Abstract
The utility model relates to a grab bucket of a hydraulic excavator. The grab bucket of the hydraulic excavator comprises two clamshell buckets (1), a fixing frame (2), two connecting rods (3), a connecting shaft (4), a telescopic oil cylinder (5) and accessory parts of the telescopic oil cylinder (5). One end of the fixing frame is connected with a bucket rod of the hydraulic excavator, and the other end of the fixing frame is respectively connected with a mounting base of the two clamshell buckets. One ends of the two connecting rods are respectively connected with the mounting base of the two clamshell buckets, and the other ends of the two connecting rods are connected with the two ends of the connecting shaft. The root part of the telescopic oil cylinder is fixed to the fixing frame, and the head part of the telescopic oil cylinder is connected with the portion, in the middle of the connecting shaft, of the mounting base. All hinged points are respectively provided with a bush and a lubricating grease filling point. The grab bucket swings vertically or front and back through self gravity to adapt to loading and unloading of materials, the action of the equipment is achieved through a four-link mechanism, the grab bucket is simple and reliable, and work is carried out ingeniously through a large cavity of the oil cylinder.
Description
Technical field
The utility model relates to a kind of hydraulic crawler excavator grab bucket.
Background technology
Along with the development of engineering construction, user is more and more higher to the requirement of the multi-functional and attachment device of excavator, and programming is more and more faster, and working condition is also more and more severe.For excavation machinery, common bucket can not meet the operation that workload is large, operating mode is severe.For meet user to the demand of equipment and equipment the compliance to operating mode, improve the multifunctionality of excavator, designed and developed the grab bucket of a handling that are applicable to bulk material, channel cleanout, excavation moulding groove.
Summary of the invention
The purpose of this utility model is to provide the grab bucket of a kind of hydraulic crawler excavator, has the engineerings such as handling that efficient work, the feature such as simple to operate be mainly used in bulk material, channel cleanout, excavation moulding groove.
Grab bucket comprises 2 shellfish type buckets (1), 1 fixed mount (2), 2 connecting rods (3), 1 connecting shaft (4), 1 telescopic oil cylinder (5) and accessory thereof, wherein, fixed mount one end is connected with hydraulic excavator bucket, and the other end is connected with the mount pad of 2 shellfish type buckets respectively; One end of 2 connecting rods is connected with the mount pad of 2 shellfish type buckets respectively, and the other end of 2 connecting rods is connected with the two ends of connecting shaft; The root of telescopic oil cylinder is fixed on fixed mount, and head is connected with the mount pad in the middle of connecting shaft; Each hinge design lining and grease adding point, can guarantee that hinge is flexibly movable.
This grab bucket utilizes the vertical and swing of deadweight to adapt to the handling of material, with four-bar mechanism, realize the action of equipment, simple and reliable, realizing cleverly and utilizing the large chamber of oil cylinder is that maximum digging force carries out work, and the folding that connecting rod, connecting shaft, telescopic oil cylinder are controlled shellfish type bucket captures and draw off bulk material.The front edge board of bucket designs according to actual condition, and cutting blade angle remains in (150 ~ 450) scope in the course of the work, effectively reduces excavating resistance, maximum performance operating efficiency.The basic structure of grab bucket adopts Q235, and vitals adopts Q345, and the front edge plate of bucket and side edge plate adopt NM400 wear-resisting steel plate, improves abrasion resistance and the intensity of digging element.This grab bucket hydraulic system adopts the broken oil circuit of hydraulic crawler excavator, while being that common bucket, destroyer etc. exchange, only needs to change fluid pressure line (6), simple and fast.This grab bucket has the engineerings such as handling that efficient work, the feature such as simple to operate be mainly used in bulk material, channel cleanout, excavation moulding groove.

The specific embodiment
Grab bucket realizes work with four-bar mechanism, simple and reliable.Grab bucket comprises 2 shellfish type buckets (1), 1 fixed mount (2), 2 connecting rods (3), 1 connecting shaft (4), 1 telescopic oil cylinder (5) and accessory thereof, wherein, fixed mount one end is connected with hydraulic excavator bucket, and the other end is connected with the mount pad of 2 shellfish type buckets respectively; One end of 2 connecting rods is connected with the mount pad of 2 shellfish type buckets respectively, and the other end of 2 connecting rods is connected with the two ends of connecting shaft; The root of telescopic oil cylinder is fixed on fixed mount, and head is connected with the mount pad in the middle of connecting shaft; Each hinge design lining and grease adding point, can guarantee that hinge is flexibly movable.
Utilize the broken oil circuit of excavator to telescopic oil cylinder fuel feeding, by oil cylinder, provide power, when cylinder stretches, grab bucket is closed, realizes the crawl of material; When oil cylinder shrinks, grab bucket is opened, and realizes the unloading of material.
