Wherein:Fixed axis gear case 1, passive tooth wheel shaft 2, ball 3, mounting flange 4, end cap 5, universal wheel 6, hack blade 7, Bury blade 8, rotary knife axis 9, support plate 10, driving gear shaft 11, bevel gear box 12, input shaft 13, compression spring 14, passively Gear 15, driven bevel gear 16, driving gear 17, active conical gear 18, knife rest plate 19.
Specific implementation mode
Such as Fig. 1 --- shown in 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 are arranged in rotary cultivator The lower section of rack, bevel gear box 12 are set to the lower section of fixed axis gear case 1, set that there are one bands in the babinet of fixed axis gear case 1 actively The driving gear shaft 11 of gear 17 and several passive tooth wheel shafts 2 with driven gear 15;Several driven gears 15 are looped around It around driving gear 17, and is engaged respectively with driving gear 17, the input shaft 13 of bevel gear box 12 is equipped with active circular cone tooth Wheel 18, active conical gear 18 are engaged with the driven bevel gear 16 on driving gear shaft 11, each passive tooth wheel shaft 2 Lower part be connected respectively a set of rotary tillage knife assembly, often cover rotary tillage knife assembly on be respectively equipped with a set of secondary support means.
Rotary tillage knife assembly includes that rotary knife axis 9, two buries blade 8 and two hack blades 7, and two blades 8 that bury are anti- To the both sides mounted on 9 lower end of rotary knife axis, and blade is downward, and two hack blades 7 are in double helix knot around the coiling of rotary knife axis 9 Structure, the top of two hack blades 7 are connected through knife rest plate 19, and bury with two blade 8 respectively for the lower parts of two hack blades 7 End is connected smoothly.
The blind hole that Open Side Down is equipped among 2 axis of passive tooth wheel shaft, the lower end of passive tooth wheel shaft 2 is equipped with mounting flange 4 and the end cap 5 that is connect with mounting flange 4, recessed circle is equipped with the upper axis of the rotary knife axis 9, on 9 axle body of rotary knife axis Recessed circle is rolled by the side wall of ball 3 and 2 blind hole of passive tooth wheel shaft and is connected, and ball 3 then passes through 5 lower limit of end cap, the rotary tillage Compression spring 14 is equipped between the top of cutter shaft 9 and the roof of blind hole, rotary knife axis 9 can be passive when secondary support means are pressurized It is slided up and down in the blind hole of gear shaft 2.
The secondary support means include support plate 10 and two universal wheels 6;Rotary knife axis 9 passes through the centre of support plate 10 It is welded with the axle body of rotary knife axis 9 after through-hole, between end cap 5 and knife rest plate 19, two universal wheels 6 are set support plate 10 respectively Set the two bottom sides in support plate 10.
In order to further increase the stability of rotary tillage loosening device of the present invention, there are three passive tooth wheel shafts 2, i.e., three passive Gear 17 is engaged with driving gear 15, and the center of driven gear 17 is arranged at equilateral triangle, and these three driven gears The size of axis 2 and driven gear 17 is identical;Three sets of coulter arrangements in equilateral triangle as a result, 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 mounted below rack, effectively reduces fuselage Highly, it is extremely suitable for the operation in the short tree-shaped orchard in mountainous region.
In order to further decrease the working resistance of hack blade 7, triangular sawtooth knot is used in the cutting edge of hack blade 7 Structure.
Under stationary state of the present invention, rotary tillage knife assembly is under its own gravity and the effect of 14 elastic force of compression spring, rotary knife axis 9 In the blind hole of passive tooth wheel shaft 2, it is moved to lowermost end, is limited by end cap 5.
When starting operation, power is inputted by power input shaft 13, is transported to power vertical duction by bevel gear box 12 Driving gear shaft 11 in fixed axis gear case 1, makes horizontal conveyor deflecting be driven vertically, and the rotation of driving gear shaft 11 drives driving tooth 17 rotation of wheel, power is transmitted to by the driven gear 15 being engaged on several passive tooth wheel shafts 2, and make each driven gear Axis 2 rotates synchronously, and realizes the rotation of rotary tillage knife assembly.Meanwhile under the gravity of fixed axis gear case 1 and bevel gear box 12, By compression spring 14, active force is passed into rotary knife axis 9, pushes down rotary tillage knife assembly so that incision is native downwards for the blade 8 that buries Earth moves downward, simultaneously as spring has elasticity, by 9 reaction force of rotary knife axis, compression spring 14 is compressed, when Rotary tillage knife assembly moves to universal wheel 6 when being contacted with ground down, and universal wheel 6 starts to undertake the pressure passed over by spring, One only lasts for undertaking support force completely to universal wheel 6, at this point, spring stress compresses, compression in-position is that rotary knife axis 9 is vertical At the half of directional run.
Start to be carried forward ploughing work, hack is carried out by hack blade 7, when surface relief changes, when some rotary blade Ground residing for component increases, and the universal wheel 6 on rotary tillage knife assembly experiences this variation, universal by the power that ground faces upward Wheel 6 gives 9 one upward power of rotary knife axis, and to make 9 compressed spring of rotary knife axis, the power acted on rotary knife axis 9 increases, So that 6 moment of universal wheel keeps compressing with ground, to keep tilling depth at this constant.When the ground residing for some rotary tillage knife assembly Height reduces, and the supporting role of universal wheel 6 reduces, and rotary tillage knife assembly moves downward under spring force, until universal wheel 6 is complete Support force is undertaken entirely, to keep tilling depth at this to stablize.
The support plate 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 knife axis 9 to be slided up and down in the inside of passive tooth wheel shaft 2, realizes the independent self-regulated of the tilling depth of each group coulter Function is saved, to ensure that the tilling depth uniformity of orchard ground everywhere.
Finally, it should also be noted that it is disclosed above be only specific embodiments of the present invention.The ordinary skill of this field All deformations that personnel directly can export or associate from present disclosure are considered as the protection model of the present invention It encloses.
