The number of stoppers 201f is two, one end of each is fixed to the top of the fixing rod 201a, and the other end of each is fixed to one side of the plug-in block 201b.

[0030] The fixing rod 201a is used to support the plug-in block 201b, and the stop block 201f is used to block the plug-in block 201b, so that the plug-in block 201b can only move in one direction. After placing the root of the chili pepper in the placing tray 105, when the chili pepper grows, the root will expand. At this time, the root will squeeze the clamping plate 202k, causing the clamping plate 202k to move. The movement of the clamping plate 202k drives the moving plate 201e to move, and the moving plate 201e drives the fixed ring 201d to rotate. The fixed ring 201d drives the plug-in block 201b to move. Through the movement of the plug-in block 201b, the fertilizer inside the storage frame 102 can be moved to the placing tray 105, thus completing the fertilization of the root of the chili pepper. It only needs to add fertilizer to the inside of the storage frame 102, and there is no need for manual frequent fertilization operations.

[0031] Specifically, the swinging assembly 300 is arranged on one side of the plug-in block 201b and includes a swinging member 301, which includes a connecting rod 301a, a hinged rod 301b, and a swinging plate 301c.

[0042] The placement shaft 202g is used to support the placement block 202h. When the splint 202k is squeezed at the root of the chili pepper, the splint 202k will move, and the movement of the splint 202k will squeeze the torsion spring 202i. The force of the torsion spring 202i can prevent the placement block 202h from shifting.

[0043] Specifically, two splints 202k are provided on the top of the placement block 202h, and both are arranged on the top of the placement block 202h.

[0044] The placement block 202h is used to support the splint 202k. As the chili pepper grows gradually, the root of the chili pepper will squeeze the splint 202k, causing the splint 202k to move.

[0045] Embodiment 3

[0046] Refer to Figures 4 - 5 , which is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, four support shafts 302a are provided at the bottom of the swing plate 301c, and all are arranged at the bottom of the swing plate 301c. A support block 302b is sleeved outside the support shaft 302a, and eight support blocks 302b are provided at the bottom of the swing plate 301c. The support shaft 302a slides on the inner wall of the chute 301b-1.

[0048] When the chili pepper grows gradually, it will squeeze the splint 202k. The splint 202k drives the moving plate 201e to move, the moving plate 201e drives the fixed ring 201d to rotate, the fixed ring 201d drives the connecting rod 301a to rotate, the connecting rod 301a drives the articulated rod 301b to rotate. The movement of the articulated rod 301b drives the support shaft 302a at the bottom of the swing plate 301c to slide on the inner wall of the chute 301b-1. When the support shaft 302a slides to one end of the chute 301b-1, at this time the support shaft 302a drives the swing plate 301c to lift. The movement of the swing plate 301c can move the fertilizer in the storage box 102 to the placement tray 105, thus completing the fertilization of the roots of the chili pepper.

[0049] Specifically, two inclined grooves 301c-1 are provided on the top of the swing plate 301c, and both are arranged on the top of the swing plate 301c.

[0050] The inclined groove 301c-1 is used to concentrate the fertilizer in one place. Through the setting of the inclined groove 301c-1, the fertilizer on the swing plate 301c can be guided, so that the fertilizer particles can accurately move into the placement tray 105, preventing the fertilizer from spreading to both sides when the swing plate 301c moves.

[0051] Specifically, it further includes a main body component 100, which includes a fertilizer pack main body 101, a storage box 102, and a guide plate 103. The number of storage boxes 102 is two, both of which are arranged on one side of the fertilizer pack main body 101. A swing plate 301c is arranged on the inner wall of the storage box 102. The fertilizer pack main body 101 is arranged on one side of the storage box 102. A support frame 104 is arranged on the inner wall of the fertilizer pack main body 101. A support frame 202b is arranged on the inner wall of the support frame 104. The number of guide plates 103 is four, all of which are arranged on one side of the storage box 102.

[0052] The fertilizer pack main body 101 can increase the water retention, air permeability, and fertilizer retention of the soil, providing a good growth environment for plant roots. The storage box 102 is used to provide timely fertilizers for crops. The guide plate 103 is used to guide the fertilizer particles flowing out of the swing plate 301c to prevent the fertilizer from flowing to other places. The support frame 104 is used to protect the support frame 202b.

[0053] Specifically, a placement tray 105 is arranged at the top of the support frame 104, and the rotating rod 202f is movably connected to the inner wall of the fertilizer pack main body 101.

[0054] The placement tray 105 is used to place the small peppers. By opening the plug cover and then adding fertilizers into the storage box 102, the small peppers can be fertilized.

[0055] The fixing component 200 and the swing component 300 are two groups, respectively arranged on one side of the fertilizer pack main body 101.

[0056] In use, first open the plug cover, add fertilizer into the storage box 102, then plant the small pepper seedlings on the top of the placement tray 105. Then, as the small peppers gradually grow, the roots of the small peppers will squeeze the two clamping plates 202k. At this time, the clamping plates 202k will move towards each other. The movement of the clamping plates 202k drives the moving plate 201e to move, and the moving plate 201e drives the fixed ring 201d to rotate. The fixed ring 201d drives the insertion block 201b to move. Since the fixed ball 202e is suspended, it can support the insertion block 201b to keep the insertion block 201b in a constant state, so that the clamping plates 202k maintain a vertical state, which is convenient for placing the pepper roots on one side of the clamping plates 202k. At this time, the fixed ring 201d also drives the connecting rod 301a to rotate, and the connecting rod 301a drives the articulated rod 301b to rotate. The movement of the articulated rod 301b drives the support shaft 302a at the bottom of the swing plate 301c to slide on the inner wall of the chute 301b-1. When the support shaft 302a slides to one end of the chute 301b-1, the support shaft 302a drives the swing plate 301c to lift. The movement of the swing plate 301c can move the fertilizer in the storage box 102 into the placement tray 105, thus completing the fertilization of the small pepper roots. As the roots of the small peppers gradually expand, the clamping plates 202k can be continuously squeezed, so that the swing plate 301c continuously moves upward to complete the continuous fertilization of the small peppers.
