Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A valve plate sorting device for gangue sorting includes a support seat 1, a feeding belt 2 is connected to the upper end of the support seat 1, a sorting bin 3 is connected to one side of the support seat 1, a collecting bin 4 is connected to one side of the sorting bin 3, a conveying frame 5 is connected inside the sorting bin 3, a conveying belt 6 is connected to the conveying frame 5, when the gangue on the conveying belt 6 is transported, the gangue is not densely stacked, and the arrangement density of the gangue needs to be controlled to avoid the gangue accumulation causing the shooting accuracy to decrease and affecting the sorting accuracy, and a collecting box 1 is connected to one side of the conveying frame 5 2. The collecting box 12 is arranged in the collecting bin 4, a partition 13 is arranged in the collecting bin 4, a fixing frame 14 is connected to the conveying frame 5, a spray valve frame 15 is connected to the fixing frame 14, a spray valve frame 15 is connected to the spray valve frame 15, a plurality of spray pipes 30 are arranged, and a plurality of spray pipes 30 are closely arranged on the spray valve frame 15, the spray valve frame 15 is connected to a gas tank 10 through a gas pipeline 9, the gas tank 10 is connected to an air compressor 11 through a gas pipeline 9, and an extrusion mechanism for crushing large pieces of coal gangue is connected to the conveying frame 5.

[0025] Specifically, Figure 3 As shown, the conveyor frame 5 is connected with a ray source 7 and an industrial camera 8. The ray source 7 can emit X-rays to cooperate with the industrial camera 8 to capture the distribution of coal gangue on the conveyor belt 6, and then transmit the distribution information to the processing terminal, and then control the corresponding air injection pipe 30 to operate, so as to push the coal gangue into different areas in the collection box 12;

[0026] When sorting coal gangue, the industrial camera 8 and the radiation source 7 work together to accurately determine its distribution on the conveyor belt 6. The industrial camera 8 quickly captures images of coal gangue at a certain frequency. These images are transmitted to the computer image processing system. The algorithm is used to analyze the differences in surface features such as color and texture between coal and gangue, mark their positions and contours, and then output the analysis data such as position and size. The radiation source 7 emits X-rays. Due to the different densities of coal and gangue, the degree of absorption and attenuation of X-rays is different. The detector on the other side receives the X-ray signal after penetration and converts it. The computer processing system reconstructs the internal structure and density distribution image based on this, and analyzes the type, position and other information of coal gangue. The combination of the two data provides a more accurate judgment basis for coal gangue sorting. This technology is a direct reference to the existing technology and will not be elaborated on here.

[0027] Specifically, Figure 4 As shown, the extrusion mechanism includes a lower pressure plate 28, a fixed plate 16 is connected to the conveying frame 5, the fixed plate 16 is connected to the L-shaped plate 24 through a telescopic component, the upper end of the lower pressure plate 28 is connected to a spring 29 and an extrusion rod 26, the upper end of the extrusion rod 26 is connected to an upper pressure plate 27, and the fixed plate 16 is connected to the telescopic cylinder 18 through a cylinder frame 17.

[0028] Specifically, Figure 3 and Figure 4 As shown, the telescopic component includes a symmetrical rod 22, which is slidably connected to the fixed plate 16. A spring 23 is sleeved on the outer side of the symmetrical rod 22, and the spring 23 is connected between the L-shaped plate 24 and the fixed plate 16. By setting the symmetrical rod 22, the stability of the horizontal movement of the L-shaped plate 24 is improved.

[0029] Specifically, Figure 4 As shown, the telescopic end of the telescopic cylinder 18 is connected to a wheel frame 20, and a roller 21 is rotatably connected to the wheel frame 20. By providing the roller 21 structure, the wear caused by mutual contact between the structures can be reduced.

[0030] Specifically, Figure 4 As shown, a pressing rod 25 is connected to one side of the L-shaped plate 24, and a button 19 is connected to one side of the fixed plate 16. When the button 19 structure is pressed, the telescopic cylinder 18 retracts and retracts one back and forth, and the pressing operation of the lower pressing plate 28 is precisely controlled by the pressing rod 25 and the button 19 structure.

[0031] In summary, the present embodiment provides a valve plate sorting device for sorting gangue. When the gangue needs to be sorted, the gangue is transported through the conveyor belt 6. The larger gangue will be blocked by the L-shaped plate 24, while the gangue that meets the volume size will move from under the L-shaped plate 24 along with the conveyor belt 6. When a certain amount of gangue accumulates, the L-shaped plate 24 can be pushed to move, so that the spring 1 23 structure is compressed, driving the pressing rod 25 to press the button 19 structure. The button 19 can control the telescopic cylinder 18 to extend, thereby pressing the upper pressure plate 27 located below the telescopic cylinder 18 downward, so that the spring 29 structure is stretched, and the lower pressure plate 28 is used to squeeze and crush the gangue, so that the large volume of gangue is squeezed to meet the volume size, so as to continue to be transported on the conveyor belt 6.

[0032] When the gangue is moved to below the radiation source 7 and the industrial camera 8, the distribution of the gangue can be captured. Combined with the running speed of the conveyor belt 6, the gangue is moved to the jet pipe 30, and different jet pipes 30 are controlled to jet and blow the gangue. The valve rack 15 is provided at two locations, and the partition plate 13 structure is provided at two locations, which separates the collection box 12 into three areas. When the two jet pipes 30 are operated at the same time, the gangue can be driven to fall into the area in the middle position, thereby achieving the effect of precise sorting.

[0033] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
