Description
Technical field
The invention belongs to agricultural machinery equipment field, and in particular to receive grain device in a kind of adjustable threshing ground.
Background technology
Grain-production is always in occupation of the main status of China, during the busy farming season, and peasant household is by after grain harvest, in order to remove grain
In moisture, prevent grain because mildew is gone bad containing excess moisture, people are always spread out in grain on threshing ground and dried, and wait to shine
Generally collected by hand after dry and load grain sack (i.e. with spade or scoop, by hand collecting crops), the problem of it brings is not only
Labor intensity is big, and it is very low to receive grain efficiency.When running into mutation weather, grain may be caused because having little time to collect grain
Food is drenched with rain.With the development of mechanization of agriculture, grain efficiency is received to threshing ground and proposes higher requirement, and existing receipts grain device is all
It is, using large tractor driving, to receive grain inefficient, cumbersome, the particle spoilage to grain is big, it is difficult to widely use, because
This, a kind of letter novel adjustable to be studied is light to receive grain device.At present, grain device is received on threshing ground of the in the market without adjustable portable,
This device is simple to operate, can adjust the car body speed of travel according to the drying thickness of grain, receive grain efficiency high, it is adaptable to medium and small
Receive grain in the threshing ground of type peasant household.
The content of the invention
The purpose of the present invention is to overcome drawbacks described above there is provided one kind is applied widely, and can be according to the drying of grain
Thickness receives grain device to adjust the adjustable threshing ground of the car body speed of travel, mitigates hand labor intensity, realizes that high efficiency receives grain.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of adjustable threshing ground is provided and receives grain device, bag
