Abstract
The present invention discloses a miniature rice and wheat combine harvester which is suitable for paddy fields with different topographical features. The combine harvester is composed of a grain stripping wheel, a cutting device, a conveyor chain, a threshing mechanism, a sorting mechanism, a connecting and lifting mechanism and a power input mechanism, wherein the conveyor chain is composed of two chains which are parallel and are provided with hook teeth at chain surfaces; a threshing part of the threshing mechanism is composed of a flat plate structure of which the track (wide chain) is provided with a plurality of arc teeth on the surface. The combine harvester has the advantages of simple and compact structure, small volume, light weight, low power consumption, low cost, low price, reliable operation, easy operation, high receiving rate and strong maneuverability. Besides, the present invention can be suitable for the combined harvest of wheat and rice in paddy fields with different topographical features.
Description
Affiliated technical field
The present invention relates to a kind of miniature rice-wheat combine harvester that use in China south that is suitable for.It is applicable to harvesting and the threshing of wheat, paddy rice and other crops.
Background technology
Existing rice/wheat combine can be divided into horizontal, vertical and the disk swinging.Most of combines can only adapt to the vast northern getting wheat of China's field soil, and incompatibility China field soil is narrow, the southern harvester for rice wheat that soil property is soft.The combine that also has a kind of imitated Japan in addition on the market, though its volume is less, complex structure also can adapt to southern little field piece operation, but price is very expensive, and vast farmers can't bear, and therefore also is difficult to promote the use of.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, and provide a kind of simple in structure, volume is little, in light weight, power consumption is little, cost is low, low price, reliable operation, processing ease, net harvesting rate height, mobility strong can be adapted to the miniature rice-wheat combine harvester that little field piece uses.
The objective of the invention is to reach by following technical measures: this miniature rice-wheat combine harvester by seedling regulating wheel, cut cutter, carrier chain, separating mechanism, sorting mechanism, feed mechanism, connection elevating mechanism and power input mechanism and form.Wherein carrier chain by two parallel to each other and toothed chain form, and these two parallel and toothed chains one are within the separating mechanism; The threshing of separating mechanism partly is provided with the slab construction of some arc teeth on the surface by crawler belt (wide chain) and forms.Be provided with the ratchet that 2 anti-straws stop up simultaneously in the straw porch of separating mechanism.In separating mechanism, the top that is positioned at carrier chain also is provided with the adjustable spring grain pressing rod in addition; Sorting mechanism is made up of piano-wire screen, broad width conveying belt, blower fan and hopper.Piano-wire screen be positioned at separating mechanism below.And broad width conveying belt is positioned at 50～80mm place below the piano-wire screen.The air outlet of blower fan is between broad width conveying belt and hopper; Feed mechanism is made up of screw spreader that is positioned at hopper and the centrifugal Material sucking machine that is positioned at the hopper outlet place.
Two the residing planes of toothed parallel chain in the carrier chain of the present invention and the angle of horizontal plane are 8 °～10 °.

Embodiment
The present invention will now be further detailed embodiment: this miniature rice-wheat combine harvester by seedling regulating wheel 4, cut cutter 2, carrier chain 3, separating mechanism 6, sorting mechanism 10, feed mechanism 18, connect elevating mechanism 8 and power input mechanism 16 is formed.In the middle of this, can arrive oscilaltion and elastic by the support bar above it along standing grain 4; Cutting cutter 2 is to adopt the common reciprocating type cutter of cutting; Carrier chain 3 is made up of two toothed chains, and the parallel to each other and angle that plane that form is become with horizontal plane of these two chains is 8 °～10 °, and these two parallel chains one are through to the inside of separating mechanism 6; The porch of separating mechanism 6 is provided with the ratchet 5 that 2 anti-straws are stopped up.The threshing of separating mechanism 6 partly is that the slab construction that some arc teeth constitute a kind of operating type is set on the surface of crawler belt (wide chain).In addition in separating mechanism 6, and be positioned at top that carrier chain send and also be provided with adjustable spring and press straw 17; Sorting mechanism 10 is made up of piano-wire screen 11, broad width conveying belt 12, blower fan 14 and hopper 13.Wherein piano-wire screen 11 be positioned at separating mechanism 6 below, and broad width conveying belt 12 is positioned at 50～80mm place, piano-wire screen 11 belows.The width of the air outlet of blower fan 14 is consistent with the width of conveyer belt 12, and the air outlet of blower fan 14 is between broad width conveying belt 12 and hopper 13; Feed mechanism 18 is made up of screw spreader that is positioned at hopper 13 and the centrifugal Material sucking machine 15 that is positioned at hopper 13 exits; Connecting elevating mechanism 8 is made up of sleeve that has internal thread on the frame 17 and the screw rod 8 that is fixed on the tractor.Regulate by screw rod and complete machine to be risen or fall; Power input mechanism 16 is to import the power of tractor into this miniature rice-wheat combine harvester by belt pulley 19.Frame 1 not only links into an integrated entity each several part, but also achieves a butt joint by it and tractor, and is connected with tractor chassis by strut and reaches reinforcing.
When this miniature rice-wheat combining removed machine work, the rice wheat head bar that will gather in by seedling regulating wheel was swung to machine here earlier, by the reciprocating type cutter of cutting of cutting cutter the rice wheat is cut off again.So the straw of band fringe just is poured on the carrier chain, and will the band straw of fringe directly delivers in an orderly manner to take off in the material mechanism by it and anti-clogging ratchet and go threshing.The straw that wherein sloughs the rice wheat is thrown to outside, machine right side and is fallen within on the ground by the straw mouth that falls, not by the wheel spreading; And rice wheat of taking off and thin slag are fallen behind the steel wire sieve aperture together and are sent to the hopper top on the broad width conveying belt, and thin slag is removed in the wind that blows out of the blower fan under conveyer belt again, and clean rice wheat is just dropped into hopper.The import department of centrifugal Material sucking machine delivered to the rice wheat by screw spreader in the hopper.By centrifugal Material sucking machine rice wheat inspiration carrier pipe is delivered in the storage bag at last.
The present invention has following advantage compared to existing technology: this machine compact conformation is simple, volume is little, in light weight, easy to manufacture, with low cost; Simultaneously it is low in energy consumption, reliable operation, easy and simple to handle, net harvesting rate is high, mobility strong, can adapt to the rice wheat combining of the little field of different physical features piece.
