Abstract
Description
Technical Field
[0001] This utility model relates to the field of transplanter technology, and in particular to a rapeseed transplanter. Background Technology
[0002] Rapeseed is an annual or perennial herbaceous plant belonging to the Brassicaceae family and the Brassica genus. It is an important oil crop. Its seedlings and leaves are edible, and its seeds can be pressed for oil. Transplanting rapeseed makes full use of land resources. Seedlings are raised in seedbeds before the previous crop is harvested, saving land by concentrating seedlings in the seedbed. This facilitates centralized seedling management, allowing for precise watering, fertilization, weeding, and pest and disease control, and controlling the seedbed environment. Healthy and uniform seedlings are selected for transplanting, improving the uniformity of plant growth in the field. During transplanting, the rapeseed is first removed from the seedbed... When terrain limitations prevent the use of large machinery, handheld transplanters are needed for transplanting rapeseed. The handheld transplanter mainly consists of a round tube, a handle, and a soil inserter. During the transplanting process, the soil inserter is inserted into the soil, and the rapeseed seedling is placed inside the round tube. The rapeseed seedling will fall onto the inner wall of the soil inserter. At this time, hold the handle, and the handle will drive the connecting ring upward through the first connecting rod. The connecting ring will drive the soil inserter to rotate open through the second connecting rod, so that the rapeseed seedling falls into the transplanting pit made by the soil inserter.
[0003] During the transplanting process, because rapeseed seedlings are relatively soft and the internal space of the planting head is large, the rapeseed seedlings are tilted inside the planting head. After the rapeseed seedlings are inserted into the soil, they are also tilted, which will affect the subsequent growth of the rapeseed seedlings. Therefore, this application provides a rapeseed transplanting machine to meet the needs. Summary of the Invention
[0004] This utility model provides a special rapeseed transplanter to solve the problem that the subsequent growth of rapeseed seedlings is affected after transplanting them at an angle.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A rapeseed transplanter includes a transplanter body and a soil-inserting head installed at the bottom of the transplanter body, and further includes:
[0007] The straightening mechanism includes an installation ring disposed inside the transplanter body, with several straightening components fixed to the bottom of the installation ring. The several straightening components are arranged in a circular array and are attached to the inner wall of the soil insertion head.
[0008] When transplanting rapeseed, hold the handle on the transplanter body to open the soil-inserting head. As the rapeseed falls, the straightening device will straighten it.
[0009] Preferably, a limiting ring is fixed to the inner wall of the transplanter body, the side of the mounting ring is movably connected to the inner wall of the transplanter body, and the bottom of the transplanter body is attached to the top of the limiting ring.
[0010] Preferably, the top of the limiting ring has an upper inclined surface, and the bottom of the mounting ring has a lower inclined surface corresponding to the upper inclined surface, with the upper inclined surface fitting against the surface of the lower inclined surface.
[0011] Preferably, the top of the mounting ring is provided with a guide surface.
[0012] Preferably, a connecting rod is fixed to the surface of the upper inclined surface, and the top of the connecting rod extends out of the top of the transplanter body.
[0013] Preferably, a top ball is fixed to the end of the connecting rod that extends out of the transplanter body.
[0014] Preferably, the straightening component includes a vertical part fixed to the bottom of the mounting ring, and the bottom of the vertical part has an integrally formed bent part that fits against the inner wall of the soil insertion head.
[0015] Preferably, the end of the bending portion is integrally formed with a bending portion, which fits against the inner wall of the insertion head.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, by setting up an installation ring and a straightening component, during the transplanting process, the rapeseed seedling is positioned between the planting head and the soil head. The bending part of the straightening component helps to straighten the rapeseed seedling. When the soil head is opened, the bending part expands outward as the soil head opens, making it easier for the rapeseed seedling to fall downward. During the downward fall of the rapeseed seedling, the bending part prevents the rapeseed seedling from tilting, allowing the rapeseed seedling to be inserted into the soil relatively straight, ensuring the subsequent growth of the rapeseed seedling.
[0018] By setting a limit ring and a connecting rod, the limit ring is used to limit the installation ring, preventing the installation ring from moving downwards excessively and improving the stability after installation. When it is necessary to disassemble the uprighting component, the connecting rod makes it easier to remove the installation ring from the inside of the transplanter body, making the operation more convenient.
[0019] By setting up upper and lower slopes, when the mounting ring is not installed, the lower slope can prevent other materials from accumulating on the top of the limiting ring, thus affecting its use. During the installation of the mounting ring, the lower slope can guide the mounting ring, allowing it to quickly snap into place on the top of the limiting ring. Furthermore, the snapping action of the upper and lower slopes makes the mounting ring more stable after it is fixed, preventing it from shaking during use.
[0020] By setting a guide surface, the rapeseed seedlings can be guided after the installation ring is installed and during the transplanting process, preventing the seedlings from getting stuck on the top of the installation ring. This eliminates the need to shake the transplanter body, making operation more convenient. Attached Figure Description

[0027] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model.

Detailed Implementation
[0028] The following is a detailed description of a rapeseed transplanter provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0029] like Figures 1-5As shown, an embodiment of this utility model provides a rapeseed transplanter, including a transplanter body 1 and a soil-inserting head 2 installed at the bottom of the transplanter body 1. The transplanter body 1 is provided with a handle, a first connecting rod, a second connecting rod, and a connecting ring. During transplanting, holding the handle and rotating the handle will cause the first connecting rod to move upward, the first connecting rod to move the connecting ring upward, the connecting ring to move the second connecting rod upward, and the second connecting rod to rotate and open the soil-inserting head 2. The device also includes:
[0030] The straightening mechanism 3 includes an installation ring 5 set inside the transplanter body 1. Several straightening components 11 are fixed at the bottom of the installation ring 5. The several straightening components 11 are arranged in a circular array and are attached to the inner wall of the soil insertion head 2.
[0031] When transplanting rapeseed, hold the handle on the transplanter body 1 to open the soil insertion head 2. As the rapeseed falls, the straightening component 11 straightens it. During the rapeseed transplanting process, the mounting ring 5 in the straightening mechanism 3 works in conjunction with the straightening component 11. The straightening component 11, distributed in a ring array, fits tightly against the inner wall of the soil insertion head 2. Its bent part 13 and folded part 14 can accurately correct the rapeseed posture, ensuring that the rapeseed always remains vertical when falling. When the soil insertion head 2 is opened, the straightening component 11 expands outward, providing a channel for the rapeseed seedling to fall and continuously limiting its position to prevent tilting. This ensures that the rapeseed seedling is inserted into the soil in the best posture, significantly improving the transplant survival rate and the uniformity of the plant's later growth.
[0032] like Figure 2 As shown in this embodiment, a limiting ring 4 is fixed to the inner wall of the transplanter body 1, and the side of the mounting ring 5 is movably connected to the inner wall of the transplanter body 1. The bottom of the transplanter body 1 is attached to the top of the limiting ring 4. The limiting ring 4 provides stable limiting support for the mounting ring 5, preventing the mounting ring 5 from moving excessively downward or shaking inside the transplanter body 1, ensuring that the position of the straightening mechanism 3 is fixed during the transplanting process, so that the straightening component 11 always maintains precise cooperation with the soil insertion head 2. At the same time, the attachment of the bottom of the transplanter body 1 to the limiting ring 4 further enhances the structural stability of the whole machine and ensures that the transplanting operation is continuous and reliable.
[0033] like Figure 2 , Figure 4 and Figure 5As shown in this embodiment, the top of the limiting ring 4 is provided with an upper inclined surface 8, and the bottom of the mounting ring 5 is provided with a lower inclined surface 9 corresponding to the upper inclined surface 8. The upper inclined surface 8 fits against the surface of the lower inclined surface 9. The design of the upper inclined surface 8 and the lower inclined surface 9 forms a precise guiding and locking structure. Before installation, the lower inclined surface 9 can prevent soil and debris from accumulating on the top of the limiting ring 4 and affecting the installation. During installation, the two inclined surfaces cooperate to quickly guide the mounting ring 5 to fall accurately into the top of the limiting ring 4, reducing the alignment time. After installation, the tight fit between the inclined surfaces forms a mechanical lock, which enhances the stability of the mounting ring 5 after it is fixed, effectively resists vibration and external impact during transplanting, and prevents the mounting ring 5 from loosening and shifting.
[0034] like Figure 2 and Figure 4 As shown in this embodiment, the top of the mounting ring 5 is provided with a guide surface 10. The guide surface 10 can smoothly guide the falling rapeseed seedlings during the transplanting process, preventing the rapeseed seedlings from getting stuck, tilting or tangling due to collision with the top edge of the mounting ring 5. This eliminates the need for operators to manually shake the transplanter body 1 to adjust the position of the rapeseed seedlings, significantly improving transplanting efficiency. At the same time, it ensures a smooth falling path for the rapeseed seedlings, creating favorable conditions for the straightening component 11 to accurately straighten them.
[0035] like Figure 2 and Figure 3 As shown in this embodiment, a connecting rod 6 is fixed to the surface of the upper inclined surface 8. The top of the connecting rod 6 extends out of the top of the transplanter body 1. The connecting rod 6 provides a convenient point of leverage for the disassembly and maintenance of the mounting ring 5. When it is necessary to replace or repair the straightening mechanism 3, the operator can easily remove the mounting ring 5 along with the straightening component 11 from the inside of the transplanter body 1 by pulling the connecting rod 6. This avoids the difficulty of disassembly caused by the mounting ring 5 being too tightly fitted, greatly simplifies the maintenance process, and reduces the intensity of manual operation.
[0036] like Figure 3 As shown in this embodiment, a top ball 7 is fixed to the end of the connecting rod 6 that extends out of the transplanter body 1. The top ball 7 increases the contact area when pulling the connecting rod 6, avoiding pain caused by concentrated force on the hand, while providing a more stable grip point to prevent the hand from slipping during the lifting process. In addition, the smooth design of the top ball 7 can prevent it from scratching or damaging other parts on the top of the transplanter body 1, protecting the appearance and performance of the equipment.
[0037] like Figure 2 and Figure 4As shown in this embodiment, the straightening component 11 includes a vertical part 12 fixed to the bottom of the mounting ring 5. The bottom of the vertical part 12 is integrally formed with a bent part 13. The bent part 13 fits against the inner wall of the planting head 2. The vertical part 12 provides a stable support foundation for the bent part 13, ensuring that it maintains a stable posture inside the planting head 2. The bent part 13 fits against the inner wall of the planting head 2, which can quickly correct the posture of the rapeseed seedling by physical limiting when the seedling falls, making it perpendicular to the central axis of the planting head 2. At the same time, when the planting head 2 is opened, the bent part 13 can elastically deform as the planting head 2 expands, which can not only ensure that the rapeseed seedling falls smoothly, but also continue to play a straightening role and improve the transplanting accuracy.
[0038] like Figure 2 and Figure 4 As shown in this embodiment, the end of the bent part 13 is integrally formed with a bent part 14. The contact area between the bent part 14 and the soil insertion head 2 is larger, making the bent part 13 more stable. The bent part 14 fits into the inner wall of the soil insertion head 2. The smooth transition design between the bent part 14 and the bent part 13 can reduce frictional damage to the rapeseed seedling stem, ensure the integrity of the plant, and improve the transplanting quality.
[0039] Working principle: The operator holds the handle on the transplanter body 1, inserts the soil inserting head 2 into the soil, and drops the rapeseed seedling into the transplanter body 1. Then, the soil inserting head 2 is opened. During the fall of the rapeseed, the bending part 13 of the straightening component 11 straightens the rapeseed to ensure its vertical position. After the soil inserting head 2 is opened, the bending part 13 expands with the soil inserting head 2, allowing the rapeseed seedling to fall smoothly. During this process, the straightening component 11 continuously prevents the rapeseed seedling from tilting, ensuring that it is inserted straight into the soil. During the transplanting process, the guide surface 10 at the top of the mounting ring 5 guides the rapeseed seedling to prevent it from getting stuck on the top of the mounting ring 5. At the same time, the limiting ring 4 cooperates with the lower inclined surface 9 of the mounting ring 5 through the upper inclined surface 8 to limit the downward movement of the mounting ring 5 and provide stable support to prevent the mounting ring 5 from shaking. If it is necessary to disassemble the straightening mechanism 3, the operator can remove the mounting ring 5 from the transplanter body 1 through the connecting rod 6 and the top ball 7 to complete the maintenance or replacement operation.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
