Description
Technical field
The present invention relates to Farm mulch cleaning, recovery and reuse field, say more specifically a kind of residual mulching film recovery method and reclaim unit.
Background technology
Before 30 years, agricultural mulching is promoted, and helps the Chinese agriculture increasing both production and income.At present, the usage amount of the technological development of China's mulch film and covering with plastic film ranks first in the world.Along with agricultural mulching constantly promotion and application for many years, the mulch film remained in farmland is more and more, goes up under field conditions (factors) a century and all can not get degraded, and severe contamination environment.Residual mulching film harm is mainly manifested in following several respects: one, spoiled soil structure, affect gas permeability and the water penetration of farmland quality and soil, and cause crop yield decline; Two, the harmful substance in residual mulching film, can't grow and dead the crops root system, or be that this toxicity causes that crop growth is slow or yellow is dead; Three, a large amount of residual mulching films are present in the ploughing and weeding layer, and residual mulching film is wound around and causes the machine work parts of farming equipment not rotate, and affects agricultural machinery working; Four, do not clear up or clear the residual mulching film of abandoning in the edge of a field, by strong wind, blown afloat everywhere and be scattered, have a strong impact on rural environment.
The waste mulching film pollution problem has been " persistent ailment " that a lot of countries in the world face.Control farmland " white pollution " has become countries in the world when last instant work.The recycling and administration work of waste and old agricultural mulching is also one of China's project of paying much attention to, giving special assistance to, and is the Important Action of relation descendants's survival and development in the future!
The method of administering at present the waste mulching film pollution mainly contains:
One, promote biological degradation recoverable environmental protection type mulch film, reduce agricultural mulching " white pollution ", but in prior art, no matter be the Biodegradable films such as liquid film, Light lysis Film or tunica fibrosa, in agricultural production test, more or less all have problems, particularly immature the and market price factor of technology causes Biodegradable mulch to be difficult to for many years popularization.The crop genetics in northern China and northwest China area still needs omnidistance overlay film, but the Biodegradable mulch film is two to three times of general agricultural mulching because it is on the high side, and the peasant can't bear at all.The immature of technology is also the significant obstacle of promoting, and degradative plastic film often loses soil moisture conservation, heat-insulating property in the agricultural growth later stage, and some films did not even also have the just weathering of crop growth phase.
Another serious problem is, crisp after the Biodegradable mulch degraded is easily glued together with soil particle owing to containing the organic matters such as starch, vegetable fiber, and recovery difficult is larger than common agricultural mulching, generally will not reclaim.But Biodegradable mulch is embedded in soil for a long time in a large number, can or can not affect soil reclamation actually, be degradablely for harmless carbohydrate, not pass through scientific appraisal, temporarily cannot determine.But a large amount of synthetic compounds enters in soil, can predict very likely bring disguise stronger, cause the soil can't the Planting Crops contaminant problems.This problem is along with scientific and technological detection level improves constantly, residual compounds after the Biodegradable mulch degraded necessarily is familiar with gradually and realizes by people the impact in soil, this will repeat the old road of " polluting-administer-pollute again-administer ", and how will we this generation people go to face our descendants in the future that today?
Even Biodegradable mulch can be degraded completely, but the application of this Novel mulching film can not reduce and remained in now the useless film in farmland, i.e. the application of Novel mulching film can't solve at present the mulch film problem to the soil reclamation severe contamination.
Two, adopt measure artificial and that the machinery recovery combines, spend a large amount of manpower and materials, reclaim the residual mulch film of soil surface by manpower craft or rake, the useless film machinery of existing recovery is mainly tractor-drawn multilayer comb type rake or annular rolling spiketooth type residual mulching film scavenger, also has the novel useless film machinery of part to reclaim and is embedded in the mulch film (0 ~ 8cm degree of depth) in earth.But aforesaid way all can only be picked up a large useless film of farmland surface, has no effect to removing the annual useless film remained between soil cultivating layer (10 ~ 30cm degree of depth) that constantly increases, because the mulch film of this degree of depth is owing to burying for many years, with soil, strike up partnership, by mechanical mode, reclaimed, the dynamics of having dug is too little can't pull out the mulch film of this degree of depth, and the dynamics of having dug is too greatly easily broken mulch film, can't pull out mulch film equally.And aforesaid way can only be larger for reclaiming area, longer mulch film, for the mulch film fragment, have no idea fully, the mulch film of small size basic just by the way an animal-drawn seed plough go out.For the mulch film reclaimed, a lot of modes of processing are to pile up to get up to be burned, and cause the secondary pollution to air.
According to the correlative study data, show, even adopt a large amount of manpower and materials to be reclaimed, cultivate in full 10 years agricultural land soils every mu and still contain 17 kilograms of residual mulching films, cultivate in full 20 years agricultural land soils every mu and still contain 28 kilograms of residual mulching films, cultivate in full 30 years agricultural land soils every mu and still contain 45 kilograms of residual mulching films.Along with the prolongation of land farming phase, in farmland, residual mulching film quantity will increase sharply, and after 50 years, this soil can't be cultivated, even now, the survival rate of crops also descends along with the increase of the content of mulch film in soil.Therefore, how to process the problem of the regional arable land residual mulching films such as current China northeast, northwest, the plantation ability of recovering soil is to concern the large problem of China's people's livelihood and following national strategy.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned defect of the prior art, provide a kind of not only can earth's surface and can bury the residual mulching film recovery method reclaimed in the residual mulching film of underground and reclaim unit.
The present invention is achieved through the following technical solutions above-mentioned purpose.
The present invention has designed a kind of residual mulching film recovery method, specifically comprises the following steps:
S1. the dirt bed scarifying that residual mulching film is contained in earth's surface;
S2. the earth of scarifying is scooped up in the lump together with residual mulching film;
S3. by beating, residual mulching film is come off from earth the earth and the residual mulching film that scoop up, and carry out centrifugation residual mulching film and earth;
S4. residual mulching film is collected.
Method of the prior art generally can only be reclaimed the residual mulching film be exposed on earth's surface, or reclaims a small amount of residual mulching film be imbedded on a small quantity the ground shallow-layer, for being imbedded in a large number under earth's surface, particularly the mulch film of deep layer can't be reclaimed.The present invention directly will bury the earth's surface dirt bed scarifying of mulch film, then the earth of institute's scarifying is all collected together with the residual mulching film of being routed up, the mixture of these earth and residual mulching film is carried out to centrifugation, finally the mulch film of separating is collected.Like this can be completely by bury with earth's surface under, residual mulching film of the remote past all reclaimed, and makes land restoration cultivate ability.
For can be efficiently, thoroughly earth is separated with residual mulching film, in described step S3 in centrifugal separation processes, earth and residual mulching film are placed in the double-layer cavity that internal layer shell is the hollow out housing and rotate, centrifugal force makes earth through the hollow out housing, and residual mulching film is stopped, is retained in the hollow out housing by the hollow out housing, realize two kinds of separation.The structure of the double-layer cavity that above-mentioned internal layer shell is the hollow out housing plays crucial effect, in reclaiming earth and the internal layer shell of residual mulching film mixture at this cavity in the process of high speed rotating, because mud particles is less, and the residual mulching film area is larger, so under the effect of centrifugal force, mud particles can be passed through the mesh on the hollow out housing, and residual mulching film can't pass, within just being retained in internal layer shell.Outer casing generally adopts the structure of sealing or semitight, can stop and be centrifuged the earth thrown away, and prevents that earth from flying upward under the high speed centrifugation effect everywhere.The general opening of Semi-seal structure is positioned at the bottom of housing, and the earth of separating can directly be got back on ground, fills up because the vacancy of front scarifying the earth that scooped up.
For operation that can be continuous, the dirt bed scarifying that continuously residual mulching film is contained in earth's surface in described step S1; In described step S2, continuously the earth of scarifying is scooped up in the lump together with residual mulching film; The earth of separating in described step S3 directly is expelled to earth's surface, and is calmed down.In this method, described outer casing adopts Semi-seal structure, and earth is directly discharged from the opening of outer casing downside, and then is calmed down, and makes land restoration smooth.In the process of this continuous productive process, earth and residual mulching film are dug and are shoveled out, through backfill and smooth again after separating, through post-job soil with originally as broad as long, but on earth's surface and the residual mulching film be imbedded under earth's surface be separated and reclaimed.
For earth thoroughly being separated with residual mulching film, reduce in the residual mulching film reclaimed and be mingled with a large amount of earth, prevent earth and the nutrient loss of ploughing.In described step S3, centrifugation comprises the following steps:
S31. pat earth and residual mulching film by impeller mechanism, drive earth and residual mulching film simultaneously and rotate and carry out centrifugal first separation; By impeller mechanism, the earth and the film mixture that scoop up are carried out to the high speed beating, in the process of patting, earth thoroughly can be separated with residual mulching film, particularly for residual mulching film of the remote past, that be imbedded in the earth deep layer, these mulch films are through burying for a long time, with earth, form a scab into piece, the mode of patting by high speed can be clapped these clods broken, and residual mulching film is separated.Under the effect of patting in the impeller mechanism high speed rotating in addition, can drive earth high speed rotating in above-mentioned double-layer cavity, separatory operating on centrifugal force is provided.
S32. the residual mulching film after separating by wind drive and be mixed in the centrifugal secondary separation of being spinned of earth in residual mulching film.Through the residual mulching film after centrifugal beating, the earth on it comes off basically, but still has a certain amount of earth to be clipped between residual mulching film, in the rotation process of impeller mechanism, can be taken out of in the lump, for these earth are also reclaimed.The present invention provides the mode of wind drive by the blast machine, drive residual mulching film and earth mixture and do spin motion in another double-layer cavity, by operating on centrifugal force and hollow out internal layer shell, earth is separated equally.After the processing of twice separation, can access clay content residual mulching film seldom, this residual mulching film collects and can directly be recycled, and processes without the mud that goes of doing again.
In order to adapt to, work continuously, in described step S31, the air-flow of the screw propulsion formed by impeller mechanism, drive earth and residual mulching film and advance, and carries out centrifugal first separation in traveling process; Air-flow by screw propulsion, can promote earth and residual mulching film from a lateral movement of cavity to opposite side, in this process, earth is thrown out of outside interior side body, residual mulching film is pushed into centrifugal secondary separation, so just can be constantly adds new earth and the mixture of residual mulching film is processed in cavity.Earth spiral inclination in driving residual mulching film and be mixed in residual mulching film by wind-force in step S31 is upwards advanced, and carries out centrifugal secondary separation in traveling process; In same process of advancing at spiral, earth is separated, the direction be tilted to can utilize earth and residual mulching film under the not same-action of Wind power propelling, utilizes the effect of gravity earth to be collected to the bottom of cavity, the earth be mixed in film can be separated more thoroughly.
In the soil that China's employing agricultural mulching is cultivated for many years, length according to the time of using, mulch film remains in the degree of depth difference under earth's surface, age is more remote, the degree of depth of burying is darker, according to the result of investigation, use the earliest the Northwest of agricultural mulching, contain the residual mulching film more than 98% in the degree of depth of earth's surface 30cm.In said method, scarifying and the earth scooped up are darker, and the load of the machine of operation is just larger, earth number formulary to be processed is just more, and the efficiency of processing is lower, is the energy consumption of balance machine, the efficiency of processing, in step S1 of the present invention, the degree of depth of scarifying earth is between 25 ~ 35cm.Process the earth of this degree of depth, the mulch film be imbedded under earth's surface not only can be removed comparatively thoroughly, and the energy consumption of equipment and efficiency all relatively are applicable to the soil of large tracts of land mechanized farming is processed.
In order to make earth and the residual mulching film can be looser before carrying out centrifugal treating, be conducive to pat and centrifugation, described step S2 comprises the following steps:
S21. the step earth of scarifying cut; The process cut not only can be provoked the residual mulching film that area is larger, and the clod of bulk can be divided into to the fritter clod, so more is conducive to follow-up beating and centrifugal treating.The much knives tool that the cylindrical shape main wheel that is 250 ~ 800 rev/mins by rotating speed in this step S21 drives is cut earth.The structure of cylindrical shape main wheel can prevent that residual mulching film is wound on main wheel, and the density of cutter arranged side by side can be set according to actual needs, and density is larger, cuts clod just less.And highdensity cutter just can be provoked most earth and residual mulching film in the process of high speed rotating.
The step that S22. will scoop up in the lump together with residual mulching film through scarifying or the earth cut.In carrying out the process that high speed rotating cuts, can provoke a large amount of earth and residual mulching film, remaining a small amount of earth and residual mulching film scoops up in the lump by shovel board, can reclaim thoroughly by all earth and residual mulching film more than the scarifying degree of depth.
Residual mulching film after wind drive is separated will be reclaimed, but blast now is larger, so step S4 specifically comprises:
S41. residual mulching film air-flow driven carries out the step of release of pressure; Specifically by the residual mulching film that air-flow is driven, import in a hollow out recovery cavity and carry out release of pressure.Through the residual mulching film after release of pressure, in reclaiming cavity, freely fall.
S42. collect the residual mulching film fallen and carry out the step of packing automatically.
The present invention also further provides the recovery unit that is applicable to above-mentioned residual mulching film recovery method, it is characterized in that being equipped with following system on the traction frame:
The dirt bed scarifying that residual mulching film is contained in earth's surface, and the earth of scarifying is delivered in the lump to the soil scarifying rotary tillage induction system of next system together with residual mulching film;
The centrifugal separation system that the earth that scoops up and residual mulching film are carried out to centrifugation; With the collected residual film of the residual mulching film by after separating, collect and the compression packaging system.
Said system order on the traction frame is installed, by tractor or other power towing towing bracket, just can drive a whole set of unit that reclaims advances, earth and residual mulching film are constantly dug, are scooped up, are separated, are discharged earth, backfill, smooth earth and finally residual mulching film collected to packing, pipelining, can carry out the mechanization processing to large-area arable land.
In order to carry out above-mentioned twice centrifugation, described centrifugal separation system comprises:
Pat earth and residual mulching film, drive earth and residual mulching film simultaneously and rotate the earth film piece-rate system of carrying out centrifugal first separation; With
Residual mulching film after drive separating and be mixed in the spinned selection by winnowing earth film piece-rate system of centrifugal secondary separation of earth in residual mulching film.
Above-mentioned each system concrete structure is as follows:
The first homework department that the soil scarifying rotary tillage induction system of machine for recycling mulch film group is the machine for recycling mulch film group, its structure comprises deep ploughing rake tool mechanism, rotary blade wheel mechanism and the actuating unit be arranged on the traction frame, deep ploughing rake tool mechanism is arranged on rotary blade wheel mechanism front, and described actuating unit drives the rotary blade wheel mechanism.During operation, by machines such as tractors, pull the traction frame, drive whole unit and advance, described deep ploughing rake lamps structure is positioned at frame foremost, and for the earth scarifying by the soil cultivating layer, the degree of depth of scarifying is according to actual needs generally between 10 ~ 40cm.Deep ploughing rake tool by the figure layer scarifying of this degree of depth to a certain extent, actuating unit drives rotary blade wheel mechanism High Rotation Speed, earth is beaten to pine again, when bulk earth is broken, will by earth be communicated with the mulch film remain in earth and a large amount of earth digs, send in the lump in the earth film piece-rate system of next stage and do further processing.This equipment is compared with traditional machine that mainly digs mulch film, be characterized in residual mulching film and earth are dug in the lump, can farthest the residual mulching film in earth be cleared fully, particularly be positioned at the earth deep layer, with the caked residual mulching film of earth, this mulch film adopt traditional equipment firmly too little being difficult to it is thrown, the excessive mulch film of easily breaking of exerting oneself, also can't dig.This equipment digs mulch film and earth in the lump when smashing clod, even break mulch film, also it doesn't matter, because the mulch film after breaking still can be communicated with earth, is dug in the lump.
Rotary blade wheel mechanism of the present invention comprises the cylindrical shape main wheel and is distributed in the much knives tool on the cylindrical shape main wheel.The cylindrical shape main wheel of this structure can prevent large or longer mulch film winding rotary blade wheel mechanism, and the much knives prodigiosin of intensive layout is enough quick and highdensity to be cut earth, shreds fast or tear large-area mulch film.Another effect that adopts the cutter of intensive layout is to play the native effect of plane, even the intensive cutter longitudinal arrangement under high speed rotating, also can force a large amount of earth to move towards a direction, so just play the double action that cuts earth and dug earth simultaneously.Described cutter can adopt dismountable mounting structure, so that the replacing after tool damage and maintenance.
In order to improve the efficiency that cuts earth and dug earth of cutter, reduce the power consumption of actuating unit.Cutter of the present invention comprises staggered rimmer knife tool and short sword tool, adopt the structure of staggered length cutter, can reduce the resistance that the rotary blade wheel mechanism advances, under the prerequisite of the power that does not improve actuating unit, improve the rotating speed of rotary blade wheel mechanism, the raising of rotating speed, just can further improve and cut earth and the native effect of plane.
Described rimmer knife tool and short sword tool preferably arrangement mode are that to be isosceles triangle staggered, and the protection rimmer knife tool that such arrangement architecture can be very high, prevent that the rimmer knife tool from use fractureing, and reduce the frequency of maintenance of equipment.In general, the length of described rimmer knife tool is between 25 ~ 35cm, and the length of described short sword tool is between 10 ~ 20cm, and the degree of depth in the scarifying soil of described deep ploughing rake tool mechanism is between 25 ~ 35cm.Result according to research, a large amount of residual mulching films mainly is deposited in the degree of depth of the following 30cm in earth's surface at present, the residual mulching film of this scope accounts for 98% of residual mulching film total amount, therefore for present case, the degree of depth in the scarifying soil of deep ploughing rake tool mechanism is comparatively reasonable between 25 ~ 35cm, and described length cutter is also designed according to this scope.
In order to improve the intensity of cutter, suggestion is dug native effect, and described cutter is curved, on the cylindrical shape main wheel, is radial distribution, and the rotating speed of cylindrical shape main wheel is 250 ~ 800 rev/mins.Can suitably adjust the rotating speed of cylindrical shape main wheel according to the hardness in soil, if but lower than 250 rev/mins, cut the native effect of earth and plane by not obvious, particularly dig native effect, in the situation that rotating ratio is lower, because cutter is radial distribution, a large amount of earth can't be dug, will not reach requirement.For current soil hardness, the rotating speed of 800 rev/mins has been enough to the earth of existing hardness is cut broken, and it is also little that rotating speed improves meaning again.The rotating speed of this equipment the best preferably is controlled between 300 ~ 500 rev/mins, and this rotating speed not only can be applicable to the at present use in most of arable land, and it is fairly obvious to dig native effect, and energy consumption is also moderate, is conducive to a large amount of applying.
For the stability of the running that improves equipment, deep ploughing rake tool mechanism comprises the subsides ground accessory whorl of both sides and is distributed in the rake tool pasted between the ground accessory whorl, and described subsides ground accessory whorl and cylindrical shape main wheel are on sustained height, and the degree of depth in described rake tool scarifying soil is between 25 ~ 35cm.Deep ploughing rake tool mechanism adopts the tilling depth identical with the rotary blade wheel mechanism, can fully the earth that will dig be carried out to pre-scarifying, and the further processing of rotary blade wheel mechanism is ready.The pretreatment of scarifying earth is more abundant, and its loss when carrying out operation of rotary blade wheel mechanism is just less, loads also less, and the effect that digs earth and residual mulching film is just higher.For this reason, for guaranteeing the reliability of deep ploughing, this patent increases and pastes the ground accessory whorl in the both sides of rake tool, and make subsides ground accessory whorl and cylindrical shape main wheel on same subsides ground level, the end of pasting ground accessory whorl and cylindrical shape main wheel is along in the same horizontal line, the degree of depth that can guarantee like this deep ploughing with cut earth, to dig the native degree of depth corresponding.
In order to guarantee the subsides ground property of deep ploughing rake tool mechanism and rotary blade wheel mechanism, this two mechanism all is connected with the traction frame by pasting the ground damping.Described subsides ground damping preferably adopts the hydraulic spring grease cup damper, is provided with this two equipment that pastes the ground damping and can maintains the performance that it pastes ground in being pulled the process of advancing, and is adjacent to different terrain and changes and carry out operation, effectively avoids Lou digging phenomenon.And the effect of damping can occasionally be avoided the rigid collision on equipment and ground, the safety of raising equipment.
In the situation that normal operation, described cutter and rake tool all go deep into below earth's surface, in the situation that non-operation will be moved this unit, just cutter and rake tool need to be increased to built on stilts.Therefore, the described traction frame of this patent comprises mainframe and lifting support, the mainframe below is provided with support wheel, and described lifting support is arranged on mainframe lifting relatively on mainframe, and described deep ploughing rake tool mechanism and rotary blade wheel mechanism are arranged on the reverse U shape lifting support.Mainframe is set directly on support wheel the stability that can guarantee traction, lifting support can drive deep ploughing rake tool mechanism and the lifting of rotary blade wheel mechanism, cutter is increased to higher than support wheel and contacts above water with ground with the rake tool, prevent that the traction in non-operation situation from damaging this cutter and rake tool.The degree of depth that another effect of lifting support can be adjusted this equipment deep ploughing earth and dig earth, for some residual mulching films in depth top layer be not too dark arable land, all reclaim separation without the earth by the following 30cm in earth's surface, the energy consumption in operation process just can reduce greatly like this.
In order to improve the effect that digs earth, reclaim by the earth of scarifying as far as possible and be mixed in the residual mulching film in earth, the described rotary blade wheel mechanism of this patent also is included in the cylindrical shape main wheel and the cutter top is the dashboard that semi-surrounding arranges.The effect of the dashboard of this semi-surrounding is to prevent that the earth dug by the rotary blade wheel mechanism of high speed rotating from splashing everywhere, it is limited in certain space, the corresponding earth film of the one side opening piece-rate system of described semi-surrounding, make earth can directed enter the processing that this system is carried out next step.
The present invention harrows tool mechanism by the earth scarifying of the certain depth below earth's surface by deep ploughing, further the rotary blade wheel mechanism by high speed rotating cuts into fragment by the soil layer of this scarifying together with the mulch film be mixed in soil layer, and most of earth and mulch film is dug and do further processing simultaneously.Paste the height that the ground shock mitigation system can make this two equipment adapt to earth's surface and change by arranging, and it is consistent to improve the degree of depth that structure makes deep ploughing rake tool mechanism process soil layer with the rotary blade wheel mechanism, reduced the load of rotary tillage cutter.The length arrangement that the rotary blade wheel mechanism is fixed a cutting tool reasonably is set, can further lowers energy consumption, improve the native effect of plane.Lifting support can make this equipment be applicable to be subject to the use in the arable land of different seriously polluted property, can further lower the energy consumption of equipment.
The earth film piece-rate system of machine for recycling mulch film group, comprise earth film separating mechanism, described earth film separating mechanism comprises housing with feed end and discharge end, be arranged on screen pack in housing, be arranged on the actuating unit that impeller mechanism in screen pack and impeller mechanism rotate, described screen pack distributes along the housing madial wall, with sidewall, keeps a distance.In operation process, the mixture of earth film enters in housing from feed end, in housing, by being patted at a high speed by impeller mechanism, earth is separated from residual mulching film, along with the high speed rotating of impeller mechanism, driving earth and residual mulching film advances to discharge end from feed end, in this process, earth can be by the mesh of screen pack, and residual mulching film can't pass, be retained in screen pack, thereby realized separating of earth and residual mulching film.Residual mulching film after separation still rests in screen pack, by impeller mechanism, is driven and moves to discharge end from feed end, finally from discharge end, discharges.
In order as soon as possible separating degree earth to be got rid of, be that the earth divided thin film is disembarked and can be worked continuously, the mixture of the earth film that constantly processing is newly carried out, described housing bottom is provided with the earth outlet.The earth filtered away from the screen pack mesh like this, receive that stopping still of housing be retained in housing, and naturally fall under the effect of gravity, from the earth outlet, discharges, and so just can guarantee the earth divided thin film continuous action of disembarking.
For the mode that can pat by high speed is separated earth as much as possible with residual mulching film, and the drive residual mulching film moves to discharge end from feed end, described impeller mechanism comprises impeller shaft and the many groups blade distributed along impeller shaft, described blade is radially vertical distribution on impeller shaft, and has the inclination angle that makes air mobile to discharge end from feed end.The earth film mixture, after charging aperture enters, is patted at a high speed step by step by many groups blade like this, in the process of patting, earth separates with residual mulching film, under the effect of centrifugal force, earth is thrown out of outside screen pack, and residual mulching film is retained in the screen pack the inside.Blade has certain inclination angle, can drive Air Flow, the mobile drive residual mulching film of air moves to discharge end from feed end, in the process moved at this, many group blades are realized the beating step by step to the earth film mixture, and earth is further separated with residual mulching film.
For residual mulching film can be separated fully with earth, removal sticks the impurity such as earth on residual mulching film, and earth or sandstone etc. is patted into to fragment simultaneously, enable the mesh by screen pack, the rotating speed of described impeller mechanism is between 1200 ~ 2000 rev/mins, and described inclination angle is between 5 ~ 50 °.Under the beating of metal blade so at a high speed, the earth that becomes piece can be patted to obtain and pulverize, because residual mulching film has certain toughness, under patting at a high speed, can not break.Blade is arranged to have certain inclination angle, best inclination angle is 35 ~ 45 °, can make the earth film mixture progressively advance, in the process that this mixture advances, beating step by step by many groups blade, can both further remove the earth sticked on residual mulching film for every grade, and leach from screen pack, last only remaining residual mulching film and a small amount of earth.The very light in weight of residual mulching film, the high speed winds of bringing in blade rotation is depressed, and can from discharging opening, get rid of fast.
In order to form the effect of patting step by step, described impeller mechanism comprises 2 ~ 8 groups of blades, and every group of blade is equally spaced along impeller shaft, and blade has identical inclination angle.The blade at the identical inclination angle of many groups is equally spaced, and can form stable air-flow, and what the residual mulching film after guaranteeing to separate can be stable advances towards certain orientation, prevents flow-disturbing, can not cause residual mulching film to be wound on impeller shaft.
In order to make earth as much as possible and to discharge as soon as possible, do not make residual mulching film block the mesh of screen pack, described housing is that integral body is cylindrical shape, and the earth outlet is arranged on the housing below along the housing axial distribution, screen pack is cylindrical shape steel wire screen cloth, and the distance of housing is between 3 ~ 30cm.Adopting the effect of steel wire screen cloth is exactly can make not clapped broken finger stone can pass through, and can not remain in screen pack, and residual mulching film drives quick rotation by impeller mechanism in this screen pack, can not block because inner and outer air pressure is poor mesh.The distance of screen pack and housing keeps certain distance, best between 10 ~ 20cm, remains with sufficient space and holds earth and the sandstone being clapped and pass through.Particularly near the front end of feed end, clapped the earth that falls and sandstone a lot of the time, if this distance is too little, earth and sandstone can't be discharged fast, can cause obstruction.Therefore larger distance is conducive to the separation of earth film mixture, but the volume in the too large screen pack of distance will be restricted, reduce the ability of processing mixture, therefore this distance still will keep moderate, through a large amount of experiment, the inventor thinks that this distance remains in above-mentioned scope and can guarantee carrying out smoothly of operation.
For the earth film mixture is sent into to feed end fast, without manual intervention, this system also comprises earth film induction system, comprise transport tape and the shovel board that is arranged on the transport tape front end, dock with described feed end described transport tape rear end, and the earth film mixture is sent into to earth film separating mechanism.Although can being mingled with major part the earth of residual mulching film, the soil scarifying rotary tillage induction system by before delivers on transport tape, but still there is part residual, by shovel board is set, the deep ploughing degree of depth that makes shovel board be adjacent to soil scarifying rotary tillage induction system is advanced forward, residual like this earth and residual mulching film will be scooped up by shovel board, and progressively accumulation, until finally fall on conveyer belt the shovel board rear end.The earth film mixture is by the transmission of conveyer belt, and the feed end that can automatically fall into earth film separating mechanism is separated, and this process, without manual intervention, realizes the job stream aquation.
For can be smoothly and scoop up fully the earth film mixture, this patent arranges described shovel board and shovels the native degree of depth between 25 ~ 35cm, and shovel board is inclined to set, and angle of inclination is between 20 ~ 40 °.Shoveling the native degree of depth is to be complementary with the soil scarifying rotary tillage induction system of front, and purpose is by the earth of scarifying, to be scooped up fully, makes residual mulching film reclaim more thorough.Inclination angle is preferably between 25 ~ 35 °, and inclination angle is too little, earth fully can't be scooped up, and inclination angle is too large, and the resistance of advancing has just strengthened, and has increased the burden of traction power, so within should being chosen in above-mentioned suitable scope.
For according to the actual job situation, the described earth film of this patent induction system also comprises that shovel board shovels the native degree of depth and angle regulator.Adjustment shovel board that can be real-time by the degree of depth and angle regulator is shoveled the native degree of depth and angle, with the height that is applicable to ground, changes and the variation of the degree of depth of deep ploughing, improves the adaptive capacity of equipment.
For the handling capacity of raising equipment to the earth film mixture, improve separative efficiency, this patent can be set up in parallel multi-section earth film separating mechanism on frame, the next 2 ~ 4 ones of ordinary circumstance.These earth film separating mechanisms can share an earth film induction system or be provided with independently earth film induction system, in the situation that the earth cubic number of processing is larger, the earth film mixture is assigned to multi-section earth film separating mechanism and carries out detached job, can reduce the load of each earth film separating mechanism, improve the efficiency of processing.
The present invention pats at a high speed the earth film mixture by impeller mechanism, both is separated, and by screen pack, both are separated.The earth film mixture is entered in housing and can advance in a certain direction afterwards, pat by multistage high speed in traveling process, earth is separated more thorough with residual mulching film.Earth after separation exports by earth the farmland that automatically falls go back to, prevents soil erosion, and the residual mulching film after separation is transported to the recovery of packing of next Working mechanism.Coordinate conveyer belt by shovel board, the earth film mixture that major part can be deep ploughed scoops up, and is delivered to earth film separating mechanism and is separated.Can reduce the resistance of traction by the angle that shovel board rationally is set, arrange multi-section earth film separating mechanism can reduce the load raise the efficiency, use the minimum energy to be separated the earth film mixture.
The selection by winnowing earth film piece-rate system of machine for recycling mulch film group, its structure comprises shell, setting screen cloth and the blast machine in the enclosure with charging aperture and discharging opening, and described screen cloth distributes along the shell madial wall, with sidewall, keeps a distance, and charging aperture connects the blast machine.After earth film piece-rate system is separated, residual mulching film is separated basically, because adopting the wind-force of impeller mechanism to drive film, earth film piece-rate system advances, so also be mingled with part earth or sandstone in the residual mulching film after separating, the purpose of the present invention's design is exactly in order thoroughly this earth or sandstone to be separated from residual mulching film.The residual mulching film that is mingled with earth or sandstone forms gas, residual mulching film and the silt mixed airflow of high pressure by the blast machine, from the charging aperture of selection by winnowing earth film piece-rate system, pump into, and enters in screen cloth.This mixed airflow constantly flows in screen cloth, and earth or sandstone can pass through the mesh of screen cloth, and film can't pass, and is retained in screen cloth, thereby has realized separating of earth or sandstone and residual mulching film, and finally remaining film is discharged from discharging opening.
In order to improve the effect of separation, described shell is obliquely installed, and described charging aperture is arranged on the shell lower end, and described discharging opening is arranged on the shell upper end.By the setting of tilting, mixed airflow is upwards flowed from having a down dip, earth or sandstone can naturally fall under the effect of gravity, and residual mulching film is lighter, will be taken to discharging opening by air-flow and discharge, by the difference of both weight, rationally utilize the effect of gravity to realize separating, save the energy.
Described shell angle of inclination should be reasonable, and general control is between 20 ~ 70 °, and angle is too little, and gravitational effects is not obvious, and angle is too large, and residual mulching film is not easy to discharge, preferably between 40 ~ 60 °.Separately because earth or sandstone fall under Action of Gravity Field naturally by after screen cloth, so bottom, shell lower end arranges the earth outlet, and sandstone or earth discharge at operation process, separating treatment being come, guarantee to work continuously.
In order further to improve separating effect, this patent is provided with the pivot post at described screen cloth center.Mixed airflow can form centrifugal action around pivot post rotation in mobile in screen cloth like this, makes separating effect more obvious.
In order to improve the spin effect of mixed airflow, described pivot post is provided with and promotes rotation flange or the groove that air moves towards discharging opening one end along charging aperture one end.Like this when mixed airflow in screen cloth when the pivot post is mobile, can form stable swirling eddy under the guiding of rotation flange or groove, prevent flow-disturbing and reduce from swirl effect.
In order improving from swirl effect, and to be conducive to film and finally to discharge, described shell is conical structure, and sectional area dwindles towards discharging opening one end gradually from charging aperture one end.The charging aperture of blast machine connected with outer casing front end, and shell is inclined to set, the wind motive force is just less more backward, therefore adopts conical shell can guarantee also have larger wind motive force at outer casing back, and be conducive to the residual mulching film that weight is lighter and collect, discharge from discharging opening.
In order to make earth as much as possible and to discharge as soon as possible, do not allow residual mulching film block the mesh of screen cloth, described screen cloth is conical steel wire screen cloth, along outer casing inner wall, distributes.Adopting the effect of steel wire screen cloth is exactly can make not clapped broken finger stone can pass through, and can not remain in screen cloth, and residual mulching film drives quick rotation by high pressure draught in this screen cloth, can not block because inner and outer air pressure is poor mesh.
The distance of described screen cloth and shell is between 3 ~ 30cm, best between 15 ~ 25cm.Remain with that sufficient space holds separated earth and sandstone passes through.Particularly near the front end of shell, clapped the earth that falls and sandstone a lot of the time, if this distance is too little, earth and sandstone can't be discharged fast, can cause obstruction.Therefore larger distance is conducive to the separation of earth film mixture, but the volume in the too large screen cloth of distance will be restricted, reduce the ability of processing mixture, therefore this distance still will keep moderate, through a large amount of experiment, the inventor thinks that this distance remains in above-mentioned scope and can guarantee carrying out smoothly of operation.
The larger finger stone of Particulate Inclusion likely in mixed airflow, these finger stones can't be by the mesh of screen cloth, but still is retained in the inside of screen cloth under the effect of gravity, can from discharging opening, not discharge with residual mulching film.But operation one end is after the time, and the amount of handstone runs up to certain degree and just need to clear out, and for this reason, this patent is provided with service port in described screen bottom, and service port is provided with closing door.Close during the closing door operation of service port, guarantee carrying out smoothly of operation, but when needing to safeguard, open this closing door, just can remove the handstone that is squeezed in filter screen bottom.
In order to improve the effect of separation, this patent charging aperture connects the blast machine by an inflection shape airduct.Airduct by inflection shape can make the residual mulching film that is mingled with earth or sandstone realize premixed with air in airduct, because air is different from the effect to residual mulching film to the effect of earth or sandstone, under the effect of pressure-air, earth or sandstone can come off or separate from film, in mobile process, with air, mix more evenly, premixed has further improved follow-up separating effect.
The present invention makes the residual mulching film and the air that are clipped in earth or sandstone form mixed airflow by the blast machine, mixed airflow is flow at high speed in the filter screen of shell, earth or sandstone can be thrown away to filter screen, and retain residual mulching film in filter screen, realize separating of residual mulching film and earth.By the pivot post is set, adopt coniform shell also to be obliquely installed, can further improve the effect of separation, and discharge from discharging opening after being conducive to residual mulching film and collecting.Rationally utilize the effect of gravity, can make earth or sandstone separate fast with residual mulching film, and earth or sandstone are discharged.After this system, the earth or the sandstone that in residual mulching film, are clipped in are cleaned basically, and residual mulching film can directly enter the packing operation of next stage.
The residual film of machine for recycling mulch film group is collected and the compression packaging system, its structure comprises collector and baling press, the at least part of sidewall of described collector sidewall is inclined to set, offer a plurality of releases of pressure hole on sidewall, residual film entrance is arranged on sidewall, residual film outlet is formed on the sidewall bottom, and baling press is connected in residual film outlet.Remaining residual mulching film only basically after selection by winnowing earth film piece-rate system, under the formed wind-force of selection by winnowing earth film piece-rate system ground promotes, residual mulching film enters collector from residual film entrance.The release of pressure hole that unnecessary wind-force sees through collector discharges, and residual mulching film is blocked in collector, under Action of Gravity Field, naturally falls.The setting of sloped sidewall can be collected to the residual mulching film fallen residual film exit, by Horizontal hydraulic package machine, will after the residual mulching film compression, be packaged into whole bundle.
In order to improve the efficiency of collection, the described collector of this patent is funnel-shaped structure, and a plurality of releases of pressure hole that sidewall is offered forms ventilative network structure.Cancellated collector can discharge wind-force fast, and funnel shaped structure makes that residual mulching film can be quick and concentrated is pooled to residual film exit, has so greatly improved disposal ability and the efficiency of equipment.
Because residual mulching film is very light, for the wind-force that prevents from newly advancing produces of short duration flow-disturbing in collector, the residual mulching film fallen is blown afloat again, reduce the efficiency of collecting, the described collector end face of this patent is network structure, and described residual film entrance is tilted to.Whole like this collector is network structure, and the wind-force direction is directly over against network structure, and wind-force is able to quick release after entering collector.The wind-force direction is tilted in addition, and entering Shi Buhui affects the residual mulching film that other have fallen after release of pressure.
Due to the rectangle structure of residual film outlet for distributing along the collector bottom, the hydraulic stem of baling press constantly moves back and forth below this residual film outlet, by residual mulching film compression, for the residual mulching film that prevents from falling enters the rear end of push rod, sideboard is located in the residual film exit of described collector.This sideboard is connected on the hydraulic stem of baling press, by the driving back and forth of hydraulic stem, controls its sealing or opens residual film outlet.Push ahead compression when residual mulching film when hydraulic stem like this, other residual mulching films that fall are stopped by baffle plate, just can not fall into the rear end of hydraulic stem, and what make that hydraulic stem can fast free is reciprocating, raises the efficiency.
For the earth of discharging after front plane system can being processed calms down, entirely the film-recovering machine group is passed through Land leveling afterwards, so that plantation, native system is as last procedure of whole unit, also comprise level land mechanism, described level land mechanism is arranged on the below of baling press.The earth of discharging before can be struck off by level land mechanism, make ground recover smooth.
