Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary tiller technology, and in particular to a multi-functional integrated device based on a rotary tiller. Background Technology
[0002] Rotary tillers are indispensable and crucial pieces of machinery in agricultural production, playing a multifaceted and vital role. Through rotating blades, they efficiently break down and loosen the soil, crushing large clods into fine, uniform particles. This significantly improves soil porosity and aeration, creating an ideal seedbed environment for seed germination and facilitating seedling emergence. It also allows crop roots to extend more effectively and absorb water and nutrients. Simultaneously, rotary tillers level the land, optimizing irrigation and drainage, and preventing uneven distribution of waterlogging. In weeding and stubble removal, rotary tillers shred weeds by the roots and mix them into the soil, reducing competition for resources between weeds and crops. They also shred crop residues and bury them deeply, preventing the growth of pests and diseases. Furthermore, the decomposition of crop residues increases soil organic matter and improves soil structure. In fertilization, rotary tillers thoroughly mix fertilizer with the soil, ensuring even distribution in the tillage layer. This avoids fertilizer concentration leading to waste or burning of seedlings, enhances the soil's ability to absorb and retain nutrients, and ensures crops receive a continuous and balanced supply of nutrients. In addition, rotary tillers can break up the plow pan, enhance the soil's water retention capacity, and turn deep soil nutrients to the surface. Their high-efficiency operation can greatly improve agricultural production efficiency, reduce farmers' labor intensity, shorten land preparation time, and create favorable conditions for timely sowing and field management of crops.
[0003] When planting crops such as rice and vegetables after the land needs to be broken up, the land needs to be watered after breaking up the land. Because crops such as rice and vegetables require a large amount of water, water needs to be pumped from the well to irrigate the cultivated land after breaking up the land. However, pumping water from the well requires the use of a water pump. The water pump and the equipment that drives the water pump are heavy and take up a certain amount of space, which makes it inconvenient for farmers to carry when they travel to cultivate the land.

[0035] To combine tillage, power generation, and irrigation functions, and expand the applicable scenarios of rotary tillers, this embodiment provides a multi-functional integrated device based on a rotary tiller. The following describes the details... Figures 1 to 5 The specific content of this embodiment will be described in detail. It should be noted that the first direction mentioned in this embodiment is... Figure 1 The X direction in the equation.
[0036] This embodiment provides a multi-functional integrated device based on a rotary tiller, comprising a rotary tiller, a generator 5, a first transmission assembly, a transmission coupling shaft 8, and a peristaltic pump 6. These components work together to achieve multiple functions, including soil pulverization, power generation, and irrigation. The rotary tiller, as the foundation of the entire device, undertakes the primary task of soil pulverization. The rotary tiller includes rotary blades 1, a transmission shaft 2, and a housing 3. The transmission shaft 2 is rotatably mounted inside the housing 3, providing stable support for the rotation of the rotary blades 1. The rotary blades 1 are securely fixed to the transmission shaft 2 and rotate synchronously with it. The transmission shaft 2 is connected to the tractor's engine. When the tractor starts its engine, power is transmitted to the rotary blades 1 via the transmission shaft 2, enabling the blades to rotate rapidly and efficiently pulverize the soil. This design allows the rotary tiller to adapt to the cultivation needs of different types of land, whether soft farmland or relatively firm soil, achieving ideal soil pulverization results by adjusting the engine speed and the torque of the transmission shaft 2. Generator 5 is mounted on the outer casing 3 of the rotary tiller. A first internal gear sleeve 7 is coaxially mounted on the rotating shaft of generator 5. A support 22 is mounted on the outer casing 3, and the support 22 and generator 5 are spaced apart along a first direction, providing a reasonable spatial layout for subsequent power transmission and component installation. As the energy conversion core of the entire device, generator 5 can convert mechanical energy into electrical energy. During the operation of the rotary tiller, the power of the rotary tiller is transmitted to generator 5 through a specific transmission structure, causing the rotating shaft of generator 5 to rotate and thus generate electrical energy. This design makes full use of the mechanical energy of the rotary tiller during operation, avoids energy waste, and achieves efficient energy utilization. The first transmission component is the key link in realizing power transmission. The first transmission component includes a first sprocket 15, a second sprocket 10, a first chain, and a second internal gear sleeve 16. One end of the second internal gear sleeve 16 is rotatably mounted on the support 22, and the other end of the second internal gear sleeve 16 is fixedly inserted through the center of the first sprocket 15, ensuring that the first sprocket 15 and the second internal gear sleeve 16 can rotate synchronously. The first sprocket 15, the second internal gear sleeve 16, and the first internal gear sleeve 7 are located on the same axis. This coaxial design ensures the smoothness and accuracy of power transmission. The second sprocket 10 is fixedly sleeved on one end of the drive shaft 2 extending out of the housing 3, and the first chain is wound around the first sprocket 15 and the second sprocket 10. When the drive shaft 2 rotates, the first chain drives the first sprocket 15 to rotate, thereby transmitting power to the second internal gear sleeve 16. This chain drive method has the advantages of accurate transmission ratio, high transmission efficiency, and simple structure, and can effectively transmit the power of the rotary tiller to the generator 5 to realize the power generation function. The outer wall surface of the transmission insertion shaft 8 is provided with multiple limiting teeth in the circumferential direction. This design allows the transmission insertion shaft 8 to achieve precise insertion and engagement with the second internal gear sleeve 16 and the first internal gear sleeve 7.The transmission coupling shaft 8 can be inserted into the second inner gear sleeve 16 and the first inner gear sleeve 7 along the first direction. When inserted into place, the limiting teeth mesh with the teeth inside the inner gear sleeve, thus achieving reliable power transmission. When power transmission is not required, the transmission coupling shaft 8 can be simply pulled out from the second inner gear sleeve 16 and the first inner gear sleeve 7 to cut off power transmission. This operation is convenient and quick, greatly improving the flexibility of the device. The peristaltic pump 6 is also installed on the outer casing 3 of the rotary tiller. The motor of the peristaltic pump 6 is connected to the generator 5 via a wire. The peristaltic pump 6 is a special fluid transport device that transports liquid through peristaltic movement within the pump tube. In this device, the peristaltic pump 6 is mainly used for pumping water for irrigation. When the generator 5 generates electrical energy, it supplies power to the motor of the peristaltic pump 6 via a wire, enabling the peristaltic pump 6 to operate normally. This design organically combines power generation and irrigation functions, achieving energy self-sufficiency and providing convenience for irrigation operations in agricultural production.
[0037] In short, in practical use, when this multi-functional integrated device needs to be used for tillage operations, simply install the rotary tiller on the tractor and have the engine drive the rotary tiller blades 1 to rotate rapidly via the drive shaft 2. Due to the reasonable design of the rotary tiller blades 1, they can be appropriately adjusted according to different soil conditions, such as the number, shape, and installation angle of the blades, allowing the rotary tiller blades 1 to fully utilize their soil-tillage capabilities during high-speed rotation. Whether it's a large area of farmland or a small vegetable patch, tillage operations can be completed in a short time, greatly improving the efficiency of agricultural production. At the same time, the rotary tiller's outer casing 3 effectively protects the internal transmission components, preventing soil and debris from entering and extending the equipment's service life. The generator 5 and peristaltic pump 6 are both installed on the rotary tiller's outer casing 3; this integrated design makes the entire device compact and space-saving. The second sprocket 10 of the first transmission component is fixedly mounted on the rotary tiller's drive shaft 2, and power transmission between the first sprocket 15 of the first transmission component and the generator 5 is achieved through the transmission connector shaft 8. When the rotary tiller is working, the drive shaft 2 drives the second sprocket 10 to rotate, transmitting power to the first sprocket 15 via the first chain. This, in turn, causes the rotating shaft of the generator 5 to rotate, generating electricity. This power generation method does not require an external power source, fully utilizing the mechanical energy of the rotary tiller during operation and achieving energy self-sufficiency. The electrical energy generated by the generator 5 can not only power the peristaltic pump 6 but can also be stored in the battery for use by other equipment. For example, it can power lighting equipment during nighttime operations; and it can also draw power from the battery when other electric agricultural implements are needed, improving energy utilization efficiency.
[0038] When irrigation is needed, simply connect the inlet of the peristaltic pump 6 to a water pipe and extend it into the well, and connect the outlet to a water pipe and extend it into the farmland. Since the motor of the peristaltic pump 6 is powered by the generator 5, there is no need to carry an additional water pump or drive equipment to power it, greatly reducing the labor intensity of farmers. At the same time, the peristaltic pump 6 has advantages such as adjustable flow rate and pollution-free liquid delivery, allowing the flow rate to be adjusted according to different irrigation needs, ensuring uniform irrigation of the farmland. Furthermore, the device is highly mobile, able to move with the rotary tiller between different plots, facilitating irrigation of farmland in different locations and improving the flexibility and efficiency of irrigation operations.
[0039] When irrigation and power generation are not required, the power transmission can be cut off simply by pulling the drive coupling shaft 8 out of the second inner gear sleeve 16 and the first inner gear sleeve 7. This design makes the operation of the device more flexible and convenient, allowing farmers to turn the power generation and irrigation functions on or off at any time according to actual production needs. For example, when irrigation is needed during drought, the drive coupling shaft 8 can be inserted to start the power generation and irrigation functions; when irrigation is not needed during the rainy season, the drive coupling shaft 8 can be pulled out, allowing the rotary tiller to focus on tilling operations, thus improving the adaptability and practicality of the device.
[0040] Furthermore, to achieve precise control over the insertion depth of the transmission coupling shaft 8, a limiting plate 17 is specially provided at one end of the transmission coupling shaft 8. The outer diameter of the limiting plate 17 is strictly set to be larger than the inner diameter of the second internal gear sleeve 16. This design ensures that when the transmission coupling shaft 8 is inserted into the second internal gear sleeve 16, the limiting plate 17 will naturally stop when it reaches the end position of the second internal gear sleeve 16, thereby effectively limiting the insertion depth of the transmission coupling shaft 8 into the second internal gear sleeve 16. This precise limitation on the insertion depth has several important implications. First, it ensures that the fit between the transmission coupling shaft 8 and the second internal gear sleeve 16 is in the optimal state. If the insertion depth is too deep, it may cause excessive friction between the transmission coupling shaft 8 and the second internal gear sleeve 16, increasing energy loss during transmission, reducing transmission efficiency, and even potentially causing overheating and damaging components; while if the insertion depth is too shallow, sufficient power transmission torque cannot be guaranteed, and slippage may easily occur, affecting the stability and reliability of the transmission. The precise positioning of the limiting plate 17 avoids the aforementioned problems, ensuring the transmission system maintains a highly efficient and stable operating state. Secondly, the limiting plate 17 significantly simplifies the assembly process. In traditional transmission assembly, operators rely on experience and visual inspection to determine the insertion depth of the transmission coupling shaft 8, which is prone to errors and inefficient. With the precise positioning of the limiting plate 17, operators only need to insert the transmission coupling shaft 8 into the second inner gear sleeve 16 until the limiting plate 17 stops, eliminating the need for complex depth measurements and adjustments. This significantly improves assembly accuracy and efficiency, while reducing assembly difficulty and labor intensity.
[0041] To further enhance the ease of operation for the operator using the transmission connector shaft 8, a handle 23 is provided at the end of the limiting plate 17 furthest from the transmission connector shaft 8. This design fully considers ergonomic principles, making it easier and more comfortable for the operator to manually pick up and push the transmission connector shaft 8. The operator only needs to hold the handle 23 to easily operate the transmission connector shaft 8 without directly contacting other parts of the shaft, avoiding safety accidents and operational errors caused by hand slippage or inconvenience. Furthermore, to enhance the anti-slip performance of the handle 23, an anti-slip structure is provided on its surface. The anti-slip structure can take various forms, including but not limited to anti-slip grooves, anti-slip protrusions, and anti-slip textures. Anti-slip grooves, created by recesses of a certain depth and width on the surface of the handle 23, increase the friction between the hand and the handle 23, making the grip more secure for the operator. Anti-slip protrusions, with raised particles or stripes on the surface of the handle 23, further increase the roughness of the contact surface and improve the anti-slip effect. Anti-slip patterns, using special texture designs such as grid patterns and wave patterns, not only provide excellent anti-slip performance but also enhance the aesthetics of the handle 23. The application of these anti-slip structures effectively solves the problem of operator hands easily slipping in harsh environments such as wet or oily conditions, greatly improving operational safety and reliability. Whether in normal operation or in emergency situations requiring adjustment or disassembly of the transmission coupling shaft 8, the operator can firmly grip the handle 23, accurately and quickly completing various operational tasks, ensuring the normal operation of the entire transmission system and the smooth progress of the production process.
[0042] Furthermore, in the refined design of the first transmission component, a key component, the first protective housing 14, was specially added to comprehensively improve its operational stability and reliability. The first protective housing 14 is securely connected to the side wall of the outer shell 3 via a connecting structure. The connection method may employ various forms such as bolt fastening, slot nesting, or welding, with the specific choice determined based on factors such as the actual usage scenario, material properties, and ease of installation, to ensure a tight and reliable integration between the first protective housing 14 and the outer shell 3. Structurally, the first sprocket 15, the second sprocket 10, and the first chain are all housed within the internal space of the first protective housing 14. In the specific working condition of soil pulverization, the soil environment is extremely complex, containing numerous clods of soil, stones, and other hard objects of varying sizes. During the operation of the soil pulverizing equipment, these hard objects are highly likely to be scattered due to centrifugal force or mechanical vibration. Without the protection of the first protective housing 14, the first sprocket 15, the second sprocket 10, and the first chain would be directly exposed to this harsh environment. Splashed soil or hard objects can cause varying degrees of damage to the sprocket teeth or chain links when they impact them. For example, it may cause wear, deformation, or even breakage of the sprocket teeth, leading to inaccurate meshing between the sprocket and chain, resulting in vibration and noise during transmission, severely affecting the smoothness of the transmission. For the chain, impacts from hard objects may loosen or break chain links, or disrupt the chain's lubrication, accelerating wear and shortening its lifespan. However, the situation is completely different after adding the first protective sleeve 14. The first protective sleeve 14 acts as a robust barrier, completely isolating the first sprocket 15, the second sprocket 10, and the first chain from external soil and hard objects. During soil breaking, no matter how much soil and hard objects splash, they cannot directly contact these critical transmission components, effectively preventing them from being interfered with or damaged. This not only ensures that the first sprocket 15, the second sprocket 10, and the first chain can always operate normally in a good working environment, ensuring transmission accuracy and efficiency, but also greatly reduces equipment downtime and maintenance time due to component damage, improving the overall reliability and production efficiency of the soil crushing equipment. Furthermore, the first protective casing 14 also has dustproof and waterproof functions. During soil crushing operations, a large amount of dust is generated. If this dust enters the first transmission assembly, it will adhere to the surfaces of the sprockets and chain, affecting lubrication and accelerating wear. Simultaneously, in rainy weather or when the equipment is being cleaned, without protective measures, moisture may also enter the transmission assembly, leading to rust and corrosion. The first protective casing 14 effectively prevents dust and moisture from entering, providing a relatively clean and dry working environment for the first transmission assembly, further extending its service life and reducing equipment maintenance costs.
[0043] Furthermore, the multi-functional integrated device based on the rotary tiller also includes a second transmission assembly. One end of the second transmission assembly is connected to the tractor's engine, and the other end is connected to the drive shaft 2. This establishes a complete and smooth power transmission channel, ensuring that the powerful force generated by the engine can be smoothly transmitted to the corresponding working parts of the rotary tiller. Further, the second transmission assembly includes an input shaft 12, a third sprocket 9, a fourth sprocket 13, and a second chain. The third sprocket 9 is securely fixed to the middle section of the drive shaft 2. This fixing method typically employs high-precision key connections or interference fits to ensure that the third sprocket 9 and the drive shaft 2 can rotate synchronously without relative slippage during transmission, thus ensuring the accuracy and stability of power transmission. The fourth sprocket 13 is rotatably mounted on the housing 3 (supported by high-precision bearings, allowing the fourth sprocket 13 to rotate flexibly and smoothly under the drive of the second chain, while the bearings effectively reduce frictional resistance during rotation and lower energy loss). As a key component for power input, the input shaft 12 has one end coaxially connected to the fourth sprocket 13. This coaxial connection ensures that the rotation centers of the input shaft 12 and the fourth sprocket 13 are completely aligned, avoiding additional vibration and noise caused by eccentricity and further improving the smoothness of transmission. The other end of the input shaft 12 is used for transmission connection with the tractor's engine (usually using a coupling or spline connection to adapt to different structures and speed requirements of the engine output shaft, ensuring that power can be efficiently and reliably transmitted from the engine to the input shaft 12). The second chain is wound around the third sprocket 9 and the fourth sprocket 13, forming a closed transmission circuit. When the tractor's engine starts and runs, its output shaft drives the input shaft 12 to rotate, and the input shaft 12 then transmits power to the coaxially connected fourth sprocket 13. During rotation, the fourth sprocket 13 transmits power to the third sprocket 9 via the second chain. The third sprocket 9 is fixedly connected to the drive shaft 2, thereby driving the drive shaft 2 to rotate and ultimately transmitting the engine's power to the corresponding working parts of the rotary tiller, achieving rotary tillage. The use of chain drive offers numerous significant technical benefits and advantages. First, chain drive has an accurate average transmission ratio, maintaining stable transmission performance over a long service life, unlike belt drive which is prone to slippage. This ensures that the tractor engine's power is accurately transmitted to the rotary tiller's drive shaft 2, allowing the rotary tiller to operate at the predetermined speed and torque, improving the quality and efficiency of rotary tillage. Second, chain drive has a relatively compact structure and occupies less space, which is particularly important for agricultural machinery like rotary tillers that require multiple components to be arranged within a limited space. The compact design not only helps reduce the overall size of the rotary tiller, improving its maneuverability and flexibility, but also facilitates the installation, commissioning, and maintenance of the equipment.Furthermore, chain drives can operate normally in harsh working environments such as high temperature, humidity, and dust, demonstrating strong adaptability and reliability. In agricultural operations, rotary tillers often encounter various complex conditions, such as muddy soil and flying dust. The sprockets and chains of chain drives are typically made of high-strength alloy materials and undergo special surface treatment, resulting in excellent wear resistance, corrosion resistance, and fatigue resistance. This allows for long-term stable operation in harsh environments, reducing equipment failure rates and maintenance costs, and extending the equipment's service life.
[0044] Furthermore, the second transmission assembly also includes a second protective housing 11, which is connected to the top wall of the outer casing 3 and will not loosen or fall off due to mechanical vibration or external impact. The third sprocket 9, the fourth sprocket 13, and the second chain are all located within the second protective housing 11. By adding the second protective housing 11, the reliability of the second transmission assembly is greatly improved. Because it avoids impacts and interference from external hard objects, the wear rate of the sprockets and chains is significantly reduced, and the failure rate is greatly decreased. This allows the second transmission assembly to maintain stable performance for a longer period, reducing downtime for maintenance due to equipment failure and improving the overall working efficiency of the rotary tiller. Secondly, the second protective housing 11 helps extend the service life of the second transmission assembly. In a good protective environment, the materials of the sprockets and chains can better maintain their physical and chemical properties, and are less prone to aging and corrosion. This not only reduces equipment replacement costs but also reduces resource waste, conforming to the concept of sustainable development. In addition, the second protective housing 11 also provides a certain degree of dust and water protection. During soil breaking operations, a large amount of dust is generated. If this dust enters the second transmission assembly, it will adhere to the surfaces of the sprockets and chains, affecting their lubrication and accelerating wear. The second protective sleeve 11 can block most of the dust from entering, keeping the transmission components clean. At the same time, in rainy weather or when the equipment is being cleaned, the second protective sleeve 11 can also prevent moisture from entering, avoiding rust and corrosion of the sprockets and chains, further ensuring the normal operation of the second transmission assembly.
[0045] Furthermore, the multi-functional integrated device based on the rotary tiller also includes a lifting component, which includes a support 4. One end of the support 4 is hinged to the outer casing 3, and the other end of the support 4 is used to insert into the ground (the sharp end of the support 4 can easily penetrate soils of various hardnesses, such as loose cultivated soil and relatively firm field ridge soil, providing a stable support point for the entire lifting component). In practical applications, when the rotary tiller needs to perform non-rotary tillage tasks such as pumping water and generating electricity, the unique function of the lifting component is fully demonstrated. The operator only needs to easily erect the support 4. During the erection process, due to its hinged relationship with the outer casing 3, the support 4 will move in an arc around the hinge point, gradually lifting the entire rotary tiller. As the support 4 is erected, the distance between the rotary tiller blades 1 and the ground increases, eventually causing the rotary tiller blades 1 to be completely away from the ground. First, from a safety perspective, keeping the rotary tiller blades 1 away from the ground effectively avoids safety accidents caused by the rotary tiller blades 1 accidentally touching the ground or other obstacles during operations such as pumping water and generating electricity. For example, during water pumping operations, if the rotary tiller blades 1 remain in contact with the ground, vibrations from the pump or movement of the equipment may cause them to collide with hard objects such as stones and tree roots, generating flying debris that could injure nearby operators. By lifting the rotary tiller blades 1 off the ground, this safety hazard is completely eliminated, providing operators with a safe and reliable working environment. Secondly, from an equipment protection perspective, lifting the rotary tiller blades 1 off the ground avoids prolonged contact with soil, water, and corrosive substances in the farmland. During rotary tilling, the blades 1 constantly rub against the soil, causing surface wear. Simultaneously, moisture and fertilizers in the soil accelerate corrosion. During pumping and power generation operations, if the rotary tiller blades 1 are not lifted, these harmful factors will continue to damage them, shortening their lifespan. Lifting the rotary tiller blades 1 by the lifting assembly effectively reduces wear and corrosion, lowers equipment maintenance costs, extends the blades' lifespan, and improves the overall economy of the rotary tiller. Furthermore, from an operational efficiency perspective, the lifting component allows the rotary tiller to quickly switch to pumping and power generation modes without disassembling the rotary blades 1. If different functions are required, it often necessitates disassembling and replacing the corresponding working parts, a process that is not only time-consuming and labor-intensive but also prone to damage due to improper operation. However, with the lifting component integrated into the multi-functional rotary tiller, operators can easily switch operating modes in a short time by simply manipulating the support 4, significantly improving operational efficiency, reducing equipment downtime, and enabling the rotary tiller to fully leverage its multi-functional advantages to meet the diverse needs of modern agricultural production.
[0046] Furthermore, the outer casing 3 is provided with a mounting base 18. The surface of the mounting base 18 undergoes fine processing, such as polishing and spraying with anti-rust paint, which not only improves its appearance quality but also enhances its corrosion resistance and wear resistance, enabling it to be used for a long time without damage in harsh agricultural working environments. The middle section of the bracket 4 is detachably connected to the mounting base 18. When it is necessary to lift the rotary tiller, the connection between the middle section of the bracket 4 and the mounting base 18 becomes particularly important. At this time, the operator can easily and accurately insert the middle section of the bracket 4 into the mounting base 18. Due to the special shape design of the mounting base 18, the bracket 4 can quickly find a suitable position and achieve initial positioning. Subsequently, it is further fixed with fasteners such as bolts. For example, the mounting base 18 is carefully provided with a first connecting hole, and the middle section of the bracket 4 is correspondingly provided with a second connecting hole. The position and size of the second connecting hole strictly correspond to the first connecting hole. The operator only needs to pass the bolts or other fasteners through the second connecting hole and the first connecting hole in sequence, and then tighten the nut to make the bracket 4 and the mounting base 18 tightly connected together. This connection method can withstand significant tensile and shear forces, effectively ensuring the stability of the connection between the outer casing 3 and the support 4. During the lifting of the rotary tiller, even under significant external forces, such as the tiller's own weight or ground reaction forces, the connection between the support 4 and the mounting bracket 18 will not loosen or detach, ensuring the safety and reliability of the entire lifting process. Similarly, when it's time to lower the rotary tiller, detaching the middle section of the support 4 from the mounting bracket 18 is quick and easy. Operators simply need to use appropriate tools, such as wrenches, to loosen the nuts and remove the bolts and other fasteners to easily separate the middle section of the support 4 from the mounting bracket 18. This detachable connection method makes switching between different operating modes of the rotary tiller more efficient, significantly saving time and labor costs.
[0047] Furthermore, the lifting assembly also includes a load-bearing plate 19 with a load-bearing shovel 20. As a crucial component of the system, the load-bearing plate 19 is typically made of high-strength, high-rigidity metal sheet, such as high-quality alloy steel. This material possesses excellent resistance to bending and deformation, enabling it to withstand the immense pressure generated during the operation of the rotary tiller. The load-bearing plate 19 is hinged to the other end of the support 4, allowing it to rotate flexibly around the hinge point to adapt to different terrains and operational needs. The bottom surfaces of the load-bearing shovel 20 and the load-bearing plate 19 form a receiving groove, which can be filled with soil. The cutting edge of the load-bearing shovel 20 undergoes special quenching treatment, resulting in extremely high hardness, allowing it to easily cut into soils of varying hardness, whether loose cultivated soil or relatively firm field ridge soil. When the lifting assembly is in operation, the load-bearing plate 19 significantly increases the contact area with the ground. The large contact area of the load-bearing plate 19 distributes the weight of the rotary tiller more evenly across the ground, thus reducing the pressure per unit area. According to the pressure formula P = F / S (where P represents pressure, F represents force, and S represents the contact area), with a constant force F (i.e., the weight of the rotary tiller), increasing the contact area S effectively reduces the pressure P. This characteristic prevents the rotary tiller from sinking too deeply due to excessive pressure when operating on soft soil, ensuring normal operation and work quality. The load-bearing plate 19 increases the contact area with the ground. Simultaneously, the vibration generated by the engine during operation, combined with the deep-penetrating load-bearing shovel 20, reduces equipment displacement during operation. Furthermore, the trough formed by the load-bearing shovel 20 and the load-bearing plate 19 allows the equipment to easily bear its weight on soft soil. While strong vibrations from the engine during operation are unavoidable, the deep-penetrating design of the load-bearing shovel 20 cleverly solves the problem of equipment displacement. Once the load-bearing shovel 20 cuts into the soil, it forms a tight bond with the surrounding soil. The soil's inherent viscosity and friction provide strong resistance to the shovel 20. During equipment vibration, this resistance effectively counteracts the horizontal displacement forces caused by the vibration, significantly reducing the likelihood of displacement during operation. For example, in pumping or power generation operations, where the equipment needs to maintain a relatively stable position, this function of the load-bearing shovel 20 is particularly important, ensuring continuous and stable operation and improving operational accuracy and reliability. The receiving trough formed by the load-bearing shovel 20 and the load-bearing plate 19 plays a crucial role in supporting the entire equipment's load on soft, cultivated land. When the equipment is placed on soft, cultivated land, the soil naturally fills the receiving trough. Over time and with slight vibrations from the equipment, the soil gradually compacts, forming a tight bond with the load-bearing shovel 20 and the load-bearing plate 19.This composite structure, consisting of soil, a load-bearing shovel 20, and a load-bearing plate 19, can bear part of the equipment's weight, further enhancing its stability on soft ground. Simultaneously, the soil within the containment tank acts as a buffer, reducing the impact on the ground during equipment operation, protecting the soil structure, and preventing problems such as soil compaction due to excessive compaction.
[0048] Furthermore, supports 4 are provided on both sides of the outer casing 3. The lifting assembly includes a connecting frame 21, one end of which is connected to one of the supports 4, and the other end of which is connected to the other support 4. In the construction of the multi-functional integrated device based on the rotary tiller, the supports 4 are symmetrically arranged on both sides of the outer casing 3. This layout design lays a solid foundation for the lifting function of the entire device. The two supports 4 are not isolated, but are connected through the connecting frame 21 in the lifting assembly, jointly constructing a high-strength and high-stability structural system. As a key connecting component of the lifting assembly, the connecting frame 21 is designed with full consideration of mechanical principles and actual working conditions. It is usually made of high-strength alloy steel, which has excellent tensile strength, yield strength, and toughness, and can withstand the huge tensile, compressive, and bending forces generated by the rotary tiller during lifting and use. In this embodiment, the connecting frame 21 is arc-shaped. One end of the connecting frame 21 is connected to one of the supports 4 by a high-strength bolt. The high-strength bolt connection has the advantage of convenient installation and disassembly. The other end of the connecting frame 21 is connected to another support 4 in the same way, ensuring a firm connection between the two supports 4. Installing the connecting frame 21 between the two supports 4 brings significant and multifaceted technical benefits. From a structural strength perspective, the connecting frame 21 connects the two originally independent supports 4 into a whole, forming a frame structure. According to structural mechanics principles, a frame structure has high overall rigidity and strength, and can better resist external forces. During the rotary tiller's lifting process, the equipment's own weight and potential external impact forces are evenly distributed to the two supports 4 and the connecting frame 21, preventing individual supports 4 from deforming or being damaged due to excessive force. For example, when the rotary tiller is lifted on uneven ground, the ground reaction force will cause irregular vibrations and impacts on the equipment. Without the reinforcement of the connecting frame 21, the supports 4 may bend or break due to uneven local stress. The presence of the connecting frame 21 effectively disperses these forces, ensuring the overall structural integrity of the lifting assembly. In terms of support stability, the connecting frame 21 enhances the lifting assembly's support capacity for the entire equipment. The two supports 4 work together through the connecting frame 21 to form a stable support plane, which can more evenly distribute the weight of the equipment to the ground. This support method of double supports 4 plus connecting frame 21 greatly improves the stability of the equipment and reduces the possibility of tilting or swaying during lifting and use. Especially in operations such as pumping water and power generation, where the equipment needs to maintain a relatively stable state, the supporting role of the connecting frame 21 is particularly important. It can ensure that the equipment will not affect the quality of operation and the safety of the equipment due to swaying during long-term operation.
[0049] Optionally, the connecting frame 21 is provided with multiple weight-reducing holes at intervals. These weight-reducing holes come in various shapes, commonly including circular, elliptical, and oblong. Circular weight-reducing holes are simple to manufacture and have a relatively uniform stress distribution; elliptical and oblong weight-reducing holes can better adapt to the stress characteristics of the connecting frame 21 to a certain extent, reducing weight while minimizing adverse effects on structural strength. The even distribution and reasonable spacing of multiple weight-reducing holes ensure that the stress on all parts of the connecting frame 21 is uniform while reducing weight, and also avoids local stress concentration caused by excessively dense holes. The most direct technical effect of providing weight-reducing holes on the connecting frame 21 is a significant reduction in the weight of the connecting frame 21 itself. Since the connecting frame 21 is an important component of the lifting assembly, its weight reduction directly leads to a reduction in the overall mass of the device. For example, during field operations, operators need to frequently adjust the position and direction of the rotary tiller; a lighter device makes these operations easier and faster, greatly improving work efficiency. Reasonable placement of weight-reducing holes can also optimize the stress distribution of the connecting frame 21 and improve its mechanical properties. When the connecting frame 21 is subjected to external forces, the stress is transmitted and distributed within the structure. The presence of the weight-reducing holes alters the cross-sectional shape and stiffness distribution of the connecting frame 21, allowing the stress to be more evenly distributed throughout the structure and preventing localized stress concentration. Stress concentration is one of the main causes of structural fatigue failure. By setting weight-reducing holes, the risk of fatigue crack propagation caused by stress concentration in the connecting frame 21 during long-term use is effectively reduced, extending its service life. Simultaneously, the weight-reducing holes can also adjust the natural frequency of the connecting frame 21 to a certain extent, preventing resonance with the vibration frequency generated during equipment operation, reducing vibration damage to the connecting frame 21, and further improving the reliability and stability of the equipment. Compared to a solid connecting frame 21, the connecting frame 21 with weight-reducing holes uses less material, lowering manufacturing costs. Moreover, the weight-reducing holes can be easily achieved using common processing methods such as stamping and drilling, making the processing technology relatively simple and production efficiency high.
