Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, it relates to a biochar returning machine. Background Technology
[0002] Currently, biochar application mainly relies on the traditional method of manual broadcasting combined with rotary tillage. This method not only significantly disturbs the soil structure and damages soil stability, but also makes it difficult to achieve uniform mixing of biochar and soil particles. Because biochar is lightweight and easily dispersed, uneven distribution during manual broadcasting, followed by shallow rotary tillage, easily leads to aggregation or discontinuity in the topsoil, failing to form a continuous amendment layer. This limits its effectiveness in improving soil physicochemical properties, thus hindering the full realization of biochar's potential in carbon sequestration and emission reduction, soil remediation, and fertility enhancement.
[0003] Furthermore, existing biochar returning machinery commonly suffers from poor discharge during actual operation. Biochar particles are relatively light and have a certain degree of adsorption, making them prone to sticking and accumulating on the walls of the discharge pipe. Especially when the humidity is slightly high, the particles are prone to sticking together and causing pipe blockage, resulting in interrupted or uneven discharge. This seriously affects the continuity of the returning operation and the accuracy of the application rate, reducing operational efficiency and the quality of returning the biochar.
[0004] Therefore, there is an urgent need to develop a biochar returning machine. Utility Model Content

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a biochar returning machine, which has the following beneficial effects: 1. This utility model utilizes an eccentric disc and guide mechanism driven by a motor to drive a sliding plate and connecting ring, causing the feed pipe to generate high-frequency reciprocating motion. This continuous mechanical vibration effectively breaks down the bridging and adhesion of biochar particles within the feed pipe, reducing the risk of material blockage, ensuring smooth and continuous conveying of biochar, and improving the operating efficiency and reliability of the biochar return machine.
[0015] 2. This utility model integrates ditching, material feeding, compaction, and self-cleaning functions into one unit, enabling the completion of multiple processes such as ditching, charcoal application, and soil covering and compaction in one go. This integrated design reduces the number of times the tractor needs to enter the field, lowers energy consumption and soil damage, and improves operational efficiency and overall field return effect, which is in line with the development trend of high efficiency and energy saving in modern agricultural machinery.
[0016] 3. This invention features a fixed scraper in close contact with the pressure roller, which can scrape away soil adhering to the roller surface in real time, preventing soil accumulation from affecting the compaction effect and shape of the roller. Furthermore, a motor drives a threaded rod to move the scraper along the scraper surface, automatically removing soil accumulated on the scraper. This dual cleaning mechanism ensures that the scraper works effectively under any soil moisture conditions, thereby guaranteeing that the pressure roller is always in optimal compaction condition and improving the landfill quality of biochar.

[0022] A biochar returning machine includes a frame 1, a traction frame 2 fixedly connected to the frame 1, a hopper 3 fixedly connected to the upper part of the frame 1, a cover plate 4 hinged to the upper part of the hopper 3, two locking parts 5 fixedly connected to the hopper 3, the locking parts 5 and the cover plate 4 being in a limiting cooperation, two deep loosening shovels 6 fixedly connected to the frame 1, a material pipe 7 fixedly connected and connected to the hopper 3, the lower end of the material pipe 7 being fixedly connected to the deep loosening shovels 6, two connecting frames 8 fixedly connected to the frame 1, pressure rollers 9 being rotatably connected to the connecting frames 8, an anti-blocking structure being provided on the frame 1, and a cleaning structure being provided on the connecting frames 8.
[0023] Please see Figures 2-4 The anti-blocking structure includes a support plate 10, which is fixed to the frame 1. The support plate 10 is fixed to two fasteners 11, and the fasteners 11 are slidably connected to a sliding plate 12. The sliding plate 12 is fixed to a connecting ring 13. The connecting ring 13 is sleeved on the adjacent material pipe 7. The support plate 10 is fixed to a support base 14, and the support base 14 is fixed to a motor 15. The motor 15 is fixed to a disc 16. A fixing post 17 is fixed to the eccentric position of the disc 16. A guide 18 is fixed between the two sliding plates 12. A through groove is provided in the middle of the guide 18. The fixing post 17 slides in the through groove of the guide 18.
[0024] Please see Figure 5 and Figure 6 The cleaning structure includes a support beam 19, a scraper 20 fixedly connected to the support beam 19, the scraper 20 abutting against the pressure roller 9, and two support members 21 fixedly connected to the support beam 19; a guide rod 22 fixedly connected between the two support members 21 and a threaded rod 23 rotatably connected thereto, a scraper 24 slidably connected to the guide rod 22, the scraper 24 being threadedly connected to the threaded rod 23, and a second motor 25 fixedly connected to the support beam 19, the second motor 25 being fixedly connected to the threaded rod 23.
[0025] The working principle of this utility model: The traction frame 2 is connected to the tractor. The tractor drives the frame 1 and its parts to move through the traction frame 2. The frame 1 drives two deep loosening shovels 6 to open trenches in the soil. The biochar particles in the hopper 3 are discharged along the material pipe 7. The biochar particles are discharged into the trenches opened by the deep loosening plant and are squeezed through the connecting frame 8 to drive the pressure roller 9 to move, so that the pressure roller 9 compacts the soil on the upper side of the trench, burying the biochar particles in the soil.
[0026] During the above operation, the motor 15 is started. The output shaft of the motor 15 drives the turntable and the fixed column 17 on it to rotate circumferentially. The fixed column 17 slides along the guide 18, which causes the guide 18 to drive the two sliding plates 12 to slide back and forth along the fixed member 11. The sliding plates 12 drive the material pipe 7 to move back and forth through the connecting ring 13, thereby reducing the accumulation and blockage of biochar particles in the material pipe 7.
[0027] Furthermore, the scraper 20 is always in contact with the pressure roller 9. The scraper 20 cleans the soil clods adhering to the pressure roller 9, thereby improving the landfill effect of the biochar particles. If the soil moisture increases during use, causing a large amount of soil to accumulate on the scraper 20, the motor 25 is started. The output shaft of the motor 25 drives the threaded rod 23 to move back and forth. The threaded rod 23 drives the scraper 24 to move along the upper side of the scraper 20 through the thread, cleaning the soil on the scraper 20, thereby ensuring the cleaning effect of the scraper 20 on the pressure roller 9.
[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here.
