Description

Technical Field

[0001] This utility model relates to the field of liquor brewing technology, and in particular to a turning and rake device. Background Technology

[0002] In the brewing process of Maotai-flavor baijiu, the spreading and cooling process is a unique and crucial step among many complex processes. The spreading and cooling process includes, in sequence, removing the mash from the still, spreading it evenly on the ground, creating and breaking up the ridges, kneading, turning and rakeing, adding the final distillate, adding yeast powder, turning and mixing again, cooling, and finally, piling for fermentation. In the traditional process, workers use a crane and shovels to evenly spread the mash on the ground, barefoot, creating and breaking up the ridges, manually kneading and turning the mash using specialized tools, then manually adding the final distillate, followed by manually adding yeast powder, constantly turning and mixing, repeating this process multiple times, and finally cooling to complete the spreading and yeast addition process.

[0003] In the aforementioned traditional process, the temperature of the mash immediately after being removed from the still is quite high, which can easily burn workers, resulting in high labor intensity. Furthermore, it is greatly affected by human factors, leading to issues such as uneven mash formation, uneven application of yeast powder, insufficient mixing, and uneven or inadequate heat dissipation. These problems directly impact subsequent processes, ultimately affecting the yield and quality of the alcohol. Currently, the industry has introduced some dispersing and turning devices to replace manual spreading and cooling operations, but incomplete material turning still exists. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] In the description of the embodiments of this utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more.

[0040] The following combination Figures 1-6 This invention describes the turning and rake device provided by this utility model.

[0041] like Figure 1 and Figure 2 As shown, the turning and rake device provided in this embodiment of the present invention includes a frame 1, a turning and rake mechanism 2, and a tension mechanism 3. The turning and rake mechanism 2 is connected to the frame 1 and can swing up and down relative to the frame 1. The tension mechanism 3 is provided between the upper end of the turning and rake mechanism 2 and the frame 1, and the lower end of the turning and rake mechanism 2 contacts the working surface under the action of the tension mechanism 3.

[0042] When the turning and rake device is in operation, the frame 1 moves relative to the material to be turned and raked. For example, the frame 1 moves in a specific direction to drive the turning and rake mechanism 2 to turn and rake the material laid on the ground. Alternatively, the frame 1 remains stationary, and the material is conveyed to the area below the turning and rake mechanism 2 via a conveyor chain, allowing the turning and rake mechanism 2 to turn and rake the material on the chain. The turning and rake mechanism 2 is located at one end of the frame 1 relative to the direction of material movement. The working surface refers to the ground, the upper surface of the conveyor chain, or other surfaces used for laying materials.

[0043] During the turning process, the turning mechanism 2 can swing up and down relative to the frame 1 as the working surface rises and falls. During the swinging process of the turning mechanism 2 relative to the frame 1, the tension mechanism 3 applies a force towards the working surface to the turning mechanism 2, so that the lower end of the turning mechanism 2 always remains in contact with the working surface.

[0044] When the rake reaches the concave side of the working surface, the rake mechanism 2 swings downward relative to the frame 1, releasing part of the tension in the tension mechanism 3. When the rake reaches the convex side of the working surface, the rake mechanism 2 swings upward relative to the frame 1, increasing the tension in the tension mechanism 3.

[0045] The turning and rake device provided by this utility model connects the turning and rake mechanism 2 to the frame 1 and allows the turning and rake mechanism 2 to swing up and down relative to the frame 1. A tension mechanism 3 is set between the upper end of the turning and rake mechanism 2 and the frame 1. Compared with the traditional method of fixing the turning and rake mechanism in the cooling process of liquor and breaking up and rakeing at a fixed point or height, the lower end of the turning and rake mechanism 2 of the present utility model can always keep in contact with the working surface under the action of the tension mechanism 3. It can adaptively adjust the height of the turning and rake mechanism 2 according to the uneven working surface, avoid incomplete turning of the mash and rigid impact between the device and the working surface, improve the turning and rakeing efficiency, reduce the intensity of manual labor, and ensure equipment safety.

[0046] In this embodiment of the utility model, the turning and rake mechanism 2 includes a mounting frame 21 and a turning and rake component 22. The turning and rake component 22 is connected to the mounting frame 21, and the tension mechanism 3 is disposed between the upper end of the mounting frame 21 and the frame 1.

[0047] Optionally, the turning rake 22 is rotatably connected to the mounting frame 21, allowing the turning rake 22 to rotate relative to the mounting frame 21 during the turning process. Specifically, as shown... Figure 1 As shown, the turning and rake device also includes a first connecting member 4. The lower end of the mounting frame 21 is connected to the frame 1 through the first connecting member 4, so that the turning and rake mechanism 2 can swing up and down relative to the frame 1 around the connection point between the first connecting member 4 and the frame 1.

[0048] See Figure 2The mounting frame 21 includes a first connecting plate 211 and a second connecting plate 212 arranged opposite to each other. One end of the turning rake 22 is rotatably connected to the first connecting plate 211, and the other end of the turning rake 22 is rotatably connected to the second connecting plate 212. The first connecting plate 211 and the second connecting plate 212 are respectively connected to the frame 1 and can swing up and down relative to the frame 1.

[0049] It is understood that the first connecting plate 211 and the second connecting plate 212 are arranged vertically and are parallel to each other at both ends of the turning axis of the rake 22. The rake part of the rake 22 is located between the first connecting plate 211 and the second connecting plate 212.

[0050] Furthermore, the mounting bracket 21 also includes a connecting rod 213, which is fixedly connected between the first connecting plate 211 and the second connecting plate 212. There can be multiple connecting rods 213, which are arranged parallel to each other.

[0051] The rake 22 is rotatably connected to the lower end of the first connecting plate 211 and the second connecting plate 212, and a tension mechanism 3 is provided between the upper end of at least one of the first connecting plate 211 and the second connecting plate 212 and the frame 1.

[0052] Specifically, a tension mechanism 3 can be installed between the first connecting plate 211 and the frame 1; or a tension mechanism 3 can be installed between the second connecting plate 212 and the frame 1. Alternatively, tension mechanisms 3 can be installed between both the first connecting plate 211 and the frame 1 and between the second connecting plate 212 and the frame 1. By installing two tension mechanisms 3, forces can be applied simultaneously to both ends of the turning rake 22 toward the mounting surface, making the turning rake mechanism 2 more stably fit the working surface and ensuring the turning effect.

[0053] like Figure 5 and Figure 6 As shown in this embodiment of the invention, the turning and rake component 22 includes a roller 221 and a plurality of turning and rake teeth 222. The plurality of turning and rake teeth 222 are fixed to the roller 221, and both ends of the roller 221 are rotatably connected to the mounting frame 21. Specifically, one end of the roller 221 is rotatably connected to the first connecting plate 211, and the other end of the roller 221 is rotatably connected to the second connecting plate 212. The plurality of turning and rake teeth 222 are evenly distributed on the outer side of the roller 221.

[0054] Specifically, the lower ends of the first connecting plate 211 and the second connecting plate 212 are respectively connected to the frame 1 via a first connecting member 4, allowing the turning and rake mechanism 2 to swing up and down relative to the frame 1 around the line connecting the connection points of the two first connecting members 4 and the frame 1. One first connecting member 4 has its two ends rotatably connected to the first connecting plate 211 and the frame 1, and the other first connecting member 4 has its two ends rotatably connected to the second connecting plate 212 and the frame 1. The line connecting the connection points of the two first connecting members 4 and the frame 1 is parallel to the roller 221.

[0055] Furthermore, the frame 1 is provided with a connecting part 12, which is located at one end of the frame 1 and extends toward the ground. One end of the first connecting member 4 is rotatably connected to the turning and rake mechanism 2, and the other end of the first connecting member 4 is rotatably connected to the connecting part 12.

[0056] like Figure 3 and Figure 4 As shown in the embodiment of this utility model, the tension mechanism 3 includes a bushing 31, a connecting shaft 32, and an elastic element 33. The bushing 31 is rotatably connected to the frame 1 on both sides of its axial direction. One end of the connecting shaft 32 is rotatably connected to the turning and rake mechanism 2, and the other end of the connecting shaft 32 is movably inserted through the bushing 31. The elastic element 33 is sleeved on the connecting shaft 32 and pressed between the turning and rake mechanism 2 and the bushing 31.

[0057] In this embodiment, the tension mechanism 3 is a spring tension mechanism, wherein the elastic element 33 can be a tension spring, or a compression spring, a bellows spring, or other springs that can provide tension; this embodiment does not limit this. Of course, the tension mechanism 3 can also be a gas tension mechanism formed by the cooperation of a cylinder and a piston rod; this embodiment does not limit this.

[0058] Specifically, the tension mechanism 3 further includes a second connecting member 37, one end of the connecting shaft 32 is fixed to the second connecting member 37, and is rotatably connected to the turning mechanism 2 through the second connecting member 37. Optionally, the upper ends of the first connecting plate 211 and the second connecting plate 212 are both connected to the frame 1 through a tension mechanism 3, and correspondingly, the upper ends of the first connecting plate 211 and the second connecting plate 212 are rotatably connected to a second connecting member 37.

[0059] A connecting seat 11 is provided on the frame 1. The bushing 31 includes a sleeve body and a rotating shaft. The other end of the connecting shaft 32 is movably inserted through the sleeve body. Rotating shafts are provided on both sides of the sleeve body. The bushing 31 is rotatably connected to the connecting seat 11 through the rotating shafts on both sides. When the turning mechanism 2 swings up and down relative to the frame 1, the connecting shaft 32 rotates relative to the connecting seat 11 through the bushing 31. The elastic element 33 is pressed between the turning mechanism 2 and the bushing 31. The turning mechanism 2 remains in contact with the working surface under the tension of the elastic element 33. When the turning mechanism 2 swings upward, the tension of the elastic element 33 increases; when the turning mechanism 2 swings downward, the tension of the elastic element 33 is partially released.

[0060] In this embodiment of the invention, the tension mechanism 3 further includes an adjusting member 34, which is disposed on the connecting shaft 32 and whose position on the connecting shaft 32 is adjustable. The elastic member 33 is pressed between the adjusting member 34 and the bushing 31. The turning and rake device can adjust the tension of the elastic member 33 by adjusting the position of the adjusting member 34 on the connecting shaft 32, thereby adjusting the amount of swing of the turning and rake mechanism 2 relative to the frame 1 to adapt to working surfaces with different undulations.

[0061] Optionally, the adjusting element 34 is an adjusting nut, which is threadedly connected to the connecting shaft 32 to facilitate the adjustment of the position of the adjusting element 34. The adjusting element 34 can also be other types of structural components, such as a stop pin. Furthermore, the adjusting element 34 includes two adjusting nuts, and tightening the two adjusting nuts can form an interlocking effect, effectively preventing the adjusting element 34 from automatically loosening and ensuring the tension stability of the elastic element 33.

[0062] Furthermore, such as Figure 4 and Figure 5 As shown, the tension mechanism 3 also includes a limiting member 35, which is disposed on the connecting shaft 32 and located on the side of the bushing 31 away from the elastic member 33. The limiting member 35 and the bushing 31 are engaged in an axial upper limit fit between the limiting member 35 and the bushing 31.

[0063] Optionally, the limiting member 35 is a nut, which is threadedly connected to the connecting shaft 32 to facilitate the connection and installation of the connecting shaft 32 and the bushing 31. Further, the limiting member 35 includes two nuts; tightening the two nuts creates an interlocking effect, effectively preventing the limiting member 35 from automatically loosening and ensuring a reliable connection between the tension mechanism 3 and the frame 1. Further, the tension mechanism 3 also includes a washer 36, which is disposed between the limiting member 35 and the elastic member 33 to prevent the limiting member 35 from loosening.

[0064] like Figure 5 and Figure 6As shown, in some embodiments of this utility model, the turning and rake component 22 includes a roller 221 and a plurality of turning and rake teeth 222. The plurality of turning and rake teeth 222 are fixed to the roller 221, and the two ends of the roller 221 are respectively rotatably connected to the mounting frame 21. The turning and rake mechanism 2 also includes a first traveling wheel 23, and the two ends of the roller 221 are respectively rotatably connected to the first traveling wheel 23. The maximum outer diameter of the turning and rake component 22 is smaller than the outer diameter of the first traveling wheel 23.

[0065] It is understandable that the lower end of the turning mechanism 2 corresponds to the first traveling wheel 23. When the turning device is performing the turning operation, the turning mechanism 2 contacts the working surface through the first traveling wheel 23, and there is a gap between the turning teeth 222 on the turning component 22 and the working surface. This can prevent the turning teeth 222 from colliding with the working surface and protect the turning component 22.

[0066] The first traveling wheel 23 of the turning and rake device in this embodiment of the utility model can always maintain contact with the working surface under the action of the tension mechanism 3. Even if there are undulations in the working surface, it can ensure that there is a constant gap between the turning and rake component 22 and the working surface, thus ensuring the turning and rake effect.

[0067] like Figure 1 As shown, the turning and rake device provided in this embodiment of the present invention also includes second traveling wheels 13. Multiple second traveling wheels 13 are provided at the bottom of the frame 1, and the height of the second traveling wheels 13 relative to the working surface is higher than that of the first traveling wheels 23. During operation, the material is typically laid below the turning and rake device. The first traveling wheels 23 are in contact with the working surface, and the second traveling wheels 13 are higher than the first traveling wheels 23, allowing the turning and rake device to travel on equipment or tracks higher than the working surface via the second traveling wheels 13, while simultaneously traveling on the working surface via the first traveling wheels 23.

[0068] It should be noted that the turning and rake device may not be equipped with the second traveling wheel 13. The frame 1 can be installed on other traveling mechanisms and driven to move on the equipment or track by other traveling mechanisms.

[0069] like Figure 5 and Figure 6 As shown, the turning device provided in this embodiment of the present invention also includes a driving component, which is disposed on the mounting frame 21 and connected to the roller 221 for driving the roller 221 to rotate relative to the mounting frame 21.

[0070] Specifically, the drive component is mounted on either the first connecting plate 211 or the second connecting plate 212. Optionally, the drive component includes a geared motor 241 and a chain drive assembly 242. The geared motor 241 is fixed to the mounting bracket 21 and connected to the roller 221 via the chain drive assembly 242. The geared motor 241 can be replaced with a hydraulic or pneumatic drive component that provides rotational drive, and the chain drive assembly 242 can be replaced with a belt drive assembly or other transmission assembly. In this embodiment, the drive component drives the turning and raking component 22 to rotate, which further improves the material-dispersing and turning effect of the turning and raking component 22.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
