Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of this utility model, rather than the enforcement of whole
Example.Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment for obtaining, belongs to the scope of this utility model protection.
This utility model provides a kind of cutter of the efficient splashproof with guide function, as depicted in figs. 1 and 2, bag
Vehicle frame and the topping machanism being set up on vehicle frame is included, the topping machanism includes cutter disc groups 1, protects 2 and of protective cover of the cutter disc groups 1
Drive the lead agency of 1 high-speed rotation of cutter disc groups.
Specifically, as shown in figure 3, the cutter disc groups include multiple cutterheads 11.Wherein, as shown in figure 4, arbitrary cutterhead 11 includes
Round cutterhead body 14 and multiple blades 15, multiple blades 15 are arranged at the periphery of cutterhead body 14,15 plate-like knot of blade
Structure, radially to dispose at an angle with cutterhead body 14, the bending direction of multiple blades 15 is consistent, multiple cutterheads 11 for blade 15
Cutterhead body 14 axle center be located at same rotary shaft 12 on, rotary shaft 12 by lead agency drive.For the ease of preparing, and
Improve the production efficiency of blade 15 and cutterhead body 14, it is preferred that the material of blade 15 is consistent with the material of cutterhead body 14, can
Select for intensity, hardness it is higher, the metal such as lower-cost material, such as steel, ferrum.
As shown in figure 3, the two ends of rotary shaft 12 are provided with fixed structure 13, pass through between rotary shaft 12 and fixed structure 13
Ball engagement, can be in rotation in fixed structure 13.It is during cutter disc groups 1 are subject to lead agency drive, each in cutter disc groups 1
Cutterhead 11 can be acted on Fructus Ananadis comosi plant simultaneously.When cutter disc groups 1 are rotated, the rotation of the end of each blade 15 according to cutterhead 11
Turn direction successively cutting, crush Fructus Ananadis comosi plant, it is tiny fragment, fiber that Fructus Ananadis comosi plant is crushed, and is conducive to Fructus Ananadis comosi plant
Fragment, fiber carries out also field and processes.
Preferably, in order to disposably thoroughly crush Fructus Ananadis comosi plant, in this utility model embodiment, lead agency is excellent
Select hydraulic motor.The output speed of hydraulic motor is 2500 revolution per seconds to 5000 revolution per seconds, wherein, with 3500 revolution per seconds to 4000
Revolution per second is more excellent.
Further, as shown in Figure 4 and Figure 5, in order that blade 15 is more easily crushed in Fructus Ananadis comosi plant, and in order to carry
High degree of grinding, the top of blade 15 may be configured as the axial direction bending to cutterhead body 14.
In this utility model embodiment, as shown in figure 4, adjacent blade 15 is arranged on the not coplanar of cutterhead body 14,
And top is respectively to contrary axial direction bending.Therefore, when cutter disc groups 1 are rotated, each blade on each cutterhead body to
Fructus Ananadis comosi plant applies active force, and blade of the top respectively to contrary axial direction bending can more uniformly, more thoroughly crush spinach
Trailing plants plant.
In order to extend the life-span of cutterhead 11, in this utility model embodiment, the number of the multiple blades 15 on cutterhead 11 is
Even number, the angle between the adjacent blade 15 of any two are consistent.Therefore, when rotary work, cutterhead 11 is overall for cutterhead 11
Uniform force, so that be conducive to extending the life-span of cutterhead 11.
Preferably, as shown in figure 4, the top of blade 15, the internal face for circumferentially bending are provided with for cutting Fructus Ananadis comosi plant
The blade face 16 of strain, and direction of rotation of the cutterhead 11 when working is in opposite direction with what blade 15 circumferentially bent, then each knife
Piece 15 can more easily cut Fructus Ananadis comosi plant, the power output needed for reducing rotating with movable knife disc 11.
Blade 15 can be fixedly installed on cutterhead body 14 in several ways, for example blade 15 by welding, or with
