It boasts high efficiency and quality. Moreover, it can simultaneously plant two rows of sugarcane and perform film covering operations on both rows in one operation. This significantly improves film covering efficiency, reduces labor and machinery wear and tear, and the wide film covering effectively reduces film overlap gaps, enhances surface sealing, and improves moisture retention, heat preservation, weed suppression, and windbreak and soil stabilization effects, which are beneficial to the early growth of sugarcane. Furthermore, through the action of the film covering disc plow, soil can be covered on both sides of the film, and some soil can be transported to the middle of the film through the spiral blades in the film pressing wheel tube, improving the soil covering effect.

Detailed Implementation

[0027] 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.

[0028] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0029] like Figures 1 to 5As shown, a double-row, fully-film-covered sugarcane planter according to a specific embodiment of the present invention includes a frame 6, two row-dividing mechanisms 8, a fertilization mechanism, two soil-covering mechanisms, and a soil-covering and film-covering mechanism. The front end of the frame 6 is equipped with a three-point suspension mechanism connected to a traveling mechanism, which drives the sugarcane planter to move and operate in the field. The two row-dividing mechanisms 8 are symmetrically installed at the bottom of the frame 6 for digging planting trenches; they can dig two planting trenches at once, thus planting two rows of sugarcane simultaneously. Two seed-distributing mechanisms 3 are symmetrically installed on the frame 6, each corresponding to one of the row-dividing mechanisms 8. Each seed-distributing mechanism 3 is used to distribute sugarcane seeds one by one into the corresponding planting trench for planting sugarcane. The fertilization mechanism is installed on the frame 6 for applying fertilizer into the planting trenches. The two soil-covering mechanisms are symmetrically installed at the bottom of the frame 6, each corresponding to one of the row-dividing mechanisms 8. Each soil-covering mechanism is installed behind the corresponding row-dividing mechanism 8 for covering the planting trenches with soil. The soil covering and film covering mechanism is installed on the rear side of the frame 6 and behind the two soil covering mechanisms, and is used for covering the film and covering the soil. The soil covering and film covering mechanism includes a film covering support 14, a film rod 20, two film covering disc plows 22, and two film pressing wheel tubes 21. The upper end of the film covering support 14 is hinged to the rear side of the frame 6 in a way that allows it to swing back and forth, and the film covering support 14 is driven to swing back and forth by a swing mechanism 17. The swing mechanism 17 is a hydraulic cylinder, which is hinged between the film covering support 14 and the frame 6. During operation, the film covering support 14 is driven to swing forward, so that the rear film rod 20, the two film covering disc plows 22, and the two film pressing wheel tubes 21 contact the ground to carry out the film covering work; when not in operation, the film covering support 14 is driven to swing backward, raising the rear film rod 20, the two film covering disc plows 22, and the two film pressing wheel tubes 21, facilitating movement and turning. The film rod 20 is detachably installed below the film covering support 14 for mounting the film roll. Two film covering disc plows 22 are symmetrically installed on the film covering support 14 and located behind the film rod 20. Each film covering disc plow 22 is rotatably connected to the film covering support 14, and the two film covering disc plows 22 are located on the left and right sides of the film covering and distributed in a figure-eight shape with the opening facing forward. When the frame 6 moves forward, it can drive the film covering disc plows 22 to rotate and cover the soil, covering the left and right sides of the film covering the film covering. The film pressing wheel tube 21 corresponds one-to-one with the film covering disc plow 22. Each film pressing wheel tube 21 is rotatably installed on the film covering support 14 and located inside the corresponding film covering disc plow 22. The film pressing wheel tube 21 is located above the film covering and presses the film covering as it rolls. The axis of each film pressing wheel tube 21 is distributed in the left and right direction, and each film pressing wheel tube 21 is provided with an inward conveying spiral blade 16. The soil covered by the mulching disc plow 22 is divided into two parts. One part covers the edge of the mulch film, and the other part is transported to the pressing roller tube 21 and then transported to the middle of the mulch film by the spiral blades 16 inside the pressing roller tube 21. This improves the soil covering effect, ensures good adhesion of the mulch film, reduces the risk of damage, and enhances the moisture retention and wind protection effects.The sugarcane planting machine of this invention integrates ditching, sowing, fertilization, soil covering, mulching, and pressing, enabling the sugarcane planting operation to be completed in one go. It has high work efficiency and good quality. Moreover, it can plant two rows of sugarcane simultaneously in one operation and perform mulching on both rows of sugarcane. While significantly improving mulching efficiency and reducing labor and machinery wear and tear, the wide film covering can effectively reduce the gaps between the film overlaps, enhance the surface sealing, and improve the effects of moisture retention, heat preservation, weed suppression, and windbreak and soil stabilization, which is beneficial to the early growth of sugarcane.

[0030] refer to Figure 1 , Figure 2 and Figure 3 The row-dividing mechanism 8 can be a structure of a furrowing plow 26, or a structure of a furrowing plow 26 and two retaining plates 27. Preferably, each row-dividing mechanism 8 includes a furrowing plow 26, two retaining plates 27, and two adjusting plates 7. The two retaining plates 27 are symmetrically arranged on the left and right sides and installed on the rear side of the furrowing plow 26. The furrowing plow 26 is used to dig planting furrows, and the retaining plates 27 can prevent the soil on both sides of the planting furrow from closing up, facilitating the planting of sugarcane. The two adjusting plates 7 are symmetrically installed on the outer sides of the two retaining plates 27. The front end of each adjusting plate 7 is hinged to the outer wall of the corresponding retaining plate 27, and the angle of the adjusting plate 7 can be adjusted. That is, the adjusting plate 7 is inclined outward from front to back, and the opening of the adjusting plate 7 can be adjusted, thereby adjusting the amount of soil returned. The larger the angle of the adjusting plate 7, the more the soil can be pushed to both sides, and the less soil falls back; conversely, the more soil falls back, which can adapt to different land conditions and planting patterns. An adjusting rod 28 can be installed between the rear side of the adjusting plate 7 and the outer side of the retaining plate 27. The outer end of the adjusting rod 28 is hinged to the rear side of the adjusting plate 7, and the inner end of the adjusting rod 28 has a connecting hole. The outer side of the retaining plate 27 has a connecting plate 29. The connecting rod has multiple first connecting holes spaced apart in the front-rear direction. One of the first connecting holes can be selected to connect with the connecting hole of the adjusting rod 28 as needed, making angle adjustment convenient. The top surface of the branching mechanism is connected to the frame through a mounting base.

[0031] refer to Figures 1 to 3The seed metering mechanism 3 can be a structure of a seed box and a seed metering roller, or a structure of a seed conveyor belt 23 and a seed guide trough 25. Preferably, each seed metering mechanism 3 includes a seed conveyor belt 23 and a seed guide trough 25, both of which are mounted on the frame 6. The seed conveyor belt 23 is driven to rotate by a seed drive mechanism. The seed drive mechanism is a hydraulic motor 13, used to drive the seed conveyor belt 23 to rotate forward; and the hydraulic motor adjusts its speed through a hydraulic speed regulating valve 5, thereby controlling the seeding speed of the seed conveyor belt 23. Multiple evenly distributed seed troughs are provided along the length of the seed conveyor belt 23, each seed trough capable of holding one seed, allowing the seed to be discharged one seed at a time. The sugarcane guide trough 25 is installed in front of the sugarcane seed conveyor belt 23, and is inclined downwards from front to back. The lower end of the sugarcane guide trough 25 is located on the planting ditch, that is, the lower end of the sugarcane guide trough 25 is located between two retaining plates 27, so as to transport the sugarcane seeds into the planting ditch. During operation, the sugarcane seed conveyor belt 23 transports the sugarcane seeds one by one to the top of the sugarcane guide trough 25, and the sugarcane seeds fall into the planting ditch along the sugarcane guide trough 25. Each sugarcane seed conveyor belt 23 is provided with a sugarcane box 24 at the rear. The sugarcane seeds in the sugarcane box 24 can be raked one by one into the sugarcane seed trough of the sugarcane seed conveyor belt 23 by a sugarcane rake mechanism, or the sugarcane seeds in the sugarcane box 24 can be placed one by one into the sugarcane seed trough of the sugarcane seed conveyor belt 23 manually.

[0032] refer to Figures 1 to 3 ,and Figure 5The fertilization mechanism can be a structure consisting of a conveying auger and a fertilizer box, or a structure consisting of a fertilization turntable 10 and a fertilizer box 1. Preferably, the fertilization mechanism includes a fertilization support 2, a fertilizer box 1, a reducer 12, a fertilization turntable 10, two scrapers 9, and two fertilizer outlets 11. The fertilization support 2 is installed on the top of the frame 6. The fertilizer box 1 is installed on the fertilization support 2, and the bottom of the fertilizer box 1 has a discharge port for easy fertilizer discharge. The reducer 12 is installed on the frame 6 and located below the fertilizer box 1. The middle part of the fertilization turntable 10 is connected to the output shaft of the reducer 12, and the reducer 12 drives the fertilization turntable 10 to rotate and apply fertilizer. The reducer 12 can be driven by a separate hydraulic motor; or, the reducer 12 can be connected to the rotating shaft of the sugarcane seed conveyor belt 23 through a transmission mechanism, transmitting the rotational power of the sugarcane seed conveyor belt 23 to the reducer 12, thereby driving the fertilization turntable 10 to rotate and apply fertilizer. The fertilizer turntable 10 has a cone-shaped part located in the middle of the discharge port, which is smaller at the top and larger at the bottom. A discharge gap is left between the discharge port and the cone to facilitate the discharge of fertilizer into the fertilizer chamber of the fertilizer turntable 10. Multiple evenly distributed fertilizer scraping blocks are arranged on the circumferential side of the cone to prevent fertilizer from clogging the discharge gap. Two scrapers 9 are installed on the left and right sides of the fertilizer box 1 and inside the fertilizer turntable 10. The rotation of the fertilizer turntable 10 drives the fertilizer inside the turntable 10 to rotate. When the fertilizer rotates to the scraper 9, it can be scraped off by the scraper 9. Each scraper 9 is connected to the fertilizer support 2 in a height-adjustable manner, meaning that the scraper 9 can move up and down to adjust the amount of fertilizer applied; the lower the scraper 9 moves, the more fertilizer it scrapes off, and the higher the scraper 9 moves, the less fertilizer it scrapes off. This allows for adjustment of the amount of fertilizer applied as needed, making it highly practical. More preferably, the scraper 9 has elongated holes distributed along its length in the vertical direction, and is connected to the fertilizer applicator 2 by bolts through these holes. When height adjustment is needed, loosen the bolts, move the scraper 9 up and down to the desired height, and then tighten the bolts; the adjustment method is simple and convenient. Two fertilizer inlets 11 are installed on the fertilizer applicator 2 and correspond to the scraper 9, with each inlet 11 corresponding to a planting ditch. The fertilizer inlets 11 can receive the fertilizer scraped down by the scraper 9 and discharge it into the planting ditch below, completing the fertilization process.

The two covering disc plows 19 are connected to the two retaining plates 27 of the rowing mechanism via a covering support 32. The covering disc plows 19 are rotatably mounted on the covering support 32. The front end of the covering support 32 is hinged between the rear sides of the two retaining plates 27. A mounting frame 33 is provided between the upper rear sides of the two retaining plates 27, with its front end connected to the two retaining plates 27 and its front end connected to the frame 8 via a mounting seat. The rear end of the covering support 32 is connected to the rear end of the mounting frame 33 via a spring rod 30. The lower end of the spring rod 30 is connected to the rear end of the soil covering support 32, and the upper end of the spring rod 30 is hinged to the rear end of the mounting frame 33. Through the action of the spring rod, the soil covering disc plow 19 can be elastically oscillating up and down to adapt to different terrains.

[0034] refer to Figure 2 and Figure 4 Preferably, the sugarcane planter further includes two scraper blades 18, each corresponding to a soil covering mechanism. Each scraper blade 18 is located behind its corresponding soil covering mechanism and in front of the soil covering and film covering mechanism, enabling the ridges to be leveled and facilitating subsequent film covering operations. More preferably, each scraper blade 18 is connected to the soil covering mechanism's soil covering support 32 via a scraper bracket 31. The scraper blade 18 is installed at the lower end of the scraper bracket 31. The middle part of the scraper bracket 31 is hinged to the rear end of the soil covering mechanism's soil covering support 32, and the upper end of the scraper bracket 31 is connected to the front end of the soil covering mechanism's soil covering support 32 via a spring rod 30. The axis of the spring rod 30 is distributed along the front-rear direction, allowing the scraper blade 18 to elastically swing back and forth to adapt to different terrains. Among them, because the soil covering support 32 is hinged to the soil retaining plate 27, the soil covering support 32 can swing up and down elastically, while the middle part of the soil scraping support 31 is hinged to the rear end of the soil covering support 32, so that the soil scraping plate 18 can swing up and down elastically, and also swing back and forth elastically.
