Description

Full feed type thresher with clear grain function

Technical field

The utility model relates to a kind of thresher, particularly a kind of small-sized full feed type thresher that has separation, cleans function.

Background technology

The full feed type thresher is with respect to the semi-feeding type thresher, more saves staff, efficiency also higher.But the full feed type thresher used at present only possesses the threshing function, though most bar grass can be discharged, usually contain more more tiny stem stalk in the seed of taking off, ward off the fine impurities such as paddy and can not remove.The clear grain function such as do not possess further separation because they are many, clean, cause the seed impurity content deviate from larger, and the later stage work of cleaning comparatively bothers, and operating efficiency is also lower.

The utility model content

Given this, the utility model such as provides a kind of and has had separation, cleaned at the small-sized full feed type thresher of clear grain function, can address the above problem satisfactorily.

The full feed type thresher of the clear grain function of the utility model band; basic structure is on frame, to be provided with to drive rotation and with the threshing cylinder of threshing structure by actuating unit equally; its below connects the seed collection structure through mesh structure; there is outer cover top; and the axial direction two ends of outer cover are respectively equipped with the grass box of getting rid of of feed hopper and the large grass outlet of band, on the inwall of outer cover also with making the bar grass to the spiral guide plate that gets rid of grass box and move.In seed passage after the outlet of seed collection structure, also be provided with the air separation units of air-supply structure and the seed discharge unit after selection by winnowing.

By the seed after the usual manner threshing in the process fallen through seed collection structure outlet; the selection by winnowing of the air separation units with air-supply structure through arranging in its whereabouts passage; can be by more tiny stem stalk, ward off the fine impurities such as paddy and blow away; make seed further be separated and clean, the clean full seed after selection by winnowing is sent thresher through discharge unit again.

On the said structure basis, can also be separately or the further preferred embodiment selected of any combination mode can comprise:

The mesh structure of said threshing cylinder below, the sieve aperture that is adopted as its feed zone is greater than the form of the sieve aperture that gets rid of the grass section, the seed that both had been conducive to main threshing section sees through screen cloth, is conducive to again the discharge of large assorted outlet one side weeds, stem stalk, reduces the impurity level that enters the selection by winnowing stage.

The seed outlet of said seed collection structure below is for reducing the fillet shape contraction-like outlet of selection by winnowing air-flow through thickness, and the reducing of horizontal breadth when seed falls, be conducive to improve selection by winnowing efficiency and quality subsequently;

The air-supply structure of said air separation units can be positioned at seed passage one side of seed collection structure below, the small impurities that is provided with the band outlet in the airflow downstream side of air-supply structure on the other side is sent passage, is more conducive to the stem stalk of more tiny lightweight, wards off the fine impurities such as paddy and blow away;

Air intake oral area in said air separation units, can be provided with the air quantity adjustment structure, more convenient with use to regulate the air output of selection by winnowing according to reality, to guarantee to eliminate the foreign material of more tiny lightweight contained in seed, and prevent that air quantity is excessive and blow away seed;

Seed discharge unit after said selection by winnowing, can comprise the seed feeder that is provided with screw conveying structure, and send channel attached collection structure at the collecting terminal of seed feeder with the orbiting vane feeding structure and with seed;

On the rotating vane of the orbiting vane feeding structure in said collection structure, can further be connected with as flexible material pads such as rubber, plastics, to be reduced in driving mechanism, drive the destruction of the blade of lower High Rotation Speed to the seed generation;

Above-mentioned said collection structure wall section (comprising that surrounding wall or top/bottom etc. are respectively to sidewall), also be provided with the portable plate that can open/close, the cleaning while to facilitate, feed blocking occurring;

Said threshing cylinder can adopt on the outer wall of rotatable cylindrical structure circumferentially uniformly-spaced arrange vertically or oblique extension with the threshing rack structure of spike-tooth type threshing structure, be conducive to the to the greatest extent de-of seed, minimizing is with discharging that the bar straw cord is walked and the seed that loses, also reduced the fragmentation of weeds and stem stalk, thereby reduced the content of bringing the fine impurities in seed into simultaneously;

The outer cover of said threshing cylinder top, can be adopted as the openable structure that a side is connected with frame through hinge, more is conducive to the operations such as cleaning, maintenance and replacing parts to machine.

This shows and understand that the full feed type thresher of the clear grain function of the band of the utility model said structure has separation, the clear grain function such as cleans; and separating power is strong; can obtain cleaner seed, efficiency is high, and grain loss is little; save the advantages such as manpower; and simple in structure, volume is little, working service is convenient; applicable to the threshing of the crops such as paddy rice, wheat, rape, be particularly suitable for the less medium and small user of knob and staff and use.

Below in conjunction with the embodiment by the accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as to the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the utility model, various replacements or the change according to ordinary skill knowledge and customary means, made, all should be included in scope of the present utility model.
