Description
Technical field
The utility model is related to field of power machinery technology, and in particular to one kind limit shelves formula armrest seat.
Background technology
Mini-tiller using small diesel engine or gasoline engine as power, be widely used in Plain, mountain area, the nonirrigated farmland on hills, paddy field,
Orchard etc..The operation such as mix corresponding equipment and can be drawn water, generated electricity, sprayed, sprayed, can also draw towed vehicle and carry out short distance fortune
Defeated, mini-tiller can freely exercise progress field management in field, and user-friendly and storage eliminates large-scale farm machinery
It cannot be introduced into the worry of mountain area field.Mini-tiller generally includes frame and the traveling wheel being connected in frame, cultivated knife, handrail etc.,
Traveling wheel and cultivated knife are arranged side by side, and handrail direction ploughs side of the knife away from traveling wheel.
Carry out field management for convenience, mini-tiller usually can multi-gear adjustment to adapt to different use demands, especially
It is that commutation traveling is may require that when part mini-tiller is used, because the cultivated knife of mini-tiller is usually located between traveling wheel and handrail, changes
Situation after one's death can not be observed to the operator of hand-held handrail during traveling, if falling accidentally, cultivated knife is easy to make operator
Into injury, there is potential safety hazard.The handrail that can be commutated is have developed in order to solve the problem, makes handrail when mini-tiller commutates
It can rotate and be easy to operator's adjustment position, but be due to the no adjustment simultaneously of gear of mini-tiller after commutation, be still within height
Fast shelves and operator is located on the preceding line direction of mini-tiller after commutating, there is potential safety hazard when actual use, operator needs to use
Very big power goes to control mini-tiller, while the situation of observation after one's death, prevents mini-tiller out of control, operates very inconvenient.Prior art
Scheme is the gear that mini-tiller is limited after commutation, makes to be in low or first gear after commutation all the time, it is easier to which operator controls, reduction peace
Full blast danger, but there is presently no the function that preferable structure can realize above-mentioned limitation gear.
Utility model content
The utility model is intended to provide a kind of limit shelves formula armrest seat, to limit gear after commutation, solves existing mini-tiller
Gear can not obtain the problem of limitation is present compared with high safety hidden danger after commutation.
To reach above-mentioned purpose, basic technology scheme of the present utility model is as follows：One kind limit shelves formula armrest seat, including gear shift
Provided with line shaft, the gearshift tooth set being connected with line shaft spline in case, gear shift case, gearshift tooth is put is respectively equipped with nipper successively
Wheel, neck and backgear；Also include base, base be fixed in the middle part of the upper end of gear shift case, base upper end be rotatably connected to it is perpendicular
To the handrail of installation, base on the outside of limiting plate, handrail is fixed with handrail it is provided with via, via and be equipped with vertical installation
Depression bar, the top of depression bar is fixed with pressing plate, and the bottom of depression bar is fixed with briquetting, is arranged with the depression bar between pressing plate and base
Dynamic clamping head and quiet clamping head；Gear shift case is rotatably connected to gear shift piece on the side wall of depression bar, and gear shift piece is located at the lower section of depression bar, piece of shifting gears
With gearshift tooth set clamping.
The principle and advantage of this programme be：During practical application, gear shift tooth, which is enclosed on, to be slided on line shaft with the different shelves of correspondence
Position, gear shift piece is rotatably connected on gear shift case and is connected with gearshift tooth set, and the different rotational angle correspondence mini-tiller of gear shift piece is not
Same gear, piece of so the shifting gears position that adjustable tooth of shifting gears is enclosed on line shaft when rotating, so as to change gear.Normally make
Limiting plate on used time, handrail departs from pressing plate, and the briquetting of depression bar lower end is hanging in the presence of dynamic clamping head and quiet clamping head, and gear shift piece can
Rotated in the corresponding angular range of whole gears, realize the top gear of mini-tiller to the regulation of reverse gear.Need to change in mini-tiller
To in use, rotary handle is to adapt to operation centered in the middle part of base, base provides support and certralizing ability for handrail.Handrail
Limiting plate is also and then rotated during rotation, and pressing plate is pressed downward by handrail when rotating, and handrail is gone to the position rear position margining plate gear of needs
In the upper end of pressing plate, depression bar resilience is prevented, the lower end of depression bar keeps off the activity that gear shift piece is limited in the top of gear shift piece through base
Scope, when handrail Rotation With Changing backward, depression bar limits the slewing area of gear shift piece, makes gear shift piece can only be in fixed angular range
It is interior to rotate so as to be moved between the gear positions that gear shift tooth set can only be fixed on line shaft, realize the limitation of gear so that micro-
Gear is restricted after the machine of ploughing commutation, it is possible to achieve only in low-grade location work after commutation, reduces high tap position work meeting after commutation
The security risk brought.When commutating again, handrail returns to normal condition, and limiting plate departs from pressing plate, and pressing plate is in elastic reset
By upward jack-up in the presence of the recovery deformation of part, depression bar and briquetting is driven to move up, briquetting no longer limits the work of gear shift piece
Dynamic scope, gear shift piece can change in top gear between reverse gear again.So can be effectively according to actual use by this programme
Situation controls the transforming gear of mini-tiller, and mini-tiller can be particularly limited when commutation is used and is in underdrive operating state, micro-
The machine of ploughing uses safer.
