Backgauge rolling plate, described chopping cutter shaft one end is provided with for the sprocket wheel that is connected with power, and described backgauge rolling plate side wall is provided with many
Combined the ledger-plate matching with many set moving knife respectively.
Further, often cover dise knife disk and the bearing that described moving knife combination includes all being sleeved on chopping cutter shaft, and two
Group is symmetricly set on the cutting blade group on dise knife disk centered on the dise knife disk center of circle, and described dise knife disk passes through bolt and bearing phase
Even, described bearing and chopping cutter shaft welding, the cutting blade group on adjacent dise knife disk is in interlaced arrangement；Cutting blade group bag described in every group
Include the cutting blade that two panels is symmetricly set on dise knife disk both sides.
Further, the other end of described chopping cutter shaft is provided with nose circle disk, sets between described nose circle disk and adjacent dise knife disk
There are some support bars just to discharge gate, every described support bar is all equidistantly provided with some discharge bars, Ruo Gangen
Described support bar is circumferentially evenly arranged centered on shredding cutter shaft.
Further, it is lined with cushion block between every described cutting blade and dise knife disk.
Compared with prior art, the invention has the advantages that
1st, original grain threshing device in assembly of the invention and threshing room of combine is changed, will
The threshing that device is arranged on united reaper is indoor so that it may using united reaper harvesting and shred grazing Brassica napus and, this
Replacing with grain threshing device alternately, and then can achieve that corn combining operation is made with grazing Brassica napus straw chopping
Industry is alternately.Because this device is reasonable in design, structure is simple, and therefore, it is very convenient that this device not only dismantles assembling, and
Processing and fabricating cost is low, also can improve the utilization rate of united reaper.
2nd, grazing Brassica napus stalk is after entering assembly of the invention, and the cutting blade of high-speed rotation cooperation ledger-plate is by feeding oil
Dish straw chopping, the grazing Brassica napus stalk after chopping is discharged from threshing chamber discharge gate through the discharge bar being distributed on support bar,
The cutting to grazing Brassica napus, conveying and pulverizing can disposably be completed, not only can achieve the machine of the harvesting of grazing Brassica napus stalk and chopping
Tool is turned into industry, and can substantially reduce the labor intensity of artificial harvest operation.

Dise knife disk 3a is connected with bearing 3b by bolt, and bearing 3c is welded and fixed with chopping cutter shaft 2, the spacing between adjacent dise knife disk 3a
For 120～160mm (preferably 140mm), cutting blade group 3c on adjacent dise knife disk 3a is in interlaced arrangement, makes all cutting blade groups
3c arranges in Double helix as shown in Figure 4 on chopping cutter shaft 2, so that the outside helical feed of grazing Brassica napus stalk that will shred.
Every group of cutting blade group 3c includes the cutting blade 3c1 that two panels is symmetricly set on dise knife disk 3a both sides, in order to increase two panels cutting blade 3c1
Between spacing, be lined with cushion block 3d between every cutting blade 3c1 and dise knife disk 3a, the size of cushion block 3d is 50 × 30 ×
20mm.Additionally, ledger-plate 6 is identical with the quantity of dise knife disk 3a counting, that is, each dise knife disk 3a is correspondingly arranged on a stationary knife
Piece 6 so that in Double helix distribution cutting blade 3c1 match with the ledger-plate 6 being arranged on the wall 4a of side cut-out grazing Brassica napus stem
Stalk.
Again as shown in Figure 1 and Figure 2, chopping cutter shaft 2 the other end be provided with nose circle disk 7, nose circle disk 7 and adjacent dise knife disk 3a it
Between be provided with some support bars 8 just to discharge gate 1b, the two ends of every support bar 8 respectively seam in nose circle disk 7 and adjacent circle
On cutterhead 3a, and some discharge bars 9 are equidistantly provided with every support bar 8.Support bar 8 and discharge bar in the present embodiment
9 are both preferably three, and due to being limited by discharge gate 1b width, the spacing between discharge bar 9 is for 110～130mm (preferably
120mm).
During installation, the two ends of chopping cutter shaft 2 are fixed in main shaft bearing 1d, adjustment covers the backgauge rolling on screen cloth 1a
Plate 4 to all sieve apertures being completely covered by screen cloth 1a, to prevent material from spilling from the sieve aperture of screen cloth 1a.Departed from room by changing
Grain threshing device can achieve corn combining operation and grazing Brassica napus straw chopping operation replace replacing.
The power of grazing Brassica napus stalk chopper of the present invention passes through Chain conveyer by the engine spindle of united reaper, leads to
Cross sprocket wheel 5 and drive chopping cutter shaft 2, dise knife disk 3a and cutting blade 3c1 high-speed rotation successively, grazing Brassica napus stalk passes through charging aperture 1c
After entering threshing chamber 1, the cutting blade 3c1 of high-speed rotation cooperation ledger-plate 6 is by grazing Brassica napus straw chopping, the feeding oil after chopping
Dish stalk is discharged from discharge gate 1b through being distributed on discharge bar 9 on support bar 8, and transhipment materials vehicle will be discharged from discharge gate 1b
Broken stalk collects transhipment, feeds or the raw material as ensilage for fresh.
