Embodiment
Below with reference to the accompanying drawings and embodiment further illustrate the utility model.
Fig. 1 is the utility model general arrangement structure, a stock power transmission shaft 1, and one end connects driven fuel dynamic engine 2, other end clutch disk cutting blade 3, Bo He mechanism 4 and nearside divider 5.Described stock power transmission shaft 1 is the oval bars of two ends with connection spline, is fixed in a hollow bushing 12, power transmission shaft freely can be rotated with axle center in hollow bushing 12 by bearing 11 as support.The position suitable in the outside of hollow bushing 12 is installed for takeing on the braces 13 of carrying on the arm and the handrail 14 controlling grain header, grain header can be made can be carried on the arm the back of the body and carry piggyback and utilize handrail to manipulate grain header.
As shown in Figure 1 and Figure 2, by a centrifugal clutch 6 between stock power transmission shaft 1 and driven fuel dynamic engine 2, make the two be connected, the output shaft 21 of driven fuel dynamic engine 2 is affixed with the rotating centrifugal block 61 of centrifugal clutch, and power transmission shaft 1 is connected with the terminal pad 62 of centrifugal clutch by spline form.When driven fuel dynamic engine operates, when the output shaft rotating speed of driven fuel dynamic engine reaches certain speed, because the effect centrifugal-block of centrifugal force contacts with terminal pad, and terminal pad is driven to rotate, and by the transmission of power of driven fuel dynamic engine to power transmission shaft, then be delivered to other moving components by power transmission shaft.Like this by regulating the throttle of engine, change engine speed realizes the clutch between engine and decelerator.The throttle of greater engine when needing grain header to work, improves engine speed and clutch can be made to contact, harvester cutter work.When harvester cutter does not need running, close the throttle of puffer, reducing engine speed can make clutch separation, and harvester cutter shuts down.
As shown in Figure 1, Figure 3, the decelerator 7 that one end that described stock power transmission shaft 1 is connected with mechanical shoulder cut-off knife sheet 3, Bo He mechanism 4 and nearside divider 5 consists of one group of bevel gear is connected, the power shaft 71 of the decelerator 7 of described bevel gear composition is connected with stock power transmission shaft 1, the output shaft 72 of the decelerator 7 of described bevel gear composition exports with upper and lower two ends, lower end exports connecting portion 73 and is connected with cutting blade 3, and upper end exports connecting portion 74 and connects Bo He mechanism 4.Two gear shaft shapes of the decelerator 7 of described bevel gear composition are at a certain angle, make coupled power transmission shaft 1 and bevel gear composition decelerator 7 output shaft 72 also shape form an angle, during use grain header, when shoulder carries hand held harvester on the arm, cutting blade 3 is parallel to the ground, is beneficial to cutting.
One input and output gear reduction unit 8 is in the same way installed between the upper end connecting portion 74 of bevel gear reducer output shaft 72 and Bo He mechanism 4, the upper end connecting portion 74 of bevel gear reducer output shaft is connected with the input 81 of input and output gear reduction unit 8 in the same way, the rice crop-poking wheel axis 41 of Bo He mechanism 4 is connected with input and output gear reduction unit output 82 in the same way, input and output in the same way gear reduction unit 8 rotating speed of engine 2 is dropped to Bo He mechanism straw shift wheel needed for rotating speed, and transmission direction remains unchanged.
As shown in Figure 1, Figure 4, Figure 5, described Bo He mechanism 4 is made up of a upright axle 41 and interval is fixing thereon multiple straw shift wheel dishes 42, and described rice-pulling shaft 41 is arranged vertically with cutting blade 3; Straw shift wheel dish 42 is flat circular configuration and is radially stretching out many slender rod pieces, form rice-pulling tooth bar 43, described many rice-pulling tooth bars 43 are circumferentially uniformly distributed, and the version of rice-pulling tooth bar is arc-shaped rod, be beneficial to conveying cut off thing put in place time, be conducive to being separated with cutted crop.Rice-pulling shaft 41 is through the core dialling standing grain dish, and multiple groups of standing grain rim axially spaced-apart distributions, the upper, middle and lower cutting off thing is all pushed, and making to cut off thing can be driven by straw shift wheel group, erectly can be transported to rear or the proceeds posterolateral of cutting blade.
As shown in Fig. 1, Fig. 6, described nearside divider 5 enters into cutter scope for importing cut crop, and cuts off thing and can be directed into desired position, and can make when conveying puts in place cut crop in time and straw shift wheel depart from.Described nearside divider 5 forms cutting transfer passage 55 and cuts off thing backward or to the guiding channel 56 of side lay.Nearside divider 5 has the facade of two plane bodies or curved surface body, wherein a facade 51 is positioned at outside the circumference of mechanical shoulder cut-off knife sheet 3, another facade 52 face is positioned at the top of mechanical shoulder cut-off knife sheet 3, and their forward position is all in the front of mechanical shoulder cut-off knife sheet 3, the part of mechanical shoulder cut-off knife sheet between two facades is cutting part 31, and namely the cutting part 31 of cutter is positioned at the centre of nearside divider and dials the vertical shaft of standing grain device and be in outside nearside divider 5.Two fore belows of facade of described nearside divider are given prominence to forward, form two facades that there is wedge angle 53 below.Cut crop can be separated by its wedge angle 53 from root, and the crop that needs are cut off enters into cutting transfer passage 55 and arrives the position of the cutting part 31 of mechanical shoulder cut-off knife sheet 3 and be cut, and does not need the crop of cutting off to be split into outside cut coverage.Two facades 51,52 are formed at the rear of cutting part 31 cuts off thing backward or to the guiding channel 56 of side lay.
Described nearside divider also includes and protects sword frame 9; be positioned at outside the outline of the blade of the non-cutting of mechanical shoulder cut-off knife sheet 3; be made up of with the many rod members 92 that the bar of arc is connected with bevel gear reducer 7 housing the bar 91 of an arc; form the protection to mechanical shoulder cut-off knife sheet 3 blade; and nearside divider 5 and two facades thereof are fixed by protecting sword frame 9 to be connected and fixed with the housing of the decelerator 7 being provided with one group of bevel gear, the non-moving parts such as external hollow sleeve pipe 12 together with stock power transmission shaft 1 is integrally connected.
The facade 52 that described nearside divider 5 the is positioned at mechanical shoulder cut-off knife sheet 3 top position corresponding with Bo He mechanism straw shift wheel 42 has long slot bore 54, and what make the rice-pulling tooth bar 43 of straw shift wheel be stretched out the top of the cutting part entering into wheel cutter by long slot bore 54 dials standing grain region.Be beneficial to dial standing grain.
When gathering in, by takeing on the braces of carrying on the arm and tiltedly to be carried on the arm piggyback by complete machine and both hands handrail controlling operative orientation and the form of complete machine, make the cutter part of grain header front, engine rear, the open front subtend crop to be cut of nearside divider.Start engine, and raising rotating speed of opening the throttle, make power by power transmission shaft 1 and decelerator 7, be delivered to cutting blade, make cutting blade rotary work, and by the decelerator 8 that blade is coaxial, straw shift wheel dish 42 is rotated again, form lower blade constantly circumgyration incision, the rice-pulling tooth bar on top constantly stretches out from the front end of the long slot bore of straw separating plate and to move backward and at the forms of motion of rear end indentation.When operator walks forward, first nearside divider enters the both sides of crop to be cut and is separated by the crop not needing to cut, and guide crop to be cut enter into the cutting zone of cutting blade and be cut, cut crop is stirred backward by rice-pulling tooth bar and moves backward along the guiding channel 56 that nearside divider is formed simultaneously, and cut rear field, products for further process by neat lay to side or back.
