Description

Technical Field

[0001] This utility model belongs to the field of coal mine production technology, and in particular relates to a coal mine mining and transportation device. Background Technology

[0002] In coal mines, due to the confined internal space, the main mode of coal transportation is small mine cars. To adapt to the narrow underground tunnels, compact size, simple structure, stability, and ease of maneuverability are fundamental attributes of mine cars. To simplify the car structure and improve transportation efficiency, it is necessary to enhance the efficiency of unloading coal and the ease of operation. Most existing mine cars use a tipping bucket structure, but the buckets lack covers, making it easy for coal to spill. Furthermore, during unloading, the large load requires significant pressure, making operation inconvenient and posing certain safety hazards. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a coal mining and transportation device to solve the problems of easy coal spillage and inconvenient coal unloading.

[0004] The technical solution to the technical problem is as follows: The vehicle body has a support plate on top, and a hopper is fixed to the upper part of the support plate. The vehicle body is rotatably connected to a rotating shaft arranged in the front-rear direction. Multiple cams are coaxially fixed to the rotating shaft, and the cams contact the bottom surface of the support plate. A first gear and a second gear are rotatably connected to the front end of the hopper, and the first and second gears mesh externally. A first lever is fixed to the front end of the first gear, and a first cover plate is fixed to the upper end of the first lever. A second lever is fixed to the front end of the second gear, and a second cover plate is fixed to the upper end of the second lever. A hopper door is hinged to both the left and right sides of the hopper. Hydraulic rods located on the front and rear sides of the hopper door are hinged to the support plate, and the other end of the hydraulic rods is hinged to the hopper door.

[0005] Preferably, both the first cover plate and the second cover plate are arc-shaped plates.

[0006] Preferably, a first motor is installed on the hopper, and the first motor is fixedly connected to a first gear via a reducer.

[0007] Preferably, the left and right ends of the hopper are rotatably connected to rollers, and the first cover plate and the second cover plate swing on their respective rollers.

[0008] Preferably, the vehicle body is fixed with guide posts located around the support plate, the support plate slides up and down inside the guide posts, and a spring is sleeved on the guide posts, with the spring located between the vehicle body and the support plate.

[0009] Preferably, a second motor is installed on the vehicle body, and the second motor is coaxially and fixedly connected to the rotating shaft.

[0010] This invention offers the following advantages over traditional equipment: The linkage between the first and second cover plates allows them to open and close simultaneously, facilitating coal loading into the silo and preventing coal spillage, thus improving transportation safety. The double-sided silo door design, combined with a cam-driven vibrating silo, significantly enhances unloading efficiency. The ingenious structure, high degree of automation, simple operation, and practicality make it highly convenient and practical. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 3 A coal mining and transportation device is provided, comprising a vehicle body 1, a support plate 2 on the top of the vehicle body 1, a hopper 3 fixed at the upper end of the support plate 2, a rotating shaft 4 arranged in the front-rear direction connected to the vehicle body 1, a plurality of cams 5 coaxially fixed to the rotating shaft 4, the cams 5 contacting the bottom surface of the support plate 2, a first gear 6 and a second gear 7 rotatably connected to the front end of the hopper 3, the first gear 6 and the second gear 7 meshing externally, a first lever 8 fixed to the front end of the first gear 6, a first cover plate 9 fixed to the upper end of the first lever 8, a second lever 10 fixed to the front end of the second gear 7, a second cover plate 11 fixed to the upper end of the second lever 10, and hopper doors 12 hinged to both the left and right sides of the hopper 3, hydraulic rods 13 located on the front and rear sides of the hopper doors 12 hinged to the support plate 2, the other end of the hydraulic rods 13 hinged to the hopper doors 12.

[0015] To facilitate the swinging of the first cover plate 9 and the second cover plate 11, both the first cover plate 9 and the second cover plate 11 are arc-shaped plates.

[0016] The hopper 3 is equipped with a first motor 14, which is fixedly connected to the first gear 6 via a reducer.

[0017] To ensure the stability of the left and right swing of the first cover plate 9 and the second cover plate 11, rollers 15 are rotatably connected to the left and right ends of the hopper 3, and the first cover plate 9 and the second cover plate 11 swing on their respective rollers 15.

[0018] The vehicle body 1 is fixed with guide posts 16 located around the support plate 2. The support plate 2 slides up and down inside the guide posts 16. A spring 17 is sleeved on the guide posts 16 and the spring 17 is located between the vehicle body 1 and the support plate 2.

[0019] A second motor 18 is installed on the vehicle body 1, and the second motor 18 is coaxially and fixedly connected to the rotating shaft 4.

[0020] When this utility model is in use, the first motor 14 is started, which drives the first gear 6 to rotate. The first gear 6 meshes with the second gear 7. The first lever 8 and the second lever 10 are symmetrical. The first gear 6 drives the second gear 7 to rotate. The first lever 8 drives the first cover plate 9 to swing outward on the right roller 15. The second lever 10 drives the second cover plate 11 to swing outward on the left roller 15. The first cover plate 9 and the second cover plate 11 open simultaneously, with good linkage. When the first cover plate 9 and the second cover plate 11 are fully open, the silo door 12 is closed under the action of the hydraulic rod 13. At this time, the mined coal is poured into the silo 3. After the silo 3 is loaded, the first motor 14 is reversed, the first gear 6 and the second gear 7 are reset, and the first cover plate 9 and the second cover plate 11 move towards the middle of the silo 3 at the same time. Then, the first cover plate 9 and the second cover plate 11 cover the top of the silo 3, and the top of the silo 3 is closed, which prevents coal from spilling and dust from being generated during the transportation of coal in the silo 3, thus ensuring good safety. The vehicle body 1 is started, transporting the support plate 2 and the hopper 3 to a suitable work position. When the hopper 3 needs to be unloaded, the hydraulic rod 13 is activated, and the hopper door 12 is hinged to the hopper 3. The upper end of the hydraulic rod 13 is hinged to the hopper door 12, and the lower end of the hydraulic rod 13 is hinged to the support plate 2. Depending on the actual needs, the left or right hopper door 12 can be opened individually, or both hopper doors 12 can be opened simultaneously. Taking the simultaneous opening of the left and right hopper doors 12 as an example, the hydraulic rod 13 extends outward, the hopper door 12 opens outward, and the coal in the hopper 3 flows outward. At this time, the second motor 18 is started, and the second motor 18 drives the rotating shaft 4 to rotate. Multiple cams 5 rotate simultaneously. The protrusions of cams 5 drive the support plate 2 to move upward along the guide column 16. The spring 17 is in a stretched state. As the protrusions of cams 5 move away from the support plate 2, the support plate 2 moves downward along the guide column 16 under the action of the spring 17. In turn, the support plate 2 drives the silo 3 to vibrate up and down as a whole. The inner bottom surface of the silo 3 is an inclined surface, with the middle being higher and the two sides being lower. This helps the coal in the silo 3 to flow outward, saving time and effort, and improving the coal unloading efficiency. This increases the turnover rate of the silo 3 and thus improves the transportation efficiency. After the coal is unloaded, the hydraulic rod 13 resets, and the silo door 12 is in a closed state. This cycle repeats.

[0021] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
