In order to overcome existing farm storage storehouse capacity too little (being 22 cubic metres to the maximum), Prevention of Mould Development unstable properties (the grain storehouse depth of grain layer reaches more than the 1.5m), grain natural-draft drying efficient is low in the storehouse, conveying grain into storehouse delivers from godown low by artificial conevying efficiency, the large deficiency that waits of labour intensity, the invention provides a kind of compartment ventilation grain bin, this compartment ventilation grain bin capacity is large---and 120 cubic metres, grain storage is the ventilating duct compartment in the storehouse, can be according to peasant household's demand spreading on the basis of basic storehouse type, the seriation of capacity specification also can be satisfied the demand of different peasant households, and the grain realization mechanical work that goes out to put in storage improves work rate.

The technical solution adopted in the present invention is: a kind of compartment ventilation grain bin is connected by front little storehouse group and rear little storehouse group and forms, each little storehouse group is connected by 8 little storehouses and forms, be provided with the ventilating duct of certain ventilation between the little storehouse, increase the circulation of air of grain interlayer, establish main air duct between front little storehouse group and the rear little storehouse group, main air duct is comprised of cat ladder and pedal, form the ventilation grain bin of 120 cubic meters capacity, the basic storehouse of grain storehouse type is long to be 6m, little storage grain thickness is 1m, by increasing and decreasing the quantity in independent little storehouse, subtract the purpose of appearance to reach dilatation.

The invention has the beneficial effects as follows, its main design objective of compartment ventilation grain bin is as follows:

1, capacity is 120 cubic metres;

2, grain storage kind: the grain such as corncob, iblet, paddy, soybean grain;

3, the grain moisture content that puts in storage :≤28%(11 month), 28% above moisture content needs put in storage in mid-December;

4, the grain proportion of goods damageds :≤1%;

5, the shelf time primary fragmentation rate that goes out to put in storage increases≤0.5%;

6, the protection against rodents sparrow stings the food rate: 100%;

7, moldy kernel increases in the grain storage cycle: nothing;

8, grain fat value increases≤1% in the grain storage cycle.

Above index is all up to standard through at present actual measurement, and the present invention is suitable for the main product grain provinces and regions such as China three provinces in the northeast of China and Inner Mongolia Autonomous Region and Henan, Hebei, Shaanxi and uses.
