Description

Novel ditching machine soil distributing apparatus

Technical field

The utility model relates to the governor motion of the earth separation plate setting angle of a kind of structure of ditching machine soil distributing apparatus, particularly soil distributing apparatus.Belong to agricultural machinery technological field.

Background technology

The cutterhead top of existing front-end ditching machine generally all is provided with a V-arrangement soil distributing apparatus (generally being made up of earth separation plate and skeleton etc.), 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 structure is generally by the earth separation plate of the clam of two block of material splicings, similar two expansion, fixes with two or four bracing frames (or skeleton) and ditching machine.From the cutterhead end on observation, the V-arrangement bottom earth separation plate lower limb line of soil distributing apparatus is the curved arch close with cutter radius, the V-arrangement angle at soil distributing apparatus front end and rear portion is basic identical, 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.Its shortcoming is: 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, so can not satisfy the demand of novel zero tillage and interplanting agronomy; 2, can not adapt to different soil properties.The soil distributing apparatus of prior art is installed on the elevation of cutterhead top and fixes, 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.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 uncontrollable fixed elevation of the soil distributing apparatus of prior art, height can not adapt to the requirement of different soil properties and agronomy.3, 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, soil distributing apparatus be installed on the variation of the elevation angle size of cutterhead top and height to the safety of trench digging machine operation, throw the native uniformity and prevent that particularly 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 variation that earth separation plate is installed on the elevation angle size of cutterhead top and height 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, cutterhead rotates counterclockwise in a direction indicated by the arrow, soil is milled into fragment, and impelling goes out ditch with blade under action of centrifugal force, 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.

The utility model content

The purpose of this utility model provides that a kind of safety in utilization is good, moisture resistance is wet, throw the native uniformity and the coverage rate distance satisfies agriculture requirement, is convenient to adjust, and helps adapting to the novel ditching machine soil distributing apparatus of piece ditching operation of respectively tilling the land simultaneously.

The purpose of this utility model is to realize by the improvement to existing ditching machine soil distributing apparatus, novel ditching machine soil distributing apparatus, on the frame of ditching machine, install to connect a V-arrangement earth separation plate, it is characterized in that being provided with between V-arrangement earth separation plate and the frame the online structure of hinge that can regulate V-arrangement earth separation plate setting angle and install and be connected.It is to establish a support column on the frame of ditching machine that the online structure of described hinge is installed connection, inserted block is made on the support column top, establish a holder at the earth separation plate rear portion, inserted block is inserted in the holder, run through holder and inserted block with a clamping screw level, holder is provided with an adjustment screw that is used to regulate the earth separation plate setting angle.It is to establish a support column on the frame of ditching machine that the online structure of described hinge is installed connection, inserted block is made on the support column top, establish a holder at the earth separation plate rear portion, inserted block is inserted in the holder, with a clamping screw and bearing pin respectively level run through holder and inserted block, holder is provided with the pin shaft hole that is used to regulate the earth separation plate setting angle of several and bearing pin coupling.It is to establish a holder on the frame of ditching machine that the online structure of described hinge is installed connection, the earth separation plate rear portion is provided with inserted block, inserted block is inserted in the holder, with a clamping screw and bearing pin respectively level run through holder and inserted block, holder is provided with the pin shaft hole that is used to regulate the earth separation plate setting angle of several and bearing pin coupling.

The utility model is simple and reasonable, manufactures easily, installs easy to adjustly, is convenient to manipulate raising operation quality and operating efficiency.Because the earth separation plate rear portion is that the online structure installation of hinge is connected with the ditching machine frame, raise earth separation plate by cutting with scissors online structure, it is low then earth separation plate can be adjusted to the rear portion, the state that front end is high, the soil that cutterhead mills out make progress impelling with can produce far and near different throwings soil distance after earth separation plate collides, satisfy just in time that the earthing band is wide, overburden layer is wanted uniform agriculture requirement; Because earth separation plate front end distance of round outside cutterhead is big, helps throwing soil and reduce soil adhesion simultaneously; Rear portion distance of round outside cutterhead is little, and it is near to throw soil, helps the protection to the operator; The angle of earth separation plate can be according to the soil property of different water cut rate and convenient adjusting of field piece of different planting requirements with height, can causing on the earth separation plate is jammed influence normal operation because of soil sticks in a large number moist Tanaka, and the uniformity and the distance of throwing soil have satisfied agriculture requirement, have reached good earthing lid seed effect.

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, so the rear lower of earth separation plate wants near apart from the cutterhead distance; and the front end of earth separation plate 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 technical solutions of the utility model, the earth separation plate rear portion is near cutterhead, front end is high to be lifted, earth separation plate 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 close cutterhead in earth separation plate rear portion, according to earth separation plate 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; 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 earth separation plate guarantees operator's safety and does not influence two major functions of throwing soil.2. because the distance of earth separation plate lower limb line and cutterhead center (cylindrical) each point is unequal, the rear portion is low, the soil that front end height, cutterhead mill out make progress impelling with can produce far and near different throwings soil distance after earth separation plate collides, satisfy just in time that the earthing band is wide, overburden layer is wanted uniform agriculture requirement.

In order to make soil distributing apparatus can adapt to the soil of different water cut rate, in the technical solution of the utility model, be provided with the adjusting device of the online structure of a hinge at the rear portion of earth separation plate, the front end height that makes earth separation plate is that the angle of earth separation plate 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 soil distributing apparatus 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.Because the position of the online structure of hinge is in the rear portion of earth separation plate, earth separation plate can only be that the elevation angle is adjusted in the axle center with the clamping screw, the earth separation plate 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, solved a difficult problem for many years.
