In another embodiment, the acute angle is 60 degree.It was verified that the first mounting surface 9 and second is cut
The angle of face 10 is that 60 may be implemented to reduce the load of 40% single cutting blade.
Another aspect of the present invention additionally provides a kind of cutter head structure using above-mentioned L like shape moving knife pressing plate.
In a specific embodiment, the cutter head structure includes plate shaped moving knife pressing plate 4, moving knife 5, tool apron weldering
Close 6 and above-mentioned any L like shape moving knife pressing plate 8；The moving knife 5 is uniformly mounted at circle distribution in tool apron soldering 6,
Several L like shape moving knife pressing plates 8 and plate shaped moving knife pressing plate 4 are installed on the moving knife 5, the L like shape moving knife pressure
Plate 8 is evenly distributed between the plate shaped moving knife pressing plate 4.
In another embodiment, all plate shaped moving knife pressures are replaced using the L like shape moving knife pressing plate 8
Plate 4.
In another embodiment, with bolt 7 by the L like shape moving knife pressing plate 8 and plate shaped moving knife pressure
Plate 4 is installed on the moving knife 5.
In another embodiment, the cutter head structure further includes chopper axis 1, belt wheel assembly 2 and bearing
Seat 3；The chopper axis 1 is installed in tool apron soldering 6, and is supported in 1 both ends bearing block 3 of chopper axis；It is described
Belt wheel assembly 2 be mounted on chopper axis 1 on, be used in combination fastener to fix.
In another embodiment, the fastener is screw and nut.
The technical scheme is that because the structure increase moving knife blade of the prior art is more difficult, in order to realize existing
It has ready conditions the lower quantity for increasing moving knife blade, improvement of the invention is：
Referring to Fig. 2~3：First, 12 moving knife 5 are equably mounted in tool apron soldering 6 at circle distribution, take 4 L like shape
Moving knife pressing plate 8 is equably attached to 5 on piece of moving knife at circle distribution, as installs a piece of L like shape moving knife pressing plate every 3 moving knife 5
8.Plate shaped moving knife pressing plate 4 is installed on remaining 8 moving knife 5, blending bolt 7 is by three's fixation.
Then, chopper axis 1 is installed in tool apron soldering 2, and is supported in 1 both ends bearing block 3 of chopper axis
Come.Finally, belt wheel assembly 2 is installed on chopper axis 1, fastener is used in combination to fix.
The most crucial part of technical scheme of the present invention is exactly the design of L like shape moving knife pressing plate 8 and uses.L like shape moving knife pressure
Plate 8 is just analogous to the moving knife pressing plate (Fig. 4~5) of L shape.The pressing plate is divided into the two sides A, B, and (i.e., the first mounting surface and second is cut
Face), and the two sides A, B has a certain degree (acute angle), when assembly L like shape moving knife pressing plate 8 is with moving knife 5, it is necessary to assure the faces A with
Moving knife 5 is in contact.There is one section of arc surface in the faces A middle section, and mounting hole is dispersed on arc surface, can ensure that L like shape is dynamic in this way
The arc surface in the faces A of knife pressing plate 8 has certain gap with the contact surface of moving knife 5, is connected with L like shape moving knife pressing plate and moves
When knife, L like shape moving knife pressing plate 8 has certain elasticity, and cutting blade fixation can be made more to fasten.The faces B are divided into the sides C, the sides D, the wherein sides C
Higher, and the sides D are relatively low, the sides C are close to belt wheel assembly 2 when installation.Wherein the sides the C connection sides C and the sides D upper surface are arc surfaces.It should
Arc surface is that the Its Track Design of moving knife when being rotated according to cutterhead comes out, because the movement locus of moving knife is a circumference, so
The face is designed to arc surface according to circumference profile, can both ensure the fortune of 8 second cut surface and moving knife of L like shape moving knife pressing plate in this way
Dynamic rail mark is identical, it is also ensured that 8 second cut surface of L like shape moving knife pressing plate during movement with the gap uniformity of stationary knife.
(see Fig. 3).
When work, belt wheel assembly 2 drives chopper axis 1 to rotate, and chopper axis 1 drives tool apron soldering 2 with certain rotating speed
Circular motion also moves in a circle therewith mounted on 2 moving knife 5 of tool apron soldering, L like shape moving knife pressing plate 8.At this point, L like shape moving knife pressure
The faces A of plate 8 are contacted with moving knife 5, and are fixed together, and the faces B of L like shape moving knife pressing plate 8 and moving knife 5 are at an acute angle；L like shape is dynamic
When knife pressing plate 8 circles, the movement locus in the faces B is almost identical as the movement locus of moving knife 5, and crop passes through L like shape moving knife
When between the faces B of pressing plate 8 and stationary knife, it is chopped into the effect of stationary knife relative motion by the faces B of L like shape moving knife pressing plate 8.
So L like shape moving knife pressing plate 8 has played moving knife at this time, moving knife can be used as.This also solves to increase in the prior art and move
The problem of knife difficulty.
Compared to the prior art, original 12 plate shaped pressing plates wherein 4 are changed to class L by technical scheme of the present invention
Shape moving knife pressing plate, and be equably installed on moving knife at circle distribution.When work, the faces L like shape moving knife pressing plate B circumferentially move,
And movement locus is overlapped with the movement locus of moving knife, can be used as moving knife use.Thus it is equal to the quantity for increasing moving knife,
The load for reducing single cutting blade improves cutting quality, while also enhancing the ability of throwing.
Technical scheme of the present invention can be advanced optimized, and according to the difference of crop, it is dynamic can to increase and decrease L like shape on cutterhead
The quantity of knife pressing plate.Moreover, to increase the intensity of L like shape moving knife pressing plate, die mould can be increased in L like shape moving knife pressing plate dogleg section
Processing.
The above is merely a preferred embodiment of the present invention, and the scope of protection of the invention is not limited thereto, any to be familiar with
The people of the technology disclosed herein in the range of be appreciated that that expects transforms or replaces, should all cover the present invention include
Within the scope of, therefore, protection scope of the present invention should be subject to the scope of protection of the claims.
