Then, the driving wheel 218 is rotated, so that the two driving wheels 219 are driven by the driving belt 220 to synchronously rotate, the two threaded cylinders 206 are driven to synchronously rotate, the pressing length of the screw rod 207 is primarily adjusted, the scraping plate 202 and the auxiliary plate 211 are in contact with the concrete surface, and the heights of the scraping plate 202 and the auxiliary plate 211 are primarily limited according to the standard elevation and the indication of the standard position plate 308 and the scale 309;
In the initial state, through the adjustment, the hanging plug 203 and the sliding plate 209 are in a balanced state under the action of air pressure at two sides, the air pressure at two sides counteracts the dead weight of the hanging box 201, the scraping plate 202, the sliding plate 209, the supporting rod 210 and the auxiliary plate 211, at the moment, the threaded rod 301 can be rotated again according to the actual construction condition, the pressing plate 302 is driven to rise, and the air pressure at the top of the hanging plug 203 and the air pressure at the bottom of the sliding plate 209 are subjected to secondary fine adjustment;
At this time, as the top air of the hanging plug 203 and the bottom air of the sliding plate 209 are pumped out, the air pressure supporting force borne by the top of the hanging plug 203 and the bottom of the sliding plate 209 correspondingly decreases, and correspondingly, concrete can be given to the corresponding supporting force of the scraping plate 202 and the auxiliary plate 211 to supplement the reduced air pressure supporting force of the top of the hanging plug 203 and the bottom of the sliding plate 209, namely, the pressure of the corresponding scraping plate 202 and the auxiliary plate 211 to the bottom concrete can be increased, and according to the situation, the pressure of the scraping plate 202 and the auxiliary plate 211 to the bottom concrete can be adjusted, wherein the pressure is the surface collecting pressure in the surface collecting process, and the size of the pressure is equal to the reduction value of the air pressure supporting force borne by the top of the hanging plug 203 and the bottom of the sliding plate 209;
Then, the driving rods 320 at two sides are respectively rotated to drive the driving plates 319 to slide in the adjusting cavity 318, air in the sliding boxes 315 is pumped into the adjusting cavity 318 through the bottom groove 321 or air in the adjusting cavity 318 is pressed into the sliding boxes 315 through the bottom groove 321, under the conduction of the communicating pipe 322, the air pressure in the two sliding boxes 315 at one side of the driving rods 320 can be synchronously regulated and controlled by rotating the corresponding driving rods 320, and according to actual needs, the air pressure at the bottoms of the pistons 316 at two sides can be regulated to change the tension of the connecting blocks 313 given by the plugs 317 at two sides;
Under the transmission of the strut 310, the cross beam 311 and the sliding rod 312, the pressure can be applied to the hanging box 201, the drag force on two sides of the hanging box 201 can be changed, the hanging box 201 can correspondingly deflect under the drag force on two sides, further, according to the indication of the standard plate 308 and the scale 309, the angle of the hanging box 201 can be adjusted by changing the drag force on two sides of the hanging box 201 so as to meet the requirements of different slopes in the concrete surface collecting process, and when no slope is required, the driving rods 320 on two sides can be rotated to carry out compensatory adjustment on the surface collecting pressure in the surface collecting process, the adjustable range of the surface collecting pressure is enlarged, and meanwhile, the adjusting precision of the surface collecting pressure is improved, and only the air pressure at the bottoms of the pistons 316 on two sides is ensured to be kept the same in the adjusting process;
After the adjustment work is finished, the device can be pulled by an external traction mechanism to carry out the surface collecting work of concrete, and in the surface collecting process, due to uncontrollability in the concrete flowing process, the situation that the concrete surface has concave-convex fluctuation inevitably occurs in the advancing process of the device pulled by the external traction mechanism, so that the device can correspondingly fluctuate in the advancing process;
For convenience of description, the traveling direction of the device is taken as the front side direction, when the front side is concave, the supporting force of the concrete received by the auxiliary plate 211 at the front side is reduced, the supporting force of the concrete received by the auxiliary plate 211 at the rear side is kept in a standard state, and then a pressure difference is formed at two sides of the telescopic frame 213, so that the telescopic frame 213 correspondingly deflects under the action of the pressure difference, the positions of the strip boxes 208 at two sides are adjusted until the stressed state of the sliding plates 209 at two sides returns to the balanced state again;
In this process, as the expansion bracket 213 deflects, it drives the screw 212 to rotate correspondingly, forcing the slide plug 215 to slide toward the expansion bracket 213 on one side of the main cavity 2151, under the guide of the pilot valve 225, the hydraulic fluid in the main cavity 2151 is pressed into the rotating cavity 2171 on the top through the top pipe 221 connected with the hydraulic fluid, and under the pressure, the hydraulic fluid then flows into the cavity between the expansion bracket 213 on one side and the slide plug 215 in the auxiliary cavity 2152 through the top pipe 221 on the other side under the guide of the pilot valve 225 on the other side;
in this process, as the hydraulic fluid flows into the rotating cavity 2171 at the top, the rotating wheel 217 at the top correspondingly rotates under the extrusion of the hydraulic fluid, so that the rotating shaft 216 drives the driving wheel 218 to synchronously rotate under the driving of the rotating wheel 217, and then the threaded cylinders 206 at two sides synchronously rotate under the driving of the driving belt 220, so as to reduce the extension length of the screw rod 207, raise the hanging box 201, reduce the pressing depth of the scraping plate 202, compensate the sinking depth of the device, and keep the scraping plate 202 at the elevation;
Conversely, if the front side is raised, the supporting force of the concrete received by the auxiliary plate 211 on the front side is lowered, the supporting force of the concrete received by the auxiliary plate 211 on the rear side is kept in a standard state, the telescopic frame 213 is reversely deflected under the action of the pressure difference, at the moment, the sliding plug 215 is reversely deflected under the driving of the screw 212, under the guiding of the pilot valve 225, the hydraulic fluid in the main cavity 2151 is pressed into the rotating cavity 2171 at the bottom through the bottom pipe 222, finally, the threaded cylinder 206 is reversely rotated under the driving of the rotating wheel 217 at the bottom, the pressing depth of the scraping plate 202 is increased, the sinking depth of the device is compensated, and the scraping plate 202 is kept at the elevation;
In the above process, during the sliding process of the sliding plug 215 towards the expansion bracket 213 at the main cavity 2151 side, under the flow guiding of the corresponding pilot valve 225, the sliding plug 215 in the auxiliary cavity 2152 will press the hydraulic fluid in the auxiliary cavity 2152 near the main cavity 2151 into the cavity near the auxiliary cavity 2152 in the main cavity 2151 through the outer through pipe 223, so as to supplement the hydraulic fluid in the main cavity 2151;
Conversely, during the sliding process of the sliding plug 215 towards the expansion bracket 213 on one side of the auxiliary cavity 2152, the sliding plug 215 inside the auxiliary cavity 2152 can press the hydraulic fluid inside the auxiliary cavity 2152 on the other side of the sliding plug 215 into the space inside the main cavity 2151 on the other side of the sliding plug 215 through the inner through pipe 224, and supplement the hydraulic fluid in the main cavity 2151, so as to ensure the stability and consistency of dynamic adjustment of the pressing depth of the scraper 202.
