Cylinder 6 is connected with the hydraulic oil pump of machine, is connected belt wheel 14 with the power source of machine by belt, is provided for the utility model dynamic
Power.
By controlling the zanjon of first hydraulic cylinder 1 trench digging wheel and shallow ridges trench digging wheel to move up and down, first hydraulic cylinder 1 is not
It is smaller to decline the frictional force that zanjon trench digging wheel and shallow ridges are ditched in the case of taking turns between belt and belt wheel 14 and machine power source, from
Without taking turns idle running with the zanjon trench digging wheel on moving axis 13 and shallow ridges trench digging, mechanical loss is thus reduced, adds service life,
The decline of first hydraulic cylinder 1 zanjon trench digging wheel and shallow ridges are ditched when taking turns, and zanjon trench digging wheel and shallow ridges trench digging take turns skin after being contacted with ground
Frictional force increase between band and belt wheel 14 and machine power source, zanjon trench digging wheel and shallow ridges trench digging wheel rotate, in the band of machine
Dynamic lower to move ahead, first on zanjon trench digging wheel and shallow ridges trench digging wheel, which digs knife 17 and second, digs knife 20 to needing to sow and applying fertilizer
Soil carries out ditching, control adjustment second hydraulic cylinder 6, the first bucket 11 on sheer pole 10 is put on zanjon trench digging wheel
First digs in the fertilizer ditch that knife 17 is completed, the kind cunette that the second digging knife 20 that the second bucket 12 is put on zanjon trench digging wheel is completed
In, prevent the soil that the first digging knife 17 and the second digging knife 20 are dug out from falling into fertilizer ditch and kind cunette, so as to influence fertilizer ditch and
The difficulty of the height of kind cunette, increase fertilising and sowing.
Knife 17 and second can be dug according to different requirement adjustment first and dig knife 20, rotated with spanner on the first end cap 16
Hexagonal prism 25, rotating shaft 24 are coordinated by the bumping square 28 on its other end and the square slotted eye 36 of the end face of gear 31, therefore are turned
Turn axle 24 will rotate with moving gear 31, because gear 31 engages with the teeth 32 of the outer rim of rotating disk 45, be revolved in gear 31
Rotating disk 45 can also rotate when turning, the end-face helical on the first sliding block 30 in the chute 15 of flat thread 33 and first on rotating disk 45
Coordinate, the first sliding block 30 in the first chute 15 and first thereon will be driven to dig knife 17 simultaneously while rotating disk 45 rotates
Centripetal or centrifugal motion is done, the first digging knife 17 can be thus adjusted and stretch out the length of zanjon trench digging wheel so as to controlling the depth of fertilizer ditch
It is shallow.Passing through the cooperation of the flat thread on rotating disk 45 and the end-face helical of the first sliding block 30 so that adjustment is more convenient, accurately,
The unbalance stress of the first digging knife 17 will not be caused so as to influence the service life of the first digging knife 17.
When knife 20 is dug in adjustment second, the goat's horn nut 22 on screw rod 23 is loosened, passes through fortune of the screw rod 23 in arcuate socket 38
It is dynamic that ten rib bodies 42 are rotated, when second sliding block of the rib on ten rib bodies 42 in the second chute 34 and the 3rd chute 41
When 35, it is outside more that the second digging knife 20 on the second sliding block 35 stretches out shallow ridges trench digging wheel.Second sliding block 35 is to outside shallow ridges trench digging wheel
Portion move when will extrusion spring 39, when the rib on ten rib bodies 42 away from the second chute 34 and the 3rd chute 41 second slide
During block 35, spring 39 will promote the second sliding block 35 to the center of the second housing 19.So adjustment is more convenient, accurately, equally
The unbalance stress of the second digging knife 20 will not be caused so as to influence the service life of the second digging knife 20.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
