[0016] The present invention also discloses a method for using the portable rice seedling-replenishing machine, comprising:

[0017] Step S1: Gd seedlings and seedling loading:

[0018] After using the seedling clamp to clamp the seedling block, use a fruit knife to cut the seedlings;

[0019] The power connecting rod is squeezed by hand to move up and down, and the seedling tray is moved to the leftmost or rightmost end, and then the seedling block is installed on the seedling tray, and the seedling clamp of the seedling block pushing rod is pulled to the front end of the seedling tray, and the hook of the seedling clamp is hooked on the front end of the seedling tray. After the hook is pulled up, two tension springs pull the seedling block pushing rod back at the same time until the seedling clamp is pulled back to the initial position by the seedling block pushing rod, and the seedling clamp hook just clamps the seedling block on the seedling tray, and the seedling loading is completed;

[0020] Step S2: carrying the rice transplanting pole to the place where the rice seedlings are missing to complete the one-hole transplanting, specifically including the following steps:

[0021] The transplanting rod is pressed down, and the transplanting needle cuts the seedlings from the seedling block and inserts the clamped seedlings through the transplanting opening into the seedling field;

[0022] The transplanting rod is lifted, and the transplanting needle rises and passes through the transplanting opening. At the same time, the active contact of the transplanting rod contacts the driven contact of the power connecting shaft and pushes the driven contact to rise, thereby driving the power connecting shaft and the power connecting rod to rise; during the rising process of the power connecting rod, the power connecting rod transmits power to the power input joint. If the direction rod is in the left movement gear, the power converter controls the sprocket shaft to rotate, drives the sprocket to rotate, and the sprocket transmits power to the chain, and the chain moves the seedling tray to the left in a straight line; if the direction rod is in the right movement gear, the power converter controls the sprocket shaft to rotate, drives the sprocket to rotate, and the sprocket transmits power to the chain, and the chain moves the seedling tray to the right in a straight line;

[0023] Step S3: Repeat step S2. When the chain moves the seedling tray to the right to the rightmost end, the left return control lever touches the direction lever, causing the direction lever to change to the left movement gear. Conversely, when the chain moves the seedling tray to the left to the leftmost end, the right return control lever touches the direction lever, causing the direction lever to change to the right movement gear. After all the seedlings in the seedling tray are planted, repeat step S1 to plant and load the seedlings, and repeat step S2 to continue seedling filling until all seedling filling is completed.

[0024] The beneficial effects of the present invention are:

[0025] The invention discloses a portable rice seedling-supporting machine and a method for using the same. A part of the power for lifting a transplanting rod is converted into the gravitational potential energy for lifting the transplanting rod and a transplanting needle, and another part is distributed to a power connecting rod through a power distribution mechanism and becomes the kinetic energy for driving the power connecting rod to rise. The latter part of the power is used as the power source for the left-right reciprocating movement of the seedling tray. When the power connecting rod is rising, the power connecting rod transmits the power to the power input joint. If the direction rod is in the left movement gear, the power converter controls the sprocket shaft to rotate, driving the sprocket to rotate. The sprocket transmits the power to the chain, and the chain drives the seedling tray to move linearly to the left. If the direction bar is in the right movement gear, when the power converter controls the sprocket shaft to rotate, the sprocket is driven to rotate, and the sprocket transmits power to the chain, and the chain drives the seedling tray to move in a straight line to the right. Therefore, the power distribution mechanism and the left and right reciprocating mechanism of the seedling tray disclosed in the present invention can decompose the vertical interlacing kinetic energy into the vertical kinetic energy and the left and right reciprocating kinetic energy, which can not only complete the activities of transplanting or similar transplanting (such as sowing), but also automatically control the left and right reciprocating of the seedling tray, etc., and can be widely used in various production activities such as sowing, transplanting, fertilizing, etc. that have both vertical up and down activities and left and right reciprocating movements. In addition, the portable rice seedling supplementing machine disclosed in the present invention has the advantages of small size, light weight and suitability for hand-held operations. It uses a manual transplanting rod as power for mechanical seedling supplementation, can supplement seedlings one by one, and can supplement seedlings at any place in the rice pond without manual bending over to supplement seedlings, which reduces labor intensity and improves seedling supplementation efficiency, which is specifically manifested in:

[0026] (1) The portable rice seedling transplanter disclosed in the present invention is small in size. Specifically, the stretched height of the transplanting handle is 100 cm, and the transplanting height is 75 cm, which is ergonomic and ensures that the transplanting does not require bending over; the height of the fixed handle (15) from the ground is 45 cm, which is convenient for walking and changing hands.

[0027] (2) The portable rice seedling transplanter disclosed in the present invention is light in weight as follows: a 0.7 mm thick thin steel plate is used as the bottom plate, a 0.5 to 0.7 mm thick thin-walled stainless steel square tube is used as the support rod and connecting square tube, and a 10*2 mm flat iron bar is used as the seedling tray support, thereby achieving the goal of the whole machine weighing about three kilograms.

[0028] (3) The portable rice seedling-supporting machine disclosed in the present invention has a portable design for the whole machine, and is respectively provided with a fixed handle and a transplanting handle. The fixed handle is fixed to the sleeve of the main support, and the transplanting handle is fixed to the top of the transplanting rod. The stretching height of the transplanting handle is 100 cm, and the transplanting height is 75 cm, which is convenient for transplanting operations.

[0029] (4) The portable rice seedling-supporting machine disclosed in the present invention has a vertical rice seedling-supporting mechanism which further comprises a rice seedling-ejecting mechanism. The bottom plate of the rice seedling tray slide and the rice seedling tray slide are both provided with rice seedling-supporting holes for the rice seedling-supporting needle to pass through downward. The tip of the rice seedling-supporting needle faces the rice seedling-supporting hole and the rice seedling-supporting opening, so as to ensure that the rice seedling-supporting needle can intercept the rice seedling from the rice seedling block when it descends and smoothly pass the clamped rice seedling through the rice seedling-supporting opening and insert it into the rice seedling field. A notch is left in the rice seedling-supporting hole, and an elastic block is provided at the notch of the rice seedling-supporting hole. An elastic block support is provided on the support rod or the bottom plate, so as to prevent the rice seedling-supporting needle from scratching and lifting the rice seedling upward when the rice seedling-supporting rod rises and passes through the rice seedling-supporting hole.

[0030] (5) The portable rice seedling-replacing machine disclosed in the present invention has a power converter modified from a two-way ratchet wrench. Regardless of the number of gears in the two-way ratchet wrench, the gear spacing inside the two-way ratchet wrench is the same. Therefore, the distance between the leftmost end of the seedling tray and the origin, and the distance between the rightmost end and the origin are equidistant through the seedling tray left-right reciprocating mechanism. The equidistant distance can be adjusted by modifying the gear spacing inside the two-way ratchet wrench. The seedling tray left-right reciprocating mechanism automatically controls the seedling tray to reciprocate left-right, greatly improving the speed of seedling-replacing and greatly improving labor productivity.

[0083] The rice planting needle 32 is inserted at the bottom end of the rice planting rod 31 and a gap is left for inserting the rice planting needle spring 322. The connection between the rice planting needle 32 and the rice planting rod 31 is provided with a rice planting needle spring 322. Fig. 9 As shown, the tip of the transplanting needle 32 faces the transplanting needle hole 320 and the transplanting port 10 to ensure that the transplanting needle 32 can intercept the seedlings from the seedling block when it descends and smoothly pass the clamped seedlings through the transplanting port 10 and insert them into the rice field.

[0084] In order to achieve the purpose of "when the transplanting rod 31 is pressed down to the lowest point, the seedlings clamped on the transplanting needle 32 are just inserted into the rice field", it is necessary to control the depth of the seedlings in the rice field. In order to control the depth of the seedlings in the rice field, an elastic block 324 is provided on the transplanting needle 32. A specific implementation is: an elastic block support 323 is provided on the bottom of the support rod 12 and on the side facing the transplanting port 10, such as Fig. 9 As shown; another specific implementation is: an elastic block support 323 is provided on the bottom plate 11, specifically, an elastic block support mounting hole is installed on the bottom plate 11, the bottom surface of the support rod 12, the elastic block support mounting hole and the transplanting port 10 are located on the same straight line from back to front, the transplanting port 10 is located on the extension line of the bottom center of the support rod 12 and the center of the elastic block support mounting hole, and the elastic block support 323 is installed on the elastic block support mounting hole. When the seedlings clamped by the transplanting needle 32 pass through the transplanting port 10 and are inserted into the rice field to reach the target depth, the elastic block 324 is blocked by the elastic block support 323 to prevent the seedlings from being inserted too deep, so as to control the depth of the transplanting needle 32 in the rice field.

[0085] In order to further increase the transplanting depth, a limiting block 311 is provided on the transplanting rod 31 above the sleeve 13 .

[0086] When the transplanting rod 31 is pressed down until the limit block 311 reaches the sleeve 13 , the limit block 311 can limit the further descent of the transplanting rod 31 to control the pressing depth of the transplanting rod 31 .

[0087] In order to facilitate downward pressing, a transplanting handle 312 is fixed to the top of the transplanting rod 31. The stretching height of the transplanting handle 312 is 100 cm, and the transplanting height is 75 cm, which is ergonomic and ensures that there is no need to bend over when transplanting rice.

[0088] It should be pointed out that, since the seedlings in the seedling block are constantly consumed during the transplanting process, it is necessary to move the seedling tray 21 to adjust the position of the seedling block. In order to reduce the manpower consumption of adjusting the position of the seedling block and improve the automation capability, a specific implementation method is that the portable rice seedling supplementing machine needs to move the seedling tray 21 to the left or right after the transplanting needle 32 intercepts the seedlings from the seedling block, and replenish the seedlings in the transplanting needle hole 320, so that when the transplanting rod 31 is pressed down and passes through the transplanting needle hole 320 at the edge of the seedling tray 21, the transplanting needle 32 can intercept the seedlings from the seedling block. Therefore, the portable rice seedling supplementing machine also needs to include a power distribution mechanism 4 and a seedling tray left and right reciprocating mechanism 5.

[0089] refer to Fig.10 and Fig.11 The power distribution mechanism 4 includes an active contact 41, a power connecting shaft 42, a power slide 43 and a power connecting rod 44.

[0090] The power slide 43 is fixed on the connecting square tube 14 and is parallel to the support rod 12 and the transplanting rod 31. A slide groove 430 is provided on the power slide 43, and the power connecting shaft 42 is provided in the slide groove 430 of the power slide 43.

[0091] The end of the power connection shaft 42 is provided with a driven contact 420. Specifically, the end of the power connection shaft 42 is fixedly connected to a fixed block to form the driven contact 420.

[0092] An active contact 41 is provided at the bottom of the transplanting rod 31. Specifically, a fixed block is fixed at the bottom of the transplanting rod 31 to form the active contact 41, and the active contact 41 is located above the connection between the transplanting needle 32 and the transplanting rod 31, that is, above the transplanting needle spring 322.

[0093] The top end of the power connecting rod 44 is fixedly connected to the power connecting shaft 42 .

[0094] When the transplanting rod 31 is lifted, the transplanting needle 32 rises and passes through the transplanting opening 10. At the same time, the active contact 41 of the transplanting rod 31 contacts the driven contact 420 of the power connecting shaft 42 and pushes the driven contact 420 to rise, driving the power connecting shaft 42 to rise, and then driving the power connecting rod 44 to rise.

[0095] Therefore, part of the power for lifting the transplanting rod 31 is converted into the gravitational potential energy of the transplanting rod 31 and the transplanting needle 32, and the other part is distributed to the power connecting rod 44 through the power distribution mechanism 4 and becomes the kinetic energy that drives the power connecting rod 44 to rise. The latter part of the power is used as the power source for the left and right reciprocating motion of the seedling tray.

[0096] refer to Figures 12 to 14 The seedling tray left and right reciprocating mechanism 5 receives the downward pressing or upward lifting power from the power connecting rod 44 and transmits the power to the seedling tray 21, so that the seedling tray 21 performs left and right reciprocating motion. The seedling tray left and right reciprocating mechanism 5 includes a power converter 51, a sprocket shaft 52, a sprocket 53, a chain 54 and a chain bracket 55 in the order of power transmission.

[0097] refer to Fig.15 The power converter 51 includes a direction rod 511, a power input connector 512 and a sprocket shaft hole 513, and the bottom end of the power connecting rod 44 is fixedly connected to the power input connector 512 of the power converter 51 by bolts;

[0098] One end of the sprocket shaft 52 is inserted into the sprocket shaft hole 513 of the power converter 51, and the other end of the sprocket shaft 52 is provided with a sprocket 53;

[0099] The chain 54 is fixed to the back side of the seedling tray 21 through a chain bracket 55 , the sprocket shaft 52 is arranged below the chain 54 and the sprocket 53 is meshed with the chain 54 .

[0100] The direction rod 511 has a leftward movement gear and a rightward movement gear, and the seedling tray left and right reciprocating mechanism 5 also includes a leftward return control rod 56 and a rightward return control rod 57. Fig.16 As shown, the right return control rod 57 and the left return control rod 56 are respectively fixed on the seedling tray bracket 23, and the bottom ends of the right return control rod 57 and the left return control rod 56 are respectively arranged to just touch the direction rod 511 and enable it to shift gears when the seedling tray 21 moves to the rightmost end and moves to the leftmost end.

[0101] When the direction rod 511 is in the leftward or rightward movement gear, the power converter 51 controls the sprocket shaft 52 and the sprocket 53 to rotate clockwise or counterclockwise respectively, so as to cause the chain 54 and the seedling tray 21 to move back and forth left and right on the seedling tray support 23 .

[0102] Specifically, a sprocket shaft fixing sleeve 16 for fixing the sprocket shaft 52 is provided on the support rod 12, one end of which the power converter 51 is installed is fixed to the support rod 12 of the main bracket 1 through the sprocket shaft fixing sleeve 16, and one end of which the sprocket 53 is installed is fixed to the seedling tray bracket 23 of the seedling tray mechanism 2 through the triangular fixing frame 531. Fig.10 shown.

[0103] The power converter 51 is modified from a two-way ratchet wrench, which is a prior art and generally has 24 teeth or 72 teeth. Fig.17The bidirectional ratchet wrench includes a ratchet seat 500 and a handle 502. The ratchet seat 500 is provided with a quick release button 503 and a forward and reverse paddle 501. The quick release button 503 of the ratchet seat 500 is removed to form a sprocket shaft hole 513. A rod is welded on the quick forward and reverse paddle 501 to form a direction rod 511. The handle 502 is pinned off and two mounting holes are opened to form a power input connector 512.

[0104] Specifically, the two-way ratchet wrench can be a ratchet 1 / 4 small flying 24 gear, or a ratchet 1 / 4 small flying 72 gear. For more specific internal structures and connection relationships of the two-way ratchet wrench, reference can be made to the Chinese utility model application "A two-way ratchet wrench" (application number CN201220115555.7), the Chinese utility model application "Steering switching structure of a two-way ratchet wrench" (application number CN200420096294.4), and the Chinese invention application "Ratchet wrench reversing device" (application number CN201410378553.0).

[0105] It should be noted that, since the power converter 51 is modified from a two-way ratchet wrench, no matter the two-way ratchet wrench is a 24-gear or a 72-gear, the gear spacing inside the two-way ratchet wrench is the same, so the distance between the leftmost end and the origin of the left and right reciprocating motion of the seedling tray 21 realized by the seedling tray left and right reciprocating mechanism 5, and the distance between the rightmost end and the origin are equidistant, and by modifying the gear spacing inside the two-way ratchet wrench, this equidistant distance can be adjusted. The seedling tray left and right reciprocating mechanism 5 automatically controls the seedling tray to go back and forth, greatly improving the speed of seedling filling and greatly improving labor productivity.

[0106] During the rising process of the power connecting rod 44, the power connecting rod 44 transmits power to the power input connector 512 of the power converter 51. If the direction rod 511 is in the left movement gear, the power converter 51 controls the sprocket shaft 52 to rotate, driving the sprocket 53 to rotate, and the sprocket 53 transmits power to the chain 54. The chain 54 moves the seedling tray 21 in a straight line to the left; if the direction rod 511 is in the right movement gear, the power converter 51 controls the sprocket shaft 52 to rotate, driving the sprocket 53 to rotate, and the sprocket 53 transmits power to the chain 54. The chain 54 moves the seedling tray 21 in a straight line to the right.

[0107] When the chain 54 moves rightward with the seedling tray 21 to the rightmost end, the left-returning control rod 56 touches the direction rod 511, causing the direction rod 511 to change to the leftward movement gear; conversely, when the chain 54 moves leftward with the seedling tray 21 to the leftmost end, the right-returning control rod 57 touches the direction rod 511, causing the direction rod 511 to change to the rightward movement gear.

[0108] Since the power connection shaft 42 can not only move up and down along the slide groove 430 in the power slideway 43, but also rotate around the power connection shaft 42 as the center, it is necessary to control the rotation amplitude of the power connection shaft 42. For this purpose, the power distribution mechanism 4 also includes a power slider 45.

[0109] refer to Fig.18 The power slider 45 includes a slider connecting block 451, a slider rotating block 452 and a slider adjusting rod 453.

[0110] The slider rotating block 452 is formed by twisting a steel bar, and its lower part is provided with an arc hook. The shape of the entire slider rotating block is S-shaped.

[0111] The slider rotating block 452 is disposed at the bottom end of the slider connecting block 451, and the slider adjusting rod 453 is vertically fixed to the middle of the slider connecting block 451;

[0112] refer to Fig.19 The upper end and the lower end of the power slide 43 are respectively fixed with an upper limit rod 431 and a lower limit rod 432.

[0113] The top end of the slider connection block 451 is fixedly connected to the power connection shaft 42 , and the slider adjustment rod 453 is located between the upper limit rod 431 and the lower limit rod 432 of the power slideway 43 .

[0114] When the transplanting rod 31 is lifted, the active contact 41 at the bottom of the transplanting rod 31 first enters the arc hook of the slider rotating block 452, and while driving the power connecting shaft 42 to move upward along the slide groove 430 in the power slideway 43, it can also cause the power slide block 45 to rotate. Since the slide adjustment rod 453 of the power slide block 45 is restricted between the upper limit rod 431 and the lower limit rod 432 of the power slideway 43, until the slide adjustment rod 453 of the power slide block 45 is blocked by the upper limit rod 431, at this time, the power slide block 45 and the power connecting shaft 42 connected thereto rise to the highest point and then stop rising; when the transplanting rod 31 is pressed down, the active contact 41 of the transplanting rod 31 is out of contact with the driven contact 420 of the power connecting shaft 42, and the power slide block 45 and the power connecting shaft 42 connected thereto slide down under the action of their own gravity until the slide adjustment rod 453 of the power slide block 45 is blocked by the lower limit rod 432, and then they reach the lowest point and stop sliding down.

[0115] Specifically, a shaft hole is provided at the top of the slider connection block 451 , and the power connection shaft 42 passes through the shaft hole of the slider connection block 451 and is fixed.

[0116] The seedling tray 21 will have a seedling block that is suitable for the size of the seedling tray 21, and a matching seedling device has been developed for this purpose, such as Fig. 20Therefore, the portable rice seedling supplementing machine also includes a seedling supplementing device 5, and before supplementing the seedlings, the seedlings are supplemented by the seedling supplementing device 5. The seedling blocks supplemented by the seedling supplementing device are standard and fast, which is convenient for the seedling tray 21 to be loaded with seedlings, and the supplementing speed is accelerated again.

[0117] Example 2

[0118] Embodiment 2 provides a method for using a portable rice seedling-replenishing machine, using the portable rice seedling-replenishing machine provided in Embodiment 1, the method comprising the following steps:

[0119] Step S1: Gd seedlings and seedling loading:

[0120] After using the seedling clamp to clamp the seedling block, use a fruit knife to cut the seedlings;

[0121] The power connecting rod 44 is squeezed by hand to move up and down, and the seedling tray 21 is moved to the leftmost end or the rightmost end, and then the seedling block is installed on the seedling tray 21, and the seedling clamp 25 of the seedling block pushing rod 24 is pulled to the front end of the seedling tray 21, and the hook 251 of the seedling clamp 25 is hooked on the front end of the seedling tray 21. After the hook 251 is pulled up, the two tension springs 26 pull the seedling block pushing rod 24 back at the same time until the seedling clamp 25 is pulled back to the initial position by the seedling block pushing rod 24, and the seedling clamp hook 252 just clamps the seedling block on the seedling tray 21, and the seedling loading is completed;

[0122] Step S2: carrying the rice transplanting pole to the place where the rice seedlings are missing to complete the one-hole transplanting, specifically including the following steps:

[0123] The transplanting rod 31 is pressed down, and the transplanting needle 32 intercepts the seedlings from the seedling block and inserts the clamped seedlings through the transplanting opening 10 into the rice field;

[0124] The transplanting rod 31 is lifted up, and the transplanting needle 32 rises and passes through the transplanting opening 10. At the same time, the active contact 41 of the transplanting rod 31 contacts the driven contact 420 of the power connecting shaft 42 and pushes the driven contact 420 to rise, thereby driving the power connecting shaft 42 and the power connecting rod 44 to rise; during the rising process of the power connecting rod 44, the power connecting rod 44 transmits power to the power input connector 512. If the direction rod 511 is in the left movement gear, the power converter 51 controls the sprocket shaft 52 to rotate, driving the sprocket 53 to rotate, and the sprocket 53 transmits power to the chain 54, and the chain 54 moves the seedling tray 21 to the left in a straight line; if the direction rod 511 is in the right movement gear, the power converter 51 controls the sprocket shaft 52 to rotate, driving the sprocket 53 to rotate, and the sprocket 53 transmits power to the chain 54, and the chain 54 moves the seedling tray 21 to the right in a straight line;

[0125] Step S3: Repeat step S2. When the chain 54 moves the seedling tray 21 to the right to the rightmost end, the left control rod 56 touches the direction rod 511, so that the direction rod 511 changes to the leftward movement gear. On the contrary, when the chain 54 moves the seedling tray 21 to the left to the leftmost end, the right control rod 57 touches the direction rod 511, so that the direction rod 511 changes to the rightward movement gear. After the seedlings in the seedling tray 21 are planted, step S1 is repeated to plant and load the seedlings, and step S2 is repeated to continue to fill the seedlings until all the filling is completed.

[0126] Finally, with regard to the portable rice seedling transplanter disclosed in the present invention, the following matters needing attention during use are noted:

[0127] (1) When transplanting seedlings, the transplanting pole should be raised to the top and inserted to the bottom.

[0128] (2) It is normal for the seedling tray to be empty once every time it moves to the left.

[0129] (3) During the rest period of the seedling transplanting process, the transplanting needles and transplanting rod bearings should be rinsed with water.

[0130] (4) When placing and transporting the seedling tray, it should be on the left and it is strictly forbidden to throw, drop or squeeze it.

[0131] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.

After the hook (251) is pulled up, two tension springs (26) pull the seedling block pushing rod (24) back at the same time until the seedling holder (25) is pulled back to the initial position by the seedling block pushing rod (24), and the seedling holder hook (252) just clamps the seedling block on the seedling tray (21), and the seedling installation is completed; Step S2: carrying the rice transplanting pole to the place where the rice seedlings are missing to complete the one-hole transplanting, specifically including the following steps: The rice planting rod (31) is pressed down, and the rice planting needle (32) cuts the rice seedlings from the rice seedling block and inserts the clamped rice seedlings through the rice planting opening (10) into the rice seedling field; The rice planting rod (31) is lifted up, and the rice planting needle (32) rises and passes through the rice planting opening (10). At the same time, the active contact (41) of the rice planting rod (31) contacts the driven contact (420) of the power connecting shaft (42) and pushes the driven contact (420) to rise, thereby driving the power connecting shaft (42) and the power connecting rod (44) to rise. During the rising process of the power connecting rod (44), the power connecting rod (44) transmits power to the power input connector (512). If the direction rod (511) is in the direction When the left movement gear is in the gear, the power converter (51) controls the sprocket shaft (52) to rotate, driving the sprocket (53) to rotate, the sprocket (53) transmits power to the chain (54), and the chain (54) moves the seedling tray (21) to the left in a straight line; when the direction rod (511) is in the gear for right movement, the power converter (51) controls the sprocket shaft (52) to rotate, driving the sprocket (53) to rotate, the sprocket (53) transmits power to the chain (54), and the chain (54) moves the seedling tray (21) to the right in a straight line; Step S3: Repeat step S2. When the chain (54) moves the seedling tray (21) to the right to the rightmost end, the left return control rod (56) touches the direction rod (511), so that the direction rod (511) changes to the leftward movement gear. On the contrary, when the chain (54) moves the seedling tray (21) to the left to the leftmost end, the right return control rod (57) touches the direction rod (511), so that the direction rod (511) changes to the rightward movement gear. After the seedlings in the seedling tray (21) are planted, step S1 is repeated to carry out seedling planting and seedling loading, and step S2 is repeated to continue seedling filling until all seedling filling is completed.
