Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Referring to Fig. 1, Fig. 2 and Fig. 5, the utility model spiral plough, comprise frame 3, be arranged on the engine 1 of upper rack and be arranged on the decelerator 2 under frame lower engine, be provided with arc 4 at frame 3 lower surfaces, arc 4 middle parts are recessed so that decelerator 2 is covered, and arc 4 both sides are bent to form arc guide surface (arc plate structure is shown in Fig. 3) obliquely.One vertical screw auger 5 links are connected with decelerator 2 through arc 4, and screw auger 5 is under decelerator 2, and engine 1 drives screw auger 5 to rotate after slowing down by decelerator 2.Be provided with some native cuttves 6 of cutting at the marginating compartment of screw auger 5 helicoids, it is adjustable in the radial position of screw auger helicoid that this cuts native cutter 6.Be provided with disk pawl 7 in screw auger 5 bottoms, the each claw of disk pawl 7 has face cutting edge A and periphery cutting edge B, and disk pawl structure is shown in Fig. 6.When rotated, face cutting edge A cuts ditch bottom surface, guarantees the smooth of bottom of trench; The periphery cutting edge B of disk pawl cuts the soil on circumference.Be provided with the mud guard 8 that can spin upside down at frame 3 afterbodys by hinge 10, between frame 3 and mud guard 8, be provided with extension spring 12.The power of engine 1 drives screw auger 5 to rotate after decelerator 2 slows down.Risen by screw auger 5 through cutting the soil that native cutter 6 cuts, under the effect of arc 4, throw to both sides.
The effect of mud guard 8 is not allow earth retroject.Its concrete structure can be referring to Fig. 4, and mud guard 8 is up big and down small trapezoidal flat board, and shape is consistent with the native face of cutting of screw auger 5, can be to trench digging shaping operation.The side wing 9 of mud guard 8 oriented side front, both sides, top bendings, side wing 9 can be scraped the earth of limes marginis at a distance; Mud guard 8 bottoms bend forward, and earth is difficult for leaking from bottom of trench.
Referring to Fig. 8, described screw auger 5 adopts double helix face, cuts native cutter 6 and install one every 90 ° on same helicoid, and a helicoid is four, on two helicoids, cuts the 45 ° of installations of staggering of native cutter.Generally speaking on the circumference of screw auger 5, there is one to cut native cutter 6 every 45 °, amount to eight.
Cut native cutter 6 and be connected with screw auger 5 use nuts, cut native cutter 6 and adopt manganese steel to make.Referring to Fig. 7, cutting native cutter 6 has certain windup-degree with the installed surface of spiral-poker 5 with the upper plane of the cutting edge of cutting native cutter, and windup-degree equals the helical angle of screw auger, in the course of the work, and the upper plane level all the time of cutting edge.
Because earth after trench digging is larger to the resistance of mud guard, iff relying on tension spring tension, be also not enough to maintain mud guard and normally keep off mud state, powerful resistance can overcome extension spring power overturns mud guard backward.Based on this, the utility model is provided with two jacks in frame 3, mud guard upper end is provided with two horizontal journal stirrups, referring to Fig. 4, on two journal stirrups, be respectively provided with the lockhole D corresponding with jack position, a U-shaped handle 11 that Open Side Down inserts lockhole on jack and the mud guard journal stirrup in frame so that frame 3 and mud guard 8 are reinforced the connection simultaneously.11 structures of shaking hands are shown in Figure 10, and handle openend forms pin C.
Further, in order to guarantee to bury smoothly, described screw auger 5 bottoms are conical.Simultaneously smooth in order to guarantee bottom of trench, the face cutting edge A of disk pawl is lower than the conical tip of screw auger bottom.
The outstanding power demand of this plough is little, can directly hang over small tractor rear portion.When concrete operation, in the time that plough screw auger 5 buries, tractor does not travel forward, pull-up handle 11, and by mud guard 8, toward top upset, extension spring 12 makes mud guard 8 fixing, as shown in Figure 9.After burying completely, output a bit of irrigation canals and ditches, then mud guard 8 is down overturn, the shake hands pin C of 11 bottoms inserts in the lockhole D on mud guard 8 tops, thereby realizes being fixedly connected with of frame 3 and mud guard 8, as shown in Figure 1, even if resistance is very large, mud guard also can not overturn backward.Now small tractor can be walked forward, and facility start ditching operation.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
