Description

Technical Field

[0001] This invention relates to the field of plant processing equipment technology, and more specifically, to a flattening device suitable for stalk-shaped plants. Background Technology

[0002] Stem-like plants, such as reeds, are tall grasses with a wide distribution and high economic and ecological value. They are often used as sand barrier materials, especially in the field of desertification control and soil stabilization. Because reed stalks are thick and hollow, they usually need to be flattened first to facilitate subsequent storage, transportation, weaving, or pressing.

[0003] Currently, the flattening of reeds mainly relies on traditional manual methods, such as using stone rollers. The specific process of this method is as follows: the harvested reeds are laid on a flat ground, and a heavy stone roller is pulled back and forth by manpower or animal power to flatten the reeds.

[0004] However, this traditional stone roller compaction method has the following obvious drawbacks: First, the work efficiency is extremely low, relying entirely on human and animal power, making it difficult to achieve large-scale, continuous production, resulting in high labor intensity and low output. Second, the flattening quality is difficult to guarantee. Because the compaction pressure and path of the stone roller are difficult to control, the reeds are often crushed, broken, or even severely damaged in fiber. The flattened reeds are irregular in shape, seriously affecting subsequent bundling and use, and causing waste of raw materials. Summary of the Invention

[0005] The problem addressed by this invention is how to achieve efficient and high-quality flattening of large quantities of stalk-shaped plants, such as reeds.

[0006] To address the above problems, the present invention provides a flattening device suitable for stalk-shaped plants, comprising: frame; The first conveying assembly is installed at the upper part of one end of the frame and is used to convey the rod-shaped plant to be flattened; A flattening mechanism is provided on one side of the tail end of the first conveying assembly and is used to flatten the rod-shaped plant conveyed by the first conveying assembly. The second conveying assembly is installed on the upper part of the other end of the frame, and the second conveying assembly is located on the side of the flattening mechanism away from the first conveying assembly, for receiving and conveying the flattened rod-shaped plants; A flipping mechanism, disposed on the side of the second conveying assembly, has a working state and a reset state; wherein, in the working state, the flipping mechanism flips upward to unload the flattened rod-shaped plant from the upper part of the second conveying assembly; in the reset state, the flipping mechanism resets to allow the flattened rod-shaped plant to pass over the upper part of the second conveying assembly.

[0007] Optionally, the flattening mechanism includes a roller pressing assembly and two sliding frames, the two sliding frames being installed at a distance from each other on the frame along the width direction of the first conveying assembly and forming an installation space between them; the roller pressing assembly includes a first pressure roller and a second pressure roller, the first pressure roller being above the second pressure roller and both being installed within the installation space, a flattening interval for flattening the rod-shaped plant being formed between the first pressure roller and the second pressure roller, and the first pressure roller being movably connected to the two sliding frames relative to the second pressure roller.

[0008] Optionally, the flattening mechanism further includes two pressure adjusting components. The top ends of the two pressure adjusting components are respectively connected to the corresponding two sliding frames, and the bottom ends of the two pressure adjusting components are respectively connected to the two axial ends of the first pressure roller. The pressure adjusting components are used to adjust the height of the first pressure roller to adjust the flattening interval between the first pressure roller and the second pressure roller.

[0009] Optionally, the pressure regulating assembly includes a rod-shaped adjusting member, a sliding plate, an elastic connector, and a bearing seat. The axial end of the first pressure roller is embedded in the bearing seat. The sliding plate and the elastic connector are disposed above the bearing seat. The top and bottom ends of the elastic connector are respectively connected to the sliding plate and the bearing seat. The top and bottom ends of the rod-shaped adjusting member are respectively connected to the top plate of the sliding frame and the sliding plate. The rod-shaped adjusting member is used to rotate around its own axis to drive the sliding plate to move up and down.

[0010] Optionally, at least one of the sliding plate and the bearing housing is slidably connected to the sliding frame.

[0011] Optionally, the first conveying assembly includes a belt and a plurality of drive rollers, the plurality of drive rollers being spaced apart along the length of the first conveying assembly and mounted on the frame, and the plurality of drive rollers being connected by the belt.

[0012] Optionally, the second conveying assembly includes a plurality of support rollers spaced apart, the plurality of support rollers being spaced apart and mounted on the upper part of the other end of the frame, the support rollers being used to receive and convey the flattened rod-shaped plants.

[0013] Optionally, the flipping mechanism includes a first driving device, a linkage assembly, a first rod, and a plurality of second rods. The plurality of second rods are alternately distributed with the plurality of support rollers. The plurality of second rods are respectively connected to the first rods. The first rods are rotatably connected to the frame, and their rotation axis is consistent with the conveying direction of the second conveying assembly. The two ends of the linkage assembly are respectively connected to the first driving device and the first rods, and are used to drive the first rods and the plurality of second rods to rotate under the drive of the first driving device, so that the second rods switch between the working state and the reset state.

[0014] Optionally, the connecting rod assembly includes a crank, a connecting rod, and a sway bar; the first driving device is connected to one end of the crank for driving the crank to rotate, the two ends of the connecting rod are respectively rotatably connected to the other end of the crank and one end of the sway bar, the other end of the sway bar is fixedly connected to the first rod, and the sway bar is used to drive the first rod and the second rod to rotate relative to the frame.

[0015] Optionally, the flattening device for stalk-shaped plants further includes a second drive mechanism and a chain drive system. The second drive mechanism is drivenly connected to the chain drive system, and the drive roller, the support roller, and the roller pressing assembly are respectively drivenly connected to the chain drive system for simultaneous operation under the drive of the chain drive system.

[0016] The beneficial effects of the flattening device for stalk-shaped plants of the present invention are: During operation, the first conveying component automatically and continuously feeds the stalk-shaped plants (such as reeds) to be flattened smoothly into the flattening mechanism behind it. This replaces the manual feeding in the traditional process, greatly reducing human intervention. On the other hand, the flattening mechanism can be mechanically driven, and its working pressure and movement trajectory are pre-designed and stable and controllable. It can apply a uniform and consistent flattening force to each continuously input stalk-shaped plant. The synergy between the two realizes the automated cycle of "continuous feeding-stable flattening". This solves the problem of low efficiency caused by the interruption of manual feeding in the traditional method, and also solves the problem of uneven flattening quality and easy crushing and breakage caused by the uncontrollable pressure of the stone roller. It provides neat and uniform flattened stalk-shaped plants for subsequent processes.

[0017] The flattened stem-shaped plants are then received by the second conveying component and continue to be transported forward in an orderly manner, avoiding the secondary mess caused by the flattened stem-shaped plants scattering on the ground and requiring manual collection and sorting in the traditional process. When a certain amount of stem-shaped plants accumulates on the second conveying component, the flipping mechanism switches to working mode, flips upward, and neatly unloads the batch of flattened stem-shaped plants from the second conveying component, piling them in a predetermined position; after unloading is completed, the flipping mechanism automatically switches to the reset state, allowing subsequent stem-shaped plants to continue to pass through.

[0018] By integrating the first conveying component, flattening mechanism, second conveying component, and tilting mechanism into a single frame, a complete and independent rod-pressing operation platform is constructed. The "convey-unload-reset" cycle formed by the second conveying component and tilting mechanism enables the automatic collection and neat stacking of flattened rod-shaped plants. This perfectly replaces the arduous manual labor of picking up and arranging reeds from the ground in traditional processes. This not only further improves overall operational efficiency but, more importantly, maintains the regular shape of the flattened rod-shaped plants to the maximum extent through orderly conveying and neat unloading. This completely solves the persistent problem of "messy after pressing, even messier after collection" in traditional processes, ensuring the quality of the final product (rod-shaped plants) and reducing raw material waste.

[0025] like Figure 1 As shown in the figure, an embodiment of the present invention provides a flattening device suitable for stalk-shaped plants, comprising: 100 racks; The first conveying assembly 200 is installed on the upper part of one end of the frame 100 and is used to convey the rod-shaped plant to be flattened. A flattening mechanism 300 is disposed on one side of the tail end of the first conveying component 200 and is used to flatten the rod-shaped plant conveyed by the first conveying component 200. The second conveying assembly 400 is installed on the upper part of the other end of the frame 100, and the second conveying assembly 400 is located on the side of the flattening mechanism 300 away from the first conveying assembly 200, for receiving and conveying the flattened rod-shaped plants. A flipping mechanism 500 is disposed on the side of the second conveying assembly 400 and has a working state and a reset state; wherein, in the working state, the flipping mechanism 500 flips upward to unload the flattened rod-shaped plant from the upper part of the second conveying assembly 400; in the reset state, the flipping mechanism 500 resets to allow the flattened rod-shaped plant to pass over the upper part of the second conveying assembly 400.

[0026] Specifically, the frame 100 is the load-bearing skeleton of the entire equipment, and is typically made of metal profiles, such as square steel, channel steel, angle steel, or I-beams, and is fixedly connected by welding, bolting, or riveting. The frame 100 is designed as a frame structure with sufficient structural strength and rigidity to ensure that it remains stable and does not deform when bearing the weight of various functional components (such as the conveying assembly, flattening mechanism 300, and tilting mechanism 500) as well as the vibrations and loads generated during operation.

[0027] A first conveying assembly 200 is installed at the upper rear end of the frame 100. This first conveying assembly 200 is used to receive and flatten loose or bundled stalk-shaped plants (reeds) and continuously and smoothly convey them forward to the flattening mechanism 300. The first conveying assembly 200 can be a belt conveyor 210, a chain conveyor, a roller conveyor, or other conveying devices with continuous conveying capabilities.

[0028] On one side of the tail end of the first conveying component 200, the flattening mechanism 300 is used to apply a controllable and uniform extrusion force to the rod-shaped plant (reed) continuously input by the first conveying component 200, so that its stem is cracked and flattened, destroying its original hollow structure.

[0029] On the side of the flattening mechanism 300 away from the first conveying assembly 200, i.e., in front of the flattening mechanism 300, a second conveying assembly 400 is installed on the upper part of the other end of the frame 100. This second conveying assembly 400 receives the flattened, rod-shaped plants output from the flattening mechanism 300 and continues to convey them forward for subsequent collection or bundling operations. The second conveying assembly 400 can also be a belt conveyor 210 or a chain conveyor.

[0030] A flipping mechanism 500 is provided on the side (e.g., left or right) of the second conveying assembly 400. The flipping mechanism 500 has a working state and a reset state, and is used to neatly unload the flattened rod-shaped plants from the second conveying assembly 400 to achieve automatic stacking, so as to facilitate subsequent manual or mechanical bundling.

[0031] Stem plants include, but are not limited to, reeds, and may also include other stem crops that require flattening.

[0032] In this embodiment, during operation, the first conveying component 200 automatically and continuously feeds the rod-shaped plants (such as reeds) to be flattened smoothly into the flattening mechanism 300. This replaces the manual feeding in the traditional process, greatly reducing manual intervention. On the other hand, the flattening mechanism 300 can be mechanically driven, and its working pressure and movement trajectory are pre-designed and stable and controllable. It can apply a uniform and consistent flattening force to each continuously input rod-shaped plant. The synergy between the two realizes the automated cycle of "continuous feeding-stable flattening", which not only solves the problem of low efficiency caused by the interruption of manual feeding in the traditional method, but also solves the problem of uneven flattening quality and easy crushing and breakage caused by the uncontrollable pressure of the stone roller. It provides neat and uniform flattened rod-shaped plants for subsequent processes.

[0033] The flattened stem-shaped plants are then received by the second conveying component 400 and continue to be conveyed forward in an orderly manner, avoiding the secondary mess caused by the flattened stem-shaped plants scattering on the ground and requiring manual collection and sorting in the traditional process. When a certain amount of stem-shaped plants accumulates on the second conveying component 400, the flipping mechanism 500 switches to the working state, flips upward, and neatly unloads the batch of flattened stem-shaped plants from the second conveying component 400, piling them in a predetermined position; after unloading is completed, the flipping mechanism 500 automatically switches to the reset state, allowing subsequent stem-shaped plants to continue to pass through.

[0034] By setting up a frame 100, the first conveying component 200, the flattening mechanism 300, the second conveying component 400, and the flipping mechanism 500 are all integrated into one unit, constructing a complete and independent rod-pressing operation platform. The "convey-unload-reset" cyclic action formed by the second conveying component 400 and the flipping mechanism 500 achieves automatic collection and neat stacking of the flattened rod-shaped plants, perfectly replacing the heavy labor of manually lifting and arranging reeds from the ground in the traditional process. This not only further improves the overall operational efficiency, but more importantly, through orderly conveying and neat unloading, it maximizes the maintenance of the regular shape of the flattened rod-shaped plants, completely solving the persistent problem of "messy after pressing, even messier after collection" in the traditional process, ensuring the quality of the final product (rod-shaped plants), and reducing raw material waste.

[0035] Optionally, combined Figure 2 As shown, the flattening mechanism 300 includes a roller pressing assembly and two sliding frames 310. The two sliding frames 310 are installed at intervals along the width direction of the first conveying assembly 200 on the frame 100, and an installation space is formed between them. The roller pressing assembly includes a first pressure roller 320 and a second pressure roller 330. The first pressure roller 320 is located above the second pressure roller 330, and both are installed in the installation space. A flattening interval for flattening the rod-shaped plant is formed between the first pressure roller 320 and the second pressure roller 330. The first pressure roller 320 is connected to the two sliding frames 310 for vertical movement relative to the second pressure roller 330.

[0036] Specifically, the width direction of the first conveying component 200 can be parallel to... Figure 2 The X-axis direction is parallel to the coordinate system; the length direction of the first conveying component 200 can be parallel to... Figure 2 The Y-axis is parallel in the coordinate system.

[0037] Two sliding frames 310 are mounted opposite each other and spaced apart on the frame 100 along the width direction of the first conveying assembly 200, forming an installation space between them for accommodating the roller pressing assembly. The sliding frames 310 can be fixed to the frame 100 by bolts or welding to ensure their stability.

[0038] The first pressure roller 320 is located above the second pressure roller 330. The two are arranged in parallel and are installed in the installation space between the two sliding frames 310. The axial ends of the first pressure roller 320 (second pressure roller 330) are connected to the corresponding two sliding frames 310.

[0039] A flattening interval is formed between the first pressure roller 320 and the second pressure roller 330 for flattening the stalk-shaped plant. The initial size of this flattening interval can be preset according to the average diameter of the stalk-shaped plant to be flattened. Since the first pressure roller 320 can move up and down, when stalk-shaped plants of different thicknesses pass through the flattening interval, the first pressure roller 320 can automatically adapt to the diameter changes of the stalk-shaped plants, ensuring the smooth progress of the flattening process.

[0040] In this optional embodiment, by setting two opposing sliding frames 310, stable support and precise installation positions are provided for the first pressure roller 320 and the second pressure roller 330, ensuring that the first pressure roller 320 and the second pressure roller 330 always remain parallel and centered, thereby guaranteeing the stability of the flattening process and the regularity of the rod-shaped plant morphology after flattening. At the same time, the sliding frames 310 provide a guiding basis for subsequent pressure adjustment and vertical movement.

[0041] By using a first pressure roller 320 and a second pressure roller 330 that are parallel to each other and spaced apart, continuous rolling compression of the stalk-shaped plant is achieved, replacing the intermittent and repeated rolling of a stone roller and significantly improving flattening efficiency. At the same time, because the flattening interval between the first pressure roller 320 and the second pressure roller 330 is fixed (or adjustable), the pressure on the stalk-shaped plant is uniform as it passes through, effectively avoiding the problems of uneven pressure causing crushing and breakage in traditional rolling, thus ensuring flattening quality.

[0042] By allowing the first pressure roller 320 to move up and down relative to the second pressure roller 330, the flattening mechanism 300 can adapt to stalk-shaped plants of different thicknesses. This feature significantly improves the versatility and adaptability of the equipment, enabling it to process raw materials of varying thicknesses and ensuring the flattening effect of stalk-shaped plants of various specifications.

[0043] Optionally, combined Figure 2 As shown, the flattening mechanism 300 further includes two pressure adjusting components 340. The top ends of the two pressure adjusting components 340 are respectively connected to the corresponding two sliding frames 310, and the bottom ends of the two pressure adjusting components 340 are respectively connected to the two axial ends of the first pressure roller 320. The pressure adjusting components 340 are used to adjust the height of the first pressure roller 320 to adjust the flattening interval between the first pressure roller 320 and the second pressure roller 330.

[0044] Specifically, the pressure regulating component 340 can be a bolt regulating component, or it can be a hydraulic cylinder or a pneumatic cylinder that directly drives the first pressure roller 320 to move up and down. By controlling the hydraulic or pneumatic pressure, the pressure can be adjusted, and the function of adjusting the flattening interval can also be realized.

[0045] In this optional embodiment, by setting two independent pressure regulating components 340, the pressure at both ends of the first pressure roller 320 can be controlled separately and independently. This structure allows the operator to independently adjust the pressure at both ends of the first pressure roller 320 as needed, ensuring that the first pressure roller 320 remains horizontal along its entire length, thereby ensuring that the flattened rod-shaped plant has a uniform thickness in its width direction and avoiding the problem of inconsistent flattening quality caused by uneven pressure.

[0046] By adjusting the height of the first pressure roller 320, the flattening interval between the first pressure roller 320 and the second pressure roller 330 can be precisely controlled, thereby setting the optimal flattening parameters according to the characteristics of different rod-shaped plants (such as diameter, hardness, and moisture content), ensuring the optimal flattening effect.

[0047] For the same batch of raw materials, a fixed flattening interval can be set to ensure that all stalk plants passing through the equipment are subjected to the same flattening treatment, thereby ensuring the consistency of product quality.

[0048] For flattened plants used for different purposes (such as weaving, pressing boards, and mulching for desertification control), different degrees of flattening can be obtained by adjusting the flattening interval to meet diverse market demands.

[0049] Optionally, combined Figure 3 As shown, the pressure regulating assembly 340 includes a rod-shaped adjusting member 341, a sliding plate 342, an elastic connecting member 343, and a bearing seat 344. The axial end of the first pressure roller 320 is embedded in the bearing seat 344. The sliding plate 342 and the elastic connecting member 343 are disposed above the bearing seat 344. The top and bottom ends of the elastic connecting member 343 are respectively connected to the sliding plate 342 and the bearing seat 344. The top and bottom ends of the rod-shaped adjusting member 341 are respectively connected to the top plate of the sliding frame 310 and the sliding plate 342. The rod-shaped adjusting member 341 is used to rotate around its own axis to drive the sliding plate 342 to move up and down.

[0050] Specifically, the axial end of the first pressure roller 320 is rotatably embedded in a bearing housing 344 via a bearing. The bearing housing 344 is used to support the roller shaft of the first pressure roller 320, allowing it to rotate freely.

[0051] The elastic connector 343 is disposed between the bottom of the sliding plate 342 and the top of the bearing seat 344. In a preferred embodiment, the elastic connector 343 is a spring. The bottom end of the elastic connector 343 is connected to or abuts against the upper end of the bearing seat 344, and the top end of the elastic connector 343 is connected to or abuts against the lower surface of the sliding plate 342. The elastic connector 343 applies a downward elastic force to the bearing seat 344 and provides cushioning when the first pressure roller 320 is impacted.

[0052] Above the sliding plate 342, a rod-shaped adjusting member 341 is provided. In a preferred embodiment, the rod-shaped adjusting member 341 comprises an adjusting screw and an adjusting nut. A threaded hole is provided on the top plate of the sliding frame 310; the adjusting screw passes through this threaded hole and is threadedly connected to the adjusting nut for easy rotation by the operator. The lower end of the adjusting screw passes through the top plate and connects to the upper surface of the sliding plate 342. The rod-shaped adjusting member 341 is rotatable about its own axis.

[0053] As an optional connection method, the lower end of the adjusting screw can be rotatably connected to the sliding plate 342. For example, a groove is provided on the sliding plate 342, and the lower end of the adjusting screw is embedded in the groove and can rotate freely. In this way, when the adjusting screw is rotated, the adjusting screw only rotates relative to the sliding plate 342 and does not drive the sliding plate 342 to rotate. The sliding plate 342 only moves up and down.

[0054] When the flattening interval needs to be adjusted, the operator rotates the adjusting screw. Taking reducing the flattening interval (i.e., increasing the flattening force) as an example, the operator rotates the adjusting screw clockwise, moving it downwards. The lower end of the adjusting screw pushes the sliding plate 342 downwards, compressing the elastic connector 343 and increasing its compression. The downward elastic force of the elastic connector 343 on the bearing seat 344 increases accordingly. This force is transmitted to the first pressure roller 320 through the bearing seat 344, and under the weight of the first pressure roller 320, it presses more tightly against the second pressure roller 330, thereby reducing the flattening interval or increasing the flattening force on the passing stalk-shaped plant.

[0055] Conversely, when it is necessary to increase the flattening interval (i.e., reduce the flattening force), the operator rotates the adjusting screw counterclockwise, causing it to move upwards. The downward force exerted by the lower end of the adjusting screw on the sliding plate 342 decreases. Under the elastic force of the elastic connector 343, the sliding plate 342 and the bearing seat 344 will move upwards a certain distance until the elastic force of the elastic connector 343 reaches a new equilibrium with the weight of the first pressure roller 320 and the constraint of the adjusting screw. At this point, the compression of the elastic connector 343 decreases, the downward force on the bearing seat 344 decreases, and the first pressure roller 320 slightly descends under its own weight (but is supported by the spring force of the elastic connector 343), thereby increasing the initial gap between the first pressure roller 320 and the second pressure roller 330, i.e., increasing the flattening interval.

[0056] During equipment operation, when a rod-shaped plant with a suddenly increased diameter passes through the flattening gap, the first pressure roller 320 floats upward, causing the bearing seat 344 to compress the elastic connector 343 upward. The elastic connector 343 is further compressed, absorbing the impact energy and providing buffer protection. After the impact, the elastic connector 343 returns to its original shape, pushing the first pressure roller 320 back to its original position.

[0057] In this optional embodiment, the axial end of the first pressure roller 320 is supported by the bearing seat 344, which not only ensures that the first pressure roller 320 can rotate flexibly, but also bears the radial load generated during the flattening process, ensuring that the first pressure roller 320 operates smoothly and with low resistance, thus providing a basic condition for efficient flattening.

[0058] An elastic connector 343 (such as a spring) connects the sliding plate 342 and the bearing seat 344, allowing the first pressure roller 320 to float upwards when facing a stalk-shaped plant with a suddenly increased diameter. This effectively absorbs impact energy, preventing equipment damage and excessive crushing of the stalk-shaped plant. The elastic connector 343 constantly applies a downward elastic force to the bearing seat 344, ensuring that the first pressure roller 320 maintains a certain pressure on the stalk-shaped plant passing through the flattening interval, thus guaranteeing the continuity of the flattening effect.

[0059] The presence of the elastic connector 343 enables the first pressure roller 320 to automatically fine-tune its height according to the change in the diameter of the stalk plant, realizing adaptive flattening of stalk plants of different thicknesses and improving the versatility of the equipment.

[0060] By rotating the rod-shaped adjusting member 341 (such as an adjusting screw), the height position of the sliding plate 342 can be precisely changed, thereby altering the compression amount of the elastic connecting member 343 and achieving precise control over the initial height and flattening force of the first pressure roller 320. This adjustment method can meet the flattening parameter requirements of different raw materials, ensuring the accuracy and repeatability of the flattening quality.

[0061] The two pressure adjustment components 340 correspond to the two ends of the first pressure roller 320 respectively, and can be adjusted independently at both ends to ensure that the first pressure roller 320 remains horizontal, avoid uneven flattening caused by the tilt of the first pressure roller 320, and ensure the uniform thickness of the plant after flattening.

[0062] Optionally, combined Figure 3 As shown, the pressure regulating assembly 340 includes a telescopic rod 345, which is sleeved on the elastic connector 343. The top and bottom ends of the telescopic rod 345 are fixedly connected to the sliding plate 342 and the bearing seat 344, respectively.

[0063] Specifically, the telescopic rod 345 can adopt a sleeve structure, such as a telescopic sleeve composed of inner and outer sleeves, or a corrugated pipe, a telescopic sheath, etc. The inner diameter of the telescopic rod 345 is slightly larger than the outer diameter of the elastic connector 343, so that the elastic connector 343 can be accommodated in the internal cavity of the telescopic rod 345.

[0064] The fixed connection can be achieved through welding, threaded connection, flange connection, or bolt connection, ensuring that the telescopic rod 345 forms a robust integral structure with the sliding plate 342 and the bearing seat 344. Through this fixed connection, the telescopic rod 345 connects the sliding plate 342 and the bearing seat 344 together, forming a synchronously telescopic unit.

[0065] The two axial ends of the second pressure roller 330 can be fixedly or slidably connected to the sliding frame 310 through another bearing seat 344.

[0066] In this optional embodiment, the telescopic rod 345 is sleeved on the outside of the elastic connector 343, providing precise guidance for the telescopic movement of the elastic connector 343, ensuring that the elastic connector 343 is always compressed and reset in the vertical direction, avoiding bending or instability caused by lateral force, and ensuring the accuracy and reliability of pressure regulation.

[0067] The restraining effect of the telescopic rod 345 effectively prevents the elastic connector 343 from buckling when subjected to large pressure. Especially when the elastic connector 343 is compressed or subjected to impact, the telescopic rod 345 can maintain the shape stability of the elastic connector 343 and extend the service life of the elastic connector 343.

[0068] The telescopic rod 345 is fitted over the elastic connector 343, acting as a protective cover to prevent debris, dust, and other contaminants from the rod-shaped plant from entering the elastic connector 343. This prevents debris from entangled in or contaminating the elastic connector 343, ensuring its cleanliness and normal operation.

[0069] Optionally, combined Figure 3As shown, at least one of the sliding plate 342 and the bearing seat 344 is slidably connected to the sliding frame 310.

[0070] Specifically, the sliding frame 310 is a vertically arranged plate-like or frame structure, with a vertical guide rail on its inner side (i.e., the side facing the installation space). This guide rail can be implemented in various forms, such as a keyway, dovetail groove, linear guide rail, T-slot, or V-slot. The function of the guide rail is to guide the mating components (e.g., bearing housing 344) to move linearly in the vertical direction, and to restrict their displacement and rotation in the horizontal direction.

[0071] In the first implementation, the sliding plate 342 is slidably connected to the sliding frame 310, while the bearing seat 344 may not be directly slidably connected to the sliding frame 310, or may be indirectly guided by other means. Specifically, the side of the sliding plate 342 is provided with a guide structure that cooperates with the guide rail on the sliding frame 310, such as a guide groove, slider, or roller. The sliding plate 342 is embedded in the guide rail of the sliding frame 310 through this guide structure, so that the sliding plate 342 can slide vertically along the guide rail, but cannot move horizontally or rotate. The upper surface of the sliding plate 342 is connected to the rod-shaped adjusting member 341 (such as an adjusting screw), and the lower surface is connected to the bearing seat 344 through the elastic connector 343. Because the sliding plate 342 is precisely guided, even if the bearing seat 344 itself is not directly slidably connected to the sliding frame 310, it can still obtain a relatively stable motion trajectory through the elastic connector 343. The bearing housing 344 can maintain a roughly vertical direction of movement under the weight of the first pressure roller 320 and the elastic force of the elastic connector 343.

[0072] The second implementation involves a sliding connection between the bearing housing 344 and the sliding frame 310, where the sliding plate 342 may not be directly slidably connected to the sliding frame 310, or may be indirectly guided by other means. Specifically, the outer side of the bearing housing 344 is provided with a guide structure, such as a guide groove or a slider, that mates with the guide rail on the sliding frame 310. The bearing housing 344 is fitted onto the guide rail of the sliding frame 310 through this guide structure, allowing it to slide vertically along the guide rail but preventing horizontal movement or rotation. The bearing housing 344 internally supports the axial end of the first pressure roller 320 via a bearing. Above the bearing housing 344, the sliding plate 342 is connected to the bearing housing 344 via an elastic connector 343, and the sliding plate 342 itself may not directly contact the sliding frame 310, or may be prevented from detaching by a simple limiting structure.

[0073] Because the bearing housing 344 is precisely guided, it directly supports the first pressure roller 320, ensuring that the first pressure roller 320 always moves in a precise vertical direction. This is crucial for ensuring the parallelism of the upper and lower pressure rollers and the uniformity of the flattening interval. The sliding plate 342 moves with the bearing housing 344 and transmits elastic force through the elastic connector 343.

[0074] The third implementation: Both the sliding plate 342 and the bearing seat 344 are slidably connected to the sliding frame 310. Specifically, the sliding frame 310 is provided with two parallel guide rails, or a wider guide rail that simultaneously accommodates the sliding plate 342 and the bearing seat 344. The side of the sliding plate 342 is provided with a first guide structure that cooperates with the guide rail, and the side of the bearing seat 344 is provided with a second guide structure that cooperates with the guide rail. The sliding plate 342 and the bearing seat 344 are respectively embedded in the guide rail of the sliding frame 310 through their respective guide structures. Both can slide independently vertically along the guide rail, and both are constrained from moving horizontally or rotating.

[0075] In this optional embodiment, by setting the sliding plate 342 and / or the bearing seat 344 to be slidably connected to the sliding frame 310, a precise vertical guide is provided for the moving parts of the pressure regulating assembly 340, limiting their displacement and rotation in the horizontal direction, ensuring that the moving parts (sliding plate 342, bearing seat 344) always move in a straight line along a predetermined trajectory, fundamentally guaranteeing the smoothness and accuracy of the movement of the first pressure roller 320.

[0076] The guiding effect of the sliding connection effectively prevents the first pressure roller 320 from tilting or swaying during its up-and-down movement, ensuring that the first pressure roller 320 and the second pressure roller 330 always remain parallel. This ensures the consistency of the flattening interval along its entire length, making the thickness of the flattened rod-shaped plant uniform and significantly improving the flattening quality.

[0077] Optionally, combined Figure 1 and Figure 2 As shown, the first conveying assembly 200 includes a belt 210 and a plurality of drive rollers 220. The plurality of drive rollers 220 are spaced apart along the length direction of the first conveying assembly 200 and are mounted on the frame 100. The plurality of drive rollers 220 are connected by the belt 210.

[0078] Specifically, the multiple drive rollers 220 include a driving drive roller, a driven guide roller, and multiple idler rollers. The drive rollers 220, guide rollers, and idler rollers are all cylindrical rollers with parallel axes that are perpendicular to the conveying direction of the first conveying assembly 200. Both ends of these drive rollers 220 are rotatably mounted on the frame 100 via bearing seats 344, allowing each roller to rotate freely around its own axis.

[0079] The drive roller 220, acting as the driving roller, is installed at one end of the first conveying assembly 200 near the flattening mechanism 300 (i.e., the tail end). The roller shaft end of the drive roller 220 is equipped with a drive connector, such as a sprocket, for connection to an external power source. When an external power source drives the drive roller 220 to rotate, the drive roller 220 provides driving force to the entire conveying assembly.

[0080] The guide roller is installed at the end of the first conveying assembly 200 away from the flattening mechanism 300 (i.e., the starting end), and serves as a driven roller to change the running direction of the belt 210. The position of the guide roller can be adjusted by a tensioning device to adjust the tension of the belt 210.

[0081] Multiple drive rollers 220 are spaced apart along the length of the first conveying assembly 200 on the frame 100 between the drive rollers 220 and the guide rollers. Idler rollers are used to support the load-bearing section (upper belt 210) of the belt 210, preventing the belt 210 from sagging excessively under the weight of the material and ensuring the flatness of the conveying surface.

[0082] The belt 210 is an annular flexible belt, typically made of materials such as rubber, canvas, or plastic, possessing sufficient strength and wear resistance. The inner surface of the belt 210 contacts the outer surface of each drive roller 220, transmitting motion and power through friction. When the drive rollers 220 rotate, the friction between the belt 210 and the rollers drives the belt 210 to circulate, thereby conveying the rod-shaped plants it carries from the beginning to the end (i.e., towards the flattening mechanism 300).

[0083] In this optional embodiment, the parallel arrangement of multiple drive rollers 220 ensures that the belt 210 is subjected to uniform force and has a stable trajectory during operation, avoiding belt deviation, slippage, and other malfunctions, thus improving the reliability of the conveying process. The parallel arrangement of the drive rollers 220 provides a flat support base for the belt 210, keeping the conveying plane level and ensuring that the stalk-shaped plants remain stable during conveying, preventing them from rolling or slipping due to uneven conveying surfaces.

[0084] Multiple drive rollers 220 are connected by a belt 210, forming a continuous and flexible bearing surface above the drive rollers 220. This surface can support stalk-shaped plants of various lengths and shapes, offering strong adaptability. The flexibility of the belt 210 absorbs the impact of falling stalk-shaped plants, protecting the drive rollers 220 and the frame 100 from impact damage. It also reduces mechanical damage to vulnerable stalk-shaped plants, ensuring the integrity of the raw materials.

[0085] Optionally, combined Figure 1 and Figure 2As shown, the second conveying assembly 400 includes a plurality of support rollers 410 spaced apart. The plurality of support rollers 410 are spaced apart and installed on the upper part of the other end of the frame 100. The support rollers 410 are used to receive and convey the flattened rod-shaped plants.

[0086] Specifically, the support roller 410 is a cylindrical roller. Multiple support rollers 410 are arranged side-by-side and parallel along the conveying direction, with appropriate gaps between adjacent support rollers 410. Each support roller 410 is rotatably mounted at both ends to the longitudinal beams on both sides of the frame 100 via bearing seats 344 or bearings, allowing each support roller 410 to rotate freely around its own axis. The top surfaces of the support rollers 410 are essentially on the same horizontal plane, forming a continuous, flat conveying plane for supporting and conveying the flattened rod-shaped plants.

[0087] In this optional embodiment, the flattened stalk-shaped plants need to be output from the flattening mechanism 300 and conveyed forward for subsequent processing. The spaced support rollers 410 form a roller conveyor that can receive and transport the stalk-shaped plants, replacing manual collection, greatly reducing labor intensity and improving output efficiency.

[0088] Optionally, combined Figure 2 and Figure 4 As shown, the flipping mechanism 500 includes a first driving device 510, a connecting rod assembly 520, a first rod 530, and a plurality of second rods 540. The plurality of second rods 540 are alternately distributed with the plurality of support rollers 410. The plurality of second rods 540 are respectively connected to the first rods 530. The first rods 530 are rotatably connected to the frame 100, and the axis of rotation is consistent with the conveying direction of the second conveying assembly 400. The two ends of the connecting rod assembly 520 are respectively connected to the first driving device 510 and the first rods 530, and are used to drive the first rods 530 and the plurality of second rods 540 to rotate under the drive of the first driving device 510, so that the second rods 540 switch between the working state and the reset state.

[0089] Specifically, at least one second rod 540 is provided between at least some of the adjacent support rollers 410.

[0090] The second member 540 is perpendicular to and fixedly connected to the first member 530.

[0091] The first drive unit 510 is a geared motor. The geared motor can be fixedly mounted on the frame 100 and is located on one side of the second conveying assembly 400, as shown below. The output shaft of the first drive unit 510 has a connecting flange or keyway for connection to the connecting rod assembly 520. The flattening device suitable for stalk-shaped plants also includes a control system (such as a PLC or relay control circuit). The first drive unit 510 is electrically connected to the control system, which can be existing technology. The first drive unit 510 serves as the power source for the flipping mechanism 500, and its start, stop, and rotation direction are controlled by the control system.

[0092] The first rod 530 can be made of square tubing. The first rod 530 is a square-section tubing of a certain length, arranged along the length of the second conveying assembly 400, i.e., parallel to the conveying direction. Both ends or the portion between the two ends of the first rod 530 can be rotatably mounted on the frame 100 via bearing seats 344 or hinges, allowing the first rod 530 to rotate around its own axis. The axis of rotation of the first rod 530 can be aligned with its own axis and the conveying direction of the second conveying assembly 400. The first rod 530 serves as the main shaft of the tilting mechanism 500, used to mount multiple second rods 540 and transmit rotational motion.

[0093] Multiple second members 540 are spaced apart along the length of the first member 530 and are fixedly connected to the first member 530 respectively. The fixed connection can be achieved by welding, threaded connection or bolt connection, etc., to ensure that the second member 540 and the first member 530 form a strong integral structure. The second member 540 is a slender rod-shaped member, and its length direction is perpendicular to the axis (or length direction) of the first member 530.

[0094] When the first rod 530 or the second rod 540 is in the reset state, each second rod 540 is located in the gap between two adjacent support rollers 410, and its top end is lower than or flush with the conveying surface of the support roller 410; when the first rod 530 or the second rod 540 is in the working state, each second rod 540 rotates to the upper right, and its top end is higher than the conveying surface of the support roller 410.

[0095] In this optional embodiment, the linkage assembly 520 converts the rotational motion of the first driving device 510 into the reciprocating swing motion of the first link 530, realizing the conversion of motion form from power source to actuator, and meeting the swing motion requirements of the tilting mechanism 500. Through the transmission of the linkage assembly 520, the second link 540 can reliably switch between the working state (raised) and the reset state (lowered), ensuring the normal alternation of the two functions of conveying and unloading.

[0096] Multiple second rods 540 are connected to the same first rod 530, ensuring that all second rods 540 can rise and fall completely synchronously during the unloading process, avoiding incomplete unloading or stick-shaped plant jamming caused by asynchronous actions. The design of connecting multiple second rods 540 to a single first rod 530 simplifies the transmission structure, requiring only one first drive unit 510 and one set of connecting rods 520 to drive multiple unloading actuators, reducing cost and failure rate.

[0097] The alternating distribution of the second rod 540 and the support roller 410 allows the flipping mechanism 500 to directly utilize the gap between the support rollers 410 as its working space, eliminating the need to set up a separate action area for the flipping mechanism 500. This significantly saves equipment space and makes the overall structure more compact.

[0098] Optionally, combined Figure 2 and Figure 4 As shown, the connecting rod assembly 520 includes a crank 521, a connecting rod 522, and a rocker arm 523; the first driving device 510 is connected to one end of the crank 521 and is used to drive the crank 521 to rotate; the two ends of the connecting rod 522 are respectively rotatably connected to the other end of the crank 521 and one end of the rocker arm 523; the other end of the rocker arm 523 is fixedly connected to the first rod 530; the rocker arm 523 is used to drive the first rod 530 and the second rod 540 to rotate relative to the frame 100.

[0099] Specifically, the crank 521, connecting rod 522, and rocker arm 523 together constitute a crank-rocker mechanism, which is used to convert the rotational motion of the first drive device 510 into the reciprocating oscillating motion of the first rod 530.

[0100] The first driving device 510 is a geared motor. The first driving device 510 is fixedly installed on the frame 100, and its output shaft protruding end is provided with a connecting keyway or flat key for fixed connection with one end of the crank 521.

[0101] Crank 521 is a rod-shaped component with a shaft hole at one end, which is fixedly connected to the output shaft of the first driving device 510 via a key or set screw. The other end of crank 521 has a first hinge hole for rotatably connecting to one end of connecting rod 522. The length of crank 521 (i.e., the distance between the axis of the output shaft of the first driving device 510 and the axis of the first hinge hole) determines the stroke of connecting rod 522 and the swing angle of rocker arm 523. Depending on actual needs, the length of crank 521 can be selected to obtain the required swing amplitude. For example, a longer crank 521 can be selected when a larger unloading angle is required; a shorter crank 521 can be selected when a smaller angle is required.

[0102] The connecting rod 522 is a rod-shaped component with a second hinge hole and a third hinge hole at each end. The second hinge hole at one end of the connecting rod 522 is rotatably connected to the first hinge hole of the crank 521 via a pin, and the third hinge hole at the other end of the connecting rod 522 is rotatably connected to one end of the rocker arm 523 via a pin. The length of the connecting rod 522 (i.e., the distance between the axes of the second and third hinge holes) is matched with the length of the crank 521, the length of the rocker arm 523, and the required motion trajectory, collectively determining the motion characteristics of the entire linkage mechanism.

[0103] The rocker arm 523 is a rod-shaped component with a fourth hinge hole at one end, which is used to rotatably connect with the third hinge hole of the connecting rod 522 via a pin. The other end of the rocker arm 523 is fixedly connected to the first rod 530. The fixed connection can be achieved by welding, keying, or bolting, ensuring that the rocker arm 523 and the first rod 530 form a robust integral structure.

[0104] Wear-resistant bushings or rolling bearings are provided at the rotating joints of crank 521, connecting rod 522, and rocker arm 523 to reduce friction and wear, ensuring smooth movement and extended service life. Cotter pins or elastic retaining rings are provided at the ends of each pin to prevent them from falling off.

[0105] In this optional embodiment, when the control system issues an unloading command, the first driving device 510 is activated, driving the crank 521 to rotate. Assume the crank 521 starts rotating clockwise from its initial position (corresponding to the reset state). As the crank 521 rotates, its end drives the connecting rod 522 to move, and the connecting rod 522 then transmits the motion to the swing rod 523. The swing rod 523, pushed by the connecting rod 522, swings around the axis of the first rod 530, thereby driving the first rod 530 to rotate. The rotation of the first rod 530 causes the second rod 540 fixed thereon to rotate synchronously, causing the second rod 540 to rise from the gap between the support rollers 410, exceeding the conveying surface of the second conveying assembly 400, thus blocking and unloading the flattened rod-shaped plant (reed).

[0106] When crank 521 rotates to a certain angle (e.g., greater than or equal to 90 degrees), the second rod 540 rises to its highest point, completing the unloading action. At this time, the control system can control the first drive component 510 to pause, maintaining the unloading state for a period of time so that the rod-shaped plant can be completely unloaded. Then, the control system controls the first drive component 510 to continue rotating or rotate in the opposite direction, causing crank 521 to continue moving or return to its initial position. Through connecting rod 522 and swing rod 523, the first rod 530 and the second rod 540 are reset. The second rod 540 descends back into the gap between the support rollers 410, below or flush with the conveying surface of the second conveying assembly 400, and the flipping mechanism 500 returns to the reset state.

[0107] The first driving component 510 is directly connected to one end of the crank 521, reducing intermediate transmission links, lowering energy loss and transmission errors, and improving transmission accuracy. The connecting rod 522 is rotatably connected to both ends of the crank 521 and the rocker arm 523, allowing the connecting rod 522 to automatically adjust its angle during movement, ensuring the flexibility of the tilting mechanism 500 and preventing jamming. The fixed connection between the rocker arm 523 and the first link 530 ensures that the swing of the rocker arm 523 is transmitted to the first link 530 without loss or delay, enabling completely synchronized movement between the two.

[0108] Optionally, combined Figure 2 As shown, the flattening device for stalk-shaped plants also includes a second drive unit 610 and a chain drive system 620. The second drive unit 610 is drivenly connected to the chain drive system 620. The drive roller 220, the support roller 410 and the roller pressing assembly are respectively drivenly connected to the chain drive system 620 and are used to operate simultaneously under the drive of the chain drive system 620.

[0109] Specifically, the second drive device 610 adopts a main geared motor, which is fixedly installed on the frame 100, usually located in the middle or rear of the entire frame 100, to facilitate power transmission with various working parts.

[0110] The axial ends of the drive roller 220, the support roller 410, and the first pressure roller 320 and the second pressure roller 330 of the roller pressing assembly are respectively connected to the chain drive system 620.

[0111] In this optional embodiment, the direct drive connection between the second drive device 610 and the chain drive system 620 ensures that power can be efficiently and stably input into the chain drive system 620, reducing energy loss in intermediate transmission links.

[0112] The second drive device 610 is electrically connected to the control system. By controlling the start, stop and speed of the second drive device 610, the operating status of all working parts can be controlled simultaneously, which simplifies the control system and improves the convenience of operation.

[0113] The chain drive system 620 simultaneously distributes the power of the second drive component 610 to the drive roller 220, the support roller 410, and the roller pressing assembly, realizing the function of driving multiple working parts with a single power source. This allows the operation to be staggered from the turning and unloading operation of the turning mechanism 500, which not only avoids conflicts between the conveying and flattening of the rod-shaped plants and the unloading operation, but also reduces the motor investment cost of the equipment.

[0114] Optionally, combined Figures 4 to 6As shown, the chain drive system 620 includes a first sprocket 621, a second sprocket 622, a third sprocket 623, a fourth sprocket 624, a fifth sprocket 625, a sixth sprocket 626, a seventh sprocket 627, an eighth sprocket 628, a ninth sprocket 629, a first chain, a second chain, a third chain, a fourth chain, and a fifth chain. The first sprocket 621 and the fifth sprocket 625 are fixedly sleeved on the output shaft of the second drive device 610. The second sprocket 622 and the third sprocket 623 are fixedly sleeved on the axial end of the second pressure roller 330. The axial end of the first pressure roller... A fourth sprocket 624 is fixedly mounted on the first sprocket 621 and the second sprocket 622. A second chain is mounted on the third sprocket 623 and the fourth sprocket 624. Therefore, when the second driving device 610 is working, it drives the first sprocket 621 to rotate, which in turn drives the second sprocket 622 and the second pressure roller 330 to rotate via the first chain. The third sprocket 623 at the end of the second pressure roller 330 drives the fourth sprocket 624 at the end of the first pressure roller 320 to rotate via the second chain, thereby realizing the rotational drive of the first pressure roller 320 and the second pressure roller 330.

[0115] In the second conveying assembly 400, a sixth sprocket 626, a seventh sprocket 627, and an eighth sprocket 628, spaced axially at the end of one support roller 410 near the pressure roller assembly, are fitted with the seventh sprocket 627. A third chain is fitted onto the fifth sprocket 625 and the sixth sprocket 626 at the axial end of the second driving device 610. The seventh sprocket 627 at the end of one support roller 410 and the sprockets 628 at the ends of the other support rollers 410 are also fitted with the seventh sprocket 627. The seventh sprocket 627 is connected via the fourth chain; therefore, when the second driving device 610 is working, it drives the first sprocket 621 and the fifth sprocket 625 to rotate. The fifth sprocket 625 drives the sixth sprocket 626 and the seventh sprocket 627 at the end of a support roller 410 to rotate via the third chain. The seventh sprocket 627 at the end of a support roller 410 drives the seventh sprocket 627 of other support rollers 410 to rotate via the fourth chain, thereby realizing the rotational drive of the multiple support rollers 410 of the second conveying assembly 400.

[0116] A ninth sprocket 629 may be fitted onto the end of at least one drive roller 220 in the first conveying assembly 200. A fifth chain is wound around an eighth sprocket 628 at the end of a support roller 410 and the ninth sprocket 629 at the end of the drive roller 220. Therefore, when the second driving device 610 is working, the sixth sprocket 626, the seventh sprocket 627, and the eighth sprocket 628 at the end of the support roller 410 are rotated via the fifth sprocket 625 and the third chain. The eighth sprocket 628 drives the ninth sprocket 629 at the end of the drive roller 220 to rotate via the fifth chain, thereby realizing the rotational drive of the belt 210 of the first conveying assembly 200.

[0117] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
