Abstract
The utility model relates to a foldable hydraulic harrow, which comprises a front and a rear main beams 10 and 16, a main beam frame 15, a transportation working wheel 11, a lifting cylinder 14, a traction frame 9, and a main beam section composed of harrow shafts 8 and harrow pieces 7 on the front and the rear main beams 10 and 16. The utility model is characterized in that both sides of the main beam section are symmetrically provided with hydraulic foldable side beam sections and hydraulic foldable mechanisms thereof; therefore, when opened, the technology can realize wide width (reaches 7540 mm) working, and narrow width transportation can be realized after the side frames at both sides are folded. The utility model has the advantages of convenient operation, simple structure, reasonable design, multi working, high work efficiency, good quality, etc.
Description
The utility model relates to agricultural tool, particularly a kind of folding hydraulic pressure rake.
At present, the rake tool kind that farming is used is more, as old-fashioned wooden rake, only is fit to the supporting use of farm cattle.The iron rake tool that uses with tractor and for example, 1.5 meters of the fabric width deficiencies of rake, front and back two rake pipes are excessive at interval, are unfavorable for breaking ground continuously, and the traction of tired single-arm suspension, poor stability, lift adjustment is three holes only, and the latch integral elevating is entirely with operator's arm strength control depth load, the operation effort, work efficiency is lower.Chinese patent CN89217281.9 number a kind of " floods and droughts field Dual-purpose harrow " disclosed in the recent period, it is by left and right sides pull bar, connecting frame, the rake teeth pipe, the rake pin, rake teeth, draw bar, adjusting screw(rod) parts and gripper shoe are formed, though this rake has more preceding two kinds of rapid operations, resistance is little, working width reaches 1600-2100mm, work efficiency is higher, characteristics such as stability enhancing, but it still exists working width little, inefficiency to the large-scale mechanized agricultural operation of tract and the operation of tract, the no profile modeling function of raking the soil level, deficiencies such as particularly harrowing tool can not fold, and transportation is inconvenient, and the quality of raking the soil level and effect are bad.
The purpose of this utility model is: design provides a kind of reasonable in design, collapsible, be convenient to transportation, easy to operate, can realize wide cut (reaching 7540mm) operation, transportation in a narrow margin (transportation after folding) can be used for the farmland and ploughs the back hack, inserts several work such as preceding whole ground, shallow winter breaking, smooth soil moisture conservation, fallow land weed eradication, and the operating efficiency height, the measured folding hydraulic pressure rake of matter.
The utility model is achieved by following manner: a kind of folding hydraulic pressure rake, before comprising, back girder 10 and 16 reaches the girder frame 15 that is connected with it, hauling operation wheel 11 and hoist cylinder 14 and hitch frame 9 that the centre of girder frame 15 and front end are provided with respectively, and it is preceding, the girder part that the blade 7 that is provided with by 8 installations of rake axle on the back girder 10 and 16 constitutes, feature of the present utility model is: be symmetrical arranged the folding curb girder part of hydraulic pressure respectively in the both sides of girder preceding girder 10 partly, the curb girder part reaches the curb girder frame 17 that is connected with it by curb girder 1, the shape wheel 4 that spins that is provided with in the middle of the curb girder frame 17 reaches the profiling oil cylinder 13 hinged with it, by rake axle 8 blade 7 that is provided with is installed on the curb girder 1, and the hydraulic pressure fold mechanism that is provided with between the curb girder 1 on preceding girder 10 and its both sides is formed.Here curb girder 17 is former and later two, and curb girder 17 (former and later two) and curb girder frame 18 is connected by clip 17 with front and back girder 10 and 16 involutory backs.
Said hydraulic pressure fold mechanism by two bearings 3 on the girder frame 10 before being symmetricly set in and be arranged at the free bearing 5 of both sides curb girder 1 respectively and between them hinged folding hydraulic jack 2 and hydraulic pressure beam hanger 6 form, can the curb girder on girder part both sides be partially opened (as shown in Figure 2) by the hydraulic pressure fold mechanism when folding hydraulic pressure rake work rakes the soil level, if work finishes and the curb girder on both sides partly can be packed up (as shown in Figure 1), be convenient to transportation.Realizing on the folding basis of hydraulic pressure, again can be deeply by profiling oil cylinder 13 control rakes, the drag angle of present technique is 17 ° in addition, harrows dark 100-180mm, it can with the supporting use of high-power dynamic power machine.
The utility model is compared with prior art, has simple in structure, reasonable in design, can realize wide cut (reaching 7540mm) operation after opening, can realize transporting in a narrow margin after folding, and easy to operate, have simultaneously and can realize several work, high efficiency, characteristics such as quality is good.
Structure chart when Fig. 1 is the transportation of the folding back of the utility model;
Fig. 2 is that the utility model is opened the structure chart of back during operation;
Fig. 3 is the vertical view of Fig. 2.
Wherein: afterwards girders, 17 clips, 18 curb girder framves of girders, 11 hauling operations wheel, 12 folding racks, 13 profiling oil cylinders, 14 hoist cylinders, 15 girder framves, 16 before 1 curb girder, 2 folding hydraulic jacks, 3,4 contour wheels (contour wheel on the curb girder), 5 free bearings, 6 hydraulic pressure beam hangers, 7 blades, 8 rake axles, 9 hitch frames, 10.
Most preferred embodiment of the present utility model, as Figure 1-3.A kind of folding hydraulic pressure rake, before comprising, back girder 10 and 16 reaches the girder frame 15 that is connected with it, hauling operation wheel 11 and hoist cylinder 14 and hitch frame 9 that the centre of girder frame 15 and front end are provided with respectively, and it is preceding, the girder part that the blade 7 that is provided with by 8 installations of rake axle on the back girder 10 and 16 constitutes, feature of the present utility model is: be symmetrical arranged the folding curb girder part of hydraulic pressure respectively in the both sides of girder preceding girder 10 partly, the curb girder part reaches the curb girder frame 17 that is connected with it by curb girder 1, the shape wheel 4 that spins that is provided with in the middle of the curb girder frame 17 reaches the profiling oil cylinder 13 hinged with it, by rake axle 8 blade 7 that is provided with is installed on the curb girder 1, and the hydraulic pressure fold mechanism that is provided with between the curb girder 1 on preceding girder 10 and its both sides is formed.Here curb girder 17 is former and later two, and curb girder 17 (former and later two) and curb girder frame 18 is connected by clip 17 with front and back girder 10 and 16 involutory backs.
Said hydraulic pressure fold mechanism by two bearings 3 on the girder frame 10 before being symmetricly set in and be arranged at the free bearing 5 of both sides curb girder 1 respectively and between them hinged folding hydraulic jack 2 and hydraulic pressure beam hanger 6 form, can the curb girder on girder part both sides be partially opened (as shown in Figure 2) by the hydraulic pressure fold mechanism when folding hydraulic pressure rake work rakes the soil level, if work finishes and the curb girder on both sides partly can be packed up (as shown in Figure 1), be convenient to transportation.Realizing on the folding basis of hydraulic pressure, again can be deeply by profiling oil cylinder 13 control rakes, the drag angle of present technique is 17 ° in addition, harrows dark 100-180mm, it can with the supporting use of high-power dynamic power machine.
