Abstract
The invention relates to an excavator bucket and aims to solve the problem of conflict between the excavating efficiency and the land leveling efficiency of an existing excavator bucket. The excavator bucket disclosed by the invention comprises a left side plate, a right side plate and a bucket bottom, wherein a flat plate part is arranged in the front of the bucket bottom, a back plate part is arranged at the back of the bucket bottom, and a circular arc connecting part is arranged in the middle of the bucket bottom; a main knife plate is arranged at the front edge of the flat plate part; at least one longitudinal strip-shaped land leveling rib is arranged on the bottom surface of the bucket bottom in a welding way; the front end of the land leveling rib is butted with the main knife plate, and the rear end of the land leveling rib is lapped on the circular arc connecting part of the bucket bottom; the bottom surface edge of the land leveling rib is a straight line; the shape of the top surface of the land leveling rib is matched with that of the bottom of the bucket bottom, and the top surface of the land leveling rib is attached to the bucket bottom. Through the land leveling rib, the straight surface in the left-right direction is enlarged, and the leveling efficiency is improved; a land leveling rib plate in the excavation direction is protruded downwards and is resistant to soil, the bucket is guided during excavation, the excavation resistance is lower, the land leveling rib plate can be used as a wear-resistant plate, and the bucket is more wear-resistant.
Description
Technical field
The present invention relates to a kind of scraper bowl, particularly relate to a kind of power shovel.
Background technology
Power shovel comprises at the bottom of left plate, right plate and the bucket between left plate and right plate, wherein the struggle against front end at the end has operator plate, the front portion at the bucket end is straight flat part, the front end of flat part is operator plate, the rear end at the bucket end is back, be circular sliding slopes portion between back and flat part, the front end curvature in circular sliding slopes portion is less, and curvature is larger more backward.Existing power shovel is in order to ensure its smoothness excavated, and make the flat part of front end at the bottom of scraper bowl bucket short as much as possible when bucket shape designs, circular sliding slopes portion then extends as far as possible forward.But excavator is as the king of engineering machinery, it is often faced with various working, such as excavator is leveled land effect in addition, by the flat part maintenance level of scraper bowl when excavator is leveled land, then scraper bowl swings, utilize the flat part of front portion at the bottom of scraper bowl bucket to level land, the flat part of bucket front portion, the end is longer, then the efficiency of leveling land is higher.In order to improve the efficiency that excavator is leveled land, the way that prior art is general is that the flat part of front portion at the bottom of bucket is extended back as far as possible, lengthens the planarea that its scraper bowl swings; The consequence done like this has limited the design of bucket type, and bucket type transitionality is deteriorated; Struggle against in the process of the rotating rear end of flat part of front portion, the end of its scraper bowl when excavating can carry out contacting with soil and make the increase of excavating resistance, thus affects its smoothness excavated; Excavating resistance increases, it is not smooth to excavate, and easily affects the efficiency of loading and unloading.
Summary of the invention
The object of the invention is to solve existing power shovel excavate with the efficiency collision problem existed during level land and provide a kind of can ensure that scraper bowl excavates time smoothness, advantage that excavating resistance is little, when can ensure again level land, there is high efficiency power shovel.
The present invention is the technical scheme realizing its object is such: construct a kind of power shovel, comprise left plate, at the bottom of right plate and the bucket between left plate and right plate, the bucket end, comprises anterior flat part, be positioned at the backboard portion at rear portion, circular sliding slopes portion between flat part and backboard portion, the leading edge of flat part is provided with operator plate, the strip level land muscle of at least one longitudinal direction is provided with in the bottom surface welding at the bucket end, the front end of level land muscle is docked with operator plate, rear end is overlapped in the circular sliding slopes portion at the bucket end, the limit, bottom surface of level land muscle is flat line, the top surface shape of level land muscle mate with the bottom shape at the bucket end and is affixed merging with the end of struggling against and welds together.Such level land muscle defines large planarea at scraper bowl left and right directions, and defines little strip at excavation direction; Which increase the planarea of left and right directions, and smooth efficiency is improved greatly; Give prominence to downwards at its strip level land gusset of excavation direction, scraper bowl is fallen into and has resistant function into soil, and level land gusset takies the sub-fraction of whole bucket floor space, so there is the effect to scraper bowl guiding when excavating, and the resistance excavated is less, it can also use as wearing plate, and scraper bowl is more wear-resisting; Level land muscle can be one, also can be two or more, is good with two to six, for parallel interval is arranged between many level land muscle.
In above-mentioned power shovel, the rear end face of level land muscle is the depression end face caved in forward.There is standing shape the rear end of level land gusset relative to the bucket end, and it can play the effect that scraper bowl prizes the unclassified stores such as stone backward.
In above-mentioned power shovel, the bottom at the bucket end is provided with the stiffener of lateral separation welding setting.Front portion due to the end of struggling against has the guide effect of level land muscle, and arranging horizontal stiffener at bucket bottom front interval, the end very can not increase excavating resistance, but the stiffener of transverse direction can strengthen the intensity at the bucket end well.
Compared with prior art, its advantage is in the present invention:
The level land muscle at the bucket end defines large planarea at scraper bowl left and right directions, and defines little strip at excavation direction; Which increase the planarea of left and right directions, and smooth efficiency is improved greatly; Give prominence to downwards at its strip level land gusset of excavation direction, scraper bowl is fallen into and has resistant function into soil, and level land gusset takies the sub-fraction of whole bucket floor space, so there is the effect of guiding to scraper bowl when excavating, and the resistance excavated is less, it can also use as wearing plate, and scraper bowl is more wear-resisting.
