In order to realize that the two scraping plates 2 can synchronously move back to back or opposite to each other, each vertical plate 1 is provided with two horizontal through grooves 7, pin shafts on the front side and the back side of each scraping plate 2 respectively penetrate through the corresponding side through grooves 7 and can move left and right in the through grooves 7, the left end and the right end of each vertical plate 1 are respectively fixed with a motor, the two motors can synchronously rotate, an incomplete gear 8 is fixed on an output shaft of each motor, a horizontal front-back direction rotating shaft is fixed on the inner side of each incomplete gear 8, a first gear 9 capable of being meshed with the corresponding side incomplete gear 8 is fixed on each rotating shaft, the front end and the back end of each rotating shaft respectively extend out of the corresponding side vertical plate 1 and are fixed with a winding wheel 10, each winding wheel 10 is wound and fixed with a rope 11, the inner side of each winding wheel 10 is provided with a guide block 12, the free end of each rope 11 penetrates through the guide block 12 and, each rope 11 is sleeved with a pressure spring 13, one end of the pressure spring is fixed on the guide block 12, and the other end of the pressure spring is rotatably connected to the corresponding side pin shaft.
In order that the circular rings 4 cannot rotate when moving left and right, a horizontal rail groove 14 is arranged below each circular ring 4, a vertical rod 15 is slidably mounted in each rail groove 14, and the upper end of each vertical rod 15 is fixed on the outer circular surface of the corresponding circular ring 4.
In order to realize better contact between the electric push rods 6 and the circular rings 4, two extending ends of each electric push rod 6 are respectively fixed with an arc-shaped supporting plate 16 with an outward opening, and the arc-shaped supporting plate 16 is an inner arc surface which can be attached to the outer circular surface of the corresponding circular ring 4.
In order to realize the movement of the device, a plurality of rotating wheels 17 are arranged on the outer side of each vertical plate 1, and the left and right movement of the device is realized through the rotating wheels 17.
The specific working process of the invention is as follows: this device opens two electric putter 6 when using for two electric putter 6 are pushed out to the outside, and this makes two scraper blades 2 apart from the increase, opens pawl 5 through the manual work and makes ratchet 3 not being retrained, rotates two scraper blades 2 to the level form, and first scraper blade 2 is the biggest with scraper blade 2 off-the-ground distance this moment, promotes this device through the manual work and moves to the lime powder top of piling, makes the lime powder pile arrange two scraper blades 2 in under the position.
The height of the lower ends of the scrapers 2 is adjusted according to the height of the lime powder pile, the ratchet 3 can be rotated by the adjustment mode of opening the pawl 5 to be bound, the lower ends of the two scrapers 2 are rotated to enable the lower ends to be contacted with the upper surface of the lime powder pile, after the lower ends of the two scrapers 2 are contacted with the upper surface of the lime powder pile, the two scrapers 2 inevitably present an inclined state with lower inner ends and higher outer ends, the pawl 5 is reset to enable the pawl 5 to be bound with the ratchet 3 and adjust the two electric push rods 6 to enable the lower ends of the two scrapers 2 to be contacted with each other, the vertical plate 1 is adjusted left and right to ensure that the joint position of the two scrapers 2 is the middle position of the lime powder, at the moment, the two motors are opened to synchronously rotate, the incomplete gear 8 is driven to rotate in the rotating, the winding wheel 10 rotates to tighten the rope 11, so that the two scrapers 2 move backwards, the lower ends of the pawls 5 cannot rotate inwards under the constraint action of the pawls 5 of the ratchet wheels 3, therefore, the lower ends of the scrapers 2 have the tendency of scraping lime powder to disperse outwards along the length direction of the vertical plate 1, the compression springs 13 are compressed in the process and have the tendency of rebounding and elastic potential energy, when the gears move to a toothless part to correspond to the first gear 9, the first gear 9 loses power to reset the two scrapers 2 towards the middle under the resetting action of the compression springs 13, at the moment, the lime powder at the height is scraped outwards, when the scrapers 2 reset towards the middle, the lower ends cannot be blocked, the scrapers 2 cannot rotate reversely due to the blockage of the lime powder, when the scrapers 2 move leftwards and rightwards, the electric push rods 6 on the two sides start to continuously and slowly retract inwards under the electrifying action, so when the scrapers 2 move for, the extension distance of electric putter 6 reduces, make the interval reduce between two scraper blades 2, there is the lower extreme of two scraper blades 2 to contact all the time this moment, consequently at the in-process that the interval reduces between two scraper blades 2, the upper end of two scraper blades 2 can progressively rotate to the centre, this process ratchet 3 pawl 5 can not restrict this rotation, two scraper blades 2 upper end is rotated to the centre and is made its lower extreme outwards rotate, at this moment, the lower extreme of scraper blade 2 reduces, reverse reset after ratchet 3 pawl 5 mechanism restriction scraper blade 2 lower extreme reduces simultaneously, consequently when two scraper blades 2 reciprocating motion still can realize scraper blade 2 motion to the intermediate position at every turn, the lower extreme of scraper blade 2 can reciprocate again after a distance of downstream, make the outside dispersion with the lime powder layer-by-layer, make whole dispersion process more even and level.
The dispersion meeting of a heap of lime powder is accomplished, can carry out the dispersion of next heap of lime powder and spread the work of scattering with this device again propelling movement to next lime powder heap top through rotating scraper blade 2 to the level.
Compared with the traditional equipment, the device has the following advantages:
1. this device riser 1's length direction is road surface length direction promptly, carries out the layering according to road surface construction direction with a lime powder heap and scrapes scattered whole dispersion process that makes, and the power that scraper blade 2 received can not be very big for whole lime ash content is more even at dispersion process, and the workman need not closely contact lime powder when high-efficient and save the cost can realize spilling lime.
2. The continuous back of contracting of in-process telescopic link at two scraper blades 2 reciprocating motion, the distance between two scraper blades 2 round pin axles constantly reduces this moment, make its lower extreme be close to each other when because two scraper blades 2 contact, the distance shortens between two round pin axles under the unchangeable condition of round pin axle height, two scraper blades 2 must reverse downwards, the downstream of scraper blade 2 can be realized to this reversal process, thereby realize every period of motion of scraper blade 2, its lower extreme all can a distance of lapse, just so realize scraper blade 2 to lime powder's successive homodisperse, make the dispersion effect better.
3. This device realizes the even paving to the lime powder through reciprocating motion's scraper blade 2, paves the in-process staff and can effectively avoid the contact with the lime powder that flies upward, has reduced the occupational disease that the workman led to the fact because of inhaling the lime powder, the effectual operational environment who improves the workman.
The lime powder spreading and flattening device is novel in concept, ingenious in structure and high in practicability, and effectively solves the problem that occupational diseases of workers are easily damaged due to low efficiency in the existing small-project pavement lime powder spreading and flattening process.
