Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, specifically a coal mine feed chute. Background Technology

[0002] Conveyors are commonly used in the process of transferring coal in coal mines. Conveyors are often equipped with guide chutes at the unloading point. The guide chutes are an essential component of the conveyor, used to guide and unload the coal on the conveyor, thus achieving more efficient transportation.

[0003] The existing Chinese utility model patent with publication number CN216661513U discloses a material guide chute for a coal mine conveyor, including a fixed frame for fixing its position. A conveyor belt is mounted on the opposite side of the fixed frame via rollers for conveying collected coal. A material guide chute is bolted to the top of the fixed frame near the center to prevent coal from falling during conveying. A hopper is located on the top of the material guide chute near its end face for easy loading of coal. A leak-proof component is fixedly connected to the side of the hopper near the end face of the material guide chute. The leak-proof component includes a sliding frame for easy movement of the baffle. Sliding grooves are formed on the opposite sides of the sliding frame. This utility model, by providing a hopper at the bottom of the material guide chute, maximizes the conveying efficiency of the coal, while the bolted fixing facilitates later maintenance and repair.

[0004] However, the existing plow-type unloaders have poor material guiding effect on both sides, making it inconvenient to guide and transport materials. At the same time, the poor material guiding effect of the existing plow-type unloaders means that the material guiding troughs cannot collect all the materials. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a coal mine material guide chute, which has advantages such as excellent material guiding effect and solves the above-mentioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a coal mine feed chute, comprising:

[0009] A support frame has a support rod movably connected to one side of its top. A fixing plate is fixedly installed on one side of the support rod. A guide plate, shaped like a "V", is fixedly installed on one side of the fixing plate. A spring is fixedly installed at the bottom of the guide plate. A support groove is fixedly installed at the bottom of the spring. A wear-resistant rubber strip is fixedly installed at the bottom of the support groove. A collection trough is fixedly installed at the bottom of the support frame. Two side plates are fixedly installed on the top two sides of the collection trough. A discharge trough is fixedly installed at the bottom of the collection trough. A guide plate, shaped like a triangle, is fixedly installed inside the discharge trough. An electric rotating shaft is fixedly installed at the top center of the guide plate. A baffle is movably connected to the top of the electric rotating shaft. Two support seats are fixedly installed on the bottom two sides of the guide plate.

[0010] As a preferred embodiment of this utility model, a conveyor belt is movably connected inside the support frame, and the conveyor belt is a structure used for conveying.

[0011] As a preferred embodiment of this utility model, a support plate is fixedly installed inside the support frame, and the support plate is a structure used for support.

[0012] As a preferred embodiment of this utility model, a support roller is fixedly installed on the top of the support plate, and the support roller is a structure used to support the conveyor belt.

[0013] As a preferred embodiment of this utility model, two guide blocks are fixedly installed on the top two sides of the support plate. The guide blocks are triangular in shape and are structures used for guiding materials.

[0014] As a preferred embodiment of this utility model, a base is fixedly installed at the bottom of the support frame, and the base is a structure used to support the bottom.

[0015] As a preferred embodiment of this utility model, a fixed frame is fixedly installed on one side of the top of the support frame, and a rotating device is fixedly installed on the top of the fixed frame. The rotating device is a structure used to drive the support rod to rotate.

[0016] Compared with the prior art, the present invention provides a coal mine feed chute, which has the following beneficial effects:

[0017] 1. This utility model supports the rotating device with a support frame. The operation of the rotating device can drive the rod to adjust the angle, so that the guide plate on one side of the fixed plate is in contact with the top of the conveyor belt. The contraction of the spring at the bottom of the guide plate can make the guide plate move up and down inside the support groove, thereby achieving a buffering effect. The three wear-resistant rubber strips at the bottom of the support groove can achieve a sealing and wear-resistant effect, improving the material collection effect.

[0018] 2. This utility model can collect materials through the collection trough, and the materials can be blocked by the two side plates. The operation of the electric rotating shaft at the top of the guide plate can drive the baffle to flip, thereby guiding the materials entering the collection trough. This makes it easier to send the materials out from the outlet on the left or right side of the bottom of the discharge trough, improving the convenience and practicality of the coal mine guide trough.
