Description

Technical Field

[0001] This utility model relates to the field of plug tray seedling technology, and more specifically to a lightweight functional plug tray seedling substrate. Background Technology

[0002] Plug seedling technology is a modern seedling technology that uses lightweight soilless substrate materials such as peat moss and vermiculite as seedling substrates, and mechanized precision sowing, one seed per hole, and one seedling per seedling. The plug seedling technology can be completed mechanically in the process of filling, sowing and germination, which is simple and quick to operate and suitable for large-scale production.

[0003] Tray seedling raising allows for one seed per hole and concentrated seedling raising, resulting in a higher seedling yield per unit area compared to conventional seedling raising. Using tray seedling raising can effectively increase the protected production area. The main function of the seedling tray is to provide an independent and suitable germination environment for seedlings, thereby promoting more refined seedling management and enabling mechanized operations.

[0004] Nowadays, when using seedling trays for plug seedling cultivation, after filling the trays with a substrate made from crushed straw, holes need to be pressed and dug in each cell of the tray. Currently, the common method is to place one seedling tray under the next to automatically complete the hole-digging. However, this method cannot guarantee the uniformity of each hole, and since the seedling trays are usually placed in one place, if the trays are tilted during the hole-digging process, it will also affect the final planting results. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lightweight functional seedling tray substrate to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a lightweight functional tray seedling substrate, including support legs, a support limiting frame fixedly connected to the top of the support legs, a balancing mechanism movably connected inside the support limiting frame, a tray seedling placed at the top of the balancing mechanism, a hole-digging mechanism movably connected inside the support limiting frame, the hole-digging mechanism being located above the tray seedling; the balancing mechanism includes a placement platform for placing the tray seedling, a limiting hole opened at the bottom of the placement platform, a limiting plate movably connected inside the limiting hole, a limiting rod fixedly connected to the bottom of the limiting plate, and a support spring sleeved on the side of the limiting rod.

[0007] Furthermore, a baffle plate is fixedly connected to the side of the supporting limiting frame. The side of the baffle plate is in contact with the side of the balancing mechanism, and the baffle plate completely blocks the side of the balancing mechanism.

[0008] Furthermore, the top end of the support spring contacts the bottom end of the placement platform, and the bottom end of the support spring contacts the interior of the support limiting frame. The number of the limiting plate, the limiting rod, and the support spring are all four.

[0009] Furthermore, the tray seedling raising includes a controllable servo motor, the top of which is fixedly connected to a threaded rod, and the top of the side of the threaded rod is threadedly connected to a perforation plate. The perforation plate is located above the tray seedling raising, and a perforation protrusion is formed below the perforation plate.

[0010] Furthermore, a disc stop is fixedly connected to the top of the threaded rod, and a limiting shaft is movably connected inside the perforated plate, with the bottom end of the limiting shaft fixedly connected to the ground.

[0011] Furthermore, a motor housing is fixedly connected to the side of the servo motor, and a connecting plate is fixedly connected to the top of the motor housing. The top of the connecting plate is fixedly connected to the bottom of the support limiting frame, and the servo motor is located inside the motor housing and the connecting plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model features a placement platform and seedling trays. Multiple seedling trays are stacked on top of each other and finally placed on the placement platform. When straw substrate is placed inside the seedling trays, the placement platform moves downward and compresses the support spring. The placement platform only moves horizontally downward, ensuring that the seedling trays are sufficiently level. Furthermore, the seedling trays themselves are relatively light, and the balancing mechanism provides constant support for the seedling trays, improving the digging effect.

[0014] 2. This utility model is equipped with a servo motor, a threaded rod, and a hole-digging plate. When the position of the seedling tray is kept horizontal and stable, the servo motor is started. When the servo motor is started, it drives the threaded rod to rotate. When the threaded rod rotates, it causes the hole-digging plate to move downward. When the hole-digging plate moves downward, it will contact the uppermost seedling tray. At this time, the lower part of the hole-digging plate will enter the seedling tray, thereby automatically completing the hole-digging work of the entire seedling tray. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 and Figure 2 This utility model provides a lightweight functional seedling tray substrate, including a support leg 1, a support limiting frame 2 fixedly connected to the top of the support leg 1, a balancing mechanism 4 movably connected inside the support limiting frame 2, a seedling tray 5 placed on the top of the balancing mechanism 4, a perforating mechanism 6 movably connected inside the support limiting frame 2, the perforating mechanism 6 being located above the seedling tray 5, and a shielding plate 3 fixedly connected to the side of the support limiting frame 2, the side of the shielding plate 3 contacting the side of the balancing mechanism 4, and the shielding plate 3 completely shielding the side of the balancing mechanism 4.

[0023] In this embodiment, when the seedling tray 5 is placed on the balancing mechanism 4, if straw substrate is added to the seedling tray 5, the height of the balancing mechanism 4 will change. The side of the balancing mechanism 4 is provided with a shielding plate 3, which can shield the balancing mechanism 4 and prevent the substrate from entering the balancing mechanism 4, so that the support spring 404 inside the balancing mechanism 4 cannot be compressed normally.

[0024] Reference Figure 3 and Figure 4 The balancing mechanism 4 includes a placement platform 401 for placing seedling trays 5. A limiting hole 405 is provided at the bottom of the placement platform 401. A limiting plate 402 is movably connected inside the limiting hole 405. A limiting rod 403 is fixedly connected to the bottom of the limiting plate 402. A support spring 404 is sleeved on the side of the limiting rod 403. The top of the support spring 404 contacts the bottom of the placement platform 401, and the bottom of the support spring 404 contacts the inside of the supporting limiting frame 2. There are four limiting plates 402, four limiting rods 403, and four support springs 404.

[0025] In this embodiment, when the placement platform 401 moves downward, it compresses the support spring 404. At this time, the placement platform 401 and the seedling tray 5 will move downward as a whole, which facilitates the smoothing work. After smoothing, when the seedling tray 5 is removed, the compressed support spring 404 will automatically reset and push the seedling tray 5 out, which facilitates the removal of the seedling tray 5. In addition, the placement platform 401 and the seedling tray 5 can maintain a horizontal state when moving, which helps to improve the smoothing effect.

[0026] Reference Figure 5 The tray seedling 5 includes a controllable servo motor 601. A threaded rod 602 is fixedly connected to the top of the servo motor 601. A perforated plate 604 is threadedly connected to the top of the side of the threaded rod 602. The perforated plate 604 is located above the tray seedling 5, and a perforated protrusion is provided below the perforated plate 604. A disc stop 603 is fixedly connected to the top of the threaded rod 602. A limiting shaft 607 is movably connected inside the perforated plate 604. The bottom end of the limiting shaft 607 is fixedly connected to the ground. A motor housing 605 is fixedly connected to the side of the servo motor 601. A connecting plate 606 is fixedly connected to the top of the motor housing 605. The top of the connecting plate 606 is fixedly connected to the bottom end of the support limiting frame 2. The servo motor 601 is located inside the motor housing 605 and the connecting plate 606.

[0027] In this embodiment, after the servo motor 601 is started, it drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, it drives the hole-digging plate 604 to move downward. When the hole-digging plate 604 moves downward, its lower part enters the seedling tray 5, thereby automatically performing all the hole-digging work in the seedling tray 5. The inner side of the hole-digging plate 604 is limited by the limiting shaft 607, thereby ensuring the stability of the hole-digging plate 604 during movement. The servo motor 601 is located inside the motor housing 605 and the connecting plate 606. The motor housing 605 and the connecting plate 606 can seal the servo motor 601 to prevent the substrate from entering the servo motor 601, thereby ensuring that the servo motor 601 can run for a long time without failure.

[0028] The working principle of this utility model is as follows: When filling the substrate of the seedling tray 5, multiple seedling trays 5 are placed as a whole in the support limiting frame 2. Since the seedling tray 5 is relatively light, the seedling tray 5 will not cause the balancing mechanism 4 to move downward. When the substrate supported by straw is placed on the seedling tray 5, the weight of the substrate is much greater than the weight of the seedling tray 5. Therefore, the seedling tray 5 will cause the placement platform 401 to move downward as a whole. At this time, the substrate on the seedling tray 5 can be smoothed.

[0029] Before leveling, after the substrate is placed in the tray seedling 5, the entire tray seedling 5 will move downwards to avoid the tray seedling 5 being too high and inconvenient for leveling. When the tray seedling 5 moves the placement platform 401 downwards, the placement platform 401 will compress the support spring 404. At this time, the tray seedling 5 is located within the support limit frame 2. When leveling, the support limit frame 2 will not move, maintaining its stability. After leveling the tray seedling 5, the servo motor 601 is started. After the servo motor 601 is started, it drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, it drives the hole-digging plate 604 to move downwards. When the hole-digging plate 604 moves downwards, the lower part of the hole-digging plate 604 enters the tray seedling 5, thereby automatically performing all the hole-digging work of the tray seedling 5.

[0030] After the hole is dug, the servo motor 601 controls the threaded rod 602 to reverse. After the threaded rod 602 reverses, the hole-digging plate 604 moves upward and moves from the seedling tray 5. At this time, the seedling tray 5 after the hole is dug can be removed. After the seedling tray 5 after the hole is dug is removed, the compressed support spring 404 will automatically reset and push the seedling tray 5 out. At this time, when adding substrate and smoothing the seedling tray 5, the operation will not be inconvenient due to the low position of the seedling tray 5.

[0031] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
