Description

Technical Field

[0001] The invention belongs to the field of bamboo material crushing equipment, and in particular relates to bamboo material crushing equipment and a method thereof which is suitable for the particle size requirements of edible fungus cultivation. Background Art

[0002] In the cultivation of edible fungi, the cultivation substrate is a key material that provides the nutrients required for the growth of edible fungi, retains moisture, and supports the growth of mycelium. Bamboo is an ideal cultivation substrate material due to its rich cellulose and lignin content, as well as its easy access and environmentally friendly characteristics. After being crushed, bamboo can provide edible fungi with an environment and nutrients suitable for their growth.

[0003] However, at present, a key difficulty in using bamboo crushing as a new cultivation matrix for edible fungi is that the unique hollow structure of bamboo makes it difficult for traditional crushing equipment to achieve the desired effect. When using a disc-type shredder, due to the hollow characteristics of bamboo, the green part of the bamboo is often unable to be fully cut, resulting in the separation of the green and yellow parts of the bamboo, resulting in the length of the chopped bamboo being too long, and the long thorny bamboo easily piercing the tube bag, increasing the probability of contamination of the mushroom stick. This situation not only affects the uniformity of the matrix, but also brings losses in production, and ultimately affects the demonstration and promotion of the cultivation technology of edible fungi replacing wood with bamboo. In addition, the existing drum shredder also faces similar problems in the transportation and processing of bamboo, that is, the shredding effect of the green bamboo is not ideal, and the shredded green bamboo particles are too large. These larger green bamboo fragments are easy to pierce the packaging bag during the subsequent bagging process, resulting in air leakage in the bag. This air leakage phenomenon not only affects the moisture retention and oxygen control of the matrix, but also increases the risk of invasion of miscellaneous bacteria, thereby causing contamination of the matrix, and ultimately affecting the quality and yield of edible fungi.

[0004] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] See also Figure 1-8 As shown, in this embodiment, a bamboo material crushing equipment suitable for the particle size requirements of edible fungus cultivation is provided, including a shell 1, a first side of the shell 1 is provided with a feed port 2, a second side of the shell 1 is provided with a discharge port, four corners at the bottom of the shell 1 are fixedly connected with support legs 3, a movable port 4 is provided at the top of the shell 1, and a connecting frame 5 located in the cavity of the shell 1 is movably connected inside the movable port 4; a fine-toothed roller 32 near the feed port 2 and a crushing roller 6 near the discharge port are rotatably connected in the space of the shell 1, a secondary crushing mechanism 7 is rotatably connected below the crushing roller 6, a compacting roller 8 affixed to the top of the fine-toothed roller 32 is rotatably connected below the connecting frame 5, a conveying space is provided between the fine-toothed roller 32 and the crushing roller 6, a discharge conveying device 9 located below the secondary crushing mechanism 7 is provided below the space of the shell 1, and the discharge conveying device 9 is driven by a motor.

[0040] The present invention can effectively solve the shredding problem caused by the hollow structure of bamboo by setting a multi-stage crushing system. Different from the traditional disc shredder and drum shredder, the equipment in the present invention adopts a combination design of a fine-tooth roller 32 and a compaction roller 8 to ensure that the bamboo green is fully compacted before entering the crushing process, avoiding the separation of bamboo green and bamboo yellow, so that it can be evenly cut to the required small particle size standard during the crushing process, reducing the long thorny bamboo green. This improvement reduces the problems of broken bags caused by the long thorny bamboo green, reduces the loss caused by the contamination of mushroom sticks caused by the bamboo green thorn bags in the cultivation of edible fungi with bamboo instead of wood, and at the same time improves the uniformity of the matrix, providing a more ideal environment for the healthy growth of edible fungi mycelium. Thereby providing support for the demonstration and promotion of the cultivation technology of edible fungi with bamboo instead of wood. The equipment in the present invention further refines the bamboo particles through the innovative secondary crushing mechanism 7, avoiding the problem of too large bamboo particles. Smaller and uniform particles not only help to improve the efficiency of the bagging process, but also avoid the phenomenon of puncturing the packaging bag and causing air leakage due to the excessive size of bamboo green in traditional equipment. This design effectively prevents moisture retention and oxygen control problems of the matrix due to air leakage, reduces the risk of bacterial contamination, and ensures the cleanliness and safety of the matrix.

[0041] When the crushing operation is performed, the bamboo material is first smoothly conveyed to the space between the fine-tooth roller 32 and the compacting roller 8 of the equipment through a conveyor belt or other suitable conveying methods. At this time, by adjusting the position of the connecting frame 5, the compacting roller 8 in the connecting frame 5 is closely attached to the surface of the fine-tooth roller 32 to ensure that the bamboo material is fully compacted and fixed before entering the crushing stage. The compacted bamboo material is smoothly conveyed to the crushing roller 6 under the joint action of the fine-tooth roller 32 and the compacting roller 8. Under the high-speed rotation of the crushing roller 6, the bamboo material is effectively crushed into particles. The crushed bamboo particles are then introduced into the secondary crushing mechanism 7, which further crushes these particles more finely to ensure that the size of the particles meets specific requirements. The bamboo particles after the secondary crushing finally fall onto the discharge conveying device 9 below, and the material is transmitted through the device, so that the entire crushing process can be successfully completed and meet the strict requirements of edible fungus cultivation on the particle size of bamboo particles.

[0042] In this embodiment, the crushing roller 6 includes a rotating roller 10 rotating in the space of the shell 1, two notches 11 are provided on the circumference of the rotating roller 10, and a crushing blade 12 is installed inside the notch 11. The end of the rotating roller 10 extending out of the shell 1 is connected to a transmission wheel A13, and a first servo motor is fixedly connected above the discharge port of the shell 1, and the output end of the first servo motor is connected to a transmission wheel B14, and the transmission wheel A13 and the transmission wheel B14 are driven by a belt. When the transmission wheel A13 and the transmission wheel B14 are connected by a belt transmission system, the belt can not only transmit power and make the two transmission wheels rotate synchronously, but also have a certain buffering effect. During the operation of the equipment, the transmission wheel A13 and the transmission wheel B14 may generate impact force due to instantaneous load changes or speed differences. The flexible characteristics of the belt drive can effectively absorb and alleviate these impacts, and reduce the vibration and wear inside the transmission system. At the same time, this buffering effect helps to extend the service life of the transmission system, maintain the smooth operation of the equipment, and prevent mechanical failures caused by sudden load changes. Overall, the belt drive system not only ensures the power transmission between the transmission wheels, but also provides additional protection functions, allowing the equipment to maintain a stable working state under long-term, high-intensity operating conditions.

[0043] In this embodiment, one side of the crushing blade 12 is fixedly connected with two guide posts, one side of the notch 11 is provided with a guide groove adapted to the guide post, one side of the notch 11 is provided with a plurality of threaded holes arranged in a straight line, and one side of the crushing blade 12 is provided with a knife pressing plate 15, and the opposite side of the knife pressing plate 15 and the blade is penetrated with mounting holes 16 corresponding to the threaded holes, and the mounting holes 16 are plugged with bolts located in the threaded holes. Through the precise matching between the guide posts and the guide grooves, the crushing blade 12 can be accurately positioned during installation. Specifically, the guide posts are inserted into the corresponding guide grooves, so that the crushing blade 12 can slide into the specified position along a predetermined trajectory during installation. This design ensures that the blade is accurately positioned during installation and avoids installation errors caused by offset or misalignment. After the blade is positioned, the blade is firmly fixed inside the notch 11 with the assistance of the knife pressing plate 15. The blade pressing plate 15 is pressed against one side of the blade to ensure that there is no looseness or gap between the blade and the notch 11. Bolts are then passed through the blade pressing plate 15 and the mounting holes 16 on the blade to fasten them together. The firm connection of the bolts further ensures that the blade will not loosen or fall off during high-load operation. This multiple fixing method not only improves the reliability of blade installation, but also enhances the safety and stability of the equipment during operation, avoiding equipment damage or operational risks caused by blade falling off.

[0044] In this embodiment, a second servo motor 17 is provided on one side of the housing 1, and the second servo motor 17 rotates through the fine-tooth roller 32 of the reducer. Through the clever cooperation between the second motor and the reducer, the rotation effect of the fine-tooth roller 32 can be significantly improved. Specifically, the second motor provides a sufficient power source for the fine-tooth roller 32, and the reducer adjusts the high-speed rotation output of the motor and converts it into a low-speed high-torque output that is more suitable for the fine-tooth roller 32. This power conversion not only ensures the stability of the rotation speed of the fine-tooth roller 32, but also enhances its cutting force and bite force when processing bamboo. The addition of the reducer allows the power of the motor to be more smoothly and efficiently transmitted to the fine-tooth roller 32, effectively reducing the problem of unstable speed or insufficient power that may be caused by direct drive. At the same time, this cooperation can also reduce the wear of the motor and mechanical system, and improve the overall operating efficiency and service life of the equipment. Through this optimized drive scheme, the fine-tooth roller 32 can better cope with bamboo of different hardness and size, ensuring that the bamboo is fully pre-treated before entering the crushing stage, and improving the effect and production capacity of the entire crushing process.

[0045] In this embodiment, the compaction roller 8 includes a roller body 33 that rotates above the feed port 2, and the outer walls of the roller body 33 are fixedly connected with connecting teeth 18 on both sides, and a plurality of fixed teeth 19 are fixedly connected in a ring arrangement between the two connecting teeth 18. Through the precise cooperation between the connecting teeth 18 and the fixed teeth 19, the main material can be effectively compacted. Specifically, the interaction between the connecting teeth 18 and the fixed teeth 19 makes the main material receive a uniform and stable compaction pressure when passing through the equipment, ensuring that its shape and density are controlled and optimized. The fixed teeth 19 adopt a triangular structure, which has multiple advantages. First, the fixed teeth 19 of the triangular structure can form multiple points of contact with the surface of the main material during the compaction process, which not only increases the contact area, but also improves the uniformity of compaction. Secondly, the tip of the triangle can be embedded more deeply into the surface of the main material, making the compaction process more thorough, effectively reducing the gaps inside the main material, and ensuring the consistency of its density. In addition, this structure can better disperse the force when applying pressure, reduce excessive pressure on a single point, and thus reduce the risk of damage or deformation on the surface of the main material. Through this optimized design, the cooperation between the connecting teeth 18 and the fixed teeth 19 not only improves the efficiency and effect of the compaction process, but also ensures that the main material has an ideal physical state when entering the subsequent processing steps, thus laying the foundation for improving the overall processing quality.

[0046] The roller body 33 passes through one end of the connection frame 5 and is fixedly connected to a transmission wheel C20. A mounting plate is connected above the inner wall of the connection frame 5. A third servo motor 21 is connected above the mounting plate. The output end of the third servo motor 21 is connected to a transmission wheel D22. The transmission wheel C20 and the transmission wheel D22 are driven by a belt, and a sliding groove 23 is provided on the opposite side of the housing 1 for the roller body 33 to extend out of the connection frame 5 and slide. By cleverly arranging the third servo motor 21 in the internal space of the connection frame 5, motion interference can be effectively avoided during the adjustment of the connection frame 5. Specifically, when the connection frame 5 needs to be adjusted in position according to different operating requirements, the position arrangement of the servo motor ensures that there will be no physical interference between it and other components during the entire adjustment process. This design not only simplifies the structural layout of the equipment, but also enhances the overall coordination and stability of the system.

[0047] In addition, the setting of the sliding groove 23 further optimizes the operability of the equipment. The sliding groove 23 provides a special guide path for the roller body 33, so that the roller body 33 can move smoothly and steadily during the adjustment process of the connecting frame 5. This design avoids the situation where the connecting frame 5 cannot move normally due to friction or jamming between the roller body 33 and the sliding groove 23. The existence of the sliding groove 23 ensures that the movement of the roller body 33 is always within a controllable range, which not only improves the adjustment accuracy of the equipment, but also prevents equipment failures caused by mechanical resistance or misoperation. The combination of these optimization measures makes the entire system more flexible and reliable in operation, and provides a solid guarantee for achieving efficient bamboo processing.

[0048] In this embodiment, a first U-shaped frame 24 is fixedly connected to one side of the shell 1, a second U-shaped frame 25 corresponding to the first connecting frame 5 is fixedly connected to one side of the connecting frame 5, and a telescopic cylinder 26 is provided between the first U-shaped frame 24 and the second U-shaped frame 25. By providing the telescopic cylinder 26, the position of the connecting frame 5 can be flexibly adjusted, thereby achieving precise control of the position of the compacting roller 8. Specifically, the telescopic cylinder 26 can accurately expand or contract according to operational requirements, pushing the connecting frame 5 to move up and down within a specified range. This adjustment function enables the compacting roller 8 to adjust its position at any time according to the size of different bamboo materials, thereby changing the distance between the compacting roller 8 and the fine-toothed roller 32. The flexibility of this design enables the equipment to easily adapt to bamboo materials of various specifications. Whether it is thick bamboo with a larger diameter or thinner bamboo pieces, the best compaction effect can be achieved by adjusting the position of the compacting roller 8.

[0049] In this embodiment, the secondary crushing mechanism 7 includes a guide frame 27 fixedly connected between the side walls of the cavity, two crushing rods 28 are rotatably connected inside the guide frame 27, and the feed port 2 of the guide frame 27 is located below the place where the bamboo particles fall, and the guide frame 27 is slidably connected below the guide frame 27 with a scattering mechanism. The process of secondary crushing by the two crushing rods 28 can significantly improve the crushing effect of the bamboo particles, making them closer to the ideal particle size standard. Specifically, after the initial crushing, the bamboo particles have been preliminarily crushed, but there may be uneven particle sizes or some particles are still large. At this time, the secondary crushing step of the two crushing rods 28 plays a key role. The two crushing rods 28 rotate separately, and further squeeze and cut the bamboo particles after the initial crushing at different angles and pressures, so as to crush these larger particles into smaller and more uniform particles again. This fine processing of secondary crushing not only effectively reduces the particle size of the bamboo particles, but also greatly improves the consistency and uniformity of the particles.

[0050] In this embodiment, the scattering mechanism includes a rotating rod 29 rotatably connected to the bottom of the two crushing rods 28, and a plurality of scattering plates 30 are connected to the circumference of the rotating rod 29 in a circular arrangement. The rotating rod 29 and the first end of the crushing rod 28 extending out of the housing 1 are both connected to a synchronous wheel 31, and the plurality of synchronous wheels 31 are driven by a synchronous belt, and the second end of the rotating rod 29 extending out of the housing 1 is connected by a servo motor. By providing the scattering plate 30, the bamboo particles that may be gathered together after the secondary crushing by the crushing rod 28 can be further dispersed effectively. Specifically, after the crushing rod 28 performs secondary crushing on the bamboo particles, some particles may aggregate into small pieces or clumps due to the small size of the particles and the slight adhesion on the surface. This aggregation phenomenon not only affects the uniformity of the particles, but may also lead to uneven distribution in subsequent use, thereby affecting the performance of the bamboo particles in the edible fungus cultivation matrix.

[0052] S1: The bamboo to be processed is transported to between the fine-tooth roller and the compaction roller 8 of the bamboo crushing equipment through a conveyor belt, and then the position of the connecting frame 5 is adjusted so that the compaction roller 8 is closely attached to the surface of the fine-tooth roller;

[0053] S2: The fine-tooth roller and the compaction roller 8 work together to transport the bamboo to the crushing roller 6 for preliminary crushing;

[0054] S3: The bamboo particles after the initial crushing fall into the secondary crushing mechanism 7, and the two crushing rods 28 further refine the particles;

[0055] S4: After the secondary crushing, the bamboo particles are processed by the scattering mechanism, and the scattering plate 30 arranged under the crushing rod 28 fully disperses the aggregated bamboo particles, further improving the dispersion and uniformity of the particles;

[0056] S5: After secondary crushing and breaking up, the bamboo particles fall onto the discharging conveyor, and the crushed particles are transported out of the crushing equipment through the discharging conveyor.
