Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0025] like Figs. 1-2The rice-oilseed rotation mechanized device shown includes a platform 1, which consists of an upper platform 2 and a lower platform 3. A gap is left between the upper platform 2 and the lower platform 3, and a seedling tray conveying mechanism is arranged in the gap. Several driving components 4 are installed at the bottom of the lower platform 3. Track mechanisms connected to the driving components 4 are arranged on both sides of the platform 1. A first support frame 5 extending outward is arranged on the upstream side of the seedling tray conveying mechanism of the platform 1. A rice planting module is installed on the first support frame 5. A rapeseed planting module is installed on the downstream side of the platform 1. A second support frame 6 is connected to the outside of the rapeseed planting module. A combine harvesting module is installed on the second support frame 6.

[0026] The equipment platform 1 is also provided with threshing mechanisms 7 on both sides, and a crop conveying mechanism 8 is connected between the threshing mechanism 7 and the end of the combine harvester module.

[0027] A control box 9 and a plant protection platform 10 are installed on the top of the equipment platform 1, and a monitoring component is installed on the top of the control box 9.

[0028] Based on the above, the layered structure of the upper platform 2 and the lower platform 3 provides installation space for each module. The seedling tray conveying mechanism in the gap realizes the transfer of seedling trays from upstream to downstream. The drive component 4 drives the equipment to move through the track mechanism. The rice / rapeseed modules are located on both sides of the seedling tray conveying mechanism to realize the continuity of the planting process. The combined harvesting module is connected to the threshing mechanism 7 through the crop conveying mechanism 8 to form a "harvesting-threshing" production line.

[0029] Furthermore, the functional modules are arranged in a compact and orderly manner, reducing the size of the equipment and facilitating field operations. The seedling tray conveying and planting modules are linked, and harvesting and threshing are directly connected, improving operational efficiency. The tracked mechanism enhances the equipment's passability in paddy fields and dry land, preventing wheeled machinery from slipping.

[0030] The drive unit 4 includes a drive box 11 fixed to the bottom of the lower platform 3 and an engine 12 installed inside the drive box 11. The output shaft of the engine 12 extends to the outside of the drive box 11. The track mechanism includes a plurality of drive gears 13 located on the outside of the equipment platform 1. A transmission track 14 is sleeved on the outside of the drive gears 13 located on the same side. The end of the output shaft of the engine 12 is connected to the drive gears 13.

[0031] Based on the above, the engine 12 drives the drive gear 13 to rotate through the output shaft, which in turn drives the outer transmission track 14 to rotate, thus enabling the equipment to move. The two tracks are driven independently and can be turned by the speed difference, with a turning radius of ≤2.5m.

[0032] Furthermore, the engine 12 is a direct-drive track with strong driving force, adapting to complex terrain. The transmission track 14 is a rubber track, which increases the ground contact area and reduces damage to the soil. The tracked steering system improves field mobility and is suitable for small plots of land.

[0033] The first support frame 5 includes two first connecting rods 15 fixedly connected to the edge of the upper platform 2 and a horizontal plate 16 fixed to the end of the first connecting rods 15. The horizontal plate 16 has a through mounting groove 17.

[0034] The rice planting module is located in the installation groove 17. The rice planting module includes a seed tank 18 fixed in the installation groove 17. The bottom end of the seed tank 18 is connected to a feeding pipe 19. A valve 20 for controlling the on-off state is installed on the feeding pipe 19.

[0035] Based on the above, the first support frame 5 is fixed to the upper platform 2 through the first connecting rod 15, the horizontal plate 16 mounting groove 17 provides a detachable interface for the rice planting module, the seed tank 18 stores rice seeds, and the start and stop of sowing is controlled by the valve 20 at the outlet of the feed pipe 19, so as to realize the quantitative release of seeds in the direct seeding mode.

[0036] Furthermore, the planting module can be quickly installed and removed via the mounting slot 17 for easy maintenance or replacement. The valve 20 can be manually or electrically controlled to flexibly adjust the sowing timing and avoid waste. The support frame is rigidly connected to the platform to reduce shaking during operation.

[0037] The upper platform 2 has a seedling tray groove 21 on the side away from the first support frame 5. The seedling tray groove 21 is located directly above the end of the sample conveying mechanism. The other end of the sample conveying mechanism extends between the two first connecting rods 15.

[0038] The seedling tray conveying mechanism includes two profile frames 22 on the left and right and a first connecting rod 15 connected between the two profile frames 22. The two profile frames 22 are fixed on the surface of the lower platform 3. There are several first connecting rods 15. A seedling tray conveyor belt 24 is sleeved between the several first connecting rods 15. A first motor that drives the seedling tray conveyor belt 24 to rotate is installed on the outer wall of the profile frame 22.

[0039] Several vertical scrapers 25 are installed at the bottom of the profile frame 22 to ditch, rotary till, or turn the soil during the movement of the equipment.

[0040] Based on the above, the seedling tray is placed into the seedling tray trough 21, and the seedling tray conveyor belt 24 (rotating around the first connecting rod 15) driven by the first motor transports the seedling tray to the transplanting position below the first support frame 5. The seedling tray transport is linked with the sowing module to achieve seamless connection between "sowing and transplanting" and adapt to the transplanting density requirements of different crops or varieties.

[0041] The rapeseed planting module includes a first support plate 26 fixed at the edges of the lower platform 3 and the upper platform 2, and several air-suction seed metering devices 27 are fixedly installed on the outer wall of the first support plate 26.

[0042] Based on the above, the air suction seed metering device 27 uses negative pressure to adsorb rapeseed seeds and discharges them evenly at a set interval to achieve precision direct seeding. The first support plate 26 is fixed to the edge of the upper and lower platforms 3 to provide a stable installation foundation for the seed metering device.

[0043] Furthermore, the air suction principle avoids seed accumulation or missed sowing, and the uniformity is better than traditional mechanical sowing. It can be changed according to rapeseed varieties and adapts to different seed sizes. It is integrated on the side of the equipment, does not occupy the central space, and maintains the center of gravity balance.

[0044] The second support frame 6 includes a second connecting rod 28 fixed at both sides of the first support plate 26, and an outer plate 29 is installed at the end of the second connecting rod 28. The combined harvesting module is installed on the outer plate 29.

[0045] The combined harvesting module includes an arc-shaped baffle 30 fixed on the outer plate 29 and a harvesting roller 31 located inside the arc-shaped baffle 30. The harvesting roller 31 includes a rotating roller shaft 33 and a conveying blade 32 installed on the outer wall of the roller shaft 33. A harvesting rod 34 is provided on the outer side of the conveying blade 32. There is a gap between the two ends of the arc-shaped baffle 30 and the two ends of the harvesting roller 31.

[0046] Based on the above, the second support frame 6 is connected to the rapeseed planting module through the second connecting rod 28, the outer plate 29 provides support for the harvesting drum 31, the roller shaft 33 drives the conveying blades 32 and the harvesting rod 34 to rotate, cutting the crop and continuously cutting the crop by rotating the harvesting rod 34, and in conjunction with the conveying blades 32, batches are conveyed to the gap between the arc baffle 30 and the drum, and picked up by the crop conveying mechanism 8.

[0047] Furthermore, the conveying blades 32 are arranged in two symmetrical sections with different directions. When the conveying blades 32 rotate, they can convey crops in batches to the gaps on both sides.

[0048] Among them, the arc-shaped baffle 30 prevents crops from splashing and guides the crops to move towards the conveying mechanism. The harvesting module and the rapeseed planting module share the same support frame, reducing redundant structures.

[0049] The crop conveying mechanism 8 includes an inclined crop conveyor belt 35, the bottom of which is connected to the gap between the arc-shaped baffle 30 and the two ends of the harvesting drum 31, and the top of which is connected to the threshing mechanism 7.

[0050] The monitoring components include a pole 36 fixed to the top of the control box 9 and a monitoring lens 37 and a microwave radar 38 mounted on the pole 36. The threshing mechanism 7 includes a second support plate 39 fixed to the two sides of the upper platform 2 and a threshing roller 40 mounted on the second support plate 39. The inner end of the threshing roller 40 is connected to a discharge trough plate 41, which extends to the surface of the plant protection platform 10.

[0051] Based on the above, the crop conveyor belt 35 is inclined, and the harvested crops are transported to the threshing drum 40 by gravity and the movement of the conveyor belt. When the threshing drum 40 rotates, the crops are impacted by the internal structure, so that the grains are separated from the straw. The grains fall into the plant protection platform 10 through the discharge trough plate 41.

[0052] Furthermore, the monitoring camera 37 captures real-time footage of the operation, the microwave radar 38 monitors crop density or equipment operating status, and the data is transmitted to the control box 9. After receiving the signal, the control box 9 adjusts parameters such as seeding rate and conveyor belt speed through actuators such as valves 20 and motors.

[0053] Based on the above, this utility model, through "multi-functional integration + intelligent control + lightweight design", covers the entire process of "planting-management-harvesting" in rice-oilseed rotation, eliminating the need for frequent replacement of agricultural machinery, reducing purchase costs by 50%-60%, realizing full mechanization of rice-oilseed rotation, solving the problems of single function and low efficiency of traditional machinery, and providing efficient equipment support for year-round high yields of grain and oilseeds in the Yangtze River Basin.

[0054] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
