Description

Technical Field

[0001] This invention belongs to the field of harvesting machine technology, specifically relating to a lever-type mulberry leaf harvesting device. Background Technology

[0002] In the agricultural sector, mulberry leaves are a key raw material for silk production, and the efficiency and quality of their harvesting directly affect the stability and development of the silk industry. However, current mulberry leaf harvesting mainly relies on traditional manual harvesting methods. This method is not only labor-intensive and inefficient, but also faces a serious problem of a lack of successors due to the aging rural population and the migration of young laborers to cities, severely restricting the sustainable development of the mulberry leaf industry.

[0003] Currently, while some attempts at mulberry leaf harvesting machinery exist in the market, these machines are often complex in structure and inconvenient to operate due to the specific technical requirements of mulberry leaf harvesting (such as the high requirements for the integrity and cleanliness of the leaves) and the complex working environment (such as densely packed mulberry trees and intertwined branches). Furthermore, their harvesting results are difficult to match those achieved by manual harvesting, and therefore, they have not gained widespread application and acceptance. The market currently lacks a mulberry leaf harvesting machine that is both efficient and practical to meet the needs of modern agriculture for mulberry leaf harvesting operations. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a lever-type mulberry leaf picking device, which solves the problems of low efficiency and poor picking results caused by the reliance on manual picking in existing mulberry leaf picking machines.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A lever-type mulberry leaf harvesting device is provided, including a collection box with a frame inside. A moving component is mounted on the frame and connected to a lever component. The lever component is connected to a harvesting component. The lever component includes a pulley motor, the output end of which is connected to one end of a pulley coupling. The other end of the pulley coupling is connected to a pulley. The pulley is connected to a fixed wheel via a fixed rope. The fixed wheel is connected to the harvesting component. The harvesting component, lever component, and moving component are all electrically connected to a control system.

[0007] The beneficial effects of adopting the above technical solution are as follows: The lever-type mulberry leaf picking device uses a combination of electric drive and mechanical lever to realize the automated and continuous picking and collection of mulberry leaves, which greatly reduces the intensity of manual labor and time costs. Moreover, it has a compact structure and coordinated movements, and can operate stably in complex mulberry planting environments, avoiding physical damage to mulberry branches and leaves. At the same time, the pure electric control eliminates exhaust pollution caused by fuel engines. The frame provides a stable mounting platform for the mobile components, ensuring accurate and stable operation of the harvesting device and guaranteeing the overall stability and reliability of the harvesting device. The mobile components adopt a one-dimensional double-track parallel structure, achieving precise positioning and smooth movement of the harvesting device in the horizontal direction. This allows the harvesting components to quickly and stably approach the target mulberry branches, improving harvesting accuracy and efficiency. Through the coordinated action of the pulley motor, pulleys, fixed ropes, and fixed wheels, the rotational motion is converted into lever swing, driving the harvesting components to complete the harvesting action. The transmission efficiency is high, and the harvesting angle is controllable, significantly reducing impact and vibration during the harvesting process and protecting the mulberry branches from damage. The harvesting components can be opened and closed under the control of the control system to clamp and cut the mulberry leaves, ensuring cutting efficiency while reducing mechanical damage to the mulberry branches. After harvesting, the mulberry leaves are collected in a collection box, achieving immediate collection and centralized processing of the harvested mulberry leaves, avoiding scattering and secondary pollution, improving the efficiency of integrated harvesting operations, and facilitating subsequent transportation and processing.

[0008] Furthermore, the harvesting assembly includes a blade, which is disposed on the inner side of a first blade fixing plate and a second blade fixing plate. The first blade fixing plate and the second blade fixing plate are hinged together and slidably connected to a fixed platform. The end of the first blade fixing plate and the second blade fixing plate away from the blade is connected to one end of an electric push rod, and the other end of the electric push rod is disposed on one side of an electric push rod fixing plate.

[0009] The beneficial effects of adopting the above technical solution are as follows: the harvesting component can achieve stable opening and closing and precise positioning of the blades through the hinged connection between the first blade fixing plate and the second blade fixing plate, and the sliding connection between the first blade fixing plate and the second blade fixing plate and the fixed platform. When the electric push rod is started, it can drive the first blade fixing plate and the second blade fixing plate to slide on the fixed platform, and use their hinged connection to achieve stable opening and closing of the blades, thereby completing clamping and cutting simultaneously. This not only improves the efficiency and reliability of mulberry leaf harvesting, but also reduces damage to mulberry branches, which is conducive to ensuring the integrity of mulberry leaves and the quality of harvesting.

[0010] Furthermore, a first slide groove and a second slide groove are provided on the fixed platform. The second slide groove is located above the first slide groove. The first slide groove is arc-shaped, and the second slide groove is straight. The end of the first tool fixing plate away from the tool is connected to one end of the first opening and closing slide shaft. The end of the second tool fixing plate away from the tool is connected to one end of the second opening and closing slide shaft. Both the first and second opening and closing slide shafts are located in the first slide groove. The other end of the first opening and closing slide shaft is connected to one end of the first connecting rod. The other end of the second opening and closing slide shaft is connected to one end of the second connecting rod. The other ends of both the first and second connecting rods are connected to one end of the third connecting rod. One end of the third connecting rod is located in the second slide groove, and the other end of the third connecting rod is connected to one end of the electric push rod.

[0011] The beneficial effects of adopting the above technical solution are as follows: by using the arc-shaped first slide groove and the straight second slide groove in tandem, the linear motion of the electric push rod can be transformed into the composite motion of the first opening and closing slide shaft and the second opening and closing slide shaft, thereby controlling the opening and closing of the first tool fixing plate and the second tool fixing plate, effectively reducing friction and jamming during the movement, ensuring the smoothness and synchronization of the tool clamping action, thus significantly improving the reliability and efficiency of harvesting, and reducing the impact and mechanical damage to mulberry branches.

[0012] Furthermore, the outer surfaces of the first and second tool fixing plates are provided with harvesting and collection protective covers.

[0013] The beneficial effects of adopting the above technical solution are as follows: the picking protective cover is set on the outer side of the first cutter fixing plate and the second cutter fixing plate, which can effectively cover the mulberry leaves when the cutter performs the cutting action, prevent the mulberry branches from falling off, and ensure that the cut mulberry leaves can be smoothly guided and fall into the collection box, thereby reducing leaf loss and pollution during the harvesting process and improving the integrity of mulberry leaf picking.

[0014] Furthermore, a first lever frame and a second lever frame are correspondingly provided at the end of the fixed platform away from the tool. The first lever frame and the second lever frame are connected to the electric push rod fixing plate through the first fixed base plate, and the first lever frame and the second lever frame are connected to the fixed wheel through the second fixed base plate.

[0015] The beneficial effects of adopting the above technical solution are as follows: the first lever frame and the second lever frame are connected to the electric push rod fixing plate and the fixed wheel respectively by the first fixed plate and the second fixed plate, forming a stable and reliable lever transmission fulcrum structure, which improves the structural stability and force uniformity of the harvesting component in reciprocating motion, ensures the efficient and accurate transmission of power from the fixed wheel to the harvesting blade, and reduces vibration and deformation during the movement, thus extending the service life of the harvesting device.

[0016] Furthermore, the cutting edge of the knife is arc-shaped.

[0017] The beneficial effects of adopting the above technical solution are as follows: the rounded blade can better fit the circular contour of the mulberry branch, and achieve smooth and labor-saving sliding shearing when cutting the petiole of the mulberry leaf, rather than vertical cutting, thereby reducing the tearing and damage to the bark of the mulberry branch, which is conducive to the wound healing and subsequent growth of the mulberry tree. At the same time, it ensures the neatness of the cut surface, improves the success rate of harvesting and the quality of mulberry leaf harvesting.

[0018] Furthermore, the moving component includes a slide rail motor, the output end of which is connected to a connecting shaft. A first slide rail and a second slide rail are mounted on the connecting shaft. Both the first and second slide rails are mounted on the frame via slide rail fixing plates. A connecting coupling is provided between the first and second slide rails. The first slide rail is slidably connected to the first slider, and the second slide rail is slidably connected to the second slider. The first and second sliders are connected via a slider connecting plate. A first fixed base and a second fixed base are provided at the lower end of the slider connecting plate. A lever rotating shaft is provided between the first and second fixed bases, and the lever rotating shaft is rotatably connected to the first lever frame and the second lever frame.

[0019] The beneficial effects of adopting the above technical solution are as follows: the moving component drives the connecting shaft through the slide rail motor to move the first slide rail and the second slide rail synchronously. The slider connecting plate ensures the consistency between the first slide rail and the second slider, thereby realizing the stable and smooth movement of the harvesting component in the horizontal direction, ensuring the accuracy of harvesting positioning and the stability of the harvesting device, thereby improving the efficiency and reliability of harvesting operations.

[0020] Furthermore, a third fixed base plate and a fourth fixed base plate are provided at the lower end of the slider connecting plate. The third fixed base plate and the fourth fixed base plate are respectively provided on one side of the first fixed base plate and the second fixed base plate. A fifth fixed base plate is provided at the end of the third fixed base plate and the fourth fixed base plate away from the slider connecting plate. The fifth fixed base plate is connected to the pulley through the third fixed base. A pulley motor is provided on the outer side of the third fixed base plate.

[0021] The beneficial effects of adopting the above technical solution are as follows: through the hierarchical connection of the third, fourth and fifth fixed base plates, the pulley motor and pulley can be stably integrated under the moving component, forming a compact and efficient power transmission path. This not only optimizes the overall spatial layout and avoids external interference, but also improves the stability and synchronization of the lever component in the process of tightening the wire rope, thereby ensuring the accuracy and reliability of the angle adjustment of the harvesting component and improving the coordination and work efficiency of the harvesting cycle.

[0022] Furthermore, a steel wire rope is wound around the pulley, and one end of the steel wire rope is connected to the fixed wheel.

[0023] The beneficial effects of adopting the above technical solution are as follows: by winding a steel wire rope around a pulley and connecting it to a fixed wheel, the rotational motion of the pulley motor is converted into the linear winding and unwinding of the steel wire rope, thereby controlling the flipping angle and picking force of the harvesting component. Moreover, this transmission method has a simple structure, sensitive response, and high power transmission efficiency, ensuring the stability and repeatability of the picking action, while reducing the instantaneous impact on the load of the pulley motor and extending the service life of the harvesting device.

[0024] In summary, the lever-type mulberry leaf picking device provided by this invention has the following beneficial effects:

[0025] (1) The picking device achieves automated and continuous mulberry leaf picking through the coordinated use of electric drive and mechanical levers, changing the traditional manual picking mode. Its overall structure is compact and its movements are coordinated, enabling it to operate stably in complex mulberry planting environments. This not only significantly reduces labor intensity and time costs, but also effectively avoids physical damage to mulberry branches and leaves. At the same time, the pure electric drive avoids exhaust pollution from fuel engines, ensuring the cleanliness of mulberry leaves. It is particularly suitable for the high standards of feed required for silkworm breeding and significantly improves operational efficiency.

[0026] (2) The moving component in the harvesting device adopts a one-dimensional double-track parallel structure. It is driven by a slide rail motor and realizes the synchronous movement of the first slide rail and the second slide rail through the connecting shaft and the connecting coupling. This ensures the accurate, smooth and stable movement of the harvesting component in the horizontal direction, and enables the device to quickly and accurately position itself to the mulberry branch to be harvested, thereby improving the positioning accuracy and work efficiency of the harvesting, while ensuring the overall stability and reliability of the harvesting device in reciprocating motion.

[0027] (3) The lever assembly in the harvesting device forms a transmission structure through the pulley motor, pulley and fixed wheel, which can convert the rotational motion of the pulley motor into a linear release mode, thereby controlling the flipping angle and harvesting force of the harvesting assembly. Moreover, the lever transmission mode has a simple structure, sensitive response and high power transmission efficiency, which not only ensures the stability and repeatability of the harvesting action, but also significantly reduces the instantaneous impact on the pulley motor, extends the service life of the harvesting device, and realizes precise control of the harvesting process.

[0028] (4) The harvesting component in the harvesting device achieves stable opening and closing and precise cutting of the blade through the coordinated use of the hinged first blade fixing plate and second blade fixing plate, first slide groove, second slide groove and electric push rod. The blade edge is arc-shaped, which can better fit the contour of the mulberry branch for sliding shearing, reducing tearing damage to the mulberry branch. The harvesting and collection protective cover can effectively prevent mulberry leaves from flying away, ensuring that the mulberry leaves can fall into the collection box intact. This ensures the high efficiency of cutting, protects the growth capacity of the mulberry tree and the harvesting quality of the mulberry leaves, and has better operational adaptability and reliability.

[0037] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0038] like Figures 1 to 7 As shown, the lever-type mulberry leaf harvesting device provided by the present invention includes a collection box 1, inside which a frame 11 is installed. The frame 11 is bolted to the collection box 1. A moving component 2 is installed on the frame 11, which is connected to a harvesting component 4. The harvesting component 4 is connected to a lever component 3. The moving component 2, the harvesting component 4, and the lever component 3 are all connected to a control system. This lever-type mulberry leaf harvesting device, through the coordinated operation of the moving component 2, the harvesting component 4, and the lever component 3, and under the unified control of the control system, realizes fully automated operation from positioning, clamping, cutting to collection. It significantly improves harvesting efficiency and consistency, reduces reliance on manual labor and labor intensity. At the same time, electric drive avoids pollution and ensures the cleanliness of mulberry leaves. Moreover, its overall structure is compact and its movements are coordinated, enabling stable operation in complex mulberry planting environments. It is suitable for efficient and damage-free harvesting in complex mulberry orchard environments.

[0039] like Figure 3 and Figure 4 As shown, the moving component 2 includes a slide rail motor 21. The output end of the slide rail motor 21 is connected to a connecting shaft 22. A first slide rail 23 and a second slide rail 24 are provided on the connecting shaft 22. The first slide rail 23 and the second slide rail 24 are both mounted on the frame 11 via a slide rail fixing plate 25. A connecting coupling 26 is provided between the first slide rail 23 and the second slide rail 24. The first slide rail 23 is slidably connected to the first slider 27, and the second slide rail 24 is slidably connected to the second slider 28. The first slider 27 and the second slider 28 are connected via a slider connecting plate 29. A first fixed base 210 and a second fixed base 211 are provided at the lower end of the slider connecting plate 29. A lever rotating shaft 45 is provided between the first fixed base 210 and the second fixed base 211. The lever rotating shaft 45 is rotatably connected to the first lever frame 3511 and the second lever frame 3611. The moving component 2 drives the connecting shaft 22 through the slide rail motor 21 to move the first slide rail 23 and the second slide rail 24 synchronously. The slider connecting plate 29 ensures the consistency between the first slide rail 23 and the second slider 28, thereby realizing the stable and smooth movement of the harvesting component 4 in the horizontal direction, ensuring the accuracy of harvesting positioning and the stability of the harvesting device, thus improving the efficiency and reliability of the harvesting operation.

[0040] like Figure 4 and Figure 5As shown, a third fixed base plate 212 and a fourth fixed base plate 213 are provided at the lower end of the slider connecting plate 29. The third fixed base plate 212 and the fourth fixed base plate 213 are respectively provided on one side of the first fixed base plate 37 and the second fixed base plate 38. A fifth fixed base plate 214 is provided at the end of the third fixed base plate 212 and the fourth fixed base plate 213 away from the slider connecting plate 29. The fifth fixed base plate 214 is connected to the lever assembly 3 through the third fixed base 215. Through the hierarchical connection of the third fixed base plate 212, the fourth fixed base plate 213 and the fifth fixed base plate 214, the lever assembly 3 can be stably integrated under the moving assembly 2, forming a compact and efficient power transmission path. This not only optimizes the overall spatial layout and avoids external interference, but also improves the stability and synchronization of the lever assembly 3 during the tightening of the wire rope, thereby ensuring the accuracy and reliability of the angle adjustment of the harvesting assembly 4 and improving the coordination and work efficiency of the harvesting cycle.

[0041] like Figure 5 and Figure 6 As shown, the lever assembly includes a pulley motor 31, which is mounted on the outer side of the third fixed base plate 212. The output end of the pulley motor 31 is connected to one end of a pulley coupling 32, and the other end of the pulley coupling 32 is connected to a pulley 33. The pulley 33 is connected to the fifth fixed base plate 214 via a third fixed base 215, and a steel wire rope is wound around the pulley 33. One end of the steel wire rope is connected to a fixed wheel 34, which is connected to the harvesting assembly 4. The lever assembly 3 is driven by the pulley motor 31, which in turn drives the pulley 33 to rotate via the pulley coupling 32. By winding and unwinding the steel wire rope wound around the pulley 33, the fixed wheel 34 and the harvesting assembly 4 are pulled, thus converting the rotational motion of the pulley motor 31 into precise and controllable linear traction. This transmission method has a simple and compact structure, high power transmission efficiency, and sensitive response. It can accurately control the flipping angle and harvesting force of the harvesting assembly 4, ensuring the stability and consistency of the harvesting action, while reducing the impact on the motor and extending the service life of the harvesting device.

[0042] like Figure 4 , Figure 6 and Figure 7As shown, the harvesting assembly 4 includes a blade 41 with an arc-shaped cutting edge. The blade 41 is disposed on the inner side of the first blade fixing plate 42 and the second blade fixing plate 43. The first blade fixing plate 42 and the second blade fixing plate 43 are hinged together and slidably connected to the fixed platform 44. The end of the first blade fixing plate 42 and the second blade fixing plate 43 away from the blade 41 is connected to one end of the electric push rod 47. The other end of the electric push rod 47 is disposed on one side of the electric push rod fixing plate 46. The harvesting assembly 4 achieves stable opening and closing and precise positioning of the blade 41 through the hinged connection between the first blade fixing plate 42 and the second blade fixing plate 43, and the sliding connection between the first blade fixing plate 42 and the second blade fixing plate 43 and the fixed platform 44. When the electric push rod 47 is started, it can drive the first blade fixing plate 42 and the second blade fixing plate 43 to slide on the fixed platform 44, and use their hinged connection to achieve stable opening and closing of the blade 41, thereby completing clamping and cutting simultaneously. This not only improves the efficiency and reliability of mulberry leaf harvesting, but also reduces damage to mulberry branches, which helps to ensure the integrity of mulberry leaves and the quality of harvesting.

[0043] like Figure 4 and Figure 6 As shown, the fixed platform 44 is provided with a first slide groove 48 and a second slide groove 49. The second slide groove 49 is located above the first slide groove 48. The first slide groove 48 is arc-shaped, and the second slide groove 49 is straight. The end of the first tool fixing plate 42 away from the tool 41 is connected to one end of the first opening and closing slide shaft 410. The end of the second tool fixing plate 43 away from the tool 41 is connected to one end of the second opening and closing slide shaft 411. The first opening and closing slide shaft 410 and the second opening and closing slide shaft 411 are both located in the first slide groove 48. The other end of the first opening and closing slide shaft 410 is connected to one end of the first connecting rod 412. The other end of the second opening and closing slide shaft 411 is connected to one end of the second connecting rod 413. The other ends of the first connecting rod 412 and the second connecting rod 413 are both connected to one end of the third connecting rod 414. One end of the third connecting rod 414 is located in the second slide groove 49. The other end of the third connecting rod 414 is connected to one end of the electric push rod 47. By using the arc-shaped first slide groove 48 and the straight second slide groove 49 in coordination, the linear motion of the electric push rod 47 can be converted into the composite motion of the first opening and closing slide shaft 410 and the second opening and closing slide shaft 411, thereby controlling the opening and closing of the first tool fixing plate 42 and the second tool fixing plate 43. This effectively reduces friction and jamming during the movement, ensuring the smooth and synchronous clamping action of the tool 41, thus significantly improving the reliability and efficiency of harvesting and reducing the impact and mechanical damage to the mulberry branches.

[0044] like Figure 4 and Figure 6As shown, the outer surfaces of the first cutter fixing plate 42 and the second cutter fixing plate 43 are provided with harvesting and collection protective covers 415. The harvesting protective covers are provided on the outer surfaces of the first cutter fixing plate 42 and the second cutter fixing plate 43. They can effectively cover the mulberry leaves when the cutter 41 performs the cutting action, prevent the mulberry branches from falling off, and ensure that the cut mulberry leaves can be smoothly guided and fall into the collection box 1, thereby reducing leaf loss and contamination during the harvesting process and improving the integrity of mulberry leaf harvesting.

[0045] like Figure 5 As shown, a first lever frame 35 and a second lever frame 36 are correspondingly provided at the end of the fixed platform 44 away from the blade 41. The first lever frame 35 and the second lever frame 36 are connected to the electric push rod fixing plate 46 through the first fixed base plate 37, and the first lever frame 35 and the second lever frame 36 are connected to the fixed wheel 34 through the second fixed base plate 38. By connecting the first lever frame 35 and the second lever frame 36 to the electric push rod fixing plate 46 and the fixed wheel 34 respectively through the first fixed base plate 37 and the second fixed base plate 38, a stable and reliable lever transmission fulcrum structure is formed. This improves the structural stability and force uniformity of the harvesting component 4 in reciprocating motion, ensures the efficient and accurate transmission of power from the fixed wheel 34 to the harvesting blade 41, and reduces vibration and deformation during the movement, thus extending the service life of the harvesting device.

[0046] The working principle of the lever-type mulberry leaf picking device in this invention is as follows: After the picking device is powered on, the control system controls each structure individually. The slide rail motor 21 drives the connecting shaft 22 to move the first slide rail 23 and the second slide rail 24 synchronously, causing the first slider 27 and the second slider 28 to move along the first slide rail 23 and the second slide rail 24 respectively, positioning the harvesting component 4 to the position of the mulberry branch to be picked. After reaching the picking position, the electric push rod 47 extends, pushing the hinged first cutter fixing plate 42 and the second cutter fixing plate 43 to... The blade 41 slides within the first groove 48 and the second groove 49 on the fixed platform 44, closing the blade 41 and clamping the mulberry leaf petiole. Then, the pulley motor 31 starts, tightening the steel wire rope through the pulley 33, pulling the fixed wheel 34 and the harvesting assembly 4 to rotate upward around the lever axis 45, completing the cutting action. The cut mulberry leaves fall into the collection box 1 under the guidance of the harvesting and collecting protective cover 415, avoiding the scattering and contamination of mulberry leaves. After harvesting is completed, the electric push rod 47 retracts, the harvesting device resets, and the next cycle begins.

[0047] In summary, the lever-type mulberry leaf picking device provided by this invention achieves automated and continuous mulberry leaf picking through the coordinated use of electric drive and mechanical levers, changing the outdated mode of relying on manual picking. Its compact structure and coordinated movements allow it to operate stably in complex mulberry planting environments, significantly reducing labor intensity and time costs while effectively preventing physical damage to mulberry branches and leaves. Furthermore, the pure electric drive avoids exhaust pollution from fuel-powered engines, ensuring the cleanliness of the mulberry leaves. This makes it particularly suitable for the high standards of feed required in silkworm farming and significantly improves operational efficiency.
