Description

Thresher for wheat

The utility model relates to the improvement to the wheat thresher.

In agricultural production, be an onerous toil to harvested wheat threshing, the somebody is in order to save trouble in the rural area, wheat under the harvesting directly is layered on the highway, appoints with car stone roller people and step on, adopt this method threshing, not only waste grain, influence the grain health, and can produce traffic accident.The agricultural machinery factory once produced and a kind ofly obstructed the wheat thresher that machine into carries out threshing with the chain wheat of carrying under one's arms, and was former thereby not popular to people because of its complex structure, motor power (output) need 3.5～10 kilowatts, operating personnel are many, cost is high etc.An existing grow wheat thresher is that the wheat head and wheat stalk are all put into the machine threshing or earlier the machine threshing put in wheat head cutting-out, and its motor power (output) also needs 2.5～3.5 kilowatts, and not only efficient is low, energy loss big but also cost is higher.In addition, the direction of rotation of its stripper wheel of wheat thresher that uses is towards operating personnel at present, and under action of centrifugal force, a large amount of dust and wheat straw slag are dished out from wheat inlet, cause serious air pollution, directly endanger health of operators.Existing wheat thresher does not have wheat, wheat husk separator, increases a lot of amounts of labour and trouble to the user.

The purpose of this utility model provides improved wheat thresher, and its motor power consumption is little, efficient is high, wheat and the automatic sorting of wheat husk, and cost is low, helps health of operators.

The purpose of this utility model is achieved through the following technical solutions.

Wheat thresher described in the utility model; organic frame and threshing chamber; stripper wheel is installed in the threshing chamber; the threshing tooth is housed on the stripper wheel; between stripper wheel and the stripper wheel electromotor by the belt pulley transmission; the threshing chamber antetheca has wheat inlet; it is characterized in that; the wheat straw slag outlet is arranged at threshing chamber rear wall top; fixedly threshing tooth is installed in the threshing chamber rear wall, and the bottom of threshing chamber is mesh wheat sieve, the bottom of threshing chamber and poly-grain chamber top attachment; poly-grain chamber is funnel-form; the wheat leaking opening of bottom, poly-grain chamber inserts in the grain shell separation chamber, and a side of grain shell separation chamber is equipped with fan, and opposite side is equipped with shell discharging pipe; the bottom of grain shell separation chamber has out Mai Kou, wheat leaking opening and go out the Mai Kou place and be provided with the tongue that keeps out the wind respectively.

The utility model design preferably is that the fixedly threshing tooth bar of strip tilts to be installed on the threshing chamber posterior inferior wall slightly, and the threshing tooth on the stripper wheel is not met with fixing threshing tooth simultaneously, guarantees that induction-motor load is more even.Save the energy, reduce power consumption.

The better design of the utility model is that fans connects with the stripper wheel motor reel.

The more perfect design of the utility model is that shell discharging pipe is bent upwards and connects with frame, is respectively equipped with plate washer in the thresher front and back.

With reference to the accompanying drawings the utility model is done and described in further detail.
