It addition, this utility model additionally provides a kind of asphalt pavement maintanance truck, equipped with above-mentioned on this asphalt pavement maintanance truck
Fully automatic hydraulic grab bucket feeding system described in any one so that asphalt pavement maintanance truck the most effectively solves
On market, asphalt pavement maintanance truck uses manual charging or feeds the difficult problem wasted time and energy by simple motor, steel wire rope,
And the feeding device overcoming the automaticity using oil cylinder to control higher needs hand charging more, feeding scope is little, and
Material stirring-up mechanism structure is complicated, it is relatively big to bear load, there is the defects such as potential safety hazard, and feasible system stretches any district of the radius of gyration
Being accurately positioned of asphalt in territory, automatically capture, swivel feeding and precisely discharging, automaticity is high, feeding distance is big,
Scope is wide, efficiently, the most time saving and energy saving.
As shown in Fig. 7,8,9,10,11, the operation principle of fully automatic hydraulic of the present utility model grab bucket feeding system is as follows:
When stock bin body 15 needs to load asphalt, act on blanking door 14 at feed bin door unlatching oil cylinder 13 and slowly open.This is
System uses luffing hydraulic jack to realize stretching, extension and the folding of arm, i.e. the piston rod 4-2 of luffing hydraulic jack 4 stretches out, will be flexible
Arm 5 stretches upwards, and hydraulic jack 7, grab bucket fixing seat 8 and grab bucket 9 is rotated and all moves upward, hopper 9 and grab bucket bearing
11 depart from, as shown in Figure 10, under the effect of luffing hydraulic jack 4 relative rotary column 3 maximum of telescoping boom 5 can realize β=
75 ° of foldings.
Such as Figure 10, shown in 11, in order to realize being accurately positioned of asphalt, pivoting support is used to realize 160 ° of system
Rotary operation, i.e. hydraulic motor 2-1 drive worm screw 2-2 and turbine outer ring 2-3 to rotate, and then drive rotary column 3 realize α=
Rotate in the range of 160 °.Under the effect of binodal hydraulic jack 6, arm II 5-2 realizes flexible along arm I 5-1, arm III 5-3 edge
Arm II realizes flexible.As shown in Fig. 8 state, the piston rod 4-2 retraction of luffing hydraulic jack 4, by telescoping boom 5 to next time
Receiving, hydraulic jack 7, grab bucket fixing seat 8 and grab bucket 9 are rotated and all move downward, hopper 9 is transferred to asphalt heap attached
Closely.
Such as Fig. 8, shown in 10, in order to realize the automatic crawl of asphalt, rotary hydraulic cylinder is used to realize grab bucket
Turn round and flexible, realize crawl and the discharging automatically of asphalt by grab bucket hydraulic jack, i.e. at rotary hydraulic cylinder 7
The effect fixing seat 8 of lower grab bucket not only can realize moving up and down, it is also possible to realizes 360 ° of rotations around cylinder body 7-1 axis.In grab bucket
Under the effect of hydraulic jack 10, two groups of grab buckets 9 can realize opening and closing in the range of γ=90 °, and then realizes automatically grabbing of asphalt
Taking, two groups of 9 bottoms of grabbing bucket are equipped with the some groups of 9-4 of resistance to roll flute, can effectively prevent material leakage when grab bucket 9 Guan Bi.
After asphalt has captured, the piston rod 4-2 of luffing hydraulic jack 4 stretches out, and is upwards stretched by telescoping boom 5
Exhibition, is rotated hydraulic jack 7, the fixing seat 8 of grab bucket and grab bucket 9 and all moves upward, and grab bucket is promoted to maximum height.Hydraulic motor
2-1 drives worm screw 2-2 and turbine outer ring 2-3 to rotate backward, and then drives rotary column 3 to reversely rotate, and rotates grab bucket 9 to material
Within warehouse 15 bin gate mouth scope, as it is shown in figure 9, the piston rod of grab bucket hydraulic jack 10 bounces back, two groups of grab buckets 9 are opened relatively,
Asphalt falls in stock bin body 15 under gravity, thus realizes the automatic discharging of asphalt.
Repeat aforesaid operations, after being full of appropriate number of asphalt in stock bin body 15, the work of binodal hydraulic jack 6
Stopper rod 6-2 bounces back, and arm II 5-2 bounces back along arm I 5-1, and arm III 5-3 bounces back along arm II 5-2.At grab bucket hydraulic jack 10
Effect under will grab bucket 9 closedown, pivoting support 2 act under telescoping boom 5 is rotated to correct position, luffing hydraulic jack 4
Piston rod 4-2 retraction, telescoping boom 5 is bounced back downwards, be rotated hydraulic jack 7, the fixing seat 8 of grab bucket and grab bucket 9 all to
Lower motion, until hopper 9 fits with grab bucket bearing 11, as shown in Fig. 1,6,7, system is in driving travel position.
Finally, under feed bin door opens oil cylinder 13 effect, close the feed bin door of stock bin body 15.
The fully automatic hydraulic grab bucket feeding system that this utility model provides, is fixed on asphalt pavement maintanance truck, can realize
Being accurately positioned of asphalt in hoisting arm expansion radius of gyration arbitrary region, automatically capture, swivel feeding and precisely discharging, solve
Asphalt pavement maintanance truck on market of having determined uses manual charging or feeds the difficulty wasted time and energy by simple motor, steel wire rope
Topic；Use pivoting support to realize 160 ° of rotary operations of system, realize the flexible of arm by hydraulic jack and fold, using rotation
Turn hydraulic jack realize the revolution of grab bucket and stretch, realize automatically capturing and unloading of asphalt by grab bucket hydraulic jack
Material, the feeding device effectively overcoming the automaticity using oil cylinder to control higher needs hand charging more, and feeding scope is little,
And material stirring-up mechanism structure is complicated, it is relatively big to bear load, there is the defects such as potential safety hazard；This system arm uses three-section type to hang
Arm, realizes flexible under binodal hydraulic jack drives, realizes 75 ° of foldings under luffing hydraulic jack effect, and position is various, has
Good passes through performance；And it is symmetrically placed to grab bucket, under the driving of rotary hydraulic cylinder, realize 360 ° of rotary operations, feeding distance
