For trapezoidal blade, trapezoidal blade welding surface and secondary point of native 55 cylindrical surface of rotor are tangent.
The operation principle of the utility model combined type earth separation device and worked is further illustrated with reference to Fig. 1 and Fig. 6
Journey：Label 11 is distributed not plough soil, preceding rotary head 3 and 4 vertical direction of rear rotary head in certain centre-to-centre spacing, according to structure
Size, centre-to-centre spacing are preferably 60mm or so, and preceding rotary head 3 rotates clockwise, and corresponding preceding cutterhead cuts native region 31 in soil
Upper strata, soil of dishing out fly out along on the left of cutterhead, and rear rotary head 4 rotates counterclockwise, and corresponding rear cutterhead cuts native region 41 in soil
Earth lower floor, soil of dishing out fly out along on the right side of cutterhead.Since preceding rotary head 3 and rear rotary head 4 are there are certain centre-to-centre spacing, cause
Rotary head 4, which buries, afterwards is more than the embedded depth of preceding rotary head 3 away from earth's surface depth, because then rotary head 4 dish out soil away from
Horizontal plane angle is more than preceding rotary head 3 and dishes out the angle of soil.After preceding rotary head 3 cuts topsoil in operation process,
Dish out along left side, the constraint of premenstrual earth separation plate 2 falls into left side earth's surface after stopping, by earth separation plate before adjusting 2 and central tooth roller box outside
The angle soil in shell-side face is evenly distributed on left side 900~1000mm scopes；Rotary head 4 is outputed along preceding rotary head 3 afterwards
Secondary cutting is carried out in ditch, since soil throwing angle is big, it is necessary to pass through secondary point of 55 band of native rotor in secondary Fen Tu mechanisms 5
Move spiral-distributed multiple trapezoidal blades to dish out to rear 4 upper area of rotary head soil carry out it is secondary shed, change should
The movement locus of regional soil, by the constraint of earth separation plate behind the right side 62, makes soil be evenly distributed on right side 900~1000mm models
Enclose.Since right side is dished out soil track poor controllability, set arc plate 621 and surface plate 622 it is knockdown it is right after point soil
Plate 62, by arc plate 621 to the guide functions of soil and the reflex of surface plate 622, and arc plate 621 and surface plate
622 account for the adjustable way of 62 area ratio of earth separation plate behind the whole right side, the controllability of soil track are realized, so as to reach uniform throwing
The purpose spilt.If the soil total amount of dishing out of rotary head 4 is dished out total amount higher than the soil of preceding rotary head after during actual job,
Cause left and right railway carriage or compartment face soil covering total amount uneven, direct current generator steering can be adjusted, make rear 4 top soil of rotary head through two
Ci Fentu mechanisms 5 intervene backward left side and shed, then left side earth's surface is uniformly fallen into after being constrained via left back earth separation plate 63, to ensure two
Side throwing goes out the uniformity of soil.Installed in operation process by adjusting the left and right of two support angle steels 92 in quadrangle conditioning box 9
Position and circular disk rack 10 are in the installation site up and down and setting angle of two support angle steels 92, and earth separation plate 6 carries out together after can driving
Step section, so that rear earth separation plate 6 can adapt to the rotary speed of different soil and rear rotary head 4.
In conclusion the combined type earth separation device for rotary ditcher of the utility model, by design it is adjustable before
Combined type earth separation device afterwards, operative constraint and two is carried out to the soil dished out in rotary head operation process before and after rotary ditcher
Secondary point of soil, so that soil of dishing out can be uniformly distributed in both sides 900~1000mm scopes of rotary ditcher rotary head, shape
Into sowing railway carriage or compartment face, good kind bed environment is provided for the no-tillage seeding of cole crop and lightweight sowing.The utility model, design
Secondary earth separation device, can solve rotary head after ditching machine very well causes soil throwing angle big, difficult due to burying compared with deep
The problem of uniformly to fall into earth's surface, the front and rear earth separation plate and the rear right of adjustable arc surface and Plane Scale point of adjustable-angle
Native plate, can obtain optimal operation by adjusting relevant parameter under different soils moisture content, equipment different work speed
Effect.Application of the utility model on rotary ditcher can improve the operation effectiveness that rape gently simplifies no-tillage seeding machine, tool
There are good engineering application value and promotion prospect.
