Description

Technical Field

[0001] This utility model relates to the field of soil treatment technology, specifically a straw-based biochar-microorganism synergistic soil improvement device. Background Technology

[0002] Straw-based biochar is a porous carbon material formed by high-temperature pyrolysis of agricultural waste such as straw in an oxygen-deficient or low-oxygen environment. This material has a large specific surface area and rich pore structure, which can effectively improve the physical, chemical and biological properties of soil. At the same time, microorganisms also play an important role in the soil improvement process, which can promote the decomposition of organic matter, nutrient transformation and the formation of soil aggregates.

[0003] However, existing soil improvement technologies often fail to fully leverage the synergistic effect between biochar and microorganisms, resulting in less than ideal improvement effects. Therefore, achieving the mixing of biochar and microorganisms and improving microbial activity is crucial for soil improvement. In response to this situation, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to provide a straw-based biochar-microorganism synergistic soil improvement device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a straw-based biochar-microorganism synergistic soil improvement device, comprising:

[0006] The heating cylinder has a drive device installed at the nozzle, which causes the assembly plate fixed at the end of the drive device to rotate, and causes several perforated curved plates that move on the surface of the assembly plate to rotate axially inside the heating cylinder.

[0007] The heating cylinder has replaceable heating radiation tubes inserted inside. Processing blades are fixed on the axial surface of the heating radiation tubes. When the drive device is running, the inner side of the nesting curved plate rotates to the corresponding position and contacts the outer side of the processing blade, causing the nesting curved plate to move radially toward the inner wall of the heating cylinder with the help of the assembly plate.

[0008] Furthermore, several of the aforementioned nesting curved plates are combined to form a tubular structure, and miniature electro-hydraulic rods matching the number and position of the nesting curved plates are installed on the surface of the assembly plate. The shafts of the miniature electro-hydraulic rods are fixed to the inner sides of the nesting curved plates at corresponding positions.

[0009] Furthermore, the heating cylinder is fixed with a fitting at a position away from the cylinder opening on its central axis, and the fitting is connected to the heating cylinder.

[0010] Furthermore, the driving device includes: a threaded cap, which is screwed onto a threaded section at the opening of the heating cylinder, and a servo motor is mounted at the axial position of the threaded cap, with the shaft of the servo motor fixed to the assembly plate.

[0011] Furthermore, the heating radiant tube is covered with a heat insulation protective layer, and a wire harness plug is installed at the end of the heating radiant tube away from the heating cylinder for supplying power to the heating radiant tube.

[0012] Furthermore, the outer side of the nesting curved plate is provided with a wear-resistant coating to enhance the durability of the nesting curved plate when in contact with the processing blade arm, while reducing the impact of frictional heat on the overall performance of the device.

[0013] Furthermore, the processing blade arm is fin-shaped, and its surface is provided with multiple protrusions that provide better friction when in contact with the nesting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This straw-based biochar-microorganism synergistic soil improvement device uses a drive unit to rotate the assembly plate, causing the perforated curved plate to rotate axially within the heating cylinder. Simultaneously, the heating radiant tube provides a uniform heat source, achieving efficient heating of the straw-based biochar and microorganisms, and stimulating microbial activity.

[0016] In addition, the radial displacement of the nest-shaped plate is controlled by a micro-electro-hydraulic rod to adapt to the treatment needs of different soil environments, enhancing the flexibility and adaptability of the device. It should also be noted that the heat insulation layer effectively reduces heat loss, and combined with the low-energy design of the heating radiation tube, it significantly reduces the overall operating energy consumption.

[0017] Finally, the wear-resistant coating on the outer side of the nested curved plate works synergistically with the raised points on the surface of the treated blade arm to improve friction efficiency, reduce component wear, and extend service life. The fin-like structure of the treated blade arm promotes uniform mixing and breaking of biochar particles, optimizes the pore structure, and creates favorable conditions for microbial attachment and activity.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This device is primarily used for the efficient mixing and processing of biochar and microbial mixtures to improve soil. Specifically, it comprises the following components: a heating cylinder 1, made of heat-resistant metal, used to contain straw-based biochar and microorganisms. A drive device installed at the inlet allows the assembly disc 6, fixed at its end, to rotate stably, and several perforated curved plates 8 movable on the surface of the assembly disc 6 to rotate precisely axially inside the heating cylinder 1, thereby promoting uniform mixing of the internal materials.

[0025] It should be noted that, in this application, the heating cylinder 1 is internally perforated with a replaceable heating radiant tube 5. The heating radiant tube 5 is designed for easy disassembly and maintenance. The heating radiant tube 4 has a heating range of 30℃-60℃, which can effectively improve the activity of microorganisms. When covered with soil, the heat preservation properties of biochar extend the high activity time of microorganisms and improve the soil improvement effect. The axial surface of the heating radiant tube 5 is fixed with a processing blade arm 7. When the drive device is running, the inner side of the nesting curved plate 8 rotates to the corresponding position and comes into close contact with the outer side of the processing blade arm 7. This causes the nesting curved plate 8 to generate a controllable radial displacement towards the inner wall of the heating cylinder 1 by means of the assembly plate 6. This displacement helps to compress and turn over the internal materials and improve the mixing efficiency.

[0026] It is worth noting that in this application, several nesting curved plates 8 are combined to form a complete tubular structure, ensuring that the internal space is sealed. In addition, miniature electro-hydraulic rods 9 are installed on the surface of the assembly plate 6, which match the number and position of the nesting curved plates 8. The shaft of the miniature electro-hydraulic rod 9 is fixed to the inner side of the nesting curved plate 8 at the corresponding position, and the displacement is precisely adjusted by electronic control.

[0027] As a preferred embodiment, in this embodiment, the heating cylinder 1 is fixed with a fitting 2 at a central axis position away from the cylinder opening. The fitting 2 is connected to the heating cylinder 1 and is used to connect to an external conveying pipeline to facilitate the entry and exit of materials.

[0028] Furthermore, it should be noted that the drive device in this embodiment includes: a threaded cap 3, which is screwed onto the threaded section at the opening of the heating cylinder 1 to ensure sealing and stability; a servo motor 4 is installed at the axial position of the threaded cap 3, and the shaft of the servo motor 4 is fixed to the mounting plate 6 to provide constant torque output. The heating radiant tube 5 is covered with a heat insulation protective layer to prevent heat loss. A wiring harness plug is installed at the end of the heating radiant tube 5 away from the heating cylinder 1 to supply power to the heating radiant tube 5, enabling adjustable temperature control.

[0029] As a preferred embodiment, in this embodiment, the outer side of the nest hole curved plate 8 is provided with a wear-resistant coating made of ceramic composite material, which is used to enhance the durability of the nest hole curved plate 8 when in contact with the processing blade arm 7, while reducing the impact of heat generated by friction on the overall performance of the device and extending its service life.

[0030] It should be noted that in this embodiment, the processing blade arm 7 is fin-shaped to optimize fluid dynamics; the surface of the processing blade arm 7 is provided with multiple protrusions, which can provide better friction when in contact with the nesting curved plate 8, ensuring stable contact and energy transfer.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
