Abstract
The invention discloses a loader bucket, and relates to the technical field of loader buckets. The loader bucket comprises a loader bucket body and a plurality of bucket teeth installed at the front end of the bucket body. The bucket teeth are a plurality of movable knife plates spliced side by side, and the movable knife plates are connected with the bucket body through fasteners. Each movable knife plate is provided with a connection portion, and one or more sharp tooth portions arranged at one end of the corresponding connection portion and connected with the corresponding connection portion into a whole. The free end of each sharp tooth portion is a sharp-corner-shaped tooth top, and each sharp tooth portion extends obliquely towards the two sides of the corresponding connection portion from the tooth top to form two first oblique edges. Compared with the prior art, due to the fact that the work portions of the movable knife plates can be adjusted, the loader bucket has dual effects, thereby being capable of better adapting to the working conditions of shoveling and loading cold steel slag and greatly improving the working efficiency.
Description
Technical field
The present invention relates to scraper bowl technical field, especially a kind of for shoveling the loading shovel that fills cold slag.
Background technology
In iron and steel manufacturing, in steel smelting procedure, produce a large amount of slags, the cold slag that slag forms after cooling, needs further to process such as scraper, pulverizing etc., and slag after treatment can be used for paving the way, doing constructional materials etc.Wheel loader is more and more applied to the processing procedure of cold slag as a kind of efficient running device.
Slag after coming out of the stove, through water water cooling and air cooling after, form cold slag.Cold slag is that a kind of hardness is high, fragility is large, with the caking shape object of a large amount of pores.Existing loading shovel comprises scraper bowl body and is installed on multiple bucket tooths of described scraper bowl body front end, between bucket tooth, be separated with each other a segment distance, and the working position of bucket tooth is thick large, fill cold slag if adopt this loading shovel to shovel, its bucket tooth type is not suitable with the material feature of cold slag, tends to cause shoveling into resistance excessive, makes the low and scraper bowl quick abrasion of shovel dress efficiency, tyre slip, transmission part life is low etc., finally causes user's working service loader high cost.
Summary of the invention
The object of this invention is to provide a kind of loading shovel, this scraper bowl can solve shovel before cold slag is pulverized, and to enter resistance large, and shovel fills inefficient problem.
In order to address the above problem, the technical solution used in the present invention is: this loading shovel comprises scraper bowl body and is installed on multiple bucket tooths of described scraper bowl body front end, described multiple bucket tooth is the multiple movable knife plate splicing side by side, and described movable knife plate is connected with described scraper bowl body by securing member; Described movable knife plate has a junction and is at least arranged at the pointed tooth portion of described connecting portion one end, described pointed tooth portion and the link of described connecting portion are integrated, the crown that the free end of described pointed tooth portion is tip-angled shape, described pointed tooth portion tilts to extend to form two section of first oblique sword by crown to the both sides of described connecting portion.
In the technical scheme of above-mentioned loading shovel, technical scheme can also be more specifically: at least one side in described pointed tooth portion is provided with the second oblique sword being connected with the described first oblique sword, and the angle of the described second oblique sword and the described first oblique sword is 135 °～165 °.
Further, the described second oblique sword is connected with the side of described connecting portion by arc section.
Further, described two section of first oblique sword is symmetrical set, and the angle between described two section of first oblique sword is 45 °～90 °.
Further, described movable knife plate has with described connecting portion and links the flat tooth portion being integrated, and the end of described flat tooth portion is flat sword, and described flat tooth portion and described pointed tooth part are located at the two ends of described connecting portion.
Further, described flat tooth portion has the oblique surface that is connected in described flat sword place and described connecting portion plane.
On the connecting portion of described movable knife plate, offer the through hole that installs described securing member, described securing member is bolt, and the two ends of described through hole are provided with counterbore.
Further, described movable knife plate is dull and stereotyped.
Further, the side of the connecting portion of adjacent described movable knife plate has the setting-in position of mutual engaging.
Further, described setting-in position be described connecting portion side stretch out the convex arc section of protruding and with the concave arc mouth of described convex arc section tabling.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the two ends of movable knife plate design pointed tooth portion peace tooth portion, capable of regulating commutation is used, and to adapt to the material feature of the cold slag under different conditions, realizes " a pipeful of dual-purpose "; Pointed tooth portion can effectively reduce the insertion resistance of loading shovel, promotes the ability of peeling off material simultaneously, thereby obviously improves shovel dress efficiency; When flat tooth portion is positioned at shovel dress station, can effectively increase Bucket capacity.
2, adopt the movable knife plate of splicing side by side, make in shovel process of assembling, stressed mutual transmission between each movable knife plate, cancel each other, thus the connection reliability of raising activity knife plate and scraper bowl body.
3, two of pointed tooth portion angles are that the first oblique sword of 45 °～90 ° can make movable blade plate be easy to shovel into slag, the crackle of slag of making to lump constantly expands, and and angle between the first oblique sword be the second oblique sword of 135 °～165 ° and can further accelerate the expansion rate of slag crackle, slag after connecting the arc section of the second oblique sword and being conducive to peel off, to scraper bowl internal flow, shovels process of assembling more laborsaving, more efficient.
4, the oblique surface of flat tooth portion contributes to reduce scraper bowl and inserts resistance.
5, offer at the connecting portion of movable knife plate the counterbore that installs bolt, can make the bolt head after set bolt is installed not exceed movable blade board plane, thereby avoid bolt head in scraper bowl shovel process of assembling to be rubbed, flat movable knife plate also contributes to reduce scraper bowl and inserts resistance.
6, setting-in position is designed to convex arc section and concave arc mouth, is conducive to reduce stress.
