DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10 As shown, a forestry seedling raising device and a seedling raising method include two symmetrically arranged side plates 1, a rotating shaft 13 is rotatably installed between the two side plates 1, and a plurality of side plates 1 are connected to the two side plates 1. Figure 1-Figure 3As shown, a plurality of cantilevers 8 are fixedly arranged at the outer peripheral wall of the rotating shaft 13, and the plurality of cantilevers 8 are distributed in a circular array on the outer side of the rotating shaft 13, and a slider 11 is slidably mounted on the cantilever 8, and a sleeve 7 is rotatably mounted on the inner side of the slider 11, and a loading platform 4 is arranged between two cantilevers 8 on the same horizontal plane, and a support rod 12 is fixedly arranged between the loading platform 4 and the sleeve 7. Through this structure, when the rotating shaft 13 rotates, the loading platform 4 can be synchronously driven to rotate through the cantilever 8, and the loading platform 4 is always in a horizontal state; Reference Figure 2 As shown, a guide plate 2 is fixedly arranged between the two side plates 1, and a water pump is installed on the outside of one of the side plates 1 and near the bottom end. The output end of the water pump is connected with the guide plate 2 through a nozzle 9. In actual use, a plurality of nozzles can be installed at the bottom of the guide plate 2. Through this structure, when the cantilever 8 drives the loading platform 4 to rotate to the bottom of the guide plate 2, the nozzle under the guide plate 2 can be used to water the seedlings on the loading platform 4.

[0021] During the process of the cantilever 8 driving the loading platform 4 to rotate, as the loading platform 4 gradually deflects upward, the distance between the loading platform 4 and the guide plate 2 will gradually decrease, resulting in the inability to evenly water the seedlings on the loading platform 4. To address this problem, the present scheme slides and installs a limit plate 6 at the inner position of the side plate 1. The limit plate 6 is generally in the shape of a "U" character and the limit plate 6 can move in the vertical direction relative to the side plate 1. The outer end surface of the slider 11 is elastically installed with a limit shaft 18 that cooperates with the limit plate 6. The slider 11 is provided with a clamping assembly that cooperates with the cantilever 8. When the slider 11 rotates to the limit plate 6 so that the limit shaft 18 is inserted into the inside of the limit plate 6, the clamping assembly on the slider 11 is separated from the cantilever 8, so that the limit shaft 18 at one end of the slider 11 can slide along the limit plate 6. Specifically, refer to Figure 4 As shown, the inner bottom surface of the limiting plate 6 is set as an inclined guide surface 604. When the limiting shaft 18 is inserted into the limiting plate 6, the limiting shaft 18 can move downward along the guide surface 604. During this process, the loading platform 4 can pass through the guide plate 2, so as to water the seedlings on the loading platform 4. The clamping assembly includes a positioning block 26 that slidably cooperates with the slider 11, and is combined with Fig.11 As shown, the positioning block 26 can move in the vertical direction relative to the slider 11, and the cantilever 8 is provided with a slide groove that slides with the slider 11, and a positioning groove that cooperates with the positioning block 26 is opened on the top wall of the slide groove. Fig.11 As shown, a top block 27 is provided below the positioning block 26, and the positioning block 26 and the top block 27 are elastically matched. Figure 11-Figure 14 As shown, a mounting groove for slidingly cooperating with the top block 27 is provided on the outer peripheral wall of the limit shaft 18, so that the limit shaft 18 can slide relative to the top block 27; The front and rear side walls of the installation groove are both provided with strip grooves 1801, and the side of the top block 27 close to the strip groove 1801 is fixed with a guide rod 2702, so that the guide rod 2702 slides in the strip groove 1801, and the guide rod 2702 is fixed with the guide rod 2702. Figure 12-13 As shown, a notch 1802 is provided on the inner bottom surface of the strip groove 1801, and a guide plate 29 is provided on the bottom surface of the strip groove 1801 on one side of the notch 1802, the guide plate 29 is elastically matched with the limiting shaft 18 and the guide plate 29 can rotate relative to the limiting shaft 18, and a side surface of the notch 1802 close to the guide plate 29 is inclined and is recorded as a slope 1803; Combination Figure 3 , Figure 5 As shown, the bottom surface of the limit plate 6 is provided with an inclined extrusion surface 605, and a baffle 603 is fixedly provided on one side of the limit plate 6 close to the side plate 1. When in use, when the limit shaft 18 rotates to the limit plate 6, the limit shaft 18 can be compressed into the slider 11 through the extrusion surface 605. In this process, the guide rod 2702 can slide along the strip groove 1801 and drive the guide plate 29 to deflect, so that the guide plate 29 covers the slot 1802, thereby preventing the guide rod 2702 from falling to the bottom. In the slot 1802, when the limit shaft 18 is aligned with the limit plate 6, the limit shaft 18 can pop out and be inserted into the limit plate 6, so that the limit shaft 18 fits with the baffle 603. During this process, the guide rod 2702 can move toward the direction close to the guide plate 29 and finally fall into the slot 1802, thereby separating the positioning block 26 from the positioning groove, so that the slider 11 and the cantilever 8 are out of engagement, and the limit shaft 18 can slide downward along the inclined guide surface 604 on the limit plate 6.

[0022] Combination Figure 4-Figure 5 As shown, a notch 606 is provided on the inner bottom surface of the limiting plate 6 , so that the limiting shaft 18 can be guided out from the notch 606 . Specifically, the notch 606 is located at the lower end of the guide surface 604 .

[0023] In actual use, the rotating shaft 13 is driven to rotate by an external power component, and the rotating shaft 13 can drive the loading platform 4 to rotate through the cantilever 8. When the loading platform 4 rotates to the vicinity of the limiting plate 6 so that the limiting shaft 18 is in contact with the extrusion surface 605, as the cantilever 8 continues to rotate, the limiting shaft 18 can be compressed into the slider 11 through the extrusion surface 605. According to the above analysis, as the limiting shaft 18 shrinks into the slider 11, the guide rod 2702 will move along the strip. The groove 1801 slides and drives the guide plate 29 to flip, so that the guide plate 29 covers the groove 1802, thereby preventing the guide rod 2702 from falling into the groove 1802. When the guide rod 2702 passes through the guide plate 29 and falls to the bottom surface of the strip groove 1801, the guide plate 29 can deflect and reset. When the limit shaft 18 is aligned with the limit plate 6, the limit shaft 18 can be inserted into the limit plate 6 and fit with the baffle 603. 3, so that the limit shaft 18 cannot be fully ejected, but as the limit shaft 18 pops outward relative to the slider 11, the guide rod 2702 can move toward the direction close to the guide plate 29 and finally fall into the notch 1802, so that one end of the positioning block 26 can be moved out of the positioning groove, so that the slider 11 and the cantilever 8 are out of the clamping relationship. At this time, the limit shaft 18 can move downward along the inclined guide surface 604 on the limit plate 6. Of course, since the slider 11 always slides in the slide groove, the cantilever 8 limits the slider 11 so that the limit shaft 18 can slide stably relative to the limit plate 6. At this time, the loading platform 4 below the slider 11 moves approximately on a horizontal plane. When the loading platform 4 passes through the guide plate 2, the seedlings on the loading platform 4 can be watered through the nozzle below the guide plate 2. Due to the approximately horizontal movement of the loading platform 4, the water source can be evenly irrigated on the loading platform 4; When the loading platform 4 passes the guide plate 2, the limit shaft 18 can move to the notch 606 on the limit plate 6, so that the limit shaft 18 can be guided out through the notch 606. After the limit shaft 18 is guided out of the limit plate 6, the limit shaft 18 can be further ejected due to the loss of the restriction of the baffle 603. During this process, the guide rod 2702 will continue to move toward the direction close to the guide plate 29, and the pressure of the slope 1803 on the notch 1802 on the guide rod 2702 can drive the guide rod 2702 to move upward. , so that the guide rod 2702 can reach the guide plate 29 and finally pass through the guide plate 29. During this process, the guide rod 2702 can drive the top block 27 and the positioning block 26 to move upward. As the cantilever 8 deflects downward, the slider 11 will slide relative to the cantilever 8 in the direction away from the rotating shaft 13. When the positioning block 26 on the slider 11 slides to be aligned with the positioning groove, the positioning block 26 can pop out and be inserted into the positioning groove, so that the slider 11 and the cantilever 8 are re-locked, which is convenient for the next use.

[0024] To sum up, this device, through the provision of a clamping assembly, enables the slider 11 to release the locking relationship with the cantilever 8 when the limit shaft 18 is inserted into the limit plate 6, so that the limit shaft 18 can slide relative to the limit plate 6. In the process of the loading platform 4 passing through the guide plate 2, the seedlings can be watered by the nozzle on the guide plate 2, and the nearly horizontal movement of the loading platform 4 allows the water source to be evenly irrigated on the loading platform 4. On the one hand, it can save water resources, and on the other hand, it is also beneficial to the growth of seedlings.

[0025] like Figure 1-Figure 10 As shown, as a further development of the above scheme, in this scheme, a guide block 601 is fixedly arranged on the outer side surface of the limit plate 6 and near the two ends, a recessed portion slidably matched with the guide block 601 is provided on the side plate 1, and a vertical rod is fixedly arranged at the recessed portion, the vertical rod passes through the guide block 601 and slidably matches with it, and a through slot is also provided at the middle position of the side plate 1, a lifting block 602 is slidably arranged at the through slot, and the lifting block 602 is fixedly arranged on the outer side surface of the limit plate 6, and further, a screw rod 10 is rotatably installed at the through slot, and the screw rod 10 passes through the lifting block 602 and is threadedly connected with it; Reference Figure 5-Figure 6 As shown, the positions near both ends of the screw rod 10 are both bare rod structures, and the bottom end of the screw rod 10 is fixedly sleeved with a driven bevel gear, a boss 101 is fixedly provided on the inner side surface of the side plate 1, and a connecting shaft 15 is provided above the boss 101. An active bevel gear meshing with the driven bevel gear is fixedly provided at one end of the connecting shaft 15 close to the screw rod 10, and a convex portion is integrally formed on the top surface of the boss 101. The connecting shaft 15 passes through the convex portion and rotatably cooperates with the convex portion, and a spur gear 23 is rotatably provided at one end of the connecting shaft 15 away from the screw rod 10 through a bearing; Combination Figure 5-Figure 6 , Fig.10 As shown, a magnetic block 16 is slidably provided on the end face of the connecting shaft 15 away from the screw rod 10, and a protrusion 24 is elastically installed on the outer peripheral wall of the connecting shaft 15, and a groove matching with the protrusion 24 is provided on the inner wall of the spur gear 23, and a pull rope 25 is fixedly provided between the protrusion 24 and the magnetic block 16, and the pull rope 25 passes through the connecting shaft 15 and slidably cooperates with it. An arc plate 5 is fixedly provided on the outer side surface of the cantilever 8, and a meshing groove meshing with the spur gear 23 is integrally formed on the inner wall of the arc plate 5. The transmission tooth 501, specifically, during the rotation of the cantilever 8, the transmission tooth 501 will mesh with the spur gear 23, and an arc-shaped magnetic strip 17 is slidably provided on the inner wall of the arc plate 5. Specifically, an arc-shaped groove is opened on the inner wall of the arc plate 5, and the magnetic strip 17 is slidably provided in the arc-shaped groove. The side of the magnetic strip 17 opposite to the magnetic block 16 has different magnetic poles, and a locking bolt 502 is threadedly connected to the outer side surface of the arc plate 5, and one end of the locking bolt 502 extends to the magnetic strip 17.

[0026] Reference Figure 7-Figure 9 As shown, the top and bottom surfaces of the through groove are both provided with round holes for installing the first coil spring 19. Specifically, the first coil spring 19 is sleeved on the outside of the screw rod 10, and the two ends of the first coil spring 19 are respectively fixedly connected to the outer wall of the screw rod 10 and the inner wall of the round hole. A card slot 1001 is provided on the outer peripheral wall of the screw rod 10 and near the top. A card block 22 matching the card slot 1001 is provided on the side plate 1. Specifically, a connecting block 20 is elastically provided at one end of the card block 22 away from the screw rod 10. The connecting block 20 is made of iron. An electromagnet 21 is provided at one end of the connecting block 20 away from the screw rod 10. A first spring is fixedly provided between the electromagnet 21 and the connecting block 20. Fig. 9 As shown, one end of the block 22 close to the screw rod 10 is set as an inclined surface 2201. Through this structure, when the block 22 is aligned with the slot 1001, the screw rod 10 can only rotate in one direction relative to the block 22.

[0027] In actual use, the height of the limiting plate 6 can be adjusted according to the growth height of the seedlings on each loading platform 4. Specifically, the position of the magnetic strip 17 relative to the arc plate 5 can be adjusted. For example, when the seedlings on the loading platform 4 grow high, refer to Figure 5 As shown, the magnetic strip 17 can be adjusted downward relative to the arc plate 5. When the cantilever 8 rotates to make the arc plate 5 rotate to the spur gear 23, the meshing of the spur gear 23 and the transmission tooth 501 can drive the connecting shaft 15 to rotate, and then the meshing of the active bevel gear and the driven bevel gear drives the screw rod 10 to rotate, and the lifting block 602 is driven downward by the screw rod 10, and the lifting block 602 can synchronously drive the limit plate 6 to move downward. With the continuous rotation of the cantilever 8, the magnetic strip 17 will overlap with the end of the connecting shaft 15, and then the suction force of the magnetic strip 17 on the magnetic block 16 can pull the pull rope 25, so that the cam The block 24 is disengaged from the spur gear 23. At this time, the transmission tooth 501 can only drive the spur gear 23 to rotate alone, and the cooperation between the clamping block 22 and the clamping groove 1001 can prevent the screw rod 10 from rotating in the opposite direction. Therefore, by adjusting the position of the magnetic strip 17 relative to the arc plate 5, the number of circles of the connecting shaft 15 driven by the meshing of the transmission tooth 501 and the spur gear 23 can be controlled, thereby controlling the position of the limit plate 6 relative to the side plate 1. According to the above analysis, when the seedling height is high, the limit plate 6 can move downward a long distance, thereby preventing the water source from being too close to the seedling during irrigation, which is beneficial to protecting the seedling. Combination Figure 5As shown, a detection unit 14 is installed at the notch 606. The detection unit 14 can be a pressure sensor or an infrared sensor, etc. The detection unit 14 is electrically connected to the above-mentioned electromagnet 21. The specific circuit connection between the detection unit 14 and the electromagnet 21 is a mature technical means and is not elaborated here. When the limit shaft 18 is guided out through the notch 606, the detection unit 14 can be triggered, thereby prompting the electromagnet 21 to be energized. The suction force of the electromagnet 21 on the connecting block 20 can pull the card block 22, so that the card block 22 is disengaged from the card slot 1001, so that the first coil spring 19 can drive the lead screw 10 to rotate in the opposite direction, thereby driving the limit plate 6 to move upward and reset, which is convenient for the next use. Of course, the number of the lead screw 10 and the first coil spring 19 is not limited to one group.

[0028] In summary, during use, this device can adjust the position of the limit plate 6 on the side plate 1 according to the height of the seedlings on each loading platform 4, thereby preventing the nozzle under the guide plate 2 from being too close to the seedlings, which is beneficial to protecting the seedlings.

[0029] like Figure 1-Figure 10 As shown, a bottom plate is fixedly arranged below the side plate 1. In order to drive the rotating shaft 13 to rotate, a fixed shaft is integrally formed at the end of the rotating shaft 13. The fixed shaft passes through the side plate 1 and rotates with it.
