Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a fully automatic wheat turning spiral device. Background Technology

[0002] In the grain processing and brewing industry, wheat turning is a crucial step in processes such as malt preparation and wheat drying. Fully automated wheat turning spiral devices, with their advantages of mechanization and automation, are gradually replacing traditional manual wheat turning methods, becoming core equipment for improving production efficiency and reducing labor costs. This device uses the rotational motion of a spiral shaft to turn the material, reducing labor intensity to a certain extent compared to manual turning and providing equipment support for large-scale production.

[0003] Currently, most fully automatic wheat-turning spiral devices on the market adopt a fixed spiral shaft structure. The spiral shaft is installed on a fixed frame and rotates through a motor to complete the wheat-turning operation. The material is placed in a fixed feeding trough. When the spiral shaft rotates, it only relies on the agitation of its own blades to turn the material. In terms of ventilation, most devices only have simple ventilation openings and lack an effective air circulation structure. As for equipment maintenance, its internal components are usually fixedly connected, making it difficult to disassemble and clean quickly.

[0004] However, existing fully automatic wheat turning spiral devices have shortcomings. Due to the fixed position of the spiral shaft and the lack of a linkage displacement mechanism, uneven material turning is prone to occur during the turning process, especially in the corner areas of the material trough. Insufficient turning often leads to inconsistent fermentation or drying of the material, affecting product quality. At the same time, the ventilation structure of traditional devices cannot meet the strict oxygen supply requirements of specific processes such as malt germination, and the internal components are inconvenient to maintain. Once residual material accumulates, the cleaning process is time-consuming and labor-intensive, seriously affecting the operating efficiency and service life of the equipment. Therefore, a fully automatic wheat turning spiral device is proposed to solve the above problems. Utility Model Content

[0034] 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.

[0035] Reference Figures 1-3This utility model provides an embodiment of a fully automatic wheat-turning spiral device, including a material storage trough 1, which serves as the main material carrier. The material storage trough 1 is welded from 304 stainless steel plate, and its inner wall is polished, providing good corrosion resistance and material flowability. It is used to store the material to be turned. Fixed plates 3 are welded and fixedly connected to the top front and rear sides of the material storage trough 1. The fixed plates 3 are used to install guide rails 4 and racks 9, and provide a supporting foundation for the entire walking assembly. The top of the two fixed plates 3 is bolted to the guide rails 4. The bottom of the guide rails 4 is fixed to the fixed plates 3, and the top engages with sliders 10 to provide precise guidance for the movement of the walking assembly. Racks 9, made of alloy steel, are welded and fixedly connected inside the fixed plates 3. The racks 9 mesh with gears 8 to transmit walking power. The walking assembly, located on one side of the top of the material storage trough 1, is the core part for realizing the movement of the device. It consists of a frame 5, a drive motor 6, a rotating shaft 7, and gears 8. The frame 5 is welded from steel pipe, and the four corners are bolted to the sliders 10. The frame 5 is used to install the drive motor 6 and the turning component, and to move the entire working part above the material trough 1. The sliders 10 fixedly connected to the four corners of the frame 5 are sliding blocks that match the guide rail 4. They are equipped with ball bearings and form a rolling fit with the guide rail 4. The bottom is fixed to the frame 5 with bolts and can slide along the top of the guide rail 4 to ensure the smoothness and accuracy of the movement of the walking component. The drive motor 6 is installed on one side of the top of the frame 5. The drive motor 6 is located on the side of the turning component and is fixed to the top of the frame 5 with bolts to provide power to the walking component. The drive motor 6 is existing technology and will not be described in detail in this article. The output end of the drive motor 6 is fixedly connected to the rotating shaft 7 through a coupling. The outer walls of the two sides of the rotating shaft 7 are connected to the bottom of the frame 5 through bearings and can rotate freely at the bottom of the frame 5 to transmit the power of the drive motor 6. The two ends of the rotating shaft 7 are fixedly connected to the gears 8 through keys. The gears 8 are made of alloy steel and mesh with the rack 9. The rotational motion of the rotating shaft 7 is converted into the linear motion of the frame 5 through the transmission of the gears 8 and the rack 9.

[0036] The turning assembly is the key component for turning the material. It is arranged in an array on the frame 5 and includes a second drive motor 11 and a spiral turner 12. The second drive motor 11 is fixed to the other side of the frame 5 by bolts and is used to drive the spiral turner 12 to rotate. The second drive motor 11 is existing technology and will not be described in detail in this article. The spiral turner 12 is made of 304 stainless steel and consists of spiral blades and a central shaft. The spiral blades are located inside the material trough 1 and are connected to the output end of the second drive motor 11 through a coupling. When rotating, it can turn and convey the material. Support legs 2 are set at the four corners of the material trough 1. The top of the support legs 2 is connected to the bottom of the fixing plate 3 by welding. Anchor bolt holes are installed at the bottom to fix the device to the ground and ensure the stability of the equipment during operation.

[0037] Reference Figures 4-6 The bottom of the inner wall of the material storage trough 1 is milled to create multiple rectangular array-shaped ventilation slots 13. These slots are laser-cut with rounded edges to prevent scratching the material. The ventilation slots 13 provide an airflow channel between the inside of the material storage trough 1 and the air inlet assembly, allowing fresh air to smoothly enter and meet the oxygen requirements of malt germination and other processes. They also help to remove moisture, preventing localized dampness and mold growth. The air inlet assembly at the bottom of the material storage trough 1 is a key structure for providing fresh oxygen to the interior of the trough 1. The air inlet assembly uses a fixed frame 14 as its main frame. 4 is made of 304 stainless steel plate, bent and welded, with an overall rectangular structure. The top of the fixed frame 14 is fixedly connected to the bottom of the material storage tank 1 by bolts, which is used to support and protect the components such as the air intake fan 15 inside the air intake assembly, and at the same time provide a sliding track for the partition plate 16. Multiple air intake fans 15 are arranged in an array and fixedly connected to the bottom of the fixed frame 14 by bolts. The air intake fans 15 are axial flow fans. The air intake fans 15 are evenly distributed in the fixed frame 14. The motor drives the impeller to rotate at high speed, which draws in fresh air from the outside and pressurizes it, so that it enters the material storage tank 1 through the ventilation groove 13, ensuring that the material in the material storage tank 1 is in good ventilation. Regarding the environment, the intake fan 15 is existing technology and will not be described in detail here. The fixed frame 14 has a guide groove inside, forming a sliding fit with the partition plate 16. The partition plate 16 is made of 304 stainless steel and is used to filter impurities in the air, preventing dust and foreign objects from entering the material storage tank 1 and contaminating the material. Symmetrical handles 17 are welded to the side walls of the partition plate 16. The surface of the handles 17 is treated with an anti-slip coating to facilitate the application of force by the operator to pull the partition plate 16. Multiple limit balls 20 arranged in an array are set on the left and right sides inside the partition plate 16. The limit balls 20 are made of bearing steel. Each limit ball... The side wall of the partition plate 16 is fixedly connected to the limiting plate 19 by welding. The outer wall of the limiting plate 19 and the guide groove inside the partition plate 16 form a sliding fit to guide the displacement of the limiting ball 20 and transmit the force of the limiting spring 18. The limiting plate 19 is provided with a limiting spring 18 on its side. The limiting spring 18 is made of spring steel. One end of the limiting spring 18 is welded to the spring seat preset inside the partition plate 16, and the other end is welded to the side wall of the limiting plate 19 to provide a reset elastic force for the limiting ball 20, so that the limiting ball 20 can quickly be inserted into the positioning groove of the inner wall of the fixed frame 14, so as to realize the stable installation of the partition plate 16 and prevent it from being displaced during the air intake process.

[0038] Working principle: When using this fully automatic wheat turning spiral device, the operator pours the material into the material trough 1 and then starts the equipment. At this time, the drive motor 6 drives the rotating shaft 7 to rotate through the drive wheel and belt. The rotation of the rotating shaft 7 drives the gears 8 on both sides to rotate as well. With the cooperation of the rack 9, the rotation of the gears 8 drives the entire frame 5 to move, so that the sliders 10 on both sides of the frame 5 slide on the surface of the guide rail 4, so that the device can move smoothly on the walking track of the material trough 1. At the same time, the spiral wheat turner 12 also moves synchronously. While the spiral wheat turner 12 moves, it is also driven by the drive motor 11 to rotate, thereby achieving the effect of fully turning the material in different areas inside the material trough 1.

[0039] While the malt is being turned, multiple intake fans 15 at the bottom of the feeding trough 1 are also working simultaneously, drawing fresh air from the outside into the feeding trough 1. The fresh air enters the feeding trough 1 through the ventilation groove 13 at the bottom of the feeding trough 1, thereby meeting the oxygen requirements for malt germination and preventing local dampness and mold growth. When performing routine maintenance, the operator can pull the partition plate 16 out of the fixed frame 14 using the handle 17, then clean the surface of the partition plate 16. After cleaning, the partition plate 16 is reinserted into the fixed frame 14. At this time, the limiting springs 18 on both sides of the partition plate 16 push the limiting plate 19 to move, thereby causing the limiting ball 20 to engage in the positioning groove on the inner wall of the fixed frame 14, thus limiting the partition plate 16 and achieving the effect of quickly cleaning the partition plate 16.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
