Description
Technical field
The present invention relates to a kind of walking box of micro tillage machine, especially a kind of walking box of micro tillage machine turn to clutch.
Background technology
The walking box of micro tillage machine of prior art, because conventional Shift Computation V shape clutch structure conflicts mutually with the installation site of rotary blade, designer must consider to arrange left and right turn clutch in the axial dimension of about 20cm, cause difficult design, on market, most of mini-size tillage machine does not have left and right turn clutch, its field turns to inconvenience, especially ploughs headland, and operation is extremely required great effort; In addition, owing to turning to inconvenience, carry additionally trench digging, hoe up weeds, apply fertilizer, the facility such as ploughing on rear side of body, operating difficulties, is difficult to realize multi-functional assembly.Number be the Chinese utility model patent of 20092020673.7, disclose the walking structure that a kind of band turns to clutch, adopt traditional shifting fork mechanism, its structure inconvenience rotary blade is installed, and can only install rotating rotary blade afterwards on rear side of body.Market once occurred a kind of band turns to the mini-size tillage machine of clutch, but complex structure, cost is high.The Chinese invention patent of the CN102487612B of the applicant, what disclose a kind of mini-size tillage machine turns to clutch, bead string type shifting fork mechanism is adopted to achieve left and right turn clutch operation, because its clutch-plate throws off the axial force needed for power, need operator to pass through firmly to pull clutch line directly to apply, there is the problem of operation effort.Mini-size tillage machine market needs a kind of structure is simpler, operation is lighter, being convenient to realize multi-functional assembly turn to clutch.
Summary of the invention
The problem that the present invention solves is to provide a kind of and turns to clutch for mini-size tillage machine, and its left and right turn flexible operation is light, and structure is simple, is convenient to realize multi-functional assembly.
The present invention adopts following technical scheme: comprise tank shell, power shaft, output shaft, master hub, clutch plate, clutch lever, it is characterized in that: described output shaft is semi-axis structure, described master hub is provided with a pair first chimeric ends, described clutch plate comprises a pair clutch discs being located at the master hub left and right sides, clutch discs the inner be provided with chimeric with first hold match second be fitted together to hold, clutch discs outer end is provided with clutch dop, clutch discs is installed on output shaft by the first return spring, also comprise a dead bolt shifting fork mechanism, described dead bolt shifting fork mechanism comprises the telescopic tongue being connected with clutch line, connect with clutch lever after the external end head of clutch line upwards passes tank shell by the inner chamber of tank shell, tank shell is provided with second return spring that can control the action of clutch line, clutch lever is by the expanding-contracting action of clutch line traffic control telescopic tongue, telescopic tongue is arranged in a tongue apertures of tank shell relevant position, telescopic tongue is provided with radial the first working face extended, described clutch dop is provided with radial the second working face extended, first working face and the second working face match.
Its principle is: usually under state, clutch dop and telescopic tongue are separated from each other (that is: the first working face and the second working face are separated from each other), and now under the first return spring effect, clutch discs is combined with master hub and connects power.When needing to throw off power, operator is exerted a force by clutch lever, clutch line traffic control telescopic tongue moves to axis direction, first working face moment of telescopic tongue contacts with the second working face of clutch dop, telescopic tongue is under revolving force effect, the axial resistance overcoming the first return spring pushes away master hub clutch discs, throws off power.In like manner, unclamp clutch lever, under the effect of the second return spring, telescopic tongue moment oppositely moves away clutch dop, and the first return spring promotes clutch discs immediately and is combined with master hub and connects power.This structure, clutch line upwards passes the tank shell of walking case by the inner chamber of tank shell, two semiaxis can complete the setting of left and right turn clutch in the axial dimension of about 20cm, walking case compact overall structure, as common walking box of micro tillage machine, output shaft can install rotary blade.
A kind of improvement is that described tongue apertures is made up of a dead bolt mounting disc and tank shell assembly, and dead bolt mounting disc and tank shell pass through thread connection.
Another kind of improvement is that described dead bolt shifting fork mechanism comprises a telescopic tongue and a clutch dop matched.
A kind of improvement is also had to be that described dead bolt shifting fork mechanism comprises two telescopic tongues and two clutch dops matched.
Further improvement is, described dead bolt shifting fork mechanism comprises three telescopic tongues and three clutch dops matched.
Tool of the present invention has the following advantages: 1, rapid operation is light, and clutch state conversion flexibly and fast.Clutch-plate throws off the axial force needed for power, is to contact produced axial thrust by the first working face of the clutch discs in rotation with the second working face to realize, and does not need operator directly to exert a force.2, walking case compact overall structure, clutch structure does not conflict mutually with the installation site of rotary blade.3, structure is simple, and be easy to processing, cost is low.4, owing to having left and right turn function, trench digging can be installed on rear side of body, hoe up weeds, apply fertilizer, the facility such as ploughing, realize multi-functional assembly.
