Description

A kind of full tooth converter of mini-tiller

Technical field

Agricultural machinery technological field is the utility model is related to, more specifically, more particularly to suitable for field broadcasts cultivated use A kind of full tooth converter of mini-tiller.

Background technology

Two semiaxis of the steering gear of existing mini-tiller are respectively by being fixed on the half axle gear and planetary gear of its end Engagement position, in the process of moving, drive mechanism drives planetary gear rotation, and planetary gear drives half axle gear to rotate, entered And the motion driven with the road wheel of half axis connection, therefore, the engaging friction between half axle gear and planetary gear are rotated by semiaxis The mechanical wear of two gears can be caused, and then cause the axiality of two half axle gears to reduce, influence the change of the output torque of semiaxis Change, and then cause the uncoordinated of two road wheels, influence turn performance；Or steering gear is linked by chain type, principal organ is chain Wheel, planet tooth axle, planetary gear and half axle gear, symmetrical planetary gear mounting hole are opened up on the wheel face of sprocket wheel, planet tooth axle is consolidated It is scheduled on the planetary gear mounting hole, planetary gear is arranged on planetary gear, and half axle gear connects with planetary gear engaged transmission Connect, these steering gears are present：Turn to dumb, it is impossible to which more preferable effective farming, mechanical part abrasion is fast, overall service life of a machine The shortcomings that short.

Utility model content

For the drawbacks described above and problem of prior art, technical problem to be solved in the utility model is to provide a kind of micro- Machine full tooth converter is ploughed, can be made in mini-tiller walking process, reaches steering flexibly in, light and handy, and the effect of safety.

In order to achieve the above object, the utility model provides following technical scheme：

A kind of full tooth converter of mini-tiller, including driving cog, clutch tooth, spring, shift fork, semiaxis, clutch mandrel, bushing, The semiaxis is socketed in clutch mandrel, and semiaxis one end sets rotating hole, and clutch mandrel both ends are separately positioned on the rotating hole of semiaxis In, the clutch tooth and driving cog are socketed, and spring is fixed in the neck on semiaxis, and spring withstands clutch tooth, the shift fork with The bayonet connection of clutch tooth.

In above-mentioned technical proposal, the rotating hole is the axis hole opened up vertically on semiaxis.

In above-mentioned technical proposal, the clutch tooth is circumferentially to set tooth.

In above-mentioned technical proposal, the clutch number of teeth is 6-14, is set along clutch tooth even circumferential.

In above-mentioned technical proposal, at the driving cog center, both sides set receiving space respectively, and it is empty that semiaxis is arranged on receiving Between in.

The utility model is simple in construction, reasonable in design and using effect is good, and flexible, side is more turned on the basis of original Convenient to operate is in the case where combination is tightened, departs from steering, preferably effectively ridging, trench digging, fertilising.

Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on this practicality Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made Example is applied, belongs to the scope of the utility model protection.

According to Fig. 1-Fig. 7, as the full tooth converter of a kind of mini-tiller shown in embodiment, critical piece is：Transmission Tooth, clutch tooth, spring, shift fork, semiaxis, clutch mandrel, bushing.

Concrete structure is：Semiaxis is two, and semiaxis is socketed in clutch mandrel, is opened in one end of semiaxis along the axial direction on semiaxis If rotating hole, hole depth 20cm -35cm is rotated, clutch mandrel both ends are separately positioned in the rotating hole of semiaxis, driving cog center Place, after driving cog both sides set receiving space, semiaxis to be combined with clutch mandrel respectively, into receiving space, semiaxis, which is set, to be held Receive the outer wall in space, be uniformly arranged 3-6 convex wings, convex wing prevents semiaxis from being slid in the receiving space of driving cog, and semiaxis is set Neck, spring are fixed in the neck on semiaxis, and spring withstands clutch tooth, and driving cog is circumferentially uniformly arranged 6 in clutch tooth- 14 teeth, clutch tooth are socketed with driving cog, and clutch tooth sets the bayonet connection of bayonet socket, shift fork and clutch tooth.

Principle of the present utility model is：Shift fork is connected with mini-tiller, and clutch tooth and driving cog combine, clutch tooth and driving cog It is locked under spring action, during steering, shift fork transfers to clutch tooth, and clutch tooth and driving cog separate can and turned to；Then Clutch tooth under spring force, promotes clutch tooth, realizes that clutch tooth is combined with driving cog, reach locking.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be described with power The protection domain that profit requires is defined.
