Description

Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to a device for maintaining the mud in brewing cellars. Background Technology

[0002] Fermentation pits are the main containers for fermenting liquor products. The pit mud at the bottom of the pit contains various microorganisms, and the quantity, type, and activity of these microorganisms directly affect the quality of the liquor. Producing high-quality liquor begins with ensuring the quality of the pit mud. In actual production, after long-term and repeated use, the pit mud may experience problems such as deterioration of microbial activity, crystallization, and compaction, thus affecting microbial fermentation and reducing the quality of the liquor. To address this issue, Chinese Patent Publication No. CN 218232315 U discloses "A Pit Mud Control Device for Baijiu Fermentation Pit." This device has three layers of cultivation tubes with nozzles installed at different heights on one side wall of the pit. Nutrient solution is sprayed onto the pit mud at different depths using the nozzles, and then a turbine-shaped stirring roller is used to agitate the pit mud, achieving a balanced distribution of the nutrient solution within the pit mud. However, this device has significant drawbacks: First, the nutrient spray nozzles are located on one side of the fermentation pit, resulting in areas closer to the nozzles receiving more nutrient solution, while areas farther away receive less, or even none at all, despite the stirring rollers. Second, the nutrient solution sprayed from the nozzles comes into extensive contact with air, reducing its activity and affecting the preservation of the fermentation pit mud. Third, its complex structure makes it impractical. Therefore, most manufacturers still use the traditional method of manually punching holes in the fermentation pit mud for preservation. This method involves manually punching holes in the mud and quickly pouring nutrient solution into them. Manual punching has several drawbacks: First, it cannot guarantee consistent hole depth, spacing, and density. Second, although the nutrient solution is poured quickly into the holes, it still comes into extensive contact with air before entering, affecting its activity. Both of these directly impact the preservation of the fermentation pit mud and the quality of the wine. Furthermore, manual punching is inefficient, labor-intensive, and has a long production cycle, reducing economic benefits. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies for maintaining cellar mud. Combining the ancient method of tying rods, it provides a cellar mud maintenance device that is simple in structure, highly practical, easy to drill holes, with uniform hole depth, spacing, and density, rapid hole drilling, low labor intensity, and ensures the activity of the nutrient solution before it comes into contact with air before injection, thus guaranteeing the cellar mud maintenance effect and the quality of wine products, and improving economic benefits.

[0004] The purpose of this utility model can be achieved. This utility model's pit mud curing device includes a device body and a push-pull handle for the device body. The device body is characterized by: the device body being a rectangular tabletop shape; a quadrangular prism-shaped sliding structural leg is fixed to each of the four corners of the device body; a groove is symmetrically formed on the corresponding surfaces of the two front sliding structural legs, following the height of the sliding structural legs; the two grooves are slidably connected to a slider; another slider is also slidably connected to the two rear sliding structural legs; an internal threaded sleeve is fixed to the upper and lower surfaces of the center of each slider; the two internal threaded sleeves are threadedly connected to a lead screw; the lead screw is fixed between the device body and the two sliding structural legs via bearings. On the connecting cross brace, a driven pulley is provided at the upper end of the lead screw. A motor is installed at the center of the device body. The motor passes through the main shaft below the device body and is provided with two driving pulleys. Each driving pulley is connected to the driven pulleys of the front and rear lead screws respectively through its own transmission belt. The two sliders are connected to a hollow lifting platform. A nutrient solution tank and a liquid pump are provided in the cavity of the lifting platform. The nutrient solution tank is connected to the liquid pump through a low-pressure pipe. The liquid pump is connected to the hollow pipe through a high-pressure pipe. The hollow pipe is located at the center below the lifting platform. A nutrient solution distribution plate is connected to the bottom end of the hollow pipe. Several nutrient solution injection heads are connected below the nutrient solution distribution plate.

[0005] The present invention relates to a cellar mud curing device, wherein each end of the slider has a sliding tongue, and the sliding tongue enters the sliding groove of the sliding structural leg and slides in connection with the sliding structural leg.

[0006] In this utility model, the cellar mud curing device, the motor is a bidirectional motor, which drives the lead screw to rotate in two directions (forward and reverse) via a transmission belt. The lead screw drives the slider to move in two directions (up and down) via an internal threaded sleeve. The slider drives the lifting platform to move in two trajectories (up and down).

[0007] In this utility model of a pit mud curing device, the lifting platform moves the hollow tube and nutrient solution distribution plate downwards to inject nutrient solution into the pit mud by inserting the nutrient solution injection head into the pit mud, and the lifting platform moves the nutrient solution distribution plate and nutrient solution injection head away from the pit mud to stop injecting nutrient solution into the pit mud.

[0008] The present invention relates to a cellar mud curing device, wherein the two ends of the push-pull handle are respectively fixed to two sliding structural legs by a connecting rod, and the lower end of the sliding structural legs is equipped with universal wheels. The cellar mud curing device moves by pushing and pulling the handle and universal wheels, and straddling the two sides of the cellar wall is the working state of the cellar mud curing device.

[0009] This utility model of pit mud curing device differs from existing technologies in that it includes a rectangular device body. Each of the four corners of the device body has a sliding structural leg with a groove. Two opposing grooves share a common slider, which is connected to a lead screw via an internal threaded sleeve. Both sliders are connected to a lifting platform containing a nutrient solution tank and a liquid pump. Both lead screws are connected to a motor via a transmission belt. The motor drives the lifting platform downwards through the lead screws and sliders, while the liquid pump injects nutrient solution into the pit mud through a nutrient solution injection head. Injection stops when the nutrient solution injection head moves upwards and is removed from the pit mud. This utility model of pit mud curing device incorporates the ancient method of piercing holes. The piercing depth, spacing, and density are consistent throughout the pit mud, ensuring uniform nutrient solution injection. The nutrient solution is kept away from air, guaranteeing its activity; both factors contribute to improved pit mud curing effectiveness. Using this utility model of pit mud curing device results in high work efficiency, reduced labor intensity and production cycle, and improved economic benefits.
