Description

Technical Field

[0001] The invention relates to the technical field of biological agriculture, and more specifically to a process for continuously and rapidly producing edible fungus sticks. Background Art

[0002] The edible mushroom stick is an indispensable and important medium in the process of artificial cultivation of edible fungi. It carries the culture medium, carefully creates a suitable environment for the edible fungi to thrive and provides sufficient nutrition. When making mushroom sticks, specific culture media, such as sawdust, cottonseed hulls, corn cobs, etc., need to be selected and fully mixed in a scientific and reasonable proportion. At the same time, auxiliary materials such as bran, gypsum, and lime need to be added to further optimize the nutritional structure of the culture medium. After a series of rigorous and critical processes such as bagging, strict sterilization, and precise inoculation, the mushroom stick is completed. Functionally, the mushroom stick is like an exquisite "micro-culture medium", which provides an ideal environment and inexhaustible nutrients for the growth and reproduction of edible fungi mycelium, and helps the healthy growth of edible fungi.

[0003] In the process of making edible mushroom sticks, in order to improve production efficiency and quality, various mechanical devices are often used to assist the work of each link. These include raw material processing equipment, bagging equipment, sterilization equipment, and inoculation equipment. In the raw material processing equipment, the mixing device plays a vital role. It can fully mix the main materials such as sawdust, cottonseed hulls, corn cobs with auxiliary materials such as bran, gypsum, lime, and appropriate amount of water in a precise proportion to ensure that the nutrients of the culture medium are evenly distributed and provide a high-quality matrix for the growth of edible mushroom mycelium.

[0004] After the mixing is completed, the raw materials will be transported to the bagging equipment in an orderly manner through the conveying device to complete the bagging process. However, with the rapid development of science and technology and the continuous innovation of technology, many manufacturers have now innovated and transformed the equipment, cleverly integrating the mixing device with the bagging equipment to form a mixing and bagging machine;

[0005] This all-in-one mixing and bagging machine has significant advantages. On the one hand, it effectively reduces the process steps, greatly shortens the production cycle, makes the entire mushroom stick production process more compact and efficient, and significantly improves production efficiency. On the other hand, since the material transfer in the intermediate links is reduced, the risk of contamination of the culture medium is reduced, and the quality stability of the mushroom sticks is guaranteed. In addition, the all-in-one machine also reduces the equipment footprint to a certain extent, reduces labor costs, and achieves optimal allocation of resources, providing strong support for the large-scale and industrialized production of edible fungi.

[0006] Taking actual patent technology as an example, it can better reflect the innovation and progress of today's edible mushroom stick production equipment. For example, the Chinese patent with application number 202120332431.3 discloses an edible mushroom stick mixing and bagging integrated device. The device includes a frame, a loading device, a mixer, a material receiving device, and a controller;

[0007] The above equipment creatively combines the functions of mixing and bagging. During operation, the mixer fully plays its role. After mixing various raw materials, the loading device quickly takes over and directly bags the mixed materials through the bagging device. This ingenious design greatly reduces the material transfer time in the intermediate links, significantly shortens the production time of edible mushroom sticks, and greatly improves production efficiency.

[0008] However, a closer look at the mixer in the edible mushroom stick mixing and bagging integrated device disclosed in the Chinese patent application number 202120332431.3 shows that the mixer has a funnel-shaped component at the top and a straight cylinder structure at the bottom. The mixing component is only installed inside the straight cylinder;

[0009] According to the principle of the nut effect, when the stirring component rotates, it will inevitably cause the material to vibrate as a whole. Under the action of this vibration, small particles in the material will gradually move downward, while large particles will move upward, resulting in obvious stratification of the material;

[0010] This material stratification phenomenon will bring many adverse effects. On the one hand, the nutrient distribution of the stratified material is uneven. When it is bagged to make edible mushroom sticks, there may be differences in the nutrient supply of different parts of the mushroom stick, affecting the uniform growth of edible mushroom mycelium, resulting in inconsistent mycelium growth rate, slow growth or even stagnation in some areas, and reducing the yield and quality of edible mushrooms. On the other hand, during the bagging process, the stratified material may cause inconsistent bagging tightness due to uneven particle distribution, affecting the physical structure stability of the mushroom stick, and prone to breakage, contamination and other problems in the subsequent cultivation process, increasing production costs and production risks. Therefore, this material stratification phenomenon will have a significant negative effect on the production of edible mushroom sticks, and it is urgent to improve and optimize.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Embodiment 1

[0053] In the prior art mixer, according to the principle of the nut effect, it can be known that when the stirring part rotates, it will inevitably cause the whole material to vibrate. Under the action of this vibration, small particles in the material will gradually move downward, while large particles will move upward, resulting in obvious stratification of the material;

[0054] This material stratification phenomenon will bring many adverse effects. On the one hand, the nutrient distribution of the layered material is uneven. When it is bagged to make edible mushroom sticks, there may be differences in the nutrient supply of different parts of the sticks, affecting the uniform growth of edible mushroom mycelium, resulting in inconsistent mycelium growth rates, slow growth or even stagnation in some areas, and reducing the yield and quality of edible mushrooms. On the other hand, during the bagging process, the layered material may cause inconsistent bagging tightness due to uneven particle distribution, affecting the physical structure stability of the mushroom stick, and is prone to breakage, contamination and other problems in the subsequent cultivation process, increasing production costs and production risks. Therefore, this material stratification phenomenon will have a significant negative effect on the production of edible mushroom sticks, and this embodiment is specially invented to solve the above problems.

[0055] See also Figures 1 to 11 The present invention provides a technical solution: a continuous and rapid mushroom stick production process for edible mushrooms, the production process comprising the following steps:

[0056] S1 Ingredients: weigh mulberry branch scraps, bran, xylitol residue, corn cobs, lotus seed shells, gypsum powder, magnesium sulfate and water by weight;

[0057] S2 Mixing: Put the above ingredients into a mixing and bagging machine and mix them evenly to obtain a mixed matrix for later use;

[0058] S3 bagging: put the mixed matrix into a plastic bag, tie the bag tightly, and make mushroom sticks for later use;

[0059] S4 sterilization: The above-mentioned bacteria sticks are placed in the sterilization chamber for sterilization, and the bacteria sticks are neatly stacked in the sterilization cart. Temperature and pressure sensors are set in the sterilization cart, and the sterilization cart is pushed into the sterilization chamber. First, turn on the air circulation system of the sterilization chamber for 15 minutes to exhaust the cold air in the room, and then increase the temperature of the sterilization chamber to 100°C at a heating rate of 2°C / minute, and maintain it for 2 hours for pre-sterilization to kill some microorganisms that are not resistant to high temperatures. Then continue to increase the temperature to 121°C at a rate of 1°C / minute, and the pressure reaches 0.105MPa. Maintain this state for 1.5 hours for thorough sterilization. Monitor the temperature and pressure data in real time during the sterilization process to ensure stable sterilization conditions. After the sterilization is completed, slowly release the pressure, and reduce the temperature to 80°C at a cooling rate of 1°C / minute. After a period of natural cooling, take out the bacteria sticks;

[0060] S5 Cooling: After sterilization, place the bacteria sticks in a sterile room to cool;

[0061] S6 Inoculation: After the mushroom sticks are cooled to room temperature, the mushroom liquid spawn in the liquid fermentation tank is used to inoculate the mushroom sticks. After the inoculation, the bag mouth is immediately plugged with clean cotton to cultivate the mushrooms, and the inoculated mushroom sticks are obtained;

[0062] S7 Cultivation: The prepared mushroom spawn sticks are transported to the cultivation room, and the production of mushroom spawn sticks is completed after the mycelium cultivation, mushroom management and harvesting processes;

[0063] The mixing and bagging machine comprises a mixing part 1 and a bagging part 2 arranged at an opening directly below the mixing part 1. A plurality of main stirring plates 7 capable of synchronous rotation are arranged from front to back in the mixing part 1. A plurality of auxiliary stirring plates 8 (such as a plurality of auxiliary stirring plates 8) capable of forming an inclined surface on one side are evenly arranged in the middle of the main stirring plate 7 along its length direction. Figure 3 As shown, when the auxiliary stirring plate 8 is in working state, the same side surfaces of multiple auxiliary stirring plates 8 are spliced ​​together to form an inclined plate structure with an inclined surface), one side of the auxiliary stirring plate 8 is provided with a push plate 10 that can slide into the auxiliary stirring plate 8, and one end of the auxiliary stirring plate 8 is provided with a pressing component that can provide power to the push plate 10 adapted thereto.

[0064] The front end of the bagging component 2 is fixedly connected to the bottom end of the mixing component 1, and the feed port at the front end of the bagging component 2 is connected to the discharge port of the mixing component 1. Therefore, when the mixing component 1 has fully mixed the material, the material can be directly transported to the feed port of the bagging component 2 through its discharge port. In addition, a material receiving component is provided at the rear of the bagging component 2. The structure of the material receiving component is exactly the same as that disclosed in the Chinese patent application number 202120332431.3, and its working principle is also the same. To avoid repetition, it will not be elaborated here. Similarly, the working principle of the bagging component 2 is the same as that disclosed in the above-mentioned patent, so no further explanation is given. A support frame for supporting the mixing component 1 is arranged directly below the mixing component 1. The support frame plays a role in stabilizing the mixing component 1 and ensuring that it maintains a stable working state during the mixing process to avoid affecting the mixing effect due to shaking or instability. The front end and the rear end of the support frame are fixedly connected to the front end and the rear end of the mixing component 1 respectively. This connection method further enhances the connection strength and stability between the support frame and the mixing component 1, and ensures that the support frame reliably supports the mixing component 1. At the same time, a driving motor is arranged at the rear end of the support frame, and the output shaft of the driving motor is arranged on the driving shaft 6, so that when the driving motor is working, the driving shaft 6 can be driven to rotate.

[0065] The mixing component 1 includes a mixing chamber arranged on a support frame, in which a driving shaft 6 is rotatably connected, and a plurality of main stirring plates 7 are fixedly connected to the driving shaft 6. The main stirring plates 7 are installed on the driving shaft 6 in the form of multiple groups, each group including 4 main stirring plates 7. In the circumferential direction, the angle between two adjacent main stirring plates 7 is 90 degrees. For specific settings, please refer to Figure 7 The discharge port is opened at the bottom of the mixing bin, and a partition plate 4 is slidably connected to the bottom of the mixing bin to close or open the discharge port. A cylinder 3 is arranged at the front end of the support frame, and a driving rod at the rear end of the cylinder 3 is fixedly connected to an auxiliary driving plate 5, and the top end of the auxiliary driving plate 5 is fixedly connected to the partition plate 4;

[0066] The cylinder 3 is a key power component. When the cylinder 3 is started and put into work, the power generated by it will drive the auxiliary driving plate 5 to perform translational movement in the forward and backward directions. The auxiliary driving plate 5 and the partition plate 4 form a linkage relationship through a specific mechanical connection, so when the auxiliary driving plate 5 moves forward and backward, the partition plate 4 will be driven to move synchronously. When the partition plate 4 moves forward, it is like opening a gate, and the discharge port is gradually opened. With the opening of the discharge port, the material channel between the discharge port and the feed port of the bagging component 2 is opened, and the two are connected. The material can flow smoothly from the discharge port to the feed port of the bagging component 2. When the partition plate 4 moves backward, it is like closing a barrier, and the discharge port will be gradually closed. After the discharge port is closed, the material channel between it and the feed port of the bagging component 2 is cut off, and the two are in a disconnected state. The material can no longer flow from the discharge port to the feed port of the bagging component 2.

[0067] One side of each auxiliary stirring plate 8 is an inclined surface, and the middle part of the front and rear sides of the auxiliary stirring plate 8 is fixedly connected with an auxiliary slide plate 17, and the auxiliary slide plate 17 is slidably connected in the main stirring plate 7, and one side of the auxiliary slide plate 17 is fixedly connected with a third spring 18, and the end of the third spring 18 away from the auxiliary slide plate 17 is fixedly connected to the main stirring plate 7.

[0068] The main stirring plate 7 is in a U-shape, and a plurality of first chutes 16 are provided on the inner side of the main stirring plate 7 along its length direction, and a second chute 21 is provided on one side of each first chute 16, and a plurality of auxiliary slide plates 17 respectively penetrate the first chutes 16 adapted thereto at one end away from the auxiliary stirring plate 8 and extend into the second chutes 21, and a second blocking block 19 is provided on the side of the second chutes 21 away from the auxiliary stirring plate 8, and the farther the second blocking block 19 is from the drive shaft 6, the closer the second blocking block 19 is to the initial position of the auxiliary slide plate 17;

[0069] Thanks to the ingenious arrangement of the second blocking block 19, the maximum movement distance of the auxiliary stirring plate 8 on the main stirring plate 7 can be precisely limited. In this way, when multiple auxiliary stirring plates 8 move to the limit position on the main stirring plate 7, they will be orderly combined on the main stirring plate 7, and finally form an inclined plate with a specific inclination angle;

[0070] At the same time, the initial length of the third spring 18 on each auxiliary slide 17 is the same, but the elastic potential energy generated by it is different (according to Hooke's law, the stiffness coefficients of the springs at different positions are different, for example, due to factors such as manufacturing process and material properties, so the elastic potential energy generated during the working process can be different). It is just that when the auxiliary slide 17 contacts the second blocking block 19, the elastic potential energy generated by each third spring 18 on the auxiliary slide 17 is the same. Therefore, when each auxiliary stirring plate 8 is subjected to the same blocking force, the auxiliary stirring plate 8 will move with the auxiliary slide 17 to a specific position and contact the second blocking block 19, thereby prompting multiple auxiliary stirring plates 8 to form a plate with an inclined surface.

[0071] Baffles 9 are slidably connected to both ends of the first chute 16, and the opposite ends of the two baffles 9 are fixedly connected to the auxiliary slide plate 17. Since the distances moved by the auxiliary stirring plate 8 during operation are different, the lengths of the baffles 9 are not of uniform specifications. In order to make the baffles 9 perfectly adapt to the different moving distances of the auxiliary stirring plate 8, baffles 9 of different lengths are specially set to ensure the effective performance of their functions. At the same time, through the setting of the baffles 9, the exposed opening of the second chute 21 can be covered, thereby preventing materials from entering the second chute 21.

[0072] In the material stirring process, the auxiliary stirring plate 8 plays a key role. When the main stirring plate 7 starts to rotate along with the driving shaft 6, the auxiliary stirring plate 8 starts to mix and stir the materials synchronously. The auxiliary stirring plate 8 is provided with a unique inclined surface. When this inclined surface contacts the material, the material will generate a blocking force on the auxiliary stirring plate 8. Based on this blocking force, the auxiliary stirring plate 8 on each main stirring plate 7 will be displaced on the main stirring plate 7.

[0073] When the auxiliary stirring plate 8 moves to the maximum position, multiple auxiliary stirring plates 8 on the same main stirring plate 7 will be combined into an inclined plate with an inclined surface. When stirring materials, this inclined plate can use its own inclination angle to lift the granular materials at the bottom of the mixing bin upward along the inclined surface, thereby promoting the material to form a circulation movement from the bottom to the top in the mixing bin. This movement mode effectively avoids excessive accumulation of materials at the bottom, which is greatly beneficial to the uniform distribution of materials in the entire mixing bin space. At the same time, a temporary chute structure is formed between the inclined plate and the main stirring plate 7, which can more efficiently lift the bottom material and fully mix it with the upper material.

[0074] At the same time, when the auxiliary stirring plate 8 is at the initial position on the main stirring plate 7, an inclined groove is formed between two adjacent auxiliary stirring plates 8. This inclined groove can press the materials at the top downward, further enhancing the mutual mixing effect between the materials, significantly improving the mixing effect of the materials, effectively eliminating the possible stratification of the materials, and ensuring the uniformity and stability of the material mixing.

[0075] Embodiment 2

[0076] In the above embodiment, the stirring scheme has indeed successfully overcome the problem of material stratification, greatly promoted the uniform mixing of materials, and achieved remarkable results. However, it should not be ignored that due to the characteristics of the materials themselves, during the stirring process, the friction between the materials and between the materials and the stirring components will inevitably produce debris. These debris are easily accumulated at the bottom of the stirring container due to the influence of gravity and stirring motion.

[0077] For mushroom stick production, the accumulation of debris at the bottom will bring a series of thorny problems. First, it will change the original ratio of the materials. These debris may come from materials of different ingredients, and the accumulation will cause an imbalance in the composition of the bottom materials. When participating in the production of mushroom sticks, the nutritional components of various parts of the mushroom sticks will be inconsistent, affecting the growth of mycelium. For example, if too much sawdust debris is accumulated, the air permeability and carbon source content of the mushroom stick will change, causing the mycelium to grow slowly or even stunted. Second, a large amount of debris accumulates at the bottom, which is easy to breed miscellaneous bacteria. The humid environment and rich organic matter provide ideal living conditions for miscellaneous bacteria. In the subsequent mushroom stick production, miscellaneous bacteria may contaminate the mushroom sticks, reduce the yield of the mushroom sticks, and cause the quality of mushrooms to decline, or even fail to produce mushrooms, seriously affecting the economic benefits. Third, the accumulation of debris may also interfere with the normal operation of the stirring equipment, resulting in uneven stirring, further affecting the quality stability of the mushroom sticks. This embodiment is specially invented to solve the above problems.

[0078] See also Figures 1 to 11 On the basis of the above embodiment, the adopted technical solution includes a limiting groove being opened on one end of the auxiliary stirring plate 8 close to the driving shaft 6, and a plurality of push plates 10 are respectively slidably connected in the corresponding limiting grooves, and a plurality of first springs 11 with one end each arranged on the push plate 10 are fixedly connected to one side of the limiting groove.

[0079] The end of the auxiliary stirring plate 8 away from the driving shaft 6 is provided with a first blocking block 13 capable of causing the push plate 10 to slide into the limiting groove, wherein the end of the first blocking block 13 away from the auxiliary stirring plate 8 is clamped on the push plate 10, and the push plate 10 here is not on itself, but on its adjacent auxiliary stirring plate 8;

[0080] When the auxiliary stirring plate 8 slides on the main stirring plate 7, the first blocking block 13 installed on the auxiliary stirring plate 8 responds quickly and plays a key role. It pushes the matching push plate 10 to slide smoothly into the auxiliary stirring plate 8 in a precise mechanical linkage manner. With the displacement of the push plate 10, the limit groove on the auxiliary stirring plate 8 is instantly transformed into a temporary storage space with unique functions, just like a delicate "debris collection bin".

[0081] In the dynamic process of material stirring, the auxiliary stirring plate 8 can efficiently and accurately collect part of the debris generated by stirring by virtue of this temporary storage space. These debris are temporarily stored therein, effectively avoiding their large-scale accumulation at the bottom of the material, and curbing a series of problems that may be caused by the accumulation of debris from the source. Therefore, the risk of debris gathering at the bottom to form a humid, organic-rich environment, thereby breeding miscellaneous bacteria, is greatly reduced, effectively ensuring the stable operation of the stirring equipment, and laying a solid foundation for improving the quality and yield rate of mushroom stick production.

[0082] When the auxiliary stirring plate 8 completes the stirring action and loses contact with the material, the pre-set first spring 11 begins to work. The first spring 11 quickly pushes the push plate 10 outward and resets with its precisely adjusted elastic potential energy. As the push plate 10 resets, the debris stored in the limit groove is released and re-mixed into the material. These debris are evenly distributed in the material, further promoting the uniformity of material stirring, effectively preventing quality differences in the material due to uneven distribution of debris, providing a strong guarantee for the high-quality production of mushroom sticks, and greatly optimizing the material mixing process.

[0083] Embodiment 3

[0084] In the above embodiment, the problem of debris accumulation at the bottom of the material was successfully solved through sophisticated structural design and coordinated mechanical linkage. This technological breakthrough effectively avoids the humid, organic-rich environment caused by the accumulation of debris, thereby eliminating the risk of bacteria breeding, ensuring the stable operation of the mixing equipment and laying a solid foundation for achieving high quality and high yield of mushroom stick production.

[0085] However, due to the characteristics of the materials themselves, agglomeration will still occur during the mixing process. The raw materials of mushroom sticks are mainly composed of a variety of organic substances such as sawdust, bran, cottonseed hulls, etc., which are inherently water-absorbent. If the water added during mixing is not evenly dispersed, it will easily lead to excessive local moisture. Moreover, the polysaccharides, proteins and other components in these raw materials will undergo physical and chemical reactions under the action of water, increasing the viscosity between particles, and then sticking to each other and agglomerating. In addition, the uneven distribution of mechanical force during the stirring process may also cause the material to aggregate and agglomerate in areas with higher humidity.

[0086] The agglomeration phenomenon will cause a series of negative effects. First, agglomeration seriously affects the mixing uniformity of the materials, causing an imbalance in the nutrients in various parts of the mushroom stick and interfering with the normal growth of the mycelium. For example, in the agglomeration area, excessive enrichment of nutrients may cause the mycelium to grow wildly and consume nutrients excessively; while other areas will cause mycelium to grow slowly and develop poorly due to lack of nutrients. Secondly, agglomeration will hinder the subsequent bagging process, resulting in poor bagging and even blocking the bagging equipment, greatly reducing production efficiency. Furthermore, the air permeability of the agglomerated material becomes poor, which is not conducive to the aerobic respiration of the mycelium and may inhibit the growth of the mycelium. In severe cases, anaerobic fermentation will be triggered, producing harmful gases, causing the mushroom stick to deteriorate, and seriously reducing the yield and quality of the mushroom stick. This embodiment is specially invented to solve the above problems.

[0087] See also Figures 1 to 11 On the basis of the above embodiment, the technical solution adopted includes that the pressing component includes a limit column 23 slidably connected to the auxiliary stirring plate 8, and the middle part of the limit column 23 is rotatably connected to the blocking ring 12, the end of the first blocking block 13 close to the limit column 23 is fixedly connected to the blocking ring 12, and the bottom end of the blocking ring 12 is fixedly connected to an auxiliary push rod 14 with one end capable of contacting the push plate 10;

[0088] One end of the second blocking block 19 away from the auxiliary stirring plate 8 is slidably connected to the inner side of the second slide groove 21, and one side of the second blocking block 19 away from the auxiliary slide plate 17 is fixedly connected to the fourth spring 20, and one end of the fourth spring 20 away from the second blocking block 19 is fixedly connected to the auxiliary pad 29;

[0089] The length of each auxiliary pad 29 is precisely set according to the distance between the auxiliary stirring plate 8 and the drive shaft 6. When the auxiliary stirring plate 8 is far away from the drive shaft 6, the auxiliary pad 29 adapted thereto is shorter; conversely, when the auxiliary stirring plate 8 is closer to the drive shaft 6, the length of the auxiliary pad 29 is longer. This is because on the same main stirring plate 7, different auxiliary stirring plates 8 have different initial contact positions with the second blocking block 19, while the length of the fourth spring 20 remains the same. In order to ensure that each auxiliary stirring plate 8 can maintain a stable working state and appropriate mechanical properties at different moving distances, the length of the auxiliary pad 29 must be determined according to the actual moving distance of the auxiliary stirring plate 8.

[0090] A mounting groove is provided on the side of the auxiliary stirring plate 8 away from the driving shaft 6, and the blocking ring 12 is slidably connected in the mounting groove, and one end of the blocking ring 12 is fixedly connected to an adapter block 28 slidably connected in the auxiliary stirring plate 8, and a limiting sliding groove adapted to the adapter block 28 is provided on the inner side of the mounting groove, and a second spring 15 is fixedly connected to the side of the auxiliary push rod 14 close to the driving shaft 6, and the side of the second spring 15 away from the auxiliary push rod 14 is fixedly connected to one side in the mounting groove, and one end of the first blocking block 13 away from the blocking ring 12 is clamped in the push plate 10;

[0091] An arc-shaped limit barrel 24 is fixedly connected to the middle of the limit column 23, an auxiliary connecting plate 27 is fixedly connected to the inner circumference of the blocking ring 12, an arc-shaped limit block 22 is slidably connected to the open end of the arc-shaped limit barrel 24, a tension spring 25 is arranged at one end of the arc-shaped limit block 22 close to the arc-shaped limit barrel 24, an end of the tension spring 25 away from the arc-shaped limit block 22 is fixedly connected to the inner side surface of the arc-shaped limit barrel 24, and a fifth spring 26 with one end arranged on the auxiliary connecting plate 27 is fixedly connected to the side of the arc-shaped limit block 22 away from the arc-shaped limit barrel 24;

[0092] When from Fig. 9 From a viewing angle, when the first blocking block 13 is subjected to a counterclockwise thrust, the first blocking block 13 will quickly convert the thrust into a driving force for the blocking ring 12 due to the close mechanical connection and ingenious structural design between the two, so that the blocking ring 12 can rotate precisely in the counterclockwise direction. During the rotation of the blocking ring 12, the auxiliary connecting plate 27 connected to the blocking ring 12 will be displaced synchronously, thereby exerting a squeezing force on the fifth spring 26, causing the fifth spring 26 to undergo elastic deformation.

[0093] When the first blocking block 13 is subjected to a clockwise force, the first blocking block 13 will drive the blocking ring 12 to rotate smoothly in the clockwise direction based on a reliable mechanical linkage mechanism. The force generated by this rotation will be transmitted through a series of precise mechanical structures and finally act on the arc-shaped limit block 22. Under the action of the force, the arc-shaped limit block 22 will slide smoothly on the arc-shaped limit barrel 24 adapted thereto. As the arc-shaped limit block 22 slides, it will generate a pulling force on the tension spring 25, causing the tension spring 25 to stretch.

[0094] When the main stirring plate 7 drives the auxiliary stirring plate 8 to rotate in the mixing bin with the power of the driving shaft 6, if the auxiliary stirring plate 8 encounters material agglomeration, the resistance it encounters will increase significantly. This is mainly because the materials used to produce mushroom sticks are usually a mixture of various organic substances such as sawdust, bran, cottonseed hulls, etc. During the stirring process, due to uneven water distribution, the physical and chemical properties of the raw materials themselves, and the difference in mechanical stirring force, these materials may stick to each other and form agglomerates.

[0095] The physical form and mechanical properties of the agglomerated material have changed significantly. On the one hand, the volume of the agglomerated material increases, and the contact area with the auxiliary stirring plate 8 is greatly increased compared to the dispersed granular material. When the friction coefficient remains unchanged, the increase in contact area means an increase in positive pressure, which leads to an increase in friction, that is, an increase in the resistance of the auxiliary stirring plate 8. On the other hand, the internal structure of the agglomerated material is compact, with stronger integrity and deformation resistance. When the auxiliary stirring plate 8 tries to push the agglomerated material, it not only has to overcome the friction between the material and the stirring plate, but also has to break the intermolecular force and adhesion structure inside the agglomerated material, which requires more energy and further increases the resistance borne by the auxiliary stirring plate 8.

[0096] When the auxiliary stirring plate 8 rotates with the main stirring plate 7 in the mixing bin, if the material agglomerates, the resistance it encounters will increase suddenly due to the agglomeration. Under normal circumstances, that is, when the material is not agglomerated, the resistance encountered by the auxiliary stirring plate 8 in contact with the material is relatively stable and in a state of equilibrium. Once the material agglomerates, this balance will be broken.

[0097] Due to the increased resistance, the auxiliary stirring plate 8 will slide on the main stirring plate 7 again. In this process, the top of the auxiliary stirring plate 8 will push the auxiliary push rod 14 to move inside the auxiliary stirring plate 8 from Figure 4 As the auxiliary push rod 14 moves, the exposed length of the first blocking block 13 is significantly reduced. According to the lever principle, at this time, the lever arm length of the push plate 10 relative to the blocking ring 12 increases, which causes the blocking force of the first blocking block 13 on the push plate 10 to be greatly reduced. The push plate 10 will pop outward instantly, and use this impact force to violently impact the agglomerated materials on the auxiliary stirring plate 8. In this way, the agglomerated materials are crushed by the impact of the push plate 10, thereby effectively solving the problem of material agglomeration, ensuring the smooth progress of the stirring work, and maintaining the stable operation of the stirring equipment and the continuity of the mushroom stick production.

[0098] When the auxiliary stirring plate 8 slides again in the main stirring plate 7 due to the increased resistance caused by the material agglomeration, the auxiliary slide plate 17 fixedly connected thereto will move synchronously. During the sliding process of the auxiliary slide plate 17, it will interact with the second blocking block 19. As the auxiliary slide plate 17 continues to slide, it will push the second blocking block 19 by its own displacement, thereby squeezing the fourth spring 20, causing the fourth spring 20 to undergo elastic deformation and store elastic potential energy.

[0099] When the material agglomerates are processed and the resistance to the auxiliary stirring plate 8 returns to normal, that is, the pressure disappears, the fourth spring 20 releases its force by virtue of its stored elastic potential energy, pushing the second blocking block 19 to move in the opposite direction, returning it to its initial position, and completing the reset action.

[0100] However, the push plate 10 at this time will not return to the state of being retracted into the auxiliary stirring plate 8 due to the setting of the first spring 11. Only when the auxiliary stirring plate 8 is completely separated from the material, under the stable and continuous elastic force of the third spring 18, each auxiliary stirring plate 8 on the main stirring plate 7 begins to return to the initial position in an orderly manner. In the process of the auxiliary stirring plate 8 returning to its original position, the push plate 10 that has returned to its initial position due to the crushing of the agglomerated material plays a key role. As the auxiliary stirring plate 8 moves, the push plate 10 uses its own position change to cleverly push the first blocking block 13 on its top to rotate in the clockwise direction.

[0101] When the first blocking block 13 rotates until one end is accurately inserted into the push plate 10 , the blocking ring 12 connected to the first blocking block 13 quickly returns to the initial state under the action of the tension spring 25 .
