Description

Technical Field

[0001] This invention relates to the field of agricultural transplanting machinery technology, and in particular to a seedling support and soil-holding device. Background Technology

[0002] Currently, due to the advantages of transplanting machines such as time-saving, high efficiency, and cost-effectiveness, their application is becoming increasingly widespread. However, mechanical transplanting also has some shortcomings, the most critical of which is the inability to effectively guarantee the uprightness of the seedlings. During the planting process, the planting of seedlings mainly involves the interaction between the planting device and the soil. Taking the duckbill planting device as an example, after the seedling enters the device, it is successfully planted into the soil through the punching and opening action of the device. In this process, factors such as the forward speed of the transplanter and the return stroke of the planting device can cause the seedlings to be not upright after planting, and in severe cases, they may even fall over. This will undoubtedly affect the normal growth of the seedlings and may even cause the roots of the seedlings to be exposed and die. Therefore, it is necessary to straighten the seedlings after planting and keep them stable to promote healthy growth and increase yield.

[0003] Some seedling support devices have also been disclosed in the prior art, such as publication number CN112740882B. This patent also involves the issue of seedling support, but after supporting the seedlings, it is not possible to cover and compact the soil well, and there is still a possibility that the seedlings in the pots may tilt. Summary of the Invention

This can avoid damage to the seedlings caused by the soil covering device due to the displacement of the seedlings.

[0017] 3. This invention uses a soil compactor to compact the soil around the seedling. When compacting the soil, the soil is gathered and compacted from around the seedling, ensuring the seedling's uprightness without damaging it. Attached Figure Description

[0026] Please see Figure 1-6This invention provides a seedling support and soil-supporting device, including a frame 1. A first horizontal moving mechanism 4 is provided on the frame 1. A straightening mechanism 2 and a soil-supporting mechanism 3 are provided opposite each other at the lower end of the first horizontal moving mechanism 4. The soil-supporting mechanism 3 is connected to the first horizontal moving mechanism 4 through a second horizontal moving mechanism. The first horizontal moving mechanism 4 is used to drive the straightening mechanism 2 and the second horizontal moving mechanism to move simultaneously in the horizontal direction. The second horizontal moving mechanism is used to drive the soil-supporting mechanism 3 to move in the horizontal direction. The moving direction of the first horizontal moving mechanism 4 is consistent with the moving direction of the second horizontal moving mechanism. The straightening mechanism 2 is used to straighten seedlings that do not meet the standard of uprightness. The soil-supporting mechanism 3 is used to support the soil around the roots of the seedlings to achieve soil support and seedling fixation.

[0027] Combination Figure 1 and Figure 2 As shown, the first horizontal moving mechanism 4 includes a first drive motor 48, a first lead screw 42 connected to the first drive motor 48, a first lead screw nut 43 disposed on the first lead screw 42, a crossbeam 44 connected to the first lead screw nut 43, and a support plate 45 disposed at the lower end of the crossbeam 44. The straightening mechanism 2 and the second horizontal moving mechanism are disposed at the lower end of the support plate 45. The two ends of the crossbeam 44 are slidably connected to the frame 1. Two first slide rails 41 are provided opposite to each other on the frame 1. A first slider 49 is slidably disposed on the first slide rails 41. The two ends of the crossbeam 44 are connected to the first slider 49 through vertical plates. The vertical plate is connected to the first slider 49 by bolts. The first lead screw 42 is set parallel to the first slide rail 41 and located between the two first slide rails 41. The first lead screw 42 is connected to the output shaft of the first drive motor 48 through the first coupling 46. The first drive motor 48 is mounted on the frame 1 through the first drive motor connector 47. The first drive motor 48 rotates, thereby driving the first lead screw 42 to rotate. Under the action of the first lead screw nut 43, the first slide rail 41, and the first slider 49, the crossbeam 44 and the support plate 45 on the crossbeam 44 can move horizontally back and forth.

[0028] Combination Figure 1 and Figure 3As shown, the straightening mechanism 2 includes a seedling support rod 25, an intermediate connecting plate 28 connected to the support plate 45, a lower fixing plate 27 disposed at the lower end of the intermediate connecting plate 28, a seedling support motor 23 disposed on the lower fixing plate 27, and a seedling support crank 24 disposed on the output shaft of the seedling support motor 23. The intermediate connecting plate 28 is inverted L-shaped and has a first horizontal part and a first vertical part. The first horizontal part of the intermediate connecting plate 28 is fixedly connected to the support plate 45, and the first vertical part of the intermediate connecting plate 28 is welded to the intermediate connecting plate 28. The lower fixing plate 27 is provided with a first arc-shaped sliding groove 271. The seedling support rod 25 includes a connecting plate, which is slidably disposed in the first arc-shaped groove 271. Inside the shaped groove 271, a movable rod facing the seedling support crank 24 is provided on one side of the connecting plate, and two seedling support rods 251 are provided on the other side. The two seedling support rods 251 are arranged in parallel and perpendicular to the connecting plate. The seedling support rods 251 face the soil-supporting mechanism 3. The seedling support crank 24 is provided with an oblong groove that slides with the movable rod. The oblong groove is arranged along the length of the seedling support crank 24. The movable rod can move up and down along the oblong groove. Rectangular grooves communicating with the oblong groove are provided on the left and right sides of the seedling support crank 24. A short pin 26 passing through the rectangular groove is provided on the movable rod. The short pin 26 can move up and down along the rectangular groove.

[0029] More specifically, the lower fixed plate 27 has a first arc-shaped groove 271, which allows the seedling support rod 25 to rotate along the first arc-shaped groove 271 under the action of the seedling support motor 203 for seedling support. The lower fixed plate 27 is provided with a seedling support motor support member 21 perpendicular to the lower fixed plate 27. The seedling support motor 23 is connected to the seedling support motor support member 21 through the seedling support motor fixing member 22. Both the seedling support motor fixing member 22 and the seedling support motor support member 21 are plate-shaped. Furthermore, the output shaft of the seedling support motor 23 is connected to the seedling support rocker arm 24, which can drive the seedling support rocker arm 24 to rotate. Driven by the mechanism, the connecting plate rotates along the first arc-shaped slide groove 271, which is semi-circular. The two seedling support rods 251 support the seedlings. While supporting the seedlings, the moving rod can move along the waist-shaped through groove, and the short pin shaft 26 can move along the rectangular through groove, thus ensuring the smooth implementation of the seedling support action. The seedling support rod 25 can move within the range of 0°-180°, thus enabling the uprighting operation of the potted seedlings. Based on the different requirements for uprightness of different crops during the potted seedling stage, the angle of movement of the seedling support rod 25 can be adjusted to make it suitable for uprighting potted seedlings of various crops.

[0030] Among them, combined Figure 4 and Figure 5As shown, the second horizontal moving mechanism includes an upper fixed plate 317 connected to the support plate 45, a second drive motor 316 located at the lower end of the upper fixed plate 317, a second lead screw 313 connected to the second drive motor 316, a second lead screw nut 312 located on the second lead screw 313, and a crossbar connected to the second lead screw nut 312. T-shaped members 309 are respectively provided at both ends of the crossbar. The T-shaped members 309 are slidably connected to the upper fixed plate 317. Two second slide rails 311 are provided parallel to the upper fixed plate 317. A second slider 310 is slidably mounted on the second slide rails 311. The T-shaped members 309 on the same side are connected to the second slider 310. The horizontal end of 9 is connected to the second slider 310. The second lead screw 313 is located between the two second slide rails 311 and is parallel to the second slide rails 311. The second lead screw 313 is connected to the output shaft of the second drive motor 316 through the second coupling 314. The second drive motor 316 is connected to the upper fixed plate 317 through the second drive motor connector 315. The second drive motor connector 315 is an L-shaped base plate. As the second drive motor 316 rotates, the soil-carrying mechanism 3 can be driven to perform a small range of linear motion through the action of the second lead screw nut 312, the T-shaped part 309, the second slider 310 and the second slide rail 311.

[0031] Combination Figure 4 and Figure 5 As shown, the soil-collecting mechanism 3 includes an intermediate fixed plate 305 connected to a T-shaped member 309, a drive mechanism and a transmission mechanism disposed on the intermediate fixed plate 305, and two soil-collecting devices 301 linked to the transmission mechanism. The drive mechanism is connected to the transmission mechanism and is used to drive the two soil-collecting devices 301 to move closer or further apart through the transmission mechanism. The intermediate fixed plate 305 is inverted L-shaped and has a second horizontal part and a second vertical part. By setting the second horizontal part and the second vertical part, on the one hand, it is convenient to connect with the T-shaped member 309, and on the other hand, it is convenient to install the drive mechanism and the transmission mechanism. The second horizontal part is fixedly connected to the two T-shaped members 309 respectively, and the drive mechanism and the transmission mechanism are both disposed on the second vertical part.

[0032] The two soil-holding devices 301, when joined, form a funnel shape, and the soil-holding hole formed by the two soil-holding devices 301 is vertically positioned. The soil-holding hole is conical with the larger end facing down and the smaller end facing up. The diameter of the smaller end of the soil-holding hole is larger than the outer diameter of the seedling stem to avoid damage to the seedling stem after the two soil-holding devices 301 are joined. The driving mechanism includes a rotary motor 319, a soil-holding crank 308 connected to the rotary motor 319, and a rocker arm 307 hinged to the soil-holding crank 308. The rotary motor 319 is connected to the intermediate fixed plate through a rotary motor connector 318. 305 is connected, and the rocker arm 307 is connected to the transmission mechanism. During the closing process of the two soil-holding devices 301, the soil carried is covered and compacted at the roots of the potted seedling, thus completing the soil-holding and seedling-stabilizing of the planted seedling. Afterwards, the two soil-holding devices 301 open again to complete the planting of the potted seedling. The vertically set soil-holding holes ensure the uprightness of the planted seedling. The two soil-holding devices 301 after closing are funnel-shaped, which can hold more soil and improve the stability of seedling stabilization. It should be noted that the parts not described in detail in this application are all prior art.

[0033] The transmission mechanism includes a vertical connector 304 and two guide blocks 303. The vertical connector 304 has a vertical part 3041 that slides vertically with the intermediate fixed plate 305. The intermediate fixed plate 305 has two symmetrical fixed blocks 306, and a moving groove for vertical sliding of the vertical part 3041 is formed between the fixed blocks 306. The vertical part 3041 is hinged to the rocker arm 307. Two soil-supporting rods 302 are movably connected to the vertical connector 304. The lower end of the soil-supporting rod 302 passes through the guide block 303 and the end is connected to the soil-supporting device 301. The soil-supporting rod 302 has a limiting rod 3021. Two seedling support rods 251 are located between the two soil-supporting rods 302 and above the two soil-supporting devices 301 after they are joined. The vertical connector 304 has a second arc-shaped sliding groove that slides with the limiting rod 3021. 3042, the two second arc-shaped sliding grooves 3042 are in the shape of the number eight. The guide block 303 is provided with a conical through hole for the soil-supporting rod 302 to pass through. The large end of the conical through hole faces upward and the small end faces downward. The outer wall of the soil-supporting rod 302 is provided with a hemispherical limiting part 3022. The diameter of the soil-supporting rod 302 is smaller than the inner diameter of the small end of the conical through hole. The limiting part 3022 can rotate in the conical through hole. When the vertical connecting piece 304 moves downward, the limiting part 3022 on the soil-supporting rod 302 reaches the conical through hole of the guide block 303, so that the soil-supporting rod 302 can no longer go down and will tilt along the conical through hole. Due to the limiting effect of the guide block 303, the soil-supporting rod 302 is similar to a lever, with the upper end facing outward and the lower end facing inward, causing the two soil-supporting devices 301 to converge inward, realizing soil support and seedling fixation. The frame 1 is provided with a camera 5 facing the straightening mechanism 2.

[0034] The above-mentioned device is controlled by multiple motors. After the transplanter transplants the seedlings, the automatic seedling uprightness and position measurement system can detect multiple data related to the uprightness and position of the seedlings. These data are processed by a computer and converted into position signals that the device needs to move when it is working. The motors are then used to make the device work.

[0035] When this device is in operation, firstly, camera 5 acquires information such as the posture of the seedling, and then the acquired information is uploaded to the computer. The posture information of the seedling is then converted into corresponding signals. Based on the signals received by the computer, each motor can be controlled to perform corresponding operations: the seedling support motor 23 drives the seedling support crank 24 to rotate according to the signal, causing the seedling support rod 25 to rotate accordingly to ensure that the stem of the seedling is positioned between the two seedling support rods 251; then, the first drive motor 48 starts working, driving the straightening mechanism 2 and the soil-supporting mechanism 3 to move laterally (along the direction of the seedling). When the device reaches the designated position, the first drive motor 48 stops working. At this time, the stem of the seedling is located between the two supporting rods 251. The supporting motor 23 rotates again, and the supporting crank 24 drives the supporting rod 205 to rotate along the first arc-shaped slide groove 271. The two supporting rods 251 rotate accordingly until the supporting crank 24 is at 90° with the ground, thus straightening the seedling. At this point, the seedling straightening process ends and the soil covering process begins. The rotary motor 319 also works according to the transmitted signal. The rotary motor 319 drives the crank rocker mechanism to move, thereby driving the vertical movement. The moving part 304 moves linearly, and the downward linear movement of the vertical moving part 304 drives the two soil-supporting rods 302 to move linearly downward as well. When the crank 308 rotates to the horizontal position, the limiting part 3021 of the soil-supporting rod 302 contacts the guide block 303. At this moment, the positions of the soil-supporting rod 302 and the guide block 303 are relatively fixed, and the soil-supporting device 301 contacts the planting ground. As the rotary motor 319 continues to rotate, the vertical connecting part 304 continues to move downward. However, since the guide block 303 is fixed on the intermediate fixed plate 305, the upper end of the soil-supporting rod 302 will slide along the second arc-shaped groove 3. 042 slides to both sides, and the lower ends converge to compact the soil. When the rocker arm 307 is rotated to the lowest point, the two soil compactors 301 close together, and the soil around the seedling is compacted under the action of the soil compactors 301, keeping the seedling upright. Then, as the rotary motor 319 continues to rotate, the soil compaction crank 308 begins to rotate, the soil compactors 301 slowly disperse, and the soil compaction rod 302 slowly returns to a vertical position. As the rotary motor 319 continues to rotate, the vertical connecting piece 304 also gradually rises, completing one soil compaction process. The number of soil compaction cycles can be set manually. After all processes are completed, the first drive motor 48 rotates in the opposite direction, driving the entire mechanism back to its initial position. During mechanical transplanting, due to human operation and other factors, the seedlings in pots are not always planted in a straight line and may have some deviation. Therefore, when compacting the soil, the position of the soil compacting mechanism 3 can be adjusted by the second drive motor 316 to ensure that the seedling in the pot is in the center after the soil compactor 301 closes, so as to prevent the soil compactor 301 from damaging the seedling.

[0036] This application requires the ability to straighten seedlings that are not upright or have fallen over after planting, based on the detection data of the uprightness of the seedlings and the location information of the seedlings. This will increase the survival rate of the seedlings after planting, avoid losses, and greatly reduce the labor intensity of manual seedling straightening, reduce labor costs, and increase profits.
