The rotation directions of the externally tangent cutter head and the furling cutter head are opposite; the inner cutting edge of the furling cutter disc and the outer cutting edge of the outer cutting disc can intermittently complete approaching and shearing actions.
The counter-rotating double-disc shearing device has the following beneficial effects:
1. the furling cutterhead of the device can directly take branches to be cut into a shearing area in the rotating process without other auxiliary furling mechanisms;
2. the furling cutterhead and the externally tangent cutterhead of the device rotate oppositely, and the external cutting edge and the internal cutting edge cooperatively act to transversely cut the branches, so that the branches can be kept level at the fracture, and the branches can grow again;
3. the furling cutterhead of the device can furl branches to be cut and is matched with the externally tangent cutterhead to cut the branches, and the structure is simple and multiple-effect.
4. The working rotating speed of the furling cutter head and the circumscribed cutter head of the device is low, the energy consumption is low, and the shearing efficiency is high.

Detailed Description
A rotary double disk shearing apparatus according to the present invention will be described in detail with reference to the following examples.
As shown in fig. 1 and 2, a contra-rotating double-disc shearing device 1 comprises an outer cutter disc 3 and a gathering cutter disc 10; the rotating axis of the externally tangent cutter head 3 is superposed with the rotating axis of the furling cutter head 10; the externally tangent cutter head 3 is closely arranged on the furling cutter head 10.
The outer cutter disc 3 shown in fig. 2 comprises: a circumscribed main disc 5; a shaft barrel 4 fixedly arranged at the central position of the externally tangent main disc 5; arc-shaped outer edge cutters 6 arranged at intervals on the circumferential edge of the externally tangent main disc 5; and an outer cutting edge 12 arranged on the arc-shaped outer edge of the outer edge cutter 6.
The folding cutter head 10 shown in fig. 2 includes: the main disc 7 is folded; a main shaft 8 fixedly connected with the central position of the furling main disc 7; the furling cutters 9 are arranged at intervals at the circumferential edge of the furling main disc 7 and form a wedge-shaped groove with the furling main disc 7; and an inner cutting edge 11 arranged on the inner arc-shaped edge of the furling cutter 9.
As shown in fig. 3 and 4, the rotation directions of the circumscribed cutterhead 3 and the furling cutterhead 10 are opposite; the inner cutting edge 11 of the furling cutter head 10 and the outer cutting edge 12 of the outer cutter head 3 can intermittently complete extrusion shearing action.
The operation of a counter-rotating double-disc shearing apparatus according to the present invention will be described
1. Furling action of branch to be cut by furling cutter head
In the attached figure 3 (from top to bottom), when the device of the invention works, the furling cutter head 10 rotates clockwise, and the circumscribed cutter head 3 rotates anticlockwise. When the root of the furling cutter 9 is coincident with the root of the outer edge cutter 6, the branch 2 to be cut can be sleeved at the opening part of the wedge-shaped groove of the furling cutter 9, and the branch 2 to be cut enters the wedge-shaped groove area of the furling cutter 9 by further rotating the furling cutter head 10.
2. Cutting branches with furling cutterhead and externally tangent cutterhead
In fig. 4 (from top to bottom), when the device of the invention works, the furling cutter head 10 rotates clockwise, and the circumscribed cutter head 3 rotates counterclockwise. When the root of the furling cutter 9 and the root of the outer edge cutter 6 are gradually separated from the overlapped position, the outer cutting edge 12 of the outer edge cutter 6 approaches the branch 2 to be cut to the left side, and the inner cutting edge 11 of the furling cutter 9 approaches the branch 2 to be cut to the right side. The inner cutting edge 11 and the outer cutting edge 12 extrude and cut the branch 2 to be cut together, and then the branch 2 to be cut can be cut, so that the transverse cutting and stubble leveling of the branch can be realized.
