Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a screen frame installation structure for a vibrating screen. Background Technology

[0002] A vibrating screen is a mechanical device used for screening and classifying solid particulate materials. It uses a vibrator to make the screen mesh vibrate, causing the material to jump on the screen mesh, thus separating particles of different sizes.

[0003] In existing technologies, the installation of screens and screen beds is done by bolt fixing. The bolts are tightened from below, which is cumbersome due to the large number of bolts. Tightening the bolts from below usually requires operators to climb under the equipment to work, which not only makes the installation process complicated but also requires a high level of technical skills from the operators. In addition, due to the large number of bolts, the tightening and loosening process takes a long time, which leads to increased downtime of the equipment and affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mesh frame installation structure for a vibrating screen.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibrating screen frame installation structure, comprising: an installation mechanism, an auxiliary mechanism provided on the outside of the installation mechanism, the installation mechanism including an L-plate, a connecting rod provided on the inner wall of the L-plate, the inner wall of the L-plate being rotatably connected to the outer side of the connecting rod, a semi-circular block provided at the top of the connecting rod, the top of the connecting rod being fixedly connected to the center of the semi-circular block, a mesh frame body provided on the outer side of the semi-circular block, the outer side of the semi-circular block contacting the inner surface of the mesh frame body, a limiting cavity being formed in the inner wall of the mesh frame body, the inner surface of the limiting cavity being rotatably engaged with the outer side of the semi-circular block.

[0006] In a preferred embodiment, the auxiliary mechanism includes a crossbar, one end of which is provided with an outer ring, and one end of the crossbar is fixedly connected to one side of the outer ring. A lead screw is provided on the inner surface of the outer ring, and the inner surface of the outer ring is rotatably connected to the outer side of the lead screw. The other end of the crossbar is fixedly connected to the inner side of the sieve bed.

[0007] In a preferred embodiment, a gear is provided at the bottom end of the connecting rod, and the bottom end of the connecting rod is fixedly connected to the center of the gear. A toothed plate is provided on the outside of the gear, and the outside of the gear meshes with one side of the toothed plate.

[0008] In a preferred embodiment, one end of the toothed plate is slidably connected to the inner wall of the bottom side of the L-plate, and one end of the L-plate is fixedly connected to the inner side of the sieve bed.

[0009] In a preferred embodiment, a support plate is provided on the bottom side of the toothed plate, and one end of the support plate is fixedly connected to the bottom side of the toothed plate. A fixing block is provided on the bottom side of the support plate, and the top end of the fixing block is fixedly connected to the bottom side of the support plate.

[0010] In a preferred embodiment, the inner wall of the fixing block is threadedly connected to the outer side of the lead screw, a motor is provided at one end of the lead screw, the output end of the lead screw is fixedly connected to the output end of the motor, and the outer side of the motor is fixedly connected through the inner wall of the screen bed.

[0011] In a preferred embodiment, a positioning plate is provided at one end of the L-plate, and one end of the L-plate is fixedly connected to one end of the positioning plate.

[0012] In a preferred embodiment, one side of the positioning plate contacts one end of the wire mesh frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. Starting the motor causes the fixed block to move along with the pallet. The pallet has a toothed plate, which meshes with the gear on the connecting rod during the movement, causing the connecting rod to rotate. The length of the toothed plate allows the connecting rod to rotate 180 degrees. At this time, the semicircular block will rotate into the limiting cavity, thus completing the quick installation of the screen bed and the screen frame, eliminating the need for multiple bolts and manual tools in the traditional installation process.

[0015] 2. The outer ring installed on the lead screw can prevent the fixed block from going beyond the threaded part on the lead screw during the movement of the fixed block. Because the outer ring restricts the movement range of the fixed block, it keeps it within the threaded structure during operation, thereby accurately controlling the displacement of the fixed block, ensuring the normal operation of the equipment, preventing the fixed block from accidentally going beyond the threaded part, and avoiding mechanical impact or wear on the lead screw and its threads.

[0023] 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.

[0024] Example 1: As Figure 1 As shown in the figure, this utility model provides a technical solution: a screen frame installation structure for a vibrating screen, comprising: an installation mechanism 1, an auxiliary mechanism 2 provided on the outside of the installation mechanism 1, the installation mechanism 1 including an L-plate 12, a connecting rod 14 provided on the inner wall of the L-plate 12, the inner wall of the L-plate 12 being rotatably connected to the outer side of the connecting rod 14, a semi-circular block 112 provided at the top of the connecting rod 14, the top of the connecting rod 14 being fixedly connected to the center of the semi-circular block 112, a screen frame body 13 provided on the outer side of the semi-circular block 112, the outer side of the semi-circular block 112 contacting the inner surface of the screen frame body 13, a limiting cavity 113 provided on the inner wall of the screen frame body 13, the inner surface of the limiting cavity 113 being rotatably engaged with the outer side of the semi-circular block 112, a gear 15 provided at the bottom end of the connecting rod 14, the bottom end of the connecting rod 14 being fixedly connected to the center of the gear 15, and a toothed plate provided on the outer side of the gear 15. 16. The outer side of gear 15 meshes with one side of toothed plate 16. One top end of toothed plate 16 is slidably connected to the inner wall of bottom side of L plate 12. One end of L plate 12 is fixedly connected to the inner side of screen bed 11. A support plate 17 is provided on the bottom side of toothed plate 16. The bottom side of toothed plate 16 is fixedly connected to one end of support plate 17. A fixing block 18 is provided on the bottom side of support plate 17. The bottom side of support plate 17 is fixedly connected to the top of fixing block 18. The inner wall of fixing block 18 is threadedly connected to the outer side of lead screw 19. A motor 110 is provided on one end of lead screw 19. One end of lead screw 19 is fixedly connected to the output end of motor 110. The outer side of motor 110 is fixedly connected to the inner wall of screen bed 11. A positioning plate 111 is provided on one end of L plate 12. One end of L plate 12 is fixedly connected to one end of positioning plate 111. The side of one end of positioning plate 111 contacts one end of screen frame 13.

[0025] In this embodiment, the mesh frame installation structure of this type of vibrating screen is operated as follows: First, the mesh frame 13 is placed at the end of the L plate 12, and then the mesh frame 13 is pushed to cover the semicircular block 112. A limiting cavity 113 is opened inside the mesh frame 13. Therefore, by starting the motor 110, the fixing block 18 moves with the support plate 17. The support plate 17 has a toothed plate 16. During the movement, the toothed plate 16 will mesh with the gear 15 on the connecting rod 14, thereby causing the connecting rod 14 to rotate. The length of the toothed plate 16 is enough for the connecting rod 14 to rotate 180 degrees. At this time, the semicircular block 112 will rotate into the limiting cavity 113, thereby completing the quick installation of the screen bed 11 and the mesh frame 13. Therefore, this device can complete the installation work by starting the motor 110 to change the multiple connecting rods 14. It does not require multiple bolts to install the mesh frame 13, eliminating the need for multiple bolts and manual tools in the traditional installation process, simplifying the operation process and improving work efficiency.

[0026] Secondly, in order to ensure that the limiting cavity 113 and the semicircular block 112 can be accurately aligned, a positioning plate 111 is designed at one end of the L rod. When the mesh frame 13 is in contact with the positioning plate 111, it means that the limiting cavity 113 and the semicircular block 112 are aligned. The design of the positioning plate 111 allows the operator to directly observe and confirm whether the mesh frame 13 is accurately aligned with the limiting cavity 113 and the semicircular block 112, avoiding installation problems caused by positional deviations. It does not require complicated tools or experience, thus simplifying the operation steps.

[0027] Example 2: As Figure 1 As shown in the figure, the auxiliary mechanism 2 includes a crossbar 21. One end of the crossbar 21 is provided with an outer ring 22. One end of the crossbar 21 is fixedly connected to one side of the outer ring 22. A lead screw 19 is provided on the inner surface of the outer ring 22. The inner surface of the outer ring 22 is rotatably connected to the outer side of the lead screw 19. The other end of the crossbar 21 is fixedly connected to the inner side of the sieve bed 11.

[0028] In this embodiment, the outer ring 22 installed on the lead screw 19 can prevent the fixed block 18 from exceeding the threaded portion on the lead screw 19 during the movement of the fixed block 18. Since the outer ring 22 restricts the movement range of the fixed block 18, it keeps it within the threaded structure during operation, thereby precisely controlling the displacement of the fixed block 18, ensuring the normal operation of the equipment, preventing the fixed block 18 from accidentally exceeding the threaded portion, avoiding mechanical impact or wear on the lead screw 19 and its threads, and thus extending the service life of the equipment. The crossbar 21 installed on the outer ring 22 allows the user to fix the outer ring 22 to limit the fixed block 18 in a fixed position.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
