Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a double-form plug tray device with microporous plug tray walls. Background Art

[0002] Plug tray seedling cultivation is a modern seedling cultivation technology that uses plastic plug trays as seedling containers, peat, vermiculite, perlite and other lightweight materials as cultivation substrates, sowing seeds one by one in each hole, and centrally controlling and managing the seedling cultivation environment. Plug tray seedling cultivation has the advantages of high germination rate, good uniformity, short seedling recovery period after transplanting, less pests and diseases, labor saving and time saving, etc. It represents the development direction of seedling cultivation technology and is welcomed by growers.

[0003] Chinese researchers have conducted extensive research on fully automatic transplanting technology and have achieved many representative research results. However, there are still problems such as mismatch between agricultural machinery and agronomy, easy damage to seedlings in trays, and low success rate of machine seedling removal. Therefore, most of the research is still in the laboratory stage and cannot be applied to actual transplanting operations. We must rely on independent research and development, starting from key aspects such as the seedling raising process of tray seedlings suitable for mechanized automated transplanting in my country and the efficient and low-loss fully automatic seedling removal and throwing methods, and propose a seedling raising method that enhances the mechanical properties of the tray seedling pot, and create a fully automatic seedling removal mechanism that is highly reliable, efficient, and can achieve large-scale production operations.

[0004] However, most transplanting machine seedling claws in the prior art are clamping type or push-out type seedling claws, among which the existing clamping seedling claws can only be used for pot clamping seedlings or stem clamping seedlings, and secondly, they cannot be used for the above two types of clamping seedling methods at the same time. Further research is needed on these two optimization methods of low-loss seedling picking.

[0005] In addition, when the mechanical claws of the seedlings are used to grab the seedlings out of the plug tray, some of the matrix may remain in the plug tray when the seedlings are taken out, due to factors such as the composition material, humidity, and density of the matrix. By studying these factors, reducing the residual matrix in the plug tray can improve the efficiency and survival rate of transplanting. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a dual-form plug tray device with a microporous plug tray wall, which can adapt to the main seedling picking methods on the market. During the seedling picking process, the density of the matrix is ​​changed to better match the corresponding seedling picking method, thereby improving the efficiency of the seedling picking process and picking seedlings with lower loss.

[0007] In order to achieve the above technical objectives, the technical solution adopted is: a dual-form hole tray device with a microporous hole tray wall, including multiple single hole trays and a bottom plate, the bottom plate is provided with multiple drainage holes, multiple single hole trays are arranged in an array to form an overall hole tray and placed on the bottom plate, so that each single hole tray corresponds to a drainage hole, and the contacting wall panels of multiple single hole trays are fixed together, the upper and lower parts of the single hole tray are open, and it includes four wall panels with equal lateral lengths, and the docking positions of the wall panels are connected by a hinge assembly, and the hinge assembly can realize the relative rotation of the adjacent wall panels, and by changing the angle between the adjacent wall panels, the cross-sectional shape of the overall hole tray can be converted between a parallelogram and a rectangle.

[0008] The hinge assembly consists of a first sleeve, a second sleeve and an embedded shaft. The first sleeve is located on the side of the wall panel, and the second sleeve is located on the side of the adjacent wall panel. The embedded shaft passes through the coaxially aligned first sleeve and second sleeve to achieve relative rotation between the adjacent wall panels.

[0009] The embedding shaft at any vertex position of the integral plug tray extends and is inserted into the bottom plate to fix the integral plug tray.

[0010] The wall plate is provided with a plurality of micro holes for draining water and preventing the matrix particles from passing through.

[0011] The beneficial effects of the present invention are: 1. This device changes the pressure of the seedling pot matrix in the hole tray by changing the overall hole tray shape and the volume capacity of the hole tray, thereby changing the density of the matrix to adapt to the density suitable for different seedling removal methods, thereby increasing the robustness of seedling removal and the degree of damage to the seedling pot. Compared with using other devices to change the density of the matrix, this device has a simple structure and low cost.

[0012] 2. Without affecting the overall transformation of the plug tray, determine the position of the top angle to prevent the overall plug tray from shifting and being unable to align with the drainage hole. At the same time, it is also convenient for deformation and force application. The deformation operation can be achieved by pulling the other end of the diagonal angle, while ensuring the fit with the chassis.

[0013] 3. The microporous structure of the plug tray wall designed in the present invention has an appropriate size, which increases the drainage while ensuring that the substrate will not be lost or leaked. It not only reduces the contact between the substrate and the wall and reduces adhesion, but also appropriately reduces the humidity of the substrate and reduces viscosity. The increase in air permeability also helps the growth of the roots of the plug tray. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The preferred embodiments of the invention are given below in conjunction with the accompanying drawings to explain the technical solution of the present invention in detail. Here, the corresponding drawings are given to explain the present invention in detail. It should be particularly noted that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit or restrict the present invention.

[0016] like Figure 1-Figure 4 As shown, a dual-form hole tray device with a microporous hole tray wall includes a plurality of single hole trays 1 and a bottom tray 2. The bottom tray 2 is provided with a plurality of drainage holes 201. The material used to make the hole trays takes into consideration lightness, cost, flexibility, etc. For example, polystyrene is used, which has the advantages of being light in weight, easy to operate and transport, having good thermal insulation properties that help promote the growth of seedlings at a certain temperature, and having low cost. A plurality of single hole trays 1 are arranged in an array to form an overall hole tray that is placed on the bottom tray 2, which ensures that the bottom surface of the overall hole tray fits with the bottom tray 2. When the bottom tray 2 is moved, the matrix will not leak out. At the same time, each single hole tray 1 is provided with a corresponding drainage hole 201, and the contacting wall panels of the plurality of single hole trays 1 are fixed together. The fixing can be achieved by bonding or fixing with fixing parts to realize linkage deformation. Figure 1 , Figure 2 As shown, the number of single-cell trays 1 is 9, corresponding to 9 drainage holes 201 .

[0017] The upper and lower parts of the single hole tray 1 are open, and it includes four wall panels with equal transverse lengths, that is, the cross section of the single hole tray 1 is a parallelogram, and the two adjacent sides of the parallelogram are equal. The docking positions of the wall panels are connected by a hinge assembly 3, and the hinge assembly 3 can realize the relative rotation of the corresponding wall panels. By changing the angle between the corresponding wall panels, the cross-sectional shape of the overall hole tray is converted between a parallelogram (non-rectangular) and a rectangle. The shapes can be converted to each other to adapt to different seedling extraction methods and reduce the damage to the seedlings caused by the two different seedling extraction methods. During the conversion, the setting position of the drainage hole 201 must be ensured to correspond to each single hole tray 1. Compared with the traditional seedling cultivation hole tray, this hole tray is adaptable to the main seedling extraction methods on the market. During the seedling extraction process, the density change of the matrix is ​​more matched with the corresponding seedling extraction method, which improves the efficiency of the seedling extraction process and extracts the seedlings with lower losses.

[0018] like Figure 6 , Figure 7 As shown, the structure of the hinge assembly 3 is not limited, as long as it can ensure that when the two wall panels rotate relative to each other, no large gap will be generated between the two wall panels to leak the matrix, such as hinges, hinges and other hinged connection structures. Figure 7 As shown, the hinge assembly 3 consists 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 wall panel, and the second sleeve 302 is located on the side of the adjacent wall panel. The number of the second sleeves 302 is not less than one, and the optimal number is two, which are respectively arranged above and below the first sleeve 301, for example: the first sleeve 301 on the wall panel A 102 and the second sleeve 302 on the wall panel B 103. The embedded shaft 303 passes through the coaxially aligned first sleeve 301 and the second sleeve 302 to achieve relative rotation between the adjacent wall panels. The overall height of the first sleeve 301 and the second sleeve 302 is basically the same as the height of the wall panel, ensuring that the bottom of the hinge assembly 3 is in contact with the chassis 2. The embedded shaft 303 is connected to the hole tray wall panel and gives each single hole tray conversion activity when connected. The entire hole tray undergoes morphological transformation through the activity of the embedded shaft.

[0019] like Figure 5 As shown, the embedded shaft 303 at any vertex position of the integral plug tray extends and is inserted into the bottom plate 2 to fix the integral plug tray, and the remaining embedded shafts only serve as rotating shafts. Figure 2 , Figure 3 As shown, the embedded shaft 303 in the upper left corner serves as the fixed shaft 4, and the fixed shaft penetrates and is fixed to the bottom plate 2 at any of the four vertices of the entire hole tray. The overall hole tray is fixed in position by a fixed shaft, so as to meet the fixed connection between the overall hole tray and the bottom plate 2, and can also play a positioning role. After there is a fixed point, the deformation direction is limited to prevent excessive separation from the position during the deformation process due to the absence of a fixed point, and it is convenient for deformation force application.

[0020] 1. Plug tray conversion: (1) Insertion seedling retrieval is characterized by inserting tools into the substrate to grab the roots and substrate. The substrate is required to be loose. If the substrate is too tight, the tool will encounter resistance when inserted, resulting in damage to the root system or the seedling. A loose substrate can reduce the resistance to insertion, making the seedling retrieval process smoother and reducing damage to the seedling. Insertion seedling retrieval: It is more suitable when the density is 0.8-1.2g / cm3.

[0021] (2) The characteristic of top-out seedling extraction is that the seedlings are ejected from the bottom of the pot by applying an upward force. The density of the substrate is relatively high. A tighter substrate can better fix the seedlings and ensure the integrity of the roots and substrate during ejection. A too loose substrate may cause the seedlings to be unable to remain stable during ejection, and may even cause the roots to break or the seedlings to fall off. Top-out seedling extraction: It is more suitable when the density is 1.2-1.6g / cm3.

[0022] Therefore, according to different seedling removal methods, the density or looseness of the substrate does affect the effect of seedling removal and the integrity of the seedlings. In practical applications, choosing the appropriate density of the substrate can improve the efficiency and survival rate of seedling removal.

[0023] It is concluded that the insertion type seedling extraction is suitable for looser substrates and helps to reduce damage. The ejection type seedling extraction is suitable for tighter substrates and helps to maintain the integrity of the seedlings. Therefore, a plug tray device that can adjust the compactness of different substrates is proposed to better suit different seedling extraction methods.

[0024] According to the characteristics of area and volume changes in different graphic models, the area of ​​a parallelogram is: S=a(base)×h(height), the area of ​​a rectangle=a(base)×b(height), with the base length a fixed. When a parallelogram is transformed into a rectangle, its height (h) gradually becomes the height (b) of the rectangle. From the knowledge of triangles, we know that the hypotenuse is the longest in a triangle, so b>=h. At the same time, the height of the three-dimensional structure remains unchanged. Therefore, the volume gradually increases when a parallelogram is transformed into a rectangle. For seedling substrates of the same capacity, when the volume changes from large to small, it will tighten and the density will increase.

[0025] Structurally, in the square form of the single hole tray 1, the angles of the four sides are 90 degrees, the forces in all directions are relatively uniform, and the matrix can be loosely filled in each hole of the hole tray. Due to the regular shape, the distribution and filling of the matrix therein are relatively natural, the gaps between the matrix particles are larger, and the density is lower, which is conducive to inserting seedlings. At this time, the particles of the matrix can slide or adjust freely to reduce friction and damage to the roots of the seedlings. When converted to a parallelogram form, the change in the angle of the parallelogram will cause the matrix inside the single hole tray to be squeezed to a certain extent, especially along the direction of the shape change, the matrix particles that were originally regularly distributed are forcibly rearranged.

[0026] The transformation from a square to a parallelogram will change the internal structure of the plug tray. A square is a symmetrical shape, and the forces on the four corners are uniform. The matrix is ​​naturally loose in the plug tray. As the plug tray transforms into a parallelogram, the angle of the plug tray will change, generating greater lateral pressure. This deformation increases the extrusion of the matrix along the diagonal direction, resulting in a tighter arrangement of the matrix. During the morphological transformation process, the porosity in the matrix will decrease, the contact between the particles will increase, and the extrusion will slightly reduce the volume of the matrix and increase the density. At this time, the ejection type seedling can be used. For a looser matrix, the matrix is ​​looser and has better air permeability when it is a square. After the transformation to a parallelogram, the pores are compressed and the matrix becomes more compact. When the single plug tray 1 is restored from a parallelogram to a square, the extrusion force on the matrix is ​​reduced, and the originally extruded matrix particles will have more free space to readjust their positions and return to a loose state. The density of the matrix decreases, and the gaps between the particles increase, making the matrix looser. At this time, the inserted clamp pot can be used to remove the seedlings to reduce damage to the seedling root system.

[0027] The area of ​​the bottom plate 2 is larger than the bottom surface of all connected plug trays. During the conversion process, the shape and position of the bottom plate 2 remain unchanged. The single plug tray 1 is large enough, and the drainage hole 201 is small enough. Before and after the conversion, the position of the drainage hole 201 does not change much. The overall plug tray can be stretched from a plug tray with a rectangular top and bottom surface to a plug tray with a parallelogram top and bottom surface by the rotation axis. The internal volume of the single plug tray will change during the conversion, and the density of the matrix will also change through the change of volume capacity.

[0028] When cultivating the matrix, it can be solidified into a parallelogram first, and then converted into a rectangle when it is needed for plug tray transplanting. The plug tray will be loose and the density will be loose accordingly, which is suitable for inserting seedlings. On the contrary, if it is converted from a rectangle to a parallelogram, the volume will change from large to small, which is suitable for top-out seedlings.

[0029] The plug tray device provides a plug tray with parallelogram grids on the upper and lower openings, which is flexible and can be transformed into a plug tray with a rectangular upper and lower rectangular grid by embedding an axis, etc., so that the overall shape can be changed by changing the angle between cells without changing the cells themselves. A plug tray device is provided that can change the density of the matrix through morphological transformation, and the corresponding morphological transformation images correspond to different densities and corresponding seedling removal methods, thereby enhancing the low loss rate of the matrix after seedling removal.

[0030] 2. Reduce the adhesion of the tray wall: The wall plate is provided with a plurality of micropores 101 for drainage and preventing the passage of substrate particles. The application of micropore technology in the plug tray design is mainly to reduce the contact area between the substrate and the wall plate by creating tiny holes on the inner wall of the plug tray, thereby reducing adhesion. At the same time, the size of the micropores 101 needs to be carefully controlled to ensure that they are small enough to prevent the passage of substrate particles, but not too small to avoid affecting the air permeability and drainage of the plug tray. The microporous plug tray wall plate can enable the plug tray to achieve a more complex structure within a limited space, reduce the contact between the substrate and the wall plate, and reduce adhesion. In addition, the micropores can also provide better drainage and air permeability, which is conducive to the healthy growth of plant roots.

[0031] The specific usage process is as follows: Figure 1 , Figure 3 As shown, the two types of plug trays of the invention are fixed in such a way that the wall panels of the adjacent single plug trays 1 in the plug tray device are bonded and connected, and the fixing shaft penetrates and is fixed to the bottom plate at the top of the plug tray. The overall plug tray is fixed by a structure 1 fixing shaft to fix the plug tray position, so as to meet the fixed connection between the plug tray and the bottom plate. The four wall panels of each single plug tray 1 are connected by a hinge assembly 3. When culturing the matrix, first fix it as Figure 3 The parallelogram shape shown is then added to the matrix, and then holes are dug in the matrix to put in seeds. The density of the matrix can be used for top-out seedling removal. When the seedlings grow up and need to be transplanted, if the plug tray is used for the inserted seedling removal device, the plug tray is pushed to convert, and the shape of the plug tray changes through the hinge component 3. The plug tray is converted to Figure 1 Rectangular shape, the angles of the four sides are 90 degrees, the forces in all directions are relatively uniform, and the matrix can be loosely filled in each hole in the hole tray. Due to the regular shape, the distribution and filling of the matrix are relatively natural, the gaps between the matrix particles are relatively large, and the matrix is ​​naturally loose in the hole tray. At the same time, the volume capacity increases from small to large, and the density of the matrix decreases. This situation is suitable for the stem clamping and pot clamping insertion seedling removal method. After clamping the stem or pot, the mechanical claw clamps the seedlings upwards. The matrix is ​​relatively loose, and at the same time, due to the effect of the micropores 101, the contact between the matrix and the hole wall is reduced, which increases the drainage. It not only reduces the contact between the matrix and the wall panel and reduces the adhesion, but also makes it easier to clamp out and reduces the adhesion of the matrix to the wall panel. On the contrary, when culturing the matrix, first solidify it. Figure 1 A rectangular plug tray is added with a matrix, and then holes are dug in the matrix and seeds are put in. The density of the matrix can be used for inserting seedlings. When the seedlings grow up and need to be transplanted, if the plug tray is used for the ejection seedling device, the plug tray is pulled to convert, and the single plug tray changes shape through the hinge assembly 3. The whole plug tray is converted into Figure 3 Parallelogram morphology. As the overall hole tray transforms into a parallelogram morphology, the angle of a single hole tray will change, generating greater lateral pressure. This deformation increases the extrusion of the matrix along the diagonal direction, resulting in a tighter arrangement of the matrix. During the morphological transformation process, the porosity in the matrix will decrease, the contact between the particles will increase, and the extrusion effect will slightly reduce the volume of the matrix and increase the density. At the same time, the volume capacity decreases from large to small, and the density of the matrix increases. This situation is suitable for ejection seedling removal. The needle is pushed in from the drainage hole. Because the matrix is ​​more dense, the robustness of the matrix is ​​increased when it is ejected upward, and the degree of breakage is reduced during ejection. At the same time, due to the effect of the micropores 101, the contact between the matrix and the wallboard is reduced, and the drainage is increased. Not only does it reduce the contact between the matrix and the wallboard and reduce the adhesion, but it also appropriately reduces the humidity of the matrix and reduces the viscosity, making the ejection seedling removal more low-loss.

For researchers or technicians in this field, the present invention may have various changes and variations.
