Abstract
The invention discloses a multi-functional bionic corn thresher which comprises a rack, a threshing cylinder, a threshing sieve, a sieve plate and a belt pulley, wherein the belt pulley is connected with the threshing cylinder; the rack is composed of an upper shell and a lower frame which are matched, and the upper shell is provided with a first feed inlet and a second feed inlet; the axial circumferential surface of the threshing cylinder is provided with a chicken beak-shaped kernel driving lever; and the threshing sieve is provided with a chicken beak-shaped threshing lever. The corn thresher disclosed by the invention can satisfy the threshing needs of corn kernels with different uses; and according to the principle of bionics, a threshing unit (such as teeth or striking ribs) on the cylinder is designed into the shape of a wedge-shaped beak part of a chicken, so that an effect of loosing clusters and then threshing the clusters can be achieved, thereby greatly reducing the damages on corn kernels during threshing.
Description
Technical field
The invention belongs to agricultural mechanical field, relate in particular to a kind of Multi-functional bionic corn thresher for corn threshing.
Background technology
Corn is not only one of the Three major grain crops in China and even the world, corn threshing is the key link in harvesting work, it has determined the damaged degree of corn kernel, the shelf life of corn kernel can be subject to the impact of seed damaged degree, suffer that damaged corn seed germination rate is low, the easy bacterium, infested, easily broken of mildewing, and reduced its market value and export value.
Existing cylinder corn sheller is to adopt high speed impact principle to carry out corn threshing; threshing cylinder is the core component of thresher; threshing cylinder High Rotation Speed in threshing course; the bossing of its outer rim (spike-tooth or impact muscle etc.) applies strike effect to corncob, makes corn kernel separated with corn mandrel.Drum rotation speed more than 700r/min, cylinder outer rim etc. to be greater than the linear velocity of 8m/s, directly act on corn kernel, by high-speed striking, realize threshing, but impact the spike-tooth on process intermediate roll or impact muscle very large to corn kernel damage, therefore, this corn kernel can only be used in the aspects such as flour, feed processing.At present; also having a kind of is differential speed type husker sheller; the drum rotation speed of this thresher is slower; during to corncob threshing, have that corn kernel percentage of damage is low, threshing performance is high; corn kernel is commonly used in needs storage, transportation, seed processing aspect; but it is not very large that this differential thresher reduces the amplitude of the percentage of damage of corn kernel, and its drum rotation speed is slower, causes operating efficiency lower.
According to noted earlier, mainly there is following deficiency in existing husker sheller: in (1) corncob threshing course, the threshing damage ratio of corn kernel is not stopped or significantly reduced; (2) act on singlely, each thresher only can carry out a kind of seed threshing of form to corncob, and the threshing as high in seed damage rate, threshing efficiency is high, for aspects such as flour, feed processing; And the threshing that seed damage rate is low, threshing performance is high, for aspects such as needs storage, transportation, seed processing.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of Multi-functional bionic corn thresher for corn threshing, can meet the threshing needs of the corn kernel of different purposes; And according to bionics principle, the threshing unit on cylinder (as spike-tooth or impact muscle etc.) is designed to the shape of the wedge shape beak portion of chicken, can realizes the loose threshing again of elder generation of fruit ear, thereby the damage to corn kernel while greatly reducing threshing.
In order to realize foregoing invention object, the present invention adopts following technical scheme:
A kind of Multi-functional bionic corn thresher, comprise frame, threshing cylinder, threshing screen cloth, sieve plate and the belt pulley being connected with threshing cylinder, described frame is comprised of the upper shell matching and underframe, on upper shell, be provided with the first spout and the second spout, on underframe, be provided with corncob outlet and seed outlet, threshing cylinder two ends are movably arranged in upper shell by bearing, on the external peripheral surface of threshing cylinder, be provided with the seed driving lever of beak shape, described threshing screen cloth is arranged on the side of threshing cylinder, and threshing screen cloth both ends are all bolted on upper shell, thrashing screen is provided with the threshing bar of beak shape on the net, between threshing bar and seed driving lever, form cylinder-concave clearance, the initiating terminal of cylinder-concave clearance is positioned at the outlet below of the second spout, the end of threshing working space is provided with sieve plate, the end of sieve plate is connected with corncob outlet.
Described Multi-functional bionic corn thresher, its seed driving lever is a plurality of, and is evenly distributed on the external peripheral surface of threshing cylinder.
Described Multi-functional bionic corn thresher, is provided with collection baffle plate in its underframe, collect baffle plate and be positioned at described threshing screen cloth and the below of sieve plate, and the end of collection baffle plate is connected with seed outlet.
Described Multi-functional bionic corn thresher, is bolted to connection between its upper shell and underframe.
Described Multi-functional bionic corn thresher, its threshing screen cloth is to be composed of a fixed connection by screw by a plurality of horizontal notch boards and a plurality of longitudinal notch board.
Owing to adopting technique scheme, the present invention has following superiority:
1, can meet the corncob threshing that corn kernel is had to different purposes demands, when corncob carries out threshing from the first spout feeding, the percentage of damage of corn kernel is low, threshing performance is high, is applicable to need the aspects such as storage, transportation, seed processing; When corncob carries out threshing from the second spout feeding, the percentage of damage of corn kernel is high, production efficiency is high, is applicable to the aspects such as flour, feed processing.
2, by drawing in the bionical discrete analysis of experiments of corn kernel that chicken is pecked at---the wedge shape beak portion of chicken not only has the ability of the discrete seed in seed gap of good incision corncob, also has stronger pecking and gets seed ability; Thus, threshing unit on cylinder (as spike-tooth or impact muscle etc.) is designed to the beak portion shape of chicken, in threshing course, first beak shape threshing unit is cut and on corncob, between seed, is carried out that seed is loose then carries out seed threshing again, the percentage of damage that greatly reduces seed, has improved threshing performance.
3, between fixing threshing screen cloth and the threshing cylinder of rotation, formed the threshing of single roller differential, the damage to corn while having reduced threshing, has reduced seed damage rate.
