Description

Technical Field

[0001] This invention belongs to the field of water management and planting technology, and in particular relates to a lotus replanting device. Background Technology

[0002] Lotus, belonging to the order Proteales and family Nelumbo, is a general term for two species in the genus Nelumbo, namely "lotus" and "yellow lotus," as well as numerous artificially cultivated varieties. It is a perennial aquatic herbaceous flowering plant. The lotus has a long, thick underground stem with long nodes. Its leaves are shield-shaped. Flowering occurs from June to September, with a single flower bud at the top of the peduncle. The flower has numerous petals embedded in the receptacle, and comes in colors such as red, pink, white, and purple, sometimes with variegated patterns or borders. The nut is oval, and the seeds are egg-shaped. Lotus flowers can be divided into two main categories: ornamental and edible. The rhizome and seeds are edible, and the seeds, rhizome, rhizome nodes, leaves, flowers, and seed embryos are all used in traditional medicine. Ornamental lotus flowers can be planted in pots, jars, or in lakes and other bodies of water. For ornamental lotus flowers in lakes and other water bodies, replanting before the annual flowering season is necessary. Replanting here refers to adding a certain number of lotus flowers to areas with sparse lotus leaves before the flowering season. The replanted lotus flowers include underground stems (rhizome rhizomes), adventitious roots (growing on the underground stems and being very thin; the fine tendrils on the rhizome nodes are adventitious roots), lateral leaves, floating leaves, etc., and may include lateral rhizomes, upright leaves, lateral leaves, and cotyledons, but not flowers. In other words, the replanted lotus flowers mainly consist of rhizomes and several lotus leaves (actually, adventitious roots are also included, but since they grow on the rhizomes and are very thin, they have little impact on the replanting operation and are therefore not emphasized).

[0003] Additional explanation: When the terminal bud of the lotus root sprouts, it produces the first leaf, which does not emerge from the water and is called the "coin leaf." After the coin leaf, a slender rhizome grows forward from the terminal bud, called the "lotus whip." Fibrous roots develop at the nodes of the lotus whip, and leaves grow upwards, floating on the water surface; these are called "floating leaves." After the lotus whip grows to a certain length, the leaves growing upwards from the nodes have thick petioles, and the leaves at the top of the petioles emerge above the water surface; these are called "standing leaves." When the lotus whip thickens to form a new lotus root, the last large leaf emerges upwards; this is called the "posterior leaf." When the lotus whip thickens to form a new lotus root, a small, thick leaf emerges in front of it; this is called the "cotyledon." The rhizome (lotus root or lotus whip) of the lotus grows horizontally, with swollen and thickened internodes, and fibrous adventitious roots underneath.

[0004] Each area to be replanted typically has multiple replanting locations. The existing replanting process is as follows: Step 1, workers transport the lotus flowers (which need to be pre-cultivated, as mentioned earlier, including rhizomes and several lotus leaves, without flowers, as will be discussed later) to the vicinity of the replanting location in the water using a small boat; Step 2, workers use shovels and other tools to dig planting pits in the underwater mud at the replanting location, large enough to hold the rhizomes; Step 3, workers manually place the rhizomes into the planting pits, then cover them with some mud using a shovel to prevent them from becoming unstable in the water or shifting with the current or waves; Step 4, a small amount of immediate fertilizer is applied, such as a potassium dihydrogen phosphate solution or compound fertilizer granules in the water at the replanting location. After replanting, topdressing can be applied periodically as needed, either as foliar fertilizer or by applying fertilizer to the water. During the replanting process, there is often a step of applying base fertilizer. This step can be set after step two. The method is to apply solid base fertilizer (usually slow-release or controlled-release fertilizer) into the planting pit, and then cover the base fertilizer in the planting pit with a layer of soil. Then, step three can be carried out. In the above replanting process, step two is the "digging pit, placing the rhizome, and covering with soil" step. This step can also be done using the "pot pressing method". That is, the lotus to be replanted is pre-cultivated in a pot. At least two workers put the lotus along with the pot into the water to contact the soil, and then press the pot down until a planting pit is made. Then, the lotus to be replanted is separated from the pot in the water. After removing the pot, the rhizome of the lotus to be replanted is placed into the planting pit, and then some soil is covered on the rhizome. This also completes the "digging pit, placing the rhizome, and covering with soil" step.

[0005] The existing replanting process has several shortcomings: First, digging planting pits is difficult because lotus rhizomes are usually planted in the mud 60 to 100 centimeters underwater. Therefore, digging pits relies on intuition, making it difficult to accurately determine the depth and length. Second, workers need to manually place the rhizomes into the underwater planting pit. Since the average person's arm length is limited, this process often involves diving (the worker's face needs to be submerged), holding their breath, and putting their head underwater to reach the pit. This inevitably leads to contact between the worker's face and the not-so-clean water. Third, the step of "covering the rhizomes with more mud" in step three usually requires using shovels or other tools to move surrounding mud into the planting pit. Because the underwater environment is not visible, this can easily damage the rhizomes. Damage to the rhizomes allows water to enter through the pores, leading to rot. If the surrounding mud is moved by hand, workers need to dive multiple times, significantly increasing the difficulty and reducing efficiency. Furthermore, if the "basin pressing method" described above is used, it is unavoidable that the worker's face will be immersed in water multiple times. Summary of the Invention

[0006] This invention provides a lotus replanting device that can simply and efficiently assist workers in digging planting holes in the underwater mud at the replanting location. This allows the lotus rhizomes to accurately enter the planting holes, and the process of the rhizomes entering the planting holes and the subsequent covering with soil does not require workers to put their hands into the underwater mud, thus avoiding the risk of workers' faces getting wet. In addition, the operation of covering the rhizomes with soil does not require the use of a shovel, and will not damage the rhizomes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lotus replanting device includes a vertically placed main insert plate, a mud-pulling plate that can rotate relative to the main insert plate, a side frame that is fixed to the main insert plate and placed horizontally, a planting plate located at the lower end of the side frame, and a steel cable for pulling the mud-pulling plate to rotate.

[0009] One surface of the main insert plate is the main working surface, one surface of the mud-removing plate is the mud-removing surface, and the other surface of the mud-removing plate is the contact surface. A hinge seat is provided on the main working surface, and a horizontally placed hinge shaft is rotatably connected to the hinge seat. The hinge shaft and the hinge seat are damped and self-locked. The mud-removing plate is connected to the hinge shaft. The mud-removing plate is provided with a long passage for the lotus root whip and lotus leaf to pass through. The long passage penetrates the two surfaces of the mud-removing plate.

[0010] One side of the side frame is fixed to the main working surface, the seeding plate is hinged to the side frame, and the seeding plate can be snapped into the side frame. The side frame is provided with a guide cable hole, the main insert plate is provided with a limiting cable hole, the seeding plate is located between the axis of the guide cable hole and the main working surface, one end of the steel cable is fixed to the mud removal surface, the other end of the steel cable is provided with a pull ring, and the steel cable passes through the guide cable hole and the limiting cable hole.

[0011] When the contact surface is in contact with the main working surface: the mud-removing plate is vertical, and the upper part of the main insert plate, the limiting cable hole, the side frame, the upper part of the mud-removing plate, the long passage, the lower part of the mud-removing plate and the lower part of the main insert plate are arranged in order from top to bottom.

[0012] Preferably, the main insert plate has a downward-facing cutting edge at its lower end, several hammer bases at its top, and several handle holes on its main insert plate. The handle holes penetrate both surfaces of the main insert plate. When the contact surface is in contact with the main working surface, the lower surface of the mud-removing plate is an inclined surface, and the distance between the lower surface of the mud-removing plate and the main working surface gradually decreases from top to bottom.

[0013] Preferably, the side frame is a rectangular frame, comprising two parallel long frame rods and two parallel short frame rods. The long frame rods are perpendicular to the short frame rods. One long frame rod is the near rod, and the other long frame rod is the far rod. The near rod is attached to and fixed to the main working surface. The seeding plate is hinged to the far rod. The axis of rotation of the seeding plate relative to the far rod is parallel to the main working surface. The guide cable hole is located on the far rod, and the axis of the guide cable hole is vertical. The end of the steel cable fixed to the mud-removing surface is the lower cable head end. When the contact surface is attached to the main working surface: the vertical distance between the lower cable head end and the top of the mud-removing plate is M, and the vertical distance between the lower cable head end and the bottom of the mud-removing plate is N, where M is greater than 5N.

[0014] Preferably, the seeding plate can be snapped into the side frame via a snap-fit ​​structure. The snap-fit ​​structure includes a snap head on the seeding plate and a snap groove on the side frame. The snap head and the snap groove are adapted to each other. When the seeding plate is in a horizontal position and the lower end of the side frame is sealed, the snap head is snapped into the snap groove.

[0015] Preferably, the side frame is provided with a vertical lifting rod for opening the seeding plate. The vertical lifting rod is slidably connected to the side frame and is damped and self-locked with the side frame. The vertical lifting rod slides vertically and slides in contact with the main working surface. When the lower end of the vertical lifting rod is in contact with the top surface of the seeding plate, the seeding plate is in a horizontal position and the lower end of the side frame is sealed.

[0016] Preferably, the steel cable is provided with a pressing bead that can contact and press down on the top surface of the vertical start rod. The axis of the limiting cable hole is perpendicular to the main working surface. The diameter of the pressing bead is r. The distance between the top surface of the vertical start rod and the axis of the limiting cable hole is L. The diameter of the limiting cable hole is R, R>r, L<r.

[0017] When the steel cable is under tension and the lower pressure bead contacts the top surface of the vertical starter rod: the angle between the mud-dispensing plate and the vertical insertion plate is greater than or equal to 80 degrees, the angle between the mud-dispensing plate and the vertical insertion plate is less than or equal to 90 degrees, and the distance between the mud-dispensing surface and the main working surface gradually increases from top to bottom.

[0018] Preferably, the diameter of the guide cable hole is larger than the diameter of the pressure bead, and the main insert plate is provided with a groove that opens on the main working surface. The pressure bead can be engaged with the groove. The part of the steel cable between the pressure bead and the end of the lower cable is the end section cable, and the remaining part of the steel cable is the front section cable. When the contact surface is in contact with the main working surface and the pressure bead is engaged with the groove, the end section cable is in a tensioned state.

[0019] Preferably, the main insert plate is provided with a pre-fertilizer channel, and the limiting cable hole is connected to the pre-fertilizer channel. The pre-fertilizer arrangement channel includes a vertical channel and a sliding channel. One end of the sliding channel is the fertilizer receiving end, and the other end of the sliding channel is the fertilizer supply end. The upper end of the vertical channel opens to the top surface of the main insert plate, and the lower end of the vertical channel is connected to the fertilizer receiving end. The fertilizer supply end opens to the main working surface. When the contact surface is in contact with the main working surface: the mud-removing plate blocks the fertilizer supply end, and the hinge shaft, the long through port, and the fertilizer supply end are arranged in sequence from top to bottom.

[0020] Preferably, the side frame is provided with a limiting block for the seed fixing plate. When the seed fixing plate contacts the limiting block, the seed fixing plate is in a vertical state.

[0021] The steel cable is equipped with a limiting bead for limiting the mud-dispelling plate. The limiting bead is located below the side frame. The diameter of the limiting bead is larger than the diameter of the guide cable hole. When the limiting bead contacts the side frame, the seed plate forms an angle of 30 to 60 degrees with the horizontal plane, and the distance between the mud-dispelling surface and the main working surface gradually decreases from top to bottom.

[0022] The beneficial effects of this invention are: it can simply and efficiently assist workers in digging planting holes in the underwater mud at the replanting location, allowing the lotus rhizomes to accurately enter the planting holes. Furthermore, the process of the rhizomes entering the planting holes and the subsequent covering with soil does not require workers to put their hands into the underwater mud, thus avoiding water damage to their faces. Additionally, the covering of the rhizomes does not require a shovel, preventing damage to the rhizomes. When digging planting pits, it can automatically recognize when the pits have been dug and subsequently open the planting plate to allow the rhizomes to enter. It has a pre-fertilizer channel that can accurately supply solid base fertilizer to the planting pits and automatically cover the solid base fertilizer with soil, ensuring that the solid base fertilizer is not washed away by water flow and preventing direct contact with the rhizomes from burning the seedlings.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, a lotus replanting device includes a vertically placed main insert plate 1, a mud-pulling plate 2 that can rotate relative to the main insert plate 1, a side frame 3 that is fixed to the main insert plate 1 and placed horizontally, a planting plate 4 located at the lower end of the side frame 3, and a steel cable 5 for pulling the mud-pulling plate 2 to rotate.

[0038] One surface of the main insert plate 1 is the main working surface 1.1, one surface of the mud-removing plate 2 is the mud-removing surface 2.1, and the other surface of the mud-removing plate 2 is the contact surface 2.2. A hinge seat 101 is provided on the main working surface 1.1, and a horizontally placed hinge shaft 102 is rotatably connected to the hinge seat 101. The hinge shaft 102 and the hinge seat 101 are damped and self-locked. The mud-removing plate 2 is connected to the hinge shaft 102. The mud-removing plate 2 is provided with a long passage 2a for the lotus root whip and lotus leaf to pass through. The long passage 2a passes through both surfaces of the mud-removing plate 2.

[0039] One side of the side frame 3 is fixed to the main working surface 1.1. The seeding plate 4 is hinged to the side frame 3 and can be snapped into the side frame 3. The side frame 3 is provided with a guide cable hole 3a, and the main insert plate 1 is provided with a limiting cable hole 1a. The seeding plate 4 is located between the axis of the guide cable hole 3a and the main working surface 1.1. One end of the steel cable 5 is fixed to the mud-removing surface 2.1, and the other end of the steel cable 5 is provided with a pull ring 501. The steel cable 5 passes through the guide cable hole 3a and the limiting cable hole 1a.

[0040] When the contact surface 2.2 is in contact with the main working surface 1.1: the mud-removing plate 2 is vertical, and the upper end of the main insert plate 1, the limiting cable hole 1a, the side frame 3, the upper end of the mud-removing plate 2, the long passage 2a, the lower end of the mud-removing plate 2 and the lower end of the main insert plate 1 are arranged in order from top to bottom.

[0041] The mud-removing plate 2 is connected to the hinge shaft 102 via several connecting rods 201. The main insert plate 1 has two surfaces, one of which is the main working surface 1.1. The mud-removing plate 2 has two surfaces, one of which is the mud-removing surface 2.1 and the other is the contact surface 2.2.

[0042] When replanting lotus flowers is needed, workers row a small boat to the replanting location. The workers are on the boat, and the lotus flowers to be replanted are also on the boat. The invention is then placed in water. At this point, the mud-removing plate 2 is vertical, and the workers' bodies and the mud-removing plate 2 are positioned on opposite sides of the main insert plate 1. The main insert plate 1 is pressed down so that its lower end inserts into the underwater mud. After insertion, the hinge seat 101 is also in the mud. At this time, the planting plate 4 engages with the side frame 3, and the position of the planting plate 4 is as follows... Figure 1 , Figure 2 , Figure 8 As shown in the diagram. Place a lotus rhizome on the planting board 4, with the petiole of the lotus leaf upright and the lotus leaf above the rhizome, making sure the length of the rhizome is parallel to the hinge shaft 102. Note that the steel cable 5 above the side frame 3 should be positioned between the petioles of the two lotus leaves, and should not press down on the lotus leaves (some lotus leaves may be higher than the position of the steel cable 5).

[0043] The worker holds the main insert plate 1 with one hand and pulls the pull ring 501 with the other hand to pull the steel cable 5 (or one worker holds the main insert plate 1 and the other worker holds the pull ring 501 to pull the steel cable 5). Since one end of the steel cable 5 is fixed to the mud-removing surface 2.1, the steel cable 5 will cause the mud-removing plate 2 to start rotating upward along the hinge shaft 102, and the long passage 2a will also rotate with the mud-removing plate 2. At a certain moment, the mud-removing plate 2 rotates to a horizontal or near-horizontal position (e.g., Figure 10 As shown in the diagram, at this point, the mud-removing plate 2 has not completely left the soil, meaning there is still soil above the mud-removing plate 2. During the above process, the soil near the bottom of the long passage opening 2a will be pushed outward by the mud-removing plate 2. When the mud-removing plate 2 rotates to a horizontal or near-horizontal position, the long passage opening 2a also rotates to a horizontal or near-horizontal position. At this time, the long passage opening 2a is roughly directly below the side frame 3, and a planting pit dug out by the mud-removing plate 2 will be formed near the bottom of the long passage opening 2a.

[0044] It should be noted that during the process of digging the planting pit with the mud-removing board 2, the soil directly above the long passage 2a will fall through the long passage 2a and replenish the planting pit. Therefore, after the planting pit is dug, there is basically no soil directly above the long passage 2a, while there is still soil above the solid part of the mud-removing board 2. In addition, some soil on the side of the planting pit will be squeezed from the outside into the planting pit and replenish it. However, the amount of soil replenished to the planting pit is less than the amount of soil that the mud-removing board 2 removes, so the planting pit can still exist. Furthermore, the soil for planting lotus flowers is relatively close to the state of "silt" (i.e., not particularly compact or hard soil), so the force required to dig the planting pit is not particularly large, and the mud-removing board 2 can dig the planting pit smoothly. When pulling the steel cable 5, it is not necessarily necessary to hold the main insertion plate 1. If the main insertion plate 1 is relatively stable after being inserted into the soil, it is not necessary to hold the main insertion plate 1. Furthermore, the limiting cable hole 1a restricts the pull ring 501, preventing the pull ring 501 from passing through the limiting cable hole 1a and reaching the side where the side frame 3 is located.

[0045] As mentioned earlier, the planting board 4 is hinged to the side frame 3, and the planting board 4 can also be snapped into the side frame 3. In fact, the planting board 4 is snapped into the side frame 3 from the beginning. After the planting pit is dug, the planting board 4 is loosened so that the planting board 4 is no longer snapped into the side frame 3. The planting board 4 rotates and falls down, and the lotus flowers on the planting board 4 fall into the water. Then, the lotus rhizomes enter the planting pit through the long passage 2a, while the lotus leaves are above the long passage 2a, with the petioles of the lotus leaves passing through the long passage 2a.

[0046] The worker continues to pull the steel cable 5 through the pull ring 501, and the mud-dispensing plate 2 continues to rotate until the end of the mud-dispensing plate 2 away from the hinge shaft 102 leaves the water surface. The mud-dispensing plate 2 will then reach a state where the long passage 2a is in a relatively low position, the solid part of the mud-dispensing plate 2 is in a relatively high position, and the mud-dispensing surface 2.1 is tilted (e.g., Figure 12As shown in the diagram, during this process, the soil above the solid part of the mud-removing board 2 will move down along the mud-removing surface 2.1 of the mud-removing board 2. A large portion of it will fall through the long passage 2a into the planting pit and cover the lotus rhizome, thus completing the lotus rhizome covering operation. Afterwards, if necessary, some immediate fertilizer can be applied to the water, such as a potassium dihydrogen phosphate solution or compound fertilizer granules. Through the above process, a lotus replanting process is completed. At this time, there is basically no soil or very little soil above the mud-removing board 2. The main insert 1 and the mud-removing board 2 can be pulled upwards out of the water (when pulling upwards out of the water, the positions of the mud-removing board 2 and the main insert 1 remain basically unchanged). During the upward pulling out of the water, although the lotus leaves themselves do not move, the long passage 2a moves upwards, and the lotus leaves move downwards relative to the long passage 2a and pass through the long passage 2a, ultimately remaining at the replanting location. Afterwards, by resetting the mud-removing plate 2, the main insert plate 1 can be inserted into the next replanting arrangement, and the aforementioned operation can be repeated to continue replanting lotus flowers.

[0047] As can be seen from the above, when using this invention to replant lotus flowers, workers can operate the entire process from the small boat without even leaving the boat. First, the process of digging planting pits is much simpler. Since the size and relative height of the mud-pulling plate 2 are pre-set, it ensures that the dug planting pits are complete and sufficient, avoiding some problems that may occur when digging planting pits with a shovel, such as insufficient or excessive pit depth or length (these problems are easily caused by digging by feel without seeing the underwater soil). Second, when the lotus rhizome is placed into the planting pit, it can be accurately positioned by the automatic guidance of the side frame 3 and the long passage 2a. Workers do not need to hold the lotus rhizome by hand and place it into the underwater planting pit by feel. Workers' hands do not need to operate on the underwater soil for a long time, and their faces do not need to be submerged in water, significantly reducing the difficulty of operation and ensuring hygiene and safety. Furthermore, the operation of covering the lotus rhizome with soil is also achieved by pulling the steel cable 5 to tilt the mud-pulling plate 2. It is no longer necessary to use a shovel to push some of the surrounding soil into the planting pit, thus avoiding the situation where the shovel damages the lotus rhizome (once the lotus rhizome is damaged, water enters the pores, and it will rot later). Therefore, this invention not only reduces the operational difficulty of replanting lotus flowers, but also significantly improves the efficiency and effect of replanting.

[0048] Several points need to be explained:

[0049] First, how to ensure that the main insert plate 1 is inserted into the soil at the appropriate depth? For example, this can be determined according to the water depth of the replanting area. Suppose that the main insert plate 1 needs to be inserted into the soil 20 cm deep and the water depth is 60 cm. Then, make the first mark 80 cm away from the bottom of the main insert plate 1. Each time the main insert plate 1 is inserted into the soil, the insertion can be stopped when the first mark reaches the water surface.

[0050] Secondly, how can we ensure that the steel cable 5 can rotate the mud-removing plate 2 to a horizontal or near-horizontal position when the underwater conditions are not clearly visible? For example, before the first operation, the main insertion plate 1 can be made vertical on land, and the steel cable 5 can be pulled to make the mud-removing plate 2 horizontal. Then, a second mark can be made on the steel cable 5, and a third mark can be made on the main insertion plate 1 that is close to or even adjacent to the second mark. After that, when the main insertion plate 1 is inserted into the mud, the worker only needs to pull the steel cable 5 to make the second mark close to the third mark, which will ensure that the mud-removing plate 2 rotates to a horizontal or near-horizontal position.

[0051] Thirdly, why can the mud-removing plate 2 remain stationary after being rotated to the desired position? This is because, as mentioned earlier, "the hinge shaft 102 and the hinge seat 101 are rotatably connected, and there is a damping self-locking between the hinge shaft 102 and the hinge seat 101." Also, when necessary, during operation, the worker can pull the steel cable 5 to help maintain the position (the worker pulling the steel cable 5 to help maintain the position of the mud-removing plate 2 is not mandatory, but an operation that can be performed when necessary).

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 9 As shown, the main insert plate 1 has a downward-facing cutting edge 103 at its lower end, and several hammer blocks 104 at its top. The main insert plate 1 has several handle holes 1b, which penetrate the two surfaces of the main insert plate 1. When the contact surface 2.2 is in contact with the main working surface 1.1, the lower surface of the mud-removing plate 2 is an inclined surface, and the distance between the lower surface of the mud-removing plate 2 and the main working surface 1.1 gradually decreases from top to bottom.

[0053] This design aims to further reduce the difficulty of inserting the main insert plate 1 into underwater mud. The cutting edge 103 reduces the obstruction encountered during insertion. The lower surface of the mud-removing plate 2 is an inclined plane, and the distance between the lower surface of the mud-removing plate 2 and the main working surface 1.1 gradually decreases from top to bottom, all to reduce the obstruction encountered when the mud-removing plate 2 enters the mud. Furthermore, if necessary, a tool hammer can be used to strike the hammer block 104 to help the main insert plate 1 insert into the mud. The handle hole 1b facilitates gripping and supporting the main insert plate 1.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8As shown, the side frame 3 is a rectangular frame, including two parallel long frame rods and two parallel short frame rods 301. The long frame rods are perpendicular to the short frame rods 301. One of the long frame rods is the near rod 302, and the other long frame rod is the far rod 303. The near rod 302 is attached to and fixed to the main working surface 1.1. The seeding plate 4 is hinged to the far rod 303. When the seeding plate 4 rotates relative to the far rod 303, the axis of rotation is parallel to the main working surface 1.1. The guide cable hole 3a is set on the far rod 303, and the axis of the guide cable hole 3a is vertical. The end of the steel cable 5 that is fixed to the mud-removing surface 2.1 is the lower cable head end. When the contact surface 2.2 is attached to the main working surface 1.1: the vertical distance between the lower cable head end and the top of the mud-removing plate 2 is M, and the vertical distance between the lower cable head end and the bottom of the mud-removing plate 2 is N. M is greater than 5N.

[0055] The steel cable 5 passes through the guide cable hole 3a. The guide cable hole 3a is located on the far rod 303, making it easier for the worker to pull the steel cable 5 (compared to when the guide cable hole 3a is located on the near rod 302). The vertical distance M between the lower cable end and the top of the mud-removing plate 2, and N between the lower cable end and the bottom of the mud-removing plate 2, where M is greater than 5N, is to ensure the lower cable end is positioned lower and further from the hinge pin 102, thus also making it easier for the worker to pull the steel cable 5 (compared to when the lower cable end is higher and closer to the hinge pin 102).

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 11 As shown, the seeding plate 4 can be snapped into the side frame 3 via a snap-fit ​​structure. The snap-fit ​​structure includes a snap head 401 on the seeding plate 4 and a snap groove 3b on the side frame 3. The snap head 401 and the snap groove 3b are adapted to each other. When the seeding plate 4 is in a horizontal position and the lower end of the side frame 3 is sealed, the snap head 401 is snapped into the snap groove 3b.

[0057] The side frame 3 is provided with a vertical lifting rod 6 for opening the seed plate 4. The vertical lifting rod 6 is slidably connected to the side frame 3. The vertical lifting rod 6 and the side frame 3 are damped and self-locked. The vertical lifting rod 6 slides vertically and slides in contact with the main working surface 1.1. When the lower end of the vertical lifting rod 6 is in contact with the top surface of the seed plate 4, the seed plate 4 is in a horizontal position and the lower end of the side frame 3 is sealed.

[0058] As mentioned earlier, the worker is on the small boat, with his body and the mud-removing plate 2 positioned on opposite sides of the main insert plate 1. That is, the worker's body and the seed-setting plate 4 are positioned on opposite sides of the main insert plate 1. Originally, when it was necessary to loosen the seed-setting plate 4 and de-lock it from the side frame 3, the worker needed to reach over the vertical insert plate to press down on the seed-setting plate 4. However, in this design, the worker can simply reach over the vertical insert plate and press down on the vertical lifting lever 6 to open the seed-setting plate 4. Clearly, the vertical lifting lever 6 is closer to the hand than the seed-setting plate 4 and is easier to operate.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 11 As shown, the steel cable 5 is provided with a pressing bead 502 that can contact and press down the top surface of the vertical lifting rod 6. The axis of the limiting cable hole 1a is perpendicular to the main working surface 1.1. The diameter of the pressing bead 502 is r. The distance between the top surface of the vertical lifting rod 6 and the axis of the limiting cable hole 1a is L. The diameter of the limiting cable hole 1a is R, R>r, L<r.

[0060] When the steel cable 5 is under tension and the lower pressure bead 502 contacts the top surface of the vertical starter rod 6: the angle between the mud-pushing plate 2 and the vertical insert plate is greater than or equal to 80 degrees, the angle between the mud-pushing plate 2 and the vertical insert plate is less than or equal to 90 degrees, and the distance between the mud-pushing surface 2.1 and the main working surface 1.1 gradually increases from top to bottom.

[0061] After the planting pit is dug, the mud-removing plate 2 is rotated to a horizontal or near-horizontal position before the planting plate 4 is released to allow the lotus rhizome to fall into the planting pit. In manual operation, because it is a step-by-step operation, mistakes are inevitable (such as "releasing the planting plate 4 before the planting pit is dug properly").

[0062] In this solution, the step-by-step operation is eliminated. The operation of "digging the planting pit first and then releasing the seeding plate 4" is achieved directly by pulling the steel cable 5. Specifically, initially, the seeding plate 4 is horizontal and locked to the side frame 3. The lower end of the vertical lifting rod 6 contacts the top surface of the seeding plate 4. The worker pulls the steel cable 5 to rotate the mud-pulling plate 2 to dig the planting pit. When the mud-pulling plate 2 rotates to a horizontal or near-horizontal position (in this solution, the mud-pulling plate 2 rotates more than 80 to 90 degrees, but this can be set according to specific needs), the downward pressure bead 502 on the steel cable 5 also reaches the limit cable hole 1a and contacts the top surface of the vertical lifting rod 6. Since the limit locking hole is partially blocked by the vertical lifting rod 6 at this time, the downward pressure bead 502 cannot enter and pass through the limit cable hole 1a. Therefore, as the worker continues to pull the steel cable 5, the downward pressure bead 502 directly presses down on the vertical lifting rod 6, thereby opening the seeding plate 4 through the vertical lifting rod 6. During the above process, only when the mud-pulling plate 2 is rotated to a horizontal or near-horizontal position will the pressure bead 502 reach a position that can press down the vertical lifting rod 6 and open the seed-fixing plate 4, thus ensuring that "the planting pit is dug first and then the seed-fixing plate 4 is released", and preventing the situation of "the planting pit is not dug properly and the seed-fixing plate 4 is released" due to worker misoperation.

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the diameter of the guide cable hole 3a is larger than the diameter of the pressure bead 502. The main insert plate 1 is provided with a groove 1c that opens on the main working surface 1.1. The pressure bead 502 can be engaged with the groove 1c. The part of the steel cable 5 between the pressure bead 502 and the end of the lower cable is the end section cable 5.1, and the remaining part of the steel cable 5 is the front section cable 5.2. When the contact surface 2.2 is in contact with the main working surface 1.1 and the pressure bead 502 is engaged with the groove 1c, the end section cable 5.1 is in a tensioned state.

[0064] When the main insert plate 1 is inserted into the soil, a portion of the front section 5.2 of the steel cable 5 also needs to enter the soil. In this design, before inserting the main insert plate 1, the pressure bead 502 can be positioned in the groove 1c. This keeps the rear section 5.1 taut and allows it to better align with the main working surface 1.1. Consequently, when the main insert plate 1 is inserted into the soil, the resistance experienced by the front section 5.2 of the steel cable 5 is reduced, making the insertion process smoother. When the steel cable 5 is pulled subsequently, the pressure bead 502 will naturally disengage from the groove 1c, without affecting subsequent work. Furthermore, the diameter of the guide cable hole 3a is larger than the diameter of the pressure bead 502, allowing the pressure bead 502 to pass through the guide cable hole 3a.

[0065] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 12 As shown, the main insert plate 1 is provided with a pre-fertilizer channel 1.2, and the limiting cable hole 1a is connected to the pre-fertilizer channel 1.2. The pre-fertilizer arrangement channel includes a vertical channel 1.2a and a sliding channel 1.2b. One end of the sliding channel 1.2b is the fertilizer receiving end, and the other end of the sliding channel 1.2b is the fertilizer supply end. The upper end of the vertical channel 1.2a opens to the top surface of the main insert plate 1, and the lower end of the vertical channel 1.2a is connected to the fertilizer receiving end. The fertilizer supply end opens to the main working surface 1.1. When the contact surface 2.2 is in contact with the main working surface 1.1: the mud-removing plate 2 blocks the fertilizer supply end, and the hinge shaft 102, the long through port 2a, and the fertilizer supply end are arranged sequentially from top to bottom.

[0066] Background technology states that, "During replanting, there is often a step of applying base fertilizer. This step can be set after step two. The method involves applying solid base fertilizer (usually slow-release or controlled-release fertilizer) into the planting pit, then covering the base fertilizer with a layer of soil, and then proceeding to step three." Generally, applying base fertilizer is necessary because the area to be replanted has sparse lotus leaves, clearly indicating insufficient soil fertility. However, it is important to note that the base fertilizer should not come into direct contact with the lotus rhizome, as this can easily burn the seedlings (short-term contact of the rhizome with excessively concentrated fertilizer can burn the seedlings). Therefore, a layer of soil is usually placed between the base fertilizer and the lotus rhizome to allow the base fertilizer to release its nutrients slowly.

[0067] In this scheme, before digging the planting pit, an appropriate amount of solid base fertilizer (usually slow-release or controlled-release fertilizer) is directly added into the vertical channel 1.2a of the pre-fertilization channel 1.2. The solid base fertilizer will reach the fertilizer supply end of the sliding channel 1.2b, but is blocked by the mud-removing plate 2. Then, when the mud-removing plate 2 rotates to start digging the planting pit, the solid base fertilizer will fall into the planting pit. As mentioned earlier, "during the process of the mud-removing plate 2 digging the planting pit, the soil directly above the long passage 2a will fall through the long passage 2a and replenish the planting pit," and "a part of the soil on the side of the planting pit will be squeezed from the outside into the planting pit and replenish the planting pit." Therefore, the soil replenished to the planting pit will automatically cover the solid base fertilizer that has fallen into the planting pit, accurately "locking" the base fertilizer in the planting pit area, making the fertilizer supply more accurate and reducing waste. In this way, after the lotus rhizomes are placed in the planting pit, there is soil separating the rhizomes from the solid base fertilizer. The solid base fertilizer can slowly release nutrients to help the lotus (lotus rhizomes, lotus leaves, etc.) grow smoothly, so that when the flowering period arrives, it will be easier to bloom smoothly.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 11 As shown, the side frame 3 is provided with a limiting block 304304 for limiting the seed fixing plate 4. When the seed fixing plate 4 contacts the limiting block 304, the seed fixing plate 4 is in a vertical state.

[0069] The steel cable 5 is provided with a limiting bead 503 for limiting the mud-removing plate 2. The limiting bead 503 is located below the side frame 3. The diameter of the limiting bead 503 is larger than the diameter of the guide cable hole 3a. When the limiting bead 503 contacts the side frame 3, the seed plate 4 forms an angle of 30 to 60 degrees with the horizontal plane, and the distance between the mud-removing surface 2.1 and the main working surface 1.1 gradually decreases from top to bottom.

[0070] The limiting block 304 can restrict the position of the planting plate 4 to prevent it from shaking outwards, and thus better restrict the channel position when the lotus rhizome falls, ensuring that the lotus rhizome enters the planting pit smoothly. After the limiting bead 503 contacts the side frame 3, it can restrict the angle of the planting plate 4 to prevent the planting plate 4 from rotating excessively or flipping upwards and damaging the lotus leaves and petioles.

[0071] The embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
