Mechanism and there is wrapping phenomena, and the branch under making to cut down is swung to unanimously.
Twisting device mainly includes：About first twisting device 9, about the second twisting device 10 and left and right adjusting device
11.Referring to Fig. 6-9, each twisting device has identical agent structure, all includes stator 26 and moving plate 27 respectively, stator 26 and dynamic
Piece 27 has central shaft hole 28 and 29 respectively, by connecting screw rod 30 through the central shaft hole 28,29 of the two and by compressing spiral shell
Stator 26 and moving plate 27 are installed together by female 31.Stator 26 is angularly set by circle on the radial end face of central shaft hole 28
Even number hole 33 is equipped with, moving plate 27 is on the radial end face of central shaft hole 29 along the same diametric(al) through central shaft hole 29
Two holes 34 are vertically disposed with, in two holes 34 of moving plate 27, steel ball 32 is provided with.On two holes 34 of moving plate 27 and stator 26
Align in arbitrary two holes 33 to 28 center of circle of Jing central shaft holes so that steel ball 32 is located in the hole of stator 26 and moving plate 27 simultaneously.
Fixed pole 35 is connected with stator 26, lever 36 on moving plate 27, is connected with.The position of lever 36 can pass through the hole for adjusting moving plate 27
34 are adjusted with the aligned position in the hole 33 of stator 26.Twisting device can be made according to the disposing way of connecting screw rod 30
Lever 36 is adjusted in a different direction, and when the axial direction of connecting bolt 30 is horizontally disposed, then lever 36 is perpendicular
Rotation regulation is carried out in straight plane, namely altitude mixture control can be carried out；When the axial direction of connecting bolt 30 is vertically arranged,
Then lever 36 carries out rotation regulation in the horizontal plane, namely can carry out width adjusting.
On stator 26, the number in hole 33 can need be configured according to precision, illustrate in Fig. 8 for 12, it is adjacent per phase modulation
One hole, 36 direction of lever change 30 degree, little to change angle, need to only increase the number in hole 33 on stator 26.Steel is being installed
During pearl 32, butter can be spread on its surface, so that steel ball 32 can facilitate the positioning with the hole 34 of moving plate 27, and can be prevented
During regulation, steel ball 32 skids off the hole 34 of moving plate 27.Hole 33 on stator 26 generally is circular, and the hole on moving plate 27
34 can also can be ellipse for circle.When the hole 34 on moving plate 27 is circular, steel ball 32 can not be moved in dynamic, stator
Dynamic position, in work, the dynamic, direction of stator fixes consistent, then twisting device is in the adjustment directions without fine adjustment function；And work as
When hole 34 on moving plate 27 is oval, the immovable position in stator 26 of steel ball 32 but somewhat can be moved in moving plate 27
Dynamic position, in work, 27 direction of moving plate somewhat can change, then twisting device has fine adjustment function in the adjustment directions, oval
The minor axis in hole 34 is equal with the aperture on stator 26, and the major diameter of slotted eye 34 is depending on vernier angle, longer vernier angle
Bigger, shorter vernier angle is less.
It should be understood that above-mentioned steel ball adjusts arm twisting device to cannot only be applied to the machine of cutting down that cuts in the present invention, also may be used
Needed on the machine for adjust direction, height or width with being applied to other.
In the present invention, the connecting screw rod 30 of about the first twisting device 9 is horizontally disposed, about the first twisting device
9 fixed pole 35 is fixedly mounted in moving trolley frame 1, and the lever 36 of about the first twisting device 9 connects or extends (a bodily form
Into) there is pressure pin 8.Referring to Figure 10, the connecting screw rod 30 of about the second twisting device 10 is also horizontally disposed, left and right adjusting dress
Put 11 connecting screw rod 30 ' vertically to arrange.The lever 36 ' of left and right adjusting device 11 is connected with coupling piece 7, left and right adjusting
The fixed pole 35 ' of device 11 can be fastenedly connected by bolt 40 with the lever 36 of about the second twisting device 10, on second
The fixed pole 35 of lower adjusting means 10 is connected with pressure pin 8.In cutting in the machine of cutting down for the present invention, on about the first twisting device 9 and second
Hole 34 on the moving plate 27 of lower twisting device 10 is all circular, without the need for fine adjustment function, and on the moving plate 27 ' of left and right twisting device 11
Hole 34 be ellipse, with fine adjustment function, so as to cut cut down in real-time regulation two cut the distance cut down between cutterhead 13.
The steel ball for describing the present invention below adjusts arm twisting formula duplicate rows to cut the operation principle of the machine of cutting down.
Cutterhead 13 is cut down due to having left and right two to cut, the machine of cutting down that cuts of the present invention can be while enter to two row branch such as Ramulus Moris
Row cuts and cuts down.As described above, the present invention's cuts the machine of cutting down and can be obtained by reequiping to existing corn harvester or tiller.This
Planting repacking mainly includes installing the actuating device of the present invention additional, cuts and cut down device and twisting device etc..The present invention duplicate rows cut the machine of cutting down because
This can realize the effect of a tractor serves several purposes.Become to cut the machine of cutting down by installing additional or dismantling said apparatus or be reduced into corn harvester or
Tiller.
When needs regulation is cut cuts down the height of cutterhead 13, about the first twisting device 9 is first adjusted, according to height to be adjusted
The hole 34 for spending to determine the moving plate 27 of about the first twisting device 9 to be directed at the position in the hole 33 of stator 26, so that lever
36 drive pressure pins 8 rotate to an angle in perpendicular, and pressure pin 8 passes through about the second twisting device 10, left and right twisting device
11 and coupling piece 7 it is final drive to cut cut down cutterhead 13 and be raised and lowered in the height direction.But it is this to adjust due to adjusting
Amplitude is big, easily makes to cut and cuts down the inclination certain with horizontal plane generation of cutterhead 13, then by adjusting about the second twisting device 10
To overcome this problem, 10 amplitude of accommodation of about the second twisting device is little, can will cut and cut down cutterhead 13 and be adjusted to put down with horizontal plane
OK.This regulative mode of height and position twice is not only accurate and convenient, it can also be ensured that cuts and cuts down 13 holding level of cutterhead.
When needing regulation left and right two to cut width (distance) cut down between cutterhead 13, then by adjusting left and right twisting device
11 realizing.In addition, cut cut down two row branches when, due between the tree of left and right two distance because in plant or growth process, some are wrong
Position, make not point-blank, it is to the left to the right, if two are cut and cut down cutterhead 13 and can not finely tune at any time, have it is partially interior partially
Outer branch just cut cut down less than.In the present invention, this Real-time and Dynamic adjustment is led by the left and right twisting device 11 and V-arrangement of the present invention
It is achieved to fork 14.Detailed process is：The branch on corresponding line is met and gathered to V-arrangement guiding fork 14, if line space occurs
Change, then under the retroaction of branch, V-arrangement guiding fork 14 will drive the moving plate 27 ' of left and right twisting device 11 relative to fixed
The somewhat activity of piece 26 ', cuts down cutterhead 13 and also just moves left and right with branch so as to drive to cut, so as to by branch not point-blank
Can also cut and cut down.
As described above, the present invention's cuts the easy to operate machine of cutting down, simple structure and easy to manufacture.
It will be appreciated by those skilled in the art that direction term "front", "rear" herein, "left", "right", " level ", " perpendicular
Be directly " etc. for it is normal advance cut the machine of cutting down (being direct of travel on the left of Fig. 1) for.
