Vibration screening type sunflower seed threshing and screening device

Abstract

The invention discloses a vibration screening type sunflower seed threshing and screening device. The vibration screening type sunflower seed threshing and screening device comprises a base, a threshing box, a rotation motor, a threshing head and a screening box, wherein the threshing box is arranged on the base; the interior of the threshing box is provided with a threshing chamber; the lower endof the output shaft of the rotation motor is fixedly connected with the threshing head through a shaft coupling; and the screening box is fixedly connected with and arranged between two connecting rods located at the left and right sides of the screening box. According to the invention, sunflower seeds are threshed through threshing bulges arranged on the threshing head; compared with an ordinarythreshing device, the threshing chamber is arranged into a bending type, thereby achieving longer threshing stroke and more threshing effectiveness, improving threshing effects and guaranteeing the purity degree of sunflower seeds; and magnets and electromagnets are cooperated, thereby driving the screening box to realize upward-and-downward vibration, greatly accelerating the screening speed ofthe sunflower seeds and greatly improving working efficiency.

Description

technical field [0001] The invention relates to a threshing device, in particular to a vibration screening 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...

[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
