Abstract

Disclosed is an automatic cattle-plowing lever upturning seeder. An original form of cattle-pulling plowing is kept unchanged, a plow bend and a plow arm are changed to be of a leverage structure, half of pull tension of cattle is relieved, and a flat bracket is designed on the upside of a rung. A runner on the flat bracket is utilized to contact with soil and rotate so as to drive to complete seeding and fertilization, and automation is formed. The seeder has a heavy seeding type (for wheat) and a sparse seeding type (for corn, peanuts and soybeans), and a plow is taken as traction and the plow bend is taken as control for simultaneously and automatically completing plowing. Speed is high, and cattle-pulling mechanization is realized. The plow has a plowing upturning function, the plow arm is broken in half, three vertical pieces on a newly-welded small tube of an upper fracture and five cracks created by a lower fracture can control the plow to turn and position so as to complete plowing upturning, and the broken plow arms can be connected by hooking of a pole hook and grooves. The seeder has the plowing upturning function besides seeding, fertilization and plowing automation.

Description

Cattle is ploughed and turns over automatic seeder on lever

Technical field: belong to agro-farming field of mechanical technique.

Background technology: it is originally cattle hauling plough arable land technology that cattle ploughs lever automatic seeder, curved for plough and plough arm are changed over by the inside Lever mechanics framework, times amount alleviates the pulling force of cattle.Devising seeder on crosspiece, there is rake plough side, plough, sow, rake the soil level in Integrally, utilize Niu Li automatization, as sowing automatization ploughed by tractor.It also has another effect to be that plough arm front portion can be left Right turn, up can turn over slope soil.

Summary of the invention: the many mountain areas of China, hilliness area, hillside tiltedly also feature is many, and their state is, for a long time with Coming, hillside, slope land can only down be turned over by plough, and soil toward moving down, causes following blocked up be wasted, above soil thinning or can without soil Cultivated area reduces, and causes grain drop in production.Cattle is ploughed and turns over automatic seeder on lever, except alleviating the pulling force of cattle, automatic fertilization sowing Outside raking the soil level, it is also possible to plough clean pull from floor, can uniform soil thickness.

Technical scheme: cattle is ploughed and turns over automatic seeder on lever and be made up of 4 parts, 1. lever plough.2. seeder.3. rake.4. Plough arm front portion turns to.1. lever plough, old-fashioned plough former state is constant, and the plough of change is curved is to separate with plough arm intersection, ploughs curved tail Extending 10-15 centimetre is resistance section, and a pole is push rod, and one is fixed on poppet back below colter, and one passes resistance Duan Duan, head stretch out resistance section outer (formed the plough i.e. resistance section of curved tail can upper and lower activity, above have push rod cap to keep off, under have horizontal stripe to hinder).Plough Curved front end is force, plough curved intersect with plough arm hit exactly after to have a rod be fulcrum, after have activity to wear groove, resistance section is pressed over Being resistance point on push rod, a lever mechanics framework is formed.When the curved front end of cattle hauling plough (force), rod fulcrum and the (resistance of resistance section Force) stress simultaneously, plough curved straight front portion (power arm) more than resistance section (resistance point) 4 times, the power of three times of having saved your breath is for leaning on Bar (fulcrum) and resistance section (resistance point).By force backward, resistance section (resistance point) is forced through push rod with directly to rod (fulcrum) Try hard to recommend dynamic ploughshare forward.

Rod (fulcrum) is kind of a counter-force backward by force, is resistance in arable land, it should cutting down, scheme is: rod two is stretched Going out to plough 3-4 centimetre of arm, ploughing arm and ploughing below curved intersecting on plough arm, average 8 cm one section trisects, and every section above With relative below piece cross bar of each weldering, be push rod, upper two-section bar is long 18-20 centimetre, and rear one section of bar is shorter 6-8 centimetre, bar two Head has spring (stronger) respectively to hand over piece steel wire of strand (relatively slightly, can bear certain pulling force), left side rod two at rod two The root steel wire (being twisted into two to friendship in a steel wire) the above, below push rod head to the right hands over extension to go, the right rod two to Left side above, below push rod head hands over extension to go, above two steel wires intersect two push rods, following two steel wires and intersect two push rods, Finally all it is connected on the spring of a rear push rod.This is the straight power of the straight line according to mechanics (complete power), meander line Qu Li (consumption Subtract power) this principle, it is finally positioned on spring, cuts down the opposite force going rod, I thinks deduct 70% power, this It is many that the pulling force of sample cattle should alleviate half.

2. automatic seeder.

Seeder design is ploughed on one side on crosspiece, has individual flatrack above, piece rotating shaft of flatrack front central, and rotating shaft is Inner end is sowing fertilizers section, above has fertiliser bucket, about fills about two kilograms, is that Wheat Species sows section against centre, has Semen Tritici aestivi above Seed bucket, about fill about two kilograms, be Wheat Species sowing section against centre, have wheat seed bucket above, little about fill one kilogram.Turn Axle front portion is connected on the bearing before flatrack, rotating shaft end is runner；Crosspiece subcenter has plough to buckle.Cross other one of plough button side The pole of crosspiece, two is stretched out outside crosspiece, and connecting above to have in upright insertion tube, insertion tube has inserted link, flatrack back just to connect It is connected on (activeness) on inserted link head.Whole flatrack runner on the front and the highland of inserted link height below are supported on crosspiece Face.Have at the sub-two ends of crosspiece each 1/3 cross bar from there through crosspiece, two cross bar heads have up-and-down rod, cry block bar, act on be Limit sowing frame i.e. flatrack and can only be afraid of to block power not enough in railing, add one outside bar and lean to bar blocking again.

When cattle hauling plough is ploughed, runner rotates forward on the face of front cultivated soil, and the fertilizer in bucket is having turning of a plurality of scraping article Before on axle, the lower fertilizer of scraping is fallen below plough half way up the mountain soil, in little bucket, wheat seeds are having seed in 2-3 the rotating shaft planting cave to have fixed number Ground turns to fall on front plough soil half way up the mountain, says from position, and fertilizer buries deeply, and Semen Tritici aestivi buries more shallow, and it is recessed for turning over the native face ploughed through Convex injustice so that runner rise and fall activity.Fortunately it is that activeness is connected with inserted link after flatrack, due to the obstruction of railing, flat Frame can only upper and lower activity.

Separately there is a kind of seeder, apply to dibbling Semen Maydis, Semen arachidis hypogaeae, Semen sojae atricolor.Semen Tritici aestivi is heavy seeding type, Semen Maydis, Semen arachidis hypogaeae, big Bean is light seeding type, and Inner Constitution is different, and the overwhelming majority component of light seeding type in fact is the same, only adds below at bearing 25 Two wheels that rubber strip is connected, the tumbler having recalled sowing and fertilising is placed on before in the middle of two-wheeled in frame basket, first Bigger wheel is combined in rotating shaft, and the rubber strip of two wheels is pricked equidistant two scraping blades, (adjusts according to different seeds Whole distance, if Semen Maydis nest is away from being 30 centimetres, moveable small wheels abduction is to 30 centimeters, and rubber is with kind of a Telescopic fortunately ), before have three kind caves and three fertilizer caves on tumbler, (because of seed cave the most of the same race have size point), this head of tumbler It is inserted with three axostylus axostyles, corresponding three kind caves, three fertilizer caves on axle, when runner rotates, when scraping blade forwards the axostylus axostyle stood to, scrapes Sheet pushes over axostylus axostyle, and just tumbler kind cave and fertilizer cave overturn a brood of maize seed (2-3 grain) and appropriate amount fertilizer, and the next one is scraped When sheet pushes over second axostylus axostyle, the second nest maize seed and fertilizer sows, the most repeatedly.Here there is individual lime light: axostylus axostyle position is high Low suitable, scraping blade can only can push over axostylus axostyle on rubber strip top, and bottom just can be avoided.

3. rake, rake energy level land broken bulk soil, seed can be covered.Here rake is the least, is allowed to dry on the native face that plough rollover is ploughed, long Square, rake fourth before 3, after 4, long 7-10 centimetre, front crosspiece is blank pipe, rake bracing wire one be connected to the sub-head of crosspiece End, one is connected to harrow front middle part, harrows and cylinder is located to be connected with harrow frame (activeness) after rake is center deviation, and a rake barre exists Plough curved rear portion stretch out, head leading portion inject rake in cylinder, have set bridge, a stage casing to have cross bar two of end nest to stretch out rake handle in cylinder Cylinder outer (having in the middle part of cylinder longitudinally wearing seam), nest both sides, the end connect to be had on telescoping adhesive tape, and adhesive tape end stretches out from above and is connected to cylinder outside cylinder On outer hyphen bar, rake barre inserts head in cylinder and is against in cross bar on end nest.Plough is curved to swing constantly, and that is to adjust The depth of plough and upset earth, when plough body swing plough under curved rising press, end nest also and then rise under adhesive tape telescopic action under press, Remain the pressure to rake and orientation distance, the draught line of rake is oblique, easily pulls to ditch dug with a plow, and raking arm can position critically important, Another harrows two, outside rake fourth sheet shapes, and it slightly outwards partially can draw rake layman in traveling, has counteracting to pull strings interior oblique effect.

Semen Tritici aestivi disseminates (i.e. heavy seeding), and reserved row broadcasts dividing of (i.e. staying and plant between season), disseminates often to plough and all sows, and reserved row is broadcast Plant 2-3 to be stopped and plough line-spacing, save trouble for convenience, added an inclined frame in railing upper end, only flatrack head is lifted and be partially a little placed on Partially just may be used on frame.Runner leaves ground and does not rotate seed fertilizer and will not fall, and the most also can be placed on one side.Additionally on ploughshare and moldboard On all have the bar ridge, be anti-soil with ploughshare and plate closely paste wiping, closely patch wiping makes plough weight the most stagnant.Connecting rod is to connect to plough curved and plough arm , above there is movable coulisse.

4. plough arm front portion turns to: ploughs arm front portion and is i.e. positioned at after moldboard, disconnects, and connects one section in the weldering of upper incision position and breaks less than front The pipe of mouth, before inserting in disconnected QC, on lower incision position, impartial brings up five longitudinal cracks with easy accessly, Long 3-4 centimetre, on the tubule of new weldering, center is longitudinally welded with three vertical sheets, needs to adjust three vertical sheets according to arable land deflection and inserts Entering lower stony fracture seam, such as plough the clean pull from floor right side, three cracks on the right of three vertical sheets insertions, plough the clean pull from floor left side, three vertical sheets are inserted Entering the left side three crack, such arable land can overturn as level land smoothly, splits as the vertical sheet in three, level land to be ploughed inserts middle three Seam just may be used.

Below incision position, there is link position (activeness), link position is connected to a pike pole, leans in resistance section Three the oblique grooves having 4 ridge of the company of weldering to be formed at plough arm, have three of weldering 4 rule ridge formation even at resistance section arm rest Oblique groove.Pike pole set is hung on groove, effect be connect firmly disconnect before ploughshare portion.In resistance section, bar is taken off during transposition Hook, hitches pike pole again after transposition, transposition turns to pike pole distance to be intended to change, three grooves in resistance section be for Three transpositions, three distances and set, fit benefit.

Ploughing and be intended to conversion direction back and forth, seeder and rake also and then to turn to.Method is: before turning plough, raking arm From rake, cylinder being taken out, take off that of rake bracing wire, i.e. transom head, when turning plough, people from arable land drags on the other hand and turns plough, holds rake on the other hand, After farm cattle is become a full member, rake is put on cultivated soil, first turns over rake barre (activity), injects rake in cylinder.Again seeder is taken out and adjusted Head is put in crosspiece other end (i.e. plough soil face).Afterwards rake bracing wire is connected to this head of crosspiece, the most individual process row again will be experienced and plough Ground, ploughs the earth certainly, and the progress that saves trouble faster longly.

Cattle arable land shortcoming is intended to two, ground of backsetting, and disseminates the easy to handle program request in the same old way of wheat field.And reserve row ground to plough up After have to manual dibbling.

Beneficial effect: 1. lever plough can slow down at least half of pulling force of cattle, can plough more one times to doubly, the most automatically broadcast Planting, apply fertilizer, automatically rake the soil level and imitate raising 2-3 times before speed ratio, save labour more than 10,3. seed energy is quantitative, broadcast fertilizer energy deep placement, cultivated Ground can keep loosening the soil always (people cattle does not treads on) can produce more food.4. clean pull from floor can be ploughed in hillside fields.

Detailed description of the invention: cattle is ploughed lever automatic seeder and is made up of 3 parts, 1 lever plough, 2 seeders, 3 rakes.4 plough arms Front portion turns to.

1, lever plough: old-fashioned plough 1 former state is constant, the plough of change is curved is to separate with plough arm intersection, ploughs the elongation of curved tail 10-15 centimetre is resistance section, and a pole is push rod 15, and one is fixed on below colter after poppet, and one passes resistance section End, head stretches out resistance section outer (resistance section can be up and down, above has nut to keep off, under have horizontal stripe to hinder).Ploughing curved front end is force, ploughs curved Intersecting with plough arm after hitting exactly that to have a rod 21 be fulcrum (groove is worn in activity below), it is resistance that resistance section is pressed on push rod 15 Point, a lever mechanics frame is formed.When the curved front end of cattle hauling plough (force), rod 21 and resistance section (resistance point) stress simultaneously, plough Curved (power arm) is more than resistance section (resistance point) 4 times, saves your breath and also has the power of 3 times to act on rod (fulcrum) and (resistance of resistance section Force), by force rearwards, resistance section (resistance point) is forced through push rod 15 and forms promotion turnplow forward with straight power rod 15. Rod 21 fulcrum is opposite force backward by force, is resistance in arable land, it should eliminate or cut down, and scheme is that rod 21 two is stretched out 3-4 centimetre of arm of plough, is ploughing arm and is ploughing below curved intersecting on plough arm, and average 8 cm one section trisects, and each section above A piece cross bar of each weldering, is push rod 32 relatively below, and upper two-section bar is long 18-20 centimetre, and a rear truncation bar is shorter 6-8 centimetre, top Head has spring (stronger to), respectively hands over a piece steel wire (more slightly can bear certain pulling force) of strand, left side rod at rod 21 two 21 two steel wires (hand in the middle of a steel wire and be twisted into two) above the right, below push rod 32 hand over extension to go, the right rod 21 two steel wires above the left side, below push rod 32 hand over extension to go, above two steel wires intersect two top thick sticks 32, below two Root steel wire two push rods 32 of intersection, after the most all connecting on the spring of push rod, this is the straight power of the straight line according to mechanics (complete power), Meander line Qu Li (reduction power) this principle, spring 14 also cuts down the opposite force of rod 21, and I thinks cut down 70%, So should to alleviate half many for the pulling force of cattle.

2, seeder: seeder design is ploughed at crosspiece 3, has individual flatrack 11, flatrack 11 front central one above According to rotating shaft 9.Rotating shaft 9 innermost end is sowing fertilizers section, has fertiliser bucket 7, about about 2 kilograms of fertilizer of dress above, against centre is Wheat Species sowing section, above has Wheat Species bucket 8, about fills 1 kilogram, and rotating shaft 9 front portion is connected on the bearing 25 before flatrack 11, rotating shaft 9 ends are runners 10.There is plough button at crosspiece 3 centers, and at the other pole crossing crosspiece 3 in plough button side, crosspiece 3 is stretched out at two Outward, connect above to have in upright insertion tube 6, insertion tube 6 and have inserted link 5, flatrack 11 back to be just connected to the upper (activeness of inserted link 5 ), whole flatrack 11 runner 10 on the front and inserted link 5 below high be supported on above crosspiece 3, crosspiece 3 two ends At each 1/3, having cross bar from there through crosspiece 3, two cross bar heads have up-and-down rod on railing 4, and effect is to limit flatrack 11 Can be afraid of to block power not enough in railing 4, add one outside bar 4 and lean to bar blocking again.

When cattle hauling plough is ploughed, runner 10 rotates forward on the face of front plough soil, the fertilizer (combined type chemical fertilizer) in bucket, Before having in the rotating shaft 9 of a plurality of scraping article 23 fertilizer of swiping to drop to below plough half way up the mountain soil, little bucket wheat seeds are having 2-3 the rotating shaft planting cave On 9, definite turn falls on front plough soil half way up the mountain, says from position, and fertilizer buries deeply, wheat seeds bury more shallow, turns over and ploughs through Soil is uneven so that runner 10 rise and fall activity, is that activeness is connected with inserted link 5 fortunately, due to railing 4 after flatrack 11 Stopping, flatrack 11 can only upper and lower activity.

Separately having a kind of seeder, apply to dibbling Semen Maydis, Semen arachidis hypogaeae, Semen sojae atricolor, be light seeding type, Semen Tritici aestivi is heavy seeding type, big portion It is the same that part is constituted, and simply light seeding type adds, at bearing 25, two wheels that adhesive tape 27 is connected below, has recalled sowing and has executed Fertile tumbler 30 is placed on before two-wheeled centre in frame basket, and first bigger wheel 26 is combined in rotating shaft 9, two wheels Prick on adhesive tape 27 and have equidistant two scraping blades 27 (to adjust distance according to different seeds, if Semen Maydis, nest are away from being 30 centimetres, can move Dynamic small wheels 28, abduction is to 30 centimeters, and adhesive tape 27 has Telescopic fortunately), tumbler 30 has three kind caves and 3 fertilizer Material cave (because seed is different, planting cave has dividing of size), this axle of tumbler 30 is inserted with corresponding three the kind caves of an axostylus axostyle 29 With 3 fertilizer caves, when runner 10 rotates, when scraping blade 27 forwards stand axostylus axostyle 29 to, scraping blade 27 pushes over axostylus axostyle 29, just tumbler 30 Planting cave and fertilizer cave is turned to lower a brood of maize seed (2-4 grain) and suitable fertilizer, next scraping blade 27 pushes over second axostylus axostyle 29 Time, the second nest Semen Maydis and fertilizer are sowed, and the most repeatedly, have individual lime light here, and 29 height of axostylus axostyle are wanted suitably, and scraping blade 27 can only Scrape beaming bar 29 above, the most just can escape.

3, rake: rake 16 here is the least, be put in plough rollover plough soil on, long square, rake fourth before 3, after 4, Fourth is long 7-10 centimetre, and front cross member is blank pipe, harrow 16 bracing wire 12 1 is being connected to crosspiece 3 head ends, one in rake 16 front ends, Harrowing and cylinder 18 is located to be connected (activeness) with harrow frame 16 after rake 16 center deviations, a rake barre 22 stretches out at the curved rear portion of plough, head Leading portion injects rake in cylinder 18, has and overlap bridge 19 in cylinder, and there is the cross bar of end nest in stage casing at the bottom of frame, and two stretches out at cylinder that (cylinder has Longitudinally to wearing seam), nest both sides, the end connect telescoping adhesive tape, and adhesive tape end is connected at cylinder on hyphen bar at top is stretched out tin, rake In barre 22 inserts cylinder, head is against on nest.Plough body swings constantly, and that is to plough soil in the depth and upset adjusting plough, Press down end nest to press under also and then rising under the effect that adhesive tape stretches when plough body swings the curved rising of plough, remain the pressure harrowing 16 And orientation distance, the bracing wire of rake 16 is oblique, easily pulls to ditch dug with a plow, and rake barre 22 can position critically important, and another harrows outside 16 There is both direction sheet 17 (rake fourth) side, and it slightly outwards tiltedly, draws rake 16 layman in moving ahead, and tiltedly acts in having counteracting two bracing wires.Little Wheat is disseminated (i.e. heavy seeding), and reserved row is broadcast (i.e. stay between season plant) two kinds and broadcast method, disseminates often to plough and all broadcasts, and reserved row sowing to stop 2-3 row is just broadcast, and for convenience, has added an inclined frame 2 in railing 4 top, only flatrack 11 has been lifted and be partially a little put in inclined frame 2 just Can, runner 10 leaves ground and does not rotate seed fertilizer and will not fall, naturally it is also possible to takes off and puts on one side, puts sowing time again.

It addition, have the bar ridge on ploughshare and moldboard, it is that the anti-consolidation patch ploughing soil and ploughshare and moldboard is wiped so that plough increases heavy burden, even Extension bar 20 is to connect to plough curved and plough arm, i.e. separates and links together, having chute after connecting rod 20, and when ploughing curved stress, it is just gone up Sliding, the most just lose lever augmented.

Ploughing and be intended to back and forth to turn to, seeder and rake also and then to turn to, and method is before turning plough, rake barre 22 is from rake Taking out in cylinder 18, take out that of external cable 12, when turning plough, people from arable land drags on the other hand and turns plough, a hand-held rake 16, and plough, cattle turn After ajusting, rake 16 is put in arable land in situ, first turns over rake barre 22 (movable), inserts rake in cylinder 18, then by seeder Flatrack 11 taking-up tune is excessive is put in the other end of 3 on crosspiece, and inserted link 5 reinserts in insertion tube 6, and bracing wire 12 is connected to crosspiece Son 3 that, this process to be experienced and could go arable lands again, certainly plough the earth, long more save trouble, progress soon, cattle arable land shortcoming Be intended to backset two, ground, disseminate that wheat seeds are easy to handle to be sowed in the same old way.And backup land have to plough rear manual dibbling to up.4, plough arm Front portion turns to, and plough front portion is i.e. positioned at after moldboard, and disconnection above, brings up 5 longitudinal cracks 34 at epimere mouth equably, long 3-4 centimetre, on the tubule of new weldering, center is longitudinally welded with 3 vertical sheets 33, needs to adjust 3 vertical sheets 33 according to arable land deflection and inserts Enter following crack 34, plough 3, clean pull from floor left side sliver 33 and insert the left side 3 crack 34, so plough and can turn over smoothly as level land Turning, such as level land to be ploughed, 3 vertical sheets insert middle 3 cracks 34 just may be used.

Link position, link is had to be connected to (activeness) pike pole 35 on position, in resistance section below incision position By 3 the oblique grooves 36 having weldering 4 rule ridge even to be formed at plough arm, pike pole 35 set is hung on groove 36, and effect is to connect firmly to break Ploughshare portion before opening.Taking off pike pole 35 during transposition in resistance section, hitch pike pole 35 after transposition again, transposition turns to pike pole 35 Distance is intended to change, and 3 grooves 36 in resistance section are for 3 transpositions, 3 distances and set, fit benefit.
