Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquor drying equipment, and in particular to a deflection drying device and a deflection drying system for breaking up stems. Background Technology
[0002] In the brewing process of Maotai-flavor baijiu, the spreading and cooling process plays a crucial role. The traditional spreading and cooling process is quite complex, mainly involving steps such as removing the mash from the still, spreading it evenly on the ground, creating and breaking up ridges, kneading, turning and rakeing, adding the final distillate, adding yeast powder, turning and mixing again, cooling, and finally, piling for fermentation. Specifically, workers use overhead cranes and shovels to evenly spread the mash on the ground, creating and breaking up ridges barefoot. They then use specialized tools to knead and rake the mash, followed by adding the final distillate and yeast powder, mixing continuously. After multiple turnings, the mash cools naturally or is cooled more quickly using a blower, completing the cooling and yeast-adding process. However, because the mash is very hot when it is first removed from the still, the traditional spreading and yeast-adding process is difficult to operate, easily causing burns to workers, and is physically demanding. In addition, manual operation is greatly affected by human factors, such as uneven breaking of the mash, uneven distribution of the distillate and yeast powder, insufficient mixing, and uneven heat dissipation. These factors can directly affect the implementation of subsequent processes and ultimately affect the yield and quality of the liquor.
[0003] To address the shortcomings of manual spreading and cooling processes, numerous mechanical devices have been developed to replace manual labor in this operation. For example, conveyor chains are used to spread the mash evenly, and toothed dispersing mechanisms are designed for turning and rake operations. However, existing machinery cannot perform the tasks of removing and breaking up the stalks in the traditional process. Furthermore, the added yeast powder often adheres to the upper layer of the mash, and the dispersing mechanism cannot effectively turn and rake the bottom layer of material. This results in the bottom layer material not being fully mixed with the yeast powder, and simultaneous cooling and moisture evaporation cannot be achieved. Utility Model Content

[0011] The device for lifting and breaking branches in a drying rack according to this utility model further includes two lifting mechanisms corresponding to the two branch-breaking mechanisms. The two lifting mechanisms are spaced apart on the frame along a first direction. Each lifting mechanism includes a second drive assembly and a lifting bracket. The first side of the lifting bracket is rotatably connected to the frame, and the second side of the lifting bracket is located inside the corresponding branch-breaking component to drive the corresponding branch-breaking component to switch between a working position and a storage position.

[0012] According to the offset drying and stalk breaking device provided by this utility model, the second driving component includes a second driving motor, a fifth connecting rod and a sixth connecting rod.

During both splitting and splitting, the first drive assembly drives the rotating shaft to periodically swing within a set angle range, thereby driving the first connecting rod to periodically swing within the set angle range and causing the splitting components to perform periodic splitting or splitting actions. This increases the contact area between the fermented mash and air, improves spreading efficiency, and reduces manual labor intensity.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0034] The following is combined Figures 1 to 7 This invention describes the device and system for splitting stems during the drying process of a plant.
[0035] See Figures 1 to 4 As shown in the figure, the eccentric stalk breaking device provided in this embodiment of the utility model includes: a frame 100 and two stalk breaking mechanisms 200.
[0036] Two chaff-breaking mechanisms 200 are spaced apart on the frame 100 along a first direction. Each chaff-breaking mechanism 200 includes a first drive assembly 210, a rotating shaft 220, and multiple chaff-breaking units 230. The rotating shaft 220 is rotatably connected to the frame 100. The multiple chaff-breaking units 230 are spaced apart on the rotating shaft 220 along a second direction. Each chaff-breaking unit 230 includes a first connecting rod 231 and a chaff-breaking component 232. The first end of the first connecting rod 231 is connected to the rotating shaft 220, and the second end of the first connecting rod 231 is hinged to the first end of the chaff-breaking component 232. The second end of the chaff-breaking component 232 is provided with shovel teeth 233. The first drive assembly 210 is drively connected to the rotating shaft 220 to drive the rotating shaft 220 to oscillate periodically within a set angle range.
[0037] The plurality of breaking members 232 in one breaking mechanism 200 are arranged alternately with the plurality of breaking members 232 in another breaking mechanism 200.
[0038] It should be noted that, in this embodiment, "first direction" and "second direction" both refer to... Figure 2The arrow directions shown can be interpreted as follows: the first direction can be considered the running direction of the frame 100, and the second direction can be considered the width direction of the frame 100. Furthermore, either of the two chipping mechanisms 200 can function as either a chipping mechanism or a chipping mechanism. For example, when the frame 100 moves along the positive direction of the first direction, the chipping mechanism 200 located at the front can function as a chipping mechanism, and the chipping mechanism 200 located at the rear can function as a chipping mechanism; when the frame 100 moves along the negative direction of the first direction, the chipping mechanism 200 located at the rear can function as a chipping mechanism, and the chipping mechanism 200 located at the front can function as a chipping mechanism.
[0039] "Removing the stalks from the fermented mash" can be understood as using a stalk-removing mechanism to apply a shoveling action to the fermented mash spread flat in the trough 400, forming "stalks" with a set spacing. Correspondingly, "breaking the stalks from the fermented mash" can be understood as using a shoveling action to apply a shoveling action to the "stalks" using a stalk-breaking mechanism, driving the "stalks" to loosen.
[0040] The eccentric spreading and splitting device provided by this utility model has two splitting mechanisms 200 spaced apart along a first direction on the frame 100. During operation, the front splitting mechanism 200 can be used to split the stalks. Since the splitting components 232 in the two splitting mechanisms 200 are staggered, the rear splitting mechanism 200 can be used to split the stalks after splitting. During splitting and splitting, the first drive assembly 210 drives the rotating shaft 220 to swing periodically within a set angle range, thereby driving the first connecting rod 231 to swing periodically within the set angle range, and driving the splitting components 232 to perform periodic splitting or splitting actions. This can increase the contact area between the mash and the air, improve the spreading and drying efficiency, and reduce the intensity of manual labor.
[0041] Specifically, the utility model provides a device for splitting and breaking branches when drying on a side surface, which includes a frame 100 and two branch-breaking mechanisms 200.
[0042] The frame 100 provides mounting positions for the two crushing mechanisms 200 and other necessary components, and can be configured to be movably set in the feed trough 400, thereby driving the two crushing mechanisms 200 and other necessary components to move along the length of the feed trough 400 via the frame 100.
[0043] The stalk-removing and breaking mechanism 200 is used to automatically remove or break the stalks of the mash located in the feed trough 400, allowing the mash to fully contact with air and improving the spreading efficiency during the stalk-removing and breaking process. The stalk-removing and breaking mechanism 200 includes a first drive assembly 210, a rotating shaft 220, and multiple stalk-removing and breaking units 230. The rotating shaft 220 is rotatably connected to the frame 100, and the first drive assembly 210 is drively connected to the rotating shaft 220 to drive the rotating shaft 220 to periodically oscillate within a set angle range, thereby driving the multiple stalk-removing and breaking units 230 to apply a shoveling action to the mash, realizing stalk removal or breaking. The number of stalk-removing and breaking units 230 can be set according to actual needs, as long as it can cover all the material in the feed trough 400, and there is no limitation on this.
[0044] The crushing unit 230 includes a first connecting rod 231 and a crushing component 232. The first end of the first connecting rod 231 is connected to a rotating shaft 220, and the second end of the first connecting rod 231 is hinged to the first end of the crushing component 232. The second end of the crushing component 232 is provided with shovel teeth 233. When the rotating shaft 220 oscillates periodically within a set angle range, it can drive the first connecting rod 231 to oscillate synchronously, thereby driving the shovel teeth 233 to perform a shoveling action. Since the end of the shovel teeth 233 is supported by the wall of the mash or trough 400 during shoveling, no additional connecting rod is needed to support the crushing component 232.
[0045] The first drive assembly 210 can be implemented in various ways known in the prior art. For example, a motor drives a linkage mechanism to move, and the linkage mechanism drives the rotating shaft 220 to rotate periodically within a certain angle range; or the motor is directly connected to the rotating shaft 220 for transmission, controlling the output shaft of the motor to reciprocate within a certain angle range and driving the rotating shaft 220 to rotate periodically within a certain angle range.
[0046] Of course, the first drive component 210 may also employ other methods known in the prior art, and there is no limitation thereto.
[0047] See Figures 1 to 4 As shown in the example, in this embodiment, both rotating shafts 220 are hexagonal rotating shafts 220 (with a regular hexagonal cross-section). Bearing seats 110 are provided on both sides of the frame 100, with their ends rotatably connected to the sides of the frame 100 corresponding to the bearing seats 110. Five crushing units 230 are spaced apart on one rotating shaft 220, and six crushing units 230 are spaced apart on the other rotating shaft 220. All crushing units 230 can cover all transverse areas within the feed trough 400.
[0048] See Figure 4 and Figure 5As shown, according to some embodiments of the present invention, the first drive assembly 210 includes a first drive motor 211, a second connecting rod 212, a third connecting rod 213, and a fourth connecting rod 214. The first drive motor 211 is mounted on the frame 100. The first end of the second connecting rod 212 is connected to the output shaft of the first drive motor 211. The second end of the second connecting rod 212 is hinged to the first end of the third connecting rod 213. The second end of the third connecting rod 213 is hinged to the first end of the fourth connecting rod 214. The second end of the fourth connecting rod 214 is connected to the rotating shaft 220.
[0049] By configuring the first drive assembly 210 as a linkage mechanism including a first drive motor 211, a second link 212, a third link 213, and a fourth link 214, the periodic oscillation of the rotating shaft 220 can be driven by the transmission mechanism of the linkage mechanism, which simplifies the complexity of the control system and improves the stability and efficiency of operation. In addition, the motion transmission of the linkage mechanism has high reliability and durability, and can maintain a stable operating state for a long time, reducing maintenance costs.
[0050] Specifically, during operation, the output shaft of the first drive motor 211 rotates, causing the second connecting rod 212 to rotate. While the second connecting rod 212 rotates, it causes the third connecting rod 213 and the fourth connecting rod 214 to swing, thereby causing the rotating shaft 220 to rotate periodically within a certain angle range.
[0051] See Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the third connecting rod 213 includes a first threaded sleeve 2131, a screw 2132, and a second threaded sleeve 2133. One end of the first threaded sleeve 2131 is hinged to the second end of the second connecting rod 212, and one end of the second threaded sleeve 2133 is hinged to the first end of the fourth connecting rod 214. The first end of the screw 2132 is provided with a first threaded portion (not shown in the figure), and the second end of the screw 2132 is provided with a second threaded portion (not shown in the figure). The first threaded sleeve 2131 cooperates with the first threaded portion, and the second threaded sleeve 2133 cooperates with the second threaded portion.
[0052] By configuring the third link 213 to include a first threaded sleeve 2131, a screw 2132, and a second threaded sleeve 2133, the overall length of the third link 213 can be adjusted by screwing the first threaded sleeve 2131 and the second threaded sleeve 2133 into the screw 2132. This adjusts the swing range of the fourth link 214 and the rotating shaft 220, thereby adjusting the starting and ending range of the breaking member 232. Furthermore, by adjusting the starting and ending range of the breaking member 232, interference between the breaking member 232 and the frame 100 during operation can be prevented, compensating for dimensional errors or positional deviations that may occur during manufacturing and assembly.
[0053] It should be noted that the lengths of the first threaded portion and the second threaded portion can be the same or different, and the lengths of the first threaded sleeve 2131 and the second threaded sleeve 2133 can be the same or different.
[0054] According to some embodiments of the present invention, the first threaded portion and the second threaded portion have opposite thread directions.
[0055] By setting the threads of the first threaded part and the second threaded part to opposite directions, during adjustment, it is not necessary to remove the first threaded sleeve 2131 and the second threaded sleeve 2133. The overall length of the third connecting rod 213 can be increased or decreased by directly rotating the screw 2132. Furthermore, the length of the first threaded sleeve 2131 and the second threaded sleeve 2133 screwed into the screw 2132 can be adjusted from both sides simultaneously, thereby improving the adjustment speed.
[0056] See Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, it further includes two lifting mechanisms 300 corresponding one-to-one with the two chaff-breaking mechanisms 200, and the two lifting mechanisms 300 are spaced apart on the frame 100 along a first direction; the lifting mechanism 300 includes a second drive assembly 310 and a lifting bracket 320, and the first side of the lifting bracket 320 ( Figure 4 The upper side shown is rotatably connected to the frame 100, and the second side of the lifting bracket 320 (as shown) Figure 4 The lower side shown is located inside the corresponding stalk breaking member 232 to drive the corresponding stalk breaking member 232 to switch between the working position and the storage position. The second drive assembly 310 is connected to the lifting bracket 320 to drive the second side of the lifting bracket 320 to lift or lower.
[0057] By setting two lifting mechanisms 300 corresponding one-to-one with the two stalk-breaking mechanisms 200, the lifting mechanism 300 can lift the stalk-breaking component 232 of the corresponding stalk-breaking mechanism 200 during operation, preventing it from interfering with the stalk-breaking or stalk-breaking operation. When the lifting mechanism 300 is running, the second drive component 310 drives the second side of the lifting bracket 320 to rotate around the rotational connection point between the first side of the lifting bracket 320 and the frame 100, realizing the lifting or lowering action, and driving the corresponding stalk-breaking component 232 to be lifted or lowered. When lifting, the second drive component 310 drives the second side of the lifting bracket 320 to rise, and the second side of the lifting bracket 320 drives the corresponding stalk-breaking component 232 to rise. When lowering, the second drive component 310 drives the second side of the lifting bracket 320 to fall, and the corresponding stalk-breaking component 232 can be lowered under its own gravity.
[0058] Specifically, during the stalk-lifting operation, the corresponding lifting mechanism 300 can be used to lift the stalk-breaking mechanism 200, which serves as the stalk-breaking mechanism, to prevent its stalk-breaking component 232 from interfering with the stalk-lifting operation. After the stalk-lifting operation is completed, the corresponding lifting mechanism 300 can be used to lift the stalk-breaking mechanism 200, which serves as the stalk-lifting mechanism, to prevent it from interfering with the stalk-breaking operation, and then the corresponding lifting mechanism 300 can be used to lower the stalk-breaking mechanism 200 to perform the stalk-breaking operation.
[0059] The second drive assembly 310 can also be implemented in various ways as described in the prior art. For example, a motor drives a linkage mechanism to move, and the linkage mechanism causes the second side of the lifting bracket 320 to swing within a certain angle range; or a motor can be directly connected to the first side of the lifting bracket 320 for transmission, and the output shaft of the motor can be controlled to rotate in a set direction to cause the second side of the lifting bracket 320 to swing within a certain angle range.
[0060] Of course, the second drive component 310 may also employ other methods known in the prior art, and there is no limitation thereto.
[0061] See Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, the second drive assembly 310 includes a second drive motor 311, a fifth link 312 and a sixth link 313. The second drive motor 311 is mounted on the frame 100. The first end of the fifth link 312 is connected to the output shaft of the second drive motor 311. The second end of the fifth link 312 is hinged to the first end of the sixth link 313. The second end of the sixth link 313 is connected to the lifting bracket 320 to drive the second side of the lifting bracket 320 to be raised or lowered.
[0062] By configuring the second drive assembly 310 into a structure including a second drive motor 311, a fifth link 312, and a sixth link 313, precise control of the lifting bracket 320 can be achieved, allowing the second side of the lifting bracket 320 to be raised or lowered within a set range. The lifting bracket 320 can be adjusted as needed to ensure precise control of its position.
[0063] Specifically, the second drive motor 311 drives the fifth link 312 and the sixth link 313 to swing, which ultimately acts on the second side of the lifting bracket 320 and causes it to rotate around the rotation connection point between the first side of the lifting bracket 320 and the frame 100, thereby achieving lifting or lowering.
[0064] See Figures 1 to 4 As shown, according to some embodiments of the present invention, both lifting mechanisms 300 are located between the two stalk breaking mechanisms 200, and the two second drive motors 311 are located on opposite sides of the frame 100.
[0065] By placing both lifting mechanisms 300 between the two stalk-breaking mechanisms 200, it is easier for the lifting mechanisms 300 to lift or directionally move the corresponding stalk-breaking pieces 232, and it also reduces the space occupied by the lifting mechanisms 300, improving the overall compactness of the device. By placing the two second drive motors 311 on opposite sides of the frame 100, it is easier to install and fix the two second drive motors 311, avoiding the interference that may occur when they are installed on the same side.
[0066] See Figure 3 As shown, according to some embodiments of the present invention, in the two shovel teeth 200, the two outermost shovel teeth 233 are formed with a first material guiding structure 234 for shoveling the material inward, and the shovel teeth 233 between the two outermost shovel teeth 233 are formed with a second material guiding structure 235 for shoveling the material to both sides.
[0067] By setting a first material guiding structure 234 on the two outermost shovel teeth 233 for shoveling the material inward, and setting a second material guiding structure 235 on the shovel teeth 233 between the two outermost shovel teeth 233 for shoveling the material to both sides, the shovel teeth 233 in the middle part can achieve the task of lifting and breaking the stalks, while preventing the two outermost shovel teeth 233 from pushing the mash to the edge of the trough 400 and preventing the mash from being squeezed.
[0068] Specifically, see Figure 3 As shown, the first guiding structure 234 includes two first guiding inclined surfaces that are symmetrical from left to right, and the second guiding structure 235 includes a second guiding inclined surface that is inclined inward. When the stalk is lifted, the two adjacent first guiding inclined surfaces (or the adjacent first guiding inclined surfaces and the second guiding inclined surfaces) of the adjacent stalk lifting parts 232 in the same stalk breaking mechanism 200 can be used to shovel the mash to form a "stalk". When breaking the stalk, the shovel teeth 233 can be used to drive the "stalk" to loosen.
[0069] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first end of the first connecting rod 231 is detachably connected to the rotating shaft 220.
