Harvesting device suitable for spike-stalk distributary harvesting of highland barley

Abstract

The invention relates to the field of agricultural machinery, in particular to a harvesting device suitable for spike-stalk distributary harvesting of highland barley. The harvesting device comprises a frame and a bracket, wherein a reel and a cutter are arranged on the bracket; chain clamping transport mechanisms are arranged between the bracket and the frame and used for conveying stalks, cut off by the cutter and arranged in rows under the action of the reel, toward the frame; a multi-layered free-swinging cutter mechanism for separating the stalks from spikes and crushing the stalks is arranged at the position, below the tail ends of the chain clamping transport mechanisms, on the frame; a stalk conveying mechanism is arranged below the multi-layered free-swinging cutter mechanism; a grass collecting and bundling mechanism is arranged at the tail end of the stalk conveying mechanism; and a spike conveying mechanism is arranged in the position, at the tail ends of the chain clamping transport mechanism, on the frame, and a highland barley spike threshing mechanism is arranged at the tail end of the spike conveying mechanism. The harvesting device is simple in structure and low in cost, can realize harvesting of both grain and grass, and adapts to the characteristics of highland barley spikes, and the threshing efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a harvesting device suitable for split harvesting of highland barley ears and stems. Background technique [0002] Highland barley is an important food crop, mainly distributed in my country's Tibet, Qinghai, Ganzi and Aba in Sichuan and other regions. Highland barley is widely used, its grain is the main grain of local residents, and barley stalk is the main feed for local people. Since the awn and grass cannot be separated when the rice-wheat combine harvester is used, it cannot meet the needs of farmers for double harvest of grain and grass. Ear heads are threshed. [0003] On the other hand, this kind of highland barley head has an ultra-low grass-to-grain ratio. The rice-wheat threshing equipment in the prior art is cumbersome, inefficient, wasteful of energy, and expensive. It can only be a decoration. [0004] In summary, due to the lack of relevant ...

Since the awn and grass cannot be separated when the rice-wheat combine harvester is used, it cannot meet the needs of farmers for double harvest of grain and grass. Threshing

[0003] On the other hand, this kind of highland barley head has an ultra-low grass-to-grain ratio. The rice-wheat threshing equipment in the prior art is cumbersome, inefficient, wasteful of energy, and expensive. can only be a decoration

[0004] In summary, due to the lack of relevant agricultural machinery and equipment, the cultivation and production of highland barley in my country has been severely restricted.
