Description

Full-feed grid type lodging corn ear picking header

technical field

The invention relates to a corn harvester, in particular to a cutting table for a corn harvester that uses a full-feeding method to send lodging corn plants into an ear-picking mechanism, and uses a grid-shaped ear-picking mechanism to complete corn ear picking. The invention belongs to agricultural machinery field.

Background technique

Ear picking is a key link in corn mechanized harvesting, and reducing picking losses plays an important role in ensuring the return of grains to the warehouse and ensuring food security. Mechanized picking of lodging corn ears is a difficult and painful problem that needs to be solved urgently in corn harvesting. From the end of milk ripening to the early wax ripening of corn growth, the kernels tend to mature. When encountering disasters such as strong winds and heavy rainfall, lodging is very easy to occur. The lodging that occurs at this time has little impact on corn yield, but the plants are scattered on the ground. , causing the ear position to be lower than the effective ear picking height of the header, the corn harvester header cannot complete the ear picking action, resulting in a large number of ears remaining at the bottom of the header, resulting in landing losses. Studies have shown that for every 1% increase in the lodging rate, the loss rate of machine-harvested ears will increase by 0.17% to 0.28%. At the same time, lodging disrupts the orderly distribution of stalks formed after corn planting with "fixed row spacing and uniform plant spacing", making it difficult for the harvester to line up, and the feeding of corn plants and other materials on the cutting table is disorderly and disorderly, in addition to causing fruit ears. In addition to the loss of grains, the header will be blocked due to the excessive feeding of the instantaneous straw, resulting in a sharp drop in harvesting efficiency.

At present, for the harvest of lodging corn, it is generally used to reduce the operating speed of the harvester and the height of the header to pick the ears. On the one hand, this operation method greatly reduces the harvesting efficiency. conditions resulting in substantial ear and kernel loss. For severe lodging corn, relevant practitioners invented and designed lengthened grain lifters, non-aligned headers, auxiliary feeding mechanisms for rotary harrow teeth, and auxiliary lifting mechanisms for stems with spiral auger types to elevate the position of ears of lodging corn and the stalks on the ground. Auxiliary feed to header. However, the above-mentioned mechanisms are all improved designs based on the traditional corn harvester header, which are limited by the header structure and cannot fully adapt to different corn lodging forms, and there are certain structural defects in operation.

To sum up, for severe lodging corn, it is necessary to invent a special lodging corn ear harvesting platform for the different lodging forms of corn to solve the technical problem of lodging corn ear picking.
