Description

Technical Field

[0001] The present invention relates to the technical field of sugarcane planting devices, and in particular to an intelligent sugarcane bud-picking device. Background Art

[0002] In the process of sugarcane planting, the treatment of seed stems is one of the key steps. Among them, the bud removal process is of great significance for improving the emergence rate of sugarcane, reducing the spread of pests and diseases, and optimizing planting efficiency. The traditional manual bud removal method mainly relies on the experience of the operator to manually remove the excess buds on the sugarcane. However, this method has problems such as high labor intensity, low efficiency and poor consistency.

[0003] In recent years, with the development of mechanization technology, some mechanical equipment for sugarcane bud removal has appeared on the market. These devices usually cooperate with identification devices to identify the position, quality, etc. of sugarcane buds. After identification, mechanical cutters or other physical devices are used to remove the buds from one side of the sugarcane. However, the traditional single-sided bud removal method often requires additional mechanisms (such as rotating devices) to rotate the sugarcane for all-round bud removal of the sugarcane. This design not only increases the complexity of the equipment, but may also lead to increased operating costs, difficult maintenance, and reduced overall work efficiency. Summary of the invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Please refer to Figures 1 to 6An exemplary embodiment of the present invention provides a sugarcane intelligent bud picking device, which mainly includes a frame 10, a sugarcane conveying mechanism 20, an automatic identification mechanism 30, a bud picking device 40 and a controller.

[0044] The frame 10 is used to achieve support and is a frame structure as a whole, preferably welded from steel sections.

[0045] The sugarcane conveying mechanism 20 is arranged on the frame 10 for driving and conveying sugarcane, that is, the sugarcane is placed on the sugarcane conveying mechanism 20, so that the sugarcane conveying mechanism 20 can be conveyed to the bud-locking device 40 for bud-locking. The sugarcane conveying mechanism 20 can select an existing sugarcane conveying device, and only needs to be able to realize the linear conveying of sugarcane. In this exemplary embodiment, the sugarcane conveying mechanism 20 includes a conveying wheel group and a conveying driving mechanism for driving the conveying wheel group to rotate. The conveying wheel group is a plurality of groups, and each conveying wheel group includes an upper pressing wheel 21 and a lower pressing wheel 22. The upper pressing wheel 21 is located above the lower pressing wheel 22, and the upper pressing wheel 21 and the lower pressing wheel 22 are both provided with grooves, and the grooves of the upper pressing wheel 21 and the lower pressing wheel 22 form a space for placing sugarcane. The lower pressing wheel 22 is rotatably mounted on the frame 10 through a rotating shaft, and the upper pressing wheel 21 is arranged on an adaptive clamping mechanism through a rotating shaft, and the adaptive clamping mechanism is located at both ends of the rotating shaft, and the adaptive clamping mechanism is mounted on the frame 10. The adaptive clamping mechanism includes a mounting bracket 23, a cross bar 24 and a tension spring 25. The mounting bracket 23 is fixedly mounted on the frame 10, and vertical slide grooves are provided on both sides. The two ends of the cross bar 24 are located in the slide grooves on both sides of the mounting bracket 23 so that the cross bar 24 can slide vertically along the slide grooves. The tension spring 25 is arranged on both ends of the cross bar 24, and the other end is connected to the frame 10 so that the cross bar 24 has a tendency to move downward. The two ends of the rotating shaft of the upper pressing wheel 21 are respectively connected to the cross bar 24. When the cross bar 24 has a tendency to move downward, the upper pressing wheel 21 also has a tendency to move downward, thereby pressing the sugarcane downward. The conveying drive mechanism includes a conveying drive motor 26 and a conveying transmission assembly. The conveying drive motor 26 is arranged on the frame 10. The conveying transmission assembly includes a synchronous belt 27 and two synchronous wheels 28. One synchronous wheel 28 is installed on the rotating shaft of the lower pressing wheel 22, and the other synchronous wheel 28 is installed on the output shaft of the driving motor 26. The synchronous belt 27 is sleeved on the two synchronous wheels 28, so that when the driving motor 26 is running, the rotating shaft of the lower pressing wheel 22 can be driven to rotate through the synchronous belt 27, thereby driving the lower pressing wheel 22 to rotate. During implementation, the sugar cane is prevented from being between the grooves of the upper pressing wheel 21 and the lower pressing wheel 22. The upper pressing wheel 21 has the function of pressing the sugar cane under the action of the adaptive clamping mechanism. When the lower pressing wheel 22 rotates, it can drive the sugar cane to move toward the bud buckling device 40.

[0046] Preferably, in some embodiments, multiple groups of conveying wheel groups share a driving motor 26. In this case, a synchronous wheel 28 is provided at the end of the rotating shaft of the lower pressure wheel 22 of the adjacent conveying wheel group. The two synchronous wheels 28 are directly sleeved with a synchronous belt 27. In this case, the rotating shaft of the lower pressure wheel 22 can be driven to rotate by the synchronous belt 27, thereby driving the lower pressure wheel 22 to rotate.

[0047] The automatic identification mechanism 30 is arranged on the frame 10 for identifying the sugarcane buds on the sugarcane. The automatic identification mechanism 30 adopts a device of the prior art and has a camera to identify the position of the sugarcane buds on the sugarcane by means of video or the like. The automatic identification mechanism 30 is arranged beside the conveying channel for the sugarcane conveying mechanism 20 to convey the sugarcane. In other words, a plurality of points are arranged on the entire path of the conveying channel for the sugarcane conveying mechanism 20 to convey the sugarcane. The automatic identification mechanism 30 identifies the position of the sugarcane buds on the sugarcane, accurately obtains the position of the sugarcane buds on the sugarcane, and can accurately send the sugarcane buds on the sugarcane to the bud-locking device 40 for bud-locking in combination with the conveying of the sugarcane by the sugarcane conveying mechanism 20.

[0048] The bud-locking device 40 is arranged on the frame 10. The bud-locking device 40 includes two bud-locking mechanisms 41 for realizing sugarcane bud locking. The two bud-locking mechanisms 41 are respectively located on both sides of the sugarcane driven and conveyed by the sugarcane conveying mechanism 20. The sugarcane buds of the sugarcane are located on both sides. During transportation, the sugarcane buds are transported in a manner of being located on both sides, so that when the sugarcane buds on one side of the sugarcane are located directly below the bud-locking mechanism 41 on the same side, the bud-locking mechanism 41 on the same side realizes the locking of the sugarcane buds, and when the sugarcane buds on the other side of the sugarcane are located directly below the bud-locking mechanism 41 on the same side, the bud-locking mechanism 41 on the same side realizes the locking of the sugarcane buds on the other side. The locking of the buds on both sides can be realized, so there is no need to use an additional mechanism to rotate the sugarcane so that the sugarcane buds on both sides are rotated to the bottom of the bud-locking mechanism 41 in turn to realize the locking of the buds, thereby reducing the use of mechanisms, reducing costs, reducing the difficulty of maintenance, and improving the overall bud-locking efficiency.

[0049] The controller is electrically connected to the sugarcane conveying mechanism 20, the automatic identification mechanism 30 and the bud-locking mechanism 41 respectively. The controller receives the signal of the automatic identification mechanism 30 to control the start and stop of the sugarcane conveying mechanism 20 and control the bud-locking mechanism 41 to lock the sugarcane buds on the sugarcane. For example, in an exemplary embodiment, the sugarcane conveying mechanism 20 conveys sugarcane to the bud-locking device 40 for bud-locking. During the conveying, the automatic identification mechanism 30 identifies the position of the sugarcane buds on the sugarcane and transmits the signal to the controller. Combined with the conveying speed of the sugarcane conveying mechanism 20, when the sugarcane buds are delivered to the right below the bud-locking mechanism 41 on the same side, the controller controls the sugarcane conveying mechanism 20 to temporarily stop and control the bud-locking mechanism 41 to lock the buds. Since the automatic identification mechanism 30 and the bud-locking mechanism 41 are provided on both sides, the sugarcane conveying mechanism 20 can be controlled to temporarily stop and control the bud-locking mechanism 41 to lock the buds when the sugarcane buds are located right below the bud-locking mechanism 41.

[0050] In a preferred embodiment, sensors may be installed on both sides of the lower side of the bud-holding mechanism 41 to perform multiple identifications of the sugarcane buds to ensure identification accuracy, so as to ensure that the sugarcane can be stopped and held by the bud-holding mechanism 41 when the sugarcane buds pass by.

[0051] The camera of the automatic identification mechanism 30 is arranged on the sugarcane conveying channel in front of the bud picking knife, and can take pictures of one sugarcane at a time. The bud picking can be carried out after taking pictures in advance and determining the position of the sugarcane buds.

[0052] In a preferred embodiment, one of the bud-locking mechanisms 41 is fixedly arranged on the frame 10, and the other bud-locking mechanism 41 is driven to move by the first driving mechanism, and the moving direction of the bud-locking mechanism 41 driven to move by the first driving mechanism is parallel to the conveying direction of the sugarcane. Considering that the bud point spacing on the sugarcane gradually increases from the head to the tail, that is, in the length direction of the sugarcane, the distribution spacing between the sugarcane buds is not equal, therefore, if both bud-locking mechanisms 41 are fixedly arranged, only one side of the bud can be locked at a time. Based on this, in order to simultaneously achieve bud locking on both sides, the bud locking device of the present invention has one bud locking mechanism 41 fixedly set on the frame 10, and the other bud locking mechanism 41 is driven to move by the first driving mechanism, and the moving direction is parallel to the conveying direction of the sugarcane. When the front sugarcane bud is located directly below the front bud locking mechanism 41, the position of the rear sugarcane bud is also determined. At this time, by moving the rear bud locking mechanism 41 to directly above the rear sugarcane bud, the two sugarcane buds are simultaneously located under the two bud locking mechanisms 41. By starting the bud locking mechanisms 41 at the same time, the sugarcane buds on both sides can be locked at the same time, thereby improving the bud locking efficiency.

[0053] The bud-locking device 40 of the present invention can lock the buds from both sides simultaneously. When locking the buds at the same time, since the two bud-locking mechanisms 41 apply force to both sides at the same time, the forces on both sides of the sugarcane are basically offset and the sugarcane will not rotate or sway. Therefore, there is no need to provide an additional tightening device, that is, it can cooperate with the sugarcane conveying mechanism 20 to ensure that the sugarcane is in a fixed position when the buds are locked. In the case of single-side bud locking, the bud-locking mechanism 41 on one side locks the bud, and the bud-locking mechanism 41 on the other side tightens the sugarcane from top to bottom, which can also ensure that the sugarcane is in a fixed position when the buds are locked.

[0054] The bud-locking device 40 further includes a support plate 42 , which is transversely mounted on the frame 10 . The support plate 42 is provided with bud-locking holes 43 at positions corresponding to the two bud-locking mechanisms 41 , and the bud-locking holes 43 penetrate the support plate 42 . The bud catching device 40 includes a bud catching device shell 411, and the bud catching mechanism 41 includes a bud catching driving mechanism 412 and a bud catching knife 413. The bud catching device shell 411 is installed on the support plate 42 and its bottom is open. The bud catching driving mechanism 412 is installed in the bud catching device shell 411. The bud catching driving mechanism 412 is preferably a linear driving mechanism such as a cylinder, a hydraulic cylinder or an electric push rod, which can realize the linear drive of the sugarcane bud catching knife 413. The sugarcane bud catching knife 413 is installed at the bottom of the bud catching driving mechanism 412 to be driven up and down by the bud catching driving mechanism 412. The sugarcane bud catching knife 413 is arranged opposite to the bud catching hole 43. When the sugarcane bud catching knife 413 catching the bud downwards, it can enter the bud catching hole 43, and the chopped sugarcane buds fall down from the bud catching hole 43.

[0055] In this exemplary embodiment, the bud-catching hole 43 corresponding to the fixed bud-catching mechanism 41 is a strip-shaped hole with a shorter length or, because the position of the bud-catching mechanism 41 is fixed, the vertical projection position of the sugarcane bud-catching knife 413 is fixed. At this time, the bud-catching hole 43 which is a strip-shaped hole with a shorter length just corresponds to the sugarcane bud-catching knife 413; the bud-catching hole 43 corresponding to the movable bud-catching mechanism 41 is a strip-shaped hole with a longer length. Because the position of the bud-catching mechanism 41 is movable, the vertical projection position of the sugarcane bud-catching knife 413 is not fixed. At this time, the bud-catching hole 43 which is a strip-shaped hole with a longer length can cover the moving position of the sugarcane bud-catching knife 413, ensuring that no matter where the bud is caught, it can be located above the bud-catching hole 43, so as to ensure that the sugarcane buds can fall down from the bud-catching hole 43.

[0056] The first driving mechanism includes a slide rail 441, a slider 442, a first driving motor 443 and a first screw rod 444. The slide rail 441 is fixedly installed in the bud-locking device housing 411. The extension direction of the slide rail 441 is parallel to the conveying direction of the sugarcane. The slider 442 is slidably installed in the slide rail 441 and is connected to the bud-locking driving mechanism 412 of the bud-locking mechanism 41 driven to move by the first driving mechanism. The first driving motor 443 is fixedly installed on the bud-locking device housing 411. The first screw rod 444 is connected to the first driving motor 443 to be driven to rotate by the first driving motor 443. The extension direction of the first screw rod 444 is consistent with the extension direction of the slide rail 441. A screw hole is opened on the slider 42, and the first screw rod 444 is connected to the slider 442 through the screw hole. During implementation, the first drive motor 443 drives the first screw rod 444 to rotate, and under the action of the first screw rod 444, the slider 442 can move along the slide rail 441, and the forward and reverse rotation can change the moving direction of the slider 442. The slider 442 is connected to the bud-locking driving mechanism 412, or in other words, the bud-locking driving mechanism 412 is installed on the slider 442 and is driven by the slider 442 to move above the corresponding sugarcane bud.

[0057] In a preferred embodiment, the sugarcane bud-catching knife 413 has a bud-catching knife accommodating cavity 414 extending upward from the bottom, and an elastic member 415 is arranged in the bud-catching knife accommodating cavity 414. The elastic member 415 is provided with a push piece 416 at a position close to the bottom opening of the bud-catching knife accommodating cavity 414. The commonly used sugarcane bud-catching knife 413 is circular or arc-shaped, with a thin and sharp bottom, and the cutting of sugarcane is achieved by the blade at the bottom to catch the sugarcane buds. When catching the buds, if the cut sugarcane buds are thin, the sugarcane buds will generally not stay in the circular or arc-shaped cavity of the sugarcane bud-catching knife 413 after catching the buds, and will fall directly. However, for some larger seed stems, they may stay in the circular or arc-shaped cavity of the sugarcane bud-catching knife 413, thereby affecting the falling of the sugarcane buds and the subsequent bud-catching. Based on this, the sugarcane bud-peeling knife 413 of the present invention has a bud-peeling knife accommodating cavity 414 extending upward from the bottom. When the bud is plucking, the entire sugarcane bud-peeling knife 413 moves downward quickly. Before the sugarcane bud is separated from the sugarcane, it will exert a force on the pushing piece 416 to compress the elastic member 415. After the sugarcane bud is cut and completely separated from the sugarcane, under the action of the elastic member 415, the pushing piece 416 is pushed to move toward the end of the sugarcane bud-peeling knife 413, and the sugarcane bud is pushed downward. In the above manner, it can be ensured that the sugarcane bud will not be retained in the sugarcane bud-peeling knife 413, thereby ensuring efficient bud plucking.

[0058] The frame 10 is provided with a first conveyor belt 11, which is located below the bud-binding hole 43. At this time, after the sugarcane buds are budded by the bud-binding knife 413 and fall from the bud-binding hole 43, they can fall onto the first conveyor belt 11 and be transported by the first conveyor belt 11. The frame 10 is provided with a second conveyor belt 11, which is located below the first conveyor belt 11, and the two ends of the second conveyor belt 11 are respectively located on both sides of the first conveyor belt 11. The bottom of the support plate 42 is provided with a rotating plate 45 and a second driving motor 46 for driving the rotating plate 45 to rotate beside the two bud-locking holes 43, so that when the second driving motor 46 drives the rotating plate 45 to rotate to an upright state, the bud-locking holes 43 are not blocked so that the sugarcane buds falling from the bud-locking holes 43 can fall directly onto the first conveyor belt 11, and when the second driving motor 46 drives the rotating plate 45 to rotate to an inclined state, the sugarcane buds falling from the bud-locking holes 43 can slide along the inclined rotating plate 45 onto the second conveyor belt 11. The two rotating plates 45 are located between the two bud-locking holes 43, and when rotating, the two rotating plates 45 rotate to the side, and the two rotating plates 45 cover the two bud-locking holes 43 one by one and do not cover the other bud-locking hole 43, that is, one rotating plate 45 can only affect one bud-locking hole 43. The identification device of the prior art can not only identify the position of the sugarcane buds, but also have a certain accuracy to identify the quality of the sugarcane buds. The automatic identification mechanism 30 adopts the identification device of the prior art. While identifying the position of the sugarcane buds, it can also identify the quality of the sugarcane buds. The automatic identification mechanism 30 extends to the vicinity of the two bud-locking mechanisms 41. After identifying the quality of the sugarcane buds of the corresponding bud-locking mechanisms, if the sugarcane buds are good buds, the second drive motor 46 maintains the rotating plate 45 in an upright state without blocking the bud-locking hole 43 so that the sugarcane buds falling from the bud-locking hole 43 can directly fall onto the first conveyor belt 11. At this time, the first conveyor belt 11 is used to transport good buds. If the sugarcane buds are bad buds, the buds are not locked, or the buds are still locked, but the second drive motor 46 drives the rotating plate 45 to rotate to an inclined state so that the sugarcane buds falling from the bud-locking hole 43 slide along the inclined rotating plate 45 onto the second conveyor belt 11. At this time, the second conveyor belt 11 is used to transport bad buds. In the above manner, good buds and bad buds can be transported separately. In this exemplary embodiment, even if the buds are identified as bad buds by the automatic identification mechanism 30, the buds are still selected for locking.

[0059] In a preferred embodiment, a first sugarcane bud identification mechanism 31 for identifying good and bad sugarcane buds is provided at the end attachment of the first conveyor belt 11. A dividing mechanism 50 for separating good sugarcane buds and bad sugarcane buds is provided below the end of the first conveyor belt 11. A third conveyor belt 13 is provided on the frame 10, and the front end of the third conveyor belt 13 is located below the discharge port of the dividing mechanism 50 for distributing bad sugarcane buds below the end of the first conveyor belt 11, and the end of the third conveyor belt 13 is located above the second conveyor belt 12. The dividing mechanism 50 includes a dividing hopper 51, a feeding port 52 is provided at the top of the dividing hopper 51, and two discharge ports 53 are provided at the bottom of the dividing hopper 51. A dividing motor 54 is provided on the dividing hopper 51, and a dividing plate 55 is provided on the output shaft of the dividing motor 54, which is used to block one of the discharge ports 53 and guide the material into the other discharge port 53.

[0060] Considering the problem of a certain accuracy in identifying good and bad buds, a first sugarcane bud identification mechanism 31 for identifying good and bad sugarcane buds is provided at the end of the first conveyor belt 11 to perform secondary identification on the sugarcane buds conveyed by the first conveyor belt 11. Since there are fewer interference factors at this position, the sorting accuracy can be improved. By setting up a sorting mechanism 50, if it is identified as a good bud, it enters through the feed port 52 of the sorting hopper 51 and exits from an outlet 53 of the sorting mechanism 50, and if it is identified as a bad bud, it enters through the feed port 52 of the sorting hopper 51, and the sorting motor 54 drives the sorting plate 55 to rotate to the other side, and the sugarcane buds exit from another outlet 53 of the sorting mechanism 50 and fall onto the third conveyor belt 13, and are transported by the third conveyor belt 13 and fall onto the second conveyor belt 12.

[0061] The second conveyor belt 12 is provided with a second sugarcane bud identification mechanism 32 for identifying good and bad sugarcane buds. A material separation mechanism 50 for separating good and bad sugarcane buds is provided below the end of the second conveyor belt 12. The structure of the material separation mechanism 50 here is consistent with the structure of the material separation mechanism 50 described above. By providing the material separation mechanism 50, good and bad sugarcane buds can be separated after the second sugarcane bud identification mechanism 32 identifies good and bad sugarcane buds.

[0062] A fourth conveyor belt 14 is provided on the frame 10 , and the front end of the fourth conveyor belt 14 is located below the discharge port of the distributing mechanism 50 for distributing bad sugarcane buds below the end of the second conveyor belt 12 , and the end of the fourth conveyor belt 14 is located below the end of the first conveyor belt 11 . By setting up a dividing mechanism 50 and cooperating with the fourth conveyor belt 14, if the sugarcane buds on the second conveyor belt 12 are identified as bad buds, they enter through the feed port 52 of the dividing hopper 51 and go out from an outlet 53 of the dividing mechanism 50; if they are identified as good buds, they enter through the feed port 52 of the dividing hopper 51, and the dividing motor 54 drives the dividing plate 55 to rotate to the other side. The sugarcane buds go out from the other outlet 53 of the dividing mechanism 50 and fall onto the fourth conveyor belt 14, and are transported by the fourth conveyor belt 14. The end of the fourth conveyor belt 14 is located below the end of the first conveyor belt 11. The first conveyor belt 11 and the fourth conveyor belt 14 are both used to transport good buds, and the end positions of the two are basically the same. The good sugarcane buds transported by the two fall from the ends and fall at basically the same position, which is conducive to the unified collection and processing of the good sugarcane buds.

After the bud-catching is completed, the bud-catching driving mechanism 412 drives the bud-catching knife 413 to reset upward, and the automatic identification mechanism 30 drives the sugarcane to move so that the subsequent two sugarcane buds are located at the position of the bud-catching device 40 for the next round of bud-catching; the automatic identification mechanism 30 identifies and distinguishes good buds from bad buds, and the second driving motor 46 maintains the rotating plate 45 in an upright state without covering the bud-catching holes 43 so that the sugarcane buds falling from the bud-catching holes 43 can fall directly onto the first conveyor belt 11. At this time, the first conveyor belt 11 is used to transport good buds, and if the identification mechanism 30 is used to identify and distinguish good buds from bad buds, ....

The good sugarcane buds go out directly through a discharge port 53 of the dividing mechanism 50, and the bad sugarcane buds fall onto the third conveyor belt 13 through another discharge port 53 under the action of the dividing motor 54 driving the dividing plate 55 to rotate and are transported by the third conveyor belt 11. 3 and fall onto the second conveyor belt 12; the sugarcane buds on the second conveyor belt 12 are identified by the second sugarcane bud identification mechanism 32 before falling from the end thereof, and the sugarcane buds falling from the end of the second conveyor belt 12 enter the dividing mechanism 50 near the end thereof, and are divided by the dividing mechanism 50, and the bad sugarcane buds directly go out through one discharge port 53 of the dividing mechanism 50, and the good sugarcane buds fall onto the fourth conveyor belt 14 through another discharge port 53 under the action of the dividing motor 54 driving the dividing plate 55 to rotate and are transported by the fourth conveyor belt 14, and the end of the fourth conveyor belt 14 is located below the end of the first conveyor belt 11, and the first conveyor belt 11 and the fourth conveyor belt 14 are both used to transport the good buds, and the falling positions are basically the same.

[0065] The intelligent sugarcane bud picking device of the present invention can realize bud picking on both sides, without the need to use an additional mechanism to rotate the sugarcane so that the sugarcane buds on both sides rotate in turn to be directly under the bud picking mechanism to realize bud picking, thereby reducing the use of mechanisms, reducing costs, reducing the difficulty of maintenance, and improving the overall bud picking efficiency. The position of the bud picking mechanism can be adjusted according to the position of the two sugarcane buds, and the two sugarcane buds can be picked at the same time to improve the bud picking efficiency. When a bad bud is identified by the recognition technology, it is directly transmitted forward without picking the bud, or the bud is picked first, and then the good buds and bad buds are collected respectively, and the collected sugarcane buds can be screened twice or three times.
