Background
At present, the ice rink is also called as an ice rink, and an ice layer is mostly obtained by artificial ice making, so that the natural ice surface can be restored to the maximum extent, and good entertainment experience is provided for users.
Chinese patent No. CN209816601U discloses an ice sheet cracking-proof structure for ice rinks, which comprises a plurality of partition boards arranged in a coil sand layer, wherein the bottom ends of the partition boards are connected with an anti-freezing concrete layer, and the top ends of the partition boards are positioned above the coil sand layer; the ice board can be effectively protected under the condition that the thickness of the ice layer is limited, so that the ice board is not easy to crack; when the ice layer receives the impact and produces vibrations, viscoelasticity damping piece can in time dissipate the energy, prevents the effect of vibrations energy accumulation with the ice layer destruction.
Among the above-mentioned prior art, the ice surface mainly divide into concrete layer, coil pipe sand layer, baffle layer and ice sheet of preventing frostbite, and concrete layer, coil pipe sand layer, baffle layer and ice sheet of preventing frostbite arrange from bottom to top in proper order moreover.
When carrying out the arrangement of ice surface, arrange good with the concrete layer that prevents frostbite earlier, then lay the coil pipe sand bed on the concrete layer that prevents frostbite to fixed baffle layer on the coil pipe sand bed, later spread the material of ice sheet on the baffle layer again, cover the baffle layer, make level, guarantee the surfacing of ice sheet, carry out the freeze treatment to the ice sheet at last again, make the ice sheet material solidify the shaping.
As shown in fig. 1 and 2, when an ice layer is formed, a spreading machine is generally used to form the ice layer, and the ice layer material is in a slurry state when not solidified. The paver comprises a machine body 1, wherein a material bearing box 2 is arranged in the machine body 1, and ice layer materials are placed in the material bearing box 2. Fixedly connected with conveying pipeline 3 on organism 1, install screw conveyer 4 on conveying pipeline 3, and conveying pipeline 3 and the downside fixed connection who holds workbin 2, conveying pipeline 3 and the inside intercommunication that holds workbin 2, install the control valve on conveying pipeline 3, open the control valve, the ice sheet material that holds in the workbin 2 gets into conveying pipeline 3 under the effect of self gravity in, the ice sheet material that gets into in conveying pipeline 3 advances in conveying pipeline 3 under bolt conveyer's effect.
At the other end fixedly connected with discharging device 5 of conveying pipeline 3, during the ice layer material gets into discharging device 5 in the conveying pipeline 3, discharging device 5 was discharged the ice layer material and was spread on the baffle layer, and wherein, discharging device 5 enlarges the area that the ice layer material paved, still installs the pressure flat board 6 on discharging device 5, flattens the ice layer material that paves, lets paving of ice layer material more level and smooth.
