Description

Technical Field

[0001] The utility model relates to the technical field of vegetable cultivation, in particular to a cultivation rack for hydroponic vegetables. Background Art

[0002] Hydroponic vegetables refer to vegetables whose roots mostly grow in layers of nutrient solution, and which are provided with water, nutrients, oxygen, etc. by the nutrient solution, which is different from vegetables cultivated in traditional soil cultivation. In the process of hydroponic vegetable cultivation, in order to increase the utilization of space, the cultivation rack is usually set in the form of a multi-layer structure, one is to reduce the space occupied by cultivation and improve the space utilization rate, and the other is to increase the yield of hydroponic vegetables. Chinese patent document CN216722522U discloses a household hydroponic vegetable planting machine, which is provided with multi-layer planting boxes, each layer of which can be used to plant different plants, thereby improving planting diversity; at the same time, it is provided with plant growth lights at the bottom of the hydroponic tray to provide suitable light for plant growth. However, the hydroponic vegetable planter cannot adjust the spacing between the multi-layer planting boxes, and different vegetable plants have different heights. As a result, when planting vegetables of different types and different growth periods, the height of the vegetables is limited by the spacing between the planting boxes, affecting the normal growth of the vegetables. At the same time, the inability to adjust the spacing between the planting boxes will also affect the vegetables' access to natural light (for example, the lower planting box is blocked by the upper planting box, resulting in the lower planting box being unable to obtain natural light). In addition, the hydroponic vegetable planter cannot adjust the height of the planting box. First, it is inconvenient for operators to carry out the sowing, observation, and harvesting of hydroponic vegetables at high altitudes, reducing planting efficiency. Second, it is inconvenient to replace the nutrient solution in the high planting box (the nutrient solution will gradually accumulate too much material that is hindering plant growth during use, leading to nutritional imbalance, massive reproduction of pathogens, and other problems), resulting in obstructed root growth and even plant death. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a cultivation rack for hydroponic vegetables, which can not only adjust the distance between each layer to avoid the influence of natural light between each layer and ensure that each layer is suitable for the cultivation of different vegetables; but also complete the adjustment of the height of the hydroponic tray, which is convenient for operators to sow, observe, harvest and replace nutrient solution of high-level hydroponic trays, improve planting efficiency and avoid the problem of large-scale withering or death of plants.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A cultivation rack for hydroponic vegetables comprises a base, a support rod, a top plate, a slide plate, a hydroponic tray, a fixed block, a slider and a connecting rod, wherein two groups of support rods are evenly arranged on both sides of the end surface of the base, and the top ends of the support rods are fixedly connected to the same top plate; two slide plates are slidably arranged between the base and the top plate and located outside the two groups of support rods, and four parallel hydroponic trays are arranged between the two slide plates, and the two ends of the hydroponic trays are respectively penetrated by the corresponding side support rods and slidably connected; fixed blocks are fixedly arranged on the inner sides of the two slide plates corresponding to the two groups of hydroponic trays on the lower side, and the sides of the fixed blocks close to the hydroponic trays are connected to the corresponding side walls of the hydroponic trays through connecting rods, and the two ends of the connecting rods are rotatably connected to the corresponding fixed blocks and the hydroponic trays; sliders are slidably arranged on the two slide plates corresponding to the two groups of hydroponic trays on the upper side, and the sides of the sliders close to the hydroponic trays are connected to the corresponding side walls of the hydroponic trays through connecting rods, and the two ends of the connecting rods are rotatably connected to the corresponding sliders and the hydroponic trays.

[0006] Based on the further optimization of the above scheme, a cultivation groove is opened in the middle of the hydroponic tray for storing nutrient solution and placing hydroponic vegetable planting pots.

[0007] In order to ensure the stability of the hydroponic tray support, based on further optimization of the above solution, the fixed block or slider is provided with no less than two connecting rods on one side of the same hydroponic tray, thereby ensuring the stability of the connection between the fixed block or slider and the hydroponic tray.

[0008] Based on further optimization of the above scheme, the cross-section of the slider is an "I"-shaped structure, and a vertical sliding groove is opened on the slide plate corresponding to the slider. The slider is clamped in the vertical sliding groove and slidably connected, so as to realize the vertical sliding of the slider on the slide plate and limit the sliding of the slider.

[0009] Based on the further optimization of the above scheme, the slider controls its up and down movement through a driving mechanism, and the driving mechanism includes a screw, a slide bar and a telescopic rod. There are two screws, which are respectively arranged on the side of the slider away from each other, and the upper and lower ends of the screws are rotatably connected to the bottom surface of the top plate and the end surface of the base respectively; the outer wall of the screw is threadedly sleeved with the slide bar and the two slide bars have the same height in the vertical direction, the slide bar is close to one side of the slider and the telescopic rod is arranged corresponding to the slider, the slider is away from the side of the hydroponic tray and a sliding groove is opened corresponding to the telescopic rod, and the telescopic rod is slidably engaged in the corresponding sliding groove.

[0010] Based on further optimization of the above solution, limit rings are fixedly arranged on the outer walls of the upper and lower ends of the screw thread segment, respectively, for limiting the upward and downward sliding of the slide bar, thereby preventing the slide bar from detaching from the thread segment and causing driving failure.

[0011] The following are the technical effects of the utility model:

[0012] The present application realizes the movement of the two groups of cultivation trays on the lower side and the two groups of cultivation trays on the upper side away from or towards each other through the cooperation of the slide plate, the fixed block, the slider and the connecting rod, so that when the slide plates move in the direction of super approaching or moving away from each other, the two groups of cultivation trays on the lower side and the two groups of cultivation trays on the upper side move away from or towards each other, thereby realizing the adjustment of the spacing between adjacent cultivation trays, avoiding the cultivation trays from blocking each other and affecting the absorption of natural light by hydroponic vegetables. At the same time, by adjusting the spacing between adjacent cultivation trays, it can adapt to hydroponic vegetables of different varieties and different growth cycles, thereby avoiding the restriction of the cultivation trays on the growth height of hydroponic vegetables. At the same time, the present application realizes the overall height adjustment of the two groups of cultivation trays on the upper side through the sliding setting between the slider and the slide plate, so as to facilitate the operator to perform operations such as sowing, observation, harvesting and nutrient solution replacement on the upper cultivation tray, thereby improving the convenience of hydroponic vegetable planting and avoiding problems such as withering or death of hydroponic vegetables due to untimely operation.

[0026] Working principle:

[0027] When it is necessary to adjust the spacing between the hydroponic trays 50 to meet the growth height of different plants or to ensure that the plants on each hydroponic tray 50 can fully obtain natural light, the two slide plates 40 are started to move in a direction close to or away from each other, so that the slide plates 40 respectively drive the fixed block 60 and the slider 70 thereon to follow its movement (when the slider 70 slides, the connection between the slider 72 and the corresponding slider 70 is achieved by sliding the telescopic rod 73 in the sliding groove 710, that is, the vertical position of the slider 70 is fixed during the left and right sliding process), and then the corresponding hydroponic tray 50 is pulled to move through the connecting rod 80; for example: when the two slide plates 40 move in a direction close to each other, the fixed block 60 and the slider 70 respectively push the corresponding adjacent hydroponic trays 50 (that is, the two groups of hydroponic trays 50 on the lower side and the two groups of hydroponic trays 50 on the upper side) through the connecting rod 80 to move in a direction away from each other, thereby increasing the spacing between adjacent hydroponic trays 50 (such as Figure 1 As shown in FIG. 1 ); when the two slide plates 40 move away from each other, the fixed block 60 and the slider 70 pull the corresponding adjacent hydroponic trays 50 (i.e., the two groups of hydroponic trays 50 on the lower side and the two groups of hydroponic trays 50 on the upper side) toward each other through the connecting rod 80, thereby reducing the distance between the adjacent hydroponic trays 50 (as shown in FIG. 1 ). Figure 3 When it is necessary to adjust the height of the two groups of hydroponic trays 50 on the upper side, so as to facilitate the observation, harvesting, nutrient solution replacement and other operations on the top hydroponic tray 50, the screw 71 is started (the screw 71 can be driven to rotate by a motor arranged in the base 10 or the top plate 30), so that it drives the slide bar 72 to move downward, and the slide bar 72 drives the two groups of hydroponic trays 50 on the upper side to move downward through the sliding of the telescopic rod 73 and the slider 70, so as to achieve the height adjustment of the upper hydroponic tray 50.
