As shown in Fig. 1~6, the present invention is equipped with cutter shaft component in spiral case 2, and cutter shaft component includes cutter shaft 16 and along cutter shaft
The both ends of the cutting blade 14 that 16 axially mounted multiple groups are put the first edge on a knife or a pair of scissors, cutter shaft 16 are mounted on spiral case 2 by bearing, installation in spiral case 2
There are multiple groups ledger-plate 12, and multiple groups cutting blade 14 and the axially staggered setting of multiple groups ledger-plate 12,12 end of ledger-plate of the invention
Portion is 1~10mm along the amount of coincidence of cutter shaft in the radial direction with 14 end of cutting blade.Multiple groups ledger-plate 12 is welded on by the present invention
On stationary knife tool apron 13, and stationary knife tool apron 13 is mounted on the opening of spiral case 2 by fastener, not only enables 12 installation side of ledger-plate
Just in spiral case 2, and it is also convenient for replacement ledger-plate 12, or safeguard to ledger-plate 12.Have on cutter shaft 16 of the invention
Multiple groups tool apron 15, along the circumferential direction equal part arranges multiple groups tool apron 15, and tool apron 15 of the present invention is L-shaped, and 15 side of tool apron is used for moving knife
Piece 14 connects, and the flanging on tool apron 15 can both increase the intensity of tool apron 15 towards the direction of rotation of cutter shaft 16, and rotate through
Cheng Zhong, cutting blade 14 and ledger-plate 12 shred stalk or weeds, are acted on by wind-force caused by the flanging and centrifugal force
Under, by after chopping stem or weeds uniformly shed.
As shown in Fig. 1~3,2 inside of spiral case of the invention is connect with hopper 5, and hopper 5 is with sieve plate 4, on the spiral case 2
Portion is equipped with feed hopper 2-1, has feeding mouth on feed hopper 2-1, the lower part of spiral case 2 is equipped with tilting passage 2-2, guide
The bottom of pipe 2-2 has discharge port, and the present invention is equipped with air inlet 2-3, and air inlet 2-3 and 4 lower part of sieve plate on the inside of spiral case 2
Hopper 5 communicate, in 16 high-speed rotation of cutter shaft, make to generate wind-force with the arc shaped blade 18 of the one of cutter shaft 16, and will be in hopper 5
Sundries sucking spiral case 2 in.
As shown in Fig. 1~4,3 two sides of auger on 16 top of cutter shaft of the present invention are mounted on bearing block 6 by bearing, the strand
Dragon 3 is existing feeding screw, and two bearings seat 6 is mountable on the rack or the bearing block 6 of side is mounted on the rack, is another
Side is mounted on spiral case 2, and stalk or weeds are sent to 2 top of spiral case by the blade on auger 3 and are equipped at feed hopper 2-1,
And the small powders such as seed then pass through the sieve plate 4 in hopper 5 that there are 5 lower parts of hopper.
As shown in Fig. 1~5,3 side of auger of the invention is pierced by hopper 5 and connect with clutch 7, and active force is made to pass through clutch
Device 7 passes to power on auger 3, therefore in active force cutting, the reverse of auger 3 and cutter shaft 16 can be prevented by clutch 7
It is rotated with inertia is continued, there is stable functional reliability.The other side of auger 3 of the present invention is pierced by spiral case 2 and connects with by driving wheel 1
