Description

Combine

The utility model belongs to a kind of agricultural machinery, is particularly useful for the wheat and rice combine harvester with the assembly of separate unit low-power four-wheel tractor.

Done detailed description to commenting in column " spring of the baby combine " literary composition the third phase in 1991 " agricultural machinery " expert with the present situation of the combine of tractor with small four wheels assembly and prospect.Affirmed the prospect of baby combine in the literary composition, proposed the task of top priority and still give 12-15 horsepower tractor combine.The utility model disclosed just with the combine of low-power tractor 15-20 horsepower assembly.The documents relevant with the utility model is disclosed CN87103115A patent of invention on February 10th, 1988, a kind of low-power combine is disclosed in this application, its feature is that star-wheel is held up the standing grain standing header, the horizontally-arranged swing type banding pattern that combines with vertically-arranged is carried feeding unit, the suction scheme realizes threshing, separation in one spinning roller one of air channel, center to be interrupted, and cleans the compositions such as vertically-arranged axial flow device that are integrated.

Qin Feng-No. 1 combine that Fuping, Shaanxi farm build factory produces, this machine coupling power must not be less than 18 horsepowers, its harvesting part is the same with large-scale combine structure, adopts the cylinder rice pulling wheel and carries screw feeder, and translator unit adopts the box belt of sealing to force to transmit, the shortcoming of this machine is, complex structure, consumption of power is big, and when screw feeder is carried by force, the rice wheat is rolled, and loss is shed in threshing.

Be to disclose a kind of and the baby combine assembly of low-power four-wheel tractor order of the present utility model, can once finish the cutting to crop, operation is distinguished in conveying, threshing, and the straw that purifies, the assorted slivering of grain husk are laid in the field.Behind the harvest operation, this tractor can take off branch with the combining part so that other operation.

The scheme of utility model is achieved in that combine is a power with the tractor with small four wheels of 15-20 horsepower, and assembly is with harvesting, the several operation parts of transmission threshing and cleaning.The harvesting operation is adopted and is held up standing grain wheel standing header for a short time, and translator unit is the upright load mode of the open delivery chute vertically-arranged belt composition of a U type, and rotating cylinder on the horizontal axial flow is adopted in the threshing and cleaning operation, and rotating blading is cleaned structure.For a short time hold up standing grain wheel standing header to be articulated on the front bumper of tractor, simultaneously with tractor hydraulic descending operation handle or the liftoff distance of the manual operation handle control ceding of Taiwan.The threshing and cleaning part is drawn on the frame by the back extension that frame fixedly is suspended on tractor, the front end of transport portion is fixedly supported on the knife rest of cutting bed, the rear end is fixedly supported on the frame of threshing and cleaning part, and delivery chute and vertically-arranged cingulum can carry cutting part the crop that come to continue the upright detachment machine porch that is transported to.And the disengaging through breaking away from cylinder makes and breaks away from thing and fall into through sieve plate and clean the effect that is in rotary fan and make outside the assorted machine that flies out of grain husk, and the seed after choosing is clear is through the outlet pack, and crop footpath bar is extracted outside the machine by the uprooting weed wheel at last in the rotation lower edge axially-movable of cylinder rasp bar.This combine is compared with existing combine, has vertical cutting.The simple structure that opening is uprightly transported, horizontally-arranged axial flow takes off branch, flexible operation, the lodging thing also there is certain adaptability, solve 15 horsepowers of problems that the drive combine is short of power, be adapted to the present situation that tractor with small four wheels owning amount big and small-sized towed combine in present rural area lacks.

Below in conjunction with the embodiment accompanying drawing this combine is described in further detail.

Referring to accompanying drawing, the standing header cutting machine is drawn on the front bumper that frame 2 is suspended on tractor by extension, by nearside divider, star wheel lifter 1 stage clip 9 cutters 25, front baffle board 24, about carry cingulum 23 and up and down belt pulley 13 form.Transport portion is seen Fig. 3; Fig. 4 and Fig. 2; transport portion is the open delivery chute 4 of a U-shaped; the outer wall front end of delivery chute has the rebound 10 of the certain radian of being bent into; it is connected with stage clip 9 transition of cutting part; the inwall front end also has the stage clip transition to be connected with front baffle board; so that carrying cingulum about making sends into crop in the delivery chute; the other end of delivery chute is an arc 26; be connected with the shell of threshing cylinder; after being fixed with on the outer wall of delivery chute, send belt pulley 12; 19; 17; 16; wherein; 12; 19 is coaxial powered pulley; 16; 17 is driven pulley, and 15 for holding up belt wheel in the centre, can enter threshing cylinder smoothly in order to make crop; here with driven pulley off-centre; make upper conveyor belt be longer than down conveyer belt,, make the spiral blade 20 of threshing cylinder and pull out tooth 22 crop is brought in the thresher so that crop turns forward during to feeding mouth naturally.Compare with general disengaging cylinder, the cylinder rotation mode of the embodiment of the invention is last rotating, so that crop can feed threshing rapidly, its structure such as Fig. 5, shown in Figure 6, threshing cylinder has only 3 rasp bars 21, and drum central axis does not have rasp bar near an end of feeding mouth, and what 3 spiral blades 20 and some helical arrangement were arranged on the cylinder axis pulls out tooth 22.

The transmission of power circuit is referring to Fig. 7, by the body headstock power is exported by two-way, the first is imported gear-box by gearbox through power take-off, after break-in, drive cutter through the bent axle linkage on the one hand, give preceding conveyer belt and side conveyer belt by belt pulley with transmission of power on the other hand.Another power branch road is to drive threshing cylinder 7, electric fan 6, grass-removing wheel 8 by belt and intermediate transport axle.

The workflow of combine of the present invention is seen figure; be divided into crop to be cut and cutting two parts by nearside divider; under the inertia that advances of star wheel lifter and tractor; with the close cutting bed of crop; after the cutting of cutter; by stage clip 9 and star wheel lifter with crop near on the front apron 24 and by preceding conveyer belt crop uprightly being carried to the right; the crop approaching side is to delivery chute under the escorting of the drive of belt teeth and stage clip 9; and by cingulum 14 with the upright open thresher feeding mouth that delivers into backward of crop; near feeding mouth; because up and down eccentric lodge forward naturally spiral blade on the threshing cylinder and the tooth that pulls out of helical arrangement of crop that make of belt conveyor wheel brought crop into threshing cylinder rapidly; cylinder drives crop high speed spiral shell to be changeed; break away from; emersion object is centrifugal to be left cylinder and falls into choosing through sieve plate and clean the street, and with grain husk outside the assorted fan-out machine, the seed of cleaning falls into the Ji Liangkou pack through fan 6; rasp bar on the cylinder makes straw move along axial flow direction, at last by outside the grass-removing wheel discharge machine.

This combine adopts vertical cutting, and crop is not lost in vertical conveying, and nothing machinery is thrown and loose, and is simple in structure, and easy accessibility is saved power, is present desirable baby combine.
