Obviously, the described embodiments are some but not all of the embodiments of the present utility model.

[0049] Below in conjunction with Figures 1 to 7 Describe the scallion earthing-up device of the present utility model.

[0050] The green onion soiling device is a device for mechanized soiling in order to increase the proportion of green onion white during the growth cycle of green onions. Green onions need to be soiled 2 to 3 times for small soiling and 3 to 4 times for large soiling during the growth cycle. The specific number of soiling is also combined with the ridge spacing when the green onions are planted. Therefore, the green onion soiling device should have the function of adjusting the soiling requirements according to different ridge spacing. The soil for green onion planting is generally granular dark brown clay loam. Such soil is generally loose, deep, fertile, well-drained and rich in organic matter. Therefore, the soil needs to be broken up appropriately before soiling.

[0051] In some embodiments, Figures 1 to 3 As shown, the green onion soil-cultivating device comprises: a driving mechanism 1, a rotary tillage mechanism 2 and a soil-cultivating mechanism 3. The rotary tillage mechanism 2 comprises: a transmission assembly 21, a depth adjustment assembly 22 and a rotary tillage assembly 23; the driving mechanism 1 is connected to the rotary tillage assembly 23 through the transmission assembly 21, the depth adjustment assembly 22 is arranged on the rotary tillage assembly 23, and the depth adjustment assembly 22 is used to adjust the rotary tillage depth of the rotary tillage assembly 23; the soil-cultivating mechanism 3 comprises: a rotating shaft assembly 31 and a pipe body 32; the pipe body 32 is provided with a feed inlet and a discharge outlet, the driving mechanism 1 is connected to the rotating shaft assembly 31 through the transmission, and the rotating shaft assembly 31 is arranged in the pipe body 32, so as to drive the rotating shaft assembly 31 through the driving mechanism 1, and the rotating shaft assembly 31 transports the soil at the feed inlet to the discharge outlet.

[0052] In this embodiment, the driving mechanism 1 is the power source of the entire device. The driving mechanism 1 provides the necessary power for the rotary tillage mechanism 2 and the soil-building mechanism 3 through transmission methods such as gears, chains, and belts. The rotary tillage mechanism 2 is responsible for loosening the soil in preparation for soil-building. Among them, the transmission component 21 is a bridge connecting the driving mechanism 1 and the rotary tillage component 23. Through the transmission component 21, the power of the driving mechanism 1 can be transmitted to the rotary tillage component 23 to drive it to rotate. The setting of the depth adjustment component 22 allows the user to adjust the depth of rotary tillage according to actual needs. This is very important for the needs of different soil conditions and green onion growth stages, and can ensure that the soil is properly loosened without damaging the root system of green onions. The rotary tillage component 23 is a part that directly contacts the soil, and loosens the soil by high-speed rotation. The soil-building mechanism 3 is responsible for transporting the loosened soil to the roots of green onions for soil-building, and is mainly composed of a shaft component 31 and a tube body 32: the shaft component 31 is arranged in the tube body 32 and rotates by the drive of the driving mechanism 1. Its main function is to transport the soil from the feed port to the discharge port to complete the soil transportation process. The pipe body 32 is provided with a feed port and a discharge port, the feed port is used to receive the loosened soil, and the discharge port is aimed at the root of the green onion to transport the soil for soil cultivation.

[0053] During operation, the drive mechanism 1 is activated, and through the transmission assembly 21, it provides power for the rotary tillage assembly 23. The rotary tillage assembly 23 starts to rotate and loosen the soil. The depth adjustment assembly 22 is adjusted as needed to ensure an appropriate tillage depth. The loosened soil enters the feeding port of the soil banking mechanism 3 in a certain way (such as natural flow or auxiliary conveying device). The drive mechanism 1 simultaneously drives the rotating shaft assembly 31 to rotate, and the rotating shaft assembly 31 conveys the soil at the feeding port to the discharging port. The soil flows out from the discharging port and covers the roots of the green onions, completing the soil banking process.

[0054] The green onion soil banking device provided by the present utility model combines the drive mechanism 1, the rotary tillage mechanism 2, and the soil banking mechanism 3, achieving the continuity and high efficiency of the green onion soil banking operation. The drive mechanism 1 directly drives the rotary tillage assembly 23 to till the soil, and flexibly adjusts the tillage depth through the depth adjustment assembly 22 to meet the soil banking requirements of green onions at different growth stages. At the same time, the soil banking mechanism 3 uses the rotating shaft assembly 31 to quickly convey the tilled soil to the ridges, greatly shortening the operation cycle and improving the overall operation efficiency. This device reduces the labor burden of users through mechanized operation, making the soil banking operation easier and more convenient.

[0055] In some embodiments, such as Figures 1 to 3 shown, since the soil banking depths in different soil banking stages of green onions are different, a device needs to be designed to adjust the tillage depth each time according to the requirements of different soil banking periods, so as to control the soil banking amount. The depth adjustment assembly 22 is used to control the tillage depth to adapt to the needs of different crops and soil conditions.

[0056] The depth adjustment assembly 22 includes: a depth adjustment rod 221 and a depth adjustment wheel 222. One end of the depth adjustment rod 221 is movably connected to the rotary tillage assembly 23; the depth adjustment wheel 222 is used to support on the ground, and the depth adjustment wheel 222 is rotatably connected to the other end of the depth adjustment rod 221; during the process of the depth adjustment rod 221 moving relative to the rotary tillage assembly 23, the rotary tillage assembly 23 adjusts the distance relative to the ground.

[0057] In this embodiment, the depth adjustment rod 221 is a component connecting the rotary tillage assembly 23 and the depth adjustment wheel 222. One end of it is movably connected to the rotary tillage assembly 23, and the depth adjustment rod 221 can move up and down or rotate relative to the rotary tillage assembly 23 within a certain range, thereby changing the relative distance between the rotary tillage assembly 23 and the ground. This movable connection is usually achieved through a pin shaft, a sliding groove, or other mechanical structures to ensure that the depth adjustment rod 221 can move stably and flexibly. The depth adjustment wheel 222 is a component that supports on the ground and rotates as the ground undulates. The depth adjustment wheel 222 is rotatably connected to the other end of the depth adjustment rod 221, so that the depth adjustment wheel 222 can roll smoothly when contacting the ground, reducing friction and resistance.

[0058] When the tillage depth needs to be adjusted, the operator can change the relative distance between the tillage assembly 23 and the ground by adjusting the position of the depth adjustment rod 221 relative to the tillage assembly 23. Specifically, when the lower end of the depth adjustment rod 221 moves upward, the distance between the tillage assembly 23 and the opposite side is shortened, thereby increasing the tillage depth; conversely, when the lower end of the depth adjustment rod 221 moves downward, the tillage assembly 23 rises and reduces the tillage depth. During the adjustment process, the depth adjustment wheel 222 always keeps in contact with the ground and rotates with the ups and downs of the ground.

[0059] In one example, if Figures 1 to 5 As shown, the rotary tillage assembly 23 includes: a guard 231, a knife roller shaft 232, a worm gear 233 and a rotary tillage blade 234. The guard 231 is connected to one end of the depth adjustment rod 221. The knife roller shaft 232 and the worm gear 233 are both arranged in the guard 231, and the knife roller shaft 232 is connected to the transmission assembly 21 through the worm gear 233; the rotary tillage blade 234 is arranged on the knife roller shaft 232.

[0060] The shield 231 is the outer shell of the rotary tillage assembly 23. The shield 231 not only protects the internal mechanical structure from direct impact of soil and impurities, but also ensures the safety of rotary tillage operation to prevent splashing stones or fragments from injuring people. The shield 231 has a solid support structure to ensure that the rotary tillage device can work stably under complex working conditions. It is closely connected to one end of the depth adjustment rod 221, and indirectly controls the lifting and lowering of the entire rotary tillage assembly 23 by the up and down movement of the depth adjustment rod 221, so as to accurately adjust the rotary tillage depth. The knife roller shaft 232 is the main bearing component of the rotary tillage blade 234. The knife roller shaft 232 is designed to be sturdy and durable, and can withstand the huge torque and impact force generated during the rotary tillage process. The knife roller shaft 232 is connected to the transmission assembly 21 through a worm gear 233. The knife roller shaft 232 is usually made of high-strength material to withstand the huge stress in soil operation. The knife roller shaft 232 is generally selected to be horizontally placed (horizontal axis type) or vertically set (vertical axis type). The horizontal axis type is more common because it can better adapt to different types of soil and operation requirements. This design adopts a horizontal axis type, and the material is 65 manganese steel, because this is a specially treated spring steel with good toughness and wear resistance, suitable for making parts that need to withstand impact and wear. The worm gear 233 serves as a bridge between the transmission assembly 21 and the knife roller shaft 232. The rotary tillage blade 234 is arranged on the knife roller shaft 232 to ensure that the soil can be effectively loosened and the soil blocks can be cut during the rotation process.

[0061] like Figure 5As shown, the rotary tillage blades 234 are distributed in a specific spiral arrangement and can be straight or curved. This arrangement enables the rotary tiller, when moving forward, to not only rotate the rotary tillage blades 234 but also push the soil forward, achieving the effects of cutting, turning, and mixing the soil. The design of the rotary tillage blades 234 needs to consider wear resistance and sharpness to ensure good soil cutting performance and a long service life. In this design, curved blades are used, and the blade material is high carbon steel, as it is one of the most common materials, having good wear resistance but being relatively prone to breakage. The high carbon steel rotary tillage blades 234 can be applicable to most conventional tillage conditions.

[0062] In addition, in addition to soil crushing and turning, the rotary tillage assembly 23 also needs to have a certain soil crushing and leveling ability. This is achieved through the design of the blades (increasing the number of cutting edges, shape adjustment) and additional pressing rollers or drag plates to ensure that the soil surface is level after tillage, creating a good soil environment for the growth of scallions.

[0063] In one example, the tillage width of the rotary tillage assembly 23 is 0.3 m, the tillage depth is 0.12 m, the working speed is 0.2 m / s, the rotary cutting diameter of the rotary tillage blades 234 is 330 mm, and the rotational speed is 200 n / r. A total of four cutter discs are installed at both ends of the cutter roller shaft 232, and each cutter disc is equipped with 4 rotary tillage blades 234. The material of the cutter roller shaft 232 is 45 steel and is quenched and tempered.

[0064] For convenient power transmission, as Figures 1 to 3 shown, the transmission assembly 21 includes: a first pulley 211, a first transmission belt 212, and a transmission shaft 213; the first pulley 211 is connected to the output end of the driving mechanism 1, and the driving mechanism 1 is in transmission connection with the worm gear 233 through the first pulley 211, the first transmission belt 212, and the transmission shaft 213.

[0065] Specifically, the first pulley 211 is directly connected to the output end of the driving mechanism 1. It is usually made of high-strength and wear-resistant materials to ensure stable power transmission during high-speed rotation. The first transmission belt 212 is the component connecting the first pulley 211 and the transmission shaft 213. It is usually made of rubber, polyurethane, or other elastic materials, having good flexibility and wear resistance. The first transmission belt 212 withstands the tension and torque during the transmission process through the internal fiber or steel wire and other reinforcing layers to ensure that the power can be smoothly and reliably transmitted to the transmission shaft 213. The transmission shaft 213 cooperates with the worm gear 233 to achieve power reduction and transmission. The design of the transmission shaft 213 considers the meshing accuracy and transmission ratio with the worm gear 233 to ensure a stable transmission relationship and high transmission efficiency during the rotary tillage process.

[0066] In summary, through the close cooperation of the first pulley 211, the first transmission belt 212, and the transmission shaft 213, the transmission assembly 21 realizes efficient and stable power transmission from the drive mechanism 1 to the rotary tillage assembly 23. This design not only improves the operation efficiency of the scallion ridging device but also enhances its reliability and durability.

[0067] The material selection of the transmission shaft 213 is crucial, directly affecting the transmission efficiency, durability, maintenance cost, and overall performance of the equipment. When selecting the material for the transmission shaft 213 of a micro-tiller, factors such as strength and stiffness, wear resistance, corrosion resistance, machining performance, and environmental adaptability need to be considered. The selected material must have sufficient strength and stiffness to withstand the torque and dynamic loads generated during transmission, ensuring that it is not prone to bending or breaking during long-term use. Commonly used high-strength materials include high-quality carbon steel (such as 45 steel) and alloy steel, and their mechanical properties can be further improved through heat treatment (such as quenching and tempering). The agricultural operation environment is complex and changeable, and foreign objects such as soil and sand may cause wear to the transmission shaft 213. Therefore, selecting wear-resistant materials or surface treatment technologies (such as chrome plating, carburizing) can increase its anti-wear ability and extend its service life. Given that micro-tillers often work outdoors and in humid environments, the material should have a certain degree of corrosion resistance to resist the corrosion of acidic and alkaline substances in rainwater and soil. Stainless steel or carbon steel treated with anti-corrosion is a better choice. The material should be easy to process into various shapes, including cutting, welding, heat treatment, etc., to reduce the manufacturing cost and ensure the quality stability of mass production. For micro-tillers operating in extreme temperature difference environments, the material of the transmission shaft 213 should be able to maintain good mechanical properties to avoid brittle fracture at low temperatures or softening at high temperatures.

[0068] It should be noted that the material selection of the drive shaft 213 is crucial, directly affecting the transmission efficiency, durability, maintenance cost and the overall performance of the equipment. When selecting the material for the drive shaft 213 of the micro-tiller, factors such as strength and stiffness, wear resistance, corrosion resistance, machinability and environmental adaptability need to be considered. The selected material must have sufficient strength and stiffness to withstand the torque and dynamic loads generated during transmission, ensuring that it is not prone to bending or breaking during long-term use. Commonly used high-strength materials include high-quality carbon steel (such as 45 steel) and alloy steel, and their mechanical properties can be further improved through heat treatment (such as quenching and tempering). The agricultural operation environment is complex and changeable, and foreign objects such as soil and sand may cause wear to the drive shaft 213. Therefore, selecting wear-resistant materials or surface treatment technologies (such as chromium plating, carburizing) can increase its anti-wear ability and extend its service life. Given that the micro-tiller often works outdoors and in humid environments, the material should have a certain degree of corrosion resistance to resist the corrosion of acidic and alkaline substances in rainwater and soil. Stainless steel or carbon steel with anti-corrosion treatment is a better choice. The material should be easy to process and form, including cutting, welding, heat treatment, etc., to reduce the manufacturing cost and ensure the quality stability of mass production. For the drive shaft 213 of the micro-tiller working in an extreme temperature difference environment, the material should be able to maintain good mechanical properties and avoid brittle fracture at low temperature or softening at high temperature.

[0069] As Figure 7 shown, the circumferential positioning design of the drive shaft 213 is the key to ensuring stable and non-slip rotation between it and the connected components (such as gears, couplings, etc.). The main purpose of circumferential positioning is to prevent the parts on the shaft from moving axially and ensure that they can accurately transmit torque. Some common circumferential positioning methods are: key connection, spline connection, interference fit, forming connection and adapter sleeves and lock nuts.

[0070] When designing the circumferential positioning of the drive shaft 213, factors such as load type, rotational speed, alignment requirements, installation and maintenance convenience, and cost also need to be comprehensively considered. Key connection is one of the most commonly used circumferential positioning methods. By inserting a key (such as a flat key, a half-round key, a wedge key, etc.) between the shaft and the hub (or other parts), the mutual restraint between the key and the keyway is used to prevent relative sliding. Flat keys are widely used in light and medium load applications due to their simple structure, easy assembly and disassembly, and good alignment. Spline connections can provide higher load-carrying capacity and more accurate alignment, and are suitable for heavy load and high-precision transmission applications. Splines are divided into rectangular splines, involute splines, etc., and circumferential fixation is achieved through the matching tooth profiles on the shaft and the hub, and they can also withstand a certain axial force. Therefore, spline connection is selected in this design to ensure the stability and reliability of the transmission system.

[0071] In this embodiment, the first drive belt 212 generally uses a belt. As a widely used mechanical transmission method, belt drive has the following significant advantages:

[0072] (1) Buffering and shock absorption: The elasticity of the belt can absorb and reduce the vibration during the operation of the machine, making the rotary tiller run more smoothly, reducing the impact on the machine body and engine, and extending the service life of the machine.

[0073] (2) Cost-effectiveness: The belt drive structure is relatively simple, with low manufacturing and installation costs. Maintenance and replacement of belts are also more economical and convenient, which helps to reduce the overall equipment cost.

[0074] (3) Overload protection: When encountering excessive resistance or unexpected load, the belt will slip first instead of immediately damaging other transmission components, thus protecting the engine and transmission system and avoiding more serious mechanical damage.

[0075] (4) Strong adaptability: Belt drive allows for a larger center distance, which is suitable for agricultural machinery such as rotary tillers that require a larger working space and flexibility. At the same time, the requirements for installation position and centering are not as strict as those for gear drive, which increases design flexibility.

[0076] (5) Low noise: Compared with gear drive, belt drive produces lower noise during operation, creating a quieter working environment and reducing interference to operators and the surrounding environment.

[0077] (6) Simple maintenance: The belt drive system is easy to inspect and maintain, the belt tension adjustment is relatively simple, and replacing the belt usually does not require specialized tools or skills.

[0078] (7) Non-fixed transmission ratio: Although it may be regarded as a disadvantage in some precision transmission applications, a fixed transmission ratio is not necessary for rotary tillage and soil cultivation operations. This feature of belt drive is just suitable for agricultural machinery applications that do not have strict requirements on the transmission ratio.

[0079] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in the figure, the spacing between large ridges after the green onion is set is 65-70 cm, the spacing between small ridges is 50-55 cm, and the furrow depth is about 25 cm. Therefore, the furrow is wide, and after the rotary tillage mechanism 2 breaks up the soil in the ridge, it is necessary to use a spiral conveyor to transfer the soil to both sides so that the conveying devices on both sides can transport the soil to the ridge.

[0080] Thus, the rotating shaft assembly 31 includes: a spiral shaft 311 and spiral blades 312. The spiral shaft 311 is disposed within the pipe body 32 and is in transmission connection with the driving mechanism 1 through a universal joint. The spiral blades 312 are connected to the spiral shaft 311. The spiral shaft 311 is the main part of the rotating shaft assembly 31 and is disposed within the pipe body 32. At the same time, the spiral shaft 311 is also in transmission connection with the driving mechanism 1 through a universal joint. This connection method allows the spiral shaft 311 to stably receive and transmit power while maintaining a certain angular variation. The design of the universal joint enables the rotating shaft assembly 31 to adapt to different installation angles and working environments, improving the flexibility and adaptability of the device. The spiral blades 312 rotate along with the rotation of the spiral shaft 311 and convey the soil from the feed port to the discharge port. The universal joint allows the spiral shaft 311 to stably receive and transmit power while maintaining a certain angular variation, thus ensuring the normal operation of the rotating shaft assembly 31 under various working conditions.

[0081] The design of the spiral shaft 311 and the spiral blades 312 is relatively simple, occupies a small area, has good airtightness, can be flexibly arranged (installed horizontally, inclined or vertically), and can adapt to diverse material characteristics. However, it is not suitable for conveying large pieces, highly viscous or easily caking materials, because these materials are prone to clogging the pipeline. During operation and use, it is necessary to follow the correct operation procedures, such as ensuring no-load startup, uniform and continuous feeding, regular inspection and maintenance, etc., to ensure the efficient and stable operation of the equipment.

[0082] In this embodiment, the pipe body 32 includes: a first conveying pipe 321, a second conveying pipe 322, and a third conveying pipe 323. The spiral shaft 311 is disposed within the first conveying pipe 321, and a feed port is provided on the first conveying pipe 321. The second conveying pipe 322 is connected to one end of the first conveying pipe 321 and is disposed at an angle with respect to the first conveying pipe 321; the third conveying pipe 323 is connected to the other end of the first conveying pipe 321 and is disposed at an angle with respect to the first conveying pipe 321. Discharge ports are provided on the second conveying pipe 322 and the third conveying pipe 323.

[0083] In this embodiment, the first conveying pipe 321 serves as the main load-bearing part of the rotating shaft assembly 31. The spiral shaft 311 is disposed inside the first conveying pipe 321, and the spiral blades 312 on the spiral shaft 311 are responsible for conveying the soil from the feed port to both ends. The feed port on the first conveying pipe 321 is the entrance for the soil to enter the pipe body 32, and its position and design need to consider the soil source and the feeding efficiency.

[0084] The second conveying pipe 322 is connected to one end of the first conveying pipe 321 and is arranged at an angle with respect to the first conveying pipe 321. This angular design enables the soil to change direction during transportation, thus meeting different soil covering requirements. For example, in scallion planting, it may be necessary to transport the soil to different positions at the roots of scallions, and the angle adjustment of the second conveying pipe 322 can meet this need. The discharge port on the second conveying pipe 322 is a port for soil output, and its position and size need to be adjusted according to actual requirements. Similar to the second conveying pipe 322, the third conveying pipe 323 is connected to the other end of the first conveying pipe 321 and is also arranged at an angle with respect to the first conveying pipe 321. In this way, the third conveying pipe 323 provides an output port for soil transportation in another direction. During the soil covering process of scallions, the third conveying pipe 323 can be used to transport the soil to the opposite side of the scallion roots or to other areas that require soil covering. The discharge port on the third conveying pipe 323 also needs to be adjusted according to actual requirements.

[0085] For facilitating power transmission, the soil covering mechanism 3 further includes: a second pulley 33 and a second transmission belt 34; the driving mechanism 1 is sequentially connected to the spiral shaft 311 through the transmission assembly 21, the second transmission belt 34, the second pulley 33, and a universal joint. The second pulley 33 is an important node in the power transmission path and is designed to closely cooperate with the second transmission belt 34. The second pulley 33 usually has a high-strength and wear-resistant material to ensure stable power transmission during high-speed rotation. The second transmission belt 34 is a component connecting the second pulley 33 and the universal joint, and it is responsible for further transmitting the power transmitted by the driving mechanism 1 through the transmission assembly 21 to the universal joint and finally reaching the spiral shaft 311. The second transmission belt 34 is also made of high-strength and wear-resistant materials such as rubber and polyurethane to ensure stable transmission performance under long-term and high-load working conditions.

[0086] During the working process, the driving mechanism 1 first transmits the power to an intermediate position through the transmission assembly 21 (which may include components such as a first pulley 211, a first transmission belt 212, and a transmission shaft 213). Then, the power at this intermediate position is transmitted to the second pulley 33 through the second transmission belt 34. The second pulley 33 is then connected to the universal joint to transmit the power to the spiral shaft 311.

[0087] In some embodiments, as Figures 1 to 3 shown, the scallion soil covering device further includes: a frame 4 and a braking mechanism 5. The driving mechanism 1 is connected above the frame 4, and the rotary tillage mechanism 2 and the soil covering mechanism 3 are connected below the frame 4; the braking mechanism 5 is connected to the frame 4, and the braking mechanism 5 extends to the transmission assembly 21 for controlling the on / off of power transmission of the transmission assembly 21.

[0088] Specifically, the frame 4 is the basic support structure of the entire green onion soil-raising device, which connects and supports various components such as the driving mechanism 1, the rotary tillage mechanism 2, the soil-raising mechanism 3 and the brake mechanism 5. The design of the frame 4 needs to take into account factors such as the weight distribution, working stability and portability of the entire device. It is usually made of sturdy and durable materials such as steel or aluminum alloy to ensure that the device can still maintain a stable operating state under a long-term, high-intensity working environment. The driving mechanism 1 is the power source of the entire green onion soil-raising device. It is connected to the top of the frame 4 and provides rotational power through a motor or other power source. The driving mechanism 1 transmits power to the rotary tillage mechanism 2 and the soil-raising mechanism 3 through a transmission assembly 21 so that they can work normally. The rotary tillage mechanism 2 and the soil-raising mechanism 3 are connected to the bottom of the frame 4, and are responsible for soil cultivation and soil-raising work respectively. The rotary tillage mechanism 2 crushes the soil by rotating the blade to prepare for soil-raising work; and the soil-raising mechanism 3 transports the soil to the root of the green onion for soil-raising through components such as the spiral shaft 311. The design of these two mechanisms needs to be closely coordinated to ensure the smoothness and efficiency of the entire soil-raising process. The brake mechanism 5 is connected to the frame 4 and extends to the transmission assembly 21. Its main function is to control the on and off of the power transmission of the transmission assembly 21. By operating the brake mechanism 5, the working state of the rotary tillage mechanism 2 and the soil-raising mechanism 3 can be flexibly controlled to realize functions such as starting, stopping or adjusting the working speed. In practical applications, the brake mechanism 5 may use an electromagnetic brake, a hydraulic brake or other types of brake devices to realize the control of the transmission assembly 21.

[0089] In this embodiment, Figures 1 to 3 As shown, the brake mechanism 5 includes: a handle 51, a handrail 52, a brake rod 53 and a brake handbrake 54. The handle 51 is connected to the frame 4 through the handrail 52; the brake rod 53 is arranged on one side of the transmission assembly 21; the brake handbrake 54 is arranged on one side of the handle 51, and the brake handbrake 54 is connected to the brake rod 53 through a brake line, so as to control the position of the brake rod 53 through the brake handbrake 54, and control the on and off of the power transmission of the transmission assembly 21.

[0090] In this embodiment, the handle 51 is the part that the user directly holds when operating the brake mechanism 5. Its design needs to take ergonomics into consideration to ensure that the user can comfortably hold and control the device. The handle 51 is connected to the frame 4 through the handrail 52, and the user can conveniently control the entire brake mechanism 5 through the handle 51.

[0091] The brake lever 53 is arranged on one side of the transmission assembly 21 and directly acts on a key position of the transmission assembly 21 to control the on / off of power transmission. When the brake lever 53 is in the braking position, it will prevent the rotation of the transmission assembly 21, thus cutting off the power transmission; when the brake lever 53 is in the non-braking position, the transmission assembly 21 is allowed to rotate normally and the power is transmitted. The brake handbrake 54 is a component for the user to control the position of the brake lever 53. It is arranged on one side of the grip 51, facilitating the user to operate while holding the grip 51. The brake handbrake 54 usually has an operable lever or knob, and the user generates braking force by pushing or rotating this lever / knob. The brake cable serves as a transmission element connecting the brake handbrake 54 and the brake lever 53, transmitting the braking force generated on the brake handbrake 54 to the brake lever 53. When the user operates the brake handbrake 54, the brake cable will tighten or loosen accordingly, thereby changing the position of the brake lever 53 to achieve the on / off control of power transmission.

[0092] When the user needs to stop the operation of the green onion soil covering device, just hold the grip 51 tightly and operate the brake handbrake 54. After the lever / knob of the brake handbrake 54 is pushed / rotated, the braking force is transmitted to the brake lever 53 through the brake cable. Under the action of the braking force, the brake lever 53 moves to the braking position, preventing the rotation of the transmission assembly 21, thus cutting off the power transmission. At this time, the rotary tillage mechanism 2 and the soil covering mechanism 3 will stop working. When the user needs to restart the device, just loosen the brake handbrake 54. Under the action of the reset mechanism, the brake lever 53 returns to the non-braking position, the transmission assembly 21 resumes rotation, and the power is transmitted again.

[0093] In some embodiments, such as Figures 1 to 3 shown, the drive mechanism is a gasoline engine or a diesel engine.

[0094] The selection of the drive mechanism mainly depends on specific requirements, working environment, and expected usage frequency. Diesel engines usually provide greater torque and power, and are suitable for working environments that require stronger tillage force, such as hard soil or clay soil. Gasoline engines are light and flexible, easier to start, and more suitable for light to medium tillage and relatively soft soil. Although diesel engines have a higher initial investment, their fuel efficiency is usually better than that of gasoline engines, and the long-term operating cost is lower. If used frequently, diesel engines may be more economical. The fuel cost of gasoline engines is relatively high, but the price of the equipment itself and the maintenance cost may be lower. Gasoline engines are easy to start, have less noise, and are relatively simple to maintain. Although diesel engines may be slightly more complicated to start, their durability and failure rate are usually better than those of gasoline engines.

[0095] Table 1 Basic parameters of the engine

[0096]

[0097] The selection of the engine also needs to consider air-cooling and water-cooling. Air-cooled engines are easy to maintain and do not require coolant, but may need to stop more frequently to dissipate heat in high-temperature environments. Water-cooled engines can better maintain a constant temperature and are suitable for long-term continuous operation, but they have a more complex structure and higher maintenance requirements. In mountainous or hilly areas, lightweight gasoline engines are easier to carry and operate. In flat and open areas, the powerful power of diesel engines is more suitable. Considering the soil conditions, earthing-up requirements of scallion planting and the working environment of the earthing-up device, it is more appropriate to select an air-cooled gasoline engine for this design.

[0098] In specific embodiments, the currently available engine models for micro-tilling and earthing-up on the market include Honda GXV160 gasoline engine, GCV135 gasoline engine, Komatsu gasoline engine 170F, etc. The parameter comparison between Honda GXV160 gasoline engine and Komatsu gasoline engine 170F is shown in Table 1.

[0099] From the parameter information, it can be seen that Honda GXV160 adopts a single-cylinder four-stroke design and is equipped with a forced air-cooling system, ensuring efficient heat management and durable operating performance. It optimizes fuel efficiency, reduces fuel consumption while ensuring power, lowers operating costs, and meets environmental protection emission standards. It is convenient for daily maintenance and repair, and it is relatively easy to replace parts. User manuals and spare parts are abundantly available in the market. Honda GXV160 gasoline engine is favored by many users for its high efficiency, durability and versatility. Combining the operation requirements of scallion earthing-up in this design, the economic budget of scallion planting benefits, operating habits and the specific conditions of the region where it is located, this device uses Honda GXV160 gasoline engine as the driving mechanism for this embodiment.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
