Description

Technical Field

[0001] The present invention relates to the technical field of liquor drying equipment, and in particular to a side-swept drying stem-breaking device and a side-swept drying stem-breaking system. Background Art

[0002] In the brewing process of Maotai-flavor liquor, the air-drying process occupies an important position. The traditional air-drying process has relatively complex steps, mainly including the process of taking the mash out of the steamer, spreading it on the ground, building and breaking ridges, crushing it, raking it, spreading the tailings, spreading koji powder, turning and mixing it, cooling it, and piling it for fermentation. Specifically, workers use a crane and a shovel to evenly spread the mash on the ground, build and break ridges barefoot, use special tools to crush and rake the mash, then sprinkle the tailings and koji powder, mixing while spreading, and after multiple turning and mixing, cool it naturally or use a blower to accelerate cooling, completing the cooling and koji adding process. However, due to the high temperature of the mash just taken out of the steamer, the traditional air-drying and koji adding process is difficult to operate, and it is easy to burn workers and has high labor intensity. In addition, manual operations are greatly affected by human factors, such as uneven breaking of the mash, uneven spreading of the wine tail and koji powder, insufficient mixing, and uneven heat dissipation, all of which may directly affect the implementation of subsequent processes and ultimately affect the output and quality of the wine.

[0003] To address the shortcomings of manual spreading and airing, a number of mechanical devices have been developed to replace manual spreading operations. For example, conveyor chains are used to spread the mash flat, and toothed breakup mechanisms are designed to rake it up. However, existing mechanical devices are unable to perform the traditional stem removal and stem breaking functions. Furthermore, after koji powder is added, it often adheres to the upper layer of the mash, and the breakup mechanism is unable to effectively rake the lower layer, preventing the lower layer from fully mixing with the koji powder and preventing simultaneous cooling and moisture volatilization. Summary of the Invention

[0004] The present invention provides a device for lifting and breaking stems of off-center drying and an off-center drying and a system for lifting and breaking stems, which are used to solve the problem that existing mechanical equipment cannot effectively realize the functions of lifting and breaking stems, and cannot evenly mix koji powder, synchronously cool down and evaporate water, resulting in insufficient treatment of the bottom material.

[0010] According to the eccentric drying and stem breaking device provided by the present invention, the thread rotation directions of the first threaded portion and the second threaded portion are opposite.

[0011] The eccentric drying and stem breaking device provided by the present invention also includes two lifting mechanisms corresponding to the two stem breaking mechanisms, and the two lifting mechanisms are arranged on the frame at intervals along the first direction; the lifting mechanism includes a second driving component 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 on the inner side of the corresponding stem breaking component to drive the corresponding stem breaking component to switch between the working position and the storage position, and the second driving component is transmission-connected to the lifting bracket to drive the second side of the lifting bracket to lift or lower.

[0012] According to the eccentric drying and stem breaking device provided by the present invention, the second driving assembly includes a second driving motor, a fifth connecting rod and a sixth connecting rod. The second driving motor is arranged on the frame, the first end of the fifth connecting rod is connected to the output shaft of the second driving motor, the second end of the fifth connecting rod is hinged to the first end of the sixth connecting rod, and the second end of the sixth connecting rod is connected to the lifting bracket to drive the second side of the lifting bracket to lift or lower.

[0033] The following combination Figures 1 to 7 The invention provides a device for raising and breaking stems of vegetables in an off-center drying stall and a system for raising and breaking stems of vegetables in an off-center drying stall.

[0034] See also Figures 1 to 4 As shown, the stalk-breaking device for spreading and airing crops provided by an embodiment of the present invention includes: a frame 100 and two stalk-breaking mechanisms 200.

[0035] Two stem-breaking mechanisms 200 are arranged on the frame 100 at intervals along the first direction. The stem-breaking mechanism 200 includes a first driving assembly 210, a rotating shaft 220 and a plurality of stem-breaking units 230. The rotating shaft 220 is rotatably connected to the frame 100. The plurality of stem-breaking units 230 are arranged on the rotating shaft 220 at intervals along the second direction. The stem-breaking unit 230 includes a first connecting rod 231 and a stem-breaking piece 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 stem-breaking piece 232. The second end of the stem-breaking piece 232 is provided with a shovel tooth 233. The first driving assembly 210 is transmission-connected to the rotating shaft 220 to drive the rotating shaft 220 to swing periodically within a set angle range.

[0036] The multiple stem-breaking members 232 in one stem-breaking mechanism 200 are arranged alternately with the multiple stem-breaking members 232 in another stem-breaking mechanism 200.

[0037] It should be noted that the “first direction” and “second direction” mentioned in this embodiment refer to Figure 2As shown in the arrow direction, the first direction can be regarded as the running direction of the frame 100, and the second direction can be regarded as the width direction of the frame 100. Moreover, any of the two stem-raising and breaking mechanisms 200 can be used as a stem-raising mechanism or a stem-breaking mechanism. For example, when the frame 100 moves in the positive direction of the first direction, the stem-raising and breaking mechanism 200 located at the front side can be used as a stem-raising mechanism, and the stem-raising and breaking mechanism 200 located at the rear side can be used as a stem-breaking mechanism; when the frame 100 moves in the negative direction of the first direction, the stem-raising and breaking mechanism 200 located at the rear side can be used as a stem-raising mechanism, and the stem-raising and breaking mechanism 200 located at the front side can be used as a stem-breaking mechanism.

[0038] "Removing the stems of the mash" can be understood as using a stem-removing mechanism to shovel the mash spread in the trough 400 to form "stems" of set spacing. Correspondingly, "breaking the stems of the mash" can be understood as using a stem-breaking mechanism to shovel the "stems" to loosen the "stems".

[0039] The stalk-lifting and stem-breaking device provided by the present invention is configured by arranging two stalk-lifting and stem-breaking mechanisms 200 on the frame 100 at intervals along a first direction. During operation, the front stalk-lifting and stem-breaking mechanism 200 can be used to lift the stalks. Since the stalk-lifting and stem-breaking members 232 in the two stalk-lifting and stem-breaking mechanisms 200 are arranged in a staggered manner, the rear stalk-lifting and stem-breaking mechanism 200 can be used to break the stalks after the stalks are lifted. During both lifting and stem-breaking, 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 stalk-lifting and stem-breaking members 232 to perform periodic lifting or stem-breaking actions, which can increase the contact area between the mash and the air, improve the spreading efficiency, and reduce the intensity of manual labor.

[0040] Specifically, the off-center drying stem-breaking device provided by the invention includes a frame 100 and two stem-breaking mechanisms 200.

[0041] Among them, the frame 100 is used to provide an installation position for the two stem-breaking mechanisms 200 and other necessary components, and can be configured to be movably set on the material trough 400, and then the two stem-breaking mechanisms 200 and other necessary components are driven by the frame 100 to move along the length direction of the material trough 400.

[0042] The stem-breaking mechanism 200 is used to automatically remove or break the stems of the mash located in the trough 400, so that the mash can fully contact with the air during the stem-breaking process and improve the drying efficiency. The stem-breaking mechanism 200 includes a first drive assembly 210, a rotating shaft 220, and a plurality of stem-breaking units 230. The rotating shaft 220 is rotatably connected to the frame 100, and the first drive assembly 210 is transmission-connected to the rotating shaft 220 to drive the rotating shaft 220 to periodically swing within a set angle range, thereby driving the plurality of stem-breaking units 230 to exert a shoveling action on the mash to achieve stem removal or stem breaking. The number of stem-breaking units 230 can be set according to actual needs, as long as it can cover all the blanks in the trough 400, and there is no limitation on this.

[0043] The stem-breaking unit 230 includes a first connecting rod 231 and a stem-breaking member 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 stem-breaking member 232. The second end of the stem-breaking member 232 is provided with shovel teeth 233. When the rotating shaft 220 periodically swings within a set angle range, it can drive the first connecting rod 231 to swing synchronously and drive the shovel teeth 233 to perform a shoveling motion. Because the ends of the shovel teeth 233 are supported by the mash or the wall of the trough 400 during shoveling, there is no need for an additional connecting rod to support the stem-breaking member 232.

[0044] The first drive assembly 210 can be implemented in various ways known in the art. For example, a motor can drive a connecting rod mechanism, which in turn drives the rotating shaft 220 to periodically rotate within a certain angular range. Alternatively, a motor can be directly connected to the rotating shaft 220 to control the output shaft of the motor to reciprocate within a certain angular range, thereby driving the rotating shaft 220 to periodically rotate within a certain angular range.

[0045] Of course, the first driving component 210 may also adopt other methods known in the prior art, which is not limited to this.

[0046] See also Figures 1 to 4 As shown, in this embodiment, both rotating shafts 220 are hexagonal (with a regular hexagonal cross-section). Bearing blocks 110 are provided on either side of the frame 100, with their ends rotatably connected to the respective sides of the frame 100, corresponding to the bearing blocks 110. Five stem-breaking units 230 are spaced apart on one rotating shaft 220, and six stem-breaking units 230 are spaced apart on the other rotating shaft 220. All stem-breaking units 230 can cover the entire lateral area within the trough 400.

[0047] See also 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 arranged 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, and the second end of the fourth connecting rod 214 is connected to the rotating shaft 220.

[0048] By setting the first drive component 210 as a connecting rod mechanism including a first drive motor 211, a second connecting rod 212, a third connecting rod 213 and a fourth connecting rod 214, the transmission mechanism of the connecting rod mechanism can be used to drive the rotating shaft 220 to achieve periodic swing, thereby simplifying the complexity of the control system and improving the stability and efficiency of the operation. In addition, the motion transmission of the connecting rod mechanism has high reliability and durability, can maintain a stable operating state for a long time, and reduce maintenance costs.

[0049] Specifically, during operation, the output shaft of the first drive motor 211 rotates, driving the second connecting rod 212 to rotate. The second connecting rod 212 rotates while driving the third connecting rod 213 and the fourth connecting rod 214 to swing, thereby driving the rotating shaft 220 to rotate periodically within a certain angle range.

[0050] See also Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the third connecting rod 213 includes a first screw sleeve 2131, a screw rod 2132 and a second screw sleeve 2133, one end of the first screw sleeve 2131 is hinged to the second end of the second connecting rod 212, and one end of the second screw sleeve 2133 is hinged to the first end of the fourth connecting rod 214; the first end of the screw rod 2132 is provided with a first threaded portion (not shown in the figure), and the second end of the screw rod 2132 is provided with a second threaded portion (not shown in the figure), the first screw sleeve 2131 cooperates with the first threaded portion, and the second screw sleeve 2133 cooperates with the second threaded portion.

[0051] By configuring the third connecting rod 213 to include a first threaded sleeve 2131, a screw rod 2132, and a second threaded sleeve 2133, the overall length of the third connecting rod 213 can be adjusted by the length of the first threaded sleeve 2131 and the second threaded sleeve 2133 screwed into the screw rod 2132, thereby adjusting the swing start and end ranges of the fourth connecting rod 214 and the rotating shaft 220, and thus adjusting the start and end ranges of the breaking stem member 232. In addition, by adjusting the start and end ranges of the breaking stem member 232, it is possible to prevent the breaking stem member 232 from interfering with the frame 100 during operation, thereby compensating for dimensional errors or positional deviations that may occur during the manufacturing and assembly processes.

[0052] It should be noted that the lengths of the first threaded portion and the second threaded portion may be the same or different, and the lengths of the first screw sleeve 2131 and the second screw sleeve 2133 may be the same or different.

[0053] According to some embodiments of the present invention, the first threaded portion and the second threaded portion have opposite thread directions.

[0054] By setting the threads of the first threaded portion and the second threaded portion to rotate in opposite directions, there is no need to remove the first screw sleeve 2131 and the second screw sleeve 2133 during adjustment. The overall length of the third connecting rod 213 can be increased or decreased by directly rotating the screw 2132, and the length of the first screw sleeve 2131 and the second screw sleeve 2133 screwed into the screw 2132 can be adjusted at the same time on both sides, thereby improving the adjustment speed.

[0055] See also Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, two lifting mechanisms 300 corresponding to the two stem-breaking mechanisms 200 are further included, and the two lifting mechanisms 300 are spaced apart along the first direction on the frame 100; the lifting mechanism 300 includes a second driving assembly 310 and a lifting bracket 320, and the first side of the lifting bracket 320 ( Figure 4 ) is rotatably connected to the frame 100, and the second side of the lifting bracket 320 ( Figure 4 The lower side shown in the figure is located on the inner side of the corresponding stem-breaking member 232 to drive the corresponding stem-breaking member 232 to switch between the working position and the storage position. The second drive component 310 is connected to the lifting bracket 320 to drive the second side of the lifting bracket 320 to lift or lower.

[0056] By setting up two lifting mechanisms 300 corresponding to the two stem-breaking mechanisms 200, the lifting mechanism 300 can be used to lift the stem-breaking member 232 of the corresponding stem-breaking mechanism 200 during operation to prevent it from interfering with the stem-raising or stem-breaking operation. When the lifting mechanism 300 is in operation, the second drive component 310 drives the second side of the lifting bracket 320 to rotate around the rotation connection point between the first side of the lifting bracket 320 and the frame 100, thereby realizing the lifting or lowering action and driving the corresponding stem-breaking member 232 to be lifted or lowered. When lifting, the second drive component 310 drives the second side of the lifting bracket 320 to lift up, and the second side of the lifting bracket 320 drives the corresponding stem-breaking member 232 to lift. When lowering, the second drive component 310 drives the second side of the lifting bracket 320 to lower, and the corresponding stem-breaking member 232 can be lowered under the action of its own gravity.

[0057] Specifically, during the stem pulling operation, the corresponding lifting mechanism 300 can be used to lift the stem pulling and breaking mechanism 200 as the stem breaking mechanism to prevent the stem pulling and breaking member 232 from interfering with the stem pulling operation. After the stem pulling operation is completed, the corresponding lifting mechanism 300 can be used to lift the stem pulling and breaking mechanism 200 as the stem pulling mechanism to prevent it from interfering with the stem breaking operation, and the corresponding lifting mechanism 300 can be used to lower the stem pulling and breaking mechanism 200 as the stem breaking mechanism to perform the stem breaking operation.

[0058] The second drive assembly 310 can also be implemented in various ways known in the art. For example, a motor can drive a connecting rod mechanism to move, thereby causing the second side of the lifting bracket 320 to swing within a certain angle range. Alternatively, a motor can be directly connected to the first side of the lifting bracket 320, and the motor's output shaft 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.

[0059] Of course, the second driving component 310 may also adopt other methods known in the prior art, which is not limited to this.

[0060] See also 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 arranged 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, and 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 lift or lower.

[0061] By setting the second drive component 310 to a structure including a second drive motor 311, a fifth connecting rod 312 and a sixth connecting rod 313, precise control of the lifting bracket 320 can be achieved, so that the second side of the lifting bracket 320 can be lifted or lowered within a set range. The lifting bracket 320 can be adjusted as needed to ensure precise control of its position.

[0062] Specifically, the second drive motor 311 drives the fifth connecting rod 312 and the sixth connecting rod 313 to swing, and finally acts on the second side of the lifting bracket 320, and causes it to rotate around the rotating connection point between the first side of the lifting bracket 320 and the frame 100, thereby achieving lifting or lowering.

[0063] See also Figures 1 to 4 As shown, according to some embodiments of the present invention, the two lifting mechanisms 300 are located between the two stem-breaking mechanisms 200, and the two second drive motors 311 are located on different sides of the frame 100.

[0064] By arranging the two lifting mechanisms 300 between the two stem-breaking mechanisms 200, it is possible to facilitate the lifting mechanisms 300 to lift or orient the corresponding stem-breaking members 232, reduce the space occupied by the lifting mechanisms 300, and improve the overall compactness of the device. By arranging the two second drive motors 311 on opposite sides of the frame 100, it is possible to facilitate the installation and fixation of the two second drive motors 311, avoiding the situation where the two second drive motors 311 are easily installed on the same side and interfere with each other.

[0065] See also Figure 3 As shown, according to some embodiments of the present invention, in the two stem-breaking mechanisms 200, the two outermost shovel teeth 233 form a first material guide structure 234 for shoveling the material inward, and the shovel teeth 233 between the two outermost shovel teeth 233 form a second material guide structure 235 for shoveling the material to both sides.

[0066] By providing a first material guide structure 234 for shoveling the material inward on the two outermost shovel teeth 233, and providing a second material guide structure 235 for shoveling the material to both sides on the shovel teeth 233 located between the two outermost shovel teeth 233, while ensuring that the shovel teeth 233 in the middle part can perform the stem lifting and breaking operations, the two outermost shovel teeth 233 are prevented from pushing the mash to the edge of the material trough 400 and preventing the mash from being squeezed.

[0067] Specifically, see Figure 3 As shown, the first material guide structure 234 includes two first material guide slopes that are symmetrical on the left and right, and the second material guide structure 235 includes a second material guide slope that is inclined inward. When removing stems, the two adjacent first material guide slopes (or adjacent first material guide slopes and second material guide slopes) of the adjacent stem breaking members 232 in the same stem breaking mechanism 200 can be used to shovel the mash to form "stems". When breaking the stems, the shovel teeth 233 can use the shovel teeth 233 to drive the "stems" to loosen.

[0068] See also 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 .

[0069] By configuring the first end of the first connecting rod 231 and the rotating shaft 220 to be detachably connected, the distance between adjacent stem-breaking members 232 in the same stem-breaking mechanism 200 can be adjusted so that the distance between stem-breaking and stem-breaking meets actual needs.

[0070] Specifically, in this embodiment, the first end of the first connecting rod 231 is detachably connected to the rotating shaft 220 through a clamp and a threaded fastener.

[0071] The following is a description of the off-center drying and stem breaking system provided by the present invention. The off-center drying and stem breaking system described below and the off-center drying and stem breaking device described above can be referenced to each other.

[0072] See also Figure 7 As shown, the off-center drying and stem breaking system provided by the embodiment of the present invention includes: a material trough 400 and an off-center drying and stem breaking device. The off-center drying and stem breaking device can be movably arranged in the material trough 400, and the stem breaking member 232 is located in the material trough 400.

[0073] The off-center drying and stem-breaking system provided by the present invention adopts the above-mentioned off-center drying and stem-breaking device, and therefore can realize stem-lifting and stem-breaking operations, and can increase the contact area between the mash and the air, improve the drying efficiency, and reduce manual labor intensity.
