Description
Technical field
The utility model relates to grabbing puies forward field of mechanical technique, the particularly special grab bucket of a kind of Compressible.
Background technology
Grab bucket is 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, fluid pressure type grab bucket itself is equipped with opening-closing structure, general hydraulic jack drives, hydraulic grab Application comparison in hydraulic pressure class special equipment is extensive, as hydraulic crawler excavator, Hydraulic for lifting load tower etc.; And mechanical type grab bucket itself does not configure opening-closing structure, usually driven by rope or connecting rod external force, can be divided into twin rope grab and single rope grab by operating feature, the most frequently used is twin rope grab.
Although existing grabbing arrangement kind is various various; but in actual life, often can see that existing grabbing arrangement captures discarded dilatant such as some foam, polybags etc.; because foam and polybag have certain dilatancy; and the inside of grab bucket captures limited space; inside does not have compressible devices again, thus result in the few and ineffective phenomenon of the disposable crawl amount of grab bucket.Given this, be badly in need of the special grab bucket that a kind of inside of design has a compressible devices and solve this problem.
Utility model content
In order to solve the problem, the utility model provides the special grab bucket of a kind of Compressible, solve existing grabbing arrangement inner space limited and cause the difficult problem that disposable crawl amount is few, there is the many and operating efficiency advantages of higher of good, the disposable crawl amount of compressible performance.
To achieve these goals, the utility model realizes by the following technical solutions: the special grab bucket of a kind of Compressible, comprise bucket body, two collapsible devices, protective cover and bucket tooths, described bucket body is shellfish type structure, the central axis of the upper end edge bucket body of bucket body is symmetrical arranged two and installs hanger, installing hanger by two is arranged on existing crane by the utility model, and the left and right end of bucket body is symmetrically arranged with two openings, two described collapsible devices are along symmetrical two opening parts being arranged on bucket body of central axis of bucket body, collapsible device comprises folded sheet, fixed block, follower link, drive connecting rod, internal threaded column, spherical hinge, hydraulic cylinder and bearing, described folded sheet is sector structure, folded sheet is provided with an oblique recess near one end of opening part, and be connected by hinge between folded sheet and the opening part inwall on bucket body, folded sheet can rotate around hinge under the effect of external force, the foam captured or polybag that are positioned at bucket body inside are compressed, described fixed block is connected by screw with between folded sheet, described follower link is oblique L-type, one end of follower link is welded on the middle part of fixed block through the oblique recess on folded sheet, the situation that oblique recess on folded sheet prevents kinematic link to interfere with folded sheet in motion process, the other end of follower link is connected by bearing pin with drive connecting rod through the opening on bucket body, opening on bucket body had both played the range of movement effect limiting follower link, also the effect supporting follower link in motion process is played, described drive connecting rod is provided with internal threaded column away from one end of follower link, be connected by screw thread between described internal threaded column and the movable end of spherical hinge, be connected by screw thread between described spherical hinge fixed end and the piston rod on hydraulic cylinder, because the direction of motion of hydraulic cylinder is fixed, and the movable end of spherical hinge arbitrarily can rotate along peripheral direction, thus the hydraulic coupling making hydraulic cylinder produce can effectively drive drive connecting rod to move, described hydraulic cylinder bottom is fixedly mounted on bearing, described bearing is oblique triangular shape, and bearing is welded on the outer wall of bucket body, bearing plays effect that is fixing and supporting cylinder, described protective cover is positioned at the outside of collapsible device, and protective cover is welded on the outer wall of bucket body, and protective cover protects collapsible device, prevents from laminating compression apparatus generation impact force in the doubling of motion process crawl thing and affecting the progress of work of the present utility model, the central axis uniform welding of described bucket body front end edge bucket body has row's bucket tooth.During work, first installing hanger by two on bucket body is arranged on existing crane by the utility model, the utility model is started working, existing crane drives bucket body work, bucket body starts once to capture article by bucket tooth, after foam or polybag etc. enter bucket body inside, hydraulic cylinder on two collapsible devices is started working simultaneously, piston rod on hydraulic cylinder drives drive connecting rod to rotate by spherical hinge, drive connecting rod drives follower link to rotate, follower link Foldable plate rotates, folded sheet on two collapsible devices starts the crawl thing compressing bucket body inside simultaneously, when folded sheet moves to vertical bucket body sidewall, two hydraulic cylinders quit work, then existing crane controls the utility model motion again, bucket body starts secondary by bucket tooth and captures article, add disposable crawl amount, improve operating efficiency.
As a kind of optimal technical scheme of the present utility model; described protective cover rear end is hollow mouth; because the piston rod active length of hydraulic cylinder is longer; protective cover rear end is the work that hollow mouth would not stop hydraulic cylinder; and the effect of protection collapsible device is played again in protective cover front end simultaneously, prevent collapsible device in motion process, be subject to capturing the impact force interference of thing.
As a kind of optimal technical scheme of the present utility model, described bucket tooth is long pyramidal structure, and the front end of bucket tooth is provided with fillet, because crawl thing is waste foam or polybag, according to pointed bucket tooth, then in the utility model motion process, waste foam or polybag can be inserted on bucket tooth, bucket tooth of the present utility model is long pyramidal structure and is provided with fillet, limited avoids this problem, improves operating efficiency
As a kind of optimal technical scheme of the present utility model, described bucket tooth is at least five, and the length of bucket body is longer, and required bucket tooth is more, and operating efficiency is higher, and the quantity of bucket tooth can be determined according to usable condition.
The beneficial effects of the utility model are: the utility model compared to existing technology, the crawl thing being positioned at bucket body inside effectively can be compressed in the collapsible device busy process of the inner both sides of bucket body, solve existing grabbing arrangement inner space limited and cause the difficult problem that disposable crawl amount is few, there is the many and operating efficiency advantages of higher of good, the disposable crawl amount of compressible performance.
