Abstract
The utility model discloses a variable angle dozer blade structure of a hydraulic excavator, which comprises a support and a dozer blade, wherein the rear end of the support is connected with an underframe of the hydraulic excavator, a cross beam is connected in the middle of the support, a lifting cylinder is connected between the cross beam and the underframe of the hydraulic excavator, the front end of the support is hinged to the rear middle portion of the dozer blade via a hinge mount, and a dozer blade angle changing cylinder is hinged between the rear side of the dozer blade and the support. The variable angle dozer blade structure changes a hinge form between the dozer blade and the support, has functions of changing advancing directions of the dozer blade and excavator leftwards and rightwards during bulldozing operation by aid of the angle changing cylinder which is additionally arranged therein, thereby being capable of bulldozing earth and stones to one side of the advancing direction the hydraulic excavator fast and high-efficiently, increasing operation efficiency, shortening operation period and reducing operation cost.
Description
Technical field
The utility model relates to a kind of variable angle dozer mechanism that is applicable to hydraulic crawler excavator.
Background technology
At present, the dozer equipment that the hydraulic crawler excavator product of domestic and international market is equipped with all is that dozer is fixedlyed connected with the dozer support, and dozer support and excavator underframe are vertical articulated form, and promptly the dozer perching knife is vertical all the time with the excavator direct of travel.In the soil-shifting operation process, the direction of advance of the cubic metre of earth and stone can only be along the direct of travel of hydraulic crawler excavator, as need the cubic metre of earth and stone is poured into the side (the backfill operation after for example hydroelectric line is laid) of excavator direct of travel, then must carries out the advancing of excavator, back operation continuously to adjust the operating position of whole excavator.The hydraulic crawler excavator that this kind is equipped with the fixed angle dozer does not possess the function that changes angle between dozer and the excavator direct of travel in the soil-shifting operation process, as need the cubic metre of earth and stone is shirked ideal position, need repeatedly adjust the operating position of complete machine, operating efficiency is low, duty cycle is long, can not adapt to the requirement of economy, efficient engineering construction.
Summary of the invention
The defective that does not have the angle function for the dozer equipment that overcomes existing hydraulic crawler excavator outfit, the utility model provides a kind of variable angle dozer mechanism of hydraulic crawler excavator, adjust the angle between dozer perching knife and whole the excavator direct of travel about this mechanism's energy, thereby implement more fast and efficiently to bulldoze or shovel is avenged operation.
The technical scheme that its technical problem that solves the utility model adopts is: this dozer mechanism comprises support and dozer, back-end support links to each other with the excavator underframe, be connected with crossbeam in the middle of the support, be connected with hoist cylinder between crossbeam and the excavator underframe, the support front end is hinged with dozer angle oil cylinder by hinged in the middle of pivoting support and otic placode and the dozer back between dozer back and the support.
The utility model is on the basis of original hydraulic crawler excavator dozer structure, being fixedly connected as between change dozer and the dozer support is hinged, and respectively be welded with contiguous block at the rear portion of dozer support and the back of dozer, the angle oil cylinder is installed between the hinge on the contiguous block.As needing the cubic metre of earth and stone is shirked to the left side of excavator direction of advance in the soil-shifting operation process, the angle oil cylinder is overhanging, promotes dozer hinge on the dozer pivoting support and counterclockwise rotates the Φ angle.As need the cubic metre of earth and stone is shirked to the right side of excavator direct of travel, the angle oil cylinder shrinks, and pulling dozer hinge clockwise direction on the dozer pivoting support rotates the Φ angle.
The utility model has changed the articulated form between dozer and the support, increased the angle oil cylinder, make hydraulic crawler excavator in the soil-shifting operation process, have left, change the function of angle between dozer and the excavator direct of travel to the right, can fast and efficiently the cubic metre of earth and stone be shirked a side to the hydraulic crawler excavator direct of travel, improved operating efficiency, shorten duty cycle, reduced the work production cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the left-leaning status architecture schematic diagram of the utility model dozer.
Fig. 2 is the utility model dozer Right deviation status architecture schematic diagram.
1. left socles among the figure, 2. excavator walking device, 3. crossbeam, 4. pivoting support, 5. dozer, 6. otic placode, 7. first contiguous block, 8. angle oil cylinder, 9. hoist cylinder, 10. right support, 11. second contiguous blocks, 12. excavator underframe.
The specific embodiment
In Fig. 1, support comprises left socle 1 and right support 10, left socle 1 links to each other with excavator underframe 12 with right support 10 rear ends, be connected with crossbeam 3 in the middle of left socle 1 and the right support 10, be connected with hoist cylinder 9 between crossbeam 3 and the excavator underframe 12, left socle 1 and right support 10 front ends are middle hinged with dozer 5 back by pivoting support 4 and otic placode 6, are hinged with dozer angle oil cylinder 8 between dozer 5 back and the right support 10.
At the left-leaning job state of dozer shown in Figure 1, hoist cylinder 9 actions, plunger extends the appropriate location outward, makes dozer 5 and ground keep the operation distance.8 actions of angle oil cylinder, plunger is stretched entirely, promotes dozer 5 hinge on pivoting support 4 and counterclockwise rotates, and makes dozer 5 become the Φ angle with excavator walking device 2 leading edges.
At dozer Right deviation job state shown in Figure 2, hoist cylinder 9 actions, plunger extends the appropriate location outward, makes dozer 5 and ground keep the operation distance.8 actions of angle oil cylinder, plunger is full reduced, and the hinge clockwise direction of pulling dozer 5 on pivoting support 4 rotates, and makes dozer 5 become the Φ angle with excavator walking device 2 leading edges.
Claims (1)
