[0020] A mining gravel sorting device, please refer to Figures 1-5, including a machine body 1. There is a feeding port 2 opened at the upper right side of the machine body 1. There is a primary crushing mechanism provided at the upper right side inside the machine body 1. The primary crushing mechanism includes two front and rear crushing rolls I 4 rotatably connected to the upper right side inside the machine body 1 through a rotating shaft 41. The two rotating shafts 41 are connected by gear transmission. There is a motor I 3 installed at the upper left side inside the machine body 1. The output shaft of the motor I 3 is connected to the rear rotating shaft 41. The motor I 3 is separated by a partition in the crushing chamber outside the machine body 1 to prevent the motor I 3 from being damaged by crushed stones. There is a secondary crushing mechanism provided at the lower left side inside the machine body 1. The secondary crushing mechanism includes two front and rear crushing rolls II 13 rotatably connected to the lower left side inside the machine body 1. The two crushing rolls II 13 are connected by gear transmission. There is a motor II 14 installed on the left outer wall of the machine body 1. The output shaft of the motor II 14 is connected to the rear crushing roll II 13. There is a screen I 5 that can move up and down slidably connected to the inside of the machine body 1 through a chute. The screen I 5 is located below the crushing roll I 4 and is located above the right of the crushing roll II 13. There is a pushing component provided between the front rotating shaft 41 and the screen I 5 for pushing the screen I 5 to vibrate up and down. The pushing component includes a connecting rod 11 connected to the right side of the screen I 5. The connecting rod 11 is slidably connected to the machine body 1. There are two front and rear springs 10 connected between the connecting rod 11 and the machine body 1. The top of the connecting rod 11 is connected to a toothed frame 8. The right end of the front rotating shaft 41 is connected to a missing gear 9. The rotation of the missing gear 9 can engage with the teeth inside the toothed frame 8. There is an electric push rod 6 installed on the right outer wall of the machine body 1. The telescopic rod of the electric push rod 6 extends into the machine body 1 and is connected to a push plate 7. The push plate 7 is located above the screen I 5 and contacts the screen I 5. There is a conveyor belt I 12 provided at the upper right side of the machine body 1 for conveying crushed stones to the right. The conveyor belt I 12 is located below the screen I 5. The left side of the machine body 1 is connected to a collection box 16. The collection box 16 is located at the lower left of the crushing roll II 13. The collection box 16 is composed of an outer box and an inner box. The outer box is fixedly connected to the left side of the machine body 1. Both the left and right sides of the outer box are open. There is an inner box that can be pulled out to the left inside the outer box. The right side and the top of the inner box are both open. The left side of the inner box is connected to a handle. There is a screen II 15 installed inside the machine body 1. The screen II 15 is located below the crushing roll II 13. The screen II 15 is installed in an inclined manner with the left side lower and the right side higher to guide the crushed stones larger than its screen holes into the inner box on the collection box 16 to prevent the crushed stones from staying on the screen II 15 and blocking the screen II 15. There is a conveyor belt II 17 provided at the lower left side of the machine body 1 for conveying crushed stones to the left. The conveyor belt II 17 is located below the screen II 15.
[0021] The crushed stones to be sorted are put into the machine body 1 through the feed inlet 2. The motor I 3 works to drive the rear rotating shaft 41 to rotate. Through the gears on the rotating shaft 41, the front and rear rotating shafts 41 drive the front and rear first crushing rollers 4 to rotate towards each other to initially crush the crushed stones. The crushed stones after the initial crushing fall onto the first screen 5 for screening. The crushed stones smaller than the screen holes of the first screen 5 fall onto the first conveyor belt 12 and are conveyed to the right by the first conveyor belt 12. The crushed stones larger than the screen holes of the first screen 5 stay on the first screen 5. When the telescopic rod of the electric push rod 6 extends, it can push the push plate 7 to move leftward to push the crushed stones remaining on the first screen 5 to the upper part of the second crushing roller 13. The crushed stones then fall onto the second crushing roller 13. The motor II 14 works to drive the rear second crushing roller 13 to rotate. Through the gears on the second crushing roller 13, the front and rear second crushing rollers 13 rotate towards each other to crush the crushed stones for the second time. The crushed stones after the second crushing fall onto the second screen 15 for screening. The crushed stones smaller than the screen holes of the second screen 15 fall onto the second conveyor belt 17 and are conveyed to the left by the second conveyor belt 17. The crushed stones larger than the screen holes of the second screen 15 slide into the collection box 16 for collection. In this way, multi-stage crushing and multi-stage sorting of the crushed stones are realized, which can not only reduce the risk of excessive slack and damage of the conveyor belt, but also reduce the risk of crushed stones clogging inside the device, reduce the occurrence of device damage, and improve the sorting efficiency. The rotation of the front rotating shaft 41 drives the missing gear 9 to rotate. The rotation of the missing gear 9 pushes the tooth frame 8 to move downward, so that the connecting rod 11 pushes the first screen 5 to move downward, and the spring 10 is compressed accordingly. When the missing gear 9 rotates until it disengages from the teeth on the tooth frame 8, under the reset action of the spring 10, it can push the connecting rod 11 to drive the first screen 5 to move upward, so that the first screen 5 can vibrate up and down to avoid clogging of the first screen 5 and improve the screening efficiency.
[0022] The above describes the preferred embodiments of the present invention, which are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention.
