Abstract
Description
Technical Field
[0001] This utility model relates to the field of transport vehicle technology, and in particular to an automatic dumping transport vehicle for mining. Background Technology
[0002] Automatic dump trucks are special transport vehicles equipped with automatic unloading capabilities. They are commonly used in industries such as construction, mining, and logistics. They can complete unloading operations quickly and conveniently, significantly saving unloading time and improving transportation efficiency compared to traditional methods that rely on manual unloading or other mechanical assistance. For example, in mine construction, automatic dump trucks are used to transport materials such as sand and gravel. The vehicle can complete unloading within minutes of arriving at the unloading point and then quickly return to the loading point to continue transporting materials, ensuring the progress of construction.
[0003] One of the core advantages of traditional automated dump trucks for mining is their ability to carry large amounts of ore and their low cost, making them easy to mass-produce. However, traditional automated dump trucks for mining cannot freely control the tilt angle of the hopper, which makes them unable to adapt to different unloading scenarios and reduces the overall operational flexibility. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an automatic dumping transport vehicle for mines, which aims to improve the problem that traditional automatic dumping transport vehicles for mines cannot freely control the tilt angle of the funnel, thus reducing the flexibility of use.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An automatic unloading transport vehicle for mining includes a transport vehicle body. A fixed plate is fixedly connected to the upper surface of the transport vehicle body. A motor is fixedly connected to the upper surface of the fixed plate. A first gear is provided at the output end of the motor. A second gear is meshed with the tooth end of the first gear. A first fixed column is rotatably connected to the inner wall of the second gear. A toothed plate is meshed with the tooth end of the first gear. A support plate is slidably connected to the outer wall of the toothed plate. A top plate is fixedly connected to the upper surface of the toothed plate. A first collar is fixedly connected to the upper surface of the top plate. A first support frame is provided on the inner wall of the first collar. A funnel is fixedly connected to the outer wall of the first support frame. A second collar is fixedly connected to the lower surface of the funnel. A second support frame is slidably connected to the inner wall of the second collar. A support assembly is provided on the upper surface of the transport vehicle body. The support assembly is used to support the sliding column.
[0007] Preferably, the support assembly includes a second fixed column, the lower surface of which is fixedly connected to the upper surface of the transport vehicle body, and a damping shell is fixedly connected to the outer wall of the second fixed column.
[0008] Preferably, a sliding column is provided on the lower surface of the funnel, the outer wall of the sliding column is slidably connected to the inner wall of the damping shell, a spring is provided on the lower surface of the sliding column, the outer wall of the spring is provided on the upper surface of the second fixed column, and the outer wall of the spring is provided inside the damping shell.
[0009] Preferably, the outer wall of the transport vehicle body is provided with indicator lights, and the outer wall of the transport vehicle body is provided with a toolbox.
[0010] Preferably, the outer wall of the motor is provided with a ratchet, the outer wall of the ratchet is provided with a pawl, and the inner wall of the pawl is rotatably connected to the outer wall of the fixed plate.
[0011] Preferably, the lower surface of the support plate is fixedly connected to the upper surface of the fixing plate.
[0012] Preferably, the upper surface of the transport vehicle body is fixedly connected to the lower surface of the second support frame.
[0013] Preferably, the outer wall of the first fixing column is fixedly connected to the inner wall of the fixing plate, and the tooth end of the second gear is meshed with the outer wall of the gear plate.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the first gear is driven to rotate by the motor, which in turn drives the second gear to rotate. When the first and second gears rotate, they drive the toothed plate to move up and down, which in turn drives the top plate to move up and down. When the top plate moves up and down, it drives the first collar to move up and down, which in turn drives the first support frame to move. The first support frame then drives the funnel to rotate on the outer wall of the second support frame. When the funnel is tilted to a suitable angle, the pawl is rotated, which restricts the rotation of the ratchet, thereby controlling the tilt angle of the funnel so that it can adapt to different working scenarios and improve its flexibility of use.
[0016] 2. In this utility model, when the funnel finishes unloading the goods and falls, it will first contact the sliding column and drive the sliding column to slide on the inner wall of the damping shell. When the sliding column slides, it will cooperate with the second fixed column to compress the spring, thereby achieving the effect of buffering the funnel when it falls and preventing damage to the transport vehicle due to excessive impact force when it falls.

[0026] Specifically, when motor 3 is turned on, the first gear 6 is driven to rotate by the fixed action of the output end of motor 3 and the first gear 6. When the first gear 6 rotates, it drives the second gear 7 to rotate. When the first gear 6 and the second gear 7 rotate, they drive the toothed plate 9 to move up and down. The toothed plate 9 is fixed to the top plate 11, which in turn drives the top plate 11 to move up and down. The top plate 11 is fixed to the first collar 12, which in turn drives the first collar 12 to move up and down. When the first collar 12 moves up and down, it drives the first support frame 13 to move. The first support frame 13 is fixed to the funnel 20, which drives the funnel 20 to rotate on the outer wall of the second support frame 19 through the second collar 18, thus achieving the effect of tipping over goods. The ratchet 4 is driven to rotate by the fixed action of the output end of motor 3 and the ratchet 4. The pawl 5 is used to limit the rotation of the ratchet 4, thereby achieving the effect of controlling the tilt angle of the funnel 20.
[0027] Reference Figure 1 , Figure 4 and Figure 5 The support assembly includes a second fixed column 15, the lower surface of which is fixedly connected to the upper surface of the transport vehicle body 1, and a damping shell 16 fixedly connected to the outer wall of the second fixed column 15; a sliding column 14 is provided on the lower surface of the funnel 20, the outer wall of which is slidably connected to the inner wall of the damping shell 16, a spring 17 is provided on the lower surface of the sliding column 14, the outer wall of which is provided on the upper surface of the second fixed column 15, and the outer wall of which is located inside the damping shell 16; an indicator light 21 is provided on the outer wall of the transport vehicle body 1, and a toolbox 22 is provided on the outer wall of the transport vehicle body 1; a ratchet 4 is provided on the outer wall of the motor 3, a pawl 5 is provided on the outer wall of the ratchet 4, and the inner wall of the pawl 5 is rotatably connected to the outer wall of the fixed plate 2;
[0028] Specifically, when the funnel 20 falls, it will first drive the sliding column 14 to slide on the inner wall of the damping shell 16. When the sliding column 14 slides, it will cooperate with the second fixed column 15 to compress the spring 17, thereby achieving a buffering effect on the funnel 20 when it falls.

[0031] Working principle: When the automatic unloading transport vehicle for mining is needed, first turn on motor 3. Motor 3 will drive ratchet 4 and first gear 6 to rotate. When first gear 6 rotates, it will drive second gear 7 to rotate. When first gear 6 and second gear 7 rotate, they will drive toothed plate 9 to move up and down on the inner wall of support plate 10. When toothed plate 9 moves up and down, it will drive top plate 11 to move up and down. When top plate 11 moves up and down, it will drive first collar 12 to move up and down. When first collar 12 moves up and down, it will drive first support frame 13 to move up and down. When first support frame 13 moves, it will drive hopper 20 through second collar 1... 8 rotates on the outer wall of the second support frame 19. The pawl 5 is used to control the rotation of the ratchet 4, thereby achieving the effect of unloading goods and controlling the tilt angle of the funnel 20. When the funnel 20 falls, it first contacts the sliding column 14. When the sliding column 14 slides, it will cooperate with the second fixed column 15 to compress the spring 17, thereby achieving a certain buffering effect on the funnel 20 when it falls. Finally, the automatic dumping transport vehicle for mining can not only control the tilt angle of the funnel 20 through the pawl 5, but also buffer the funnel 20 through the sliding column 14, preventing the funnel 20 from being damaged by the excessive impact force when it falls.
