Technical Field
[0001] This utility model relates to the technical field of seed testing equipment, specifically a device for testing the germination rate of off-season vegetable seeds. Background Technology
[0002] When growing vegetables out of season, it is necessary to conduct germination rate tests on vegetable seeds to facilitate the detection of seed quality. Vegetables grown out of season are generally summer vegetables grown in winter. Existing seed germination rate test equipment includes constant temperature chambers, temperature sensors, heat insulation layers, and heat insulation boards.
[0003] A search revealed that patent CN221995976U, an authorized patent, discloses an experimental device for the germination rate of off-season vegetable seeds. This invention includes a shell, a supplementary lighting device, and a drip irrigation device. The shell includes a base shell with an arc-shaped cover on top. The arc-shaped cover has two layers. One end of the upper layer of the two arc-shaped covers has a circular shell. Inside the circular shell is a rotating shaft, and three steel ruler strips are arranged around the outer circumference of the rotating shaft. The ends of the three steel ruler strips extend from the circular shell to the space between the two arc-shaped covers. Two black films are placed between the two layers of arc-shaped covers. This invention is an experimental device for the germination rate of off-season vegetable seeds, which is less affected by external environmental differences, has simple technology, is easy to operate, and has low manufacturing costs.
[0004] However, the above-mentioned technical solutions still have the following shortcomings in practical use: the above-mentioned devices involve opening a movable door to put soil, seeds, fertilize, or perform other operations inside the device. This method is inconvenient for sowing and fertilizing operations in the middle of the device and on the side opposite the movable door, resulting in poor ease of use. To address these issues, we propose an experimental device for the germination rate of off-season vegetable seeds. Utility Model Content
[0005] The purpose of this invention is to provide an experimental device for the germination rate of off-season vegetable seeds, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an experimental device for the germination rate of off-season vegetable seeds, comprising:
[0007] The base is a rectangular cavity with an opening at the top. An arc-shaped cover is installed at the top of the base, and an opening is provided at the front end of the base. Four support legs are fixedly welded to the bottom wall of the base. A cover plate is attached to the front outer wall of the base, and a planting box is fixedly installed on the inner wall of the cover plate. Two fixed seats are fixedly welded to the bottom wall of the base, and screws are rotatably installed on the two fixed seats. A servo motor is fixedly installed on the outer wall of the rear fixed seat, and the output end of the servo motor is connected to the screw drive. A movable seat is threadedly connected to the screw. An L-shaped connecting rod is fixedly welded to the front wall of the cover plate, and one end of the L-shaped connecting rod is fixedly welded to the movable seat.
[0008] Preferably, two support rods are fixedly welded to the front side wall of the cover plate, and a first roller is installed at the bottom end of the support rod.
[0009] Preferably, two second rollers are fixedly installed on the bottom wall of the planting box near the rear end, and the second rollers are rotatably connected to the bottom inner wall of the base.
[0010] Preferably, sliders are fixedly welded to both sides of the planting box near the rear end, and grooves are provided on both sides of the inner wall of the base, with the sliders slidably connected in the grooves.
[0011] Preferably, a sealing gasket is fixedly installed on the rear side wall of the cover plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, the servo motor can drive the screw to rotate in the forward direction, causing the moving seat to move away from the servo motor on the screw. When the moving seat moves, the cover plate can be moved forward away from the base via the L-shaped connecting rod, thereby pulling the planting box out of the base. This makes it convenient to place soil, plant seeds, and fertilize in the planting box, improving the freedom of operation and the ease of use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 This utility model provides a technical solution: an experimental device for the germination rate of off-season vegetable seeds, comprising:
[0020] The base 1 is a rectangular cavity with an opening at the top. An arc-shaped cover is installed at the top of the base 1. The arc-shaped cover is a publicly available technology and is not shown in the figure. The front end of the base 1 has an opening 2. Four support legs 3 are fixedly welded to the bottom wall of the base 1. A cover plate 4 is attached to the front outer wall of the base 1. A planting box 5 is fixedly installed on the inner wall of the cover plate 4. Two fixing seats 6 are fixedly welded to the bottom wall of the base 1. Screws 7 are rotatably installed on the two fixing seats 6. A servo motor 8 is fixedly installed on the outer wall of the rear fixing seat 6. The output end of the servo motor 8 is connected to the screws 7. A movable seat 9 is threadedly connected to the screws 7. An L-shaped connecting rod 10 is fixedly welded to the front wall of the cover plate 4. One end of the L-shaped connecting rod 10 is fixedly welded to the movable seat 9.
[0021] Two support rods 11 are fixedly welded to the front side wall of the cover plate 4. The bottom end of the support rod 11 is equipped with a first roller 12. The support rod 11 and the first roller 12 can easily support the cover plate 4 and ensure the stability of the front end support of the planting box 5 after it is removed from the base 1.
[0022] Two second rollers 13 are fixedly installed on the bottom wall near the rear end of the planting box 5. The second rollers 13 are rotatably connected to the bottom inner wall of the base 1. The second rollers 13 are used to stably support the rear end of the planting box 5.
[0023] The planting box 5 has sliders 14 fixedly welded to both sides near the rear end. The base 1 has grooves 15 on both sides of the inner wall. The sliders 14 are slidably connected in the grooves 15. The sliding cooperation between the sliders 14 and the grooves 15 facilitates positioning and guidance when the planting box 5 moves.
[0024] A sealing gasket is fixedly installed on the rear side wall of the cover plate 4, which can improve the sealing performance of the cover plate 4 and the base 1 after they are closed.
[0025] Working principle: In use, the planting box 5 is used to place soil and plant seeds. The servo motor 8 drives the screw 7 to rotate forward, causing the movable seat 9 to move away from the servo motor 8 on the screw 7. When the movable seat 9 moves, it can drive the cover plate 4 to move forward away from the base 1 through the L-shaped connecting rod 10, thereby pulling the planting box 5 out of the base 1. This facilitates the placement of soil, planting of seeds, and fertilization in the planting box 5, improving the freedom of operation and ease of use. After the operation is completed, the servo motor 8 can drive the screw 7 to move in the opposite direction, causing the movable seat 9 to reset on the screw 7, thereby storing the planting box 5 in the base 1 for seed cultivation.
