Description
Technical field
The present invention relates to broken rock to dig hook mechanical field, and in particular to a kind of digging hook rock arm forearm that the wing is shared with pressure.
Background technology
It is typically to be used for carrying out digging hook and rock is excavated, dug to dig hook rock arm, digs hook rock arm by size
Arm and digging hook are formed, and big forearm, which can play a part of dominating, digs hook action, wherein the large arm in big forearm is connected with frame, and arm
Longer, so being commonly called as large arm, forearm is connected with digging hook, and arm is smaller, so being commonly called as forearm.
The existing forearm for digging hook rock arm is divided into two kinds, and one kind is fixed digging hook rock arm forearm, one kind be with
The digging hook rock arm forearm of cylinder structure, the fixed structure for digging hook rock arm forearm generally include two clamping plates and dig hook plate,
Wherein two clamping plates are used to clamp digging hook plate, dig hook plate and instead of digging hook and otic placode that tradition is dug on hook rock arm forearm, this
The structure of sample is simple, and rock breaking efficiency is good, and digging hook plate, which has broken down, only need to change digging hook plate, without the entirety to digging hook rock arm forearm
Changed, therefore reduce maintenance cost, but dig hook plate be clamped in due to needing between left clamping plate and right clamping plate, generally compared with
It is thin, but larger impulsive force is born again, so, durability is bad, is easily damaged because of being impacted, if things go on like this,
Although maintenance cost is dug hook rock arm forearm compared to tradition and can still reduced, the amplitude reduced does not just reach the phase of people
Hope.
The content of the invention
It is an object of the invention to provide a kind of digging hook rock arm forearm that the wing is shared with pressure, solves existing clip type and digs
Hook rock arm digs hook clamping plate because the thickness low LCL of itself, the pressure excessive the problem of being easily damaged born.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of digging hook rock arm forearm that the wing is shared with pressure, including large arm bindiny mechanism and digging hook plate mechanism, the large arm connect
Connection mechanism includes the clamping plate that two pieces of in the vertical directions be arranged in parallel, and the top for digging hook plate mechanism is connecting portion, and connecting portion plugs
Between two clamping plates, connecting portion is connected by dismountable mode with two clamping plates, and the both sides dug in the middle part of hook plate mechanism are provided with
The pressure deployed to both sides shares the wing, and pressure shares the top of the wing and the bottom connection of clamping plate touches, and pressure shares the lateral surface of the wing
To be inclined, inclined direction is from top to bottom gradually to digging hook mechanism intermediate, inclined.
The relatively thin of the top setting of hook plate mechanism will be dug, can so coordinate two clamping plates to dig hook plate mechanism clamping well
Firmly, when carrying out broken rock with the forearm, the pressure come up by rock transmission can be by being arranged on the pressure dug in the middle part of hook plate mechanism
The wing is shared, is delivered on two clamping plates, the pressure that should be directly delivered to connecting portion originally has thus been shared, has made forearm more
Durable, the lateral surface that pressure is shared to the wing is arranged to inclined, first, in order to make it more attractive in appearance, second, being dug to be more convenient for
The bottom of hook plate mechanism sets female tooth.
As present invention further optimization, the top of large arm bindiny mechanism rear end is provided with oil cylinder of small arm head seat,
The bottom of two clamping plates is equipped with big forearm connection through hole in same position, and big forearm connection through hole is located at connects machine close to large arm
The position of structure rear end.
Large arm bindiny mechanism connects through hole by big forearm and is connected with large arm, and oil cylinder of small arm head seat is to be used for and large arm
What the oil cylinder of upper end was connected, just it can adjust the angle of forearm by controlling the oil cylinder of large arm upper end there is provided oil cylinder of small arm pole socket head
Degree.
As present invention further optimization, the inside of the clamping plate is provided with hollow cavity, and the surface of clamping plate is provided with
The inserts import and inserts outlet of empty inner chamber connection, the bottom angled of hollow cavity are set, hollow cavity bottom it is minimum
Place connects with inserts outlet.
Hollow cavity is set in the inside of clamping plate, just weightening material can be inserted into hollow cavity to inserts import,
It can so increase and dig the overall weight of hook rock arm forearm, and the increase for digging hook rock arm forearm overall weight can imitate its broken rock
Fruit is more preferable, when not needing forearm to have so heavy weight, opens inserts and exports, the fill material in hollow cavity is just in weight
Flowed out in the presence of power from inserts exit, weight reduction can save energy consumption.
As present invention further optimization, the outside of the inserts outlet is provided with outstanding connector, connects
Headring is exported around inserts and set, and the outer wall of connector is provided with connection screw thread.
Connector is set in the outside of inserts outlet, thus can connect a passage after inserts outlet is opened
On connector, enable material along passage, reach the stacking place of setting, the connection screw thread of connector is to be used for and guide
What the internal thread of pipe import was connected, while can also be connected with the internal thread of the lid for covering inserts outlet.
As present invention further optimization, the hollow cavity is located at the top of clamping plate.
The bottom of clamping plate will bear pressure, if its underpart is hollow structure, be more easily damaged, therefore hollow cavity is set
It is placed in the top of clamping plate.
As present invention further optimization, dismountable mode is led to for the bottom of two clamping plates provided with clamping plate grafting
Hole, the clamping plate grafting through hole on each piece of clamping plate is two or more, and the clamping plate grafting through hole of two clamping plates is correspondingly arranged, and clamping plate is inserted
Hole position is connected in close to the position of large arm bindiny mechanism front end, connecting portion is provided with fixed via, fixed via and clamping plate grafting
Through hole is correspondingly arranged, and connecting portion is connected with two clamping plates by being located in clamping plate grafting through hole with the bearing pin in fixed via.
Be connected between two clamping plates by the connection short column uniformly arranged, to dig hook plate mechanism be fixed when, only need by
Dig in the clamping gap between the connecting portion insertion two clamping plates of hook plate mechanism, the fixed via on connecting portion is directed at two pieces of folders
Clamping plate spliced eye on plate, after alignment, bearing pin is inserted, and can just complete to fix, such fixed form is simple, dismounting side
Just.
Compared with prior art, the present invention can at least reach one in following beneficial effect：
1. it is simple in construction, it is additionally arranged pressure and shares the wing, makes to act on a power part on connecting portion and share onto two clamping plates, because
This digging hook plate mechanism is more robust.
2. being provided with hollow cavity in the inside of clamping plate, it can at any time increase or decrease and dig the overall weight of hook rock arm forearm,
Make its rock breaking efficiency more preferable, more save energy consumption.
3. being provided with connector, the fill material in the hollow cavity of clamping plate directly can be discharged into appointed place, saved
Manpower and materials.
4. dig the convenient disassembly of hook plate mechanism.
