Abstract
The utility model discloses a single handle operating mechanism for loader, which comprises an operating tank, an operating handle, an operating rod, a dustproof cloth, tie rods, a movable arm connecting cover and a rotating connecting cover. Bottom of the operating rod is provided with a connecting sheet through a pin shaft. The operating rod and the connecting sheet are respectively connected with the movable arm connecting cover and the rotating connecting cover through two tie rods. The movable arm connecting cover and the rotating connecting cover are respectively connected with a movable arm valve rod of a multiple-way valve and a rotating valve rod through two tie rods. The utility model has reasonable structural design and convenient and flexible operation, which can realize the lifting of the movable arm of loader and overturn of the bucket by single handle operation.
Description
The utility model belongs to the loader technical field, relates to a kind of loader mono-lever control mechanism, the operating mechanism that particularly a kind of monolever control loading arm and scraper bowl move.
The loader stick control mechanism of prior art mostly adopts two control cranks to control the lifting of loading arm and the upset of scraper bowl respectively, both can not take into account, in the lifting process of swing arm, can not realize the upset of scraper bowl simultaneously, thereby the operator must frequently change control crank, handle inconvenience, labour intensity is bigger.
The purpose of this utility model provide a kind of can handled easily the loader mono-lever control mechanism of upset of the lifting of loading arm and scraper bowl, to overcome the deficiencies in the prior art.
For achieving the above object, the utility model has been taked following technical scheme: it comprises operation panel, control crank, control stick, dirt-proof boot, pull bar, swing arm connection adapter sleeve, rotating bucket connection adapter sleeve, and the control stick bottom is provided with contiguous block, connects by bearing pin; Control stick and contiguous block respectively by two pull bars and swing arm join adapter sleeve, rotating bucket connection adapter sleeve links to each other; Swing arm connection adapter sleeve, rotating bucket connection adapter sleeve link to each other with swing arm connection valve rod, the rotating bucket connection valve rod of banked direction control valves by two pull bars respectively.
For make the utility model do not need to annotate lubrication oil or lubricating grease just can go slick, durable in use, respectively between rotation counterpart contiguous block and bearing pin, swing arm connection adapter sleeve joins adapter sleeve with lower support between centers, rotating bucket and the lower support between centers is provided with wear-resisting composite material axle sleeve.
For making the pull bar that transmits motion can adapt to the distance in the transmittance process and the variation of angle automatically, at the pull bar two ends oscillating bearing or bearing pin are set, the jackshaft of pull bar connects with oscillating bearing or bearing pin by screw thread, and the two ends thread rotary orientation is opposite, thus pull bar length can regulated at will to adapt to the needs that operating mechanism is adjusted.
The utility model reasonable in design, easy to operate, flexible, can handle the lifting of loading arm and the upset of scraper bowl by the monolever operation.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model master TV structure schematic diagram;
Fig. 2 is the utility model left side TV structure schematic diagram;
Fig. 3 is an A-A partial sectional view among Fig. 1;
Fig. 4 is a B-B partial sectional view among Fig. 1.
2 is control stick among the figure, and control crank 1 is fixed on the control stick 2 by thread connection, and control stick 2 bottoms are provided with contiguous block 11, connects by bearing pin 10; Control stick 2 links to each other with swing arm connection adapter sleeve 14, rotating bucket connection adapter sleeve 16 by two pull bars 4,5 respectively with contiguous block 11; Swing arm connection adapter sleeve 14, rotating bucket connection adapter sleeve 16 link to each other with swing arm connection valve rod 18, the rotating bucket connection valve rod 19 of banked direction control valves 20 by two pull bars 8,7 respectively.This operating mechanism is by two bolsters 12 up and down and 13 supportings on the fixed mount 6, fixed mount 6 by bolt on operation panel 21.
When control crank 1 seesaws, drive control stick 2 (welded together) around 12 rotations of upper support axle with following cambered plate, driving pull bar 4 moves up and down, cause that swing arm connection adapter sleeve 14 is around 13 rotations of lower support axle, it is reciprocating to drive swing arm connection valve rod 18 by pull bar 8 again, two hydraulic fluid port break-makes of control banked direction control valves 20 swing arms connection realize loading arm lifting, decline and the action of floating.
When control crank 1 side-to-side movement, drive control stick 2 around bearing pin 10 rotations, driving pull bar 5 moves up and down, cause that rotating bucket connection adapter sleeve 16 is around 13 rotations of lower support axle, it is reciprocating to drive rotating bucket connection valve rod 19 by pull bar 7 again, two hydraulic fluid port break-makes of control banked direction control valves 20 rotating buckets connection realize leaning forward and the hypsokinesis action of loading shovel.
Because swing arm and rotating bucket two cover controlling organizations are relatively independent, the also mutually noninterfere and move in all around of control crank 1, therefore can lift the rotary movement that scraper bowl is realized in the optional position that falls in the process at swing arm, also can lift and fall action at the realization swing arm of the optional position in the switching process of scraper bowl.
