Description

Technical Field

[0001] This application relates to the field of agricultural planting technology, specifically to a seedling raising device for agricultural planting. Background Technology

[0002] Agricultural seedling raising devices are specialized equipment or systems used to cultivate seedlings. They are designed to provide a controllable and suitable environment for seed germination and seedling growth, thereby improving germination rate, seedling quality, and transplant survival rate. Their core function is to compensate for deficiencies in natural conditions by artificially adjusting key environmental parameters such as light, temperature, humidity, water, and nutrients, thus achieving efficient and standardized seedling raising.

[0003] In traditional seedling tray environments, seedlings often experience partial shading of leaves or stems by adjacent plants due to differences in planting density, plant shape, or light source layout. This shading leads to the shaded parts being in a low light intensity environment for a long time, significantly reducing photosynthetic efficiency and causing an imbalance in the plant's phototropic growth (such as excessive bending of stems and disordered leaf arrangement). Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a seedling raising device for agricultural planting, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a seedling raising device for agricultural planting, including a seedling box, a shifting seat slidably connected to the inner side of the seedling box, a seedling platform detachably mounted on the shifting seat, an LED light installed on the top inner side of the seedling box, a manual shifting mechanism for pushing out and storing the seedling platform on the seedling box, a rotating shaft rotatably connected to the top of the seedling platform, a seedling tray fixedly connected to the top of the rotating shaft, a seedling posture control mechanism for adjusting the seedling posture on the seedling platform, and a box cover detachably mounted on the opening of the seedling box.

[0006] Preferably, the manual shifting mechanism includes a crossbar fixedly inserted through the top of the seedling box, a rotating arm rotatably connected to the outer surface of the crossbar, and a handle fixedly connected to the top of the rotating arm. The manual shifting mechanism can push the shifting seat together with the seedling tray out of or into the seedling box, or store it inside the seedling box.

[0007] Preferably, a seat shaft is fixedly connected to the outer surface of the shifting seat, a drive bar is rotatably connected to the outer surface of the seat shaft, a connecting shaft is rotatably connected to the end of the drive bar away from the seat shaft, and the outer surface of the connecting shaft is rotatably connected to the bottom end of the rotating arm.

[0008] Preferably, the seedling position adjustment mechanism includes a slide groove on the top of the seedling tray, a rack plate slidably connected to the inner side of the slide groove, a small gear fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the small gear meshing with the outer surface of the rack plate. The seedling position adjustment mechanism can rotate the seedling tray to adjust the position of the seedling.

[0009] Preferably, the top of the seedling tray is rotatably connected to a rotating shaft, and a rotating disc is provided on the top of the rotating shaft.

[0010] Preferably, a large gear is fixedly sleeved on the outer surface of the disc shaft, and the outer surface of the large gear meshes with the outer surface of the rack plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This seedling raising device for agricultural planting allows the seedling tray to rotate continuously by manually turning the rotating disc, so that different parts of each seedling can receive light in turn.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-5 An agricultural seedling raising device includes a seedling box 1, a shifting seat 2 slidably connected to the inner side of the seedling box 1, a seedling platform 3 detachably installed on the shifting seat 2, an LED light 4 installed on the top inner side of the seedling box 1, the LED light 4 can provide a light environment for seedlings inside the seedling box 1, a manual shifting mechanism for pushing out and storing the seedling platform 3 is provided on the seedling box 1, a rotating shaft 11 is rotatably connected to the top of the seedling platform 3, a seedling tray 12 is fixedly connected to the top of the rotating shaft 11, a seedling posture control mechanism for adjusting the posture of the seedlings is provided on the seedling platform 3, and a box cover 19 is detachably installed at the opening of the seedling box 1.

[0022] Through the above technical solution, during the use of the seedling box 1, the seedlings are planted and cultivated in the seedling tray 12, and the seedling platform 3 is equipped with multiple seedling trays 12, which can cultivate multiple seedlings at the same time. During this period, the seedling tray 12 can be pushed out of the seedling box 1 by the manual shifting mechanism, or the seedling tray 12 can be put into the seedling box 1 from the outside. The position and posture of the seedlings can be adjusted by the seedling position and posture control mechanism.

[0023] Specifically, the manual shifting mechanism includes a crossbar 5 fixedly installed on the top of the seedling box 1, a rotating arm 6 rotatably connected to the outer surface of the crossbar 5, and a handle 7 fixedly connected to the top of the rotating arm 6.

[0024] Through the above technical solution, two sets of rotating arms 6 are set, located on both sides of the seedling box 1 respectively. When pushing and pulling the handle 7, the rotating arms 6 can be driven to swing, that is, the rotating arms 6 will rotate along the crossbar 5.

[0025] Specifically, a seat shaft 8 is fixedly connected to the outer surface of the shifting seat 2, a drive plate 9 is rotatably connected to the outer surface of the seat shaft 8, a connecting shaft 10 is rotatably connected to the end of the drive plate 9 away from the seat shaft 8, and the outer surface of the connecting shaft 10 is rotatably connected to the bottom end of the rotating arm 6.

[0026] With the above technical solution, strip-shaped holes are provided on both sides of the seedling box 1. This is to accommodate the movement of the seat shaft 8 and provide an operable space for driving the displacement seat 2 through the seat shaft 8.

[0027] Specifically, the seedling position control mechanism includes a slide groove 13 on the top of the seedling platform 3, a rack plate 14 slidably connected to the inner side of the slide groove 13, and a pinion 15 fixedly sleeved on the outer surface of the rotating shaft 11, with the outer surface of the pinion 15 meshing with the outer surface of the rack plate 14.

[0028] Through the above technical solution, the slide groove 13 is provided in two sets, and each set of slide groove 13 is provided with a rack plate 14. At the same time, both sides of the rack plate 14 have tooth pressure design, which can respectively mesh and drive a row of pinions 15.

[0029] Specifically, the top of the seedling platform 3 is rotatably connected to a disc shaft 16, and a rotating disc 17 is provided on the top of the disc shaft 16.

[0030] Through the above technical solution, the disc shaft 16 can be driven to rotate synchronously during the process of manually turning the disc 17, and the large gear 18 will also rotate with the disc shaft 16.

[0031] Specifically, a large gear 18 is fixedly sleeved on the outer surface of the disc shaft 16, and the outer surface of the large gear 18 meshes with the outer surface of the rack plate 14.

[0032] Through the above technical solution, during the rotation of the large gear 18, it will simultaneously drive the two sets of rack plates 14 that are meshed with it to rotate in opposite directions, wherein the two sets of rack plates 14 are symmetrically distributed on the outer periphery of the large gear 18.

[0033] Working principle: During use, seedlings are planted and cultivated in seedling trays 12 in the seedling box 1. Multiple seedling trays 12 are set on the seedling platform 3, allowing for the simultaneous cultivation of multiple seedlings. The LED lights 4 inside the seedling box 1 provide the necessary lighting environment for the seedlings in the seedling trays 12. During cultivation, it is necessary to regularly observe the seedling root development, leaf health (such as yellowing or disease spots), or differences in growth rate. At this time, the position of the seedling platform 3 is adjusted manually using the moving mechanism to push it out of the seedling box 1. This involves first removing the lid 19 from the opening of the seedling box 1, and then... Pull down handle 7 to rotate the rotating arm 6 along the crossbar 5. During the rotation of the rotating arm 6, its bottom end will drive the drive plate 9 through the connecting shaft 10, thereby causing the drive plate 9 to pull the seat shaft 8 during the deflection process (during this period, the two ends of the drive plate 9 will rotate with the seat shaft 8 and the connecting shaft 10 respectively). Finally, it will drive the displacement seat 2 to slide out of the seedling box 1, that is, the seedling platform 3 will move out at the same time, so as to make detailed observation of the seedlings in the seedling tray 12. Considering the differences in planting density, plant shape, or light source layout of the seedlings in the seedling tray 12, there may be local observations. The phenomenon of leaves or stems being shaded by adjacent plants affects the efficiency of photosynthesis. Therefore, the angle and posture of the seedlings can be flexibly adjusted as needed. This can be achieved by manually rotating the rotating disc 17 to drive the disc shaft 16. During this process, the large gear 18 will rotate accordingly, and the rotation of the large gear 18 will drive the two sets of gear plates 14 meshing with it to move synchronously, causing the gear plates 14 to slide along the sliding groove 13. The sliding of the gear plates 14 will then drive the small gear 15 meshing with it, thereby linking the rotating shaft 11 to synchronously rotate the seedling tray 12 above. During the rotation process, the angle and posture of the seedlings can be adjusted, dynamically changing the light-receiving surface of the leaves and slightly tilting the stems towards the light source, so that the shaded leaves are exposed to light again. Through this flexible adjustment of the seedling angle and posture, the transformation from "passively adapting to the environment" to "actively regulating the environment" can be achieved, providing key technical support for high-density and high-efficiency seedling cultivation. At the same time, the centrifugal force generated by the rotation of the seedling tray 12 and the synergistic effect of phototropism can induce the stems to form an optimized plant shape with a spiral upward growth, which not only meets the light requirements of the apical meristem but also enhances the mechanical strength of the stems.
