Abstract
The utility model relates to an automatic height-adjustable device for a straw and stalk machine, the top of the straw and stalk machine is hinged with a frame through a connecting arm of the straw and stalk machine. The utility model comprises a vertically arranged regulating lever whose middle part is hinged with the driving wheel axle of a vehicle, and the regulating lever can rotate along the surface that is vertical to the driving wheel axle surface. The top of the rotatable regulating lever is hinged with the top of a flexible oil cylinder, and the piston rod outer end of the flexible oil cylinder is hinged with the middle-lower part of the straw and stalk machine. The bottom of the rotatable regulating lever is hinged with the top of a roller handspike. A trolley altitude controller which can adjust the corner dimension is arranged between the rotatable regulating lever and the roller handspike. The bottom of the roller handspike is arranged with a roller. The utility model is simple in structure, practical, low in manufacturing cost, and can fully realize an automatic regulation towards the height of the straw and stalk machine, which is convenient for the promotion and the application.
Description
Technical field
The utility model relates to a kind of stalk machine and regulates the height device automatically.
Background technology
The stalk machine can't be adjusted height when in use automatically at present, when the gradient of running into upward slope surpasses 10%, the operator can obviously observe the gradient and manually lift the stalk machine then, prevent that forward position, stalk machine bottom from being stopped by the gradient, but when the gradient hour or when subtle, the stalk machine is easy to be gone up a slope stop.This situation can occur equally in descending, it is too high to make the stalk seat in the plane put.This structure influence stalk machine operation causes operating efficiency to descend.
The utility model content
The utility model purpose is to provide a kind of stalk machine easy to use to regulate the height device automatically.
To achieve these goals, the utility model adopts following technical scheme: the stalk machine is regulated the height device automatically, stalk machine upper end is hinged by stalk machine linking arm and vehicle frame, the middle part that comprises vertical setting with car driving wheel bridge is hinged can be along the adjusting lever of vertical car driving wheel bridge place face rotation, rotation adjusting lever upper end is hinged with the telescopic oil cylinder upper end, and the piston rod outer end and the stalk machine middle and lower part of telescopic oil cylinder are hinged; Rotation adjusting lever lower end and cylinder push rod upper end are hinged, are provided with the roller height adjuster that can regulate its corner dimension between rotation adjusting lever and the cylinder push rod, and cylinder push rod lower end is provided with cylinder.
Both sides, described stalk machine bottom are provided with rail groove, and being provided with in the rail groove can be along the rolling member of rail groove slip, and the two ends of cylinder are connected with rolling member.
The rail groove opening of both sides, described stalk machine bottom is relative inwardly, and the termination of rail groove is provided with postive stop baffle, and vertically being provided with in the rail groove can be along the roller of bottom land rolling, and the roller middle part is provided with screw, and the two ends of cylinder and roller screw are spirally connected.
Roller height adjuster between described rotation adjusting lever and the cylinder push rod comprises push rod, and push rod one end is hinged on the cylinder push rod, and an other end is fixed on the rotation adjusting lever by pin, vertically is provided with at least two fixing holes on the rotation adjusting lever.
Described cylinder push rod lower end is connected with anti-cylinder and takes off the chain rope, and the chain rope other end is connected with stalk machine linking arm; Cylinder push rod lower end is connected with the stalk machine and rises lifting rope synchronously, and the lifting rope other end is connected with stalk machine middle and lower part.
After having adopted this structure, cylinder is subjected to the resistance change greatly when running into upward slope, can promote rotation adjusting lever lower end causes it to turn clockwise, the upper end and the telescopic oil cylinder of rotation adjusting lever are hinged, thereby the piston rod that drives telescopic oil cylinder moves forward, because stalk machine upper end by being connected with the hinged stalk machine linking arm of vehicle frame, is subjected to when stalk machine bottom just can lifting after the effect of piston stick force.When running into descending, the stalk machine is owing to gravity moves down, thereby the rotation adjusting lever is rotated counterclockwise, and the piston rod of telescopic oil cylinder moves backward, causes the stalk machine to move down.Thereby realized the stalk machine according to road conditions adjust automatically the height.The utility model is simple in structure, practical, and low cost of manufacture can well realize regulating automatically the height of stalk machine, and is easy to utilize.
