TECHNICAL FIELD
[0001] The utility model relates to fermentation equipment technical field, concretely relates to a pickled Chinese cabbage fermentation tank. BACKGROUND
[0002] The pickled Chinese cabbage fermentation tank, also known as a fermentation tank, is a facility used for large-scale production of pickled Chinese cabbage. It converts fresh vegetables (usually Chinese cabbage, cabbage, and cowpea) into pickled Chinese cabbage with unique flavor through the action of microorganisms. The fermentation tank is usually made of concrete, stainless steel, or food-grade plastic to ensure corrosion resistance and hygiene. Depending on the production scale, the size of the fermentation tank can range from a few cubic meters to tens or even hundreds of cubic meters. During fermentation, fresh Chinese cabbage or other suitable vegetables for making pickled Chinese cabbage are selected, washed clean, and cut into appropriate sizes. The cut vegetables are placed in the fermentation tank, evenly sprinkled with salt, and gently rubbed by hand to ensure uniform distribution of salt. A weight is placed on the vegetables or a mechanical device is used to compact them, expelling air. Then a layer of plastic film is covered on the surface of the entire fermentation tank, and a layer of clean and impurity-free sand is covered on the plastic film. The weight of the sand can exert pressure on the vegetables in the fermentation tank, ensuring that the vegetables are completely immersed in brine, which helps to expel air, create an anaerobic environment, and promote the growth and fermentation of lactic acid bacteria. At the same time, the sand has a certain heat preservation effect, which can help maintain the temperature stability in the fermentation tank. Currently, the sand covering on the fermentation tank is usually done manually using a shovel or rake to level and compact the sand. However, this method of covering sand consumes a lot of manual labor and the surface of the sand is not flat when compacted with a shovel or rake, which cannot guarantee the uniformity of sand covering. This leads to uneven pressure distribution and affects the fermentation effect. SUMMARY

One of the sliding blocks 13 is fixedly connected to a motor 7, and the output shaft of the motor 7 is fixedly connected to the central shaft of the extrusion roller 11; the opposite two sides of the movable frame 5 are rotatably connected to horizontally arranged rotating shafts 3, the two ends of each rotating shaft 3 are rotatably connected to positioning blocks 1, and the positioning blocks 1 are fixedly connected to the upper surface of the movable frame 5; two transmission gears 2 are coaxially fixedly connected to each rotating shaft 3, and the same annular transmission chain 4 is sleeved on the two transmission gears 2 on the different rotating shafts 3; one transmission chain 4 is fixedly connected to one sliding plate, and when the transmission chain 4 moves, the sliding block 13 is driven to move along the sliding direction of the sliding plate; the movable frame 5 is fixedly connected to a motor 9, and the output shaft of the motor 9 is coaxially fixedly connected to one of the rotating shafts 3.
[0021] The movable frame 5 is fixedly connected to a controller, the four electric lifting rods, the motor 7, the motor 9 and the two infrared sensors are electrically connected to the controller through cables.
[0022] The specific implementation process is as follows:
[0023] After the vegetables to be pickled are placed in the pool body 8 and the plastic film is laid, sand is poured on the surface of the plastic film, and then the four electric lifting rods 6 are simultaneously started to control the movement of the movable frame 5, the sliding block 13 and the extrusion roller 11. When the extrusion roller 11 moves to the appropriate height, the controller stops the operation of the electric lifting rod 6. At this time, the controller simultaneously starts the motor one 7 and the motor two 9. Since the motor one 7 is fixedly connected to the sliding block 13, the motor one 7 is used to drive the extrusion roller 11 to rotate, the output shaft of the motor two 9 is coaxially fixedly connected to one of the shafts 3, two transmission gears 2 are coaxially fixedly connected to the shaft 3, and the two transmission gears 2 on the shaft 3 are connected to the two transmission gears 2 on the other shaft 3 through the ring chain.

When the extrusion roller 11 rotates, the sand on the plastic film is extruded and compacted. When the extrusion roller 11 moves in the horizontal direction, the accumulated sand is pushed to move on the plastic film, filling the gaps in the sand or areas where the sand is not thick enough. When the sliding block 13 drives the extrusion roller 11 to move to the end of the sliding direction, the infrared sensor detects that the extrusion roller 11 has moved to the end of the sliding direction, and then the infrared sensor transmits the monitoring signal to the controller. Then the controller stops the operation of the motor two 9, and then reversely starts the motor two 9 to make the motor rotate in the opposite direction, so that the extrusion roller 11 moves in the opposite direction. Thus, the extrusion roller 11 moves back and forth above the pool body 8, which can compact the sand several times to ensure the compacting effect. Moreover, during the reciprocating movement, the push plate 10 can first push the accumulated sand to be flat, so as to facilitate the compaction of the extrusion roller 11.
