Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of soil distributing apparatus of ditching machine.
Background technology
The cutterhead top of existing front-end ditching machine generally all is provided with soil distributing apparatus, comprise earth separation plate and support column, concrete structure is a V-arrangement earth separation plate, fix (if frame is provided with directly the fixedly structure of earth separation plate with two or four support columns and ditching machine frame, can think that also this structure is the special case of " support column ", and said earth separation plate also is the soil distributing apparatus of indication in the utility model in this special case), its major function is: form refraction after impelling collides with it and divide the both sides of spreading ditch when soil that cutterhead mills out makes progress, prevent that simultaneously soil block from retrojecting to the operator, to guarantee safety.Its earth separation plate structure generally is with clam two block of material splicings, similar two expansion, fixes with two or four support columns and ditching machine.From the cutterhead end on observation, the V-arrangement of soil distributing apparatus bottom earth separation plate lower limb line is the curved arch close with cutter radius, and the V-arrangement angle at soil distributing apparatus front end and rear portion is basic identical.Adopt this structural reason to be: there is a kind of traditional prejudice in the design aspect at the ditching machine soil distributing apparatus.Because the size of cutterhead and soil distributing apparatus distance, the soil block that the meeting influence is dished out is by minute distance of throwing, so traditional concept is thought: the lower limb line of earth separation plate must present the concentric or approximate concentric arc with the cutterhead outer ring in the soil distributing apparatus, otherwise just can't realize evenly dividing the purpose of soil.Therefore the earth separation plate lower limb line of all soil distributing apparatus all is designed to arc; Owing to the design of this lower limb bank shape, the general two boards material that adopts connects when causing its manufacturing again, and the whole sheet material of difficult employing.The structure that this two boards material connects, or the structure that the lower limb line presents arc causes following shortcoming respectively: 1, throw the native uniformity and coverage rate distance and can not satisfy agriculture requirement.Ditching machine has not been used for merely digging trenches to drain the water away at present, a kind of novel zero tillage of agricultural sector's large-scale popularization in recent years and interplanting agronomy, be with seed broadcasting on the face of land of not ploughing, requiring ditching machine that the soil in the ditch is thrown to both sides evenly covers on the seed, and need a suitable distance: it is near excessively to throw soil, can make local soil layer thick partially, even make limes marginis form the accumulation ridge; It is far away excessively to throw soil, and the soil block of dishing out is splashed in the contiguous ditch.Because the lower limb line of curved arch earth separation plate and the distance of each point and cutterhead cylindrical are basic impartial, the soil that cutterhead mills out makes progress after impelling and soil distributing apparatus collide, the distance of throwing to both sides also is a basic impartial long narrow band, can not form the coverage rate of a broad in the ditching machine both sides, so can not satisfy the demand of novel zero tillage and interplanting agronomy; 2, intensity difference.Earth separation plate adopts two block of material to make, and the center-line joint place generally connects with electric welding or rivet, and the middle part is subjected to soil block impulsive force maximum, the damage of breaking easily; 3, easy clay.Because earth separation plate center-line joint position has adopted electric welding or rivet to connect, the surface is crude, learn according to general knowledge and test of many times, the earth separation plate surface is more smooth, the probability of soil adhesion is littler, otherwise it is then bigger, when in the strong soil of moist field adhesiveness, ditching, if the earth separation plate surface is very crude, just stick on the earth separation plate easily with its soil block that collides at a high speed, under " snowball " effect, sticking more many more, form the case shape when serious above cutterhead, soil block can not be dished out, and causes the ditching machine can't operation at last; 4, can not adapt to different soil properties.The soil distributing apparatus front end of prior art and the V-arrangement angle at rear portion are impartial; And the elevation that soil distributing apparatus is installed on the cutterhead top is (said here elevation is from the cutterhead end on observation, the lower limb line of earth separation plate and horizontal angle) of fixing, and can easily not regulate significantly, can not satisfy actual needs; Because different soil, the soil block that mills out then can produce different throwing soil movement locus; And soil property and soil moisture content is different, and stiff or sandy soil impelling native impelling far away, moist, tough is near.The elevation of soil distributing apparatus is little, and soil block thrown height and distance are just little, and protective is good, but soil is easy and earth separation plate adheres to; Otherwise the elevation of soil distributing apparatus is big, and soil block thrown height and distance are just big.Secondly, soil distributing apparatus is nearer apart from cutterhead, and the height and distance of soil block impelling is littler; Otherwise the height and distance of soil block impelling is just bigger.On the other hand, the V-arrangement angle of soil distributing apparatus also has confidential relation with the native situation of throwing: the V-arrangement angle is big, throws native distance and highly just little, and the soil block of high-speed projectile is also just little to the scouring force on earth separation plate surface; Otherwise the V-arrangement angle is little, and it is just big to throw native distance and height, and the last piece of high-speed projectile is also just big to the scouring force on earth separation plate surface, and the soil that sticks to the earth separation plate surface also just is not easy to form bigger walk.The farmland soil property is very complicated, even also can moisture content differs greatly owing to the height difference between the field piece that adjoins, so the identical V-arrangement angle in the uncontrollable fixed elevation of the soil distributing apparatus of prior art, height and front and back can not adapt to the requirement of different soil properties and agronomy.5, safety is good inadequately.If for prevent clay too much, can and increase that to throw soil zone wide in the smooth operation in moist field, when manufacturing with the elevation angle of soil distributing apparatus and highly the increase, but, when the operation of stiff field, will produce the problem that soil is crossed far influences operator's safety of throwing owing to there not being adjusting device easily.
This shows, the planform of soil distributing apparatus, angle and surface state prevent particularly that to safety, the native uniformity of throwing of trench digging machine operation soil adhesion from having extremely important influence, the earth separation plate of original fixed angle curved arch can not adapt to the characteristics that cutterhead is thrown native track and front and back soil block mass flow discrepancy weighing apparatus, the also requirement of protean different soil properties of incompatibility and agronomy.
Ditching machine is a kind of new type in agricultural machinery, its rotating speed height, contents such as the dynamic balancing that relates to, load, general structure layout are complicated again, people also are nowhere near to its research, in the process of research, often pay close attention to more to critical pieces such as the cutterhead of ditching machine, gearbox, frames, think that parts such as soil distributing apparatus are less important, its research and test also are nowhere near; And find the planform angle of soil distributing apparatus and distance, the uniformity of throwing native distance and prevent that moist soil block from adhering to earth separation plate and being jammed and throwing native passage very large relation is arranged according to our deep in recent years research and test repeatedly, practice.In the ditching machine operation, the cutterhead bottom forward, the top high speed rotating of (pressing direction shown in the arrow among the figure) backward, soil is milled into fragment by blade, under blade frictional force and effect of inertia with blade movement, outwards impelling under centrifugal action simultaneously, wherein most soil blocks in cutterhead central vertical line the place ahead forward and upwards, cutterhead central vertical line rear has only a spot of soil block backward, although ratio is little, consider from security standpoint, even if throwing to the operator, a soil also disapproves.This shows that the function of soil distributing apparatus must satisfy many-sided requirement: the first, throw the native uniformity and coverage rate distance and will satisfy agriculture requirement; The second, when the big moist Tanaka's operation of adhesiveness, can not produce obstruction because of soil adhesion; Three, to adapt to different soil properties; Four, prevent the soil that retrojects, to guarantee operator's safety.

Embodiment
Big according to the anterior soil amount of throwing of cutterhead, the soil block flow path direction is to make progress forward, and rear portion throwing soil amount is little, the soil block flow path direction is characteristics backward, in order to protect the operator, prevent the soil that retrojects, therefore the rear lower of hinge connection artis and soil distributing apparatus wants near apart from the cutterhead distance, it is big that the V-arrangement angle at soil distributing apparatus rear portion is wanted, and preferred plan is about 100 degree; And the front end V-arrangement angle of soil distributing apparatus is little, and preferred plan is about 60 degree, guarantee that soil does not adhere to and do not influence to throw soil, and the front end of soil distributing apparatus is that elevation angle adjustable range is about 45 degree, to adapt to the requirement of various soil and agronomy apart from the distance of cutterhead.
Adopt among the embodiment 1 of technical solutions of the utility model, the lower limb of earth separation plate is straight line or near linear shape, the rear portion is near cutterhead, front end is high to be lifted, soil distributing apparatus is skewed setting, through a large amount of facts have proved repeatedly, this technical scheme that seems " simply " that breaks through traditional conventional thought has changed people's set thinking for a long time, obtained following beyond thought effect: 1. because the earth separation plate lower limb is straight line or near linear shape, the rear portion is near cutterhead, apart from the nearer retaining mud of the cutterhead tight characteristics that heal, the rear portion can stop soil block, and impelling is far away excessively backward, has also just reached the good purpose of protection operator's safety according to soil distributing apparatus; And the front end soil distributing apparatus is bigger apart from the space of cutterhead, so can not stop the soil block of the impelling that makes progress forward, earth separation plate clay probability is little, helps in the operation of moist field; Having satisfied soil distributing apparatus guarantees operator's safety and does not influence two major functions of throwing soil.2. owing to adopt the simplest linear, also just can be converted into V-arrangement, make production technology simple, and saved material, reduce cost with a block of material.Again because earth separation plate lower limb line has adopted linear, unequal with the distance of cutterhead center (cylindrical) each point: the rear portion is low, the front end height, the soil that cutterhead mills out make progress impelling with can produce far and near different throwings soil distance after soil distributing apparatus collides, satisfy just in time that the earthing band is wide, overburden layer is wanted uniform agriculture requirement; 3. owing to adopt a block of material to make, middle no seam has improved intensity greatly; 4, simultaneously also owing to adopt a block of material to make, the centre does not have solder joint or rivet, and smooth surface is smooth-going, has also significantly reduced the adhesiveness of soil to it.
In order to make this rectilinear soil distributing apparatus better effects if, the soil that can adapt to the different water cut rate, the utility model has adopted an important measures again, adjustable hinge tight mechanism that interlocks promptly is set at the rear portion of soil distributing apparatus, the front end height that makes soil distributing apparatus is that the angle of soil distributing apparatus can be regulated, when when the strong moist Tanaka of adhesiveness ditches, lift the soil distributing apparatus front end is high, when the earth that sticks to the earth separation plate front end agglomerate that congeals into reaches certain volume, weight is during greater than adhesion, the walk piece will fall to cutterhead, pulverized by the blade of high speed rotating and dish out once more, and can not form the case shape stop up throw that native passage causes can't operation; In Fig. 1,2,3 described embodiment 1, the artis position of tight mechanism is in the rear portion of soil distributing apparatus because the hinge of support column and earth separation plate is interlocked, earth separation plate can only be that the elevation angle is adjusted in the axle center with the clamping screw, the soil distributing apparatus rear portion can not change significant change because of the elevation angle substantially apart from the cutterhead position, can guarantee the smooth operation in moist field like this, simultaneously can prevent that again soil block from retrojecting to the operator, moist field can in time be dug trenches to drain the water away, solve a difficult problem for many years.
The tight mechanism of hinge interlocking is easy to operate, and the angle that can conveniently regulate soil distributing apparatus is to reach requirement and purposes different under the different condition.For example when very stiff soil trench digging, force down the soil distributing apparatus front end, unlikely excessively far the splashing in the contiguous ditch of having held successfully of the soil block of throwing to both sides resulted in blockage; Safety might as well; And when in than wetland, ditching, then raise the soil distributing apparatus front end, to guarantee that earth is unlikely to stick on the earth separation plate and influence is thrown soil even influenced ditching operation.
