Component of the scraper bowl together with itself cooperative motion together.During mining Face-shovel Hydraulic Excavator operation, it is not only played
The effect for connecting the linking arm of swing arm and scraper bowl, there are also the effects for transmitting and bearing operating load.
The bucket rod structure of existing mining Face-shovel Hydraulic Excavator is mostly used by multiple metal plates with different thickness
The box-structure being welded.Specific constructive form is referring to attached drawing 1.Such structure itself designs complexity, and weight is larger, and ten
Divide the operating efficiency for influencing hydraulic excavator for mine.
Summary of the invention
In order to improve the operating efficiency of mining Face-shovel Hydraulic Excavator, the light weight of mining Face-shovel Hydraulic Excavator dipper is realized
Change design, the present invention provides a kind of bucket rod structure of new mining Face-shovel Hydraulic Excavator.
The technical scheme is that
The bucket rod structure of hydraulic excavator for mine, in the junction of dipper and boom cylinder and bucket arm cylinder, be provided with by
Semi-closed structure 5 composed by multiple metal plates with center hole, two vertical with the axial line of semi-closed structure 5 vertical
Into plane, it is respectively arranged with the symmetrical sector structure of two panels；
Sector structure is by the upper surface of semi-closed structure 5, anisotropically six roots of sensation branch is arranged in scattering in fore-and-aft plane
Strut 6.The end of support rod 6 is connected as one with loaded girder 1, and loaded girder 1 is arc-shaped.First support rod of front end
It is connected with the hinge means 2a of scraper bowl, the six roots of sensation support rod of rear end is connected with the hinge means 2b of swing arm.The branch of dipper front end
Strut distribution density is less than the support rod distribution density of dipper rear end.The middle part of first support rod of front end is supported to the 5th
Bar and loaded girder junction are provided with arc-shaped connecting rod 7, and the bending direction of arc-shaped connecting rod 7 is identical as loaded girder 1, arc
Connecting rod 7 is also connected with second support rod, third root support rod, the 4th support rod；
Connection is parallel to the lateral connection of the axial line of semi-closed structure 5 between the loaded girder 1 of two panels sector structure
Bar.
Preferably, loaded girder 1, transverse connecting rod, support rod 6, arc-shaped connecting rod 7 are all made of hollow cylinder bar.
The beneficial effects of the present invention are:
The present invention utilizes existing hollow cylinder section profile, devises a kind of light-weighted mining crowd shovel hydraulic excavating
The bucket rod structure of machine.The structure uses existing open circles section profile, reduces the difficulty of processing of design and material.In addition, compared with
The box-structure of original dipper, weight ratio original structure of new construction under the premise of guaranteeing use intensity and rigidity mitigate 25%.
The light-weighted design of the present invention not only saves material and cost, and improves mobility and mining crowd shovel liquid that dipper moves
Press the work production efficiency of excavator.

Specific embodiment
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.
The bucket rod structure of hydraulic excavator for mine, in the junction of dipper and boom cylinder and bucket arm cylinder, be provided with by
Semi-closed structure 5 composed by multiple metal plates with center hole, two vertical with the axial line of semi-closed structure 5 vertical
Into plane, it is respectively arranged with the symmetrical sector structure of two panels；
Sector structure is by the upper surface of semi-closed structure 5, anisotropically six roots of sensation branch is arranged in scattering in fore-and-aft plane
Strut 6.The end of support rod 6 is connected as one with loaded girder 1, and loaded girder 1 is arc-shaped.First support rod of front end
It is connected with the hinge means 2a of scraper bowl, the six roots of sensation support rod of rear end is connected with the hinge means 2b of swing arm.The branch of dipper front end
Strut distribution density is less than the support rod distribution density of dipper rear end.The middle part of first support rod of front end is supported to the 5th
