Embodiment 1

[0049] figure 1 with figure 2 It is a schematic diagram of the structure of the handle bar of an existing agricultural motor vehicle, which can be manipulated in the front, back, left, and right directions.

[0050] Such as Figure 3-Figure 12 As shown, a position-adjustable handle rod of this embodiment includes a handle rod welded 1, a limit bracket 2, a rotating support 3, a pull rod 4, and a limit pin 5. The handle rod is welded 1 and the lower end is hinged. On the rotating support 3, the limit bracket 2 is fixed in the middle of the handle bar welding 1, the limit bracket 2 is provided with a guide groove 21, and the pull rod 4 is movably arranged at the limit position. Arranged side by side on the bracket 2 and welded with the handle rod 1, a limit pin 5 is provided at the lower end of the pull rod 4, and the limit pin 5 is elastically connected to the limit bracket 2 and is located in the guide groove 21 The rotation support 3 is provided with a number of limit slots 31 ...

Embodiment 2

[0069] Such as Figure 3-Figure 12 As shown, an agricultural machinery steering handle of this embodiment includes a fixed seat 100, a rotating seat welding 200, and the handle rod. The bottom of the rotating support 3 is installed with the handle rod welding 1 perpendicularly arranged The second shaft sleeve 300; the fixed seat 100 is installed with a first rotating shaft 400; the rotating seat welding 200 includes a third shaft sleeve 500, a connecting rod 600 and a second rotating shaft 700, the third shaft sleeve 500 The second shaft 700 and the second shaft 700 are respectively connected to the connecting rod 600 vertically, the third shaft sleeve 500 and the second shaft 700 are misaligned and arranged vertically; the second shaft sleeve 300 is sleeved on the On the second rotating shaft 700, the third shaft sleeve 500 is sleeved on the first rotating shaft 400.

[0070] The steering handle of this embodiment can switch between different operating angles according to the ne...

Abstract

The invention relates to a position adjustable handle lever and an agricultural machinery steering handle. The position adjustable handle lever comprises a handle lever seaming, a limiting bracket, arotary support, a pull rod and a limiting pin, wherein the lower end of the handle lever seaming is hinged to the rotary support; the limiting bracket is fixed in the middle of the handle lever seaming; a guiding groove is formed in the limiting bracket; the pull rod is movably arranged on the limiting bracket; the pull rod and the handle lever seaming are arranged side by side; the limiting pin is arranged at the lower end of the pull rod, is in elastic connection onto the limiting bracket and is positioned in the guiding groove; a plurality of limiting grooves are sequentially formed in therotary support side by side; the limiting bracket is partially coincided with the rotary support, so that the guiding groove can be partially coincided with any of limiting grooves when the handle lever seaming rotates relative to the rotary support, wherein when the handle lever has position switching, the pull rod is pulled to move the limiting pin out of one limiting groove; the handle lever seaming is rotated to another position, so that the guiding groove is corresponding to another limiting groove, and the limiting pin is released and enters another limiting groove.

Description

Technical field [0001] The invention relates to the related technical field of agricultural motor vehicles, in particular to a handle rod with adjustable position and a steering handle for agricultural machinery. Background technique [0002] At present, the steering lift handles of the cab models of agricultural vehicles on the market (such as crawler vehicles) are located on the right side of the cab, and the angle of the joystick lever is fixed, which cannot meet the needs of different people for the comfort of the joystick position. After the control assembly is assembled, the handle bends beyond the console, and it is easy to touch when the driver enters and exits the aisle of the cab, causing misoperation and posing safety risks. Summary of the invention [0003] The technical problem to be solved by the present invention is that the position of the handle lever on the control platform of the current agricultural vehicle cab cannot be adjusted, which cannot meet the driver's...
