DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1-5The utility model provides an embodiment: a gangue sorting device, comprising a feed port 1 and a first gangue sorting mechanism 3, a first transmission channel assembly 2 is arranged below the feed port 1, one end of the first transmission channel assembly 2 is connected to the first gangue sorting mechanism 3, the first gangue sorting mechanism 3 comprises a gangue sorting bin 301, an external motor 302, a rotating shaft 303, a rotating plate 304, a screen 305 and a gangue sorting collection bin 306, one end of the first transmission channel assembly 2 is connected to the gangue sorting bin 301, an external motor 302 is arranged above the gangue sorting bin 301, and the output end of the external motor 302 is fixed A rotating shaft 303 is provided, a rotating plate 304 is provided on the side of the rotating shaft 303, a gangue sorting and collecting bin 306 is provided below the gangue sorting bin 301, a screen 305 is provided between the gangue sorting bin 301 and the gangue sorting and collecting bin 306, the gangue sorting bin 301 is connected with the second transmission channel 5 through the first connecting pipe 4, the second transmission channel 5 is connected with the second gangue sorting part 6, the second gangue sorting part 6 is connected with the third transmission channel 8 through the second connecting pipe 7, the third transmission channel 8 is connected with the third gangue sorting part 9, and a discharge port 10 is provided at one end of the third gangue sorting part 9.

[0023] The first conveying channel assembly 2 includes a conveying channel 201, a transmission body 202, a conveyor belt 203, a connecting shaft 204, a paddle 205, a torsion spring 206 and a collecting channel 207. The conveying channel 201 is arranged below the feed port 1. The conveying channel 201 is arranged in an inclined manner. The transmission body 202 is arranged at the bottom of the conveying channel 201. The conveyor belt 203 is arranged inside the conveying channel 201. The connecting shafts 204 on both sides of the conveyor belt 203 are installed on the conveying channel 201. A paddle 205 is connected to the circumferential surface of the shaft 204, and a torsion spring 206 is connected between the connecting shaft 204 and the paddle 205. A collecting channel 207 is provided at the end of the conveying channel 201 away from the feed port 1. After the gangue is accumulated in the conveying channel 201, the paddles 205 on both sides swing at the same time to make the conveying height of the gangue tend to be flat, thereby controlling the capacity of the feeding gangue sorting bin 301 and preventing a large amount of gangue from moving too fast and suddenly entering the gangue sorting bin 301, resulting in insufficient sorting.

[0024] The conveyor belt 203 is rotatably connected with the conveying channel 201 through the transmission body 202, the collecting channel 207 is connected with the conveying channel 201, and the gangue sorting bin 301 is connected with the collecting channel 207. Under the operation of the conveyor belt 203, the gangue raw material moves in the conveying channel 201 toward the gangue sorting bin 301, and the internal structure of the collecting channel 207 gradually narrows from the conveying channel 201 to the gangue sorting bin 301, so that the gangue entering the gangue sorting bin 301 is less stacked, which is convenient for timely separation of corresponding particle sizes in the upper layer of gangue, thereby improving the accuracy of classification.

[0025] The paddle 205 forms a rotating structure with the transmission channel 201 through the connecting shaft 204. The paddle 205 and the connecting shaft 204 are evenly distributed on both sides of the transmission channel 201. When the transmission of coal gangue is stacked at some positions, the coal gangue height touches the position of the paddle 205. During transmission, under the action of the torsion spring 206, the coal gangue pushes each group of paddles 205 to swing, clearing the movement of the coal gangue, maintaining a uniform flow of coal gangue, and preventing the accumulation of coal gangue from blocking the channel and affecting normal work.

[0026] The output end of the external motor 302 is fixedly connected to the rotating shaft 303, the body of the external motor 302 is fixedly connected to the top cover of the coal gangue sorting bin 301, the rotating shaft 303 passes through the screen 305, and two groups of rotating plates 304 are provided. The rotating plates 304 are respectively fixed on the rotating shaft 303 above and below the screen 305. The rotating plates 304 form a rotating structure with the coal gangue sorting bin 301 through the rotating shaft 303. The external motor 302 drives the rotating plates 304 to rotate, and the coal gangue in the coal gangue sorting bin 301 is continuously disrupted in a cycle, so that the coal gangue of the required particle size can be separated quickly and with high sorting accuracy, thereby improving the sorting efficiency.

[0027] The screen 305 is connected to the gangue sorting bin 301 by a slot, and the rotating plate 304 forms a rotating structure with the gangue sorting and collecting bin 306 through the rotating shaft 303. The gangue in the gangue sorting bin 301 passes through the hole position of the screen 305, and the gangue corresponding to the hole size smaller than the hole size will fall into the gangue sorting and collecting bin 306 below. The rotating plate 304 below rotates simultaneously with the rotating plate 304, and the gangue separated in the gangue sorting and collecting bin 306 is gathered and pushed to the exit position to complete the classification of the gangue.

[0028] There is a one-to-one correspondence between the second conveying channel 5 and the third conveying channel 8 and the first conveying channel assembly 2, and there is a one-to-one correspondence between the second gangue sorting part 6 and the third gangue sorting part 9 and the first gangue sorting mechanism 3. The apertures of the screens 305 of the first gangue sorting mechanism 3, the second gangue sorting part 6 and the third gangue sorting part 9 are 2 mm, 4 mm and 8 mm respectively. Gangue with a particle size of 1-2 mm is obtained through the first conveying channel assembly 2 and the first gangue sorting mechanism 3, gangue with a particle size of 2-4 mm is obtained through the second conveying channel 5 and the second gangue sorting part 6, and gangue with a particle size of 4-8 mm is obtained through the third conveying channel 8 and the third gangue sorting part 9, thereby classifying gangue raw materials with particle sizes that meet the technical requirements of artificial soil, ensuring that raw materials with different particle sizes give full play to different physical properties.

[0029] Working principle: The crushed gangue to be sorted is added to the device from the feed port 1. Under the operation of the conveyor belt 203, the gangue raw materials move in the conveying channel 201 toward the gangue sorting bin 301. When the gangue is stacked at some positions during the transmission process, the gangue height touches the position of the paddle 205. Under the action of the torsion spring 206, the gangue pushes each group of paddles 205 to swing, and the gangue transmission height tends to be flat, which dredges the movement of the gangue, maintains a uniform flow of the gangue, and prevents the accumulation of gangue from blocking the channel and affecting normal work, thereby controlling the capacity of the feeding gangue sorting bin 301 at the same time, and preventing a large amount of gangue from moving too fast and suddenly entering the gangue sorting bin 301, resulting in insufficient sorting. The internal structure of the collecting channel 207 gradually narrows from the conveying channel 201 to the gangue sorting bin 301, so that the gangue entering the gangue sorting bin 301 is less stacked, which facilitates the timely separation of corresponding particle sizes in the upper layer of gangue and improves the accuracy of classification. The external motor 302 drives the rotating plate 304 to rotate, and cyclically disrupts the gangue in the gangue sorting bin 301, so that the gangue of the required particle size can be separated quickly and with high sorting accuracy, thereby improving the sorting efficiency. The gangue in the gangue sorting bin 301 passes through the hole position of the screen 305, and the gangue corresponding to the hole size smaller than the hole size will fall into the gangue sorting and collecting bin 306 below. The rotating plate 304 below rotates simultaneously with the rotating plate 304, and the gangue separated in the gangue sorting and collecting bin 306 is gathered and pushed to the exit position. The unseparated gangue in the gangue sorting bin 301 enters the next level of sorting operation, and the same steps are performed through the second transmission channel 5 and the second gangue sorting part 6 as well as the third transmission channel 8 and the third gangue sorting part 9, and finally the classification of the gangue is completed. Gangue with a particle size of 1-2 mm is obtained through the first conveying channel component 2 and the first gangue sorting mechanism 3, gangue with a particle size of 2-4 mm is obtained through the second conveying channel 5 and the second gangue sorting part 6, and gangue with a particle size of 4-8 mm is obtained through the third conveying channel 8 and the third gangue sorting part 9. Gangue exceeding the maximum particle size of sorting is collected from the discharge port 10, thereby classifying the gangue raw materials with particle sizes that meet the technical requirements of artificial soil, ensuring that raw materials with different particle sizes give full play to different physical properties.
