Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
The power shovel scraper bowl perspective view that Fig. 2 provides for the embodiment of the present invention, the power shovel scraper bowl front view that Fig. 3 provides for the embodiment of the present invention.As shown in Figures 2 and 3, embodiments providing a kind of power shovel scraper bowl, hinged fixing including bucket body 1 and sluice gate 2, sluice gate 2 and bucket body 1, pin joint is the H point in Fig. 3.Wherein, power shovel scraper bowl also includes support link 6 and connecting rod 7, support link 6 shown in Fig. 3 and connecting rod 7 are all the state disassembled with bucket body 1, first end of support link 6 is hinged with sluice gate 2 fixing, pin joint is E point, second end of support link 6 is hinged with connecting rod 7 fixing, and pin joint is I point；Connecting rod 7 is fixing to be hinged on bucket body 1.Support link 6 can be bending, is provided with multiple lightening hole 61, for loss of weight.
Support link 6 is provided with the first hinge hole (not shown) with hinged fixing can being accomplished in that of sluice gate 2 on the framework of sluice gate 2, the first end in support link 6 is provided with the second hinge hole 62, in the first hinge hole and the second hinge hole 62, wear the first latch 8, realize the hinged fixing of the two.
Similarly, support link 6 is similar with the hinged of connecting rod 7 and said structure, and the second end in support link 6 is provided with the 3rd hinge hole 63, and connecting rod 7 is through the 3rd hinge hole 63, so that support link 6 is hinged with connecting rod 7 fixing.
Connecting rod 7 can be fixed in several ways and is hinged on bucket body 1, preferably with installing hole 11 existing on bucket body 1, in connecting rod 7, fixed cover is provided with fast pulley 71, it is provided with for fixing hinged fixing hole 711 with bucket body 1 on fast pulley 71, the second latch 9 is utilized to be connected, as shown in Figure 2 with the installing hole 11 on bucket body 1 by fixing hole 711.
Sluice gate 2, support link 6 and connecting rod 7 constitute linkage, and when exerting a force connecting rod 7, support link 6 and sluice gate 2 produce and interlock such that it is able to control the keying of sluice gate 2.
