The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion, and the cement concrete obtained by mixing is widely used in civil engineering. Loading is required during the concrete production process.

[0003] For example, a Chinese patent discloses: an automatic feeding device for building concrete materials, patent number: CN218083397U, which is equipped with a stirring mechanism and a spiral conveying blade, and utilizes the output shaft at the upper end of the dual-axis motor to rotate to drive the second transmission wheel to rotate, and then uses the transmission belt to make the first transmission wheel drive the stirring rod to rotate, so that the rotation of the stirring rod drives the stirring blade to rotate, thereby achieving the mixing of concrete materials.

[0004] However, in the process of implementing the above technical solution, it was found that there were at least the following technical problems: the device lacked a screening function, which made it easy for raw materials with large particles that were not fully broken up during the feeding process to be transported to concrete production, forming lumps or aggregates in the concrete, resulting in insufficient uniformity of the concrete and insufficient local strength in the concrete, thereby affecting the overall strength and stability of the concrete.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0025] Embodiment

[0026] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the device lacks a screening function, and it is easy for raw materials with large particles not fully dispersed in the feeding process to be transported to concrete production, forming lumps or aggregations in the concrete, resulting in insufficient uniformity of the concrete and causing local strength deficiency in the concrete, thereby affecting the overall strength and stability of the concrete. The general idea is as follows: It includes a device main body 11, a feeding hopper 12 is fixedly connected to the upper end of the device main body 11, a discharging hopper 13 is fixedly connected to the lower end of the device main body 11, a conveyor 14 is movably connected to the lower end of the device main body 11, the conveyor 14 is located at the lower end of the discharging hopper 13, and the raw materials for cement production are put into the device main body 11 through the feeding hopper 12, screened and then discharged to the conveyor 14 through the discharging hopper 13, and the feeding is driven by the conveyor 14 to achieve the purpose of automatic feeding and save labor intensity.

[0027] Inside the device main body 11, a feeding pipe 15 is fixedly connected. The feeding pipe 15 is located at the lower end of the feeding hopper 12. On one side of the device main body 11 close to the feeding hopper 12, a motor 16 is fixedly connected. On one side of the motor 16 close to the feeding hopper 12, a screening mechanism is fixedly connected. The screening mechanism includes a spiral conveyor rod 17. The spiral conveyor rod 17 is fixedly connected to one side of the motor 16 close to the feeding hopper 12. On the outer surface of the spiral conveyor rod 17, a support frame 18 is fixedly connected. A drum sieve 19 is sleeved on the outer surface of the support frame 18. The drum sieve 19 and the feeding pipe 15 are on the same horizontal line. A discharge chute 21 is opened inside the device main body 11. A collection box 22 is clamped inside the device main body 11. The collection box 22 is located at the lower end of the discharge chute 21. When the motor 16 is started, the motor 16 drives the spiral conveyor rod 17 to rotate, and the material is pushed into the drum sieve 19 through the feeding pipe 15. The spiral conveyor rod 17 drives the drum sieve 19 to rotate through the support frame 18, and the material is screened. The large-particle and insufficiently dispersed material is discharged forward through the discharge chute 21 into the collection box 22 for collection and recycling, avoiding the large-particle material from being fed into the concrete production, which is beneficial to improving the uniformity of the production raw materials and the stability of the concrete strength.

[0028] On the side of the outer surface of the spiral conveyor rod 17 far from the motor 16, a first gear 23 is fixedly connected. A rotating rod 24 is rotatably connected inside the device main body 11. On the outer surface of the rotating rod 24, a second gear 25 is fixedly connected. The second gear 25 meshes with the first gear 23. A brush roller 26 is sleeved on the outer surface of the rotating rod 24.

During the rotation and screening process of the drum sieve 19, the spiral conveyor rod 17 drives the first gear 23 to rotate, and the first gear 23 drives the rotating rod 24 to rotate by meshing with the second gear 25. Due to the opposite rotation directions generated by the meshing of the two gears, at this time, the rotating rod 24 drives the brush roller 26 and the drum sieve 19 to rotate in opposite directions to clean the drum sieve 19, avoiding the raw material from getting stuck in the gaps inside the drum sieve 19, extending the service life of the drum sieve 19, and improving the screening efficiency.

[0029] Aiming at the problems existing in the prior art, the present utility model provides an automatic feeding device for concrete production. When the motor 16 is started, the motor 16 drives the spiral conveyor rod 17 to rotate, and the material is pushed into the drum sieve 19 through the feeding pipe 15.

[0030] Working principle:

[0031] First step, the raw materials for cement production are put into the device main body 11 through the feeding hopper 12. The motor 16 is started, and the motor 16 drives the spiral conveyor rod 17 to rotate. The materials are pushed into the drum sieve 19 through the feeding pipe 15. The spiral conveyor rod 17 drives the drum sieve 19 to rotate through the support frame 18, and the materials are screened. The large-particle and insufficiently dispersed materials are discharged forward into the collection box 22 through the discharge chute 21 for collection and recycling, avoiding the feeding of large-particle materials into concrete production, which is beneficial to improving the uniformity of production raw materials and the stability of concrete strength. After the raw materials are screened, they are discharged to the conveyor 14 through the feeding hopper 13 and are fed by the conveyor 14 to achieve the purpose of automatic feeding and save labor intensity.

[0032] Second step, during the rotation and screening process of the drum sieve 19, the first gear 23 is driven to rotate by the spiral conveyor rod 17. The first gear 23 drives the rotating rod 24 to rotate by meshing with the second gear 25. Due to the opposite rotation directions generated by the meshing of the two gears, at this time, the rotating rod 24 drives the brush roller 26 and the drum sieve 19 to rotate in opposite directions to clean the drum sieve 19, avoiding the raw materials from getting stuck in the gaps of the drum sieve 19, extending the service life of the drum sieve 19, and improving the screening efficiency.
