Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery, in particular to a seeding device for wheat breeding. BACKGROUND

[0002] In order to cultivate excellent wheat varieties with high yield, high quality, strong stress resistance and other characteristics, it is usually necessary to test single plant hydroponic wheat seedlings to evaluate their genetic characteristics and adaptability to specific environments. When the wheat seedlings complete specific tests in the culture room, it is necessary to transplant the wheat seedlings to the field to continue to observe the growth of the wheat seedlings under conditions closer to nature, so as to evaluate the field performance of the varieties. When the existing wheat seedlings are transplanted, the wheat seedlings are usually separated from the culture cylinder by manual operation. For hydroponic wheat seedlings containing perlite, in order to help the seedlings adapt to the new soil faster, the perlite at the root of the wheat seedling is usually transplanted together with the wheat seedling. During the separation of the wheat seedlings, the manual operation cannot control the force during the separation, which is easy to cause extrusion and pulling of the roots of the wheat seedlings, thereby damaging the roots of part of the wheat seedlings and affecting the growth of the wheat seedlings in the later period, resulting in inaccurate test data. The manual work efficiency is low, and the separated wheat seedlings are not protected. Long waiting time for transplantation will weaken the growth potential and adaptability to the new environment.

[0029] It also includes a first drive assembly, culture cylinders 3, connecting assemblies, extrusion rings 4, stop blocks 5, a second drive assembly, extrusion blocks 6, and a protective assembly; the transplanter 1 is equipped with the first drive assembly; eight culture cylinders 3 are connected to the first drive assembly, which drives the culture cylinders 3 to perform circular motion; each culture cylinder 3 has four water inlets 3001 on its lower side; each culture cylinder 3 is equipped with a connecting assembly; the connecting assembly is connected to the extrusion ring 4; each culture cylinder 3 has two symmetrical stop blocks 5 rotatably connected to its lower side by a torsion spring; the transplanter 1 is equipped with the second drive assembly; two symmetrical extrusion blocks 6 are connected to the second drive assembly, which drives the extrusion blocks 6 to move up and down; the transplanter 1 is equipped with a protective assembly.

[0030] Furthermore, to prevent the wheat seed roots from growing to one side due to hydrotropism during subsequent growth, the water inlet holes 3001 on the lower side of each culture tube 3 are arranged in a ring.

[0031] Furthermore, to prevent perlite from falling through the water inlet hole 3001 to the outside of the culture tube 3, a filter screen 3002 is installed on the water inlet hole 3001 on the lower side of each culture tube 3.

[0032] Furthermore, to prevent confusion in wheat seedling growth data and affect the reliability of the experiment, each culture tube 3 is equipped with a slot 3003.

[0033] The connecting assembly includes a connecting plate 105, a connecting rod 106, and an elastic element 107; two symmetrical connecting plates 105 are slidably connected to each culture tube 3; a connecting rod 106 is fixedly connected to the lower side of each connecting plate 105, and the compression ring 4 is fixedly connected to the two adjacent connecting rods 106; an elastic element 107 is fixedly connected between each connecting plate 105 and the culture tube 3, and the elastic element 107 is a spring.

[0034] The first drive assembly includes an electric track 101, a connecting block 102, and an electric track 101 fixedly connected to the transplanter 1; each culture cylinder 3 is provided with a protrusion; a number of connecting blocks 102 are fixedly connected to the electric track 101, each connecting block 102 is provided with a placement groove, and the protrusion on the culture cylinder 3 is engaged with the placement groove of the connecting block 102.

[0035] The second drive assembly includes a first drive member 103 and a fixed plate 104; two left-right symmetrical first drive members 103 are fixedly connected to the transplanter 1, and the first drive member 103 is an electric push rod; the output end of each first drive member 103 is fixedly connected to a fixed plate 104, and each extrusion block 6 is fixedly connected to the adjacent fixed plate 104, and the fixed plate 104 and the extrusion block 6 are driven to move up and down by the first drive member 103.

[0036] The working steps of this embodiment are as follows:

[0037] The first step is to place the culture tube 3 in the culture room and evenly sprinkle an appropriate amount of hydroponic medium, such as perlite, into the culture tube 3. The perlite is then held in place by the baffle 5. Next, a single wheat seed is placed on the perlite in the culture tube 3. Then, according to the requirements of single-plant hydroponics, the culture tubes 3 are fixed at equal intervals. Water is then introduced into the culture tube 3. The water flows into the culture tube 3 through the water inlet 3001 until it reaches the bottom of the seed without submerging it. The water inlet 3001 forms a circular array on the lower side of the culture tube 3, so that the water flows evenly from the outside of the culture tube 3 into the inside. This prevents the wheat seed roots from growing to one side due to hydrotropism during subsequent growth, thus avoiding affecting the growth of the wheat seedlings. At the same time, the perlite is intercepted by the filter screen 3002 on the water inlet 3001, preventing it from falling through the water inlet 3001 to the outside of the culture tube 3 and affecting the normal growth of the wheat seedlings.

[0038] The second step is to conduct various tests on the wheat seedlings, such as lodging resistance, according to the research needs. These tests are used to evaluate the growth performance of different wheat varieties or genotypes under specific hydroponic conditions. The growth of the wheat seedlings after the tests will vary. The growth conditions of the wheat seedlings will then be recorded on cards and placed in the slots 3003 of the corresponding culture tube 3 to prevent the wheat seedling growth data from being confused and affecting the reliability of the experiment.

[0039] The third step involves transplanting wheat seedlings to the field after specific tests are completed in the culture chamber. To further observe their growth under more natural conditions, the seedlings need to be transplanted to assess their field performance. Transplanting existing wheat seedlings typically requires separating them from the culture container 3. For hydroponic wheat seedlings containing perlite, to help the seedlings adapt to the new soil more quickly, the perlite around the roots is usually transplanted along with the seedlings. However, during the separation process, manual separation is difficult to control, easily causing pressure and pulling on the roots, damaging some roots and affecting later growth. This leads to inaccurate experimental data, low efficiency, and lack of protection for the separated seedlings. Prolonged waiting after transplanting weakens their growth potential and adaptability to the new environment.

[0040] The fourth step is to transfer the culture cylinder 3 along with the wheat seedlings to the outdoor transplanter 1, so that the protrusions of each culture cylinder 3 are inserted into the placement grooves on the connecting block 102 of the electric track 101, thereby completing the fixation of the culture cylinder 3.

[0041] Fifth, taking the feed inlet 1001 on the left side of the transplanter 1 as an example, the transplanter 1 is then started. The electric track 101 is rotated by the control host 2, thereby driving the cultivation cylinder 3 to move in a circular motion. When the electric track 101 drives the cultivation cylinder 3 to move above the feed inlet 1001 of the transplanter 1, the hole punch 7 is moved up and down and opened and closed by the control host 2 to realize the transplanting of wheat seedlings. As the hole punch 7 gradually approaches the feed inlet 1001 from below, the first driving component 103 is controlled to drive the fixed plate 104 and the extrusion block 6 to move closer to the adjacent connecting plate 105, and the extrusion block 6 extrudes the upper side of the connecting plate 105, causing the elastic component 107 to gradually contract, thereby driving the connecting plate 105 and the connecting rod 10 6. The extrusion ring 4 moves downward, gradually contacting the perlite below and continuously extruding it. Simultaneously, the block 5 on the lower side of the perlite is extruded by the perlite and flips outward until it is fully open. This allows the wheat seedlings and perlite to fall from the culture tube 3 into the perforator 7 below, thus separating the wheat seedlings from the culture tube 3. By extruding the perlite with the extrusion ring 4, the block 5 gradually flips and opens, allowing the wheat seedlings and perlite to fall together into the perforator 7 below. This prevents direct contact with the roots of the wheat seedlings during manual separation from the culture tube 3, which could cause damage and affect the reliability of the experimental data.

[0042] The sixth step involves controlling the hole punch 7 to move downwards after the wheat seedlings fall into the hole punch 7. The hole punch 7 is then moved upwards again by the control unit 2 until it makes a hole in the soil. The hole punch 7 then opens and moves upwards again, causing the wheat seedlings to fall into the hole. The two rollers 8 located behind the hole punch 7 then push the soil on both sides of the hole, causing the soil to converge towards the wheat seedlings. This completes the burial of the roots of the wheat seedlings wrapped in perlite, thus achieving the transplanting of the wheat seedlings. Example 2

[0043] Based on Example 1, such as Figure 1 , Figure 2 and Figure 5 As shown, the protective assembly includes a second driving component 201, a pressing block 202, and a pressure-receiving block 203; four second driving components 201 are fixedly connected to the transplanter 1, and the second driving components 201 are electric push rods; the output end of each second driving component 201 is fixedly connected to a pressing block 202; two pressure-receiving blocks 203 are provided on the lower side of each culture tube 3, and each pressure-receiving block 203 is fixedly connected to the adjacent stop block 5.

[0044] Furthermore, to prevent some perlite from adhering to the inner wall of the culture cylinder 3, the outer edge of each extrusion ring 4 is always in contact with the inner wall of the culture cylinder 3.

[0045] The working principle of this embodiment is as follows:

[0046] In the fifth step of Example 1: During the cultivation of wheat seedlings, some wheat seedlings have vigorous root growth. Therefore, when the wheat seedlings are separated from the culture tube 3, their roots are tightly adhered to the culture tube 3. This makes it difficult for the compression ring 4 to push the lower block 5 outward when it squeezes the perlite. As a result, the perlite compresses the wheat seedling roots, causing damage and affecting the normal growth of the wheat seedlings.

[0047] To address the above issues, when the extrusion block 6 presses against the upper side of the connecting plate 105, the second driving component 201 is controlled to move the adjacent pressing block 202 upwards until the pressing block 202 presses against the pressure block 203. Simultaneously, after being pressed, the pressure block 203 will cause the adjacent stop block 5 to flip, thus causing the stop block 5 to actively flip. At the same time, the extrusion ring 4 inside the culture cylinder 3 moves downwards to extrude perlite inside the culture cylinder 3, improving the separation efficiency between the wheat seedlings and the culture cylinder 3. This also prevents the extrusion ring 4 from pressing down on the roots of the wheat seedlings, causing damage. Since the outer edge of each extrusion ring 4 is always in contact with the inner wall of the culture cylinder 3, the extrusion ring 4 scrapes the inner wall of the culture cylinder 3 as it moves downwards, thus preventing some perlite from adhering to the inner wall of the culture cylinder 3 and avoiding additional cleaning work for the culture cylinder 3 later. Example 3

[0048] Based on Example 1, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes an arc-shaped piece 301; two symmetrical arc-shaped pieces 301 are fixed to the lower side of each punch 7; the two adjacent arc-shaped pieces 301 are combined to form an upward convex state.

[0049] It also includes a spring 302; a spring 302 is fixedly connected to the middle of each arc-shaped piece 301, and the spring 302 is initially bent downwards, and two adjacent springs 302 are combined to form a downward concave shape; a protrusion 30201 is provided on the lower side of each spring 302.

[0050] Each arc-shaped piece 301 is made of an elastic deformation material.

[0051] The working principle of this embodiment is as follows:

[0052] In the sixth step of Example 1: when the wheat seedling falls into the hole punch 7, the hole punch 7 is in the closed state. The two arc-shaped pieces 301 at the bottom of the hole punch 7 are combined to form an upward convex state, which squeezes and guides the perlite at the root of the wheat seedling, causing the perlite to disperse in all directions, reducing the bulging range of the wheat seedling root, preventing the hole punch 7 from affecting the burial depth of the wheat seedling root when it is opened, and improving the accuracy of the data.

[0053] As the hole punch 7 gradually closes from the open state, the protrusion 30201 of the left spring 302 will press against the protrusion 30201 of the right spring 302. As the hole punch 7 closes, the two springs 302 are gradually deformed under pressure, causing the arc-shaped piece 301 to bulge upwards, thereby squeezing and guiding the perlite at the roots of the wheat seedlings, causing the perlite to disperse in all directions. As the hole punch 7 gradually opens from the closed state, the protrusions 30201 of the left and right springs 302 gradually separate. At this time, the springs 302 gradually spring back to their original position and bend downwards. By setting the springs 302 to bend downwards, when the hole punch 7 opens, the perlite scattered in the hole punch 7 is guided downwards, allowing the perlite to slide down along the arc surface of the spring 302 into the soil, thereby preventing the perlite from getting stuck in the hole punch 7 and affecting the normal transplanting of the wheat seedlings.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
