Figure 40 is the exploded perspective view of rotary tillage apparatus structure.Rotating shaft 415, its cross section is shaped as regular hexagon.Rotary tillage tine 416 is made of base portion 420 and claw 421.The front view (Figure 41 (a)) and the end view (Figure 41 (b)) that in Figure 41, have shown rotary tillage tine 416, be provided with the embedded hole 423 chimeric with rotating shaft 415 at the central portion of base portion 420, the circumference on the basic regular hexagon summit with connection rotating shaft 415 cross sectional shapes of the shape of embedded hole 423 is consistent.In addition, on base portion 420, around embedded hole 423, be provided with three slotted holes 422, each slotted hole 422, be along circumference that to be the center with the axle center of rotating shaft 415 drawn with the radius of regulation, have Rack circular-arc.In addition, the shape of each slotted hole 422 is identical and 120 degree that stagger.Claw 421, with base portion 420 be one, be to the top of base portion 420 extend tabular, the crooked and plough portion when forming ploughing and weeding of its leading section.The both sides of the edge of claw 421 form blade, and when ploughing and during contrary ploughing, blade contact also cutting is ploughed.Profile beyond the claw of base portion 420, its incorporate part, the axle center that forms with rotating shaft 415 is a central circular.
As shown in figure 40, in the both sides of rotary tillage tine 416, rotatable parts 424 are entrenched on the rotating shaft 415, and when mounted with base portion 420 close installation of rotary tillage tine 416.As shown in figure 42, rotatable parts 424 are provided with the shape installing hole consistent with the regular hexagon of the cross sectional shape of rotating shaft 415 427 at central portion.Around installing hole 427, be provided with three hole portions 426, and each hole portion 426, be the shape that can insert the rod-like members 428 of strip described later.In addition, each hole portion 426 when mounted is in the face of each slotted hole 422 ground of rotary tillage tine 416 120 degree that stagger.The excircle of rotatable parts 424, be circular essentially identical discoideus with rotary tillage tine 416 base portions 420, and with the abutment surfaces of rotary tillage tine 416 base portions 420 be the plane, but on the face opposite, form the flange portion 425 of the circular concentric littler than excircle with abutment surfaces.
When installing on rotating shaft 415, in 424 groups of the rotatable parts of rotary tillage tine 416 both sides, as a unit a plurality of units are installed, setting-in sleeve 417 is to keep the interval of regulation between constituent parts with close installation.Sleeve 417, its two ends are embedded on the flange portion 425 of rotatable parts 424, and with this as fixing.The rod-like members 428 of 3 strips runs through the slotted hole 422 corresponding to the rotary tillage tine 416 of the hole portion 426 of the rotatable parts 424 of constituent parts respectively.Each rod-like members 428 is bolt shape, at one end forms head, forms screw thread at the other end.Run through the hole portion 426 that is positioned at outermost rotatable parts 424 and on the screw thread that comes out the spinning nut, rotary tillage tine 416, rotatable parts 424 and sleeve 417 closely are fixed together.
As above-mentioned institute, the rotary tillage tine of installing 416, because the shape of its embedded hole 423 and the circumference basically identical on the regular hexagon summit that is connected rotating shaft 415 cross sectional shapes, so can rotate flexibly around rotating shaft 415, but because rod-like members 428 is moved about in the slotted hole 422 that is entrenched in base portion 420, so as shown in figure 43, be subjected to the restriction of rod-like members 428 and can only rotate the circular-arc length of slotted hole 422 flexibly.In addition, because the installing hole 427 of rotatable parts 424 is regular hexagons identical with the cross sectional shape of rotating shaft 415, so rotatable parts 424 are with rotating shaft 415 rotation, and are rotated the rod-like members 428 that the hole portion 426 of parts 424 keeps and also rotate simultaneously with rotatable parts 424.Thereby rotary tillage tine 416 is engaged in the end of slotted hole 422 with rod-like members 428 and rotates around rotating shaft 415.When rotary tillage tine 416 contacts around rotating shaft 415 rotations and with the arable land, as mentioned above, owing to can only rotate the length part of slotted hole 422 circular arcs flexibly, so it is pushed and ploughs and in case to counter-rotation, then rod-like members 428 just with the end of slotted hole 422 mutually by and transmit the rotatory force of rotating shaft 415 and cut the arable land.Owing in when ploughing and during contrary ploughing, all do same action under the situation arbitrarily, so the claw 421 that at any time can reduce rotary tillage tine 416 at the resistance that is pressed into when ploughing, and also can not concentrate on load the leading section of claw 421.
To the claw 421 of the rotary tillage tine 416 of constituent parts, as shown in figure 44, the mode that slotted hole 422 is embedded in moving about on each rod-like members 428 is installed from axially seeing every 120 degree of rotating shaft 415 with staggering.From integral body, claw 421 shape ground is in the shape of a spiral arranged, if rotate rotating shaft 415 with this installment state, then because each claw 421 can sequentially be pressed into the arable land, so the resistance can reduce claw 421 and be pressed into the time and can carry out farming more efficiently with fraction horsepower.
In above-mentioned example, explanation be with three pawls with stagger 3 screw types of 120 degree of portion 421, but if rotary tillage tine is dwindled the angle that staggers and forms helical form, then the rotary tillage tine angle of rotating flexibly just diminishes.At this, the example of intactly keeping the flexible angle of rotating of rotary tillage tine and dwindling the angle landform curl that staggers is described.
Exploded perspective view when Figure 45 is 6 spirals.Rotary tillage tine 416, support board 433 and sleeve 417 are entrenched on the back shaft 429 with regular hexagon cross sectional shape.Back shaft 429 is tubular, and in end, the prolongation of rotating shaft 415 columned insertion section 430 is set, and insertion section 430 is inserted a side end of back shafts 429 and used rotating shaft 415 rotary axis of earth supporting back shaft 429 flexibly with this.On the base portion 420 of rotary tillage tine 416, be provided with embedded hole 431 with the regular hexagon of the cross sectional shape basically identical of back shaft 429 at central portion, and to be provided with along the axle center with back shaft 429 be stagger 6 locating holes 432 of 60 degree of the circumference in the center of circle around it.On support board 433, offered the regular hexagon through hole 435 with the cross sectional shape basically identical of back shaft 429, and be provided with around it be positioned at above-mentioned locating hole 432 same circumference on the hole portions 434 of 120 degree that stagger.The excircle of support board 433, be round-shaped essentially identical discoideus with the base portion 420 of rotary tillage tine 416, and with the abutment surfaces of rotary tillage tine 416 base portions 420 be the plane, but on the face opposite, form the flange portion 436 of the circular concentric littler than excircle with abutment surfaces.
Support board 433 closely is installed in from both sides on rotary tillage tine 416 base portions 420, and with three hole portions 434 of support board 433, consistently installs with selected three locating holes 432 on 6 locating holes 432 of base portion 420.In addition, with a rotary tillage tine 416 and two support boards 433 as a unit ground chimeric a plurality of units on back shaft 429.If the claw 412 of the rotary tillage tine 416 of constituent parts is chimeric with respect to the back shaft 429 60 degree ground that stagger, then can be mounted to the helical form of axially seeing as shown in figure 46 from back shaft 429.In addition, setting-in sleeve 417 between constituent parts, and with the two ends of sleeve 417 and the flange portion 436 chimeric intervals to keep stipulating of support board 433.
In the locating hole 432 of the base portion 420 of three hole portions 434 of the support board 433 of constituent parts and the rotary tillage tine 416 consistent, pass the support bar 448 of 3 strips that supporting abreast with back shaft 429 with it.Head at each support bar 448 1 ends formation bolt forms screw thread at the other end.End in rotating shaft 415 sides of back shaft 429 is entrenched in case member 445 on the back shaft 429 in outermost.Case member 445 is for round-shaped and be the parts that are used to cover action component 437 described later.In addition, portion has the regular hexagon through hole 447 with the cross sectional shape basically identical of back shaft 429 in the central, and has three hole portions 446 that connect above-mentioned 3 support bars 448 around through hole 447.
One side's rotating shaft 415, its cross sectional shape are regular hexagon, are formed as described above insertion section 430 and axle supporting back shaft 429 in the end.In addition, discoideus action component 437 and rotatable parts 441 are entrenched on the rotating shaft 415.Action component 437 has the embedded hole 439 chimeric with rotating shaft 415 at central portion, and embedded hole 439 is the shape of the circumference basically identical on the regular hexagon summit that connects rotating shaft 415 cross sectional shapes.Thereby action component 437 can rotate flexibly around rotating shaft 415.In addition, around embedded hole 439, have three slotted holes 438, being shaped as along the circumference that is the center with the axle center of rotating shaft 415, is drawn with the radius of regulation and having the circular-arc of Rack of each slotted hole 438.In addition, the shape of each slotted hole 438 is identical and 120 degree that stagger.Between each slotted hole 438 and embedded hole 439, have and be used for screwing togather respectively three screws 440 that fixedly are formed at above-mentioned 3 support bar 448 end thread.
