[0001] This utility model relates to the field of roller screens with easily replaceable screen shafts, and in particular to a roller screen with easily replaceable screen shafts. Background Technology

[0002] The raw materials of sand and gravel plants are all mixtures of mud and stone. If they are not processed, the crushed materials will be of poor quality and affect their use. In the past, sand and gravel plants used sand washing machines and stone washing machines, which not only greatly increased costs, but were also environmentally unfriendly and wasted water resources. Therefore, a mud and stone separator, also known as a roller screen, was developed. It can separate mud and stone mixtures without water, thereby improving the quality of sand and gravel.

[0003] For example, the utility model disclosed in authorization announcement number CN217774710U is a roller screen that facilitates the replacement of the screen shaft. By setting a bracket and comb teeth, the comb teeth can scrape off the excessive mud between the two screen plates on the screen shaft during long-term operation, so that the roller screen can maintain a good screening effect. However, existing roller screens are difficult to replace the screen shaft according to actual usage needs. Not only is it necessary to use auxiliary tools to disassemble the screen shaft, but it also requires the assistance of multiple people to replace it, which is time-consuming, labor-intensive, and not very practical. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a roller screen with an easy-to-replace screen shaft. It solves the problem that existing roller screens, by setting brackets and comb teeth, allow the comb teeth to scrape away excessively thick mud between the two screen plates on the screen shaft during long-term operation, thus maintaining a good screening effect. However, existing roller screens are difficult to replace the screen shaft according to actual usage needs. Not only is it necessary to use auxiliary tools to disassemble the screen shaft, but it also requires the assistance of multiple people to replace it, which is time-consuming, labor-intensive, and impractical.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a roller screen with an easy-to-replace screen shaft, comprising a machine body, a support leg fixedly installed at the bottom corner of the machine body, a motor installed on the side wall of the machine body, and a rotating seat connected to the output end of the motor, a cross groove opened on the inner side of the rotating seat, a positioning hole opened on the outer surface of the rotating seat, a shaft distributed on the inner side of the machine body, and a connecting seat fixedly installed at one end of the shaft, a guide structure opened on the inner side of the connecting seat, a first spring distributed on the inner side of the connecting seat, and a snap-fit ​​seat fixedly connected to the other end of the first spring, an annular snap ring provided on the side wall of the snap-fit ​​seat, and a guide block provided on the outer surface of the annular snap ring, a cross block provided at the end of the snap-fit ​​seat away from the annular snap ring, and a second spring fixedly connected to the inner cavity of the cross block, a positioning rod fixedly connected to the other end of the second spring, and an auxiliary sliding plate sleeved on the outer side of one end of the positioning rod.

[0006] As a preferred technical solution of this utility model, the guide structure includes an annular groove, a guide groove, and a recess. The annular groove is provided on the periphery of the connecting seat, the guide groove is provided on the inner side wall of the connecting seat, and the recess is distributed on the inner side of the annular groove.

[0007] As a preferred embodiment of this utility model, the rotating seats are equidistantly distributed on the inner sidewall of the machine body, and the cross groove and the rotating seats form an integrated structure.

[0008] As a preferred embodiment of this utility model, the guide grooves are equidistantly distributed along the center point of the annular slot, and the guide grooves and the connecting seat form an integrated structure.

[0009] As a preferred embodiment of this utility model, the first spring is equidistantly distributed along the center point of the snap-fit ​​seat, and the snap-fit ​​seat is slidably connected to the connecting seat through the first spring.

[0010] In a preferred embodiment of this invention, the positioning rod is slidably connected to the cross block via the second spring, and the positioning rod is symmetrically distributed pressing against the vertical center line of the cross block.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. With the combination of the connecting seat, snap-fit ​​seat, and cross block, the subsequent quick disassembly and installation between the shaft and the machine body can be easily achieved, thus facilitating the replacement of the shaft. It is convenient, quick, and more practical, eliminating the need for auxiliary tools to disassemble the shaft. When the snap-fit ​​seat drives the cross block to engage with the rotating seat, the positioning rod is inserted into the inside of the positioning hole, thereby achieving quick installation between the shaft and the machine body. It is convenient and quick.

[0013] 2. By combining the first spring, the annular retaining ring, and the guide block, the stability of the subsequent lateral movement of the locking seat can be improved, preventing positional displacement when the cross block engages with the cross groove, which could lead to deviations in the installation of the subsequent shaft and cause unnecessary trouble. The reverse force generated by the deformation of the first spring will push the locking seat, and then the locking seat will drive the annular retaining ring and the guide block to slide along the annular retaining groove and the guide groove, respectively, thereby improving the stability of the locking seat during movement.

A support leg 2 is fixedly installed at the bottom corner of the machine body 1. A motor 3 is installed on the side wall of the machine body 1, and the output end of the motor 3 is connected to a rotating seat 4. A cross groove 5 is opened on the inner side of the rotating seat 4, and a positioning hole 6 is opened on the outer surface of the rotating seat 4. A shaft 7 is distributed on the inner side of the machine body 1, and a connecting seat 8 is fixedly installed at one end of the shaft 7. A guide structure is opened on the inner side of the connecting seat 8. A first spring 12 is distributed on the inner side of the connecting seat 8, and a snap-fit ​​seat 13 is fixedly connected to the other end of the first spring 12. An annular snap ring 14 is provided on the side wall of the snap-fit ​​seat 13, and a guide block 15 is provided on the outer surface of the annular snap ring 14. A cross block 16 is provided at the end of the snap-fit ​​seat 13 away from the annular snap ring 14, and a second spring 17 is fixedly connected to the inner cavity of the cross block 16. A positioning rod 18 is fixedly connected to the other end of the second spring 17, and an auxiliary sliding plate 19 is sleeved on the outer side of one end of the positioning rod 18.

[0022] In use, first install the shaft 7 between the shaft body 7 and the rotating seat 4. After multiple shaft bodies 7 are installed, the rotating seat 4 is rotated by the operation of the motor 3, thereby driving the shaft body 7 to rotate, which facilitates normal use in the future.

[0023] As a further implementation of this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a motor 3 is installed on the side wall of the machine body 1, and the output end of the motor 3 is connected to a rotating seat 4. The rotating seats 4 are equidistantly distributed on the inner side wall of the machine body 1, and the cross grooves 5 and the rotating seats 4 form an integrated structure. The inner side of the rotating seats 4 has cross grooves 5, and the outer surface of the rotating seats 4 has positioning holes 6. The inner side of the machine body 1 has shafts 7, and one end of the shafts 7 is fixedly installed with a connecting seat 8. The outer periphery of the connecting seat 8 has an annular groove 9, and the inner side wall of the connecting seat 8 has a guide groove 10. The guide grooves 10 are equidistantly distributed along the center point of the annular groove 9, and the guide grooves 10 and the connecting seat 8 form an integrated structure. The inner side of the annular groove 9 has grooves 11. The annular groove 9, the guide groove 10, and the grooves 11 form a guide structure, and the guide structure is located on the inner side of the connecting seat 8. A first spring 12 is distributed on the inner side of the connector 8, and the other end of the first spring 12 is fixedly connected to a snap-fit ​​seat 13. The first spring 12 is equidistantly distributed along the center point of the snap-fit ​​seat 13, and the snap-fit ​​seat 13 is slidably connected to the connector 8 through the first spring 12. An annular snap ring 14 is provided on the side wall of the snap-fit ​​seat 13, and a guide block 15 is provided on the outer surface of the annular snap ring 14. A cross block 16 is provided at the end of the snap-fit ​​seat 13 away from the annular snap ring 14, and a second spring 17 is fixedly connected to the inner cavity of the cross block 16. A positioning rod 18 is fixedly connected to the other end of the second spring 17, and an auxiliary sliding plate 19 is sleeved on the outer side of one end of the positioning rod 18. The positioning rod 18 is slidably connected to the cross block 16 through the second spring 17, and the positioning rod 18 is symmetrically distributed along the vertical center line of the cross block 16.

[0024] When it is necessary to disassemble the shaft 7 from the body 1, firstly, the positioning rod 18 is squeezed, and then the positioning rod 18 disengages from the inside of the positioning hole 6 and retracts into the inner cavity of the cross block 16. At the same time, when the positioning rod 18 moves laterally, it squeezes the second spring 17, causing the second spring 17 to deform. The reverse force generated by its deformation facilitates the subsequent lateral reset of the auxiliary positioning rod 18. The auxiliary sliding plate 19 is set to improve the stability of the positioning rod 18 during lateral movement. Then, when the positioning rod 18 is completely disengaged from the inside of the positioning hole 6, the locking seat 13 is moved laterally, and then the locking seat 13 drives the cross block 16 to move laterally. This causes the cross block 16 to disengage from the cross groove 5, thereby separating the locking seat 13 from the rotating seat 4. Simultaneously, the transverse movement of the locking seat 13 causes the annular retaining ring 14 to slide along the annular retaining groove 9, while the guide block 15 moves synchronously along the guide groove 10. This improves the stability of the locking seat 13 during transverse movement. The locking seat 13 also compresses the first spring 12, causing it to deform. This facilitates the subsequent transverse reset of the locking seat 13 using the reverse force generated by the deformation of the first spring 12, making it easier to reinstall the shaft 7. The overall structure is convenient, quick, and highly practical.
