[0002] Aggregate concrete uses cement as the main binder. During the unloading process, aggregates fall from the end of the belt conveyor. Due to the large height difference with the bottom of the bin, coarse and fine particles are separated. When piled up, coarse particles tend to roll outward, resulting in a phenomenon where the range of the falling point is fine and the outside is coarse. This situation will lead to gradation variation, causing the hot material bin of a certain gear of the asphalt mixer to be full or waiting for material, affecting the stability of production efficiency and production quality.

[0023] A device for preventing material segregation when discharging aggregate in a three-dimensional silo. Figure 1-2 As shown, it includes a three-dimensional silo 100 and a material rail 200 arranged at the bottom of the three-dimensional silo 100. The three-dimensional silo 100 is provided with a feed port, and a discharge port is arranged at the bottom. When unloading, materials can be fed from the bottom of the three-dimensional silo 100, discharged through the bottom of the three-dimensional silo 100, and finally transported to a designated place through the material rail 200; in addition, the three-dimensional silo 100 can also be used as a storage silo to a certain extent.

[0024] In this embodiment, the feed port and the discharge port are not shown in the figure. The feed port can be set at the top of the three-dimensional silo 100 or at the side of the three-dimensional silo 100 and close to the top.

[0025] The material rail 200 corresponds to / is connected to the bottom of the three-dimensional material bin 100 .

[0026] like Figure 1 As shown, the three-dimensional silo 100 stands on the ground or a plane through support.

[0027] like Figure 2 As shown, the three-dimensional material bin 100 is divided into a plurality of interlayer cavities 101 by a plurality of material guide plates 110, and the plurality of interlayer cavities 101 are distributed up and down. In this embodiment, three material guide plates 110 are provided, and the interior of the three-dimensional material bin 100 is distributed into four interlayer cavities 101 from top to bottom. The material guide plates 110 are provided with a material port 111 connecting the upper and lower interlayer cavities 101.

[0028] Specifically, each material guide plate 110 is provided with two material openings 111, and the material openings 111 of adjacent material guide plates 110 do not overlap;

[0029] The material guide plate 110 is inclined toward the material port 111 , or the material port 111 is disposed at a lower position of the material guide plate 110 , so as to facilitate guiding the aggregate to flow out from the material outlet 111 .

[0030] The material openings 111 between the upper and lower adjacent material guide plates 110 are not overlapped, so as to prevent the aggregate from directly passing through the multiple material openings 111 and finally being sent out from the discharge port.

[0031] The discharge port at the bottom of the three-dimensional silo 100 is arranged at the exact center of the bottom of the three-dimensional silo 100 .

[0032] In one embodiment, a stirring rod 120 is disposed in the three-dimensional silo 100, and the stirring rod 120 is driven to rotate by a motor 130;

[0033] Furthermore, the central axis 121 passes through the plurality of material guide plates 110 from top to bottom, and the central axis 121 is disposed at the center of the three-dimensional material bin 100;

[0034] The stirring rod 120 includes a central axis 121 and a plurality of material rods 122 distributed on the central axis 121 and extending in a radial direction. The extending directions of the plurality of material rods 122 are not completely the same, and the heights of the plurality of material rods 122 are not completely the same.

[0035] like Figure 2 As shown, the central axis 121 passes through the three material guide plates 110 , and material rolls 122 are distributed in each compartment cavity 101 .

[0036] Optionally, a vibration motor is provided at the bottom of the three-dimensional silo 100, and the vibration motor drives the three-dimensional silo 100 to vibrate to assist the falling of the aggregate. The vibration motor does not run continuously, but runs intermittently or at a fixed time, such as vibrating for 10 seconds every 10 minutes, to prevent the aggregate from being blocked in the material port 111.

[0038] The transmission belt 220 is driven by a driving assembly (not shown), which may be a combination of a motor, a transmission gear and a chain.

[0039] The specific use principle of the utility model is as follows: during unloading, the aggregate enters the three-dimensional silo 100 from the high-position feed port, and the motor 130 drives the stirring rod 120 to rotate. The aggregate is stirred during the process, and the aggregate flows downward from the feed port 111. The aggregate slows down its falling speed through the cooperation of the guide plate 110 and the stirring rod 120, and prevents the separation of coarse and fine particles due to the large height difference of the feeding, and prevents segregation; the aggregate falls into the track 200 from the discharge port, and is transmitted through the conveyor belt 220. During the transmission, it is blocked by the block member 210, one is to prevent the aggregate from falling too fast due to the inclination angle of the material track 200, and the coarse and fine particles are mixed again during the transmission process, so that the coarseness and fineness of the aggregate are uniform.
