Description

Technical Field

[0001] The utility model relates to the technical field of screening agricultural tools, in particular to a Fritillaria thunbergii screening device. Background Art

[0002] Fritillaria thunbergii is a perennial herb of the genus Fritillaria in the family Liliaceae. It is a relatively precious traditional medicinal material in my country and an important commodity for export and foreign exchange earning. It is very popular in the domestic and foreign Chinese medicinal material markets. Fritillaria thunbergii is divided into two parts: the underground bulb (the medicinal part) and the aboveground stem, and the underground bulb part is harvested.

[0003] Harvesting Fritillaria foetida is a time-consuming and laborious task. Harvesting is extremely time-sensitive, so it needs to be collected in a timely manner. If the Fritillaria foetida is not harvested in time, it will rot in the field. Therefore, farmers hire a large number of workers when harvesting Fritillaria foetida. The large number of workers, high labor intensity, and high operating costs restrict the development of the Fritillaria foetida industry. With the continuous increase in labor costs and the difficulty in hiring workers, the harvesting of Fritillaria foetida has become a bottleneck problem for farmers to increase their income and expand the scale of planting. Therefore, realizing mechanized harvesting has become a top priority for the production of Fritillaria foetida.

[0004] Mechanical screening is a key link in the mechanized harvesting of Fritillaria cirrhosa. A drum screen is usually used for screening Fritillaria cirrhosa. However, the damage to the Fritillaria cirrhosa bulbs during the screening process is mainly caused by collisions. The Fritillaria cirrhosa bulbs collide and rub against the screen and the drum wall in the drum. This physical action causes damage to the internal tissues, among which the breakage and local damage caused by collisions are particularly serious. As seeds, the damaged Fritillaria cirrhosa bulbs are affected by harmful bacteria in the soil, resulting in a decrease in seed regeneration ability, affecting the development and growth of seedlings, and easily leading to a decrease in yield. As a commodity, the cells at the damaged position of Fritillaria cirrhosa change, resulting in changes in the effective ingredients. In addition, they cannot be dried in time, resulting in poor appearance, poor quality and price drop, causing economic losses. To this end, we provide a Fritillaria cirrhosa screening device to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the Fritillaria thunbergii screening device has the following beneficial effects:

[0013] The utility model sets the coordination between the screen, the inclined angle lifting plate and the non-inclined angle lifting plate.

Then, the inclined angle lifting plate, driven by the screen, can guide the flow of the sieved material of the flat fritillaria during the screening process.

At this time, the screen can continuously screen the soil during the flow of the flat fringe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present embodiment provides a Fritillaria thunbergii screening device, which is used to reduce the breakage rate of Fritillaria thunbergii during the screening process of Fritillaria thunbergii. By setting the coordination between the screen, the inclined angle lifting plate and the non-inclined angle lifting plate, when the Fritillaria thunbergii screened material enters the interior of the screen through the lifting device body, the rotation of the screen drives the inclined angle lifting plate and the non-inclined angle lifting plate to rotate. Then, the inclined angle lifting plate, driven by the screen, can guide the flow of the Fritillaria thunbergii screened material during the screening process. While the inclined angle lifting plate and the non-inclined angle lifting plate guide the movement of the Fritillaria thunbergii, the apertures on their surfaces also screen them, thereby improving the screening efficiency. The aperture can reduce the flow velocity of the Fritillaria thunbergii, thereby reducing the collision force when the Fritillaria thunbergii is screened, thereby reducing the breakage rate of the Fritillaria thunbergii.

[0023] The inner wall of the screen 4 is fixedly connected with three groups of inclined angle lifting plates 14. In the present embodiment, the angle of the inclined angle lifting plates 14 drives the material to be lifted and guides it at the same time, so that it gradually moves toward the direction of the flow plate 7 during the screening process. The outer surface of the inclined angle lifting plates 14 is provided with a plurality of perforations. The inner wall of the screen 4 is fixedly connected with ten circular arrays of non-inclined angle lifting plates 15. The outer surface of the non-inclined angle lifting plates 15 is provided with a plurality of perforations. In the present embodiment, the size of the perforations provided on the surfaces of the inclined angle lifting plates 14 and the non-inclined angle lifting plates 15 is 8×8mm².

[0025] The inner wall of the flow trough 6 is fixedly connected with a flow plate 7. In this embodiment, the flow trough 6 can support the inner wall of the screen 4, thereby ensuring the stability of the screen 4 during rotation. The outer surface of the flow plate 7 is fixedly connected with a support plate 8, and the outer surface of the support plate 8 is fixedly connected to the outer surface of the side plate 5.

Then the rotating shaft 10 drives the support rod 12 to rotate, thereby driving the horizontal support bar 13 and the flow trough 6 to rotate, so that the screen 4 rotates. Finally, the rotation of the screen 4 drives the inclined angle lifting plate 14 and the non-inclined angle lifting plate 14 to rotate. The material plate 15 rotates, and then the inclined angle lifting plate 14, driven by the screen 4, can guide the flow of the flat Fritillaria sieve material during the screening process. While the inclined angle lifting plate 14 and the non-inclined angle lifting plate 15 guide the movement of the flat Fritillaria, the apertures on their surfaces can increase their screening efficiency, and the apertures increase the friction of the flat Fritillaria, thereby reducing the flow speed of the flat Fritillaria, reducing the collision force when the flat Fritillaria is flowing and screening, thereby reducing the breakage rate of the flat Fritillaria, and then when the flat Fritillaria sieve material moves to the non-inclined angle lifting plate 15, it is lifted to the flow plate 7 for material collection.
