Description
Technical field
The utility model relates to cutter, is specifically related to a kind of gang tool.
Background technology
Blade type rotary head is the main working parts ensureing that annular cutting type excavator normally works, and its service behaviour determines the main performance index of excavator.The material of blade, shape, processing method, arrangement on the rotary shaft, number produce vital impact to the lower pick power of annular cutting type nursery stock excavator, operating efficiency.Current blade is single, affects the lower pick power of excavator, inefficiency.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides the gang tool that a kind of structure is simple, reasonable in design, easy to use, and blade adopts combined type, ensures the lower pick power of annular cutting type excavator, increases work efficiency.
In order to solve the problem existing for background technology, the technical solution adopted in the utility model is: it comprises excavation blade, gap between screw, cutting tip, helical blade, muck haulage helical blade, casting blade, rotary main shaft; Excavation blade is arranged on rotary head top, and excavation blade is welded on helical blade and rotary main shaft, and helical blade is welded on rotary main shaft, and excavation Partial Height is 5 ~ 10cm; Cutting tip is fixed (welding or with holding screw) at the external margin of helical blade, position on the lower side in the middle part of cutting tip is arranged on; Casting blade is arranged on rotary head top, and casting blade is welded on the sleeve of rotary main shaft, and do not rotate with rotary main shaft, and casting blade is arranged to 15 ~ 90 °, muck haulage helical blade is arranged on rotary main shaft periphery; There is gap between screw between the helical blade at each cutter place, be separated from each other, have the gap of general 1 ~ 5mm, each composite blade requires different to the material of helical blade, but helical blade is multistage is combined to form global shape, cut position enlarged in thickness, be convenient to cutting tip and install and radial motion.Cutting tip layering, become the putting of 15 ~ 90 ° of angles, overall in trapezoidal shape, cutting tip is telescopic, controls radial expansion distance within the scope of 1 ~ 5cm, the trench digging broadband required by applicable different tree-walk by hydraulic means; Excavation blade is telescopic, and cutter comes downwards to blade expandable when descending most, and distance of stretch out and draw back can reach 10 ~ 15cm, and cutting edge is arranged to certain cutting angle (15 ~ 80 °), realizes excavating bottom native ball; Rotary main shaft selects hollow shaft, and can install hydraulic oil pipeline, outer setting becomes notch cuttype, and according to each working position stressing conditions, diameter is different.
After adopting said structure, the utility model beneficial effect is: its blade adopts combined type, ensures the lower pick power of annular cutting type excavator, increases work efficiency, and structure is simple, easy to use.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutting tip cutting edge structure schematic diagram.
Description of reference numerals: rotary main shaft 1, casting blade 2, muck haulage helical blade 3, helical blade 4, cutting tip 5, gap between screw 6, excavation blade 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-Figure 2, this embodiment adopts following technical scheme: it comprises rotary main shaft 1, casting blade 2, muck haulage helical blade 3, helical blade 4, cutting tip 5, gap between screw 6, excavation blade 7; Helical blade 4 is welded on rotary main shaft 1, and excavation blade 7 and cutting tip 5 are arranged in radial slot that helical blade 4 is offered, angledly puts, as shown in Figure 2.Excavation blade 7 excavates Partial Height at about 8cm, and distance of stretch out and draw back can reach 10 ~ 15cm.Both can excavate downwards, again can transverse-longitudinal cutting; Cutting tip 5 is telescopic, radial expansion distance is controlled within the scope of 1 ~ 5cm by hydraulic means, trench digging broadband required by applicable different tree-walk, blade shape as shown in Figure 2, realize cutting and scraping to soil, the height of setting cutting tip 5 omits annular cutting soil to meet nothing on vertical direction, overall one-tenth razor shape.Cutting tip 5 is arranged on position on the lower side, middle part, is convenient to cut coring; Casting blade 2 is arranged on rotary head top, casting blade 2 is welded on the sleeve of rotary main shaft 1, do not rotate with rotary main shaft 1, muck haulage helical blade 3 is arranged on rotary main shaft 1 periphery, make soil transport to upper end from lower end by muck haulage helical blade 3, the casting blade 2 being arranged to certain angle is convenient to soil and is discharged to both sides; Gap between screw 6 is had between the helical blade 4 at each cutter place, be separated from each other, there is the gap of general 3mm, be convenient to the separate machined of helical blade 4, combine, each composite blade requires different to the material of helical blade 4, but helical blade 4 is combined to form global shape for multistage, cut position enlarged in thickness, be convenient to cutting tip and install and radial motion.
The blade of this embodiment adopts combined type, ensures the lower pick power of annular cutting type excavator, increases work efficiency, and structure is simple, easy to use.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
