It is circular sleeve pipe provided with inner surface section, described sleeve pipe is set in outside the transmission shaft tube；On the outer wall of the transmission shaft tube
Provided with central siphon block, the wheel placenta is provided with wheel placenta block, and the central siphon block can be by the wheel in rotary course
Placenta block blocks.
In said structure, transmission shaft tube is used to passing to the rotary power of rectangular tube into the sleeve pipe on wheel placenta, but simultaneously
Retain the function that sleeve pipe can rotate certain radian relative to transmission shaft tube and rectangular tube, so being provided with central siphon in transmission shaft tube
Block, wheel placenta block is provided with wheel placenta, and central siphon block can be blocked in rotary course by wheel placenta block, with
Realize transmission agency；On this architecture basics, wheel placenta can be rotated against on transmission shaft tube close to 360 ° just can again by
Block, turned so this just rotates for tire and wheel placenta relative to transmission shaft tube, rectangular tube and lower box assembly output shaft with realizing
The bigger function of rotation radian of outside tire provides possibility when curved, and so as to realize flexible turning, this is that this practicality is new
The innovation emphasis of type.
For the ease of connection transmission shaft tube and rectangular tube and the rotary limited of sleeve pipe is realized, the transmission shaft tube and the side
It is welded to connect between shape pipe, the central siphon block is installed on the first end of the transmission shaft tube, and the central siphon block is positioned at described
The outside of the first end of sleeve pipe and the first end that can block described sleeve pipe, the second end of the transmission shaft tube stretch out in the set
Outside second end of pipe, the second end of the rectangular tube is stretched out in outside the second end of the transmission shaft tube, and the second of the rectangular tube
End is outer to be installed with positioning sleeve, and the positioning sleeve can block the second end of the transmission shaft tube.
Specifically, the rectangular tube is hexagonal tube, and the inner surface section of the transmission shaft tube is hexagon.
Specifically, two rectangular tubes are separately mounted to the both ends of the lower box assembly output shaft, two transmissions
Central siphon is set in outside two rectangular tubes, and the sleeve pipe in two tire cover for seat is set in two transmissions
Outside central siphon, two tires are separately mounted in two tire cover for seat.
The beneficial effects of the utility model are：
On the one hand the utility model is easy to be connected realization with original rectangular tube by increasing square internally and round externally transmission shaft tube
Transmission between rectangular tube and transmission shaft tube, the central siphon block on the other hand to be cooperated by setting and wheel placenta block are realized
Transmission between transmission shaft tube and wheel placenta, it is final to realize lower transmission between box assembly output shaft and tire；Meanwhile utilize biography
On-fixed attachment structure between moving axis pipe and wheel placenta, the rotation radian of outside tire when mini-tiller is turned can be realized easily
Bigger function, so as to realize the flexible turning function of mini-tiller.
Brief description of the drawings
Fig. 1 is the stereogram of flexible mini-tiller tire turning mechanism described in the utility model of turning.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, flexible mini-tiller tire turning mechanism described in the utility model of turning is by lower box assembly output shaft 2
Driving, including two hexagonal tubes, 8, two wheel placentas 4 and two tires 1, in addition to two inner surface sections are hexagon, outside
Surface sections are circular transmission shaft tube 5, the first end of two hexagonal tubes 8（It is i.e. inner）It is separately mounted to lower box assembly output
The both ends of axle 2 are simultaneously sleeved on outside lower box assembly output shaft 2, the first end of two transmission shaft tubes 5（It is i.e. inner）It is set in two
Second end of individual hexagonal tube 8（That is outer end）Outside and it is sleeved on outside hexagonal tube 8, is welded between transmission shaft tube 5 and hexagonal tube 8
Connect, the center of wheel placenta 4 is provided with inner surface section as circular sleeve pipe 4-1, and two sleeve pipe 4-1 are set with to be driven in two
Outside central siphon 5；Central siphon block 5-1 is respectively equipped with the outer wall of the first end of two transmission shaft tubes 5, is set respectively on two wheel placentas 4
Have and take turns placenta block 4-2, central siphon block 5-1 can be blocked in rotary course by corresponding wheel placenta block 4-2；Two central siphons
Block 5-1 positioned at the outside of two sleeve pipe 4-1 first end and can block corresponding sleeve pipe 4-1 first end respectively, and two pass
Second end of moving axis pipe 5 stretches out in outside two sleeve pipe 4-1 the second end respectively, and the second end of two hexagonal tubes 8 is stretched out respectively
In outside the second end of two transmission shaft tubes 5, being installed with positioning sleeve 11 outside the second end of two hexagonal tubes 8 respectively, two
Positioning sleeve 11 can block the second end of two transmission shaft tubes 5 respectively.Above-mentioned central siphon block 5-1 and wheel placenta block 4-2
Using pin.
Lower box assembly 3 is also show in Fig. 1, for connecting the bearing pin 7 and B shapes of hexagonal tube 8 and lower box assembly output shaft 2
Pin 6, for connecting the hex bolts 9 and hex nut 10 of hexagonal tube 8 and positioning sleeve 11, these are conventional fitment, so
This is only briefly described.
As shown in figure 1, using when, the transmission process of mini-tiller straight line moving is as follows：
The lower box assembly output shaft 2 of lower box assembly 3 rotates, and two hexagonal tubes 8 of driving rotate, and drive two transmission shaft tubes
5 are rotated, and the central siphon block 5-1 on transmission shaft tube 5 can be kept off in rotary course by the wheel placenta block 4-2 on two wheel placentas 4
Firmly, so as to drive two wheel placentas 4 to rotate, two tires 1 are driven to rotate, so as to realize the walking function of mini-tiller.
The transmission process that mini-tiller is turned is as follows：
In normal walking, if necessary to turn, then user, which pulls handrails of micro-cultivator, makes its turning, now turning medial
Tire 1 can increase resistance, may result in lower box assembly output shaft 2 rotating speed reduce or stop, the central siphon block 5-1 of inner side with
Wheel placenta block 4-2 is closely packed together all the time；The tire 1 in outside needs the tire 1 than inner side to rotate bigger radian simultaneously,
, can be relative to equivalent to wheel placenta 4 corresponding to the tire 1 in outside under the premise of the both ends rotating speed identical of lower box assembly output shaft 2
The transmission shaft tube 5 in outside rotates bigger radian, now due to the wheel placenta 4 in outside need the direction of rotation of bigger radian rotation with
Direction of rotation originally is consistent, so the wheel placenta block 4-2 on the wheel placenta 4 in outside can be easy to quickly rotate and remote
The central siphon block 5-1 in outside, turned so as to be easily achieved, that is, realize the function of flexibly turning.Due to needed for turning
The difference of outside rotation radian and inner side rotation radian will not be very big, so, outboard wheel placenta block 4-2's approaches in this structure
360 ° of rotatable radian meets the turning demand of general angle enough.After the completion of turning, the central siphon block 5-1 in outside needs to revolve
It could be blocked after turning certain angle by the wheel placenta block 4-2 in outside and realize outside driving function, this is an adaptive mistake
Journey, user do not have to deliberately manage it.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can be realized without creative work on the basis of above-described embodiment, is regarded as falling into
In the rights protection scope of the utility model patent.
