Abstract
The invention discloses a dual-shaft polisher with an adjustable shaft spacing, which can enable the working width to be adjusted. The dual-shaft polisher comprises a machine frame, wherein a driving wheel is connected to the machine frame in a rotary manner, the driving wheel rotates on a horizontal plane, and two sets of knife shafts are arranged on the machine frame; the knife shafts are connected to the machine frame through rockers, and the two rockers in the two sets of the knife shafts are symmetrically arranged; knife rests which can be used for mounting a grinding head are arranged under the knife shafts; the driving wheel is in transmission connection with the two knife shafts through torque, and an elastic cylinder is fixedly mounted on the machine frame, and a piston rod of the elastic cylinder is coaxial with a symmetrical shaft of the two sets of the knife shafts; the outer end of the piston rod is connected with a driving block which is hinged to the middle segments of the two rockets respectively through two connecting rods. The two knife shafts are symmetrically moved to adjust the shaft spacing, and the working width of the polisher can be changed.
Description
Technical field
The present invention relates to a kind of sander that can be used for rigid pavement.
Background technology
Sander is again small-sized pavement milling machine, is mainly used in: remove concrete, asphalt roads, epoxy resin, the exceeding position or carry out slight plucking to ground of abrasion-resistant ground; Removably finishing coat, paint, different kinds of roads graticule; When ground is impaired, contamination needs to renovate; Remove old terrace surface etc.
In recent years along with the development that domestic high ferro is built, the heavy ground milling machine tool of numerous domestic manufacturer production, most outfit many cutter shafts, working width obtains increase greatly, be applicable to the milling process on ground on a large scale, the cleaning of concrete road surface marker line, for hacking and the leveling on concrete surface, bridge floor, road surface, the coating cleaning that terrace is old.
Every root cutter shaft is provided with axially outward extending grinding head.Even if the length of grinding head has been greater than the spacing of diaxon on adjacent cutter shaft, by rational setting, grinding head interval is passed through between centers, and grinding head also can not be interfered mutually.Even if the spacing in fact between cutter shaft slightly adjusts, also can not affect the normal work of sander, but also the working width of sander can be increased, but current sander be difficult to usually adjustment cutter shaft spacing.
Summary of the invention
The invention is intended to the twin shaft sander providing a kind of distance between axles adjustable, to make its working width adjustable.
The twin shaft sander that distance between axles in this programme is adjustable, comprise frame, frame is rotated and is connected with driving wheel, driving wheel rotates in the horizontal plane, frame is provided with two groups of cutter shafts, cutter shaft is connected in frame by rocking bar, two rocking bars in two groups of cutter shafts are symmetrical arranged, the below of cutter shaft is provided with the knife rest can installing grinding head, driving wheel connects with two cutter shaft torque drive, frame is installed with telescopic cylinder, the piston rod of telescopic cylinder is coaxial with the axis of symmetry of two groups of cutter shafts, the outer end of piston rod is connected with drive block, drive block is hinged with the stage casing of two rocking bars respectively by two connecting rods.
Operationally, driving wheel continues drive two cutter shafts and rotates, and the blade holder turns of the rotating drive of cutter shaft on it, the grinding head that knife rest is installed can implement polishing work on work plane.If need the spacing of adjustment two cutter shaft, only need drive telescopic cylinder, telescopic cylinder makes the position of drive block change, and is shaken by connecting rod drive rocker, and two cutter shaft symmetries are mobile to reach distance between axles adjustment, can change the working width of sander.
Further, driving wheel is connected with two cutter shaft torque drive by belt.
Further, driving wheel is connected with two cutter shaft torque drive by sprocket wheel.
Further, two knife rests are for strip and be symmetrical arranged along institute's connection cutter shaft respectively, and the angle of two knife rests is greater than 70 ° and is less than 110 °.The angle of two knife rests is arranged can evade its risk of collision.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: driving wheel 1, rocking bar 2, cutter shaft 3, chain 4, knife rest 5, telescopic cylinder 6, piston rod 7, drive block 8, connecting rod 9.
Embodiment is substantially as shown in Figure 1: frame is rotated the driving wheel being connected with horizontal direction, frame is provided with two groups and erects the cutter shaft put, owing to being illustrated as top view, so can only see the cross section of cutter shaft.The lower end of cutter shaft is provided with the knife rest can installing grinding head, and two knife rests are for strip and be symmetrical arranged along institute's connection cutter shaft respectively, and the angle of two knife rests is roughly 90 °.Knife rest when two cutter shaft synchronous axial system on it can not interference and collision mutually.
Driving wheel is connected by sprocket wheel torque drive with two cutter shafts, and the width of driving wheel is comparatively large, can simultaneously around two chains.Rotate synchronously to drive two cutter shafts.
Cutter shaft is connected in frame by rocking bar, and rocking bar connects to ensure its rotational freedom with the journal bearing outer ring on cutter shaft.Two rocking bars in two groups of cutter shafts are symmetrical arranged, and the pin joint of two rocking bars in frame overlaps.
Frame is installed with telescopic cylinder, and the piston rod of telescopic cylinder is coaxial with the axis of symmetry of two groups of cutter shafts.The outer end of piston rod has been fixedly connected drive block, and drive block is hinged with the stage casing of two rocking bars respectively by two connecting rods.
Operationally, driving wheel continues drive two cutter shafts and rotates, and the blade holder turns of the rotating drive of cutter shaft on it, the grinding head that knife rest is installed can implement polishing work on work plane.If need the spacing of adjustment two cutter shaft, only need drive telescopic cylinder, telescopic cylinder makes the position of drive block change, and is shaken by connecting rod drive rocker, and two cutter shaft symmetries are mobile to reach distance between axles adjustment.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in manual etc. record the content that may be used for explaining claim.
