[0002] Common seedling cultivation methods include soilless cultivation with nutrient solution or soil cultivation. The survival rate of plants is improved by unified seedling cultivation and subsequent transplanting. For example, in the process of raising seedlings of Polygonatum cyrtonema, it is necessary to carry out soil cultivation. For example, a navel orange seedling raising device with the announcement number CN114568172B in the prior art relates to the technical field of navel orange seedling raising, including an operating box body, an operating slot is provided inside the operating box body, a horizontal support plate is slidably connected in the operating slot, axial springs are fixedly installed at the four end corners of the lower end surface of the support plate, the support plate is fixedly connected to the bottom end of the inner wall of the operating box body by a spring, and a control member for controlling the up and down vibration of the support plate is provided at the middle position of the bottom end of the inner wall of the operating slot. The navel orange seedling raising device can improve the efficiency of spreading the root system of the navel orange seedling while reducing the damage to the navel orange seedlings, and the soil blocks on the root system of the navel orange seedlings are loosened by vibration;

By arranging the soil self-loosening mechanism, when the soil is poured into the planting pot, the soil will first pass through the paddle bar in the vibration plate, so as to perform a regular separation and dispersion effect on the soil, and the soil will naturally fall to the bottom of the inner wall of the planting pot with gravity, and at the same time, the rotating handle is rotated to drive the rotating rod and the rotating plate to rotate, so that the soil can be paddled, and the soil can be peeled off one by one through the circular holes opened on the inner wall of the rotating plate, so that the soil that has lumped into a mass is fully broken up, and the inside is fully mixed evenly, so that the vegetable growth environment is better in the subsequent planting process, and the loosening work of the soil is simple to operate, thereby ensuring work efficiency;

[0004] In the prior art, soil is often prevented from becoming compacted and affecting seedling growth by vibrating or directly crushing the soil, or the soil's absorption efficiency of drip irrigation nutrient solution is improved by the above methods. Although the above methods can achieve the corresponding effects, when cultivating plants such as Polygonatum sibiricum and seedlings with fragile root systems, the roots and stems of the plants are easily damaged due to vibration or crushing operations, which is not conducive to Polygonatum sibiricum seedling cultivation. Summary of the invention

Although the above method can achieve the corresponding effect, when cultivating plants such as Polygonatum sibiricum and seedlings with fragile root systems, the roots and stems of the plants are easily damaged due to vibration or crushing operations, which is not conducive to Polygonatum sibiricum seedling cultivation.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a seedling raising box for planting Polygonatum cyrtonema with quantitative drip irrigation, comprising a pot body for filling soil and raising seedlings and a box body for accommodating the pot bodies at equal intervals, and a water tank for accommodating water for drip irrigation is provided below the box body, the pot body contains a space with variable volume, and the space in the single-row pot body in the box body can loosen the soil before and during drip irrigation and tighten the soil after drip irrigation through reciprocating volume changes, thereby improving the drip irrigation effect;

[0007] As a further feature, the seedling box also includes a drip irrigation mechanism disposed in the variable-volume space of the basin body, wherein the drip irrigation mechanism is linked to the power driving the volume change of the space and performs quantitative drip irrigation.

[0008] Furthermore, the variable volume space is composed of an internal space opened at the top of the basin body, and two side wall plates distributed oppositely in the space, wherein the edges of the side wall plates are horizontally slidably installed in the horizontal through grooves of the side walls of the basin body through elastic sheets, and at the same time, the back of the side wall plates is connected to a driving mechanism, which is used to drive the two side wall plates in a basin body to move synchronously in opposite directions.

[0009] As a further feature, the driving mechanism comprises a pull rod fixed to the back of the side wall plate, wherein the pull rod is horizontally slidably installed inside the side wall of the basin body, and the outer end of the pull rod is connected to a vertically distributed slide plate.

[0010] As a further feature, the slide plate is also horizontally slidably mounted on the side wall of the basin body, and the bottom end of the slide plate is threadedly connected to the threaded section of the rotating shaft. The rotating shaft horizontally distributed and rotatably mounted in the box body is connected to the output end of the motor, and the threaded transmission movement directions of the two slide plates in one basin body are opposite.

[0011] Furthermore, the drip irrigation mechanism includes a drip irrigation pipe and a water supply mechanism, wherein the top end of the drip irrigation pipe extends into the volume-variable space in the basin body, and the bottom end of the drip irrigation pipe is connected to the water supply mechanism through a connecting pipe, wherein the water supply mechanism is linked to the rotation of the rotating shaft, and the rotation of the rotating shaft produces the effect of supplying water toward the connecting pipe and the drip irrigation pipe.

[0012] Furthermore, the water supply mechanism includes a water cylinder arranged on one side of the box body, and a horizontal plate is vertically sealed and slidably installed inside the water cylinder. The one-way input end of the water delivery space below the horizontal plate is connected to the inside of the water tank, and the one-way output end is connected to the input end of the connecting pipe. The upper end surface of the horizontal plate is rotatably connected to the bottom end of the rocker, and the top end of the rocker passes through the top opening of the water cylinder and is rotatably installed at the edge of the right side of the circular plate, and the center of the circular plate is fixed to the outer end of the rotating shaft.

[0013] As a further feature, the drip irrigation mechanism comprises two arc-shaped pipes arranged in the area inside or above the soil, and the two oppositely distributed pipes will surround the root system in the soil or the periphery of the root system.

[0014] Furthermore, the one-way output end of the pipeline is connected to a drip irrigation head distributed toward the soil, while the one-way input end is directly connected to the water tank through a connecting pipe. A valve plate is sealingly and slidably installed inside the horizontal section, and the valve plate is connected to the side wall plate through a sliding rod. The movement of the side wall plate drives the valve plate to move together, so that the internal space pressure of a pipeline changes accordingly.

[0015] Furthermore, two oppositely distributed oblique rods are rotatably installed on the upper and lower ends of the sliding rod, and the top ends of the two adjacent oblique rods on the vertical plane are rotatably connected to the horizontally distributed cross rod, and the oblique rods and the cross rod are both located in the side area of ​​the internal space of the basin.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the seedling raising box for planting Polygonatum cyrtonema with quantitative drip irrigation can effectively loosen the soil and protect the root system of Polygonatum cyrtonema to the greatest extent by changing the spatial volume of the soil, and the power of changing the volume is used to achieve the irrigation effect at the same time, and the drip irrigation wetting area is increased by volume change and repeated loosening of the soil, thereby effectively improving the seedling raising efficiency, as shown in the following content:

[0017] 1. The structural design of the side wall plate and the surrounding elastic sheet can drive the two side wall plates in a box to move synchronously in opposite directions through the operation of the motor and the rotation of the shaft, and through the threaded connection between the shaft and the slide plate. The side wall plate is used to flexibly adjust the planting space in the box, so that the soil is intermittently in a state of being relaxed and squeezed, which can not only achieve the effect of loosening the soil to ensure air exchange, but also promote the full dispersion of the drip irrigation liquid and improve the root absorption effect;

[0018] Furthermore, the structural design of the circular plate and the rocker arm enables the rotation of the shaft to drive the horizontal plate to move back and forth up and down in the water cylinder, thereby generating a negative pressure conveying effect to convey the drip irrigation liquid without the need for additional water pump equipment. At the same time, the water pressure required for drip irrigation delivery is not high, and it will not significantly increase the motor operating load, which is more energy-saving and environmentally friendly.

[0019] 2. Use the pipeline structure in the soil distribution area or outside the plants above the soil. Through the structural design of the sliding rods and side wall plates at both ends of the pipeline, the movement of the side wall plates themselves can be used to generate a negative pressure conveying effect, so that the drip irrigation liquid in the water tank can follow the movement of the side wall plates to drip directly into the soil, and the drip irrigation effect is better;

[0020] Furthermore, the structural design of the oblique rod and the horizontal rod can follow the sliding of the sliding rod to drive the horizontal rod itself to move back and forth up and down, so that the horizontal rods in different positions can have different effects, such as loosening the soil from the side and repelling mosquitoes from the leaves of the plants, etc., which has a better effect.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0034] Embodiment 1: In this embodiment, the main purpose is to solve the problems existing in the prior art, such as Figure 1-Figure 2 As shown, it includes a basin body 1 for filling soil and raising seedlings, and a box body 2 for accommodating the basin bodies 1 at equal intervals, and below the box body 2 is a water tank 3 for accommodating water for drip irrigation. The basin body 1 contains a variable volume space, and the space in the single-row basin body 1 in the box body 2 realizes soil loosening before and during drip irrigation and soil tightening after drip irrigation through reciprocating volume changes, thereby improving the drip irrigation effect; at the same time, the seedling box also includes a drip irrigation mechanism arranged in the variable volume space in the basin body 1, wherein the drip irrigation mechanism is linked to the power for driving the volume change of the space and performs quantitative drip irrigation, and the variable volume space is composed of an internal space with an opening at the top of the basin body 1, and two side wall plates 5 distributed oppositely in the space, wherein the edge of the side wall plate 5 is horizontally slidably installed in the horizontal through groove of the side wall of the basin body 1 through an elastic sheet 6, and the back of the side wall plate 5 is connected to the driving mechanism, and the driving mechanism is used to drive the two sides in one basin body 1 The side wall plates 5 move synchronously in opposite directions. The solution in the embodiment is to use the reciprocating side wall plates 5 to achieve volume changes. When the driving mechanism drives the side wall plates 5 to move reciprocally, especially when the two oppositely distributed side wall plates 5 move synchronously in opposite directions, the internal space thereof will change accordingly. Specifically, when the two side wall plates 5 move in directions away from each other, the volume of the variable volume space in the above content will increase. At this time, the soil therein will be in a relatively loose state. At this time, if drip irrigation is performed from the inside of the soil, the drip irrigation water will soak the soil more quickly. After the drip irrigation is completed, the two side wall plates 5 are controlled to move back in a direction close to each other, so that the soil can be restored to a relatively compact state. The water drip-irrigated in a relatively loose state will soak a larger area of ​​soil. Therefore, after being relatively compacted, the moist space formed for the root system will be larger, effectively improving the effect of the root system absorbing water.

[0035] The following scheme is also disclosed in this embodiment, specifically: Figure 3As shown, the driving mechanism includes a pull rod 7 fixed to the back of the side wall plate 5, wherein the pull rod 7 is horizontally slidably installed inside the side wall of the basin body 1, and the outer end of the pull rod 7 is connected to a vertically distributed slide plate 8, and the slide plate 8 is also horizontally slidably installed on the side wall of the basin body 1, and the bottom end of the slide plate 8 is threadedly connected to the threaded section of the shaft 9, and the shaft 9 horizontally distributed and rotatably installed in the box body 2 is connected to the output end of the motor, and the threaded transmission movement directions of the two slide plates 8 in one basin body 1 are opposite, and the motor installed on the side of the box body 2 is used to drive the internal shaft 9 to rotate, and under the action of the double-stage reverse spiral thread transmission, the two slide plates 8 in one basin body 1 are driven to move synchronously in opposite directions, thereby producing a moving driving effect on the side wall plate 5.

[0036] In this embodiment, the following scheme is further disclosed, which is mainly to explain in detail how to utilize the dynamic linkage of the volume change of the basin body 1 and quantitative drip irrigation, such as Figure 3-Figure 4 As shown, the drip irrigation mechanism includes a drip irrigation pipe 20 and a water supply mechanism, wherein the top end of the drip irrigation pipe 20 extends into the volumetric variable space in the basin body 1, and the bottom end of the drip irrigation pipe 20 is connected to the water supply mechanism through a connecting pipe 4, wherein the water supply mechanism is linked to the rotation of the rotating shaft 9, and the rotation of the rotating shaft 9 produces the effect of supplying water toward the connecting pipe 4 and the drip irrigation pipe 20, and the water supply mechanism includes a water cylinder 10 arranged on one side of the box body 2, and a horizontal plate 11 is vertically sealed and slidably installed inside the water cylinder 10, and the one-way input end of the water delivery space below the horizontal plate 11 is connected to the inside of the water tank 3, and the one-way output end is connected to the input end of the connecting pipe 4, and the upper end surface of the horizontal plate 11 is rotatably connected to the bottom end of the rocker 12, and the top of the rocker 12 is penetrated The top of the water cylinder 10 is open and rotatably installed at the edge of the right side of the circular plate 13. The center of the circular plate 13 is fixed to the outer end of the rotating shaft 9. The rotation of the rotating shaft 9 will also drive the circular plate 13 to rotate. In order to enable the side wall plate 5 to move back and forth, the rotation of the rotating shaft 9 can be reciprocating rotation or unidirectional continuous rotation. It is only necessary to replace the thread segment with a reciprocating thread groove structure. When the rotating shaft 9 is in the process of rotation, the circular plate 13 will rotate synchronously, thereby driving the cross plate 11 to move back and forth up and down through the eccentrically installed rocker 12, so that the internal space of the water cylinder 10 below the cross plate 11 can achieve the water conveying effect through the change of pressure, so that the water flow can enter the drip irrigation pipe 20 through the connecting pipe 4 to complete the direct drip irrigation of the root system.

[0037] Embodiment 2: In this embodiment, a solution different from the above embodiment is disclosed, and the main difference is mainly reflected in the difference in the drip irrigation mechanism. For details, please refer to Figure 6-Figure 8The drip irrigation mechanism includes two arc-shaped pipes 14 arranged in the soil or above the soil. The two oppositely distributed pipes 14 surround the root system in the soil or the periphery of the root system. The one-way output end of the pipe 14 is connected with a drip irrigation head 15 distributed toward the soil, and the one-way input end is directly connected with the water tank 3 through the connecting pipe 4. A valve plate 17 is installed in the horizontal section in a sealing and sliding manner, and the valve plate 17 is connected to the side wall plate 5 through a sliding rod 16. The movement of the side wall plate 5 drives the valve plate 17 to move together, so that the internal space pressure of one pipe 14 is correspondingly strained. When the side wall plate 5 is in a reciprocating state, it will also drive the slide rod 16 to move, so that the two valve plates 17 in a pipe 14 move synchronously in the opposite direction. Similarly, the pipe 14 is provided with an inlet and outlet for unidirectional flow, which are respectively connected to the connecting pipe 4 and the drip irrigation head 15. Therefore, when the two valve plates 17 are away from each other, the inside of the pipe 14 is in a negative pressure state, and the water flow in the water tank 3 will directly enter the pipe 14 through the connecting pipe 4. When the two valve plates 17 are close to each other, an extrusion and conveying effect will be generated, so that the water will flow out of the drip irrigation head 15 and act on the soil.

[0038] Embodiment 3: In this embodiment, a scheme for loosening the soil is further disclosed, but the loosening method is auxiliary and is carried out from the side area of ​​the soil. In the repeated deformation process of the variable volume space, a better soil loosening effect can be achieved. Specifically, Figure 9-10 As shown, two oppositely distributed inclined rods 18 are rotatably installed at the upper and lower ends of the slide bar 16, and the top ends of the two adjacent inclined rods 18 on the left and right on the vertical plane are rotatably connected with the horizontally distributed cross rod 19, and the inclined rod 18 and the cross rod 19 are both located in the side area of ​​the internal space of the basin body 1. When the slide bars 16 at both ends of a pipe 14 move back and forth synchronously, the inclination angle will be changed during the rotation by driving the inclined rods 18 on both sides, and the cross rod 19 at the end will be driven to move back and forth up and down at the same time. When the inclined rod 18 and the cross rod 19 are in the soil, the soil will be more fully loosened in cooperation with the variable volume space, and when the cross rod 19 located outside the soil space moves up and down, it can drive away mosquitoes or dust that may exist in the blades by moving the blades, and the use effect is better.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
