Description

A small double-roller corn thresher

technical field

The invention relates to the technical field of agricultural machinery, in particular to a small double-roller corn thresher.

Background technique

Corn threshing is the final step of corn harvesting. If the corn cobs after peeling and drying cannot be threshed in time, the corn will often germinate or rot due to weather, which seriously reduces the use value and economic value of corn. The traditional method of corn threshing is to grind corn by hand, use a tool called a corn drill to hold the corn cob tightly with one hand, and use the corn drill to push forward at a point on the corn cob with the other hand. Generally, a corn is drilled at least three to four times. , and then grind the remaining corn with both hands. After a long time of grinding, the fingers are prone to foaming, which is not only time-consuming and laborious but also inefficient, and is not suitable for large-scale corn threshing. With the development of agricultural machinery, many large-scale corn threshers came into being. However, due to the high cost of corn thresher, corn kernels are easy to break, and the waste is serious, so the utilization rate is low. The small corn threshers currently emerging mostly use single-roller threshing operations, which still cannot meet the large-scale threshing operations; the exposed rotating gears and conveyor belts are very easy to cause shutdown or safety hazards due to accidental collision; it is inconvenient to use support frames to touch the ground. handling and adjustments.
