Description

The two-way multishare plough of suspension type hydraulic turning-over mono-beam type

The utility model relates to agricultural machinery, especially is the two-way upset multishare plough of a kind of mono-beam type.

China is that agricultural is main country.In agricultural production, plough, cake, broadcast, in the production links such as intertillage, plant protection results, ploughing and weeding, to plow be first link, deep ploughing is the primary link of agricultural high yield.Over year, China is by allocating land on the household base surplus in the of nearly 20, and the shallow plowing of single plow or multishare plough has developed into current deep ploughing, the spy puts in order ground, and this is the needs of agricultural high yield.

At present, in the tractor-ploughing, a supporting light-duty turnplow or the Two-furrow plough of 195 type single cylinder tractors (hand steered, little four-wheel) arranged, more generally 50 type tractors in light-duty two ploughshares, three ploughshares or four-furrow plough, or the trailer plough of Dongfanghong-54 tractor band is ploughed ....The mounted plough of existing wheel tractor band or the pivot plow weak point when ploughing is: plow frame is a shaped as frame, plough body is arranged on the framework, just align the depth of plowing during the arable land, level, working width can not be aligned, so just, cause: 1. ploughshare can not carry out bias-adjusted with respect to the direction of advance of tractor, causes to plough when plowing less than the edge, and plough is located less than field bund " stingy "; 2. can not be by the technology status of tractor, the new and old Cheng Du of tractor, the living load size is regulated, and hangs the working width of multishare plough or upset multishare plough.

China proposes development of the West Regions, ground agricultural machinery manufacturers such as current Beijing, Tianjin, Shanghai, Luoyang are stepping up to develop the large-scale wheel tractor of producing more than 90 horsepowers, and the large-scale wheel tractor more than 100 horsepowers increases by force from the external introduction impetus in recent years simultaneously.But supporting with it farm machinery seldom, and especially structure advanced person's multishare plough just still less.For this reason I specialize in and produced with wheel tractor supporting, with supporting suspension type multishare plough, the two-way multishare plough of suspension type hydraulic turning-over mono-beam type (2,3,4,5 turnplow) of high-power wheel tractor.This mono-beam type multishare plough has plough is carried out bias-adjusted, and working width is regulated, and also has the standard package of only beam and the breaker bolt of single mouldboard plow and protects structures such as structure, two station fork type hydraulicdirectional control valves.These novel structures are declared utility model patent respectively.

The purpose of this utility model is to overcome the weak point in the above prior art, and the plough body bias-adjusted structure of its mono-beam type multiplow Dan Li, the working width adjustment structure of plough are provided.

Formation of the present utility model:

The plough body bias-adjusted structure (referring to Fig. 2, Fig. 3) of the two-way upset multishare plough of this mono-beam type:

Bias structure mainly is by trapezoidal nut 20, regulates the central convex connection in groove follower connecting plate 7, the connection front and back slide block 8 on trapezoidal screw 21, the main shaft, plough body u shape contiguous block 9, and only beam 10 several big parts are formed.Solely on the beam 10 all moldboard plow bottom is installed.

It is the heavy load operation that mouldboard plow is ploughed, and at the tractive force of tractor when not being very big, the working width of plough is often less than the Track width of tractor.Like this, near ridge, enclosure wall, irrigation canals and ditches or hedge the time, always plough, stay the uncultivated land band of a 30-50cm, lose many arable areas less than the limit.The offset plough body structure can be offset certain distance to side with respect to tractor, tractor wheels can't can be ploughed in close place fully.Referring to Fig. 2, Fig. 3, whole plough body is traversing to the front direction, i.e. laterally moving to tractor unit direction of advance.

The off-set construction of offset plough is to adopt traversing mode, (referring to Fig. 2, Fig. 3).When trapezoidal screw 21 was regulated in rotation, convex slide block 8 can laterally move on spill slide block 7 back and forth.Because central convex slide block 8 back are connecting solely beam 10, therefore solely beam 10 has also just played the bias-adjusted effect, as Fig. 2, Fig. 3 form also just along with convex slide block 8 laterally moves.As long as in the direction of the clock rotation regulate trapezoidal screw 21 only beams 10 will be traversing to the arrow direction, can tractor wheels lean on less than the place plough.

Working width (working width) adjustment structure of the two-way upset multishare plough of this mono-beam type: (referring to Fig. 4 structure)

The modulation structure of plough is to be made of central convex slide block 8, front and back bearing A, G, left-handed screw B, left-handed nut plate C, plough body u shape contiguous block 9, main regulation screw rod D, right-handed nut's plate E, right handed screw F, big bearing pin H before and after connecting.

The plough in past is that its working width is fixing after being made by factory, can not change working width width degree during use, can't adapt to the arable land of the tractor and the different soils of different traction powers.At this situation, this " the solely beam " of my development and production can the only beam of beat (main cant beam) setting angle can adjust the working width (working width) of two-way pivot plow, can be good at cooperating the tractor-drawn watt level to differ, wheelspan is wide, narrow differing and different soils.Narrow when tractor-drawn underpower, wheelspan, can turn down working width (working width) when soil is hard, as shown in Figure 4, can rotate main regulation screw rod D, allow the α angle diminish.At this moment, total working width of plough also can reduce.Otherwise, transfer big α angle, total working width becomes big.The α angle is exactly the horizontal angle between unit direction of advance and the only beam.

During adjustment, mainly be to insert in the interstitial hole of homophony pole D with an iron staff, carry out left rotation and right rotation, solely beam 10 will rotate the size that changes the α angle around big bearing pin H.At this moment working width reaches in the time of working smoothly, two nutplate C about locking, and E, the working width of multishare plough is regulated and is finished.

This suspension type hydraulic turning-over, the two-way multishare plough of mono-beam type, mainly by with the suspension plow frame 3 that is provided with the hydraulic lifting system tractor, plow frame on oil cylinder 5, two station fork type hydraulicdirectional control valves 4, a plurality of moldboard plow bottom constitute.

This multishare plough is provided with plough body bias-adjusted structure, structure is made of trapezoidal nut 20, accent trapezoidal screw 21, groove follower connecting plate 7, central convex connection slide block 8, plough body u shape contiguous block 9, only beam 10, when rotating screw bolt 21, slide block 8 can laterally move on slide block 7 back and forth, and slide block 8 back are connecting solely beam 10, and solely the multishare plough of installing on the beam 10 is also along with slide block 8 laterally moves;

Also be provided with the working width adjustment structure of multishare plough on this multishare plough, structure connects slide block 8, front and back bearing A by central convex before and after connecting, G, left-handed screw B, left-handed nut plate c, plough body u shape contiguous block 9, main regulation screw rod D, right-handed nut's plate E, right handed screw F, big bearing pin H constitute, front and back bearing A, G are separately positioned on slide block 8, the only beam 10, during levelling, solely beam 10 can rotate in right amount and forms the α angle with the tractor direction of advance around big bearing pin H.

The working width adjustment structure of said plough is stepless levelling, formed α angle during levelling, and the working width that the increase of α angle is then ploughed is with regard to corresponding increase, and the working width that the α angle reduces then to plough is corresponding to be reduced.

Good effect of the present utility model:

1. the bias-adjusted structure of plough body can be offset certain distance (about 30cm) to turnplow formula plough with respect to tractor to side, tractor wheels can't can be ploughed in close place fully.

2. multishare plough working width adjustment structure is stepless levelling, it is the working width (it is constant to protect special tilling depth) of technology status, tractive force size, soil specific resistance and the next stepless levelling plough of hard degree size thereof of visual tractor, during the adjustment structure levelling, the α angle that constitutes between only beam on formed tractor direction of advance and the plow frame, the α angle increases, then the working width of plough increases, and the working width that the α angle reduces then to plough reduces.

3. above-mentioned 1.2 described adjustment structures, reasonable in design, levelling is convenient.
