Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model patent is done and to be further described.
As shown in Figure 1, a kind of novel rice transplanter running gear comprises frame, power set, sprocket wheel, chain, sprocket shaft, double-crank mechanism and walking pin etc., and wherein, power set are arranged on the left side, middle part of frame.
Like Fig. 1, Fig. 2 and shown in Figure 3, first sprocket shaft 6 is connected with the crank of first double-crank mechanism 4 and second double-crank mechanism 11 respectively with second sprocket shaft, 7 both sides and drives first double-crank mechanism 4 and the motion of second double-crank mechanism 11; Simultaneously, also be provided with second sprocket wheel 19 and the 5th sprocket wheel 21 on second sprocket shaft 7, wherein, second sprocket wheel 19 is connected with first sprocket wheel 18 on the power set output shaft through first chain 3.
The 3rd sprocket shaft 13 is arranged on the postmedian of frame, and an end of the 3rd sprocket shaft 13 and the 4th sprocket shaft 15 is connected and drives crank with the crank of the 3rd double-crank mechanism 17 makes circular motion; Simultaneously, the 6th sprocket wheel 23 is set also on the 3rd sprocket shaft 17, wherein, the 6th sprocket wheel 23 is connected with the 5th sprocket wheel 21 on second sprocket shaft 7 through the 3rd chain 12.
In double-crank mechanism, first double-crank mechanism 4 and second double-crank mechanism 11 are symmetricly set on the left and right sides of frame 5 about the frame central line, and first double-crank mechanism 4 is parallel and isometric with the crank of second double-crank mechanism 11; The 3rd double-crank mechanism 17 is arranged at central rack, and the crank of itself and first double-crank mechanism 4 is isometric, but angle is 180 degree.
The first walking pin 1 links to each other with the connecting rod of first double-crank mechanism 4 through connecting rod; Equally, the second walking pin 10 links to each other with the connecting rod of second double-crank mechanism 11, and the third line is walked pin 16 and linked to each other with the connecting rod of the 3rd double-crank mechanism 17.
The crank equal in length of all as previously mentioned double-crank mechanisms, length of connecting rod also equate.
For avoiding that the phenomenon that two cranks rotate in opposite direction takes place in the double-crank mechanism; Chain has synchronizing function; Be respectively arranged with first sprocket shaft 6 and the 4th sprocket shaft 15 at frame front and rear portion; Wherein, the 3rd sprocket wheel 8 that is provided with on first sprocket shaft 6 links to each other through the 4th sprocket wheel 20 that is provided with on second chain 9 and second sprocket shaft 7, and the 8th sprocket wheel 24 that is provided with on the 4th sprocket shaft 15 links to each other through the 7th sprocket wheel 22 of setting on the 4th chain 14 and the 3rd sprocket shaft 13; Simultaneously, the crank that first sprocket shaft 6 and second sprocket shaft 7 drive first double-crank mechanism 4 and second double-crank mechanism 11 simultaneously rotates, and the crank that the 4th sprocket shaft 15 and the 3rd sprocket shaft 13 drive the 3rd double-crank mechanism 17 simultaneously rotates.
During operation; The power set output shaft drives 18 rotations of first sprocket wheel; First sprocket wheel 18 drives 7 rotations of second sprocket shaft under first chain 3 and 19 effects of second sprocket wheel, and the 5th sprocket wheel 21 on second sprocket shaft 7 drives 13 rotations of the 3rd sprocket shaft under the effect of the 3rd chain 12; Because of the 5th sprocket wheel 21 is equal with the 6th sprocket wheel 23 numbers of teeth, therefore second sprocket shaft 7 equates with the 3rd sprocket shaft 13 rotating speeds.And first sprocket shaft 6 and the 4th sprocket shaft 15 retrain the crank-motion direction of double-crank mechanism under the effect of second chain 9 and the 4th chain 14.
During operation, first double-crank mechanism 4, second double-crank mechanism 11 drive rotation down at second sprocket shaft 7, and simultaneously, the 3rd double-crank mechanism 17 rotates under the 3rd sprocket shaft 13 drives, and makes the connecting rod of three groups of double-crank mechanisms do translation respectively; The crank of cause first double-crank mechanism 4 and the crank angle of second double-crank mechanism 11 are 0 degree; And crank diameter equates; So; The first walking pin 1 that links to each other with the double-crank connecting rod and the second walking pin 10 are simultaneously to reach or simultaneously as feet, that is, the first walking pin 1 and the second walking pin 10 are fully synchronously.The relative angle of the crank of the crank of first double-crank mechanism 4 and the 3rd double-crank mechanism 17 is 180 degree again, so, walk pin 10 during when the first walking pin 1 and second as feet, the third line is walked pin 16 to reach; Walk pin 10 when moving forward when the first walking pin 1 and second, and the third line is walked pin 16 as feet; Under the perfect condition, when crank-motion to horizontal level, the first walking pin 1, the second walking pin 10 and the third line are walked pin 16 and are kept in touch with ground simultaneously.
During operation, be that original position is an example with shown in Figure 4, when the crank of second double-crank mechanism 11 during from horizontal level 0 degree dextrorotation turnback, the third line is walked pin 16 as the feet close proximity to ground:
(1) when the crank of second double-crank mechanism 11 when promptly 0 degree dextrorotation turn 90 degrees from horizontal level, the first walking pin 1 moves forward with the second walking pin, 10 relative frames obliquely; Frame 5 relative feets, promptly the third line is walked pin 16, forward motion obliquely; When the crank dextrorotation of second double-crank mechanism 11 goes to 90 when spending, the first walking pin 1 and second pin 10 of walking is lifted to highest point;
(2) when the crank of second double-crank mechanism 11 when vertical position 90 degree continue dextrorotations and turn 90 degrees, the first walking pin 1 moves under oblique forward with the second walking pin, 10 relative frames; The relative feet of frame, promptly the third line is walked pin 16, oblique forward motion down; When the crank dextrorotation of second double-crank mechanism 11 goes to 180 when spending, the first walking pin 1 and second pin 10 of walking contacts with ground once more;
When the crank of second double-crank mechanism 11 when promptly 180 degree continue the dextrorotation turnbacks from horizontal level, the first walking pin 1 and second is walked pin 10 as the feet close proximity to ground:
(3) when the crank of second double-crank mechanism 11 when horizontal level 180 degree dextrorotations turn 90 degrees, the third line is walked pin 16 relative frames and is moved obliquely forward; The relative feet of frame, the i.e. first walking pin 1 and the second walking pin 10, motion obliquely forward; When the crank dextrorotation of second double-crank mechanism 11 goes to 270 when spending, the third line is walked pin 16 and is lifted to highest point;
(4) when the crank of second double-crank mechanism 11 when vertical position 270 degree continue dextrorotations and turn 90 degrees, the third line is walked pin 16 relative frames and is moved obliquely forward; The relative feet of frame, the i.e. first walking pin 1 and the second walking pin 10, motion obliquely forward; When the crank dextrorotation of second double-crank mechanism 11 goes to 360 when spending, the third line is walked pin 16 and is contacted with the face of land once more, returns to shown in Figure 4.
So repeatedly, the first walking pin 1 and the second walking pin 10 are walked pin 16 with the third line and are leapfroged, and realize the walking function of rice transplanter.
