A plurality of arc-shaped chutes that match the oscillating protrusions 211 are provided below the carrier 209. The arc-shaped chutes cooperate with each other to form an oscillating boss. The intermittent cooperation between the oscillating protrusions 211 and the oscillating bosses intermittently lifts the carrier 209, allowing the carrier 209 to oscillate under the cooperation of the oscillating protrusions 211 and the arc-shaped chutes, thereby vibrating the cement within the precast cement part.

[0038] like Figures 6 and 7 As shown, the lower end of the linkage rod 208 is plugged with a drive shaft 212. The drive shaft 212 plays the role of plugging, limiting and rotating the linkage rod 208.

[0040] like Figures 4 and 5 As shown, the outer side of the driving shaft 212 is rotatably mounted with an assembly rack 214, which is fixedly connected to the bottom surface of the sliding workbench 201. The assembly rack 214 serves as an assembly limiter for the driving shaft 212.

[0041] like Figures 4 to 7 As shown, the lower end of the sliding table 201 is rotatably connected to a transmission shaft 215. The transmission shaft 215 transmits power to the drive motor 218. The transmission shaft 215 and the multiple sets of drive shafts 212 are aligned in a straight line. Synchronous pulleys 216 are fixedly connected to the outer sides of the transmission shaft 215 and the multiple sets of drive shafts 212. Synchronous belts 217 are sleeved between each of the multiple sets of synchronous pulleys 216. The cooperation between the synchronous pulleys 216 and the synchronous belts 217 synchronizes the drive shafts 212.

[0042] like Figures 4 and 5 As shown, the lower end of the transmission shaft 215 is fixedly connected to a drive motor 218. The transmission shaft 215 is rotationally driven by controlling the operation of the drive motor 218.

[0043] like Figures 9 and 10As shown, a pair of resonant smoothing mechanisms 3 are fixedly mounted above the processing box base 1. The resonant smoothing mechanisms 3 include a plurality of trowel plates 301, which are arranged on one side of the sliding workbench 201. The trowel plates 301 smooth the cement above the precast cement mold, thereby improving the casting surface quality of the precast cement part.

[0044] like Figures 9 and 10 As shown, a connecting pin 302 is fixedly connected to the top of each of the plurality of trowel plates 301, and the connecting pin 302 is rotatably connected to the frame 101. The trowel plates 301 are assembled and limited by the connecting pin 302. At the same time, the angle of the trowel plates 301 can be adjusted by rotating the trowel plates 301.

[0045] like Figures 9 and 10 As shown, the bottoms of the plurality of trowel plates 301 are hollow, and a resonance reed 303 is fixedly connected to the cavity of each of the trowel plates 301. By controlling the vibration of the resonance reed 303, the trowel plates 301 resonate, so that the trowel plates 301 can oscillate and smooth the top surface of the cement precast mold.

[0046] like Figures 2 to 3 As shown, a resonance drive unit is mounted on one side of each of the plurality of trowel plates 301. The resonance drive unit is used to resonately strike the trowel plates 301. The resonance drive unit includes a striking shaft 304. The striking shaft 304 secures and rotationally drives a sleeve 305. Multiple sets of evenly distributed sleeves 305 are fixedly connected to the outer sides of the striking shaft 304.

[0047] like Figures 9 and 10 As shown, the outer sides of the multiple sets of sleeves 305 are fixedly connected with multiple evenly distributed connecting members 306, and the ends of the multiple connecting members 306 are fixedly connected with knocking balls 307. The knocking balls 307 rotate with the rotation of the connecting members 306 to knock the trowel 301.

[0048] It is worth noting that the multiple connecting members 306 are made of flexible materials, which ensures the rotational operation reliability of the multiple groups of striking balls 307.

[0049] like Figures 2 to 3 As shown, one side of the plurality of knocking shafts 304 is fixedly connected with a linkage pulley 308, and a linkage belt 309 is sleeved between the plurality of linkage pulleys 308. The plurality of knocking shafts 304 are synchronously driven by the cooperation of the linkage pulley 308 and the linkage belt 309.

[0050] like Figures 2 to 3As shown, a driving gear 310 is fixedly connected to one side of the striking shaft 304, and a rack 311 is meshed on the lower side of the driving gear 310. The driving gear 310 is rotationally driven and controlled by the sliding of the rack 311.

[0051] like Figures 2 to 3 As shown, a fixed plate 312 is fixedly connected between the rack 311 and the sliding workbench 201. The fixed plate 312 plays the role of connecting the rack 311 and the sliding workbench 201, so that the rack 311 can move synchronously with the sliding of the sliding workbench 201.

[0052] like Figures 4 and 5 As shown, a flow-guiding linkage mechanism 4 is assembled within the processing box 1 and is used to perform negative pressure positioning or positive pressure ejection on the centrifugal oscillating prefabrication unit. The flow-guiding linkage mechanism 4 includes a pair of air delivery plates 401, each fixedly mounted beneath the pair of sliding worktables 201. The air delivery plates 401 are rotatably connected to the multiple sets of drive shafts 212. Air is delivered to the multiple sets of drive shafts 212 via the air delivery plates 401.

[0053] Specifically, the lower ends of the multiple groups of driving shafts 212 are each provided with an air inlet hole, a guide air duct is provided in the linkage rod 208, and a plurality of evenly distributed guide holes are provided above the carrier platform 209, and the plurality of guide holes are all connected to the guide air duct.

[0054] A pair of air delivery plates 401 are each provided with an air delivery channel, which is communicated with the air inlet.

[0055] like Figures 4 and 5 As shown, a pair of communicating air pipes 402 are connected below each of the pair of air delivery plates 401.

The ends of the communicating air pipes 402, away from the air delivery plates 401, are fixedly connected to the dustproof sleeves 403, which are sleeved around the outer sides of the guide light rods 205. The dustproof sleeves 403 not only protect the guide light rods 205 from dust, but also compress the space between them by squeezing them, allowing the air between them to be transported along the communicating air pipes 402 into the air delivery plates 401.

[0056] A method for using cement precast part processing equipment includes the following steps: according to the external features of the cement precast part mold, a plurality of positioning blocks 210 are fixed above a carrier 209; when the cement precast part is cast and formed, a plurality of cement precast part molds can be placed above a plurality of carriers 209; the cement precast part molds are clamped and positioned by the plurality of positioning blocks 210; then, the threaded cooperation between the screw rod 202 and the slider 203 can drive the sliding workbench 201 to slide in the processing box seat 1; and the sliding of the sliding workbench 201 can move the cement precast part mold to the bottom of the guide pipe 102.

[0057] The mixed cement can be poured into the cement precast mold along the guide pipe 102. During the pouring and molding process, the transmission shaft 215 is driven by the synchronous belt 217, so that the multiple sets of driving shafts 212 can drive the multiple sets of carrier platforms 209 to rotate under the cooperation of the transmission shaft 215 and the synchronous pulley 216. At the same time, during the rotation of the multiple sets of carrier platforms 209, the cement in the cement precast mold is vibrated by centrifugal oscillation through the cooperation of the oscillation protrusion 211 and the oscillation protrusion.

[0058] When the cement pouring is completed, the sliding workbench 201 is driven to slide by controlling the operation of the screw motor 204. During the sliding process of the sliding workbench 201, the driving gear 310, the rack 311, the linkage pulley 308 and the linkage belt 309 are used to drive the plurality of knocking shafts 304 to rotate. The trowel plate 301 is knocked by a plurality of knocking balls 307 so that the trowel plate 301 can resonate under the vibration of the resonance reed 303, and the upper end surface of the cement prefabricated part mold can be resonantly scraped and leveled by the trowel plate 301.

[0059] In addition, during the period when the sliding workbench 201 slides to the bottom of the guide tube 102, the space between the dustproof sleeve 403 and the guide light rod 205 gradually increases, so that the outside air can flow between the dustproof sleeve 403 and the guide light rod 205 along the guide holes, guide air ducts, air inlets and conveying air ducts above the carrier 209, so that the guide holes above the carrier 209 are in a negative pressure state. This state can negatively position the cement prefabricated part mold placed on the carrier 209, thereby ensuring the stability of the moving and conveying of the cement prefabricated part mold.

[0060] When the sliding workbench 201 slides to the disassembly position, the space between the dustproof sleeve 403 and the guide light rod 205 gradually decreases, so that the air between the dustproof sleeve 403 and the guide light rod 205 will be continuously ejected along the guide hole on the carrier platform 209. The cement precast mold can be pneumatically ejected through the continuous air jet through the guide hole, which not only improves the convenience of subsequent disassembly of the cement precast mold, but also assists in vibrating the cement in the cement precast mold through gas lifting.
