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
The present invention relates to a kind of hydraulic crawler excavator pendulum model material catching apparatus.
Background technology
At present, domestic and international existing excavator material catching apparatus mostly is by adjusting the posture of dipper, swing arm, so that material catching apparatus keeps vertical state as far as possible, but such troublesome poeration needs the operator that more rich operating experience is arranged.Existing material catching apparatus needs to change the excavator base machine posture and adjusts material grasping and discharge direction, so very trouble and inefficiency without rotating mechanism.
Summary of the invention
Technical problem to be solved by this invention provides a kind of material that vertically loads and unloads all the time, and the material catching apparatus of energy 360 degree rotations, and realization excavator easy and flexible is grabbed the material work of unloading.
The present invention addresses the above problem with following technical scheme:
Hydraulic crawler excavator pendulum model material catching apparatus of the present invention, comprise the gripper mechanism that is formed by Connection Block, hydraulic jack and gripper, on its Connection Block rotary motor is installed, rotary motor is connected with universal joint, the other end of universal joint and junction plate are flexibly connected, and the other end and the hydraulic excavator bucket of junction plate form a fixed connection.
Hydraulic crawler excavator pendulum model material catching apparatus of the present invention, described universal joint is comprised of two staggered revolute pairs up and down, and secondary the formation with junction plate of upper driving is flexibly connected, and secondary formation with rotary motor is flexibly connected underdrive.
Hydraulic crawler excavator pendulum model material catching apparatus of the present invention forms a fixed connection by two bearing pins between described junction plate and the hydraulic excavator bucket.
The operation access height of material catching apparatus of the present invention is higher, and has realized excavator all the time vertically material grasping and discharging on various gradients ground, and can 360 degree rotations adjust material grasping and discharge direction, have high efficiency, agility and extremely strong reliability, and simple, good stability, long service life.
Description of drawings
Fig. 1 is the structural representation of material catching apparatus of the present invention.
Fig. 2 is the structural representation of universal joint 3 among Fig. 1.
Fig. 3 is that schematic diagram is looked on the left side of Fig. 2.
Among the figure: hydraulic excavator bucket 1, junction plate 2, universal joint 3, rotary motor 4, Connection Block 5, hydraulic jack 6, gripper 7, upper driving pair 8, underdrive pair 9.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.With reference to Fig. 1, junction plate 2 is fixed on the hydraulic excavator bucket 1 by two bearing pins, avoided material catching apparatus at work swing can bump against excavator boom 1, increased again access height; Universal joint 3 forms by forming staggered upper driving secondary 8 and underdrive pair 9, upper driving secondary 8 forms with junction plate 2 and is flexibly connected, the secondary formation with rotary motor 4 of underdrive is flexibly connected, under action of gravitation, so that material catching apparatus remains vertical posture; The rotary motor 4 of band supporting and swivel coupling function is installed on the Connection Block 5, under the effect of excavator high pressure liquid force feed, can drive Connection Block 5 and realize 360 degree rotations, to satisfy the various loading and unloading postures of material catching apparatus; Connection Block 5, two hydraulic jacks 6 and two grippers 7 form gripper mechanism, two grippers 7 are flexibly connected with the bottom of Connection Block 5, two hydraulic jacks 6 are installed in respectively between the gripper 7 and Connection Block 5 of both sides, hydraulic jack 6 is flexible under the effect of excavator high pressure liquid force feed, driving two grippers 7 rotates around two hinges of Connection Block 5, realize gripper 7 opening and closing, thereby realize material grasping and discharging.
How about the present invention sees Fig. 2 and shown in Figure 3 because the universal joint 3 that adopts is comprised of two staggered revolute pairs, no matter excavator is in the ground of gradient, under action of gravitation, makes material catching apparatus remain vertical state.And adopt the rotary motor 4 of band supporting and swivel coupling function to drive Connection Block 5, so that gripper mechanism is realized 360 degree revolutions, satisfy any loading and unloading posture.
