30 and driven wheel 40, chain 20 is set in the outside of driving wheel 30 and driven wheel 40 and connects with driving wheel 30 and the transmission of driven wheel 40
It connects, driving wheel 30 is rotatably provided in 10 rear end of rack, and driven wheel 40 is rotatably provided in 10 front end of rack, the periphery of chain 20
Multiple main gear pieces 21 are distributed with, the rotation direction of main gear piece 21 towards chain 20 tilts the first predetermined angular, 40 two sides of driven wheel point
Not She You accessory whorl 50, accessory whorl 50 and driven wheel 40 are coaxially connected, and the peripheral distribution of accessory whorl 50 has multiple secondary gear pieces 51, secondary gear piece 51
Rotation direction towards accessory whorl 50 tilts the second predetermined angular.
40 two sides of driven wheel of the present embodiment are since with accessory whorl 50, driven wheel 40 is able to drive 50 turns of accessory whorl when rotating
It is dynamic, so that the secondary gear piece 51 on accessory whorl 50 is able to carry out milling and dig operation, so that width is dug in the milling for increasing milling digging head.
When work, chain 20 as shown in Figure 1 rotationally clockwise, in rotation process, the continuous cutter of main gear piece 21
The earth material in the front of frame 10, since main gear piece 21 tilts toward the clockwise direction, main gear piece 21 earth material can be dug after cutting to
The lower section of rack 10 simultaneously takes earth material out of backward, meanwhile, accessory whorl wheel 50 rotates under the drive of driven wheel 40, and secondary gear piece 51 is also continuous
The earth material for cutting front, since secondary gear piece 51 tilts toward the clockwise direction, secondary gear piece 51 earth material can be dug after cutting to
Lower section.After secondary gear piece 51 hollows out the earth material in front, the soil body of two sides can collapse, main gear piece 21 exists due to not supporting to centre
When the earth material to collapse is dug in milling, the resistance being subject to is smaller, and therefore, milling is dug efficiency and increased.Since main gear piece 21 and secondary gear piece 51 are piece
Shape, it is easier to cut the soil body, also there is stronger cutting force for the rock stratum of larger hardness.
The driving mechanism (not shown) that driving wheel 30 can be driven to rotate is also provided in rack 10, driving mechanism is for example
For oil cylinder, certainly, head is dug in milling can not have driving mechanism, and driving force can be input from the outside.
