Description

Technical Field

[0001] The present invention belongs to the technical field of watermelon seedling raising, and particularly relates to a seedling raising and cultivation device for watermelon and melon. Background Art

[0002] Watermelon seedling raising refers to the process of cultivating seedlings by using a seedbed or other suitable environmental conditions through the cultivation and germination of seeds during the planting process. The process of watermelon seedling raising generally includes germination acceleration, transplanting, and fixing the seedlings.

[0003] When the watermelon and melon seedlings grow to about three leaves and one heart, they need to be transplanted. The existing devices generally have three schemes during the germination acceleration stage before transplantation: The first is a whole cultivation plate, and cultivation cavities are fixedly arranged on the cultivation plate. Since the watermelon and melon seedlings need to grow to the stage of three leaves and one heart before transplantation, each cultivation cavity requires a relatively large space. A whole cultivation plate can neither include too many cultivation cavities at one time nor facilitate the operation of shoveling soil for transplantation. It is also rather troublesome to separately take out some plants for observation.

[0004] The second is mutually independent cultivation cavities. For example, a seedling raising rack for agricultural planting shown in the authorized publication number CN114271130B includes a rack body, and carrying plates are arrayed and installed on the rack body. This scheme requires separate operations for each plant, resulting in low efficiency.

[0005] The third is a scheme between the two, splitting a whole cultivation plate into multiple rows of cultivation plates, and multiple cultivation cavities are arranged on each row of cultivation plates. Due to the splitting, each row of cultivation plates is independent. When taking out the cultivation plates, the inner cultivation plates may be located deeper and are difficult to take out.

[0006] Therefore, we propose a seedling raising and cultivation device for watermelon and melon to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to solve the problem in the prior art that separate operations need to be carried out for each plant, resulting in low efficiency, and to propose a seedling raising and cultivation device for watermelon and melon.

[0008] To achieve the above purpose, the present invention adopts the following technical scheme:

[0009] A seedling raising and cultivation device for watermelon and melon includes a box body with one side open. Slide rails are arranged on both sides inside the box body, and a plurality of placement modules are detachably and slidably arranged in the box body through the slide rails;

[0010] The placement module includes a placement rack with a plurality of cultivation cavities penetrating through the top surface. The cultivation cavities are frustum-shaped with a larger upper part and a smaller lower part, and a bottom plate matching with the lower end of the cultivation cavity is arranged at the lower end of the cultivation cavity. A driving component for driving the bottom plates of a plurality of the same placement rack to move up and down is arranged below one end of the slide rail close to the open part of the box body;

[0011] On both upper ends of one side of the placing rack facing the open side of the box body, anti-collision boxes are fixedly connected, and driving rods are rotatably arranged at both lower ends. Cavities are provided at both ends of the placing rack, and a transmission rod and an acceleration assembly for accelerating the transmission of the transmission rod through the driving rod are arranged in the cavities. One end of the transmission rod away from the anti-collision box is fixedly connected with a first magnet, and a second magnet is fixedly connected in the anti-collision box. Adjacent placing modules are magnetically connected through the first magnet and the second magnet. A positioning assembly for positioning the placing rack is arranged at one end of the transmission rod facing the anti-collision box.

[0012] Preferably, the driving assembly includes electric push rods fixedly connected to both sides inside the box body. A support plate is fixedly connected to the tops of the two electric push rods. A plurality of vertical rods are fixedly connected to the top surface of the support plate, and a moving plate for cooperating with the bottom plate is fixedly connected to the top of the vertical rods.

[0013] Preferably, a plurality of drainage holes are opened on the bottom plate, and positioning columns for cooperating with the drainage holes are fixedly connected to the top surface of the moving plate.

[0014] Preferably, the top end of the positioning column is conical.

[0015] Preferably, the transmission ratio of the acceleration assembly is 1 / 2.

[0016] Preferably, a positioning plate is fixedly connected to the upper end of one side of the slide rail facing the open side of the box body. The positioning assembly includes an eccentric wheel fixedly sleeved on the transmission rod. A horizontal positioning block is arranged on one side of the eccentric wheel facing the positioning plate. A chute for the positioning block to move is penetrated through the side wall of the box body. An auxiliary groove is opened outward in the middle of the chute, and a rebound assembly for driving the positioning block to move towards the eccentric wheel is arranged in the auxiliary groove.

[0017] Preferably, a flange located in the auxiliary groove is fixedly connected to the outside of the positioning block, and a spring is arranged between the flange and the side wall of the auxiliary groove.

[0018] Preferably, an operating rod for facilitating the rotation of the driving rod is fixedly connected to one end of the driving rod located outside the placing rack, and the operating rod is located directly below the anti-collision box.

[0019] In summary, the technical effects and advantages of the present invention: For this watermelon and melon seedling cultivation device, the driving assembly drives the plurality of bottom plates in the same placing rack to move up and down, so as to realize the upward movement of the soil, seedlings and the bottom plate together, and further realize the batch transplantation of seedlings. Compared with the existing devices, the problem of needing to operate each plant individually is avoided, and the work efficiency is improved.

[0020] In addition, the driving rod cooperates with the acceleration component to drive the transmission rod, realize the rotation of the first magnet, and further realize the switching between attraction and repulsion between the first magnet and the second magnet, thereby controlling the mutual attraction of adjacent placement modules, avoiding the problem that the placement modules inside are not convenient to take out due to the excessive depth of the inner side of the box body, and further improving the work efficiency.

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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.

[0029] Referring to Figures 1-3 , a seedling cultivation device for western melons and melons includes a box body 1 with one side open, slide rails 2 are provided on both sides inside the box body 1, and a plurality of placement modules 3 are detachably and slidably arranged inside the box body 1 through the slide rails 2.

[0030] The placing module 3 includes a placing rack 5 with a plurality of cultivation cavities 4 penetrating through the top surface. On both sides of the placing rack 5, pulleys are fixedly installed for sliding within the slide rails 2. The cultivation cavity 4 is in the shape of a frustum of a cone with a larger upper part and a smaller lower part, and a matching bottom plate 6 is provided at the lower end of the cultivation cavity 4. By means of the cooperation between the bottom plate 6 and the cultivation cavity 4, the loading of the cultivation soil is realized. Below one end of the slide rail 2 close to the open side of the box body 1, a driving component is provided for driving the plurality of bottom plates 6 in the same placing rack 5 to move up and down.

[0031] At the upper parts of both ends on the side of the placing rack 5 facing the open side of the box body 1, anti-collision boxes 7 are fixedly connected, and driving rods 8 are rotatably provided at the lower parts of both ends. Cavities 9 are provided at both ends of the placing rack 5, and a transmission rod 10 and an acceleration component 11 for accelerating the transmission of the transmission rod 10 through the driving rod 8 are provided within the cavities 9. One end of the transmission rod 10 away from the anti-collision box 7 is fixedly connected with a first magnet 12, and a second magnet 13 is fixedly connected within the anti-collision box 7, and adjacent placing modules 3 are magnetically connected through the first magnet 12 and the second magnet 13. As Figure 1 、 Figure 3 shown, the first magnet 12 within the outermost placing module 3 and the second magnet 13 within the innermost placing module 3 cooperate with each other. A positioning component for positioning the placing rack 5 is provided at one end of the transmission rod 10 facing the anti-collision box 7.

[0032] When using this watermelon seedling cultivation device, soil and seeds should be placed into the cultivation cavity 4 first. After completion, both sides of the placing rack 5 are slidably connected within the box body 1 through the slide rails 2. After completion, rotate the driving rod 8 to change the direction of the first magnet 12. Continue to repeat the above operation. After the direction of the first magnet 12 in the outermost placing module 3 is changed, it is attracted to the second magnet 13 within the innermost placing module 3, thereby realizing magnetic connection. After all the placing modules 3 are placed, the seeds can be waited for to germinate.

[0033] When the watermelon seedlings grow to three leaves and one heart, the transplantation of the watermelon seedlings can begin. At this time, pull out the outermost placing rack 5 outward until the bottom plate 6 is directly above the driving component, and the innermost placing rack 5 moves along with it due to magnetic connection. At this time, the driving component drives the plurality of bottom plates 6 to move up simultaneously, that is, the separation of the seedlings from the cultivation cavity 4 is realized. The transplantation of the seedlings can then be carried out.

[0034] After completion, the driving component drives the plurality of bottom plates 6 to move down again and return to the bottom of the cultivation cavity 4. At this time, rotate the driving rod 8, and the first magnet 12 changes direction again. The first magnet 12 thus repels the second magnet 13, and the innermost placing module 3 no longer follows the outermost placing module 3 to move. At this time, the outermost placing module 3 can be taken out. Repeat the above operation to take out all the placing modules 3.

[0035] It should be noted that, compared with the open-air scheme, the scheme using the cultivation box can make the growth conditions such as the light of the seedlings more stable. Therefore, a fluorescent lamp can be arranged on the top of the box body 1. For watering, the schemes of manual watering or mechanical nozzle watering can be adopted. The above are all prior arts and will not be elaborated here.

[0036] The driving component, the slide rail 2 and the placing module 3 thereon in the box body 1 work together to realize the placement of multiple placing modules 3 in a row. When more placing modules 3 need to be placed, only the slide rail 2 and the corresponding driving component need to be added to realize the placement of multiple placing modules 3 in multiple rows. The applicability of the device is improved.

[0037] Refer to Figures 4-5 , the driving component includes electric push rods 14 fixedly connected to both sides inside the box body 1. A support plate 15 is fixedly connected to the tops of the two electric push rods 14 together. A plurality of vertical rods 16 are fixedly connected to the top surface of the support plate 15. A moving plate 17 cooperating with the bottom plate 6 is fixedly connected to the top of the vertical rod 16. By pushing the support plate 15 upward through the electric push rod 14, the moving plate 17 is used to drive the bottom plate 6 to move upward in cooperation with the vertical rod 16.

[0038] Among them, the length of the vertical rod 16 should be greater than the height of the cultivation cavity 4, so as to completely separate the bottom plate 6 from the cultivation cavity 4. It is convenient for subsequent taking of the seedlings.

[0039] A plurality of drainage holes 18 are formed in the bottom plate 6. A positioning column 19 cooperating with the drainage holes 18 is fixedly connected to the top surface of the moving plate 17. By inserting the positioning column 19 into the drainage holes 18, the positioning of the bottom plate 6 is completed, which is convenient for subsequent driving of the bottom plate 6 to move.

[0040] Since the drainage holes 18 may be blocked by soil, the top end of the positioning column 19 is conical, and the positioning column 19 is inserted into the drainage holes 18 accordingly.

[0041] It should be noted that, since the number of the drainage holes 18 is large to meet the drainage requirements, if the number of the positioning columns 19 is large, the contact area with the soil will increase, and it will be more difficult to insert into the drainage holes 18 for positioning. In addition, since the bottom plate 6 may rotate during the working process, the positions of the drainage holes 18 may change. Therefore, only one positioning column 19 is arranged on the top surface of the moving plate 17 to correspond to one drainage hole 18 at the center of the bottom plate 6.

[0042] One end of the driving rod 8 located outside the placing rack 5 is fixedly connected with an operating rod 26 convenient for driving the driving rod 8 to rotate, and the operating rod 26 is located directly below the anti-collision box 7. The anti-collision box 7 is used to prevent the placing rack 5 from directly colliding with the operating rod 26 when adjacent placing modules 3 move, and improve the operation stability of the device.

[0043] In addition, the anti-collision box 7 can also reduce the distance between the mating first magnet 12 and second magnet 13, preventing the first magnet 12 and second magnet 13 from being too far apart due to the presence of the operating rod 26 and the driving rod 8, which would cause the device to malfunction.

[0044] For the convenience of taking the placement rack 5, a handle for pulling is fixedly connected to the side of the placement rack 5 facing the open side of the box body 1, and the handle is also protected by the anti-collision box 7.

[0045] The acceleration assembly 11 is a prior art and can use the solution of a driving wheel, a driven wheel, and a synchronous belt. The transmission ratio of the acceleration assembly 11 is 1 / 2, that is, when the driving wheel rotates one week, the driven wheel rotates two weeks. In this way, when the rotating rod rotates 1 / 4 of a circle, the first magnet 12 just rotates 1 / 2 of a circle, changing the magnetic pole direction. It can be set that when the operating rod 26 is horizontal, the first magnet 12 just attracts the second magnet 13; when the operating rod 26 is vertical, the first magnet 12 just repels the second magnet 13. This facilitates personnel to observe and determine the magnetic pole state.

[0046] One side of the upper end of the slide rail 2 facing the open side of the box body 1 is fixedly connected with a positioning plate 20. The positioning assembly includes an eccentric wheel 21 fixedly sleeved on the transmission rod 10. A horizontal positioning block 22 is provided on one side of the eccentric wheel 21 facing the positioning plate 20. A chute 23 for the positioning block 22 to move is penetrated through the side wall of the box body 1. An auxiliary groove is opened outward in the middle of the chute 23, and a rebound assembly for driving the positioning block 22 to move towards the eccentric wheel 21 is provided in the auxiliary groove.

[0047] Through the eccentric wheel 21 and the rebound assembly, when the transmission rod 10 rotates, the positioning block 22 moves horizontally accordingly. It can be set that when the operating rod 26 is horizontal, one end of the positioning block 22 extends out of the chute 23 and cooperates with the positioning plate 20. At this time, the placement module 3 can only move on the slide rail 2 and cannot be disassembled and assembled; when the operating rod 26 is vertical, the positioning block 22 completely retracts into the chute 23. At this time, the placement module 3 can move, be disassembled and assembled freely on the slide rail 2.

[0048] In addition, when the positioning block 22 fits with the positioning plate 20, the bottom plate 6 should be directly above the corresponding moving plate 17. This facilitates personnel to align the bottom plate 6 with the moving plate 17. It improves the stability and operation convenience of the device.

[0049] It should be noted that since the placement rack 5 moves on the slide rail 2 through pulleys, the positioning plate 20 and the positioning block 22 cannot affect the rotation of the pulleys. Therefore, the distance between the bottom surface of the slide rail 2 and the bottom surface of the positioning plate 20 is greater than the diameter of the pulleys.

[0050] A flange 24 located in the auxiliary groove is fixedly connected to the outside of the positioning block 22. A spring 25 is arranged between the flange 24 and the side wall of the auxiliary groove. During the working process, the spring 25 always exerts a force on the flange 24 towards the eccentric wheel 21. AsFigure 6 As shown, the spring 25 is always in a compressed state.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
