[0001] The utility model relates to the technical field of white liquor koji-making production equipment, and particularly relates to a linear distribution and conveying device. Background Art

[0002] During the production process of brewing koji, wheat needs to be crushed. During the crushing process of wheat, a certain amount of fine powder dust will be generated. In the prior art, in order to recycle the generated fine powder dust, it is generally recycled through a dust removal system and then conveyed into a mixing conveyor in the koji-making production line for utilization. However, in actual production, there will be situations where different floors and multiple flour mills work simultaneously. When the amount of generated dust is large, if the recycled fine powder is conveyed into a certain mixing conveyor, it will have a great impact on the addition ratio of the mother koji in the koji-making process and affect the quality of the koji embryos. Therefore, it is necessary to distribute the recycled powder. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiment 1:

[0020] As Figures 1 to 4 shown, a linear distribution and conveying equipment includes a powder conveyor 1. The powder conveyor 1 can be a belt conveyor or a screw conveyor. The feeding port of the powder conveyor 1 is connected to the dust recovery system through a pipeline, and the conveying process of the powder conveyor 1 is a closed conveying, reducing the impact on the environment.

[0021] The discharge port 101 of the powder conveyor 1 is provided with a distribution hopper 2. The distribution hopper 2 is sleeved at the lower end of the discharge port 101 of the powder conveyor 1. Specifically, as Figure 4 shown, two groups of rotating shafts 3 are provided on the inner wall of the distribution hopper 2. One end of the rotating shaft 3 is fixedly connected to the distribution hopper 2, and the other end is rotatably installed on the side wall of the discharge port 101 of the powder conveyor 1 through a bearing. The bearing is fixed on the outer side of the discharge port 101 or the bearing installation hole on the side wall of the discharge port 101. A servo motor 4 is provided on the outer side of the discharge port 101 of the powder conveyor 1. The output shaft of the servo motor 4 is connected to one group of the rotating shafts 3 through a transmission mechanism 5. In this embodiment, the transmission mechanism 5 includes a driving wheel 501 provided on the output shaft of the servo motor 4. A driven wheel 502 is provided on one group of the rotating shafts 3. A transmission belt 503 is provided between the driving wheel 501 and the driven wheel 502. The rotation of the rotating shaft 3 is driven through belt transmission. In actual use, the transmission mechanism 5 can also be a gear transmission, a chain transmission, etc. Preferably, the distribution hopper 2 is a conical hopper with a larger upper part and a smaller lower part, which is convenient for transporting the powder to the corresponding conveying pipeline 7.

[0022] A distribution pipe mechanism is provided below the distribution hopper 2. The distribution pipe mechanism includes a material collecting hopper 6. A plurality of conveying pipelines 7 are provided at the lower end of the material collecting hopper 6. The conveying pipelines 7 are arranged in a column at the lower end of the material collecting hopper 6. The conveying pipelines 7 transport the powder into the mixing equipment of the koji-making production lines on different floors. For example, in this embodiment, four groups of conveying pipelines 7 are provided, which are respectively connected to the mixing equipment on the corresponding first floor, second floor, third floor and fourth floor.

[0023] During specific use, the feed port of the powder conveyor 1 is connected to the dust recovery system through a pipeline. The powder conveyor 1 transports the recovered powder to the distribution hopper 2. The servo motor 4 drives the rotating shaft 3 to rotate through the transmission mechanism 5, driving the distribution hopper 2 to swing reciprocally. For example, when the distribution hopper 2 swings above a certain conveying pipeline 7, it pauses for 1 min to make the powder fall, and then continues to swing above the adjacent conveying pipeline 7 and pauses for 1 min to make the powder fall. Running according to this program, the powder is discharged evenly, so that the powder enters each conveying pipeline 7 evenly, and the powder is evenly transported into the mixing equipment on each floor. Or, if it is only necessary to transport the powder into the mixing equipment of the koji-making production line on a certain floor, the distribution hopper 2 is swung and adjusted above the corresponding conveying pipeline 7, and then the servo motor 4 stops starting to supply materials to the mixing equipment of the koji-making production line on a certain floor.

[0024] Embodiment 2:

[0025] Different from Embodiment 1, as Figure 1As shown, a dust-proof cover 8 is provided between the upper end of the material collecting hopper 6 and the discharge port 101 of the powder conveyor 1, and the distribution hopper 2 is arranged inside the dust-proof cover 8. The dust-proof cover 8 is set as a flexible dust-proof cover, for example, it can be made of silica gel material. By setting the dust-proof cover 8, the diffusion of dust during material dropping can be avoided.

[0026] Preferably, a breathing pipe 9 is provided at the top of the dust-proof cover 8. The lower end of the breathing pipe 9 is communicated with the inside of the dust-proof cover 8, and the upper end is communicated with the powder conveyor 1.

[0027] During the process of the distribution hopper 2 swinging for material distribution, the air in the area of the dust-proof cover 8 will flow, and the dust in the conveying pipeline 7 will also rise through the pipeline and gather in the dust-proof cover 8. At this time, the air pressure in the dust-proof cover 8 is slightly positive. By setting the breathing pipe 9, the slightly positive pressure in the dust-proof cover 8 is released, and at the same time, the dust is carried into the powder conveyor 1 to complete the self-circulation process.
