Abstract
The utility model relates to a kind of multi-functional grabbing excavator bucket, comprise the holder for being connected with the working arm of engineering truck, the bucket be connected on described holder, be hinged on described bucket and coordinate with described bucket can the grab bucket of folding, also include the hydraulic jack driving described grab bucket folding and the fluid pressure drive device driving described hydraulic jack, described hydraulic jack is arranged on described bucket.The utility model is arranged on bucket by hydraulic jack, and when needs digging operation, hydraulic jack extends, and enough large angle is opened in grab bucket, then grabs bucket and do not hinder excacation completely; When needs capture operation, hydraulic jack shrinks, and completes crawl operation, easy to operate, meets the needs of production practices well.
Description
Technical field
The utility model relates to engineering mechanical device field, particularly the multi-functional grabbing excavator bucket of a kind of excavator.
Background technology
At present, in stone material job site, digging equipment that is husky and that grab stone is all independently working, that is, when grabbing stone, excavator can only use special grab bucket to carry out operation, and in time excavating the small particles material such as sand or handstone, bucket will be replaced with and carry out operation, or prepare an engineering equipment job in addition, both wasted equipment and manpower, and also occupied larger construction space.
The one that patent CN200920021673.X mentions novel quick change combined multi-functional bucket, although also can realize grabbing digging function, there are the following problems for this patented technology:
1, because its auxiliary grab bucket needs to carry out grasping movement by the hydraulic means on engineering truck working arm, therefore need to transform existing engineering truck working arm, can use after installing fluid pressure drive device additional.Engineering truck after repacking, is merely able to use this grab bucket, and cannot changes bucket or the grab bucket of other functions.If need to change other forms of grab bucket, bucket, quartering hammer etc., with regard to needing, the fluid pressure drive device installed extra on journey car working arm being carried out dismounting, wasting time and energy.
2, the shape corner angle due to stone are different, stone will be picked up by bucket, need to adjust different angles, otherwise the stone picked up easily comes off, in this case the method solved, one is the parking stall adjusting engineering truck, and some stone fields are owing to limiting by execution conditions, and engineering truck possibly cannot move; Two is the positions adjusting this stone, no matter takes which kind of measure, all greatly can affect operating efficiency.
3, this bucket is not owing to having biting teeth in its occlusion place, when capturing ratchel, because occlusion dynamics is inadequate, stone very easily can be caused to drop, cause security incident.
Therefore, need to provide one to meet and grab, dig two kinds of operating modes constructions, the bucket of highly effective and safe again.
Utility model content
For prior art above shortcomings, the utility model proposes a kind of multi-functional grabbing excavator bucket, this multi-functional grabbing excavator bucket can meet the construction of grabbing, digging two kinds of operating modes.
The utility model realizes like this; A kind of multi-functional grabbing excavator bucket, comprise the holder for being connected with the working arm of engineering truck, the bucket be connected on described holder, be hinged on described bucket and coordinate with described bucket carry out material crawl can the grab bucket of folding, also include for driving described grab bucket carry out the hydraulic jack of opening and closing movement and drive the fluid pressure drive device of described hydraulic jack, described hydraulic jack is arranged on described bucket.
The slew gear that described bucket and grab bucket level can be made to rotate freely is provided with between described bucket and described holder.
Described slew gear is connected with described fluid pressure drive device.
The gripping surface of described bucket and described grab bucket is provided with the biting teeth of working in coordination.
The utility model, by grabbing bucket active link on bucket, by arranging hydraulic jack to drive grab bucket folding and folding size on bucket, avoids the working arm of improvement project car, and can meet crawl and digging operation simultaneously, improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of multi-functional grabbing excavator bucket of the utility model structure diagram when capturing operation;
Fig. 2 is the utility model structure diagram when digging operation;
In figure: 1, holder; 2, bucket; 3, grab bucket; 4, hydraulic jack; 5, fluid pressure drive device; 6, slew gear; 7, biting teeth.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 1 ~ 2, a kind of multi-functional grabbing excavator bucket, comprise the holder 1 for being connected with the working arm of engineering truck, be arranged on the bucket 2 on holder 1, this bucket 2 is hinged with grab bucket 3, for driving the hydraulic jack 4 of described grab bucket 3 folding, this hydraulic jack 4 is arranged on bucket 2, this hydraulic jack 4 piston end is connected with grab bucket 3, this hydraulic jack 4 is connected with fluid pressure drive device 5, stretching by described fluid pressure drive device 5 hydraulic control oil cylinder 4, thus the folding controlled between bucket 2 and grab bucket 3 and folding angular dimension, to complete crawl or digging operation.
The utility model is arranged on bucket by hydraulic jack, under fluid pressure drive device 5 controls, controls the size of grab bucket 3 folding and folding angle by stretching, when needs digging operation, hydraulic jack extends, and enough large angle is opened in grab bucket, then grabs bucket and do not hinder excacation completely; When needs capture operation, hydraulic jack shrinks, and completes crawl operation.
Further, be provided with slew gear 6 between described bucket 2 and holder 1, this slew gear 6 can provide power by fluid pressure drive device 5, bucket 2 and grab bucket 3 can be rotated relative to holder 1 and carry out 360 degree of rotations, to adapt to the material requirement capturing different profile.
Further, the gripping surface of described bucket 2 and grab bucket 3 is provided with the biting teeth 7 matched, can when performing crawl operation, and increasing friction force, prevents material from coming off.
The utility model by arranging slew gear between bucket and holder, enabling the relative holder level of bucket rotate freely 360 degree, like this when capturing difform material, not needing adjustment engineering truck or material, and only need adjustment grab bucket orientation, simple and convenient.
In addition, this utility model, by arranging the biting teeth of working in coordination on bucket and grab bucket, like this when capturing larger material, just can provide enough snap-in forces, preventing material from coming off, improve safety.
Described on end, the utility model can replace two equipment, and can complete the ability to work that two equipment possess, and it is simple to have structure, easy to operate feature.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
