Knocking type low-impurity-rate sunflower seed combine harvester

Abstract

The invention provides a knocking type low-impurity-rate sunflower seed combine harvester. The knocking type low-impurity-rate sunflower seed combine harvester comprises a picking and conveying device, a first conveying system, a knocking threshing device, a second conveying system, a flower disc collecting and discharging device, a sunflower seed stock bin, a walking system and a main rack; the picking and conveying device is installed on the main rack; the knocking threshing device is located above the second conveying system and comprises a lifting rod, a cam mechanism, a transverse rod, a supporting rod, a fixed hinge and a knocking plate; a balance pivot is arranged in the middle of the transverse rod, one end of the transverse rod is hinged to the lifting rod, the supporting rod is mounted at the other end of the transverse rod, and the knocking plate is mounted on the supporting rod through the fixed hinge; and a stock bin comprises the flower disc collecting and discharging device and the sunflower seed stock bin which are separated from each other, the flower disc collecting and discharging device is located behind the second conveying system, and the sunflower seed stock bin is located below the second conveying system. According to the sunflower harvester, the labor intensity of workers is reduced, certain stability and reliability are achieved, the fault rate is low, low-impurity-rate harvesting of sunflowers is achieved, and the grain condition is improved.

Description

technical field [0001] The invention relates to the field of sunflower tray harvesting equipment, in particular to a percussion-type combined harvester for sunflower seeds with low impurity content. Background technique [0002] Sunflower is a high-quality economic crop and one of the main oil crops in my country. It has broad market potential and is widely used in food processing industry, chemical industry, agriculture and animal husbandry and other fields. After years of development, my country's sunflower planting area has leapt to the first place in the world. However, for the harvesting of sunflowers, most areas are still mainly harvested manually, with high labor intensity and low production efficiency. The sunflower harvesters used in a small number of areas have problems of large seed loss, high impurity content, and serious wear of the drum. The mechanized harvesting of sunflower is limited. [0003] At present, for the harvesting and threshing of sunflowers, the...

Problems solved by technology

[0004] The above technologies all propose methods and equipment designs for the harvesting and threshing of sunflowers. At present, most harvesters use the above-mentioned threshing drums or crushing rollers for threshing. However, due to the particularity of the growth of sunflower seeds, destroying the flower disc will cause high impurity content and damage the seeds at the same time. The appearance of the grain is not conducive to the cleaning of the grains, which will damage the interests of the majority of farmers
