Problems solved by technology

However, after the boom is lengthened, when grabbing nearby materials, since the connecting seat of the traditional grabbing wall is fixed on the rear end of the boom, the oil cylinder of the log grab still needs to use the rear end of the boom as the fulcrum. Driving the arm to rotate is far away from the center of gravity of the arm, and requires a large driving force, which makes the movement slow
In addition, after the length of the arm increases, the length extending out of the log grab increases accordingly, making the entire log grab take up a larger space, which is not conducive to transportation.

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the material grabbing arm for a log grab of the present invention includes a first arm 1 , and a connecting seat 5 is arranged on the outside of the first arm 1 . The connecting base 5 is connected with the first arm 1 through a position adjustment mechanism, so that the connecting base 5 can move longitudinally of the first arm 1 .

[0020] Such as figure 2 , image 3 and Figure 4 As shown, the position adjustment mechanism includes a strip-shaped support plate 10, a plate surface of the support plate 10 is welded to the outer wall of the first arm 1, so that they are fixedly connected, and the support plate 10 The longitudinal direction is consistent with the longitudinal direction of the first arm 1 , and limit blocks 6 are provided on the outer walls of the first arm 1 corresponding to both ends of the support plate...

Abstract

The invention relates to a timber grab assembly, in particular to a three-section type grabbing arm which is arranged on a timber grab, connected with an operation arm and used for increasing the work radius of the timber grab. The three-section type grabbing arm comprises a first arm rod, and a connecting seat is arranged on the outer side of the first arm rod. The three-section type grabbing arm is characterized in that the connecting seat is connected with the first arm rod through a position adjusting mechanism, and therefore the connecting seat can move in the longitudinal direction of the first arm rod. The timber grab using the grabbing arm is flexible in operation, occupied space is small, and transport is quite convenient.

Description

technical field [0001] The invention relates to a log grab assembly, in particular to a three-stage material grab arm connected with an operating arm on the log grab and used to increase the working radius of the log grab. Background technique [0002] The log grab is a kind of machinery for loading, unloading and handling of wood, timber and various strip materials. It is evolved from a hydraulic excavator. The biggest difference from a hydraulic excavator is the front-end working device. The front end of an ordinary excavator is a bucket, and the front end of a log grab is a wood grabber. [0003] The material grabbing arm of a traditional log grab includes an arm bar, and a connecting seat is fixed at the rear end of the arm bar outside. During use, the arm is hinged on the operating arm of the log grab through the connecting seat, and the front end of the arm is connected with the log grab of the log grab. When working, use the oil cylinder of the log grab to push the ...
