The scraper 3 can not only fully mix the cement, sand and gravel aggregates, water and other materials, but also effectively clean the materials adhering to the inner wall of the mixing drum 1.

[0033] According to a further optimized solution, the telescopic portion includes a fixed cylinder 32 fixedly connected to the circular tube 2 , a movable rod 31 is slidably connected inside the fixed cylinder 32 , and one end of the movable rod 31 extending outside the fixed cylinder 32 is fixedly connected to the scraper 3 .

[0034] A further optimized solution is that one end of the movable rod 31 extending into the fixed cylinder 32 is fixedly connected to a limit plate 33, and one end of the limit plate 33 facing away from the movable rod 31 is fixedly connected to a spring 34. The limit plate 33 is arranged in the fixed cylinder 32 and is slidably connected to the fixed cylinder 32.

[0035] The limit plate 33 is pushed by the elastic force of the spring 34 , the limit plate 33 pushes the movable rod 31 , and the movable rod 31 pushes the scraper 3 , so that the scraper 3 is in close contact with the inner wall of the mixing drum 1 .

[0036] According to a further optimization scheme, arc-shaped triangular blocks 35 are symmetrically arranged on one side of the scraper 3 , the arc-shaped triangular blocks 35 are slidably connected to the inner wall of the mixing drum 1 , and the tips of the two arc-shaped triangular blocks 35 are arranged toward the discharge pipe 12 .

A valve is arranged in the discharge pipe 12. When the concrete is mixed, the valve can be opened to collect the mixed concrete.

[0038] Further optimization scheme, the outer wall of the round tube 2 extending into the mixing drum 1 is provided with a plurality of water outlet holes 23, and the plurality of water outlet holes 23 are evenly distributed on the round tube 2, and one end of the round tube 2 extending outside the mixing drum 1 is rotatably connected to the movable end of the flexible joint 22, and the fixed end of the flexible joint 22 is fixedly connected to the outer wall of the mixing drum 1, and the other end of the round tube 2 extending outside the mixing drum 1 is transmission-connected to the motor 21, and the motor 21 is fixedly connected to the outer wall of the mixing drum 1. The end of the flexible joint 22 away from the round tube 2 is connected to the water outlet of the water pump, and the water inlet of the water pump is connected to the water source.

[0039] In order to effectively improve the accuracy of the proportions of materials such as cement, sand and gravel aggregates and water with different proportions, after all batches of materials with the same proportion are mixed, before mixing materials with different proportions, turn on the water pump, and the water pump transports water from the water source to the circular tube 2 through the flexible joint, and the water in the circular tube 2 is sprayed out through the water outlet 23. At this time, the motor 21 is turned on synchronously, and the motor 21 drives the circular tube 2 to rotate, and the circular tube 2 drives the fixed cylinder 32 to rotate, and the fixed cylinder 32 drives the movable rod 31 to rotate, and the movable rod 31 drives the scraper 3 to rotate. The scraper 3 can clean up the residual materials adhering to the inner wall of the mixing drum 1, so that there is no adhering materials on the inner wall of the mixing drum 1.

[0040] The water pump can also effectively deliver the liquid into the mixing drum 1 according to the required amount.

[0041] A further optimized solution is that the conveying assembly includes a shaftless screw conveyor 5 fixedly connected to the outer wall of the mixing drum 1, the discharge end of the shaftless screw conveyor 5 is fixedly connected and connected to a discharge pipe 51, the discharge end of the discharge pipe 51 is arranged above the feed hopper 11, the feed end of the shaftless screw conveyor 5 is arranged at the bottom of the shaftless screw conveyor 5, and the feed end of the shaftless screw conveyor 5 is connected to the discharge port 41 through a hose.

[0042] The discharge pipe 51 is tilted, with the higher end of the discharge pipe 51 located at the discharge end of the shaftless screw conveyor 5 , and the lower end of the discharge pipe 51 located above the feed hopper 11 , so that the material can enter the feed hopper 11 along the discharge pipe 51 .

[0043] The shaftless screw conveyor 5 can vertically convey materials such as cement, sand and gravel aggregates and water, so that the materials can enter the mixing drum 1 through the feed hopper 11 .

[0044] A further optimized solution is that the material blocking assembly includes a movable plate 44 detachably connected to the discharge port 41, the movable plate 44 is slidably connected to the inner wall of the feed box 4, the end of the movable plate 44 extending outside the top surface of the feed box 4 is fixedly connected to a connecting rod 43, the end of the connecting rod 43 away from the movable plate 44 is fixedly connected to the telescopic end of the electric telescopic rod 42, and the fixed end of the electric telescopic rod 42 is embedded in the side wall of the feed box 4.

[0045] When weighing is required, the telescopic end of the electric telescopic rod 42 is retracted, so that the movable plate 44 can effectively block the discharge port 41 to prevent materials such as cement, sand and gravel aggregates and water from falling into the shaftless screw conveyor 5. After weighing is completed, the telescopic end of the electric telescopic rod 42 is extended, and the movable plate 44 rises, so that the movable plate 44 does not block the discharge port 41, allowing the material to enter the shaftless screw conveyor 5 through the discharge port 41.

[0046] Further optimized solution, the push assembly includes a push plate 46 arranged in the feed box 4, the lower part of the push plate 46 facing the movable plate 44 is fixedly connected with a fixed block 47, the fixed block 47 is adapted to the discharge port 41, the middle part of the push plate 46 facing away from the fixed block 47 is fixedly connected with the piston end of the hydraulic cylinder 45, and the fixed end of the hydraulic cylinder 45 is fixedly connected to the outer wall of the feed box 4. When the push plate 46 is not working, it abuts against the side wall opposite to the discharge port 41, so that after the material enters the feed box 4, it is between the movable plate 44 and the push plate 46.

[0047] When the material is weighed, in order to allow the material to effectively enter the discharge port 41, the piston end of the hydraulic cylinder 45 extends to move the push plate 46 toward the discharge port 41. When the push plate 46 abuts against the movable plate 44, the fixed block 47 is in the discharge port 41, allowing the material to completely enter the discharge port 41.

[0048] In order to prevent materials from entering the gap between the push plate 46 and the feed box 4, which would cause the extension and retraction of the piston end of the hydraulic cylinder 45 to be blocked, the end of the push plate 46 extending outside the feed box 4 is fixedly connected to an inclined plate, and the lower end of the inclined plate is located at the top surface of the push plate 46, which effectively prevents materials from entering the gap between the push plate 46 and the feed box 4.

[0049] According to a further optimization scheme, the discharge port 41 is arranged higher than the feed end of the shaftless screw conveyor 5 .

[0050] The discharge port 41 is arranged at an angle, with the lower end of the discharge port 41 facing the shaftless screw conveyor 5. When the discharge port 41 is higher than the feed end of the shaftless screw conveyor 5, the hose is in an inclined state, allowing the material to enter the feed end of the shaftless screw conveyor 5 along the hose.

[0051] The hose can effectively avoid and adapt to the up and down floating of the weighing element 48, so that the material can effectively enter the feeding end of the shaftless screw conveyor 5 through the hose.

[0052] Working process: first, the telescopic end of the electric telescopic rod 42 is retracted so that the movable plate 44 can effectively block the discharge port 41, and at the same time, the piston end of the hydraulic cylinder 45 is retracted so that the push plate 46 abuts against the side wall opposite to the discharge port 41, and then, according to the requirements of the material ratio of cement, sand and gravel aggregates, any one of the materials such as cement, sand and gravel aggregates is poured into the feed box 4, and the material in the feed box 4 is weighed by the weighing piece 48. After reaching the required weight, the telescopic end of the electric telescopic rod 42 is extended, and the movable plate 44 rises so that the movable plate 44 does not block the discharge port 41, and then, the piston end of the hydraulic cylinder 45 is extended to move the push plate 46 toward the discharge port 41. When the push plate 46 abuts against the movable plate 44, at this time, the fixed block 47 is in the discharge port 41, so that the material can completely enter the discharge port 41. When all the materials in the feed box 4 enter the discharge port 41, the above process is repeated to weigh different materials.

[0053] Then the shaftless screw conveyor 5 conveys the material to the discharge pipe 51, and the material falls from the discharge pipe 51 into the feed hopper 11 and enters the mixing drum 1. At this time, the valve of the discharge pipe 12 is always in a closed state, the motor 21 drives the round tube 2 to rotate, the round tube 2 drives the fixed drum 32 to rotate, the fixed drum 32 drives the movable rod 31 to rotate, and the movable rod 31 drives the scraper 3 to rotate. The scraper 3, the fixed drum 32, and the movable rod 31 can stir the material in the mixing drum 1, and the scraper 3 can also The materials adhering to the inner wall of the mixing drum 1 are cleaned to make the inner wall of the mixing drum 1 free of materials adhering thereto so that the materials can be fully mixed. When all materials such as cement, sand and gravel aggregates enter the mixing drum 1, the required amount of water is delivered by a water pump, and the water pump delivers the water to the circular pipe 2 through a flexible joint. The water in the circular pipe 2 is sprayed out through a water outlet 23 so that the water can be mixed and stirred with the materials in the mixing drum 1. After the mixing is completed, the valve on the discharge pipe 12 is opened to collect the mixed concrete.

[0054] The present invention uses the shaftless screw conveyor 5 to convey solid materials, and the water pump is used to convey liquids, so that the shaftless screw conveyor 5 will not cause materials to adhere to the spiral blades of the shaftless screw conveyor 5 due to conveying liquids.

[0055] When all batches of materials with the same ratio are mixed, before mixing materials with different ratios, turn on the water pump, and the water pump transports water from the water source to the circular tube 2 through the flexible joint, and the water in the circular tube 2 is sprayed out through the water outlet 23. At this time, the motor 21 is turned on synchronously, and the motor 21 drives the circular tube 2 to rotate, and the circular tube 2 drives the fixed cylinder 32 to rotate, and the fixed cylinder 32 drives the movable rod 31 to rotate, and the movable rod 31 drives the scraper 3 to rotate. The scraper 3 can clean the residual material adhering to the inner wall of the mixing drum 1, so that there is no material adhering to the inner wall of the mixing drum 1.
