Description

Technical Field

[0001] This utility model relates to the field of coal mining machinery, specifically to a bottom plate leveling mechanism. Background Technology

[0002] When repairing the floor of a coal mine, a smooth surface is generally required. Currently, the common practice is to use a hydraulic breaker to break the surface, followed by manual cleaning and then leveling. This method results in poor work quality and low efficiency. To improve efficiency, milling heads are sometimes used for back-and-forth milling. However, milling heads cannot create a smooth surface over large areas; furthermore, they require long arms for support, limiting their application in tunnels.

[0003] Utility model patent CN221760406U discloses a device for repairing coal mine roadway surfaces, including a vehicle body. The vehicle body is equipped with a powder spreading assembly, a milling and crushing assembly, and a leveling assembly. The milling and crushing assembly is located between the powder spreading assembly and the leveling assembly. The vehicle body includes two front wheels and two rear wheels, with the milling and crushing assembly located between the front and rear wheels. The powder spreading assembly and the leveling assembly are located on one side of the front and rear wheels, respectively. Two baffles are provided between the front and rear wheels on the vehicle body. The powder spreading assembly includes a hopper fixed in the frame of the vehicle body, one end of which is connected to a distributor, the discharge port of which faces the ground. The hopper contains a conveyor for transporting powder to the distributor. The milling and crushing assembly includes a hydraulic rocker arm mechanism and a roller mill cutter, the roller mill cutter being rotatably mounted on the hydraulic rocker arm mechanism. The hydraulic rocker arm mechanism is fixed to the vehicle body and is used to load and unload the drum milling cutter.

[0004] This coal mine roadway surface repair device integrates a powder spreading component, a milling and crushing component, and a leveling component onto a single vehicle body. This allows the vehicle to perform powder spreading, milling and crushing, and leveling operations within narrow roadways without the need for multiple large units, facilitating roadway surface repair work and improving efficiency. However, the disclosed structure of this coal mine roadway surface repair device does not allow for the external discharge of slag. Utility Model Content

[0005] In order to repair and level the base plate over a large area and discharge the slag, the technical solution adopted by this utility model is: a base plate leveling mechanism, including a support frame, a drive mechanism, a ring mounting chain, and several cutting teeth.

[0006] Several of the aforementioned cutting teeth are mounted on the annular mounting chain; the annular mounting chain is in transmission engagement with the drive mechanism;

[0007] The drive mechanism is mounted on the support frame and is used to drive the annular mounting chain to rotate cyclically, thereby driving several cutting teeth to cut and flatten the bottom plate and discharge the slag from one side.

[0008] Beneficial effects: While using several cutting teeth to cut and clean the bottom plate, it can also discharge the cleaned debris from one side, thereby improving the cleaning efficiency and effect of the bottom plate.

[0009] Based on the above, the annular mounting chain is arranged perpendicularly to the base plate, and the plurality of cutting teeth are arranged in multiple rows along the width direction of the annular mounting chain.

[0010] Based on the above, the plurality of cutting teeth in each row are arranged at equal intervals.

[0011] Beneficial effect: Improves cleaning efficiency.

[0012] Based on the above, the support frame is a rectangular support frame, and a pair of driving mechanisms are provided on the support frame. The driving mechanisms are distributed at both ends of the rectangular support frame, and the axis of the driving mechanism is perpendicular to the base plate.

[0013] Beneficial effect: It can improve structural strength.

[0014] Based on the above, multiple cutting teeth located at the bottom row are inclined downwards on the annular mounting chain to cut and flatten the bottom of the base plate.

[0015] Beneficial effect: Improves cutting efficiency.

[0016] Based on the above, the annular mounting chain includes multiple vertically arranged chain plates, and two adjacent chain plates are movably connected by a pin.

[0017] Based on the above, multiple cutting teeth located on the upper part of the chain plate are horizontally arranged to cut the side of the base plate.

[0018] Beneficial effect: It can expand the cleaning area.

[0019] Based on the above, a scraper is vertically arranged on the rear side of the support frame. The scraper is used to perform secondary leveling on the bottom plate after it has been cut and leveled by the cutting teeth.

[0020] Beneficial effect: Improves flatness.

[0021] Based on the above, the scraper is provided with mounting ear plates at its lower and upper parts, which are used to connect with the traveling mechanism to push the support frame to move.

[0022] Beneficial effect: Facilitates assembly.

[0023] This utility model has substantial features and progress compared to the prior art. Specifically, the bottom plate flattening mechanism provided by this utility model installs several cutting teeth on a ring mounting chain and connects the ring mounting chain with the drive mechanism to form a motion trajectory that rotates in one direction. This allows the bottom plate to be cut and cleaned by the cutting teeth while the slag is discharged from one side, thereby improving the cleaning efficiency and effect of the bottom plate.

[0024] Furthermore, by arranging several cutting teeth in multiple rows along the width of the annular mounting chain, the working surface of the cutting teeth in the vertical direction is increased, enabling large-area repair and one-time sweeping of the base plate, thereby further improving cutting and cleaning efficiency.

[0025] Furthermore, by installing a scraper on the rear side of the support frame, after the bottom plate is cut and cleaned using the cutting teeth, the scraper can be used to further flatten and smooth the bottom plate, further improving its flatness. Simultaneously, this bottom plate flattening mechanism can be easily installed and moved onto other vehicle bodies to complete the bottom plate flattening repair. Attached Figure Description
