Rotary-threshing-type sunflower seed threshing and screening device

Abstract

The invention discloses a rotary-threshing-type sunflower seed threshing and screening device. The device comprises a base, a threshing box, a rotating motor, a thresher and a screening box, wherein the threshing box is arranged on the base, a threshing chamber is formed inside the threshing box, the thresher is fixedly connected to the lower end of an output shaft of the rotating motor through acoupling, at least two sets of supporting sliding bars are arranged, and the screening box is mounted on the supporting sliding bars in a slidable manner. Sunflower seeds are threshed through threshing bulges on the thresher, and a threshing stroke is longer due to the bent threshing chamber compared with the ordinary threshing device, so that the threshing is more efficient, the threshing effectis improved, and the purity of the sunflower seeds is guaranteed; and a special-shaped gear is driven to be matched with a gear rack through a driving motor, so that the screening box is driven to move left and right, the screening speed of the sunflower seeds is greatly accelerated, and the working efficiency is greatly increased.

Description

technical field [0001] The invention relates to a threshing device, in particular to a rotary threshing type sunflower seed threshing and screening device. Background technique [0002] In recent years, due to the continuous rise in the price of edible sunflowers, the planting area of ​​edible sunflowers has shown a trend of rapid expansion. [0003] Although agricultural machinery companies have developed some combine harvesters, the damage of the combine harvesters to sunflower seeds is relatively large, and the combined [0004] The cost of the harvester is high, the temperature in the northern countryside is low, and the farmers have a long slack period. If the sunflowers can be dried on the plate and then harvested, it will not only avoid a lot of wet sunflowers harvested and go home. treatment to ensure the quality of sunflowers, but the traditional methods of beating threshing with artificial sticks and cleaning with manual dustpans are inefficient, poor in effect, t...

[0003] Although agricultural machinery companies have developed some combine harvesters, the damage of the combine harvesters to sunflower seeds is relatively large, and the combined

[0004] The cost of the harvester is high, the temperature in the northern rural areas is low, and farmers have a long slack time. If the sunflowers can be dried on the plate before harvesting, it will not only avoid a lot of wet sunflowers being harvested and go home, moldy and deteriorate the quality. treatment to ensure the quality of sunflowers, but the traditional method of beating threshing with artificial sticks and cleaning with manual dustpan is inefficient, poor in effect, time-consuming and labor-intensive, and the effect of threshing is not good at the same time, and it needs to be screened after threshing. low
