Description

Technical Field

[0001] The utility model relates to the technical field of coal feeder equipment, in particular to a coal feeder funnel. Background Art

[0002] The hopper plays a key role in the coal supply system. It ensures the continuous operation of the coal feeder through stable feeding and prevents equipment shutdown or production interruption due to uneven or interrupted coal supply. However, the hopper usually adopts an integral welded structure. This design brings several problems in practical application. First, when a part of the hopper, such as the support wall, is damaged, due to its integral welded characteristics, the repair becomes extremely complicated and expensive. This usually means that the entire hopper needs to be replaced, not just the damaged part. This not only leads to significant material waste, but also increases maintenance costs and downtime, thereby affecting production efficiency.

[0003] In addition, the coal will have a strong impact on the inner wall of the funnel during the falling process. This impact will cause rapid wear of the inner wall of the funnel, thereby reducing its working life. Frequent wear not only requires the replacement of the funnel, but also affects the fluidity of the coal, further aggravating the instability in the production process. Therefore, in order to extend the service life of the funnel and reduce maintenance costs, effective design and material improvement measures must be taken to reduce the impact of impact and wear on the funnel. Utility Model Content

[0004] The purpose of the utility model is to provide a coal feeder funnel to solve the problem that the size of the short single column becomes shorter, the original test bench cannot meet the requirements of the modified single column test, and at the same time, the original vertical test bench cannot effectively compress the single column, resulting in unstable data during the test. In addition, the lack of effective liquid collection design causes liquid to pollute the environment or cannot be effectively collected and treated.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a coal feeder hopper is installed between the coal bunker and the hydraulic gate, including a support frame and an anti-collision plate.

[0006] The support frame is a rectangular hollow trough body, which is composed of support plates and connecting plates spliced in pairs. The two support plates are symmetrically arranged, and the front and rear ends of the support plates are symmetrically provided with slide grooves. The bottom ends of the slide grooves are provided with limited stoppers. Connecting plates are provided in the slide grooves on the opposite end faces of the two support plates. The connecting plates are slidably matched with the support plates and abut against the limited stoppers.

[0007] An anti-collision plate is provided in the support frame. The anti-collision plates are arranged in a rectangular shape and abut against each other.

Slide rods are respectively provided in the through holes. The slide rods pass through the through holes and the linkage holes, and the anti-collision plate slides on the slide rods. Reset springs are provided between the anti-collision plate and the support plate and the connecting plate, and are sleeved on the slide rods. One end of the reset spring abuts against the anti-collision plate, and the other end abuts against the support plate and the connecting plate.

[0008] Preferably, a limit block is provided at the contact end of the sliding rod with the anti-collision plate, the limit block is fixedly connected to the anti-collision plate, and a thread groove is opened at the other end, and a double nut is screwed on the thread groove, and the double nut conflicts with the outer wall of the support frame.

[0009] Preferably, it also includes an angle steel, which is arranged at the circumferential connection of the outer side of the support plate and the connecting plate. The inner wall of the angle steel is in contact with the support plate and the connecting plate. A screw is provided on the angle steel, and the screw is screwed into the threaded holes opened on the support plate and the connecting plate.

[0010] Preferably, the support plate and the connecting plate are both provided with a transversely extending extension portion, the extension portion at the bottom end is connected to the hydraulic gate plate, and the transverse end at the top end is connected to the coal bin, and a number of positioning holes are opened on the extension portion, and the positioning holes are provided with through screws, which are screwed into the threaded holes reserved on the hydraulic gate plate and the coal bin respectively.

[0011] Preferably, a number of support rods are evenly distributed between the lateral ends of the support plate and the connecting plate to increase stability.

[0012] Preferably, a rubber shell is sleeved on the limit block to reduce the impact on the limit block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] A support frame is formed by opening a chute on the support plate and splicing the connecting plate onto the support plate. The support frame is connected to the coal bunker and the hydraulic gate through the positioning holes on the extension part. Through screws are installed in the positioning holes to ensure the firmness of the connection. Angle steel is provided at the external connection of the support frame, and screws are installed on the angle steel.

When it is damaged and replaced, the whole needs to be disassembled and replaced. Now, when replacing, only the damaged part needs to be replaced and repaired, without having to replace the funnel as a whole.

[0027] Example 2: Please refer to Figure 3 , based on Example 1, further comprising the following structure:

[0028] The support frame 3 is provided with an anti-collision plate 6. The anti-collision plate 6 is arranged in a rectangular shape and abutted against each other in pairs. The anti-collision plate 6 is mainly used to prevent impact and protect the support frame 3 from being hit or collided with coal. Its rectangular arrangement and the design of abutting against each other in pairs help to cover the inner wall of the support frame 3 and enhance the overall anti-collision effect. A number of linkage holes are provided on the anti-collision plate 6. The linkage holes are holes provided on the anti-collision plate 6 for docking with the through holes of the slide rod 7. The linkage holes enable the anti-collision plate 6 to slide on the slide rod 7. Through holes corresponding to the linkage holes are provided on the support plate 301 and the connecting plate 302. Slide rods 7 are respectively provided in the through holes. The slide rods 7 pass through the linkage holes on the anti-collision plate 6 and the support plate 301 and the connecting plate 302. The through hole on it enables the anti-collision plate 6 to slide on it, and the slide bar 7 also provides a guiding function to ensure the stability of the anti-collision plate 6 during the sliding process. The slide bar 7 passes through the through hole and the linkage hole, and the anti-collision plate 6 slides and fits on the slide bar 7. A return spring 8 is provided between the anti-collision plate 6 and the support plate 301 and the connecting plate 302.
