Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an angle adjusting mechanism for the screen of a rotary vibrating screen. Background Technique

[0002] During the screening process of the existing rotary vibrating screen, the materials remaining on the screen usually need to gradually move to the edge of the screen under the vibration action and then slowly slide to the discharge port. This process takes a long time and affects the screening efficiency. Especially for materials with poor fluidity or large particles, the problem is particularly prominent. For this reason, we propose an angle adjusting mechanism for the screen of a rotary vibrating screen. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an angle adjusting mechanism for the screen of a rotary vibrating screen, which can flexibly adjust the angle of the screen according to the screening requirements, make it tilt towards the discharge pipe of the materials under the screen, thereby increasing the speed of screening the materials, shortening the sliding time of the materials on the screen, improving the screening efficiency, and being particularly suitable for materials with poor fluidity or large particles, and can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an angle adjusting mechanism for the screen of a rotary vibrating screen, including a base and a main body arranged above the base. A vibration assembly is installed inside the main body. The upper surface of the main body is respectively fixedly provided with a lower track and an upper track. A plurality of connecting rods are evenly and fixedly arranged between the upper track and the lower track. A circular rotating baffle is rotatably arranged outside the upper track and the lower track. A screen material outlet is arranged on the side surface of the rotating baffle. A screen material discharge pipe is connected to the outside of the screen material outlet. A screen is arranged on the inner surface of the lower track. A screen material cavity under the screen is arranged inside the main body, and the screen material cavity under the screen is communicated with a screen material discharge pipe arranged outside the main body. Two hinge bases are symmetrically arranged on the upper surface of the base. Hydraulic cylinders are hinged on both hinge bases. The movable ends of the hydraulic cylinders are hinged on hinge supports arranged on the outer side surface of the main body.

[0005] As a preferred technical scheme of the utility model, at least two rotating handles are arranged on the outer side surface of the rotating baffle.

[0006] As a preferred technical scheme of the utility model, a plurality of screw holes are evenly arranged on the side surface of the rotating baffle, and fixing bolts are threadedly connected in the screw holes.

[0007] As a preferred technical scheme of the utility model, a rotating column is fixedly arranged on each of the two side surfaces of the lower part of the main body perpendicular to the connection line of the two hinge supports. A fixing block is rotatably arranged outside the rotating column. Two support columns are symmetrically arranged on the upper surface of the base, and the top ends of the support columns are fixedly connected with the fixing blocks.

[0008] As a preferred technical solution of the present utility model, a plurality of connecting springs are uniformly arranged between the lower surface of the main body and the upper surface of the base.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: A hydraulic cylinder is hinged between the main body and the base of the vibrating screen. Through the lifting cooperation of the two hydraulic cylinders, the overall angle of the vibrating screen can be adjusted, so that the angle of the screen can be flexibly adjusted according to the screening requirements, making it tilt towards the discharge pipe of the undersize material, thereby increasing the speed of screening the material, enabling the oversize material to quickly slide to the lower part of the screen, shortening the sliding time of the oversize material, and improving the screening efficiency, especially suitable for materials with poor fluidity or large particles; at the same time, since the rotating baffle is rotatably arranged on the upper track and the lower track, it can be flexibly rotated to adjust the position of the oversize material outlet. When it is necessary to quickly discharge the oversize material, it can be rotated to the same side as the discharge pipe of the undersize material, and when it is necessary to retain the oversize material for further screening, it can be rotated to the higher side to prevent the oversize material from being discharged prematurely, improving the flexibility of use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-3, the present utility model provides a technical solution: a rotary vibrating screen screen angle adjustment mechanism, including a base 1 and a main body 2 arranged above the base 1. A vibration assembly is installed inside the main body 2, and the vibration assembly selects the vibration equipment commonly used in existing rotary vibrating screens. On the upper surface of the main body 2, a lower track 5 and an upper track 6 are respectively fixedly arranged. A number of connecting rods 7 are evenly and fixedly arranged between the upper track 6 and the lower track 5 for fixing the upper and lower tracks. The edge cross-sections of the upper track 6 and the lower track 5 are both T-shaped, and a circular rotating baffle 8 is rotatably arranged outside the upper track 6 and the lower track 5. A screen-over material outlet 9 is provided on the side surface of the rotating baffle 8, and a screen-over material discharge pipe 10 is connected to the outside of the screen-over material outlet 9. The inner surface of the lower track 5 is provided with a screen 4. When screening materials, the materials are put onto the screen 4, and the vibrating screen is driven by the vibration assembly to vibrate to screen the materials. The materials remaining on the screen 4 are discharged to the outside through the screen-over material outlet 9 from the screen-over material discharge pipe 10. Inside the main body 2, a screen-under material cavity is arranged below the screen 4, and the screen-under material cavity is communicated with a screen-under material discharge pipe 3 arranged outside the main body 2. The materials passing through the screen 4 enter the screen-under material cavity and are discharged from the screen-under material discharge pipe 3. The outlet position of the screen-over material discharge pipe 10 is farther from the center of the main body 2 than the outlet position of the screen-under material discharge pipe 3, and the screen-over materials and the screen-under materials are respectively transported to the corresponding receiving hoppers to avoid mutual influence.

[0016] Since the rotating baffle 8 is rotatably arranged on the upper track 6 and the lower track 5, it can rotate flexibly to adjust the position of the screen-over material outlet 9. When it is necessary to quickly discharge the screen-over materials, it can be rotated to the same side as the screen-under material discharge pipe 3. When it is necessary to retain the screen-over materials for further screening, it can be rotated to the higher side to prevent the screen-over materials from being discharged prematurely, improving the flexibility of use.

[0017] On the upper surface of the base 1, two hinged bases 13 are symmetrically arranged. Hydraulic cylinders 14 are hinged on both of the two hinged bases 13. The hydraulic cylinders 14 are connected to an external hydraulic pump and controlled by an external control switch. The movable ends of the hydraulic cylinders 14 are hinged on the hinged supports 15 arranged on the outer surface of the main body 2. Through the lifting cooperation of the two hydraulic cylinders 14, the overall angle of the vibrating screen can be adjusted, so as to flexibly adjust the angle of the screen 4 according to the screening requirements, making it inclined towards the screen-under material discharge pipe 3, thereby increasing the speed of screening materials, enabling the screen-over materials to quickly slide to the lower part of the screen 4, shortening the sliding time of the screen-over materials, and improving the screening efficiency, especially suitable for materials with poor fluidity or larger particles.

[0018] One of the hinged bases 13 is arranged below the screen-under material discharge pipe 3, so that the main body 2 can only be adjusted in the direction corresponding to the screen-under material discharge pipe 3 when driving the angle adjustment of the screen 4, ensuring smooth discharging.

[0019] Preferably, at least two rotating handles 11 are provided on the outer surface of the rotating baffle 8. Workers can push the rotating baffle 8 to rotate through the rotating handles 11, thereby adjusting the orientation of the oversize material outlet 9. The operation is simple and convenient to use.

[0020] Further preferably, a plurality of screw holes are evenly formed on the side surface of the rotating baffle 8. A fixing bolt 12 is threadedly connected in the screw hole. The rotating baffle 8 is fixed on the upper track 6 and the lower track 5 through the fixing bolt 12, so as to prevent it from rotating during the vibration screening process and affecting the screening.

[0021] Optionally, a driving device such as a driving motor can be provided on the outer surface of the main body 2, and the rotating baffle 8 is driven to rotate in a form of gear transmission, so as to automatically adjust the position of the oversize material outlet 9 on the rotating baffle 8.

[0022] Preferably, a rotating column 16 is fixedly provided on each of the two side surfaces of the lower part of the main body 2 perpendicular to the connection line of the two hinge supports 15. A fixing block 17 is rotatably arranged on the outside of the rotating column 16. Two support columns 18 are symmetrically arranged on the upper surface of the base 1. The top end of the support column 18 is fixedly connected to the fixing block 17. When the main body 2 adjusts the angle driven by the two hydraulic cylinders 14, it rotates with the axis of the rotating column 16 as the rotation axis. The rotating column 16 rotates in the through hole formed in the fixing block 17. The fixing block 17 plays a fixing role on the rotating column 16 and the main body 2, etc., and at the same time cooperates with the support column 18 to support it, ensuring the stability of the vibrating screen during operation.

[0023] Further preferably, a plurality of connecting springs 19 are evenly arranged between the lower surface of the main body 2 and the upper surface of the base 1. The connecting springs 19 can play an auxiliary supporting effect, and at the same time can play a buffering and shock-absorbing role when adjusting the angle of the main body 2 and during the vibration screening of the main body 2, further improving the stability of the vibrating screen during operation.
