Technical Field
[0001] The utility model relates to the technical field of material feeding, in particular to a material feeding mechanism for concrete capable of resisting freeze-thaw cycles. Background Art
[0002] As a widely used building material, the performance and quality of concrete have always been the focus of people's attention. Freeze-thaw cycles are one of the common forms of concrete damage, especially in cold areas. Freeze-thaw cycles refer to the process in which concrete freezes in a low temperature environment and then melts at a high temperature. During the freezing process, the moisture in the concrete will form ice crystals, causing the concrete to expand. When the ice crystals expand to a certain extent, they will destroy the internal structure of the concrete, resulting in a decrease in the mechanical properties of the concrete. During the melting process, the ice crystals will gradually melt and release moisture, causing the concrete to shrink. When the ice crystals melt completely, the internal structure of the concrete will change, resulting in a decrease in the mechanical properties of the concrete. Due to the continuous repetition of freeze-thaw cycles, the degree of damage to the concrete will gradually increase, and eventually lead to the complete destruction of the concrete.
[0003] In the existing device, the concrete feeding device for resisting freeze-thaw cycles cannot feed the concrete uniformly, and the concrete for resisting freeze-thaw cycles has a large viscosity and is easy to stick to the inner wall of the mixing barrel, which increases the production cost for the user.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. This unloading mechanism for concrete that can resist freeze-thaw cycles can clean the mixing barrel by setting structures such as a mixing barrel, a barrel cover, and a spray head. If concrete is adhered to the inner wall and the bottom wall of the mixing barrel and is not cleaned in time, it will harden on the inner wall of the mixing barrel. Start the pump to pump water in the water tank into the mixing barrel through the output pipe, and evenly sprinkle it on the inner wall of the mixing barrel through the water sprinkling port on the outer ring of the spray head.

These things will enter the water tank through the transfer pipe during rainfall, causing water pollution inside the water tank. A flushing pipe is set to allow the rainfall head water to carry dust into the valve. When the valve is filled with mixed water, clean water enters the water tank through the transfer pipe. Dust and soil exist in the water inside the water tank and settle at the bottom of the water tank. An elbow is set to prevent the water coming down from the transfer pipe from impacting the soil accumulated at the bottom of the water tank. In this way, the water drawn from the water inlet pipe is clean and clear, thereby collecting and utilizing rainwater. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 7 A water tank 20 is provided on the side of the pump 17 away from the frame 1, a rain collector 21 is fixedly installed on the top of the water tank 20, a water inlet pipe 172 is fixedly connected between the water tank 20 and the pump 17, a gathering chamber 211 is provided inside the rain collector 21, a filter plate 212 is fixedly installed on the top of the rain collector 21, a filter hole is provided on the top of the filter plate 212 to prevent fallen leaves from entering the gathering chamber 211, a transfer pipe 213 is fixedly connected between the gathering chamber 211 and the inside of the water tank 20, and an elbow 214 is fixedly connected at the end of the transfer pipe 213 located in the water tank 20. When the water source inside the gathering chamber 211 enters the water tank 20 through the transfer pipe 213, there is dust and mud in the water inside the water tank 20, which is deposited at the bottom of the water tank 20.

[0028] Working principle: open the barrel cover 5, pour the well-proportioned concrete material into the mixing barrel 4, and pump the water in the water tank 20 into the mixing barrel 4 by driving the pump 17. Then start the motor 3 to drive the driving sleeve 8 to rotate. The driving sleeve 8 drives the outer scrapers 10 and the inner scrapers 15 on both sides to rotate together while rotating. The inner scraper 15 follows the driving sleeve 8 to rotate on the center side of the bottom wall of the mixing barrel 4. The outer scraper 10, the top plate 12, and the scraper plate 13 follow the driving sleeve 8 to rotate on the outer side of the bottom wall of the mixing barrel 4. The scraper plate 13 scrapes off the concrete adhering to the inner wall of the mixing barrel 4 during rotation, so that the concrete is evenly mixed on the inner wall of the mixing barrel 4. After the mixing is completed, turn the handle 161 to offset the position of the blocking plate 162 and stagger it from the discharge port, so that the concrete in the mixing barrel 4 flows out through the discharge port.
[0029] When the concrete in the mixing barrel 4 flows out, concrete adheres to the inner wall and bottom wall of the mixing barrel 4. If it is not cleaned in time, it will harden on the inner wall of the mixing barrel 4. Start the pump 17 to pump the water in the water tank 20 into the mixing barrel 4 through the output pipe 171, and evenly sprinkle it on the inner wall of the mixing barrel 4 through the sprinkler port of the outer circle of the spray head 19. Start the motor 3 again, scrape off the residual concrete on the inner wall of the mixing barrel 4, and clean the inside of the mixing barrel 4. When the rain receiver 21 is affected by rainfall, rainwater flows into the gathering chamber 211 through the filter plate 212. First, the first batch of rainwater with dust will enter the transfer pipe 213 and flow into the flushing pipe 215. The subsequent clean rainwater enters the water tank 20 through the transfer pipe 213 and is stored in the water tank 20.
