Description
Technical field
The invention belongs to agricultural machinery technological fields, and in particular to a kind of multi-blade high speed rear digging machine.
Background technique
The existing rear digging machine with the four-wheel tractor of 50-100 kilowatts of power, is commonly called as large and medium-sized ditching machine,
General weight is all at 300 kilograms or so, and the cutterhead revolving speed of ditching machine is about at 260 turns per minute or less；Production and application has surpassed so far
30 years or more history is crossed, and to not there is change substantially at present, basic structure is as follows：
It is mounted in the middle part of rear tractor by front, ditching machine of tractor direction of advance, observer stands in tractor and trench digging
Machine rear portion its integral structure layout of the view towards ditching machine：The rack of ditching machine is by two stringers in left and right and front and back two
One general frame type structure being rectangle of root crossbeam composition；It about 50 centimetres of the cutter radius of ditching machine or so, vertically sets
It sets in frame-type rack, cutter axis is passed through from cutter head center, is transversely and horizontally set in two stringers of frame-type rack or so
Top, i.e., plane is located at cutterhead axis center or less in frame-type rack；When trench digging, there are about 25-30 centimetres of entrance for cutterhead lower half circle
In soil, under job state, frame-type rack bottom margin ground location is very low, the height less than 20 centimetres or so.Ditching machine
Gear-box is assemblied in the stringer top on the left of rectangle frame-type rack with several bolts.Driving shaft on gear-box（I.e. power is defeated
Enter axis）Extend forward and couple with universal joint telescopic shaft and universal joint casing, universal joint casing is across the front beam in front of rack
Top couples with the universal joint of the power output shaft at tractor rear portion forward, driving shaft on gear-box and installed with it ten thousand
On the stringer being located on the left of rack to section telescopic shaft and the front beam in front of rack；Cutter axis left end is inserted into gear-box,
It is assembled in a manner of spline with driven big angular wheel, after cutter axis right end projects through cutterhead from gear-box, cutterhead shaft end is used
Bearing and bearing block are mounted in frame-type rack right-hand stringer；Cutterhead makes of thick steel plate, and cutterhead edge has 12 to cut native knife
Piece；It is provided with arch door shape earth separation plate above cutterhead, earth separation plate front and back end is fixedly connected with the crossbeam of rack rear and front end.After cutterhead
Lower section is provided with perching knife, and the rear cross beam of perching knife and ditching machine frame-type rack is fixedly mounted, and the lower cutting edge of perching knife is close to when trench digging
Bottom of trench, to root out the knoll of bottom of trench surflaes or bottom of trench protrusion.
The yield of grain is improved due to pursuing in recent years, the requirement to agronomy is more accurate, especially also wants after planting
The process for increasing covering and suppression, therefore the effect of ditching machine is not only for digging trenches to drain the water away, it will also be after the soil chopping in ditch
It uniformly sheds on farmland surface after planting, it is overwintering to protect seed to keep warm.
But the ditching machine of the prior art is not since its structure is improved for many years, and there is following disadvantages：
It 1, has been using step-down ratio always in gear case of ditcher between 1 in many decades since ditching machine is born:
3.3 to 1:Between 3.5.It is provided with sum on cutterhead it is usually 12 and cuts native knife this has become a kind of convention.Since cutterhead turns
Speed is low, and blade on cutterhead is again on the low side, therefore in the on the low side apart from number of the inner blade to soil cutting of certain forward speed, from
And make the soil layer thickness of blade cut, soil block thick；Another low consequence of cutterhead revolving speed is to throw soil apart from short, the ground of close limes marginis
The soil layer just shed is thick and more, and thin even without soil away from the farther away local soil layer of ditch, distance is shed unevenly, cannot be covered comprehensively
The possible exposed seed on ground, influences crop yield；
2, again because prior art cutterhead revolving speed is low, knife number is few, and the blade frequency for cutting bottom of trench is few, a large amount of surflaes in ditch
It not can effectively clear, in order to solve this problem, the prior art can only rely on the perching knife being arranged under rear cross beam will be residual in ditch
After mamoty is scraped, then dished out to outside ditch from the blade on cutterhead.Since ditch depth is unstable etc., factors, perching knife and bottom of trench shovel scraping force are excessive
When, very big torque can be generated to rack；Again since cutterhead revolving speed is low, knife number is few, and the soil layer of blade cut is thick, leads to list
The cutting resistance of a blade is big, also can generate biggish impact force to cutterhead and cutter axis；So the ditching machine machine of the prior art
Frame, could powerful support and the trench digging that contends with usually with the stringer of left and right two and the integral frame-like structures of crossbeam soldering of front and back two
The blade cut soil and perching knife of machine knife disk shovel the strong impact power scraping bottom of trench and generating；And general frame type rack is also inconvenient
In the dismounting of cutterhead；The gear-box and bearing of cutter axis two sides are set due to two stringer parallel arrangements in the prior art
Seat；Cutter axis both ends, cutterhead two sides will have bearing and bearing seat supports, and cutter axis left end is inserted into gear-box, cutter axis
Right end from gear-box project through cutterhead after end bearing and bearing block be mounted in frame-type rack right-hand stringer, cause knife
Disk can not dismount；And each component such as rack and cutterhead requires to be made to coarse heaviness, so complete machine is not easy to dismounting, maintenance
And transport；
3, again since the rectangular frame type rack of two stringer parallel arrangements forms the fence of closed, and apart from ground position
It sets lower, is in cutter-head of machine for making furrows and is thrown in the main path of soil outward, seriously hinder that soil block is outside to be shed, so that native
Block harmony is got lodged in frame-type rack, can not be dished out outward, especially also will cause when operation in the strong soil of moist, adhesiveness
Blocking falls in ditch after the soil block accumulation of blocking is agglomerating, increases surflaes in ditch, be unfavorable for draining；Engine load simultaneously
Also big；
4, in the prior art, gear-box is assemblied on a side frame stringer, and the cutter axis insertion of cutterhead side is mounted on gear-box
It is interior, by two bearing supports at gear chamber interior wall both ends；It stretches out the other end of the cutter axis of gear-box after cutterhead and uses axis again
It installs in the bearing block fitted on the side frame stringer；Since two stringers of ditcher rack are that soldering forms, precision is very poor,
The concentricity of three bearings on cutter axis is not can guarantee；After tightening the bolt on bearing block, cutter axis and bearing can be generated
Very big moment of flexure and the larger pressure to bearing generated by moment of flexure increase cutter axis rotary resistance, can damage when serious
Bearing.Using it is this it is unreasonable on a cutter axis with the reason of three bearing supports be because furrow-opening cutter blade cut soil
Impact resistance it is big, biggish torque and moment of flexure can be produced to cutterhead and cutter axis, two bearings cannot be born in gear-box
The load of cutter axis haves no alternative but the cutterhead other side cutterhead shaft end just outside gear-box and increases a bearing support, could bear
The load generated when trench digging；
5, the ditching machine of the prior art generally weighs 300 kilograms or so, and being articulated in behind tractor will lead to lifts on front-wheel, front
The effect of hoofing part wheel drive force cannot play, unbalanced in order to solve the problems, such as, two are loaded onto front of tractor
More than totally five hundred kilograms of weight is pressed in the walking tire at four-wheel tractor rear portion mostly for more than hundred kilograms of counterweight iron block, in this way front and back
On, keep it excessive to the pressure on ground, soil is caused to be rolled excessively hardened, also will form deeper rut, be unfavorable for agriculture
The growth of crop, farmland also out-of-flatness, such as operation can also make under tractor driving wheel in the higher wet field of moisture content
Fall into too deep, load seriously increases so that can not walk.
Summary of the invention
The purpose of the present invention is to provide a kind of multi-blade high speed rear digging machines, will solve existing ditching machine and cut
Soil block it is coarse not fine crushing, cannot uniformly shed, the gap on rotary tillage soil layer surface before can not being filled up completely；Soil block is overcome to shed
The problem of not far, wet field blocks seriously, and blade cut resistance is big, engine load exacerbation；The low bank of earth between fields that limes marginis is easily accumulated is eliminated,
Surflaes is more in ditch, hinders surface water and flows into ditch, is unfavorable for the situation of draining；Simultaneously solve it is bulky, heavy, transport,
Dismounting, maintenance are inconvenient and bring tractor rear portion traveling wheel because of heavy face pressure is powerful over the ground, leads to dry ground soil pressure
Hardened, wet field easily sink a series of disadvantage such as cause tractor load big.Prioritization scheme can also solution must not sufficiently cover
The lid seed sowed of protection against winter severe cold frostbite, be unfavorable for the heat preservation growth of overwintering crops such as wheat, rape from
And the problem of influencing yield.
The technical scheme is that：A kind of multi-blade high speed rear digging machine, mainly by rack（Including rack stringer
With rack front beam etc.）, gear-box, driving shaft, universal joint telescopic shaft, cutterhead, earth separation plate etc. constitute, it is characterised in that：Run through
The shaft end portion of cutterhead is not provided with bearing out；It is provided with sum on cutterhead and cuts native knife and total not less than 8 cliff knives not less than 12
Not less than 20 blades；Using step-down ratio between 1 in gear case of ditcher:1.3 to 1:A pair of of bevel drive between 2.8
Gear slows down with driven bevel gear wheel.
Further improvement of the present invention has the following optimization options：
It is provided with sum on cutterhead and cuts native knife and not less than 8 cliff knives are not less than 20 blades altogether not less than 12, especially
Refer to that 16 that the present invention uses are cut native knife and 8 cliff knife sums totally 24 blades；Cliff knife handle on cutterhead is arranged in wheel rim
Outside, cliff knife can move on cliff knife handle to adjust trench digging width left and right directions.
11 tooth bevel pinions and 26 teeth also can be used in bevel drive pinion and driven bevel gear wheel in gear case of ditcher
Bevel gear wheel be meshed 1:2.36 transmission ratio slows down, or is meshed using 12 tooth bevel pinions and 27 tooth bevel gear wheels
1:2.25 transmission ratio slows down, or 1 to be meshed using 11 tooth bevel pinions and 27 tooth bevel gear wheels:2.45 transmission
Than slowing down, the existing ditching machine 1 of cutterhead rotating ratio:3.3 transmission ratio significantly improves 50%, and improving cutterhead revolving speed is to understand
Certainly soil chops up broken rear quality and lightens, and cannot cast necessary apart from this problem；Meanwhile it is more advantageous to improve cutterhead revolving speed
Cut fine crushing in soil.
Gear-box only couples with the assembly of the rack stringer of cutterhead side；The cutter axis and cutterhead for stretching out gear-box assemble.
In other words, the invention is characterized in that：
The present invention is using the quantity for increasing cutterhead cutter and reduces the transmission between bevel drive pinion and driven bevel gear wheel
Than greatly improving the technical solution of cutterhead revolving speed, while being conducive to expand the native distance of throwing and keep soil block fine crushing, and reducing
The thickness of blade cut soil horizon alleviates the impact load to cutter axis to reduce the cutting resistance of individual blade；It lengthens
The distance between two bearings in gear-box select biggish bearing, while cutterhead are abutted gear-box, to reduce cutterhead to knife
The moment of flexure of dish axle, also for cancel cutterhead on the outside of bearing and bearing block create condition.
After the bearing of one end of cutter axis is cancelled on the outside of cutterhead, two unexpected benefits are brought, first, cutterhead can
With convenient assembly or disassembly, convenient for tractor walking and ditching machine transport, maintenance；Second, it is originally used for the vertical of assembly bearing
Beam can be cancelled, and the obstruction that soil block is spread to this side throwing is completely eliminated.
After improving cutterhead revolving speed, the speed of soil block projectile is increased, expands the distance that soil block is shed.
The quantity for increasing cutting tip on cutterhead reduces the thickness of cutting of soil layer, makes soil in conjunction with the revolving speed for improving cutterhead
Block cuts more fine crushing, also reduces the cutting resistance of individual blade, reduces the shock loading to cutterhead, cutter axis.
It is rolled into circle with profiles such as round steel, square steel or band steels, steel pipe or round steel etc. make spoke, are made of welding procedure,
The wheel of similar bicycle, to mitigate cutterhead weight.
It is mounted on the rack stringer of side, cancels another by gear case of ditcher and with the cutterhead setting of its cutterhead axis connection
Installation bearing is no longer arranged in one side girder and the crossbeam at ditcher rack rear, the cutterhead shaft end that gear-box stretches out cutterhead,
Thus cutter-head of machine for making furrows is dismounted with can be convenient, convenient for the transport of tractor walking and ditching machine；The component of complete machine is simplified, greatly
Amount reduces the weight and volume of ditching machine, while sufficiently expanding the left and right side of cutter-head of machine for making furrows and front and mainly throwing native region
Throwing soil space, thoroughly eliminate the obstacle shed of soil block.
It is coarse not fine crushing that the present invention overcomes the soil blocks existing in the prior art cut, cannot uniformly shed, can not
The gap on rotary tillage soil layer surface before being filled up completely, and cannot the sufficiently seed sowed of covering protection against winter severe cold
Frostbite is unfavorable for the problem of heat preservation growth of overwintering crops such as wheat, rape is to influence yield；Prioritization scheme also solves
Crowded narrow space between the components such as frame-type rack and cutterhead, soil block are shed not far, and wet field blocking is serious, blade cut
The problem of resistance is big, and engine load aggravates；The low bank of earth between fields that limes marginis is easily accumulated is eliminated simultaneously, surflaes is more in ditch, hinders surface water
It flows into ditch, is unfavorable for the situation of draining；It is bulky, heavy to solve existing ditching machine, transport, dismounting, maintenance are inconvenient
Face pressure is powerful over the ground, rut partially dried ground soil pressing plate knot, wet field with tractor rear portion traveling wheel is brought because of heavy
It easily sink a series of disadvantage such as cause tractor load big.

Referring to Figures 1 and 2, a kind of multi-blade high speed rear digging machine, including rack（Before rack stringer 9 and rack
Crossbeams 4 etc. are constituted）, gear-box 11, cutterhead 12, earth separation plate assembly（Including upper earth separation plate 14 and lower substrate 15）Deng composition, gear
The inside of rack stringer 9 is arranged in case 11, and the driving shaft 8 of gear-box 11 passes through active shaft universal-joint 7 and universal joint telescopic shaft 5
It connects；Universal joint telescopic shaft 5 forward extends out below the front beam 4 in front of ditcher rack, with universal joint telescopic sleeve 2 and dilatory
Power output shaft 1 couples, rack front beam 4 is located at the top of driving shaft 8 of gear-box, straddles in driving shaft 8 and its couples
On universal joint telescopic shaft 5；
Referring to Fig. 2, the power output shaft of existing tractor is about 850 turns per minute, and the cutterhead revolving speed of existing ditching machine technology is every
Minute is 260 turns hereinafter, using 11 teeth in gear-box：A pair of of reduction gearing of 35 teeth, step-down ratio are 1:3.2；The present invention
Gear-box in using step-down ratio between 1:1.3 to 1:A pair of of bevel drive pinion 23 and driven auger tooth between 2.8
Wheel 24 slows down, and refers in particular to 12 tooth of tooth bevel pinion 23 and 26 bevel gear wheels 24 that the present invention uses are meshed 1:2.16
Reduction ratio slow down, cutterhead revolving speed is increased to 390 turns or more from 260 turns per minute or less of the prior art, improves revolving speed
1.5 again；Due to greatly improving for cutterhead revolving speed, makes to throw native distance and be increased to 2-3 meters from 1 meter or so of the prior art.
Referring to Figure 1 and Figure 3, the present invention has increased considerably the quantity of 12 cutter of cutterhead, and setting is total not on cutterhead 12
Native knife and 8 cliff knives totally 20 blades are cut lower than 12.16, which are used, in the embodiment of the present invention cuts native knife and 8 cliffs
Knife, including totally 8, left cut soil knife 29, totally 8, right cut soil knife 30, totally 4, left cliff knife 31, totally 4, right cliff knife 32, sum is altogether
24 blades.From 12 the right of cutter-head of machine for making furrows（It is axial）It sees, 16 are cut native knife and 8 cliff knives are divided into four groups and are uniformly distributed；From
Ditching machine rear sees that 16 are cut native knife from left to right and are divided into four-legs intersection setting cutting soil, is conducive to cut soil block
More evenly, while bottom of trench is also smooth；Each 4,8 cliff knives or so are uniformly distributed the side for being arranged in cutterhead outer rim.Due to blade
Sum greatly improves, and revolving speed improves 1.5 times again, so same forward speed increases 2 times apart from inner blade cutting quantity
More than, so that soil block be made to cut very fine crushing.Since the present invention using increase knife number and improves two kinds of skills of cutterhead revolving speed
The scheme that art combines also has the function of surflaes in very strong cleaning ditch, so that bottom of trench is very clean, obtains and unexpectedly " takes
Disappear perching knife " good effect, not only simplified structure, also reduced the load of cutterhead and rack；In addition increased cliff knife, solution
The rough disadvantage of the prior art of having determined furrow bank, and cliff knife or so is adjustable, and furrow width is adjustable.
From the soil block that repeatedly from the point of view of field is by the result of the prior art and comparative test of the present invention, existing ditching machine is cut
About 4.2 centimetres of average thickness, spread it is broken after maximum soil block weight be about 0.5 kilogram, wherein weighing about one gram less than 1 cubic centimetre
Soil block accounts for about 30%；And the average thickness of the ditching machine cutting soil block of the technology of the present invention is about 0.14 centimetre, maximum soil block weight is only
