Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this。
As it is shown in figure 1, the deep rotary cultivator attachment of a kind of intermediate transmission, including frame 1, on-hook frame 2, change speed gear box 3, intermediate propeller shaft 4, cutter shaft joint 5, inclined seat 6, cutterhead bearing 7 and trundle 8。Crossbeam 101 middle upper part of described frame 1 is fixed with change speed gear box 3, and 3 liang of end floor beams 101 of change speed gear box are fixed with on-hook frame 2。
As shown in Figure 2, intermediate propeller shaft 4 both sides bottom change speed gear box 3 connect a cutter shaft joint 5 respectively, the other end of described cutter shaft joint 5 is respectively welded cutter and rolls 12, it is possible not only to band moving knife by the mode welded roll spin and rotate into row farming, also avoid adopting other connector to connect, thus decrease cutter roll twine grass phenomenon。Described change speed gear box 3 two bottom sides bolt respectively connects an inclined seat 6；The bottom surface of described inclined seat 6 is parallel with perpendicular, and the end face of inclined seat 6 and perpendicular acutangulate angle [alpha], and the value of α is 3-15 °, and inclined seat 6 is without top cover inner hollow disk on the whole。It is provided with power key seat 9 between described cutter shaft joint 5 front end and inclined seat 6；As it is shown on figure 3, described power key seat 9 is torus, described power key seat 9 is along the circumferential direction gone up and is uniformly offered 4-8 pin-and-hole 901；Described power key seat 9 outside wall surface has first annular groove 902 near the side of oblique cutterhead 10。Described inclined seat 6 has the second cannelure 601 near the side of oblique cutterhead 10；The inner ring of described cutterhead bearing 7 is positioned at first annular groove 902, and outer ring is positioned at the second cannelure 601, to realize the installation of cutterhead bearing 7, it is prevented that it moves axially；Described power key seat 9 place plane is parallel with the end face of inclined seat 6, and the inclination to realize oblique cutterhead 10 is installed。The front end side wall of described cutter shaft joint 5 has rectangular channel 501；It is provided with trundle 8 in described pin-and-hole 901；One end of described trundle 8 is positioned at rectangular channel 501；Owing to trundle 8 is higher with the quality of fit of rectangular channel 501, therefore the material adopted must have good processability, and namely machining deformation is little；Trundle 8 is subject to cyclic stress in transmission process, therefore its anti-fatigue performance must be fairly good, thus the material of selection trundle 8 is 20CrMnTi。One end that described trundle 8 contacts with rectangular channel 501 is hemispherical, and the linear contact lay (lower pair) of conventional pin Yu rectangular channel 501 has been become point cantact (higher pair), it is possible to make the process that in transmission process, trundle 8 swings more steady。Described rectangular channel 501 length L1With trundle 8 length L2Relation be L1>L2Sin α+2r/cos α, wherein L1For rectangular channel length, L2For trundle length, r is trundle radius, and α is sharp angle；When rectangular channel 501 is too short, trundle 8 is likely shown rectangular channel 501 and cannot be realized transmission；When rectangular channel 501 is oversize, make again beveller axial span long, thus affecting the effect of excision intermediate soil。Preferably, trundle diameter is 12mm, and length is 33mm, and rectangular channel length is 22mm。
Described power key seat 9 top bolt connects oblique cutterhead 10；On described oblique cutterhead 10, bolt connects 4-6 inclined cutter 11, and described inclined cutter 11 is uniformly distributed and opening is all towards change speed gear box 3；The end face of inclined seat 6 and the acutangulated angle [alpha] of perpendicular are 3-15 °, namely the inclined cutter 11 on oblique cutterhead 10 is made to be 3-15 ° with the acutangulated angle [alpha] of perpendicular, and adjust below intermediate propeller shaft 4 the point of a knife maximum axial distance of two inclined cutters 11 that both sides are corresponding less than 5cm, adjusting trundle with pin-and-hole gap is 0.05-0.1mm, realize inclined cutter with this and do not collide change speed gear box when turning to top, point of a knife is not collided when turning to bottom, soil bottom change speed gear box is dug up and throws both sides, by lateral dither a little, the micro-crack extension speed by cutting soil is made to accelerate, the cutting being conducive to soil destroys, reach good hack effect, meet the requirement do not balked of not backsetting, change speed gear box is made to sink, improve the rotary tillage degree of depth, realize big tilling depth。If gap is too small, then the insufficient amplitude of vibration is made to be cracked by cutting soil；If excesssive gap, then Oscillation Amplitude in transmission process can be made excessive and make transmission unstable and noise can be produced。
According to tool dimension, phase angle difference between the inclined cutter of change speed gear box both sides is 0-30 °, when phase angle is more than 30 °, the inclined cutter 11 of the right and left cuts distance between soil, the upturned soil length formed is long, does not reach good hack effect, and preferably phase angle is best when being 15 ° herein, and avoided the inclined cutter power to the cutter shaft vertical axial bending driving frequency to cutter shaft simultaneously, this will greatly reduce the vibration of machine。
Described cutter rolls and is fixed with 5-8 on 12 straight knife dish 14；Described straight knife dish 14 is fixed with 4-8 vertical cut cutter 13；The opening of adjacent straight cutting knife 13 is towards on the contrary, being arranged alternately successively。As shown in Figure 4, described cutter rolls 12 cross sections and is circular, and internal diameter is 40-80mm, and external diameter is 50-90mm, and material is No. 20 steel；Described cutter rolls and is provided with connection seat 15 outside 12 ends；Described connection seat 15 upper end is fixed on vertical beam 102 end of frame 1；Outside described connection seat 15, capping 16 is installed；Described connection seat 15 and cutter roll and are provided with cutter roller bearing between 12 and hold 17, compared with cutter directly rolling in prior art 12 and frame 1 connects, make change speed gear box 3 sink further, and then reach the purpose of deep ploughing。
Work process:
Time actually used, after being connected to tractor by on-hook frame 2, power is inputted in change speed gear box 3 by universal joint by the output power shaft of tractor, power is sent to intermediate propeller shaft 4 by change speed gear box 3, then power is sent to the cutter shaft joint 5 with its spline fitted by intermediate propeller shaft 4, trundle 8 is driven to rotate and carry out 2 α angular oscillatory motions in the rectangular channel 501 of cutter shaft joint 5, and the pin-and-hole 901 of trundle 8 traverse power key seat 9, thus power is transferred to power key seat 9, owing to power key seat 9 and oblique cutterhead 10 are fixed, and then the drift angle realizing oblique cutterhead 10 rotates, and drive the inclined cutter 11 being arranged on oblique cutterhead 10 also to do drift angle rotation, when making inclined cutter 11 forward top to, do not collide change speed gear box 3, when forwarding bottom to, the soil of change speed gear box 3 bottom right side can be dug up and thrown both sides, and then digging in the middle of realizing, gear-shifting box of rotary cultivator 3 is made to sink, increase the rotary tillage degree of depth。Cutter shaft joint 5 band moving knife rolls 12 rotations and realizes rotary tillage simultaneously。
Described embodiment be the present invention preferred embodiment; but the present invention is not limited to above-mentioned embodiment; when without departing substantially from the flesh and blood of the present invention, those skilled in the art can make any conspicuously improved, replace or modification belongs to protection scope of the present invention。
