Description

Technical Field

[0001] The utility model relates to the technical field of micro-tillage machines, in particular to an upper-type shock-absorbing vertical pipe component, a handrail assembly and a micro-tillage machine. Background Art

[0002] A micro-tiller is a small agricultural machine widely used in plains, mountainous areas and hilly areas. The structure of the handle operating part of the existing micro-tiller is a labor-saving lever type, in which the handle, riser and gearbox are assembled in a prescribed manner and fastened by bolts. However, since the micro-tiller will generate large vibration force during operation, the vibration force will be directly transmitted to the operator's hand through the riser. After long-term use, the operator's arm will become numb, reducing work efficiency. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a top-mounted shock-absorbing riser assembly, an armrest assembly and a micro-tillage machine with a reasonable structural design, which can effectively alleviate the impact of vibration, improve the operating experience, and help ensure work efficiency.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

When in use, the base is installed on the micro-tillage machine, and the armrest is connected to the vertical tube. When the vertical tube is pressed down, its lower end is tilted upward and compresses the shock-absorbing mechanism, and when the vertical tube is lifted up, its lower end moves downward and stretches the shock-absorbing mechanism. In this way, the vibration generated when the micro-tillage machine is working will be absorbed by the shock-absorbing mechanism through axial expansion and contraction, thereby alleviating the impact of the vibration, improving the operating experience, avoiding numbness of the operator's arm, and ensuring work efficiency.

[0007] Furthermore, the lower end of the vertical pipe has a second hinge shaft arranged transversely, two shock absorbing mechanisms are symmetrically arranged along the width direction of the vertical pipe, and both ends of the shock absorbing mechanism are respectively hinged on the first hinge shaft and the second hinge shaft.

[0008] In this way, better shock absorption can be achieved through the two symmetrically arranged shock absorption mechanisms.

[0009] Furthermore, the lower end of the vertical pipe has a flange protruding outward, and the second hinge shaft is welded to the flange.

[0010] Furthermore, the upper ends of the two upright posts are connected with a horizontal plate, and the horizontal plate and the upright posts are bent integrally.

[0011] In this way, the overall strength of the column can be improved, thereby making the shock absorbing mechanism work more stably and reliably.

[0012] Furthermore, the base has two mounting holes corresponding to the columns, and the lower ends of the columns are inserted into the mounting holes and connected by welding.

[0013] Furthermore, the lower end of the vertical pipe has a limiting portion which is spaced apart from the upper surface of the base, the limiting portion is arranged on both sides of the rotating shaft in a horizontal radial direction, and the minimum distance between the limiting portion and the rotating shaft is greater than the maximum distance between the rotating shaft and the base.

[0014] Furthermore, the lower end of the vertical pipe has a limiting plane arranged opposite to the upper surface of the base, and the limiting portion is two side edges of the limiting plane in the horizontal radial direction of the rotating shaft.

[0015] Furthermore, the base includes a bottom plate and a hinge seat connected to the bottom plate, and the hinge seat has two side plates that are symmetrically bent upward; the vertical pipe is bent in a U shape as a whole, and the U-shaped opening side faces the hinge seat; one end of the hinge seat is covered inside one end of the vertical pipe, and has a first hinge hole coaxially arranged along the width direction, and the rotating shaft is a bolt passing through the first hinge hole; the shock absorbing mechanism is a spring shock absorber, a hydraulic damping shock absorber or a pneumatic damping shock absorber.

[0016] A handrail assembly is characterized by comprising a handrail frame and the top-type shock-absorbing riser assembly as described above, wherein the handrail frame is connected to the riser of the top-type shock-absorbing riser assembly.

[0017] A micro-tillage machine is characterized by comprising the armrest assembly as described above.

[0018] In summary, the top-type shock-absorbing riser assembly, handrail assembly and micro-tillage machine of the utility model have the advantages of reasonable structural design, can effectively alleviate the impact of vibration, improve operating experience, and are conducive to ensuring work efficiency.
