Abstract

The utility model discloses a multifunctional thresher which is mainly composed of a frame which is provided with a motor, a casing which is provided with a feed hopper and a discharge hopper, a threshing sieve and a threshing cylinder which is arranged in a sloping way with a horizontal plane. Materials which to be threshed can move forwards by means of gravity, the flowing property of the materials can be improved obviously, the threshing pressure can be reduced, the number of crushed particles is reduced and the serviceability rate for threshed products is improved. The utility model has the advantages of novel idea, simple structure, small size and convenient operation and use. Besides, the utility model can be respectively used for threshing and processing various crops, such as corn, ears of wheat, ears of rice, etc., therefore the use function is widened.

Description

Multi-functional thrasher

Technical field:

The utility model relates to grain threshing processing equipment, belongs to agricultural machinery technological field, and it is a kind of multi-functional thrasher, is particularly suitable for peasant family and is used for crops such as corn, the wheat head, spike of rice are carried out the threshing production operation.

Background technology:

In recent years, high speed development along with Chinese national economy, particularly country is to the great attention of agriculture, rural areas and farmers problem, greatly advanced the fast development of China's agricultural machinery cause, at present, in Pingba agricultural district, vast Plain, generally use combine to gather in, the threshing production operation, this has all brought into play positive effect to the labour intensity and the raising harvesting threshing production efficiency that alleviate vast farmers, this combine has the mechanization degree height, the functional strong and harvesting threshing operations efficient advantages of higher of production operation, but this combine can only gather in the threshing production operation in Plain Pingba agricultural district.And in the vast mountain and hill agricultural district of China, owing to be subjected to the limitation of geographical environment, promoting the use of of large-scale agricultural machinery is restricted, just present, when vast crops such as mountain and hill agricultural district harvesting corn, paddy rice and wheat, still mostly be to continue to use traditional manual threshing operations mode, the original backwardness of this manual threshing mode of production, labour intensity is very big, efficient is extremely low, has seriously restricted the development of this area's agricultural economy.Though also occurred some threshing machines recently; but present employed thresher exists some technical bugs; main performance is that the threshing cylinder of existing thresher is to arrange by horizontal mode to install entirely; when crops are carried out threshing operations; it is mobile to be relied on threshing cylinder to push fully by the material of threshing; relatively poor by the material of threshing mobility in thresher; cause threshing pressure sharply to increase; therefore not only increased power consumption; but also increased particle quantity; reduced the whole grain serviceability rate of threshing product; have a strong impact on the threshing quality of thresher; and the volume of existing thresher is bigger; the threshing function is very single, has certain limitation in actual use.

The utility model content:

The utility model be propose on the basis of existing technology a kind of simple in structure; volume is small and exquisite; production cost is low; easy to manufacture; multi-functional thrasher easy for operation; it is particularly suitable for single peasant family and uses; can be to corn; the wheat head; multiple kinds of crops such as spike of rice are carried out threshing processing operation; it is achieved by the following technical solution: it is mainly by frame; be provided with feed hopper; the casing of discharge bucket; thrashing screen and threshing cylinder constitute; it is characterized in that: the spindle centerline of threshing cylinder and the inclined angle alpha of horizontal plane are 45 ° of 5 ∽; when crops are carried out threshing operations; enter can be moved forward by gravity in the casing by feed hopper by the material of threshing; can obviously strengthen by the mobile performance of threshing material in thresher; reduce threshing pressure; improve the whole grain serviceability rate of threshing product, improve the threshing quality.

The utility model also has following technical characterictic:

Threshing cylinder is made coniform, by spirality is arranged evenly one group of threshing rib is arranged on coniform threshing cylinder surface, is particularly suitable for corn ear is carried out threshing processing operation.

Threshing cylinder is made cylindric, there is one group of threshing to bend tooth on cylindric threshing cylinder surface by spirality is arranged evenly, the control helixangle is 40 ° of 10 ∽, the angle of deviation γ of control threshing bow tooth is 15 ° of 5 ∽, be particularly suitable for the spike of rice or the wheat head are carried out threshing processing operation, on the threshing kind, widened function of use.

Embodiment:

The multi-functional thrasher that the utility model proposes is implemented as follows: it is mainly by electromotor 2 is installed; driving belt 3; the frame 1 of bearing block 4; be provided with feed hopper 6; the casing 7 of discharge bucket 11; thrashing screen 10 and threshing cylinder 8 constitute; be 25 ° by the inclined angle alpha of main shaft 5 center lines of the threshing cylinder 8 of bearing block 4 supporting and horizontal plane fabulous threshing effect is arranged; can adopt the threshing cylinder of different structure shape according to the different cultivars of institute threshing crops; for example; in the time of will carrying out threshing to corn ear; can make threshing cylinder 8 coniform; press spirality one group of threshing rib 9 arranged evenly on coniform threshing cylinder 8 surfaces; in the time of will carrying out threshing to spike of rice or the wheat head; threshing cylinder 8 can be made cylindric 13; it on cylindric threshing cylinder 13 surfaces is one group of threshing of helical pattern bow tooth 12 of 20 ° by helixangle; the angle of deviation γ of control threshing bow tooth 12 is 7 °; good threshing effect is arranged; it is work like this: actuating motor 2 drives threshing cylinder and rotates; enter can be moved forward by gravity in the casing 7 by feed hopper 6 and carry out threshing by the threshing material; corncob after the threshing or fringe slag are discharged from casing 7 bottoms, and the material of taking off is discharged pack by discharge bucket 11 and got final product after thrashing screen 10 sieves.
