Description

Technical Field

[0001] This invention relates to the field of sugarcane harvesting technology, and in particular to a sugarcane combine harvester with a tail-cutting device. Background Technology

[0002] Traditional sugarcane harvesting is labor-intensive and inefficient. While early mechanical harvesters enabled large-scale operations, they lacked precise tail-cutting mechanisms, making it difficult to effectively handle sugarcane tails with low sugar content. This not only increased the impurity rate and cost in the sugar production process but also wasted the potential value of sugarcane tails as livestock feed. Furthermore, manually adjusting the cutting height could easily lead to cutting point deviation, and the elastic nature of sugarcane made un-clamped cutting unreliable. Therefore, sugarcane harvesters with tail-cutting devices were developed to address many of the pain points of traditional equipment.

[0003] Most sugarcane combine harvesters currently on the market are at a semi-mechanized level, with extremely simple functional designs, primarily meeting only basic cutting needs. These machines generally use simple circular saws or reciprocating blades as their core working components, only able to roughly cut the sugarcane roots during operation. After cutting, they lack any stable positioning or transfer structure, and the sugarcane falls to the field entirely by its own weight. Most models are not equipped with a dedicated tail-cutting structure, and the tail-cutting process relies entirely on manual operation. The unloading process lacks any auxiliary design, and the cut sugarcane is simply piled up haphazardly. Processes such as turning the soil and cleaning up residual roots are entirely done by independent agricultural machinery or manual labor, and are completely unrelated to the harvesting process.

[0004] The drawbacks of this type of harvester are extremely significant. First, it is highly dependent on manual labor. After cutting, the sugarcane is scattered and needs to be manually gathered. The tail trimming and impurity cleaning all rely on manual intervention, resulting in low overall operating efficiency. Second, the subsequent processes are cumbersome. After harvesting, separate personnel or equipment are needed to collect the sugarcane, clean up the residual roots, and turn the soil, which greatly increases the labor intensity and time cost. It is completely unsuitable for the needs of large-scale and efficient sugarcane planting.

[0005] Chinese Patent Publication No. CN102197739A discloses a sugarcane combine harvester with a tail-cutting device, including a power system, an operating system, a front gathering mechanism, a cutting mechanism, and a leaf-peeling and tail-cutting mechanism disposed behind the cutting mechanism. The leaf-peeling and tail-cutting mechanism has a sugarcane transport channel and a tail-cutting device. The tail-cutting device includes at least one pair of tail-cutting wheels arranged vertically within the sugarcane transport channel. Each pair of tail-cutting wheels includes a first tail-cutting wheel and a second tail-cutting wheel. Both the first and second tail-cutting wheels include their respective mounting shafts and rollers. Multiple elastic ribs extending axially and radially along the outer circumference of the rollers are evenly distributed. The outer end faces of the elastic ribs of the second tail-cutting wheel are serrated curved surfaces. This sugarcane combine harvester with a tail-cutting device can effectively cut off the tender stalk portion of the sugarcane tail, and the tail-cutting device of this combine harvester provides a good tail-cutting effect. However, the aforementioned device cannot clean the sugarcane roots and lacks soil treatment capabilities. Summary of the Invention

[0009] Preferably, the sliding block on the left is L-shaped, and the sliding block on the right is fixedly connected to the corresponding movable seat in diameter.

[0010] Preferably, the inner surfaces of both movable seats are rotatably connected to the conveying mechanism.

[0011] Preferably, the harvesting assembly includes two fixed seats II fixedly connected to the front end of the mobile base. Each of the two fixed seats II has a through groove I on its side that is far apart from each other. A bidirectional shaft motor is fixedly installed at the lower end of each of the two fixed seats II. A circular saw is fixedly connected to the output end of each of the two bidirectional shaft motors. A support base is fixedly connected to the lower end of each of the two fixed seats II. A guide plate is fixedly connected inside the fixed seat II and above a plurality of gears.

[0012] Preferably, the inner surface of the left-side fixed seat 2 is provided with a through groove 2, and the rear sides of both fixed seats 2 are provided with sliding grooves.

[0013] Preferably, the striking assembly includes several rotating shafts, the top walls of the inner surfaces of the two fixed seats are rotatably connected to the several rotating shafts, the outer surfaces of the several rotating shafts are fixedly connected with striking plates, the lower ends of the several rotating shafts are fixedly connected with gears, the several gears are meshed with each other, and the output ends on the upper side of the two circular saws are fixedly connected to gears at appropriate positions.

[0014] Preferably, the unloading assembly includes a belt drive assembly, a reciprocating rod is rotatably connected to the inner surface of the sliding groove, the upper end of the rotating shaft located at the left rear end is connected to the reciprocating rod via the belt drive assembly, a sliding block is slidably connected to the outer surface of the reciprocating rod, and a lifting plate is fixedly connected to the lower end of the sliding block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the cooperation of various components, this invention can clamp and transport sugarcane immediately after harvesting. During this process, the sugarcane can be peeled off by the beating component to remove attached soil clods and tangled weeds. It can also be cut off by the tail-cutting machine while being clamped by the clamping component, avoiding cutting deviation caused by the sugarcane shaking during tail cutting. After tail cutting, the unloading component allows the sugarcane to tilt and unload to the preset opening side by its own weight. Furthermore, the soil turning mechanism forms a continuous mode of front harvesting and back turning with the harvesting operation, eliminating the separate back-and-forth soil turning process in traditional operations and greatly shortening the total time spent in the field.

[0017] 2. This invention first harvests and transports sugarcane through a conveying mechanism and a harvesting component. During transportation, the moving seat and the conveying mechanism can simultaneously clamp and transport the sugarcane. During transportation, the cooperation of the beating component and the unloading component can not only make several high-speed rotating beating blades beat the sugarcane roots, effectively removing attached soil clods and tangled weeds, but also stably lift and support the sugarcane roots, allowing them to tilt towards the preset opening side by their own weight. At the same time, the soil can be turned over, turning the surface weeds and sugarcane root residues into the deeper soil layers. This can not only reduce the germination of weed seeds, but also allow the residues to decompose naturally in the soil and be converted into organic nutrients, completely solving the problems of scattered processes and poor connection in traditional semi-mechanized operations.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1-2 As shown, a sugarcane combine harvester with a tail-cutting device includes a mobile base 1, a handrail 11 fixedly connected to the upper end of the mobile base 1, a hydraulic device 12 installed at the upper end of the mobile base 1, a tail-cutting cutter 13 fixedly installed at the output end of the hydraulic device 12, a clamping assembly 2 provided at the upper end of the mobile base 1, a conveying mechanism 3 for conveying and clamping sugarcane provided at the front end of the clamping assembly 2, a harvesting assembly 4 for harvesting sugarcane provided at the front end of the mobile base 1, a patting assembly 5 provided at the lower end of the conveying mechanism 3, and a unloading assembly 6 provided at the front end of the mobile base 1, the unloading assembly 6 including a soil-turning mechanism 68.

[0022] During the operation of this embodiment, through the cooperation of various components, the sugarcane can be clamped and transported immediately after harvesting. During this process, the sugarcane can be peeled off the attached soil clods and tangled weeds by the beating component 5, and the sugarcane can also be cut off by the tail cutter 13 while being clamped by the clamping component 2. This avoids the cutting deviation caused by the sugarcane shaking during tail cutting. After tail cutting, the unloading component 6 is used to make the sugarcane tilt and unload to the preset opening side by its own weight. Furthermore, the soil turning mechanism 68 forms a continuous mode of front harvesting and back turning with the harvesting operation, eliminating the separate back-and-forth soil turning process in traditional operations and greatly shortening the total time spent in the field.

[0023] Example 2, as Figure 1-9 The clamping assembly 2 includes a fixed base 21 fixedly connected to the upper end of the movable base 1. A bidirectional threaded rod 22 is rotatably connected to the inner surface of the fixed base 21. The bidirectional threaded rod 22 is connected to an external power source. Two threaded sleeves 23 are threadedly connected to the outer surface of the bidirectional threaded rod 22. A connecting rod 24 is fixedly connected to the end of each of the two threaded sleeves 23 that is close to each other. A sliding block 25 is fixedly connected to the end of each of the two connecting rods 24 that is close to each other. The two sliding blocks 25 are slidably connected to the outer surface of the bidirectional threaded rod 22.

[0024] Specifically, the threads on both sides of the surface of the bidirectional threaded rod 22 are in opposite directions. When the bidirectional threaded rod 22 is driven to rotate by an external power source, it will drive the two threaded sleeves 23 to move synchronously in opposite directions, thereby causing the two moving seats 26 to move towards the middle to clamp the harvested sugarcane. This will keep the cut sugarcane upright and effectively prevent it from tipping over, misaligning, or turning over during subsequent movement, providing a stable foundation for subsequent processes such as beating to remove impurities and cutting off the tail.

[0025] The sliding block 25 on the left is L-shaped, while the sliding block 25 on the right is fixedly connected to the corresponding movable seat 26.

[0026] Furthermore, the L-shaped design of the left sliding block 25 allows the sugarcane to tilt directly to the left after being lifted, facilitating the orderly unloading of the sugarcane.

[0027] The inner surfaces of both movable seats 26 are rotatably connected to the transmission mechanism 3.

[0028] The aforementioned conveying mechanism 3 is a conventional technology in the prior art. The two conveying mechanisms 3 are arranged relatively parallel, and the distance between them can be adjusted according to the movement of the moving seat 26. Together with the tensioning device, they maintain a moderate clamping force, preventing the sugarcane from tipping over without damaging the stalk. The drive system drives the two conveying mechanisms 3 to rotate in opposite directions at completely synchronized speeds. The belt surface is made of non-slip rubber or has added raised textures to enhance friction with the sugarcane surface. When the sugarcane is fed into the clamping gap between the two conveying mechanisms 3, the conveying mechanisms 3 use friction to drive the sugarcane to move backward synchronously with the belt, maintaining an upright posture throughout the process.

[0029] The clamped sugarcane moves smoothly backward along a predetermined path, achieving a continuous connection between cutting and subsequent processing steps, avoiding pauses and waiting between steps, significantly improving overall operational efficiency, and meeting the continuous operation requirements of large-scale harvesting. The harvesting assembly 4 includes two fixed seats 41 fixedly connected to the front end of the mobile base 1. Each of the two fixed seats 41 has a through groove 411 on its side away from each other. A bidirectional shaft motor 42 is fixedly installed at the lower end of each of the two fixed seats 41. A circular saw 43 is fixedly connected to the output end of each of the two bidirectional shaft motors 42. A support base 44 is fixedly connected to the lower end of each of the two fixed seats 41. A guide plate 45 is fixedly connected inside the fixed seat 41 and above a plurality of gears 51.

[0030] The support base 44 can support the bottom of the harvested sugarcane so that it does not fall directly onto the soil after being harvested.

[0031] The inner surface of the left fixed seat 41 is provided with a through groove 412, and the rear side of both fixed seats 41 is provided with a sliding groove 413.

[0032] The aforementioned bidirectional shaft motor 42 is existing technology. It is a power device that achieves bidirectional torque output through the principle of electromagnetic induction. Its core consists of a stator, rotor, and a through-type output shaft. Its working principle is based on the law of electromagnetic induction: when three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated. The rotor conductors cut magnetic lines of force in this rotating magnetic field, inducing a current. The charged rotor conductors are subjected to electromagnetic force in the stator magnetic field, driving the rotor to rotate around its axis. This, in turn, drives the bidirectional output shaft through the rotor to rotate synchronously. The key feature of the bidirectional shaft motor 42 is that the output shaft passes through both ends of the motor housing, allowing for stable torque output from both ends with completely consistent direction of rotation. Bearings and sealing structures ensure the coaxiality and sealing of the transmission at both ends, preventing dust and impurities from affecting operation. Direction adjustment is achieved by changing the current phase sequence of the stator windings, eliminating the need for additional mechanical commutation structures and allowing flexible switching between forward and reverse directions to adapt to the power requirements of different operating scenarios. Its compact structure and balanced torque output allow it to simultaneously power two related devices or achieve high torque output at one end. It is widely used in industrial equipment requiring bidirectional transmission or synchronous drive, and therefore will not be elaborated upon in this solution.

[0033] Furthermore, the guide plate 45 is inclined towards the channel 411, which can drain the soil or weeds that have entered the fixed seat 41 through the channel 411, without affecting the operation of the harvesting component 4.

[0034] The device is moved to the sugarcane location to be harvested. Two bidirectional shaft motors 42 are started to rotate the circular saw 43. The moving device guides the sugarcane between two fixed seats 41. An external power source is activated to rotate the bidirectional threaded rod 22, which drives the two moving seats 26 and the conveying mechanism 3 to move synchronously towards the center, thus limiting the sugarcane entering between the two fixed seats 41. During the entry process, the circular saw 43 cuts off all the roots of the sugarcane, allowing the cut sugarcane to be moved to the rear of the device by the conveying mechanism 3. During the rearward movement, the tail-cutting machine 13 cuts off the tail of the sugarcane, effectively removing the redundant parts of the sugarcane tail that are severely fibrous and have low nutritional value. The tail-cutting is completed without interrupting the overall operation process, ensuring the continuity of the operation and avoiding the decrease in efficiency caused by the separate tail-cutting process.

[0035] The striking assembly 5 includes several rotating shafts 52. The top walls of the inner surfaces of the two fixed seats 41 are rotatably connected to the several rotating shafts 52. The outer surfaces of the several rotating shafts 52 are all fixedly connected with striking plates 53. The lower ends of the several rotating shafts 52 are all fixedly connected with gears 51. The several gears 51 are meshed with each other. The output ends on the upper side of the two circular saws 43 are all fixedly connected to the gears 51 in the appropriate positions.

[0036] Furthermore, the bidirectional shaft motor 42 can synchronously drive the gear 51 to rotate, thereby driving several rotating shafts 52 and the beating plate 53 to rotate synchronously, beating the sugarcane root area during transportation. This can effectively remove weeds, soil and other impurities attached to the sugarcane root without causing impact damage to the sugarcane root and stalk, avoiding problems such as sugarcane skin damage and stalk breakage, and ensuring the commercial value of the sugarcane after harvesting.

[0037] Furthermore, the interior of the rotating shaft 52 is made of high-toughness spring steel to ensure sufficient elasticity and impact force during beating, effectively removing soil and weeds from the roots, and is not easily deformed or broken; the outer surface of the beating part that comes into contact with the sugarcane is covered with wear-resistant polyurethane or food-grade rubber, whose softness can prevent scratching the sugarcane skin and damaging the stem fibers. At the same time, the anti-slip and wear-resistant properties of the rubber are suitable for complex environments such as field soil and moisture, extending the service life of the device and meeting the needs of continuous operation.

[0038] The unloading assembly 6 includes a belt drive assembly 61, a reciprocating rod 62 rotatably connected to the inner surface of the sliding groove 413, the upper end of the rotating shaft 52 located at the left rear end is connected to the reciprocating rod 62 via the belt drive assembly 61, a sliding block 63 is slidably connected to the outer surface of the reciprocating rod 62, and a lifting plate 64 is fixedly connected to the lower end of the sliding block 63.

[0039] The reciprocating rod 62 and the sliding block 63 mentioned above are ball screw mechanisms in the prior art. When the reciprocating rod 62 rotates in one direction, it can drive the sliding block 63 to move up and down reciprocally.

[0040] The belt drive assembly 61 consists of two pulleys of different diameters and a belt. The pulley connected to the reciprocating rod 62 has a larger diameter and a slower rotation speed.

[0041] In the initial state, the lifting plate 64 is parallel to the support base 44. When the rotating shaft 52 rotates, it will drive the reciprocating rod 62 to rotate, thereby causing the lifting plate 64 to move up and down. During the movement, when the lifting plate 64 rises, it will lift the sugarcane that has moved to that position. The lifted sugarcane will tilt towards the notch of the left sliding block 25 due to the unstable center of gravity, thus completing the orderly feeding. When the lifting plate 64 is on the upper side, the sugarcane is temporarily blocked and piled up in place, waiting for the lifting plate 64 to fall before moving above it.

[0042] The lower end of the reciprocating rod 62 is fixedly connected to a bevel gear transmission assembly 65, and the lower end of the left fixed seat 41 is fixedly connected to a housing 66. The bevel gear transmission assembly 65 is located in the inner cavity of the housing 66 and is rotatably connected to a rotating shaft 67. The rotating shaft 67 extends to the outside of the housing 66 and is rotatably connected to the right fixed seat 41. A soil turning mechanism 68 is fixedly connected to the outer surface of the rotating shaft 67.

[0043] The bevel gear transmission group 65 mentioned above consists of two meshing bevel gears, which cause the soil turning mechanism 68 to rotate synchronously with it to turn the soil after the sugarcane is harvested. This forms a continuous mode of harvesting before turning the soil, eliminating the separate back-and-forth turning process in traditional operations and greatly shortening the total time spent in the field. During the turning process, weeds and sugarcane residues on the surface can be turned into the deeper soil layers, which can reduce the germination of weed seeds and allow the residues to decompose naturally in the soil and be transformed into organic nutrients, realizing the recycling of resources and improving the overall fertility of the soil.

[0044] Therefore, this solution first harvests and transports sugarcane through the conveying mechanism 3 and the harvesting component 4. During the transportation process, the moving seat 26 and the conveying mechanism 3 can simultaneously clamp and transport the sugarcane. During the transportation process, through the cooperation of the beating component 5 and the unloading component 6, several high-speed rotating beating plates 53 can be used to beat the sugarcane roots, effectively removing the attached soil clods and tangled weeds. The sugarcane roots can also be stably supported and supported, allowing them to tilt towards the preset opening side by their own weight. At the same time, the soil can be turned over, turning the weeds and sugarcane root residues on the surface into the deeper soil layers. This can reduce the germination of weed seeds and allow the residues to decompose naturally in the soil, transforming them into organic nutrients. This completely solves the problems of scattered processes and poor connection in traditional semi-mechanized operations.

[0045] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic device 12, tail cutting machine 13, conveying mechanism 3 and bidirectional shaft motor 42 used in this invention are all conventional designs, and will not be described in detail in this invention.
