In the above-mentioned technical solutions, movable pulley is respectively mounted on the first bottom plate 1 and the second bottom plate 2, in order to be planted in sisal hemp
Tanaka moves, and the moving direction of the movable pulley on the first bottom plate 1 and the movable pulley on the second bottom plate 2 is consistent, the first bottom plate 1 and the
Two bottom plates 2 are connected by a flexible board 3 so that the first bottom plate 1 can pull the second bottom plate 2 to move when moving, the material of flexible board 3
Matter can be the high polymer material for having certain elasticity, such as the polyethylene of low-density, it is preferred that be flexible rubber.First column 11
It is separately fixed at the second column 21 on the first bottom plate 1 and the second bottom plate 2, the first column 11 and the second column 21 are scalable,
Can be that flexible rod member is realized by leading screw and nut mechanism or cylinder mechanism.First top plate 12 and the second top plate 22 are fixed respectively
In the upper end of the first column 11 and the second column 21, the raising and lowering of the first top plate 12, the first top plate 12 so can be achieved
With the extension side that the first guide rail 13 and the second guide rail 23, the first guide rail 13 and the second guide rail 23 are respectively arranged with the second top plate 22
To vertical with the moving direction of the first bottom plate 1 and the second bottom plate 2 respectively, so that the first sliding block 14 and the second sliding block 24 can be with
The side vertical with moving direction of the present invention moves up.First support bar 15 and second support bar 25 are rotatably arranged on respectively
On first sliding block 14 and the second sliding block 24, i.e., first support bar 15 and second support bar 25 are equivalent to a rotary shaft.In a word, divide
The first control stick 16 and the second control stick 26 that An Zhuan be in first support bar 15 and second support bar 25 can not only follow
First bottom plate 1 and the second bottom plate 2 are moved, and the first top plate 12 and the second top plate 22 can also be followed to lift, can also follow first
The sliding block 24 of sliding block 14 and second moves up perpendicular to the side of the first bottom plate 1 and the moving direction of the second bottom plate 2, can also follow
The support rotating of first support bar 15 and second.First circular shear blade 19 and the second circular shear blade 29 pass through the first mounting blocks 18 respectively
It is connected with the second mounting blocks 28 with the first control stick 16 and the second control stick 26, the first mounting blocks 18 and the second mounting blocks 28 pass through
4th elastic rod connects, and therefore, follows the first control stick 16 and the second control stick 26, the first circular shear blade 19 and the second circular knife
Piece 29 can move on the moving direction of the first bottom plate 1 and the second bottom plate 2 respectively, can also be respectively perpendicular to the first bottom plate
1 and second the side of bottom plate 2 move up, can also be respectively in the direction vertical with the first bottom plate 1 and the moving direction of the second bottom plate 2
Upper movement, it can also be rotated rotating around first support bar 15 and second support bar 25.So, the first bottom plate 1 is promoted in operator
After entering sisal hemp planting site with the second bottom plate 2, the first bottom plate 1 is preceding, and the second bottom plate 2 is rear, with the first circular shear blade 19 and the
Two circular shear blades 29 gather in sisal hemp, and the posture that operator is previously required to manually realize can be realized by machinery, pole
Big has liberated operator.
Manipulate two circular shear blades of interconnection respectively with two control sticks, on the one hand the cut coverage of sisal hemp is increased
Greatly, the harvesting efficiency of operator is improved, on the other hand two circular shear blades can have certain with vertical direction in the horizontal direction
Dislocation, it is highly effective when the height height of sisal hemp differs, or sisal hemp and the distance of the present invention are not fixed.Such as when adjacent
Two plants of sisal hemps from low to high when, you can will make the height of the second circular shear blade 29 lower with the second control stick 26, i.e., first is circular
The circular shear blade 29 of blade 19 and second is in inclined-plane, two plants of sisal hemps is disposably gathered in completion, and without at twice
Harvesting, therefore, can be in the interior circle of the first circular shear blade of regulation 19 and second in a big way using two circular shear blades are manipulated respectively
The cutting posture of shape blade 29, than the various growth postures that sisal hemp is suitable for one circular shear blade of a joystick manipulation.
The first bottom plate 1 and the second bottom plate 2 are connected with flexible board 3, the present invention can be avoided to a certain extent in field
High spot can not stop, and the present invention is had certain anti-seismic performance, therefore, the convenient rugged sisal hemp of the present invention
Plant field.
In order to protect circular shear blade, the present invention makes first using the first elastic rod 17, the second elastic rod and the 3rd elastic rod
The tilting section of control stick 16 is connected with the first mounting blocks 18, so, can when the first circular shear blade 19 is encountering the hard things such as stone
With retraction, it is unlikely to contact for a long time with stone and damages, in order to improve protecting effect, also makes the first mounting blocks 18 and the second peace
Fill connection of the block 28 by the 4th elastic rod.
In another technical solution, described sisal hemp harvesting device, first elastic rod 17, second elastic rod
Set with the 3rd elastic rod each parallel to horizontal plane, and first elastic rod 17, second elastic rod and described
