Description

Technical Field

[0001] This invention relates to the field of sugarcane planting technology, specifically to a sugarcane planting device. Background Technology

[0002] Sugarcane is a major economic crop grown in southern my country, known for its drought resistance and ease of management. Sugarcane cultivation involves several stages, including seed selection, germination, planting, and post-planting management. The quality of seed planting directly impacts the later stages of germination, growth, yield, and ratooning. Currently, sugarcane production in southern my country is predominantly hilly, and factors such as terrain, scale of cultivation, and specialization make large-scale mechanized planting difficult. However, after years of development, my country has made some progress in mechanized sugarcane cultivation, achieving mechanization in stages such as ditching, fertilization, soil covering, and mulching.

[0003] However, regarding the sugarcane seed planting stage, although some regions have achieved mechanized planting, its efficiency and error tolerance are still unsatisfactory. For example, the sugarcane automatic planting machine disclosed in patent CN202050673U includes a sugarcane seed planting device. The sugarcane seed planting device is set on the front and rear edges of the bottom of each of the four sugarcane seed boxes. It consists of left and right sprockets, chains on the sprockets, and planting actuation plates fixed on the chains. With this setting, the sugarcane seeds can be automatically dropped onto the chains and pushed outward by the planting actuation plates. However, due to the height difference between the chain and the ground, and because the transport is done from the upper side of the chain, the sugarcane seeds, falling from the upper layer of the chain as the chain rotates with the sprocket, may collide with the planting actuation plate or directly with the ground without restraint. This results in the seeds not falling accurately into the designated planting position; in some cases, the seeds may even be ejected from the planting furrow due to collisions with the planting actuation plate. Consequently, the entire planting structure cannot achieve accurate planting, leading to poor planting quality and directly affecting the growth of the sugarcane seeds. Furthermore, the automatic planting machine has a mulch film covering device at the rear of the machine, making it impossible to manually adjust the position of the sugarcane seeds later. Based on the applicant's participation in the Nanning Municipal Key Research and Development Program (Project No.: 20232053, Project Name: Research and Industrialization of Segmented Sugarcane Precision Planting Technology and Equipment), this project aims to solve the above problems and achieve mechanized sugarcane planting. Summary of the Invention

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this invention is to provide a sugarcane planting device that can realize automatic sugarcane seed dispensing and planting, and ensure the planting position.

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

[0006] A sugarcane planting device includes a vehicle body, a storage bin, a receiving and conveying device, a guide clamping device, and a pressing device. A drive mechanism is mounted on the vehicle body, enabling the vehicle body to move. The storage bin is mounted on the vehicle body, and a discharge port is provided at the bottom of the storage bin, allowing sugarcane seeds to be discharged one by one from the discharge port. The receiving and conveying device includes a pair of sprockets, a transmission chain, and several clamping mechanisms mounted on the transmission chain. The two sprockets are mounted on the vehicle body via shafts, and any one of the shafts is connected to an output end of the drive mechanism. The transmission chain is wound around the two sprockets, and at least a portion of the transmission chain is located directly below the discharge port. The clamping mechanism can receive and transport the sugarcane seeds discharged from the discharge port; the guide clamping device is installed on the vehicle body, and an expansion mechanism is provided at one end of the guide clamping device at the discharge port. The expansion mechanism can drive the clamping end of the clamping mechanism to open to receive the sugarcane seeds discharged from the discharge port; a tightening mechanism is provided outside the sprocket at the end of the guide clamping device away from the discharge port. The tightening mechanism can drive the clamping end of the clamping mechanism to clamp, so that the clamping mechanism can clamp the sugarcane seeds and rotate them to the lower side along with the transmission chain; a pressing device is installed on the vehicle body and is used to push the sugarcane seeds in the clamping mechanism delivered by the tightening mechanism downward out of the clamping mechanism.

[0007] Furthermore, the clamping mechanism includes a mounting base mounted on the transmission chain, a pair of clamping blocks slidably mounted on the mounting base, and a reset assembly disposed within the mounting base. The reset assembly connects the two clamping blocks and can be compressed or stretched. Both clamping blocks are located within the mounting base and have extension arms facing away from each other, with both extension arms extending out of the mounting base. Each of the two extension arms has a sliding head at its outward end, which can cooperate with the expansion mechanism and the tightening mechanism to drive the two clamping blocks to open away from each other or move closer together.

[0008] Furthermore, the reset assembly includes a reset spring and two connecting posts, one end of which can be movably inserted into one end of the other connecting post; the outward ends of the two connecting posts are respectively connected to the opposite sides of the two clamping blocks; the reset spring is movably fitted outside the area where the two connecting posts mate and its two ends are respectively fixedly connected to the outer walls of the two connecting posts.

[0009] Furthermore, the reset assembly includes a movable column and two drive columns. One end of each of the two drive columns is hinged to one end of the movable column, and the other end of each of the two drive columns is hinged to the two clamping blocks. The movable column moves through the fixed block in the mounting base. Adjusting nuts are provided at both ends of the movable column, and reset springs are fitted on the area of ​​the movable column between the two adjusting nuts and the corresponding side of the fixed block.

[0010] Furthermore, the expansion mechanism includes a main body block and guide blocks disposed on both sides of the main body block. The main body block is installed on the bottom of the vehicle body or storage bin in the area directly above the transmission chain. The two guide blocks are respectively disposed above both sides of the transmission chain. The two guide blocks are flared in shape, with the larger end located on both sides directly below the discharge port. Each of the two guide blocks has an inverted T-shaped guide groove along the transmission direction of the transmission chain on the opposite side. The sliding head can be engaged and slid within the inverted T-shaped guide groove.

[0011] Furthermore, the main body block is provided with a material discharge hole, and the main body block extends from the periphery of the material discharge hole to the lower end of the discharge port to form an installation ring platform. The installation ring platform is installed on the bottom of the storage bin. The material discharge hole and the material discharge hole are interconnected. Both guide blocks extend along the two ends of the main body block in the transmission direction of the transmission chain.

[0012] Furthermore, the tightening mechanism includes a semi-ring block and a mounting block disposed on the back of the semi-ring block. The mounting block is mounted on the vehicle body. The semi-ring block is coaxially disposed on the outside of the sprocket at the end away from the discharge port. The inner ring of the semi-ring block is provided with a receiving groove. When the clamping mechanism clamps the sugarcane seed and rotates with the sprocket, it will not contact the bottom of the receiving groove. Both sides of the receiving groove are provided with guide structures that cooperate with the sliding head. Both ends of the semi-ring block are provided with connecting sections extending outward on both sides of the receiving groove. The guide structure extends to the outward end of the connecting section. The distance between the guide structures on the two sets of connecting sections gradually decreases from the end to the end of the semi-ring block.

[0013] Furthermore, the pressing device is installed on the vehicle body in the corresponding area of ​​the discharge end of the tightening mechanism. The input end of the pressing device is connected to the rotating shaft near the side of the tightening mechanism. The rotating shaft can drive the pressing device to push the sugarcane seed in the clamping mechanism sent out by the tightening mechanism downward out of the clamping mechanism.

[0014] Furthermore, the pressing device includes a drive shaft, a cam mounted on the drive shaft, and a drive rod with one end eccentrically hinged to the cam. The drive shaft is rotatably mounted on the vehicle body and connected to the rotating shaft near the side of the tightening mechanism via a belt. A pressing block is slidably mounted on the vehicle body in the area in front of the discharge end of the tightening mechanism. One end of the pressing block is hinged to the other end of the drive rod. A resetting push block is movably inserted into the mounting base. The push block is located between the two clamping blocks. The pressing block can press the push block so that the push block presses the sugarcane seed between the two clamping blocks downward.

[0015] Furthermore, each of the two clamping blocks has an arc-shaped latch on its opposite side, and the arc-shaped latches on the two clamping blocks can cooperate with each other to form a clamping space for accommodating and restricting the sugarcane seed.

[0016] Furthermore, a pair of soil-opening guide wheels are provided at the front of the vehicle body, and a pair of soil-covering guide wheels are provided at the rear of the vehicle body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention provides an improved sugarcane planting device based on an existing vehicle body. It incorporates a receiving and conveying device that uses a transmission chain and sprockets to transport sugarcane seeds falling from the storage bin outwards. An openable clamping mechanism ensures accurate clamping of the seeds, preventing positional changes during sprocket transport that could affect subsequent planting. An expansion mechanism opens the clamping mechanism, allowing seeds falling from the discharge port to fall accurately into it. A tightening mechanism forces the clamping mechanism to hold the seeds, causing them to rotate downwards with the transmission chain. This effectively reduces the drop height of the seeds, improves their accuracy, and ensures planting quality. Furthermore, a pressing device is included. Compared to seeds falling naturally from the clamping mechanism, this device presses the seeds downwards after they leave the clamping mechanism, effectively ensuring a proper fall to the ground. This prevents seeds from colliding with the clamping mechanism or other objects due to their own weight, thus improving the accuracy of seed placement and guaranteeing planting quality. In addition, the pressing device is linked to the rotating shaft near the tightening mechanism, which reduces the overall control difficulty of the structure.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] See Figures 1 to 9 This application provides a sugarcane planting device, including a vehicle body 100, a storage bin 200, a receiving and conveying device 300, a guide clamping device 400, and a pressing device 500. A drive mechanism 110 is mounted on the vehicle body 100, enabling the vehicle body 100 to move. The storage bin 200 is mounted on the vehicle body 100, and a discharge port 210 is provided at the bottom of the storage bin 200, allowing sugarcane seeds in the storage bin 200 to be discharged one by one from the discharge port 210. The receiving and conveying device 300 includes a pair of sprockets 310, a transmission chain 320, and several clamping mechanisms 330 mounted on the transmission chain 320. The two sprockets 310 are mounted on the vehicle body 100 via a rotating shaft 340. Each rotating shaft 340 is connected to one output end of the drive mechanism 110. The transmission chain 320 is wound around the two sprockets 310, and at least a portion of the transmission chain 320 is located within... Directly below the discharge port 210, the clamping mechanism 330 can receive and transport the sugarcane seeds discharged from the discharge port 210; the guide clamping device 400 is installed on the vehicle body 100, and an expansion mechanism 410 is provided at one end of the guide clamping device 400 at the discharge port 210. The expansion mechanism 410 can drive the clamping end of the clamping mechanism 330 to open to receive the sugarcane seeds discharged from the discharge port 210; a tightening mechanism 420 is provided outside the sprocket 310 at the end of the guide clamping device 400 away from the discharge port 210. The tightening mechanism 420 can drive the clamping end of the clamping mechanism 330 to clamp, so that the clamping mechanism 330 can clamp the sugarcane seeds and rotate them to the lower side along with the transmission chain 320; a pressing device 500 is installed on the vehicle body 100 and is used to push the sugarcane seeds in the clamping mechanism 330 delivered by the tightening mechanism 420 downward out of the clamping mechanism 330.

[0037] In the above embodiments, the drive mechanism 110 can be either a conventional fuel engine or an electric motor, selected according to actual needs. In this application, a fuel engine is preferred for the drive mechanism 110, which can effectively improve its ease of use. Furthermore, in the above embodiments, the vehicle body 100 is equipped with wheels 140 at its bottom to enable self-propelled movement. Four sets of wheels are provided: two sets of front wheels and two sets of rear wheels. The drive mechanism 110 is connected to the main axle of the front wheels, primarily to facilitate the installation of the aforementioned receiving and clamping device 300, guide clamping device 400, and pressing device 500 on the rear of the vehicle body 100. In an improved embodiment, a driver's cab is also provided on the vehicle body 100 to facilitate control of the overall forward direction of the vehicle body 100.

[0038] It should be further noted that, in the above embodiments, to improve planting efficiency, multiple storage bins 200 are provided. Each storage bin 200 is equipped with a receiving and conveying device 300, a guide clamping device 400, and a pressing device 500. In this application, two sets are preferred, and their relatively small size makes them suitable for use in hilly areas. Furthermore, in the above embodiments, the drive mechanism 110 can be connected to any rotating shaft 340 via a belt. Of course, for ease of control, a clutch can also be connected between the drive mechanism 110 and the rotating shaft 340. This configuration allows for the disconnection of the drive to the receiving and conveying device 300 as needed, thereby stopping sowing. In the embodiments of this application, the pressing device 500 can be linked with the receiving and conveying device 300, or it can be driven by other external drive devices, such as telescopic poles or motors. Its power source can be obtained by the drive mechanism 110 driving a generator, which will not be detailed here.

[0039] This sugarcane planting equipment is an improvement on the existing vehicle body 100, featuring a receiving and conveying device 300. A transmission chain 320, in conjunction with a sprocket 310, transports sugarcane seeds falling from the storage bin 200 outwards. An openable clamping mechanism 330 ensures accurate clamping of the seeds, preventing positional changes during sprocket transport that could affect subsequent planting. An expansion mechanism 410 opens the clamping mechanism 330, allowing seeds falling from the discharge port 210 to fall accurately into it. A tightening mechanism 420 forces the clamping mechanism 330 to hold the seeds, causing them to rotate downwards along with the transmission chain 320. This effectively reduces the seed's fall height, improves its accuracy, and ensures planting quality. Furthermore, a pressing device 500 is designed. Compared to the natural falling of the sugarcane seed from the clamping mechanism 330, the pressing device 500 presses the sugarcane seed, which has left the clamping mechanism 330, downwards. This effectively ensures the seed falls precisely to the ground, preventing it from colliding with the clamping mechanism 330 or other objects due to its own weight and causing positional displacement. This significantly improves the accuracy of the seed's fall and guarantees planting quality. In addition, the pressing device 500 is linked to the rotating shaft 340 near the clamping mechanism 420, thus reducing the overall control complexity of the structure.

[0040] See Figure 1 In one embodiment of this application, to improve the automation level of the entire planting equipment and to achieve automatic soil opening and covering, a pair of soil opening guide wheels 120 are provided at the front of the vehicle body 100, and a pair of soil covering guide wheels 130 are provided at the rear of the vehicle body 100. The soil opening guide wheels 120 can be similar to figure-eight shaped guide blocks, automatically turning over and pushing the tilled soil to form planting ridges as the vehicle body 100 moves. In some embodiments, the soil opening guide wheels 120 can be driven by a drive mechanism 110, and their soil opening method can be similar to that of a tunneling wheel; these are common technical means, which will not be detailed here. Furthermore, the soil covering guide wheels 130 adopt a passive design, with both soil covering guide wheels 130 having a certain angle with the forward direction of the vehicle body 100, pushing the soil on both sides of the planting ridge onto the planting ridge. Generally, in conventional sugarcane planting, shallow soil covering is required in the early stages; therefore, the angles of the two soil covering guide wheels 130 can be adjusted to suit different soil covering conditions.

[0041] Of course, in some embodiments, a film covering mechanism 150 may be provided in front of the soil covering guide wheel 130 in the forward direction. The film covering mechanism 150 may be a conventional structure, such as the film covering device disclosed in a sugarcane planting machine in patent CN206165141U, which will not be described in detail here.

[0042] See Figures 2 to 3In one embodiment of this application, to better achieve individual sugarcane seed feeding, the storage bin 200 can adopt the sugarcane seed box design disclosed in the automatic sugarcane planter of patent publication number CN202050673U. However, this application, combined with the design of the receiving and conveying device 300, presents an improved technical solution. The storage bin 200 has an overall bucket-shaped design with an inclined ramp inside. At the bottom, there is a conveying pipe 220 that can only accommodate one sugarcane seed at a time, and the discharge port 210 is located at the bottom of the conveying pipe 220. Furthermore, to loosen the sugarcane seeds within the storage bin 200, in one embodiment of this application, the storage bin 200 is equipped with a loosening mechanism. This loosening mechanism can be a conventional lever mechanism or a motor-driven pusher block; these are common structures and will not be described in detail here.

[0043] See Figure 2 and Figure 3 Furthermore, in the above embodiment, since the discharge port 210 is located above the transmission chain 320, the sugarcane seeds in the conveying pipe 220 will fall directly onto the transmission chain 320 due to their own weight. However, due to the presence of the clamping mechanism 330, after one clamping mechanism 330 has finished clamping a sugarcane seed, subsequent sugarcane seeds will continue to fall from the conveying pipe 220. If the top of the clamping mechanism 330 is used to restrict the remaining sugarcane seeds from falling, the moving clamping mechanism 330 will scrape the sugarcane seeds that have not fallen. Therefore, in one embodiment of this application, the bottom of the conveying pipe 220 is hinged with two blocks 230 on both outer walls along its cross-sectional length and a drive rod 250 is slidably mounted thereon. One end of the block 230 can extend into the conveying pipe 220. The end of the drive rod 250 located outside the conveying pipe 220 is connected to the outer wall of the conveying pipe 220 by a locking spring 270. The locking spring 270 can force the drive rod 250 to reset so that one end of the block 230 can extend into the conveying pipe 220. Movable blocks 240 are hinged to the ends of the two blocks 230 located outside the conveying pipe 220. The upper end of the drive rod 250 is hinged to one end of the movable block 240. A roller 260 is rotatably mounted on the lower end of the drive rod 250. The roller 260 can abut against the top of the clamping mechanism 330. The clamping mechanism 330 can drive the block 230 to swing out of the conveying pipe 220 through the drive rod 250.

[0044] In the above embodiment, since there is a gap between two adjacent clamping mechanisms 330, when no clamping mechanism 330 pushes the driving rod 250, the two stops 230 will automatically swing and extend into the conveying pipe 220 due to the action of the locking spring 270. The extended part can then hold the sugarcane seed falling into the conveying pipe 220. Through the above design, automatic feeding of each sugarcane seed can be achieved to the greatest extent. It should be noted that the clamping mechanism 330 needs to be designed with a corresponding structure to cooperate with the roller 260 so that only one sugarcane seed falls through each clamping mechanism 330. At this time, the clamping mechanism 330 opened by the expansion mechanism 410 is located directly below the discharge port 210 and receives the sugarcane seed. Therefore, in actual use, when the clamping mechanism 330 moves with the transmission chain 320, the time it engages with the roller 260 is just enough to allow a sugarcane seed to fall from the conveying pipe 220 into the opened clamping mechanism 330; after the clamping mechanism 330 stops interacting with the roller 260, the two stops 230 will automatically swing and extend into the conveying pipe 220 due to the action of the locking spring 270. At this time, the extended part can lock the sugarcane seed that has fallen into the conveying pipe 220.

[0045] In an improved embodiment, the clamping mechanism 330 has a boss 33c on its top, which engages with the roller 260 and lifts the drive rod 250. Both ends of the boss 33c are provided with ramps to facilitate engagement with the roller 260.

[0046] See further Figures 2 to 6 To enable the clamping mechanism 330 to possess the aforementioned functions, in one embodiment of this application, the clamping mechanism 330 includes a mounting base 331 mounted on the transmission chain 320, a pair of clamping blocks 332 slidably mounted on the mounting base 331, and a reset assembly disposed within the mounting base 331. The reset assembly connects the two clamping blocks 332 and can be compressed or stretched. Both clamping blocks 332, located within the mounting base 331, have extension arms 333 facing away from each other, extending beyond the mounting base 331. Each of the outward-facing ends of the two extension arms 333 is provided with a sliding head 334. The sliding head 334 can cooperate with the expansion mechanism 410 and the tightening mechanism 420 to drive the two clamping blocks 332 to open away from each other or move closer together. The design of the sliding head 334 can actually be considered as a locking mechanism, which, in cooperation with the expansion mechanism 410 and the tightening mechanism 420, achieves different functions. In this embodiment, the mounting base 331 is provided with a sliding groove or slide rail, and two clamping blocks 332 are slidably mounted on the sliding groove or slide rail.

[0047] More specifically, the main function of the expansion mechanism 410 is to move the two clamping blocks 332 in opposite directions using the sliding head 334. This demonstrates that the expansion mechanism 410 and the sliding head 334 work together to pull the clamping block 332 on one side. Similarly, the tightening mechanism 420 and the sliding head 334 work together to press the clamping blocks 332 on the opposite side towards each other, bringing the two clamping blocks 332 closer together. To achieve these functions, the expansion mechanism 410 can be a guide groove structure or a magnetic adsorption structure, while the tightening mechanism 420 can be a limiting structure, such as a sliding groove structure, using the two sides of the sliding groove structure to restrict the movement of the two sliding heads 334. Furthermore, in the above embodiment, the main function of the reset component is to reset the two clamping blocks 332 to accommodate the movements of the expansion mechanism 410 and the tightening mechanism 420.

[0048] Furthermore, since sugarcane seeds typically retain 2-3 buds, their length is generally around 15-30 cm. Because the drive chain 320 needs to rotate around the sprocket 310, each link is relatively short, while the mounting base 331 and its two clamping blocks 332 are relatively long, depending on the length of the sugarcane seed. Therefore, in this application, the mounting base 331 and the drive chain 320 are hinged, ensuring that the mounting base 331's length does not interfere with the engagement between the drive chain 320 and the sprocket 310. Additionally, to prevent the mounting base 331 from wobbling as it rotates around the sprocket 310 with the drive chain 320, in an improved embodiment, the mounting base 331 is connected to the drive chain 320 at both ends in the drive direction via tension springs. This design utilizes the spring force to counteract the wobbling caused by the mounting base 331's own weight, ensuring the mounting base 331 remains stable as it rotates around the sprocket 310 with the drive chain 320.

[0049] See Figure 4In one embodiment, to simplify the above design and to achieve the reset action of the two clamping blocks 332, the reset assembly includes a reset spring 335 and two connecting posts 336. One end of one connecting post 336 can be movably inserted into one end of the other connecting post 336. The outward ends of the two connecting posts 336 are respectively connected to the opposite sides of the two clamping blocks 332. The reset spring 335 is movably fitted outside the area where the two connecting posts 336 meet, and its two ends are respectively fixedly connected to the outer walls of the two connecting posts 336. This design allows the two connecting posts 336 and the two clamping blocks 332 to be arranged in a straight line, resulting in a simpler structure. It should be noted that in this embodiment, when the two clamping blocks 332 are pulled in opposite directions by the expansion mechanism 410, the length of the reset spring 335 increases, and the two connecting posts 336 move outward in the axial direction. Similarly, when the two clamping blocks 332 are pushed and squeezed towards each other by the tightening mechanism 420, the return spring 335 is compressed, and at the same time, the two connecting posts 336 move towards each other in the axial direction. In addition, the interlocking design of the two connecting posts 336 can effectively limit the deformation direction of the return spring 335 to a certain extent, ensuring that the movement of the two clamping blocks 332 will not cause the return spring 335 to be fully deformed.

[0050] In the above embodiments, although the reset component has a simple structure, it is installed between two clamping blocks 332. The distance between the two clamping blocks 332 is generally only enough to accommodate one sugarcane seed container, resulting in a small installation space and high spatial requirements. See [reference needed] for further details. Figure 5 In an improved embodiment of this application, an embodiment is provided that can effectively solve the aforementioned installation space problem. The reset assembly includes a movable column 337 and two drive columns 338. One end of each drive column 338 is hinged to one end of the movable column 337, and the other end of each drive column 338 is hinged to two clamping blocks 332. The movable column 337 movably passes through a fixed block within the mounting base 331. Adjusting nuts 339 are provided at both ends of the movable column 337, and a reset spring 33a is fitted onto the area of ​​the movable column 337 between the two adjusting nuts 339 and the corresponding side of the fixed block. The movable column 337 and the two drive columns 338 are arranged in a Y-shape, and this offset arrangement provides sufficient space for installation. The return springs 33a on both sides of the fixed block are for returning to their original positions under tension and compression conditions, respectively. The tightness of the return springs 33a can be effectively adjusted using the adjusting nut 339, making them suitable for different working conditions.

[0051] See further Figures 2 to 4To achieve the open state of the clamping mechanism 330, in one embodiment of this application, the expansion mechanism 410 includes a main body block 411 and guide blocks 412 disposed on both sides of the main body block 411. The main body block 411 is installed on the bottom of the vehicle body 100 or the storage bin 200 in the area directly above the transmission chain 320. The two guide blocks 412 are respectively disposed above the two sides of the transmission chain 320, and the two guide blocks 412 are flared, with the larger end located on both sides directly below the discharge port 210. On the opposite side of each of the two guide blocks 412, an inverted T-shaped guide groove 413 is provided along the transmission direction of the transmission chain 320, and the sliding head 334 can be engaged and slid within the inverted T-shaped guide groove 413. In practice, the two guide blocks 412 and the main body block 411 form an I-shaped structure, but in actual installation, a clearance structure is needed between the two guide blocks 412 to facilitate the falling of the sugarcane seed. Furthermore, in the above embodiment, since the two guide blocks 412 are arranged in a trumpet shape with their larger ends located on both sides directly below the discharge port 210, the two sliding heads 334 can respectively engage with the inverted T-shaped guide grooves 413 on the corresponding sides when the clamping mechanism 330 moves with the transmission chain 320. As the clamping mechanism 330 continues to move with the transmission chain 320, the guiding design and limiting effect of the inverted T-shaped guide grooves 413 cause the two clamping blocks 332 to be pulled outwards, thereby widening the distance between the two clamping blocks 332 and opening the entire clamping mechanism 330. In this state, it is beneficial for the sugarcane seeds discharged from the discharge port 210 to fall into the clamping space between the two clamping blocks 332. After the clamping mechanism 330 continues to move with the transmission chain 320 and leaves the guide block 412, due to the removal of the constraint of the inverted T-shaped guide groove 413 and the resetting action of the resetting component, the two clamping blocks 332 cooperate to clamp the sugarcane seed or move closer to each other to reduce the distance between them. It should be noted that, due to the difference in the diameter of the sugarcane seed, the two clamping blocks 332 may directly clamp the sugarcane seed or may not be able to clamp it after moving with the transmission chain 320 and leaving the guide block 412. Therefore, this application designs a tightening mechanism 420, which enables the two clamping blocks 332 to clamp sugarcane seeds of different diameters, thus providing strong adaptability.

[0052] Of course, in some embodiments, the opening degree of the two clamping blocks 332 needs to be fully adaptable to all diameter types of sugarcane seeds under normal circumstances. In this case, the distance between the two clamping blocks 332 is large enough that the sugarcane seeds can fall from the discharge port 210 into the two clamping blocks 332 without obstruction, even without the expansion mechanism 410. However, since there is no restriction between the two ends of the two clamping blocks 332 on the same clamping mechanism 330, and the vehicle body 100 will inevitably experience bumps during travel, the sugarcane seeds are prone to falling out of the two clamping blocks 332 and may get stuck on the transmission chain 320. To address this situation, in the above embodiments, limiting guard plates can be provided on both sides of the transmission chain 320. The limiting guard plates can effectively prevent the sugarcane seeds from sliding outward from between the clamping blocks 332 and affecting the normal operation of the transmission chain 320. Of course, in actual operation, the spacing between the two clamping blocks 332 needs to be adapted to all types and specifications of sugarcane seeds. Also, there will be some deviation during the falling process. Therefore, the clamping mechanism 330 needs to be made large enough, and the transmission chain 320 must also be adapted to the size of the clamping mechanism 330. This requires combining multiple single chains available on the market, and also adapting the sprocket 310. Therefore, these modifications make replacing the transmission chain 320 later very troublesome. Furthermore, increasing the structural size results in a larger footprint. The corresponding tightening mechanism 420 and its supporting structures, adapted to the size of the sprocket 310, also need to be enlarged accordingly, thus increasing equipment costs. In addition, since the planting spacing between different rows of sugarcane seeds is generally 50-70 cm, increasing the structural size may affect the final planting spacing. In conclusion, this application prefers to use the expansion mechanism 410 to open the clamping blocks 322. It should be noted that, because the transmission chain 320 will shake up and down due to the bumps of the vehicle body 100 during operation, the sugarcane seed is prone to shaking during the conveying process described by the clamping mechanism 330. Therefore, under normal circumstances, if the two clamping blocks 332 are opened too large, the transport quality of the sugarcane seed will be poor, and the subsequent tightening mechanism 420 will not be able to cooperate with it for precise clamping.

[0053] In some implementations, to address the issue of sugarcane seeds easily falling between the two clamping blocks 332, each of the two clamping blocks 332 has an arc-shaped latch on its opposite side. These arc-shaped latches on the two clamping blocks 332 can cooperate to form a clamping space for accommodating and restricting the sugarcane seeds. This prevents the sugarcane seeds from slipping from both ends of the two clamping blocks 332 within the clamping space, ensuring effective transportation.

[0054] In the above-mentioned improved design, during actual use, the transmission chain 320 will inevitably sway up and down during operation. Therefore, sufficient space needs to be left between the discharge port 210 and the top of the clamping mechanism 330. However, the existence of this space causes the sugarcane seed to collide with the swaying clamping mechanism 330 during the falling process. As a result, the sugarcane seed may get stuck in the aforementioned space or be bounced away by the swaying clamping mechanism 330.

[0055] See you again Figure 2 , Figure 3 , Figure 4 and Figure 7 To ensure that the material falling into the discharge port 210 is safe, a discharge hole 414 is provided on the main body block 411. The main body block 411 extends from the periphery of the discharge hole 414 towards the lower end of the discharge port 210 to form an mounting ring platform. The mounting ring platform is installed on the bottom of the storage bin 200. The discharge holes 414 are interconnected. Both guide blocks 412 extend along the main body block 411 at both ends in the transmission direction of the transmission chain 320. In fact, in this application, the mounting ring platform is connected to the aforementioned conveying pipe 220.

[0056] See further Figure 1 and Figure 9In order for the two clamping blocks 332 to clamp the sugarcane seed between them and to rotate 180° with the sprocket 310 without falling off, in one embodiment of this application, the tightening mechanism 420 includes a semi-ring block 421 and a mounting block 422 disposed on the back of the semi-ring block 421. The mounting block 422 is mounted on the vehicle body 100. The semi-ring block 421 is coaxially disposed on the outside of the sprocket 310 at the end away from the discharge port 210. The inner ring of the semi-ring block 421 is provided with a receiving groove 423. The clamping mechanism 330 clamps... When the sugarcane seed is held and rotates with the sprocket 310, it will not contact the bottom of the receiving groove 423. Both sides of the receiving groove 423 are provided with guide structures 424 that cooperate with the sliding head 334. Both ends of the semi-ring block 421 are provided with outward-facing connecting sections 425 on both sides of the receiving groove 423. The guide structures 424 extend to the outward-facing end of the connecting sections 425. The distance between the guide structures 424 on the two sets of connecting sections 425 gradually decreases from one end towards the other end of the semi-ring block 421. In this embodiment, the structural constraint of the receiving groove 423 forces the two sliding heads 334 to bring the two clamping blocks 332 closer together, thereby clamping the sugarcane seed tightly. At this time, the two clamping blocks 332 will not cause the sugarcane seed to fall even when it rotates 180° with the sprocket 310. The design of the connecting segment 425 extends the distance between the two ends of the semi-ring block 421 to a certain extent, so that the connecting segment 425 and the semi-ring block 421 form a C-shaped structure. In one embodiment of this application, two semi-ring blocks 421 are provided and connected by a mounting block 422. The gap between the two semi-ring blocks 421 forms the aforementioned receiving groove 423, and this design is easier to process.

[0057] It should be noted that in the above embodiments, since sugarcane seeds generally retain 2-3 buds, their length is generally around 15-30cm. As the sugarcane seed rotates around the sprocket 310 following the two clamping blocks 332, its ends require a large amount of space for movement. Therefore, the receiving groove 423 in this application is relatively deep to avoid motion interference between the sugarcane seed and the bottom of the receiving groove 423. In the above embodiments, the guide structure 424 is actually a groove, which directly abuts against the outward end of the sliding head 334 to achieve the above function. Furthermore, the design of the spacing between the guide structures 424 on the connecting section 425 gradually decreasing from one end to the other end of the semi-ring block 421 is mainly to make the spacing between the two guide structures 424 larger at both ends and relatively smaller in the middle. This allows the smaller area to force the two clamping blocks 332 to clamp the sugarcane seed; the larger ends can accommodate the distance between the two sliding heads 334 in their natural state.

[0058] See Figures 8 to 9After the two clamping blocks 332 emerge from the lower end of the semi-ring block 421, due to the lack of restraint from the guide structure 424, the two clamping blocks 332 move back to their original positions under the action of the reset component. At this time, the two clamping blocks 332 will gradually release the sugarcane seed they are holding, and the sugarcane seed will fall downwards under its own weight. In this application, in order to reduce the falling height of the sugarcane seed, the lower end of the semi-ring block 421 is 10-20cm away from the ground, which can effectively ensure the accuracy of the falling position of the sugarcane seed and avoid the collision between the soil clods on the ground and the lower end of the semi-ring block 421, thus affecting the movement of the clamping blocks 332. To ensure that the sugarcane seed exiting from the lower end of the semi-ring block 421 between the two clamping blocks 332 falls neatly, in one embodiment of this application, a pressing device 500 is installed on the vehicle body 100 in the corresponding area at the discharge end of the tightening mechanism 420. The input end of the pressing device 500 is connected to the rotating shaft 340 near the side of the tightening mechanism 420. The rotating shaft 340 can drive the pressing device 500 to push the sugarcane seed delivered by the tightening mechanism 420 downward out of the clamping mechanism 330. In this application, the pressing device 500 can be a conventional cylinder or a telescopic mechanism, as long as it can reciprocate and press the sugarcane seed.

[0059] See Figure 8 and Figure 9 In order to enable the pressing device 500 to automatically press the sugarcane seed between the two clamping blocks 332 downwards following the rotation of the sprocket 310, in one embodiment of this application, the pressing device 500 includes a drive shaft 510, a cam 520 disposed on the drive shaft 510, and a drive rod 530 with one end eccentrically hinged to the cam 520. The drive shaft 510 is rotatably mounted on the vehicle body 100 and connected to the rotating shaft 340 near the side of the tightening mechanism 420 via a belt. A pressing block 540 is slidably mounted on the vehicle body 100 in the area in front of the discharge end of the tightening mechanism 420. One end of the pressing block 540 is hinged to the other end of the drive rod 530. A resetting pushing block 33b is movably inserted into the mounting base 331. The pushing block 33b is located between the two clamping blocks 332. The pressing block 540 can press the pushing block 33b so that the pushing block 33b presses the sugarcane seed between the two clamping blocks 332 downward.

[0060] See Figure 8 In the above embodiment, the mounting base 331 is provided with a movable groove 33d, and the push block 33b is slidably installed in the movable groove 33d. The back of the push block 33b is connected to the mounting base 331 through a top pressure spring 33e, which is used to reset the push block 33b.

[0061] Furthermore, it is important to note the connection between the drive shaft 510 and the rotating shaft 340 near the tightening mechanism 420. Each rotation of the drive shaft 510 corresponds to one mounting seat 331 emerging from the lower end of the semi-ring block 421. That is, the circumference of the drive shaft 510 is equal to the distance between the two mounting seats 331 on the transmission chain 320. This design ensures that each rotation of the drive shaft 510 presses against a push block 33b on one mounting seat 331. The structural design described above in this application can be implemented according to these requirements. In an improved embodiment, to adjust the above design requirements, a transmission wheel can be designed on the rotating shaft 340, connected to the drive shaft 510 via a belt. This design ensures the normal operation of the pressing block 540.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
