[0002] Precast slabs are floor slabs used in early construction. They are modules or panels used in engineering projects. Precast slabs are precast concrete components that are manufactured and processed in a prefabrication plant and then transported directly to the construction site for installation. That's why they are called precast slabs. Precast slabs have many uses in construction, such as cement slabs covering ditches along roadsides and cement slabs used as insulation layers on roofs.

[0023] Example:
[0024] Reference Figures 1-4 This utility model provides a precast concrete slab production equipment, including a base 1 and a tank 4 for storing concrete installed on the top of the base 1. It also includes: a chute 201, which is opened at the bottom of the base 1, wherein a slider 202 is slidably installed inside the chute 201, and a driving part for driving the slider 202 to slide laterally is provided on the base 1; a fixing plate 301 installed at the bottom of the slider 202, wherein a scraper 303 is slidably installed at the bottom of the fixing plate 301, and a connecting part is provided on the base 1. When the driving part drives the slider 202 to slide, the connecting part drives the scraper 303 to vibrate laterally, and the scraper 303 vibrates in the horizontal and vertical directions of the lateral movement of the slider 202.
[0025] During operation, the slider 202 is driven by the drive unit to move laterally along the slide 201. The slider 202 drives the scraper 303 to move laterally through the fixed plate 301 to scrape the concrete on the top of the mold. Under the drive of the connecting part, the scraper 303 is driven to reciprocate and vibrate in the horizontal and vertical directions of its movement, resulting in better scraping effect, reduced labor intensity and improved production efficiency of precast slabs.
[0026] The drive unit includes a first motor 203 fixedly connected to the side wall of the base 1. A lead screw 204 is fixedly connected to the output end of the first motor 203. The lead screw 204 is rotatably connected to the base 1 via a bearing. The lead screw 204 is disposed in a slide groove 201 and is horizontally arranged. A slider 202 is threadedly connected to the lead screw 204. The connection unit includes a horizontally arranged guide rod 302 fixedly connected between the inner walls of the fixing plate 301. The guide rod 302 is perpendicular to the lead screw 204. A sliding block 304 is slidably mounted on the guide rod 302. The bottom of the sliding block 304 is fixedly connected to the top of the scraper 303. A spring 305 is installed between the sliding block 304 and the inner wall of the fixing plate 301. A mounting plate 306 is fixedly connected to the bottom of the base 1. The side of the mounting plate 306 closest to the scraper 303 is fixed. The device is connected to a plurality of protrusions 307, which are equidistantly arranged. The number of protrusions 307 is 16-20, preferably 18. The side of the protrusions 307 near the scraper 303 is arc-shaped. A connecting rod 308 is fixedly connected to the side of the scraper 303 near the mounting plate 306. The end of the connecting rod 308 near the mounting plate 306 is hemispherical. The protrusions 307 are arranged on the moving path of the connecting rod 308. A vertically arranged first cylinder 5 is fixedly connected to the bottom of the slider 202. The fixed plate 301 is fixedly connected to the telescopic end of the first cylinder 5. A telescopic rod 6 is fixedly installed between the top of the fixed plate 301 and the bottom of the slider 202. The telescopic rod 6 is used to provide auxiliary support for the fixed plate 301 and the scraper 303, thereby improving the stability of the scraper 303 during the process of leveling concrete.
[0027] During operation, the first cylinder 5 is activated, and its telescopic end drives the fixed plate 301 to descend. The fixed plate 301 drives the scraper 303 to descend, so that the scraper 303 contacts the top of the mold. The first motor 203 is activated, and its output end drives the lead screw 204 to rotate. The lead screw 204 drives the slider 202 to slide laterally along the slide groove 201. The slider 202 drives the fixed plate 301 and the scraper 303 to move laterally. The fixed plate 301 drives the connecting rod 308 to move laterally. When the connecting rod 308 passes the protrusion 307, it is squeezed by the protrusion 307, so that the connecting rod 308 drives the scraper 303 to move laterally. The scraper 303 drives the sliding block 304 to slide along the guide rod 302 and compress the spring 305. Then the spring 305 returns to its original position, so that the scraper 303 continuously vibrates laterally to smooth the concrete.
[0028] The tank body 4 is provided with an inlet pipe 7 and an outlet pipe 8 at the top and bottom, respectively. An electromagnetic valve is installed on the outlet pipe 8 to control the discharge. A hose 9 is fixedly connected to the lower end of the outlet pipe 8, and a discharge pipe 10 is fixedly connected to the other end of the hose 9. The hose 9 is long enough to allow the discharge pipe 10 to move laterally. A horizontally set second cylinder 11 is fixedly connected to the bottom of the base 1. The discharge pipe 10 is fixedly connected to the telescopic end of the second cylinder 11. A stirring rod 13 is rotatably installed inside the tank body 4 via a stirring shaft 12. A second motor 14 is fixedly connected to the top of the tank body 4, and the stirring shaft 12 is fixedly connected to the output end of the second motor 14.
[0029] During operation, concrete is fed into tank 4, and the second motor 14 is started. Its output end drives the mixing rod 13 to rotate through the mixing shaft 12 to mix the concrete and prevent it from setting. Then, the solenoid valve on the discharge pipe 8 is opened, and the concrete is poured into the mold through the discharge pipe 8, hose 9 and discharge pipe 10. The second cylinder 11 is started, and its telescopic end drives the discharge pipe 10 to move laterally, which can adjust the pouring position and make the pouring more uniform.
[0030] When using this precast concrete slab production equipment, the mold is transported to the bottom of the base 1, the second motor 14 is started, and its output end drives the mixing rod 13 to rotate through the mixing shaft 12 to mix the concrete and prevent it from setting. Then, the solenoid valve on the discharge pipe 8 is opened, and the concrete is poured into the mold through the discharge pipe 8, the hose 9 and the discharge pipe 10. The second cylinder 11 is started, and its telescopic end drives the discharge pipe 10 to move laterally, which can adjust the pouring position and make the pouring more uniform.
[0031] Next, the first cylinder 5 is started, and its telescopic end drives the fixed plate 301 to descend. The fixed plate 301 drives the scraper 303 to descend, so that the scraper 303 contacts the top of the mold. The first motor 203 is started, and its output end drives the lead screw 204 to rotate. The lead screw 204 drives the slider 202 to slide laterally along the slide groove 201. The slider 202 drives the fixed plate 301 and the scraper 303 to move laterally. The fixed plate 301 drives the connecting rod 308 to move laterally. When the connecting rod 308 passes the protrusion 307, it is squeezed by the protrusion 307, so that the connecting rod 308 drives the scraper 303 to move laterally. The scraper 303 drives the sliding block 304 to slide along the guide rod 302 and compress the spring 305. Then the spring 305 returns to its original position, so that the scraper 303 continuously vibrates laterally to smooth the concrete.
