Description

Technical Field

[0001] The utility model relates to the technical field of seedling planting devices, in particular to a sweet potato seedling soil planting device. Background Technique

[0002] Sweet potato sprouts, also known as sweet potato leaves and sweet potato shoots, are plants of the genus Ipomoea batatas in the Convolvulaceae family. They are varieties of the tender stems at the top of sweet potato seedlings selected for human consumption through artificial selection and are truly green vegetable products.

[0003] In the later growth stage of sweet potato seedlings, they must be transplanted into the soil to ensure their normal growth. Existing planting technologies, such as the utility model with the publication number CN217389395U, although providing a solution, have significant problems in practice. The planting device described in this patent is equipped with a seed carrier with a conical bottom. Although this design simplifies the planting process, unfortunately, it leaves pits around the seedlings. The existence of these pits exposes part of the seedling roots outside the soil, which is not conducive to the water absorption and nutrient uptake of the seedlings, thereby affecting their growth rate and health status. Moreover, these pits may become risk points for the seedlings to fall over in strong winds. Once the seedlings fall over due to the pits, manual re-erection is required, increasing labor costs and time investment. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a sweet potato seedling soil planting device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A sweet potato seedling soil planting device includes a fixing plate. One end of the fixing plate is sleeved with a bidirectional threaded rod. Both ends of the bidirectional threaded rod are sleeved with second ball heads. Each second ball head is embedded in one end of a control handle. One end of each control handle away from the second ball head is sleeved with a second bearing. A soil covering wheel is provided beside each second bearing. A first bearing is sleeved inside each soil covering wheel. The first bearing and the second bearing are both sleeved on a ball head seat. A first ball head is fitted inside each ball head seat. A fixing handle is fixed on each first ball head. A sector block is fixed on the side of one end of each fixing handle away from the first ball head. A fixing seat is sleeved on the end of the fixing handle beside each sector block. An installation plate is fixed on each fixing seat. A second limiting block is fixed on each installation plate. A plurality of second limiting blocks are clamped at both ends of a connecting rod. A pulling block is fixed at one end of the connecting rod. The control handle cooperates with the ball head seat and the bidirectional threaded rod to control the tilting angle of the soil covering wheel, so as to adapt to the soil covering amount of seedlings of different sizes.

[0006] Preferably, a plurality of sliding grooves are formed inside one end of the control handle where the second ball head is located, and a sliding rail is arranged in each sliding groove. Each sliding rail is fixed on the surface of the second ball head. The sliding rail cooperates with the sliding groove to prevent the second ball head from rotating along with the bidirectional threaded rod and ensure that the second ball head can rotate left and right at the end of the control handle.

[0007] Preferably, a plurality of notches are evenly formed on the sector block, and the notches cooperate with the connecting rod to limit the rotation of the sector block.

[0008] Preferably, a slot is formed at the position of the mounting plate where the sector block is located, facilitating the sector block to pass through the mounting plate.

[0009] Preferably, a plurality of first limit blocks are fixed on one side of the mounting plate on both sides of the pulling block, and the first limit blocks are used to prevent the pulling block from driving the connecting rod to rotate.

[0010] Preferably, the mounting plate is fixed on the planting device. A plurality of rotating shafts are arranged at the bottom of the planting device, and moving wheels are fixed at both ends of each rotating shaft. The planting device is used for planting seedlings, and the rotating shafts cooperate with the moving wheels to move the planting device.

[0011] Preferably, one end of the fixing plate away from the bidirectional threaded rod is sleeved on the rotating shaft. The fixing rod is used to limit the displacement of the bidirectional threaded rod, preventing the end of the control handle sleeved with the bidirectional threaded rod from falling to the ground due to gravity, thereby affecting the operation of the device.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model realizes the later-stage soil covering work for seedlings through the soil covering wheel, control handle, bidirectional threaded rod, first ball head, second ball head, fixed handle, sector block and connecting rod, effectively avoiding the problem of seedling toppling caused by failure to cover soil in time in the later stage. It not only stabilizes the growth environment of the plants but also significantly improves the survival rate of the seedlings, ensuring the healthy development of sweet potato seedlings and the basis for a good harvest.

[0025] Please refer to Figure 1-7, the present utility model provides a technical solution: a sweet potato seedling soil-planting and fixing device, including a fixing plate 3. One end of the fixing plate 3 is sleeved with a bidirectional threaded rod 16. Both ends of the bidirectional threaded rod 16 are sleeved with second ball heads 23. Each second ball head 23 is embedded in one end of a control handle 9. One end of each control handle 9 away from the second ball head 23 is sleeved with a second bearing 21. A soil covering wheel 8 is arranged beside each second bearing 21. A first bearing 20 is sleeved in each soil covering wheel 8. Both the first bearing 20 and the second bearing 21 are sleeved on a ball head seat 13. A first ball head 19 is fitted in each ball head seat 13. A fixing handle 6 is fixed on each first ball head 19. A sector block 7 is fixed on the side of one end of each fixing handle 6 away from the first ball head 19. A fixing seat 18 is sleeved on the end of the fixing handle 6 beside each sector block 7. An installation plate 5 is fixed on each fixing seat 18. A second limiting block 15 is fixed on each installation plate 5. A number of second limiting blocks 15 are clamped at both ends of a connecting rod 14. A pulling block 10 is fixed at one end of the connecting rod 14. The control handle 9 cooperates with the ball head seat 13 and the bidirectional threaded rod 16 to control the inclination angle of the soil covering wheel 8, so as to adapt to the soil covering amount of seedlings of different sizes.

[0026] Further, a number of sliding grooves 22 are opened inside one end of the control handle 9 where the second ball head 23 is located. A sliding rail 24 is arranged in each sliding groove 22. Each sliding rail 24 is fixed on the surface of the second ball head 23. The sliding rail 24 cooperates with the sliding groove 22 to prevent the second ball head 23 from rotating along with the bidirectional threaded rod 16, and ensure that the second ball head 23 can rotate left and right at the end of the control handle 9.

[0027] Further, a number of notches 17 are evenly opened on the sector block 7. The notches 17 cooperate with the connecting rod 14 to limit the rotation of the sector block 7.

[0028] Further, a slot 12 is opened at the position of the installation plate 5 where the sector block 7 is located, which is convenient for the sector block 7 to pass through the installation plate 5.

[0029] Further, a number of first limiting blocks 11 are fixed on one side of the installation plate 5 on both sides of the pulling block 10. The first limiting blocks 11 are used to prevent the pulling block 10 from driving the connecting rod 14 to rotate.

[0030] Further, the installation plate 5 is fixed on a planting device 1. A number of rotating shafts 2 are arranged at the bottom of the planting device 1. Moving wheels 4 are fixed at both ends of each rotating shaft 2. The planting device 1 is used for planting seedlings. The rotating shafts 2 cooperate with the moving wheels 4 to move the planting device 1.

[0031] Further, the end of the fixing plate 3 away from the bidirectional threaded rod 16 is sleeved on the rotating shaft 2. The fixing rod is used to limit the displacement of the bidirectional threaded rod 16, and prevent the end of the control handle 9 sleeved with the bidirectional threaded rod 16 from falling to the ground due to gravity, thus affecting the operation of the device.

[0032] Working principle: Before using the device, first determine the amount of soil covering required for planting seedlings. By pulling the pulling block 10, the connecting rod 14 is driven to move, enabling the sector block 7 to rotate. The rotation of the sector block 7 drives the fixed handle 6 to rotate. Since one end of the fixed handle 6 is sleeved on the fixed seat 18, the other end drives the soil covering wheel 8, the control handle 9, and the bidirectional threaded rod 16 to move up and down when the fixed handle 6 rotates, thereby controlling the depth of the soil covering wheel 8 embedded in the soil. After adjusting the soil covering wheel 8 to the required height, push the pulling block 10, thereby pushing the connecting rod 14, so that the connecting rod 14 is stuck at the notch 17 on the sector block 7, preventing the sector block 7 from continuing to rotate. During the downward movement of the soil covering wheel 8 and the bidirectional threaded rod 16, due to the relatively long length of the fixed plate 3, the fixed plate 3 presses against the bidirectional threaded rod 16, thereby preventing the control handle 9 from rotating and falling to the ground due to the gravity of the bidirectional threaded rod 16.

[0033] After adjusting the soil covering wheel 8 to the required height, rotate the bidirectional threaded rod 16 to make the control handles 9 at both ends approach or move away from each other, and adjust the inclination angle of the control handle 9. Since both the control handle 9 and the soil covering wheel 8 are sleeved on the same ball head seat 13, the inclination angle of the soil covering wheel 8 changes with the change of the inclination angle of the control handle 9. The first ball head 19 at the end of the fixed handle 6 cooperates with the ball head seat 13 to offset the torsion caused by the inclination of the soil covering wheel 8. The second ball heads 23 at both ends of the bidirectional threaded rod 16 are used to offset the torsion caused by the inclination of the control handle 9. A number of slide rails 24 on the surface of the second ball head 23 cooperate with a number of chutes 22 opened inside the control handle 9 to prevent the second ball head 23 from rotating with the bidirectional threaded rod 16, while ensuring that the second ball head 23 can tilt left and right. After adjusting the inclination angle and height of the soil covering wheel 8, the planting work can begin. The soil covering wheel 8 pushes the soil on both sides of the planted seedlings towards the seedlings and covers the roots of the seedlings.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
