching fixing teeth 22.

[0038] Specifically, the second screw 20 is rotated. Since the second screw 20 is threadedly connected to the support bar 19, the second screw 20 rotates and moves, and the second screw 20 drives the pressing bar 21 to move along the sliding connection with the mounting frame 1, so that the pressing bar 21 cooperates with the limiting bar 18 to clamp and fix the two sides of the screen 9. The provision of the fixing teeth 22 can increase the firmness of the fixing of the screen 9.

[0039] See also Figure 1-6 As an implementation method for shielding the mobile chamber 2 , four second shielding plates 23 are symmetrically provided on one side of the fixing frame 4 .

[0040] Specifically, when the fixing frame 4 moves, the fixing frame 4 drives the second shielding plate 23 to move to shield the fixing chamber 12 .

[0041] In summary, when the overall equipment is in use:

[0042] When the screen 9 needs to be installed, the two ends of the screen 9 are placed in the fixing frame 4 respectively, and placed between the fixing frame 4 and the pressing block 8, and the first screw 10 is rotated. Since the first screw 10 is threadedly connected to the fixing frame 4, the first screw 10 rotates and moves, and the first screw 10 drives the pressing block 8 to move along the sliding connection with the fixing frame 4, so that the pressing block 8 cooperates with the fixing frame 4 to fix the two ends of the screen 9 to the two fixing frames 4. The fixing teeth 22 can increase the firmness of the fixing of the screen 9. The turning handle 6 is turned, and the turning handle 6 drives the bidirectional screw 5 to rotate. The bidirectional screw 5 extending into the two fixing chambers 12 is provided with a threaded area in opposite directions, so that the two moving seats 3 drive the two fixing frames 4 to move away from each other, and the fixing frame 4 drives the other moving seat 3 to move along the limit rod 7. At the same time, the fixing frame 4 pulls the screen 9, thereby tightening the screen 9. The first shielding plate 11 blocks the gap between the installation frame 1 and the fixing frame 4. When the fixing frame 4 moves, the fixing frame 4 drives the second shielding plate 23 to move to shield the fixing chamber 12 .

[0043] When the screen 9 needs to be fixed on both sides, the second screw 20 is rotated. Since the second screw 20 is threadedly connected to the support bar 19, the second screw 20 rotates and moves simultaneously. The second screw 20 drives the pressing bar 21 along the sliding connection with the mounting frame 1, so that the pressing bar 21 cooperates with the limiting bar 18 to clamp and fix the two sides of the screen 9. The provision of the fixing teeth 22 can increase the firmness of the fixing of the screen 9. If the screen 9 is damaged, it can be removed and replaced using the reverse operation.

[0044] When the mounting frame 1 and the screen 9 need to be installed in the silo, the push plate 16 is pushed, and the push plate 16 moves along the limit slot 17. The push plate 16 drives the lifting plate 14 to move, and the lifting plate 14 drives the plug plate 13 to move, so that the plug plate 13 is retracted and the spring 15 is compressed. The granary is provided with a mounting slot that matches the mounting frame 1 and a socket that matches the plug plate 13. Insert the mounting frame 1 into the mounting slots on both sides, loosen the push plate 16, and under the push of the spring 15, insert the plug plate 13 into the socket, so that the mounting frame 1 is fixed to the granary, and the entire screen 9 can be installed inside the granary.

[0045] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
