Sunflower harvesting header

Abstract

The invention relates to sunflower harvesting header. The sunflower harvesting header comprises stalk distributing grooves, stalk shifting devices, stalk cutting devices and a conveying device and is characterized in that the front end of each stalk distributing groove is V-shaped, the stalk distributing grooves are parallelly arranged in an equal-interval manner, a gap between every two adjacent stalk distributing grooves is a stalk feeding channel, the stalk shifting devices are arranged on two sides of each stalk feeding channel, one stalk cutting device is arranged at the tail end of each stalk feeding channel, the stalk shifting devices are used for shifting sunflower stalks towards the stalk cutting devices, the stalk cutting devices are used for cutting the sunflower stacks shifted by the stalk shifting devices, and the conveying device is used for conveying cut-off sunflower heads to a next-level processing device. The sunflower harvesting header has the advantages that mechanical harvesting of the sunflower heads is achieved, and high operation efficiency is achieved; inclined sunflower plants can be lifted to prevent the sunflower plants from being crushed, a stalk lifting effect is achieved, and rotary blades and stalk shifting chain sprockets rotate at the same time and the rotary blades and stalk shifting chains move in a coordinated manner to efficiently cut the sunflower plants.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a sunflower harvesting header. Background technique [0002] At present, a large number of sunflowers are planted in China, but there is no ready-made sunflower combine harvester. Some of the existing harvesting machines are directly refitted from rice and wheat combine harvesters, which have poor adaptability, high loss rate, high power consumption, and easy winding. Problem; there is still a small part of machines that can only simply harvest flower discs, and then perform manual or machine threshing. This harvesting method has many operating procedures, a large amount of labor, and low efficiency. At present, the existing sunflower mechanical operation equipment has basically solved the problem of sunflower threshing. threshing and cleaning separation, but there is no corresponding header, mainly manual picking of sunflower trays and then put into the threshing and separa...

[0002] At present, a large number of sunflowers are planted in China, but there is no ready-made sunflower combine harvester. Some of the existing harvesting machines are directly refitted from rice and wheat combine harvesters, which have poor adaptability, high loss rate, high power consumption, and easy winding. Problem; there is still a small part of machines that can only simply harvest the flower discs, and then perform manual or machine threshing. This harvesting method has many operating procedures, a large amount of labor, and low efficiency. At present, the existing sunflower mechanical operation equipment has basically solved the problem of sunflower threshing. threshing and cleaning separation, but there is no corresponding header, mainly manual picking of sunflower trays and then put into the threshing and separation device for threshing and cleaning, labor intensity is high, production cost is high, and harvesting efficiency is low
