Embodiment 1

[0027] Please combine Figure 2 to Figure 6 As shown, a kind of shock-absorbing stick structure of the present invention, stick comprises front box body 5, protective shell 6, shock-absorbing device 7 and rear box body 50, and front box body 5 and shock-absorbing device 7 are fixedly connected by bolt 19 , the shock absorber 7 and the rear box 50 are fixedly connected by bolts 19, and the protective shell 6 is installed on the shock absorber 7 and the rear box 50 by fixing bolts 24, wherein:

[0028] Front box body 5 is made up of front support 8, front side plate, middle support 11, butter pipe 12, bottom reinforcing plate 13, reinforcing rib 14, middle side plate and front box body fixing block 17, and middle support 11 and butter pipe 12 are set In the front side plate, the middle support 11 is used to connect other working devices, one end of the middle side plate is connected to the front box body fixing block 17, and the front box body fixing block 17 is provided with a ...

Embodiment 2

[0039] In this embodiment, the basic stick structure is the same as that of the first embodiment, the difference is that the stick damping device 7 is not unique, and can also be other damping methods, such as air pressure damping method or oil pressure damping method , as long as the shock absorbing effect between the front box body 5 and the rear box body 50 can be ensured, its specific implementation method is the same as that of the first embodiment, and will not be repeated here.

Embodiment 3

[0041] In this embodiment, the basic stick structure is the same as that of the first embodiment, the difference is that the connection between the front box body 5 and the protective shell 6 and the rear box body 50 is not fixed as a bolt connection, but can also be connected by a mortise and tenon joint. Type structure or any other connection structure connection, as long as the middle box can be guaranteed to be detachable, its specific implementation is the same as the first embodiment, and will not be repeated here.

Abstract

The invention discloses a damping bucket rod structure and an excavator. According to the damping bucket rod structure and the excavator, a front case, a protective shell, a damping device and a rear case are fixedly connected through bolts; the front case is composed of a front bearing, a front plate, a middle bearing, a grease pipe, a bottom reinforcing plate, reinforcing ribs, a middle plate and front case fixing blocks; the damping device is composed of guide rods, bolts, a front case cushion plate, springs and a rear case cushion plate; the rear case is composed of rear case fixing blocks, a top plate, side plates, a bottom plate, a central bearing, a rear plate, a bent plate and rear side plates, wherein the rear case fixing blocks are connected with the top plate and the bottom plate, the side plates are fixed at the top of the rear plate, the bent plate is arranged at one end of the rear plate, the rear side plates are mounted on the bent plate, and the central bearing is mounted on the lower portion of the rear side plate. The damping bucket rod structure achieves a damping function and can simultaneously protect bucket rods, swing arms, a bench, a lower unit and the like, thereby improving the integral use security and practicality. By means of a modularized design, the damping bucket rod structure is convenient to manufacture and reduces the use cost and the maintenance cost.

Description

technical field [0001] The invention relates to the technical field of an excavator arm, in particular to a shock-absorbing arm structure and an excavator. Background technique [0002] In known excavator sticks, the length of the stick is basically a fixed length, and the free change of the length cannot be realized. During use, as the working conditions change, it is often necessary to change the structural protection stick and boom to customize the short stick or extend the boom to achieve its adaptability, resulting in an increase in customer use costs and maintenance costs . In addition, under special working conditions, the current stick cannot adjust the digging force during use, which also limits the adaptability of the excavator to working conditions. [0003] Chinese patent CN201010200722 discloses an excavator arm, which includes a backing plate 104 and an anti-collision strip 105, the top surface of the anti-collision strip 105 is provided with a groove 106 tra...
