[0002] The corn spring furrowing and mulching sowing device is an integrated agricultural machinery equipment designed specifically for spring corn planting. It integrates functions such as furrowing, sowing, mulching, and pressing, which can greatly improve corn planting efficiency and meet the needs of spring soil moisture management.

[0003] In large-scale farms and planting cooperatives in major corn-producing areas such as the Huang-Huai-Hai Plain, these areas have large arable land areas and tight farming seasons in spring. The sowing devices can be pulled by tractors to achieve high-speed operation. At the same time, they can be adapted to the standardized row spacing requirements of large-scale planting, which facilitates the coordinated operation of subsequent mechanized weeding, fertilization, harvesting and other links.

[0017] During sowing, the adjustment structure by adjusting the connection position between the drive wheel 12 and the fixed connecting frame 11 is existing technology and will not be described in detail here. It can adapt to the operational needs of different terrains. Under the power drive of the drive wheel 12, the power drive is provided by existing equipment such as a tractor, which will not be described in detail here. The supporting frame 1 drives multiple sets of detachable furrowing components 2, the sowing components 3 fixed by the bracket, and the film covering components 4 fixed to the end of the supporting frame 1 away from the furrowing components 2 to move synchronously, realizing a continuous operation process of furrowing, sowing, and film covering. At the same time, the soil is broken up before furrowing, which can reduce the resistance during furrowing and improve the furrowing effect.

[0018] Reference Figure 2 and Figure 3 The trenching component 2 includes a connecting protrusion 21, which is slidably disposed on the outside of the bearing frame 1. Several fixing members A22 are rotatably disposed on the inside of the connecting protrusion 21 for fixing the connecting protrusion 21 to the bearing frame 1. A connecting plate 23 is fixedly disposed at the bottom of the connecting protrusion 21. A disc 24 is symmetrically fixedly disposed on the outside of the connecting plate 23. A soil-breaking plate 25 is detachably disposed on the outside of the connecting plate 23. A fixing member B26 is threaded on the inside of the soil-breaking plate 25. Several adjusting holes 27 are opened on the outside of the connecting plate 23 corresponding to the fixing member B26. The fixing members B26 are threaded on the inside of the adjusting holes 27.

[0019] During trenching operations, when adjusting the breaking depth according to different soil hardness or corn varieties, the fixing part B26 can be unscrewed, the breaking plate 25 can be adjusted to a suitable height, the fixing part B26 can be aligned with the corresponding adjustment hole 27 and tightened, so as to achieve flexible adjustment of the position of the breaking plate 25. In subsequent operations, planting trenches of appropriate depth are opened through each set of discs 24 to adapt to the trenching needs of different soil textures such as sandy loam and clay loam, forming trenches that meet the requirements for corn sowing.

[0020] Reference Figure 1 and Figure 3The sowing component 3 includes a seed box 31. A seed lowering box 32 is fixedly installed on the outside of the seed box 31 corresponding to each group of furrowing components 2.

The seed lowering pipe 37 is connected to the bottom pipe of the corresponding seed lowering box 32, and the fertilizer application pipe 38 is connected to the bottom pipe of the fertilizer collection box 34.

[0021] During sowing, the seed box 31 is connected to the seed distribution box 32 fixed on the outside of each group of furrowing components 2 through the discharge port. The seeds are transported quantitatively through the seed distribution disc 33, which is rotated inside the seed distribution box 32. At the same time, the rotating shaft fixed inside the seed distribution disc 33 is powered by an external drive device. When the seed distribution disc 33 rotates, the seeds in the seed distribution box 31 are transported to the seed distribution pipe 37 through the discharge port. Then, the seed distribution pipe 37 sows the seeds into the furrow formed by the furrowing components 2. Meanwhile, the fertilizer collection box 34 is connected to the fertilizer application pipe 38 through the pipe. The fertilizer is transported into the furrow through the fertilizer application pipe 38, so that sowing and fertilization are carried out simultaneously.

[0022] Reference Figure 4 An electric push rod 39 is fixedly installed on the outside of the seed box 31. A drive rod 301 is installed at the output end of the electric push rod 39. A collection frame 302 is fixedly installed at the bottom of the drive rod 301. A bonding plate 303 is fixedly installed at the bottom of the collection frame 302 corresponding to the seed box 32. The bonding plate 303 is slidably installed on the inside of the seed box 32. A brush 304 is fixedly installed on the inside of the bonding plate 303 for spreading and cleaning the seeds at the outlet.

[0023] During the sowing process, the electric push rod 39 drives the drive rod 301 to move up and down, which in turn causes the collection frame 302 and the bonding plate 303 to slide inside the seed box 32. The brush 304 then cleans the seeds at the discharge port to prevent the seeds from clogging the discharge port.

[0024] Reference Figure 4The film covering assembly 4 includes a support plate 41. Connecting frames A42 are symmetrically arranged on the outer side of the support plate 41. Film rolls 43 are rotatably arranged on the inner side of the connecting frames A42 on both sides. Connecting frames B44 are symmetrically arranged at the bottom of the support plate 41, located between the disc 24 and the film rolls 43. Fixed rods are rotatably arranged on the inner side of the connecting frames B44 on both sides. Several pressing rollers 45 are coaxially fixed on the outer side of the fixed rods. Every two pressing rollers 45 are arranged as a group on both sides of the disc 24. A soil covering plate 46 is fixedly arranged at the bottom of the support plate 41, located between the disc 24 and the pressing rollers 45.

[0025] During sowing, the plastic film is wound onto the plastic film roll 43. As the device moves, the plastic film unfolds from the plastic film roll 43 and covers the trench formed by the trenching component 2. At the same time, every two pressing rollers 45 are set on both sides of the disc 24. The pressing rollers 45 roll during the movement of the device to compact the edge of the plastic film. Then, the soil covering plate 46 scrapes the soil on both sides of the trench to the edge of the plastic film to further fix the plastic film. After the plastic film is covered and compacted in the same stage, the laser perforator 47 is activated to punch holes in the plastic film at the corresponding position in the middle of each group of pressing rollers 45, providing a channel for the subsequent germination and emergence of corn seeds. Several laser perforators 47 are fixedly installed on the top surface of the support plate 41, and the output end of the laser perforator 47 is set at the middle position of each group of pressing rollers 45.

[0026] In summary, the corn spring furrowing, mulching, and sowing device disclosed in this application, when in use, uses an existing technology to adjust the connection position between the drive wheel 12 and the fixed connecting frame 11 during sowing, which will not be elaborated here. This allows it to adapt to different terrain requirements. The drive wheel 12 provides the power, which is provided by existing equipment such as a tractor, and will not be elaborated here either. The supporting frame 1 drives multiple detachable furrowing components 2, the sowing components 3 fixed by brackets, and the mulching components 4 fixed to the end of the supporting frame 1 away from the furrowing components 2 to move synchronously, realizing a continuous operation process of furrowing, sowing, and mulching. Simultaneously, before furrowing... Breaking up the soil reduces resistance during ditching and improves ditching efficiency. During ditching, to adjust the breaking depth according to different soil hardness or corn varieties, the fixing piece B26 can be unscrewed, and the breaking plate 25 adjusted to a suitable height. The fixing piece B26 is then aligned with the corresponding adjustment hole 27 and tightened, allowing for flexible adjustment of the breaking plate 25's position. In subsequent operations, planting trenches of appropriate depth are created using each set of discs 24 to adapt to different soil textures such as sandy loam and clay loam, forming trenches suitable for corn planting. During planting, the seed box 31 is connected to the seed box 32 fixed to each set of ditching components 2 via the discharge port. Seeds are quantitatively delivered via a rotating seeding disc 33 inside the seed box 32. Simultaneously, a fixed rotating shaft inside the seeding disc 33 is powered by an external drive device. As the seeding disc 33 rotates, it delivers seeds from the seed box 31 through the discharge port to the seeding pipe 37, which then sows the seeds into the trenches formed by the furrowing assembly 2. Simultaneously, the fertilizer collection box 34 is connected to the fertilizer application pipe 38 via a pipe, delivering fertilizer into the trenches, thus achieving simultaneous sowing and fertilization. During sowing, an electric push rod 39 drives a drive rod 301 to move up and down, which in turn causes the collection frame 302 and the bonding plate 303 to slide inside the seed box 32. The brush 304... The seeds at the discharge port are then cleaned to prevent them from clogging the discharge port. During sowing, the mulch film is wound onto the mulch film roll 43. As the device moves, the mulch film unfolds from the mulch film roll 43 and covers the trench formed by the trenching component 2. At the same time, every two pressing rollers 45 are set on both sides of the disc 24. The pressing rollers 45 roll during the movement of the device to compact the edge of the mulch film. Then, the soil covering plate 46 scrapes the soil on both sides of the trench to the edge of the mulch film to further fix the mulch film. After the mulch film is covered and compacted in the same stage, the laser perforator 47 is activated to punch holes in the mulch film position corresponding to the middle of each group of pressing rollers 45, providing a channel for the subsequent germination and emergence of corn seeds.
