Description
Technical field
The present invention relates to agricultural machinery component and parts field, in particular to a kind of mini-tiller emergency stop device and mini-tiller.
Background technique
Mini-tiller plays increasing effect as a kind of farm machinery in agricultural development.What mini-tiller leaned on is
Rotary tillage blade is ploughed, if different from general land walking wheel being that the rotation misoperation of Rotary tillage blade will cause and cut
The safety accidents such as wound, thus, security risk is greater than general walking machine；In specific structure, the rotation of Rotary tillage blade is walked
It is to be driven by driving spindle, and driving spindle is to be inputted engine power by clutch, forms drive chain；Clutch
All there is the time difference, when driving clutch separation by shift fork, the response time of clutch is longer, and main for separation and engagement
For axis under the action of inertia force, will cause Rotary tillage blade continues rotation walking, to cause security risk, especially wet type from
Clutch, the above problem is even more serious, or even more serious safety accident can occur.
Therefore, it is necessary to existing mini-tiller driving and halt system improve, it is ensured that clutch disconnect when by
Coulter on the Rotary tillage blade of driving spindle driving can stop in time, so that the influence for being driven main shaft inertia is eliminated, from
And guarantee the personal safety of operator.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of mini-tiller emergency stop device and mini-tillers, it is ensured that disconnected in clutch
It can be stopped in time when opening by the coulter on the Rotary tillage blade of driving spindle driving, to eliminate the shadow for being driven main shaft inertia
It rings, to guarantee the personal safety of operator.
Mini-tiller emergency stop device of the invention, including being fixed on the frictional disk of driving spindle in circumferencial direction and for driving
The shift fork of clutch on-off, between frictional disk and clutch, the shift fork is applied to frictional disk and is used for the shift fork
The pretightning force that frictional disk is braked；It further include the actuator for overcoming shift fork the preload power drive clutch to engage；It is ploughed when micro-
When machine works normally rotary tillage, shift fork drives clutch to engage under external force, and driving spindle is driven by the engine rotation, thus
Drive rotary cultivator rotation；When needing to stop, external force shift fork leaves clutch, then clutch disconnects power drive chain, together
When, shift fork is affixed to frictional disk by preload power drive, friction catch is formed, so that the rotary blade of mini-tiller stops in time；It is described pre-
The application of clamp force can use various structures, can be column spring and directly apply, the torsional spring etc. being also possible in shift fork axle.
Further, the shift fork is fixedly installed on shift fork axle in circumferencial direction, and the pretightning force of the shift fork is dialled by being set to
Pretightning force torsional spring on fork shaft applies, and applies pretightning force using torsional spring, structure, which is simply installed, to be easy and do not increase cost, torsional spring
One end is fixed in shift fork axle, and the other end is fixed on the fixed component such as cabinet, and details are not described herein.
Further, the shift fork is equipped with the rubbing surface for cooperating with frictional disk, is flapped toward in the pretightning force shift fork
When frictional disk, the rubbing surface fits in the frictional disk, can increase coefficient of friction using rubbing surface, has emergency stop effect good
Good advantage.
Further, the rubbing surface and shift fork facade are in set angle, when being flapped toward friction in the pretightning force shift fork
When disk, the rubbing surface fits in the frictional disk in parallel, the set angle with shift fork installation site and frictional disk with from
The distance between clutch is related, and parallel fitting has biggish contact surface, to improve braking efficiency.
Further, the rubbing surface is formed by friction material layer, and friction material is pasted on shift fork, is similar to brake gear
And the friction plate material of clutch, metal dish then can be used in frictional disk at this time, and save the cost and installation, which manufacture, to be easy.
Further, the rubbing surface is divided into two prongs that two parts are respectively formed in shift fork, from symmetrical orientation to rubbing
It wipes disk and forms friction, so that friction is uniformly, improve the service life of component；Guarantee the whole uniformity of braking simultaneously.
Further, two prongs of the shift fork form prominent step, the height of the prominent step relative to rubbing surface
When rubbing surface fits in the frictional disk in parallel positioned at the radial outside of the frictional disk；The step is by rubbing surface relative to logical
Normal plane sinks to being formed, and step is located at the radial outside of frictional disk, and structural integrity is strong；In braking, for shift fork
Certain position-limiting action is played, mounting structure is avoided to damage, so that motion artifacts are avoided the formation of, so that braking effect is good
It is good.
Further, two prong ends of the shift fork it is arc-shaped to clutch direction protrude, the structure for drive from
The clutch of clutch has lesser contact area, and drive efficiency is higher and has preferable balance, is conducive to extend moving component
Service life.
Further, the shift fork drive clutch engagement when, between the frictional disk and rubbing surface have setting away from
From the time that pretightning force shift fork is bonded frictional disk with rubbing surface when the distance is released shift fork is not more than two
Second；The size of reasonable set pretightning force and above-mentioned spacing can control braking time, to guarantee effective safety.
The invention also discloses a kind of mini-tiller, the mini-tiller is equipped with the mini-tiller emergency stop device.
Beneficial effects of the present invention: mini-tiller emergency stop device of the invention and mini-tiller are formed actively using shift fork
Braking, directly brakes driving spindle when driving clutch separation, so that Rotary tillage blade be made to stop in time, avoids occurring to expect not
The safety accident arrived；Present invention ensure that can be timely by the coulter on the Rotary tillage blade of driving spindle driving when clutch is disconnected
Stop, so that the influence for being driven main shaft inertia is eliminated, to guarantee the personal safety of operator, and structure of the invention
Reasonable set pretightning force and the installation site of shift fork, clutch at a distance from frictional disk, can reasonable set braking time, structure
Simply, do not increase cost of manufacture.
