Description
The invention belongs to the farm implements of soil tilth, more particularly belong to can be in advancing the turn over plough of soil layer of the formula of working at shuttles on both sides.
Plough made in accordance with the present invention can be suspended on supporting use on the tractor when having enough greatly the operation width.
The plough of existing similar function is pressed textural classification usually, and wherein each all has certain advantage.But the plough-body spacing of the decision of all these ploughs plough length has all surpassed permissible value, in this permissible value, can guarantee the length dimension minimum of plough, does not influence the work of plough simultaneously again, does not particularly hinder native sheet to pass through between plough body.
Reversible plow is well-known, the most universal, it comprises bearing support, and the reversing frame with respect to longitudinal axis deflection is installed on bearing support, turns over right deep-tillage bottom, skin coulter and colter and is fixed on plough bed on the plough body with respect to the horizontal plane being fixed with a left side on the reversing frame symmetrically.
The difference of the common plough that reversible plow and single face (the normally right side) are turned over, only be that reversible plow has reversing frame and two operating mechanism of overlapping, the length of their decision reversible plows, and the complete structure with common one way plough with the mutual alignment of its structure is consistent with the mutual alignment, and the one way plough plough-body spacing is decided by the existence of skin coulter, in the effect of the skin coulter spacious ditch that to be the soil layer top throwing that will downcut leave to the front plough body.
Pair cover operating mechanism of reversible plow is the shortcoming of this plough, the technical measures of this shortcoming therefore occurred overcoming.
Rotating support in horizontal plane is installed on the bearing support of a kind of plough that can overcome the reversible plow shortcoming, is fixing plough body on this support, each plough body can guarantee that all soil layer turns over to the left and right sides.
The plough body of this plough has two kinds of patterns.
A kind of plough body of pattern has with the mouldboard of turning over about two ploughshares unified, and the front tip of ploughshare cooperatively interacts according to the plough road or separately.Soil layer reverses direction as requested should be installed mouldboard with articulated joint from the left side or the right of plow standard, and the axle of articulated joint is positioned at the intersection of plow standard symmetry vertical plane and mouldboard symmetrical plane.
The shortcoming of this plough body is that mouldboard increases in the straight-line dimension of vertical direction, therefore is difficult to accomplish that the working width of plough body is very wide.In addition, mouldboard shape (cylindricality or taper) can not be suitable for working under any soil condition.
The plough body of another kind of pattern is better.This is a kind of combined type plough body, and each plough body comprises around the rotating front and back of vertical axis symmetric part, and they are used for turning over soil layer respectively left and to the right.
A kind of plough body is for example arranged, on its anterior plow standard, be fixed with the band ploughshare left and the mouldboard forward part of turning over to the right, their operating position is with respect to the vertical transverse plane mirror-symmetrical by the plow standard rotating shaft, and the rear portion of plough body itself is the concave cylindrical body that can rotate while still alive.
The shortening type is made by the rear portion of this plough body system, thereby this is also to reduce the length of ploughing in order to reduce plough-body spacing, but so when plough body work the soil layer upset in poor shape, that is to say to make the quality reduction of turning over.
Also has a kind of plough body, on its anterior plow standard, be fixed with the mouldboard forward part of turning over of the unification of band ploughshare left and to the right, this mouldboard forward part is symmetrical with respect to the plane by plow standard rotating shaft and ploughshare center, and fixing the rear portion of turning over mouldboard left and to the right on the rear portion of plough body, this mouldboard rear portion of turning over left and to the right is that mutual mirror-symmetrical ground is installed.Soil layer reverses direction as requested, the front and rear part deflection state of plough body should guarantee that a side of mouldboard front portion docks with the side at corresponding mouldboard rear portion when reversing frame is in the relevant position, therefore form the complete mouldboard (US, A, 3305025) of the soil layer of turning over to the left or to the right.
This plough body can satisfy any requirement relevant with finishing the technical process of turning over.But, if on the known plough that has the horizontal plane reversing frame, use this plough body, then reduce to plough the value that condition that length can not rely on plough-body spacing to be reduced to only to be passed through by native sheet between plough body decides, that is to say the permissible value that is reduced to by simple faming technology requirement decision.
Reason is that the reversing frame that is contained on the bearing support of this plough can only be with respect to vertical fore-and-aft plane to the same angle of two edge run-outs, thereby turning to of plough body rear portion can be simple because structural requirement limits reducing of plough-body spacing when reversing frame is in the operating position, and said structural requirement is meant not turning to of plough body rear portion contacted with the plough body of back.Because adopt skin coulter and colter also can further increase the length of plough.
Therefore, the plough that has the horizontal plane reversing frame only has a cover operating mechanism, see that from the viewpoint of saving material it is more superior than reversible plow, but owing to must guarantee by each plough body soil layer of alternately turning over round about, the structure of plough body becomes complicated, and needs the transmission mechanism that makes plough body adjust to the operating position.
Although it is also promising concerning the plough manufacturing industry to have the plough of horizontal plane reversing frame, but because the shortcoming relevant, can not keep the existing parameter constant of plough body and adopt solution under the condition of skin coulter and colter to reduce to plough the problem of length thereon with the reversing frame mechanism of this plough.
Reversing frame is not only the critical defect of above-mentioned plough with respect to vertical fore-and-aft plane to the same angle of two edge run-outs, and is the critical defect (no matter its plough body pattern how) of all known ploughs of band horizontal plane reversing frame.Just because of this shortcoming, just can not reduce the plough-body spacing of above-mentioned plough and the plough of the littler length of manufacturing.
The objective of the invention is to overcome above-mentioned shortcoming.
Basic task of the present invention is to develop a kind of like this plough, and the support of this plough and operating mechanism's motion mode should be able to be by reaching the purpose that reduces to plough length at a distance of the method for more closely arranging plough body.
The method that solves the task of putting forward is, plough comprises bearing support, horizontal plane reversing frame and the operating mechanism that is fixed on the reversing frame are being installed on the bearing support, operating mechanism comprises that a left side turns over and right deep-tillage bottom, according to invention, reversing frame can be with respect to the vertical transverse plane of passing through the reversing frame rotating shaft to the same angle of two edge run-outs by installing.
According to one of structural shape of ploughing, its each plough body is made up of preceding rotating part and rear portion, before be fixed with on the rotating part band ploughshare, with the mouldboard part of plane symmetry by gyroaxis and ploughshare center, being fixed with a left side of installing on mutual mirror-symmetrical ground on the plough body rear portion turns over and the right side mouldboard part of turning over, according to invention, the ψ angle can be rotated to both sides by the vertical plane perpendicular to reversing frame in each plough body rear portion after installation, this ψ=α-γ is in the formula
The necessary corner in operating position is adjusted at ψ-plough body rear portion;
α-be in the reversing frame longitudinal axis and the interplanar angle of vertical transverse of operating position;
Angle between the plough body rear portion symmetrical plane of γ-be in operating position and vertical fore-and-aft plane.
Another kind of structural shape according to plough, its each plough body is made up of preceding rotating part and rear portion, before be fixed with on the rotating part band ploughshare, with the mouldboard part of plane symmetry by gyroaxis and ploughshare center, being fixed with a left side of installing on mutual mirror-symmetrical ground on the plough body rear portion turns over and the right side mouldboard part of turning over, according to invention, each plough body rear portion is rigidly fixed on the reversing frame.
The side edge limit of each ploughshare preferably with the direction of motion of plough at an angle, and want sharpening.
The side of the anterior mouldboard of each plough body can be made convex curve shape.
Each plough body is preferably with hinged securement plough bed thereon and makes the plough bed forward two stop blocks of given position to.
Reversing frame is preferably made the form of parallel-crank mechanism, and the connection of this mechanism saves and operating mechanism's motion links.
No matter which kind of plough body pattern the plough of above-mentioned recommendation adopts and have or not colter and skin coulter, all can reduce the length of plough-body spacing greatly, thereby improve the productivity ratio of the flexibility of farming unit down to plough.
Essence of the present invention is as follows.
Plough has the horizontal plane reversing frame that is fixed on the bearing support, and this reversing frame can move to the operating position by means of hydraulic jack or other known similar device adjustment, and in operating position and the vertical transverse Plane intersects of passing through the reversing frame axis.Move to situation about intersecting with vertical fore-and-aft plane with the reversing frame of known other ploughs and compare, the reversing frame of this plough moves and can make the rotation of all working mechanism change to rightabout.Therefore, no matter each plough body rear portion can not contact the front portion of the plough body arranged side by side that suffers how closely when adjusting to the operating position.Simultaneously, when adjusting to the operating position, colter and skin coulter can not contact plough body yet.
Therefore, recommend the plough-body spacing crust of plough not depend on plough body length and whether colter is housed and skin coulter (plough of existing band horizontal plane reversing frame does not have colter and skin coulter).The degree that plough-body spacing can reduce, be mainly to be the native sheet conditional decision between plough body, passed through by simple faming technology requirement, if the soil layer top that the faming technology process that each skin coulter is finished is downcut by its is stayed on the ground of skin coulter back and under the deadweight effect by throwing in spacious ditch, meanwhile the soil layer that is downcut by the back plough body overturns voluntarily, is deposited in the ditch dug with a plow.
The plough of recommending can adopt the plough body of any pattern, but the combined type plough body has and is suitable for the different soils condition and the technological parameter of requirement of turning over, on the preceding rotating part of this combined type plough body, be fixed with the ploughshare wall part of band ploughshare, and be fixed with on its rear portion that mutual mirror-symmetrical ground installs left and the mouldboard part of turning over to the right.Reversing frame when adopting this plough body when plough is in the operating position is more little with respect to the established angle α on vertical transverse plane, and the plough body rear portion is left perpendicular to the corner ψ of the vertical plane of reversing frame also more little.Installation when the plough body rear portion with respect to vertical fore-and-aft plane
During angle γ=α, the plough body rear portion promptly is fixed on the reversing frame rigidly.For example, when α=40 °, during γ=40 °, the plough body rear portion is fixed on the reversing frame rigidly, is γ between ploughshare and the landside in the case
0The angle, this γ
0The angle equals or approaches 40 °.
Close along with plough body, the established angle α on the relative vertical transverse of reversing frame plane reduces.Therefore, plough shortly more, combinations thereof formula plough body rear portion is also simple more in the installation adjustment of operating position.
Because plough body is close and the plough contraction in length, may require deflection combined type plough body front portion and the transmission mechanism that adopts complexity successively.Therefore, preferably adopt short type ploughshare, be beneficial to when plough is adjusted to the operating position, to realize (synchronously) deflection and its transmission mechanism of simplification in the plough body front portion.Adopt short type ploughshare can make plough body cut native sheet at horizontal plane and cut not in placely, so that the part of native sheet is downcut by ploughshare, another part breaks away from soil block owing to tearing.According to the difference of soil condition, the native sheet of permission does not switch to the degree varies of position; If the short type ploughshare side edge limit of adopting with plough direct of travel at an angle and be sharpening, do not switch to degree even eliminate native sheet fully and do not switch to phenomenon just can reduce native sheet.
Do not switch under the situation that does not influence plough body work at native sheet, the shape of combined type plough body ploughshare can keep.At this moment the side edge limit of ploughshare is consistent with direct of travel, thereby under ploughshare length reduces situation with the anterior symmetry of mouldboard the anterior overhang of mouldboard is reduced, thereby its surface is increased with respect to the gradient of the native sheet of upset, if the anterior side of mouldboard is rectilinear words.The anterior changes in pitch of mouldboard and can reduce the quality of turning over the deviation of optimum value, this is undesirable.Therefore: on the combined type plough body, adopt short type ploughshare to keep the shape of ploughshare simultaneously again, just must change the shape of the anterior side of mouldboard, these sides are made convex curve shape.Plough body separates native sheet along convex curve by soil block and also has other advantages promptly to improve the upset and the reduction plough body resistance of native sheet.
Adorn two stop blocks in the front portion of combinations thereof formula plough body and can be used to make the plough bed that is hingedly fixed on the plough body to forward given position to, thereby also can simplify plough bed transmission mechanism.
Because reversing frame is movable to and the vertical transverse Plane intersects of passing through its rotating shaft, reversing frame can be made the form of parallel-crank mechanism, between points the distance of this mechanism on the straight line that is not parallel to the plough longitudinal axis is along with the deflection of reversing frame changes, because these circular arcs along different radii move.This performance of parallel-crank mechanism can be used to adjust plough body and skin coulter to the operating position (if the rotation joint of they and this mechanism link), also can be used to adjust colter and takes turns to the operating position (if they are to be fixed on vertical joint of mechanism).
The gabarit length dimension of recommendation plough is compared with any known plough of same working width and can be reduced 1/2～3/5.
Studies show that recommending plough gabarit length dimension when working width is 3.5 meters is 4.5 meters, can be suspended on the tractor compactly in supporting.
These characteristics of the present invention and advantage, can be by hereinafter specifying with accompanying drawing of plow structure further being understood, wherein:

The plough of Figure 15-band parallelogram reversing frame is in the position of the soil layer of turning over to the left and right, top view.
Plough (Fig. 1 and 2) is made up of with the anchor clamps 2 that are connected tractor bearing support 1.Horizontal plane reversing frame 3 is housed on bearing support 1 and makes reversing frame 3 with respect to hydraulic jack 4 or any other similar device of the vertical transverse plane 5 of passing through its rotating shaft 6 to the same angle [alpha] of two edge run-outs, reversing frame 3 should guarantee that in the installation of bearing support 1 reversing frame 3 can intersect on this position reversing frame 3 and vertical transverse plane 5 through the mobile operating position of adjusting to for this reason.
Fix left and the plough body of turning over to the right on reversing frame 3, each plough body can guarantee soil layer alternately upset round about.
The combined type plough body is installed on the plough shown in Fig. 1 and 2, and each plough body is formed by front and back two parts.
Plough body front portion (Fig. 3,4,5,6) includes the plow standard 7 hinged with reversing frame 3, is fixing the mouldboard symmetric 8 with ploughshare 9 on plow standard 7, and its symmetrical plane 10 is by the vertical axis 11 and ploughshare 9 centers of plow standard 7 deflections.
The plough body rear portion includes plow standard 12, fixing thereon that mutual mirror-symmetrical installs left and the mouldboard part 13 and 14 of turning over to the right.Plow standard 12 is connected with reversing frame 3, and this connection should guarantee that the plough body rear portion is transferred to the operating position.If this position can only guarantee that then plow standard 12 is rigidly fixed to (Fig. 2,5,6) on the reversing frame 3 by reversing frame 3.If the operating position at plough body rear portion can not get guaranteeing during reversing frame 3 deflections, then the installation of plow standard 12 should be able to guarantee it by perpendicular to the vertical plane 15 of reversing frame 3 to two edge run-out α angles (Fig. 1,3,4), and ψ=α-γ, the necessary corner in operating position is adjusted at ψ in the formula-plough body rear portion; The angle that reversing frame 3 longitudinal axis 16 of α-be in operating position and vertical transverse plane are 5; γ-be in the plough body rear portion symmetrical plane 18 of operating position and the angle of 17 of vertical fore-and-aft planes.
Mouldboard symmetric 8 and when suitably dock form complete mouldboard with the mouldboard part 13 and 14 of turning over to the right left, this complete mouldboard can guarantee to turn over soil layer left and to the right when working.
In order to make the plough body front portion can forward the operating position to, plough must have certain transmission mechanism (not shown).The plough body rear portion is to the rotation of operating position, if this rotation is necessary, can utilize any known drive mechanisms or accomplished under the effect of the soil layer of being turned over.
Plough has bogie wheel 19(Fig. 1,2), in order to guarantee given ploughing depth.
Plough can have colter and skin coulter, the technical process that each skin coulter is finished is: cut soil layer top stay on the ground of skin coulter back and under the deadweight effect by throwing in spacious ditch, meanwhile overturn voluntarily, be deposited in the ditch dug with a plow from the soil layer that soil block downcuts by the back plough body.Use this skin coulter to need not to strengthen plough-body spacing, and need strengthen plough-body spacing during the spacious ditch of leaving by soil layer top to the front plough body that the throwing skin coulter of skin coulter own downcuts.
Because the plough body rear portion can be by vertical plane 15 to two edge run-outs, this combined type plough body can have optimal parameter, because these parameters are irrelevant with the α angle.Therefore, same plough (its reversing frame 3 is contained in the operating position and disposes plough body on reversing frame 3 by certain requirement) can use the plough body of different parameters, make plough can be under any soil condition works fine.
Shown in Fig. 3,4 and 6, if 9 pairs of vertical fore-and-aft plane 17(landsides of ploughshare) established angle γ
0Differ very little with the α angle, then the plough body rear portion both can be mounted to deflectable (Fig. 3 and Fig. 4), also can rigidly fix (Fig. 6).Under first kind of situation, α and γ are unequal mutually, and both equate under second kind of situation.As seen from Figure 6, under the situation about rigidly fixing at the plough body rear portion, mouldboard rear portion 13 and the mouldboard rear portion 14 of turning over to the right of turning over left is (the γ that install at an angle mutually
0Unequal mutually with the γ angle).
When plough-body spacing only depends on the condition that native sheet passes through between plough body (this situation betides plough and goes up native sheet top throwing that the skin coulter that uses can not downcut its when having adopted dehorner in ditch dug with a plow the time or on the plough), the spacing that plough body distributes on reversing frame 3 can be littler than the total length of ploughshare 9, and the ploughshare total length equals B/sin γ
0(B-plough body working width, γ
0The established angle of 9 pairs of landsides of-ploughshare).In this case, can not since ploughshare 9 by wedging and the combination of deflection simultaneously plough body front portion, therefore each plough body of deflection successively so just needs the transmission mechanism of complexity.If can make short type to ploughshare 9 and deflection when can realize the plough body front portion is just can simplify the structure of above-mentioned transmission mechanism greatly.
Reduce ploughshare 9 length to being not more than plough-body spacing, just must the change ploughshare 9 itself shape or the shape of change mouldboard front portion 8.
As seen from Figure 7, reduce ploughshare 9 length L and keep the shape of ploughshare side 20,21 and the shape of anterior 8 sides 22,23 of mouldboard simultaneously again, mouldboard front portion 8 is reduced together with the overhang L of ploughshare 9, but this situation be undesirable.In addition, ploughshare 9 length L reduce also to cause soil layer to cut A not in place and B.
In order to keep the overhang L of mouldboard front portion 8 together with ploughshare 9, simultaneously also be in order to reduce so that elimination soil layer under the short type ploughshare of employing 9 situations is cut phenomenon not in place, a kind of plough with the combined type plough body is arranged, and direct of travel 24 β and be sharpening (Fig. 8,9 and 10) is at an angle made and ploughed to the side 20 and 21 of its ploughshare 9.Ploughshare 9 shapes of being taked can reduce soil layer and not switch to position (Fig. 8) over half even eliminate fully and do not switch to a phenomenon (Fig. 9 and 10).
The plough of another kind of band combined type plough body soil layer occurs and does not switch to an A and B when not influencing plough body work when ploughshare 9 length L reduce, in order to keep the overhang of mouldboard front portion 8 together with ploughshare 9, mouldboard front portion 8 sides 23 and 22 are made (Figure 11) of convex curve shape.
Be that plough bed 25 is hingedly fixed on the plow standard 7 of plough body front portion at fixedly one of the pattern on the combined type plough body-plough bed shown in Figure 12 and 13.But fixed pan colter 26 on plough bed 25.Stop block 27 and 28 are arranged on the plow standard 7, and it act as by turn round plough bed 25 and when making the plough bed and during on the left side and the landside that reclines on the right of plough direct of travel 24.Shown in Figure 12 is the plough body front portion of position of turning on the right side, walk around at these position plow standard 7 clockwise directions, stop block 28 makes plough bed 25 clockwise directions turn round and it is transferred to plough direct of travel consistent, so just act on the plough bed, make the plough bed when plough body is worked, accept to act on the side force of plough body from the right from the right.Shown in Figure 13 is the plough body front portion of position of turning on a left side, counterclockwise change at this position plow standard 7, stop block 27 makes plough bed 25 counterclockwise turn round and it is transferred to plough direct of travel consistent, so just act on the plough bed, make the plough bed when plough body is worked, accept to act on the side force of plough body from the left side from the left side.
When plough bed 25 was not with colter 26 work, the plough bed acted on landside.In this case, the soil of different densities and viscosity certainly leads to certain reaction force, and soil (landside) distortion is also different.Plough bed 25 balanced actions in the cross component force of the soil resistance of plough body for fear of plough inclination (not taking the air line) and utilization, direct of travel 24 position at an angle must be adjusted to and ploughed to the plough bed, soil deformation is big more, and this angle also should be big more.This established angle of plough bed can be adjusted with pressing plate 29, and this pressing plate is fixed on the plough bed 25 with screw 30, and its front portion contacts (Figure 12,13 and 14) with 28 with stop block 27.On the pressing plate 29 elliptical aperture is arranged, in order on plough bed 25, can change the position of (adjustments) pressing plate 29 on plough 25 longitudinal axis, 31 direction fixedly the time.Since the pressing plate that contact with stop block 27 and 28 respectively 29 surfaces 32 and 33 be symmetry and and plough bed 25 longitudinal axis 31 between certain inclination angle is arranged, therefore the position with respect to plough bed 25 moving press plates 29 can change plough bed 25 with respect to established angles of ploughing direct of travel 24.
Shown in Figure 15 is a kind of structural shape of plough, its reversing frame 3 is made the form of parallel-crank mechanism, its part comprises front rail 34, the rear transverse rod 35 that is hinged and vertically saves 36, this parallel-crank mechanism by articulated joint 37,38 and hydraulic jack 4 or similarly any other device connect with bearing support 1 so that cross bar 34 and 35 can be with respect to moving same angle [alpha] by the vertical transverse plane 5 of cross bar 34 or 35 gyroaxises 39 or 45 to both sides.
Fixing plough body on rear transverse rod 35, the revolution plow standard 7 of each plough body front portion connects with front rail 34 by lever 41 and connecting rod 42 under the situation that adopts the combined type plough body, and ploughshare 9 length are no more than along the plough-body spacing of cross bar 35 axis 16.Vertically saving fixed bearing wheel 19 on 36, and colter and skin coulter (not shown among Figure 15).
The skin coulter of using on the plough has symmetrical working face, is similar to the surface of cultivator arrow shaped share or combined type plough body front portion.Be rigidly fixed on vertical joint 36 hinged securement and get in touch under second kind of situation with the joint motion of being connected of parallel-crank mechanism at skin coulter pillar under first kind of situation.
Plough body also can be fixed on the front rail 34, at this moment if use the combined type plough body, then must the anterior plow standard 7 of plough body be connected with rear transverse rod 35 by lever 41 and connecting rod 42.
Because one of reversing frame cross bar 34,35 links with anterior plow standard 7 motions of plough body that are fixed on another cross bar 35 or 34, therefore as previously mentioned, can utilize parallel-crank mechanism can change front rail 34 when its deflection and come deflection plow standard 7 with the characteristic of rear transverse rod 35 any distance between two points, these any 2 is not to be connected on the horizontal straight line with 40 being parallel to cross bar 34,35 rotating shafts 39.
Recommending the working method of plough is that example is summarized as follows with above-mentioned last kind structural shape:
When plough is advanced in the field, skin coulter downcuts soil layer top and soil layer top is stayed on thereafter the ground, and plough body separates soil layer from soil block and makes its upset, is deposited in the ditch dug with a plow that the plough body that moves ahead leaves, and down transfer to bottom of trench by soil layer top vegetation under action of gravity that skin coulter downcuts this moment.Can rotate job order by corresponding change plough body in order to change the direction of turning over, can the plough body on one side of need turning over be moved ahead by means of the hydraulic jack 4 clockwise or reversing frame of deflection counterclockwise 2 α angles for this reason.In reversing frame deflection 2 α angles, the operating position is transferred in the plough body front and rear part.The operating position is transferred in each plough body front portion must utilize cross bar 35, connecting rod 42 and lever 41, each plough body rear portion is transferred to the operating position and must be utilized cross bar 35 and make that it is not shown by vertical plane 15() rotate the mechanism at ψ angle, perhaps utilize the effect of cross bar 35 and the soil layer of turning over that its rotation ψ angle is contacted with cross bar 35 until plough body rear portion stop block 43 or 44.Along with reversing frame and plough body front portion forward operating position plough bed 25(Figure 12,13,14 to) and the skin coulter of hinged securement also be transferred to the operating position.Plough is that shuttle type ground moves along the field, and when its direction of motion changed to rightabout, parallel-crank mechanism and plough body promptly are transformed into the position of turning over, the right side by the position of turning over, a left side, and be perhaps opposite.
The present invention is applicable to the main ploughing and weeding operation in agriculture field, can replace general reversible plow and other cultivating ploughs, and it is suitable for both also turning over to the right to the left side in the plough shuttle type is advanced.The plough of recommending is owing to be underslung, and is also superior than half traied plough of turning on one side, so also can be used to replace this plough.
