The working principle is as follows: when the device is used, firstly, the shell 1 is opened into a vegetable field, the worm 203 is driven to rotate through the synchronous motor 202, so that the worm wheel 204 is driven to rotate, the front electric cylinder 205 is driven to rotate, the knife shell 215 is aligned with vegetables, the belt pulley B208 is driven to rotate anticlockwise through the stepping motor 207, so that the lifting belt 209 is driven to lower the fixed thin rod 214, the telescopic thin rod 213 moves downwards, the probe 217 is driven to move downwards, the probe 217 detects the vegetable head, if the vegetable head does not accord with the chopping standard, the machine moves to the next vegetable to continue to detect, when the vegetable which accords with the standard is detected, the stepping motor 207 rotates reversely, the probe 217 moves upwards, the control knife bar 211 moves downwards, the kitchen knife 218 is opened, the vegetable is wrapped in the kitchen knife 218, the stepping motor 207 rotates anticlockwise, the lifting belt 209 is driven to pull the control knife bar 211 upwards, so that the kitchen knife 218 is contracted and moves upwards under the action of the inner inclined plane, pulling the vegetables into the knife housing 215;

next, the synchronous motor 202 is started to drive the worm 203 to rotate, and further drive the worm wheel 204 to rotate, and further drive the front electric cylinder 205 to rotate, so that the knife housing 215 moves to the upper side of the vegetable throwing hole 109, and vegetables are put into the vegetable throwing hole 109. The vegetables contact the action rod 312 to move downwards, so that the action rod 312 acts on a small inclined plane connected with the inside of the contraction rod 313, the inclined plane moves inwards, the contraction rod 313 is driven to move inwards, the fixation of the lower end of the umbrella support frame 308 is loosened, the lower end of the umbrella support frame 308 which is originally compressed and tightened is enabled to move downwards, the erected support plate 307 which is erected is enabled to contract inwards, meanwhile, the piston rod of the rear electric cylinder 305 moves downwards rapidly, the vegetables are wrapped by the net and also move downwards, the limited frame 306 is blocked by the inclined plane to roll on the conveyor belt 107, and the vegetables are conveyed by the conveyor belt 107 to move towards the rear end of the shell 1 and then fall into a vegetable frame which is placed at the tail part of the shell 1 in advance;

the piston rod of the rear electric cylinder 305 moves downwards to drive the vertical supporting plate 307 to move below the limiting frame 306, the sliding rail motor 302 is started to drive the screw rod 303 to rotate and further drive the sliding block 304 to move and further drive the rear electric cylinder 305 and the mechanism above the rear electric cylinder 305 to move, when the sliding block 304 moves to the position under the mesh taking hole 110, the piston rod of the rear electric cylinder 305 pushes the vertical supporting plate 307 to enter the mesh taking hole 110 to take a mesh, then the piston rod of the rear electric cylinder 305 moves downwards to drive the whole netting equipment to move downwards, after the sliding block moves to a certain position, the sliding rail motor 302 rotates reversely to move the vertical supporting plate 307 sleeved with the mesh to the position under the vegetable throwing hole 109, then the piston rod of the rear electric cylinder 305 moves upwards to push the vertical supporting plate 307 sleeved with the mesh into the vegetable throwing hole 109 to wait for netting of vegetables, and the operation of the vegetable netting is realized in a reciprocating manner.
