Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermented grains spreading and drying technology, and in particular to an automatic feeding and mixing machine for fermented grains spreading and drying. Background Technology
[0002] Distillers' grains, a byproduct of the brewing process, are widely used in animal feed and fertilizer. Rich in protein, cellulose, and minerals, they have high utilization value in agriculture and animal husbandry. To improve the drying efficiency of distillers' grains, a spreading machine is typically used to evenly spread them out, allowing them to dry effectively under sunlight or other heating equipment. During the brewing process, adding starter culture promotes fermentation and flavor development in the grains. A starter culture-mixing distillers' grains spreading machine enables automated processing and spreading of the grains, improving production efficiency.
[0003] Existing koji-mixing and lees-spreading machines generally employ mechanical structures for spreading and preliminary drying of the lees. Most machines use conveying mechanisms and spreading devices to evenly distribute the koji-mixed lees within the spreading area, controlling the drying effect by adjusting the spreading thickness or the moving speed. These machines have achieved a certain level of automation and processing capacity, meeting the basic needs of routine production. However, in actual operation, the moisture content and texture of different batches of lees vary, making it difficult for existing spreading equipment to dynamically adapt to the spreading thickness. This leads to localized accumulation or overly loose distribution of the lees during spreading, affecting drying uniformity and fermentation results. Therefore, an automatic feeding koji-mixing and lees-spreading machine is proposed to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-2This utility model provides an embodiment of an automatic feeding, mixing, and drying machine for distiller's grains, comprising a conveyor 1, a feeder 2 on one side of the conveyor 1 for stably conveying raw materials to the conveyor 1 to ensure continuity and uniformity, a grain conveying box 3 on the top of the conveyor 1 to further improve the working efficiency of the equipment and avoid production fluctuations caused by uneven or unstable raw material input, a leveling mechanism on the conveyor 1, and a mixing mechanism on the top of the conveyor 1; the leveling mechanism includes a leveling plate 9, a fixed frame 4 fixedly connected to the top of the conveyor 1, a sliding rod 5 slidably connected inside the fixed frame 4, and a limit plate 7 fixedly connected to the side wall of the sliding rod 5. A fixed plate 6 is fixedly connected to the side wall of the slide rod 5, and a spring 8 is sleeved on the outside of the slide rod 5. A paving plate 9 is fixedly connected to the bottom of the slide rod 5. During operation, the paving plate 9 can flexibly adapt to different thicknesses of lees and adjust the paving effect. Multiple guide grooves 10 are opened inside the paving plate 9. The guide grooves 10 are evenly distributed in a straight line. One end of the spring 8 is fixedly connected to the bottom of the fixed frame 4, and the other end of the spring 8 is fixedly connected to the side wall of the fixed plate 6. In the natural state of the spring 8, the limiting plate 7 is in contact with the top of the fixed frame 4. When the paving plate 9 comes into contact with the lees, it automatically adjusts the pressure to achieve the effect of evenly paving the surface of the lees and avoid local accumulation or excessive looseness of the lees.
[0031] Reference Figures 3-4 The mixing mechanism includes a rotating shaft 12 and a hook plate 16. The rotating shaft 12 is rotatably connected inside the conveyor 1 to ensure the stability and efficiency of the mixing process. The rotation of the shaft 12 can drive the hook plate 16 to achieve the required mixing effect. The hook plate 16 is fixedly connected to the side wall of the shaft 12 to enhance the uniformity of the mixing process and avoid uneven mixing of the lees. A connecting rod 17 is fixedly connected between the hook plates 16 to make the hybrid power transmission more uniform. A drive assembly is provided on the side wall of the conveyor 1. The drive assembly includes a motor 13, a sprocket 14 and a chain 15. One end of the shaft 12 passes through the side wall of the conveyor 1 and extends to the outside. The sprocket 14 is fixedly connected to the end of the shaft 12 that passes through the conveyor 1. The two sprockets 14 are driven by the chain 15. The motor 13 is fixedly connected to the side wall of the conveyor 1. The output end of the motor 13 is fixedly connected to one end of the shaft 12 on one side. A baffle 11 is fixedly connected to the top of the conveyor 1 to effectively prevent the lees from splashing out due to vibration or improper operation during the mixing process and to keep the operating environment clean. The baffle 11 is set on both sides of the mixing mechanism.
[0032] Working principle: When the equipment is in operation, the feeder 2 sends the lees into the conveyor 1, and the lees are transported by the conveyor belt inside. During the transport process, the spreading plate 9 spreads the lees evenly and can adaptively adjust its height according to the thickness of the lees pile. The spreading plate 9 slides inside the fixed frame 4 through the slide bar 5, and the spring 8 deforms to maintain the stability of the spreading plate 9. After the lees are spread, when they pass the bottom of the grain conveying box 3, the grain stored inside the grain conveying box 3 will fall onto the top of the lees. At this time, the motor 13 drives the shaft 12 connected to it to rotate, and through the cooperation of the sprocket 14 and the chain 15, drives the shaft 12 on the other side to rotate. Then, the hook plate 16 mixes the lees and grains, and the spreading mechanism at the rear levels them again to prevent the pile from being too high and slipping out of the conveyor 1.
