Description

Technical Field

[0001] The utility model relates to the technical field of glasses storage, in particular to a blanking device for ready-mixed concrete. Background Technique

[0002] Ready-mixed concrete is a concrete mixture formed by mixing components such as cement, aggregates, water, and admixtures and mineral admixtures added as required in a certain proportion. There is also a phenomenon of segregation in ready-mixed concrete. Concrete segregation is a phenomenon in which the cohesion between the constituent materials of the concrete mixture is insufficient to resist the sinking of coarse aggregates, and the components of the concrete mixture are separated from each other, resulting in uneven internal composition and structure, usually manifested as large particles depositing at the bottom of the mixture.

[0003] Due to the problem of concrete segregation, when discharging concrete from a concrete storage bin, there will be a problem of uneven quality of different batches of concrete. At present, there is no good method to solve the problem of uneven blanking quality. Content of the Utility Model

[0004] To solve the problems mentioned in the background technique, the purpose of the utility model is to provide a blanking device for ready-mixed concrete.

[0005] To achieve the above goal, the technical solution of the utility model is as follows:

[0006] A blanking device for ready-mixed concrete includes a lower partition board, an inner cylinder, an upper partition board, an outer cylinder, and a motor. The lower partition board is horizontally and fixedly connected to the lower part inside the concrete storage bin. The lower partition board divides the inner cavity of the concrete storage bin into a storage bin and a premixing bin arranged up and down. A vertically upward inner cylinder is fixedly connected to the middle of the lower partition board. The inner cylinder communicates with the premixing bin. A plurality of blanking holes are evenly distributed along the circumferential direction of the inner cylinder on the lower partition board. A plurality of inner material holes are evenly distributed on the upper part of the circumferential surface of the inner cylinder. The inner material holes are strip-shaped and longitudinally arranged. The plurality of inner material holes are arranged in a staggered manner with the blanking holes. The upper partition board is stacked on the lower partition board. An outer cylinder is fixedly connected to the middle of the upper partition board. The outer cylinder is sleeved outside the inner cylinder. The upper partition board is provided with feeding holes corresponding to the plurality of blanking holes. The circumferential surface of the outer cylinder is provided with outer material holes that can match the inner material holes. The plurality of outer material holes are arranged corresponding to the feeding holes. A connecting rod is coaxially connected to the top of the outer cylinder. The connecting rod is connected to the main shaft of the motor. The motor is fixed on the top of the concrete storage bin.

[0007] Further, a feeding port is arranged at the top of the concrete storage bin, and a discharging port is arranged at the bottom. A valve is connected to the discharging port.

[0008] The beneficial effects of the present utility model are as follows: During discharging, the outer cylinder can be rotated by the motor to align the feeding hole with the discharging hole, while the inner material hole is arranged in a staggered manner with the outer material hole. At this time, only the concrete at the bottom of the storage bin passes through the feeding hole and the discharging hole and is discharged into the premixing bin. Then, the outer cylinder is rotated by the motor operation to align the inner material hole with the outer material hole, while the feeding hole is arranged in a staggered manner with the discharging hole. At this time, only the concrete at the upper part of the storage bin passes through the outer material hole and the inner material hole and is discharged into the premixing bin. By adopting the above steps, the concrete at the upper and lower parts of the storage bin can be premixed in advance during feeding, avoiding the situation that only the bottom concrete can be obtained in the previous batch of feeding and only the top concrete can be obtained in the subsequent batch of feeding, thus solving the problem of uneven quality of concrete in different batches.

Detailed Embodiments

[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the protection scope of the present utility model.

[0013] As Figure 1 - Figure 2As shown in the figure, a blanking device for ready-mixed concrete includes a concrete storage bin 1, a lower partition 2, an inner cylinder 21, an upper partition 3, an outer cylinder 31, and a motor 4. The top of the concrete storage bin 1 is provided with a feed inlet 13, and the bottom is provided with a discharge port 14. A valve 15 is installed at the discharge port 14. The lower partition 2 is horizontally and fixedly connected to the lower part inside the concrete storage bin 1. The lower partition 2 divides the inner cavity of the concrete storage bin 1 into a storage bin 11 and a premixing bin 12 which are arranged up and down. A vertically upward inner cylinder 21 is fixedly connected to the middle of the lower partition 2. The inner cylinder 21 communicates with the premixing bin 12. Two arc-shaped blanking holes 22 are evenly distributed along the circumference of the inner cylinder 21 on the lower partition 2. Two inner material holes 23 are evenly distributed on the upper part of the circumferential surface of the inner cylinder 21. The inner material holes 23 are strip-shaped and longitudinally arranged. The two inner material holes 23 are arranged in a staggered manner with the two blanking holes 22. The upper partition 3 is stacked on the lower partition 2. An outer cylinder 31 is fixedly connected to the middle of the upper partition 3. The outer cylinder 31 is sleeved outside the inner cylinder 21. The upper partition 3 is provided with a feeding hole 32 corresponding to the two blanking holes 22. Two outer material holes 33 capable of matching the inner material holes 23 are provided on the circumferential surface of the outer cylinder 31. The two outer material holes 33 are arranged corresponding to the feeding hole 32. A connecting rod 34 is coaxially connected to the top of the outer cylinder 31. The connecting rod 34 is connected to the main shaft of the motor 4. The motor 4 is installed on the top of the concrete storage bin 1 through a frame 5.

[0014] During discharging, the outer cylinder 31 is rotated by the motor 4 to make the feeding hole 32 correspond to the blanking hole 22. At the same time, the inner material hole 23 is arranged in a staggered manner with the outer material hole 33. At this time, only the concrete at the bottom of the storage bin 1 passes through the feeding hole 32 and the blanking hole 22 and is discharged into the premixing bin 12. Then, the outer cylinder 31 is rotated by the motor 4 again to make the inner material hole 23 correspond to the outer material hole 33. At the same time, the feeding hole 32 is arranged in a staggered manner with the blanking hole 22. At this time, only the concrete in the upper part of the storage bin passes through the outer material hole 33 and the inner material hole 23 and is discharged into the premixing bin 12. By adopting the above steps, the concrete in the upper and lower parts of the storage bin 1 can be premixed in the premixing bin 12 in advance during blanking, avoiding that only the bottom concrete can be obtained in the previous batch of blanking, while only the top concrete can be obtained in the subsequent batch of blanking, thus solving the problem of non-uniform quality of concrete in different batches.

[0015] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. All modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
