A working device, with coupling means for operatively coupling it to a vehicle, which means form a quick coupling, comprises, on a rear side of a bucket ( 1 ), a supporting plate ( 8 ) supporting a first portion of the constructional elements forming the quick coupling, whereas a respective end portion of the vehicle arms has a further supporting plate ( 14 ), which is driven by a cylinder-piston unit ( 21 ), and supports a further portion of the quick coupling forming constructional elements.

Description

Band can be operated the equipment of the mechanism that is attached to vehicle

Technical field

The present invention relates to a kind of equipment, comprise the coupling mechanism that operationally this equipment is attached to vehicle.

Background technology

Well-known, in agricultural or construction machine, be necessary to replace employed operating equipment with another instrument continually, to carry out other type of operation.

Nowadays, for example, replace existing machining tool with another equipment with some different technologies features, described another equipment is for example by the scraper bowl that free end supported of the lift arm of vehicle, this replacement is carried out by mechanically actuated, wherein vehicle operator must withdraw from driving cabin carrying out the manual clutch operation, to install and be connected by carrying out multiple different manual operation, particularly installs and is connected hydraulic fluid supply and bleed off pipe.

Therefore, carry out above-mentioned manually operated needs and make that the replacing operation of machining tool is very complicated, and it must be carried out by skilled vehicle operator.In addition, aforesaid operations must be carried out by the operation required time at the scene, therefore causes Work machine undesirably to shut down considerable time.

Summary of the invention

Therefore, the objective of the invention is to allow equipment, such as scraper bowl, hay mover or similarly be easy to the device dismantled, in rapid and safe mode, at tool using not and do not force vehicle operator to leave under the situation of vehicle, ressemble respectively on the front side of the lift arm of an operation vehicle or decline arm.

Above-mentioned target reaches by a kind of equipment, this equipment comprises the coupling mechanism that operationally it is attached to a vehicle: wherein on the rear side of scraper bowl, be provided with a base plate of the first that is used to support the structural member that forms described quick connection; And the respective end of wherein said each arm of vehicle has comprised the another base plate that can be driven by the piston cylinder assembly, and it is used to support another part of the described structural member that forms described quick connection.

The specific embodiment

As shown in fig. 1, interchangeable scraper bowl 1 mechanical attachment extremely, the front portion 2 of included a plurality of arms in lift arm that for example in agricultural or building operation, use, the operation vehicle and the decline arm.

Figure 1 illustrates shovel bucket 1, but should it is evident that, also can provide by other device of hydraulically operated or apparatus, and they correspondingly need quick connection, operationally be connected to hydraulic pressure center cell known type own, the operation vehicle with scraper bowl with instrument 1.

Fig. 2 illustrates, in lateral view, comprised the scraper bowl 1 of known mechanisms 3 own on its rear side, have: for example, the lower tube linear element of each arm front portion of one pedestal 4 and another pedestal 5 and operation vehicle, described pedestal is used to be provided to the mechanical connection of topcross element 6.Movable instrument comprises the base plate 8 that stretches out from the rear wall of scraper bowl 1.

Described base plate 8 is supporting the structural member that forms the groove part that connects fast, mainly identifies with reference number 9, discloses described structural member below with reference to Fig. 3 in more detailed mode.

Fig. 3 is the detail drawing that the base plate 8 that stretches out from scraper bowl 1 is shown.

Described base plate 8 is supporting the fluted body element 11 that connects fast, two centering sleeves 13 that are used to pin centering separately and two floating support elements 12 that plate 9 are connected to base plate 8.

As shown in Figure 4, arm 2 is included in its another piece plate 14 and opening 13 on the side of plate 9, and described another plate 14 comprises the plush copper element 15 of quick connection, and this plush copper element can be connected to groove elements 11; The alignment pin 10 that described opening 13 is used for being arranged on this place equally is contained in wherein.

Also might generally find out bite and clamping element 25, be used to clamp corresponding slip column, described slip column is identified by reference number 16 in Fig. 5.

Fig. 5 is connected in the preceding front view of its attended operation fast.

It is clear herein that what illustrate is to stretch out the plate 14 of centring pin 10, and the plush copper element 15 that connects fast.

The assembly that comprises plate 14 is supported slidably by pillar 16.

Fig. 1 also shows mainly by reference number 20 signs and the leverage that driven by piston cylinder unit 21, and described piston cylinder unit 21 controllably drives in order from the operation vehicle cabin.

The leverage 20 that illustrates preferably in Fig. 5 is activated or is driven by piston cylinder unit 21, and operationally is connected to carriage 22, and this carriage 22 forms one with the described pillar 16 that effectively is attached to described plate 14.

Therefore,, can carry out translational motion (arrow f), make

parts

10,15 be coupled to re-entrant part 10,13 (Fig. 3) thus, thereby the quick connection that is fully assembled is provided towards plate 9 by application piston 21, plate 14 plush copper element 15 and sell 10 in addition.

Fig. 6 shows and is positioned at the leverage 20 that activated the position, and it is in by the operating mode that rod member drove of piston cylinder unit 21.

Plate 14 is driven by the direction shown in the arrow (f) in Fig. 6 together with pin 10 and ingredient 15 (Fig. 5), and correspondingly, groove coupling assembly 9 has held nose assembly 14 ground and given prominence to element, quick connection is mounted and correct running.

Fig. 6 shows a tolerance compensating system, mainly by reference number 30 signs.This system comprises a screw element 31, packing ring 32, and by inserting the centring pin 10 of plate 14 wherein, is pushed in the corresponding sleeve 13 of plate 9, thereby allows the radial compensation of the common displacement of two plates, so that accurate assembling to be provided.

By with cavity 4 and 5 and the

tube element

6 and 7 of the arm front portion of vehicle fit together, thereby mechanically connect after the scraper bowl 1, application piston tube Unit 21 connect each

structural member

13,11 that forms the ingredient that groove connects fast herein so that leverage drives forwards plate 14 and

element

15,10 towards plate 9.

The advantageous particularly part is that one is promptly true among the present invention, carry out moving or driving by piston cylinder unit 21 to plate 14, described piston cylinder unit 21 has been used to selected operation tool, for example scraper bowl 1, be supplied to the mechanical attachment of arm front portion 2, and described arm front portion is included in the lifting of an operation vehicle gradually or in the decline assembly.

Particularly, the realization of the motion of plate 14 and associated

components

13,15,16 is because the structure of the leverage that is identified by reference number 50 in Fig. 5.

Advantageously, the translation of plate 14 and member thereof or slip are to finish under any situation about rotatablely moving not taking place, and this is owing to the structure of the pillar 16 that slides in corresponding sleeve, and corresponding sleeve is illustrated by reference number 26 diagrams.

Be dismounting scraper bowl 1, the separated disengagement of member of the member of assembly 9 and assembly 10 allows to dismantle easily scraper bowl 1 or other operating means thus.
