Description

Technical Field

[0001] This utility model relates to the field of seedling propagation technology of Chinese medicinal plants, and in particular to the dovetail tenon and mortise type hard film fixing structure for Paris polyphylla seedling cultivation used in the process of cultivating Yunnan Paris polyphylla seedlings. Background Technology

[0002] Yunnan Paris polyphylla is a perennial herb belonging to the genus Paris of the Liliaceae family. It possesses properties such as clearing heat and detoxifying, reducing swelling and relieving pain, and is commonly used to treat various ailments. However, due to its long growth cycle of 8-10 years and slow natural growth rate, its demand from traditional Chinese medicine manufacturers has surged in recent years, leading to a significant increase in purchase prices. This has fueled farmers' enthusiasm for harvesting, resulting in a harvesting rate far exceeding the natural growth rate. Consequently, wild Yunnan Paris polyphylla resources are scarce, threatening its sustainable utilization and the stable development of the traditional Chinese medicine industry.

[0003] To alleviate pressure on wild resources, people have begun to explore artificial cultivation techniques for Paris polyphylla in Yunnan. Currently, production mainly uses propagation by cuttings with terminal buds and seed propagation, with field seedling cultivation being a key step. This technique generally involves raising seedlings first and then transplanting them. During seedling cultivation, the seedbed surface is prepared, seeds are evenly sown, covered with loose and breathable substrate soil and well-rotted sawdust, thoroughly watered, and then covered with a thick black plastic film (about 0.5 mm thick), with bamboo sticks or thin wooden sticks inserted into the soil along the edges to secure it.

[0004] However, this traditional fixing method has obvious drawbacks. During strong winds or rainy seasons, the plastic film fixed by bamboo sticks or thin wooden sticks is easily torn by external forces, exposing the soil surface to waterlogging and other disasters, leading to an unstable soil environment, affecting the normal development of seedlings, and reducing the survival rate and quality of seedlings.

[0005] Therefore, there is an urgent need for a stable and durable plastic film fixing structure, which is of great significance for improving the survival rate and quality of Yunnan Paris polyphylla seedlings and promoting the application of artificial cultivation technology. Utility Model Content

[0006] This invention provides a dovetail tenon-and-mortise type rigid film fixing structure for Paris polyphylla seedlings, which can be quickly fixed, is sturdy and durable, and will not be blown away or torn by the wind after being covered, in order to solve the problems existing in the above-mentioned background technology.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A dovetail tenon and mortise type rigid film fixing structure for Paris polyphylla seedlings includes a tenon strip and a mortise strip. The tenon strip and the mortise strip are connected to form a tenon and mortise body. A positioning component is installed on the tenon strip. The tenon strip and the mortise strip are limited and fixed by the positioning component. After the tenon strip and the mortise strip are engaged, they are fixed to the ground by a fixing rod.

[0008] Furthermore, the positioning component includes a push rod, a connecting block is fixedly connected to the push rod, the connecting block is rotatably connected to one end of the connecting rod, and a slider is rotatably connected to the other end of the connecting rod. Two sets of push rods and connecting blocks are provided, located on symmetrical sides of the slider respectively. A return spring is provided at the top of the slider, and a limit rod is fixed at the bottom of the slider.

One end of the return spring is fixedly connected to the inner wall of the installation cavity, and the other end is fixedly connected to the top of the slider. The limiting rod is slidably connected to the sliding groove I and passes through the bottom of the tenon strip.

[0010] Furthermore, the mortise strip has an arc-shaped groove in the mortise groove, and the limiting rod has an arc-shaped part at one end of the tenon strip. In the mortise and tenon body, when the limiting rod is in the initial position, its arc-shaped part abuts against the arc-shaped groove under the action of the return spring.

[0011] Furthermore, two grooves are symmetrically formed above the tenon strip, and the two push rods extend out of the mounting cavity and are slidably connected thereto. A push block is fixedly connected to one end of each push rod extending out of the mounting cavity, and the two push blocks are located in the grooves.

[0012] Furthermore, the fixing rod is an L-shaped rod, with the horizontal and vertical bars of the L-shaped rod respectively abutting against the top surface and one side of the tenon and mortise body to fix the tenon and mortise body to the ground.

[0013] Furthermore, a snap-fit ​​block is provided at the end of the L-shaped crossbar away from the vertical bar, and the snap-fit ​​block snaps into the inner wall of the groove.

[0014] Furthermore, the fixing rod is provided with a spike.

[0015] Furthermore, a gap is left at the connection between the tenon strip and the mortise strip for installing and fixing the plastic film.

[0016] This utility model has the following beneficial effects: (1) The dovetail tenon and mortise connection method of this utility model makes the tenon strip, the mortise strip and the plastic film fit together tightly, and the connection stability is further enhanced by the positioning component for limiting and fixing. At the same time, the tenon body is fixed to the ground by the fixing rod, the horizontal bar and the vertical bar of the L-shaped rod abut against the top surface and one side of the tenon body respectively, and the spike is inserted into the ground, so that the plastic film can remain stable in harsh environments such as strong winds and rainy seasons, effectively preventing the plastic film from being torn or damaged, and providing reliable protection for Paris polyphylla seedling cultivation.

[0017] (2) The design of the positioning component makes it easy to install and disassemble the tenon strip and the mortise strip; by pushing the push block to move the push rod, the connecting rod moves the slider, and the limiting rod disengages from the arc groove, the tenon strip and the mortise strip can be separated; when it is necessary to replace the plastic film or perform other operations, the operation can be carried out quickly and conveniently, which improves work efficiency.

[0018] (3) The snap-fit ​​block on the fixing rod of this utility model allows the snap-fit ​​block to snap into the inner wall of the groove after the fixing rod is fixed to the tenon body, which further enhances the stability of the connection between the fixing rod and the tenon body.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] A dovetail tenon-and-mortise type rigid film fixing structure for Paris polyphylla seedling cultivation, as shown in the attached figure. Figure 1-4 As shown, it includes a tenon strip 1 and a mortise strip 2. The tenon strip 1 and the mortise strip 2 are connected to form a tenon and mortise body. A gap is left at the connection between the tenon strip 1 and the mortise strip 2 for installing and fixing the plastic film. In actual use, multiple tenon and mortise bodies can be set adjacent to each other. A positioning component is installed on the tenon strip 1. The tenon strip 1 and the mortise strip 2 are limited and fixed by the positioning component. After the tenon strip 1 and the mortise strip 2 are engaged, they are fixed to the ground by a fixing rod 3.

[0022] Specifically, the positioning component includes a push rod 4, a connecting block 5 fixedly connected to the push rod 4, a connecting block 5 rotatably connected to one end of a connecting rod 6, and a slider 7 rotatably connected to the other end of the connecting rod 6. Two sets of push rods 4 and connecting blocks 5 are provided, located on symmetrical sides of the slider 7 respectively. A return spring 8 is provided at the top of the slider 7, and a limiting rod 9 is fixed at the bottom of the slider 7.

[0023] Specifically, an installation cavity 10 is provided inside the upper part of the tenon strip 1. A sliding groove I11 is provided in the vertical direction of the installation cavity 10, which is slidably connected to the connecting block 5. A sliding groove II12 is also provided in the installation cavity 10, which is slidably connected to the slider 7. The sliding groove II12 is perpendicular to the sliding groove I11. One end of the return spring 8 is fixedly connected to the inner wall of the installation cavity 10, and the other end is fixedly connected to the top of the slider 7. The limiting rod 9 is slidably connected to the sliding groove I11 and passes through the bottom of the tenon strip 1.

[0024] Specifically, the mortise 13 of the tenon strip 2 is provided with an arc-shaped groove 14, and the limiting rod 9 is provided with an arc-shaped part 15 extending out of the tenon strip 1. In the mortise and tenon body, when the limiting rod 9 is in the initial position, its arc-shaped part 15 abuts against the arc-shaped groove 14 under the action of the return spring 8. The abutment between the arc-shaped part and the arc-shaped groove in the positioning component can, on the one hand, prevent the tenon strip and the mortise strip from sliding relative to each other during use, and on the other hand, prevent the plastic film from sliding and shifting, thereby affecting the use effect.

[0025] Furthermore, to facilitate the operation of the positioning component, two grooves 17 are symmetrically provided above the tenon strip 1. Both push rods 4 extend out of the mounting cavity 10 and are slidably connected thereto. One end of each push rod 4 extending out of the mounting cavity 10 is fixedly connected to a push block 16. Both push blocks 16 are located in the grooves 17.

[0026] Specifically, the fixing rod 3 is an L-shaped rod, and the horizontal and vertical bars of the L-shaped rod abut against the top surface and one side of the tenon body respectively to fix the tenon body to the ground.

[0027] Furthermore, in order to better fix the fixing rod 3 to the tenon body, a snap-fit ​​block 18 is provided at the end of the L-shaped rod away from the vertical rod, and the snap-fit ​​block 18 is snapped into the inner wall of the groove 17; the fixing rod 3 is provided with a spike 19.

[0028] Example 1

[0029] Fixing the plastic film: First, place the edge of the plastic film to be fixed into the mortise groove 13 of the mortise strip 2. Slide the tenon strip 1 and the mortise strip 2 together to fix the plastic film in the gap between the mortise strip 2 and the tenon strip 1. During this process, when it slides to the position of the arc groove 14 on the mortise groove, the push rod 4 can be slid inward along the slide groove II 12 by pinching the two push blocks 16. The connecting rod 6 pushes the connecting block 5 to move upward along the slide groove I 11, so that the limiting rod 9 moves upward and retracts back into the slide groove I 11. When the tenon strip 1 and the mortise strip 2 reach the limited position, release the push block 16. At this time, the return spring 8 returns to its original position and pushes the limiting rod 9 downward, so that the arc part 15 abuts against the arc groove 14. At the same time, the tenon and mortise strip 1 and the mortise strip 2 are fixed by the fixing rod 3 and fixed by the spike 19 inserted into the ground.

[0030] Example 2

[0031] Removal of the plastic film: First, the fixing rod 3 is removed manually to separate the fixing rod 3 from the tenon body. The two push blocks 16 are pinched together, and the tenon strip 1 and the mortise strip 2 are slid in opposite directions to separate them (the movement process of the positioning component during the separation process is the same as in Example 1, and will not be described again here). After the separation is completed, the plastic film is removed and stored for future use.
