Description

Technical Field

[0001] This invention relates to the field of seedling transplanting technology, specifically to a seedling transplanting device and method for agricultural planting. Background Technology

[0002] Agricultural planting refers to the process of using land resources to produce plants, including a series of activities such as planting crops, managing plant growth, harvesting and processing crops. Seedlings are young plant bodies in the early stages of growth after seed germination, which affect the yield of agricultural crops. Transplanting seedlings requires the use of transplanting devices, which are devices used to transplant seedlings from nursery beds or other cultivation environments to planting sites. These devices can improve transplanting efficiency, reduce damage to seedlings, and ensure that seedlings can adapt quickly to the new environment.

[0003] The existing staff first need to manually dig suitable planting holes in the ground using tools, then carefully place the seedlings into the holes, ensuring that their roots are spread out. Finally, they need to backfill and compact the soil around the seedlings to ensure the stability of the plants. Since agricultural planting usually covers a large area and requires a large number of seedlings to be transplanted, this complete process, including digging holes, placing seedlings, and backfilling, needs to be repeated by the staff hundreds or thousands of times. The most physically demanding part of the entire operation is that almost every step requires the staff to maintain a bent-over or squatting posture for a long time. This unnatural posture puts continuous pressure on the muscles of the waist and back. As the working time increases, this frequent and deep bending movement can easily lead to overwork, causing not only muscle soreness but also potentially accumulating into more serious strain. This physical fatigue directly affects the concentration and accuracy of the work, thus inevitably reducing the efficiency of the entire transplanting work.

[0004] In view of this, we propose a seedling transplanting device and transplanting method for agricultural planting. Summary of the Invention

[0005] The purpose of this invention is to provide a seedling transplanting device and method for agricultural planting, in order to solve the problem mentioned in the background art. Due to the large area of ​​agricultural planting and the large number of seedlings to be transplanted, the complete process, including digging holes, placing, and pressing, requires workers to repeat it hundreds or thousands of times. The most physically demanding part of the entire operation is that almost every step requires workers to maintain a bent or squatting posture for a long time. This unnatural posture will put continuous pressure on the waist and back muscles. As the working time increases, this frequent and deep bending movement can easily lead to overwork of the workers, which will not only cause muscle soreness, but may also accumulate into more serious strain. This physical fatigue will directly affect the concentration and accuracy of the work, thus inevitably reducing the efficiency of the entire transplanting work. To achieve the above objectives, the present invention provides the following technical solution: a seedling transplanting device for agricultural planting, comprising a support frame, wherein support legs are fixedly connected to the four corners of the bottom of the support frame, a movable frame is slidably connected inside the support frame, three circular grooves are provided on the front and rear sides of the top surface of the movable frame, and planting mechanisms for transplanting seedlings are slidably connected inside the six circular grooves, and a long frame is fixedly connected to the top of the movable frame, wherein two rectangular grooves are provided on the top of the long frame, and a moving mechanism is slidably arranged inside the rectangular grooves.

[0006] Preferably, the planting mechanism includes six inserts, each fixedly inserted into one of the six circular slots. A partition is movably inserted into the interior of each insert, with one side of the partition extending to the outside of the insert and fixedly connected to a limiting block. Three limiting plates are movably inserted into the top of the elongated frame. This arrangement of six inserts allows for the preparation of transplanting multiple seedlings in a single operation, significantly improving work efficiency. The linkage design of the partitions and limiting blocks provides a foundation for the subsequent precise release of seedlings into the planting holes.

[0007] Preferably, guide grooves are provided on both the front and rear sides of the lower side of the limiting plate, and the side of the limiting block slides in the guide groove. Arc-shaped grooves are provided on the upper sides of both the front and rear sides of the limiting plate. The guide grooves ensure that the limiting block and the partition move smoothly along the preset vertical path, preventing skewing or jamming. The arc-shaped grooves provide a smooth force application trajectory for the extrusion rod, making the partition removal action more reliable.

[0008] Preferably, the moving mechanism includes four L-shaped bars, which are slidably connected in pairs to the front and rear sides of the inner walls of the two rectangular grooves. T-shaped grooves are provided on both the left and right sides of the moving frame. The front and rear sides of the inner walls of the T-shaped grooves slide against the sides of the L-shaped bars. A compression spring is fixedly connected to each pair of opposite sides of the L-shaped bars. A triangular block is fixedly connected to one side of the horizontal bar of each L-shaped bar. A pressing rod is fixedly connected to the top of each pair of L-shaped bars. The side of the pressing rod slides against the interior of the arc-shaped groove. Under the action of the compression spring, the triangular block engages with the rack, reliably locking the height of the planting mechanism. When two pressing rods are pressed simultaneously, the sinking of the insert and the retraction of the partition can be centrally controlled.

[0009] Preferably, a convex groove is provided on one side of the support leg, and a movable block is slidably connected inside the horizontal groove of the convex groove. The side of the movable block is fixedly connected to the side of the movable frame. One side of the L-shaped strip passes through the side of the movable block. A rack is fixedly connected inside the vertical groove of the convex groove. The side of the rack slides in cooperation with the side of the triangular block. The convex groove provides a solid guide for the movable block and the entire movable frame, ensuring that the insert can move vertically downward and the drilling is straight. The cooperation between the rack and the triangular block forms a locking mechanism, which facilitates moving and fixing the insert at different heights, and makes it convenient to drill planting holes of different depths in the soil.

[0010] Preferably, an E-shaped rod is movably inserted into the left side of the top surface of the support frame. The bottom of each of the three vertical rods of the E-shaped rod is rotatably connected to a pressure roller. Grooves are provided on both the front and rear sides of the middle vertical rod of the E-shaped rod. The interior of the grooves slides in cooperation with the side of the extrusion rod. The E-shaped rod and the pressure rollers form a compaction structure. The descent of the pressure rollers is linked to the release action of the extrusion rods. No additional operation is required. The three pressure rollers can simultaneously compact the soil around the roots of multiple rows of seedlings, which is efficient and provides uniform force, thus promoting seedling survival.

[0011] Preferably, a connecting frame is fixedly connected to the bottom of the support leg, and a connecting rod is rotatably connected inside the connecting frame. A movable wheel is rotatably connected to the lower side of the connecting rod. The movable wheel facilitates the movement of the entire device in the field, greatly reducing the operator's carrying burden. The structure of the connecting frame and connecting rod ensures the flexibility of movement, allowing the device to be easily positioned at the next set of transplanting points, further improving the efficiency of continuous operation.

[0012] A method for transplanting seedlings using an agricultural seedling transplanting device includes the following steps:

[0013] S1. When transplanting seedlings, first place the seedlings to be transplanted inside the insert. At this time, the bottom of the seedling is in contact with the top of the partition. Then, the support frame and support legs move the seedlings inside the insert to the area to be planted. By pressing the two extrusion rods together towards the middle, the two L-shaped strips in a group are moved to close towards the middle of the T-shaped groove, which compresses the spring and causes the triangular blocks on the side of the L-shaped strips to release from the fixed state with the rack. This allows the moving frame to move the insert downward into the soil through the moving blocks, making holes in the soil to be planted. This saves the steps required for transplanting seedlings, reduces the fatigue of the grower, and ensures the concentration and accuracy of the workers.

[0014] S2. As the insert is inserted into the soil, the two centrally moving extrusion rods press against the limiting plate, causing the extrusion rods to move along the inside of the arc groove. This causes the limiting plate to move the guide groove on its side upward, and the limiting block to move along the inside of the guide groove. This causes the limiting block to move the partition on its side out of the insert, and then the seedling at the top of the partition moves downward by gravity into the soil hole inside the insert, allowing for quick transplanting of the seedling.

[0015] S3. During the transplanting of seedlings into the soil holes, the sides of the two inwardly closing squeezing rods contact the groove side of the middle vertical rod of the E-shaped rod, causing the E-shaped rod to move upward. During transplanting, the E-shaped rod drives the pressure roller at its bottom to move upward until it is suspended in the air. After the seedling is transplanted, the two squeezing rods are released, thereby relieving the squeezing of the groove. At this time, the E-shaped rod moves downward by gravity, and the side of the pressure roller contacts the surface of the soil. Then, the moving wheel drives the transplanting device to move out of the soil planting area. At the same time, the moving pressure roller quickly compacts the soil on both sides of the planting hole where the seedling is planted, thereby reducing the possibility of the seedling tilting after planting.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In this invention, during transplanting, the seedling is placed inside the insertion tube, with its bottom resting on the partition. After the moving device reaches the planting point, it simultaneously presses two compression rods inward, driving the L-shaped strip to compress the spring and causing the triangular block to disengage from the rack. This allows the moving frame to press the insertion tube down through the moving block, completing the drilling in the soil. This design simplifies the operation and reduces labor intensity.

[0018] In this invention, during the downward pressing of the insert, the inwardly moving extrusion rod slides along the arc-shaped groove of the limiting plate, pushing the limiting plate upward. This, in turn, drives the limiting block and partition plate out of the insert through the guide groove. The seedlings on the partition plate then fall into the pre-drilled holes by their own weight, achieving rapid planting.

[0019] In this invention, as the squeezing rod moves inward, its side contacts the groove on the E-shaped rod, pushing the E-shaped rod and the pressure roller upward and suspending them in the air. After planting, the squeezing rod is released, and the E-shaped rod falls under gravity, causing the pressure roller to contact the ground. When the device is moved out by the moving wheels, the pressure roller immediately compacts the soil around the planting hole, improving the upright stability of the seedling.

[0043] Example 3:

[0044] Please see Figures 1 to 10 This embodiment provides a technical solution:

[0045] An E-shaped rod 101 is movably inserted into the left side of the top surface of the support frame 1. The bottom of the three vertical rods of the E-shaped rod 101 is rotatably connected to the pressure roller 102.

[0047] In this embodiment, the E-shaped rod 101 and the pressure roller 102 constitute a compaction structure. The descent of the pressure roller 102 is linked to the release action of the extrusion rod 805, requiring no additional operation. The three pressure rollers 102 can simultaneously compact the soil around the roots of multiple rows of seedlings, resulting in high efficiency and uniform force distribution, which is beneficial to seedling survival. The moving wheels 206 facilitate the movement of the entire device in the field, greatly reducing the operator's carrying burden. The structure of the connecting frame 204 and the connecting rod 205 ensures the flexibility of movement, allowing the device to be easily positioned at the next group of transplanting points, further improving the efficiency of continuous operation.

[0048] A method for transplanting seedlings using an agricultural seedling transplanting device includes the following steps:

[0049] S1. When it is necessary to transplant seedlings, first place the seedlings to be transplanted inside the insert 501. At this time, the bottom of the seedling is in contact with the top of the partition 502. Then, the seedling inside the insert 501 is moved to the planting area by the support frame 1 and the support leg 2. By pressing the two extrusion rods 805 together towards the middle, the two L-shaped strips 801 as a group are moved to close towards the middle of the inner wall of the T-shaped groove 802, so that the compression spring 803 is compressed and the L-shaped strips 801 move the triangular block 804 on its side to release the fixed state with the rack 203. Then, the moving frame 3 moves the insert 501 downward into the soil through the moving block 202 to make holes in the soil to be planted. This saves the steps required for transplanting seedlings, reduces the fatigue of the grower, and ensures the concentration and accuracy of the workers.

[0050] S2. During the process of inserting the tube 501 into the soil, the two centrally moving extrusion rods 805 extrude pressure on the limiting plate 504, causing the extrusion rods 805 to move along the inside of the arc groove 506, and causing the limiting plate 504 to move the guide groove 505 on its side upward, and causing the limiting block 503 to move along the inside of the guide groove 505, causing the limiting block 503 to move the partition plate 502 on its side out of the tube 501, and then causing the seedling at the top of the partition plate 502 to move downward by gravity into the soil hole made inside the tube 501, so that the seedling can be quickly transplanted.

[0051] S3. During the transplanting of seedlings into the soil holes, the sides of the two inwardly closing squeezing rods 805 contact the side of the groove 103 of the middle vertical rod of the E-shaped rod 101, causing the E-shaped rod 101 to move upward. During transplanting, the E-shaped rod 101 drives the pressure roller 102 at its bottom to move upward until it is suspended in the air. After the seedling is transplanted, the two squeezing rods 805 are released, thereby relieving the squeezing state on the groove 103. At this time, the E-shaped rod 101 moves downward by gravity, and the side of the pressure roller 102 contacts the surface of the soil. At this time, the moving wheel 206 drives the transplanting device to move out of the soil planting area. At the same time, the moving pressure roller 102 quickly compacts the soil on both sides of the soil planting hole where the seedling is planted, thereby reducing the possibility of the seedling tilting after planting.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
