Suitable position controls each telescopic hydraulic cylinder C, and the traveling wheel group 7 of diamond dust spreader is made to be detached from ground, then by each telescopic hydraulic
Cylinder C support, it is not only more steady in this way, also enhance the resistance to capsizing of diamond dust spreader, avoid because telescopic arm 5 with spread
Material device 6 stretches out too long and causes to overturn.First feeding shaft rotates under the driving of hydraulic motor C, in the effect of helical blade
The lower diamond dust floor material by storage bin 4 is delivered to 4 discharge port of storage bin, so by the feeding inlet of transfer feed bin 9 into
Enter transfer feed bin 9, since 9 storehouse internal upper part of transfer feed bin is equipped with the second feeding shaft, under the action of the second feeding shaft, Buddha's warrior attendant sandy ground
Terrace material will not all be deposited in the feeding inlet of transfer feed bin 9, when piling height reaches the position of the second feeding shaft, diamond dust
Floor material will be conveyed by the direction of 9 other end of the second conveying axial direction transfer feed bin, when diamond dust terrace material in transfer feed bin 9
When material whole height reaches the position of scheduled limit plate, diamond dust floor material touches limit plate, and limit plate is pushed upwardly,
And then the limit switch above limit plate is touched, and then control the first feeding shaft and shut down with the second feeding shaft.Transfer material
After the completion of storehouse 9 charges, telescopic hydraulic cylinder B902 control separating bottom plate 901 is detached, and makes the diamond dust terrace material in transfer feed bin 9
Material is fallen into the hopper 601 of material-strewing device 6, and then telescopic hydraulic cylinder B controls separating bottom plate 901 and sets back, and completes spreading
The feeding process of device 6, this process ensure that the continuity of construction without shutting down.Spreading axis 609 in hopper 601 is hydraulic
It rotates under the driving of motor B, and then is shelled the diamond dust floor material in hopper 601 by the protrusion on 609 axle body of spreading axis
It falls, is sprinkling upon concrete surface, when construction can be by adjusting the revolving speed of hydraulic motor B, to adjust spreading amount.Spreading construction
When control telescopic arm 5 it is flexible, diamond dust floor material is just equably spread in concrete surface.After the completion of the spreading of current location,
Each telescopic hydraulic cylinder C is shunk, traveling wheel group 7 is made to land, this diamond dust spreader is moved to close position, and then to not spreading
The concrete surface of material continues spreading.Telescopic hydraulic cylinder A607 can control hanger relative to telescopic arm 5 in a certain range
The movement on left and right directions is inside done, this makes spreading operation more flexible, not only easily facilitates in spreading at corner location
Material operation, can also adjust spreading position, even if the frame of diamond dust spreader when each telescopic hydraulic cylinder C erects spreader or so
It is very inaccurate to play position, without re-moving, erecting, only need to control telescopic hydraulic cylinder A607 just can control adjustment spreading position
It sets.
Hydraulic motor A drives pivoting support rotation, and upper spider 1 is rotated on lower bearing bracket 2, so that
Material-strewing device 6 can carry out spreading work in all directions, do not need to adjust repeatedly, turn around, substantially reduce the operation of needs
Space, it is more flexible, practical in edge spreading.
It should be noted that since diamond dust floor material has certain self-locking performance, do not turn in spreading axis 609
When protrusion dynamic, on spreading axis 609 is without stirring, diamond dust floor material will not be from the gap of spreading axis 609 and blow tank
In leak out.
Compared when making diamond dust terrace with artificial spreading using this diamond dust spreader, it is more uniform, conveniently,
Fast, the phenomenon that footprint that artificial spreading generates is easy to cause peeling to crack is also avoided, construction quality is optimized, improves labor
Efficiency of movement.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
