The utility model is composed of a machine frame, a lifting mechanism and three plough body assemblies, two plough body assemblies are arranged on the main cross beam 24 of the machine frame by sliding sleeves 25, the horizontal displacement of the plough bodies can be adjusted according to the requirements of the row spacing by screw rod and screw nut mechanisms 29 and 40, the other one plough body assembly is fixedly arranged on the subsidiary cross beam 43 of the machine frame, the main cross beam and the subsidiary cross beam are parallel, the plough bodies form a staggered installation, the dragged piled phenomenon is avoided when the utility model is used, the lifting mechanism can make the plough bodies disengaged from the ground when the plough bodies travels, the utility model can carry out the operation when the plough bodies are laid down, the utility model travels along with the topographic relief, the pin shaft of a crank 9 can move freely in the elongated slot of a pull rod 10, a plough beam 53 is provided with long screw rods 34 and 42, and the penetrating angle of a ploughshare can be adjusted slightly.

Description

New-type flexible positioning plough

The utility model belongs to agricultural machinery technological field, is specifically related to the improvement of scarification equipment-plough.

The plough pattern that is driven by tractor with small four wheels is a lot of now, and the defective of its existence can reduce the following aspects: (1) beam is fixedly connected with clamp, and row spacing is adjusted inconvenience; (2) plough all is installed on the same crossbeam, and the earth and the foreign material of adjacent two plough turn ups form and drag the heap phenomenon during operation, influence operation and carry out smoothly; (3) because reasons in structure, when operation, the plough sheet can not be adjusted the degree of depth automatically, and tilling depth is inhomogeneous, unbalance stress, sometimes even damage parts.

The purpose of this utility model is, designs a kind of new-type flexible positioning plough at the defective of above-mentioned existence and makes plough apart from adjusting flexibly, and accurate positioning, plough body installation straggly avoids dragging the heap phenomenon, and tilling depth is adjustable, is convenient to operation.

The utility model is made up of frame, elevating mechanism and three groups of plough body assemblies, frame is made up of two longeron main beams and secondary crossbeam, the front end of longeron is hinged on the rear end of longeron on the left and right sides axle shaft housing of tractor and is welding main beam by U type card, the stage casing horizontal parallel of main beam is welded with secondary crossbeam, the both ends of main beam connect two groups of plough body assemblies by sliding sleeve, sliding sleeve fixedly mounts one group of plough body assembly by leading screw screw institutional adjustment horizontal displacement on the secondary crossbeam.The support of elevating mechanism is fixedly mounted on the towing plate of tractor, links to each other with main beam by chain wheel, crank connecting link and pull bar.

The plow stick of plough body assembly is installed in the cover by bolt, and cover is hinged on the beam, adjust the upper-lower position of plow stick in cover, can realize the depth adjustment of plowing, plow stick top is connected with sliding sleeve by a long bolt nut, turn nut, screw rod is flexible, can realize the fine setting of ploughshare penetrating angle.

The pull bar of elevating mechanism has elongated slot, and is hinged by pin and crank connecting link.The fluctuating of frame is freely gone here and there pin during the arable land in elongated slot.

This plough is driven by tractor with small four wheels, when walking in the field, moves crank connecting link, is stuck on the chain wheel, and the ploughshare of slinging makes it revolve sky.When arriving operating location, put down ploughshare, the rotating threaded shaft handle is transferred to row spacing ploughshare and is conformed to.By the ridge deeply requirement adjust the position of plow stick in cover, adjust the penetrating angle of ploughshare by screwing long nut, after everything is all adjusted and finishes, just can carry out ploughing work, plough body freely rises and falls according to the fluctuating on ground when operation.If one group of plough body assembly in the middle of unloading, just can realize big ridge culture industry.

The utlity model has characteristics such as rational in infrastructure, simple to operate, easy to adjust, that applicability is wide, solved simultaneously and dragged the heap problem and realize big ridge culture industry, use tractor with small four wheels to drive, suitable wide farmers is used.

Fig. 1, Fig. 2 and Fig. 3 are respectively front view of the present utility model, vertical view and left view.

Now specifically describe embodiment of the present utility model in conjunction with the accompanying drawings: the utility model is by frame (52,24,43), elevating mechanism (1,3,9,10) and plough body assembly (29,33,34,15,19,53) are formed, shown in Figure 2, frame is made up of two longerons 52, main beam 24 and secondary crossbeam 43, U type card 50 and nut 51 are fixed on shaft coupling 23 on the axle shaft housing 20 of tractor with small four wheels, one end of two longerons 52 is hinged by bearing pin 21 and shaft coupling 23, the other end of longeron and main beam 24 seam together, a secondary crossbeam 43 is welded in the stage casing of main beam 24.

Two plough body assemblies are installed in the both ends of main beam 24 by sliding sleeve 25, and sliding sleeve 25 horizontally slipping on main beam 24 relies on leading screw 29 and screw 40 to realize, adopts square thread, and self-locking property is good.Screw 40 is stuck on the main beam by U type card 26 and nut 27, and the termination of leading screw 29 combines with sliding sleeve 25 by split pin 30 and packing ring 31, and 28 is handle.Middle plough body assembly is fixed on the secondary crossbeam by U type card 44, fixed head 45 and nut 46.

Form having of plough body assembly: beam 53 (Fig. 3), plow stick 15, ploughshare 19 etc.Ploughshare 19 is fixedlyed connected with plow stick 15 by bolt 17, nut 18, pressing

plate

22, and 16 are the earth separation plate axle, shown in Figure 1,11 earth separation plates, 12 adjusting rods, 13 links, 14 hooks.Shown in Figure 2, the nut body of regulating the ploughshare penetrating angle has: long nut 34 and screw rod 42, one ends are linked to each other with sliding sleeve 25 by shaft coupling 33, bolt 32, nut 41, and the other end links to each other with side's cover 38 by shaft coupling 35, bolt 36, side's cover 38 is by the solid plow stick in bolt 37 tops, and 39 are the plough collet.

Elevating mechanism is shown in Figure 3, and support 5 is fixedlyed connected with the hitch frame 6 of tractor with small four wheels by bolt 7, and fan-shaped chain wheel 3 is fixed on the support, and connecting rod 1 and crank 9 are for being rigidly connected, and 2 is backstay, and 8 is alignment pin, and pull bar 10 cooperates with crank 9 by its elongated slot.Shown in Figure 1,47 is sliding bearing, and 4 is turning cylinder, and 48 and 49 is respectively the bearing pin of connecting rod 10 (Fig. 3) connecting crank 9 (Fig. 3) and main beam 24 (Fig. 2).
