Description

Technical Field

[0001] This invention relates to the field of brewing equipment technology, and more particularly to a dual-mode mud spreading device for sealing cellars and its control method. Background Technology

[0002] Sealing the fermentation pits is a crucial step in the brewing process of strong-aroma and sauce-aroma baijiu. This involves using sealing mud, a special material used to cover the pit openings. Specifically, after the mash is spread into the pits in the brewing workshop, the sealing mud is used to seal the fermentation tanks, creating a closed environment. The sealing mud has a certain degree of viscosity and moisture to ensure a tight bond with the pit openings, guaranteeing proper fermentation. Traditionally, the sealing mud was manually transferred to the pits using various shovel-shaped tools, and then shaped using the same tools to form the required form. However, this method is inefficient and unsuitable for automated industrial production. Currently, the spreading process of sealing mud is typically carried out using a combination of mechanical equipment and manual labor.

[0003] Chinese patent document CN117821186B discloses an intelligent mud covering system for sealing kilns, including a mud storage box and a spreading mechanism located on the lower front side of the mud storage box. The spreading mechanism includes a fixing frame located on the lower front side of the mud storage box. Electric push rods are installed in symmetrically arranged mounting openings at the front of the fixing frame. A connecting plate is located at the lower end between the telescopic ends of two electric push rods. Guide rods are slidably connected in sliding openings at the four corners of the connecting plate. A pressure plate is located at the lower end between the four guide rods. Springs are symmetrically distributed at the four corners of the upper surface of the pressure plate, and the springs are movably sleeved on the exterior of the vertically adjacent guide rods. Through the spreading mechanism, the kiln mud becomes dense and compact with uniform thickness, reducing gaps during kiln mud covering, improving the spreading and sealing effect, and enabling rapid leveling of the mud at the kiln opening, achieving efficient and automated mud covering operations for sealing kilns.

[0004] Because the fermentation process of mash requires a constant anaerobic environment, as moisture evaporates from the sealing mud, cracks may appear, allowing air to enter and causing fermentation failure. Therefore, the spreading of sealing mud is not only necessary for the initial covering of mash but also requires daily maintenance. However, the initial sealing mud has a high moisture content, while the mud used for maintenance has a low moisture content, resulting in different raw material compositions for spreading in these two states. The aforementioned equipment has a simple structure for its mud storage tank and discharge port, which is insufficient to meet the usage requirements. Furthermore, the initial spreading of sealing mud requires strict sealing, while maintenance requires high efficiency and speed to reduce the risk of oxygen infiltration. The aforementioned equipment has a simple working mode and low level of intelligence.

[0005] In conclusion, there is an urgent need for a dual-mode mud spreading device for sealing pits and its control method to solve the above problems. Summary of the Invention

A fifth motor is connected to the end of the connecting rod away from the discharge pipe. A stop block is connected to the end of the connecting rod away from the fifth motor. The stop block is designed in a pointed shape. The pointed structure is provided with a curved protrusion. The curved protrusion, in conjunction with rotation, can throw the raw material downwards towards the device, thereby achieving water or flowable sealing mud coverage and improving paving efficiency.

[0036] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0037] Example 1:

[0038] Please refer to a dual-mode mud spreading device for sealing pits. Figures 1-8 To accommodate the needs of two different modes, this device is equipped with two storage structures: mud storage tank 1 and maintenance storage tank 2.

[0039] like Figure 1As shown, the mud storage tank 1 is located at one end of the device, and the maintenance storage tank 2 is located at the other end. A first spiral conveyor frame 14 is installed inside the mud storage tank 1, and a first sidewall 12 is provided at the end of the mud storage tank 1 away from the maintenance storage tank 2. The first spiral conveyor frame 14 is mounted on the first sidewall 12, and a first motor 11 is connected to the end away from the maintenance storage tank 2. A second spiral conveyor frame 24 is installed inside the maintenance storage tank 2, and a second sidewall 22 is provided at the end of the maintenance storage tank 2 away from the mud storage tank 1. The second spiral conveyor frame 24 is mounted on the second sidewall 22, and a second motor 21 is connected to the end away from the first motor 11. Since the mud storage tank 1 transports the initial spreading mud for sealing the pit, which has a high viscosity, the first spiral conveyor frame 14 requires a high-power motor. Conversely, the maintenance storage tank 2 transports maintenance mud or water for sealing the pit, which has a low viscosity, and the second spiral conveyor frame 24 requires a low-power motor. Therefore, the power of the selected second motor 21 is less than that of the first motor 11, effectively saving costs.

[0040] To achieve intelligent adjustment of this device, the mud spreading device for sealing the pit is equipped with dual modes of initial spreading and maintenance, which meets the requirements of efficient spreading in both initial use and maintenance states. At the same time, different control methods are adopted for different raw material compositions and different requirements, which has a high degree of intelligence, strong practicality, and meets the usage requirements in both states.

[0041] like Figure 2 As shown, a first mud outlet pipe 13 is connected to the bottom of the mud storage tank 1, and a second mud outlet pipe 23 is connected to the bottom of the maintenance storage tank 2. A discharge assembly 4 is connected to the bottom of the first mud outlet pipe 13 and the second mud outlet pipe 23. The solenoid valve 41 in the discharge assembly 4 controls the opening and closing of the first mud outlet pipe 13 and the second mud outlet pipe 23. This enables the sealing mud spreading device to be in the initial spreading mode, where the solenoid valve 41 controls the first mud outlet pipe 13 to open and the second mud outlet pipe 23 to close, and the discharge pipe 42 discharges sealing mud of appropriate viscosity. Alternatively, the sealing mud spreading device can be in the maintenance mode, where the solenoid valve 41 controls the second mud outlet pipe 23 to open and the first mud outlet pipe 13 to close, and the discharge pipe 42 discharges water or flowable sealing mud.

[0042] Secondly, such as Figures 6-7As shown, the discharge pipe 42 is fixedly connected below the first mud discharge pipe 13 and the second mud discharge pipe 23. The solenoid valve 41 is installed at the connection position between the discharge pipe 42 and the first mud discharge pipe 13 and the second mud discharge pipe 23. The discharge pipe 42 is bent downwards, and a third spiral conveyor frame 49 is installed inside the discharge pipe 42. A third motor 43 is installed on the top of the third spiral conveyor frame 49, and the third motor 43 controls the third spiral conveyor frame 49 to rotate and convey; thereby achieving efficient discharge of water or mud for sealing pits.

[0043] like Figures 2-3 As shown, a clamp 44 is fixedly installed on the outer wall of the bottom of the discharge pipe 42. A telescopic rod 41 is fixedly connected to the lower part of the clamp 44. A fixing plate 451 is fixedly connected to the end of the telescopic rod 41 away from the clamp 44. A connecting plate 46 is movably connected between the fixing plates 451. A connecting rod 471 is installed inside the connecting plate 46. A fifth motor 47 is connected to the end of the connecting rod 471 away from the discharge pipe 42. A stop block 48 is connected to the end of the connecting rod 471 away from the fifth motor 47. The stop block 48 is set in a pointed shape. A curved protrusion 481 is provided on the pointed structure. The curved protrusion 481, in conjunction with rotation, can throw the raw material downwards to the device, realize the coverage area of ​​water or flowable sealing mud, and improve the paving efficiency.

[0044] This allows the sealing mud spreading device to be in the initial spreading mode, with the telescopic rod 41 extended, controlling the connecting plate 46 away from the outlet end of the discharge pipe 42, so that the sealing mud can be discharged in an orderly manner; when the sealing mud spreading device is in the maintenance mode, the telescopic rod 41 is retracted, controlling the connecting plate 46 to move closer to the outlet end of the discharge pipe 42, and the fifth motor 47 controls the stop block 48 and the protrusion 481 to rotate, increasing the coverage area of ​​water or flowable sealing mud, avoiding material accumulation, and effectively improving spreading efficiency;

[0045] Furthermore, to provide more adjustment methods, such as Figure 5 As shown, a fourth motor 45 is fixedly installed at one end of the fixing plate 451 away from the connecting plate 46, and the fourth motor 45 controls the rotation direction of the connecting plate 46.

[0046] To achieve effective support, such as Figure 1 As shown, a support assembly 3 is fixedly installed below the mud storage tank 1 and the maintenance tank 2. The support assembly 3 includes a support frame 31, which is disposed on the outer wall of the mud storage tank 1 and the maintenance tank 2. A first connecting column 32 is fixedly installed below the support frame 31, and a second connecting column 33 is fixedly installed on the side of the first connecting column 32 away from the discharge pipe 42.

[0047] like Figures 6-7As shown, a compaction component 5 is installed at the bottom of the first connecting column 32. The compaction component 5 includes a pressure roller 51, which is movably installed between the two first connecting columns 32. An installation shaft 52 is installed inside the pressure roller 51, and sliders 53 are connected to both ends of the installation shaft 52. A spring 54 is installed above the sliders 53. A slide rail 34 is provided on the side of the first connecting column 32 near the mud storage box 1. The sliders 53 are fitted into the slide rail 34, and the spring 54 is installed between the inner wall of the slide rail 34 and the top of the slider 53. This achieves the following: the mud spreading device for sealing the kiln is in the initial spreading mode, the compaction component 5 maintains efficient vibration to reduce gaps when covering the kiln mud; and the mud spreading device for sealing the kiln is in the maintenance mode, the compaction component 5 stops, and gaps are avoided from being generated by vibration when the kiln mud is drying at the bottom.

[0048] like Figure 2 As shown, a leveling component 6 is installed at the bottom of the second connecting column 33. The leveling component 6 contains a scraper 61, which is arc-shaped. This allows the leveling component 6 to level and increase the density of the sealing mud when the sealing mud spreading device is in the initial spreading mode; and when the sealing mud spreading device is in the maintenance mode, the leveling component 6 moves quickly to evenly level and cover the material, effectively saving maintenance time, improving work efficiency, reducing the possibility of oxygen infiltration, and increasing the fermentation success rate.

[0049] Furthermore, in order to make the vibration force more uniform and avoid local excessive vibration that could damage the mud structure used for sealing the kiln, the pressure roller 51 is equipped with a piezoelectric ceramic vibrating plate for vibration.
