Description

Header Feeding Device for Misaligned Corn Harvester

technical field

The invention provides a header feeding device for a non-aligned corn harvester, which belongs to the technical field of agricultural harvesting.

Background technique

At present, the corn cultivation system and planting agronomy in various regions of our country are quite different, and the planting row spacing is also various. The planting of corn seriously restricts the development of corn harvester.

At present, there are generally two types of misaligned corn harvester headers in China: one is the chainless corn misaligned harvester, the straw is introduced through the grain divider, and the vertical shaft type knife is cut off, and the cut straw is pulled by the reel. When it is sent to the ear picking operation, the reliability is poor due to easy blockage during work, and the loss rate of fruit ear is high; a kind of harvesting device with non-alignment such as patent number CN201418281Y, the reel chain and reel teeth protrude from the edge of the header guide shield In addition, the contact between the reel chain and the reel teeth and the corn stalks has been increased, and the corn stalks that have been in contact with the corn stalks and half-lodged corn stalks have been included in the harvesting range to achieve corn misalignment. When the inclination angle of the corn stalks is large, it is easy to be harvested. overthrow.

Contents of the invention

In order to break through the bottleneck in the development of corn harvesters, the invention provides a header feeding device for corn harvesters with reasonable design and good adaptability.

The present invention is a feeding device for corn harvesting platform capable of realizing non-aligned harvesting, which includes a frame, large and small grain dividers, fixed knives, moving knives, reel drums, reel chains, The grass guard and the gearbox are characterized in that the gearbox is fixed on the frame, the fixed knife is fixed on the gearbox, the movable knife is connected to the output shaft above the gearbox, and is above the fixed knife and maintains a certain gap with the fixed knife. The reeling drum is located above the moving knife and is connected with the driven sprocket shaft of the reeling chain. The driven sprocket shaft is fixed on the frame through the bearing seat, the reeling chain is located above the frame, and the grass guard is fixed on the machine On the frame, the working surface is in line with the forward direction of the machine, and the large and small grain dividers are fixed on the frame, located directly in front of the reeling drum.

As for the feeding device of the misaligned corn harvester, the large grain divider and the small grain divider are fixed on the frame, located directly in front of the reeling drum, and cooperate with the reeling drum to realize the division and clamping of straw.

In the header feeding device of the misaligned corn harvester, the number of teeth on the reel drum increases sequentially from top to bottom, and there are one or more dials.

In the feeding device for the cutting table of the non-aligned corn harvester, the moving knife can adopt various forms such as straight knife, curved knife or disc knife, and the number of straight knife or curved knife is 2 or more, and the corn stalk is fed Cutting with support is used in the process.

In the cutting table feeding device of the misaligned corn harvester, the reeling drum and the moving knife are coaxially installed, and the rotating speed of the moving knife is higher than that of the reeling drum.

In the feeding device for the header of the non-aligned corn harvester, the working plane of the grass shield guides the corn stalks into the ear picking unit of the header of the corn harvester.

Compared with the prior art, the present invention has the following advantages: when the straw is fed to the machine through the large and small grain dividers, the disc knife is used to cut off, which reduces the power consumption in the straw feeding process, and at the same time, the disc knife has a good impact on the straw There is also a certain dialing effect, which can better achieve misaligned harvesting; in addition to the reel chain, a reel is also added to achieve better feeding of corn stalks; the speed of the moving knife and the reel is different. The same, it can be adjusted according to the working conditions; the grass baffle is fixed on the frame, located in the middle and rear of the reel drum, and the working plane of the grass baffle covers the working area of the reel chain at the same time, which can better guide the corn stalks into the corn The ear picking unit of the harvester header picks the ears and prevents congestion caused by the shoveling of the reel.
