Problems solved by technology

[0002] The cement manhole cover is made by adding a certain proportion of steel brazing fiber to the cement, which is controlled by the manhole cover mold. It is more compressive than the iron manhole cover, and will not reduce the service life due to the corrosion of rainwater and other things. When making cement For manhole covers, it is necessary to manually set up a shovel to level the surface; traditional cement manhole cover leveling devices generally rely on manual leveling, so the labor intensity is relatively high, and the cement slurry cannot be completely leveled. At the same time, in the manufacturing process of cement manhole covers, there are a lot of air bubbles in the cement slurry, so these air bubbles will reduce the quality of cement manhole covers

Embodiment 1

[0039] Such as figure 1 , image 3 , Figure 5 , Image 6 , Figure 7 , Figure 8 As shown, the lifting mechanism 3 includes a lifting frame 31, a support base 32, and a lifting cylinder 33. The fixed part of the lifting cylinder 33 is connected to the front and rear sides of the support frame 6 by bolts. The support seat 32 is connected to the middle position of the lifting frame 31 by welding, and the lifting frame 31 is driven by the telescopic part of the lifting cylinder 33 to lift, and the support seat 32 from the lifting frame 31 is lifted to drive the mold 7 to lift and smooth Conveying mechanism 4 comprises the first conveying roller 41, conveying motor 42, pulley 43, belt 44, the second conveying roller 45, the 3rd conveying roller 46, the first conveying roller 41, the 2nd conveying roller 45 and the 3rd conveying roller 46 are all connected to the inner side of the base 5 through bearings, the third conveying roller 46 is located on one side of the second conv...

Embodiment 2

[0042] Such as figure 2 , Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the lifting mechanism 3 includes a lifting frame 31, a support base 32, a lifting motor 313, and a lead screw 314. The lifting motor 313 is connected to the front and rear sides of the support frame 6 by bolts. The upper and lower ends of the bar 314 are connected to the front and rear sides of the support frame 6 through bearings. The leading screw 314 is located below the lifting motor 313. The front and rear ends of the lifting frame 31 are connected to the outside of the leading screw 314 by threads. In the middle position of the lifting frame 31, the rotating part of the lifting motor 313 is used to drive the screw 314 to rotate, and the rotation of the screw 314 drives the lifting frame 31 to go up and down, and the support seat 32 from the lifting frame 31 is lifted to drive the mold 7. Carry out lifting and troweling.

Abstract

The invention discloses a smoothing device for the manufacture of cement manhole covers, which includes a lifting mechanism for driving the cement manhole cover to lift, a conveying mechanism, a base, a support frame, and a mould. The lifting mechanism is arranged on the front and rear sides of the support frame, the conveying mechanism is arranged on the inside of the base, the mold is located inside the support frame, and it also includes a smoothing mechanism and a vibration mechanism. The invention uses a troweling motor to drive the rotating seat to rotate, and drives the troweling plate to smooth the cement manhole cover through the rotating rod at the lower end of the rotating seat, thereby improving the entire troweling efficiency. The vibrating cylinder is used to drive the vibrating seat to reciprocate. The movement of the seat is used to discharge the excess air bubbles in the cement slurry in the mold, thereby improving the quality of the entire cement manhole cover.

technical field [0001] The invention relates to the field of cement manhole cover manufacture, in particular to a smoothing device for cement manhole cover manufacture. Background technique [0002] The cement manhole cover is made by adding a certain proportion of steel brazing fiber to the cement, which is controlled by the manhole cover mold. It is more compressive than the iron manhole cover, and will not reduce the service life due to the corrosion of rainwater and other things. When making cement For manhole covers, it is necessary to manually set up a shovel to level the surface; traditional cement manhole cover leveling devices generally rely on manual leveling, so the labor intensity is relatively high, and the cement slurry cannot be completely leveled. At the same time, in the cement manhole cover manufacturing process, the cement mud contains a lot of air bubbles, so these air bubbles will reduce the quality of the cement manhole cover.
