The course of work and principle:
When scraper bowl 16 needs inwardly to overturn, motor drives the first driving link 2 to make it turn clockwise around the first revolute pair 1, thus promotion first connecting rod 4 moves right, and the first bracing frame 6 is turned clockwise around the 23 revolute pair 43; First bracing frame 6 promotes the second bracing frame 10 by the first expansion link 8 again, and the second bracing frame 10 is turned clockwise around the 24 revolute pair 45; The rotation of the second bracing frame 10 makes the second expansion link 12 and second connecting rod 14 produce thrust, orders about scraper bowl 16 and inwardly overturns.In like manner, when scraper bowl 16 needs outwards to overturn, motor drives the first driving link 2 to be rotated counterclockwise around the first revolute pair 1, then pulls first connecting rod 4 to left movement, and the first bracing frame 6 is rotated counterclockwise around the 23 revolute pair 43; First bracing frame 6 pulls the second bracing frame 10 by the first expansion link 8 again, and the second bracing frame 10 is rotated counterclockwise around the 24 revolute pair 45.The rotation of the second bracing frame 10 makes the second expansion link 12 and second connecting rod 14 produce pulling force, orders about scraper bowl 16 and outwards overturns.
When scraper bowl 16 needs to rise, motor drives the second driving link 18 to make it be rotated counterclockwise around the 9th revolute pair 17, second driving link 18 orders about third connecting rod 20 and pulls the 3rd bracing frame 22 left, 3rd bracing frame 22 is rotated counterclockwise around the 23 revolute pair 43, and pulling force is left produced to the 3rd expansion link 24, because swing arm 37 and swing arm push rod 44 do not move, therefore dipper 26 is under the pulling force effect of the 3rd expansion link 24, with the 24 revolute pair 45 for the point of rotation is rotated counterclockwise, dipper 26 rotarily drive dipper push rod 27 and scraper bowl 16 rises.In like manner, when scraper bowl 16 needs to decline, motor drives the second driving link 18 to make it turn clockwise around the 9th revolute pair 17, second driving link 18 orders about third connecting rod 20 and promotes the 3rd bracing frame 22 to the right, 3rd bracing frame 22 is turned clockwise around the 23 revolute pair 43, promote the 3rd expansion link 24 to the right again in rotary course, thus make dipper 26 with the 24 revolute pair 45 for the point of rotation turns clockwise, dipper 26 rotarily drive dipper push rod 27 and scraper bowl 16 declines.The rising of scraper bowl 16 and descent path are all curved.
Motor drives the 4th driving link 41 to make it occur clockwise around the 22 revolute pair 42 or be rotated counterclockwise, 4th driving link 41 clockwise or be rotated counterclockwise six-bar linkage 39 can be driven to the right or to left movement, because six-bar linkage 39 is connected with swing arm 37, therefore six-bar linkage 39 can drive swing arm 37 to rotate around the 19 revolute pair 36, and swing arm 37 drives scraper bowl to overturn assembly, scraper bowl lifting assembly and scraper bowl 16 by the first bracing frame 6 and the 3rd bracing frame 22 again and swings up and down.
When needing the digging radius adjusting excavator, motor drives the 3rd driving link 34 to make it occur clockwise around the 18 revolute pair 35 or be rotated counterclockwise, 3rd driving link 34 drives swing arm push rod 44 by the 5th connecting rod 32, make swing arm push rod 44, on swing arm 37, stretching motion occur, when arriving assigned address, then fixed the position of swing arm push rod 44 by the locking of motor; When stretching motion occurs swing arm push rod 44, the first expansion link 8, second expansion link 24 will extend simultaneously or retract, and be locked, assisted expanding-contracting action during a certain position of same arrival by rod member retaining mechanism.The stretching motion of swing arm push rod 44, first expansion link 8 and the second expansion link 24 have adjusted the digging radius of excavator.
When needs adjustment excavation depth, the 5th driving link 47 drives dipper push rod 27 to occur to stretch on dipper 26 by seven-link assembly 49, when after assigned address on earth, is fixed the position of dipper push rod 27 by motor locking mechanism.Second expansion link 12 extends with the flexible of dipper push rod 27 accordingly or shrinks, and is locked, assisted expanding-contracting action when arriving a certain position by rod member retaining mechanism.A rotation period of drive motors can complete once stretching of dipper push rod 27 in this process.The excavation depth of the flexible adjustable scraper bowl 16 of dipper push rod 27 and the second expansion link 12.
In sum, digging mechanism of the present invention is rational in infrastructure, diverse in function, there is scraper bowl upset and elevating function, movable arm swinging function, regulate digging radius and regulate excavation depth function, especially regulate digging radius and regulate excavation depth function, can under the prerequisite of excavator base machine not movement, expand digging radius and/or increase excavation depth, make digging mechanism of the present invention not only can complete the basic function of excavator, and can at some condition (such as height rescue, disassemble high building, the mud prune job in riverbed, domatic operation etc.) time better finishes the work, realize a tractor serves several purposes, and it is more time saving and energy saving.
It is pointed out that above-mentioned preferred embodiment is only and technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
