Abstract
The invention provides a blade for a bituminous pavement milling machine and a grooving machine. A tool bit is arranged at the front end of a cutter body; 45-degree chamfers are manufactured at the rear end of the root of the tool bit and on both sides of the front end face of the tool bit; the tool bit is that: an integrally connected sawtooth-shaped cutting edge is arranged in the radial direction of the front cutting face of the tool bit; and a cutting edge division groove is formed on the central line of the front cutting face of the tool bit. By using the blade, the cutting edge of the tool bit is very sharp, so the area of the cutting edge is increased and a cutting resistance is reduced; in the process of milling or grooving, even the tip of the first helical-form cutting edge at the head is damaged, the other helical-form cutting edges and straight-tooth cutting edges still have strong cutting forces; and the middle cutting edge division groove allows the cut-down bituminous concrete to be easily drained. The blade for the bituminous pavement milling machine and the grooving machine has a rational design and high working efficiency, can be used for milling and grooving, and can be used on the milling machine.
Description
Technical field
The invention belongs to the curing means in paving and equipment or the device technique field that the road surface of accomplishing is processed, be specifically related to build, repair, repair or demolish the curing means in paving of the auxiliary equipment in road or similar paving.
Background technology
China's asphalt roads growth rate is very fast, and the whole nation has formed the speedway network, because vehicle flowrate increases fast, and serious overload, asphalt roads is after use after a while, and the damage that the road surface will be in various degree need partly or entirely be keeped in repair it.The main disease of asphalt roads is rut, hole groove, gathers around bag, check crack, the rut of flexible pavement appearance, cheats groove, gathers around bag, has influence on the comfort level of road speed and traffic safety and driving; The crack appears in flexible pavement, carries out maintenance and handles as untimely, and rainwater is ceaselessly invaded infiltration; Sinkage can appear in the asphalt roads ground, and the asphalt roads supporting capacity is more and more lower, makes that pit appears in flexible pavement, disease such as subside; Influenced traffic safety; Maintain in early days in crack to flexible pavement, the crack of flexible pavement is in time filled up, to having very important significance the application life that prolongs asphalt roads.Way commonly used in the maintenance process of flexible pavement is that the bag of gathering around of flexible pavement is planished with milling machine; Groove is left with groover in rut, hole groove, crack; In groove, fill out the black top compound, pour into potting compound behind the crack fluting to flexible pavement, the local disease of flexible pavement is keeped in repair.
The milling machine that in the maintenance processes of flexible pavement, uses at present has two kinds; A kind of is large-scale milling machine; The primary structure of this milling machine is that milling and planing drum is installed on automobile chassis, and the diameter of milling and planing drum has 1m, and 6 circle milling cutter heads are installed on the external surface of milling and planing drum; Milling and planing drum is rotated by fluid motor-driven, and the lifting of milling and planing drum and decline are handled by hydraulic jack.This milling machine, complex structure is suitable on large-area flexible pavement, carrying out the milling operation, and the milling operation of gathering around bag, rut, hole groove that inapplicable asphalt road surface local occurs is also uneconomical.For this reason, the someone has designed small-sized asphalt road plane milling machine, this milling machine maneuverability, and the milling operation is carried out in the milling of gathering around hired car rut, hole groove that is suitable for the asphalt road surface local appearance.The situation of the groover that in the maintenance processes of flexible pavement, uses and the situation of milling machine are roughly the same, and large-scale groover and small-sized groover are arranged.
The milling that above-mentioned small-sized milling machine and small-sized groover use is identical with the blade of fluting, and the primary structure of blade is that the front end at cutter hub welds and is connected with the straight knife head, and the major defect of this blade is that the blade of straight knife head is not sharp; Have only a point of a knife, when carrying out milling with the fluting operation, point of a knife is easily damaged; Resistance is very big; The consumed power of motor is very big, has wasted fuel, has reduced the application life of motor.Carrying out milling and fluting during operation in addition, be not easy to be cleared, also needing manual work to clear up, wasting manpower, prolonging construction period, increasing operating expenses by milling and the old asphalt mixture that digs out.
Summary of the invention
Technical problem to be solved by this invention is to overcome the shortcoming that the blade of above-mentioned milling machine and groover exists, provide a kind of reasonable in design, operating efficiency is high, can carry out milling and the asphalt road plane milling machine of fluting operation and the blade of groover.
Solving the problems of the technologies described above the technical scheme that is adopted is: the front end at cutter hub is provided with cutter head; The root rear end of cutter head and cutter head front end face both sides are processed with 45 ° chamfering; Described cutter head is: the preceding cutting face arranged radially at cutter head has the zigzag cutting blade that is connected as a single entity, and the center line in the preceding cutting face of cutter head is processed with intermediate section sword groove.
Zigzag cutting blade of the present invention is: the cutting blade that is arranged in the cutter head root is a rip profile of tooth cutting blade; Be connected as a single entity with rip profile of tooth cutting blade and have 1 helical teeth shape cutting blade at least; The cutting angle of straight-tooth shape cutting blade is 90 °, and the cutting angle of helical teeth shape cutting blade is 70 °～80 °.Intermediate section sword groove of the present invention is a V-shaped groove, and the angle of intermediate section sword groove two sides is 28 °, and the angle of bottom land and cutter head outer face is 93 °～97 °.
The cutting angle of helical teeth shape cutting blade of the present invention is 75 °.The bottom land of intermediate section sword groove of the present invention and the angle of cutter head outer face are 95 °.
The preceding cutting face arranged radially that the present invention is employed at cutter head has the zigzag cutting blade that is connected as a single entity; The center line in the preceding cutting face of cutter head is processed with intermediate section sword groove, this blade, and the cutting edge of cutter head is very sharp; Increased the area of cutting edge; Resistance when having reduced cutting is in carrying out milling or slot grooving operation process, in case after the point of a knife of first helical teeth shape cutting blade of head is damaged; Remaining helical teeth shape cutting blade and straight-tooth shape cutting blade have very strong cutting force equally, and intermediate section sword groove makes that being cut the old asphalt concrete material that gets off is easy to discharge.That the present invention has is reasonable in design, operating efficiency is high, can carry out milling and fluting operation, can on milling machine, use.
