TECHNICAL FIELD

[0001] The present application relates to a kind of buffer coal bunker discharge hopper, belong to a kind of coal mine equipment parts. BACKGROUND

[0002] Coal bunker hopper, coal feeder coal discharge port is the extremely important link in the process of coal mine production and transportation, is in throat position, it plays a very important role for adjusting and buffering coal transportation.We use fixed funnel now, in the long-term use process, we find that it has many drawbacks:

[0003] (1) in the process of coal production, raw coal contains gangue amount is larger, because of the rich water resources in underground, coal flow is higher in moisture content, gangue is easy to produce mudification phenomenon when meeting water, cause coal, gangue mixture viscosity is higher, make underground raw coal bunker outlet frequent occurrence of blocking accident.

[0004] (2) the structure of coal bunker hopper is in the upper opening and vertical section of coal bunker, generally impossible to occur blocking accident, according to the principle of fluid mechanics, coal flow moves vertically in coal bunker, when the cross section of coal bunker is reduced, the lateral force received will increase, cause the density of coal flow to be larger, friction between each other increases, flow is blocked, prone to blocking accident.

[0005] (3) when dealing with blocking failure, maintenance personnel need to use drill and other tools to dredge, the retention in the bunker exists high falling danger, brings certain safety hazard to production.

[0006] (4) when dealing with blocking failure, it will affect the belt conveyor stop running, motor, speed reducer, roller and other equipment frequent start will cause certain current, mechanical impact, affect the service life of equipment. SUMMARY

[0018] The content of the present application is further described as follows:

[0019] The buffer type coal bunker discharging hopper of the present application is provided with a buffer device at the outlet position of the hopper to buffer the falling coal and dredge the jammed coal.

[0020] Specifically, the bottom of the hopper outlet 1 is provided with an inclined plate 2 inclined to one side, and a buffer plate 3 is arranged on the other side, one end of the buffer plate 3 is hingedly connected to the edge of the hopper outlet 1, and the other end is provided with a downward rubber baffle 4.

[0021] The buffer plate is used to buffer the coal falling at a certain speed, avoiding direct falling impact on the coal conveyor.

[0022] When the buffer coal is blocked, it is usually necessary to manually remove the blockage using tools. The device is connected to a vibration mechanism outside the buffer plate 3, and the buffer plate 3 is connected to the buffer spring 5 on both sides. The other end of the buffer spring 5 is connected to the adjustment rod 6, which is inserted into the fixed distance adjusting hole 7. The position of the adjustment rod 6 in the fixed distance adjusting hole 7 can adjust the compression length of the buffer spring 5. The buffer plate 3 is a hinged plate with one side flush with the side of the funnel outlet 1. The buffer plate 3 has a right angle position on both sides of the connecting column, which is connected to the buffer spring 5.

[0023] The adjustment rod 6 is a screw rod with the same length direction as the buffer spring 5. The fixed distance adjusting hole 7 is a fixed nut cylinder. The adjustment rod 6 is screwed into the nut cylinder, and the compression length of the buffer spring 5 is adjusted by rotating the adjustment rod. The length of the buffer spring can be adjusted by the adjustment rod to adjust the position of the buffer plate.

[0024] The buffer spring is used for resetting. The vibration mechanism regularly or irregularly vibrates at the funnel outlet, which can remove the blocked coal.

[0025] In the device, the vibration mechanism includes a reciprocating motor 8 and a reciprocating rope 9. The lower end of the reciprocating rope 9 is connected to the buffer plate 3. The housing of the reciprocating motor 8 is fixed to the outside of the funnel outlet 1. The output shaft of the reciprocating motor 8 is wound around the upper end of the reciprocating rope 9. The reciprocating motor 8 operates in forward and reverse directions at intervals to drive the reciprocating rope 9 up and down. The reciprocating rope 9 vibrates up and down with the buffer plate 3. The reciprocating movement of the reciprocating motor removes the blocked coal.

[0026] To avoid the failure of the motor agent to remove the material, a manual vibration rod 10 is also provided. One end of the manual vibration rod 10 is connected to the buffer plate 3, and the other end is connected to the pull rope 11. The middle of the manual vibration rod 10 is hingedly connected to the funnel outlet 1.

[0027] By pulling the pull rope, the rear end of the manual vibration rod 10 is driven up and down, the buffer plate is moved up and down, and the blocked coal is removed.

[0028] The buffer funnel of the device: the existing funnel front guard plate is modified to be movable forward and backward and expandable. It can expand and contract forward and backward, providing a basic condition for unblocking the jammed bin. The buffer spring stretches the buffer plate, better playing a buffering role. The motor drives the front guard plate to expand and vibrate forward and backward to unblock.
