Abstract
The invention relates to a digging bucket aiming to overcome the defect that reinforcing plates on side closure plates of an existing digging bucket can only reinforce rigidity of the side closure plates but cannot reinforce strength of the whole bucket. The digging bucket comprises a bottom plate and a trough plate, the trough plate is welded at the top of the bottom plate, a lug plate is welded at the middle position of the bottom plate and the trough plate, side closure plates are welded on the left side and the right side of each of the bottom plate and the trough plate respectively, a side blade plate is welded at the position, at an opening of the bucket, of the side closure plates, at least one strip reinforcing plate is welded on each side closure plate, the lower end of each reinforcing plate is connected with the side blade plate, and the upper end of each reinforcing plate is inclined to the top of the bottom plate and extends to the upper edge of the corresponding side closure plate. The reinforcing plates in the arrangement can reinforce rigidity of the side closure plates effectively and prevent the side closure plates from deformation during collision, load on the hinge lug plate is transmitted to the side closure plates via the top of the bottom plate and the trough plate during working, the reinforcing plates are beneficial to load collection on the side blade plate, and strength of the whole bucket is improved.
Description
Technical field
The present invention relates to a kind of scraper bowl, relate in particular to the bucket that a kind of excavator is used.
Background technology
Excavator is when the scraper bowl excacation, and the scraper bowl side can be subject to the collision of bulk stone or unclassified stores; If when rigidity was not enough, side seal board will be by collision deformation; In order to prevent that material is out of shape the collision of scraper bowl side, at present at the edge of scraper bowl side and middle the rigidity that stiffener guarantees the scraper bowl side is set.Existing scraper bowl is out of shape to prevent scraper bowl from being collided for the rigidity of strengthening the scraper bowl side, its means that usually adopt are that the external reinforcing plate for car of strip is set in the welding of the outside of side seal board, as shown in Figure 1, external reinforcing plate for car 10 and side edge plate 2 form the reinforcement structure of a closed ring, and an interior stiffener 11 is set in side seal board 6 again, interior stiffener 11 1 ends are connected with side edge plate 2, are connected with external reinforcing plate for car 10 at the bottom of the oblique lower sensing bucket of the other end.The shortcoming of this structure is that the effect of strengthening the side plate rigidity only can be played in the scraper bowl side, and little to the intensity effect of whole scraper bowl, and sheet material can not get adequately and reasonably utilizing.
Summary of the invention
The object of the invention is to only can play for the stiffener on the side seal board of existing bucket and strengthen the side seal board rigidity and can not strengthen the shortcoming of whole scraper bowl intensity and a kind of bucket is provided, the stiffener on this bucket is also strengthened the intensity of whole scraper bowl when strengthening the side seal board rigidity.
The present invention is for realizing that the technical scheme that its goal of the invention provides is such: construct a kind of bucket, comprise base plate and frid, frid is welded on the top of base plate, be welded with the hinged otic placode of the hinged installation use of scraper bowl at base plate and place, frid centre position, base plate and frid each side from being welded with side seal board, side seal board is welded with the side edge plate at the opening part of scraper bowl, be welded with at least one stiffener that is strip on every side seal board, the lower end of stiffener is connected with the side edge plate, toe board panel top, upper end and extend to the upper edge of side seal board.In the present invention, the stiffener that so arranges can be strengthened the rigidity of side seal board effectively, prevent that it from causing distortion when being collided, simultaneously when work, load from the hinged otic placode is after base plate and frid are delivered to side seal board, stiffener is conducive to load is converged on the side edge plate, improves the intensity of scraper bowl.In foregoing invention, the upper edge of side seal board is positioned at the side on hinged otic placode horizontal direction, is also the horizontal direction side that the upper end of stiffener is positioned at hinged otic placode.
In foregoing invention, stiffener can only comprise upper reinforcing plate, and the lower end of upper reinforcing plate is connected in the middle part of side edge plate, and the upper end of upper reinforcing plate is positioned at the rear junction of frid and base plate.Perhaps stiffener only includes lower reinforcing plate, and the lower end of lower reinforcing plate is connected in the bottom of side edge plate, and the upper end of lower reinforcing plate is positioned at the horizontal side of hinged otic placode end.Perhaps stiffener comprises upper reinforcing plate and lower reinforcing plate simultaneously, the lower end of upper reinforcing plate is connected in the middle part of side edge plate, the upper end of upper reinforcing plate is positioned at the rear junction of frid and base plate, the lower end of lower reinforcing plate is connected in the bottom of side edge plate, the upper end of lower reinforcing plate is positioned at the horizontal side of hinged otic placode end, and it is also that both are approximate parallel that upper reinforcing plate has identical trend with lower reinforcing plate.And the middle stiffener that can also have identical trend at welding between the upper reinforcing plate on side seal board and lower reinforcing plate and upper reinforcing plate and lower reinforcing plate, the lower end of middle stiffener is connected with the side edge plate, and the upper end of middle stiffener extends to the upper edge of side seal board.
In foregoing invention, the bottom of side seal board also is welded with backplate, the upper edge of backplate is lower to welding with side seal board, the lower of backplate connects along side and the side weld of base plate lower side, weld mutually with base plate rear portion side at the welding of the bottom of the front end of backplate and side edge plate, the rear end of backplate extend to side seal board along the lower edge of side seal board rear portion.
The present invention compared with prior art has following advantage:
The present invention is by after the design to the scraper bowl side structure, and stiffener not only can be strengthened the rigidity of side seal board, can also improve the intensity of whole scraper bowl; Thereby can suitably carry out the loss of weight design to the scraper bowl structure, and reach the purpose that improves scraper bowl structural strength and Cost reduction.
