Description

Technical Field

[0001] The present invention relates to the technical field of corn planting, and in particular to a sweet and sticky corn planting device and method based on early spring film covering. Background Art

[0002] Early spring mulching planting technology is an effective way to improve the yield and quality of sweet and sticky corn. Sweet and sticky corn has high temperature requirements, especially in the low temperature season in spring. It often germinates poorly or grows slowly due to the low temperature and lagging soil temperature. In order to overcome this problem, farmers usually use mulching film to cover the soil and use the greenhouse effect to increase soil temperature, promote early seed germination and root development. Mulching can not only effectively increase soil temperature, but also maintain soil moisture, reduce water evaporation, and reduce weed growth, thereby effectively increasing corn growth rate and yield. In addition, mulching can also protect corn roots from low temperature damage and improve crop resistance. In the early spring planting of sweet and sticky corn, the use of suitable film materials and reasonable film laying methods can not only increase crop yield, but also improve its growth environment, improve crop quality and market competitiveness.

[0003] A Chinese patent (publication number: CN119234527B) discloses a device for planting corn in saline-alkali soil. This device uses a dedicated planting pit excavation drill to dig a seedling pit of appropriate size in saline-alkali soil. As the planting pit excavation drill is lifted out of the seedling pit, a metered feed rod descends and rotates under the action of weight and springs, delivering a predetermined amount of nutrient soil into the pit. Simultaneously, a corn seed supply coil descends and rotates under the action of weight and springs, burying a predetermined amount of corn seeds in the pit. This achieves integrated soil improvement and sowing in saline-alkali soil, allowing for simple excavation and replacement of saline-alkali soil and quantitative planting of corn seeds. However, in actual use, this device cannot backfill the soil after sowing, requiring manual backfilling, which increases the complexity of the planting operation. Furthermore, the device cannot cover the soil after sowing, which reduces the corn germination rate and requires subsequent manual replanting. Summary of the Invention

[0014] The beneficial effects of the present invention are as follows: 1. The present invention installs the trenching block to the bottom of the device through a mounting plate and bolts, and adjusts the height of the drum through an electric telescopic rod so that the loosening rake can be immersed in the soil when following the rotation of the drum. When the device moves, the loosening rake contacts the soil and rotates, and the soil is loosened by the drum and the loosening rake. As the device continues to move, the loosened soil is at the trenching block, and the trenching block separates the soil to both sides, forming a grout in the middle, thereby achieving automatic trenching. The driving motor drives the two sets of backfill paddles to rotate in opposite directions, so that the soil on both sides of the trench follows the rotation of the backfill paddles for backfilling, thereby burying the corn seeds. When the buried soil passes through the leveling plate, the soil is leveled by the leveling plate. As the device continues to move, the film at the card plate gradually fits into the restored flat soil, and the device is reversed by the wheels. At this time, the drive motor rotates in the opposite direction, causing the two sets of backfill paddles to reverse. As the device reverses, the two sets of backfill paddles flatten the film, and the electric telescopic rod drives the loosening harrow and the roller to move vertically back and forth, so that the loosening harrow is used to punch holes in the film. The setting of this component effectively avoids the problem of manual film covering during the planting process of sweet and sticky corn, and can achieve the effect of automatic film covering and punching holes in the film, reducing the planting time and improving the corresponding planting efficiency. At the same time, the film covering operation increases the germination rate of sweet and sticky corn and saves the time for subsequent replanting.

[0015] 2. The present invention drives the rotating plate to rotate by a servo motor, so that the fixed rod rotates along the rotating plate. As the rotating plate rotates, the driven block and the sealing cover move vertically downward, so that the receiving beam moves vertically downward along the inner wall of the limit block 1, thereby driving the connecting rod, the seeding rod, the seeding block and the bottom plate to move vertically downward, so that the quantitative corn seeds at the seeding block move to the seeding port. When the seeding block is separated from the inside of the base, the corn seeds fall into the previous groove by their own gravity. At this time, the seeding rod is inserted into the inside of the seeding port, thereby preventing a large number of corn seeds inside the seed storage box from falling. As the rotating plate continues to rotate, the seeding rod, the seeding block and the bottom plate move vertically upward to return to their original position. The arrangement of this component effectively avoids the problem of uneven seeding quantity, can achieve the effect of quantitative seeding, and at the same time, avoids waste of corn seeds and avoids the influence of insufficient seed quantity and spacing.

[0020] Sweet sticky corn has high temperature requirements, especially in the low temperature season in spring. It often germinates poorly or grows slowly due to the low temperature and lagging soil temperature. By covering the soil with film, the greenhouse effect is used to increase the soil temperature, promote early seed germination and root development. Covering the film can not only effectively increase the soil temperature, but also maintain soil moisture, reduce water evaporation, and reduce weed growth, thereby effectively improving the growth rate and yield of corn. After the sweet sticky corn is planted with film, the roller 36 is rotated so that a set of loosening rakes 35 are perpendicular to the film, and the receiving plate 39 is rotated to drive the piston 310, the block 37 and the limit block through the receiving plate 39. The second 311 rotates, so that the limit block 2 311 is slidably connected to the connecting plate 31. At this time, the spring 1 38 is in a compressed state. The elastic force of the spring 1 38 causes the block 37 and the limit block 2 311 to slide into the inside of the roller 36, thereby preventing the roller 36 from moving. The device is reversed by the wheel 11. At this time, the driving motor 111 rotates in the opposite direction, so that the two sets of backfilling paddles 110 are reversed. As the device reverses, the two sets of backfilling paddles 110 flatten the film, and the electric telescopic rod 34 drives the loosening harrow 35 and the roller 36 to move vertically back and forth, so that the loosening harrow 35 punches holes in the film.

The lower surface of the fixed block 32 is fixedly connected with two sets of electric telescopic rods 34. The output ends of the two sets of electric telescopic rods 34 are fixedly connected to the connecting plate 31. The servo motor 21 drives the rotating plate 28 to rotate, so that the fixed rod 27 rotates along with the rotating plate 28. As the rotating plate 28 rotates, the driven block 26 and the cover 25 move vertically downward, so that the receiving beam 23 moves vertically downward along the inner wall of the limit block 24, thereby driving the connecting rod 29, the seeding rod 210, and the seeding block 21. 1 and the bottom plate 212 move vertically downward, so that the quantitative corn seeds at the seed block 211 move to the seed outlet 22. When the seed block 211 is separated from the inside of the base 1, the corn seeds fall into the previous groove by their own gravity. At this time, the seed rod 210 is inserted into the inside of the seed outlet 22, thereby preventing a large number of corn seeds inside the seed storage box 13 from falling. As the rotating plate 28 continues to rotate, the seed rod 210, the seed block 211 and the bottom plate 212 move vertically upward to return to their original positions, thereby achieving the effect of quantitative seeding at a certain interval.

As the device continues to move, the loosened soil is located at the trenching block (17), and the trenching block (17) separates the soil to both sides, and forms a joint in the middle, thereby achieving automatic trenching; Step 3: As the device continues to move, the soil after the trenching is moved to the seed outlet (22), and the servo motor (21) drives the rotating plate (28) to rotate, so that the fixed rod (27) rotates along with the rotating plate (28). As the rotating plate (28) rotates, the driven block (26) and the cover (25) move vertically downward, so that the receiving beam (23) moves vertically downward along the inner wall of the limit block (24), thereby driving the connecting rod (29), the seed outlet rod (210), the seed outlet block (211) and the bottom plate (212) moves vertically downward, so that the quantitative corn seeds at the seeding block (211) move to the seeding outlet (22). When the seeding block (211) is separated from the inside of the base (1), the corn seeds fall into the previous furrow by their own gravity. At this time, the seeding rod (210) is inserted into the inside of the seeding outlet (22), thereby preventing a large amount of corn seeds in the seed storage box (13) from falling. As the rotating plate (28) continues to rotate, the seeding rod (210), the seeding block (211) and the bottom plate (212) move vertically upward to return to their original positions. Step 4: After the seeds have successfully fallen into the trench, the two sets of backfill paddles (110) are driven by the driving motor (111) to rotate in opposite directions, so that the soil on both sides of the trench is backfilled following the rotation of the backfill paddles (110), thereby burying the corn seeds. When the buried soil passes through the leveling plate (112), the soil is leveled by the leveling plate (112). As the device continues to move, the film at the clamping plate (41) gradually adheres to the restored leveled soil. Step 5: After completing all the steps, the device moves to the end of the ground, rotates the roller (36), so that a group of loosening rakes (35) are perpendicular to the film, and rotates the receiving plate (39). The receiving plate (39) drives the piston (310), the block (37) and the second limit block (311) to rotate, so that the second limit block (311) and the connecting plate (31) are slidably connected. At this time, the spring (38) is in a compressed state, and the elastic force of the spring (38) causes the block (37) and the second limit block (311) to slide to the roller. (36) is positioned inside the roller (36) to prevent the roller (36) from moving. The device is reversed by the wheel (11). At this time, the driving motor (111) rotates in the opposite direction, causing the two sets of backfilling paddles (110) to reverse. As the device reverses, the two sets of backfilling paddles (110) flatten the film, and the electric telescopic rod (34) drives the loosening rake (35) and the roller (36) to move vertically back and forth, thereby punching holes in the film through the loosening rake (35), thereby achieving the purpose of planting sweet corn.
