Abstract

This invention discloses an integrated machine for leveling, leaf-crushing, ridging, deep loosening, fertilizing, and managing ratoon sugarcane, comprising a frame, a fertilizing device, a coppicing device, a ridging and loosening device, limiting wheels, and a scraper. This integrated machine for leveling, leaf-crushing, ridging, deep loosening, fertilizing, and managing ratoon sugarcane effectively shortens the distance between the two devices by tilting the ridging and loosening device towards the coppicing device. The overall structure is smaller and more compact, reducing the likelihood of missed areas during operation. The tilted arrangement of the ridging and loosening device also reduces resistance and improves the machine's operating efficiency. Simultaneously, a serrated scraper is installed between the coppicing and ridging / loosening devices to break up large clumps of soil turned over by either device, promoting the germination and growth of the ratoon sugarcane. The scraper is hinged to the mudguard of the frame or coppicing device and can elastically swing within a certain range according to the size of the soil clumps, which helps to pat down the clumps and reduces the machine's resistance.

Description

Technical Field

[0001] This invention belongs to the field of agricultural management machinery, and specifically relates to an integrated machine for managing perennial sugarcane by leveling the base, breaking up leaves, breaking ridges, deep loosening, and fertilizing. Background Technology

[0002] Sugarcane is a perennial high-biomass crop. After the previous year's sugarcane harvest, the buds of the sugarcane stubble remaining in the soil sprout and grow into sugarcane plants under suitable environmental conditions (mainly temperature and humidity), known as ratoon sugarcane. In production, the ratooning period is generally 2-3 years, but can reach 4-5 years in some cases. Ratoon sugarcane typically accounts for about 70% of the planted sugarcane area, and its growth directly affects the total sugarcane yield of the following year. Therefore, proper management of ratoon sugarcane is crucial in sugarcane cultivation.

[0003] Currently, the management of ratooned sugarcane in sugarcane-growing areas has gradually become mechanized. The inventors of this application previously researched ratooned sugarcane management machines, such as the patent "A Ratooned Sugarcane Management Machine and Its Application" (CN115885605A). This ratooned sugarcane management machine is equipped with a frame, fertilization device, coppicing device, stubble cutting and tilling device, ridge breaking and loosening device, and limiting wheels. It can simultaneously perform coppicing, shoveling, tilling, loosening, and fertilization operations on ratooned sugarcane planted in wide and narrow rows or with equal row spacing. It is convenient and labor-saving to operate, while ensuring that the ratooned sugarcane grows within a reasonable area, without occupying the inter-row farm roads, and is also beneficial for mid-term cultivation and hilling operations. However, this management machine is mainly suitable for use in wide and narrow row planting areas where growth is uneven and easily encroaches on roads. For ordinary sugarcane planting areas, this management machine has problems such as being too long and having high resistance, often resulting in incomplete field management. For example, the coppicing device may complete coppicing, but the ridge breaking and loosening device may still leave a section untouched, leading to missed operations. The high resistance of the cutting and turning device can also affect the efficiency of the management machine. On the other hand, although the pruning device can crush sugarcane leaves and weeds, loosen the topsoil, and remove the upper part of the sugarcane stalk, it can sometimes bring out some large clods of soil, which is not conducive to the germination and growth of ratooned sugarcane. In addition, the area where the pruning device is used has a lot of sugarcane leaves, which can easily accumulate and affect the efficiency of the management machine. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machine for leveling the base of ratoon sugarcane, breaking up leaves, mulching, deep loosening, fertilizing, and managing the plant, thereby overcoming the problems of missed operations and low efficiency of existing ratoon sugarcane management machines.

[0005] To achieve the above objectives, the present invention provides an integrated machine for leveling, leaf breaking, ridging, deep loosening, fertilizing, and managing perennial sugarcane, comprising a frame, a connecting part at the front end of the frame, a fertilizing device above the frame, and a coppicing device, a ridging and loosening device, and limiting wheels below the frame. The ridging and loosening device is located on both sides behind the coppicing device, and the limiting wheels are located on both sides or behind the ridging and loosening device. The limiting wheels are detachably connected to the frame via connecting rods with threaded holes; characterized in that the ridging and loosening device... The device includes a ridge-breaking plow, a soil-loosening board, and a connecting plate. The connecting plate is inclined downwards and forwards (towards the end of the coppicing device). The ridge-breaking plow is installed at the front bottom of the connecting plate. The soil-loosening board is installed on the connecting plate behind the ridge-breaking plow. The soil-loosening board is triangular or trapezoidal in shape, narrower at the front and wider at the back. A soil scraper is also provided between the coppicing device and the ridge-breaking and soil-loosening device. The soil scraper is inclined downwards and backwards. The bottom of the soil scraper is higher than the coppicing device and the ridge-breaking and soil-loosening device. The bottom of the soil scraper is serrated.

[0006] The machine operates in the forward direction, with the leveling device located at the front of the frame and the ridge-breaking and loosening device located at the rear of the frame.

[0007] This application sets the ridge-breaking and loosening device at an angle forward, which shortens the distance between the coppicing device and the ridge-breaking and loosening device, making it less likely that the work will be missed. Furthermore, setting the ridge-breaking and loosening device at an angle forward also reduces resistance.

[0008] Preferably, the front end of the scraper is equipped with a leaf-crushing blade, the position of which corresponds to the position of the connecting plate and is located above the ridging plow. The leaf-crushing blade can further separate the sugarcane leaves on the ratooned sugarcane surface, preventing the leaves from tangling and piling up.

[0009] Preferably, the leaf-crushing blade is square and is inclined along with the scraper plate. The upper and front ends of the leaf-crushing blade are respectively provided with cutting edges. Preferably, the leaf-crushing blade has holes. Preferably, there are two hill-breaking and soil-loosening devices, respectively located on both sides behind the scraper plate, and the bottom of the scraper plate is higher in the middle and lower on both sides. Preferably, the tooth pitch of the serrations in the middle of the scraper plate is smaller than the tooth pitch of the serrations on both sides of the scraper plate.

[0010] Preferably, the scraper blade is connected to the frame or the mudguard of the coppicing device via a hinge. A positioning rod is also installed between the scraper blade and the frame or between the scraper blade and the mudguard of the coppicing device. One end of the positioning rod is hinged to the back of the scraper blade, and the other end is connected to the frame or the mudguard of the coppicing device via a spring. That is, the scraper blade can elastically swing within a certain range according to the size of the soil clods, which is beneficial for patting the soil clods and reducing the resistance of the management machine.

[0011] Preferably, the angle of inclination of the connecting plate is 15°-30°. Preferably, the angle of inclination of the connecting plate is about 20°. Here, the included angle is the angle between the connecting plate and the vertical plane (the plane perpendicular to the horizontal plane).

[0012] Preferably, the ridging plow is inclined downwards at an angle of 15°-30° to the horizontal plane, and the angle between the ridging plow and the connecting plate is an obtuse angle. The ridging plow includes a connector and a plow head. The connector is detachably installed to the connecting plate by bolts, and the plow head has a groove in the middle. The ridging plow is detachably connected to the connecting plate, allowing the ridging plow to be replaced as needed. The groove in the middle of the plow head reduces resistance.

[0013] Preferably, the loosening plate is inclined downwards from back to front, and the angle of inclination of the loosening plate is greater than the angle of inclination of the ridging plow but less than 90°. The bottom of the connecting plate is also inclined and flush with the loosening plate. After operation, a layer of loose soil will flow back under the soil separating plate. Here, the inclination angle refers to the angle between the soil separating plate and the horizontal plane.

[0014] Preferably, the fertilization device includes a fertilizer box, a fertilizer dispenser, a fertilizer pipe, and a fertilizer guide cylinder connected in sequence. The fertilizer guide cylinder is inclined forward from top to bottom and is located behind the connecting plate. The bottom of the fertilizer guide cylinder is fixed to the bottom of the connecting plate, and the upper part of the fertilizer guide cylinder is fixed to the middle of the connecting plate through a connecting piece. The bottom of the fertilizer guide cylinder is provided with a bottom fertilizer outlet, and the side fertilizer outlet is provided at intervals on the side of the fertilizer guide cylinder away from the connecting plate.

[0015] Preferably, anti-splash chains are provided on both sides of the rear of the coping device. Compared with existing anti-splash film setups, this offers greater flexibility and can be adapted to different terrains and management depths.

[0016] Compared with existing technologies, the present invention has the following advantages:

[0017] 1. The management machine of the present invention, by tilting the ridge-breaking and loosening device towards the coppicing device and equipping it with a serrated scraper, can effectively shorten the distance between the coppicing device and the ridge-breaking and loosening device, resulting in a smaller and more compact overall structure. This reduces the likelihood of missed areas during operation; simultaneously, the forward tilt of the ridge-breaking and loosening device also reduces resistance, improving the working efficiency of the management machine.

[0018] 2. The management machine of the present invention, by setting an inclined backward scraper between the coppicing device and the ridge-breaking and loosening device, and setting the bottom of the scraper to be serrated, facilitates the crushing of large clumps of mud turned over by the coppicing device or the ridge-breaking and loosening device, which is beneficial to the germination and growth of ratooned sugarcane. The scraper is hinged to the frame or the mudguard of the coppicing device and can elastically swing within a certain range according to the size of the soil clumps, which is beneficial for patting the soil clumps and reducing the resistance of the management machine.

[0019] 3. The management machine of the present invention has ridge-breaking and stubble-loosening devices set on both sides behind the scraper, and the bottom of the scraper is set as a serrated shape with a high center and low sides. After operation, the mud layer in the middle of the sugarcane planting ridge is higher, which can overcome the problem of forming craters due to less soil in the middle of the sugarcane row when cultivating and hilling in the later stage. It is especially suitable for the management of ratoon sugarcane in the wide and narrow row planting pattern.

[0020] 4. The management machine of the present invention has a leaf-chopping knife at the front end of the scraper plate. The position of the leaf-chopping knife corresponds to the position of the connecting plate and is located above the ridge-breaking plow. The leaf-chopping knife can further cut the sugarcane leaves on the ground of the ratoon sugarcane, prevent the sugarcane leaves from tangling and piling up, which would affect the management of the ratoon sugarcane, thereby improving the working efficiency of the management machine.

[0021] 5. The management machine of the present invention tilts the fertilizer guide cylinder in the fertilizer application device forward and sets a bottom fertilizer outlet at the bottom of the fertilizer guide cylinder, and sets multiple side fertilizer outlets at intervals on the rear side of the fertilizer guide cylinder, which is conducive to the fertilizer being discharged from the bottom fertilizer outlet and multiple side fertilizer outlets respectively, and can realize layered fertilization.

[0030] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0031] like Figure 1-2 As shown, a multi-functional machine for managing perennial sugarcane by leveling the base, crushing leaves, breaking ridges, deep loosening, fertilizing, and managing soil includes a frame 1, a fertilizing device 2, a leveling device 3, a ridge-breaking and loosening device 4, a limiting wheel 5, a soil scraper 6, and a leaf-crushing knife 7.

[0032] The front end of the frame 1 is provided with a connecting part 101. The frame 1 is used to install the fertilizer application device 2, the coppicing device 3, the ridge breaking and loosening device 4 and the limiting wheel 5, and is connected to the tractor through the connecting part 101 to drive the operation of each device.

[0033] The coppicing device 3 includes a power-driven rotating shaft 31 and coppicing blades 32 spaced on the rotating shaft 31, used to crush sugarcane leaves and weeds, transport topsoil, and remove the upper part of the sugarcane stump.

[0034] The ridge-breaking and soil-loosening device 4 has two sets, which are respectively located on the lower sides of the frame 1. The ridge-breaking and soil-loosening device 4 includes a ridge-breaking plow 41, a soil-loosening plate 42 and a connecting plate 43, which are used to break the ridges and transport the soil.

[0035] The limiting wheel 5 is used to adjust the soil penetration depth of the coppicing device 3 and the ridge-breaking and loosening device 4;

[0036] The scraper 6 is located between the coppicing device 3 and the ridge-breaking and stubble-loosening device 4, and is used to crush the large clumps of mud turned out by the coppicing device 3 or the ridge-breaking and stubble-loosening device 4.

[0037] The leaf-crushing blade 7 is located at the front end of the scraper plate 6, corresponding to the position of the connecting plate 43, and is positioned above the ridge-breaking plow 41, for cutting sugarcane leaves on the ground of the perennial sugarcane.

[0038] The integrated machine for leveling, leaf breaking, ridge breaking, deep loosening, fertilization, and management of Honshuku sugarcane features a forward-tilted ridge breaking and loosening device 4, a serrated scraper 6 on the leveling device 3 and the ridge breaking and loosening device 4, and a leaf-breaking knife 7 at the front end of the scraper 6. The overall structure is compact, with low operating resistance, high efficiency, and less chance of missing any work during operation.

[0039] Combination Figure 3 The bottom of the scraper blade 6 is higher in the middle and lower on both sides. The tooth spacing of the serrations in the middle of the scraper blade 6 is smaller than that of the serrations on both sides. After the operation, the soil layer in the middle of the sugarcane planting ridge is higher, which can overcome the problem of forming crater-like depressions due to less soil in the middle of the sugarcane row during later cultivation and hilling, and is especially suitable for the management of ratoon sugarcane in wide and narrow row planting patterns. Figure 4The scraper blade 6 and the mudguard 33 of the coppicing device 3 are connected by a hinge 8. A positioning rod 9 is also installed between the scraper blade 6 and the mudguard 33 of the coppicing device 3. One end of the positioning rod 9 is hinged to the back of the scraper blade 6, and the other end is connected to the mudguard 33 of the coppicing device 3 via a spring 10. Specifically, the positioning rod 9 has screw holes spaced apart. A mounting base with mounting holes is welded to the back of the scraper blade 6. The positioning rod 9 has through holes spaced apart. Bolts pass through the through holes and mounting holes to movably connect the positioning rod 9 to the mounting base. That is, the diameter of the bolt is smaller than the diameter of the through holes and mounting holes, allowing the positioning rod 9 to rotate relative to the mounting base. One end of the spring is sleeved on the lower outer side of the positioning rod 9, and the other end extends above the positioning rod 9 and connects to the mudguard 33 of the coppicing device 3. The spring provides the mudguard 33 with a certain degree of elasticity, which can adapt to different mud block sizes and reduce the overall resistance of the integrated management machine. The scraper 6 is hinged to the mudguard 33 of the leveling device 3, and can swing elastically within a certain range according to the size of the soil clods. This is also beneficial for patting the soil clods and reducing the resistance of the management machine.

[0040] Continue to combine Figure 3 Two leaf-crushing blades 7 are respectively located on both sides in front of the scraper plate 6, corresponding to the position of the hill-breaking and loosening device 4. In this embodiment, the leaf-crushing blades 7 are square and are arranged at an angle with the scraper plate 6. The upper end and front end of the leaf-crushing blades 7 are respectively provided with blades. Preferably, the leaf-crushing blades 7 are provided with holes at intervals to reduce resistance.

[0041] Combination Figure 5The ridging and loosening device 4 includes a ridging plow 41, a loosening plate 42, and a connecting plate 43. The connecting plate 43 is inclined forward at an angle of 20°. Compared to a vertically positioned connecting plate 43, the loosening plate 42 at the bottom of the connecting plate 43 can be closer to the coppicing device 3, which can shorten the distance between the coppicing device 3 and the ridging and loosening device 4, reduce missed work, and reduce operating resistance. Furthermore, the ridging plow 41 is inclined downwards at an angle of approximately 20° to the horizontal plane, and the angle between the ridging plow 41 and the connecting plate 43 is an obtuse angle. The ridging plow 41 includes a connector and a plow head. The connector is detachably installed to the connecting plate 43 by bolts, and the plow head has a groove in the middle. Specifically, the connector is a hollow square shape with mounting screw holes. The connecting rod has an inclined mounting slot, and the connector is inserted into the mounting slot and fixed to the connecting plate 43 by horizontal screws. The ridging plow 41 is detachably connected to the connecting plate 43, allowing the plow 41 to be replaced as needed. The plow head has a groove in the middle to reduce resistance. Furthermore, the loosening plate 42 is inclined downwards from back to front, with an angle greater than that of the ridging plow 41 but less than 90°. The bottom of the connecting plate 43 is also inclined and flush with the loosening plate 42. That is, the bottom of the loosening plate 42 is higher than the ridging plow 41 and inclined upwards from front to back. After operation, a layer of loose soil will flow back under the loosening plate.

[0042] Combination Figure 1-2 The fertilization device 2 includes a fertilizer box 21, a fertilizer dispenser 22, a fertilizer pipe 23, and a fertilizer guide cylinder 24 connected in sequence. The fertilizer dispenser 22 is a spiral fertilizer dispenser 22, with fertilizer outlets on both sides, meaning the fertilizer dispenser 22 simultaneously discharges fertilizer from both sides. The upper end of the fertilizer pipe 23 is connected to the fertilizer outlet of the spiral fertilizer dispenser 22 via a fertilizer receiver, and the bottom of the fertilizer pipe 23 is connected to the fertilizer guide cylinder 24. Figure 6 The fertilizer guide cylinder 24 is inclined forward from top to bottom and is located behind the connecting plate 43. The bottom of the fertilizer guide cylinder 24 is welded and fixed to the bottom of the connecting plate 43, and the upper part of the fertilizer guide cylinder 24 is fixed to the middle of the connecting plate 43 through a connecting piece. That is, the inclination angle of the fertilizer guide cylinder 24 is greater than the inclination angle of the connecting plate 43. The bottom of the fertilizer guide cylinder 24 is provided with a bottom fertilizer outlet 241, and the side fertilizer outlets 242 are spaced apart on the side of the fertilizer guide cylinder 24 away from the connecting plate 43. By inclining the fertilizer guide cylinder 24 in the fertilization device 2 forward and providing a bottom fertilizer outlet 241 at the bottom of the fertilizer guide cylinder 24, and providing multiple side fertilizer outlets 242 spaced apart on the rear side of the fertilizer guide cylinder 24, it is beneficial for fertilizer to be discharged separately from the bottom fertilizer outlet 241 and multiple side fertilizer outlets 242, which can realize layered fertilization and prevent soil from clogging the fertilizer guide cylinder 24.

[0043] Furthermore, the coppicing device 3 can be an existing coppicing device 3 for ratoon sugarcane management machines, including a power-driven rotating shaft 31 and coppicing blades 32 spaced apart on the rotating shaft 31, with mudguards 33 provided on the outer side of the coppicing blades 32. Anti-splash chains 11 are respectively provided on both sides of the rear of the coppicing device 3. Compared with existing anti-splash film installations, the anti-splash chains 11 offer greater flexibility and can be adapted to different terrains and management depths.

[0044] Specifically, in this application, the forward direction of the integrated management machine during operation is forward, and other directions are based on this. Any aspects not described in this application can be implemented using existing technology.

[0045] After the previous year's sugarcane harvest, a multi-functional management machine for ratoon sugarcane, including stubble leveling, leaf breaking, ridging, deep loosening, and fertilization, can be used for management. The machine is connected to a tractor via connector 101, and the tractor pulls the machine for operation. This machine can simultaneously perform stubble leveling, shoveling, leaf breaking, soil loosening, and fertilization on ratoon sugarcane. Among them, the coppicing device 3 can be adjusted to a working depth of 5-8cm, which can not only crush sugarcane leaves and weeds and loosen the top soil, but also remove the upper part of the sugarcane stubble to promote the germination of the sugarcane stubble; the leaf crusher 7 further cuts the sugarcane leaves to prevent them from getting tangled in the ridge breaking and stubble loosening device 4; the ridge breaking and stubble loosening device 4, combined with the coppicing device 3 and the soil scraping device, can crush the soil of the ratoon sugarcane; the working depth of the ridge breaking and stubble loosening device 4 is 30-40cm, and the fertilizer guide cylinder 24 of the fertilizer application device 2 is set at an angle and is equipped with a bottom fertilizer outlet and multiple side fertilizer outlets 242, which can realize layered fertilization.

[0046] In summary, the integrated machine for leveling, leaf breaking, ridging, deep loosening, fertilizing, and managing ratoon sugarcane effectively shortens the distance between the ridging and loosening device 4 and the coppicing device 3 by tilting the device 4 towards the coppicing device 3. This results in a more compact and smaller overall structure, reducing the likelihood of missed areas during operation. The forward tilt of the coppicing and loosening device 4 also reduces resistance and improves the machine's efficiency. Furthermore, the serrated scraper 6, equipped with a leaf-crushing blade 7, positioned between the coppicing device 3 and the coppicing and loosening device 4, effectively shreds the sugarcane leaves and breaks up large clumps of soil turned over by the coppicing device 3 or the coppicing and loosening device 4, promoting the germination and growth of ratoon sugarcane.

[0047] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
