Description

Technical Field

[0001] This invention relates to the field of forestry planting technology, and in particular to a forestry planting seedling raising device. Background Technology

[0002] Forestry seedling cultivation is a crucial step in afforestation, ecological restoration, and timber production. Its goal is to cultivate high-quality seedlings with well-developed root systems, robust stems, and strong resilience, thereby promoting the sustainable development of forest resources. During seedling cultivation, the coordinated supply of water, nutrients, and oxygen is a key factor influencing seedling growth. The principles of advanced agricultural technologies such as soilless cultivation, tidal irrigation, and aeroponics have been gradually introduced into the field of forestry seedling cultivation, aiming to create a better air-water ratio environment for the roots, promote metabolism, and shorten the seedling cycle.

[0003] In conventional seedling trays, roots tend to protrude from the bottom drainage holes, causing "root penetration." When the seedlings are removed, the protruding roots are forcibly broken, resulting in root damage. The roots also become tangled at the bottom of the tray, affecting the normal formation of the root ball within the tray and hindering transplanting. While hydroponic seedling cultivation provides ample water and nutrients and facilitates environmental control, if the roots are completely submerged in the nutrient solution for an extended period, they are prone to root rot due to lack of oxygen.

[0004] Therefore, there is an urgent need to develop a forestry planting and seedling cultivation device that optimizes the rhizosphere environment, actively regulates root development, and facilitates batch seedling harvesting, in order to solve the problems in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a forestry planting and seedling raising device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a forestry planting and seedling raising device, comprising a box, a seedling tray, a bubble generating component, and a lifting component;

[0007] The box is a rectangular structure with an opening at the top. The upper and lower sides of the box are respectively connected to a water supply pipe and a drain pipe with a valve. The lower side of the box is equipped with a root cutting mechanism for cutting off the roots extending below the seedling tray. The four corners of the box are equipped with lifting drive mechanisms for adjusting the position of the seedling tray.

[0008] The seedling tray has several holes evenly arranged inside, and several water holes penetrating the seedling tray are provided around and below the holes.

[0009] The bubble generating assembly includes an air pump connected to an air supply pipe, which is connected to multiple branch pipes that extend into the chamber.

[0010] The lifting assembly is used to adjust the overall tilt angle of the seedling box. The lifting assembly includes a base fixed to the ground, a support block fixed to the side wall of the box, and multiple hydraulic rods. The two ends of the hydraulic rods are respectively hinged to the base and the support block.

[0011] Furthermore, a support platform is provided on the upper side of the seedling box, and an edge is provided around the seedling tray, which is supported above the support platform; the lifting drive mechanism includes multiple vertically arranged electric push rods, the fixed end of each electric push rod is connected to the seedling box, and the telescopic end is connected to the bottom edge of the seedling tray.

[0012] Furthermore, the front side of the box is symmetrically provided with supporting legs, and the rear sides of the box are symmetrically provided with rotating parts. The rotating parts are composed of a base and a rotating rod that are hinged to each other, and the rotating rod is fixed to the bottom of the box.

[0013] Furthermore, a water level sensor is installed inside the box.

[0014] Furthermore, the end of the air supply pipe near the air pump is a flexible hose, while the branch pipe is a rigid tube.

[0015] Furthermore, the branch pipe is equipped with an aeration element at its end, which is used to aerate and oxygenate the water in the tank.

[0016] Furthermore, the root cutting mechanism includes two guide rods symmetrically arranged inside the housing and a movable plate. A sliding sleeve is symmetrically arranged below the movable plate. The sliding sleeve is sleeved on the outside of the guide rod and slidably connected to the guide rod. A cutter is provided on the front side of the movable plate.

[0017] Furthermore, the movable plate is driven by a pull rope, one end of which is connected to the movable plate, and the other end extends to the outside of the box after passing through multiple reversing pulleys inside the box.

[0018] Furthermore, the seedling tray has a groove on the upper side of the trough, the groove being used to spread a breathable culture medium.

[0019] Furthermore, the inner wall of the pit is conical with a larger top and a smaller bottom, and the diameter of the water holes is smaller than the particle diameter of the seedling substrate.

[0020] The present invention has the following beneficial effects:

[0021] 1. In this invention, soaking in the nutrient solution ensures full absorption of water and nutrients, while rapid separation prevents long-term root hypoxia; simultaneously, the bubble generating component continuously oxygenates, promoting root respiration and metabolism. This dynamic cyclical environment better simulates ideal rhizosphere conditions than traditional static hydroponics or soil culture, effectively preventing root rot and stimulating root vitality.

[0022] 2. In this invention, the root-cutting mechanism at the bottom of the device can periodically cut off the downward-extending roots, which can control the root morphology, prevent root entanglement, and prevent the roots in the water holes from breaking due to tension when the seedlings are taken out, thereby improving the quality of seedlings leaving the nursery and the survival rate of transplanting.

[0023] 3. In this invention, the lifting component adjusts the tilt angle of the box through the hydraulic rod, so that the seedling tray is tilted, which facilitates the batch removal of seedlings. The cone shape and air permeability of the seedling tray grooves optimize the root ball formation effect of individual seedlings, making it easy to remove the seedlings from the tray without breaking them apart during transplanting, and making the transplanting process smoother and more efficient.

[0031] The present disclosure will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present disclosure more clearly, and should not be used to limit the scope of protection of the present disclosure.

[0032] Figure 1-3 This is a schematic diagram of the structure of a forestry planting and seedling raising device provided in this disclosure. See also... Figure 1-3 In this embodiment, each module (device, component, etc.) will be discussed in detail.

[0033] A forestry planting and seedling raising device, combined with attached Figure 1 , 6 It includes a box 1, a seedling tray 2, a bubble generating component, and a lifting component.

[0034] The box 1 is a rectangular structure with an opening at the top for inserting or removing the seedling tray 2. A water supply pipe 10 is connected to the upper side of the box 1, and a drain pipe 11 with a valve is connected to the lower side for regulating the nutrient solution level inside the box 1. Support legs 14 are symmetrically arranged on the lower front side of the box 1, and rotating parts 15 are symmetrically arranged on both sides of the rear. The rotating parts 15 consist of a base 150 and a rotating rod 151 that are hinged to each other. The rotating rod 151 is fixed to the bottom of the box 1, allowing the rear side of the box 1 to rotate around the hinge point. A water level sensor 16 is provided inside the box 1 for monitoring the liquid level.

[0035] The bubble generating assembly includes an air pump 30, an air supply pipe 31 connected to the air pump 30, and multiple branch pipes 32. The section of the air supply pipe 31 near the air pump 30 is a flexible tube, while the branch pipes 32 are rigid tubes extending to the bottom of the tank 1. An aeration element 33 is provided at the end of the branch pipe 32 for uniformly aerating the water in the tank 1 to increase the dissolved oxygen content.

[0036] Lifting drive mechanisms are provided at the four corners of the box 1. The lifting drive mechanism adopts a vertically set electric push rod 13, with the telescopic end connected to the bottom of the edge 22 of the seedling tray 2, which is used to adjust the position of the seedling tray 2 in the vertical direction. A support platform 12 is provided on the upper side of the box 1. The seedling tray 2 is surrounded by an edge 22, which is supported on the support platform 12 to keep the seedling tray 2 stable when it is not lifted.

[0037] Combined with appendix Figure 2 The seedling tray 2 has multiple holes 20 evenly arranged inside. The inner wall of the holes 20 has a conical structure that is larger at the top and smaller at the bottom. Multiple water holes 21 are provided around the holes 20 and at the bottom of the seedling tray 2. The diameter of the water holes 21 is smaller than the particle diameter of the seedling substrate to prevent substrate leakage. The seedling tray 2 has a groove 23 on the upper side of the holes 20, which can be used to spread a breathable culture medium to enhance root aeration.

[0038] Combined with appendix Figure 4The lower side of the box 1 is equipped with a root cutting mechanism for cutting the roots extending downward from the bottom of the seedling tray 2. The root cutting mechanism includes two guide rods 50 symmetrically arranged inside the box 1 and a movable plate 51 slidably connected to the guide rods 50. The lower side of the movable plate 51 cooperates with the guide rods 50 through a sliding sleeve 52, and a cutter 53 is installed on the front side. The movable plate 51 is driven by a pull rope 54. One end of the pull rope 54 is connected to the movable plate 51, and the other end extends to the outside of the box 1 after passing through multiple pulleys 55 arranged inside the box 1. The cutter 53 can be moved laterally by manual or mechanical pulling.

[0039] Combined with appendix Figure 3 , 5 The lifting assembly includes a base 40 fixed to the ground, a support block 41 fixed to the side wall of the box 1, and multiple hydraulic rods 42. The two ends of the hydraulic rods 42 are hinged to the base 40 and the support block 41, respectively. By extending and retracting the hydraulic rods 42, the box 1 can be tilted around the rear rotating member 15, thereby changing the overall angle of the box 1 and the seedling tray 2.

[0040] In specific implementation of this invention:

[0041] During seedling cultivation, the seedling substrate is first filled into the troughs 20 of the seedling tray 2, seeds are sown or seedlings are inserted, and the seedling tray 2 is placed on the support 12 inside the box 1. Nutrient solution is injected into the box 1 through the water supply pipe 10 until the liquid level submerges the lower part of the seedling tray 2. The water level sensor 16 monitors the liquid level height, and the air pump 30 is started. Air enters the nutrient solution through the air supply pipe 31, branch pipe 32 and aeration device 33 to form tiny bubbles, providing sufficient oxygen for the roots.

[0042] During the seedling cultivation process, the height of the seedling tray 2 can be adjusted according to the growth stage by using the electric push rod 13 of the lifting drive mechanism to control the depth of the roots immersed in the nutrient solution or to directly separate them from the nutrient solution. After separation, the air pump 30 continues to work and continuously inputs fresh air into the bottom of the box 1, realizing an alternating cycle of immersion and exposure to air, promoting root respiration and nutrient absorption. When some roots grow too long downward from the water hole 21 at the bottom of the seedling tray 2, the moving plate 51 and cutter 53 of the root cutting mechanism can be driven to move laterally along the guide rod 50 by pulling the pull rope 54, cutting off the excessively long roots extending from the bottom of the seedling tray 2, thus avoiding root entanglement.

[0043] During transplanting, the roots are cut again to facilitate the complete removal of the root ball. The nutrient solution in the box 1 is drained through the drain pipe 11. The hydraulic rod 42 of the lifting component is activated to gradually raise the front of the box 1, causing the box 1 and the seedling tray 2 to tilt backward at a certain angle. Since the pit 20 has a conical structure and smooth inner wall, the root ball of the seedling is easily removed from the pit 20 under the action of gravity after tilting. The operator can take out the seedlings along with the complete root ball in turn, realizing rapid batch seedling removal.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the invention, such designs should fall within the protection scope of the present invention.
