Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-3, the road surface bur automatic cleaner for smooth-riding surface, it includes chassis 1 and is fixed in bottom
Placement and vertical plane drive device 3 at an angle, the clutch end of the drive device on the roller 2 of disk surrounding, the chassis
Be connected with substantially L-shaped cutter by connector 4, the cutter include with the horizontal part 5 of connector horizontal transition and with ground
The extended line of the clutch end of the vertical vertical component effect 6 in face, the connector and drive device is at an angle, also solid on the chassis
The lifting screw 7 linked with drive device is connected to, the lifting screw screw top is combined with rotating disk 8.
Obviously, in the same direction, the driving force of drive device is while conduct for the direction of advance of the incline direction of drive device and complete machine
The power source of complete machine, α angles are acute angles, and it can be 30 °, 45 °, 60 ° etc., and connector can be steel or other rigid materials
Material is made, and the extended line of the clutch end of connector and drive device must be also α angles, so when drive device occurs back and forth
The inclined driving force of drive device can be converted to horizontal driving force by cutter during motion, and will not be to the past of drive device
Multiple motion produces obstruction；The horizontal part and vertical component effect of cutter can be integrally formed, and can also be segmented and are welded, horizontal part and hang down
Arc transition section is preferably provided between straight portion, is so more beneficial for eliminating internal stress.Drive device can be impact drill/electric hammer/
Electric pick etc. can provide the device of impulsive force output, such as in impact drill or the head installation connecting element of electric hammer, connect certainly
The transmission impulsive force that fitting must be rigid connector to stablize is to cutter.
Rotary turnplate controls drive device upper and lower displacement when using, and then controls the laminating degree on cutter and ground, tool
Body say be vertical component effect bottom and ground laminating degree, but can so have a problem that how to understand vertical component effect and ground
How the laminating degree in face knows the contact size on vertical component effect and ground in other words, in order to solve on the problem, connector
Pressure detection mechanism can be connected with, the pressure detection mechanism includes the straight tube 9 of distribution perpendicular to the ground, the straight tube bottom
It is connected with outside the roller bearing 10 parallel with vertical component effect bottom, the straight tube and is connected with by spring catch 11 under normality highly less than straight
The angle steel 12 of pipe, causes straight tube to can be movable relatively with angle steel when spring catch is pressurized.
Because roller bearing is parallel with vertical component effect bottom, therefore when vertical component effect moves downward close proximity to ground, roller bearing is also downward therewith
Close proximity to ground, the pressure that both are subject to is identical.And roller bearing can be by the pressure transmission being subject to straight tube, straight tube can give angle steel one
Individual active force causes angle steel to be moved downward relative to straight tube, i.e., relative to straight tube relative motion occurs for angle steel, at this moment straight tube and angle
Vertical displacement difference between steel can be observed clearly, for its degree of displacement of apparent display, to determine vertical component effect and ground
The contact in face, can have graduation mark in straight tube top indicator, the graduation mark when relative to straight tube relative motion occurs for angle steel
Gradually it will expose outside angle steel, so that pressure value be converted to the scale value of observable, so as to true according to different road surface materials
Fixed different pressure value.Because the vertical component effect pressure required for significantly different road surface material is different, such as marble road surface
The pressure needed is larger, and the pressure required for solid wooden floor board is smaller, it is necessary to observe scale value to determine that vertical component effect connects with ground
Whether tactile pressure is suitable.
Such as Chinese utility model patent application number CN201620003612.0 and Chinese utility model patent application number
Two kinds of chewing gum cleaning machines disclosed in CN201620348985.1 are all to chewing gum carry out level using brush or rubber bumper
Friction, the oxide layer that chewing gum shows during friction can be destroyed, and what is exposed has the inside meeting of viscosity and humidity
The adhesive region of diffusion is rubbed into, bonding separated but still in each other's thoughts expands pollution face on the ground, it is more difficult to remove.It is Chinese real
Cleared up when machine is operated and can not directly be seen by eyes with chewing gum disclosed in new patent application number CN201620086507.8
Chewing gum position is observed, the presence of chewing gum can only be sensed by pressure sensor, once the very thin thickness of chewing gum
When may can not detect the presence of chewing gum, cause follow-up hydrojet and strike off work and can not carry out, cleaning blade is over the ground
The pressure in face is uncontrollable, it is impossible to the patch ground pressure for clearing up blade is adjusted according to different road surface materials；It is fragrant additionally, due to mouth
The shape of sugar is often irregular, is to roll operation during the machine operation, it is impossible to ensure it is disposable by chewing gum from ground
Root out, it may be necessary to which repeatedly operation could remove chewing gum repeatedly, and operating efficiency is relatively low.
Find, perfectly drive device can be provided by test of many times when the height of vertical component effect is 1.8-2.2mm
Inclined driving force be converted to the horizontal actuator force of cutter Level Promoting and cutter pressed into subaerial vertical drive power, such as
The height of fruit vertical component effect it is too high for example more than 2.2mm when cutter can produce the bounce of vertical direction, if the height of vertical component effect is too
The torque of vertical direction is too short during low such as less than 1.8mm, the bad flexible modulation of vertical drive power, and easily ground or cutter are made
Into damage, the preferred embodiments of the present invention be vertical component effect height be 2mm, can provide best most stable of horizontal actuator force and
Vertical drive power, can save material again.
Find in use, though there is the High definition of vertical component effect, but when road conditions are bad, cutter still can produce vibration,
Vertical component effect can not abut in road surface and carry out horizontal movement, and the vertical drive power that it is subject to is non-constant, when being contacted with chewing gum such as
Fruit chewing gum shell is harder to upspring, in order to solve that the horizontal part with cutter can also be connected with the problem, connector
The preload piece 13 of contact, preload piece give cutter apply a pressure vertically downward so that vertical component effect all-the-time stable give ground
Apply the pressure of a reinforcement, the running orbit of cutter can not be changed when contacting with harder chewing gum disposably will
Chewing gum and surface separation.The preload piece can be various section bars, the reinforcement of such as welding, rigid connector etc., but excellent
Choosing is disk roller, because disk roller can provide a directed force to cutter, when cutter and harder chewing gum or other hard things
Matter will not cause other strength phenomenon to hinder the operation of drive device, but pass through roller when contacting to one reaction force of drive device
The rotation of wheel is dissolved, the operation for enabling drive device to stablize.
In order to strengthen cleaning effect, dust catcher 14 can be mounted with chassis at least side, or chassis both sides simultaneously
Dust catcher is mounted with, the dust catcher air outlet is connected to flexible pipe 15, and the end of the flexible pipe is placed exactly near vertical component effect, very moment is fragrant
Chewing gum is sucked and stored by sugar by cutter and surface separation rear dust collector by flexible pipe.
For the ease of operation, it can be mounted with chassis periphery and drive device and lifting screw are enclosed in interior framework
16, handrail 17 is connected with the framework.
The workflow of the present invention is as follows：Start drive device, promote complete machine to advance, while the vertical component effect of cutter is closely
Face, is moved along ground level, and when the vertical component effect of cutter is contacted with the chewing gum on ground, vertical component effect is by chewing gum and ground
Adhesion at directly chewing gum is rooted out, the original structure and state of chewing gum are not destroyed, will not ground residual chewing gum it is residual
Slag, rapidly and efficiently, stores while dust catcher sucks the chewing gum after rooting out by flexible pipe, continues next round operation.
When the machine is operated in hard ground such as marble floorings, regulation rotating disk causes vertical component effect and the ground of cutter
Contact is in default suitable scope, the graduation mark that exposes on observation straight tube, when reaching the rotating disk that stopped the rotation after predetermined value,
Start the machine and carry out operation.Equally when the machine is operated in softer ground such as solid wooden floor board, adjust and reveal on rotating disk, observation straight tube
The graduation mark gone out, when reaching the rotating disk that stopped the rotation after predetermined value, starts the machine and carries out operation.
The application field of the obvious present invention is more than that.Those skilled in the art are expected that it can be used for removing ground
On other burs, such as the ice cube remained on be crushed patch clod on the ground or road surface etc., chewing gum it is clear
Except a simply most representational application of the invention, and should not be regarded as the restriction to purposes of the present invention.Therefore it is of the invention
It can be used for removing the flexible adhesive thing such as chewing gum on smooth-riding surface, the rigidity that can be used for removing on smooth-riding surface is easy
Broken bur such as clod, the present invention is minimum to its structure destructiveness when for removing clod, will not road pavement cause two
Secondary pollution, and if removing clod using conventional meanses, clod can be changed into broken clod, the chip of clod can be scattered in road surface,
It is difficult to clear up.
