[0001] This utility model belongs to the technical field of fermented bean curd fermentation, specifically relating to an automatic temperature and humidity controlled fermentation tank for fermented bean curd. Background Technology
[0002] In recent years, with the continuous advancement of food fermentation technology, fermented bean curd, as a traditional fermented soybean product, has increasingly stringent requirements for temperature and humidity control in its industrial production. In order to ensure that fermented bean curd can ferment well in different weather conditions, mechanical equipment for temperature and humidity control is usually integrated into the fermentation tank to ensure the successful fermentation of fermented bean curd.
[0003] Currently, when collecting fermented bean curd falling from the discharge pipe using an external collection box, the collection box is placed on the ground, and its inner bottom surface is far from the opening of the discharge pipe. When the fermented bean curd falls, it will be damaged due to the height of the fall, resulting in damage to the integrity of the fermented bean curd during the initial feeding process, which will affect the subsequent packaging operation of the fermented bean curd. Utility Model Content

A first mating groove is provided on the inner wall of the outer tube of the telescopic rod, and an adaptation groove is provided on the inner wall of the inner tube of the telescopic rod. The size of the adaptation groove is adapted to the size of the vertical rod of the limiting rod. A second mating groove is provided on the lower side of the outer tube of the telescopic rod, and a spring is sleeved on the surface of the telescopic rod.
[0007] As a preferred embodiment of this utility model, the limiting component includes two side plates fixedly connected to the surface of the placement plate. An elastic plate is fixedly connected to the side of the two side plates that are close to each other. The elastic plate is V-shaped and the tail end of the elastic plate is not connected to the side plate.
[0008] As a preferred embodiment of this utility model, the distance between the second arc plate and the placement plate is adapted to the distance between the vertical rod of the limiting rod and the matching groove, and the arc surfaces of the first arc plate and the second arc plate are in contact with the arc surfaces on both sides of the placement plate.

Detailed Implementation
[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1
[0016] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an automatic temperature and humidity controlled fermentation tank for fermenting fermented bean curd, including a slowing component. The fermentation tank body 10 is provided, and a discharge pipe 11 is installed on the lower side of the fermentation tank body 10. Two telescopic rods 12 are provided on the lower side of the fermentation tank body 10. A placement plate 13 is fixedly connected to the lower end of each of the two telescopic rods 12. An adjustment component 14 is provided between the telescopic rods 12 and the placement plate 13. A limiting component 15 is provided on the surface of the placement plate 13. A spring 16 for slowing down the placement plate 13 is sleeved on the surface of the telescopic rods 12.
[0017] The fermentation tank body 10 is equipped with temperature and humidity control devices. Temperature control is achieved by heating with internal coils and injecting cooling water. Dehumidification is achieved by injecting dry air into the tank. After the fermentation of the fermented bean curd is completed in the fermentation tank body 10, the valve on the surface of the discharge pipe 11 will be opened. At the same time, the operator can place the external collection frame on the surface of the placement plate 13 with the assistance of the adjustment component 14, which can improve the integrity of the collection of fermented bean curd by the collection frame, thus facilitating the discharge of fermented bean curd.
[0018] Furthermore, the adjustment assembly 14 includes an adjustment plate 141 slidably connected to the inner wall of the placement plate 13. A first arc plate 142 and a second arc plate 143 are fixedly connected to both ends of the adjustment plate 141, respectively. Two limiting rods 144 are fixedly connected to the surface of the adjustment plate 141. Both limiting rods 144 are L-shaped and are located inside the inner tube of the telescopic rod 12. A first docking groove 145 is provided on the inner wall of the outer tube of the telescopic rod 12. An adaptation groove 146 is provided on the inner wall of the inner tube of the telescopic rod 12. The size of the adaptation groove 146 is adapted to the size of the vertical rod of the limiting rod 144. A second docking groove 147 is provided on the lower side of the outer tube of the telescopic rod 12. The limiting component 15 includes two side plates 151 fixedly connected to the surface of the placement plate 13. An elastic plate 152 is fixedly connected to the side of the two side plates 151 that is close to each other. The elastic plate 152 is V-shaped and the tail end of the elastic plate 152 is not connected to the side plate 151.
[0019] When the external collection frame is placed on the surface of the placement plate 13, the elastic plate 152 can quickly limit the collection frame. Further adjusting the position of the limiting rod 144 can help the telescopic rod 12 release the limit, so that it can automatically slide down according to the weight of the fermented bean curd collected inside the collection frame, thereby completing the collection operation of the fermented bean curd.
[0020] Preferably, the distance between the second arc plate 143 and the placement plate 13 is matched with the distance between the vertical rod of the limiting rod 144 and the matching groove 146, and the arc surfaces of the first arc plate 142 and the second arc plate 143 are in contact with the arc surfaces on both sides of the placement plate 13. A roller 153 is rotatably connected to the tail end of the elastic plate 152, and the roller 153 abuts against the surface of the side plate 151.
[0021] It should be noted that the first arc plate 142 and the second arc plate 143 are in contact with the placement plate 13, which can increase the convenience of adjusting the position of the limit rod 144. When the adjustment plate cannot be pulled, it means that the adjustment has been made to the appropriate position, and no fine control is required from the operator. The roller 153 at the end of the elastic plate 152 can reduce the jamming when the elastic plate 152 expands and adjusts, thereby increasing the smoothness of the parts' operation.
[0022] During use, when the operator is feeding the fermented bean curd, the adjusting plate can be pulled outward from the limiting rod 144 at the circular hole position of the first arc plate 142. This allows the adjusting plate to cause the short side of the limiting rod 144 to disengage from the first docking groove 145. Simultaneously, as the second arc plate 143 abuts against the surface of the placement plate 13, the vertical rod of the limiting rod 144 is positioned within the inner wall of the fitting groove 146. The size of the fitting groove 146 matches the vertical rod of the limiting rod 144, increasing friction and preventing the limiting rod 144 from automatically shifting. Furthermore, the inner tube of the telescopic rod 12 disengages from the limiting position, allowing the operator to... Pull down the placement plate 13 and place the collection frame for collecting fermented bean curd between the two elastic plates 152 on the surface of the placement plate 13. As the collection frame is gradually pushed inward, it will be positioned directly below the discharge pipe 11. At the same time, the elastic plates 152 on both sides can clamp and limit the collection frame. The operator can then open the valve of the discharge pipe 11. At this time, the fermented bean curd inside the fermentation tank body 10 will be discharged downward and fall into the collection frame. Because the collection frame is close to the discharge port opening, the falling height of the fermented bean curd is reduced, thereby ensuring the integrity of the whole after the fermented bean curd is discharged. Furthermore, as more fermented bean curd is fed, due to the pull of spring 16, the placement plate 13 will not fall directly to the bottom position, but will slowly descend with the weight of the fermented bean curd. After the placement plate 13 reaches the bottom, the operator needs to slide the collection frame out. At this time, the operator can push the first arc plate 142 to make it fit against the arc surface of the placement plate 13. Simultaneously, the short side of the limiting rod 144 will enter the second docking groove 147, still limiting the telescopic rod 12, ensuring that the placement plate 13 will not fall after the collection frame is removed. Directly driven by spring 16 to reset, further closing the valve of discharge pipe 11, and then after the collection frame detaches from the surface of placement plate 13, the operator can pull the first arc plate 142 again to make the limiting rod 144 be in the position of the adapter groove 146. This telescopic rod 12 will disengage from the limit and will be automatically reset to the initial position by spring 16. The operator can then push the first arc plate 142 to fit against the surface of placement plate 13 to limit placement plate 13, so that placement plate 13 is in the opening of discharge pipe 11 during normal operation, which can prevent dust from entering the inside of discharge pipe 11. Example 2
[0023] Reference Figures 1-6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a warning component, including two external brackets 20 fixedly connected to the side wall of the placement plate 13. The surfaces of the two external brackets 20 are fixedly connected to metal plates 21. The inner walls of the two external brackets 20 are rotatably connected to rotating shafts 22. The surfaces of the rotating shafts 22 are fixedly connected to metal balls 23. A guide assembly 24 is provided between the external brackets 20 and the metal balls 23. The guide assembly 24 includes a slide plate 241 disposed on the inner wall of the external brackets 20. The surface of the slide plate 241 is fixedly connected to three guide blocks 242. The side wall of the slide plate 241 is fixedly connected to a series plate 243. The inner wall of the series plate 243 is fixedly connected to a sliding rod 244. The surface of the external brackets 20 is provided with a guide groove 245, and the sliding rod 244 is located inside the guide groove 245.
[0024] Specifically, when the placement plate 13 moves down to its limit position, the sliding plate 241 in contact with the ground will drive the guide block 242 to slide up, and guide it to hit the surface of the metal plate 21 by repeatedly contacting the metal ball 23, thereby achieving a warning effect and making it convenient for the standing operator to understand the collection progress of the fermented bean curd inside the collection box. Normally, the back of the sliding plate 241 is away from the external frame 20. When it moves up, the back of the sliding plate 241 will be guided by the sliding rod 244 inside the guide groove 245 to fit against the external frame 20 and move away from the position of the metal ball 23, so that it will not be obstructed when sliding down.
[0025] Preferably, the lower edge of the inclined surface of the three guide blocks 242 is parallel to the side of the rotating shaft 22 under normal conditions, and the guide blocks 242 are located under the metal ball 23.
[0026] It should be noted that when the guide block 242 moves upward, the bottom edge of the inclined plane will not be blocked by the rotating shaft 22, and it can fully contact the position of the metal ball 23 and guide its power towards the metal plate 21.
[0027] In use, after the collection box is placed on the upper side of the placement plate 13, as material is continuously discharged from the discharge pipe 11, the placement plate 13 will slowly move downwards. When the placement plate 13 touches the ground, it means that the collection box contains an appropriate amount of fermented bean curd. Before the placement plate 13 touches the ground, the sliding plate 241 can make contact with the ground in advance. At this time, the sliding plate 241 will be pushed upwards, simultaneously driving the guide block 242 to slide upwards. When the guide block 242 slides upwards, it will guide the metal ball 23 to slide and deflect towards the metal plate 21, and generate a prompt sound by impact, which can remind the operator that the collection box is about to be filled with an appropriate amount of fermented bean curd. The sequential action of the guide block 242 causes the metal ball 23 to strike the metal plate 21 multiple times, thereby prompting the operator to close the valve of the discharge pipe 11. Subsequently, the operator can remove the collection frame from the surface of the placement plate 13. Furthermore, when the placement plate 13 is reset to its initial position by the spring 16, the slide plate 241 can slide down along the guide groove 245 under the force of gravity. At this time, the guide block 242 is far away from the metal ball 23 and can slide down smoothly without obstruction. Guided by the guide groove 245, when the slide plate 241 moves upward, the guide block 242 is still under the metal ball 23.
[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
