Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a Polygonum multiflorum length screening machine. Background Art

[0002] The Polygonum multiflorum vine length screening machine is a device specially used for screening the length of Polygonum multiflorum vine. It can effectively grade and screen the Polygonum multiflorum vine for subsequent processing and use. Polygonum multiflorum vine, as a root-based Chinese medicine, will be cut into shorter pieces and sold. However, the length of the Polygonum multiflorum vine after cutting is inconsistent and needs to be screened. This equipment can be used for length screening of Polygonum multiflorum vine. This screening machine usually includes components such as a frame, a transport mechanism and a connecting plate, which can automatically screen the Polygonum multiflorum vine by length, thereby improving work efficiency and screening accuracy.

[0003] In the prior art, the cut Polygonum multiflorum is put into a hopper, and the Polygonum multiflorum drops from the hopper to a screening mechanism for screening, which has the following technical problems: first, when the Polygonum multiflorum vine passes through the screening mechanism during screening, impurities and dust will fall on the screening mechanism, and the machine needs to be cleaned frequently, increasing work intensity; second, when the cut Polygonum multiflorum vine falls from the hopper, the Polygonum multiflorum vine is easily blocked at the discharge port at the bottom of the hopper due to the large friction of its own material, and it needs to be manually unblocked, increasing work intensity and reducing work efficiency. Utility Model Content

[0013] The utility model is further configured as follows: a radial distance between the driving end and the driving shaft is greater than a radial distance between the buffer end and the driving shaft.

[0014] By adopting the above technical solution, the driving part intermittently drives the switch plate to swing through the driving end, so as to achieve the purpose of slowly vibrating the switch plate and preventing the material from being broken due to excessive vibration.

[0015] The utility model is further configured as follows: the filter plate is fixedly provided with a mounting shaft, the frame is provided with a slide groove, the end of the mounting shaft is connected with a slider, and the slider is embedded in the slide groove.

[0016] By adopting the above technical solution, the slider slides in the slide groove, the slider drives the installation shaft to slide on the frame, and the installation shaft drives the filter plate to move on the frame, so that the purpose of stable sliding of the filter plate can be achieved.

[0017] The utility model is further configured as follows: the reset member is configured as a spring.
