Raking type low-loss pickup

Abstract

The invention discloses a raking type low-loss pickup. A raking device (Figure 5) with a pickup function is used for raking and alternatively inserting windrow and conveying the windrow into an augerclose to telescopic raking teeth; two rotary discs (1) are obliquely arranged in parallel, elastic teeth are always perpendicular to a windrow direction in a movement process, and the tips of the elastic teeth are bent to a windrow advancing direction, so that the front half cycle of the rotary motion of the elastic teeth plays a stable pushing effect on the windrow, and the rear half cycle movesoppositely relative to the windrow without winding and stacking; the elastic teeth (3) are arranged on two sides of an elastic tooth fixing frame (2) in rows, so that the supporting width is increased, and a good propelling effect is achieved on the windrow; and when the elastic teeth rotate to rise, the entrained winding of the windrow can be prevented under the action of a pressing plate (5). Awalking device (9) and a profiling plate (7) both play a profiling action on the ground. During a working process, the windrow is always in a clamped and supported state, a pickup process is stable, the grain loss caused by throwing of the windrow is reduced, and meanwhile, the raking device and a header are in seamless connection, so that the grain loss is avoided.

Description

technical field [0001] The invention relates to a pick-up type low-loss picker, in particular to a two-stage pick-up device for agricultural crops, and belongs to the technical field of agricultural harvesting machinery. Background technique [0002] The two-stage mechanized harvesting can make the immature grains fully ripen after cutting down the grass shop and laying it in the field to dry for a period of time. A joint operation such as selection has a better harvest effect for crops with inconsistent grain maturity periods such as rapeseed, buckwheat, and broomcorn millet. At present, the commonly used pickers for the two-stage picking harvester are spring-toothed pickers and toothed-belt pickers. Because they have a large impact on the grain shop, they are easy to cause serious loss of picking and shattering during the picking process, which is the cause of the two-stage mechanization. An important cause of harvest loss. Based on this, the present invention has design...
