Description
Technical field
The utility model belongs to agricultural mechanical field, and in particular to a kind of millet partly feeds sheller unit.
Background technology
Rice is China the first generalized grain crop, and the Monitoring of Paddy Rice Plant Area less than 30% but produces and accounts for about Gross World Product
40% or so grain, in the state to grow steadily, heavy rice harvesting threshing works to be made Monitoring of Paddy Rice Plant Area in recent years
Harvester, thresing machine play an important role wherein.Currently, the millet harvest in China mainly takes two ways.When
Most of region still be hand harvest after, using thresing machine carry out field on threshing；Second is that small part region is gathered in using cutter-rower,
After drying again harvesting threshing or use thresing machine direct threshing.Ye You enterprises or peasant household are using cereal such as wheat or rice in recent years
Millet harvest is carried out after combine harvester, certain modification and adjustment.But these machines mostly use full feeding form, are cut off through cutter
Stalk, branches and leaves and grain ear afterwards enters threshing cylinder threshing together, results in stalk in threshing course, branches and leaves and seed and is not easy point
Be not easy to purify from, paddy code, the problems such as entrainment loss is serious, at the same machine to the cutting of cane, roll and will also result in excessive energy
The waste of amount.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to propose that a kind of millet partly feeds sheller unit, complete feed is eliminated
The big defect of formula energy consumption, while but also entire mechanism is obviously simple, volume reduces, quality mitigates, through threshing is crushed or de-
Shell is few, detaches clean rate higher.
In order to achieve the above technical purposes, technical solution used by the utility model is：
