Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a sowing device used for wheat breeding. Background Art

[0002] In order to cultivate excellent wheat varieties with the characteristics of high yield, high quality and strong stress resistance, it is usually necessary to conduct various tests on individual hydroponic wheat seedlings to evaluate their genetic characteristics and adaptability to specific environments. After the wheat seedlings complete specific tests in the culture room, in order to continue to observe the growth of the wheat seedlings under conditions closer to nature, the wheat seedlings need to be transplanted to the field to evaluate the field performance of the variety. When transplanting existing wheat seedlings, it is usually necessary to manually separate the wheat seedlings from the culture tube. For hydroponic wheat seedlings containing perlite, in order to help the seedlings adapt to the new soil faster, the perlite at the roots of the wheat seedlings usually needs to be transplanted together with the wheat seedlings. During the separation of wheat seedlings, it is difficult for humans to control the strength during separation, which can easily cause squeezing and pulling on the roots of the wheat seedlings, thereby damaging the roots of some wheat seedlings, affecting the later growth of the wheat seedlings, resulting in inaccurate test data, and low manual work efficiency. The separated wheat seedlings are not protected, and long transplant waiting times will weaken their growth potential and adaptability to the new environment. Summary of the invention

[0003] In order to overcome the disadvantage that the force cannot be controlled when manually separating the wheat seedlings and the culture bottles, which easily causes squeezing and pulling on the roots of the wheat seedlings, thereby damaging the roots of some wheat seedlings, affecting the later growth of the wheat seedlings, and causing inaccurate test data, the present invention provides a sowing device for wheat breeding.

[0014] Beneficial effects of the present invention: The present invention realizes squeezing the perlite through the squeezing ring, so that the block is gradually turned over and is in an open state, thereby preventing the wheat seedlings from being directly contacted with the roots when the wheat seedlings are manually separated from the culture cylinder, causing squeezing of the roots of the wheat seedlings, resulting in damage and affecting the reliability of the test data; The pressing block is used to squeeze the pressed block, so that the stopper is actively turned over, and at the same time, the squeezing ring inside the culture tube moves downward to squeeze the perlite in the culture tube, thereby improving the separation efficiency of the wheat seedlings and the culture tube, and preventing the squeezing ring from squeezing downward to cause pressure on the roots of the wheat seedlings and causing damage; The outer edge of each extrusion ring is always in contact with the inner wall of the culture tube, so that when the extrusion ring moves downward in the culture tube, the inner wall of the culture tube is scraped, thereby preventing part of the perlite from adhering to the inner wall of the culture tube and avoiding additional cleaning work of the culture tube at a later stage; The two arc-shaped pieces at the bottom of the puncher are combined in an upward convex state to squeeze and guide the perlite at the root of the wheat seedlings, so that the perlite is dispersed around, reducing the bulge range of the root of the wheat seedlings, preventing the burial depth of the root of the wheat seedlings from being affected when the puncher is opened, and improving the accuracy of the data; By setting the reed in a downward curved shape, when the puncher is opened, the perlite scattered in the puncher is guided downward, so that the perlite slides down the arc surface of the reed into the soil, thereby preventing the perlite from getting stuck in the puncher and affecting the subsequent normal transplanting of wheat seedlings.

[0019] Furthermore, in order to prevent the roots of the wheat seeds from growing to one side due to their tendency to hydrophilize during the subsequent growth process, the water inlet holes 3001 on the lower side of each culture tube 3 are distributed in a ring shape.

[0020] Furthermore, in order to prevent the perlite from passing through the water inlet hole 3001 and falling to the outside of the culture tube 3, a filter net 3002 is provided on the water inlet hole 3001 on the lower side of each culture tube 3.

[0021] Furthermore, in order to prevent the wheat seedling growth data from being confused and affecting the reliability of the test, a card slot 3003 is provided on each culture tube 3.

[0022] The connecting assembly includes a connecting plate 105, a connecting rod 106 and an elastic member 107; each culture tube 3 is slidably connected to two left-right symmetrical connecting plates 105; a connecting rod 106 is fixedly connected to the lower side of each connecting plate 105, and the extrusion ring 4 is fixedly connected to two adjacent connecting rods 106; an elastic member 107 is fixedly connected between each connecting plate 105 and the culture tube 3, and the elastic member 107 is a spring.

[0023] The first driving assembly includes an electric crawler 101, a connecting block 102, and the electric crawler 101 is fixedly connected to the transplanter 1; each culture tube 3 is provided with a protrusion; a plurality of connecting blocks 102 are fixedly connected to the electric crawler 101, each connecting block 102 is provided with a placement groove, and the protrusion on the culture tube 3 is embedded in the placement groove of the connecting block 102.

[0024] The second driving assembly includes a first driving member 103 and a fixed plate 104; two left-right symmetrical first driving members 103 are fixedly connected to the transplanter 1, and the first driving member 103 is an electric push rod; each first driving member 103 output end is fixedly connected to a fixed plate 104, and each extrusion block 6 is fixedly connected to an adjacent fixed plate 104, and the fixed plate 104 and the extrusion block 6 are driven by the first driving member 103 to move up and down.

[0025] The working steps of this embodiment are: The first step is to place the culture tube 3 in the culture room, and evenly sprinkle an appropriate amount of hydroponic media such as perlite in the culture tube 3, and hold the perlite through the block 5, and then place a single wheat seed on the perlite in the culture tube 3, and then fix the culture tube 3 at equal intervals according to the hydroponic requirements of a single wheat plant, and then introduce water into the culture tube 3. At this time, the water flows into the culture tube 3 through the water inlet hole 3001 of the culture tube 3 until the water contacts the bottom of the seed and does not submerge the seed. The water flows in a circular array on the lower side of the culture tube 3 through the water inlet hole 3001, so that the water flows evenly from the outside of the culture tube 3 into the inside of the culture tube 3, thereby preventing the roots of the wheat seeds from growing to one side due to their hydrophilicity in the subsequent growth process, thereby avoiding affecting the growth of the wheat seedlings. At the same time, the perlite is intercepted by the filter net 3002 on the water inlet hole 3001 to prevent the perlite from passing through the water inlet hole 3001 and falling to the outside of the culture tube 3, thereby affecting the normal growth of the wheat seedlings.

[0026] In the second step, after the wheat seeds germinate and grow into seedlings, the wheat seedlings are subjected to various tests such as lodging resistance according to research needs. The tests are used to evaluate the growth performance of different wheat varieties or genotypes under specific hydroponic conditions. The growth of wheat seedlings after the tests is different. The corresponding growth conditions of the wheat seedlings are then recorded on a card, and the card is then placed in the card slot 3003 of the corresponding culture tube 3 to prevent confusion in the wheat seedling growth data and affect the reliability of the test.

[0027] In the third step, after the wheat seedlings have completed specific tests in the culture room, in order to continue to observe the growth of the wheat seedlings under conditions closer to nature, the wheat seedlings need to be transplanted to the field to evaluate the field performance of the variety. When the existing wheat seedlings are transplanted, the wheat seedlings usually need to be separated from the culture tube 3. For the hydroponic wheat seedlings containing perlite, in order to help the seedlings adapt to the new soil faster, the perlite at the roots of the wheat seedlings usually needs to be transplanted together with the wheat seedlings. During the separation of the wheat seedlings, it is difficult for humans to control the strength during separation, which can easily cause squeezing and pulling on the roots of the wheat seedlings, thereby damaging the roots of some wheat seedlings, affecting the later growth of the wheat seedlings, resulting in inaccurate test data, and low manual work efficiency. The separated wheat seedlings are not protected, and the long transplant waiting time will weaken their growth potential and adaptability to the new environment.

[0028] The fourth step is to first transfer the culture tube 3 together with the wheat seedlings to the outdoor transplanter 1 during transplantation, so that the protrusions of each culture tube 3 are correspondingly inserted into the placement grooves on the connecting block 102 of the electric crawler 101, thereby completing the fixation of the culture tube 3.

[0029] The fifth step, taking the discharge port 1001 on the left side of the transplanter 1 as an example, the transplanter 1 is then started, and the electric crawler 101 is controlled to rotate by the control host 2, thereby driving the culture tube 3 to perform circular motion. When the electric crawler 101 drives the culture tube 3 to move above the discharge port 1001 of the transplanter 1, the puncher 7 is controlled by the control host 2 to move up and down and open and close to achieve the transplanting of wheat seedlings. When the puncher 7 gradually approaches the discharge port 1001 from below, the first driving member 103 is then controlled to drive the fixed plate 104 and the extrusion block 6 to approach the adjacent connecting plate 105, and the extrusion block 6 squeezes the upper side of the connecting plate 105, so that the elastic member 107 gradually contracts, thereby driving the connecting plate 105 and the connecting rod 10 6 and the extrusion ring 4 move downward, at which time the extrusion ring 4 gradually contacts the perlite below and continues to extrude the perlite. At the same time, the block 5 on the lower side of the perlite is squeezed by the perlite and flipped outward until the block 5 is fully opened, so that the wheat seedlings and the perlite fall from the culture tube 3 into the puncher 7 below, thereby completing the separation of the wheat seedlings from the culture tube 3, and squeezing the perlite through the extrusion ring 4, so that the block 5 gradually flips and opens. At this time, the wheat seedlings and the perlite will fall together into the puncher 7 below, thereby preventing the wheat seedlings from being directly contacted with the roots of the wheat seedlings when the wheat seedlings are separated from the culture tube 3 manually, causing squeezing of the roots of the wheat seedlings, resulting in damage, and affecting the reliability of the test data.

[0030] In the sixth step, after the wheat seedlings fall into the puncher 7, the puncher 7 is controlled to move downward by controlling the host 2 until the puncher 7 makes a hole in the soil. The puncher 7 is then opened and moves upward again to make the wheat seedlings fall into the hole. Then, the two rollers 8 located behind the puncher 7 push the soil on the left and right sides of the hole to make the soil gather towards the wheat seedlings, thereby completing the burial of the roots of the wheat seedlings wrapped with perlite, thereby realizing the transplanting of the wheat seedlings. Example 2

[0031] On the basis of Example 1, Figure 1 , Figure 2 and Figure 5As shown, the protective component includes a second driving member 201, a pressing block 202 and a pressure block 203; four second driving members 201 are fixedly connected to the transplanter 1, and the second driving member 201 is an electric push rod; the output end of each second driving member 201 is fixedly connected to a pressing block 202; two pressure blocks 203 are arranged on the lower side of each culture cylinder 3, and each pressure block 203 is fixedly connected to the adjacent stop block 5.

[0032] Furthermore, in order to prevent part of the perlite from adhering to the inner wall of the culture tube 3 , the outer edge of each extrusion ring 4 is always in contact with the inner wall of the culture tube 3 .

[0033] The working principle of this embodiment is: In the fifth step of Example 1: During the cultivation of wheat seedlings, some of the wheat seedlings have lush root systems. Therefore, when the wheat seedlings are separated from the culture tube 3, their roots are tightly adhered to the culture tube 3, resulting in that when the extrusion ring 4 squeezes the perlite, it is difficult to push the lower block 5 outward, so that the perlite oppresses the roots of the wheat seedlings, causing damage and affecting the subsequent normal growth of the wheat seedlings.

[0034] To solve the above situation, when the extrusion block 6 squeezes the upper side of the connecting plate 105, the second driving member 201 is controlled to drive the adjacent pressing block 202 to move upward until the pressing block 202 squeezes the pressed block 203. At the same time, after the pressed block 203 is squeezed, it will drive the adjacent block 5 to flip, so that the block 5 actively flips, and at the same time cooperates with the extrusion ring 4 inside the culture tube 3 to move downward to squeeze the perlite in the culture tube 3, thereby improving the separation efficiency of the wheat seedlings and the culture tube 3, and preventing the extrusion ring 4 from causing pressure on the roots of the wheat seedlings when squeezing downward, causing damage. By making the outer edge of each extrusion ring 4 always fit with the inner wall of the culture tube 3, the extrusion ring 4 can scrape the inner wall of the culture tube 3 when moving downward in the culture tube 3, thereby preventing part of the perlite from adhering to the inner wall of the culture tube 3 and avoiding increasing the cleaning work of the culture tube 3 in the later stage. Example 3

[0035] On the basis of Example 1, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes an arc-shaped piece 301; each puncher 7 is fixedly connected to two left-right symmetrical arc-shaped pieces 301 on the lower side; two adjacent arc-shaped pieces 301 are combined to be in an upward convex state.

[0036] It also includes a reed 302; a reed 302 is fixedly connected to the middle of each arc-shaped piece 301, and the reed 302 is initially bent downward, and the combination of two adjacent reeds 302 is concave downward; a convex portion 30201 is provided on the lower side of each reed 302.

[0037] Each arc-shaped piece 301 is made of elastic deformable material.

[0038] The working principle of this embodiment is: In the sixth step of Example 1: when the wheat seedlings fall into the puncher 7, the puncher 7 is in a closed state, and the two arc-shaped pieces 301 at the bottom of the puncher 7 are combined to be in an upwardly convex state, so that the perlite at the root of the wheat seedlings is squeezed and guided, so that the perlite is dispersed around, reducing the bulge range of the root of the wheat seedlings, preventing the puncher 7 from affecting the burial depth of the root of the wheat seedlings when it is opened, and improving the accuracy of the data.

[0039] When the punch 7 is gradually closed from an open state, the convex portion 30201 of the left reed 302 will be squeezed against the convex portion 30201 of the right reed 302. As the punch 7 is closed, the two reeds 302 are squeezed and gradually deformed, so that the arc-shaped piece 301 is convex upward, thereby squeezing and guiding the perlite at the root of the wheat seedlings to disperse the perlite to the surroundings. When the punch 7 is gradually opened from a closed state, the convex portions 30201 of the left and right reeds 302 are gradually separated. At this time, the reed 302 gradually rebounds and resets and bends downward. By setting the reed 302 to be bent downward, when the punch 7 is opened, the perlite scattered in the punch 7 is guided downward, so that the perlite slides down along the arc surface of the reed 302 into the soil, thereby preventing the perlite from being stuck in the punch 7 and affecting the normal transplanting of the subsequent wheat seedlings.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes 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.
