Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a tidal vibrating bar feeder. Background Technology

[0002] The bar vibrating feeder is a device that combines uniform feeding and preliminary screening functions. It can continuously and uniformly supply lumpy and granular materials from the storage silo to the receiving device, and is often used in conjunction with coarse crushing equipment such as jaw crushers. This equipment can effectively remove fine materials and soil, achieve pre-screening, improve coarse crushing capacity, and features stable vibration, low energy consumption, resistance to clogging, robust structure, and easy maintenance. The enclosed body also prevents dust pollution. It is widely used in crushing and screening processes in industries such as metallurgy, mining, building materials, and chemicals.

[0003] Currently, the screens in the bar vibrating equipment commonly used in metallurgical mines are all fixedly installed on the equipment. During operation, the screens float up and down with the entire equipment; however, due to the irregular shape of the ore, it is very easy for the ore to get stuck and clogged during screening. This not only hinders the screening effect, but also seriously affects the feeding speed. Manual cleaning is not only time-consuming and labor-intensive, but also poses a significant safety hazard.

[0004] Based on the above-mentioned technical problems, this utility model proposes a tidal vibrating bar feeder. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tidal vibrating bar feeder to solve the above-mentioned technical problems.

[0006] This utility model is achieved through the following technical solution: a tidal vibrating bar feeder, including a frame, a feeding bin at the top of the frame, a vibrator at the bottom of the frame, a primary screening plate below the feeding bin, and a tidal screening component at an angle below the primary screening plate. The tidal screening component includes a bar screening component and a tidal generation component that are inclinedly arranged below the primary screening plate.

[0007] Furthermore, the bar screening assembly is inclined and includes multiple bars. The bottom end of the bar screening assembly is provided with a rotating shaft, which is rotatably connected to the frame. An energy storage device is provided at the end of the rotating shaft. The bars are slidably connected to the rotating shaft. The tide generating assembly is engaged with the upper end of the bar screening assembly.

[0008] Furthermore, the bars are divided into group A movable bars and group B movable bars, with each pair of group A movable bars and group B movable bars arranged at intervals.

[0009] Furthermore, the tide generating component is always in contact with the bars. The tide generating component includes a drive motor and an eccentric shaft. The eccentric shaft is rotatably connected to the frame. The drive motor drives the eccentric shaft to rotate, and the A group of movable bars and the B group of movable bars move alternately.

[0010] Furthermore, the primary screening plate is positioned diagonally above the tidal screening assembly, with the primary screening plate inclined relative to the ground. The bottom end of the primary screening plate is rotatably mounted on the side wall of the frame via a rotating shaft, and an angle adjustment device is provided at the top of the primary screening plate.

[0011] Furthermore, a blind plate is provided diagonally below the tidal screening component. A portion of the blind plate is located below the tidal screening component. The blind plate is pull-out and slidably mounted on the frame.

[0012] Furthermore, the frame is mounted on the base, and a shock-absorbing spring is provided between the frame and the base.

[0013] The beneficial effects of this utility model are as follows: A tidal vibrating bar feeder includes a frame, a feeding bin is provided at the top of the frame, a vibrator is provided at the bottom of the frame, a primary screening plate is provided below the feeding bin, and a tidal screening component is provided obliquely below the primary screening plate. The tidal screening component includes a bar screening component and a tidal generating component that are obliquely arranged below the primary screening plate. The tidal generating component causes the bar screening component to float up and down like tidal waves, which changes the gap between the bars, effectively preventing ore from clogging in the bar screening part and allowing the ore to fall quickly, thereby improving the screening efficiency and feeding capacity of the bar feeder.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] 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.

[0018] Example 1 like Figure 1-3 As shown, this embodiment discloses a tidal vibrating bar feeder, including a frame 1, which is mounted on a base 11. A damping spring 9 is installed between the frame and the base, and the damping spring 9 is evenly distributed around the contact surface between the frame 1 and the base 11. A feed hopper 2 is installed on the top of the frame 1, and a vibrator 3 is installed on the bottom of the frame 1. A primary screening plate 4 is installed below the feed hopper 2, and a tidal screening component is installed obliquely below the primary screening plate 4. The tidal screening component includes a bar screening component and a tidal generating component that are obliquely installed below the primary screening plate 4.

[0019] The tidal generating component consists of an eccentric shaft 51 and a drive motor, wherein the drive motor is a variable frequency motor 5. The eccentric shaft 51 is rotatably mounted on the frame 1, and one end of the eccentric shaft is connected to the variable frequency motor 5 through a coupling 52. The variable frequency motor 5 is mounted on the base 11.

[0020] The bar screening assembly consists of multiple identical, uniformly arranged bars and a rotating shaft 7. The rotating shaft 7 is rotatably mounted on the frame 1. The ends of the bars are mounted on the rotating shaft 7, and a limiting block is installed between the rotating shaft 7 and the bars to restrict the relative rotation of the bars and the rotating shaft 7. A coil spring is installed at one end of the rotating shaft 7, and the other end of the coil spring is fixed to the frame 1. Under the action of the coil spring, the bars deflect downward, causing the other end of the bars to press against the tide generating assembly.

[0021] like Figure 2As shown, the bars are divided into group A movable bars 6 and group B movable bars 61 according to their installation positions. Each pair of group A movable bars 6 and group B movable bars 61 is arranged with a gap between them, and the gap between them can be adjusted according to actual screening requirements. Under the action of the coil spring, the top of the bars is pressed against the surface of the eccentric shaft 51, and the eccentric vertices of the group A and group B movable bars are opposite to those of the eccentric shaft. That is, when group A movable bars 6 are at the highest point of the eccentric shaft, group B movable bars 61... When the B group of movable bars 61 is at its lowest position, and conversely when the B group of movable bars 61 is at its highest position, the A group of movable bars 61 is at its lowest position. By driving the eccentric shaft 51 to rotate, the B and A groups of movable bars move up and down in a tidal wave pattern between each adjacent pair. This allows the gap between the bars to change periodically, effectively preventing the ore from jamming or clogging the screen holes. Furthermore, the variable frequency motor 5 can change the rotation speed of the eccentric shaft 51 to adapt to different materials and different screening requirements, thereby improving the screening efficiency and feeding capacity of the bar feeder.

[0022] A primary screening plate 4 is installed diagonally above the tidal screening component. The bottom end of the primary screening plate 4 is rotatably mounted on the side wall of the frame 1 via a rotating shaft. An angle adjustment device is installed at the top of the primary screening plate 4. By adjusting the angle of the primary screening plate 4, the feeding speed of the ore can be controlled. The surface of the primary screening plate 4 has uniformly distributed filter holes, and the size of the holes can be selected according to the particle size requirements of the ore to achieve preliminary screening of the ore. The angle adjustment device is easy to operate and can be manually adjusted during use to meet the feeding speed requirements under different working conditions.

[0023] A blind plate 8 is installed diagonally below the tidal screening component. The blind plate 8 is slidably installed on the frame 1 and is pull-out, so that a material accumulation layer is formed between the blind plate 8 and the tidal screening component, thereby improving the utilization rate of the entire screen width direction, ensuring uniform feeding, and thus improving the screening accuracy.

[0024] In operation, the ore enters the device through the feed hopper 2 and falls onto the primary screen plate 4 for preliminary screening. The tilt angle of the primary screen plate 4 is manually adjusted according to the screening effect. The ore then falls onto the tidal screening component through the primary screen plate 4. The variable frequency motor 5 drives the eccentric shaft 51 to rotate. Since the other end of the bar is slidably mounted on the rotating shaft 7, and a coil spring is installed between the rotating shaft 7 and the frame 1, the movable bar can move up and down back and forth during the rotation of the eccentric shaft 51, forming a tidal wave shape, which widens the gap between the bars and allows irregular ore stuck in the gap to fall off. If there is irregular ore stuck between the bars, it can also be pushed forward by the bars or even crushed under the reciprocating movement of the bars, which can prevent the ore from clogging the screen holes and improve the screening effect. The screened ore enters the working section of the blind plate 8 through the tidal screening component. The blind plate 8 adjusts the ore distribution to ensure that the ore is evenly distributed on the device and that the equipment can supply material stably and quickly.

[0025] 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.
