Abstract
Description
Technical Field
[0001] This utility model relates to the field of portable seeding device technology, specifically a portable seeding device for crops. Background Technology
[0002] Currently, most crops require many holes to be drilled in the field before sowing, such as broad beans. Broad bean production has developed from the stage of auxiliary food crop production before the 1980s to the stage of commodity economic crop production and development, and the planting area of broad beans has extended to dryland areas.
[0003] Generally, broad bean sowing requires laying mulch film before planting the broad beans. This involves making a hole in the mulch film, extending deep into the soil, and then placing the broad bean seeds into the hole. Although some mechanized hole-drilling and sowing equipment has emerged that can solve the sowing problem, the equipment is too large and expensive to be suitable for all fields or farmers, especially in rugged mountainous and plateau areas.
[0004] Chinese patent CN216253876U discloses a portable crop sowing tool.
[0005] This invention relates to the field of seeding tools. A portable crop seeding tool includes a seed delivery tube and a baffle plate for blocking the bottom opening of the seed delivery tube, the baffle plate being rotatably connected to the seed delivery tube. Using this invention, seeds are easily sown into the soil, the spacing between plants and the number of seeds can be controlled, and the sowing depth can be kept consistent. It is easy to operate, saves time and labor, and improves crop planting efficiency and uniformity.
[0006] However, the above patent has the following shortcomings: The above patent uses a worker to turn a knob to drive a rotating shaft, which in turn drives a gear to rotate, thereby causing the seeds to fall into the bottom opening of the conveying pipe in sequence, which facilitates seed sowing. However, in actual use, the worker needs to stop and turn the knob repeatedly, which is not only time-consuming but also inefficient and not conducive to the worker to sowing quickly. Therefore, it needs to be improved. Utility Model Content

As the seed-breaking head is inserted into the soil, it is equivalent to pushing the U-shaped plate upward. The U-shaped plate drives the first guide rod and the toothed plate to move upward under the guidance of the second guide body. Since the toothed plate and the gear are meshed, the gear is driven to rotate 180 degrees. The gear then drives the rotating roller to rotate 180 degrees, thereby turning the seeds in the seeding trough to the bottom of the seed-breaking head for sowing.

Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please refer to Figures 1-5. This utility model provides a technical solution: a portable crop sowing device, including a mounting plate 1, on which multiple soil-breaking sowing heads 2 are vertically mounted, and the soil-breaking sowing heads 2 are internally equipped with...
[0036] It is equipped with a seed feeding component, a drive component is provided on the outside of the soil breaking and sowing head 2, and a user-friendly component is provided on the top of the mounting plate 1;
[0037] The drive assembly includes a first guide rod 4, a toothed plate 5, a gear 8, a second guide body 9, and a U-shaped plate 10. The second guide body 9 is installed on the outside of the soil-breaking seeding head 2. The first guide rod 4 slides vertically through the second guide body 9. The U-shaped plate 10 is installed at the bottom of the first guide rod 4. The toothed plate 5 is installed vertically at the top of the first guide rod 4. The gear 8 is meshed on the outside of the toothed plate 5.
[0038] Specifically, during the process of inserting the seed-breaking head 2 into the soil, the U-shaped plate 10 comes into contact with the soil. As the seed-breaking head 2 is inserted, it effectively pushes the U-shaped plate 10 upwards. The U-shaped plate 10 then drives the first guide rod 4 and the toothed plate 5 to move upwards under the guidance of the second guide body 9. Since the toothed plate 5 and the gear 8 are meshed, the gear 8 rotates 180 degrees, which in turn drives the rotating roller 11 to rotate 180 degrees. This process flips the seeds in the seeding trough 12 to the bottom of the seed-breaking head 2 for sowing. The vertical movement of the toothed plate 5 is precisely enough to drive the rotating roller 11 to rotate 180 degrees back and forth, which not only improves production efficiency but also reduces the frequency of operation steps.
[0039] Furthermore, a first guide body 3 is installed on the outside of the soil-breaking seed head 2, and a second guide rod 6 slides vertically through the first guide body 3. The bottom of the second guide rod 6 is installed on the top of the toothed plate 5, and a return spring 7 is sleeved on the outside of the second guide rod 6.
[0040] Specifically, after the toothed plate 5 moves to the top position, the seeding head 2 is pulled out of the soil. At this time, the second guide rod 6 pushes the toothed plate 5 downward under the action of the return spring 7. The downward toothed plate 5 can drive the first guide rod 4 and the U-shaped plate 10 to return to their original positions. The downward toothed plate 5 drives the gear 8 and the rotating roller 11 to rotate back to their original positions, providing conditions for the next sowing.
[0041] Furthermore, the seed feeding assembly includes a rotating roller 11 and a seeding trough 12. The rotating roller 11 is rotatably installed inside the soil-breaking seeding head 2, and the top of the rotating roller 11 is provided with a seeding trough 12. A gear 8 is installed through the end of the rotating roller 11 and through the soil-breaking seeding head 2.
[0042] Specifically, after the gear 8 drives the rotating roller 11 to rotate 180 degrees, the seeds in the seeding trough 12 at the top of the rotating roller 11 are flipped to the bottom position of the soil-breaking seeding head 2 for sowing. When the toothed plate 5 rebounds, the gear 8 rotates in the opposite direction, driving the rotating roller 11 to rotate. The rotating roller 11 flips the seeding trough 12 to the top position, providing conditions for the next sowing.
[0043] Furthermore, the U-shaped plate 10 is fitted onto the outside of the soil-breaking and seeding head 2, and the U-shaped plate 10 is slidably connected to the soil-breaking and seeding head 2;
[0044] Specifically, during the up-and-down movement of the U-shaped plate 10 outside the soil-breaking and seeding head 2, the residual soil on the soil-breaking and seeding head 2 can be cleaned by the downward movement of the U-shaped plate 10.
[0045] Furthermore, the top of the mounting plate 1 is installed to the bottom of the seed bin 13, and the mounting plate 1 is connected to the bottom of the seed bin 13;
[0046] Specifically, by installing the seed bin 13, seeds can be directly poured into the seed bin 13 for continuous sowing.
[0047] Furthermore, a movable cover 14 is rotatably mounted on the top of the seed bin 13, and the movable cover 14 is used to close the top of the seed bin 13;
[0048] Specifically, the movable cover 14 installed on the top of the seed bin 13 can block the seeds inside the seed bin 13 and prevent the seeds inside the seed bin 13 from spilling.
[0049] Furthermore, the easy-to-use components include extension rods 15, handles 16, and rubber sleeves 17. Extension rods 15 are symmetrically and vertically mounted on the top of the mounting plate 1, and handles 16 are installed between the extension rods 15. Rubber sleeves 17 are symmetrically fitted on the outside of the handles 16.
[0050] Specifically, the worker holds the rubber sleeve 17 with both hands, then lifts the seed upwards and inserts it into the soil for easy sowing.
[0051] Furthermore, magnets 18 are symmetrically installed on the movable cover 14 near the extension rod 15. Specifically, when the movable cover 14 on the top of the seed chamber 13 is opened, the magnets 18 installed on the movable cover 14 are attracted to the extension rod 15, thereby restricting the movable cover 14 and preventing it from falling freely without restraint, thus preventing workers from adding seeds into the seed chamber 13.
[0052] Working principle: When using this portable crop seeding device, as the soil-breaking seeding head 2 is inserted into the soil, the U-shaped plate 10 comes into contact with the soil. The insertion of the seeding head 2 into the soil effectively pushes the U-shaped plate 10 upwards. The U-shaped plate 10 then drives the first guide rod 4 and the toothed plate 5 to move upwards under the guidance of the second guide body 9. Since the toothed plate 5 and the gear 8 are meshed, the gear 8 rotates 180 degrees, which in turn drives the rotating roller 11 to rotate 180 degrees, thus achieving the sowing of the seeds in the seeding trough 12. The seeds are flipped to the bottom of the sowing head 2 for sowing. After the toothed plate 5 moves to the top position, the sowing head 2 is pulled out of the soil. At this time, the second guide rod 6 pushes the toothed plate 5 down under the action of the return spring 7. The down-moving toothed plate 5 can drive the first guide rod 4 and the U-shaped plate 10 to return to their original positions. The down-moving toothed plate 5 drives the gear 8 and the rotating roller 11 to rotate back to their original positions, providing conditions for the next sowing.
