Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a novel high-efficiency green onion harvesting device. Background Art

[0002] The green onion harvesting device is a mechanical device used for green onion harvesting, which mainly consists of the following parts: (1) Digging device: responsible for digging green onions out of the soil. Common types include plowshare type and rotary digging type. The plowshare type digging device cuts into the soil through the plowshare to dig out the green onions with the roots and soil; the rotary digging type uses a spiral excavation fork to rotate and drill into the soil to achieve the digging of green onions. (2) Clamping and conveying device: after the green onions are dug out, they are clamped and conveyed to ensure that the green onions can be smoothly moved from the digging position to the collection device. According to the different clamping methods, they can be divided into rigid clamping and flexible clamping. The rigid clamping and conveying device has a simple structure, but it is easy to damage the green onions; the flexible clamping and conveying device can better adapt to the shape and size of the green onions and reduce damage. (3) Soil cleaning device: used to remove the soil at the roots of the green onions for subsequent bundling and storage. Common soil cleaning methods include vibration soil cleaning and scraper soil cleaning, which remove the soil by vibration or scraping. (4) Collection device: Collect and sort the green onions after digging, clamping, conveying and soil cleaning for easy transportation and storage. The collection device generally includes a collection box, a conveyor belt, etc. The green onions are transported to the collection box or transferred to a designated storage location via a conveyor belt.

[0003] At present, most green onion harvesters use single-row or double-row harvesting methods, which have relatively low harvesting efficiency and are difficult to meet the needs of large-scale planting. Moreover, when harvesting in double rows, due to the structural limitations of the machine, the spacing between the two rows is not flexible enough to adjust, and it cannot adapt well to green onions with different planting densities. Frequent blockages affect progress: During the harvesting process, the problem of onion roots entangled and blocked is prone to occur, which not only reduces the transmission efficiency of the equipment, but also increases the risk of machine failure, further affecting the harvesting progress and increasing maintenance costs. Summary of the invention

[0004] In view of this, the technical problem to be solved by the present invention is: how to provide a new and efficient green onion harvesting device to improve the operating efficiency during the green onion harvesting process.

[0005] To achieve the above-mentioned purpose, the present invention provides a novel high-efficiency green onion harvesting device, which includes a frame, a driving wheel, a first transmission wheel, a second transmission wheel, a rotating wheel, a rotating shaft, a lever, and a rotating blade;

[0006] The driving wheel is arranged on the frame, the driving wheel is connected to the first transmission wheel, the first transmission wheel is connected to the second transmission wheel, the second transmission wheel is connected to the rotating wheel, the rotating wheels are respectively arranged at both ends of the rotating shaft, and the rotating shaft is rotatably connected to the frame;

[0007] The rotation of the driving wheel drives the rotating shaft to rotate through the transmission of the first transmission wheel, the second transmission wheel and the rotating wheel;

[0008] The shifting rod and the rotating blade are arranged on the rotating shaft.

[0009] Furthermore, the rotary blade includes a first blade and a second blade, and the first blade and the second blade are respectively arranged at two ends of the rotating shaft.

[0010] Furthermore, a plurality of the first blades are arranged at intervals along the axial direction of the rotating shaft, and the number of the first blades is greater than the number of the second blades.

[0011] Further, a gap is formed between the first blade and the second blade, and the shifting rod is arranged at a position between the first blade and the second blade.

[0012] Furthermore, the setting direction of the shifting rod is perpendicular to the axial direction of the rotating shaft, and a material hanging rod is arranged on the rotating shaft, and the material hanging rod and the shifting rod are respectively located on both sides of the rotating shaft.

[0013] Furthermore, a plurality of the shifting rods are spaced apart along the axial direction of the rotating shaft, a plurality of the material hanging rods are spaced apart along the axial direction of the rotating shaft, and a spacing dimension between adjacent shifting rods is greater than a spacing dimension between adjacent material hanging rods.

[0014] Compared with the related art, the invention proposes a novel and efficient green onion harvesting device, which has the beneficial effect that the setting of the first blade, the second blade and the lever significantly improves the harvesting efficiency. The first blades are spaced and distributed along the axis of the rotating shaft, and the number is greater than the second blades. When the rotating shaft rotates, the first blades cut into the soil over a large area and at a high frequency. With the advantage of quantity, the soil around the root of the green onion can be quickly loosened, the resistance of the green onion being pulled up can be reduced, and the green onion can be more easily separated from the soil environment. The second blade cooperates with the first blade to work in coordination from different positions, filling the "blind spot" of loosening the soil, so that the soil around the root of the green onion can be turned over more comprehensively and evenly, creating more favorable basic conditions for the subsequent pulling out of the green onion. The lever is located at a key position between the first blade and the second blade. When the green onion is initially loosened by the blade, the lever takes over. It can accurately pull the green onion plants out of the loosened soil, and push the green onions in an orderly manner to the predetermined collection direction with the appropriate spacing and angle settings, so as to avoid the green onions from being scattered randomly and reduce the time loss of subsequent manual secondary regularization. The three work together to loosen the soil, dig up the soil, and then straighten it out, all in one go, reducing jams and stagnation in the harvesting process, greatly shortening the harvesting time of a single green onion plant, and improving the overall efficiency of green onion harvesting. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of a novel high-efficiency green onion harvesting device in an embodiment of the present invention. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] See also Figure 1 As shown, the present invention provides a novel high-efficiency green onion harvesting device, which includes a frame 11, a driving wheel 12, a first transmission wheel 21, a second transmission wheel 22, a rotating wheel 13, a rotating shaft 14, a lever 33, and rotating blades.

[0018] The driving wheel 12 is arranged on the frame 11, the driving wheel 12 is connected to the first transmission wheel 21, the first transmission wheel 21 is connected to the second transmission wheel 22, the second transmission wheel 22 is connected to the rotating wheel 13, the rotating wheel 13 is respectively arranged at both ends of the rotating shaft 14, and the rotating shaft 14 is rotatably connected to the frame 11.

[0019] The rotation of the driving wheel 12 drives the rotating shaft 14 to rotate through the transmission of the first transmission wheel 21 , the second transmission wheel 22 and the rotating wheel 13 .

[0020] The driving wheel 12 is the starting input point of the power and is firmly placed on the frame 11. It is closely connected to the first transmission wheel 21. This connection method starts the first step of power transmission. The common connection forms are belt drive or chain drive. If belt drive is used, the belt has a certain elasticity and can buffer the impact of instantaneous overload, making the power transmission more stable; if chain drive is used, it can withstand greater tension, ensuring that the power is not interrupted and accurately transmitted during high-intensity operations.

[0021] The first transmission wheel 21 and the second transmission wheel 22 complete the relay and continuously transmit the power downward. The transmission principle between the two is similar to the first link, but there is a mystery in the size design. According to different transmission ratio requirements, their diameters will be carefully calculated. For example, when it is necessary to increase the speed of the shaft 14 and speed up the efficiency of the rotary blade loosening, the diameter of the first transmission wheel 21 will be reduced and the diameter of the second transmission wheel 22 will be increased, and the speed increase effect will be achieved by using the difference in wheel diameters. On the contrary, if you want to increase the torque and cope with relatively compact soil conditions, adjust the wheel diameter combination to reduce speed and increase torque.

[0022] The connection between the second transmission wheel 22 and the rotating wheel 13 is a key step in transmitting power to the rotating shaft 14. The rotating wheels 13 are located at both ends of the rotating shaft 14. This double-sided layout can evenly share the power, avoid bending and deformation caused by unilateral force on the rotating shaft, and ensure its stable rotation. The connection method can also be a belt or a chain. The precise adaptation of the tension is particularly important. If it is too loose, it is easy to slip and cause power loss. If it is too tight, it will aggravate the wear of the components and shorten the service life.

[0023] The rotating shaft 14 is provided with a lever 33 and a rotating blade. The rotating blade includes a first blade 31 and a second blade 32, and the first blade 31 and the second blade 32 are respectively arranged at both ends of the rotating shaft 14. A plurality of first blades 31 are arranged at intervals along the axis direction of the rotating shaft 14, and the number of the first blades 31 is greater than the number of the second blades 32.

[0024] A space is formed between the first blade 31 and the second blade 32 , and a lever 33 is provided at a position between the first blade 31 and the second blade 32 .

[0025] The plurality of first blades 31 are arranged at intervals along the axis direction of the rotating shaft 14, and the number of the first blades 31 is greater than the second blades 32. Driven by the driving wheel 12, the rotating shaft 14 is driven to rotate by the transmission system, and the first blades 31 rotate at a high speed, which can cut into the soil around the roots of the green onions in a large area and at a high frequency, effectively loosen the soil, and significantly reduce the adhesion between the roots of the green onions and the soil, creating favorable conditions for the subsequent smooth pulling of the green onions, and accelerating the green onion harvesting process.

[0026] The first blades 31 are intended to utilize the advantages of quantity and layout to solve the problem that the soil at the root of the green onion is difficult to loosen, quickly break the soil wrapping around the green onion, and improve the early efficiency of digging the green onion.

[0027] The first blade 31 is disposed at both ends of the rotating shaft 14. Although the number is small, they cooperate with the first blade 31 to fill the gap left by the first blade 31 when loosening the soil, thereby achieving a more comprehensive and uniform turning of the soil around the roots of the green onions, avoiding dead corners of soil loosening, and allowing the roots of the green onions to be effectively loosened in all directions, ensuring that the subsequent pulling action is continuous and smooth.

[0028] Among the key components of the green onion harvesting equipment, the blade layout on the rotating shaft 14 plays a decisive role, among which the first blade 31 is the most important.

[0029] From the perspective of the setting relationship, the first blades 31 are distributed at intervals along the axial direction of the rotating shaft 14. This kind of interval arrangement is by no means random, but a carefully considered mechanical design. It is distributed at one end of the rotating shaft 14 and cooperates with the second blade 32 at the other end. Multiple first blades 31 are arranged in sequence, and their number is deliberately set to be greater than the second blades 32. This difference in quantity lays the foundation for their different division of labor during loosening operations. In terms of spatial layout, a specific interval is left between the first blade 31 and the second blade 32, and the lever 33 is cleverly placed here to form a closely related mechanical structure system with the two.

[0030] The technical effect of the first blade 31 is remarkable. It is the pioneer force to solve the problem of loose soil at the roots of green onions. In actual operation, the driving wheel 12 drives the transmission system to cause the rotating shaft 14 to rotate at high speed. The first blade 31 then cuts into the soil around the roots of green onions at high speed like a sharp blade. Because it is arranged at intervals along the axis direction and there are a large number of them, its operation coverage area is very considerable. With each rotation, the numerous first blades 31 can contact the soil at a high frequency. The soil that was originally compacted and firmly attached to the roots of green onions quickly disintegrates and loosens under such high-frequency impact. The advantage of loosening the soil over a large area is fully demonstrated, which sharply reduces the adhesion between the roots of green onions and the soil, and tears the first hole for the subsequent easy pulling out of the green onions, greatly accelerating the early process of green onion harvesting.

[0031] Assuming that there is no advantage in the number and layout of the first blades 31, and only a small number of scattered digging parts are used, the efficiency of loosening the soil in the vast green onion field will be extremely low. It should be noted that the green onion planting density is relatively high, and the soil conditions at the roots are complex, which is difficult to cope with with traditional simple digging tools. The first blades 31 rely on dense layout, like a fine sieve, not letting go of any possible compacted soil blocks, quickly breaking the stubborn wrapping of the soil on the green onions, so that the initial stage of digging green onions can be efficiently promoted.

[0032] Although the second blades 32 are few in number, they play an indispensable auxiliary role. They are separated from the first blades 31 at both ends of the rotating shaft 14. After the first blades 31 loosen the soil vigorously, the second blades 32 strike accurately to fill the gap left by the first blades 31 during operation. The soil environment around the roots of green onions is not regular. Even if there are many first blades 31, it is inevitable that some corners are not fully turned over. The second blades 32 can just take care of these "blind spots" and achieve a more comprehensive and uniform turning of the soil around the roots of green onions. In this way, there are no dead corners for loosening the soil, and the roots of green onions can be effectively loosened in all directions. When pulling out the green onions later, the movements can be continuous and smooth, and there will be no jamming due to local hard soil blocks that have not been loosened, ensuring the seamless connection of the entire green onion harvesting process.

[0033] In addition, the lever 33 arranged perpendicular to the axis direction of the rotating shaft 14 and the hanging rod 34 located on the other side of the rotating shaft 14 together enrich the functionality of this mechanical structure. During the rotation of the rotating shaft, the lever 33 may also play a role in assisting in soil shifting and guiding the flow of soil, so as to prevent the accumulation of soil after loosening the soil from affecting the continued operation of the blades, and cooperate with the first blade 31 to continuously optimize the soil environment at the root of the green onion, so as to make the mechanical operation process of green onion harvesting more stable and efficient, and truly meet the urgent needs of the large-scale green onion planting industry for efficient harvesting equipment. In short, the setting relationship of the first blade 31 serves the technical effect, and the two together ensure the efficient and smooth harvesting of green onions.

[0034] The second blade 32 assists the first blade 31 to improve the soil loosening process, ensure that the green onion harvesting process is not stuck due to local soil loosening, and optimize the overall green onion pulling environment.

[0035] In the ingenious design of the green onion harvesting equipment, the rotating blades at both ends of the rotating shaft 14 each have their own functions, and the second blade 32 has a unique and indispensable position. In terms of the setting relationship, the second blade 32 and the first blade 31 are separated at both ends of the rotating shaft 14, and this layout forms a complementary situation. Multiple first blades 31 are arranged at intervals along the axis of the rotating shaft 14, and the number far exceeds the second blades 32. A specific interval is left between the two, and the lever 33 is placed at this interval position, while the second blade 32 firmly occupies the other end of the rotating shaft 14.

[0036] This setting of quantity and position is not random, it precisely meets the actual needs of green onion harvesting. Since the first blades 31 are numerous, they are responsible for cutting into the soil around the roots of green onions over a large area and at a high frequency. Their soil loosening operation is as efficient as a storm, but because of this, it is difficult to do it without omission. At this time, the smaller number of second blades 32 highlights its value. When the drive wheel 12 drives the transmission system and causes the rotating shaft 14 to rotate, the second blade 32 follows the rotation, and its rotation trajectory just matches the working area of ​​the first blade 31.

[0037] When the first blade 31 rotates at high speed and hits the soil vigorously, the soil in most areas of the root of the green onion begins to loosen and the adhesion is reduced, but some gaps will still remain. If the soil in these areas is not treated, the green onions may get stuck when they are pulled out later. The second blade 32 can just fill the gaps left by the first blade 31 when loosening the soil, and turn over the missed soil blocks by the force generated by its own rotation.

[0038] The occurrence of soil loosening dead corners is completely eliminated, and the roots of the green onions can be effectively loosened in all directions. This is of great significance for the continuity of the subsequent pulling action. Imagine that if the soil at the roots is only partially loosened, the onions will inevitably be stubbornly resisted by the unloosened soil during pulling, resulting in jamming or even damage to the green onions. The presence of the second blade 32 kills this hidden danger in the cradle.

[0039] Moreover, the second blade 32 assists the first blade 31 to stabilize the entire soil loosening process. In the complex process of green onion harvesting, soil loosening is the starting point. If this link is partially loosened, it is difficult to advance smoothly.

[0040] In addition, the lever 33 perpendicular to the axis of the rotating shaft 14 and the hanging rod 34 on the other side of the rotating shaft 14, together with the second blade 32, form a fully functional operating system. The lever 33 may be able to assist in regulating the flow direction of the soil during operation to prevent the disordered accumulation of soil after loosening from affecting the operation of the second blade 32. The hanging rod 34 may also play a role in material drainage. The three complement each other, allowing the second blade 32 to more efficiently exert its perfect soil loosening, making the green onion harvesting operation efficient and stable. In summary, the second blade 32 achieves excellent technical effects by virtue of its exquisite setting relationship.

[0041] The setting direction of the lever 33 is perpendicular to the axial direction of the rotating shaft 14 . A material hanging rod 34 is set on the rotating shaft 14 . The material hanging rod 34 and the lever 33 are respectively located on both sides of the rotating shaft 14 .

[0042] The lever 33 is arranged between the first blade 31 and the second blade 32 perpendicular to the axis direction of the rotating shaft 14. When the blades have finished loosening the soil, as the rotating shaft 14 rotates, the lever 33 accurately lifts the green onion plants from the loosened soil and pushes them to the predetermined collection direction, thereby reducing the disorderly scattering of green onions and avoiding the subsequent manual large-scale collection, thus effectively improving the continuity and overall efficiency of the harvest.

[0043] The lever 33 takes over the step of loosening the soil with blades, realizing an orderly transition of the green onions from underground to the collection process, saving the time and labor cost of manually arranging the green onions, and enhancing the automation degree of the harvesting process.

[0044] A plurality of shifting rods 33 are arranged at intervals along the axial direction of the rotating shaft 14 , and a plurality of material hanging rods 34 are arranged at intervals along the axial direction of the rotating shaft 14 . The interval size between adjacent shifting rods 33 is greater than the interval size between adjacent material hanging rods 34 .

[0045] The hanging rod 34 and the lever 33 are separated on both sides of the rotating shaft 14 and arranged at intervals along the axis direction, and the intervals between adjacent levers 33 are larger than the intervals between adjacent hanging rods 34. During the harvesting process, the hanging rod 34 can hang on some stems and leaves of the green onion, assisting the lever 33 to stabilize the position of the green onion, preventing the green onion from falling due to shaking during the lifting and transportation, ensuring the stability of the green onion transportation, and allowing the green onion to be more accurately transported to the collection area.

[0046] The hanging rod provides additional support and positioning for the green onion conveying process, and cooperates with the lever 33 to solve the problem that the green onions are easy to fall during conveying, thereby improving the accuracy and stability of green onion conveying when the harvesting device is running.

[0047] The arrangement of the first blade 31, the second blade 32 and the lever 33 significantly improves the harvesting efficiency. The plurality of first blades 31 spaced apart along the axis of the rotating shaft 14 are greater in number than the second blades 32. When the rotating shaft 14 rotates, the blades 31 cut into the soil over a large area and at a high frequency. With the advantage of quantity, the soil around the roots of the green onions can be quickly loosened, reducing the resistance to the green onions being pulled up, making it easier for the green onions to be separated from the soil environment.

[0048] The second blade 32 cooperates with the first blade 31 to work together from different positions to fill the "blind spot" of loosening the soil, so that the soil around the roots of the green onions can be turned over more comprehensively and evenly, creating more favorable basic conditions for the subsequent pulling out of the green onions.

[0049] The first blade 31 and the second blade 32 are respectively installed at both ends of the rotating shaft 14. Multiple first blades 31 are welded at equal intervals (for example, 20 cm) along the axis direction of the rotating shaft 14. The number is set to 8. The number of second blades 32 is 4, which are symmetrically distributed at the other end of the rotating shaft 14. At a suitable position between the first blade 31 and the second blade 32, a lever 33 is welded perpendicular to the axis direction of the rotating shaft 14. The lever 33 is of moderate length, sufficient to lift the green onion, and adjacent levers 33 are spaced 40 cm apart. On the other side of the rotating shaft 14, a corresponding hanging rod 34 is installed, and adjacent hanging rods 34 are spaced 30 cm apart. The hanging rod 34 uses a slightly curved metal rod to facilitate hanging the stems and leaves of the green onion.

[0050] The lever 33 is located at a key position between the first blade 31 and the second blade 32. When the green onion is initially loosened by the blade, the lever 33 takes over. It can accurately pull the green onion plants out of the loosened soil, and push the green onions in an orderly manner to the predetermined collection direction with appropriate spacing and angle settings, so as to prevent the green onions from being scattered randomly and reduce the time loss of subsequent manual secondary sorting. The three cooperate with each other, from loosening the soil to pulling up and then to sorting, all in one go, reducing the jams and stagnation in the harvesting process, greatly shortening the harvesting time of a single green onion plant, and improving the overall efficiency of green onion harvesting.

[0051] When the shaft 14 rotates rapidly under the drive wheel 12, the lever 33 rotates at high speed. Its shape perpendicular to the shaft gives it an excellent cutting angle. It can break up and disperse the large pieces of soil loosened and lifted by the first blade 31, making the soil particles more fine and uniform, creating good conditions for the subsequent second blade 32 to fill the gap more finely. The compacted soil blocks turned over by the first blade 31 are hit and poked by the lever 33, turning into loose small soil particles, which are easier to be processed by the second blade 32, making the soil loosening work at the roots of the green onions progressive and more perfect.

[0052] The lever 33 also plays a role in optimizing the flow direction of the soil. When the green onions are harvested, the loosened soil needs to be quickly discharged to make room for the green onions to be pulled out. The centrifugal force generated by the rotation of the lever 33 can guide the loosened soil to move in a specific direction, preventing the soil from piling up disorderly around the shaft and obstructing subsequent blade operations. Moreover, it is separated from the hanging rod 34 on both sides of the shaft. This symmetrical layout maintains the dynamic balance of the shaft during operation. The hanging rod 34 may be responsible for guiding crop residues and debris, while the lever 33 focuses on soil regulation. The two cooperate with each other to ensure that the entire shaft system operates stably, and there will be no shaking, jamming, or other conditions that affect the operating efficiency due to uneven force on one side and material accumulation. In addition, the lever 33 indirectly helps the continuity of pulling out the green onions.

[0053] On the key component of the rotating shaft 14 of the green onion harvesting device, the hanging rod 34 is cleverly matched with the lever 33 and the rotating blades, which have made great contributions to the smooth development of the entire harvesting process. The hanging rod 34 and the lever 33 are separated on both sides of the rotating shaft 14. Such a layout is first aimed at maintaining the dynamic balance of the rotating shaft during operation. When the driving wheel 12 drives the rotating shaft 14 to rotate at high speed through the transmission system, the centrifugal force generated by the rotation of each component must be evenly distributed, otherwise the rotating shaft is prone to shaking and offset, affecting the stability and service life of the equipment. The hanging rod 34 "balances" the force brought by the lever 33 and the rotating blades on one side to ensure that the rotating shaft 14 always runs smoothly, laying the foundation for continuous operation.

[0054] The hanging rod 34 avoids the core area where the first blade 31 and the second blade 32 operate, that is, the main loosening range of the soil around the roots of the green onions. This avoidance allows the blades to loosen the soil without interference, and can focus on reducing the adhesion between the roots of the green onions and the soil. And it is located next to the rotating shaft 14, cleverly utilizing the idle space around it, without occupying the green onion pulling route, so that the green onions can be pulled straight up without any obstacles after being loosened.

[0055] The hanging rod 34 also plays an auxiliary role in soil drainage. Although it does not cut into the soil in a large area like the first blade 31, nor does it finely control the soil particles like the lever 33, its rotation will drive the surrounding airflow. After the soil at the root of the green onion is loosened into fragments, this weak airflow helps the soil particles to spread around, further freeing up a clean and open pulling space for the roots of the green onion, and coordinating with the lever 33 to organize the soil in a more orderly manner, indirectly ensuring the seamless connection between soil loosening and green onion pulling, so that the green onion harvesting process is linked together and efficiently promoted, optimizing the overall harvesting effect from the details.

[0056] The power source is started, and the driving wheel 12 starts to rotate, driving the first transmission wheel 21, the second transmission wheel 22, and the rotating wheel 13 in turn, causing the rotating shaft 14 to rotate at a high speed. The first blades 31 first cut into the soil around the roots of the green onions, and with the advantage of number, quickly turn over a large area of ​​the soil, and then the second blades 32 loosen the soil. The two cooperate to effectively loosen the soil within a 360° range around the roots of the green onions, reducing the resistance of the green onion roots.

[0057] Lifting and conveying: As the rotating shaft 14 continues to rotate, the lever 33 begins to work, and the lever 33 accurately lifts the green onion plants in the loosened soil and pushes them in a predetermined direction. During this process, the hanging rod 34 hangs on part of the stems and leaves of the green onion to help stabilize the posture of the green onion and prevent the green onion from deviating from the conveying route due to shaking, and the green onion is sent to the collection area in an orderly manner.

[0058] Continuous operation: The device moves in a straight line along the ridges of the onion field, continuously repeating the above-mentioned loosening, lifting and conveying processes to achieve efficient and continuous harvesting of onions. Compared with traditional manual harvesting methods, it greatly shortens the harvesting time of a single acre of onions, reduces labor costs, and improves harvesting efficiency and quality.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
