Dual-layered and flexible-profiling corn picking and peeling apparatus with variable gap

Abstract

The invention discloses a dual-layered and flexible-profiling corn picking and peeling apparatus with a variable gap. The dual-layered and flexible-profiling corn picking and peeling apparatus with the variable gap comprises a left rack, a left profiling mechanism, a right profiling mechanism, a right rack, a right picking and peeling mechanism and a left picking and peeling mechanism, wherein theleft profiling mechanism is fixed under the left rack; the left picking and peeling mechanism is fixed over the left rack; the right profiling mechanism is fixed under the right rack; the right picking and peeling mechanism is fixed over the right rack; a picking and peeling amplitude angle can be formed by axes of a left picking roller and a right picking roller; a left stand column slides in aleft arc-shaped slot and a right stand column slides in a right arc-shaped slot, so the picking amplitude angle can be adjusted; a picked corn is peeled by coactions of a right propelling roller, a left peeling roller, a left profiling recessed plate and a right profiling recessed plate; and a peeling gap can be adjusted via a crankshaft rocking rod and a reset spring. Based on geometric featuresof corn ears, the picking gap and peeling gap are adjusted, so little damage is caused during the corn picking and peeling process.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a double-layer variable-gap flexible profiling corn ear picking and peeling device. Background technique [0002] Corn is one of the most important food crops in the world, and it is also one of the food crops with the most extensive planting area and the highest yield in my country. Corn not only has food uses, but also is one of the important sources of feed and fuel. The mechanized production of corn is related to the yield and quality, among which ear picking and peeling are important functions of corn machinery equipment. At present, corn harvesting machinery at home and abroad is mainly divided into two types: ear picking-peeling, ear picking-peeling-threshing, etc. Foreign corn varieties are single and planting models are single, and the technical requirements for mechanical equipment during corn harvesting are relatively low.

At present, corn harvesting machinery at home and abroad is mainly divided into two types: ear picking-peeling, ear picking-peeling-threshing, etc. Foreign corn varieties are single and planting models are single, and the technical requirements for mechanical equipment during corn harvesting are relatively low. Wide range, large climate differences, and diversified corn varieties have led to the diversification of corn planting models. It is necessary to improve the adaptability of corn harvesting machinery to agronomy.

The ear picking mechanism is related to the row spacing of corn planting, and the peeling mechanism is related to the diameter of the corn ear. The existing corn ear picking and peeling device is an independent mechanical device. The ear picking device is located at the front of the harvest, and the peeling device is located at the rear of the harvesting machine; The adjustment of the working gap is mainly by changing the gap between the ear picking boards, which directly changes the feeding width of the corn stalks, but the diameters of different corn ears are different, and the position angles of the corn ears relative to the straw after maturity are different, resulting in the failure of the ear picking boards. The gnawing on corn ears still exists; in addition, the peeling mechanism is fixed at the rear of the harvesting machine for a long time, and the harvested corn ears need to be conveyed in multiple stages before reaching the peeling mechanism, which increases the contact and collision between corn ears and mechanical parts, and improves Kernel Collision Loss
