Description

Technical Field

[0001] This utility model relates to the field of vibrating coal feeder technology, specifically a vibrating coal feeder. Background Technology

[0002] Vibrating feeders are widely used in the coal industry. They feed raw coal and pulverized coal evenly or quantitatively from storage bins to receiving equipment. They feature rapid start-up, smooth shutdown, low maintenance, convenient installation, and simple structure, making them ideal feeding equipment in the coal industry.

[0003] When the vibrator is working, the feed trough will vibrate periodically in a linear direction along its inclination. Specifically, when the vertical component of the vibration acceleration of the feed trough is greater than the acceleration due to gravity, the material in the trough is thrown up and jumps forward along a parabolic trajectory. Due to the continuous excitation of the vibration source, the feed trough vibrates continuously, and the coal in the trough jumps forward continuously, thereby realizing the conveying and feeding of materials.

[0004] When the vibrating coal feeder is running, the raw coal inside the storage tank will also vibrate, causing too much coal to participate in the vibration. At the same time, different types of coal have different moisture content, and coal with too much moisture may cause a large amount of coal to accumulate at the discharge port, affecting the discharge speed. Therefore, we propose a vibrating coal feeder. Utility Model Content

A pointed cone 21 is provided at the upper end of each material distribution shaft 22, and evenly distributed eccentric wheels 26 are fixedly connected to the middle of each material distribution shaft 22. The rhombus block 23 and the anti-blocking mechanism 2 also include a motor 27. The motor 27 is fixedly connected to the right side of the fixed base 28. The output group of the motor 27 is fixedly connected to the middle of the rightmost eccentric wheel 26.

Feeding mechanism 3 includes vibrating frame 31, mounting base 32, connecting component 33, hook 1 34 and vibrating motor 35.

Hook 1 34 distributed front and back is fixedly connected to both sides of vibrating frame 31. Hook 1 34 is respectively configured to cooperate with the vertically adjacent connecting component 33. The lower end of feeding channel 7 is located inside vibrating frame 31. Mounting base 32 is fixedly connected to the lower end of vibrating frame 31.

The upper end of the upper connecting plate 331 is fixedly connected with a barb, which is respectively engaged inside the lower hook 5. In use, the vibration motor 35 is started, which drives the mounting base 32 and the vibration frame 31 to vibrate. The springs 332 are repeatedly contracted and rebounded due to the vibration of the vibration frame 31 and their own elastic potential energy, which increases the vibration effect of the vibration frame 31. At the same time, the vibration is transmitted through the various parts of the connecting assembly 33, which causes the coal storage tank and the coal inside to vibrate. The coal falls from the feeding channel 7 and is discharged through the vibration frame 31.

[0027] It also includes a control switch group 4, which is located on the left side of the support plate 1, and the input end of the control switch group 4 is electrically connected to an external power supply.

[0028] The working principle of the vibrating coal feeder provided by this utility model is as follows: The feeding channel 7 is fixedly connected to the lower end of the coal storage tank. The hook 5 on the upper surface of the support plate 1 is connected to the outer surface of the coal storage tank by a steel cable. During use, the vibration motor 35 is started, driving the mounting base 32 and the vibration frame 31 to vibrate. The spring 332 is affected by the vibration of the vibration frame 31 and its own elastic potential energy, repeatedly contracting and rebounding, increasing the vibration effect of the vibration frame 31. At the same time, the vibration is transmitted through the various parts of the connecting assembly 33, causing the coal storage tank and the coal inside to vibrate. The coal block falls from the feeding channel 7 and passes through the vibration frame 31. The output shaft of the motor 27 drives the eccentric wheel 26 to rotate, and the connecting rod 25 rotates synchronously with the eccentric wheel 26. The upper end of the connecting rod 25 drives the vertically adjacent bulk shaft 22 to slide back and forth between the two cylindrical seats 24. The pointed cone 21 and the rhomboid block 23 reduce the resistance when the bulk shaft 22 slides back and forth. At the same time, the rhomboid block 23 slides back and forth synchronously, realizing the crushing of the coal block over a larger area. The crushed coal block is difficult to gather, making it easier to feed. The dust cover 6 reduces the dust entering the motor 27 and the eccentric wheel 26, extending the service life.

[0029] It is worth noting that the motor 27 disclosed in the above embodiments can be a YDS series geared motor, the vibration motor 35 can be a YBZU vibration motor, and the control switch group 4 is provided with switch buttons corresponding to the motor 27 and the vibration motor 35 for controlling their switching operation.
