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, particularly relate to a kind of bucket of excavator.
Background technology
Excavator is when scraper bowl excacation, and scraper bowl side can be subject to the collision of bulk stone or unclassified stores; If when rigidity is not enough, side seal board will by collision deformation; In order to prevent material to be out of shape the collision of scraper bowl side, at the edge of scraper bowl side and centre, stiffener is set to ensure the rigidity of scraper bowl side at present.Existing scraper bowl is out of shape to prevent scraper bowl from being collided in order to the rigidity strengthening scraper bowl side, its means usually adopted are the external reinforcing plate for cars arranging strip 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 one end is connected with side edge plate 2, the other end point to obliquely bucket the end be connected with external reinforcing plate for car 10.The shortcoming of this structure is that the effect strengthening side plate rigidity only can be played in 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 reinforcement side seal board rigidity for the stiffener on the side seal board of existing bucket and can not strengthen the shortcoming of whole scraper bowl intensity and provide a kind of bucket, the intensity of whole scraper bowl also strengthened by the stiffener on this bucket while strengthening side seal board rigidity.
The present invention for the technical scheme realizing its goal of the invention and provide be such: construct a kind of bucket, comprise base plate and frid, frid is welded on the top of base plate, the hinged otic placode of the hinged installation of scraper bowl is welded with at base plate and frid middle position, at base plate and frid each side from being welded with side seal board, side seal board is welded with side edge plate at the opening part of scraper bowl, every block side seal board is welded with the stiffener that at least one is strip, the lower end of stiffener is connected with 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 of setting like this can strengthen the rigidity of side seal board effectively, prevent it from causing distortion when being collided, operationally simultaneously, from the load hinged otic placode after base plate and frid are delivered to side seal board, stiffener is conducive to load being converged on side edge plate, improves the intensity of scraper bowl.In the present invention as stated above, the upper edge of side seal board is positioned at the side in hinged otic placode horizontal direction, and also namely the upper end of stiffener is positioned at the horizontal direction side of hinged otic placode.
In foregoing invention, stiffener only can comprise upper reinforcing plate, and the lower end of upper reinforcing plate is connected to 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.Or stiffener only includes lower reinforcing plate, the lower end of lower reinforcing plate is connected to 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.Or stiffener comprises upper reinforcing plate and lower reinforcing plate simultaneously, the lower end of upper reinforcing plate is connected to 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 to 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 both less parallel that upper reinforcing plate and lower reinforcing plate have identical trend.And upper reinforcing plate on side seal board can also have stiffener in identical trend with upper reinforcing plate and lower reinforcing plate with welding between lower reinforcing plate, the lower end of middle stiffener and the connection of side edge plate, the upper end of middle stiffener extends to the upper edge of side seal board.
In the present invention as stated above, the bottom of side seal board is also welded with backplate, the upper edge of backplate and the lower of side seal board are along welding, laterally connect with the side weld of base plate lower side under backplate, the front end of backplate is welded with the bottom of side edge plate, and the rear end of backplate extends to side seal board rear portion along the lower edge of side seal board is welded mutually with bottom rear side.
Compared with prior art, tool has the following advantages in the present invention:
The present invention is by after the design to scraper bowl side structure, and stiffener not only can strengthen the rigidity of side seal board, can also improve the intensity of whole scraper bowl; Thus suitably can carry out loss of weight design to bucket configuration, and reach the object improving bucket configuration intensity and reduce cost.
