Description

Full suspension combine harvester

The utility model relates to agricultural harvesting machinery, particularly a kind of integral combine that is configured on the tractor.

The integral combine that is configured on the tractor is existing multiple, and being used for of having produces.But because the wheat per mu yield is more and more higher, and tractor, particularly tractor with small four wheels power is limited, causes the conveying burden of combine and threshing and cleaning load too big, and operation quality descends, even stops up, can not normal operation.Alleviate the load of combine, make the supporting combining function of small tractor satisfy agriculture requirement, normal operation is a problem demanding prompt solution.

The purpose of this utility model will provide a kind of exactly can reduce live load, satisfies field harvest operation requirement, the integral combine of reliable operation.

For finishing above goal of the invention, designed a kind of ceding of Taiwan by the band straw shift wheel, vertically delivery chute and threshing cleaning unit are formed, be configured in the integral combine on the tractor, also has row's cutter below the cutter of harvester header, following row's cutter postposition, this double-deck cutter can divide two sections to cut off upright crop, epimere band fringe straw is sent into cylinder through the ceding of Taiwan and vertical delivery chute, hypomere does not have the fringe straw and stays the also field of ceding territory upward, thus the burden that has alleviated conveying mechanism greatly and rolled a cleaning plant; The cylinder of its threshing cleaning unit is an axial-flow type drum, and the cylinder straw outlet has the grass-removing wheel with little notch board, and this structure can prolong threshing course, improves threshing performance; Its cleaning plant is made up of reciprocating screen and fan, and the reciprocating screen leading portion is the breach sieve, and back segment is the shell sieve, and cleannes can meet the demands basically, but percent of loss is low, has avoided the waste of grain; Be provided with the collection tanker of unloading base plate below its threshing cleaning unit, but the big edge of a field unloading of capacity pack at random without the special messenger, practicality is fine.

In order further to improve functional reliability, the embodiment of the utility model integral combine is: straw shift wheel adopts the cam-action reel that the effect of falling the standing grain of holding up is arranged, the horizontal ceding of Taiwan of the strong band screw feeder of applicability is adopted in the ceding of Taiwan, vertically delivery chute adopts the following carrier chain of taking off of the strong band grilled teeth of conveying capacity, the ceding of Taiwan and straw shift wheel are directly driven by the flywheel on the tractor, threshing cleaning unit and vertical delivery chute are by outputting power of tractor gear case, via the drive driving of a band manually-operated clutch.Segmentation control like this, the benefit that drives are: can drive vertical delivery chute and threshing cleaning unit earlier during the beginning operation, make it reach working speed before straw of being with fringe enters, guarantee operation quality; Can make the ceding of Taiwan stop harvesting earlier when stopping operation again, quit work again after allowing vertical delivery chute and threshing cleaning unit that the band fringe straw of having cut off is handled, avoid shutting down obstruction.The actual use through the field, the utility model combine can the full swath work of III shelves speed in the plot of 800 jin of per mu yields, and total loss rate is lower than 3 percent, and every index all reaches job requirements.

Below in conjunction with drawings and Examples the utility model is described.

Fig. 1 is the utility model integral combine schematic diagram.

As shown in Figure 1, the horizontal ceding of Taiwan 34 is made up of upper strata cutter 3, lower floor's cutter 2, the sliding palm 1 of profiling, horizontal screw feeder 25, the horizontal ceding of Taiwan 34 front upper places are eccentric type straw shift wheels 6, straw shift wheel 6 and upper strata cutter 3, lower floor's cutter 2 and horizontal screw feeder 25 are driven through drive pulley and travelling gear 5 by tractor flywheel 10.Be the following formula carrier chain 12 of taking off of band grilled teeth 11 in the delivery chute 13 vertically, the axial-flow type drum 15 of band notch board 16 is arranged in the threshing cleaning unit 14, the grass-removing wheel 17 with little notch board 18 is arranged in the straw outlet 19 of cylinder 15.Cleaning plant is made up of reciprocating screen 24 and fan 25, reciprocating screen 24 leading portions are breach sieves 21, back segment is a shell sieve 22, fan 25 is with wheat bran, the assorted surplus impurity discharging port 23 that blows out, clean seed falls into collection tanker 27 through collection grain mouth 26, and collection tanker 27 has unloading base plate 29 and unloading spanner 28, vertically delivery chute 13 and cylinder 15, grass-removing wheel 17, reciprocating screen 24 and fan 25 are driven via the drive 31 with the clutch 32 of manual handle 34 by one 22 outputting power of tractor gear case.The elevating lever 30 of tractor makes the ceding of Taiwan along 9 liftings of arc portal frame by steel wire rope 8.

Claims (2)
