A clonal wet-grown pine seedbed

Abstract

This utility model relates to the field of wet-mixed pine seedling technology, specifically a clonal wet-mixed pine seedling bed, including a chamber embedded in a support assembly. The bottom surface of the chamber is provided with longitudinal and transverse grooves and a connected storage tank. A filter cover is installed in the groove. A liquid level sensor is installed on the side wall of the chamber, and a discharge connector with a butterfly valve is installed at the bottom. At the same time, a collection tank is provided on the outside, equipped with a suction pump connected to the liquid level sensor. The pumping end of the suction pump is directly aimed at the inside of the chamber to supply irrigation water. Water is guided through the grooves and seeps into the cultivation tank. When the liquid level sensor detects that the water level exceeds the limit, it shuts off the suction pump. At the same time, the motor is turned on and the butterfly valve of the discharge connector is opened. The remaining water is filtered through the storage tank and then flows back to the collection tank. The timer module automatically starts and discharges the remaining water according to a preset time to realize closed-loop water circulation. The whole system, through the coordinated action of groove guidance and intelligent control, accurately regulates the water retention time and recycling, eliminating the high energy consumption of drip irrigation and the defects of spraying caking, and significantly improving the seedling efficiency.

Description

Technical Field

[0001] This utility model relates to the field of wet-processed pine seedling technology, specifically to a clonal wet-processed pine seedling bed. Background Technology

[0002] The clonal wet-planted pine seedling bed is a nursery facility specifically designed for the mass cultivation of wet-planted pine hybrid seedlings with superior traits (such as fast growth, good trunk shape, and strong resistance) obtained through asexual propagation (such as tissue culture or cuttings). The seedling bed can overcome the disadvantage of seed propagation leading to the degradation of superior germplasm, ensuring the cultivation of commercial seedlings with highly consistent genetic quality and excellent traits, greatly improving the uniformity and economic value of the forest stand.

[0003] However, in traditional spraying systems, the impact of water flow can easily damage the arrangement of seedling tanks or wash away the surface substrate, while the slow infiltration of drip irrigation can easily form a closed water film at the bottom of the tank, hindering oxygen permeability. Neither of them can achieve a rapid and uniform deep water supply and drainage balance. Moreover, traditional sprinkler and drip irrigation rely on the continuous operation of the pump to maintain water pressure, which is not only energy-intensive but also unable to intelligently respond to actual water demand, and excess water is directly discharged, resulting in resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a clonal wet-grown pine seedling bed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A clonal wet-grown pine seedling bed includes a chamber body, which is embedded in a support assembly. Assembly plates are fixedly installed at the top edge of the chamber body. A liquid level sensor is fixedly installed on one side wall inside the chamber body. Several crisscrossing grooves are formed on the bottom surface of the chamber body. A storage tank is formed on one side of the bottom surface of the chamber body and communicates with the grooves. A filter cover is fixedly installed in the storage tank. A discharge connector is fixedly installed at the bottom of the chamber body opposite to the storage tank.

[0007] Preferably, a valve cylinder is threadedly installed at the bottom end of the discharge connector, a butterfly plate is provided inside the valve cylinder, a rotating shaft is fixedly installed on one side of the butterfly plate, and the rotating shaft passes through and extends to the outside of the valve cylinder to connect with a rotating motor.

[0008] Preferably, the rotary motor is bolted to the outside of the valve cylinder, and a timing module is fixedly mounted on the rotary motor. The rotary motor is connected to the timing module and the corresponding pins of the liquid level sensor via flexible wires.

[0009] Preferably, the support component includes a support frame, with a plurality of support plates welded at intervals to the bottom end of the support frame, and a hopper body embedded in the support frame. When the hopper body is embedded, the bottom end of the hopper body is attached to the top end of the support plates, and the assembly plate is attached to the top end of the support frame.

[0010] Preferably, a pressure plate is attached to the top of the assembly plate, and several fixing screws are inserted through the pressure plate and the assembly plate in the same position. The ends of the fixing screws are threaded into the top of the support frame.

[0011] Preferably, support legs are fixedly installed at the four corners of the bottom end of the support frame, support crossbars are fixedly installed between the support legs, and pads are fixedly installed at the bottom ends of the support legs.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This asexual wet-mixed pine seedling bed eliminates the problems of substrate compaction or tank displacement caused by surface water impact in spray / drip irrigation systems through the three-dimensional flow guiding network of grooves in the chamber and the directional flow confluence structure of the storage tank. At the same time, it avoids local over-wetting caused by continuous slow seepage of drip irrigation, and constructs a uniform and breathable root water absorption environment from a physical structure perspective.

[0014] 2. This asexual wet-planted pine seedling bed relies on a closed-loop control system to regulate the injection, retention and discharge in a coordinated manner, matching the intermittent water supply needs of wet-planted pine seedlings. Compared with the continuous pumping mode of spraying / drip irrigation, it directly reduces the continuous performance consumption of the water pump and achieves zero wastewater discharge and circulation.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0023] A clonal wet-grown pine seedling bed includes a chamber 101, which is embedded in a support assembly 113. An assembly plate 102 is fixedly installed at the top edge of the chamber 101. A liquid level sensor 103 is fixedly installed on one side wall inside the chamber 101. Several crisscrossing grooves 104 are formed on the bottom surface of the chamber 101. A storage tank 105 is formed on one side of the bottom surface of the chamber 101 and communicates with the grooves 104. A filter cover 106 is fixedly installed in the storage tank 105. A discharge connector 107 is fixedly installed at the bottom of the chamber 101 opposite to the storage tank 105.

[0024] The above solution provides the core space for wet-mixed pine seedling cultivation through the silo body; the supporting components ensure the overall load-bearing capacity and stability of the silo body; the assembly plates enable the positioning and docking of the silo body and the supporting components; the liquid level sensor monitors the internal water level in real time; the grooves ensure the uniform distribution and flow guidance of water at the bottom of the seedling bed; the storage tank collects and temporarily stores excess water; the filter cover prevents impurities from entering the drainage system; and the discharge connector establishes a controllable drainage channel.

[0025] In this embodiment, preferably, a valve cylinder 108 is threadedly installed at the bottom end of the discharge connector 107. A butterfly plate 109 is provided inside the valve cylinder 108. A rotating shaft 110 is fixedly installed on one side of the butterfly plate 109. The rotating shaft 110 passes through and extends to the outside of the valve cylinder 108 and is connected to the rotating motor 111.

[0026] The above scheme achieves a sealed connection of the drainage pipe through the threaded connection between the valve cylinder and the discharge connector; the opening and closing control of the drainage channel is achieved through the rotation of the butterfly plate inside the valve cylinder; the rotational power is transmitted to the butterfly plate through the rotating shaft; and the rotating motor provides a precise drive source to achieve automated drainage operation.

[0027] In this embodiment, preferably, the rotating motor 111 is bolted to the outside of the valve cylinder 108, and a timing module 112 is fixedly mounted on the rotating motor 111. The rotating motor 111 is connected to the timing module 112 and the corresponding pins of the liquid level sensor 103 via flexible wires.

[0028] The above scheme ensures stable operation of the drive components by fixing the rotating motor with bolts; it sets the drainage time logic and coordinates the motor's start and stop by using a timing module; and it establishes a linkage control between the water level signal and the drainage action by connecting the liquid level sensor, the timing module, and the rotating motor with flexible wires.

[0029] In this embodiment, preferably, the support component 113 includes a support frame 114, a plurality of support plates 115 are welded at intervals at the bottom end of the support frame 114, and a compartment 101 is embedded in the support frame 114. When the compartment 101 is embedded, the bottom end of the compartment 101 is attached to the top end of the support plate 115, and the assembly plate 102 is attached to the top end of the support frame 114.

[0030] The above solution provides a rigid support structure for the outer perimeter of the silo via a support frame; the support plate bears the load on the bottom of the silo and distributes the pressure; the embedded installation of the silo and the support frame enables rapid positioning; the fit between the bottom of the silo and the top of the support plate improves the overall structural stability; and the fit between the assembly plate and the top of the support frame ensures horizontal positioning accuracy.

[0031] In this embodiment, preferably, a pressure plate 116 is attached to the top of the assembly plate 102, and a plurality of fixing screws 117 are co-located inside the pressure plate 116 and the assembly plate 102. The ends of the fixing screws 117 are threadedly installed inside the top of the support frame 114.

[0032] The above solution enhances assembly clamping force by covering the assembly plate with a pressure plate; a fixing screw passes through the pressure plate and the assembly plate, and is then screwed to the top of the support frame to form a multi-point mechanical locking structure, eliminating the risk of displacement of the silo.

[0033] In this embodiment, preferably, support legs 118 are fixedly installed at the four corners of the bottom end of the support frame 114, support crossbars 119 are fixedly installed between the support legs 118, and pads 120 are fixedly installed at the bottom ends of the support legs 118.

[0034] The above scheme uses support legs to raise the seedbed to the operating height and transfer the load; support crossbars connect the support legs to form an anti-torsional frame; and pads increase the ground contact area to prevent settlement and isolate vibration interference.

[0035] In this embodiment, an asexual wet-grown pine seedling bed is used such that the support frame 114 is stably placed by the support legs 118 and the support crossbar 119 at the bottom. The pad 120 enhances the contact and anti-slip properties with the ground, ensuring overall stability. A support plate 115 is pre-installed inside the support frame 114. The silo body 101 is installed by embedding it into the support frame 114. At this time, the bottom end of the silo body 101 is precisely attached to the top end of the support plate 115 to evenly distribute the weight. At the same time, the assembly plate 102 at the top end of the silo body 101 is attached to the top edge of the support frame 114. Then, a pressure plate 116 covers the assembly plate 102, and a fixing screw 117 passes through the pressure plate 116 and the assembly plate 102 and is threaded to the top end of the support frame 114, thereby firmly locking the silo body 101. Within the support component 113, displacement and vibration are prevented. This assembly simplifies the installation process and enhances the overall structural strength. During the seedling stage, the wet-grown pine seedlings are first placed in cultivation tanks with permeable drainage holes at the bottom. These tanks are then evenly arranged on the bottom surface of the chamber 101, making full use of the space for support. A collection tank equipped with a suction pump is pre-installed at the seedbed. The collection tank is connected to the valve cylinder 108 via a pipe, and the pumping end of the suction pump is directly aimed at the interior of the chamber 101. Therefore, the suction pump can actively draw water from the collection tank and inject it into the chamber 101 for irrigation. During this process, the water injected into the chamber 101 is guided by the crisscrossing layout of the trenches 104 to quickly disperse to various locations and penetrate to the lowest layer of cultivation tanks. Absorption; The liquid level sensor 103 is fixed on one side wall of the chamber 101 to monitor the height of the storage tank 105 in real time. When the water level exceeds the set upper limit threshold, the liquid level sensor 103 sends a signal through a flexible wire to control the suction pump on the recovery tank to stop water intake. On the other hand, it simultaneously controls the rotation motor 111 to operate: the rotation motor 111 drives the rotating shaft 110 to rotate, causing the butterfly plate 109 to open in the valve cylinder 108. At this time, the excessively high water level in the chamber 101 is discharged from the discharge connector 107 to the preset recovery tank for temporary storage after passing through the storage tank 105 and being filtered by the filter cover 106. At the same time, the timing module 112 automatically calculates the appropriate residence time of water in the chamber 101 (mainly acting on the trench 104 and the bottom of the cultivation tank). When the set time arrives, the timer module 112 will instruct the rotating motor 111 to start and open the butterfly valve, discharging excess water and returning it to the recycling tank, completing one water cycle. This closed-loop water cycle mechanism works in conjunction with intelligent control to ensure automated and precise water management: the level sensor 103 links the opening and closing of the water source and the start of drainage, combined with the timer module 112 to irrigate and drain according to the growth needs, which is significantly different from the continuous operation of traditional drip irrigation or sprinkler systems; this design minimizes the outflow and waste of irrigation water, effectively prevents waterlogging disasters, and at the same time recycles and reuses water sources, and maintains the optimal humidity environment in the root zone through precise control; while the filter cover 106 effectively blocks substrate impurities from entering the discharge system and recycling tank, protecting the valves and water pumps and extending the service life of the system;The rigid structure of the support component 113 reduces the interference of vibration on the sensitive seedling environment; overall, it optimizes the closed-loop utilization efficiency of water resources, significantly reduces the intensity of manual monitoring and water replenishment costs, provides a stable and healthy root environment for clonal *Pinus thunbergii* seedlings, significantly improves seedling survival rate and promotes efficient growth.
