Since the cement pole is cylindrical, sagging is inevitable after spraying, resulting in uneven surface. Therefore, the feeding group 300 is provided to feed the material while smoothing the coating on the lower half of the pole to solve the above problem. Specifically, a material nozzle 101 and a feeding hole 102 are provided on the top of the feed box 100, a suction pump 130 is installed on the feeding hole 102, and a plurality of liquid dispensing tubes 120 are installed on the output end of the suction pump 130; the spraying group 200 includes a spraying tube 210 correspondingly sleeved with the lower ends of the plurality of liquid dispensing tubes 120 and a plurality of nozzles 220 embedded in the inner side of the annular spraying tube 210, and the nozzles 220 are prior art and will not be described in detail here; in addition, by setting the nozzles 220 on the plurality of spraying tubes 210 with gradually decreasing diameters, a multi-layer spraying is formed on the surface of the cement pole and the amount of spraying is gradually reduced, that is, the amount of spraying of the inner layer is large and can be adsorbed on the surface of the inner pole, and when the outer layer is sprayed, the rapid sagging of the coating is controlled due to the small amount; The top of the spray pipe 210 is disconnected and closed to allow the crane rope to pass smoothly; a through hole is opened in the middle of the bottom surface of the spray pipe 210 to be plugged into the liquid distribution tube 120, so that the coating is diverted from the middle of the bottom of the spray pipe 210 to both sides thereof, thereby ensuring that the spray volume of the nozzle 220 is uniform; a plurality of rollers 140 are embedded between the inner walls of the feeding platform 110, and a feeding motor 150 for driving the plurality of rollers 140 to rotate is installed on the side wall of one end of the feeding platform 110, and a synchronous movement is achieved by arranging a conveyor belt between both ends of the plurality of rollers 140, so that the cement poles placed on the feeding platform 110 are smoothly transported.

[0023] Furthermore, the liquid dispensing tube 120 is L-shaped and a liquid dispensing plate 121 is embedded in its lower port, which is used to separate the volume of the port of the liquid dispensing tube 120 to separate the sprayed coating; the feed end of the suction pump 130 is sleeved with a straight pipe plugged into the feeding hole 102 and the straight pipe extends to the top of the bottom of the feed box 100, and the upper ends of several liquid dispensing tubes 120 are sleeved with horizontal tubes and the tops of the horizontal tubes are plugged into the curved tube arranged at the output end of the suction pump 130.

[0024] Furthermore, a stinger 230 is welded between the plurality of spray pipes 210. The stinger 230 is annular and has an open top. The bottom of the stinger 230 is supported and fixedly connected to the bottom of the feed box 100 by a flat plate. A number of nozzles 220 are arranged in a ring with equal intervals. The outer diameter of the middle part of the roller 140 is smaller than the outer diameter of its two ends, and the central axis position of the roller 140 is higher than the nozzle 220 located at the bottom of the spray pipe 210. The inner diameter of the circle surrounded by the nozzles 220 is larger than the large diameter end of the cement pole, so that the cement pole on the roller 140 can smoothly penetrate the central axis of the spray pipe 210 for movement and be evenly sprayed.

[0025] Specifically, the feeding group 300 includes a pair of feeding frames 310, a plurality of feeding belts 320 sleeved between the pair of feeding frames 310, and a plurality of hanging groups 330 suspended side by side below the feeding belts 320; one end of the feeding frame 310 is aligned with the end of the spraying pipe 210 in the horizontal direction, and a row of a plurality of hanging groups 330 is coaxially arranged with the spraying pipe 210, so that the cement pole after spraying can smoothly pass through the hanging group 330 and be suspended; A feeding motor 311 is installed at one end of the feeding frame 310 for driving a plurality of feeding belts 320 to circulate, so as to transport the cement pole to the other end of the feeding frame 310 for unloading; the hanging group 330 includes an upper hanging member 331 and a lower hanging member 332 which are hinged and a plurality of spreading wheels 333 embedded in the inner wall of the lower hanging member 332; the upper hanging member 331 and the lower hanging member 332 form an open ring structure and the central axis thereof is coaxially arranged with the central axis of the spray pipe 210, that is, the cement pole is supported by the lower hanging member 332; at the same time, the plurality of spreading wheels 333 are in rolling contact with the lower half of the cement pole to spread the paint evenly and eliminate sagging.

[0026] Furthermore, a round shaft is sleeved between the two ends of a pair of conveying frames 310, and one end of the round shaft is coaxially connected to the conveying motor 311, and the conveying belt 320 is sleeved with the pair of round shafts. The conveying belt 320 is made of rubber and has stainless steel skin bonded to its upper and lower sides to increase its tensile strength; a number of hanging rods 321 are inserted and penetrated between the sides of the conveying belts 320 at equal intervals, so that the conveying belts 320 are connected and move as a whole, which increases the strength of the suspended cement pole and prevents the conveying belts 320 from falling sharply; The top of the upper hanging member 331 is provided with a collar 3311 which is tightly sleeved with the hanging rod 321; a spring-pressing sheet 334 is provided on the outer side of the hinged joint of the upper hanging member 331 and the lower hanging member 332, and the spring-pressing sheet 334 is an arc sheet and has the same central axis as the upper hanging member 331 and the lower hanging member 332; the spring-pressing sheet 334 is made of spring steel in the form of a sheet, so that it has elastic force and rebounds to reset the lower hanging member 332; since the gravity of the cement pole exerting pressure on the lower hanging member 332 is along the tangent direction of the hinged joint of the upper hanging member 331, and there is no lateral force, coupled with the rebound force of the spring-pressing sheet 334, the upper hanging member 331 will stably suspend the lower hanging member 332 to form a supporting state; When the hanging group 330 carries the cement pole and is transported to the discharge end of the conveyor frame 310 and turns, the upper hanging part 331 moves with the conveyor belt 320 through the bend, and the tangent direction of its hinge becomes horizontal. Therefore, the gravity of the cement pole presses down the lower hanging part 332 and the upper hanging part 331 to bend, so that the cement pole rolls out smoothly from the opening between the upper hanging part 331 and the lower hanging part 332, and then the lower hanging part 332 is reset under the action of the rebound force of the spring pressure sheet 334.

[0027] Furthermore, clamping blocks 3312 are provided on the outer walls of the upper hanging member 331 and the lower hanging member 332 and near the hinged end. The cross-sections of the two clamping blocks 3312 are L-shaped and symmetrically arranged. The upper and lower ends of the spring-pressing sheet 334 are snap-fitted with a pair of clamping blocks 3312, and a gap is left between the upper and lower ends to facilitate the bending and deformation of the spring-pressing sheet 334.

[0028] Furthermore, the smear wheel 333 is composed of a short shaft and a pair of rubber sleeves sleeved outside thereof, and the two ends of the rubber sleeve are in a round roller structure of one small and one large, so as to contact the cement pole with a large area for smearing; a ring sleeve 336 is sleeved in the middle of the short shaft of the smear wheel 333, and a ring block 335 is welded at the bottom of the ring sleeve 336 and arranged horizontally and vertically with the central axis; The lower hanging part 332 is in a semicircular ring structure and its inner arc surface is provided with a plurality of V-shaped positioning grooves 3321 at equal intervals, and both sides of the positioning groove 3321 are provided with conical avoidance grooves 3322; the ring block 335 is rotatably connected to the positioning groove 3321 by a pin, so that the ring block 335 can swing and automatically touch the cement pole; the end of the smearing wheel 333 is engaged with the avoidance groove 3322, so that the smearing wheel 333 is not interfered by the inner arc surface of the lower hanging part 332 when it swings.

[0029] In addition, in order to protect the coating on the surface of the cement pole and to stack and store it after drying, a drying group 400 is arranged below the discharge end of the feed rack 310. The drying group 400 includes a downwardly inclined collecting rack 410, a retaining wall 420 fixedly arranged at the lower end of the collecting rack 410, and supporting wheels 430 rollingly connected to the collecting rack 410; the supporting wheels 430 are sleeved and matched with the two ends of the cement pole; when the cement pole is transported to the intersection of the feed rack 310 and the collecting rack 410, the two supporting wheels 430 are inserted into the two ends of the cement pole until the cement pole rolls out of the lower hanging part 332 and falls onto the collecting rack 410, and a pair of supporting wheels 430 rolls along its inclined surface to the retaining wall 420 and stops to wait for drying, and then the cement pole is lifted away by a traveling crane and stored at a selected location.

[0030] Specifically, a guide rail 411 is embedded on the top surface of the material collecting rack 410 and along its inclined direction, and a wheel groove 431 for engaging and rolling with the guide rail 411 is opened in the middle of the supporting wheel 430, and the two side surfaces of the wheel groove 431 are in an outwardly inclined state so as to engage and roll with the guide rail 411, thereby ensuring that the cement pole is supported and rolled to the lower end of the material collecting rack 410; a sleeve shaft 432 matching the end hole of the cement pole is coaxially welded at one end of the supporting wheel 430, thereby ensuring that a pair of supporting wheels 430 coaxially support the cement pole and roll smoothly.

[0031] When the integrated equipment for preparing and spraying the environment-friendly anti-corrosion coating of the cement pole of the present invention is working, the raw materials of the anti-corrosion coating are injected into the feed box 100 for stirring and mixing, and then the cement pole is placed on the feed platform 110 for transportation. When the cement pole enters the stinger rack 230, the suction pump 130 is started to pump the anti-corrosion coating liquid in the feed box 100 into a plurality of spray pipes 210, and sprayed out through a plurality of nozzles 220, thereby forming a multi-layer spray coating layer on the surface of the cement pole; after the cement pole is transported to the bottom of one end of the feed rack 310, it is supported by a plurality of hanging groups 330, and a plurality of smearing wheels 333 roll in contact with the lower half of the cement pole to evenly spread the coating and eliminate sagging; At the same time, cement poles to be sprayed are continuously placed on the feeding platform 110, so that all the previously sprayed cement poles are pushed to the bottom of the feeding frame 310; at this time, the feeding motor 311 is started again to drive the plurality of feeding belts 320 to circulate, and the plurality of rows of hanging material groups 330 carry the sprayed cement poles to the discharge end of the feeding frame 310; When the cement pole is transported to the intersection of the feed rack 310 and the collecting rack 410, two supporting wheels 430 are inserted into the two ends of the cement pole until the cement pole rolls out of the lower hanging part 332 and falls onto the collecting rack 410. The pair of supporting wheels 430 rolls along the inclined surface to the retaining wall 420 and stops to wait for drying. Then the cement pole is lifted away by a crane and stored at a selected location.

[0032] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
