[0002] Vegetables are an essential part of people's daily diet, providing the human body with a variety of essential vitamins, minerals and other nutrients. In modern cities, residents can use spaces such as balconies to grow vegetables and other plants.

[0003] To make full use of limited space and grow more vegetables, many people use planting racks. Planting racks can reduce the floor space required for vegetable planting and instead occupy more vertical space. Planting racks allow vegetables to be planted in layers at different heights. However, different crop types and different growth stages require different vertical spaces. However, existing planting racks are not convenient for adjusting the height spacing between different layers of vegetables, which can easily lead to problems such as insufficient spacing affecting crop growth or excessive spacing causing space waste and other unreasonable space utilization.

[0004] Therefore, this utility model provides an adjustable planting rack for vegetable cultivation. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4As shown, an adjustable planting rack for vegetable cultivation according to an embodiment of this utility model includes a base 1; a first set of connecting rods 14 is rotatably connected to the top of the base 1; a middle crossbar 12 is rotatably connected to the top of the first set of connecting rods 14; a second set of connecting rods 14 is rotatably connected to the top of the middle crossbar 12; a top crossbar 13 is rotatably connected to the top of the second set of connecting rods 14; a longitudinal plate 15 is fixedly connected to the top of the end of the base 1; the end of the top crossbar 13 is slidably connected to the middle of the longitudinal plate 15; a slider 16 is slidably connected to the middle of the longitudinal plate 15; a lead screw 18 is rotatably connected to the middle of the slider 16; a crank 17 is fixedly connected to the end of the lead screw 18; the end of the lead screw 18 and the end of the middle crossbar 12 are threadedly engaged; planting soil bearing components are installed on both sides of the base 1, the middle crossbar 12, and the top crossbar 13; during operation, planting soil bearing components are used to support the planting soil. The components are installed on both sides of the base 1, the middle crossbar 12, and the top crossbar 13. When it is necessary to adjust the distance between multiple layers of crops, the crank 17 can be turned to drive the lead screw 18 to rotate. Through the threaded engagement between the lead screw 18 and the middle crossbar 12, the middle crossbar 12 moves towards or away from the longitudinal plate 15. During the movement of the middle crossbar 12, the two sets of connecting rods 14 will rotate synchronously. At the same time, the heights of the middle crossbar 12 and the top crossbar 13 will change accordingly to adjust the height spacing of different layers of crops. The height of the slider 16 will slide and rise synchronously along the longitudinal plate 15 with the middle crossbar 12. Through the above structure, the planted crops can be divided into multiple layers, and the height spacing of each layer of crops can be easily adjusted to adapt to the planting of different crops at different times, thereby improving the rational utilization of space.

[0025] like Figures 1 to 5As shown, the planting soil support assembly includes a water collection tray 2, a planting tray 21, a cotton pad 22, and cotton strips 23. The water collection tray 2 is installed on both sides of the base 1, the middle crossbar 12, and the top crossbar 13. The planting tray 21 is detachably installed on the top of the water collection tray 2. The cotton pad 22 is detachably installed on the inner bottom of the planting tray 21. Multiple cotton strips 23 are provided and fixed to the bottom of the cotton pad 22, and the cotton pad 22 is set through the bottom of the planting tray 21. When the crop is difficult to care for for a period of time, the owner can inject some water into the water collection tray 2, and then install the planting tray 21 on the water collection tray 2. At this time, multiple cotton strips 23 will fall into the water in the water collection tray 2, while the planting soil is located above the cotton pad 22, which fully replenishes the water in the planting soil. When the owner leaves and the planting soil is not adequately watered, the moisture in the planting soil will gradually evaporate and be absorbed by the crops. Meanwhile, the cotton strip 23 will absorb the water from the water collection tray 2 and wet the cotton pad 22. When the moisture content of the planting soil is lower than that of the cotton pad 22, the water in the cotton pad 22 will be absorbed by the planting soil, thus allowing the planting soil to maintain a certain level of moisture for a longer period of time until the water in the water collection tray 2 is also depleted. Through the above structure, the planting soil can maintain a moist state for a longer period of time when the crop planting soil is not adequately watered, so that the crops can survive for a longer period of time before entering a state of water shortage, reducing the occurrence of crops withering due to water shortage when the owner is away.

[0026] like Figures 1 to 5 As shown, an elastic tape 3 is fixed to the side wall of the water collection tray 2; a hinged plate 31 is rotatably connected to the middle of the water collection tray 2; the middle of the elastic tape 3 is fixed to the side wall of the hinged plate 31; when the planting tray 21 is filled with planting soil and the planting soil contains a certain amount of moisture, the planting tray 21 will have a high weight, making it inconvenient to remove the planting tray 21 to add water to the inside of the water collection tray 2. At this time, the hinged plate 31 can be pulled to open the tray, and then water can be added to the planting tray 2 through the opening. After adding water to the water collection tray 2, release the opening and closing plate 31. At this time, the opening and closing plate 31 will rotate under the elastic force of the elastic tape 3 and block the gap in the water collection tray 2. The water in the water collection tray 2 with the gap blocked is not easily exposed to direct sunlight, thereby reducing the evaporation rate of the water and allowing the water to be fully used to replenish the soil. With the above structure, the water in the water collection tray 2 can be conveniently replenished without removing the planting tray 21, improving the ease of use of the device.

[0027] like Figures 1 to 5As shown, support strips 4 are fixed to both sides of the base 1, the middle crossbar 12, and the top crossbar 13; multiple slots 41 are opened in the middle of the support strips 4; a pair of insert rods 42 are fixed to the side wall of the water collection tray 2; after some crops grow to a certain extent, their branches and leaves exposed outside the soil become developed, and the space they occupy increases. In order to reduce the competition for space by crops on adjacent planting trays 21, the water collection tray 2 can be moved and the insert rods 42 on the moved water collection tray 2 can be inserted into the corresponding slots 41 to complete the adjustment of the position of some water collection trays 2, so that the distance between adjacent water collection trays 2 changes, thereby reducing the competition for growth space by adjacent crops. Through the above structure, the interval of multiple planting trays 21 can be easily adjusted, thereby facilitating a more rational use of crop growth space.

[0028] like Figures 1 to 4 As shown, an elastic membrane sleeve 5 is fixedly connected to the side wall of the slider 16; the other end of the elastic membrane sleeve 5 is fixedly connected to the middle of the middle crossbar 12; a sleeve 51 is fixedly connected to the middle of the middle crossbar 12; the lead screw 18 is located inside the elastic membrane sleeve 5 and the sleeve 51; during operation, when the position of the middle crossbar 12 is adjusted by rotating the lead screw 18, the elastic membrane sleeve 5 will extend and retract accordingly. The extended and retracted elastic membrane sleeve 5, together with the sleeve 51, will protect the lead screw 18 inside, making it difficult for external soil and other impurities to fall onto the lead screw 18. Through the above structure, the occurrence of soil and other impurities falling onto the lead screw 18, which would obstruct the cooperation between the middle crossbar 12 and the lead screw 18 and affect the movement of the middle crossbar 12, can be reduced.

[0029] like Figures 1 to 4 As shown, a baffle 6 is slidably connected to the middle of the crossbar 12; one end of the baffle 6 is fixed to the side wall of the slider 16; multiple metal rings 61 are fixed to the middle of the elastic diaphragm sleeve 5; when the elastic diaphragm sleeve 5 contracts, the middle of the elastic diaphragm sleeve 5 will droop. At this time, the drooping part will be blocked by the baffle 6 and will be difficult to directly contact the lead screw 18, so as to prevent the elastic diaphragm sleeve 5 from being worn by the rotating lead screw 18. Due to the setting of the metal rings 61, when the middle of the elastic diaphragm sleeve 5 droops, the metal rings 61 will replace part of the elastic diaphragm sleeve 5 and contact and rub against the baffle 6, thereby further reducing the wear of the elastic diaphragm sleeve 5. Through the above structure, the situation where the elastic diaphragm sleeve 5 is damaged by friction and the protective effect on the lead screw 18 is reduced.

[0030] like Figure 4 As shown, multiple first rollers 7 are rotatably connected to the middle of the slider 16; multiple second rollers 71 are rotatably connected to the middle of the top crossbar 13. Through the above structure, the sliding friction between the longitudinal plate 15 and the slider 16 and the top crossbar 13 can be transformed into rolling friction. By reducing the friction, the rotation operation of the crank 17 is more effortless, and the wear of the components is reduced, thus improving the service life of the components.

[0031] During operation, the planting soil support assembly, loaded with planting soil, is installed on both sides of the base 1, the middle crossbar 12, and the top crossbar 13. When it is necessary to adjust the distance between multiple layers of crops, the crank 17 can be turned to drive the lead screw 18 to rotate. Through the threaded engagement between the lead screw 18 and the middle crossbar 12, the middle crossbar 12 moves towards or away from the longitudinal plate 15. During the movement of the middle crossbar 12, the two sets of connecting rods 14 will rotate synchronously, and the heights of the middle crossbar 12 and the top crossbar 13 will change accordingly to adjust the height spacing of different layers of crops. The height of the slider 16 will slide and rise synchronously along the longitudinal plate 15 with the middle crossbar 12. When the crops are difficult to care for for a period of time... When the owner is not in use, they can fill the water collection tray 2 with some water, and then place the planting tray 21 on top of the water collection tray 2. At this time, multiple cotton strips 23 will fall into the water in the water collection tray 2, while the planting soil is located above the cotton pad 22, which fully replenishes the water in the planting soil. After the owner leaves and the planting soil is not fully replenished, the water in the planting soil will gradually evaporate and be absorbed by the crop. The cotton strips 23 will absorb the water in the water collection tray 2 and wet the cotton pad 22. When the moisture content of the planting soil is lower than that of the cotton pad 22, the water in the cotton pad 22 will be absorbed by the planting soil, thus allowing the planting soil to maintain a certain level of moisture for a longer period of time, until the water in the water collection tray 2 is also completely consumed. When the planting tray 21 is full of planting soil and the planting soil contains water... When the soil is moist, the planting tray 21 becomes quite heavy, making it difficult to remove and add water to the water collection tray 2. In this case, the opening and closing plate 31 can be pulled open, and water can be added to the planting tray 21 through the opening. After watering, the opening and closing plate 31 is released. It will then rotate under the elasticity of the elastic tape 3, blocking the opening in the water collection tray 2. The blocked opening prevents direct sunlight from reaching the water in the collection tray 2, thus slowing down evaporation and allowing the water to be used effectively for soil hydration. As some crops grow to a certain size, their exposed branches and leaves become more developed, occupying more space. To reduce space encroachment by crops on adjacent planting trays 21, the trays can be moved... The water collection tray 2 is moved so that the insert rod 42 on the water collection tray 2 is inserted into the corresponding slot 41, thereby adjusting the position of part of the water collection tray 2 and changing the distance between adjacent water collection trays 2 to reduce the competition for growth space by adjacent crops. When the position of the middle crossbar 12 is adjusted by rotating the screw 18, the elastic film sleeve 5 will extend and retract accordingly. The extending and retracting elastic film sleeve 5, together with the sleeve 51, will protect the internal screw 18, making it difficult for external soil and other impurities to fall on the screw 18. When the elastic film sleeve 5 retracts, the middle part of the elastic film sleeve 5 will droop. At this time, the drooping part will be blocked by the baffle 6 and will not be able to directly contact the screw 18, so as to prevent the elastic film sleeve 5 from being worn by the rotating screw 18. Due to the setting of the metal ring 61,When the elastic diaphragm sleeve 5 droops in the middle, the metal ring 61 will replace part of the elastic diaphragm sleeve 5, contacting and rubbing against the baffle 6, thereby further reducing the wear on the elastic diaphragm sleeve 5.
