Self-propelled rice and wheat breeding harvester

Abstract

The invention discloses a self-propelled rice and wheat breeding harvester. A pneumatic conveying device of the harvester comprises a conveying fan, a collection hopper corresponding to a cleaning device, a flow guiding groove, a first corrugated hose, a second corrugated hose and a cyclone separator; the air outlet end of the second corrugated hose is connected with a switching structure with a first discharging port and a second discharging port, the switching structure is internally provided with a switching plate for switching the first discharging port and the second discharging port, andexternally provided with a control mechanism for controlling the position of the switching plate, a first connecting pipe the tail end of which corresponds to a seed reproduction box is connected tothe first discharging port, the second discharging port is communicated with an inlet of the cyclone separator through a second connecting pipe, an outlet of the cyclone separator is connected with abreeding box assembly, and the breeding box assembly is internally provided with a yield monitoring device. The self-propelled rice and wheat breeding harvester harvests bred seeds or reproduced seeds, and the breeding box assembly is internally provided with the yield monitoring device so that planting data can be more conveniently collected to provide a test basis for subsequent work.

Description

technical field [0001] The invention relates to a self-propelled rice and wheat breeding harvester. Background technique [0002] The plot test is a field comparative test of the selected crop varieties, which is an important part of agricultural crop breeding. This link has a long operation cycle, high precision requirements, and high labor intensity. Compared with field harvesting, crop harvesting in plots is very different: the area of ​​a single plot is very small; different crop varieties are planted in adjacent plots, and after each plot is harvested, the seeds in the machine must be cleaned before harvesting the next plot. to avoid mixing of different species. [0003] At present, the vast majority of experimental plots still use manual harvesting and threshing by ordinary threshers. Manual harvesting has a long harvest period, delays in farming time, low work efficiency, and large indirect losses, resulting in poor comparability of test data. However, when using o...

Problems solved by technology

[0003] At present, the experimental harvesting of most plots is still based on manual harvesting and threshing by ordinary threshers. Manual harvesting has a long harvest period, delays in farming time, low work efficiency, and large indirect losses, resulting in poor comparability of test data.

However, when using ordinary grain harvesters, there are problems such as high seed breakage rate, high loss rate, difficult internal cleaning and large seed residues, which may easily cause seeds to be mixed, resulting in distortion of test data
