Description

Technical Field

[0001] The present invention relates to the technical field of crop seedling transplanting equipment, and particularly to a transplanter. Background Art

[0002] In agricultural machinery, the most common way to transplant crop seedlings is the duckbill transplanting method. Refer to the application number: 201210379857.X, which discloses a "seedling transplanter". This solution uses a cam to push a reciprocating swing rod and a balance rod to complete the forward and backward and up and down movements, and uses a duckbill type hole punching and seedling placing device to complete the hole punching and seedling placing process at one time. However, with the continuous development of the crop well-cellar cultivation mode and off-season planting technology, since the duckbill type hole punching and seedling placing device needs to open and close frequently in the soil to place seedlings, not only is it easy to tear the mulch film on the soil ridge when opening and emerging from the soil, but also when the soil moisture content is relatively high, the soil and crop seedlings adhered to the duckbill will be carried away from the ridge surface, seriously reducing the transplanting quality, and at the same time, it cannot meet the usage requirements of the current well-cellar type transplanting. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a transplanter that can avoid tearing the mulch film on the soil ridge while ensuring effective hole punching.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: a transplanter, including a frame, a translation component, and a hole punching component; the translation component includes a sector sprocket, a first chain, a moving frame, and a first tension spring;

[0005] The sector sprocket is rotatably arranged on the frame and is in transmission connection with the power source of the transplanter, and the sector sprocket meshes with the first chain;

[0006] The first chain is horizontally arranged on the moving frame, and the moving frame is slidably arranged on the frame;

[0007] The first tension spring is horizontally arranged, and both ends of the first tension spring are respectively connected to the frame and the moving frame;

[0008] The hole punching component is arranged on the moving frame, the hole punching component includes a reciprocating device and a hole punching cone, the moving end of the reciprocating device moves in the vertical direction, and the hole punching cone is connected to the moving end of the reciprocating device.

[0009] The beneficial effects of the present invention are as follows: A moving frame of a translation component is added to the frame of the transplanter. During the process of the transplanter moving forward along the ridge to punch holes, while the reciprocating device of the hole-punching component drives the hole-punching cone to move vertically downward, the moving frame uses the cooperation of the sector sprocket and the first chain to drive the hole-punching component to move away from the forward direction of the transplanter, so as to offset the forward speed of the hole-punching component on the transplanter. Furthermore, it ensures that a well-cell type deep hole can be obtained after the hole-punching cone penetrates into the ridge, and at the same time, the hole-punching cone will not be dragged by the transplanter to tear the film on the ridge. After the one-way bearing sprocket rotates and separates from the second chain, the mounting frame will reset upward under the elastic force of the second tension spring, and at the same time drive the hole-punching cone to withdraw from the ridge.

[0026] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0027] Please refer to Figure 1 As shown, a transplanter of the present invention includes a frame 1, a translation assembly 2 and a hole punching assembly 3; the translation assembly 2 includes a sector sprocket 21, a first chain 22, a moving frame 23 and a first tension spring 24;

[0028] The sector sprocket 21 is rotatably arranged on the frame 1 and is in transmission connection with the power source of the transplanter, and the sector sprocket 21 meshes with the first chain 22;

[0029] The first chain 22 is horizontally arranged on the moving frame 23, and the moving frame 23 is slidably arranged on the frame 1;

[0030] The first tension spring 24 is horizontally arranged, and both ends of the first tension spring 24 are respectively connected to the frame 1 and the moving frame 23;

[0031] The hole punching assembly 3 is arranged on the moving frame 23, the hole punching assembly 3 includes a reciprocating device 35 and a hole punching cone 36, the moving end of the reciprocating device 35 moves in the vertical direction, and the hole punching cone 36 is connected to the moving end of the reciprocating device 35.

[0032] As can be seen from the above description, the beneficial effects of the present invention are as follows: A moving frame 23 of the translation assembly 2 is added to the frame 1 of the transplanter. During the process of the transplanter moving forward along the ridge to punch holes, while the reciprocating device 35 of the hole punching assembly 3 drives the hole punching cone 36 to move vertically downward, the moving frame 23 utilizes the cooperation of the sector sprocket 21 and the first chain 22 to realize that the moving frame 23 drives the hole punching assembly 3 to move away from the forward direction of the transplanter, so as to offset the forward speed of the hole punching assembly 3 on the transplanter, and further ensure that the hole punching cone 36 can obtain a deep hole after breaking into the ridge, rather than being dragged by the transplanter to become a long strip-shaped hole, resulting in tearing the film on the ridge. After the sector sprocket 21 rotates and separates from the first chain 22, the moving frame 23 will reset under the elastic force of the first tension spring 24, and at the same time the reciprocating device 35 drives the hole punching cone 36 to withdraw from the ridge.

[0033] Please refer to Figure 1 As shown, further, a first roller 231 is provided on the moving frame 23, and the wheel surface of the first roller 231 abuts against the frame 1.

[0034] As can be seen from the above description, by using the first roller 231 in a rolling manner, the contact area between the moving frame 23 and the frame 1 can be reduced, thereby preventing the soil splashed out during the hole punching process of the hole punching assembly 3 from sticking to the frame 1 and affecting the movement of the moving frame 23 on the frame 1.

[0035] Please refer to Figure 2 As shown, further, the hole punching assembly 3 further includes a mounting frame 31, a slide rail 32, a second roller 33 and a mounting plate 34; the mounting frame 31 is provided on the moving frame 23, the slide rail 32 is provided on the mounting frame 31, and the extending direction of the slide rail 32 is the vertical direction. The wheel surface of the second roller 33 abuts against the slide rail 32. The second roller 33 is connected to the mounting plate 34. The movable end of the reciprocating device 35 is connected to the mounting plate 34, and the hole punching cone 36 is connected to the mounting plate 34.

[0036] As can be seen from the above description, by using the second roller 33 in a rolling manner, the contact area with the slide rail 32 can be reduced, so that when the reciprocating device 35 drives the mounting plate 34 to move in the vertical direction, the movement of the mounting plate 34 driving the hole punching cone 36 in the vertical direction will not be affected by the soil sticking to the second roller 33 and the slide rail 32.

[0037] Please refer to Figure 2 As shown, further, the reciprocating device 35 includes a one-way bearing sprocket 351, a rotating shaft 352, a second chain 353, a rope 354 and a second tension spring 355; the one-way bearing sprocket 351 is connected to the rotating shaft 352, the rotating shaft 352 is connected to the moving frame 23, the second chain 353 is provided on the frame 1, the second chain 353 meshes with the one-way bearing sprocket 351, both ends of the rope 354 are respectively connected to the rotating shaft 352 and the second tension spring 355, the rope 354 is connected to the mounting plate 34, and the second tension spring 355 is provided on the mounting frame 31.

[0038] As can be seen from the above description, during the process of the sector sprocket 21 and the first chain 22 cooperating to drive the moving frame 23 to move, since the one-way bearing sprocket 351 is connected to the moving frame 23 through the rotating shaft 352 and the second chain 353 is provided on the frame 1, at this time, the one-way bearing sprocket 351 will roll forward on the second chain 353, so that the rope 354 is wound up by the rotating shaft 352, and then the mounting plate 34 connected to the rope 354 starts to move downward on the slide rail 32, inserting the hole punching cone 36 into the ridge.

[0039] When the one-way bearing sprocket 351 rolls to the end of the second chain 353, the one-way bearing sprocket 351 will separate from the second chain 353 at this time. Under the elastic force of the second tension spring 355, the rotating shaft 352 and the one-way bearing sprocket 351 are reset, and the rope 354 is released. Furthermore, the mounting plate 34 connected to the rope 354 starts to move upward on the slide rail 32, pulling out the hole punching cone 36 from the ridge.

[0040] Please refer to Figure 1 and Figure 3 As shown, further, the above transplanting machine further includes a seedling distribution device 4. The seedling distribution device 4 includes a seedling tray 41, a partition component 42, a seedling distribution funnel 43 and a baffle 44; the seedling tray 41 is rotatably arranged on the transplanting machine, and a plurality of seedling cups 411 are arranged on the seedling tray 41. The partition component 42 is slidably arranged at the discharge end of the seedling tray 41. The sliding direction of the partition component 42 is parallel to the moving direction of the moving frame 23. A through hole 421 is arranged on the partition component 42. The seedling distribution funnel 43 is connected to the moving frame 23; the baffle 44 is arranged on the frame 1;

[0041] When the feed end of the seedling distribution funnel 43 is located below the discharge end of the seedling tray 41, the through hole 421 communicates with the seedling cup 411, and the baffle 44 intercepts at the discharge end of the seedling distribution funnel 43;

[0042] When the feed end of the seedling distribution funnel 43 is far from the discharge end of the seedling tray 41, the partition component 42 intercepts at the lower outlet end of the seedling tray 41, and the discharge end of the seedling distribution funnel 43 is far from the baffle 44.

[0043] As can be seen from the above description, when the moving frame 23 is pulled back to its original position by the first tension spring 24, the feed end of the seedling distribution funnel 43 is located below the discharge end of the seedling tray 41. At this time, the seedlings in the seedling cup 411 at the discharge end of the seedling tray 41 will pass through the through hole 421 of the partition component 42 and fall into the seedling distribution funnel 43, and are intercepted by the baffle 44 at the discharge end of the seedling distribution funnel 43 to prepare for dropping the seedlings when the transplanting machine moves to just above the hole just punched by the hole punching cone 36.

[0044] When the moving frame 23 moves away from the forward direction of the transplanting machine under the cooperation of the sector sprocket 21 and the first chain 22, the feed end of the seedling distribution funnel 43 will be far from the discharge end of the seedling tray 41, so that the seedlings at the discharge end of the seedling distribution funnel 43 can fall out from the discharge end of the seedling distribution funnel 43 and fall into the hole just punched by the hole punching cone 36 of the transplanting machine on the ridge.

[0045] Furthermore, when the hole punching component 3 punches a new hole, the seedling distribution device 4 will distribute a seedling at the previously punched hole.

[0046] Please refer to Figure 3As shown in the figure, further, the partition assembly 42 includes a third tension spring 422, an intercepting plate 423, and a pushing plate 424; both ends of the third tension spring 422 are respectively connected to the frame 1 and the intercepting plate 423. The intercepting plate 423 is located at the discharging end of the lower outlet of the seedling tray 41. The through hole 421 is provided on the intercepting plate 423. The pushing plate 424 is arranged on the end face of the intercepting plate 423 away from the seedling tray 41, and the pushing plate 424 abuts against the outer wall of the seedling distribution funnel 43.

[0047] As can be seen from the above description, when the moving frame 23 drives the seedling distribution funnel 43 to move below the discharging end of the seedling tray 41, since the pushing plate 424 abuts against the outer wall of the seedling distribution funnel 43, during the movement of the seedling distribution funnel 43, it will drive the intercepting plate 423 to move through the pushing plate 424 at the same time, so that the through hole 421 gradually approaches the seedling discharging end of the seedling tray 41 and stretches the third tension spring 422.

[0048] When the moving frame 23 drives the seedling distribution funnel 43 to move away from the discharging end of the seedling tray 41, under the elastic force of the third tension spring 422, the intercepting plate 423 will make the through hole 421 gradually move away from the discharging end of the seedling tray 2, and then block the discharging end of the seedling tray 41.

[0049] Please refer to Figure 1 As shown in the figure, further, the above-mentioned transplanter further includes a water distribution device 5; the water distribution device 5 includes a water tank 51, a control valve 52, and a water distribution chamber 53; the water inlet end of the control valve 52 is connected to the water outlet end of the water tank 51 through a pipeline, the water distribution chamber 53 is connected to the water outlet end of the control valve 52 through a pipeline. The water distribution chamber 53 has a water outlet 531. The water distribution chamber 53 is sleeved on the seedling distribution funnel 43, and the discharging end of the seedling distribution funnel 43 extends out of the water outlet 531 of the water distribution chamber 53, and the diameter of the water outlet 531 is larger than the diameter of the discharging end of the seedling distribution funnel 43.

[0050] As can be seen from the above description, during the seedling distribution process, the water in the water tank 51 enters the water distribution chamber 53 through the control valve 52, and the water in the water distribution chamber 53 forms a ring of water in cooperation with the discharging end of the seedling distribution funnel 43 at the water outlet 531. In this way, after the seedlings fall into the holes, the soil around the seedlings will fill the gap between the holes and the seedlings under the flushing of the ring of water to ensure the survival rate of the seedlings.

[0051] Please refer to Figure 4As shown, further, the control valve 52 includes a valve body 521 and a throttle block 522 slidably disposed in the inner cavity of the valve body 521. The valve body 521 includes a first port 5211, a second port 5212, and an avoidance chamber 5213 that communicate with each other. The first port 5211 is connected to the water tank 51 through a pipeline, the second port 5212 is connected to the water distribution chamber 53 through a pipeline, and the avoidance chamber 5213 has a space for the throttle block 522 to enter.

[0052] When the discharge end of the seeding funnel 43 is away from the baffle 44, the throttle block 522 intercepts at the connection between the first port 5211 and the second port 5212.

[0053] When the baffle 44 intercepts at the discharge end of the seeding funnel 43, the throttle block 522 enters the avoidance chamber 5213, and the first port 5211 and the second port 5212 are connected.

[0054] As can be seen from the above description, the movement of the throttle block 522 in the valve body 521 is utilized to control the connection between the first port 5211 and the second port 5212, so as to control the water output of the water distribution chamber 53.

[0055] Please refer to Figure 1 and Figure 4 As shown, further, the control valve 52 further includes a linkage rod 523. The linkage rod 523 penetrates the valve body 521, and the linkage rod 523 is slidably connected to the valve body 521 relatively, and the throttle block 522 is disposed on the linkage rod 523.

[0056] There are a first abutting member 6 and a second abutting member 7 opposite to each other on the frame 1.

[0057] When one end of the linkage rod 523 abuts against the first abutting member 6, the throttle block 522 intercepts at the connection between the first port 5211 and the second port 5212.

[0058] When the other end of the linkage rod 523 abuts against the second abutting member 7, the throttle block 522 enters the avoidance chamber 5213.

[0059] As can be seen from the above description, the abutment of the first abutting member 6 and the second abutting member 7 with the corresponding ends of the linkage rod 523 is utilized to control the movement of the throttle block 522 in the valve body 521.

[0060] Please refer to Figure 1 As shown, further, universal wheels 11 are provided at the front end of the frame 1, and a guide plate 111 is provided on the universal wheels 11.

[0061] From the above description, it can be seen that since the soil ridge is not a straight line, when the transplanter moves along the soil ridge, the guide plate 111 is used to abut against the edge of the soil ridge, so that the universal wheel 11 compensates and corrects itself, so that the transplanter can always move along the soil ridge, and then the acupuncture component 3 can always acupuncture along the soil ridge.

[0062] An application scenario of a transplanter of the present invention: when it is necessary to drill holes on a soil ridge, a movable frame 23 of a translation assembly 2 is added to the frame 1 of the transplanter. During the process of the transplanter moving forward along the soil ridge to drill holes, the reciprocating device 35 of the drilling assembly 3 drives the drilling cone 36 to move vertically downward. At the same time, the movable frame 23 utilizes the cooperation between the fan-shaped sprocket 21 and the first chain 22 to realize that the movable frame 23 drives the drilling assembly 3 to move away from the forward direction of the transplanter, thereby offsetting the forward speed of the drilling assembly 3 on the transplanter, and further ensuring that the drilling cone 36 can obtain a deep hole after breaking into the soil ridge, rather than being dragged by the transplanter and becoming a long strip-shaped hole, and tearing the film on the soil ridge. When the sector sprocket 21 drives the first chain 22 to move the movable frame 23 to a position of about 3 / 4 of the total moving distance, the one-way bearing sprocket is separated from the second chain, and the mounting frame is quickly reset upward under the elastic force of the second tension spring and drives the acupuncture cone to withdraw from the soil ridge and return to its position. After that, the sector sprocket 21 is separated from the first chain 22, and the movable frame 23 returns to its original position under the tension of the first tension spring 24.

[0063] Example 1

[0064] A transplanter, see Figure 1 and Figure 2 As shown, it includes a frame 1, a translation component 2 and a puncture component 3; the translation component 2 includes a fan-shaped sprocket 21, a first chain 22, a mobile frame 23 and a first tension spring 24; the fan-shaped sprocket 21 is rotatably set on the frame 1 and is transmission-connected to the power source of the transplanter, and the fan-shaped sprocket 21 is meshed with the first chain 22; the first chain 22 is horizontally set on the mobile frame 23, and the mobile frame 23 is slidably set on the frame 1; the first tension spring 24 is horizontally set, and the two ends of the first tension spring 24 are respectively connected to the frame 1 and the mobile frame 23; the puncture component 3 is set on the mobile frame 23, and the puncture component 3 includes a reciprocating device 35 and a puncture cone 36, the movable end of the reciprocating device 35 moves in the vertical direction, and the puncture cone 36 is connected to the movable end of the reciprocating device 35. The mobile frame 23 is provided with a first roller 231, and the wheel surface of the first roller 231 abuts against the frame 1.

[0065] Please refer to Figure 2As shown in the figure, the hole punching assembly 3 further includes a mounting frame 31, a slide rail 32, a second roller 33 and a mounting plate 34; the mounting frame 31 is arranged on the moving frame 23, the slide rail 32 is arranged on the mounting frame 31, and the extending direction of the slide rail 32 is the vertical direction. The wheel surface of the second roller 33 abuts against the slide rail 32. The second roller 33 is connected to the mounting plate 34. The movable end of the reciprocating device 35 is connected to the mounting plate 34, and the hole punching cone 36 is connected to the mounting plate 34. The reciprocating device 35 includes a one-way bearing sprocket 351, a rotating shaft 352, a second chain 353, a rope 354 and a second tension spring 355; the one-way bearing sprocket 351 is connected to the rotating shaft 352, the rotating shaft 352 is connected to the moving frame 23, the second chain 353 is arranged on the machine frame 1, the second chain 353 meshes with the one-way bearing sprocket 351, both ends of the rope 354 are respectively connected to the rotating shaft 352 and the second tension spring 355, the rope 354 is connected to the mounting plate 34, and the second tension spring 355 is arranged on the mounting frame 31.

[0066] Working principle: The power source of the transplanter drives the sector sprocket 21 to rotate. The moving frame 23 uses the cooperation of the sector sprocket 21 and the first chain 22 to realize the movement of the moving frame 23 driving the hole punching assembly 3 to move away from the forward direction of the transplanter, so as to offset the forward speed of the hole punching assembly 3 on the transplanter, and further ensure that the hole punching cone 36 can obtain a well-cell type deep hole after breaking into the soil ridge, rather than tearing the mulch on the soil ridge by being towed by the transplanter. When the sector sprocket 21 drives the first chain 22 to move the moving frame 23 to about 3 / 4 of the total moving distance, the one-way bearing sprocket 351 is separated from the second chain 353. The mounting frame 34 quickly resets upward under the elastic force of the second tension spring 355 and drives the hole punching cone 36 to withdraw from the soil ridge. After the hole punching cone 36 is reset, the sector sprocket 21 is separated from the first chain 22, and the moving frame 23 returns to its original position under the pulling force of the first tension spring 24.

[0067] Embodiment 2

[0068] In this embodiment, on the basis of Embodiment 1, it is further defined that the transplanter further includes a seedling distribution device:

[0069] Please refer to Figure 1 and Figure 3As shown in the figure, the seedling placing device 4 includes a seedling tray 41, a partition component 42, a seedling placing funnel 43 and a baffle 44; the seedling tray 41 is rotatably arranged on the transplanter, and a plurality of seedling cups 411 are arranged on the seedling tray 41. The partition component 42 is slidably arranged at the discharge end of the seedling tray 41, and the sliding direction of the partition component 42 is parallel to the moving direction of the moving frame 23. A through hole 421 is arranged on the partition component 42, and the seedling placing funnel 43 is connected to the moving frame 23; the baffle 44 is arranged on the frame 1; when the feeding end of the seedling placing funnel 43 is located below the discharge end of the seedling tray 41, the through hole 421 is communicated with the seedling cup 411, and the baffle 44 intercepts at the discharge end of the seedling placing funnel 43; when the feeding end of the seedling placing funnel 43 is far away from the discharge end of the seedling tray 41, the partition component 42 intercepts at the discharge end of the seedling tray 41, and the discharge end of the seedling placing funnel 43 is far away from the baffle 44. The partition component 42 includes a third tension spring 422, an intercepting plate 423 and a pushing plate 424; both ends of the third tension spring 422 are respectively connected to the frame 1 and the intercepting plate 423. The intercepting plate 423 is located at the discharge end of the seedling tray 41, the through hole 421 is arranged on the intercepting plate 423, the pushing plate 424 is arranged on the end face of the intercepting plate 423 away from the seedling tray 41, and the pushing plate 424 abuts against the outer wall of the seedling placing funnel 43.

[0070] Among them, the seedling cup 411 can be a cylindrical hole; it can also be a hole with a gradually increasing diameter in the direction of the seedling placing funnel 43. The seedling cup 411 with such a shape can ensure that the crop seedlings smoothly fall into the seedling placing funnel 43.

[0071] Working principle: After the moving frame 23 is pulled back to its original position by the first tension spring 24, since the pushing plate 424 abuts against the outer wall of the seedling placing funnel 43, during the process of the seedling placing funnel 43 moving to below the discharge end of the seedling tray 41, it will drive the intercepting plate 423 to move through the pushing plate 424 at the same time, so that the through hole 421 gradually approaches the discharge end of the seedling tray 41 and stretches the third tension spring 422. Thus, the seedlings in the seedling cup 411 at the discharge end of the seedling tray 41 will pass through the through hole 421 and fall into the seedling placing funnel 43, and are intercepted by the baffle 44 at the discharge end of the seedling placing funnel 43 to prepare for the transplanter to move to above the hole just punched by the hole punching cone 36 and release the seedlings.

[0072] When the moving frame 23 moves away from the forward direction of the transplanter under the cooperation of the sector sprocket 21 and the first chain 22, the feeding end of the seedling distribution funnel 43 will move away from the discharging end of the seedling tray 41. Under the elastic force of the third tension spring 422, the intercepting plate 423 will gradually move the through hole 421 away from the discharging end of the seedling tray 2, thereby preventing the rotation of the seedling tray 41 from turning another seedling cup 411 filled with seedlings to the discharging end of the seedling tray 41, so that another seedling falls into the seedling distribution funnel 43 at a non-specified seedling dropping time. After the discharging end of the seedling distribution funnel 43 is separated from the baffle 44, the seedling located at the discharging end of the seedling distribution funnel 43 can fall out from the discharging end of the seedling distribution funnel 43 and fall into the hole just punched by the hole punching cone 36 of the transplanter on the ridge. Thus, while the hole punching assembly 3 punches a new hole, the seedling distribution device 4 will distribute a seedling at the previously punched hole.

[0073] Embodiment III

[0074] In this embodiment, on the basis of Embodiment II, it is further defined that the transplanter further includes a water distribution device:

[0075] Please refer to Figure 1 and Figure 4 As shown, the water distribution device 5 includes a water tank 51, a control valve 52 and a water distribution chamber 53; the water inlet end of the control valve 52 is connected to the water outlet end of the water tank 51 through a pipeline, the water distribution chamber 53 is connected to the water outlet end of the control valve 52 through a pipeline, the water distribution chamber 53 has a water outlet 531, the water distribution chamber 53 is sleeved on the seedling distribution funnel 43, and the discharging end of the seedling distribution funnel 43 extends out of the water outlet 531 of the water distribution chamber 53, and the diameter of the water outlet 531 is larger than the diameter of the discharging end of the seedling distribution funnel 43.

[0076] Among them, the water outlet end of the water outlet 531 is a pipe body with a gradually decreasing diameter towards the discharging end of the seedling distribution funnel. Thereby, the water pressure and flow rate of the water flowing out from the water outlet 531 can be increased, and thus it is ensured that the flowing water is in a circular shape.

[0077] A flow valve is arranged at the water outlet end of the water tank 51 to control the flow rate of the water flowing out of the water tank 51.

[0078] Please refer to Figure 4As shown, the control valve 52 includes a valve body 521 and a throttling block 522 slidably disposed in the inner cavity of the valve body 521. The valve body 521 includes a first port 5211, a second port 5212 and an avoidance chamber 5213 that are interconnected. The first port 5211 is connected to the water tank 51 through a pipeline, the second port 5212 is connected to the water distribution chamber 53 through a pipeline, and the avoidance chamber 5213 has a space for the throttling block 522 to enter. When the discharge end of the seedling sowing funnel 43 is far from the baffle 44, the throttling block 522 intercepts at the connection between the first port 5211 and the second port 5212. When the baffle 44 intercepts at the discharge end of the seedling sowing funnel 43, the throttling block 522 enters the avoidance chamber 5213, and the first port 5211 and the second port 5212 are connected. The control valve 52 further includes a linkage rod 523 that penetrates the valve body 521 and is slidably connected to the valve body 521 relative to the valve body 521. The throttling block 522 is disposed on the linkage rod 523. There are a first abutting member 6 and a second abutting member 7 opposite to each other on the frame 1. When one end of the linkage rod 523 abuts against the first abutting member 6, the throttling block 522 intercepts at the connection between the first port 5211 and the second port 5212. When the other end of the linkage rod 523 abuts against the second abutting member 7, the throttling block 522 enters the avoidance chamber 5213.

[0079] Working principle: While the seedlings fall into the discharge end of the seedling sowing funnel 43 and are intercepted by the baffle 44, the linkage rod 523 of the water distribution device 5 abuts against the second abutting member 7, causing the linkage rod 523 to move, that is, the throttling block 522 enters the avoidance chamber 5213 of the valve body 521, connecting the first port 5211 and the second port 5212, so that the water in the water tank 51 can flow into the water distribution chamber 53.

[0080] After a certain amount of water flows into the water distribution chamber 53, the moving frame 23 drives the seedling sowing funnel 43 away from the baffle 44, causing the linkage rod 523 to start moving towards the first abutting member 6. After the linkage rod 523 abuts against the first abutting member 6, the linkage rod 523 moves, that is, the throttling block 522 intercepts at the connection between the first port 5211 and the second port 5212, preventing water from flowing into the water distribution chamber 53. At the same time, the water in the water distribution chamber 53 and the seedlings located at the discharge end of the seedling sowing funnel 43 will fall towards the holes punched on the ridge together. Since the discharge end of the seedling sowing funnel 43 extends out of the water outlet 531 and the diameter of the water outlet 531 is larger than the diameter of the discharge end of the seedling sowing funnel 43, the water flowing out of the water outlet 531 is in a ring shape. In this way, after the seedlings fall into the holes, the soil around the seedlings will fill the gap between the holes and the seedlings under the flushing of the annular water to ensure the survival rate of the seedlings.

[0081] Embodiment 4

[0082] On the basis of the first embodiment, this embodiment further defines the structure of the frame:

[0083] Please refer to Figure 1 As shown, a universal wheel 11 is provided at the front end of the frame 1, and a guide plate 111 is provided on the universal wheel 11.

[0084] Working principle: Since the ridge is not a straight line, during the process of the transplanter moving along the ridge, the guide plate 111 is used to abut against the edge of the ridge, so that the universal wheel 11 can automatically compensate and correct, enabling the transplanter to always move along the ridge, and further enabling the hole punching assembly 3 to always punch holes along the ridge.

[0085] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the related technical fields, shall be included in the patent protection scope of the present invention by the same token.
