The staircase manipulation device also comprises a second rotating shaft which is driven by an auxiliary power apparatus, wherein the second rotating shaft is fixedly provided with a positioning wheel used for determining the position of the staircase, and the positioning wheel is in fit with the positioning notches. The staircase manipulation device enables a driver to realize rotating, unfolding and folding of the staircase both in a cab and under a shielding platform, and facilitates the driver to get on or off a machine. Meanwhile, the staircase manipulation device improves passing ability and aesthetics of a harvester, and more importantly prevents safety accidents from happening effectively.
Description
Technical field
The utility model relates to the agricultural machinery technical field, particularly a kind of staircase manipulation device that is used for agricultural machinery.
Background technology
Grain header is high with its automaticity, and is time saving and energy saving, easy to operate, and the operating efficiency advantages of higher has obtained using widely.At present domestic grain header driver's cabin is overhead all higher, and personnel are very inconvenient up and down, need get on or off the bus through ladder.And the ladder that disposes on original type is deployed in the vehicle body outside, has increased the width of car load, has influenced the trafficability characteristic of car load; Also influenced the aesthetic property of car load; And security incident takes place easily, therefore be badly in need of a kind of staircase slewing maneuver device of exploitation, make ladder when not using, to turn to the bridge bottom through this device; Be not deployed in the vehicle body outside, to avoid security incident.
The utility model content
The utility model purpose is in order to overcome above-mentioned deficiency, a kind of staircase manipulation device that is used for agricultural machinery that can make staircase when grain header is walked, be turned back to under-cab to be provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the staircase manipulation device that is used for agricultural machinery; Comprise first rotating shaft that is fixedly installed togather with said staircase, an end of said first rotating shaft is installed with locking wheel, and said locking wheel is provided with at least two polarizing slots; Described staircase manipulation device also comprises second rotating shaft that is driven by auxiliary power unit, and fixed installation is useful on the locating wheel of confirming said staircase position in said second rotating shaft, and said locating wheel and polarizing slot are suitable.
As a kind of improvement, said auxiliary power unit comprises the connecting rod that is fixedly installed in said second rotating shaft, and said connecting rod is connected with controlled pedal.
As further improvement, said auxiliary power unit comprises the control crank that is fixedly installed in said second rotating shaft.
The beneficial effect of the utility model is: because staircase is fixedly connected with locking wheel through first rotating shaft; And locking wheel is provided with the suitable otch of locating wheel that drives with auxiliary power unit; So the driver drives locating wheel at driver's cabin steering maneuver device and rotates, when the polarizing slot of locating wheel rotated to the position that locking wheel can pass through, staircase just can be rotated; When personnel need get on or off the bus, staircase is screwed out; When grain header need be walked, can staircase be screwed into the below of driver's cabin; Because locking wheel is provided with polarizing slot, when the staircase rotation puts in place, play effect into the staircase location, avoid fixing because of the staircase position, security incident takes place and swing.
Owing to also be connected with control crank in second rotating shaft, can make human pilot below the guard shield platform, also can easily handle the rotation of staircase, convenient for passenger to get on and off.
In sum, the utility model can realize that the driver all can easily realize the rotary expansion and the closure of staircase in driver's cabin and below the guard shield platform, make things convenient for the driver to get on or off the bus; Also improved the trafficability characteristic and the aesthetic property of grain header simultaneously, main is the generation of effectively having avoided security incident.
