Description
Technical field
The utility model relates to a kind of bulldozer, relates in particular to a kind of bulldozer Multifunctional scraper knife.
Background technology
Perching knife is one of vitals of bulldozer, is bearing the major part work of bulldozer.Existing bulldozer perching knife accommodation is little, soil-shifting efficiency is low, and the technical problem of existence is as follows: 1, compliance is little, can not change the perching knife amount of capacity according to the proportion situation of operating mode material, causes the dozing Efficiency Decreasing; 2, affected by operating environment larger, can't change the perching knife capacity in narrow and small working space, make bulldozer operation be subject to the environment limitation larger, practicality reduces; 3, function singleness, can not change the perching knife type according to job requirements, causes the bulldozer range of application to reduce.
The utility model content
Technical problem to be solved in the utility model is: a kind of bulldozer Multifunctional scraper knife is provided, solve perching knife and can't change according to features the problem of perching knife capacity, type, can be according to the different work requirement, use different perching knives, effectively improved the bulldozer practicality, realize the automatic adjustment of perching knife capacity in small space, the flexibility that has effectively improved bulldozer operation.
The technical scheme that the problem that the utility model is the above-mentioned proposition of solution adopts is:
A kind of bulldozer Multifunctional scraper knife, comprise left perching knife 1, right perching knife 2, middle perching knife 3, left shovel 4, right shovel 5, limiting plate 6, fixed head 7, swivel plate 8, hydraulic cylinder 9, bearing A10 and bearing B11, perching knife 3 inside in the middle of left perching knife 1 stretches into respectively with right perching knife 2 one ends, middle perching knife 3 two ends, back respectively are welded with bearing A10, bearing B11 is welded respectively in left perching knife 1 and right perching knife 2 back, bearing A10 is connected with bearing B11 by hydraulic cylinder 9, left perching knife 1 is connected by limiting plate 6 and left shovel 4, right perching knife 2 is connected by limiting plate 6 and right shovel 5, the right-hand member of the left end of left perching knife 1 and right perching knife 2 is welded with respectively fixed head 7, the left end of the right-hand member of left shovel 4 and right shovel 5 is welded with respectively swivel plate 8, fixed head 7 is connected with swivel plate 8.
Described left shovel 1 and right shovel 2 is U-shaped shovel head.
Described fixed head 7 is connected with swivel plate 8 with rotary pin shaft 13 by fixed pin shaft 12.
The beneficial effects of the utility model are: 1, can adjust in time the perching knife capacity according to the operating mode material, effectively improve the bulldozer operating efficiency, such as to carry out ore etc. great during than heavy work, control hydraulic jack, the left and right perching knife is shunk, reduce the perching knife capacity, carrying out, sandy soil etc. are little during than heavy work, reduce the hydraulic cylinder piston stroke, the left and right perching knife is stretched, increase the perching knife capacity to increase work efficiency; 2, realize the conversion between straight type shovel and U-shaped shovel, can use different perching knives according to the different work requirement, effectively improved the bulldozer practicality; 3, adopt hydraulic-driven to change the perching knife capacity, realize the automatic adjustment of perching knife capacity in small space, the flexibility that has effectively improved bulldozer operation.
