Description
Technical field
Technical field of engineering machinery is the utility model is related to, especially a kind of working device of loader.
Background technology
Equipment is one of important component on engineering machinery loading machine, can be realized by different working mechanisms whole
Machine difference in functionality.Loading machine often includes vertical lifting mechanism and six bar mechanism, eight-bar linkage with equipment at present, vertically
Lifting mechanism can control the load arm of force well in lifting process, can meet bigger lifting load with smaller main screw lift
It is required that being contrasted with other linkages, the part that vertical lifting mechanism uses is more, and is all arranged among equipment
Position, its arrangement space is limited, and mechanism is compact, is unfavorable for equipment rotating bucket arrangement of mechanism, cause rotating bucket mechanism digging force and
Certain defect be present in flip angle and the design of other accessories.The rotating bucket mechanism of existing working device of loader include scraper bowl pull bar,
Rocking arm, rocker arm support and swing arm, rocker arm support are fixed on mobile beam, are articulated with the middle part of rocking arm on rocker arm support, rocking arm
Bottom and one end of scraper bowl pull bar be hinged, the other end and the scraper bowl of scraper bowl pull bar are hinged, the loading machine of this rotating bucket mechanism
Equipment has the following disadvantages：1st, rotary ink tank arrangement space is too small, causes oil cylinder stroke short, is unfavorable for equipment turn up
Power and mechanism rotational angle optimization；2nd, equipment rocking arm and scraper bowl gap are too small, and two kinds of part movements are in opposite direction, lead
Cause arrangement of parts insufficient space.Solution meets that part arranges needs by changing the contour structures of front end bucket at present,
Such as reduce scraper bowl subtended angle, reduce equipment and receive bucket angle to meet institution requests, angle change has influence on to a certain extent
Scraper bowl performance, scraper bowl bucket fill degree can be caused to be deteriorated, bucket configuration becomes complicated.
Utility model content
The purpose of this utility model is to provide a kind of working device of loader, and this device can solve scraper bowl and rotating bucket oil
The problem of cylinder arrangement space is small.
In order to solve the above problems, the technical solution adopted in the utility model is：This working device of loader includes tool
There is the swing arm of crossbeam, the rocker arm support being hinged with rocking arm is fixed with the crossbeam, the rocking arm passes through scraper bowl pull bar and shovel
Bucket is connected, and the bottom of the rocking arm is hinged with the rocker arm support and forms fixed hinge, upper end and the rotating bucket oil of the rocking arm
Cylinder is hinged to form hinge, and one end of the scraper bowl pull bar and the pin joint of the rocking arm are located at the fixed hinge and described
Between upper hinge.
In the technical scheme of above-mentioned working device of loader, more specifically technical scheme can also be：The scraper bowl pull bar
It is articulated with the middle part of the rocking arm.
Further, there is Automatic Levelling quadric chain, the other end of the rotary ink tank is articulated with described to be looked for automatically
The moveable hinge contact of flat quadric chain.
Further, the Automatic Levelling quadric chain includes the back link being hinged respectively with front frame and long company
Bar, the back link are connected with the long connecting rod by short connecting rod, and the rotary ink tank is articulated with the long connecting rod and described short
On the connection hinge of connecting rod.
By adopting the above-described technical solution, the utility model has the advantages that compared with prior art：Pass through
Change rotary ink tank, rocking arm and scraper bowl link point position control rocking arm and the mutual movement relation of scraper bowl, by rocking arm and rocking arm branch
The fixation hinge of frame moves to rocking arm bottom, and the pin joint of scraper bowl pull bar and rocking arm is located between fixed hinge and upper hinge, makes to turn
Bucket mechanism turns into positive rotation mechanism, so that scraper bowl is identical with the direction of motion of rocking arm, increases the arrangement of rotary ink tank and scraper bowl
Space, scraper bowl subtended angle can be increased, reduce scraper bowl BV values, improved scraper bowl performance, the work device front end visual field is further improved, to use
Family provides more preferable operating characteristics；Rotary ink tank is arranged in rocking arm upper end, and scraper bowl pull bar is arranged in rocking arm middle-end, beneficial to increase rotating bucket
The cylinder arm of force reduces the scraper bowl pull bar arm of force；In addition, fixed hinge moves to rocking arm bottom, equivalent to the radius of turn for increasing rocking arm,
Rotary ink tank be arranged in rocking arm upper end can allow rotary ink tank stroke design it is longer, rotary ink tank stroke is longer, and the arm of force is bigger,
Rotary ink tank ability becomes stronger, and working mechanism possesses bigger turn up ability.
Brief description of the drawings
Fig. 1 is equipment scheme of installation of the present utility model.
Fig. 2 is equipment rotating bucket structural scheme of mechanism of the present utility model.
Fig. 3 is equipment structural representation of the present utility model.
Embodiment
The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings：
Working device of loader shown in Fig. 1 to Fig. 3 includes being responsible for the lifting mechanism of lifting scraper bowl enhancing action and is responsible for
The rotating mechanism of scraper bowl rotary movement, lifting mechanism is by swing arm 1, back link 5, vehicle frame pull bar 4, connection bearing pin and front frame 11 etc.
Part forms, and being used as power set by boom cylinder 12 drives lifting mechanism to move, and is controlled in lifting process by vehicle frame pull bar 4
The distance of system lifting swing, the control load arm of force is swung in small range, so as to realize equipment vertical lifting.Rotating bucket machine
Structure mainly solves scraper bowl angle control problem in scraper bowl upset and lifting process, and the rotating bucket mechanism of the present embodiment is connected by front end four
Two sets of quadric chains of linkage and Automatic Levelling quadric chain are formed.Scraper bowl pull bar 2, scraper bowl 10, swing arm 1, rocking arm 3 form
Front end quadric chain, the rocker arm support 1-2 being hinged with rocking arm 3, the bottom of rocking arm 3 are fixed with the crossbeam 1-1 of swing arm 1
It is hinged with rocker arm support 1-2 and forms fixed hinge 9, rocking arm 3 is connected by scraper bowl pull bar 2 with scraper bowl 10, and scraper bowl pull bar 2 is be hinged
In the middle part of rocking arm 3, the upper end of rocking arm 3 is hinged to form upper hinge by upper hinge 8 and rotary ink tank.Because rocking arm 3 is fixed
Pin joint moves to bottom so that rocking arm 3 is identical with the direction of motion of scraper bowl 10, is formed and rotates forward quadric chain.Front end double leval jib knot
Structure mainly controls the flip angle of scraper bowl 10 and scraper bowl digging force size, the hinge position of rotary ink tank 13 to be arranged in the upper end of rocking arm 3, have
Beneficial to the bigger scraper bowl digging force of realization.The Automatic Levelling four that long connecting rod 7, short connecting rod 6, back link 5, front frame 11 form rear end connects
Linkage, back link 5 and long connecting rod 7 are hinged with front frame 11 respectively, and back link 5 and long connecting rod 7 are connected by short connecting rod 6,
One end of rotary ink tank 13 is articulated with the moveable hinge contact of Automatic Levelling quadric chain, i.e. rotary ink tank 13 is articulated with long connecting rod
7 and short connecting rod 6 connection hinge on.The purpose for setting Automatic Levelling quadric chain is that solve lifting mechanism and rotating bucket mechanism angle
Degree overturns asynchronous problem, controls rotating bucket flip angle in lifting mechanism lifting process to change by rear end four-bar linkage structure, makes
The suitable ground-angle change of scraper bowl is smaller.
