Abstract

The utility model relates to a corn ear picking device which utilizes the height difference from the positions of corn ears to the ground. An ear picking roller (3) is arranged horizontally at a height a little lower than the positions of corn ears, a cutter (2) is arranged on the front-lower part of the ear picking roller, and a curved runner (4) is arranged below the ear picking roller. Therefore, when entering the ear picking roller, corn stalks sent by a stalk lifter (1) are cut off immediately by the cutter at a higher position and pulled downwards rapidly. Because the cutting position is relatively high, and the curve radius of the runner is relatively large, the stalks which are pulled down are easy to be changed of directions along the runner. After the direction changes 90 DEG, the stalks are thrown out along the horizontal direction, and the corn ears are picked during the course when the stalks are pulled down; the ears are easy to be collected as well.

Description

A kind of ear-snapping unit

The utility model relates to a kind of mechanical harvest device of corn, belongs to agricultural mechanical field.

At present, ear-snapping unit has all utilized ear harvesting stick, and ear harvesting stick is divided into two kinds of upright rod formula and rod formulas for sleeping in.Upright rod formula ear-picking unit is from root corn stem to be cut off earlier by cutter, by clamping device cane is sent into ear harvesting stick again and plucks fringe.Its complex structure.The rod formula ear-picking unit that crouches does not cut off corn stem, directly plucks fringe by ear harvesting stick, and cane can not directly reclaim, the spike collecting inconvenience.

The purpose of this utility model: provide and to cut off corn stem, do not need the ear-picking unit of clamping device again.And fruit ear is collected easily.

The purpose of this utility model is achieved in that because there is certain height the knot fringe position of corn far from ground, thus with the ear harvesting stick horizontal setting in the higher position.Generally below knot fringe position 10 centimetres get final product.So the bigger blade fin of a radius of curvature can be set below ear harvesting stick.Purpose is, makes the cane after the cut-out be relatively easy to change direction along the curve slide plate.When 90 ° of direction changes, when just cane becomes the horizontal level state.Cane is easy to be dished out.Cutter is installed in the front lower place of ear harvesting stick.After making corn stem one enter ear harvesting stick, be cut off in the higher position immediately.One end of curve slide plate links to each other with cutter, makes the cane after the cut-out can enter slide plate, and an end of slide plate as far as possible backward, place downwards, and is bent through radius to increase.Generally apart from 1.5 meters of cutters, overhead 10 centimetres.Like this, after corn stem enters ear harvesting stick by rod righting device, be cut device immediately and cut off, and pulled to the below by ear harvesting stick rapidly.Because cane can only slide on the curve slide plate, force it to change direction.After direction changed 90 °, the cane along continuous straight runs was dished out backward.Fruit ear is won in the process that cane is left behind.Because ear harvesting stick is a horizontal positioned, and the position of placing is higher.The fruit ear of taking is easy to fall into lower maize cob collector, is convenient to collect.Higher root stubble chopping and returning.

Owing to adopt such scheme, clamping device can not cut off cane earlier yet, plucks fringe again.Simple in structure, fruit ear is collected easily.

Figure one is a schematic diagram of the present utility model.

Figure two is schematic diagrames of the utility model embodiment.

Among the figure 1, rod righting device 2, cutter 3, ear harvesting stick 4, curve slide plate 5, elevator 6, container 7, trailing wheel 8, engine 9, maize cob collector 10, driver's seat 11, front-wheel and steering handle

In figure one, being cut device (2) immediately after corn stem is sent into ear harvesting stick by rod righting device (1) cuts off in the higher position, cane after the cut-out is pulled to the below rapidly by ear harvesting stick (3), because ear harvesting stick (3) below is provided with the bigger slide plate of radius of curvature (4), the cane of being left behind is dished out after changing direction from behind.

This device is installed in just forms a small-sized self-walking maize harvesting machine on the three-wheel running gear, shown in figure two, fruit ear is won in the process that cane is pulled down by ear harvesting stick, and falls into maize cob collector naturally (9), is transported into container (6) by elevator (5) again.

Claims

1, a kind of ear-snapping unit, rod righting device, cutter, ear harvesting stick are installed successively, it is characterized in that: ear harvesting stick horizontal positioned, cutter are installed in the ear harvesting stick front lower place, and the ear harvesting stick below is provided with the curve slide plate.

2, ear-snapping unit according to claim 1 is characterized in that: the height of ear harvesting stick horizontal positioned is 10 centimetres of belows, knot fringe position.

3, ear-snapping unit according to claim 1, an end that it is characterized in that the curve slide plate be at the cutter place, and the other end is apart from 1.5 meters of cutters, overhead 10 centimetres.
