Background technique
Two-wheel flute milling machine has construction efficiency height, periphery disturbance as one of state-of-the-art equipment of construction of diaphragm wall
Small, the advantages that grooving is high-quality, using more and more extensive in infrastructure construction.Its Construction Principle be using mud off,
Equipment milling wheel rotates milling and is crushed rock-soil layer, and rock slag and slurry mixture band upper ground surface are passed through muddy water point by dreg removing system
It is filtered from system, remaining mud recirculation return slot section achievees the purpose that milling slot.Milling wheel carries crushing hard ground
Layer, and stir, convey the task of rock slag that milling is got off to slag notch.
According to certain spacing distance, there are milling blind areas in milling wheel width direction for existing two-wheel flute milling machine, convenient for peace
Cleaning shoe on slag suction mouth passes through.Centre setting blind area milling wheel ground adaptability it is poor, encountered in milling process brittleness compared with
The rock stratum of difference easily forms dike at blind area, wears mill teeth and toothholder plate, or even holds up milling wheel and cannot continue climb milling;It encounters
Sticky layer, soil due to that cannot cut off in time at blind area, big clod easy to form;Simultaneously as the presence of blind area, milling wheel stir
It mixes and takes that slag ability is poor, big clod is deposited in slot bottom and cannot be discharged outside slot by slag suction mouth in time, and bottom clod is cumulative, slot
Bottom medium is layered, and thin mud is difficult to lower infiltration, and milling wheel continues the evaporation that fever in milling process further causes moisture, milling wheel
Periphery mud soil's water content is smaller and smaller, and worse and worse, hardness is higher and higher for mobility, the soil under the effect of milling wheel rotary squeezing
Milling wheel is wrapped up, paste wheel is formed, causes groove milling construction that cannot continue, needs to lift carriage arbor and manually rooted out to ground
Clod seriously affects construction efficiency, while carriage arbor frequently proposes to influence slurry trench stability in deep trouth construction, brings safety wind
Danger.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
It should be noted that in the description of the present invention, term "front", "rear", "left", "right", "upper", "lower", "inner",
The orientation or positional relationship of the instructions such as "outside" is to be merely for convenience of description originally based on orientation or positional relationship shown in the drawings
It invents rather than requires the present invention that must be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.
Term "front", "rear" used in present invention description, "left", "right", "upper", "lower" refer to the direction in attached drawing, term
"inner", "outside" refer respectively to the direction towards or away from geometric center of specific component.
As shown in Figs. 1-2, a kind of milling wheel, including wheel hub 1 and multiple mill teeth components, each mill teeth component helically the distribution of line shape
In on 1 outer circumference surface of wheel hub, mill teeth component includes toothholder plate 2 and the mill teeth 3 on toothholder plate 2, as shown in figure 4, adjacent milling
Tooth laps one another in projection of the wheel hub 1 on excircle expansion direction.
As shown in Fig. 2, direction of the one layer toothholder plate 2 farthest apart from milling wheel Milling Centre face 9 to separate Milling Centre face 9
Be obliquely installed, realize protection to 1 outer rim of wheel hub and milling wheel end cap, remaining toothholder plate with 1 outer circumference surface of wheel hub is perpendicular sets
It sets, realizes that stress is optimal, the abrasion of mill teeth 3 Yu toothholder plate 2 can be reduced.The one layer of tooth of Milling Centre face 9 farthest apart from milling wheel
The angle of the angle of inclination beta of seat board 2 is 3-5 °, realizes that stress is optimal while protecting milling wheel, when angle of inclination beta is greater than 5 °, toothholder
The comprehensive stress of plate 2 sharply increases, and the degree of wear is big.
As shown in figure 3, by the wheel hub 1 for two milling wheels arranged side by side for being located at 8 two sides of carriage arbor median plane along outer circle circumferential direction exhibition
