Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plant planting cups, specifically to a height-adjustable planting cup. Background Technology
[0002] Planting cups are tools used for plant cultivation. In the field of leafy vegetable cultivation in modern plant factories, planting cups are an indispensable and important planting tool.
[0003] Currently, the vast majority of planting cups on the market have a fixed height. This fixed height design does not reveal any obvious drawbacks in the early stages of leafy vegetable growth. However, as leafy vegetables grow into their later stages, the problems gradually become apparent, as detailed below:
[0004] In the later stages of leafy vegetable growth, the leaves rapidly enlarge and extend outwards. Because the planting basket is at a fixed height, the outer leaves (especially lettuce) inevitably droop onto the cultivation rack, leading to severely insufficient ventilation at the base of the plant. Good ventilation is crucial for healthy plant growth. In poorly ventilated environments, air cannot circulate effectively around the base of the plant, making it difficult to reduce humidity. High humidity creates a breeding ground for harmful microorganisms. Leaves near the roots and the cultivation board are easily attacked by bacteria, fungi, and other microorganisms due to prolonged exposure to this damp and poorly ventilated environment, leading to rot. Rotten leaves not only affect the quality and yield of individual plants, reducing their commercial value, but can also trigger a chain reaction. Rotten leaves can become a source of disease transmission, spreading pathogens to surrounding plants and causing the disease to spread throughout the entire cultivation area, seriously threatening the production safety of leafy vegetable cultivation. Moreover, in the plant factory model, pesticides are usually not used to deal with problems such as leaf rot in order to ensure the green, healthy and safe quality of vegetables. This makes the problem of leaf rot caused by poor ventilation even more difficult to solve.
[0005] Therefore, there is an urgent need to provide a planting cup whose height can be adjusted to improve ventilation. Utility Model Content

[0046] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0047] The height-adjustable planting cup of this application can be used in occasions where the height of the plant needs to be adjusted, and of course it can also be used in other similar application scenarios. The following is a detailed description of a height-adjustable planting cup.
[0048] Example 1
[0049] See appendix Figure 1 — Figure 5 The diagram shows a preferred embodiment of a height-adjustable planting cup according to this application. The height-adjustable planting cup includes a fixed cup body 1, a lifting cup body 2 movably installed within the fixed cup body 1, and a height adjustment structure 3 disposed on both the fixed cup body 1 and the lifting cup body 2. A support plate 4 is provided at the top of the fixed cup body 1, and a control plate 5 is provided at the top of the lifting cup body 2. An avoidance structure 6 is provided on the support plate 4. The height adjustment structure 3 includes a lifting guide groove 31 disposed on the outer wall of the lifting cup body 2, limiting grooves 32 evenly spaced on the outer wall of the lifting cup body 2 and connected to the lifting guide groove 31, and a limiting member 33 installed on the inner wall of the fixed cup body 1. The lifting guide groove 31 is a straight groove, with its opening direction perpendicular to the horizontal plane.
[0050] It should be noted that the planting cup in this application is for use in plant factories, while in the prior art, planting cups are generally placed on planting boards in plant factories. In this application, the planting cup is divided into a fixed cup body 1 and a lifting cup body 2. The fixed cup body 1 is fixedly installed on the planting board, while the lifting cup body 2 moves up and down along the fixed cup body 1. The height adjustment structure 3 is set on the fixed cup body 1 and the lifting cup body 2. When the height adjustment structure 3 is damaged, only the corresponding fixed cup body 1 or lifting cup body 2 needs to be replaced, without replacing the planting board or other structures, thus reducing replacement costs. In this application, the lifting guide groove 31, the limiting groove 32, and the limiting member 33 are set up. The lifting member 33 and the lifting guide groove 31 cooperate to guide the lifting movement of the lifting cup body 2, ensuring that the limiting member 33 can cooperate with the limiting groove 32 to fix and support the lifting cup body 2.
[0051] See appendix Figure 2 — Figure 4 As shown, in this utility model, the lifting guide groove 31 is a straight groove; the limiting groove 32 is located in the lifting guide groove 31, and the opening direction of the limiting groove 32 is parallel to the horizontal plane, and the limiting groove 32 is an arc-shaped groove.
[0052] This invention features a straight lifting guide groove 31, allowing workers to move the lifting cup 2 vertically by simply pulling it up or down using the control panel 5. A limiting groove 32 is positioned within the lifting guide groove 31, enabling the limiting member 33 to engage with the limiting groove 32 and secure the lifting cup 2 simply by moving it up or down. Furthermore, the limiting groove 32 is designed as an arc-shaped recess, ensuring that the limiting member 33 and the limiting groove 32 can engage or disengage.
[0053] See appendix Figure 2 — Figure 4 As shown, in this utility model, the length of the limiting member 33 is fixed. The limiting member 33 includes a guide portion 338 corresponding to the lifting guide groove 31, and a limiting portion 339 corresponding to the limiting groove 32 disposed on the guide portion 338; wherein the guide portion 338 is spherically shaped.
[0054] This utility model guides the lifting and lowering movement of the lifting cup body 2 by setting the guide part 338 in cooperation with the lifting guide groove 31. It should be noted that the limiting part 339 is set in a protruding shape and cooperates with the limiting groove 32. The limiting part 33 and the limiting groove 32 are made of materials with elastic deformation such as plastic, so that after the limiting part 339 and the limiting groove 32 are engaged, the limiting part 33 can elastically deform and separate from the limiting groove 32 under the application of external force by the operator.
[0055] See appendix Figure 2 — Figure 4As shown, in this utility model, the inner wall of the fixed cup body 1 is parallel to the outer wall of the lifting cup body 2, that is, the minimum straight-line distance between the inner wall of the fixed cup body 1 and the outer wall of the lifting cup body 2 is equal on any cross-section of the fixed cup body 1, so that the distance between the inner wall of the fixed cup body 1 and the outer wall of the lifting cup body 2 remains unchanged throughout the lifting process, thereby ensuring that the fixed-length limiting member 33 can also engage with the corresponding limiting groove 32 after the lifting cup body 2 moves up and down.
[0056] See appendix Figure 2 and Figure 3 As shown, in this utility model, the avoidance structure 6 includes an avoidance groove 61 that is set at equal angles on the top surface of the support plate 4; the bottom of the fixed cup body 1 is provided with a through hole 14, and the side wall of the fixed cup body 1 is provided with a first through waist-shaped hole 15 at equal angles; the bottom of the lifting cup body 2 is provided with a support grid plate 21, and the side wall of the lifting cup body 2 is provided with a second through waist-shaped hole 22 at equal angles.
[0057] This invention provides a clearance groove 61 on the top surface of the support plate 4, which avoids the fingers of the operator when the support plate 4 and the control plate 5 come into contact, making it easier for the operator to apply force to the control plate 5. The through hole 14 is used to avoid the lifting cup body 2, so that the height of the lifting cup body 2 can be greater than the height of the fixed cup body 1. The first through waist-shaped hole 15 and the second through waist-shaped hole 22 ensure that the plant inside the lifting cup body 2 can come into contact with clean water or nutrient solution, ensuring that the plant can grow normally. The support grid plate 21 is used to support the plant, ensuring that the plant can be placed inside the lifting cup body 2.
[0058] Example 2
[0059] See appendix Figure 6 As shown, the difference between this embodiment and the above embodiment is that in this embodiment, the avoidance structure 6 is set on the bottom surface of the control plate 5, that is, multiple avoidance grooves 61 set at equal angles are located on the bottom surface of the control plate 5.
[0060] Example 3
[0061] See appendix Figure 7 — Figure 9 As shown, the difference between this embodiment and the above embodiment is that the guide portion 338 is arranged in a columnar shape in this embodiment.
[0062] In this embodiment, the guide part 338 is set as a column, which enhances the cooperation between the guide part 338 and the lifting guide groove 31, makes the gap between the guide part 338 and the groove wall of the lifting guide groove 31 more uniform, further prevents the lifting guide groove 31 from separating from the guide part 338, and ensures that the limiting part 339 can be engaged with the limiting groove 32 to limit the lifting cup body 2.
[0063] Example 4
[0064] See appendix Figure 10 — Figure 12 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the limiting groove 32 is located beside the lifting guide groove 31, the opening direction of the limiting groove 32 is perpendicular to the horizontal plane, the limiting groove 32 is a straight groove, and the groove width of the limiting groove 32 is equal to the groove width of the lifting guide groove 31; the limiting groove 32 is also provided with a connecting groove 321 for connecting the lifting guide groove 31 and the limiting groove 32, and the opening direction of the connecting groove 321 is parallel to the horizontal plane; between any interconnected connecting groove 321 and limiting groove 32, the straight distance between the top wall of the connecting groove 321 and the bottom surface of the lifting cup body 2 is less than the straight distance between the top wall of the limiting groove 32 and the bottom surface of the lifting cup body 2; the groove depths of the lifting guide groove 31, the limiting groove 32, and the connecting groove 321 are equal; the limiting member 33 is arranged in a columnar shape.
[0065] Compared to the above embodiments, this embodiment connects the limiting groove 32 and the lifting guide groove 31 through the connecting groove 321, and the width and depth of the three grooves are equal, so that the limiting member 33 can be rotated into the limiting groove 32, so that the limiting groove 32 and the limiting member 33 cooperate to limit the movement. Compared with the above embodiments, this embodiment increases the contact area between the limiting groove 32 and the limiting member 33, improves the support strength of the limiting member 33 for the lifting cup body 2, and enables the limiting member 33 to limit the lifting cup body 2 with a heavier total mass. It should be noted that the total mass of the lifting cup body 2 includes the sum of the mass of the lifting cup body 2 itself, the plant, etc.
[0066] Example 5
[0067] See appendix Figure 13 and Figure 14 As shown, the difference between this embodiment and embodiments 1 and 2 above is that, in this embodiment, the lifting guide groove 31 is a spiral groove; it should be noted that the limiting groove 32 is directly connected to the lifting guide groove 31; it should be noted that the limiting groove 32 can be a groove or a straight groove. When the limiting groove 32 is a groove, the limiting member 33 is hemispherical. When the limiting groove 32 is a straight groove, the limiting member 33 is columnar.
[0068] In this embodiment, by setting the lifting guide groove 31 as a spiral groove and extending the length of the lifting guide groove 31, the number of lifting guide grooves 31 connected is increased, which allows for more precise adjustment of the height of the lifting cup body 2.
[0069] Example 6
[0070] See appendix Figure 15 and Figure 16As shown, the difference between this embodiment and embodiment 5 above is that, in this embodiment, the distance between the inner wall of the fixed cup body 1 and the outer wall of the lifting cup body 2 decreases as the minimum distance between the cross-section of the fixed cup body 1 and the bottom surface of the fixed cup body 1 increases; the limiting member 33 is columnar, and the length of the limiting member 33 on any horizontal plane is greater than the minimum distance between the inner wall of the fixed cup body 1 and the outer wall of the lifting cup body 2. It should be noted that, in this embodiment, the lifting cup body 2 is also provided with a disassembly groove 330, the groove direction of which is perpendicular to the horizontal plane and is connected to the lifting guide groove 31.
[0071] This embodiment changes the distance between the outer wall of the lifting cup body 2 and the inner wall of the fixed cup body 1, maximizing the gap between the bottom of the lifting cup body 2 and the fixed cup body 1, making it easier for the lifting cup body 2 to be installed inside the fixed cup body 1. By limiting the length of the limiting member 33, it is ensured that the limiting member 33 can be located within the lifting guide groove 31 throughout the entire process, and the limiting member 33 can cooperate with the limiting groove 32 for limiting. This embodiment separates the lifting cup body 2 from the fixed cup body 1 groove and the lifting guide groove 31 through the setting of the disassembly groove 330, preventing the operator from accidentally separating the lifting cup body 2 from the fixed cup body 1 when adjusting the lifting cup body 2.
[0072] Example 7
[0073] See appendix Figure 17 — Figure 19 As shown, the difference between this embodiment and the above embodiment 6 is that, in this embodiment, the fixed cup body 1 is provided with an installation groove 11, the installation groove 11 is provided with a through hole 12, the installation plate 13 is installed in the installation groove 11, and the limiting member 33 is installed on the installation plate 13; wherein, the limiting member 33 includes a guide post 331 installed on the fixed cup body 1 and located in the through hole 12, a hollow telescopic post 332 slidably installed on the guide post 331, an end cap 333 installed on the hollow telescopic post 332, and an elastic member 334 located in the hollow telescopic post 332. The hollow telescopic post 332 corresponds to the lifting guide groove 31; the guide post 331 is provided with a guide groove 335, the end of the guide groove 335 is provided with a limiting platform 336, the end of the hollow telescopic post 332 away from the end cap 333 is provided with a slider 337 adapted to the guide groove 335, and the elastic member 334 is a spring, one end of the spring is in contact with the end cap 333, and the other end is in contact with the guide post 331.
[0074] In this embodiment, the hollow telescopic column 332 is used to provide installation space for the elastic element 334 and ensure that the hollow telescopic column 332 can cooperate with the guide column 331; the end cap 333 is used to seal one end of the hollow telescopic column 332 and limit one end of the elastic element 334; the guide groove 335 is used to guide the telescopic movement of the hollow telescopic column 332 in conjunction with the slider 337; and the limiting platform 336 is used to limit the movement of the slider 337 and prevent the hollow telescopic column 332 from separating from the guide column 331.
