A kind of comb type sunflower harvesting method and header

Abstract

The invention relates to a comb-cutting type sunflower harvesting method and header. The Comb-cutting type sunflower harvesting method and header header comprises a rack, a comb-supporting type standing grain pulling mechanism, a translation mechanism, a lifting mechanism, a cutting mechanism and a conveying mechanism. The cutting mechanism is used for cutting off stalks of sunflowers. The comb-supporting type standing grain pulling mechanism is used for supporting sunflower discs of the sunflowers in good time and throwing plants to the conveying mechanism after the lower ends of the plants are cut off. The translation mechanism and the lifting mechanism are used for driving the comb-supporting type standing grain pulling mechanism to move in the horizontal direction and the vertical direction respectively. The functions of a divider are integrated by the comb-supporting type standing grain pulling mechanism, hitting of a standing grain wheel to the sunflower discs and damage caused by grain falling are greatly reduced, the position of the comb-supporting type standing grain pulling mechanism can be independently adjusted up and down or front and back, comb-supporting and cuttingactions are timely, effectively and stably completed in cooperation with the cutting mechanism, and therefore the header adapts to the differentiation of sunflower plant heights and sunflower disc distribution height ranges under the condition of different plots or varieties.

Description

technical field [0001] The invention belongs to the field of agricultural harvester machinery, and in particular relates to a combing type sunflower harvesting method and a header. Background technique [0002] Sunflowers are divided into edible sunflowers and oil sunflowers, referred to as edible sunflowers and oil sunflowers. Sunflowers are characterized by large and single sunflower plates, straight middle and lower parts of the plant, and few branches. At present, most of the domestic sunflower harvests are still harvested manually, with a low degree of mechanization. Most of the existing sunflower headers are borrowed from foreign headers or modified from rice and wheat headers. The research on the characteristics of sunflowers is insufficient, and there are many problems. Such as CN204031845U patent has announced a kind of sunflower harvesting head, has realized the mechanized harvest of eating sunflower dish, need not take dish manually; The sunflower tray has straw...

AI Technical Summary

Problems solved by technology

Such as CN204031845U patent has announced a kind of sunflower harvesting head, has realized the mechanized harvest of eating sunflower dish, need not take dish manually; The sunflower tray has straws of different lengths, which are not suitable for sunflowers with thicker plants or uneven heights.

The above headers solve a small part of the problems in the mechanized harvesting of sunflowers, but there are still common problems in sunflower headers in our country that the damage of the reel to the sunflower plate is large, and the loss rate of the headers is high, and the reeling of the domestic sunflower headers The wheel is driven by a pair of hydraulic cylinders, and cannot move up and down flexibly and independently, which makes it inconvenient to flexibly adjust the position of the reel according to the growth of sunflower crops during field experiments
