Abstract

The utility model relates to a threshing machine which comprises a feed hopper, an outer cylinder, a threshing roller and a machine frame. The threshing machine is characterized in that an upper cambered sieve plate and a lower cambered sieve plate are arranged in the outer cylinder, are provided with sieve holes, and are combined into a sieve cylinder, and a cavity channel is arranged between the sieve cylinder and the outer cylinder. The utility model has the advantages of that the threshing efficiency is improved by more than 30 percent, the work resistance is reduced, the motor power is reduced, and the production cost can be reduced without generating work overload phenomena.

Description

Thresher machine

Technical field

The utility model belongs to a kind of agricultural machinery, particularly a kind of crops thresher machine.

Background technology

Existing crops thresher, for example horizontal husker sheller mainly is provided with the threshing tube of bringing hopper into, in the threshing tube grain threshing roller is installed, and is provided with many sieve apertures in the Lower Half of threshing tube, and the curved sieve plate shape of Lower Half is provided with the end sieve of inclination in its lower section.During work, corn ear drops in the threshing tube, and by the grain threshing roller threshing, iblet sifts out from the sieve aperture of threshing tube Lower Half.There is following deficiency in this structure that sieve aperture is set in threshing tube Lower Half: threshing efficiency is restricted, more for a long time, working resistance is bigger at the material that drops into threshing, once overload is serious, the easy burn-out motor then needs more powerful driven by motor in therefore using.

The utility model content

The purpose of this utility model provides a kind of thresher machine, improves threshing efficiency, reduces working resistance, is difficult for overload, reduces power of motor, reduces production cost.

The purpose of this utility model is achieved in that it comprises the arc lower sieve plate and the frame of feed hopper, urceolus, grain threshing roller, band sieve aperture, it is characterized in that: last arc screening plate and arc lower sieve plate that the band sieve aperture is set in the urceolus, last arc screening plate and arc lower sieve plate are combined into screen drum, between screen drum and the urceolus cavity are set.

The utility model has the advantages that: improve threshing efficiency more than 30%, reduce working resistance, no operating overload phenomenon reduces power of motor, and same output adopts 3 kilowatt motors in the past, and the utility model then adopts 2.2 kilowatt motors to get final product, and reduces production cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is A-A cutaway view of Fig. 1.

Embodiment

See Fig. 1,2, concrete structure of the present utility model is as follows: urceolus 4 is installed on frame 1, and urceolus 4 is made of upper and lower half assembling.Second tube is provided with iblet outlet 10.The last arc screening plate 5 and the arc lower sieve plate 7 of band sieve aperture are set in the urceolus 4, and last arc screening plate 5 is combined into screen drum with arc lower sieve plate 7, and the outlet of feed hopper 3 inserts in the screen drum.Grain threshing roller 6 rotating group are contained on the frame 1, and grain threshing roller 6 is positioned in the middle of the screen drum, between screen drum and the urceolus 4 cavity 13 is set, be convenient to the iblet that sifts out through last arc screening plate 5, arc lower sieve plate 7 along the cavity landing to iblet outlet 10.The end sieve 11 of inclination is set, so that the impurity in the corn is sieved below iblet outlet 10.Corncob cellulose outlet 9 is set, at the inboard of outlet assembling vibratory sieve 8 at the rear portion of screen drum.At a side of urceolus 4 assembling blower fan 12, set out air port 14 at the opposite side of urceolus 4.With blowing out from air outlet in the iblet than light impurity.Assembling transmission device 2 on frame, transmission device 2 drives grain threshing roller 6 and rotates.

The utility model is equally applicable to the shelling of fibert fruit.

Claims (1)

1, a kind of thresher machine, it comprises feed hopper, urceolus, grain threshing roller and frame, it is characterized in that: the last arc screening plate and the arc lower sieve plate of band sieve aperture are set in the urceolus, and last arc screening plate and arc lower sieve plate are combined into screen drum, between screen drum and the urceolus cavity are set.
