Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings. refer to figure 1 , the connecting plate 2 is fixed on the bucket rod 1 of the hydraulic excavator through two pin shafts, which prevents the grabbing device from swinging and hitting the bucket rod 1 of the excavator during work, and increases the loading and unloading height; the universal joint 3 is formed by staggered The upper transmission pair 8 and the lower transmission pair 9 are arranged. The upper transmission pair 8 forms a movable connection with the connecting plate 2, and the lower transmission pair forms a movable connection with the rotary motor 4. Under the action of gravity, the grabbing device is always kept vertical. Straight posture; the rotary motor 4 with support and rotary joint function is installed on the connecting seat 5, and under the action of high-pressure hydraulic oil of the excavator, it can drive the connecting seat 5 to achieve 360-de...

Abstract

The invention discloses a pendulum feeding device of a hydraulic excavator. The pendulum feeding device comprises a gripper mechanism consisting of a connecting seat (5), a hydraulic cylinder (6) and a gripper (7), wherein a rotary motor (4) is installed on the connecting seat (5) and connected with a universal joint (3), the other end of the universal joint (3) is movably connected with a connecting plate (2), and fixed connection is formed between the other end of the connecting plate (2) and a bucket rod (1) of the hydraulic excavator. The pendulum feeding device is greater in operation, loading and unloading height, realizes the always vertical feeding and discharging of the excavator on the ground with various slopes, can rotate by 360 degrees to adjust feeding and discharging directions, has high efficiency, rapidness and extremely high reliability, and is simple, good in stability and long in service life.

Description

technical field [0001] The invention relates to a pendulum type grabbing device for a hydraulic excavator. Background technique [0002] At present, most of the existing excavator grabbing devices at home and abroad are to keep the grabbing device in a vertical state as much as possible by adjusting the posture of the stick and the boom. However, this operation is troublesome and requires the operator to have rich operating experience. The existing grabbing device does not have a rotating mechanism, and it is necessary to change the body posture of the excavator to adjust the grabbing and unloading directions, which is very troublesome and inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grabbing device that can always load and unload materials vertically and can rotate 360 ​​degrees, so that the excavator can easily and flexibly grab and unload materials. [0004] The present invention solves the ...
