[0013] 2. The present invention causes the planting frame to slide downward and drives the fixed bar to move downward. The downward movement of the fixed bar drives the connecting rod to swing, thereby causing the push rod to move and push the push plate to slide. The heavier the vegetables in the planting frame, the longer the distance the planting frame slides downward, the greater the swing amplitude of the connecting rod, and the farther the slider slides. As a result, when the push plate squeezes the telescopic rod of the cylinder, the pressure in the cylinder will increase, and the amount of culture water sprayed from the water outlet of the water tank will increase. Therefore, different doses of culture water can be sprayed in time according to the weight of the vegetables in the planting frame, so that the vegetables and the culture soil can maintain the required moisture and nutrition, avoid spraying too much or too little culture water, which is beneficial to the growth of vegetables, thereby effectively improving the quality of vegetables.

[0014] 3. The present invention sprays culture water through a plurality of water spray holes on the water pipe, thereby evenly irrigating the vegetables in the planting frame so that the vegetables can grow evenly. In addition, according to the number of cultivated vegetables, the knob can be twisted to drive the water retaining pipe to rotate. The rotation of the water retaining pipe can block part of the water spray holes of the water outlet pipe, so that the culture water can only be sprayed from the other water spray holes of the water inlet pipe. This can reduce a large amount of waste of culture water, prevent excessive watering of culture water from diluting the nutrients in the culture soil, and cause poor growth of vegetables, thereby more effectively improving the quality of vegetables.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Embodiment 1: A lifting and circulating vegetable cultivation device, such as Figure 1-Figure 7As shown, it includes a bracket 1, and four wheels are provided at the bottom of the bracket 1. The four wheels on the bracket 1 are used to facilitate the staff to push the bracket 1. A motor 2 is connected to one side of the lower part of the bracket 1 by bolts, and a transmission rod 3 is connected to the output shaft of the motor 2 by bolts. The transmission rod 3 is horizontally arranged, and the transmission rod 3 is rotatably connected to the bracket 1. Two transmission gears 4 are connected to the transmission rod 3 by a flat key, and four transmission gears 4 are also rotatably connected to both sides of the inner wall of the bracket 1. Five transmission gears 4 form a group, and the two groups of transmission gears 4 are symmetrically arranged. A chain 5 is wound between the five transmission gears 4 in each group, and the five transmission gears 4 are all meshed with the chain 5. A water collecting box 1001 is placed at the bottom of the inner wall of the bracket 1, and a lifting component is provided on the chain 5. The lifting component is used to automatically circulate the vegetables for illumination. A water replenishment component is provided on the bracket 1, and the water replenishment component is connected to the lifting component. The water replenishment component is used to automatically irrigate the vegetables with culture water.

[0028] The lifting assembly includes a suspension rod 61, and a plurality of suspension rods 61 are welded on the two chains 5. The two suspension rods 61 form a group, and a bracket 62 is placed between the two suspension rods 61 in each group. The number of the brackets 62 is five, and each of the brackets 62 is slidably connected to a planting frame 63, and the planting frame 63 is used for planting vegetables. A plurality of return springs 64 are connected to the bottom of the planting frame 63 and the bracket 62 through hooks. A limiting plate 65 is connected to one side of the outer wall of each planting frame 63 through rivets, and a limiting rod 66 is slidably connected to each bracket 62. Each limiting rod 66 is horizontally arranged, and a top plate 67 is connected to the lower part of the inner wall of the bracket 1 through rivets, and the top plate 67 is located between two of the transmission gears 4.

[0029] Each planting frame 63 has an air hole at the bottom.

[0030] The water replenishment assembly includes a water tank 71, which is connected to the top of the bracket 1 by bolts. The water tank 71 is provided with a water inlet and a water outlet. A fixing rod 72 is welded to the upper part of the bracket 1. One end of the fixing rod 72 is connected to a cylinder 73 by bolts. The cylinder 73 is located below the water tank 71. A rotating rod 731 is fixedly connected to the telescopic rod of the cylinder 73. A return spring 74 is connected between the rotating rod 731 and the cylinder 73. The return spring 74 is sleeved on the rotating rod 731. On the telescopic rod of the cylinder 73, an air injection pipe 75 is connected between the cylinder 73 and the water tank 71, the other end of the fixed rod 72 is connected to a guide plate 76 by bolts, and the guide plate 76 is vertically arranged, each of the brackets 62 is connected to a guide block 77 by bolts, and each of the brackets 62 is slidably connected to a push plate 78 at the bottom, and a compression spring 79 is connected between the push plate 78 and the bracket 62 by a hook, and the compression spring 79 is sleeved on the push plate 78.

[0031] At first, the water tank 71 is filled with culture water, and the first planting frame 63 is located below the water outlet of the water tank 71. In actual application, the staff first pours the culture soil into the five planting frames 63 in turn, and then plants the vegetables on the culture soil in turn, and pushes the bracket 1 to move to the sunlight. Then the staff starts the motor 2, and the output shaft of the motor 2 rotates to drive the transmission rod 3 to rotate. The rotation of the transmission rod 3 will drive two of the transmission gears 4 to rotate, and the rotation of two of the transmission gears 4 will drive the two chains 5 to rotate. The rotation of the two chains 5 will drive the other transmission gears 4 to rotate. The rotation of the two chains 5 will drive several suspension rods 61 to move back and forth up and down, and the up and down reciprocating movement of several suspension rods 61 will drive five brackets 62 to move back and forth up and down. The five brackets 62 move up and down. The reciprocating movement will drive the five planting frames 63 to move up and down, so that the vegetables in the five planting frames 63 can receive light evenly for photosynthesis. The downward movement of the first planting frame 63 will drive the guide block 77 and the push plate 78 to move downward together. The guide block 77 will contact the guide plate 76 when it moves downward and get stuck in the guide plate 76. The guide plate 76 will guide the guide block 77, so that the downward movement of the planting frame 63 is more stable. The push plate 78 will contact the rotating rod 731 when it moves downward, and squeeze the rotating rod 731 to move. The movement of the rotating rod 731 will push the telescopic rod of the cylinder 73 to contract, and the return spring 74 will be compressed. The contraction of the telescopic rod of the cylinder 73 will cause gas to be injected into the water tank 71 from the gas injection pipe 75, thereby squeezing the culture water spray in the water tank 71. The water is sprinkled in the planting frame 63 to supplement the nutrients and water for the vegetables in the planting frame 63. The push plate 78 continues to move downward and will be out of contact with the rotating rod 731. The reset of the return spring 74 will drive the rotating rod 731 to reset. The reset of the rotating rod 731 will drive the telescopic rod of the cylinder 73 to extend and reset. The water tank 71 will no longer spray the culture water. Then the next planting frame 63 will move to the bottom of the water outlet of the water tank 71. Repeating this process can timely irrigate the vegetables with culture water to avoid the vegetables from withering and dying, effectively improving the survival rate of the vegetables. At the same time, the weight of the vegetables, culture soil and culture water will cause the planting frame 63 to slide downward, the reset spring 64 will be compressed, the planting frame 63 will slide downward and drive the limit plate 65 to slide downward, and the bracket 62 will drive the limit rod 65 to move up and down while reciprocating. 6 moves up and down, the limit rod 66 moves downward and contacts with the top plate 67, the top plate 67 will squeeze the limit rod 66 to slide, the limit rod 66 slides and contacts with the limit plate 65, and is stuck in the limit plate 65, so as to stabilize the planting frame 63 and prevent the planting frame 63 from shaking during the up and down reciprocating movement. In the process of watering the culture water, the excess culture water will flow into the water collecting box 1001 below. When the vegetables are grown, the staff turns off the motor 2, cleans the culture water in the water collecting box 1001, then removes the five brackets 62, cuts the vegetables in the planting frame 63, cleans the culture soil in the planting frame 63, and after cleaning, hangs the bracket 62 back on the suspension rod 61. After the planting frame 63 loses the weight of the culture soil and vegetables,The reset spring 64 resets the planting frame 63 and the limit plate 65, and the limit plate 65 resets to squeeze the limit rod 66 to slide and reset, and then disengages from the limit rod 66.

[0032] Embodiment 2: Based on embodiment 1, Figure 6-Figure 8 As shown, it also includes a quantity control component, which is arranged on the bracket 62. The quantity control component is used to control the dosage of the culture water sprayed, and the quantity control component includes a slide rail 81. The five slide rails 81 are respectively connected to the bottom upper side surfaces of the five brackets 62 by bolts, and each of the slide rails 81 is slidably connected to a slider 82. A fixing bar 83 is welded to the bottom of each planting frame 63, and a connecting rod 84 is rotatably connected between the fixing bar 83 and the slider 82. Each of the sliders 82 is connected to a push rod 85 by bolts, and the push rod 85 is in contact with the push plate 78.

[0033] At first, the staff will pour different amounts of culture soil into the planting frame according to the number of vegetables to be planted. When the planting frame 63 slides downward, it will drive the fixing bar 83 to move downward. The downward movement of the fixing bar 83 will drive the connecting rod 84 to swing. The swing of the connecting rod 84 will drive the slider 82 to slide. The sliding of the slider 82 will drive the push rod 85 to move. The movement of the push rod 85 will push the push plate 78 to slide, and the compression spring 79 will be stretched. The heavier the weight of the vegetables in the planting frame 63 and the longer the distance the planting frame 63 slides downward, the greater the swing of the connecting rod 84 and the farther the slider 82 slides, which will squeeze the push plate 78. When the telescopic rod of the air cylinder 73 is compressed, the pressure in the air cylinder 73 will increase, and the dosage of the culture water sprayed from the water outlet of the water tank 71 will increase, so that different dosages of culture water can be automatically sprayed according to the weight of the vegetables in the planting frame 63, so that the vegetables and the culture soil can maintain the required moisture and nutrients, avoiding excessive or insufficient dosage of culture water sprayed, which is beneficial to the growth of vegetables, thereby effectively improving the quality of vegetables. The planting frame 63 slides upward and resets, which will drive the fixed bar 83, the connecting rod 84, the slider 82 and the push rod 85 to reset. The push rod 85 resets and no longer pushes the push plate 78. The compression spring 79 resets and drives the push plate 78 to slide and reset.

[0034] Embodiment 3: Based on embodiment 2, Figure 7-Figure 9As shown, it also includes an adjusting component, which is arranged on the bracket 1. The adjusting component is used to evenly spray the culture water and adjust the spraying size. The adjusting component includes a water outlet pipe 91, which is connected to the upper inner wall of the bracket 1 by bolts. The water outlet pipe 91 is horizontally arranged, and a plurality of water spray holes are opened on the water outlet pipe 91. The plurality of water spray holes on the water outlet pipe 91 are used to spray the culture water. The water outlet pipe 91 is connected to the water outlet of the water tank 71, and one end of the water outlet pipe 91 is connected to a threaded rod 92 by bolts. A water retaining pipe 93 is rotatably connected to the water outlet pipe 91, and one end of the water retaining pipe 93 is connected to a knob 94 by a rivet, and the knob 94 is threadedly connected to the threaded rod 92.

[0035] The staff can adjust the amount of water for irrigation according to the number of vegetables in the planting frame 63. If there are more vegetables in the planting frame 63, there is no need to twist the knob 94. The culture water in the water tank 71 will first flow into the water outlet pipe 91, and then be sprayed on the vegetables in the planting frame 63 through a number of water spray holes on the water outlet pipe 91, so that the vegetables in the planting frame 63 can be evenly irrigated so that the vegetables can grow evenly. If there are fewer vegetables in the planting frame 63, turn the knob 94. The rotation of the knob 94 will drive the water retaining pipe 93 to rotate. The rotation of the water retaining pipe 93 can block some of the water spray holes of the water outlet pipe 91, so that the culture water can only be sprayed from the other water spray holes of the water inlet pipe, which can reduce a large amount of waste of culture water, prevent excessive watering of the culture water from diluting the nutrients in the culture soil, and cause poor growth of vegetables, thereby more effectively improving the quality of vegetables.

[0036] Embodiment 4: Based on the embodiment 3, Figure 1-Figure 10 As shown, it also includes a porous ventilation tube 11, and five of the porous ventilation tubes 11 are respectively connected to the inner walls of the five planting frames 63 by bolts. Each of the porous ventilation tubes 11 is provided with a filter, and the filter on the porous ventilation tube 11 is used to make the culture soil breathable.

[0037] At first, when the staff puts the culture soil into the planting frame 63, the culture soil will cover the filter holes of the porous ventilation tube 11, and the oxygen in the air will enter the porous ventilation tube 11, and then provide oxygen to the culture soil through the filter holes of the porous ventilation tube 11, and also make the soil breathable, thereby improving the air permeability of the culture soil and promoting the growth of vegetables.
