Description

Combine harvester for rice and wheat

The utility model discloses a kind of rice/wheat combine.

Most of area in China rural area, the harvesting of wheat and threshing remain manual and cut off straw, are transported to then on the thrashing floor for wheat, press to roll over small-sized electric thresher or small tractor (even also useful livestock) dragging roller and realize threshing; In the paddy rice producing region, still be to cut off straw by hand, put together threshing on Electric rice thresher or foot-operated rice thresher again, though Japanese combine large-scale combines such as (combine) just occurred resembling in early seventies, needed large-scale farm tractor traction.It is bulky, and complex structure involves great expense.Such large-scale combine only is only applicable to the operation under the large tracts of land condition of flat area, does not adapt to operation on the splats in most areas, rural area, and is particularly incompatible in the operation of the hilly country in paddy rice producing region.Someone had once successfully designed the baby combine (as Chinese patent 85108023, Russian Patent 1020046 and 1037866) of agricultural miniature tractor-drawn, it is relatively simple for structure, cost is also not too high, but also there is following deficiency in these small-sized rice/wheat combines: (1) grain lifter shoots down in the field part cereal-granules, dry when hot this kind phenomenon even more serious: (2) must cut off straw, be sent to the rear by roller, so just structurally go back more complicated, power consumption is also big; (3) the cleaning in the operation of grain tassel part threshing object, do not solve the problem that cavings flies upward well everywhere, influence operating personnel's operate as normal.

The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and the small-sized rice/wheat combine of a kind of suitable China present tillage condition in rural area is provided.

The utility model mainly is made up of crochet hook formula dialing-grain unit, chasing tool, clamping cone, horizontal hopper, drag-flight conveyer and dressing mechanism etc.It is characterized in that: the cereal plant is under the density state of self-sow, dialled in the chasing tool queuing successively by crochet hook formula dialing-grain unit, by the clamping force (the also frictional force of available its form) that clamps cone the cereal straw is moved downward orderlyly again, the grain tassel part particle is wiped off by chasing tool, and flow into horizontal hopper along the chasing tool slope, this structure can not cause cereal-granules to shoot down splashing in the field, cause waste; Because this machine is an early threshing, so can gather in straw according to actual needs, also can not gather in straw, this just has very big freedom for peasant household.If do not need stalk cutting rod, can save the labour on the one hand, straw is stayed the field on the other hand, deep ploughing is pressed in the soil straw as organic manure, and after threshing object was cleaned, cavings was unrestrained along ground along a bend pipe, and can not fly upward over the sky, influence operating personnel's operate as normal.

Accompanying drawing 1 is an operation principle schematic diagram of the present utility model (side-looking).

Wherein: 1 wheat head, 2 crochet hook formula dialing-grain unit assemblies, 3 chasing tool assemblies 4 clamp cone assembly 5 parallelogram cutter copying devices 6 horizontal hopper 7 horizontal spiral propeller assemblies 8 cutter piston shoes 9 cutteves 10 drag-flight conveyer assemblies 11 blower fan assemblies 12 cyclone type dressing mechanism assemblies

Be explained in detail with reference to 1 pair of the utility model of accompanying drawing.

The cereal plant is under the density state of self-sow, colluded successively into chasing tool (3) by number row's crochet hook formula dialing-grain units (2) up and down and to line up, by the clamping force (the also frictional force of available other form) that clamps cone (4) the cereal straw is moved downward orderlyly again, the fringe portion (1) of cereal is just wiped off by chasing tool (3).At this moment, the grain tassel part threshing object flows into horizontal hopper (6) along the slope of chasing tool (3).Horizontal spiral propeller (7) in placing horizontal hopper (6) is delivered to the aggregate bin on right side earlier, delivers to cyclone type dressing mechanism (12) through drag-flight conveyer (10) then and cleans.The chaff of cereal is unrestrained along ground through bend pipe, and the particle of cereal is stayed the mouth of putting out cereal of in the silo, regularly or irregularly opening silo, and the particle of cereal is adorned gunnysack get final product.

The hinge that connects and composes parallelogram of cutter piston shoes (8) and frame, i.e. parallelogram cutter copying device (5), cutter piston shoes (8) slide before tightly being affixed on ground under action of gravity, adjust its height automatically.No matter therefore how landform changes, always make scraper remain level.

In cyclone type dressing mechanism (12), the wind pipe of fan blower becomes tangentially to be connected with blanking (threshing object of grain tassel part) pipeline, and the mixture of wind cereal-granules and chaff thereof enters silo and forms vorticity.Because the difference of proportion is sunken to the silo bottom under the cereal-granules, the come-ups such as fragment of cavings and leaf are discharged silo through bend pipe.

Accompanying drawing 2 is transmission of power schematic diagrames of the present utility model (overlooking).

Wherein: 13 cutter belt pulleys, 14 horizontal spiral propeller belt pulleys, 15 tumbler gears 16 clamp cone travelling gear 17 nearside dividers 18 bevel gears 4 and clamp cone 19 chasing tools 7 horizontal spiral propeller assemblies 10 drag-flight conveyer assemblies 20 cutter connecting rods 21 cutter levers 2 crochet hook formula dialing-grain units 9 cutter assemblies 22 crochet hook formula dialing-grain unit drive assemblies 23 power distributing shafts 24 tractor flywheel belt pulleys 11 blower fan assemblies 25 gear box of tractor belt pulleys

The utility model will be further described with reference to accompanying drawing 2

On agricultural miniature tractor flywheel (24), adorn one six groove belt pulley.With three V belts power is delivered on the power distributing shaft (23) from flywheel (24).

Crochet hook formula dialing-grain unit drive assembly (22) to crochet hook formula dialing-grain unit (2), makes its action to the transmission of power on the power distributing shaft (23):

To cutter belt pulley (13), latter's tumbler gear (15) links together through clutch and cutter lever (21) the transmission of power on the power distributing shaft (23), clutches engaged, and cutter is just carried out " instruction " of cutting off the cereal straw, otherwise opposite;

Another function of tumbler gear (15) be the transmission of power on the power distributing shaft (23) to horizontal spiral propeller belt pulley (14), it is advanced to cereal-granules in the horizontal hopper and chaff thereof in the aggregate bin of right-hand member.

By bevel gear (18) with the transmission of power on the power distributing shaft (23) to clamping cone travelling gear (16), the latter makes and clamps cone and enter duty.Since clamp cone (4) be in gyrate among, collude into the cereal straw of chasing tool (19) by crochet hook dialing-grain unit (2) and to be left behind fast, grain tassel part (1) is wiped off by chasing tool (19), has realized not cutting the purpose of design that the cereal straw just can threshing.

Because the rotation direction of any two adjacent clamping cones (4) is opposite, for preventing that the cereal straw from being dialled, so nearside divider (17) is arranged to guarantee to make the position of every strain cereal straw branch to needs in the place ahead design that clamps cone (4).

Drag-flight conveyer (10) obtains power from the right-hand member of horizontal spiral propeller (7), the grain threshing thing of aggregate bin is transported to dressing mechanism cleans.

The power of blower fan is from the gearbox pulley (25) of tractor, and for satisfying the blower fan requirements of one's work, the diameter of blower fan belt pulley must be less than gear box of tractor belt pulley (25) diameter, its optimum ratio 1:1.1-2.0.Otherwise can cause the failure of cleaning.

In sum, the utility model has overcome the deficiency of prior art, has realized not cutting the just purpose of design of energy threshing and cleaning of cereal straw. The advantages such as these facility have simple in structure, save power, and the cereal-granules loss is few during the low and results of cost can support the use with various farm tractors. This machine is suitable for the grain harvest under the present tillage condition in the vast rural area of China.
