Description

Technical Field

[0001] The utility model relates to the field of screening of Erigeron breviscapus seeds, in particular to a seed screening device for Erigeron breviscapus planting. Background Art

[0002] Erigeron breviscapus, a Chinese medicinal herb, is the dried whole herb of the Asteraceae family plant, Erigeron breviscapus. It is harvested in summer and autumn, freed of impurities, and sun-dried. It has a pungent, slightly bitter flavor and a warm nature, entering the Heart and Liver meridians. It promotes blood circulation, relieves pain, and dispels wind and cold. It is commonly used for stroke-induced hemiplegia, chest pain, heart pain, rheumatic pain, headaches, and toothaches.

[0003] Before planting, the seeds of Erigeron breviscapus need to be screened. In the existing method of screening the seeds of Erigeron breviscapus, most of the seeds are placed on a screening plate, and the screening plate is manually shaken by staff to achieve a quick screening effect. Shaking the screening plate for a long time is labor-intensive, time-consuming and labor-intensive, increases the unnecessary workload of the staff, and is inconvenient for the staff to use. For this reason, we propose a seed screening device for Erigeron breviscapus planting. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a seed screening device for planting Erigeron breviscapus, which has the following beneficial effects:

[0016] When the seeds need to be screened during planting of Asarum breviscapus, the seeds to be screened are first poured into the interior of the first screening shell, and the seeds can be preliminarily screened by opening a first screening hole inside the first screening shell. After the initial screening is completed, the seeds will fall into the interior of the second screening shell due to gravity, and the seeds after the initial screening can be screened for the second time by opening a second screening hole inside the second screening shell. By starting the motor, the output end of the motor drives the first rotating shaft and the turntable to rotate, and then drives the second rotating shaft to move in a circular arc, and then drives the connecting plate to rotate while moving on the second rotating shaft and the third rotating shaft. At this time, the first screening shell and the second screening shell can be driven to move, and the first screening shell and the second screening shell are connected. The slider is slidably connected to the inside of the slide, so that the first screening shell and the second screening shell are more stable when moving. By rotating the turntable, the first screening shell and the second screening shell can be moved back and forth, and the seeds can be accelerated to pass through the first screening shell and the second screening shell to achieve rapid screening. The above structure is convenient for the staff to screen the seeds when planting the Glechoma longituba, and the screening effect can be improved through the secondary screening. By moving the first screening shell and the second screening shell back and forth, the seeds can be accelerated to pass through the first screening shell and the second screening shell to achieve rapid screening, which reduces the screening time, reduces the unnecessary workload of the staff, and greatly facilitates the use of the staff.
