Abstract

The utility model belongs to a grain threshing machine, the design of an outlet of the existing thresher is not reasonable, blockage is easy to occur, grains and straw can not be automatically separated, and the labour intensity is increased; the utility model discloses a dual-purpose thresher, a vibration grain sieve driven by a crank is arranged to separate the grains and straw, and the grains are fallen in a conveyer at the lower part of a sieve net; crushed straw is exhausted out through an inclined sieve surface, and the grains dropped in the conveyer is directly pushed to a basket and a cloth bag which are arranged at a grain discharge port by an auger; the utility model has the advantages of simple design and light weight.

Description

The dual-purpose thresher of a kind of rice wheat

The utility model belongs to farm machinery, particularly grain threshing machinery.

It is unreasonable that thresher at present commonly used exists out mouth of a valley design, and defective such as result in blockage easily, leak causes the serious waste of paddy wheat, and millet straw can not separate automatically, increased labour intensity, and operating efficiency is lower.

The purpose of this utility model provides a kind of when carrying out grain threshing, and the grain that can will be taken off and broken grass separate, and among can automatically grain be packed into large bamboo or wicker basket, the cloth bag, automatically broken grass is discharged a kind of new thresher outside the thresher.

The technical solution of the utility model is as follows: a vibration paddy sieve that drives by crank is set on thresher; millet straw is sieved; grain drops in the conveyer below the screen cloth; broken grass is then discharged outward from the compass screen surface that tilts; the grain that falls in conveyer is pushed directly to the large bamboo or wicker basket that places out the mouth of a valley by screw feeder, among the cloth bag.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of an embodiment of the utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is a right view of the present utility model.

Among the figure: (1) grain-blocking cover; (2) threshing cylinder; (3) semicircle buting iron; (4) cylinder fixed disk; (5) bearing block; (6) thresher iron plate body of wall; (7) upper left drive; (8) power transmission shaft; (9) threshing screen cloth; (10) power wheel; (11) conveyer; (12) conveyer iron clad; (13) conveyer axle bearing; (14) iron steelframe; (15) Wooden Batten; (16) interior lower baffle plate; (17) overhead gage; (18) vibration screen; (19) vibration crank.

Threshing cylinder (2) is coaxial with upper left drive (7), and conveyer (11) is coaxial with power wheel (10), and power wheel links to each other with upper left drive with additionaling power respectively by belt.Under the drive of additionaling power, power wheel (10) and upper left drive (7) drive conveyer (11) respectively, threshing cylinder (2) rotates, the grain of hitting down is pooled in the conveyer iron clad (12) by threshing screen cloth (9), screw feeder directly pushes to out the mouth of a valley with grain, in the large bamboo or wicker basket that places in advance of packing into, the cloth bag.Upper left drive (7) is gone up a crank (19) is installed, and drives cam, and the millet straw that will be hit down on vibration screen (18) carries out vibrosieve, and grain drops in the conveyer, and broken grass is then discharged outward from the compass screen surface that tilts.

Conveyer should be made closed, the paddy wheat of hitting down all can be collected, and can not leak outside.This thresher is directly carried grain by screw feeder, and the rain or shine sky can not stop up, and millet straw realizes separating automatically by vibration screen, makes efficiency greatly improve.This machine is simple in structure, and is in light weight, is a kind of comparatively desirable dual-purpose thresher of rice wheat in present grain-producing area.

Claims

1, the dual-purpose thresher of a kind of rice wheat by frame, threshing cylinder, baffle plate, go out the mouth of a valley etc. and partly form, is characterized in that the cylinder below is provided with a screw feeder conveyer (11), can be pushed directly to the grain of hitting down the mouth of a valley that goes out of one end effectively; And above conveyer, the other vibration screen (18) that tilts that is provided with of threshing cylinder side.

2, according to the dual-purpose thresher of the described rice wheat of claim, it is characterized in that: upper left drive (7) is provided with a vibration crank (19).

3, the dual-purpose thresher of rice wheat according to claim 1 and 2 is characterized in that: be conveyer iron clad (12) below the screw feeder conveyer (11), iron clad cooperates with screw feeder is proper, and an end opening forms the mouth of a valley.
