Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a cloth feeding device for a vibrating screen and a vibrating screen. Background Technique

[0002] A vibrating screen works by using the reciprocating spiral vibration generated by the vibration exciter. The upper rotating weight of the vibration exciter makes the screen surface generate a planar gyratory vibration, while the lower rotating weight makes the screen surface generate a conical gyratory vibration. The combined effect makes the screen surface generate a compound spiral vibration. Its vibration trajectory is a complex space curve. The projection of this curve on the horizontal plane is a circle, and the projection on the vertical plane is an ellipse. By adjusting the exciting force of the upper and lower rotating weights, the amplitude can be changed. By adjusting the spatial phase angle of the upper and lower weights, the curve shape of the screen surface movement trajectory can be changed and the movement trajectory of the materials on the screen surface can be changed.

[0003] The vibrating screen has high efficiency, light weight, a complete and diverse series, and multiple levels, and can meet the needs for screening dry materials. However, there are still some problems in the process of using the vibrating screen. Generally, the filter screen of the vibrating screen is supported by the structures at both ends. In actual use, under the action of the weight of the materials and the weight of the filter screen itself, the middle part of the filter screen is prone to sag downward, causing the materials to easily concentrate in the middle part of the filter screen. This makes the middle part of the filter screen subject to greater wear after long-term continuous operation, while the outer edge of the filter screen hardly works. The scrapping of the filter screen will cause waste and increase the production cost.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a material distribution device for a vibrating screen provided by the utility model; Figure 2 A schematic structural diagram of a preferred embodiment of the vibrating screen provided by the utility model; Figure 3 for Figure 2 The cross-sectional structure diagram of the filter frame in the vibrating screen is shown. The material distribution device for the vibrating screen comprises: a feed hopper 1, the bottom end of which is vertically rotatably connected to a rotating frame 2 with a closed bottom end;

[0021] A feed pipe 3 is vertically connected to the bottom end of the rotating frame 2. The feed pipe 3 is eccentrically arranged at the bottom end of the rotating frame 2. An outer gear ring 4 is laterally fixedly connected to the upper part of the outer surface of the rotating frame 2. A mounting seat 5 is fixedly connected to the lower part of the outer surface of the feed hopper 1. A motor 6 is fixedly connected to the outer surface of the mounting seat 5. A gear 7 meshing with the outer gear ring 4 is fixedly connected to the surface of the output shaft of the motor 6.

[0022] The central axes of the feed hopper 1 and the rotating frame 2 are located on the same straight line.

[0023] When the material distribution device is in operation, the rotating frame 2 is driven to rotate by the operation of the motor 6. During the operation of the motor 6, the gear 7 on the surface of the output shaft will drive the outer gear ring 4 meshing with it to rotate, and the rotation of the outer gear ring 4 will drive the rotating frame 2 to rotate. During its rotation, the material in the feed hopper 1 will be discharged through the discharge pipe 3 at the bottom end of the rotating frame 2. Since the discharge pipe 3 is eccentrically set, the discharged material will continue to descend in a spiral shape, so that it can be evenly distributed in the vibrating screen.

[0024] A vibrating screen includes the above-mentioned cloth feeding device for a vibrating screen, and also includes a horizontally arranged platform 8. On both sides of the upper surface of the platform 8, transverse brackets 9 are fixedly connected along its length direction. At the top of each of the two transverse brackets 9, a plurality of buffer springs 10 are vertically fixedly connected. At the top of each of the plurality of buffer springs 10, a connecting seat 11 is horizontally fixedly connected. A filter frame 12 with an open top and front is horizontally fixedly connected between the plurality of connecting seats 11 on both sides. Inside the filter frame 12, a plurality of filter mesh plates 14 that are inclined downward from back to front are fixedly connected along its length direction. The plurality of filter mesh plates 14 are evenly spaced along the height direction of the filter frame 12.

[0025] At the rear end of the upper surface of the platform 8, a rear device frame 17 adapted to the feed hopper 1 is vertically fixedly connected.

[0026] The feed hopper 1 is directly installed inside the rear device frame 17, and its bottom end extends to the rear part above the filter frame 12. The material discharged from its bottom end will be directly discharged onto the uppermost filter mesh plate 14 inside the filter frame 12. Then, with the continuous shaking of the vibrating screen, the screening operation of the material can be carried out.

[0027] The plurality of buffer springs 10 can buffer the impact force generated by the vibration, prevent it from directly affecting the two rows of transverse brackets 9, and improve the stability of the transverse brackets 9 and the service life of the device.

[0028] Inside the filter frame 12 and below the plurality of filter mesh plates 14, a plurality of support frames 15 are horizontally fixedly connected.

[0029] The plurality of support frames 15 can support the plurality of filter mesh plates 14, ensure that the cross-sections of the plurality of filter mesh plates 14 can always maintain a horizontal state without curvature, and thus ensure that the material on them will not concentrate in the middle of the filter mesh plates 14, will not cause excessive wear on the middle of the filter mesh plates 14, improve the service life of the filter mesh plates 14, and also indirectly reduce the production cost.

[0030] On the outer surface of the filter frame 12, a plurality of vibration motors 13 are fixedly connected.

[0031] The vibration motors 13 play a vibrating effect. They are prior art and will not be elaborated here.

[0032] At the bottom end of the platform 8, a plurality of support pads 16 are fixedly connected.

[0033] The support pads 16 play a supporting effect.

[0034] The working principle of the cloth feeding device for a vibrating screen and the vibrating screen provided by the present utility model is as follows:

[0035] When the fabric device is in operation, the rotation of the rotating frame 2 is driven by the operation of the motor 6. During the operation of the motor 6, the gear 7 on the surface of its output shaft drives the external tooth ring 4 meshing with it to rotate. When the external tooth ring 4 rotates, it drives the rotating frame 2 to rotate. During the rotation process, the material in the feed hopper 1 is discharged through the discharge pipe 3 at the bottom of the rotating frame 2. Since the discharge pipe 3 is eccentrically arranged, the discharged material will continuously descend in a spiral shape, so that it can be evenly distributed in the vibrating screen. Then, driven by the vibrating motor 13, the vibrating screen will screen the material inside it.

[0036] Compared with the related technology, the fabric device for vibrating screen and the vibrating screen provided by the present utility model have the following beneficial effects:

[0037] The present utility model provides a fabric device for vibrating screen and a vibrating screen. By setting the rotating frame 2 and multiple support frames 15, in the fabric device, by setting the rotating frame 2, during the rotation of the rotating frame 2, the material in the feed hopper 1 is discharged from the discharge pipe 3 at its bottom. Since the discharge pipe 3 is eccentrically arranged, the material will form a spiral shape during the discharge process, so as to ensure the uniform distribution of the material. At the same time, multiple horizontal support frames 15 are arranged at the bottom of the multiple filter plates 14 in the vibrating screen, which can support the filter plates 14 and ensure that they are always in a horizontal state, so as to prevent the material from accumulating in the middle, improve the service life of the filter plates 14, and thus reduce the production cost.
