Straw set corn harvester

Abstract

The invention discloses a straw strip collection type corn cutting table and aims at providing a straw strip collection type corn cutting table which is high in straw utilization rate and low in straw cleaning, recovery and recycling cost and facilitates soil protection. The straw strip collection type corn cutting table comprises a machine frame, a divider, a cluster picking device, a cluster conveyer, a transmission system and a straw conveyer arranged under the rear portion of the cluster picking device in the transverse direction, wherein the divider, the cluster picking device, the cluster conveyer and the transmission system are installed on the machine frame, and cutting throwing devices are arranged under the front portion of the straw conveyer and parallel to the rotation axis of the straw conveyer. The machine frame is provided with a side bottom beam and a middle bottom beam, the cutting throwing devices are bilaterally, symmetrically and rotatably supported and installed on the side bottom beam and the middle bottom beam respectively, and cutter groups are installed on shaft rollers of the cutting throwing devices in the axial direction in series. The straw strip collection type corn cutting table is suitable for corn cluster picking and straw collection and laying operation.

Description

technical field [0001] The invention relates to a corn harvesting platform, in particular to a stalk-collecting corn harvesting platform. Background technique [0002] my country's corn planting area is 520 million mu, and the corn stalk output is about 273 million tons. Corn stalk is an important biomass resource, which can be used for yellow silage, fuel power generation, etc., and has great utilization potential. At present, the mechanized harvesting rate of corn in my country has reached 60%, and most of them adopt the harvesting process of ear picking, straw crushing and returning to the field. The corn harvesting platform used in this harvesting process is only used for ear picking, and the straw after ear picking is crushed and scattered in the field by a special straw returning machine. As a result, a large amount of scattered straw fell into the furrows after machine harvesting and could not be effectively collected and utilized. As a result, a large amount of str...

AI Technical Summary

Problems solved by technology

Existing problems: First, the straw picking rate of existing livestock hay rakes is extremely low due to the influence of ridge farming factors, and most of the ridge straws are left behind in the field. This method is prone to recycling of straw with soil, such as combustion power generation, which is not conducive to the exertion of thermal efficiency The second is that the collection and utilization of straw can only be completed by using multiple models in sections, which increases the cost of straw recycling; the third is that the continuous compaction of multiple machines into the ground causes soil compaction, which is not conducive to soil protection and sustainable utilization
