Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Please refer to Fig. 1-Figure 10, the wear-resisting tractor-ploughing floor of the bionical multistage form Anti-erosion of one kind provided by the invention
Some embodiments.
As Figure 1-Figure 2, the present invention provides a kind of wear-resisting tractor-ploughing floors of bionical multistage form Anti-erosion, comprising:
Bottom plate ontology 3 and several meniscus elements 33 that 3 lower surface of bottom plate ontology is set, several described meniscus elements 33
It is arranged along the driving direction interval of the bottom plate ontology 3；Each meniscus elements 33 include: convex closure array 331 and V-shaped groove
332, the convex closure array 331 is located at the V-shaped groove 332 along the driving direction side of the bottom plate ontology 3, that is, is located at the V
The side opposite with boat tractor fore of shape slot 332.
Bottom plate ontology 33 is usually located at the bottom of boat tractor, and bottom plate ontology 3 uses ship type sole.In addition to bottom plate ontology 3, machine
Plough ship further include: directive wheel 1, traction hook 2, engine 4, transfer 5, gear lever 6, seat 7, sunshade 8, hydraulic lifting
Device 9, cultivating apparatus 10, brake apparatus 11, rear wheel 12, gearbox 13.Wherein, the purpose of design master of boat tractor shape hull
If increasing the contact area between fuselage and working media, weaken the forward resistance of boat tractor farming in paddy field, improves machine
Ship is ploughed in the stability and steering manipulation ability of farm work, realizes energy consumption saving and high efficiency operation.
When boat tractor works normally, in soil there is very big shadow to boat tractor ship shape shell in complicated liquid-solid two-phase operating condition
It rings.Firstly, the gravity pressure of fuselage will be so that hard when the hard particles or hard protrusion in field soil contact ship type sole
The speed that matter particle is advanced with boat tractor does relative motion with ship type sole.This relative motion meeting is so that ship type sole exists gently
Micro- long and narrow scratch, these scratches gradually will grow and spread under the conditions of continuing working, and be eventually exhibited as in ship type sole table
There is long and narrow deep ditch dug with a plow and cutting slot in face, develops into crack, gradually cuts and wear bottom plate, causes boat tractor that can not carry out field and ploughs
Make, delay farming season, increases maintenance cost.On practical implementation, crackle is cause material or device fracture failure great
One of reason.Secondly, the liquid environment in southern red soil be mostly it is acid and it is a kind of accelerate that scratch extends it is main because
Element.
It is worth noting that several meniscus elements 33 are arranged along the driving direction interval of bottom plate ontology 3 in the present invention.One
Aspect, forms vortex when water slug meniscus elements 33, and the vortex of convolution increases the turbulent extent of water, changes bottom plate ontology 3
The motion profile of hard particles in neighbouring water flow field specifically becomes the straight-line trajectory of hard particles impact bottom plate ontology 3
At the motion profile of vortex type curve, the probability of hard particles collision bottom plate ontology 3 is not only reduced, hard particles are also reduced
Collide the impact velocity of bottom plate ontology 3 (speed here refers to speed of the hard particles relative to bottom plate ontology 3, similarly hereinafter).Separately
On the one hand, meniscus elements 33, which make 3 surface of bottom plate ontology form non-smooth surface, has the function of anti-sticking drop resistance, reduces bottom plate sheet
The forward resistance of body 3.
A convex closure array 331 and a V-shaped groove 332 constitute a meniscus elements 33, and convex closure array 331 in the present invention
Positioned at V-shaped groove 332 along the driving direction side of bottom plate ontology 3.Boat tractor when driving, convex closure array 331 is in preceding, V-shaped groove 332
Rear.Since water or hard particles first contact convex closure array 331, rear to contact V-shaped groove 332, hard particles are in convex closure array 331
Under the influence of reduce speed, even if collide, and damage convex closure array 331, bottom plate ontology 3 will not be damaged.
And can change the erosion angle of hard particles in convex closure array 331, hard particles are substantially reduced to bottom plate sheet
The impact force of body 3.As shown in fig. 7, hard particles when impacting convex closure 3311 with speed v, form erosion area I and erosion area
II, erosion area I are by larger Ground shock waves, and erosion area II is by lesser impact.For toughness material, when impact angle is
At 20-30 °, erosion rate is maximum.When hard particles impact bottom plate ontology 3 with the impact angle of θ (for example, 20-30 °), convex closure
3311 curved surfaces can increase impact angle in θ ' or θ ' ', naturally it is also possible to reduce impact angle, therefore, also reduce
Erosion of the hard particles to convex closure 3311.
For hard particles after the direct action that have passed through convex closure array 331 when colliding V-shaped groove 332, V-shaped groove 332 is right
Hard particles carry out secondary action, due to having synergistic effect between convex closure array 331 and V-shaped groove 332, in convex closure array 331
It is formed on the basis of vortex, V-shaped groove 332 is more likely formed vortex, is more convenient for changing the track of long and narrow scratch.As shown in figure 9, hard
Ditch dug with a plow that particle generates on bottom plate or cutting scratch 15 are discontinuous, weaken hard particles to the abrasive action of bottom plate, while V-arrangement
The ditch dug with a plow or cutting scratch 15 that slot 332 is also formed hard particles on the surface play the role of interception, steering, prevent ditch dug with a plow or
It cuts scratch 15 further to extend and extend, therefore effectively reduces bottom plate wear rate, to improve the service life of boat tractor.
Furthermore compared to plane, V-shaped groove 332 also acts as the effect for changing hard particles erosion angle, as shown in figure 8, impact angle θ is increased
Greatly θ ' ' '.
In addition, convex closure array 331 and V-shaped groove 332 also increase the contact area of bottom plate ontology 3 Yu liquid phase of soil, reduce
Forward resistance, convex closure array 331 also increase the intensity of bottom plate ontology 3.
In nature, shell, desert scorpion are the canonical biometrics with Anti-erosion abrasive resistance.Wherein, long-term raw
Usually there is complicated body surface pattern there are the shell in sea sand shock environment, this pattern shows good Anti-erosion and resistance to
Grind characteristic.Such as piddock, stone razor clam, blood clam can dig stone, wear wood, bore sand, and this excellent Anti-erosion wear-resisting property is to a certain degree
On have benefited from the channel form structure of its body surface.And scorpion existence is often accompanied by sandstorm weather in the desert Environment of bad environments.
But the sand impact of high-speed motion is very little to the damage of desert scorpion.This result has benefited from desert scorpion body surface backboard V
The excellent body surface form such as shape slot, convex closure.Anti-erosion Wear-resisting bottom plate multistage configuration of surface includes convex closure and V-shaped groove two in the present invention
Kind morphosis, can also be arranged regular hexagon bowl configurations certainly.
The wear-resisting tractor-ploughing floor of bionical multistage form Anti-erosion provided by the invention, due to utilizing convex closure array 331 and V-arrangement
Synergistic effect between slot 332 reduces the impact velocity of hard particles, changes the erosion angle of hard particles, changes long and narrow
The track of scratch reduces the wear rate of bottom plate, can be conducive to improve the service life of boat tractor.
