The utility model content
The purpose of this utility model is, a kind of supporting combine harvester of 12-15 horsepower tractor with small four wheels that is is provided, make it have operations such as one-stop operation is finished cutting, conveying, threshing, separates, cleaned, pack, reduce the results total losses, improve the operation class, alleviate hand labor intensity, fall end complete machine weight, reduce material consumption, reach low damage, efficient one-machine-multi-function.
Small-sized combine harvester described in the utility model comprises the ceding of Taiwan, inclination feed chamber, threshing cylinder, dressing mechanism.The flat the place ahead that places tractor of described ceding of Taiwan floating ground, its upper end hangs over the top of inclination feed chamber housing inlet, the lower housing portion of lower end and inclination feed chamber is fastening, is provided with telescopic oil cylinder in inclination feed chamber lower end, and this telescopic oil cylinder is connected with the ceding of Taiwan with compression spring by support; Described inclination feed chamber has housing, feeding chain harrow, sprocket wheel; Described threshing cylinder has first cylinder and second tin roller, and two cylinders are separately positioned in separately the drum chamber abreast, and two drum chamber interconnect in unidirectional end; Described dressing mechanism has vibration shaker screen, suction fan, and the vibration shaker screen is positioned at the separating mechanism below, and strand is connected on the frame, and air-breathing phoenix machine 7 is positioned at the top of vibration shaker screen.
The advantage of small-sized combine harvester described in the utility model:
1, adopted double threshing cylinder, the threshing length of its cylinder can reach 2 meters, has increased the ability that purifies of this machine and the adaptive capacity of various cereal, has increased feed quantity, has reduced cereal entrainment loss and threshing loss, compact conformation, and production cost reduces;
2, because adopt floating header, flexible cutting knife has profiling preferably, makes cutting height remain on 3-5cm, has significantly reduced to lose the angle loss, increases ceding of Taiwan width, has improved economic benefit;
3, because adopt drawing fan to make structural volume little, air quantity is big, the clean rate height, thus make the complete machine structure size more reasonable;
4, because employing is twin-engined, former little four-wheel 12-15 horsepower engine is adopted in walking, and the 15-18 horsepower engine is adopted in threshing, has increased the dynamic property of machine and the stepless shift function of walking;
5, the overall arrangement of this machine because adopt the biasing ceding of Taiwan, makes the configuration of twin shaft stream roller more reasonable, has both increased and has cut good fortune, has improved operating efficiency, reaches compact conformation again;
6, bridge is positioned at ceding of Taiwan rear, has widened the visual field, is convenient to handle.
Most preferred embodiment below in conjunction with description of drawings miniature combine described in the utility model.
Description of drawings
Fig. 1 is the front view of miniature combine described in the utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, small-sized combine harvester described in the utility model is to be the supporting combine harvester of 12-15 horsepower tractor with small four wheels.Each parts of complete machine are installed on the frame, and frame is connected by bolt with tractor with small four wheels.
Combined harvester described in the utility model comprises the ceding of Taiwan 1, inclination feed chamber 3, U type threshing axial-flow type drum 12, dressing mechanism and unloading mechanism and actuating unit.
The flat the place ahead that places tractor of the described ceding of Taiwan 1 floating ground, has ceding of Taiwan body, cam-action reel, athwartships propeller, flexible cutting knife and running part, its upper end hang over the inlet top of inclination feed chamber 3 housings, and the lower end is fastening with the lower housing portion of bolt and nut and inclination feed chamber 3.Lower end at inclination feed chamber 3 is provided with telescopic oil cylinder, and the lifting of the ceding of Taiwan realizes by this telescopic oil cylinder.Telescopic oil cylinder is connected with the ceding of Taiwan with compression spring 4 by telescope support, and during ceding of Taiwan work, floating header and flexible cutting knife 2 are worked simultaneously, cutting height is remained on below the 3-5cm, and ceding of Taiwan percent of loss is below 5%, and, supreme native phenomenon guarantees that threshing do not have the mud paint face.
Described inclination feed chamber 3 is made up of housing, feeding chain harrow, sprocket wheel etc., and the crop that cuts down enters inclination feed chamber 3, sends into U type threshing cylinder 12 by the feeding chain harrow again.
Described U type threshing cylinder 12 is made up of spike-tooth rasp bar, punching notch board and guide plate etc., crop by first cylinder to second tin roller through the threshing of U type route.Drum length is 2 meters, and crop will be rotated threshing and separate through 8-10 week, and clever shell, grain enter dressing mechanism 5, and stalk is discharged outside the body.So-called U type threshing cylinder is meant that first cylinder and second tin roller are separately positioned in separately the drum chamber abreast, two drum chamber interconnect in unidirectional end, entered by the end inlet of the cane of threshing from first cylinder, behind first drum threshing, export by the other end, enter second threshing cylinder again, thereby cane becomes the walking of U circuit.
Described dressing mechanism has vibration shaker screen 5, suction fan 7 etc.Vibration shaker screen 5 is positioned at the separating mechanism below, and strand is connected on the frame.Suction fan is positioned at vibration shaker screen top, picks up impurity and clever shell when cleaning above it, and impurity and clever shell enter volute of blower by the inlet scoop, outside induced-draught fan discharge machine.
Described unloading mechanism is made up of tanker 9 and bucket elevator 8.Compact integral structure, reliable operation.
The power of miniature combine described in the utility model is 15-18 horsepower engine 10.
The course of work, crop is cut off by cutter 2, enters central auger, enters first axial-flow type drum 12 by 3 outlets of inclination feed chamber again,, is thrown outside the grass wheel discharge machine through the stalk of threshing to second axial-flow type drum through threshing.Chaff skin, grain and minority stalk enter the vibration shaker screen of cleaning cylinder 5 by notch board, separate with beans at this chaff skin, the chaff skin is sucked outside the spiral case discharge machine by suction fan 7, the grain of cleaning enters unloading elevator 8, deliver to tanker 9 by unloading person's gunnysack of packing into, assortedly surplusly deliver to cylinder 12 by bucket elevator 8 and take off again.The grain clean rate can reach 99%, and percentage of damage is below 3%, and total loss rate is lower than 6%.
Bridge 13 designs are important steps of this machine, and bridge moves to ceding of Taiwan top.Twin-engined accelerator rods, clutch pedal, brake etc. all adopt flexible pipe to drive, and increase a 200W dc motor, increase instrument such as engine oil pressure, indicating fault instrument.
This machine integral layout is reasonable, and its weight is evenly distributed on the tractor, and tractor need not to change significantly, and former car frame is connected with the grain header frame.Bridge moves to ceding of Taiwan top.This machine can not only gather in the field, on the field threshing.During use, only needed to be assembled on the tractor in 3-4 hour, not the time spent, can unload recovery tractor original function with 1-2 hour.
