Description

Technical Field

[0001] The present application relates to the technical field of Maotai-flavor liquor, and in particular to an automatic curing device for sealing mud of Maotai-flavor liquor. Background Art

[0002] In the production process of Maotai-flavor liquor, after the fermented grains are piled up and fermented on the drying hall, they will be transferred to the cellar for the next stage of fermentation. At this time, the local purple-red mud is needed to seal the cellar to keep the cellar in a relatively anaerobic state to complete the alcohol fermentation process. The thickness of the cellar mud is 5 to 8 cm, thick around and slightly thin in the middle, in the shape of a turtle's back. During the fermentation process of the fermented grains in the cellar, a large amount of gas will be produced and discharged through the cellar mud, and the fermentation process will cause the fermented grains to settle, which can easily cause the cellar mud to crack and leak. In addition, the surface moisture of the cellar mud is very easy to evaporate, causing the cellar mud to dry and crack. Therefore, after the cellar is sealed, a special person needs to be arranged to be responsible for the cellar management work, and the sealing mud should be artificially replenished with water, tamped, and smoothed every day. The cellar management workers should first evenly sprinkle an appropriate amount of water on the cellar mud, and then use a mud palm board to pat and tighten the cellar mud to prevent the cellar mud from loosening, cracking and leaking. Finally, the surface of the cellar mud should be smoothed to keep the sealing mud properly moisturized, well sealed, and beautiful in appearance.

[0003] At present, in the production of Maotai-flavor liquor, the cellar management work after the mash is put into the cellar and the cellar sealing process is completed manually. Each team has a full-time cellar management position, and the sealing mud is replenished with water and compacted on a regular basis every day. This has the following defects:

[0004] First, the cellar workers need to maintain more than ten cellars every day, which is a heavy workload and labor intensity. They also need to be on duty every day throughout the year, which results in high labor costs.

[0005] Second: If the pit mud is dehydrated and cracked during the off-duty period, it cannot be discovered and handled in time;

[0006] Third: The quality of work done by different cellar managers is uneven and unstable.

[0033] The embodiment of the present application provides an automatic maintenance device for the sealing mud of Maotai-flavor liquor, which adopts an automated mechanical device to replace the daily manual work of sprinkling water, patting and smoothing the cellar mud, thereby improving work efficiency, saving human resources, and being able to deal with problems such as water shortage and cracking in a timely manner. At the same time, it is more uniform than manual water replenishment and will not cause local water accumulation due to excessive water replenishment.

[0034] The following is a detailed description of the automatic curing device for sealing the cellar mud of a Maotai-flavor liquor provided in this embodiment. Figure 1 , Figure 4 As shown, it includes: a frame body 1, a multi-axis linear module 3, a three-dimensional scanner 4, a patting and smoothing device 5 and a water replenishing device 6. The frame body 1 is arranged above the cellar 2 and can be moved along a plurality of cellars 2 arranged side by side. The multi-axis linear module 3 is arranged on the frame body 1 and can move along multiple axis directions; the three-dimensional scanner 4, the patting and smoothing device 5 and the water replenishing device 6 are all arranged on the multi-axis linear module 3. The three-dimensional scanner 4 can perform a three-dimensional scanning on the cellar sealing mud to obtain the geometric shape model, crack position and cellar mud color information of the cellar sealing mud surface. The patting and smoothing device 5 can perform the cellar sealing mud curved surface operation according to the geometric shape model scanned by the three-dimensional scanner 4. The water replenishing device 6 can perform water replenishing operation on the cellar sealing mud according to the crack position and cellar mud color information on the cellar sealing mud surface scanned by the three-dimensional scanner 4.

[0035] In this embodiment, the frame body 1 can move along a plurality of cellars 2 arranged side by side, and use a three-dimensional scanner 4 to perform a three-dimensional scan on the sealing mud to obtain a geometric shape model, crack position and cellar mud color information on the surface of the sealing mud. Thus, the tamping and smoothing device 5 can perform the sealing mud curved surface operation according to the geometric shape model scanned by the three-dimensional scanner 4, and the water replenishing device 6 can perform water replenishment operation on the sealing mud according to the crack position and cellar mud color information on the surface of the sealing mud scanned by the three-dimensional scanner 4. Thus, the use of an automated mechanical device replaces the manual daily watering, tamping and smoothing of the cellar mud. The work is improved, work efficiency is improved, human resources are saved, and by planning the moving path of the frame body 1, one device can manage multiple cellars 2. Compared with the daily scheduled maintenance of manual cellar management, the device can inspect the status of the sealing mud 24 hours a day, and can deal with problems such as water shortage and cracking in time. In addition, the device can collect the sedimentation data of the cellar mud during the fermentation of the mash through the three-dimensional scanner 4, which has a certain reference significance for the fermentation of the mash in the cellar. The water replenishment amount is scientifically set based on the cracks and color of the cellar mud obtained by the three-dimensional scanner 4, which is more uniform than manual water replenishment and will not cause local water accumulation due to excessive water replenishment.

[0036] Please refer to Figure 1 , Figure 2 As shown, in this embodiment, it should be noted that rails 21 are respectively provided on both sides of the multiple cellars 2 arranged side by side, and the rails 21 are extended along the arrangement direction of the multiple cellars 2; the frame body 1 is connected to the rails 21 by rollers 11, and is controlled and driven by the control box 12. Rails 21 are provided on both sides of the multiple cellars 2 arranged side by side, and the frame body 1 can move along the rails 21 in a directional manner, and then can be arbitrarily positioned and stopped at a position above a certain cellar 2, so that multiple cellars 2 can be managed by using one frame body 1. Preferably, the frame body 1 in this embodiment adopts an AGV (Automated Guided Vehicle), which can autonomously complete a series of actions and other functions according to a pre-set path.

[0037] Please refer to Figure 1 , Figure 3 As shown, in this embodiment, it should be noted that the multi-axis linear module 3 includes an X-axis linear module 31, a Y-axis linear module 32 and a Z-axis linear module 33. The X-axis linear module 31 is fixed on the frame body 1, and together with the Y-axis linear module 32 and the Z-axis linear module 33, a gantry structure is formed. The multi-axis linear module 3 can realize lateral, longitudinal and vertical movement, and the movement of each three-dimensional coordinate point within the working range can be completed through the mutual cooperation between the X-axis linear module 31, the Y-axis linear module 32 and the Z-axis linear module 33.

[0038] In an achievable manner, there are two X-axis linear modules 31, and the two X-axis linear modules 31 are parallel to each other. There are two Z-axis linear modules 33, and the two Z-axis linear modules 33 and the two X-axis linear modules 31 are respectively arranged correspondingly. In other words, each X-axis linear module 31 is configured with a Z-axis linear module 33, and the Z-axis linear module 33 is connected to the X-axis linear module 31 through the first slider 34, so that the Z-axis linear module 33 can slide along the length direction of the X-axis linear module 31 through the first slider 34, thereby realizing the movement of the device along the X direction. The Y-axis linear module 32 spans between the two Z-axis linear modules 33, and the Y-axis linear module 32 is connected to the Z-axis linear module 33 through the second slider 35, so that the Y-axis linear module 32 can slide along the height direction of the Z-axis linear module 33 through the second slider 35, thereby realizing the movement of the device along the Z direction. The patting and smoothing device 5 and the water replenishing device 6 are connected to the Y-axis linear module 32 through the third slider 36. Therefore, the patting and smoothing device 5 and the water replenishing device 6 can slide along the length direction of the Y-axis linear module 32 through the third slider 36, thereby realizing the movement of the device along the Y direction.

[0039] Therefore, in this embodiment, through the mutual cooperation between the X-axis linear module 31, the Y-axis linear module 32 and the Z-axis linear module 33, the movement of the device in the horizontal, longitudinal and vertical directions can be realized, which makes it easier for the patting and leveling device 5 and the water replenishing device 6 to operate on the sealing mud.

[0040] Please refer to Figure 1 , Figure 5 , Figure 6 As shown in FIG. 7 , in this embodiment, it should be noted that the tamping and leveling device 5 includes a mud palm plate 51, a crank connecting rod mechanism 52 and a power unit 53. The crank connecting rod mechanism 52 is arranged between the power unit 53 and the mud palm plate 51. The power unit 53 controls the crank connecting rod mechanism 52 to drive the mud palm plate 51 to reciprocate up and down to achieve the operation of sealing the cellar mud curved surface. Preferably, the power unit 53 is set as an electric motor.

[0041] In one feasible manner, an outer shell 54 is provided on one side of the third slider 36, the power unit 53 is provided outside the outer shell 54, the crank-connecting rod mechanism 52 includes an eccentric wheel 521, a connecting rod 522 and a spring group 523, the eccentric wheel 521 is provided in the outer shell 54, the output end of the power unit 53 extends into the outer shell 54 and is connected to the eccentric wheel 521, the upper end of the connecting rod 522 is connected to the eccentric wheel 521, the lower end of the connecting rod 522 extends vertically out of the outer shell 54, and is connected to the mud palm plate 51 through the spring group 523. The bottom of the outer shell 54 is connected with a first sleeve 541, which is arranged vertically. The upper part of the mud palm plate 51 is provided with a second sleeve 5111, which is also arranged vertically. A sliding sleeve 55 is sleeved between the first sleeve 541 and the second sleeve 5111. The upper end of the sliding sleeve 55 is slidably sleeved in the first sleeve 541, and the lower end of the sliding sleeve 55 is sleeved in the second sleeve 5111. The lower end of the connecting rod 522 is vertically inserted in the sliding sleeve 55, and the lower end of the connecting rod 522 is connected with a disc 5221, and the outer periphery of the disc 5221 contacts the inner peripheral wall of the sliding sleeve 55. The spring group 523 is arranged in the sliding sleeve 55 and includes a first spring 5231 and a second spring 5232. The first spring 5231 is sleeved on the connecting rod 522 and connects the upper surface of the disc 5221 and the top of the sliding sleeve 55. The second spring 5232 connects the lower surface of the disc 5221 and the upper part of the mud palm plate 51. Thus, the power unit 53 drives the eccentric wheel 521 to rotate in the outer shell 54, and drives the connecting rod 522 to do up and down reciprocating motion by the rotation of the eccentric wheel 521, so that the first spring 5231 and the second spring 5232 continuously absorb and release energy, and drive the sliding sleeve 55 to slide up and down in the first sleeve 541, and then drive the mud palm plate 51 to do a rapid impact motion as a whole to compact the sealing mud.

[0042] It should also be noted that the mud palm plate 51 includes an upper top plate 511 and a lower top plate 512, the second sleeve 5111 is arranged in the middle position of the upper top plate 511, and the second spring 5232 is connected to the upper top plate 511, the middle position between the upper top plate 511 and the lower top plate 512 is hinged by a ball joint 513, and an electric push rod 514 is also arranged between the upper top plate 511 and the lower top plate 512, the electric push rod 514 is arranged at the end positions of the upper top plate 511 and the lower top plate 512, and the upper and lower ends of the electric push rod 514 are respectively hinged to the upper top plate 511 and the lower top plate 512, thereby the inclination angle of the lower top plate 512 can be adjusted by the electric push rod 514, so that it is more suitable for sealing mud operations.

[0043] Please refer to Figure 1 , Figure 3 as well as Figure 8As shown, in this embodiment, it is also necessary to explain that the water replenishing device 6 includes a water tank 61, a water pipe 62 and a nozzle 63. The water tank 61 is arranged on the frame body 1, and the nozzle 63 is arranged on the third slider 36 of the Y-axis linear module 32, and can move with the third slider 36. The water pipe 62 is connected to the water tank 61 and the nozzle 63. Therefore, the water in the water tank 61 reaches the position of the nozzle 63 through the water pipe 62, and then is sprayed out through the nozzle 63 to replenish the sealing mud.

[0044] The implementation principle of this embodiment is as follows: the AGV trolley drives the device to move to the top of the cellar 2, and the three-dimensional scanner 4 scans and obtains the geometric shape model, crack position and cellar mud color information of the cellar mud surface, and then the water replenishing device 6 replenishes water according to the color and crack position of the cellar mud, replenishes less water in the moist and bright-colored parts of the cellar mud, and appropriately replenishes water in the cracked and light-colored parts of the cellar mud, and the tamping and smoothing device 5 moves spirally from the middle to the surrounding according to the scanned three-dimensional model, controls the mud palm plate 51 to always vibrate and tamp the cellar mud closely to the surface of the cellar mud, stops vibrating after the entire surface of the cellar mud is tamped, and then moves spirally from the outer circle to the inner circle, and the mud palm plate 51 is slightly tilted to smooth the cellar mud to make the surface of the cellar mud smooth. By adopting an automated mechanical device to replace the manual daily watering, tamping, and smoothing of the cellar mud, work efficiency is improved and human resources are saved.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
