Description
Technical field
The invention belongs to technical field of agricultural machinery, specifically disclose a kind of mini-tiller shift drag link mechanism.
Background technology
Using small diesel engine or gasoline engine as power, rotary tillage can be completed, ploughing, sowing, take off mini-tiller by being equipped with corresponding farm implements
Grain such as draws water, sprays, generates electricity and transports at the multi-mode operations.Mini-tiller have it is light-weight, it is small, it is simple in structure the features such as, extensively
Suitable for areas such as Plain, mountain area, hills.Mini-tiller can also draw towed vehicle and carry out short-distance transport, can be in field free walker
When, user-friendly and storage eliminates the worry that large-scale farm machinery cannot be introduced into mountain area field, is vast farmers consumption
Person substitutes the cultivated best tool of ox.
The shifting-position mechanism for converting its moving situation is equipped on mini-tiller, existing shifting-position mechanism is the shift in mini-tiller
One pull rod is installed, pull rod is slidably connected on the arm-rest frame of mini-tiller, by front and back push-and-pull pull rod, makes shift arm swing on arm
Realize shift.This gearshift has the following problems：Shift arm swing needs much power when 1, shifting gears, it is necessary to apply to pull rod
Same power carries out front and back push-and-pull, and gear arm is usually connect with the power shift gear case in mini-tiller, and rotation needs larger
Force effect so that this gearshift is very laborious when operating；2, it is changed since above-mentioned gearshift needs to apply larger power
Gear, operator is more difficult to control when applying compared with great dynamics, be easy to cause and trip stops, if operator has little time, interim strain controlling is micro- to be ploughed
Machine is prone to accidents；3, when the front and back push-and-pull of pull rod is shifted gears, the hand of operator will be with pull rod back-and-forth motion, if behaviour
Author station is possible to can't reach pull rod in pushing drawing rod in the hand away from pull rod remote position, operator；If operator station exists
From pull rod it is closer with a distance from when, if the hand operated dynamics when pulling pull rod controls the improper body that pull rod can be made to bump against operator
Body is damaged to operator；4, above-mentioned gearshift usually not gear identifies, or gear is marked on mini-tiller
Side is not easy to operator and checks gear.
Invention content
The purpose of the present invention is providing a kind of mini-tiller shift drag link mechanism, is operated with solving existing gearshift
The problem of causing high effort for.
In order to achieve the above object, base case of the invention is：Mini-tiller shift drag link mechanism, including shift outer cover,
Nestling plate, upper shift lever, the lower shift lever being connect with gear arm, the shift supporting rod being fixed on arm-rest frame；Outside the shift
The lower end of cover, which is fixed, to be nested on shift supporting rod, top and the shift supporting rod rotation connection of the nestling plate, nestling plate
Lower part is rotatablely connected with lower shift lever, and the middle part of nestling plate is fixedly connected with upper shift lever；The upper surface of the shift outer cover is set
There is mark, the upper end of the nestling plate is in the pointer shape for being directed toward mark.
The operation principle of this base case is：When shift, exert oneself in the vertical direction to the free end of upper shift lever, i.e.,
The free end of shift lever is changed in upper lift or pushing；The fixing end of upper shift lever and the middle part of nestling disk are fixed, upper shift lever
Free end stress, power will be transferred to nestling plate by upper shift lever so that the middle part of nestling plate is by upper and lower active force.It is young
The upper end of bird plate is fixed on shift supporting rod rotation connection, shift supporting rod on arm-rest frame, and the middle part stress of nestling plate can make
The top of nestling plate is along shift supporting rod rotation, to drive the lower end swing of nestling plate.The lower end of nestling plate is changed under
Bar is rotatablely connected, and the lower end of nestling plate, which is swung, will pull lower shift lever to move forward and backward, to pull gear arm swing
Realize shift.
When being shifted gears using mechanism, the upper end of nestling plate will be with the top rotation of nestling plate and swing, nestling plate
Upper end is in the pointer shape for being directed toward mark；Therefore when nestling plate is swung, the upper end of nestling plate will be different on carton shift outer cover
Mark；Since mark is arranged in the upper surface of shift outer cover, operator overlooks i.e. it can be seen that mark.
Above-mentioned upper shift lever and the fixing end that the fixed one end of nestling plate is upper shift lever, the other end are then upper shift lever
Free end.
The advantageous effect of this base case is：Mechanism turns gear shift operation from the force mechanism of original front and back push-and-pull
The force mechanism for carrying pressure off is changed into, to make operator's hand when operating shift prevent from operating without being moved forward and backward with pull rod
When person operates shift beyond reach or the case where pull rod can bump against operator's body.The above shift lever of mechanism, nestling board group
At lever, using the top of nestling plate at shift supporting rod rotation connection as fulcrum, since the free end of upper shift lever is to fulcrum
Distance be far longer than fulcrum to the distance of nestling plate lower end so that mechanism composition lever be laborsaving lever；Only need
The free end of upper shift lever applies smaller active force, you can so that the lower part of nestling plate is had larger oscillatory forces, under making
Shift lever is realized shift by larger pulling force.Apply smaller power in mechanism and shift, smaller power operator can be realized
It is easily controlled, the case where gear shift occurs to greatly reduce, reduce accident rate.Mark setting is being changed in mechanism
The upper surface of outer cover is kept off, operator overlooks i.e. it can be seen that mark, very convenient operator check gear situation.With prior art phase
Than mechanism is laborsaving, is conveniently operated, and has also effectively reduced the case where trip stopping.
