Description
Technical field
The present invention relates to a kind of vibration rotary tillage facility, especially a kind of novel vibrating rotary tillage facility that are applicable to the small-scale agricultural machinery of tea garden management, mountain region operation.
Background technology
China is a large agricultural country, and present rural area generally adopts the regional mechanization degree of traditional tillage method, particularly tea garden management, mountain region operation lower, causes the big efficient of peasant's labour intensity low.Most facility are bulky on the market now, price is high, and it is suitable for the Plain; And the present special special running gear of rotovator needs drags and moves ahead, and labor fuel causes unnecessary loss in the process of dragging.
Summary of the invention
The present invention is directed to present rotovator specifically long-pending big, expend the energy and be inappropriate for the problem of mountain region operation, the novel vibrating rotary tillage facility that are suitable for mountain region operation and tea garden management that proposed that a kind of volume is little, power consumption is low, can produce vibrocutting.
Novel vibrating rotary tillage facility of the present invention; Comprise rotating mechanism and facility body; It is characterized in that: described rotating mechanism comprises the outer shaft of hollow, interior axle, compressing mechanism and cutter, and said outer shaft is connected with the power take-off of facility body, and circumferentially is furnished with installing hole; Axle is for being fixed on the camshaft on the inner axis of described outer shaft in described; Said compressing mechanism runs through and is installed in the described installing hole; Described cutter is fixed on the tail end of described compressing mechanism through pin;
Described compressing mechanism comprises that sleeve, tail end are provided with the push rod of connecting hole, are socketed in the spring on the said push rod of said sleeve inner, and said sleeve comprises cylindrical shell and the fixture that is positioned at the cylindrical shell bottom, and described pushing rod sleeve is connected on described sleeve inner; Be provided with the groove of mounting cutter along the axis of said push rod.
Said push rod length is greater than said length sleeve.
Described compressing mechanism is fixed on described fixture on the described outer shaft through nut.
The length of the outstanding said outer shaft inwall in described push rod top arrives the distance of said outer shaft inwall greater than the cam point of axle in said.
When facility were started working, power outputed to outer shaft, and outer shaft begins rotation; Because cutter is fixedly connected on the outer shaft; Cutter also follows suit and rotatablely moves, and in the rotary course, pushes between the flange of the top of compressing mechanism and interior axle; Thereby the part of pressurized compression spring drives cutter and in the rotary tillage process, carries out stretching motion, and then forms vibrocutting.
The invention has the beneficial effects as follows: volume is little, power consumption is low, can produce vibrocutting, be suitable for mountain region operation and tea garden management.

Embodiment
Further specify the present invention below in conjunction with accompanying drawing
With reference to accompanying drawing:
Novel vibrating rotary tillage facility of the present invention; Comprise rotating mechanism 1 and facility body 2; Described rotating mechanism 1 comprises outer shaft 11, interior axle 12, compressing mechanism 13 and the cutter 14 of hollow, and said outer shaft 11 is connected with the power take-off of facility body, and circumferentially is furnished with installing hole; Axle 12 is for being fixed on the camshaft on the described outer shaft 11 inner axis in described; Said compressing mechanism 13 runs through and is installed in the described installing hole; Described cutter 14 is fixed on the tail end of described compressing mechanism 13 through pin;
Described compressing mechanism 13 comprises that sleeve 131, tail end are provided with the push rod 132 of connecting hole 1321, are socketed in the spring 133 on the inner said push rod of said sleeve 131; Said sleeve 131 comprises cylindrical shell 1311 and the fixture 1312 that is positioned at the cylindrical shell bottom, and described push rod 132 is socketed in described sleeve 131 inside; Be provided with the groove 1322 of mounting cutter along the axis of said push rod 132.
Said push rod 132 length are greater than said sleeve 131 length.
Described compressing mechanism 13 is fixed on described fixture 1312 on the described outer shaft 11 through nut.
The length of outstanding said outer shaft 11 inwalls in described push rod 132 tops arrives the distance of said outer shaft 11 inwalls greater than the cam point of axle 12 in said.
When facility were started working, power outputed to outer shaft 11, and outer shaft 11 begins rotation; Because cutter 14 is fixedly connected on the outer shaft 11; Cutter 14 also follows suit and rotatablely moves, and in the rotary course, pushes between the flange of the top of compressing mechanism 13 and interior axle 12; Thereby the part of pressurized compression spring 133 drives cutter 14 and in the rotary tillage process, carries out stretching motion, and then forms vibrocutting.
Shown in Figure 1 the center cams axle of mechanism is fixed in order to vibrate rotary tillage mechanism, and cutter shaft rotates with angular velocity omega, and among the figure shown in the dotted line is that rotary blade moves to cam point position constantly.The speed that both direction is arranged in the cutter rotary tillage motion process: rotary speed v and the cam speed v that effect brings to constrictor
t,
v＝ωl
s(1)
l
sThe compressing mechanism top is not to the terminal length of cutter when compressing, and ω is the angular speed of cutter shaft rotation.
The rotary speed direction is vertical with tool orientation, so not vibration effect on the Y direction.The outline curve of cam has determined the characteristics of motion of push rod; Promptly determined the characteristics of motion of cutter; The characteristics of motion of cam follower has the polynomial motion and the trigonometric function characteristics of motion; This paper selects the sinusoidal acceleration characteristics of motion in the trigonometric function characteristics of motion, because this motion mode does not only have rigid shock but also do not have soft impulse in motion process.Cutter moves to the lift process that the B position is a push rod among the figure from the A position, and the equation of motion of lift S is:
H is the rise of cam in the formula, and δ is the corner of cam, δ
0Be the lift angle, ω is the angular speed of cutter shaft rotation, and a is the vibration acceleration of cam; Wherein, h=s
1-e, s
1Be the distance of interior axle center to the wheel rim top of cam, e is the base radius of cam, and θ arranges the angle that staggers for the adjacent columns rotary blade.
The characteristics of motion that from formula (2), can find out S is a sine curve; Because in the trigonometric function characteristics of motion; The principle of lift and backhaul is consistent, so the drawback movement of cam also is a sine curve, so cutter can produce sinusoidal vibration; And can adjust the amplitude of cutter through the rise that changes cam, adjust the frequency of vibration through the rotary speed ω that changes cutter shaft.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of protection scope of the present invention only limits to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
