[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown in the figure, this utility model provides a multi-layer three-dimensional planting rack for medicinal herbs to prevent diseases and pests, comprising: Planting rack 1; Insect-proof mechanism 2: Insect-proof mechanism 2 is installed on the surface of planting rack 1, and insect-proof mechanism 2 includes: Insect-proof netting 21: The lower surface of insect-proof netting 21 is fixedly connected to the surface of planting rack 1; Insect-attracting lamp 22: Two insect-attracting lamps 22 are provided, and both insect-attracting lamps 22 are set on the outer surface of the planting rack 1; Support plate 23: The support plate 23 is set on the upper side of the insect-attracting lamp 22; Transmission block 24: The right surface of transmission block 24 is fixedly connected to the outer surface of support plate 23; Threaded rod 25: The outer surface of threaded rod 25 is rotatably connected to the inside of transmission block 24 by threads, and the outer surface of threaded rod 25 is rotatably connected to the inner wall of planting frame 1 by bearings; Servo motor 26: The output end of servo motor 26 is fixedly connected to the upper end face of threaded rod 25, and the lower surface of servo motor 26 is fixedly connected to the upper surface of planting frame 1.

[0018] refer to Figure 1 As shown, a first groove 3 is provided on the right surface of the planting rack 1, and the inner wall of the first groove 3 is slidably connected to the outer surface of the transmission block 24.

[0019] The above solution is adopted: the servo motor 26 drives the threaded rod 25 to rotate, and the threaded rod 25 drives the transmission block 24 to move longitudinally along the inner wall of the first slide groove 3 through the thread. The transmission block 24 then drives the insect-attracting lamp 22 to move longitudinally back and forth on the outer surface of the planting rack 1 through the support plate 23, thereby improving the insect control efficiency.

[0020] refer to Figure 4 As shown, the insect-attracting lamp 22 is provided with a clamping component 4 on its upper side. There are two clamping components 4, and the two clamping components 4 include: Clamping plate 41: Four clamping plates 41 are provided, and the outer surfaces of the four clamping plates 41 are in contact with the outer surface of the insect-attracting lamp 22. Second slide 42: There are four second slides 42, and the inner walls of the four second slides 42 are slidably connected to the upper end of the clamping plate 41.

[0021] The above solution is adopted: In order to install the insect-attracting lamp 22 on the support plate 23, the insect-attracting lamp 22 is placed between four clamping plates 41, and then the four clamping plates 41 are moved together along the inner wall of the second sliding groove 42 toward the insect-attracting lamp 22 until the outer surface of the clamping plate 41 is in contact with the outer surface of the insect-attracting lamp 22, thereby fixing the insect-attracting lamp 22 on the underside of the support plate 23.

[0022] refer to Figure 4 As shown, a travel assembly 5 is provided on the upper surface of the clamping plate 41. There are two travel assemblies 5, each including: Stroke pins 51: There are four stroke pins 51, and the lower end faces of the four stroke pins 51 are fixedly connected to the upper surface of the clamping plate 41; Stroke plate 52: Stroke plate 52 is located inside support plate 23; Stroke groove 53: There are four stroke grooves 53, which are formed on the surface of the stroke plate 52. The inner wall of the stroke groove 53 is slidably connected to the outer surface of the stroke column 51. Drive component 54: The lower end face of drive component 54 is fixedly connected to the upper surface of stroke disk 52, and the outer surface of drive component 54 is rotatably connected to the upper surface of support plate 23 through bearing.

[0023] Using the above solution: In order to move the clamping plate 41 closer to the inward side, the drive member 54 is rotated. The drive member 54 can drive the travel plate 52 to rotate, so that the travel plate 52 drives the travel groove 53 on the surface to move in a circle. The inner wall of the travel groove 53 presses against the outer surface of the travel column 51, so that the travel column 51 slides along the inner wall of the travel groove 53. At the same time, the travel column 51 can drive the clamping plate 41 to move closer to the insect-attracting lamp 22 along the inner wall of the second slide groove 42, thereby achieving the function of driving the clamping plate 41.

[0024] refer to Figure 4 As shown, a clamping assembly 6 is provided on the outer surface of the driving component 54. There are two clamping assemblies 6, and the two clamping assemblies 6 include: Clamping groove 61: Clamping groove 61 is formed on the upper surface of support plate 23; Clamping component 62: The lower end face of clamping component 62 is in contact with the inner wall of clamping groove 61, and clamping component 62 penetrates the inner wall of driving component 54; First tension spring 63: The first tension spring 63 is sleeved on the outer surface of the clamping member 62, the lower end face of the first tension spring 63 is fixedly connected to the upper surface of the driving member 54, and the upper end face of the first tension spring 63 is fixedly connected to the lower surface of the clamping member 62.

[0025] The above solution is adopted as follows: In order to make the driving component 54 rotate, the clamping component 62 is pulled upward. The clamping component 62 can pull the first tension spring 63, so that the first tension spring 63 generates elastic force until the clamping component 62 leaves the inside of the clamping groove 61. Only then can the driving component 54 rotate. When the clamping component 62 corresponds to the clamping groove 61, the first tension spring 63 releases its tension, pulling the clamping component 62 into the inside of the clamping groove 61. At this time, the driving component 54 is fixed and cannot rotate, thus indirectly fixing the clamping plate 41.

[0026] refer to Figure 3 As shown, the surface of the insect-proof net 21 is provided with a sliding component 7, which includes: Third groove 71: The third groove 71 is formed on the surface of the planting rack 1; Slider 72: There are two sliders 72. The outer surfaces of the two sliders 72 are slidably connected to the inner wall of the third groove 71. The lower surface of the sliders 72 is fixedly connected to the upper surface of the insect net 21. Connecting ring 73: The outer surface of connecting ring 73 is fixedly connected to the outer surface of slider 72, and the lower surface of connecting ring 73 is fixedly connected to the upper surface of insect net 21.

[0027] Using the above solution: In order to retract the insect net 21, the connecting ring 73 is pulled down, so that the connecting ring 73 moves downward along the inner wall of the third slide groove 71 via the slider 72, and the connecting ring 73 drives the insect net 21 to retract upward.

[0028] refer to Figure 3 As shown, a locking component 8 is provided on the surface of the slider 72. The locking component 8 includes: Slot 81: Slot 81 is provided on the left surface of the planting rack 1; Positioning component 82: Positioning component 82 passes through the inside of the left slider 72, the outer surface of positioning component 82 is slidably connected to the inside of slider 72, and the right end face of positioning component 82 is in contact with the inner wall of positioning groove 81. Second tension spring 83: The second tension spring 83 is sleeved on the outer surface of the locking member 82, the left end face of the second tension spring 83 is fixedly connected to the right surface of the locking member 82, and the right end face of the second tension spring 83 is fixedly connected to the left surface of the slider 72.

[0029] Using the above solution: In order for the slider 72 to move downward, the locking member 82 is pulled outward, which in turn pulls the second tension spring 83, causing the second tension spring 83 to generate tension until the locking member 82 is no longer in contact with the locking groove 81, only then can the slider 72 move downward.

[0030] The working principle of this utility model: In use, by pulling the connecting ring 73 upward, the connecting ring 73 moves upward along the inner wall of the third slide groove 71 via the slider 72. The connecting ring 73 then moves the insect-proof net 21 upward, so that the insect-proof net 21 covers the planting rack 1 from all sides until the locking piece 82 corresponds to the locking groove 81. The second tension spring 83 can release the tension, pull the locking piece 82 into the locking groove 81, and fix the insect-proof net 21. Then, by placing the insect-attracting lamp 22 between the four clamping plates 41, and pulling the clamping member 62 upward, the clamping member 62 can pull the first tension spring 63, causing the first tension spring 63 to generate elastic force until the clamping member 62 leaves the inside of the clamping groove 61. Only then can the drive member 54 be rotated, which can drive the travel plate 52 to rotate, causing the travel plate 52 to drive the travel groove 53 on its surface to move circumferentially. The inner wall of the travel groove 53 presses against the outer surface of the travel column 51, causing the travel column 51 to move along the travel groove. The inner wall of 53 slides, and at the same time, the stroke column 51 can drive the clamping plate 41 to move closer to the insect-attracting lamp 22 along the inner wall of the second slide groove 42 until the outer surface of the clamping plate 41 and the outer surface of the insect-attracting lamp 22 are in contact with each other. At the same time, the clamping member 62 corresponds to the clamping groove 61, the first tension spring 63 releases the tension, pulls the clamping member 62 into the clamping groove 61, the driving member 54 is fixed and cannot rotate, and the clamping plate 41 is indirectly fixed, and the insect-attracting lamp 22 is fixedly installed on the lower side of the support plate 23. Finally, the servo motor 26 drives the threaded rod 25 to rotate. The threaded rod 25 drives the transmission block 24 to move longitudinally along the inner wall of the first slide groove 3 through the thread. The transmission block 24 then drives the insect-attracting lamp 22 to move longitudinally on the outer surface of the planting rack 1 through the support plate 23. When the transmission block 24 moves to one end, the servo motor 26 rotates in the opposite direction, causing the insect-attracting lamp 22 to move in the other direction. This cycle repeats, improving the insect control efficiency.

[0031] In summary, this multi-layered three-dimensional planting rack for medicinal herbs, through its insect-proof mechanism 2, first sliding groove 3, clamping component 4, travel component 5, clamping component 6, sliding component 7, and positioning component 8, solves the problems of insufficient pest and disease control, which easily leads to the rapid spread of pests and diseases, resulting in reduced yield and deterioration of medicinal herbs. It also increases the cost of pesticide use and manual management, shortens the lifespan of the planting rack, and may affect the safety of medicinal herbs due to pesticide residues.
