Description
Technical field
The utility model relates to.
Background technology
Mainly constitute with the matching used snow-pusher of motor vehicle by pushing snowboard, body cradle and rocker etc.Edge plate of shovel is hinged on the bottom of pushing snowboard, by linkage and spring pushing snowboard is connected with bearing, after edge plate of shovel runs into obstruction, overcomes initial tension of spring and under the effect of linkage, reset after making the pushing snowboard upset, realize the function of crossing obstacle automatically.But it is undesirable that the snow-pusher of said structure exists the obstacle detouring effect, and the impact force that pushing snowboard causes in resetting is bigger, can influence the problems such as application life of pushing snowboard.At the problems referred to above, our company changes pushing snowboard into split-type structural, in the snow pushing process, each pushing snowboard with make the rocker servo-actuated after ground contacts, improve the snow pushing effect.In addition, not only be provided with extension spring between each pushing snowboard and the bearing, but also be provided with the click-on mechanism of clamping pushing snowboard, when the pushing snowboard obstacle detouring, must overcome extension spring pretightning force and click-on mechanism and clamp the masterpiece flip-flop movement, increase the obstacle detouring resistance of pushing snowboard, make it have obstacle climbing ability preferably.But the said structure pushing snowboard has only the snow pushing function, and can not blizzard, therefore when requiring under the occasion of blizzard, need change the snow pushing direction of loader at any time, has increased the complexity of operation.
Summary of the invention
The utility model provides a kind of simple in structure for solving above-mentioned weak point, can distinguish obstacle detouring, but snow pushing or blizzard again can be regulated the automatic obstacle crossing type pushing snowboard of snow pushing width.
The utility model for the technical scheme that solves above-mentioned purpose is: a kind of automatic obstacle crossing type pushing snowboard, it is characterized in that: the movable pushing snowboard of pushing snowboard and hinged its both sides of difference in the middle of comprising, the back of middle pushing snowboard is provided with hinged seat, hinged seat is provided with oil cylinder seat, movable pushing snowboard its underpart that the back is provided with on the oil cylinder seat is hinged with movable edge plate of shovel, the back of movable edge plate of shovel is provided with Connection Block, one end of screw rod is hinged on the Connection Block, the other end of screw rod passes the via hole of movable pushing snowboard top stiffener, and fix with nut, and be provided with cushion pad between stiffener and the nut, also be connected with spring base on screw rod, spring is arranged between stiffener and the spring base.
The utility model adopts the advantage after the technique scheme to be: 1, pushing snowboard of the present utility model is by middle pushing snowboard with movable pushing snowboard is hinged constitutes, by two snow pushing oil cylinder control activity pushing snowboards, therefore can make the movable pushing snowboard of both sides become angle to carry out blizzard with middle pushing snowboard horizontal sliding or with middle pushing snowboard, make things convenient for user's requirement, in the obstacle detouring process, can surmount obstacles with minimum fabric width, improve snow pushing efficient.2, the movable pushing snowboard lower hinge of the utility model has movable edge plate of shovel, and be connected with screw rod between movable edge plate of shovel and the movable pushing snowboard, movable edge plate of shovel is provided the resistance of obstacle detouring by the elastic force of screw rod upper spring, the scope of the flip angle by screw rod control activity edge plate of shovel simultaneously, position limiting structure is very simple, rational in infrastructure, simple, good manufacturability guarantees the snow pushing effect.3, because two snow pushing oil cylinders are controlled two system activity pushing snowboards respectively, can regulate snow pushing or blizzard width at any time according to operating environment.4, because its elastic force of spring on the screw rod is adjustable, so the obstacle detouring resistance of energy maintenance activity pushing snowboard.
