The utility model discloses a technique aim at provides the mining grab bucket that a single cylinder, weight are lighter, the structure is simpler, efficiency is higher, and this kind of mining grab bucket's reaction rate is faster, and is safer.
Description
Technical field
The utility model relates to drum-type mine car brake, particularly a kind of mining grab bucket.
Background technology
Grab bucket captures the bucket that silt and various bulk freight can open and close.That a kind of folding mainly keeping left right two combination buckets or multiple jaw captures and draws off the suspender of bulk material.Grab bucket can be divided into fluid pressure type to grab bucket by type of drive and mechanical type grab bucket two large classes, and fluid pressure type grab bucket itself is equipped with opening-closing structure, generally drives with hydraulic ram, and the fluid pressure type grab bucket be made up of multiple jaw is also hydraulic jaw.Hydraulic grab Application comparison in hydraulic pressure class specialized equipment is extensive, and as hydraulic excavator, Hydraulic for lifting load tower etc., hydraulic ram is the drive element of grab bucket most critical.Grab bucket is the load-engaging device under hoisting crane, even if so state-of-the-art grab bucket, also be unable to do without hoisting crane and complete independently work.Otherwise advanced person, again large-tonnage ship unloaders also be unable to do without grab bucket and have production efficiency again.
And the hydraulic actuating cylinder of the existing hydraulic grab for relatively fine particle is too much, heavier-weight, structure too complex, such that the fault rate of grabbing bucket is high, reflection slowly.
Utility model content
For the deficiency that above-mentioned mining grab bucket exists, technical purpose of the present utility model is to provide the mining grab bucket that a kind of single oil cylinder, weight are lighter, structure is simpler, efficiency is higher, and the speed of response of this mining grab bucket is faster, safer.
The utility model is achieved through the following technical solutions:
A kind of mining grab bucket, described mining grab bucket comprises: bucket body, support body, the quantity of described bucket body is 2, described bucket body comprises bucket body arm and scraper bowl, described bucket body arm is provided with two pillar holes on next, described bucket body arm is arranged on support body by a pillar, and the top of described bucket body arm is arranged on in-oil cylinder piston rod by b pillar.
Further, the shape of described scraper bowl is semi-barrel shape, and the shovel thing mouth of described scraper bowl establishes irregular sawtooth, is formed and extrude cooperation up and down when the shovel thing mouth of described two scraper bowls closes up.
Further, be provided with bearing in a pillar hole of described bucket body arm and in b pillar hole, a pillar and b pillar are installed in described bearing.
Further, described oil cylinder is double-piston bidirectional hydraulic oil cylinder, is provided with two piston rods and two pistons in described oil cylinder.
Further, the shape of described support body is rectangular channel, and the top of described support body is provided with weighing apparatus boom device.
The beneficial effects of the utility model are:
1, by being provided with two bucket bodies, these two bucket bodies are controlled by double-piston bidirectional hydraulic oil cylinder, such that the weight of grabbing bucket is lighter, structure is more simple, makes the harmony of bucket body stronger during grab bucket work, thus make grab bucket more flexible, and efficiency is higher;
2, by being semi-barrel shape by the shape of scraper bowl, formed when shovel thing mouth closes up and extrude cooperation up and down, instead of direct just head-on collision being closed up, making the capacity of scraper bowl larger, more not easily spill.
3, by being rectangular channel by the shape of support body, compared to columnar support body, making the weight of support body lighter, more easily beam device being installed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 be bucket body, 2 be oil cylinder, 3 be a pillar, 4 be support body, 5 be b pillar, 6 for piston rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Grab bucket that one is as shown in Figure 1 mining, this mining grab bucket comprises: bucket body 1, oil cylinder 2, a pillar 3, support body 4, b pillar 5, piston rod 6, the quantity of described bucket body 1 is 2, described bucket body 1 comprises bucket body arm 1-1 and scraper bowl 1-2, described bucket body arm 1-1 is provided with two pillar holes on next, described bucket body arm 1-1 is arranged on support body 4 by a pillar 3, and the top of described bucket body arm 1-1 is arranged on the piston rod 6 in oil cylinder 2 by b pillar 5;
Wherein, by the quantity of bucket body 1 is set to two, make more conveniently to load more tiny object particle, the scraper bowl 1-2 of bucket body 1 and bucket body arm 1-1 directly can cast and form, the bucket body intensity of casting is high, facilitate batch manufacturing, bucket body arm 1-1 is provided with two pillar holes on next, by that pillar hole below, bucket body is arranged on support body 4, by the top pillar hole of bucket body arm 1-1, bucket body arm 1-1 is arranged on the piston rod 6 in oil cylinder 2, flexible drive two bucket bodies 1 of piston rod 6 close up and are separated, thus realize the object capturing and put down object.
The shape of described scraper bowl 1-2 is semi-barrel shape, and the shovel thing mouth of described scraper bowl 1-2 establishes irregular sawtooth, is formed and extrude cooperation up and down when the shovel thing mouth of described two scraper bowl 1-2 closes up;
Wherein, be semi-barrel shape by the shape of scraper bowl 1-2, shovel thing mouth is formed when closing up and extrudes cooperation up and down, instead of direct just head-on collision is closed up, make the capacity of scraper bowl 1-2 larger, more not easily spill, establish irregular sawtooth at the shovel thing mouth of scraper bowl 1-2, make more easily to close up when capturing object, the object firmer to some shreds.
Be provided with bearing in a pillar hole of described bucket body arm 1-1 and in b pillar hole, a pillar 3 and b pillar 5 are installed in described bearing;
Wherein, by being provided with bearing in a pillar hole He in b pillar hole, the bearing be provided with can make the rotation of bucket body arm 1-1 more flexibly, friction force is less.
Described oil cylinder 2 is double-piston bidirectional hydraulic oil cylinder, is provided with two piston rods 6 and two pistons in described oil cylinder 2;
Wherein, by being double-piston bidirectional hydraulic oil cylinder by oil cylinder 2, be provided with two piston rods 6 and two pistons in oil cylinder 2, these two piston rods 6 control bucket body 1 respectively, such that the structure of grabbing bucket is simpler, weight is lighter, it is more flexible to control.
The shape of described support body 4 is rectangular channel, and the top of described support body 4 is provided with beam device;
Wherein, for the structure of this bucket body 1, support body 4 is set to the structure of rectangular channel, can reduces volume and the weight of support body 4, at the beam device that the top of support body 4 is provided with, conveniently can lift grab bucket, it is inner that support body 4 is located at by oil cylinder 2, can better protect oil cylinder 2.
