Crankshaft connecting rod type sunflower seed threshing and screening device

Abstract

The invention discloses a crankshaft connecting rod type sunflower seed threshing and screening device comprising a base, a threshing box, a conical threshing cylinder, a threshing head and a screening box; the base is provided with the threshing box; the conical threshing cylinder is horizontally arranged in the threshing box; a threshing cavity is arranged inside the conical threshing cylinder;the threshing head is arranged inside the threshing cavity; and at least two groups of supporting sliding rods are arranged and are slidably provided with the screening box. Sunflower seeds are threshed by mutual friction between threshing bulges on the threshing head and threshing bulges inside the threshing cavity; compared with a common threshing device, the crankshaft connecting rod type sunflower seed threshing and screening device has the advantages that the threshing stroke is longer due to the adoption of a V-shaped grinding cavity, so that the threshing is more effective, the threshing effect is improved, and the purity of the sunflower seeds is guaranteed; and a third connecting rod drives a second connecting rod to move left and right, so that the screening box is driven to moveleft and right, and furthermore, the screening speed of the sunflower seeds and the work efficiency are greatly increased.

Description

technical field [0001] The invention relates to a threshing device, in particular to a crankshaft connecting rod 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 ...
