Description

Technical Field

[0001] This invention relates to an agricultural machinery device, and more specifically to an intermittent conveying mechanism for a tracked ramie harvester and baler. Background Technology

[0002] The cutting and conveying mechanism of the ramie harvester and baler is located at the front. The cutting and conveying mechanism consists of a chain conveyor and a cutting mechanism arranged from top to bottom. In front of the chain conveyor and the cutting mechanism, there is a ramie separating mechanism to guide the ramie. The ramie is guided to the cutting mechanism and cut at the root. The cut ramie is then conveyed to the side by the chain conveyor and baled by the baling mechanism at the outlet end before being output. The ramie distribution mechanism has multiple ramie conveying spaces. Ramie arrives at different lengths of the chain conveyor from these spaces and is then conveyed to the baling mechanism on one side. For the ramie conveying spaces near the baling mechanism, the corresponding chain conveyor not only receives the ramie that has just arrived but also receives the preceding ramie as it moves along. Therefore, the ramie conveying spaces closer to the baling mechanism become more crowded, which may affect normal ramie conveying. This necessitates a specific structural design to buffer the conveyed ramie at intervals and avoid congestion. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an intermittent conveying mechanism for a tracked ramie harvester and baler. The mechanism uses partitions to separate areas and then intermittently retracts or extends the partitions to achieve intermittent conveying of ramie, thereby alleviating the congestion of traditional conveying structures.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an interval conveying mechanism for a tracked ramie harvester and baler, comprising a frame, a chain conveying mechanism at the front of the frame, a seed-separating mechanism for dispersing and conveying ramie backwards at the front of the chain conveying mechanism, and a baling mechanism at the output end of the chain conveying mechanism; several groups of seed-separating mechanisms are arranged along the conveying direction of the chain conveying mechanism; the chain conveying mechanism includes a conveying chain wound in a ring, and the seed-separating mechanism includes a triangular plate and a lever gear disposed at its rear; several groups of triangular plates are spaced apart to form a first conveying channel for ramie to enter, the lever gear rotates at the rear of the first conveying channel to receive ramie and convey it to the conveying chain, and a second conveying channel for ramie conveying is formed between the triangular plates and the conveying chain; the mechanism also includes several groups of interval mechanisms, the number of which is... The spacing mechanism, including a spacer plate and a drive cylinder, is configured to correspond to the number and position of the first conveying channel. Several spacer plates extend from the conveying chain toward the first conveying channel. The drive cylinder is connected to the rear of the spacer plate to drive the spacer plate to retract or extend intermittently. When the spacer plate extends into the output end of the first conveying channel, it divides the first conveying channel into a conveying area where ramie can continue to be conveyed along the conveying chain, and a stopping area where ramie is blocked and buffered by the spacer plate. Ramie arriving at the output end from the input end of the first conveying channel is separated and enters the conveying area and the stopping area respectively. Ramie conveyed from the previous conveying area along the second conveying channel arrives at the next stopping area and is buffered. When the conveying chain is running, the drive cylinder intermittently retracts or extends the spacer plate. When the spacer plate retracts, it releases the ramie in the stopping area to continue to be conveyed. When it extends, it re-buffers the ramie.

[0005] As an improvement, both sides of the partition plate are set as inclined surfaces, thus making the cross-section of the partition plate conical. The inclined surface on the side where the dwell area is located is used to guide the movement of the buffered ramie away from the conveyor chain, and the inclined surface on the side where the conveying area is located is used to guide the ramie conveyed from the first conveying channel to move closer to the conveyor chain and the second conveying channel.

[0006] As an improvement, the conveyor chain is evenly equipped with feeding teeth for conveying ramie by resisting it. The frame is equipped with a first sensor at the position of the corresponding triangular plate to sense the arrival of the feeding teeth, and a second sensor at the position of the corresponding spacer plate to sense the departure of the feeding teeth. When the feeding teeth run to the position where they are sensed by the first sensor, the first sensor sends a feedback signal to the drive cylinder to drive the spacer plate to retract. When the feeding teeth run to the position where they are sensed by the second sensor, the first sensor sends a feedback signal to the drive cylinder to drive the spacer plate to extend.

[0007] As an improvement, the chain conveyor mechanism also includes sprockets for winding the conveyor chain and servo motors connected to the sprockets for power drive; the lever gear on one side of the triangular plate serves as the driving rotating wheel, and the servo motor is connected to the driving rotating wheel through a transmission mechanism; the lever gears on other triangular plates serve as driven rotating wheels, and the driven rotating wheels are connected to transmission gears at their triangular plates for linkage; when the driving rotating wheel rotates, its tooth structure drives its adjacent transmission gear to rotate, thereby driving the corresponding driven rotating wheel to rotate; when the driven rotating wheel rotates, its tooth structure drives its adjacent transmission gear to rotate, thereby sequentially transmitting power to make the subsequent driven rotating wheels rotate; the servo motor serves as the power source for the rotation of the driving rotating wheel, thereby driving the conveyor chain and lever gears synchronously.

[0008] As an improvement, the tooth structure of the feed teeth and the lever gear is set to synchronously pass through the position of the second sensor during operation.

[0009] As an improvement, a first gear is coaxially mounted on the passive rotating wheel, and a second gear is coaxially mounted on the transmission gear. The first gear and the second gear mesh with each other, thereby enabling the passive rotating wheel and the transmission gear to move in tandem.

[0010] As an improvement, the number of teeth on the active rotating wheel, the passive rotating wheel, and the transmission gear are the same. The teeth on the active rotating wheel and the passive rotating wheel have arc-shaped ends. After the arc-shaped ends of the active rotating wheel and the passive rotating wheel rotate into the tooth structure of the transmission gear, their front parts abut against the tooth structure of the transmission gear to rotate.

[0011] As an improvement, the transmission mechanism includes a transmission wheel that is connected and linked to the servo motor and the active rotating wheel, and a transmission chain that meshes with the transmission wheel.

[0012] The beneficial effects of this invention are as follows: By setting up an interval conveying mechanism, a diversion of ramie conveying is formed at the outlet position of the first conveying channel, allowing a portion of the ramie to enter the normal conveying of the second conveying channel first. Then, by intermittently retracting or extending the interval plate, the buffered ramie is allowed to enter the normal conveying of the second conveying channel in an orderly manner. This avoids the chaotic situation when the first and second conveying channels converge simultaneously in the traditional structure. While achieving a buffering effect, it also helps to ensure the neat arrangement of the ramie and avoid the occurrence of chaos. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , 2As shown in Figures 3, 4, and 5, a specific embodiment of the interval conveying mechanism of the tracked ramie harvester and baler of the present invention is presented. It includes a frame 0, a chain conveying mechanism 1 at the front of the frame 0, a seed-separating mechanism 2 for dispersing and conveying ramie backwards at the front of the chain conveying mechanism 1, and a baling mechanism 3 at the output end of the chain conveying mechanism 1. Several groups of seed-separating mechanisms 2 are arranged along the conveying direction of the chain conveying mechanism 1. The chain conveying mechanism 1 includes a conveying chain 11 wound in a ring. The seed-separating mechanism 2 includes a triangular plate 21 and a lever gear 22 located at its rear. Several groups of triangular plates 21 are spaced apart to form a first conveying channel 01 for ramie to enter. The lever gear 22 rotates at the rear of the first conveying channel 01 to receive ramie and convey it to the conveying chain 11. A second conveying channel 02 for ramie conveying is formed between the triangular plates 21 and the conveying chain 11. Several groups of interval mechanisms 4 are also included, the number and position of which correspond to the number of the first conveying channels 01. Corresponding to the position, the spacing mechanism 4 includes a spacing plate 41 and a drive cylinder 42. Several spacing plates 41 extend from the conveyor chain 11 toward the first conveying channel 01. The drive cylinder 42 is connected to the rear of the spacing plates 41 to drive the spacing plates 41 to intermittently retract or extend. When the spacing plates 41 extend into the output end of the first conveying channel 01, they divide the first conveying channel 01 into a conveying area 011 where ramie can continue to be conveyed along the conveyor chain 11, and an area where ramie is blocked by the spacing plates 41. The ramie from the input end of the first conveying channel 01 to the output end is separated and enters the conveying area 011 and the dwell area 012 respectively. The ramie conveyed from the previous conveying area 011 along the second conveying channel 02 arrives at the next dwell area 012 and is buffered. When the conveying chain 11 is running, the drive cylinder 42 intermittently retracts or extends the partition plate 41. When the partition plate 41 retracts, it releases the ramie in the dwell area 012 and continues to convey it backward. When it extends, the ramie is buffered again.

[0021] In use, this invention is applied to a tracked ramie harvester and baler. This ramie harvester and baler has mechanical power, and the user sits in the driver's control position A to control the machine's movement and the operation of various components. Tracked wheels B serve as the machine's traveling mechanism, providing excellent support for the entire machine. When operating the ramie harvester and baler, the driver aligns the machine's front end with the ramie clump to be harvested, and then drives the machine towards the ramie clump. The ramie enters the separating mechanism 2, where it is separated by several triangular plates 21 and enters each of the first conveying channels 01. Upon reaching the lever gear 22, the lever gear 22 rotates, driving the ramie towards the output end of the first conveying channel 01. The ramie then reaches the chain conveyor mechanism 1 below... When the cutting mechanism (not shown in the figure, referring to the prior art) is used, the ramie roots are cut by the cutting mechanism; the cut ramie enters the second conveying channel 02 and is driven by the second conveying channel 02 to be transported to the output end, and then finally enters the baling mechanism 3. After the number of ramie reaches the rated standard, the baling mechanism 3 completes the knotting of the ramie stalks. The baled ramie is output to the side of the ramie harvesting and baling machine and falls down, thus completing the overall ramie harvesting and baling process. As an innovation of this invention, an intermittently retractable partition plate 41 controlled by a drive cylinder 42 is provided, thereby separating the arriving ramie at the output end of the first conveying channel 01, dividing the ramie into two parts. The part that reaches the conveying area 011 continues to be conveyed, while the part that reaches the dwell area 012 is temporarily stored. Furthermore, the ramie conveyed in the second conveying channel 02 is also blocked and temporarily stored when it reaches the next partition plate 41. The retraction frequency of the partition plate 41 can be flexibly adjusted according to the density of ramie conveying, allowing a portion of the ramie to smoothly enter the second conveying channel 02 from the conveying area 011 first. Then, the retracted partition plate 41 releases the buffered ramie, and the buffered ramie then orderly enters the second conveying channel 02 for normal conveying. This avoids the increasingly chaotic situation in traditional structures where several first conveying channels 01 and second conveying channels 02 converge.

[0022] As an improved specific implementation, both the left and right sides of the partition plate 41 are set as inclined surfaces, thereby making the cross-section of the partition plate 41 conical. The inclined surface on the side where the dwell area 012 is located is used to guide the buffered ramie to move away from the conveyor chain 11, and the inclined surface on the side where the conveyor area 011 is located is used to guide the ramie conveyed from the first conveyor channel 01 to move closer to the conveyor chain 11 and the second conveyor channel 02.

[0023] like Figure 1As shown, the inclined surfaces on both sides facilitate the guidance of the ramie fibers, thereby allowing the first conveying channel 01 to smoothly separate and convey the fibers to the conveying area 011 and the dwell area 012. Furthermore, when the ramie fibers conveyed in the preceding sequence reach the subsequent dwell area 012, they can move away from the conveying chain 11 along the inclined surface of the partition plate 41, thus avoiding being carried by the conveying chain 11 and being more stably buffered in the space of the dwell area 012. They are then released and conveyed again when the partition plate 41 retracts. On the other hand, the partition plate 41 has a conical cross-sectional shape, which allows it to be inserted more smoothly into the gaps in the ramie stalks when extended, completing its repositioning and further separating the conveying area 011 and the dwell area 012.

[0024] As an improved specific implementation, the conveyor chain 11 is uniformly provided with feeding teeth 111 for conveying ramie by contacting it. The frame 0 is provided with a first sensor 112 at the position corresponding to the triangular plate 21 for sensing the arrival of the feeding teeth 111. The frame 0 is provided with a second sensor 113 at the position corresponding to the spacer plate 41 for sensing the departure of the feeding teeth 111. When the feeding teeth 111 run to the point where they are sensed by the first sensor 112, the first sensor 112 sends a signal to the drive cylinder 42 to drive the spacer plate 41 to retract. When the feeding teeth 111 run to the point where they are sensed by the second sensor 113, the first sensor 112 sends a signal to the drive cylinder 42 to drive the spacer plate 41 to extend.

[0025] like Figure 1 As shown, the optimized drive for the extension and retraction of the spacer plate 41 is achieved by coordinating the operation of the feeding teeth 111 with the sensing of the first sensor 112 and the second sensor 113 to achieve a stable ramie conveying effect. The feeding teeth 111 can push the ramie to move in an orderly manner in the second conveying channel 02. Its movement will cause the ramie to gradually accumulate in the dwell area 012. Therefore, when the feeding teeth 111 are sensed by the first sensor 112, the feedback signal is sent to the drive cylinder 42 to drive the spacer plate 41 to retract. At this time, the open space facilitates the feeding teeth 111 to continuously push the ramie to the output end. When the feeding teeth 111 are sensed by the second sensor 113, the feedback signal is sent to the drive cylinder 42 to drive the spacer plate 41 to extend. The spacer plate 41 re-separates the conveying area 011 and the dwell area 012. At this time, the feeding teeth 111 have passed the position of the spacer plate 41 without affecting the re-buffering of the ramie in the dwell area 012. By linking the operation of the feeding teeth 111 with the extension and retraction of the partition plate 41, the gradual accumulation and release of ramie buffer can be well controlled to continue conveying, making the ramie conveying stable and orderly, and preventing accumulation and compression.

[0026] As an improved specific implementation, the chain conveyor mechanism 1 also includes a sprocket 12 for winding the conveyor chain 11, and a servo motor 13 connected to the sprocket 12 for power drive; the lever gear 22 on the triangular plate 21 on one side serves as the active rotating wheel 221, and the servo motor 13 is connected to the active rotating wheel 221 through the transmission mechanism 14; the lever gears 22 on the other triangular plates 21 serve as passive rotating wheels 222, and the passive rotating wheels 222 are connected to the transmission gears 23 at their triangular plates 21 for linkage; when the active rotating wheel 221 rotates, its tooth structure drives its adjacent transmission gear 23 to rotate, thereby driving the corresponding passive rotating wheel 222 to rotate; when the passive rotating wheel 222 rotates, its tooth structure drives its adjacent transmission gear 23 to rotate, thereby sequentially transmitting power to make the subsequent passive rotating wheel 222 rotate; the servo motor 13 serves as the power source for the rotation of the active rotating wheel 221, thereby causing the conveyor chain 11 and the lever gear 22 to be driven synchronously.

[0027] like Figure 1 , 2 As shown in Figure 3, when the ramie reaches the lever gear 22, the rotating lever gear 22 actively drives the ramie towards the output end of the first conveying channel 01. This active driving force effectively resists the rear of the ramie. When the ramie reaches the cutting mechanism below the chain conveyor mechanism 1, this active resisting driving force allows the root of the ramie to be better cut by the cutting mechanism. Through innovative structural design, a servo motor 13 is used to drive the rotation of a set of lever gears 22. It acts as the active rotating wheel 221, and by rotating, it drives the adjacent transmission gear 23, thereby driving the adjacent passive rotating wheel 222, that is, as shown in Figure 3. Figure 1 , 2 Taking the three first conveying channels 01 as an example, the active rotating wheel 221, transmission gear 23, passive rotating wheel 222, and passive rotating wheel 222 transmit power sequentially, realizing the active driving function of all lever gears 22. This makes the ramie conveyed to the output end of the first conveying channel 01 more effective and stable, which is conducive to the stable cutting of the ramie root by the cutting mechanism. The cut ramie is conveyed by the active resistance and support of the lever gears 22, which can avoid the tilting state caused by the sparse ramie. The ramie entering the second conveying channel 02 is more neat and orderly, which is conducive to the neat and orderly ramie of the final baling, ensuring the quality of conveying and baling.

[0028] The above implementation method effectively controls component costs. The servo motor 13 directly serves as the power source, driving the active operation of multiple sets of lever gears 22. Specifically, the active rotating wheel 221 can be positioned near the output end of the second conveying channel 02, i.e., the side where the bundling mechanism 3 is located, adapting to the original rotation direction of the lever gears 22. This allows it to sequentially drive the rotation of adjacent lever gears 22. The rotation of each lever gear 22 effectively and actively contacts the ramie, completing the transport from the first conveying channel 01 to the second conveying channel 02. Combined with the conveying power provided by the chain conveyor mechanism 1 at the rear, the ramie is transported stably. The rotation of the lever gears 22 in the second conveying channel 02 effectively pushes the ramie, and structurally, its rotation returns to its location within the triangular plate 21, preventing it from entering the adjacent first conveying channel 01 and interfering with the ramie transport. Choosing a servo motor 13 as the power source for the active rotating wheel 221 allows the conveyor chain 11 and each lever gear 22 to operate synchronously. This ensures a high degree of speed consistency between the conveyor chain 11, its feeding teeth 111, and the lever gears 22 during operation, stabilizing the continuous conveying of ramie and improving the synchronization of component operation. During the operation of the ramie harvester and baler, the ramie continuously reaches the lever gear 22. If the passive rotating wheel 222 is propelled forward by the ramie's contact with it, causing the passive rotating wheel 222 and the transmission gear 23 to rotate forward, the active rotating wheel 221 can catch up with the transmission gear 23 during its continuous active operation, thus synchronously driving the transmission gear 23 and the subsequent passive rotating wheel 222.

[0029] As an improved specific implementation, the tooth structure of the feeding tooth 111 and the lever gear 22 is configured to synchronously pass through the position of the second sensor 113 during operation.

[0030] This embodiment is not shown in the figure. In specific implementation, the feeding tooth 111 and the lever gear 22 operate synchronously. The tooth structure of the lever gear 22 is set to pass through the position of the second sensor 113 synchronously with the feeding tooth 111. In this way, they can cooperate to push the ramie to the conveying area 011 synchronously when the spacer plate 41 retracts. After the tooth structures of the feeding tooth 111 and the lever gear 22 have both passed through the spacer plate 41, the spacer plate 41 extends again without affecting the re-buffering of the ramie in the dwell area 012.

[0031] As an improved specific implementation, the passive rotating wheel 222 is coaxially provided with a first gear 231, and the transmission gear 23 is coaxially provided with a second gear 232. The first gear 231 and the second gear 232 mesh with each other, thereby causing the passive rotating wheel 222 and the transmission gear 23 to move together.

[0032] like Figure 1 , 2As shown in Figure 3, the first gear 23 and the second gear 232 are rotatably mounted on the triangular plate 21 via a shaft structure. Their meshing enables the linkage between the driven rotating wheel 222 and the transmission gear 23. The driven rotating wheel 222 has a relatively long tooth structure; therefore, in the structural design, it is offset from the transmission gear 23 in the height direction, i.e., as shown in Figure 3. Figure 3 As shown, the active rotating wheel 221 engages with the adjacent first transmission gear 23 at the same height for transmission. The first transmission gear 23 and the meshing first passive rotating wheel 222 are at different heights, with the first passive rotating wheel 222 positioned lower to avoid interference with the first transmission gear 23 during rotation. Conversely, the first passive rotating wheel 222 engages with the adjacent second transmission gear 23 at the same height for transmission. The second transmission gear 23 and the meshing second passive rotating wheel 222 are at different heights, with the second passive rotating wheel 222 positioned lower to avoid interference with the second transmission gear 23 during rotation. The conveyor chain 11, along with the feeding teeth 111, the lever gear 22, and the drive cylinder 42, are designed as follows... Figure 3 The structures shown are set at different heights and will not cause structural interference during operation.

[0033] As an improved specific implementation, the number of teeth on the active rotating wheel 221, the passive rotating wheel 222, and the transmission gear 23 is the same. The teeth on the active rotating wheel 221 and the passive rotating wheel 222 have arc-shaped ends 223. After the arc-shaped ends 223 of the active rotating wheel 221 and the passive rotating wheel 222 rotate into the tooth structure of the transmission gear 23, their front parts abut against the tooth structure of the transmission gear 23 to rotate.

[0034] like Figure 1 , 2 As shown in Figure 3, the number of teeth in the active rotating wheel 221, the passive rotating wheel 222, and the transmission gear 23 are all set to 4-6. Each tooth in the active rotating wheel 221 drives the passive rotating wheel 222 and the transmission gear 23 to rotate approximately 90-60 degrees during rotation. The teeth of the active rotating wheel 221 and the passive rotating wheel 222 have arc-shaped ends 223. These arc-shaped ends 223 gently contact the teeth of the transmission gear 23, preventing sharp corners during rotation and reducing hard impacts between the arc-shaped ends 223 and the transmission gear 23 during contact and movement, thus improving operational stability and reducing wear.

[0035] As an improved specific implementation, the transmission mechanism 14 includes a transmission wheel 141 that is connected and linked to the servo motor 13 and the active rotating wheel 221 respectively, and a transmission chain 142 that meshes with the transmission wheel 141.

[0036] like Figure 1 , 2As shown, in a specific implementation, the transmission wheel 141 and the transmission chain 142 are arranged and connected at the lower part of the frame 0, and an outer shell is provided to prevent debris from entering and interfering. This position is located on the side of the structure, avoiding the cutting mechanism, and can be arranged together with the adjacent bundling mechanism 3 through optimization, which facilitates the integrated layout of equipment components.

[0037] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
