Gear matched type threshing and screening device for sunflower seeds

Abstract

The invention discloses a gear matched type threshing and screening device for sunflower seeds. The gear matched type threshing and screening device comprises a base, a threshing tank, a conical threshing barrel, a threshing head and a screening tank. The threshing tank is arranged on the base, the conical threshing barrel is horizontally arranged inside the threshing tank, a threshing cavity is arranged inside the conical threshing barrel, the threshing head is arranged inside the threshing cavity, and the screening tank is slidably mounted on at least two groups of support slide bars. The gear matched type threshing and screening device has the advantages that rubbing effects can be realized by threshing protrusions on the threshing head and threshing protrusions inside the threshing cavity, and accordingly threshing can be carried out for the sunflower seeds; the gear matched type threshing and screening device with V-shaped grinding cavities is long in threshing stroke as comparedwith common threshing devices, accordingly, effective threshing can be carried out, threshing effects can be improved, and the purity of the sunflower seeds can be guaranteed; a second connecting rodcan be driven by a third connecting rod to move in the left-right directions, accordingly, the screening tank can be driven to move in the left-right directions, the sunflower seed sieving speeds canbe greatly increased, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a threshing device, in particular to a gear-cooperated 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, time-co...

[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
