Description

Technical Field

[0001] This invention relates to the field of machinery for packaging objects or materials, belonging to the field of agricultural machinery, and particularly to an automated mulberry leaf collection and baling machine. Background Technology

[0002] Sericulture, as a traditional and advantageous agricultural industry in my country, is a crucial channel for silkworm farmers to increase their income and achieve prosperity. Currently, the total area of ​​mulberry orchards in China is approximately 12 million mu (about 800,000 hectares). The main stages of mulberry planting and silkworm rearing are labor-intensive, and with the large-scale migration of rural labor, the age structure of silkworm farmers is aging significantly. At present, mulberry planting and silkworm rearing are still mainly done manually, resulting in high labor intensity and low labor productivity. The overall mechanization rate (mechanization level) of sericulture production nationwide is less than 5%, which is incompatible with the development direction of modern agriculture towards large-scale, standardized, and mechanized production, affecting the sustainable, stable, and healthy development of sericulture production. Therefore, this invention is necessary to address the current difficulties in large-scale mulberry harvesting, the need to improve the mechanization rate of mulberry leaf harvesting, the continuous rise in labor costs, and the lack of well-matched automated mulberry leaf collection and baling machines for mechanized mulberry leaf picking.

[0003] The invention patent published under CN116210455A discloses a mulberry leaf picking device. This picking mechanism can pick and collect leaves from a single mulberry tree, but it cannot automate the collection, bagging, and packaging processes in one integrated manner. Some manual labor is still required, which affects the overall harvesting efficiency of mulberry leaves in the mulberry orchard.

[0004] The invention patent with publication number CN116477127A discloses an automatic mulberry leaf collection and packaging device. This device can collect and package mulberry leaves, but it cannot automatically pick up the leaves from the harvesting mechanism, nor can it achieve full automation, still requiring some manual intervention. The biggest difference between this invention and publication number CN116477127A is that this invention can automatically pick up mulberry leaves in conjunction with the harvesting mechanism. Simultaneously, through pressure sensors, the device autonomously completes the processes of picking up mulberry leaves, transferring mulberry leaves, packaging mulberry leaf collection bags, and discharging mulberry leaf collection bags, and then starts a new round of work, all without the need for manual intervention. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing mulberry orchard harvesting machines lack a well-matched automated mulberry leaf collection and baling machine, which affects the efficiency and scale of mulberry orchard operations and increases labor costs due to the inefficient collection and baling of harvested mulberry leaves. This invention discloses an automated mulberry leaf collection and baling machine.

[0006] To address the aforementioned issues, this example presents an automated mulberry leaf collection and baling machine, characterized by comprising six main components: a fixed frame, a transfer device, a material guiding device, a bag changing device, a bag opening device, and a base plate.

[0007] Furthermore, the fixed frame is fixed above the base plate and specifically includes a transfer device frame, a material guiding device frame, a bag changing device frame, and a bag opening device frame.

[0008] Furthermore, the transfer device specifically includes a telescopic frame, a leaf-receiving canopy, a connecting rod, and an electric push rod. The telescopic frames are installed in pairs on the side of the transfer device frame, the leaf-receiving canopy is set above the telescopic frames, and a connecting rod is set at the front and rear of the telescopic frames respectively.

[0009] Preferably, an electric push rod is installed below the telescopic frame. When the electric push rod is pushed upward, the telescopic frame extends, and the extension of the telescopic frame drives the leaf-collecting canopy to extend to the right; when the electric push rod is retracted downward, the telescopic frame retracts, and the retraction frame drives the leaf-collecting canopy to retract to the left. When the leaf-collecting canopy extends, it receives the harvested mulberry leaves; when the leaf-collecting canopy retracts, it transports the mulberry leaves to the feeding device.

[0010] Furthermore, the material guiding device specifically includes a housing and an anti-clogging mechanism. The anti-clogging mechanism specifically includes a bearing, a rotating blade, a transmission shaft, and a motor. The housing is installed in the middle of the material guiding device frame, with both sides of the housing fixed to the sides of the material guiding device frame, and the rear side of the housing fixed to the rear side of the material guiding device frame.

[0011] Preferably, bearings are fixed in pairs on both sides of the housing. A motor is installed on the left side of the housing, and bearings are installed on both sides of the drive shaft. The motor drives the drive shaft to rotate, which in turn drives the rotating blades to rotate. The rotating blades transport the mulberry leaves stuck on the inclined surface of the housing to the mulberry leaf collection bag, thus preventing blockage. After the transfer device transfers the mulberry leaves to the housing, the rotating blades transport the mulberry leaves to the mulberry leaf collection bag, while preventing the mulberry leaves from clogging in the housing.

[0012] Furthermore, the bag-changing device specifically includes a mulberry leaf collection bag, a chain and sprocket mechanism, a bearing, a drive shaft, a coupling, and a motor. The bearing specifically includes a front bearing and a rear bearing. The chain and sprocket mechanism specifically includes a driven sprocket, a drive chain, a fixing hole, a driving sprocket, a hook, and a bag-carrying hole. The drive shaft specifically includes a rear drive shaft and a front drive shaft. The mulberry leaf collection bag specifically includes a main bag body, an electromagnet, a hook hole, and Velcro.

[0013] Preferably, the second motor is fixed to the upper left of the bag-changing device frame. Rear bearings are fixed in pairs to the upper rear side of the bag-changing device frame, with the left rear bearing connected to the second drive shaft, which is installed in the rear bearing and connected to the second motor via a coupling. A pair of drive sprockets are installed on both sides of the rear drive shaft, powered by the second motor. A pair of front bearings are fixed to the top of the bag-changing device frame, with the driven sprocket connected to the front bearing via the front drive shaft. Several fixing holes are provided on the outer chain plate of the first drive chain, with several hooks and bag-carrying holes fixed in these holes, spaced one hole apart from each hook and bag-carrying hole. The mulberry leaf collection bag has a main bag body in the middle, a hook hole at the rear, an electromagnet at the front, and Velcro straps at the top front and back, with hooks hooked into the hook holes. When the first drive chain moves the hook hole above the first drive chain, the hook hole automatically detaches from the hook, transporting the next mulberry leaf collection bag to the original bag's position, thus completing one bag-changing cycle.

[0014] Furthermore, the bag-opening device specifically includes a fixed base, a linkage mechanism, a second chain and sprocket mechanism, a second electromagnet, a third transmission shaft, a third coupling, a third reducer, a third motor, and a third bearing. The linkage mechanism specifically includes a driving rod and a driven rod. The second chain and sprocket mechanism specifically includes a second driving sprocket, a second transmission chain, and a second driven sprocket. The third bearing specifically includes an upper bearing and a lower bearing.

[0015] Preferably, the reducer is fixed to the upper left of the bag-opening device frame and connected to the transmission shaft three via coupling two. Motor three is fixed below the reducer. Since the torque required for the linkage mechanism to rotate cannot be directly provided by motor three, the reducer here serves to reduce the output speed and increase the torque. Motor three provides power to the driving sprocket two. Driving sprocket two are installed in pairs on the left and right sides of the transmission shaft three, and driven sprocket two are installed in pairs in the middle of the fixed base. Driving rods are fixed in pairs on the sides of the fixed base. Driving sprocket two drives driven sprocket two to rotate, thereby driving the driving rod to rotate and causing the driven connecting rod to move. The upper bearing is fixed above the bag-opening device frame. The lower bearing is fixed below the bag-opening device frame. The front of the driven connecting rod is connected to the driving rod in pairs, and the rear is fixed in pairs on the side of the lower bearing. When the driving rod rotates, the top of the driven connecting rod makes an arc motion. Electromagnet two are fixed in pairs on the top of the driven connecting rod. When the driven link moves to the rear limit position, electromagnet two attracts electromagnet one, and when the driven link moves to the front limit position, the main bag opens.

[0016] Furthermore, a bag-discharging device is installed above the base plate, specifically including a motor, a transmission belt, a housing, a transmission shaft, a pressure sensor, and a bag-discharging base plate. The transmission shaft is fixed in pairs to the end of the housing, powered by the motor to drive the transmission belt, and the pressure sensor is installed above the bag-discharging base plate.

[0017] Preferably, when the pressure sensor detects that the weight of the mulberry leaf collection bag exceeds 10 kg (approximately two-thirds of the bag's full load), the transfer device and the material guiding device stop operating, halting the transport of mulberry leaves to the collection bag. Simultaneously, the drive chain moves forward one fixed hole's distance, and the hook attaching to the mulberry leaf collection bag reaches the position of the original bag transport hole, pushing the rear of the bag forward for a tighter packing. The rotating drive rod of the bag-opening device's linkage mechanism drives the driven link to move, bringing the front of the opened mulberry leaf collection bag towards the rear, using Velcro to complete the packing. After packing, the drive chain moves forward again one fixed hole's distance. At this point, the hook attaching to the spare mulberry leaf collection bag moves back to the original position of the hook attaching to the full mulberry leaf collection bag. The hook attaching to the full mulberry leaf collection bag automatically disengages from the hook hole. When electromagnet two is de-energized, its magnetic connection with electromagnet one is broken, and the bag-discharging device automatically discharges the packaged mulberry leaf collection bags. When power is restored to electromagnet two, its magnetic connection with electromagnet one is restored, the bag-opening device opens the main bag, and the transfer device and material guiding device resume operation, starting a new round of work.

[0018] The beneficial effects of this invention are as follows: This invention can automatically pick up mulberry leaves, automatically guide the leaves to a mulberry leaf collection bag, automatically pack and discharge the full bag, and automatically open a new bag for the next round of work—all processes are completed automatically. This invention avoids problems such as blockages during the leaf feeding process and overflows from the collection bag due to untimely bag changes. This invention can be used in conjunction with mulberry leaf harvesting machines, improving the mechanization level of mulberry orchards, reducing labor costs, and solving the problem of the lack of a suitable automatic collection, bagging, and packing device after manual or mechanized mulberry leaf harvesting, thus providing a foundation for large-scale mulberry harvesting.

[0031] The invention will now be described in detail with reference to the accompanying drawings. The directions described below, such as up, down, left, right, front, and back, are related to... Figure 1 The directions of the projection relationship are consistent in all directions: up, down, left, right, front, and back.

[0032] The present invention and its embodiments are described below. This description is not restrictive, and actual embodiments are not limited thereto. In short, if those skilled in the art are inspired by this description and, without departing from the spirit of the invention, design similar structures and embodiments to this technical solution, such designs should fall within the protection scope of the present invention.

[0033] The present invention discloses an automated mulberry leaf collection and baling machine, characterized in that the main body of the device is composed of six coordinated parts, including a fixed frame (10), a transfer device (20), a material guiding device (30), a bag changing device (40), a bag opening device (50), and a base plate (60). The transfer device (20) is equipped with a leaf-receiving umbrella (22) at the top, which is controlled by an electric push rod (24). When the leaf-receiving umbrella (22) is pushed upward, the telescopic frame (21) extends to receive the picked mulberry leaves; when the electric push rod (24) retracts downward, the telescopic frame (21) retracts to transport the mulberry leaves to the material guiding device (30). The material guiding device (30) is equipped with a box (31) in the middle, and an anti-blocking mechanism (32) is provided above the box (31). The material guiding device (30) transports the mulberry leaves to the mulberry leaf collection bag (41), and during the process, the rotating blade (322) continuously rotates to prevent the mulberry leaves from blocking the inclined surface of the box (31). The bag changing device (40) includes a second motor (46), a chain and sprocket mechanism (42), and a mulberry leaf collection bag (41). The second motor (46) drives the chain and sprocket mechanism (42) to move, sending the mulberry leaf collection bag (41) filled with mulberry leaves forward so that the bag discharge device (61) can discharge the mulberry leaf collection bag (41) filled with mulberry leaves and replace it with a new mulberry leaf collection bag (41). The bag opening device (50) includes a linkage mechanism (52), a third motor (58), a second electromagnet (54), and a second chain and sprocket mechanism (53). Motor 3 (58) drives chain sprocket mechanism 2 (53), which drives electromagnet 2 (54) fixed on driven link (522) to move towards electromagnet 1 (413). After electromagnet 2 (54) is attracted to electromagnet 1 (413), it moves back to its original position, opening the mulberry leaf collection bag (41) to receive mulberry leaves. It should be noted that the material guiding device (30) and the transfer device (20) must start working after the mulberry leaf collection bag (41) is opened. A pressure sensor (615) is installed on the bag discharge device (61) of the bottom plate (60). When the pressure sensor (615) senses that the weight of the mulberry leaf collection bag (41) exceeds 10kg (about two-thirds of the full load of the mulberry leaf collection bag), the transfer device (20) and the material guiding device (30) stop working, pausing the transportation of mulberry leaves to the mulberry leaf collection bag (41). Simultaneously, the first transmission chain (422) moves forward by one fixing hole (423) distance, and the hook of the mulberry leaf collection bag (41) reaches the position of the original bag transport hole (426), pushing the rear side of the mulberry leaf collection bag (41) forward to make the packing tighter. The active rod (521) of the linkage mechanism (52) of the bag opening device (50) rotates, driving the driven rod (522) to move, bringing the front side of the opened mulberry leaf collection bag (41) closer to the rear side of the mulberry leaf collection bag (41), and completing the packing of the mulberry leaf collection bag (41) using Velcro (414). After packing is completed, the first transmission chain (422) moves forward again by one fixing hole (423) distance.At this time, the hook (425) attached to the spare mulberry leaf collection bag (41) and the bagging and transporting hole (426) move to the original position of the hook (425) attached to the mulberry leaf collection bag (41) filled with mulberry leaves and the bagging and transporting hole (426). The hook (425) attached to the mulberry leaf collection bag (41) filled with mulberry leaves automatically disengages from the hook hole (412). Electromagnet II (54) is de-energized, and the magnetic connection with electromagnet I (413) is broken. The bag discharge device (61) automatically discharges the packaged mulberry leaf collection bag (41). Electromagnet II (54) is powered back on, and the magnetic connection with electromagnet I (413) is restored. The bag opening device (50) opens the main bag body (411), and the transfer device (20) and the material guiding device (30) resume operation, starting a new round of work.

[0034] According to the embodiment, the adapter (20) is described in detail below. The adapter (20) specifically includes a telescopic frame (21), a leaf-receiving canopy (22), a connecting rod (23), and an electric push rod (24). The telescopic frames (21) are installed in pairs on the side of the adapter frame (11). The leaf-receiving canopy (22) is set above the telescopic frames (21). A connecting rod (23) is set at the front and back of the telescopic frames (21).

[0035] Advantageously, an electric push rod (24) is installed below the telescopic frame (21). When the electric push rod (24) is pushed upward, the telescopic frame (21) extends, and the telescopic frame (21) drives the leaf-collecting canopy (22) to extend to the right; when the electric push rod (24) is pulled downward, the telescopic frame (21) retracts, and the retracting frame (21) drives the leaf-collecting canopy (22) to retract to the left. When the leaf-collecting canopy (22) extends, it receives the harvested mulberry leaves; when the leaf-collecting canopy (22) retracts, it transports the mulberry leaves to the feeding device (30).

[0036] According to the embodiment, the material guiding device (30) is described in detail below. The material guiding device (30) specifically includes a housing (31) and an anti-blocking mechanism (32). The anti-blocking mechanism (32) specifically includes a bearing (321), a rotating blade (322), a transmission shaft (323), and a motor (324). The housing (31) is installed in the middle of the material guiding device frame (12), and the two sides of the housing (31) are fixed to the two sides of the material guiding device frame (12). The rear side of the housing (31) is fixed to the rear side of the material guiding device frame (12).

[0037] Advantageously, bearings (321) are fixed in pairs on both sides of the housing (31). A motor (324) is installed on the left side of the housing (31), and bearings (321) are installed on both sides of the drive shaft (323). The motor (324) drives the drive shaft (323) to rotate, thereby driving the rotating blade (322) to rotate. The rotating blade (322) can transport the mulberry leaves stuck on the inclined surface of the housing (31) to the mulberry leaf collection bag (41), which has the effect of preventing blockage. After the transfer device (20) transfers the mulberry leaves to the housing (31), the rotating blade (322) rotates to transport the mulberry leaves to the mulberry leaf collection bag (41), while preventing the mulberry leaves from blocking the housing (31).

[0038] According to the embodiment, the bag changing device (40) is described in detail below. The bag changing device (40) specifically includes a mulberry leaf collection bag (41), a chain and sprocket mechanism (42), a bearing (43), a transmission shaft (44), a coupling (45), and a motor (46). The bearing (43) specifically includes a front bearing (431) and a rear bearing (432). The chain and sprocket mechanism (42) specifically includes a driven sprocket (421), a transmission chain (422), a fixing hole (423), a driving sprocket (424), a hook (425), and a bag-carrying hole (426). The transmission shaft (44) specifically includes a rear transmission shaft (441) and a front transmission shaft (442). The mulberry leaf collection bag (41) specifically includes a main bag body (411), a hook hole (412), an electromagnet (413), and Velcro (414).

[0039] Advantageously, the second motor (46) is fixed to the upper left of the bag changing device frame (13). A pair of rear bearings (432) are fixed to the upper rear side of the bag changing device frame (13), with the left rear bearing (432) connected to the second drive shaft (44), which is installed in the rear bearing (432) and connected to the second motor (46) via a coupling (45). A pair of drive sprockets (424) are installed on both sides of the rear drive shaft (441), powered by the second motor (46). A pair of front bearings (431) are fixed above the bag changing device frame (13), with the driven sprocket (421) connected to the front bearing (431) via the front drive shaft (442). Several fixing holes (423) are provided on the outer chain plate of the first transmission chain (422). Several hooks (425) and bagging and transporting holes (426) are fixed on the fixing holes (423). Each hook (425) is separated from the bagging and transporting hole (426) by one fixing hole (423). The mulberry leaf collection bag (41) has a main bag body (411) in the middle, a hook hole (412) at the rear, an electromagnet (413) at the front, and Velcro (414) at the top front and back. The hooks (425) are hooked in the hook holes (412). When the first transmission chain (422) drives the hook hole (412) to move above the first transmission chain (422), the hook hole (412) automatically detaches from the hook (425) and transports the next mulberry leaf collection bag (41) to the position of the original mulberry leaf collection bag (41), thus completing one bag changing cycle.

[0040] According to the embodiment, the bag-opening device (50) is described in detail below. The bag-opening device (50) specifically includes a fixed base (51), a linkage mechanism (52), a chain and sprocket mechanism two (53), an electromagnet two (54), a transmission shaft three (55), a coupling two (56), a reducer (57), a motor three (58), and a bearing three (59). The linkage mechanism (52) specifically includes a driving rod (521) and a driven connecting rod (522). The chain and sprocket mechanism two (53) specifically includes a driven sprocket two (531), a transmission chain two (532), and a driving sprocket two (533). The bearing three (59) specifically includes an upper bearing (591) and a lower bearing (592).

[0041] Advantageously, the reducer (57) is fixed to the upper left of the bag-opening device frame (14) and connected to the transmission shaft (55) via coupling two (56). The motor three (58) is fixed below the reducer (57). Since the torque required for the rotation of the linkage mechanism (52) cannot be directly provided by the motor three (58), the reducer (57) here plays the role of reducing the output speed and increasing the torque. The motor three (58) provides power to the drive sprocket two (533). The drive sprocket two (533) is installed in pairs on the left and right sides of the transmission shaft three (55), and the driven sprocket two (531) is installed in pairs in the middle of the fixed seat (51). The drive rod (521) is fixed in pairs on the side of the fixed seat (51). The drive sprocket two (533) drives the driven sprocket two (531) to rotate, thereby driving the drive rod (521) to rotate, which in turn drives the driven connecting rod (522) to move. The upper bearing (591) is fixed above the bag-opening device frame (14). The lower bearing (592) is fixed below the bag-opening device frame (14). The driven connecting rod (522) is connected to the driving rod (521) in pairs on the front side and fixed to the side of the lower bearing (592) in pairs on the rear side. When the driving rod (521) rotates, the top of the driven connecting rod (522) makes an arc motion. The second electromagnet (54) is fixed to the top of the driven connecting rod (522) in pairs. When the driven connecting rod (522) moves to the rear limit position, the second electromagnet (54) attracts the first electromagnet (413), and when the driven connecting rod (522) moves to the front limit position, the main bag body (411) opens.

[0042] According to the embodiment, the base plate (60) is described in detail below. A bag-discharging device (61) is provided on the top of the base plate (60). The bag-discharging device (61) specifically includes a motor (611), a transmission belt (612), a housing (613), a transmission shaft (614), a pressure sensor (615), and a bag-discharging base plate (616). The transmission shaft (614) is fixed in pairs at the ends of the housing. It is powered by the motor (611) to drive the transmission belt (612) to move. The pressure sensor (615) is installed above the bag-discharging base plate (616).

[0043] Advantageously, when the pressure sensor (615) senses that the weight of the mulberry leaf collection bag (41) exceeds 10 kg (approximately two-thirds of the full load of the mulberry leaf collection bag), the transfer device (20) and the material guide device (30) stop working, pausing the transport of mulberry leaves to the mulberry leaf collection bag (41). At the same time, the transmission chain (422) moves forward by the distance of one fixed hole (423), and the hook of the mulberry leaf collection bag (41) reaches the position of the original bag transport hole (426), pushing the rear side of the mulberry leaf collection bag (41) forward to make the packing tighter. The active rod (521) of the linkage mechanism (52) of the bag opening device (50) rotates, driving the driven rod (522) to move, bringing the front side of the opened mulberry leaf collection bag (41) closer to the rear side of the mulberry leaf collection bag (41), and completing the packing of the mulberry leaf collection bag (41) using Velcro (414). After packaging is completed, the first transmission chain (422) moves forward again by the distance of one fixed hole (423). At this time, the hook (425) attached to the spare mulberry leaf collection bag (41) and the bagging and transporting hole (426) move to the original position of the hook (425) attached to the full mulberry leaf collection bag (41) and the bagging and transporting hole (426). The hook (425) attached to the full mulberry leaf collection bag (41) automatically disengages from the hook hole (412). The second electromagnet (54) is de-energized, and the magnetic connection with the first electromagnet (413) is disconnected. The bag discharge device (61) automatically discharges the packaged mulberry leaf collection bag (41). Electromagnet 2 (54) resumes power supply and the magnetic connection with electromagnet 1 (413) is restored. The bag opening device (50) opens the main bag body (411), and the transfer device (20) and the material guiding device (30) resume operation, starting a new round of work.

[0044] The beneficial effects of this invention are as follows: This invention can automatically pick up mulberry leaves, automatically guide the leaves to a mulberry leaf collection bag, automatically pack and discharge the full bag, and automatically open a new bag for the next round of work—all processes are completed automatically. This invention avoids problems such as blockages during the leaf feeding process and overflows from the collection bag due to untimely bag changes. This invention can be used in conjunction with mulberry leaf harvesting machines, improving the mechanization level of mulberry orchards, reducing labor costs, and solving the problem of the lack of a suitable automatic collection, bagging, and packing device after manual or mechanized mulberry leaf harvesting, thus providing a foundation for large-scale mulberry harvesting.

[0045] It should be noted that the motor, drive shaft, coupling, and reducer in this invention are all installed in reasonable positions, and their parameters are selected based on existing technical means and actual needs.
