Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, and more specifically, to a vibrating bar feeder for ore processing. Background Technology

[0002] A vibrating bar feeder is a device that uses vibration to convey materials and is widely used in industries such as mining, metallurgy, coal, and building materials. Its working principle is based on resonance; the excitation force generated by the vibrator causes the machine body to reciprocate periodically in a specific direction, thereby driving the bars installed on the machine body. This causes the material to be subjected to continuous and uniform vibration between the bars, achieving material conveying and feeding.

[0003] A search revealed that utility model patent CN216104931U discloses a bar vibrating feeder for a jaw crusher, comprising support columns, with two sets of support columns arranged symmetrically from left to right. Each set of support columns has two columns. A pad is fixedly installed at the lower end of each support column. Two first reinforcing rods are fixedly installed between two adjacent support columns, and two second reinforcing rods are fixedly installed between two adjacent support columns. A first connecting member is installed at the upper end of each support column, and two springs are installed at the upper ends of the two springs. A second connecting member is installed at the upper ends of the two springs. This bar vibrating feeder for a jaw crusher achieves material screening by using vibrating bars, a fine material outlet, a discharge hopper, and a fine material chute in coordination. This prevents fine materials from entering the jaw vibrator for secondary crushing, reduces workload, increases overall output, has a long service life, and a simple structure.

[0004] However, the aforementioned patents have the following shortcomings: the feeder has a fixed height, which is inconvenient for feeding jaw vibrators of different heights, resulting in poor practicality; and dust is generated during the ore feeding process, affecting the surrounding environment. Therefore, we propose a vibrating bar feeder for ore processing. Utility Model Content

[0027] Example:

[0028] Please see Figure 1-5 A vibrating bar feeder for ore processing includes four bases 1. A square cylinder 2 is fixedly connected to the top surface of each of the four bases 1. An electric hydraulic cylinder 3 is fixedly installed on the top surface of each of the four bases 1 and inside the square cylinder 2. Two of the electric hydraulic cylinders 3 have short square columns 4 fixedly connected to their top ends, and two other electric hydraulic cylinders 3 have tall square columns 5 fixedly connected to their top ends. Lower support plates 6 are fixedly connected to the top ends of the two short square columns 4 and the two tall square columns 5. A set of springs 7 is fixedly connected to the top surface of each of the four lower support plates 6. Upper support plates 8 are fixedly connected to the top ends of the four sets of springs 7.

A dust collection mechanism 10 is installed on the top of the feeding bins 9, and a vibrating motor 25 is fixedly installed on the bottom surface of the feeding bins 9. A moving mechanism 11 is provided between every two square cylinders 2.

[0029] In this embodiment, multiple electric hydraulic cylinders 3 drive two short square columns 4 and two tall square columns 5 to move up and down synchronously. At the same time, the feed bin 9 is tilted to ensure that the ore can move within the inner cavity of the feed bin 9.

[0030] For details, please refer to Figure 1 and Figure 4 The dust collection mechanism 10 includes a dust collection hood 12 fixedly connected to the top surface of the feeding bin 9. A dust collection box 13 is fixedly connected to the top surface of the dust collection hood 12. A dust collection pipe 14 is fixedly sleeved on one side of the dust collection box 13. The end of the dust collection pipe 14 is fixedly sleeved to the inner cavity of the dust collection hood 12 and fixedly connected to a dust collection disc 15. A dust collection pump 17 is fixedly installed on the other side of the dust collection box 13. The input end of the dust collection pump 17 extends into the inner cavity of the dust collection box 13. A filter screen 16 is fixedly sleeved in the inner cavity of the dust collection box 13. A sealing door 18 is hinged to the outer side of the dust collection box 13.

[0031] In this embodiment, the dust collected in the dust collection box 13 is cleaned by opening the sealed door 18.

[0032] For details, please refer to Figure 1 and Figure 2 The moving mechanism 11 includes a mounting plate 19 fixedly connected between two square cylinders 2. Two electric push rods 20 are fixedly mounted on the top surface of the mounting plate 19. The output ends of the two electric push rods 20 extend to the bottom of the mounting plate 19 and are fixedly connected to moving wheels 21.

[0033] In this embodiment, the electric push rod 20 can drive the moving wheel 21 to move down and support the feeder, so that the moving wheel 21 can drive the device to move.

[0034] For details, please refer to Figure 1 and Figure 3 The bottom of the feeding bin 9 is fixedly fitted with a discharge hopper 23. Multiple screening vibrating rods 26 are arranged in the inner cavity of the feeding bin 9 and above the discharge hopper 23. The top surface of the screening vibrating rods 26 is in contact with the bottom surface of the inner cavity of the feeding bin 9. A fine material chute 24 is fixedly fitted at the bottom end of the discharge hopper 23.

[0035] For details, please refer to Figure 1 and Figure 2 The four square tubes 2 are respectively fixedly connected by a first connecting rod 22, and the two short square columns 4 and the two tall square columns 5 are respectively fixedly connected by a second connecting rod 27.

[0036] For details, please refer to Figure 1 and Figure 2 A control panel 28 is fixedly installed on the outside of one of the square tubes 2, and the sides of the short square column 4 and the tall square column 5 are respectively attached to the inner wall of the square tube 2.

[0037] In this embodiment, the device is controlled by the control panel 28, and the inner wall of the square tube 2 is used to support the short square column 4 and the tall square column 5 to ensure the stability of the short square column 4 and the tall square column 5.

[0038] For details, please refer to Figure 5 A sliding rod 29 is fixedly connected to the bottom surface of the upper support plate 8, and the bottom end of the sliding rod 29 is movably connected to the lower support plate 6.

[0039] In this embodiment, the upper support plate 8 is limited by the movable cooperation between the lower support plate 6 and the slide bar 29, so that the upper support plate 8 and the feeding bin 9 can only move up and down.

[0040] Working Principle: In operation, firstly, the electric push rod 20 is activated, driving the moving wheels 21 downwards. This allows the multiple moving wheels 21 to support the feeder, enabling one end of the feed bin 9 on the feeder to be moved above the inlet of the jaw vibrator. Then, the electric push rod 20 is activated, driving the moving wheels 21 upwards until the bottom surface of the base 1 contacts the ground. Next, multiple electric hydraulic cylinders 3 are activated, driving the two short square columns 4 and two tall square columns 5 to move synchronously upwards or downwards, thereby adjusting the height of one end of the feed bin 9. This ensures that one end of the feed bin 9 is positioned a certain distance above the inlet of the jaw vibrator. Then, the vibration motor 25 is activated, causing the feed bin 9 to vibrate. Simultaneously, the ore to be fed is placed into the other end of the feed bin 9, allowing the ore to vibrate. The inner cavity of the hopper 9 moves. When the ore moves above the screening vibrating bar 26, the fine material falls into the discharge hopper 23 through the gap between the two screening vibrating bars 26, and the fine material in the discharge hopper 23 is discharged from the fine material chute 24, avoiding the fine material from entering the jaw vibrator for secondary crushing, thus reducing the workload of the jaw vibrator. The coarse material that is not filtered out enters the jaw vibrator from the end of the feed hopper 9. Finally, the dust pump 17 is started to draw air from the inner cavity of the dust collection box 13. The negative pressure in the inner cavity of the dust collection box 13 causes the suction pipe 14 and the dust collection disc 15 to exert suction. The suction of the dust collection disc 15 is used to draw the dust generated by the ore vibration screening into the inner cavity of the dust collection box 13. The dust is then trapped in the inner cavity of the dust collection box 13 by the filter screen 16 and collected.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
