[0002] A thermal power plant, also known as a thermal power plant or thermal power station, is a factory that uses combustible materials (such as coal, oil, natural gas, etc.) as fuel to produce electricity. A coal yard is a place where coal is stored, and it is usually an auxiliary facility of a thermal power plant.

[0003] Coal trucks, as the main means of coal transportation, bear the important task of transporting coal from the production site or transfer station to the coal yard. The traditional method of unloading coal is to use a hydraulic system to lift the truck body and tilt it, so that the coal slides out of the truck body by itself. Although this method is efficient, when unloading coal at an angle, especially when the empty cargo box is tilted towards the coal pit or coal pool, the vehicle is prone to instability. This instability may lead to rollover accidents, which pose a serious threat to the driver and the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that vehicles are prone to instability in the center of gravity when using traditional coal unloading methods. This instability may lead to rollover accidents, posing a serious threat to the driver and the surrounding environment. Therefore, this invention proposes a coal unloading device for coal yard vehicles.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a coal unloading device for a coal yard coal transport vehicle, including a coal transport box 1, a movable door 11 movably installed on the surface of the coal transport box 1, a partition 12 fixedly installed on the inner wall of the coal transport box 1, two first motors 2 fixedly installed on one side of the outer wall of the coal transport box 1, and second motors 3 fixedly installed at both the front and rear ends of the coal transport box 1. A first discharge cylinder 4 and a second discharge cylinder 5 are fixedly installed at the bottom of the interior of the coal transport box 1, respectively. The first discharge cylinder 4 and the second discharge cylinder 5 have the same structure. The top of the partition 12 is arc-shaped. The first discharge cylinder 4 and the second discharge cylinder 5 are both installed at the bottom of the partition 12. An opening 121 is opened at the top of the partition 12. A connecting block 13 is fixedly connected to the bottom of the partition 12. The bottom of the connecting block 13 is fixedly connected to the top of the first discharge cylinder 4. The bottom end of the opening 121 communicates with the interior of the first discharge cylinder 4. Spiral blades 21 are fixedly connected to the output ends of the two first motors 2, and the two spiral blades 21 are movably installed inside the first discharge cylinder 4 and the second discharge cylinder 5, respectively.

[0025] In this embodiment, coal is stored in a coal transport box 1 and transported by a coal transport vehicle. The movable door 11 is limited to prevent it from moving. When it is necessary to unload the coal from inside the coal transport box 1, the bottom of the opening 121 is in a flow state, allowing the coal to fall into the first discharge cylinder 4 and the second discharge cylinder 5. The first motor 2 is started to drive the spiral blade 21 to rotate, pushing the coal inside the first discharge cylinder 4 outward, while the coal at the top of the partition 12 gradually flows downward, continuously discharging the coal. The installed second discharge cylinder 5 can improve the coal discharge speed.

[0026] Example 2

[0027] like Figures 1-5 As shown, a baffle 6 is provided at the bottom of the partition 12. The baffle 6 is movably installed at the bottom of the opening 121. One end of the surface of the baffle 6 is movably inserted through the interior of the connecting block 13. A threaded hole 601 is provided on one side of the baffle 6. A screw 31 is fixedly connected to the output end of the second motor 3. The surface of the screw 31 is threadedly connected to the inner wall of the threaded hole 601.

[0028] In this embodiment, when coal is stored inside the coal box, the baffle 6 is located at the bottom of the vertical opening 121, covering the top of the first discharge cylinder 4, preventing coal from flowing into the first discharge cylinder 4. The same applies to the second discharge cylinder 5. When it is necessary to discharge and unload coal, the second motor 3 is started to drive the screw 31 to rotate. The screw 31 rotates inside the threaded hole 601, causing the baffle 6 to move horizontally to one side of the opening 121. At this time, the bottom of the opening 121 is in a flow state, which facilitates the control of coal discharge.

[0029] The working principle of this embodiment is as follows: Coal is stored in the coal conveying box 1. When it is necessary to unload the coal from the coal conveying box 1, the second motor 3 is started to drive the screw 31 to rotate. The screw 31 rotates inside the threaded hole 601, causing the baffle 6 to move horizontally to one side of the opening 121. At this time, the bottom of the opening 121 is in a flow state, and the coal falls into the first discharge cylinder 4 and the second discharge cylinder 5. The first motor 2 is started to drive the spiral blade 21 to rotate, pushing the coal inside the first discharge cylinder 4 outward, while the coal at the top of the baffle 12 gradually flows downward, continuously discharging the coal. The installed second discharge cylinder 5 can improve the coal discharge speed, eliminating the need to tilt the coal conveying box 1 for unloading, thereby improving the safety of the unloading process.
