Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 8, a kind of small harvester, comprises group standing grain device 1 be arranged at foremost, dials standing grain device 1 rear and is provided with shear 2, dials standing grain device 1 rear lower portion and is also connected with transfer system 3; Described transfer system 3 rear end is provided with threshing system 4 and aidr bells blast system 6, and threshing system 4 is also provided with elevator system 5; Running gear 7 is also provided with bottom described small harvester.
Described group of standing grain device 1 comprises grain lifter 11 and a pair symmetrically arranged dialing-grain unit 12.
Be provided with sprocket wheel 125 bottom described dialing-grain unit 12, in the middle of sprocket wheel, rice-pulling shaft 126 be installed, rice-pulling shaft 126 is provided with successively two and dials standing grain dish 123; Described two sides of dialling near rice-pulling shaft 126 on standing grain dishes 123 are provided with push rod 124, two dial standing grain dish 123 near outer place also each uniform intervals be provided with a circle rice-pulling tooth 122, the outer of described group of standing grain dish 123 is provided with and dials standing grain dish guard shield 127.
Rice-pulling tooth 122 on described each group of standing grain dish 123 is four.
Described running gear 7 comprises horizontally disposed transmission shaft 79, is set with bevel gear I 761 and bevel gear II 762 in the middle part of transmission shaft 79; Between bevel gear I 761 and bevel gear II 762, tip position vertically connects power shaft 77; The outside of bevel gear I 761 and bevel gear II 762 is respectively provided with two bearings 711, is connected between described two bearings 711 by sleeve 712; Described transmission shaft 79 two ends are connected two horizontally disposed output shafts respectively by clutch I 72 with clutch II 710; Clutch I 72 and be all connected with spring 78 between clutch II 710 and bearing 711; Clutch I 72 and clutch II 710 is also respectively arranged with left and right engaging and disengaging gear 73, and the top of this left and right engaging and disengaging gear 73 is all set on left and right clutch shaft 74; Also be provided with the fork 713 that falls back between described bevel gear I 761 and bevel gear II 762, described in fork 713 one end of falling back connect and to fall back fork axle 714.
Described transfer system 3 comprises transmission chain 31, and described transmission chain 31 side is provided with press strip 32.
When using this small harvester to gather in, the grain lifter of grain header front end can, by seedlings of cereal crops righting to be gathered in, facilitate shear to shear seedlings of cereal crops root.The seedlings of cereal crops cut off enter in dialing-grain unit, and the sprocket wheel on dialing-grain unit is driven by rice-pulling shaft and dials standing grain dish synchronous axial system, dials the rice-pulling tooth also run-in synchronism thereupon on standing grain dish.When rice-pulling tooth runs to push rod position, rice-pulling tooth is backed down by push rod, and the tip of rice-pulling tooth front end is stretched out, and plays the effect of dialling standing grain.Rice-pulling tooth can move along the cambered surface of push rod always, and after leaving push rod cambered surface, rice-pulling tooth can be regained under the catch effect on group standing grain dish guard shield, makes it no longer protruding, and what complete epicycle dials standing grain task.Along with the continuous running of sprocket wheel, the rice-pulling tooth dialled on standing grain dish can circulate in turn and stretch out and regain, thus reaches group standing grain object, the seedlings of cereal crops of harvesting can be sent in the transfer system of rear end endlessly.
After the seedlings of cereal crops are involved in by dialing-grain unit, can be sent in the threshing system of rear end carry out the operation such as threshing and selection by winnowing by transmission chain, the press strip on transmission chain is then guaranteed can not be scattered in seedlings of cereal crops transport process.And the elevator system on threshing system can improve threshing efficiency further.
In the grain header course of work, user can control direction and the circuit of its motion by running gear.When the power shaft of running gear rotates, two bevel gears are driven to do rightabout motion.Now, operator just can come controlled motion direction by manipulating the declutch shift shaft that falls back.
When the declutch shift shaft that falls back is positioned over centre position, the shift fork that falls back also mediates, and all do not contact with bevel gear II with the bevel gear I of both sides, now running gear is in neutral gear position, and output shaft does not rotate, and grain header cannot move.
When the declutch shift shaft that falls back is stirred left, the shift fork that falls back then moves right, and combines with bevel gear I, and now, power transmission shaft and fall back shift fork along with bevel gear I synchronous axial system, running gear is in setback state.Now, operator can also carry out Compress Spring by left and right engaging and disengaging gear, thus clutch I is separated, and then can realize left and right turn function when retreating.
In like manner, when the declutch shift shaft that falls back is stirred to the right, the shift fork that falls back is moved to the left, and combines with bevel gear II, and now, running gear is in the state of travelling forward.Now, operator can carry out solenoidoperated cluthes II by left and right engaging and disengaging gear equally thus realize left and right turn function when advancing.
The utility model principle is simple, easy to use, and flexibility is strong, and operating efficiency is high, and design and manufacture cost is cheap, has very strong practical value.
