Description
Technical field
The utility model relates to a kind of snow-pusher, relates in particular to a kind ofly to be and the matching used automatic obstacle crossing type snow-pusher of loader.
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, run into obstruction after, edge plate of shovel overcomes initial tension of spring and under the effect of linkage, make pushing snowboard upset back and automatically reset the function of realization crossing obstacle automatically.But the snow-pusher of said structure exists that the obstacle detouring effect is undesirable, and the impact force that pushing snowboard is caused in resetting is bigger, can influence problems such as pushing snowboard application life.At the problems referred to above, the snow-pusher of our company exploitation is to change 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 snow-pusher has only the snow pushing function, and can not directly carry out 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 pushing snowboard that can make to have obstacle detouring respectively for solving above-mentioned weak point, and the obstacle detouring resistance is big, and the automatic obstacle crossing type snow-pusher of energy snow pushing or blizzard.
The utility model for the technical scheme that solves above-mentioned purpose is: a kind of automatic obstacle crossing type snow-pusher, comprise pushing snowboard, linkage and snow pushing oil cylinder, it is characterized in that: described pushing snowboard by middle pushing snowboard and respectively the movable pushing snowboard of hinged its both sides constitute, the back of middle pushing snowboard is provided with hinged seat, one end of last connecting rod and two lower links is hinged on the upper and lower of hinged seat respectively, and the other end of last connecting rod and two lower links is hinged respectively on the upper connecting base and lower connecting base of link, also be provided with on upper connecting base and the lower connecting base and loader connecting rod and the hinged connecting hole of swing arm, middle pushing snowboard, last connecting rod, lower link and link constitute quadric chain, the spring pull bar that is set with spring is hinged on the link, the spring base that is contained in spring pull bar bottom is hinged on the lower link, spring base is between two lower links, and two snow pushing oil cylinders are hinged on respectively on hinged seat and the movable pushing snowboard.
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 and movable pushing snowboard is hinged forms, and middle pushing snowboard and bindiny mechanism constitute as a whole, two snow pushing oil cylinders are connected between middle pushing snowboard and the two movable pushing snowboards, not only make the movable pushing snowboard and the middle pushing snowboard of both sides carry out horizontal sliding, perhaps make movable pushing snowboard and middle pushing snowboard form certain included angle and carry out blizzard, can satisfy user's requirement, and in the obstacle detouring process, split type pushing snowboard can surmount obstacles with minimum fabric width, improves snow pushing efficient.2, the utility model is connected with the spring pull bar of sleeve spring between link and lower link, when the loading arm lifting, by the spring pull bar connecting rod and lower link and middle pushing snowboard are moved together, the movable pushing snowboard that middle pushing snowboard drives both sides promotes whole pushing snowboard together; And when snow pushing, apply a pressure earthward by the spring on the spring pull bar to pushing snowboard, guarantee the snow pushing effect, in case when middle pushing snowboard runs into obstacle, overcome the spring pressure on the spring pull bar, the quadric chain action, obstacle detouring is raised in the pushing snowboard upset in the middle of making, and after obstacle disappears, by the deadweight of pushing snowboard and the pressure of spring pushing snowboard is automatically reset, reliable operation.3, the utility model swings the spring pull bar owing to be provided with the spring pull bar on linkage between two lower links, so during obstacle detouring, makes pushing snowboard have forward and backward deflection.4, because its elastic force of spring on the spring pull bar is adjustable, the obstacle detouring resistance of pushing snowboard in the middle of therefore keeping.
