The sleeve of described active connection 4 for matching with cradling piece 3, for monomer or be welded into the cross of intersection, active connection 4 is provided with pin-and-hole or screw, is used for the location.
In the described first soil deflector 1 and the second soil deflector 2, the deflector of bending tilts and is welded with the native sheet of covering of arc, deflector becomes the mirror image symmetry with covering to be welded with on the native sheet between active connection 4, the first soil deflectors 1 and the second soil deflector 2.The processing of such structure is very convenient, and can so that about exchange install to realize different functions, for example realize the function of ridging or ridging.
In Figure 10, described furrow plough 5 has the both wings of expansion, and the tip that it is used to break ground and the bottom surface of both wings are positioned at same horizontal plane.
Be provided with screw-nut body in the described support regulating wheel 8, be used to install the back and regulate the height that supports regulating wheel 8.
The body formed plate 6 in described ridge is provided with the multiple row slotted hole.
As among Fig. 1 to Fig. 3, a kind of tobacco leaf ridging, intertillage and ridging integrated device comprise mini-size tillage machine 13, and ridging, intertillage and ridging device are installed on the mini-size tillage machine 13 by power traction connector 7;
In described ridging, intertillage and the ridging device, cradling piece 3 is mounted to cross by active connection 4, horizontal cradling piece 3 two ends or the first soil deflector 1 and the second soil deflector 2 are installed and/or support regulating wheel 8 by active connection 4;
On the first soil deflector 1 and the second soil deflector 2 or the body formed plate 6 in ridge is installed;
Vertical cradling piece 3 one ends or be equipped with by active connection 4 and support regulating wheel 8 and furrow plough 5;
Vertical cradling piece 3 one ends are equipped with power traction connector 7;
By rotary blade main shaft 11 crawling wheel 9 is installed on the power transmission shaft of mini-size tillage machine 13 both sides and/or broadcasts native blade 12 and/or little cultivated break bar 10.
A kind of method of operating of using said apparatus may further comprise the steps:
1) when intertillage is (after tobacco leaf transplants, prosperous long-term until tobacco leaf before and after the tobacco leaf League class, according to soil physico-chemical property and weeds in field situation, repeatedly carry out), furrow plough 5 is installed on the cradling piece 3 by active connection 4, cradling piece 3 one ends are installed and are supported regulating wheel 8, and the other end is connected with mini-size tillage machine 13 by power traction connector 7, and little cultivated break bar 10 is installed on the power transmission shaft of mini-size tillage machine 13 both sides; In Fig. 3, can install horizontal cradling piece 3 this moment.The little cultivated break bar 10 in the place ahead is smashed soil, in Figure 10, because furrow plough 5 has both wings broad, that launch, the tip that it is used to break ground and the bottom surface of both wings are positioned at same horizontal plane, be provided with screw-nut body in the support regulating wheel 8, be used to install the back and regulate the height that supports regulating wheel 8 thereafter.Thereby can regulate and control the degree of depth of intertillage, lower requirement operating personnel's qualification.When intertillage, the bottom of the ditch of leaving is plane rather than " V " font, can remove most weeds between the vega ridge, and soil between loose ridge reaches the intertillage effect.
When the vega trench digging before tobacco leaf is transplanted applies fertilizer, according to the method for operating 1 of device), ditch at vega, fertilizer is tiled in bottom of trench, the distribution of fertilizer is shattered into a plane like this, the stretching, extension of the plant root thereon that helps growing.
2) (before tobacco leaf is transplanted) during ridging, in Fig. 1, cradling piece 3 is mounted to cross by active connection 4, the first soil deflector 1 and the second soil deflector 2 are installed in horizontal cradling piece 3 two ends by active connection 4, this moment, the native sheet of covering of arc all was positioned at the inboard, horizontal cradling piece 3 two ends also are equipped with supports regulating wheel 8, regulate the height that supports regulating wheel 8 and can regulate the height of ridge body, the body formed plate 6 in ridge links to each other with the second soil deflector 2 with the first soil deflector 1 by bolt, which is provided with the multiple row slotted hole, thereby can regulate the width between the first soil deflector 1 and the second soil deflector 2, also can regulate the height of the body formed plate 6 in ridge
In Figure 11, Figure 12, on the power transmission shaft of mini-size tillage machine 13 both sides, crawling wheel 9 is installed, is broadcast native blade 12 and little cultivated break bar 10 by rotary blade main shaft 11, broadcast the inclination that native blade 12 has similar screw, this moment broadcast 12 operations of native blade after, soil is moved to the centre, so that enough soil is provided for the formation of ridge body, tentatively bring together by deflector then, cover native sheet preliminarily forming on it, finally be shaped by the body formed plate 6 in ridge at last, in use the setting height(from bottom) of the body formed plate 6 in general ridge is a little less than the height of covering native sheet.
During 3) ridging (certain intertillage of tobacco leaf ridging operation and vega operation simultaneously), cradling piece 3 is mounted to cross by active connection 4, with step 2) in the first soil deflector 1 and the exchange of the second soil deflector about 2 install, owing to reuse through the first soil deflector 1 and about 2 exchanges of the second soil deflector of optimal design herein, thereby saved cost.
Can see by Fig. 2, Fig. 8 and Fig. 9, this moment, the native sheet of covering of arc all was positioned at the outside, vertical cradling piece 3 one ends are equipped with by active connection 4 and support regulating wheel 8, and the other end is equipped with furrow plough 5 and power traction connector 7, is connected with mini-size tillage machine 13 by power traction connector 7;
On the power transmission shaft of mini-size tillage machine 13 both sides, crawling wheel 9 is installed by rotary blade main shaft 11, broadcast native blade 12 and little cultivated break bar 10, with step 2) in native blade about 12 exchanges of broadcasting install, so that this moment broadcast 12 operations of native blade after, soil is moved to both sides, because when intertillage and ridging, soil comparatively hardens, by little cultivated break bar 10 soil is smashed, by broadcasting native blade 12 soil is moved to both sides, crawling wheel 9 is avoided skidding when advancing, soil is pushed deflector under the both wings effect that furrow plough 5 launches, roll up the ridge body of ditch both sides again under the deflector effect, smears shaping by covering native sheet then.
By above-mentioned steps, make mini-size tillage machine 13 have the function of ridging, intertillage and ridging at lower cost.
By the furrow plough that furrow plough 5 is replaced by " V " shape, promptly its tip that is used to break ground is lower than the horizontal plane that both wings are positioned at, and its irrigation canals and ditches of leaving are " V " shape, thereby device of the present invention also has the function of trench digging.
