Description

Technical Field

[0001] The present invention relates to the technical field of lubrication of agricultural machinery and equipment, and specifically to a fully connected oil passage circulating lubrication system for a transplanting device based on pressure control. Background Technique

[0002] In agricultural production, transplanting devices are widely used in the planting of seedlings, saplings, etc.; transplanting devices include many moving parts, such as transmission boxes, rotating boxes, and transplanting rods; the transmission box has to transmit power to the rotating box, and the rotating box in turn needs to drive the transplanting rod to perform high-frequency up and down transplanting actions; during the operation of these parts, friction will occur on the surfaces in contact with each other; without a lubrication system, the direct friction between metal surfaces will not only increase energy loss and reduce power transmission efficiency, but also increase the operating resistance of the equipment, resulting in the need for power sources such as motors to output greater power, causing energy waste. Therefore, a lubrication system is used.

[0003] Existing transplanting devices have some deficiencies in the transmission structure and lubrication system; for example, the layout of the transmission box and the rotating box is unreasonable, resulting in low power transmission efficiency; most lubrication systems adopt decentralized lubrication, which requires frequent greasing maintenance, increasing labor costs, and the lubrication effect is not good, easily causing wear of accessories and shortening the service life of the equipment. At the same time, it is difficult for traditional lubrication systems to ensure stable pressure in the oil passage, and negative pressure is likely to occur, resulting in foreign matter inhalation and affecting the normal operation of the equipment. Therefore, a fully connected oil passage circulating lubrication system for a transplanting device based on pressure control is proposed to solve the above-mentioned problems. Summary of the Invention

SPECIFIC EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 , a fully connected oil duct circulating lubrication system of a pressure-controlled transplanting device, including a transplanting part 1 and an oil duct circulating lubrication component. The structure of the transplanting part 1 includes a plurality of transmission boxes 3 and rotary boxes 2. The layout of the transmission boxes 3 and rotary boxes 2 is: rotary box 2, transmission box 3, rotary box 2, transmission box 3, rotary box 2, transmission box 3, etc. Different models of machines have different layouts and different numbers.

[0025] It should be noted that in agricultural production, transplanting equipment is widely used in the planting of seedlings, saplings, etc., and usually operates in open areas such as outdoor farmland. The terrain and soil conditions of farmland vary, and there may be situations such as undulations, mud, sand and stones, which pose relatively high requirements for the stability and durability of transplanting equipment. At the same time, the equipment needs to perform high-frequency up and down transplanting actions during operation; there are many moving parts, such as the transmission box 3, the rotating box 2, and the transplanting rod, etc.; the transmission box 3 needs to transmit power to the rotating box 2, and the rotating box 2 needs to drive the transplanting rod to perform high-frequency up and down transplanting actions; during the operation of these parts, friction will occur on the mutually contacting surfaces; without a lubrication system, the direct friction between metal surfaces will not only increase energy loss and reduce power transmission efficiency; therefore, it is necessary to lubricate the transplanting equipment through the set oil passage circulating lubrication components, so as to reduce the wear between parts, improve the service life of the equipment, reduce the maintenance and replacement costs of the equipment, and effectively improve agricultural production efficiency.

[0026] In this embodiment, on the main frame of the transplanting equipment, according to the designed layout plan, the transmission box 3 and the rotating box 2 are installed in sequence. From left to right, follow the layout sequence of "rotating box 2, transmission box 3, rotating box 2..."; for example, first fix the first rotating box 2 at the designated position on the frame through the supporting bolts and positioning pins to ensure its firm installation and accurate position. Then, install the adjacent first transmission box 3. By adjusting the connecting components between the two, such as couplings or chains, etc., ensure that the transmission box 3 can effectively transmit power to the rotating box 2. During the installation process, use professional measuring tools, such as spirit levels and calipers, to ensure that the levelness and perpendicularity errors of each transmission box 3 and rotating box 2 are controlled within the allowable range to ensure the smoothness of power transmission.

[0027] At the same time, after each rotating box 2 is installed in place, install the transplanting rod. Each rotating box 2 is equipped with two transplanting rods, and the transplanting rod is connected to the rotating box 2 through the rotating shaft and link mechanism inside the rotating box 2.

[0028] The oil passage circulating lubrication components include an orbital oil pipe 4, a delivery pipe 5, a main oil pipe 6, an oil pot 7, a filter 8, an oil-water separation device 9, an electronic pressure pump 10, a check valve 11, a pressure sensor 12, a shuttle switch 13, a relief valve 14, a gear pump and an oil filling filter element, and the oil passage circulating lubrication components are of an integrated design.

[0029] In this embodiment, a sealed oil pipe is used to connect the oil outlet of the oil pot 7 and the filter 8, and a pipe clamp is used for fastening to prevent leakage. An oil-water separation device 9 is connected behind the filter 8, and the installation position should be convenient for daily cleaning and maintenance. After installation, an appropriate amount of hydraulic oil is injected, and the connection is checked for leakage. The electronic pressure pump 10 is installed near the oil pot 7 and the filter 8. The electronic pressure pump 10 is connected to the track oil pipe 4 through a flange, ensuring that the gasket is intact, and the bolts are tightened evenly. Secondly, the track oil pipe 4 and the conveying pipeline 5 are connected by welding or a special joint, and strength and tightness tests are carried out. At the same time, the conveying pipeline 5 and the main oil pipeline 6 are connected. An adjustable valve is set at the connection between the main oil pipeline 6 and other oil pipes to facilitate the control of the oil flow rate and pressure. According to the oil flow direction, a one-way valve 11 is installed on the conveying pipeline 5, a pressure sensor 12 is installed in the immediately adjacent position behind the one-way valve 11, and a shuttle switch 13 is installed along the oil flow direction behind the pressure sensor 12. The overflow valve 14 is installed near the oil pot 7 on the main oil pipeline 6 and is connected by threading.

[0030] In this embodiment, the process of realizing lubrication is as follows:

[0031] Oil pretreatment: The hydraulic oil flowing out of the oil pot 7 first passes through the filter 8. The filtering medium (such as a filter screen) inside the filter 8 filters out impurities and particles in the oil, ensuring the cleanliness of the oil. Subsequently, the oil enters the oil-water separation device 9, which uses the pressure of the pressure pump to separate the water in the oil through methods such as pressure extrusion to prevent the water from affecting the lubrication effect.

[0032] Pressurized transportation: The pretreated oil enters the electronic pressure pump 10. The electronic pressure pump 10 is driven by electricity, converting mechanical energy into the pressure energy of the oil, enabling the oil to obtain sufficient pressure, and then transporting it to the main oil pipeline 6 through the track oil pipe 4 and the conveying pipeline 5.

[0033] Distributed lubrication: The main oil pipeline 6 located at the core part of the equipment distributes the oil to the oil channels of each transmission box 3, rotary box 2, and planting rod. During the operation of these components, the mutually contacting surfaces are covered with oil, forming a lubricating film, reducing the direct friction between metal surfaces, and achieving a good lubrication effect. During the oil circulation process, the one-way valve 11 ensures that the oil always flows in a predetermined direction, the pressure sensor 12 monitors the oil pressure, the shuttle switch 13 controls the on-off according to the oil flow state, and the overflow valve 14 ensures that the oil pressure in the main oil pipeline 6 is stable within a suitable range.

[0034] In this embodiment, lubrication can improve the power transmission efficiency, reduce the frictional resistance between components such as the transmission box 3 and the rotating box 2, make the power transmission smoother, and the power sources such as motors do not need to output excessive power, reducing energy consumption and improving the overall operation efficiency of the equipment; good lubrication can effectively reduce component wear, avoid equipment failures and damages caused by wear, extend the service life of each component of the equipment, and reduce the maintenance and replacement costs of the equipment.

[0035] At the same time, compared with the traditional decentralized lubrication that requires frequent greasing maintenance, this fully connected oil passage circulating lubrication system only needs simple maintenance operations such as regularly checking the oil level and replacing the filter element of the filter 8, greatly reducing the labor cost and maintenance time cost; components such as the pressure sensor 12 and the overflow valve 14 are used to stabilize the pressure in the oil passage, prevent foreign objects from being sucked in due to the generation of negative pressure, ensure the cleanliness of the internal structure of the equipment, maintain the stable operation of the equipment, reduce the downtime caused by equipment failures, and improve agricultural production efficiency.

[0036] In this embodiment, the reasonable layout of the transmission box 3 and the rotating box 2, combined with the fully connected oil passage circulating lubrication system, greatly reduces the frictional resistance between components, making the power transmission smoother; in terms of application scenarios, this system is not only applicable to centralized planting in large-scale farms, but also can well meet the diverse planting needs of small farmers; from the perspective of agricultural production sustainability, reducing equipment failures and downtime means that more planting tasks can be completed per unit time, improving land utilization rate, and at the same time reducing resource consumption caused by equipment maintenance and replacement, which has a positive significance for environmental protection and sustainable development.

[0037] In this embodiment, the innovation of the fully connected oil passage circulating lubrication system lies in that it breaks the decentralized pattern of the traditional lubrication system and forms a unified and efficient lubrication network, ensuring that every component that needs lubrication can be fully and evenly lubricated, further improving the overall performance of the equipment.

[0038] Therefore, this hydraulic oil lubrication system is not only applicable to the transplanting system. Its excellent performance and wide applicability also enable it to be applied to other agricultural machinery and equipment using traditional lubrication systems, providing efficient and stable lubrication guarantees for various agricultural machinery.

[0039] In summary, this fully connected oil passage circulating lubrication system for the transplanting equipment based on pressure control, through the reasonable layout of the transmission box 3 and the rotating box 2, combined with the fully connected oil passage circulating lubrication system, greatly reduces the frictional resistance between components, making the power transmission smoother, and the power sources such as motors do not need to output excessive power, effectively reducing energy consumption and improving the overall operation efficiency of the equipment. At the same time, good lubrication significantly reduces component wear, avoids equipment failures and damages caused by wear, thereby extending the service life of each component of the equipment and reducing the maintenance and replacement costs of the equipment.

[0040] Moreover, compared with the traditional decentralized lubrication that requires frequent greasing maintenance, this fully connected oil duct circulating lubrication system only needs simple maintenance operations such as regularly checking the oil level and replacing the filter element of the filter 8, which greatly reduces the labor cost and maintenance time cost. In addition, components such as the pressure sensor 12 and the overflow valve 14 work together to stabilize the pressure in the oil duct, prevent foreign objects from being inhaled due to the generation of negative pressure, ensure the cleanliness of the internal structure of the equipment, maintain the stable operation of the equipment, reduce the downtime caused by equipment failures, and effectively improve the agricultural production efficiency.
