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.

[0021] See also Figure 1-4 In this embodiment, a vibrating screening machine with a multi-stage screening function includes a screening box 1, a feed hopper 2 and a discharge pipe 8 are fixedly installed on the top and bottom of the screening box 1, and a primary screening mechanism 6 and a secondary screening mechanism 7 are fixedly installed inside the screening box 1.

[0022] It should be noted that in the production process of Chinese medicinal materials, in order to ensure quality, most of them need to be screened so that larger and smaller Chinese medicinal materials can be selected to improve the quality of the medicinal materials. Therefore, the above-set screening box 1, feed hopper 2, discharge pipe 8, primary screening mechanism 6 and secondary screening mechanism 7 are coordinated to form a vibrating screening machine with multi-stage screening function.

[0023] An anti-blocking assembly 5 is installed inside the feed hopper 2. The anti-blocking assembly 5 includes a rotating shaft 501 rotatably installed on the front and rear inner walls of the feed hopper 2, and a stirring rod 502 is fixedly installed on the outer surface of the rotating shaft 501.

[0024] Specifically, when the Chinese medicinal materials are transported to the screening box 1 through the feed hopper 2 , the gravity of the Chinese medicinal materials will drive the stirring rod 502 and the rotating shaft 501 to rotate, so as to stir the Chinese medicinal materials and avoid clogging of the feed hopper 2 .

[0025] The primary screening mechanism 6 includes a filter plate 601 movably installed inside the screening box 1, a drive motor 602 is fixedly installed on the front inner wall of the screening box 1, a cam 603 is fixedly installed at the output shaft of the drive motor 602, a discharge port is opened on the left outer surface of the screening box 1, one end of the filter plate 601 extends to the outside of the discharge port, and the cam 603 is located at the bottom of the filter plate 601.

[0026] Specifically, when the driving motor 602 is turned on, the cam 603 is driven to rotate continuously, and the filter plate 601 is pushed up and down by the cam 603 to screen the Chinese medicinal materials. Larger ones can be discharged along the filter plate 601 and the discharge port, while some smaller Chinese medicinal materials will fall down.

[0027] The secondary screening mechanism 7 includes T-shaped rods 701 fixedly installed on the left and right inner walls of the screening box 1, auxiliary springs 702 are sleeved on the outer surfaces of the two T-shaped rods 701, sliders 703 are slidably installed on the outer surfaces of the two T-shaped rods 701, a screening frame 704 is fixedly installed between the tops of the two sliders 703, two return springs 705 are fixedly installed on the left outer surface of the screening frame 704, a rotating motor 706 is fixedly installed on the right outer surface of the screening box 1, a rotating rod 707 is fixedly installed on the output shaft of the rotating motor 706, a turntable 708 is fixedly installed on the end of the rotating rod 707 away from the rotating motor 706, a connecting rod 709 is installed inside the turntable 708, and a pull rod 710 is installed on the end of the connecting rod 709 away from the turntable 708.

[0028] Specifically, when some smaller Chinese medicinal materials fall into the screening frame 704, the rotating motor 706 drives the rotating rod 707 and the turntable 708 to rotate. The rotation of the turntable 708 pulls the screening frame 704 to swing left and right through the connecting rod 709 and the pull rod 710, assisted by the reset spring 705. At the same time, the screening frame 704 drives the slider 703 to slide on the T-bar 701, thereby realizing the screening of Chinese medicinal materials. After screening, the smaller Chinese medicinal materials will be discharged through the discharge pipe 8, while some larger Chinese medicinal herbs will remain in the screening frame 704.

[0029] A control panel 4 is fixedly mounted on the front of the screening box 1 , and a cabinet door 3 is hingedly mounted on the front of the screening box 1 .

[0030] Specifically, the control panel 4 is used to control the start and shut down of the device, and the cabinet door 3 is arranged so that the Chinese medicinal materials left in the screening frame 704 can be taken out.

[0031] When implementing, follow these steps:

[0032] 1) When in use, the device is connected to an external power source, and the Chinese medicinal materials are transported to the screening box 1 through the feed hopper 2;

[0033] 2) The gravity of the Chinese medicinal materials will then drive the stirring rod 502 and the rotating shaft 501 to rotate, stirring the Chinese medicinal materials;

[0034] 3) At the same time, the filter plate 601 is driven to shake up and down by starting the driving motor 602 to screen the Chinese medicinal materials. The larger ones can be discharged along the filter plate 601 and the discharge port, while some smaller Chinese medicinal materials will fall into the screening frame 704;

[0035] 4) Then the selection frame 704 is driven by the rotating motor 706 to swing left and right, and the selected Chinese medicinal materials with smaller volume are discharged through the discharge pipe 8, while some Chinese medicinal herbs with larger volume are retained in the selection frame 704;

[0036] 5) Finally, open the cabinet door 3 and take out the Chinese medicinal materials remaining in the screening frame 704.

[0037] In summary, the vibrating screening machine with multi-stage screening function is provided with a primary screening mechanism 6 and a secondary screening mechanism 7. When screening Chinese medicinal materials, the cam 603 is driven by the driving motor 602 to rotate continuously, and the cam 603 is used to push the filter plate 601 to shake up and down continuously, so as to screen the Chinese medicinal materials. Larger ones can be discharged along the filter plate 601 and the discharge port, while some smaller Chinese medicinal materials will fall into the screening frame 704. By driving the screening frame 704 to shake left and right under the drive of the rotating motor 706, multi-stage screening of Chinese medicinal materials can be achieved, and Chinese medicinal materials of different sizes can be quickly and effectively separated.
