Description

Towed small-sized wheat thresher

One, technical field: the utility model relates to a kind of towed small-sized wheat thresher.

Two, background technology: the thresher of Shi Yonging mostly is combined harvester and small-sized suspension type thresher etc. greatly now; though the combined harvester technology maturation because of its volume is bigger, is not adapted at operation in the farmland, fritter forest belt; and its cost is higher, the unable purchase of common peasant household.Small-sized thresher then because of its threshing is unclean, wheat straw mixes, makes threshing efficiency low, the requirement of not satisfying peasants and herdsmen's feeding quality and reducing labor intensity.

Three, summary of the invention: the purpose of this utility model be to people provide a kind of can operation in farmland, fritter forest belt, the towed small-sized wheat thresher of through threshing.

The purpose of this utility model is achieved in that towed small-sized wheat thresher comprises the base of seat on the chassis; be fixed on the coconnected threshing chamber of base, Primary Room and Selected Room; be equiped with road wheel on the chassis, chassis front end connects hitch frame, and is whole by other agricultural machinery tractions such as little four-wheels.Threshing cylinder, screen cloth and baffle plate are set in the threshing chamber, and its below is communicated with Primary Room.Be provided with I and II screen cloth and fan in the Primary Room, auger is laid in the bottom, is provided with lifter in the auger side of gathering materials, and discharging place of lifter top is communicated with defeated material passage, and defeated material passage is communicated with Selected Room, and screen cloth is set in the Selected Room.

Owing to carry out technique scheme, the utility model is to broken flat wheat straw, threshing and clean etc. that operation is disposable to be finished, and flexible operation, threshing quality are good.The content of wheat straw broken soft back length about 40mm is greater than 70%, and the threshing total loss rate is less than 2.0%, and the seed damage rate is less than 1%, and cleannes are greater than 90%, but threshing 900kg has per hour solved numerous peasants and herdsmen's scarce feed, the problems such as labour intensity is big of threshing grain.This machine also can carry out threshing to draft crops such as rape, flax, safflowers, and is applied widely.

Four, description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
