Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description.
The utility model has adopted the design of unique single-beam, promptly hitch frame 1, left side rake frame 9, right rake frame 10 and axle stand 19 all are connected on the girder frame 11, and such global design has better realized wide cut operation, the function that shifts of transportation in a narrow margin.Hitch frame 1 is connected on the girder frame 11 through hitch frame connecting pin 4, and is connected with levelling gear 3, and levelling gear 3 one ends are connected on the hitch frame 1 by connecting pin 2, and the other end adopts dual spring 21 to be connected with girder frame 11, alleviates the rigid shock to the utility model.Left side rake frame 9 is harrowed frame 10 is connected to girder frame 11 through rake frame connecting pin 5 the left and right sides with the right side; Make it symmetric arrays, and be connected with flap oil cylinder 13, flap oil cylinder 13 1 ends are connected with right rake frame 10 with left side rake frame 9 through oil cylinder connecting pin A12; The other end is connected with girder frame 11 through oil cylinder connecting pin A12; Through the flexible expansion and the flap of realizing left side rake frame 9 and right rake frame 10 of flap oil cylinder 13, will be behind the flap safety device 6 lockings, to guarantee to transport safely transfer.Left front rake group 7, right front rake group 8, left back rake group 14 and right back rake group 15 are fixed on left side rake frame 9 and the right rake frame 10 through rake group connecting bolt 16; Forward and backward rake group dislocation is arranged and four groups of rake groups are the whole symmetric arrays of X-shaped in girder frame 11 both sides, and the angle of regulating forward and backward rake group can realize the adjusting of working depth.Axle stand 19 is connected with girder frame 11 through wheel shaft stand 23, and is connected with hoist cylinder 17, and wheel shaft stand 23 is fixed on the girder frame 11 through wheel shaft stand connecting bolt 22; Hoist cylinder 17 1 ends are connected with girder frame 11 through oil cylinder connecting pin A12; The other end is connected with axle stand 19 through oil cylinder connecting pin B18, and when hoist cylinder 17 elongations, axle stand 19 descends; The rake group road clearance is strengthened, at this moment can harrow the flap or the expansion of frame; When the hoist cylinder contraction, axle stand rises, and the rake group road clearance reduces, and at this moment can transport and shift or plough rake work.Tire 20 is installed in the wheel shaft installing hole of axle stand 19, and bolt is arranged, and the utility model tire adopts roomy, heavy rubber tyre, and it is safer stable that transportation is shifted.The hydraulic circuit of the utility model all adopts high pressure resistant oil pipe and spherical interface, and arranged distribution is reasonable, makes easy for installation, quick, safe in utilization stable.
It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
