The specific embodiment

Consult Fig. 2, Fig. 3, Fig. 5 and shown in Figure 6, the utility model is a kind of combined type wood fragments device, comprising:

One pedestal 10 has a pair of articulated section 11, a drive division 12 and at least one cutter fixed part 13 at least;

One driving shaft 20 is to be driven and can be rotated by this drive division 12;

One combined type rotary cutter 30 is provided with at least:

A, several pieces tool rest disks 31, each tool rest disk 31 have a cutter diameter D1 and a cutterhead thickness T 1, and each tool rest disk 31 has at least one pair of locking recess 311 and several locating holes 312;

B, several rotary cuttves 32 are to be located on the corresponding tool rest disk 31; Each rotary cutter 32 has a blade 321, a shank 322 and a cutting knife fixed part 323 (as shown in Figure 4), this cutting knife fixed part 323 is in order to this shank 322 is fixed on the corresponding locking recess 311, again, the rotary cutter 32 on the adjacent tool rest disk 31 is the predetermined angle theta 1 that stagger each other;

C, several fixation kits 33 are in order to penetrate these several locating holes 312 adjacent tool rest disk 31 to be locked together;

One dead knife portion 40, it is a cutter fixed part 13 of being located at this pedestal 10, and to blade 321 that should several rotary cuttves 32.

Consult Fig. 4, these several locating holes 312 comprise several locating hole 312A with dimple and several locating hole 312B of not having dimple and are staggered and form; Whereby, penetrate the locating hole 312A with dimple of each tool rest disk 31, and lock the locating hole 312B of not having a dimple on adjacent another sheet tool rest disk 31 with retaining element 33; Being about to adjacent two tool rest disks, 31 lockings is integral.Utilize this mode, all (the 3rd tool rest disk 31 of first tool rest disk 31 second tool rest disk of locking 31, the second tool rest disks, 31 locking, the rest may be inferred) tool rest disk 31 lockings can be integral.

In addition, consult Fig. 4 and Fig. 7, this cutting knife fixed part 323 have one revolve lock set 323A, a crushing block 323B and revolves lockhole 323C; Utilize this to revolve lock set 323A and pass this crushing block 323B and lock this and revolve among the lockhole 323C, make this crushing block 323B closely oppress the shank 322 of this rotary cutter 32, and then with these rotary cutter 32 firm being fixed on this tool rest disk 31.

Wherein, the side of this crushing block 323B is inclined-plane (taper theta 2 is arranged), so can lock tighter and tighter.

Applied in any combination about the tool rest disk of this case has following three kinds at least:

1. can freely adjust tool length: each tool rest disk 31 all has cutterhead thickness T 1 (as shown in Figure 3), can allocate the quantity of this tool rest disk 31 according to actual needs, to control the length of this combined type rotary cutter 30, further changes its wood fragments work width W.

2. can freely adjust the rotary cutter corresponding angle: this rotary cutter 32 can utilize several locating holes 312 on this tool rest disk 31 according to the difference of actual cut demand, adjusts the corresponding angle of adjacent rotary cutter 32, to reach the optimized cutting effect.

3. the type of replaceable rotary cutter.According to different cutting situations, the rotary cutter 32 that replaceable shape or material are different is to reach required cutting effect.

In sum, advantage of the present utility model and effect reduce:

1, Zheng Ti process time and cost are low.Because whole combined type rotary cutter is to be mutually locked by adjacent tool rest disk to be fixed as one, single tool rest disk is the disk for thickness number centimeter, can come processing and manufacturing by general machining machine and tool, the processing of its locking recess also is quite simple, therefore, whole difficulty of processing is low, and process time and cost are also low.

2, the effect of rotary cutting is good.The weight of combined type rotary cutter of the present utility model is big, so the inertia height, the kinetic energy when rotating at a high speed is high, and in addition, the predetermined angular that staggers each other of the rotary cutter on this adjacent tool rest disk equals cutting and chip removal in turn, so cutting effect is good.

3, easy to repair.When a certain rotary cutter damages, can pull down replacing separately, very convenient, so, keep in repair very simple and easy.

4, applied range.Because the chopping effect of this case is splendid, except general timber, more can cut hard wood, for example: coconut, trunk, branch, wooden useless pallet, wood furniture etc. can be applicable to fields such as agricultural, environmental protection unit, industry, applied range.

But 5 elasticity are revised the pan feeding width of wood fragments.Because the wood fragments work width W of the combined type rotary cutter 30 of this case (is consulted Fig. 3, also can say it is the pan feeding width of wood fragments) be that quantity by tool rest disk 31 decides, therefore, if will produce relatively large combined type wood fragments device, as long as the length of lengthening pedestal 10 and driving shaft 20, simultaneously, the tool rest disk 31 of assembling a greater number gets final product (strengthening wood fragments work width W); Otherwise, also can simply be modified as the combined type wood fragments device of more small-sized (dwindling wood fragments work width W), therefore, but elasticity is revised the wood fragments work width W of combined type wood fragments device.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
