The specific working process of the invention is as follows: when the device is used, the lower end of the thimble 7 is contacted with the ground and plays a supporting role by adjusting the extension length of the thimble 7, the lower end surfaces of the first scraper blade 1 and the second scraper blade 2 are contacted with the ground and can rotate around the thimble 7 at the moment, the nursing agent is poured into the rectangular frame structure, the hand-held sleeve 9 moves downwards, the sleeve 9 moves downwards along the second vertical rod 8 in the process, the free ends of the two ropes 12 are fixed on the sleeve 9, the sleeve 9 moves downwards to enable the two ropes 12 to be elongated, the winding wheel 11 drives the second vertical rod 8 to rotate at the moment, meanwhile, the coil spring 13 stores the force, the rotation of the second vertical rod 8 realizes that the second vertical rod 8 and the first vertical rod 6 can not rotate relatively under the action of the one-way bearing, at the moment, the second vertical rod 8 and the first vertical rod 6 rotate synchronously, when the sleeve 9 moves downwards, the rotation of the second vertical rod 8 drives the first vertical rod 6 and the thimble 7 to rotate, the rotation of the first vertical rod 6 drives the scraping and brushing unit to rotate through the supporting frame 5, meanwhile, when the sleeve 9 moves downwards, the circular ring 16 is driven to move downwards, the circular ring 16 moves downwards to extrude the pressure spring 15 and drive the piston rod of the first air pressure cylinder 14 to move downwards in the initial stage, because the elastic strength of the pressure spring 15 is greater than that of the tension spring 19, the compression amount of the pressure spring 15 in the initial stage of extrusion is small, so that the piston rod in the first piston cylinder extrudes the gas in the first air pressure cylinder into the corresponding air pressure telescopic rod 4 through the air pipe, the air pressure telescopic rod 4 extends out and stretches the tension spring 19, in the process, the first scraper 1 and the second scraper 2 which are originally in the same plane state are gradually changed into a U-shaped state due to the extension of the air pressure telescopic rod 4, in the process, the originally square frame structure is gradually changed into a strip-shaped rectangular frame structure, when the gas in the first air pressure cylinder 14 is conveyed into the corresponding air pressure telescopic rod 4, at this time, because the piston rod of the second piston rod is of a telescopic rod structure, in the first half section of downward movement of the sleeve 9, the piston rod of the second pneumatic cylinder 18 contracts, the gas in the second pneumatic cylinder 18 does not supply gas into the corresponding pneumatic telescopic rod 4, when the piston in the first pneumatic cylinder 14 moves downward by the sleeve 9 and exceeds the position of the exhaust port of the gas pipe, the piston passes through the exhaust port of the gas pipe along with the continuous downward movement of the sleeve 9, the gas in the corresponding pneumatic telescopic rod 4 in the first pneumatic cylinder can be discharged to the outside, at this time, the pneumatic telescopic rod 4 corresponding to the first pneumatic cylinder 14 is reset under the action of the tension spring 19, in the process, the scraping and brushing unit in the U-shaped structure is reset into a flat plate shape, along with the continuous downward movement of the sleeve 9, the first piston rod continuously moves downward and gradually moves to the limit position, in the process, the compression spring 15 starts to be squeezed and contracts to give way, so that the sleeve 9 can continuously move downward, with the continuous downward movement of the sleeve 9, the piston rod in the second pneumatic cylinder 18 contracts to the limit position, at this time, the downward movement of the sleeve 9 enables the volume in the second pneumatic cylinder 18 to be extruded and conveyed into the corresponding pneumatic telescopic rod 4 through the air pipe, at this time, the scraping and brushing unit corresponding to the second pneumatic cylinder 18 is converted into a U-shaped plate structure from the original plate structure, and the rope 12 is continuously pulled in the downward movement process of the sleeve 9, so that the winding wheel 11 drives the second vertical rod 8 to rotate, and the first vertical rod 6 and the support frame 5 are driven under the action of the one-way bearing, so that the whole device rotates around the thimble 77.
When the sleeve 9 moves to the lowest end position, the sleeve 9 starts to move upwards in a reverse direction, the first vertical rod 6 keeps rotating under the action of inertia force, the sleeve 9 moves upwards, the winding wheel 11 rotates reversely under the action of the coil spring 13 and rewinds two ropes 12, the second vertical rod 8 and the first vertical rod 6 can rotate relatively under the action of the one-way bearing, therefore, the sleeve 9 does not hinder the continuous rotation of the first vertical rod 6 when moving upwards, the sleeve 9 moves upwards to drive the ring 16 to move upwards, in the process, the piston rod in the first pneumatic cylinder 14 and the piston rod in the second pneumatic cylinder 18 are both moved upwards and reset, wherein gas in the first pneumatic cylinder 14 needs to be supplemented with air from the outside due to dissipation, the effective reset can be realized when the piston rod in the first pneumatic cylinder 14 resets under the action of the one-way valve 17, and the normal reset can be realized when the piston rod in the second pneumatic cylinder 18 does not have gas in the reset condition, the piston rod in the second pneumatic cylinder 18 is composed of a telescopic rod, the piston rod in the second pneumatic cylinder 18 is reset by the stretching force of the telescopic rod after the telescopic rod is stretched to the extreme position, after the resetting is completed, the sleeve 9 can be moved downwards again, the device is driven to rotate repeatedly, two groups of opposite scraping and brushing units are enabled to change into a U-shaped plate structure, and therefore the problem that the curing agent is not paved uniformly due to the fact that the curing agent is scattered to corners under the effect of centrifugal force is solved.
Compared with the traditional equipment, the device has the following advantages:
1. thereby this device reciprocates through the handheld sleeve 9 of workman and drives the rotation that second montant 8 drove first montant 6 when using, makes the rectangle frame structure can keep lasting rotation in this in-process, and wherein one-way bearing resets for sleeve 9 provides the relation of connection for the rectangle frame structure can keep the continuous rotation of equidirectional under the effect of inertial force in the sleeve 9 reset process.
2. In the rotating process of the rectangular frame, two groups of the four groups of scraping units are opposite to each other to form a pair, the interval between the two pairs of scraping units is changed into a U-shaped plate shape from a plate shape, when the scraping units are both in a plate-shaped structure, the rectangular frame structure is square, when one pair of scraping units is in a U-shaped plate structure, the rectangular frame is in a long strip-shaped rectangular frame structure, the volume in the rectangular frame is changed in the process, the liquid level of the curing agent in the rectangular frame is changed, downward leakage of the curing agent is promoted, and meanwhile, the curing agent gathered near the wall of the rectangular frame is pushed to the middle position in the rotating process due to the alternate change of the two pairs of scraping units, so that the whole curing agent is kept in an evenly distributed state in the rectangular frame, the problem that the scraping effect of the peripheral curing agent is good and the middle difference is caused is avoided, and the curing agent is spread more evenly.
3. The first pneumatic cylinder 14 and the second pneumatic cylinder 18 are stressed in a sequence through the segmented extrusion design, the air supply of the corresponding pneumatic telescopic rod 4 can be alternately realized by the two groups of pneumatic cylinders in the process, the corresponding alternate deformation of the scraping and brushing units is realized, the motion state and the sequence of the whole device are more reasonable, and the deformation process of the whole rectangular frame is smoother.
