And the distance of the 5th connecting rod 20 two pin joints in top is equal, form double-crank double parallel mechanism.
The all rod members being connected with the first connecting shaft 27 and the second connecting shaft 26 of the present invention can be only in big scraper bowl
24 side is arranged it is also possible to be symmetrical arranged in the both sides of big scraper bowl 24, in order that rod member uniform force is it is easy to control, two
Side is symmetrical arranged preferably.
The operation principle of dump truck of the present invention is as follows:
1st, rotation is passed to motor connection axle 5 by shaft coupling 9 by motor 4, by bidirectional clutch 32 and the first empty set
The joint of gear 30 or the second free gear 33 controls it to rotate or stopping (first free gear 30 or the of the present invention with separating
Two free gears 33 can not rotate simultaneously, and the present invention is also not required to it moves simultaneously, if need to move simultaneously, can be empty by each
Sleeve gear respectively installs a clutch).
2nd, when needing to control the first free gear 30 to rotate, bidirectional clutch 32 is engaged, then the first empty set tooth
Wheel 30 drives the rotation of the first fixed gear 31 nibbling sum therewith, and the first fixed gear 31 drives the first connecting shaft 27 to rotate, the
One connecting shaft 27 drives the first driving lever 3 being connected thereon to rotate with it, and the first driving lever 3 is by the first fraising 2
Pass motion to first connecting rod 6, first connecting rod 6 drives third connecting rod 15 around 13 turns of the 3rd fraising by the 6th fraising 19
Dynamic, thus driving small scraper pan 14 to rise or fall action.
3rd, when needing to control the second free gear 33 to rotate, bidirectional clutch 32 is engaged, the second free gear
33 drive the second fixed gear 34 nibbling sum therewith to rotate, and the second fixed gear 34 drives the second connecting shaft 26 to rotate, and second even
Spindle 26 passes motion to the second driving lever 10, and the second driving lever 10 passes motion to second connecting rod by the second fraising 7
11 (because the second driving lever 10, fourth link 17 and two, 20 top of the 5th connecting rod hinge spacing are equal, therefore, shapes
Become double-crank double parallel mechanism), second connecting rod 11 passes motion to fourth link 17 and the 5th by the 5th fraising 18 and connects
Bar 20, makes the 5th connecting rod 20 around the 7th fraising 21 rotation by two parallel-crank mechanisms, thus driving small scraper pan 14 to overturn.
4th, the process that small scraper pan 14 shovels article is: motor 4 is first passed through bidirectional clutch 32 and engaged with the first free gear 30
Controlling small scraper pan 14 to decline (controls small scraper pan 14 can change the attitude of small scraper pan 14 during declining in motor 4, by suitable
Design rod length can reduce the change of small scraper pan 14 attitude), then pass through bidirectional clutch 32 and the second free gear 33
Engagement Control small scraper pan 14 rotates to the correct position of shovel article, shovels into rubbish during car body 1 is moved forward, and controls double after having shoveled
Engage with the first free gear 30 to clutch 32, small scraper pan 14 is given rise to position shown in Fig. 1, finally again by bidirectional clutch
32 are engaged with the second free gear 33, control small scraper pan to pour rubbish in big scraper bowl 24 into, so repeatedly fill big scraper bowl 24
For this.
