[0002] In the cultivation of Chinese medicinal herbs, in order to ensure the herb's resistance, it is necessary to cultivate the seedlings to guarantee the herb's performance. Current seedling cultivation for Chinese medicinal herbs is usually carried out in nurseries, hotbeds, or greenhouses, with the successfully cultivated seedlings then ready for transplanting into the ground. This "carpet-style" seedling cultivation method requires a large area, is difficult to manage, and has high site costs.

[0003] Chinese invention patent CN119422703A discloses a seedling cultivation device for Chinese medicinal herbs, including a seedling rack. At least one side of the seedling rack is equipped with a ring. One end of the ring is rotatably connected to the seedling rack, and its rotation plane forms an angle of 30°-90° with the horizontal plane. Multiple cantilever shafts are circumferentially spaced at the other end of the ring. Each cantilever shaft extends along the axial direction of the ring, with one end fixedly connected to the ring and the other end rotatably connected to a hanging arm assembly. The upper end of each hanging arm assembly is rotatably connected to the corresponding cantilever shaft, and the lower end is rotatably connected to a seedling box with an upwardly open structure.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-10 The present invention will describe the above technical solution in detail through the following embodiments:

[0036] A medicinal herb cultivation and seedling raising device includes a supporting base frame 1. A vertically positioned seedling circular frame 2 is mounted on the top of the supporting base frame 1. A horizontally positioned drive shaft 21 is rotatably mounted in the center of the seedling circular frame 2. Several first connecting rods 211 are arranged at equal angles around the drive shaft 21 on both sides. A first mounting ring 3 is mounted on each of the first connecting rods 211, rotatably mounted on the side wall of the seedling circular frame 2. First adjusting mechanisms 4 are also provided on both sides of the drive shaft 21. Second adjusting mechanisms 5 and second mounting rings 6 are mounted on the first adjusting mechanisms 4. Several second connecting rods 61 are arranged at equal angles around the inner side wall of the second mounting rings 6, and the second connecting rods 61 are connected to the first adjusting mechanisms 4. The mechanism 5 is equipped with a third mounting ring 7. The inner wall of the third mounting ring 7 is provided with several third connecting rods 71 ​​arranged at equal angles around its circumference. The third connecting rods 71 ​​are connected to the second adjustment mechanism 5. The diameter of the first mounting ring 3 is larger than the diameter of the second mounting ring 6, and the diameter of the second mounting ring 6 is larger than the diameter of the third mounting ring 7. Several evenly distributed cantilever shafts 31 are installed on the outer walls of the first mounting ring 3, the second mounting ring 6, and the third mounting ring 7. A support sleeve 32 is rotatably mounted on the cantilever shaft 31. A detachable seedling box 33 is mounted on the support sleeve 32. The seedling frame 2 is also provided with a drive mechanism 8 for driving the rotation of the active shaft 21 and a spraying mechanism 9 for watering. The drive mechanism 8 and the spraying mechanism 9 are connected in transmission.

[0037] This invention employs a first mounting ring 3, a second mounting ring 6, and a third mounting ring 7 to increase the number of seedling boxes 33 that can be installed. That is, within a limited space, the number of seedlings cultivated is increased. The diameters of the first mounting ring 3, the second mounting ring 6, and the third mounting ring 7 are also different. The third mounting ring 7 can be retracted into the second mounting ring 6 by the second adjustment mechanism 5, and the second mounting ring 6 can also be retracted into the first mounting ring 3 by the first adjustment mechanism 4, thus improving flexibility.

[0038] In use, the second mounting ring 6 and the third mounting ring 7 are first extended from the first mounting ring 3 through the first adjustment mechanism 4. The first adjustment mechanism 4 includes a first locking rod 41 and a telescopic bushing 42. The tail end of the first locking rod 41 is provided with a limiting plate 43. A first spring 44 is sleeved on the first locking rod 41. The tail end of the telescopic bushing 42 is provided with a first slide block 421 that slides and engages with the first locking rod 41. The inner side wall of the telescopic bushing 42 is provided with several guide slides 422 that are equidistant from its circumference. The outer walls on both sides of the drive shaft 21 are provided with several strip-shaped slide grooves 212 that engage with the guide slides 422. The two sides of the drive shaft 21 are provided with two spaced first insertion holes 213 that engage with the first locking rod 41. All the second connecting rods 61 are fixedly connected to the outer wall of the telescopic bushing 42. The two ends of the first spring 44 are fixedly connected to the limiting plate 43 and the first slide block 421, respectively.

[0039] By pushing the first locking rod 41 outward through the limiting plate 43, the head of the first locking rod 41 can gradually disengage from the corresponding first insertion hole 213, the first spring 44 is compressed, and then the telescopic sleeve 42 loses its locking force. Subsequently, the telescopic sleeve 42 is moved outward on the drive shaft 21. When the first locking rod 41 aligns with another first insertion hole 213, the elastic force of the first spring 44 can drive the limiting plate 43 and the first locking rod 41 to move in opposite directions. Then the first locking rod 41 can be inserted into another first insertion hole 213, thereby locking the telescopic sleeve 42. After the telescopic sleeve 42 moves, it can drive all the second connecting rods 61 and the second adjusting mechanism 5 to move synchronously. The second mounting ring 6 also extends out from the first mounting ring 3. The cooperation between the guide slide 422 and the strip groove 212 can not only guide the lateral movement of the telescopic sleeve 42, but also allow the telescopic sleeve 42 to rotate synchronously with the drive shaft 21, avoiding the phenomenon of the telescopic sleeve 42 deflecting.

[0040] Subsequently, the third mounting ring 7 extends from the second mounting ring 6 through the second adjustment mechanism 5. The second adjustment mechanism 5 includes several strip-shaped sliding frames 51, and a synchronous slider 512 is slidably arranged inside the strip-shaped sliding frame 51. Each of the two ends of one of the strip-shaped sliding frames 51 is provided with a second sliding seat 511. A second locking rod 52 is slidably arranged on each of the second sliding seats 511. A pull plate 53 is provided at the tail end of each of the two second locking rods 52. A second spring 54 is sleeved on the second locking rod 52. The two ends of the second spring 54 are fixedly connected to the second sliding seat 511 and the pull plate 53, respectively. A second insertion hole is provided on the side wall of one of the synchronous sliders 512 to engage with the second locking rod 52. All the strip-shaped sliding frames 51 are arranged at equal angles around the circumference of the telescopic bushing 42 on the outer wall of the telescopic bushing 42. All the third connecting rods 71 ​​are fixedly connected to all the synchronous sliders 512, respectively.

[0041] Pulling the pull plate 53 outward causes the two second locking rods 52 to move outward synchronously. At the same time, the two second springs 54 are stretched synchronously, and the heads of the second locking rods 52 that are inserted into the second insertion holes gradually disengage from the corresponding synchronous sliders 512. After that, the corresponding synchronous sliders 512 lose their lock. Then, by pulling the third connecting rod 71 outward, the third connecting rod 71 can drive the third mounting ring 7. The third mounting ring 7 will drive all the third connecting rods 71 ​​to move outward, and all the synchronous sliders 512 will move outward synchronously. Then, the synchronous slider 512 with the second insertion hole gradually connects with another second locking rod 52. The elastic force of the two second springs 54 can drive the pull plate 53 and the two second locking rods 52 to move in opposite directions synchronously. The second locking rod 52 that connects with the second insertion hole is inserted into the second insertion hole. Then, the synchronous slider 512 is locked, and the third mounting ring 7 also extends out from the second mounting ring 6. The first mounting ring 3, the second mounting ring 6, and the third mounting ring 7 are completely misaligned.

[0042] Furthermore, both the first locking rod 41 and the second locking rod 52 have an outer chamfer at their ends. The outer chamfer of the first locking rod 41 can improve the smoothness of its entry into the first insertion hole 213, and the outer chamfer of the second locking rod 52 can improve the smoothness of its entry into the second insertion hole.

[0043] Since the seedling box 33 is detachable, it is convenient to directly install the seedling box 33 containing seedlings onto all the support sleeves 32. The bottom of the support sleeve 32 is provided with an installation block 321. The installation block 321 is provided with a fourth insertion hole 322 with a polygonal cross section. A fixing rod 323 is inserted into the fourth insertion hole 322. One end of the fixing rod 323 is provided with a screw 324. A nut 325 is screwed onto the screw 324. The other end of the fixing rod 323 is provided with a handle 326. The top of the seedling box 33 is provided with two hangers 331. The hangers 331 are provided with a fifth insertion hole 332 that is inserted and matched with the fixing rod 323.

[0044] Overlap the two fifth insertion holes 332 on the two brackets 331 with the fourth insertion hole 322, then insert the fixing rod 323 into the fourth insertion hole 322 and the two fifth insertion holes 332, and then fix the nut 325 onto the screw 324, so that the seedling box 33 can be quickly installed onto the support rotating sleeve 32. Of course, removing the seedling box 33 is also very convenient. Just remove the nut 325 and then pull out the fixing rod 323 through the lever 326.

[0045] When installing the seedling box 33, the drive mechanism 8 is also needed to drive the active shaft 21 to rotate, so that the seedling box 33 can be installed sequentially onto all the support sleeves 32 on the first mounting ring 3, the second mounting ring 6 and the third mounting ring 7. The drive mechanism 8 includes two first bearing seats 81, a drive shaft 82, a worm gear 83, a worm 84 and a drive handle 85. One end of the drive shaft 82 is provided with a polygonal cross-section docking block 821. The drive handle 85 is provided with a docking groove for the docking block 821 to be inserted and fitted. The two first bearing seats 81 are symmetrically arranged on the outer walls of the two sides of the seedling circular frame 2. The drive shaft 82 is rotatably mounted on the two first bearing seats 81. The worm gear 83 is mounted on the active shaft 21. The worm 84 is mounted on the drive shaft 82. The worm 84 meshes with the worm gear 83. The spraying mechanism 9 is connected to the drive shaft 82 for transmission.

[0046] The drive handle 85 is inserted into the docking slot and then the drive shaft 82 is rotated by the drive handle 85 to rotate on the two first bearing seats 81. Alternatively, the drive shaft 82 can be rotated by a motor. After the drive shaft 82 rotates, it drives the worm gear 84 to rotate synchronously. The worm gear 84 drives the worm wheel 83 to rotate, and the worm wheel 83 drives the drive shaft 21 to rotate. The drive shaft 21 drives the two first mounting rings 3, the two second mounting rings 6, and the two third mounting rings 7 to rotate synchronously. The position of the support rotating sleeve 32 on the first mounting ring 3, the second mounting ring 6, and the third mounting ring 7 is also adjusted by rotating around the axis of the drive shaft 21.

[0047] After the seedling box 33 is installed, the watering operation can be performed on all the seedling boxes 33 through the cooperation between the drive mechanism 8 and the spraying mechanism 9.

[0048] The spraying assembly 91 includes a second bearing seat 911, a linkage slide rail 912, and two vertical shafts 913. A transmission rod 914 is rotatably mounted on the second bearing seat 911. The bottom of the transmission rod 914 has a first bevel gear 915, and the top of the transmission rod 914 has a transmission disc 916. An eccentric shaft 917 is mounted on the transmission disc 916, and a linkage plate 918 is rotatably mounted on the eccentric shaft 917. A linkage slider 9121 is slidably mounted on the linkage slide rail 912. A double-sided rack 9122 is mounted on the top of the linkage slider 9121, and a hinge shaft 9123 is mounted at one end of the double-sided rack 9122. A synchronous rotating sleeve 9131 is rotatably mounted on the vertical shafts 913, and a support cantilever 9132 is mounted on the top of the synchronous rotating sleeve 9131. The head end of the arm 9132 is provided with an adjustment groove 9133, and the adjustment groove 9133 is provided with an adjustable spray head 9134.

Two vertical shafts 913 are symmetrically arranged on both sides of the linkage slide 912. Both linkage gears 9135 mesh with the double-sided rack 9122. Both spray heads 9134 are connected to the water supply component 92 through pipes.

[0049] The water supply assembly 92 includes a water supply tank 921 and a pumping cylinder 922. One end of the water supply tank 921 is provided with a water inlet pipe 9211 communicating with its interior. A pumping plug is slidably installed inside the pumping cylinder 922.

The support cantilever 9132 drives the spray head 9134 to swing synchronously. The placement angle of the spray head 9134 can be adjusted, thereby changing the spraying direction of the spray head 9134. Meanwhile, by stepping on the foot pedal 925 and then pressing it downwards, the foot pedal 925 causes the abutment rod 923 to move downwards on the third sliding seat 924, compressing the third spring 926. The abutment rod 923 then causes the pumping plug to move downwards within the pumping cylinder 922. Due to the action of the outlet check valve and the inlet check valve, the water in the pumping cylinder 922 can be squeezed into the outlet pipe 9222, and then the water is transported to the two... When the downward foot pressure applied to the foot pedal 925 is removed from the spray head 9134, the elastic force of the third spring 926 can drive the foot pedal 925 to move upward. The foot pedal 925 drives the abutment rod 923 and the pumping plug to move upward. Due to the action of the outlet check valve and the inlet check valve, the water in the water tank 921 is drawn into the pumping cylinder 922 through the inlet pipe 9221. This cycle continues, and the spray head 9134 can spray water continuously. The amount of water sprayed can be determined according to the number of foot pedals.

[0051] The present invention also includes a base 10, a turntable 12 is provided at the bottom of the supporting base frame 1, an adjusting shaft is provided at the bottom of the turntable 12, a rotating hole is provided on the base 10 to cooperate with the adjusting shaft, a detachable pin is provided on the turntable 12, and a plurality of third insertion holes are provided on the base 10 to cooperate with the pin.

[0052] The lateral swing angle of the entire support base frame 1 can be changed by adjusting the cooperation between the turntable 12, the rotating shaft and the rotating hole, which changes the lateral placement angle of the entire seedling round frame 2. The turntable 12 is locked by the pin and the third insertion hole, thereby locking the position of the support base frame 1 and the seedling round frame 2.
