Ear and stalk harvesting corn harvester provided with double-layer combined cutting table

Abstract

The invention relates to an ear and stalk harvesting corn harvester provided with a double-layer combined cutting table. The ear and stalk harvesting corn harvester comprises the double-layer cuttingtable; an ear picking and cutting table positioned at the upper part comprises a plurality of groups of ear picking operation units arranged side by side, each group of ear picking operation units comprises a strong feeding mechanism, a stalk clamping mechanism and an ear output mechanism which are sequentially connected from front to back, a tool-setting ear picking mechanism is arranged under the ear output mechanism, and an ear conveying auger, an ear elevator, an ear peeler and a grain box are sequentially connected behind the plurality of groups of ear picking operation units; a stalk cutting and recovery table positioned at the lower part comprises a reciprocating cutter, a conveying chain rake structure, a conveying auger, a stalk feeding mechanism, a stalk pulverizing mechanism, anacceleration mechanism and a throwing output mechanism which are sequentially connected from front to back; and the stalk cutting and recovery table further comprises a stalk pulverizer for pulverizing remaining stalk roots as well as ear bracts and leaves on the ground. The harvester is smooth in operation, free from blockage and high in harvesting speed.

Description

technical field [0001] The invention belongs to the technical field of corn harvesters, and relates to the technology of both ear and stem harvesting, in particular to a corn harvester equipped with double-layer combined headers. Background technique [0002] At present, the mainstream corn harvesting machinery in the market is mainly dedicated machinery, namely ear harvesting machinery, grain harvesting machinery, green fodder harvesting machinery, etc. For corn harvesting operations, there are very few models that harvest ears and stalks at the same time. Most of the current harvesters that harvest both ears and stems have the shortcomings of low harvesting efficiency and poor harvesting quality. The specific performance is that the harvesting speed is mostly between 3 and 4 km / h, the number of acres harvested per hour is mostly 5-6 acres. After the operation, the stalks on the ground are too high, the length of the stalks is not uniform, the cutting is continuous, and the...

Problems solved by technology

For corn harvesting operations, there are very few models that harvest ears and stalks at the same time. Most of the current harvesters that harvest both ears and stems have the shortcomings of low harvesting efficiency and poor harvesting quality. The specific performance is that the harvesting speed is mostly between 3 and 4 kilometers per hour, the number of acres harvested per hour is mostly 5-6 acres, and there are phenomena such as excessively high stalks on the ground after operation, uneven lengths of stalks, continuous cutting, and throwing out straws with soil, etc.

The existing ear and stem harvesting models equipped with double-layer headers basically have unreasonable harvesting processes on the upper and lower headers, resulting in a series of problems such as blockage of headers and uneven feeding of stalks.
