Described cutting assembly is connected with driving shaft by trace, and is installed on the supporting plate by bolt together with the feeler mechanism support.
Described ceding of Taiwan upper end hangs over the inlet top of gap bridge housing, and the lower end is fastening with bolt and nut and gap bridge lower housing portion; Be provided with telescopic oil cylinder in the lower end of passing a bridge, should be installed on the frame by cylinder.
Combine described in the utility model, be particularly suitable for being used for gathering in the crops Soybean and Other Crops, 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.
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 the arrisdefect loss, and its ceding of Taiwan loss is lower than 2%;
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 swath, 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 a ceding of Taiwan schematic diagram;
Fig. 3 is the feeler mechanism schematic diagram;
Fig. 4 is the structure chart of sheller unit.
Embodiment
Referring to Fig. 1, combine harvester described in the utility model comprises the ceding of Taiwan 1, gap bridge 2, sheller unit 3, dressing mechanism 4, the described ceding of Taiwan 1 floating ground, the flat rear that is arranged on tractor with putting.This machine 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.
Referring to Fig. 2, the described ceding of Taiwan 1 comprises cutter sweep, and this device has cutting driving mechanism 5, cutting assembly 6, feeler mechanism support 7 and supporting plate 8.Described cutting driving mechanism 5 comprises that cutter driving shaft 9, these driving shaft 9 one ends are installed in the pendulum ring fork of fixedlying connected with ceding of Taiwan body, and the other end is installed on the support 7 by ball bearing 15.It has two effects, and the one, drive cutter, back and forth rotation reaches the purpose of cutting crop; The 2nd, make the four-bar mechanism upper branch arm.
Described cutting assembly 6 is connected with driving shaft 9 by trace 21, and is installed on the supporting plate 8 by bolt with feeler mechanism support 7.Lower branch arm 10 front ends are connected with supporting plate 8 by bracket pins 11, and the rear end is connected with ceding of Taiwan body by lower branch arm pin 12.Form a quadric chain like this.See Fig. 3, the P point is fixedlyed connected with ceding of Taiwan body with the B point, and O point and C point can float.During cutting, supporting plate 8 pastes ground, can rise and fall with the fluctuating on ground, and it is low therefore to cut stubble, and it highly remains on below the 3-5cm, and the cutting loss is also low.
The ceding of Taiwan 1 upper end hangs over the inlet top of 2 housings of passing a bridge, and the lower end is fastening with 2 lower housing portion of passing a bridge with bolt and nut.Lower end at gap bridge 2 is provided with telescopic oil cylinder, should be installed on the frame by cylinder, and the ascending, descending of the ceding of Taiwan realizes by this telescopic oil cylinder.
Referring to Fig. 4, described sheller unit 3 comprises two horizontally sets (perpendicular to the direction of machine travel), first threshing cylinder 16 that is parallel to each other, second threshing cylinder 17 and first threshing chamber and second threshing chamber that at one end are communicated with, above-mentioned two threshing cylinders are installed, is provided with delivery wheel 18 between two threshing chambers.Like this, after the crop cane enters sheller unit, the similar U molded lines of the route of being walked, its track route increases, and threshing performance is greatly improved.
Described threshing cylinder is made up of spike-tooth rasp bar, punching notch board and guide plate etc., owing to have delivery wheel 18 between two cylinders, crop is delivered to the second tin roller threshing by delivery wheel 18 behind first drum threshing, can not produce clogging.
Described dressing mechanism has vibratory sieve, suction fan etc.Vibratory sieve is positioned at the sheller unit below, and strand is connected on the frame.Suction fan is positioned at the vibratory sieve 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.
Because the ceding of Taiwan of combined harvester described in the utility model is mounted in the rear of tractor, in the work, the tractor backward, crop is cut off by cutter, send into the conveying chain harrow of gap bridge by walking crosswise conveyer, enter first axial-flow type drum 16, to second threshing cylinder, thrown outside the grass wheel discharge machine after the process threshing through the stalk of threshing.Chaff skin, grain and minority stalk enter vibratory sieve by notch board, separate with beans at this chaff skin, the chaff skin is sucked outside the spiral case discharge machine by suction fan, the grain of cleaning enters the unloading elevator, by unloading person's gunnysack of packing into, assorted surplusly taken off again by rethresher sent vibratory sieve back to by spinner then and cleaned again.
