Compared with the prior art, the loader working device can meet requirements for performance of translational motion of the bucket in a lifting process of the moving arms.
Description
Technical field
The present invention relates to load mechanism technology for making field, especially a kind of equipment for loader fork dress.
Background technology
Along with the development of society, require to have more specialized feature to engineer machinery operation, especially in large-scale container fork dress field, require that the equipment of loader fork dress possesses the requirement of translation performance; And existing loader fork dress due to the linkage of equipment be all non-parallel-crank mechanism, therefore, in the process that swing arm promotes, scraper bowl turning over always more or less, is not well positioned to meet the requirement of translation performance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of working device of loader, and it can realize the performance requirement of swing arm scraper bowl translation in lifting process.
The technical scheme that technical solution problem of the present invention adopts is: this working device of loader comprises two two ends respectively by hinge A and hinge B and vehicle frame and the hinged swing arm of scraper bowl, swing arm described in every root all by be located at boom cylinder on hinge L and described vehicle frame hinged; Be provided with rocking arm between two described swing arms, described rocking arm is hinged by being located at rotary ink tank on hinge I and hinge J and described vehicle frame, and described rocking arm is hinged with the first long draw and the second long draw respectively by hinge G and hinge H; Be provided with by the hinged rocking bar of hinge F and hinge E between described first long draw and described second long draw, described rocking bar is hinged by being located at short rod on hinge D and hinge C and described scraper bowl; Described second long draw is provided with connecting rod, and the two ends of described connecting rod are fixedly connected on two described swing arms respectively;
Line between described hinge G to described hinge F to described hinge E to described hinge H to described hinge G is parallelogram; Line between described hinge B to described hinge C to described hinge D to described hinge E to described hinge B is parallelogram.
In above-mentioned working device of loader technical scheme, technical scheme can also be more specifically: the distance between described hinge A and described hinge J is equal with the distance between described hinge H and described hinge I; Distance between described hinge A and described hinge H is stretched between the maximum value of spacing of the described hinge after the limit and described hinge I and minimum value between described rotary ink tank.
Owing to have employed technique scheme, the present invention compared with prior art, the beneficial effect had is: owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, because hinge G to hinge F to hinge E to hinge H to hinge G between line be parallelogram, hinge B to hinge C to hinge D to hinge E to hinge B between line be parallelogram, the present invention is that parallelogram rotates forward eight-bar linkage, when swing arm is in the process promoted, parallelogram rotates forward the performance requirement that eight-bar linkage can meet scraper bowl translation, 2, because distance between hinge A and hinge J is equal with the distance between hinge H and hinge I, the distance between hinge A and hinge H is stretched between the maximum value of spacing of the hinge J after the limit and hinge I and minimum value between rotary ink tank, when the distance between rotary ink tank 2 length motion is to hinge J to hinge I equals the distance between hinge A to hinge H, hinge H to hinge I to hinge J to hinge A to hinge H between line be also parallelogram, the stroke of rotary ink tank remains unchanged, at this time promote boom cylinder and just can ensure that the angle on scraper bowl and ground remains constant in the process of whole lifting, ensure that the absolute translation of scraper bowl.

Fig. 2 is the P direction view of 1.
Fig. 3 is the schematic diagram of the ascending, descending process of the embodiment of the present invention.
Fig. 4 is the schematic diagram of the parallelogram rotating forward eight-bar linkage of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
It is hinged with vehicle frame by hinge A that working device of loader as shown in Figure 1, Figure 2, Figure 3 and Figure 4 includes the one end comprising two swing arms, 1, two swing arms, and it is hinged that the other end of root swing arm passes through hinge B scraper bowl 8; Every root swing arm 1 is all hinged by the one end being located at hinge L between hinge A and hinge B and boom cylinder 3, and the other end of boom cylinder 3 is hinged on vehicle frame by hinge K; Between two swing arms 1, Rocker arm 4 is installed; Rocker arm 4 is hinged with rotary ink tank 2 by the hinge I on it; rotary ink tank 2 is hinged with vehicle frame by hinge J, Rocker arm 4 by the hinge G on it and the first long draw 5 hinge, Rocker arm 4 pass through hinge H on it and the second long draw 9 hinged; Between the first long draw 5 and the second long draw 9, rocking bar 6 is housed, rocking bar 6 by hinge F and the first long draw 5 hinge, rocking bar 6 pass through hinge E and the second long draw 9 hinged; Rocking bar 6 by be located at hinge D on rocking bar 6 and short rod 7 hinged, 7 hinged by hinge C and scraper bowl 8 hinged; Second long draw 9 is provided with connecting rod 10, and connecting rod 10 and the second long draw 9 are welded to connect; The two ends of connecting rod 10 are fixedly welded on two swing arms 1 respectively; Hinge G to hinge F to hinge E to hinge H to hinge G between line be parallelogram, hinge B to hinge C to hinge D to hinge E to hinge B between line be parallelogram.
During work, because this working device of loader is that parallelogram rotates forward eight-bar linkage, when swing arm is in the process promoted, parallelogram rotates forward the performance requirement that eight-bar linkage can meet scraper bowl translation; 2, because distance between hinge A and hinge J is equal with the distance between hinge H and hinge I, the distance between hinge A and hinge H is stretched between the maximum value of spacing of the hinge J after the limit and hinge I and minimum value between rotary ink tank; When the distance between rotary ink tank 2 length motion is to hinge J to hinge I equals the distance between hinge A to hinge H, hinge H to hinge I to hinge J to hinge A to hinge H between line be also parallelogram, the stroke of rotary ink tank remains unchanged, at this time promote boom cylinder 3 and just can ensure that scraper bowl 8 remains constant with the angle on ground in the process of whole lifting, ensure that the absolute translation of scraper bowl.
