DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-6As shown, the utility model provides a technical solution: an automatic mixing and stirring concrete storage bin, comprising a bin body 1, the bin body 1 is cylindrical, and the bottom of the bin body 1 is connected to a leg at a high level, a feed hopper 2 is fixedly connected to the top of the bin body 1, a water injection pipe is fixedly connected to the side wall of the bin body 1, a rotating rod 4 is arranged in the bin body 1, and stirring blades are arranged on the left and right sides of the rotating rod 4, a motor 3 is fixedly connected to the top of the bin body 1, and the top end of the rotating rod 4 extends to the outside of the bin body 1 and is fixedly connected to the output end of the motor 3, and a sieve plate 7 is fixedly connected in the bin body 1, The sieve plate 7 is located above the stirring blade, the rotating rod 4 passes through the sieve plate 7 and is movably connected to the sieve plate 7, a movable block 6 is provided above the sieve plate 7, a groove is provided at the bottom of the movable block 6, and a roller 18 is movably connected in the groove, the bottom of the roller 18 is in contact with the sieve plate 7, a fan-shaped opening is provided on the sieve plate 7, the water injection pipe is located below the sieve plate 7, a discharge port is provided at the bottom of the bin body 1, a cylinder 14 is fixedly connected to the bottom of the bin body 1, a cover plate 13 is fixedly connected to the telescopic end of the cylinder 14, the cover plate 13 is located at the discharge port and in contact with the bottom of the bin body 1.

[0025] According to the overall structure of the device, raw materials are fed into the feed hopper 2, and the block parts are screened by the screen plate 7. The motor 3 drives the rotating rod 4 to rotate, thereby driving the roller 18 to rotate to crush the lumps. At the same time, the rotating rod 4 drives the stirring blade to rotate to stir and mix the raw materials into concrete, which is stored in the warehouse body 1. When in use, the cylinder 14 drives the cover plate 13 to move to open the discharge port to discharge the concrete.

[0026] like Figure 5 As shown, the stirring blade includes a vertically arranged rotating shaft 11, and two spirally arranged fixing plates 10 are provided on the outer side of the rotating shaft 11, and the two fixing plates 10 are centrally symmetrically arranged, and the top and bottom of the two fixing plates 10 are fixedly connected with a connecting plate 19, and the connecting plate 19 is fixedly connected to the rotating rod 4.

[0027] The two spiral fixing plates 10 increase the body range of the stirring blade, so that the stirring blade has a larger contact surface with the concrete when rotating, thereby stirring the peripheral concrete and preventing the peripheral concrete from solidifying.

[0028] like Figure 1 , 5 As shown, L-shaped scrapers 9 are provided on the back sides of the two stirring blades, the two scrapers 9 are fixedly connected to the connecting plate 19 of the stirring blades, and the outer sides of the two scrapers 9 are in contact with the inner wall of the bin body 1.

[0029] The scraper 9 rotates along with the rotating rod 4 to scrape off the concrete adhering to the inner wall of the silo 1, thereby preventing the concrete from remaining and solidifying on the inner wall of the silo 1 and affecting its use.

[0030] like Figure 1 , 5As shown, a first gear 12 is fixedly connected to the rotating rod 4, and the first gear 12 is located above the stirring blade. Second gears 8 are meshed on both sides of the first gear 12. The rotating shaft 11 of the stirring blade is movably connected to the connecting plate 19, and the top end is fixedly connected to the adjacent second gear 8.

[0031] The stirring blades are caused to rotate by themselves in the process of following the rotation of the rotating rod 4 through the first gear 12 and the second gear 8, thereby driving the flow of the concrete inside and outside, enhancing the mixing and stirring of the concrete at different layers, and improving the stirring effect.

[0032] like Figure 4 As shown, the side wall of the silo 1 is a double-layer structure, and a spray pipe 5 is fixedly connected inside the side wall, and a water inlet pipe that runs through the side wall of the silo 1 is fixedly connected to the spray pipe 5. The spray pipe 5 is arranged in a ring shape, and a plurality of evenly distributed nozzles are fixedly connected to the bottom of the spray pipe 5.

[0033] Water is transported to the spray pipe 5 through the water inlet pipe and sprayed out, thereby cooling the bin body 1 and the concrete to prevent the concrete from losing moisture due to excessive temperature and affecting its use, and the interlayer of the side wall prevents the sprayed water from entering the concrete and affecting its structure.

[0034] like Figure 2 , 4 As shown, a circulation pump 17 is fixedly connected to the outside of the silo body 1, and a return pipe 16 is fixedly connected to the bottom of the silo body 1. The return pipe 16 is connected to the circulation pump 17 and is fixedly connected to the water inlet pipe.

[0035] The sprayed water is returned to the spray pipe 5 by the circulation pump 17, so as to be recycled and save water resources.

[0036] like Figure 3 As shown, two linear guide rails 15 are fixedly connected to the bottom of the warehouse body 1 , and the two linear guide rails 15 are distributed on both sides of the cover plate 13 . Slide blocks are fixedly connected to both sides of the cover plate 13 , and the slide blocks are slidably connected to adjacent linear guide rails 15 .

[0037] The cover plate 13 is supported by the linear guide rail 15 to prevent the cover plate 13 from falling off and enable the cover plate 13 to move smoothly.

[0038] Working principle: When in use, the device is connected to an external power supply, and raw materials are poured from the feed hopper 2. The raw materials fall on the sieve plate 7, and the lumps of cement and sand are screened out through the sieve plate 7. At this time, the motor 3 drives the rotating rod 4 to rotate, and drives the movable block 6 to rotate. The movable block 6 pushes the stone to fall from the fan-shaped opening, and the agglomerated cement and sand are crushed by the roller 18 to make them dispersed and fall from the sieve hole. Then water is added to the bin body 1 from the water injection pipe, and the stirring blade is driven to rotate by the rotating rod 4 to mix and stir the raw materials into concrete. The rotating rod 4 While rotating, the first gear 12 and the second gear 8 drive the stirring blade to rotate, so that the mixing is uniform and sufficient. The mixed concrete is stored in the silo 1. When it is needed, the cover 13 is moved by the cylinder 14 to open the discharge port to discharge the concrete. In hot weather, the water inlet pipe transports water into the delivery pipe, and sprays it from the nozzle into the interlayer of the side wall of the silo 1 to reduce the temperature of the silo 1 and the concrete. At the same time, the circulation pump 17 returns the sprayed water to the water inlet pipe through the reflux pipe 16, and enters the spray pipe 5 again for spraying, thereby recycling and saving water resources.
