Description

Technical Field

[0001] The invention relates to the field of plug tray seedling raising equipment, and in particular to a seedling supplement planting device. Background Art

[0002] Plug tray seedling cultivation is a modern seedling raising technique that uses lightweight, soilless materials such as peat and vermiculite as a substrate. It uses mechanized, precision seeding, planting one seed per hole, and achieving single-shot seedling success. During batch seedling cultivation, problems such as missed seeds, non-germination, and abnormal leaf growth can occur. Normal seedlings account for approximately 80%-95% of the total seedling population. To ensure consistent seedling growth within the tray and reduce the risk of missed seeds during field transplanting, empty holes and unhealthy seedlings are carefully seeded and removed.

[0003] The most traditional way of replanting seedlings is through manual operation by staff, which consumes a lot of time and energy. Therefore, some mechanical equipment that replaces manual replanting seedlings has appeared on the market. For example, the Chinese invention patent with publication number CN112449818B discloses a double-visual detection belt chain cross-conveyor type seedling transplanting machine. The device controls the air claw to move to the location of the inferior seedlings, clamps the inferior seedlings, and then moves the air claw back to place the inferior seedlings in the inferior seedling box. If new seedlings need to be replaced, the air claw needs to be controlled to move again, clamp the new seedlings, and fill the new seedlings into the tray hole where the inferior seedlings are just located, and finally reset the air claw. In summary, when the above device is actually used, if it is necessary to replace the plant seedlings in the tray hole, two or more back and forth movements are required, and the operation process is relatively cumbersome.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0033] Embodiment: Seedling planting device, as shown in the attached Figure 1-3 As shown, it includes a mounting frame 1, and a moving assembly 2 is provided on both sides of the mounting frame 1. The moving assembly 2 includes an axle, a moving wheel and a driving device for driving the axle to rotate, which are arranged on the side of the mounting frame 1. This is the existing technology and will not be described in detail here. A moving track 3 is provided on the mounting frame 1, a moving seat 4 is provided on the moving track 3, and a position adjustment frame is provided on the moving seat 4. The position adjustment frame includes a longitudinal adjustment mechanism, and the longitudinal adjustment mechanism includes a longitudinal slide rail 5 provided on the moving seat 4, and a longitudinal slider 12 is provided on the longitudinal slide rail 5. Controlling the longitudinal slide rail 5 can drive the longitudinal slider 12 and the structure thereon to move up and down. The position adjustment frame also includes a transverse adjustment mechanism, and the transverse adjustment mechanism includes a transverse slide rail 7 provided on the longitudinal slider 12, and a transverse slider 6 is provided on the transverse slide rail 7. Controlling the transverse slide rail 7 can drive the transverse slider 12 and the structure thereon to move transversely.

[0034] As attached Figure 11As shown, a placement plate 16 is provided in the middle of the mounting frame 1. When in use, the seedling tray is placed on the placement plate 16. A front crossbeam 9 is provided on the front side of the mounting frame 1, and a rear crossbeam 11 is provided on the rear side of the mounting frame 1. The placement plate 16 is provided between the front crossbeam 9 and the rear crossbeam 11. A vertical plate 10 is provided on the side of the front crossbeam 9. The side of the placement plate 16 is hinged to the vertical plate 10, and a torsion spring is provided at the hinge. The side of the rear crossbeam 11 is connected to a fork plate 17 via a telescopic assembly 14. In the initial state, the fork plate 17 supports the bottom of the placement plate 16, so that the placement plate 16 will not rotate downward due to the pressure of the seedling tray, and will remain in a horizontal or slightly inclined state. As shown in the attached Figure 13 As shown, the telescopic assembly 14 includes a servo 141 fixed to the side of the rear crossbeam 11. The output shaft of the servo 141 is connected to an adjustment plate 142. The end of the adjustment plate 142 is hinged to a connecting plate 143. The end of the connecting plate 143 is hinged to the side of the plug plate 17. The telescopic assembly 14 also includes a sleeve 145 fixed to the side of the rear crossbeam 11. The sleeve 145 is internally provided with a slide rod 144. One end of the slide rod 144 extends out of the sleeve 145 and is connected to the plug plate 17.

[0035] When the plant seedlings in the seedling tray are used up, the steering engine 141 is started, and the output shaft of the steering engine 141 drives the adjustment plate 142 to rotate, and the adjustment plate 142 pulls the plug plate 17 to move through the connecting plate 143. Since the side of the plug plate 17 is connected to the slide bar 144, the fork plate 17 can only move forward and backward. Therefore, when the connecting plate 143 moves, it can drive the plug plate 17 to move backward, so that the fork plate 17 no longer supports the placement plate 16. Figure 12 As shown, the placing plate 16 rotates downward under the pressure of the seedling tray, and the seedling tray slides off the placing plate 16. When the seedling tray completely leaves the placing plate 16, the placing plate 16 rotates upward and resets under the elastic force of the torsion spring, and then the steering engine 141 is controlled to rotate in the opposite direction, driving the inserting plate 17 to move forward, supporting the bottom of the placing plate 16, and then placing a new seedling tray on the placing plate 16. The above operation can realize the replacement function of the seedling tray, which is convenient for operation.

[0036] The side of the position adjustment frame is provided with a claw changing mechanism, as shown in the attached Figure 4 and attached Figure 5As shown, the claw-changing mechanism includes a mounting base 25, which is mounted on the surface of the transverse slider 6. A drive motor 15 is mounted on the side of the mounting base 25, and the output shaft of the drive motor 15 is connected to the driving gear 13. A central shaft 23 is rotatably connected to the side of the mounting base 25 via a bearing. A driven gear 22 is mounted on the central shaft 23 and meshes with the driving gear 13. A triangular plate 8 is mounted on the surface of the central shaft 23, and the side of the triangular plate 8 is connected to the side of the driven gear 22. Planetary gears are mounted inside the triangular plate 8. The planetary gears include a central gear 24 connected to the central shaft 23 and auxiliary gears 18 mounted at the corners of the triangular plate 8, meshing with the central gear 24. Auxiliary shafts 19 are rotatably connected to the corners of the triangular plate 8 via bearings, and the auxiliary gears 18 are mounted on the auxiliary shafts 19. Two of the auxiliary shafts 19 extend through the triangular plate 8 and are connected to the gripping assembly 20. Another auxiliary shaft 19 extends through the triangular plate 8 and is connected to the soil compacting assembly 21.

[0037] When in use, the grabbing assembly 20 and the soil compacting assembly 21 can be driven by the driving motor 15 to rotate and switch the functions. The specific operation is as follows: For example, in the initial state, as shown in the attached Figure 4 As shown, the soil compacting assembly 21 is located on the upper side. When soil compaction is required, the driving motor 15 can be started to drive the driving gear 13 to rotate, thereby driving the driven gear 22 to rotate, causing the central shaft 23 and the triangular plate 8 to rotate. The triangular plate 8 drives the auxiliary shaft 19 to rotate, thereby driving the grabbing assembly 20 and the soil compacting assembly 21 to rotate, and rotating the soil compacting assembly 21 to the bottom, as shown in the figure. Figure 6 As shown, when central shaft 23 rotates, central gear 24 also rotates synchronously. Furthermore, during this rotation, auxiliary gear 18 meshes with central gear 24, causing auxiliary gear 18 to "crawl" along the central gear. This means that auxiliary shaft 19 also rotates, causing the gripping assembly 20 and compacting assembly 21 to remain in a drooping position. In summary, the present invention allows for adjustment of the gripping and compacting assemblies simply by controlling the rotation of drive motor 15, enabling switching between different functions and simplifying operation.

[0038] As attached Figure 7As shown, the grabbing assembly 20 includes a first fixed plate 201 connected to the end of the auxiliary shaft 19. A first motor 202 is provided on the side of the first fixed plate 201. The output shaft of the first motor 202 passes through the first fixed plate 201 and is connected to a first rotating arm 203. Both ends of the first rotating arm 203 are hinged to a first connecting rod 204. A first limiting rod 207 is fixedly connected to the side of the first fixed plate 201. A first limiting block 205 is slidably sleeved on the first limiting rod 207. A first movable plate 206 is provided on the surface of the first limiting block 205. The first limiting rod 207 and the first limiting block 205 are provided so that the first movable plate 206 can only move horizontally, acting as a guide. The upper end of the first movable plate 206 is hinged to the first connecting rod 204 , and the lower end of the first movable plate 206 is hinged with a clamping claw 208 , which is a shovel-shaped structure; a connecting piece 209 is provided on the upper side of the clamping claw 208 , and the two connecting pieces 209 are hinged to each other.

[0039] In the initial state, if Figure 7 As shown, the two clamping jaws 208 are in a closed state. The first motor 202 is started to drive the first rotating arm 203 to rotate. The first rotating arm 203 drives the first movable plate 206 to move horizontally along the first limiting rod 207 through the first connecting rod 204. The two first movable plates 206 move closer to each other, driving the upper ends of the two clamping jaws 208 closer to each other. Since the upper sides of the clamping jaws 208 are hinged by the connecting member 209, when the upper ends of the clamping jaws 208 move closer to each other, the lower ends will move away from each other, and the clamping jaws 208 will be opened. Figure 8 When the clamping jaws 208 need to be closed, it is only necessary to control the first motor 202 to rotate in the opposite direction, so that the two movable plates 205 move away from each other, drive the upper ends of the clamping jaws 208 away from each other, and drive the lower ends of the clamping jaws 208 closer together until the clamping jaws 208 are closed.

[0040] As attached Figure 9As shown, the soil compacting assembly 21 includes a second fixed plate 211 connected to the end of the auxiliary shaft 19, and a second motor 212 is provided on the side of the second fixed plate 211. The output shaft of the second motor 212 passes through the second fixed plate 211 and is connected to a second rotating arm 213, and both ends of the second rotating arm 213 are hinged with a second connecting rod 214; the side of the second fixed plate 211 is fixedly connected to a second limiting rod 216, and the side of the second limiting rod 216 is slidably sleeved with a second limiting block 217, and the surface of the second limiting block 217 is provided with a second movable plate 215, the upper end of the second movable plate 215 is hinged to the second connecting rod 214, and the lower end of the second movable plate 215 is fixedly connected to a soil compacting plate 218. The soil pressing plate 218 includes a vertical section connected to the second movable plate 215, the lower end of the vertical section is connected to a horizontal section, and an arc groove is provided in the middle of the horizontal section. The arc groove can facilitate the plant seedlings to pass through the arc groove when the soil pressing plate 218 moves downward to press the soil, and will not cause squeezing and damage to the plant seedlings.

[0041] Similar to the grab assembly 20, the second motor 212 is started, and the second motor 212 drives the second rotating arm 213 to rotate, thereby driving the two second movable plates 215 to move horizontally along the second limiting rod 216 through the second connecting rod 214. The two second movable plates 215 move away from each other, thereby driving the soil pressing plate 218 to move away from each other, and the soil pressing plate 218 can be opened. Figure 10 On the contrary, the second motor 212 rotates in the reverse direction, driving the two second movable plates 215 to move closer to each other, thereby driving the two soil pressing plates 218 to move closer to each other.

[0042] Working principle: When in use, as shown in the attached Figure 14As shown, the device is placed on a platform, and the platform is flush with the platform height where the seedling tray is placed, so that the device can be smoothly moved to the seedling tray. The device is moved to the position where the seedling tray is located by a mobile assembly, and then the claw mechanism is driven to move laterally by the position adjustment frame, the position of the claw mechanism is adjusted, and then the claw mechanism is controlled to move downward, and the plant seedlings in the seedling tray are clamped by the grab assembly 20 (for convenience of description, the clamping jaw 208 in the grab assembly 20 is named as No. 1 clamping jaw). The mobile seat 4 is then driven to move by the mobile track 3, thereby driving the position adjustment frame and the claw mechanism to move forward, and the claw mechanism is moved to the top of the seedling tray. The grab assembly is adjusted in position by a drive motor 15, and empty clamping jaws 208 (for convenience of description, the clamping jaws 208 are named as No. 2 clamping jaws) are rotated to the bottom, and then the claw mechanism is controlled to move downward, and the plant seedlings to be replaced or the soil in the empty dish hole are grabbed out. Adjust the position of the claw changing mechanism again, rotate the No. 1 clamping jaw downward, control the No. 1 clamping jaw to move downward, and place the plant seedling into the corresponding hole. Then adjust the position of the claw changing mechanism, rotate the soil pressing assembly 21 downward, and use the soil pressing assembly 21 to compact and level the soil in the replaced hole.

[0043] After the replacement is completed, the position adjustment frame is driven to move backward by the movable track 3, the position of the claw changing mechanism is adjusted, and the soil or plant seedlings in the No. 2 clamp are placed into the corresponding holes of the seedling tray to complete the seedling replacement or replacement operation.

[0044] Furthermore, in order to improve the intelligence level of the device, a camera recognition device can be set on the front side of the device to automatically identify empty holes or poor quality seedlings in the seedling tray to be filled, making the device more automated.

[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements within the scope of the claims of the present invention are intended to be included within the scope of protection of the present invention.
