[0021] The preferred embodiments of the application will be described in detail below with reference to the accompanying drawings. Here, the application will be described in detail with reference to the corresponding drawings. It should be particularly noted that the preferred embodiments described herein are only used to illustrate and explain the application, and are not used to limit or define the application.

[0022] As shown in Figures 1-4 A double-form hole disc device of a micro-hole hole disc wall includes a plurality of single hole discs 1 and a bottom disc 2, and a plurality of drainage holes 201 are formed on the bottom disc 2. The material of the hole disc is considered in terms of lightness, cost, flexibility, etc. For example, polystyrene is used, which has the advantages of light weight, easy operation and transportation, good heat preservation, which helps to promote the growth of seedlings at a certain temperature, and low cost. The plurality of single hole discs 1 are arranged in an array to form an overall hole disc, which is placed on the bottom disc 2, that is, the bottom surface of the overall hole disc is attached to the bottom disc 2. When the bottom disc 2 is moved, the substrate will not leak, and at the same time, each single hole disc 1 is provided with a corresponding drainage hole 201, and the wall plates of the plurality of single hole discs 1 in contact are fixed together, which can be fixed by bonding or a fixing member, to realize linkage deformation. Figure 1 、 Figure 2 As shown in

[0023] The upper and lower parts of the single hole disc 1 are open, which includes four wall plates of equal horizontal length, that is, the cross section of the single hole disc 1 is a parallelogram, and the adjacent two sides of the parallelogram are equal. The abutting position of the wall plates is connected by a hinged assembly 3, which can realize the relative rotation of the abutting wall plates, and by changing the included angle between the abutting wall plates, the cross-sectional shape of the overall hole disc can be converted between a parallelogram (non-rectangular) and a rectangle, and the shape can be converted between each other to adapt to different seedling taking modes and reduce the damage to seedlings caused by the two different seedling taking modes. The setting position of the drainage hole 201 should be ensured to correspond to each single hole disc 1 at all times. Compared with the traditional seedling raising hole disc, the hole disc has adaptability to the main seedling taking modes on the market, and the change in the density of the substrate during the seedling taking process is more matched to the corresponding seedling taking mode, which improves the efficiency of the seedling taking process and makes the seedling taking process more lossless.

[0024] As shown in Figure 6 、 Figure 7As shown, the structure of the hinge assembly 3 is not limited as long as it can realize the rotation of the two wallboards without large gaps between the two wallboards. For example, hinge, hinge, etc. Hinge connection structure. As shown Figure 7 As shown, the hinge assembly 3 is composed of a first sleeve 301, a second sleeve 302 and an embedded shaft 303. The first sleeve 301 is located on the side of the wallboard, and the second sleeve 302 is located on the side of the opposite wallboard. The number of second sleeves 302 is not less than one, and the optimal number is two, which are arranged above and below the first sleeve 301, for example: the first sleeve 301 on the wallboard A 102 and the second sleeve 302 on the wallboard B 103. The embedded shaft 303 passes through the coaxially aligned first sleeve 301 and second sleeve 302 to realize the relative rotation between the opposite wallboards. The overall height of the first sleeve 301 and the second sleeve 302 is basically the same as the height of the wallboard, which ensures that the bottom of the hinge assembly 3 is attached to the chassis 2. The embedded shaft 303 is connected to the hole plate wall and gives each single hole plate connection when the activity is converted. The entire hole plate is actively morphed through the embedded shaft.

[0025] As shown Figure 5 As shown, the embedded shaft 303 at any corner position of the overall hole plate extends into the chassis 2 to fix the overall hole plate, and the remaining embedded shafts only act as shafts. As shown Figure 2 、 Figure 3 As shown, the embedded shaft 303 at the upper left corner acts as a fixed shaft 4. The fixed shaft penetrates the chassis 2 at any hole plate vertex of the four vertices of the overall hole plate, and the overall hole plate is fixed by a fixed shaft to fix the hole plate position. In this way, the overall hole plate is fixedly connected to the chassis 2, which can also play a positioning role. After having a fixed point, the deformation direction is limited, which prevents the position from being too large during the deformation process due to the absence of a fixed point, and facilitates the deformation force.

[0026] 1. Hole plate conversion:

[0027] (1) The characteristics of the insertion type seedling taking are that the insertion type seedling taking is through the insertion tool into the substrate to grab the root system and the substrate. The substrate is required to be loose. If the substrate is too tight, the tool will encounter resistance when inserted, which will cause the root system to be damaged or the seedling body to be damaged. Loose substrate can reduce the insertion resistance, making the seedling taking process more smooth, and also reducing the damage to the seedlings. Insertion type seedling taking: when the density is 0.8-1.2 g / cm3, it is more suitable.

[0028] (2) Ejection type seedling taking feature is that the seedling is taken out from the bottom by applying an upward force. The requirement for the density of the substrate is relatively high. The denser substrate can better fix the seedling body and ensure the integrity of the root system and the substrate during ejection. Too loose substrate may cause the seedling body to be unstable during ejection, and even may cause root breakage or seedling body falling off. Ejection type seedling taking: when the density is 1.2-1.6 g / cm3, it is more suitable.

[0029] Therefore, according to different seedling taking methods, the density or looseness of the substrate indeed affects the seedling taking effect and the integrity of the seedling. In practical application, selecting appropriate substrate density can improve the efficiency and survival rate of seedling taking.

[0030] In summary, the insertion type seedling taking is suitable for loose substrate, which helps to reduce damage. The ejection type seedling taking is suitable for denser substrate, which helps to maintain the integrity of the seedling body. Therefore, it is proposed to adjust the density of different substrates in the plug tray device to better meet different seedling taking methods.

[0031] According to the area and volume change characteristics of different graphic models, the area of parallelogram is S=a (base) x h (height), the area of rectangle is a (base) x b (height), and the length of the base a is fixed. When the parallelogram is converted to a rectangle, its height (h) gradually becomes the height (b) of the rectangle. According to the knowledge of triangle, the longest side is in the triangle, so b>=h. At the same time, the height of the solid structure remains unchanged, so the volume of the parallelogram gradually increases when it is converted to a rectangle. When the volume of the pot seedling substrate with the same capacity decreases, the density increases.

[0032] Structurally, in the square form of the single plug tray 1, the four corner angles are 90 degrees, and the stress in each direction is relatively uniform. The substrate can be relatively loose in each hole of the plug tray. Due to the regular shape, the distribution and filling of the substrate in it are natural, the gap between the substrate particles is large, and the density is low, which is helpful for insertion type seedling taking. At this time, the particles of the substrate can slide or adjust freely to reduce the friction and damage of the seedling root system. When converted to a parallelogram shape, the change of the angle of the parallelogram will cause the substrate in the single plug tray to be squeezed to a certain extent, especially along the direction of shape change. The originally regularly distributed substrate particles are forced to rearrange.

[0033] The conversion from square to parallelogram changes the internal structure of the plug. Square is a symmetrical form, the force on the four corners is uniform, and the substrate is in a natural loose state in the plug. With the conversion of the plug to the parallelogram form, the angle of the plug changes, generating greater lateral pressure. This deformation increases the extrusion of the substrate along the diagonal direction, causing the arrangement of the substrate to be more compact. During the morphological conversion, the porosity in the substrate decreases, the contact between the particles increases, and the extrusion causes the volume of the substrate to decrease slightly, and the density increases. At this time, the ejection type seedling taking can be used. For the relatively loose substrate, the substrate is loose and has good air permeability when it is square, and after conversion to parallelogram, the pores are compressed and the substrate becomes more compact. When the single plug 1 recovers from parallelogram to square, the extrusion force on the substrate decreases, and the originally extruded substrate particles have more free space to adjust their positions and restore the loose state. The substrate density decreases, the gap between the particles increases, and the substrate becomes relatively loose. At this time, the insertion type seedling taking can be used to reduce the damage to the seedling roots.

[0034] The bottom plate 2 has an area larger than the bottom surface of all the connected plugs, and the shape and position of the bottom plate 2 do not change during the conversion process. The single plug 1 is large enough, and the drainage hole 201 is small enough, so the position of the drainage hole 201 does not change much before and after the conversion. The overall plug can be stretched from a rectangular plug with a rotating shaft to a plug with a parallelogram top and bottom surface. The volume of the single plug changes during the conversion, and the density of the substrate also changes accordingly.

[0035] When the culture substrate is formed, it can be first fixed as a parallelogram, and then converted to a rectangle when transplanting is needed. The plug is loose, and the density is also loose accordingly. This case is suitable for insertion type seedling taking. Conversely, if it is converted from a rectangle to a parallelogram, the volume decreases, which is suitable for ejection type seedling taking.

[0036] The plug device provides a plug with a parallelogram-shaped opening on the upper and lower surfaces, which has flexible conversion and can be converted to a rectangular plug with a rectangular upper and lower surface by embedding a shaft or the like. In this way, the overall shape can be changed by changing the angle between the unit cells without changing the unit cells themselves. The plug device can change the density of the substrate by morphological conversion, and the corresponding morphological conversion corresponds to different densities and corresponding seedling taking methods, which enhances the low damage rate of the substrate after seedling taking.

[0037] 2. Plug wall adhesion reduction

[0038] A plurality of micro-holes 101 for draining and preventing matrix particles from passing through are formed on the wall plate. The application of micro-hole technology in plug design mainly reduces the contact area between the matrix and the wall plate by creating small holes in the inner wall of the plug, thereby reducing adhesion. At the same time, the size of the micro-holes 101 needs to be carefully controlled to ensure that they are small enough to prevent matrix particles from passing through, but not too small to affect the air permeability and drainage of the plug. The micro-hole plug wall plate can enable the plug to achieve a more complex structure in a limited space, reduce the contact between the matrix and the wall plate, and reduce adhesion. In addition, micro-holes can also provide better drainage and air permeability, which is conducive to the healthy growth of plant roots.

[0039] The specific use process is as follows: as shown in Figure 1 , Figure 3 , the fixed form of the two plugs of the invention, the adhesion connection between the wall plates of each adjacent single plug 1 in the plug device, the fixed shaft penetrating the bottom plate at the top of one plug, and the overall plug fixed by a structure 1 fixed shaft to fix the position of the plug, thereby satisfying the fixed connection between the plug and the bottom plate. The four wall plates of each single plug 1 are connected by a hinged component 3. When the matrix is cultured, it is first fixed in a parallelogram shape as shown in Figure 3 , then the matrix is added, and then the seed is planted in the hole in the matrix, and the matrix density can be used for ejection type seedling taking; when the seedlings grow and the transplanting step is to be performed, if the plug is to be applied to an insertion type seedling taking device, the plug is pushed to change shape, and the plug changes shape through the hinged component 3. The plug changes to a Figure 1 rectangular shape, at which time the four corner angles are 90 degrees, and the stress in each direction is relatively uniform, and the matrix can be relatively loosely filled in each hole of the plug. Due to the regular shape, the distribution and filling of the matrix in it are more natural, the gap between the matrix particles is larger, the matrix in the plug is in a natural loose state, and the volume capacity decreases from small to large, and the matrix density decreases. This condition is suitable for the clamping stem and clamping pot insertion type seedling taking method, and after the mechanical claw clamps the stem or the pot, it clamps out the pot seedling upward, and the matrix is relatively loose. At the same time, due to the effect of the micro-holes 101, the contact between the matrix and the wall is reduced, and the drainage is increased, not only reducing the adhesion between the matrix and the wall, but also making it easier to clamp out while reducing the adhesion of the matrix to the wall. Conversely, when the matrix is cultured, it is first fixed in a rectangular shape as shown in Figure 1 , then the matrix is added, and then the seed is planted in the hole in the matrix, and the matrix density can be used for ejection type seedling taking; when the seedlings grow and the transplanting step is to be performed, if the plug is to be applied to an insertion type seedling taking device, the plug is pulled to change shape, and the single plug changes shape through the hinged component 3. The overall plug changes to Figure 3The parallelogram shape, as the whole hole disc changes to the parallelogram shape, the angle of the single hole disc changes, and greater lateral pressure is generated. This deformation increases the extrusion of the matrix along the diagonal direction, resulting in a more compact arrangement of the matrix. During the shape conversion process, the porosity in the matrix decreases, the contact between the particles increases, the extrusion effect slightly reduces the volume of the matrix, the density increases, and the volume capacity decreases from large to small, the matrix compactness increases, which is suitable for ejection type seedling taking, the insertion needle is inserted from the drainage hole, because the matrix is more compact, the upward ejection of the matrix increases the robustness, and the damage degree is reduced during ejection. At the same time, due to the effect of the micropore 101, the contact between the matrix and the wall plate is reduced, the drainage is increased, not only the adhesion between the matrix and the wall plate is reduced, but also the humidity of the matrix is appropriately reduced, the viscosity is reduced, and the ejection type seedling taking is more low-loss.

The present application can have various changes and variations for those skilled in the art or technicians. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope declared by the present application.
