Description

Technical Field

[0001] This utility model relates to the field of mining car technology, and in particular to a self-cleaning mining car. Background Technology

[0002] Mining cars are narrow-gauge railway vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches. Mining cars are classified into five main categories according to their structure and unloading method: fixed mining cars, material cars, flatbed cars, tipper mining cars, single-sided curved rail side-discharge mining cars, bottom-discharge mining cars, and shuttle mining cars. Mining car wheels have flanges on the inner side, with a certain gap between the flanges and the rails. The tread surface where the wheels contact the rails is conical. In the process of transporting coal and ore, existing mining cars are not convenient for quickly cleaning the coal and ore accumulated at the bottom of the car cavity, which increases the workload of workers and reduces the unloading efficiency of the mining cars. Furthermore, when encountering bumpy roads during transportation, the materials inside the mining cars are prone to spillage, resulting in resource waste. Therefore, a self-cleaning bottom mining car is proposed.

[0003] Therefore, it is necessary to invent a self-cleaning mine car to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning mine car to solve the problem mentioned in the background art that materials inside the mine car are easily spilled when encountering bumpy roads during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning mine car, including a base, with extension plates fixedly connected to both sides of the base, and lifting mechanisms fixedly connected to the middle of the surfaces of the two extension plates, a motor housing threadedly connected to one side of one set of lifting mechanisms, a rotating mechanism fixedly connected inside the motor housing, a material hopper fixedly connected to one end of the rotating mechanism, a sliding groove provided on the inner wall of the material hopper, and a sealing mechanism slidably connected inside the sliding groove.

[0006] Preferably, the lifting mechanism includes two sets of hydraulic rods fixedly connected to the middle of the surface of the extension plate. One end of each of the two hydraulic rods is fixedly connected to a telescopic frame. One side of each of the two telescopic frames is fixedly connected to two sets of I-beams. The surface of each I-beam is slidably connected to two sets of fixed frames. The two fixed frames are fixedly connected to the top surface of the extension plate, and the extension plate supports the hydraulic rods.

[0007] Preferably, the rotating mechanism includes a servo motor fixedly connected inside the motor housing, and the output end of the servo motor is splinedly connected to a transmission rod. The transmission rod is fixedly connected to one side of the material hopper, and the transmission rod facilitates the rotation of the material hopper.

[0008] Preferably, the sealing mechanism includes a sealing plate slidably connected inside the chute. Limiting holes are formed on the surfaces of the sealing plate and the material hopper. A limiting post is inserted into the inside of the limiting hole. A silicone pad is sleeved on the surface of the limiting post. The silicone pad is adapted to the limiting hole to provide a tight connection.

[0009] Preferably, a connecting column is fixedly connected to the back of the material hopper, and a bearing is rotatably connected to one end of the connecting column. The bearing is fixedly connected to the surface of the telescopic frame, and the bearing drives the connecting column on one side to rotate.

[0010] Preferably, two sets of handles are fixedly connected to the surface of one of the telescopic frames, and the surface of the handles is fitted with anti-slip sleeves to facilitate anti-slip.

[0011] Preferably, the bottom of the extension plate is fixedly connected to four sets of casters in a rectangular array, and each of the four casters is equipped with a brake pad for easy braking.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a lifting mechanism and a rotating mechanism, when unloading, the servo motor on one side is started. The servo motor drives the material bucket on one side to rotate to a certain angle, which facilitates the emptying of the material inside the material bucket. This allows for the quick cleaning of coal and mineral materials accumulated at the bottom of the material bucket. In addition, the mine car is also equipped with a lifting mechanism. Activating the hydraulic rod on the surface of the extension plate allows the hydraulic rod to push the telescopic frame on the top to adjust its height on a fixed frame on one side. This causes the material bucket on the telescopic frame to rise and fall together with the telescopic frame. Workers can adjust the height according to their actual needs to accommodate workers of different heights.

[0014] 2. By setting up a sealing mechanism, during material conveying, the sealing plate is aligned with the groove opened on the inner wall of the material hopper, and inserted into the groove to seal the material hopper. Then, a limiting post is inserted into two sets of limiting holes on one side of the material hopper to limit and fix the sealing plate. Since the surface of the limiting post is equipped with a silicone pad, it is elastic and can be tightly connected with the limiting hole, making it difficult to fall off. This avoids the material inside the hopper from spilling out and wasting resources when encountering bumpy sections during the conveying process. Attached Figure Description

A material hopper 6 is fixedly connected to one end of the rotating mechanism 5. A groove is opened on the inner wall of the material hopper 6. A sealing mechanism 7 is slidably connected inside the groove. By setting up the sealing mechanism 7, the material inside the material hopper 6 is prevented from spilling during the transportation process due to bumpy road sections, thus avoiding resource waste.

[0023] The lifting mechanism 3 includes two sets of hydraulic rods 301 fixedly connected to the middle of the surface of the extension plate 2. One end of each hydraulic rod 301 is fixedly connected to a telescopic frame 302. One side of each telescopic frame 302 is fixedly connected to two sets of I-beams 303. The surface of each I-beam 303 is slidably connected to two sets of fixed frames 304. Both fixed frames 304 are fixedly connected to the top surface of the extension plate 2. The extension plate 2 supports the hydraulic rods 301.

[0024] The rotating mechanism 5 includes a servo motor 501 fixedly connected inside the motor housing 4. The output end of the servo motor 501 is splinedly connected to a transmission rod 502. The transmission rod 502 is fixedly connected to one side of the material hopper 6, and the transmission rod 502 facilitates the rotation of the material hopper 6.

[0025] The sealing mechanism 7 includes a sealing plate 701 that is slidably connected inside the chute. Limiting holes are provided on the surfaces of the sealing plate 701 and the material hopper 6. A limiting post 702 is inserted into the inside of the limiting hole. A silicone pad 703 is sleeved on the surface of the limiting post 702. The silicone pad 703 is adapted to the limiting hole to provide a tight connection.

[0026] A connecting column 8 is fixedly connected to the back of the material hopper 6. A bearing 9 is rotatably connected to one end of the connecting column 8.
