Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-5 The technical scheme is described in detail by the following embodiments of the present application.

[0026] The pre-screening device for astragalus seeds comprises a body 1 and a grinding box 2, the upper end of the body 1 is provided with a top cover 11, the inner wall of one end of the body 1 is fixedly connected with a limiting structure 12, the front surface of the body 1 is fixedly connected with a fixed box 13, the lower end of the grinding box 2 is fixedly connected with a grinding motor 21, the output end of the grinding motor 21 is installed with a grinding roller, the body 1 is arranged at the top end of the grinding box 2, the lower end inner wall of the body 1 is fixedly connected with a vertically arranged power motor 14, the top end of the power motor 14 is installed with an output shaft 15, the top of the output shaft 15 is installed with a rotator 3, the outer wall of the rotator 3 is provided with a plurality of screening holes 31, a plurality of discharge ports 32 are arranged on the bottom of the rotator 3 at equal angles along the circumferential direction, an electromagnetic valve 33 is installed at the discharge port 32, a first electric push rod 4 is installed on the side wall of the body 1, a vertically arranged mounting plate 41 is installed on the output end of the first electric push rod 4, the mounting plate 41 is located in the rotator 3, a plurality of scraping columns 42 are arranged on the mounting plate 41, and an auxiliary mechanism 5 for driving the rotator 3 to shake is arranged on the other side wall of the body 1.

[0027] The first electric push rod 4, the mounting plate 41 and the scraping column 42 are added on the basis of the original device, the scraping column 42 abuts against the inner wall of the rotator 3, the power motor 14 drives the rotator 3 to rotate, the scraping column 42 can clean the astragalus seeds blocked in the screening holes 31, the auxiliary mechanism 5 can drive the rotator 3 to shake, and thus the cleaning quality of the astragalus seeds blocked in the screening holes 31 can be further improved.

[0028] When the rotor 3 rotates, centrifugal force is generated, which can screen the astragalus seeds in the rotor 3. During screening, many astragalus seeds can easily form an astragalus seed pile. The contact area between the astragalus seed pile and the inner wall of the rotor 3 is small. Only the astragalus seeds in contact with the inner wall of the rotor 3 can be screened. The astragalus seeds that are not in contact with the inner wall of the rotor 3 need to wait until they hit the inner wall of the rotor 3 before they can be screened. In this process, the astragalus seeds will be concentrated in several places for screening, that is, some of the screening holes 31 of the rotor 3 are not utilized. The mounting plate 41 in this utility model can also serve to assist in breaking up the astragalus seed pile, avoid the astragalus seeds from piling up, and improve the utilization rate of the screening holes 31 of the rotor 3.

[0029] It is worth noting that the limiting structure 12 of the present invention is prior art and will not be described in detail here.

[0030] The auxiliary mechanism 5 includes a second electric push rod 51 and a knocking member 52. The second electric push rod 51 is horizontally arranged on the other side wall of the main body 1. The knocking member 52 is located between the inner wall of the main body 1 and the outer wall of the rotator 3. The knocking member 52 is fixedly connected to the output end of the second electric push rod 51. The second electric push rod 51 can drive the knocking member 52 to approach or move away from the outer wall of the rotator 3.

[0031] The striking member 52 includes a telescopic sleeve 521, a telescopic head 522 and a spring 523. The tail end of the telescopic head 522 is provided with a built-in groove 524. The head end of the telescopic head 522 is hemispherical. A plurality of abutment blocks 34 arranged at equal angles around the circumference of the rotator 3 are provided on the outer wall near the top thereof. The abutment blocks 34 are provided with a guide wedge surface 341 that abuts with the telescopic head 522. The telescopic sleeve 521 is horizontally connected to the output end of the second electric push rod 51. The telescopic head 522 is slidably arranged in the telescopic sleeve 521. The spring 523 is arranged in the telescopic sleeve 521 and the built-in groove 524. The power motor 14 drives the rotator 3 to rotate. Of course, the rotation speed should not be too fast. The telescopic head 522 can gradually abut against one of the abutting blocks 34. After the telescopic head 522 abuts against the guide wedge surface 341, the guide wedge surface 341 applies an extrusion force to the telescopic head 522, and the telescopic head 522 can be retracted into the telescopic sleeve 521. The spring 523 is compressed. Once the telescopic head 522 is separated from the abutting block 34, the spring 523 uses its own elastic force to drive the telescopic head 522 to quickly reset. The telescopic head 522 can hit the rotator 3, and the rotator 3 can vibrate.

[0032] Since the inner bottom wall of the rotor 3 is flat, when discharging qualified astragalus seeds, the astragalus seeds are easily retained on the inner bottom wall of the rotor 3. Therefore, a pushing mechanism 6 is also provided on the bottom end of the rotor 3 to push the retained astragalus seeds.

[0033] The pushing mechanism 6 comprises a connecting shaft 61, a top of the connecting shaft 61 is provided with a connecting seat 62, an outer wall of the connecting seat 62 is provided with a horizontal push rod 63, a bottom end center of the rotating device 3 is provided with a rotating hole matched with the connecting shaft 61 in rotation, the output shaft 15 is circular in cross section, the connecting shaft 61 is vertically and fixedly connected at the top of the power motor 14, the connecting seat 62 is located in the rotating device 3, and the push rod 63 is close to the inner bottom wall of the rotating device 3, when the power motor 14 drives the rotating device 3 to rotate, the connecting shaft 61 is in a stationary state, that is, the connecting seat 62 and the push rod 63 are also in a stationary state, the push rod 63 can assist in pushing the astragalus seeds on the inner bottom wall of the rotating device 3, and the astragalus seeds can be discharged once reaching the discharge port 32.

[0034] Preferably, the push rod 63 is provided with at least two, so as to improve the cleaning efficiency of the astragalus seeds remaining on the inner bottom wall of the rotating device 3.

[0035] The top of the rotating device 3 is provided with a baffle 35 integrally connected therewith and in a trumpet shape, so as to avoid the qualified astragalus seeds from splashing outside the rotating device 3.

[0036] Working principle: in use, the astragalus seeds are guided into the rotating device 3, and then the power motor 14 drives the rotating device 3 to rotate, the astragalus seeds can be screened through the screening holes 31, after screening is completed, all the electromagnetic valves 33 are opened, the power motor 14 still drives the rotating device 3 to rotate, the qualified astragalus seeds can be discharged from all the discharge ports 32, after all the qualified astragalus seeds are discharged, the first electric push rod 4 and the second electric push rod 51 work synchronously, the first electric push rod 4 drives the mounting plate 41 to move, so that the scraping brush column 42 abuts against the inner wall of the rotating device 3, the first electric push rod 4 stops working, the second electric push rod 51 drives the telescopic sleeve 521 to move towards the outer wall of the rotating device 3, the telescopic head 522 gradually abuts against the outer wall of the rotating device 3, after the telescopic head 522 is retracted into the telescopic sleeve 521 by a distance, the second electric push rod 51 stops working, and then the power motor 14 drives the rotating device 3 to rotate, the rotating speed should not be too fast, in this process, the scraping brush column 42 can scrape the screening holes 31, and the telescopic head 522 can reciprocatingly retract and extend, so that the rotating device 3 can continuously vibrate, so that the astragalus seeds blocked in the screening holes 31 can be cleaned.
