Abstract
The utility model provides a dozer straight tilt blade. The blade comprises a shovel blade, inclined supports, a tilt cylinder, push rods, a lifting tilt cylinder, trunnion bases, a lifting cylinder and an adjusting screw, wherein the front ends of the two push rods are spherically hinged with the shovel blade; the rear ends of the push rods are spherically hinged with the trunnion bases fixed on main racks; the inclined supports are hinged on the outer sides of the push rods and are spherically hinged with the shovel blade; the front of the push rod on one side and the shovel blade are hinged with the tilt cylinder; the rear of the push rod on one side is hinged with the lifting tilt cylinder with the other end hinged with one main rack; the front of the push rod on the other side and the shovel blade are hinged with the adjusting screw; and the rear of the push rod on the other side is hinged with the lifting cylinder with the other end hinged with the main rack. The blade ensures the stress on the shovel blade to be more reasonable and can simultaneously simplify design and manufacture of the front hood and save certain materials and manufacture cost.
Description
Technical field
The utility model belongs to bulldozer equipment technical field, is specifically related to a kind of bulldozer shovel that directly inclines.
Background technology
The tradition bulldozer directly inclines and shovels normally that push rod is installed on the bogie frame, and lift cylinder be installed to before on the hood because perching knife is greatly stressed and complicated, therefore before hood need strengthen.Even can be because of the insufficient strength of preceding hood, the deformation failure of hood before stressed the causing of perching knife.Preceding hood is seemed not too reasonable as force structure.
Summary of the invention
The purpose of the utility model provides a kind of bulldozer shovel that directly inclines, and the problem of solution is to make directly incline shovel push rod and lift cylinder of bulldozer all be installed on the large-sized structural parts more reasonable stress.
The purpose of the utility model realizes as follows: this bulldozer directly inclines to shoveling and comprises perching knife, bearing diagonal, dump ram, push rod, lifting dump ram, trunnion base, lift cylinder, adjustment screw rod; Two push rod front ends and perching knife ball pivot; Putting back-end be fixed on the trunnion base ball pivot on the mainframe; The hinged bearing diagonal in the push rod outside, bearing diagonal and perching knife ball pivot; Anterior and the hinged dump ram of perching knife of one thruster bar, the lifting dump ram that the hinged other end in rear portion and mainframe are hinged; Opposite side push rod anterior and the hinged adjustment screw rod of perching knife, the hinged other end in rear portion and the hinged lift cylinder of mainframe.
The oil-in and the oil-out that promote dump ram respectively have two, a pair of connection perching knife lift line, a pair of connection perching knife inclination pipeline.The control mode of shoveling tilting action of directly inclining has two kinds: a kind of is that the control dump ram is flexible, makes the pair of angled hydraulic fluid port UNICOM that promotes dump ram simultaneously, makes to promote dump ram along with the inclination of perching knife is freely stretched; Another kind is that inclination pipeline control lifting dump ram is flexible, makes the oil inlet and outlet UNICOM of dump ram simultaneously, makes dump ram along with the inclination of perching knife is freely stretched.
The utility model is on traditional bulldozer directly inclines the shovel basis; All be installed to push rod and lift cylinder on the mainframe; In order to realize directly the incline inclination of shovel of bulldozer, i.e. left and right sides push rod action asynchronous promotes the dump ram setting and is respectively applied for two pairs of hydraulic fluid ports that promote and tilt.The control dump ram stretches to make simultaneously and promotes the dump ram servo-actuated, and perhaps control lifting dump ram is flexible makes the dump ram servo-actuated simultaneously, has realized the inclination of directly inclining and shoveling.
The utility model makes the more reasonable stress of perching knife, can simplify manufacturing and designing of preceding hood simultaneously, practices thrift certain material and manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 1; The utility model comprises perching knife 1, bearing diagonal 2, dump ram 3, push rod 4, promotes dump ram 5, trunnion base 6, lift cylinder 7, adjustment screw rod 8; Two push rod 4 front ends and perching knife 1 ball pivot; Push rod 4 rear ends be fixed on trunnion base 6 ball pivots on the mainframe, the hinged bearing diagonal 2 in push rod 4 outsides, bearing diagonal 2 and perching knife 1 ball pivot; One thruster bar, 4 anterior and perching knife 1 hinged dump rams 3, the lifting dump ram 5 that the hinged other end in rear portion and mainframe are hinged; Opposite side push rod 4 anterior and perching knife 1 hinged adjustment screw rods 8, the lift cylinder 7 that the hinged other end in rear portion and mainframe are hinged promotes dump ram 5 and is connected with the mainframe pin with lift cylinder 7, and trunnion base 6 is installed on the mainframe.The oil-in and the oil-out that promote dump ram 5 respectively have two, a pair of connection perching knife lift line, a pair of connection perching knife inclination pipeline.Perching knife 1 promotes when descending, and promotes dump ram 5 and moves simultaneously with lift cylinder 7.When perching knife 1 tilted, control dump ram 3 was flexible, made simultaneously to promote dump ram 5 inclination oil inlet and outlet UNICOMs and servo-actuated; Perhaps control lifting dump ram 5 inclination hydraulic fluid ports make it flexible, make dump ram 3 oil inlet and outlet UNICOMs simultaneously and servo-actuated, thereby make left and right sides push rod action asynchronous, realize that perching knife 1 tilts.
