Description

[0002] Open-pit coal mines refer to coal seams deposited on the surface or shallow layers due to geographical changes, and are mined directly in the open air. Open-pit mining is a process of removing the covering on the ore body to obtain the desired minerals. In the process of open-pit coal mining, stripping the stripping material covering the upper part of the coal seam is a key step in exposing the coal seam. Stripping and dumping refers to the operation of shoveling the stripping material with excavation equipment and stacking it on the side. When the covering layer of the coal seam is not thick and is horizontal or nearly horizontal, the mining process of dumping it into the internal spoil dump can be adopted.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-Figure 3 The present invention provides an open-pit coal mine stripping continuous dumping device, comprising:

[0029] A vehicle body 1, on which a moving component is mounted;

[0030] An anti-fall mechanism, wherein two groups of the anti-fall mechanism are provided, and the two groups of the anti-fall mechanism are symmetrically arranged on both sides of the vehicle body 1, and the anti-fall mechanism comprises a buffer frame 2, and a buffer mechanism is arranged between the buffer frame 2 and the vehicle body 1, and the height of the buffer frame 2 is higher than the height of the moving component;

[0031] A stacking mechanism, the stacking mechanism comprises a crushing box 3 fixedly connected to the top of the vehicle body 1, a mechanical arm 4 is installed on the front side of the crushing box 3, a soil shovel 5 is installed on the end of the mechanical arm 4, and a crusher is installed in the crushing box 3;

[0032] The discharge mechanism includes a conveyor belt 6 installed at the rear end of the vehicle body 1, one end of the conveyor belt 6 extends into the crushing box 3 and is arranged corresponding to the discharge port of the crusher, a screening component is installed at the rear end of the vehicle body 1, one end of the conveyor belt 6 is arranged corresponding to the screening component, and a propulsion component is installed on the screening component.

[0033] When the present invention is working, firstly, the mechanical arm 4 drives the shovel 5 to peel off the coal mine covering, and then the coal mine is mined and put into the crusher in the crushing box 3. The crusher crushes the large pieces of coal and then outputs them to the conveyor belt 6. The crushing box 3 is output through the conveyor belt 6. The conveyor belt 6 transports the coal to the screening component. The screening component separates the lump coal from the fine coal and gravel, and finally pushes it out through the propulsion component to complete the mining operation. During mining, after the mobile component sinks into the soil, the buffer frame 2 cooperates with the buffer component to support the vehicle body 1, and at the same time assists the vehicle body 1 to get out of trouble, ensuring that the vehicle body 1 can continue to operate.

[0034] When the vehicle body 1 of the present invention is stuck in the mud, the buffer frame 2 can cooperate with the buffer assembly to support the vehicle body 1, and at the same time cooperate with the moving assembly to enable the vehicle body 1 to quickly escape, ensuring that the device can operate in different environments.

[0035] A further optimized solution is that the buffer mechanism includes two groups of buffer components, and the two groups of buffer components are symmetrically installed between the buffer frame 2 and the vehicle body 1. The buffer component includes two hinged seats 7, and the two hinged seats 7 are respectively fixed on the buffer frame 2 and the vehicle body 1. A telescopic rod 8 is hinged between the two hinged seats 7, and an angle is set between the telescopic rod 8 and the buffer frame 2. A buffer spring 9 is sleeved on the telescopic rod 8, and both ends of the buffer spring 9 are respectively installed on the two hinged seats 7. A bearing plate 10 is installed at the bottom of the buffer frame 2.

[0036] A further optimized solution is that the screening assembly includes a screening frame 11, a mounting frame 12 is installed at the rear end of the vehicle body 1, the screening frame 11 and the mounting frame 12 are slidingly connected, a screening net 13 is arranged on the screening frame 11, the conveyor belt 6 and the screening net 13 are correspondingly arranged, a supporting frame 14 is installed on the vehicle body 1, a vibration assembly is installed on the supporting frame 14, and the vibration assembly is in contact and cooperation with the screening frame 11.

[0037] A further optimized solution is that the vibration assembly includes a transmission motor 15 fixedly connected to the support frame 14, two groups of rotating shafts are rotatably connected to the support frame 14, and cams 16 are respectively fixedly connected to the two groups of rotating shafts, and a mounting arm 17 is fixedly connected to the screening frame 11, and a pulley 18 is rotatably connected to the end of the mounting arm 17, and the pulley 18 is in contact with the cam 16, and a first driven pulley 19 is fixedly connected to the rotating shaft, and the two first driven pulleys 19 are driven and matched by a first belt 20, and the output shaft of the transmission motor 15 is fixedly connected to a driving pulley, and the driving pulley and one of the first driven pulleys 19 are driven and matched by a second belt 21, and the other first driven pulley 19 is driven and matched with the propulsion assembly; a reset spring 22 is installed between the top surface of the screening frame 11 and the top surface of the buffer frame 2.

[0038] A further optimized solution is that the propulsion assembly includes a roller 23 rotatably connected to the vehicle body 1 through a connecting shaft, the roller 23 is located above the screening net 13, and the two rollers 23 are coupled through a transmission belt. A second driven pulley 24 is fixedly connected to one of the connecting shafts, and the second driven pulley 24 and the first driven pulley 19 are coupled through a third belt 25. A plurality of push plates 26 are fixedly connected to the outer wall of the transmission belt, and intervals are provided between the plurality of push plates 26, and intervals are provided between the push plates 26 and the top surface of the screening net 13.

[0039] According to a further optimization scheme, a slide rail 27 is fixedly connected to the screening frame 11 , a slider 28 is fixedly connected to the mounting frame 12 , and the slider 28 is slidably connected to the slide rail 27 .

[0040] The transmission motor 15 outputs the transmission force, which drives the rotating shaft to rotate, thereby driving the cam 16 on the rotating shaft to rotate. The rotation of the cam 16 causes the pulley 18 to slide along the outer edge surface of the cam 16, thereby causing the entire screening frame 11 to move up and down. At the same time, the setting of the buffer spring 9 allows the screening frame 11 to be quickly lowered after being raised, thereby forming a vibration effect, so that the sparse coal mine and gravel can be screened out, and the coal blocks with larger particles are retained. After that, the roller rotates under the action of the third belt 25, thereby driving the transmission belt to drive, and the coal blocks on the screening net 13 are pushed down by the push plate 26 on the transmission belt to complete the screening. This can reduce the difficulty of subsequent screening and improve the scope of application of the device.

[0041] A further optimized solution is that the moving component includes four groups of moving wheels 29 symmetrically arranged in pairs, and the moving wheels 29 are rotatably connected to the opposite sides of the vehicle body 1 through a mounting shaft, a driven sprocket is fixedly connected to the mounting shaft, a driving motor 30 is fixedly connected to the vehicle body 1, and an output shaft of the driving motor 30 is fixedly connected to a driving sprocket, and the driving sprocket and the driven sprocket are matched through a chain transmission.

[0042] According to a further optimization scheme, a mounting seat 31 is fixedly connected to the top of the buffer frame 2, a long hole is vertically opened on the mounting seat 31, and the mounting shaft is slidably connected in the long hole.

[0043] By setting the mounting seat 31, the moving wheel 29 and the mounting frame 12 can form a whole. At the same time, the setting of the long hole can enable the buffer frame 2 to move a certain distance relative to the moving wheel 29. In this way, when the moving wheel 29 sinks into the mud, the buffer frame 2 will contact the ground to support the entire vehicle body 1 to prevent the vehicle body 1 from continuing to sink. At the same time, the driving motor 30 outputs a strong torque to drive the moving wheel 29 to rotate to get out of trouble. Since part of the soil will be thrown out during the rotation process, a relative misalignment occurs between the moving wheel 29 and the buffer frame 2 at this time, and the moving wheel 29 can continue to move downward, and the buffer frame 2 will not sink into the mud due to the lack of support for the moving wheel 29. At the same time, the buffer frame 2 in this embodiment is set as a ship-shaped structure, that is, the front and rear ends are tilted upward, so as to avoid hitting obstacles during movement and causing the device to be unable to move.

[0045] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
