Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figures 1 to 4, according to a kind of controllable multiple-connecting-rod formula digging mechanism of the specific embodiment of the invention, comprising: frame, swing mechanism, upset digging mechanism, act descending mechanism and drive unit.
As shown in Figure 1 to Figure 2, swing mechanism comprises: the first driving lever 2, second driving lever 14, large arm 4, first connecting rod 6 and second connecting rod 17, one end of first driving lever 2 is articulated with in frame 22 by revolute pair 1 and one end of the second driving lever 14 is articulated with in frame 22 by revolute pair 13, and the second driving lever 14 is positioned at the front of the first driving lever 2, one end of large arm 4 is hinged by the other end of revolute pair 3 and the first driving lever 2, one end of first connecting rod 6 is hinged with the other end of large arm 4 by revolute pair 5, second connecting rod 17 is in bending and one end of second connecting rod 17 is hinged by the other end of revolute pair 15 and the second driving lever 14, the other end of this second connecting rod 17 is articulated with by revolute pair 7 on the lever arm of first connecting rod 6, can find out from Fig. 2, when the first driving lever 2 swings left, large arm 4 moves downward, thus drive first connecting rod 6 to move upward, and when the second driving lever 14 swings to the right, second connecting rod 17 moves upward, and makes first connecting rod 6 obtain the larger amplitude moved upward, otherwise then makes first connecting rod 6 move downward.
As shown in figures 1 and 3, upset digging mechanism comprises turning rod 9 and scraper bowl 11, and one end of turning rod 9 is hinged with the other end of first connecting rod 6 by revolute pair 8, and the top of scraper bowl 11 is hinged with the other end of turning rod 9 by revolute pair 10; When first connecting rod 1 moves upward, turning rod 9 also moves upward, thus the shovel mouth of scraper bowl 11 is moved downward, and realizes excavating action, otherwise then makes the shovel mouth of scraper bowl 11 move upward.
