Specific embodiment
As shown in Fig. 1 Fig. 4,
A kind of rotary tillage loosening device, including fixed axis gear case 1 and bevel gear box 12, fixed axis gear case 1 is arranged on rotary cultivator frame
Lower section, bevel gear box 12 be provided with the lower section of fixed axis gear case 1, the casing of fixed axis gear case 1 one band driving gear
17 driving gear shaft 11 and several passive tooth wheel shafts 2 with driven gear 15；Several driven gears 15 are looped around actively
Gear 17 around, and is engaged with driving gear 17 respectively, and the input shaft 13 of bevel gear box 12 is provided with active conical gear 18,
Active conical gear 18 is engaged with the driven bevel gear 16 being arranged on driving gear shaft 11, under each passive tooth wheel shaft 2
Portion is connected respectively a set of rotary tillage knife assembly, is often respectively equipped with a set of secondary support means on set rotary tillage knife assembly.
Rotary tillage knife assembly includes rotary tillage cutter shaft 9, two and buries blade 8 and two hack blades 7, and two blades 8 that bury are anti-
To the both sides being arranged on rotary tillage cutter shaft 9 lower end, and blade is down, and two hack blades 7 are tied in Double helix around rotary tillage cutter shaft 9 coiling
Structure, the top of two hack blades 7 connects through knife rest plate 19, and buried blade 8 respectively with two for the bottom of two hack blades 7
End is connected smoothly.
It is provided with, in the middle of described passive tooth wheel shaft 2 axle, the blind hole that Open Side Down, the lower end of passive tooth wheel shaft 2 is provided with mounting flange
4 and the end cap 5 that is connected with mounting flange 4, it is provided with recessed circle, on rotary tillage cutter shaft 9 axle body with the upper axis of described rotary tillage cutter shaft 9
Recessed circle is rolled with the side wall of passive tooth wheel shaft 2 blind hole by ball 3 and is connected, and ball 3 then passes through end cap 5 lower limit, described rotary tillage
It is provided with compression spring 14, when secondary support means are pressurized, rotary tillage cutter shaft 9 can be passive between the top of cutter shaft 9 and the roof of blind hole
Slide up and down in the blind hole of gear shaft 2.
Described secondary support means include gripper shoe 10 and two universal wheels 6；Rotary tillage cutter shaft 9 passes through the centre of gripper shoe 10
Weld with the axle body of rotary tillage cutter shaft 9 after through hole, gripper shoe 10 is located between end cap 5 and knife rest plate 19, and two universal wheels 6 set respectively
Put the two bottom sides in gripper shoe 10.
In order to improve the stability of rotary tillage loosening device of the present invention further, passive tooth wheel shaft 2 has three, that is, three passive
Gear 17 is engaged with driving gear 15, and the center of driven gear 17 becomes equilateral triangle arrangement, and these three driven gears
The size of axle 2 and driven gear 17 is identical；Thus, three one along the line of the other one so as to plough deeper knives are in that equilateral triangle is arranged, the driving gear of fixed axis gear case 1
17 stress are more uniform, and are not in plough-leaking phenomenon；Fixed axis gear case 1 is arranged on below frame, effectively reduces fuselage
Highly, it is extremely suitable for the operation in mountain region short tree-shaped orchard.
In order to reduce the working resistance of hack blade 7 further, triangular sawtooth is adopted to tie in the cutting edge of hack blade 7
Structure.
Under resting state of the present invention, rotary tillage knife assembly under self gravitation and compression spring 14 elastic force act on, rotary tillage cutter shaft 9
In the blind hole of passive tooth wheel shaft 2, move to lowermost end, spacing by end cap 5.
When starting operation, power is inputted by power input shaft 13, is transported to power vertical duction through bevel gear box 12
Driving gear shaft 11 in fixed axis gear case 1, makes horizontal conveyor break-in vertically be driven, and driving gear shaft 11 rotates and drives driving tooth
Wheel 17 rotation, the driven gear 15 that power is passed through to be engaged with is delivered on some passive tooth wheel shafts 2, and makes each driven gear
Axle 2 synchronous axial system, realizes the rotation of rotary tillage knife assembly.Meanwhile, under the action of gravity of fixed axis gear case 1 and bevel gear box 12,
By compression spring 14, active force is passed to rotary tillage cutter shaft 9, push down rotary tillage knife assembly so that soil cut downwards by the blade 8 that buries
Earth, moves downward, simultaneously as spring has elasticity, by rotary tillage cutter shaft 9 counteracting force, compression spring 14 is compressed, when
When rotary tillage knife assembly is down moved to universal wheel 6 and contacted with ground, universal wheel 6 starts to undertake the pressure being passed over by spring,
One only lasts for universal wheel 6 undertakes support force completely, and now, spring stress compresses, and compression in-position is that rotary tillage cutter shaft 9 is vertical
At the half of directional run.
Start to be carried forward ploughing work, hack is carried out by hack blade 7, during surface relief change, when certain rotary blade
Ground residing for assembly raises, and the universal wheel 6 on rotary tillage knife assembly experiences this change, by ground power upwards, universal
Wheel 6 gives 9 one power upwards of rotary tillage cutter shaft, so that rotary tillage cutter shaft 9 compression spring, acts on the power increase on rotary tillage cutter shaft 9,
Universal wheel 6 moment is kept and ground compression, thus keeping tilling depth at this constant.When the ground residing for certain rotary tillage knife assembly
Height reduction, the supporting role of universal wheel 6 reduces, and rotary tillage knife assembly moves downward under spring force, until universal wheel 6 is complete
Entirely undertake support force, thus keeping tilling depth at this stable.
The gripper shoe 10 that the present invention is equipped with two universal wheels 6 carries out the sensing of random road roughness and realizes tilling depth limit
System, enables rotary tillage cutter shaft 9 to slide up and down it is achieved that each group ploughs the independent self-regulated of the tilling depth of knife in the inside of passive tooth wheel shaft 2
Section function, thus ensure that orchard ground tilling depth uniformity everywhere.
Last in addition it is also necessary to it is noted that disclosed above be only the present invention specific embodiment.The ordinary skill of this area
All deformation that personnel can directly derive or associate from present disclosure, are all considered as the protection model of the present invention
Enclose.
