[0030] The first screen 10 is located above the second screen 4, the first screen 10 is elastically connected to the sorting box 1, and the second screen 4 is connected to the sorting box 1. The scraper 7 is arranged on the upper end surface of the second screen 4. At this time, the output end of the second drive motor 20 is connected to the scraper 7, driving the scraper 7 to rotate on the second screen 4, so as to disturb the material accumulated on the second screen 4 and avoid clogging of the second screen 4.

[0031] Further explanation, in order to improve the vibration reliability and stability of the first screen 10, a cam 9 is provided in the sorting box 1. The cam 9 is rotatably connected to the sorting box 1 through a rotating rod 8. The output end of the first drive motor 16 is also transmission-connected to the rotating rod 8 to drive the cam 9 to rotate.

[0032] One end of the first screen 10 is hinged to the sorting box 1 , the other end of the first screen 10 contacts the cam 9 , and the other end of the first screen 10 is also connected to a spring 12 , which is connected to the sorting box 1 through a connecting seat 11 .

[0033] Preferably, there are two first screens 10, which are symmetrically arranged up and down, respectively called an upper screen and a lower screen, and both the upper screen and the lower screen are arranged horizontally and inclined, and the cam 9 is located between the upper screen and the lower screen.

[0034] At this time, the spring 12 on the upper screen is located above the upper screen, and the spring 12 on the lower screen is located below the lower screen. There are two first discharge ports 22, and the two first discharge ports 22 are respectively set corresponding to the upper screen and the lower screen.

[0035] Preferably, when the pore sizes of the upper screen and the lower screen are the same, it is used to screen the gangue material after being filtered by the upper screen, avoiding some materials being extruded from the upper screen due to impact and improving the screening quality; when the pore size of the upper screen is larger than that of the lower screen, it increases one level of screening, improves the separation level of the gangue, and meets different screening requirements.

[0036] Further explanation, the output end of the first driving motor 16 is connected with a worm 17, the worm 17 is vertically arranged, and a driving box 15 is sleeved outside the worm 17 for improving the safety of the equipment.

[0037] The worm 17 is in transmission connection with the rotating crushing roller 14 through a first worm gear 18, and the worm 17 is connected with the rotating rod 8 through a second worm gear 19, reducing the number of drives and the volume of the overall structure to meet the transportation requirements.

[0038] Further explanation, the second driving motor 20 is arranged outside the sorting box 1, the output end of the second driving motor 20 is connected with a rotating shaft 2, the second screen 4 is sleeved outside the rotating shaft 2 through a sleeve 3, and the scraper 7 is connected with the rotating shaft 2.

[0039] At this time, a support frame 24 is arranged outside the bottom of the sorting box 1 to increase the height between the sorting box 1 and the ground, and a third discharge port 23 is opened at the bottom of the sorting box 1, and the third discharge port 23 is located below the second screen 4.

[0040] A first discharge port 22 and a second discharge port are arranged on the side wall of the sorting box 1, the first discharge port 22 is opposite to the first screen 10, and the second discharge port is opposite to the second screen 4, which is convenient for discharging and collecting.

[0041] Further explanation, in order to improve the structural strength of the scraper 7, a vertical rod 6 is selected to be arranged on the scraper 7, a connecting rod 5 is arranged at the top of the vertical rod 6, the number of the vertical rods 6 is multiple, and the multiple vertical rods 6 are arranged at intervals along the length direction of the scraper 7. The rotating shaft 2 passes through the scraper 7 and is connected with the connecting rod 5, and the connecting rod 5 is sleeved outside the rotating shaft 2 and is connected with the rotating shaft 2.

[0042] In order to improve the collection efficiency of the material passing through the second screen 4, a diversion plate is selected to be arranged at the bottom of the second screen 4. The diversion plate is of a fan-shaped structure. At this time, the rotating shaft 2 passes through the diversion plate, and at this time, the third discharge ports 23 are located on the opposite sides of the rotating shaft 2, and the two third discharge ports 23 correspond to the two sides of the diversion plate.

[0043] Working principle:

[0044] During use, the second drive motor 20 is turned on, causing the second drive motor 20 to drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the connecting rod 5 and the vertical rod 6 will be driven to rotate synchronously. As a result, the scraper 7 at the bottom of the vertical rod 6 rotates on the top of the second screen 4, enabling the second screen 4 to effectively disturb the gangue that does not meet the specifications and output it from the second discharge port. At the same time, by rotating and scraping, it avoids the fine aggregate from getting stuck in the screen mesh and causing blockage, preventing normal feeding, and improving the practicality of the device.

[0045] The first drive motor 16 is turned on, causing the first drive motor 16 to drive the second worm gear 19 to rotate through the worm 17. The second worm gear 19 then drives the cam 9 to rotate through the rotating rod 8. During the rotation of the cam 9, it continuously pushes the upper and lower first screens 10 to shake up and down. Whenever the first screen 10 is pushed in the opposite direction, the spring 12 will push / pull the first screen 10 back. This process is repeated, causing vibration on the surface of the first screen 10, avoiding material blockage, and improving the sorting efficiency of the device.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
