[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a unloading device for coal transportation, comprising: Base 1; Automatic unloading mechanism 2 is installed on the top of base 1 and is used to continuously unload coal. The auxiliary unloading mechanism 3 is installed on the automatic unloading mechanism 2 and is used to improve the smoothness of unloading. The automatic unloading mechanism 2 includes a cargo box 21. A drive motor 22 is fixedly installed on the back of the cargo box 21. A screw shaft 23 is rotatably connected to the inner wall of the cargo box 21. The output shaft of the drive motor 22 is fixedly connected to the end of the screw shaft 23. An output cylinder 24 is fixedly connected to the front of the cargo box 21. The end of the screw shaft 23 away from the drive motor 22 extends into the inner cavity of the output cylinder 24. In use, coal is loaded into the inner cavity of the cargo box 21 for transportation. When unloading the coal, controlling the drive motor 22 to work can drive the screw shaft 23 to rotate, thereby continuously pushing the coal inside the cargo box 21 out. The coal can be directly introduced to the place of use through external equipment such as a conveyor belt, without the need for the coal to be reused. It is more suitable for small and medium-sized, multi-batch operations.

[0017] As one implementation method in this embodiment, such as Figure 2 As shown, a connecting arm is rotatably connected to the outer wall of the output cylinder 24, and a cover plate 25 is fixedly installed at the end of the connecting arm. The cover plate 25 is movably abutted against the end of the output cylinder 24. The cover plate 25 is closed at the end of the output cylinder 24 by the rotation of the connecting arm. When unloading coal, the cover plate 25 can be rotated to open. The cover plate 25 is subjected to less pressure from the coal, so the opening operation during unloading is safer than opening the box door.

[0018] As one implementation method in this embodiment, such as Figure 2 As shown, a connecting block 26 is fixedly installed on the outer wall of the cover plate 25, and a connecting block 27 is fixedly installed on the outer wall of the output cylinder 24. A connecting pin 28 is movably inserted into the top of the connecting block 26 and the connecting block 27. In the initial state, the connecting pin 28 is inserted into the interior of the connecting block 26 and the connecting block 27, locking the cover plate 25 closed on the output cylinder 24. When the connecting pin 28 is pulled out from the top of the connecting block 27, the cover plate 25 can be rotated and opened.

[0019] As one implementation method in this embodiment, such as Figure 3 As shown, the automatic unloading mechanism 2 also includes a support base 211 and a frame 213. The support base 211 is fixedly installed on the top of the base 1. A rotating component 212 is rotatably connected to the inner wall of the support base 211. The cargo box 21 is fixedly installed at the end of the rotating component 212. Through the design of the support base 211 and the rotating component 212, the cargo box 21 is rotatably connected to the top of the base 1, which facilitates the subsequent tilting adjustment of the cargo box 21.

[0020] As one implementation method in this embodiment, such as Figure 3 As shown, frame 213 is fixedly installed on the top of base 1. Hydraulic cylinder 214 is rotatably connected to the inner wall of frame 213. Support block 215 is fixedly installed on the telescopic end of hydraulic cylinder 214. Support block 215 is rotatably connected to the outer wall of cargo box 21. One end of hydraulic cylinder 214 is rotatably connected to base 1, and the other end is rotatably connected to cargo box 21. Controlling hydraulic cylinder 214 to extend can make cargo box 21 tilt and rotate to the right, so that the coal inside cargo box 21 can move to screw shaft 23 and then be pushed out.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, the auxiliary unloading mechanism 3 includes a movable plate base 31. An electromagnet 32 ​​is fixedly installed on the inner wall of the movable plate base 31. The movable plate base 31 and the electromagnet 32 ​​are movably connected to the outer wall of the cargo box 21. A first handle 33 is fixedly installed on the outer wall of the movable plate base 31. A first switch 34 is fixedly installed on the first handle 33. The first switch 34 is used to control the on and off of the electromagnet 32. When the electromagnet 32 ​​is energized, it can generate magnetic force. At this time, the electromagnet 32 ​​can be magnetically connected to the outer wall of the cargo box 21. When the electromagnet 32 ​​is turned off, the movable plate base 31 can be completely removed from the cargo box 21. The auxiliary unloading mechanism 3 is set at the unloading point. For multiple sets of bases 1 and automatic unloading mechanisms 2, one set of auxiliary unloading mechanism 3 is sufficient.

[0022] As one implementation method in this embodiment, such as Figure 4As shown, a vibratory motor 35 is fixedly installed on the outer wall of the movable plate base 31. A second handle 36 is also fixedly installed on the outer wall of the movable plate base 31, and a second switch 37 is fixedly installed on the second handle 36. The second switch 37 is used to control the opening and closing of the vibratory motor 35. If coal adheres to the inner wall of the cargo box 21, an electromagnet 32 ​​can be installed on the outer wall of the cargo box 21, and then the vibratory motor 35 can be turned on, which can drive the entire cargo box 21 to vibrate, causing the coal to fall off the inner wall of the cargo box 21 and improving the smoothness of discharge. The electromagnet 32 ​​and the vibratory motor 35 are powered by a power cord connected to a socket. It is worth noting that the electromagnet 32 ​​and the vibratory motor 35 in this solution are... The equipment available to those skilled in the art is not structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0023] Working principle: During use, coal is loaded into the inner cavity of the cargo box 21 for transportation. When unloading the coal, the connecting pin 28 is pulled out from the top of the connecting block 27, and the cover plate 25 is rotated and opened. The drive motor 22 is controlled to drive the screw shaft 23 to rotate, which in turn pushes the coal inside the cargo box 21 out continuously. The coal can be directly introduced to the place of use through external equipment such as a conveyor belt. The hydraulic cylinder 214 is controlled to extend, which makes the cargo box 21 tilt and rotate to the right, so that the coal inside the cargo box 21 can move to the screw shaft 23 and then be pushed out. If the coal is attached to the inner wall of the cargo box 21, the electromagnet 32 ​​can be energized and magnetically attracted to the outer wall of the cargo box 21. Then the vibration motor 35 is controlled to start, which can drive the entire cargo box 21 to vibrate, causing the coal to fall off the inner wall of the cargo box 21 and improving the smoothness of discharge.
