An adjustment mechanism is provided on the positioning water supply mechanism, and the adjustment mechanism is used to adjust the amount of water supply.

[0028] The positioning water supply mechanism includes a connecting plate 51, which is fixedly connected to one side of the placement plate 31, and a bent handle 52 is fixedly connected to the side of the connecting plate 51. Bent side rods 53 are fixedly connected to both sides of the load-bearing frame 1, and each of the bent side rods 53 is slidably connected with an inclined surface limiting rod 54, and a reset spring 55 is connected between the inclined surface limiting rod 54 and the bent side rod 53. The inclined surface limiting rod 54 contacts the side of the connecting plate 51, and two wheel frames 56 are fixedly connected to the lower part of the connecting plate 51. A shunt pipe 57 is fixedly connected to the side of the load-bearing frame 1 away from the connecting plate 51, and an interface pipe 58 is fixedly connected to one side of the shunt pipe 57, and three water supply pipes 59 are fixedly connected to the side of the shunt pipe 57 away from the interface pipe 58, and a plurality of drip holes are opened at the lower part of each of the water supply pipes 59.

[0029] The adjusting mechanism includes a supporting bent rod 61, which is fixedly connected to the side of the load-bearing frame 1. A rotating rod 62 is rotatably connected to the upper part of the supporting bent rod 61, and a rotating handle 63 is fixedly connected to one end of the rotating rod 62. A clamping block 64 is fixedly connected to the rotating rod 62, and three grooves are opened on the clamping block 64. A limited bent rod 65 is fixedly connected to the upper part of the supporting bent rod 61, and a clamping rod 66 is slidably connected to the limited bent rod 65. A pressure spring 67 is connected between the clamping rod 66 and the limited bent rod 65, and the clamping rod 66 is located in one of the grooves on the clamping block 64. The end of the rotating rod 62 away from the rotating handle 63 is fixedly connected to the main The driving gear 68 is fixedly connected to the inner wall of each water supply pipe 59 with an adjusting ring 69, and three circular holes of different sizes are formed on the adjusting ring 69, and three square holes are formed on the adjusting ring 69. A connecting rod 610 is fixedly connected between all the adjusting rings 69 in each water supply pipe 59, and a transmission gear 611 is fixedly connected to one end of the connecting rod 610 close to the driving gear 68, and the transmission gear 611 is meshed with the driving gear 68. Two horizontal plates 612 are fixedly connected to the inner wall of the diversion pipe 57, and a linkage rack 613 is slidably connected between the two horizontal plates 612, and the linkage rack 613 is meshed with the three transmission gears 611.

[0030] In the actual seedling cultivation process, the operator first needs to place the vegetable seedlings in the cultivation pots 42, and then add a proper amount of soil to each cultivation pot 42. Then the operator connects the interface pipe 58 with the faucet. The operator can supply water to the seedlings by turning on the faucet. Initially, the drip hole at the bottom of the water supply pipe 59 is aligned with one of the circular holes on the adjustment ring 69. After the operator turns on the faucet, water enters the diversion pipe 57 through the interface pipe 58, and then enters the three water supply pipes 59, and finally passes through the adjustment ring 69 and the water supply pipe 59. The drip holes at the bottom of the 9 drip into the soil in the cultivation pot 42 below to achieve drip irrigation for the seedlings. Excess water will flow into the load-bearing frame 1 through the leaking holes at the bottom of the cultivation pot 42, and then flow out through the water guide holes on both sides of the load-bearing frame 1 under the diversion effect of the arc panel 2. When the seedlings grow to different periods, the seedlings have different water requirements. Then the operator can rotate the handle 63 120°. The rotation of the handle 63 will drive the block 64 to rotate 120°, thereby causing the clamping rod 66 to be clamped into another groove on the clamping block 64. The rotation of the handle 63 will drive the driving gear 68 to rotate, and the three connecting rods 610 will be driven to rotate together through the transmission gear 611 and the linkage rack 613. The rotation of the connecting rod 610 will drive the adjusting ring 69 to rotate 120 degrees. Since there are three circular holes of different sizes on the adjusting ring 69, rotating the adjusting ring 69 120 degrees can change the circular hole on the adjusting ring 69 that is aligned with the drip hole of the water supply pipe 59, thereby changing the amount of water dripping from the water supply pipe 59, so that it is convenient to adjust the water supply to the seedlings according to different needs. Then, when the seedling cultivation is completed, the operator pulls the two inclined limit rods 54 to compress the reset spring 55, so that the inclined limit rods 54 no longer limit the connecting plate 51, and then pulls the bent handle 52 to pull out the placement plate 31, the cultivation pot 42 and the seedlings together. The wheel frame 56 can support the placement plate 31 when pulling it out, and then the operator takes the cultivation pot 42 upward to take out the seedlings. After taking out the seedlings, the operator puts the cultivation pot 42 back on the placement plate 31 and then pushes the placement plate 31 to reset.

[0031] Example 2

[0032] On the basis of Example 1, Figure 9-10As shown, a cleaning mechanism is also included, and the cleaning mechanism is arranged on the water supply pipe 59. The cleaning mechanism is used to clean the drip holes on the water supply pipe 59. The cleaning mechanism includes a plurality of side plates 701, two of the side plates 701 form a group, and each group of the side plates 701 is respectively fixedly connected to three of the water supply pipes 59. A sliding long rod 71 is slidably connected between the two side plates 701 of each group, and a tension spring 72 is connected between the sliding long rod 71 and the side plate 701. A plurality of rings 73 are slidably connected to each of the water supply pipes 59, and the rings 73 are connected to the sliding long rod 71. Each of the sliding long rods 71 ​​is close to the diversion pipe 57. One end of each of the water supply pipes 59 is fixedly connected to a baffle rod 74, three push rods 75 are fixedly connected to the placement plate 31, and the push rods 75 are in contact with the baffle rod 74, each of the collars 73 is fixedly connected to a movable rack 76, each of the water supply pipes 59 is fixedly connected to a plurality of support plates 77, each of the support plates 77 is rotatably connected to a curved rod 78, one side of each of the curved rods 78 is fixedly connected to a rotating gear 79, and each of the water supply pipes 59 is slidably connected to a plurality of brush rods 710 on the upper part, and a guide plate 711 is fixedly connected to the upper end of each of the brush rods 710, and a straight groove is opened on the guide plate 711, and one end of the curved rod 78 is located in the straight groove on the guide plate 711.

[0033] At first, the tension spring 72 is in a stretched state. When the operator pulls the placement plate 31 to move horizontally away from the shunt pipe 57, the horizontal movement of the placement plate 31 will drive the push rod 75 to move horizontally away from the shunt pipe 57. After the push rod 75 moves horizontally away from the shunt pipe 57, the tension spring 72 will drive the sliding long rod 71 to move horizontally away from the shunt pipe 57 and reset. The horizontal movement of the sliding long rod 71 will drive the sleeve ring 73 and the moving rack 76 to move horizontally together. The horizontal movement of the moving rack 76 will drive the curved rod 78 to rotate one circle by rotating the gear 79. The rotation of the curved rod 78 will drive the guide plate 711 and the brush rod 710 to move downward first and then reset upward. The downward movement of the brush rod 710 will pass through the square hole on the adjusting ring 69 and through the drip hole at the bottom of the water supply pipe 59. In this way, the drip hole at the bottom of the water supply pipe 59 and the round hole on the adjusting ring 69 can be cleaned, so that the drip hole at the bottom of the water supply pipe 59 is not easily blocked, thereby ensuring water supply.

[0034] Example 3

[0035] On the basis of Example 2, Fig.11As shown, it also includes a top frame mechanism, which is arranged on the connecting plate 51. The top frame mechanism is used to lift up the supporting frame 41. The top frame mechanism includes two limit blocks 81. The two limit blocks 81 are fixedly connected to the connecting plate 51. A pushing frame 82 is slidably connected between the two limit blocks 81. A plurality of inclined blocks 83 are fixedly connected to the pushing frame 82. Two small round rods 84 are fixedly connected to each of the supporting frames 41. Two positioning rods 85 are fixedly connected to the side of the pushing frame 82 away from the connecting plate 51. A return spring 86 is connected between the two positioning rods 85 and the placing plate 31.

[0036] When the operator pulls out the placement plate 31 and the cultivated seedlings together, the operator can push the pushing frame 82 to move horizontally a distance toward the direction close to the shunt pipe 57. The horizontal movement of the pushing frame 82 will drive the positioning rod 85 to move horizontally together, the return spring 86 is compressed, and then the horizontal movement of the pushing frame 82 will drive the inclined block 83 to move horizontally a certain distance together. The inclined block 83 moves horizontally a distance toward the direction close to the shunt pipe 57, which will squeeze the small round rod 84 to move upward for a distance. The upward movement of the small round rod 84 will drive the support frame 41 and the cultivation pot 42 to move upward for a distance. Since the cultivation of seedlings takes a long time, the cultivation pot 42 for placing the seedlings may adhere to the placement plate 31 due to the soil in the environment and other reasons over time, making it difficult for the cultivation pot 42 to be taken out. The small round rod 84 is lifted up by the inclined block 83, thereby driving the cultivation pot 42 and the support frame 41 to move upward for a distance, which can make the cultivation pot 42 easier to take out.
