Abstract

The utility model relates to a big grab-bucket arranged on the arm of a digging machine, which can clamp huge stones and optionally put the huge stones. The huge stones can be rapidly and safely put in the construction of park landscaping, and the acquisition of stones is convenient during walking among mountains and valleys. The utility model has the advantages of high work efficiency, low cost, high effectiveness, and safe usage.

Description

Improved rotary big grab-bucket

The utility model is a kind of big grab bucket, refers in particular to a kind of rotating grab bucket that can be assemblied on the excavator.

At present, in engineering such as beautify the environment, scape is made in gardens, often need to gather, carry and put the construction of megalith, traditional mode is with crane operation, with wire rope binding lifting, and is different because of megalith, is difficult for binding firmly, poor stability during lifting, when putting moulding, operate also dumbly, make this type of construction efficiency very low.

The purpose of this utility model provides a kind of rotary big grab bucket, and it not only can be picked up the random rotation of megalith and put, and cooperates the excavator of the complex-terrain of can walking to quarry in the open air.

The purpose of this utility model is achieved in that having establishes a hydraulic motor on the holder of engagement plate, the rotating disc of fluid motor-driven and its engagement, and rotating disc is connected with pedestal with axle, and pedestal is adorned four lever arms, and the arm end is established jaw.Extension and contraction control lever arm and jaw folding with four hydraulic actuator piston rods, engagement plate is loaded on the digger arm, the hydraulic oil pipe of hydraulic motor is connected to a road binders pipe of excavator, and the hydraulic oil pipe tandem of four hydraulic actuators is connected to another road binders pipe to house steward.Because excavator is suitable for the complex-terrain of walking, hydraulic pressure jaw chucking power is rotatable greatly again, can be advantageously used in the operation of putting that open-air quarrying lifts, scape is made in gardens.

Owing to adopt such scheme, make collection, carry and put this time-consuming unsafe again construction of megalith quick and safe that becomes, can from heavy manual labor, free the constructor, but the reduction of erection time is reduced construction cost.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a side view of the present utility model.

Fig. 3 is a top plane view of the present utility model.

Fig. 4 Fig. 5 is that the utility model is installed in the excavator schematic diagram.

Among the figure: 10 holders, 11 engagement plates, 20 hydraulic motors, 30 rotating discs, 40 pedestals, 50 hydraulic actuators, 51 hydraulic oil pipes, 52 hydraulic oil pipes, 53 piston rods, 60 lever arms, 61 jaws, 62 jaw teeth, 70 digger arms, 80,90 hydraulic oil pipe tandem house stewards

At Fig. 1, among Fig. 2, establish two engagement plates 11 that are connected usefulness with excavator on the holder 10, also establish the hydraulic motor 20 that a usefulness hydraulic oil drives on the holder 10, rotating disc 30 cooperates by being loaded on holder 10 bottoms with axle, there are gear and hydraulic motor engagement in inside, be subjected to hydraulic motor 20 to drive forward and reverse rotation, pedestal 40 is connected rotating disc 30 belows, a left side, two groups of totally 4 hydraulic actuators 50 are respectively established on the right side, two groups of totally 4 lever arms 60 are established in the below, the piston rod 53 of hydraulic actuator connects with axle with lever arm 60, extension and contraction control lever arm 60 foldings of piston rod 53, and jaw 61 is established in lever arm 60 lower ends, the clamping face of jaw 61 is established jaw teeth 62.

The hydraulic oil pipe tandem of 4 lever arms shown in Figure 3 is to house

steward

80,90, and each jaw 61 is stressed even, solid and reliable in the time of can making the clamping megalith.

Among Fig. 4, Fig. 5, engagement plate 11 is by arm 10 front ends that are loaded on excavator, hydraulic oil pipe is connected to the hydraulic system of excavator, operating personnel only need to operate in driving cabin, just can pick up megalith, rotate and put, because the cross-country walk performance of excavator is good, the hill path of can walking easily, that complex-terrains such as riverbed, present embodiment are used is UH20 type excavator (bucket 2m ³Can pick up 30 tons megalith when volume) operating, operation has fast and safely reduced manpower, and time cost has good economic benefits.

Claims

1, the rotary big grab bucket of a kind of modified, it is characterized in that: establish two engagement plate and hydraulic motors that connect digger arm on the holder, holder connects a rotating disc with axle down, rotating disc inside is subjected to its transmission with the gears engaged of gear and hydraulic motor, can forward and reversely rotate, connect pedestal under the rotating disc, two groups of totally 4 hydraulic actuators and two groups totally 4 lever arms are adorned in the pedestal left and right sides, jaw is established in the lever arm lower end, the clamping face of jaw is established jaw teeth, the piston rod of hydraulic actuator links to each other with lever arm with axle, and by the folding of piston rod extension and contraction control jaw, the tandem of 4 hydraulic actuator hydraulic oil pipes is connected to the hydraulic oil pipe of excavator to house steward, and the hydraulic oil pipe of hydraulic motor is connected to another road hydraulic oil pipe of excavator.
