Description

A corn harvesting device

technical field

The utility model belongs to a corn harvesting device, in particular to a small corn harvesting device installed on a hand-held or small tractor.

Background technique

Most of the currently widely used corn harvesters are relatively large, with high efficiency and fast speed. However, its body is large, its transportation operation is not very convenient and flexible, and its operation and maintenance costs are also high, especially it is not suitable for harvesting some small plots or scattered plots. There are also some corn harvesters with smaller bodies, but most of them have complex structures, generally need to be equipped with special power machinery, and the production, purchase and operation costs are still high. Therefore, need to propose a kind of structure simple and applicable, with the supporting use of existing power machinery, with low cost, easy to use small-sized corn harvesting device.

Utility model content

The purpose of this utility model is to solve the above-mentioned technical problems, and propose a corn harvesting device, which is used together with hand-held or small tractors, has a simple and applicable structure, and is low in production, maintenance and operation costs, and is especially suitable for small plots and scattered fields. Chunks of corn harvested.

The purpose of this utility model is achieved through the following technical solutions: a corn harvesting device, characterized in that: a bracket is provided, a bracket is provided on the front top of the bracket, a tassel board is provided above the bracket, a The transmission chain of driving lever, sprocket wheel, guide wheel group, pull stem roller, described transmission chain is arranged on the shelling plate, is left and right two annular chains, is respectively provided with sprocket wheel, and its chain inner side is straight line, and above is arranged The driving lever is located above the middle seam of the peeling plate; the stem pulling rollers are two in parallel and arranged below the middle seam of the front end of the earing board; Transmission is connected, and described stem roller is also connected with transmission of upper transmission wheel group; Described support is fixed on the front top of walking tractor or small tractor, and described upper transmission wheel group is connected with tractor flywheel transmission.

The supplementary scheme that the utility model further improves and implements is:

It is also equipped with a lower transmission wheel set, a broken stalk box, a broken stalk shaft and a ground wheel. 1. The ground wheel is arranged on the rear bottom of the walking tractor or the small tractor, and the lower transmission wheel set is connected with the transmission right outer wheel of the gearbox of the walking tractor or the small tractor.

A grass cutting knife is arranged on the side of the stem pulling roller to remove the weeds wrapped around the stem pulling roller.

The two transmission chains arranged on the shelling plate are respectively two endless chains, which are arranged on the front and rear sides of the sprocket wheel.

A protective cover is arranged above the transmission chain.

Because the utility model is equipped with a relatively reasonable bracket, transmission chain, shelling plate, and stem pulling roller structure, the corn stalks can be accurately clamped into the middle gap between the stem pulling roller and the shelling plate during harvesting, and the ears of corn are removed and removed. It is sent into the harvesting box by the lever; the set stalk box can crush the corn stalks overwhelmed by the tractor in time, so that the stalks can be returned to the field. The setting bracket can be conveniently installed on a hand-held or small tractor, and used in conjunction with existing power mechanical equipment, which greatly simplifies the structure and reduces investment and maintenance costs. The utility model has the advantages of simple and applicable structure, low various costs, less operation and maintenance costs, and is especially suitable for harvesting corn in small and scattered plots.
