Description
Technical field
The invention belongs to rice transplanter technical field, has particularly related to a kind of rice transplanter walking box bevel gear differential and has slowed down
Device.
Background technology
Rice transplanter is the planting machinery being planted in rice seedling in paddy field, which raises the speed of rice transplanting and is planted
Quality, rational close planting is realized, be advantageous to the mechanization of subsequent job.In the rice transplanter of prior art, it is desirable to realize rice transplanting
The normal work of machine, just have to handle by deceleration.Chinese utility model patent " U of CN 205921993 " discloses one kind
Steering mechanism and traveling box are incorporated in one by the rice transplanter walking box of entitled " rice transplanter walking box with turning function "
Rise.Upper box and the lower box rotation connection of rice transplanter walking box, are provided with steering gear between steering spindle and lower box,
When being rotationally movable thereby steering spindle, its power can pass to lower box by steering gear, and then be connected to nowel
Land wheel on the land axle of body turns to, and realizes wheeled steering.But the reducing gear of rice transplanter walking box is using worm gear
Worm structure, although this reducing gear disclosure satisfy that rice transplanter carries out required gearratio during transplanting work, but worm gear
The relative sliding velocity of worm screw is big, and transmission efficiency is relatively low, and abrasion is more serious, and this structure often has the problem of insufficient strength,
Reliability is relatively low.And worm-and-wheel gear has auto-lock function, the transmission of its power be it is irreversible, i.e., can only be by worm screw band
Dynamic worm gear motion, and worm movement can not be driven by worm gear, and when the situation that the land axle for rice transplanter occur is stuck, even
The worm gear being connected on land axle can not drive worm movement, i.e., can not realize the reverse transmission of enough power, thus occur slotting
The situation that seedling machine can not be towed.Also, in lower box use worm and gear form reducing gear, worm gear it is larger, it is necessary to
The very big of the structure design of lower box, can thus make it that lower box is nearer apart from ground, rice transplanter it is poor by property.
The content of the invention
In view of the deficiency above of prior art, the present invention provide a kind of rice transplanter walking box bevel gear differential deceleration device,
Can not be by the technical problem of telephone-moving during solving rice transplanter failure, and transmission efficiency, reliability height are good by property.
In order to solve the above technical problems, the technical scheme is that：A kind of rice transplanter walking box bevel gear differential slows down
Device, it is characterised in that including：Casing, bevel gear differential reducing gear, the bevel gear differential are provided with the casing
Reducing gear drive connection is between walking output shaft and land axle.
Further, the bevel gear differential reducing gear includes composite shaft, and the composite shaft includes the defeated of order setting
Enter shaft part, differential shaft installation shaft part and output shaft part；The input shaft part is rotatablely equipped with power input bevel gear, the power
Input bevel gear is fixed on the casing；The differential shaft installation shaft part, which rotates, is fitted with differential shaft, the both ends of the differential shaft
It is connected to bevel type differential gear；The output shaft part is rotatablely equipped with double bevel wheel；One bevel type differential gear and institute
Power input bevel gear engagement is stated, another described bevel type differential gear engages with a bevel gear of the double bevel wheel, institute
Another bevel gear for stating double bevel wheel engages with land wheel shaft bevel gears, and the land wheel shaft bevel gears are connected to the land wheel
Axle.
Further, the differential shaft is arranged with the composite shaft oblique.
Further, differential shaft installation shaft part offers mounting hole, the differential shaft by bearing be rotatablely installed in
The mounting hole.
Further, the walking output shaft is connected with the composite shaft by spline housing or shaft coupling.
After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1) reducing gear uses bevel gear differential reducing gear, and the gearratio of this structure is big, compact-sized, and reliability is high, knot
Space needed for structure arrangement is smaller, has the larger radius of gyration not as worm gear, thus rice transplanter is good by property.
Moreover, compared to the reducing gear of worm and gear form, its motion is reversible.Because worm-and-wheel gear has
Auto-lock function, the transmission of its power is irreversible, i.e., worm gear motion can only be driven by worm screw, and can not drive worm screw by worm gear
Motion, and once there is rice transplanter failure, it is impossible in the case of voluntarily providing power, the worm gear being connected on land axle can not band
Dynamic worm movement, i.e., can not realize the reverse transmission of enough power, the situation that rice transplanter can not be towed just occurs.But adopt
During with bevel gear differential reducing gear, the transmission of power is realized by the engagement between conical gear, when rice transplanter because
When breaking down and the situation of power can not be voluntarily provided, the dragging rice transplanter walking of exterior power can.
2) bevel gear differential reducing gear specifically includes composite shaft, and composite shaft includes the input shaft part that order sets, differential
Axle installs shaft part and output shaft part；Input shaft part is rotatablely equipped with power input bevel gear, under power input bevel gear is fixed on
Casing；Differential shaft installation shaft part, which rotates, is fitted with differential shaft, and the both ends of differential shaft are connected to bevel type differential gear；Export shaft part
It is rotatablely equipped with double bevel wheel；One bevel type differential gear and power input bevel gear engages, another bevel type differential gear with pair
Join the bevel gear engagement of bevel gear, another bevel gear of double bevel wheel and the land wheel shaft bevel gears for being connected to land axle
Engagement.When differential shaft is arranged with composite shaft oblique, bevel gear differential reducing gear subtracts in the case where ensureing reducing gear intensity
The gearratio of fast mechanism is optimal.
