Description

Technical Field

[0001] This utility model relates to the field of vibrating screens, and in particular to a multi-stage automatic vibrating screen. Background Technology

[0002] A vibrating screen is one of the tools used for screening materials.

[0003] When the two sets of eccentric blocks on the vibrating screen rotate simultaneously, since the mass and eccentricity of the two sets of eccentric blocks are equal, the centrifugal forces they experience are equal in magnitude and the direction of rotation is the same. At each instant, the centrifugal forces generated by the two sets of eccentric blocks always superimpose in all directions, causing the screen box to vibrate periodically along the direction of the excitation force. The trajectory of the material on the screen surface is circular or approximately circular, thus realizing the screening process.

[0004] After the screening process is completed, if it is necessary to clean the screen on the existing multi-stage automatic vibrating screen, it is usually necessary to unscrew the screws that fix the screen plate to remove it. This operation is time-consuming and inconvenient. Therefore, a multi-stage automatic vibrating screen is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a multi-stage automatic vibrating screen, which aims to improve the problem of inconvenient disassembly of the screen plate in the prior art.

[0029] 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.

[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a multi-stage automatic vibrating screen, including a base 1. The base 1 is configured to provide support for the installation of a spring-10 and to fix the position of a bracket 5. A connecting block 9 is elastically connected to the upper end of the base 1 via the spring-10. One end of the spring-10 is fixedly connected to the upper side of the base 1, and the other end of the spring-10 is fixedly connected to the bottom end of the connecting block 9. A screen frame 2 is fixedly connected to the rear end of the connecting block 9. The screen frame 2 is configured to provide support for the installation of a screen plate 3. The screen frame 2 vibrates due to the operation of a vibrator 7. A fixing block 13 is fixedly connected to the inner wall of the screen frame 2. The fixing block 13 is configured to install a mounting column 12 and also provides support for the installation of the screen plate 3. A mounting column 12 is fixedly connected to the upper end of the fixing block 13. The mounting column 12 is configured to install the screen plate 3. The screen plate 3 is snapped onto the outer wall of the mounting column 12. Two screen plates 3 are provided, and the screen plates 3 are connected to the screen frame 2. The vibration of the screen frame 2 screens the material. A clamping plate 8, L-shaped, is elastically connected to the front outer wall of the screen frame 2 via a spring 11. Moving the clamping plate 8 away from the outer wall of the mounting column 12 installs the screen plate 3 onto the mounting column 12. Then, releasing the clamping plate 8 causes it to pop out under the elastic force of the spring 11 until it contacts the side wall of the mounting column 12, thus fixing the screen plate 3. The outer wall of the clamping plate 8 is slidably connected to the inner wall of the screen frame 2. The inner rear wall of the card plate 8 contacts the side wall of the mounting column 12. One end of the second spring 11 is fixedly connected to the outer front wall of the screen frame 2, and the other end of the second spring 11 is fixedly connected to the outer wall of the card plate 8. The screen frame 2 is equipped with a vibrator 7, which is existing technology and has not been described in detail. A bracket 5 is fixedly connected to the outer wall of the base 1. The bracket 5 provides support for the installation of the feeding box 4. A feeding assembly is fixedly connected to the outer wall of the bracket 5. The feeding assembly is used for feeding materials.

[0031] Reference Figure 1 and Figure 3The feeding assembly includes a feeding box 4, which is wider at the top and narrower at the bottom. The feeding box 4 is used for feeding materials. The outer wall of the feeding box 4 is fixedly connected to the outer wall of the bracket 5. A feeding column 14 is rotatably connected to the inner wall of the feeding box 4. The feeding column 14 can rotate. By moving the insertion rod 17, the insertion rod 17 is moved away from the inner wall of the feeding box 4, which releases the restriction on the rotating handle 6, allowing the rotating handle 6 to be rotated. The angle of the feeding column 14 can be adjusted by rotating the rotating handle 6, and the feeding speed can be controlled by adjusting the angle of the feeding column 14. A through groove is opened on the inner wall of the feeding column 14, and a rotating shaft 15 is fixedly connected to the front end of the feeding column 14. A handle 6 is fixedly connected to the front end of 5. The handle 6 can drive the rotating shaft 15 and the feeding column 14 to rotate by rotating the handle 6. The front side of the handle 6 is elastically connected to the insertion rod 17 by spring 3 16. The rear outer wall of the insertion rod 17 is engaged in the feeding box 4 to fix the position of the handle 6. When the handle 6 leaves the inner wall of the feeding box 4, the fixing of the handle 6 can be released. The outer wall of the insertion rod 17 is slidably connected to the inner wall of the handle 6. The rear outer wall of the insertion rod 17 is engaged in the front inner wall of the feeding box 4. One end of the spring 3 16 is fixedly connected to the front outer wall of the handle 6, and the other end of the spring 3 16 is fixedly connected to the outer wall of the insertion rod 17.

[0032] Working principle: By moving the insert rod 17 to release the fixation of the rotating handle 6, the rotating handle 6 can be rotated. The rotation of the rotating handle 6 drives the rotating shaft 15 and the feeding column 14 to rotate, closing the lower opening of the feeding box 4. The material to be screened is placed in the feeding box 4. Then, the vibrator 7 is started. The operation of the vibrator 7 drives the screen frame 2 to vibrate. Then, the rotating handle 6 is rotated so that the material can fall onto the screen plate 3 through the feeding column 14. The position of the feeding column 14 is adjusted according to the required feeding speed. The position of the rotating handle 6 is fixed by releasing the insert rod 17 and engaging it on the inner wall of the feeding box 4, thereby fixing the feeding column 14. The material is screened through the screen plate 3. The screened material is collected separately. After screening is completed, the screen plate 3 can be moved upward and removed by moving the clamping plate 8 away from the outer wall of the mounting column 12 for easy cleaning.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
