[0001] The present invention relates to the technical field of Codonopsis pilosula seedling cultivation, and specifically provides a liquid fertilizer spraying device for garden planting. Background Art

[0002] Codonopsis pilosula seedling cultivation mainly propagates by sowing. Select high-quality seeds, soak them for 24 hours, and then sow them in loose and well-drained soil. The sowing depth is about 1 - 2 cm, cover with a thin layer of soil to keep it moist, maintain the temperature between 15 - 25 °C, and keep the humidity appropriate to ensure the germination of seeds. During the seedling stage, it is necessary to regularly weed, fertilize, and prevent and control pests and diseases. After 6 - 8 months, it can be transplanted to the field. Codonopsis pilosula likes a shady and humid environment, and should be shaded during cultivation to ensure good root growth.

[0003] Chinese Patent with Patent Publication No. CN218649465U discloses a seedling cultivation device for Codonopsis pilosula planting, including a seedling cultivation box, a soil moisture sensor, and a ventilation fan. The inner walls on both sides of the seedling cultivation box are fixedly connected with placing plates at equal intervals, and cultivation boxes are arranged on the tops of the placing plates. A controller is arranged on one side surface of the seedling cultivation box. A wire is connected to the bottom of the controller, and the end of the wire is connected to a soil moisture sensor, and the soil moisture sensor is located inside the cultivation box. A water tank is arranged on one side surface of the seedling cultivation box. Through the installation of a cultivation box, a controller, a soil moisture sensor, a water tank, a water pump, a water delivery pipe, and a nozzle, an automatic water replenishment structure is provided, which can timely spray and irrigate Codonopsis pilosula seedlings when it is detected that the planting soil is short of water, so as to avoid staff constantly paying attention to the seedling conditions, ensure the normal growth of Codonopsis pilosula seedlings, and effectively solve the problems and deficiencies in the existing device.

[0004] However, the current seedling cultivation device has the following problems: When cultivating Codonopsis pilosula seedlings with this device, if too much liquid fertilizer is irrigated to Codonopsis pilosula, personnel cannot timely drain the excess liquid fertilizer from the cultivation box. The excessive liquid fertilizer will cause oxygen deficiency in the roots of Codonopsis pilosula, affect the root respiration of Codonopsis pilosula, and further inhibit the growth of the roots of Codonopsis pilosula, thereby causing root rot of Codonopsis pilosula. Therefore, we propose a liquid fertilizer spraying device for garden planting. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a liquid fertilizer spraying device for garden planting, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A garden planting liquid fertilizer spraying device includes a storage box. A bracket is fixed to the bottom of the storage box. A spraying system is arranged outside the storage box. An anti-waterlogging device is arranged inside the storage box. The anti-waterlogging device includes a cultivation box, a motor, two U-shaped telescopic handles, and two fixed sleeves. The cultivation box is vertically slidably installed inside the storage box. The telescopic ends of the two U-shaped telescopic handles are respectively fixed to both sides of the cultivation box. The two fixed sleeves are respectively fixed to both sides of the storage box. The fixed sleeves are used to fix the fixed ends of the U-shaped telescopic handles to both sides of the storage box. A rotating rod is rotatably installed inside the storage box. Two cams are fixed to both outer sides of the rotating rod. The motor is fixed to the outer wall of the storage box. The rotating rod is fixed to the output end of the motor. The outer wall of the cam is in contact with the bottom of the cultivation box. A plurality of strip-shaped grooves are opened at the bottom of the inner wall of the cultivation box. By driving the rotating rod to rotate through the motor, the rotating rod drives the cam to rotate. The cam pushes the cultivation box to move upward. The cultivation box drives the telescopic ends of the U-shaped telescopic handles to move upward. When the cam does not push the cultivation box, under the elastic force of the U-shaped telescopic handle, the telescopic end of the U-shaped telescopic handle drives the cultivation box to reset and move downward. In this way, the cultivation box reciprocates up and down, so that the cultivation box shakes up and down reciprocally.

[0007] According to the above technical solution, the anti-waterlogging device further includes a plurality of square rods. The plurality of square rods are evenly and equidistantly fixed to the bottom of the inner wall of the storage box, and the plurality of square rods all pass through the strip-shaped grooves of the cultivation box. Oblique elastic rods are fixed to both sides of the top of the square rod. The connection point of the oblique elastic rod and the square rod is a flexible connection. A notch is opened on the side of the oblique elastic rod close to the square rod. The notch of the oblique elastic rod is arranged in the direction towards the slider. The arrangement of the notch of the oblique elastic rod increases the contact area between the oblique elastic rod and the cultivated soil, thereby facilitating the oblique elastic rod to loosen the cultivated soil. A slider is slidably installed on the outer wall below the square rod, and a spring is arranged between the slider and the bottom of the inner wall of the storage box. The top of the slider is in contact with the bottom of the cultivation box. Hinged rods are respectively hinged to both outer sides of the slider. The ends of the two hinged rods away from the slider are respectively hinged to the inner wall of the oblique elastic rod. Each time the cultivation box moves upward, under the elastic force of the corresponding spring received by the slider, the slider will always abut against the bottom of the cultivation box, and the slider will move upward along the outside of the square rod. The slider pushes the hinged rod to drive the oblique elastic rod to swing upward slightly, so that the oblique elastic rod loosens the cultivated soil in the cultivation box.

[0008] According to the above technical solution, the spraying system includes a right-angle frame, a water divider, a connecting pipe, a water pump, and a fertilizer storage tray. The right-angle frame is fixed to the side wall of the storage box. The water divider is fixed to the top of the right-angle frame. The fertilizer storage tray is fixed to the inner wall of the bracket. The water pump is fixed to the bottom of the inner wall of the fertilizer storage tray. The top end of the connecting pipe is fixed to the outer wall of the water divider, and the bottom end of the connecting pipe is fixed to the water outlet end of the water pump. When liquid fertilizer needs to be applied to Codonopsis pilosula, the water pump is started. The water pump extracts the liquid fertilizer in the fertilizer storage tray and transports it to the water divider through the connecting pipe. The water divider will sprinkle the liquid fertilizer on the Codonopsis pilosula, thereby realizing the operation of applying liquid fertilizer to Codonopsis pilosula.

[0009] According to the above technical solution, an air venting device is provided between every two adjacent sliders. The air venting device includes a long air pipe, a plurality of fixing plates, a plurality of folding bags, a plurality of one-way air inlet nozzles, and a plurality of one-way air outlet nozzles. The plurality of fixing plates are respectively fixed between two adjacent sliders. The long air pipe is fixed to the top of the plurality of fixing plates. The plurality of one-way air outlet nozzles are evenly and equidistantly fixed to the top of the long air pipe. The plurality of folding bags are respectively fixed to the bottom of the plurality of fixing plates, and the bottoms of the plurality of folding bags are fixedly connected to the bottom of the inner wall of the storage box. The plurality of one-way air inlet nozzles are respectively fixed to the bottoms of the plurality of folding bags, and the plurality of one-way air inlet nozzles penetrate through the bottom of the inner wall of the storage box. The inside of the long air pipe is in communication with the inside of the folding bags. The one-way air inlet nozzles are used to control the one-way air intake of the folding bags, and the one-way air outlet nozzles are used to control the one-way air outlet of the folding bags. Each time the telescopic end of the U-shaped telescopic handle drives the cultivation box to reset and move downward, the cultivation box will press the slider to move downward along the outer wall of the square rod. The slider drives the fixing plate to squeeze the folding bag. The air in the folding bag is discharged from the one-way air outlet nozzle through the long air pipe. The one-way air outlet nozzle will inject air into the nutrient soil in the cultivation box.

[0010] According to the above technical solution, a medicine spraying device is provided at the square rod. The medicine spraying device includes a medicine storage tank, a transmission pipe, a spray head, an L-shaped convex block rod, and a pressing member. The medicine storage tank is fixed on the top of the storage box. The transmission pipe is fixed on the top of the medicine storage tank. The transmission pipe penetrates through the bottom of the square rod. The spray head is fixed on the top of the transmission pipe. The L-shaped convex block rod is fixed on the outer wall of the slider and penetrates through the bottom of the inner wall of the storage box. The pressing member is fixed on the side wall of the medicine storage tank. A semi-circular convex block is fixed on the outer wall of the L-shaped convex block rod near the medicine storage tank on the lower side. The pressing end of the pressing member is semi-circularly arranged. The semi-circular pressing end of the pressing member is located on the movement track of the semi-circular convex block of the L-shaped convex block rod. Each time when medicine needs to be sprayed on the codonopsis pilosula, the liquid medicine is injected into the medicine storage tank. Each time the slider moves upward, the slider drives the L-shaped convex block rod to move upward. When the semi-circular convex block of the L-shaped convex block rod moves to the position of the semi-circular pressing end of the pressing member, the semi-circular convex block of the L-shaped convex block rod pushes the semi-circular pressing end of the pressing member to squeeze the pressing end of the pressing member. The pressing member controls the liquid medicine in the medicine storage tank to be sprayed out from the spray head through the transmission pipe, thereby completing the medicine spraying operation on the codonopsis pilosula.

[0011] A cultivation method of a liquid fertilizer spraying device for garden planting includes the following steps:

[0012] S1. Place the cultivation box into the storage box, and at this time, the U-shaped telescopic handle is placed on both sides of the storage box;

[0013] S2. Fix the fixed end of the U-shaped telescopic handle on the outer wall of the storage box through the fixing sleeve;

[0014] S3. Pour the cultivation soil into the cultivation box, and then the codonopsis pilosula can be sown and propagated;

[0015] S4. When the codonopsis pilosula needs to be watered with liquid fertilizer, start the water pump. The water pump extracts the liquid fertilizer in the fertilizer storage tray and transmits it to the water distributor through the connecting pipe. The water distributor will sprinkle the liquid fertilizer on the codonopsis pilosula, thereby realizing the operation of watering the codonopsis pilosula with liquid fertilizer;

[0016] S5. If too much liquid fertilizer is irrigated on the codonopsis pilosula, drive the rotating rod to rotate through the motor. The rotating rod drives the cam to rotate. The cam pushes the cultivation box to move upward. The cultivation box drives the telescopic end of the U-shaped telescopic handle to move upward. When the cam does not push the cultivation box, under the elastic force of the U-shaped telescopic handle, the telescopic end of the U-shaped telescopic handle drives the cultivation box to reset and move downward. In this way, the cultivation box reciprocates up and down. The reciprocation can help the liquid fertilizer penetrate more evenly into each layer of the soil;

[0017] S6. At the same time, the excess liquid fertilizer can flow into the storage box through the strip-shaped groove of the cultivation box.

[0018] The present invention provides a liquid fertilizer spraying device and method for gardening, which has the following beneficial effects:

[0019] (1) The present invention sets a water accumulation prevention device so that the motor, the rotating rod, the cam, the cultivation box, and the U-shaped telescopic handle cooperate to drive the cultivation box to shake back and forth up and down. The shaking can help the liquid fertilizer to penetrate into each layer of the soil more evenly, avoid the accumulation of liquid fertilizer in a certain position to cause waterlogging at the root, and ensure that the root system of Codonopsis pilosula has a suitable moist environment. At the same time, the excess liquid fertilizer can flow into the storage box through the strip groove of the cultivation box, thereby achieving the purpose of discharging the excess liquid fertilizer from the cultivation box; at the same time, the cultivation box, the slider, the square rod, and the hinged rod cooperate to drive the oblique elastic rod to loosen the culture soil in the cultivation box, so that the oblique elastic rod breaks the compaction of the culture soil, so that the gaps between the culture soil particles are increased, which helps to improve the air permeability of the soil, avoid waterlogging in the culture soil and hypoxia of Codonopsis pilosula caused by excessive liquid fertilizer, and after the culture soil is loosened, the liquid fertilizer can penetrate into the deep soil layer more evenly and quickly, avoid the accumulation of liquid fertilizer on the surface, thereby reducing the influence of waterlogging on the root of Codonopsis pilosula.

[0020] (2) The present invention sets a ventilation device so that the U-shaped telescopic handle, the cultivation box, the slider, the square rod, the slider, and the fixed plate cooperate to squeeze the folding bag. The air in the folding bag is discharged from the one-way air outlet through the long air tube. The one-way air outlet injects the air into the nutrient soil in the cultivation box. After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula requires sufficient oxygen for breathing and metabolic activities. When there is too much liquid fertilizer, the oxygen in the nutrient soil will be consumed, forming an oxygen-deficient environment, which will further affect the growth of the root system. The injection of air can effectively prevent root hypoxia and improve the health and growth rate of the root system.

[0021] (3) The present invention arranges a spraying device so that the slider, the L-shaped protrusion rod, and the pressing piece cooperate to control the liquid medicine in the medicine storage box to be sprayed out from the spray head through the transmission pipe, thereby completing the spraying operation of Codonopsis pilosula. In this process, the cultivation box is shaken up and down. The shaking can promote the contact between the liquid medicine and the culture soil particles, enhance the diffusion speed of the liquid medicine in the culture soil, and make the effective ingredients more easily penetrate into the culture soil, thereby providing effective protection for the root system of Codonopsis pilosula and preventing and controlling underground diseases and pests.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Please refer to Figure 1 - Figure 7 , one embodiment of the present invention is: a liquid fertilizer spraying device for garden planting, including a storage box 1, a bracket 2 is fixed at the bottom of the storage box 1, a spraying system 3 is arranged outside the storage box 1, and a water accumulation prevention device 4 is arranged inside the storage box 1. The water accumulation prevention device 4 includes a cultivation box 41, a motor 46, two U-shaped telescopic handles 42, and two fixed sleeves 43. The cultivation box 41 is vertically slidably installed inside the storage box 1, and the telescopic ends of the two U-shaped telescopic handles 42 are respectively fixed on both sides of the cultivation box 41 (in combination with Figure 1 and Figure 3) Two fixing sleeves 43 are respectively fixed on both sides of the storage box 1. The fixing sleeves 43 are used to fix the fixed ends of the U-shaped telescopic handle 42 on both sides of the storage box 1. A rotating rod 44 is rotatably installed inside the storage box 1. Cam 45s are fixed on both outer sides of the rotating rod 44. The motor 46 is fixed on the outer wall of the storage box 1. The rotating rod 44 is fixed on the output end of the motor 46. The outer wall of the cam 45 is in contact with the bottom of the cultivation box 41. A plurality of strip-shaped grooves are opened at the bottom of the inner wall of the cultivation box 41. Through the setting of the above structure, the cultivation box 41 shakes up and down. The shaking can help the liquid fertilizer penetrate more evenly into each layer of the soil, avoid the accumulation of liquid fertilizer at a certain position causing waterlogging of the roots, ensure that the root system of the Codonopsis pilosula has a suitable moist environment, and at the same time, the excess liquid fertilizer can flow into the storage box 1 through the strip-shaped grooves of the cultivation box 41, so as to achieve the purpose of discharging the excess liquid fertilizer from the cultivation box 41.

[0032] The water accumulation prevention device 4 further includes a plurality of square rods 47. The plurality of square rods 47 are evenly and equidistantly fixed on the bottom of the inner wall of the storage box 1, and the plurality of square rods 47 all pass through the strip-shaped grooves of the cultivation box 41. Oblique elastic rods 48 are fixed on both sides of the top of the square rod 47. The connection point of the oblique elastic rod 48 and the square rod 47 is a flexible connection. A notch is opened on the side of the oblique elastic rod 48 close to the square rod 47. The notch of the oblique elastic rod 48 is arranged in the direction towards the slider 49 (as Figure 4 shown). The setting of the notch of the oblique elastic rod 48 increases the contact area between the oblique elastic rod 48 and the cultivated soil, so as to facilitate the oblique elastic rod 48 to loosen the cultivated soil. A slider 49 is slidably installed on the outer wall below the square rod 47, and a spring is provided between the slider 49 and the bottom of the inner wall of the storage box 1. The pressure exerted on the slider 49 by the soil and the storage box 1 is less than the restoring force of the spring corresponding to the slider 49. The top of the slider 49 is in contact with the bottom of the cultivation box 41. Hinge rods 410 are hinged on both outer walls of the slider 49. The two ends of the two hinge rods 410 away from the slider 49 are respectively hinged on the inner wall of the oblique elastic rod 48. Through the setting of the above structure, the oblique elastic rod 48 loosens the cultivated soil in the cultivation box 41, so that the oblique elastic rod 48 breaks the hardening of the cultivated soil, increases the gaps between the cultivated soil particles, helps to improve the air permeability of the soil, avoids the phenomenon of water accumulation in the cultivated soil and oxygen deficiency of the Codonopsis pilosula caused by excessive liquid fertilizer, and after the cultivated soil is loosened, the liquid fertilizer can penetrate more evenly and quickly into the deep layer of the soil, avoiding the accumulation of liquid fertilizer on the surface layer, thereby reducing the influence of waterlogging on the roots of the Codonopsis pilosula.

[0033] The spraying system 3 includes a right-angle frame 31, a water divider 32, a connecting pipe 33, a water pump 34, and a fertilizer storage tray 35. The right-angle frame 31 is fixed to the side wall of the storage box 1, the water divider 32 is fixed to the top of the right-angle frame 31, the fertilizer storage tray 35 is fixed to the inner wall of the bracket 2, the water pump 34 is fixed to the bottom of the inner wall of the fertilizer storage tray 35, the top end of the connecting pipe 33 is fixed to the outer wall of the water divider 32, and the bottom end of the connecting pipe 33 is fixed to the water outlet end of the water pump 34. When the Codonopsis pilosula needs to be watered with liquid fertilizer, the water pump 34 is started, and the water pump 34 extracts the liquid fertilizer in the fertilizer storage tray 35 and transmits it to the water divider 32 through the connecting pipe 33. The water divider 32 will sprinkle the liquid fertilizer on the Codonopsis pilosula, thereby realizing the liquid fertilizer watering operation of the Codonopsis pilosula.

[0034] A ventilation device 5 is provided between two adjacent sliders 49, and the ventilation device 5 includes a long air pipe 54, a plurality of fixed plates 51, a plurality of folding bags 52, a plurality of one-way air inlet nozzles 53, and a plurality of one-way air outlet nozzles 55. The plurality of fixed plates 51 are respectively fixed between two adjacent sliders 49, the long air pipe 54 is fixed to the top of the plurality of fixed plates 51, a plurality of one-way air outlet nozzles 55 are evenly and equidistantly fixed to the top of the long air pipe 54, a plurality of folding bags 52 are respectively fixed to the bottom of the plurality of fixed plates 51, and the bottoms of the plurality of folding bags 52 are fixedly connected to the bottom of the inner wall of the storage box 1, a plurality of one-way air inlet nozzles 53 are respectively fixed to the bottom of the plurality of folding bags 52, and the plurality of one-way air inlet nozzles 53 penetrate the bottom of the inner wall of the storage box 1, and the long air pipe 5 The interior of 4 is interconnected with the interior of the folding bag 52, the one-way air inlet nozzle 53 is used to control the one-way air inlet of the folding bag 52, and the one-way air outlet nozzle 55 is used to control the one-way air outlet of the folding bag 52. Through the arrangement of the above structure, the air in the folding bag 52 is discharged from the one-way air outlet nozzle 55 through the long air pipe 54, and the one-way air outlet nozzle 55 will inject air into the nutrient soil in the cultivation box 41. After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula needs sufficient oxygen for breathing and metabolic activities. In the case of too much liquid fertilizer, the oxygen in the nutrient soil will be exhausted, forming an oxygen-deficient environment, which will further affect the growth of the root system. Through the injection of air, the root hypoxia can be effectively prevented, and the health and growth rate of the root system can be improved.

[0035] During use, place the cultivation box 41 into the storage box 1. At this time, the U-shaped telescopic handle 42 is placed on both sides of the storage box 1. Fix the fixed end of the U-shaped telescopic handle 42 to the outer wall of the storage box 1 through the fixing sleeve 43. Pour the cultivation soil into the cultivation box 41, and then the codonopsis can be sown and propagated. When the codonopsis needs to be watered, when the codonopsis needs to be watered with liquid fertilizer, start the water pump 34. The water pump 34 pumps the liquid fertilizer in the fertilizer storage tray 35 and transmits it to the water distributor 32 through the connecting pipe 33. The water distributor 32 will sprinkle the liquid fertilizer on the codonopsis, thus realizing the operation of watering the codonopsis with liquid fertilizer. If too much liquid fertilizer is irrigated to the codonopsis, drive the rotating rod 44 to rotate through the motor 46. The rotating rod 44 drives the cam 45 to rotate. The cam 45 pushes the cultivation box 41 to move upward. The cultivation box 41 drives the telescopic end of the U-shaped telescopic handle 42 to move upward. When the cam 45 does not push the cultivation box 41, under the elastic force of the U-shaped telescopic handle 42, the telescopic end of the U-shaped telescopic handle 42 drives the cultivation box 41 to reset and move downward. This reciprocates, so that the cultivation box 41 reciprocates up and down. The shaking can help the liquid fertilizer penetrate more evenly into each layer of the soil, avoid the accumulation of liquid fertilizer in a certain position causing waterlogging of the roots, and ensure that the roots of the codonopsis have a suitable moist environment. At the same time, the excess liquid fertilizer can flow into the storage box 1 through the strip-shaped groove of the cultivation box 41, so as to achieve the purpose of discharging the excess liquid fertilizer from the cultivation box 41; every time the cultivation box 41 moves upward, under the action of the elastic force of the corresponding spring on the slider 49, the slider 49 will always abut against the bottom of the cultivation box 41, and the slider 49 will move upward along the outside of the square rod 47. The slider 49 pushes the articulated rod 410 to drive the inclined elastic rod 48 to swing slightly upward, so that the inclined elastic rod 48 loosens the cultivation soil in the cultivation box 41, so that the inclined elastic rod 48 breaks the soil compaction, increases the gaps between the cultivation soil particles, helps to improve the air permeability of the soil, avoids the phenomenon of waterlogging of the cultivation soil and hypoxia of the codonopsis caused by too much liquid fertilizer, and after the cultivation soil is loosened, the liquid fertilizer can penetrate more evenly and quickly into the deep layer of the soil, avoiding the accumulation of liquid fertilizer on the surface layer, so as to reduce the influence of waterlogging on the roots of the codonopsis.

[0036] Each time the telescopic end of the U-shaped telescopic handle 42 drives the cultivation box 41 to reset and move downward, the cultivation box 41 presses the slider 49 to move downward along the outer wall of the square rod 47. The slider 49 drives the fixing plate 51 to squeeze the folding bladder 52. The air in the folding bladder 52 is discharged from the one-way air outlet nozzle 55 through the long air pipe 54. The one-way air outlet nozzle 55 injects air into the nutrient soil in the cultivation box 41. After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula needs sufficient oxygen for respiration and metabolic activities. Excessive liquid fertilizer will cause the oxygen in the nutrient soil to be exhausted, forming an oxygen-deficient environment, which will affect the growth of the root system. By injecting air, root hypoxia can be effectively prevented, and the health and growth rate of the root system can be improved; each time the slider 49 moves upward along the outside of the square rod 47, the slider 49 stretches the folding bladder 52 through the fixing plate 51. At this time, the folding bladder 52 intakes air through the one-way air inlet nozzle 53, thus completing the replenishment of the internal air of the folding bladder 52.

[0037] Please refer to Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, a medicine spraying device 6 is provided at the square rod 47. The medicine spraying device 6 includes a medicine storage box 61, a transmission pipe 62, a spray head 63, an L-shaped convex block rod 64, and a pressing member 65. The medicine storage box 61 is fixed on the top of the storage box 1. The transmission pipe 62 is fixed on the top of the medicine storage box 61. The transmission pipe 62 penetrates through the bottom of the square rod 47. The spray head 63 is fixed on the top of the transmission pipe 62. The L-shaped convex block rod 64 is fixed on the outer wall of the slider 49, and the L-shaped convex block rod 64 penetrates through the bottom of the inner wall of the storage box 1. The pressing member 65 is fixed on the side wall of the medicine storage box 61. It should be noted that the working principle of the pressing member 65 here is similar to that of a spray bottle. The pressing member 65 is composed of a pressing part and a spring pump, so as to achieve reset through the elastic force of the spring pump. A semi-circular convex block is fixed on the outer wall of the lower side of the L-shaped convex block rod 64 near the medicine storage box 61. The pressing end of the pressing member 65 is semicircularly arranged. The semicircular pressing end of the pressing member 65 is located on the movement track of the semi-circular convex block of the L-shaped convex block rod 64. Through the above structural settings, the pressing member 65 controls the liquid medicine in the medicine storage box 61 to be sprayed out from the spray head 63 through the transmission pipe 62, thus completing the medicine spraying operation of Codonopsis pilosula. And during this process, the cultivation box 41 shakes up and down. The shaking can promote the contact between the liquid medicine and the culture soil particles, enhance the diffusion speed of the liquid medicine in the culture soil, and make the medicinal components more easily penetrate into the culture soil, providing effective protection for the root system of Codonopsis pilosula and preventing underground diseases and pests.

[0038] During use, when spraying medicine on Codonopsis pilosula each time, the liquid medicine is injected into the medicine storage box 61. Each time the slider 49 moves upward, the slider 49 drives the L-shaped convex block rod 64 to move upward. When the semi-circular convex block of the L-shaped convex block rod 64 moves to the semi-circular position at the pressing end of the pressing member 65, the semi-circular convex block of the L-shaped convex block rod 64 pushes the semi-circular pressing end of the pressing member 65 to squeeze the pressing end of the pressing member 65. The pressing member 65 controls the liquid medicine in the medicine storage box 61 to be sprayed out from the spray head 63 through the transmission pipe 62, thus completing the spraying operation of Codonopsis pilosula. And during this process, the cultivation box 41 shakes up and down. The shaking can promote the contact between the liquid medicine and the culture soil particles, enhance the diffusion speed of the liquid medicine in the culture soil, make the medicinal components more easily penetrate into the culture soil, provide effective protection for the roots of Codonopsis pilosula, and prevent underground diseases and pests.
