Description

Technical Field

[0001] The present invention relates to the technical field of seed breeding and seedling cultivation, in particular to a novel agricultural breeding device. Background Art

[0002] In the field of agricultural breeding, the traditional hydroponic germination method requires manual removal of the entire tray of seeds and then picking out the germinated individuals. The operation is cumbersome and it is easy to expose the ungerminated seeds to the air, resulting in a decrease in the overall germination rate. In other words, germinated and ungerminated seeds cannot be "managed synchronously and differentially" - the former need to leave the liquid surface, while the latter still need to be immersed in liquid.

[0003] Therefore, a hydroponic germination incubator for agricultural seedling cultivation is disclosed in Chinese patent authorization publication number CN119790968B. The incubator can screen each individual cultivated seed through a purely mechanical structure, can distinguish each cultivated seed placed on the top of the support plate, lift the germinated cultivated seeds to the liquid level line, and change the environment in which the germinated cultivated seeds are located, while the cultivated seeds that have not yet germinated are still soaked in the culture solution, avoiding direct transfer of all of them, which will cause some of the cultivated seeds that have not yet germinated to be completely exposed to the air, thereby reducing the germination rate of the cultivated seeds.

[0004] However, the device has a complex structure and many parts. Each seed requires a set of "hemispherical hole + lifting rod + arc bracket + traction rope + counterweight block + pushing block + reset spring", which is equivalent to a miniature "manipulator". When the number of arrays increases, the number of parts will also increase exponentially, and the assembly, tolerance, and friction accumulation errors are extremely difficult to control. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of agricultural breeding equipment to solve at least one technical problem existing in the above-mentioned prior art.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 8 The present invention provides a technical solution: a new agricultural breeding equipment, comprising:

[0037] A chessboard breeder, the chessboard breeder has a plurality of through holes capable of accommodating seeds 13 and arranged in a row and column matrix, and each through hole corresponds to a unique coordinate;

[0038] A linear electromagnet is provided in each through hole, and the linear electromagnet has an iron core push rod 11 that can be vertically raised and lowered;

[0039] A light output unit is provided in each through hole, and the through hole serves as a light path of the light output unit;

[0040] A light receiving unit is provided above the through hole and corresponds to the through hole one by one, and the light receiving unit collects and receives the light signal passing through the seed 13;

[0041] And a control unit, which controls the linear electromagnet in the corresponding coordinate through hole to be energized according to the signal output by the light receiving unit, so that the iron core push rod 11 lifts the seed 13 and separates it from the liquid surface.

[0042] When the novel agricultural breeding device is used, first, individual seeds 13 are placed in the through holes of the chessboard breeder, and culture solution is poured into the holes to soak the seeds 13;

[0043] Secondly, during the soaking process of the seeds 13, the light output unit in the through hole emits a light signal and uses the through hole as a light path for illumination. The light receiving unit above the through hole needs to collect and receive the light signal passing through the seeds 13, thereby identifying whether the seeds 13 have germinated by judging its changes. The specific method is as follows:

[0044] First, after the seed 13 germinates, its physical thickness will decrease, that is, the originally thickest "waist" will be "hollowed out", so that the physical tissue through which the light path passes will be reduced, thereby increasing its light transmittance;

[0045] Secondly, the water absorption and expansion of the seeds 13 and the rupture of the cell walls will cause gaps and voids to appear inside the seeds, and the overall density will decrease, which will reduce the scattering of light and thus increase its light transmittance.

[0046] Therefore, after the seeds 13 germinate, the light receiving signal can monitor the change of the light path, thereby judging that the seeds 13 have germinated. At this time, the control unit will control the linear electromagnet in the corresponding through hole to energize according to the monitoring result of the light receiving unit and the signal it outputs, so that the iron core push rod 11 lifts the seeds 13 out of the through hole and out of the liquid surface, completing the differential treatment of the germinated seeds 13 and the ungerminated seeds 13;

[0047] Moreover, it is worth mentioning that due to the design of the iron core top rod 11 in the through hole, the light beam will present an aperture state when it is irradiated on the seed 13, and the iron core top rod 11 will leave an iron core shadow on the seed 13, and the iron core shadow is equivalent to a "centering hole", which can make the outer ring of the light spot always located at the change of the seed, because the position where the transmittance changes most clearly is the "waist" position of the seed, so the concentration of the aperture can increase the light intensity, thereby increasing the obviousness of the transmittance change and further reducing the possibility of error;

[0048] In this way, by upgrading the "mechanical single-seed picking" to "chessboard coordinates - contactless - electromagnetic array", each through-hole (that is, each seed) has a unique (x, y) coordinate, making the positioning precise enough and the processing upper limit higher.

[0049] In one of the more preferred embodiments, an implementation of a chessboard breeder is provided;

[0050] The chessboard breeder includes a chessboard base 1 and a chessboard base 3 that can be installed in combination with each other, and the through hole is composed of a seedling hole 2 opened through the chessboard base 1 and a bottom hole 7 opened in the chessboard base 3, and the seedling hole 2 and the bottom hole 7 are separated by a transparent spacer ring 8 embedded in the top of the chessboard base 3. A through hole is opened in the center of the transparent spacer ring 8, and the iron core top rod 11 is vertically sealed and slidably installed in the through hole.

[0051] Among them, the top surface of the chessboard base 1 is provided with a liquid tank, and the bottom of the liquid tank is provided with a stepped groove, the seedling hole 2 is provided in the stepped groove, and the culture liquid level in the liquid tank is flush with the height of the stepped groove.

[0052] For details, please refer to Figure 1-3During installation, first install the chessboard base 1 and the chessboard base 3 in a superimposed combination, and connect the seedling hole 2 and the bottom hole 7 to form a through hole, and tighten the two with bolts;

[0053] Secondly, the transparent spacer ring 8 and the iron core top rod 11 close the bottom of the seedling hole 2, thereby separating the seedling hole 2 from the bottom hole 7. In this way, most of the structure of the linear electromagnet (i.e., the coil skeleton 9, the copper wire winding 10) can be moved to the outside of the hole bottom, leaving only an "iron core top rod 11 that can slide up and down" in the seedling hole 2 and extending into the liquid, so that the copper wire winding 10, the coil skeleton 9 and the light source 6 are all in the dry area, making the structure easy to clean and replace.

[0054] Then, the design of the stepped groove can pour all the seeds 13 onto it, and then the seeds 13 can be made to enter the seedling holes 2 one by one by swinging the chessboard base 3 left and right and back and forth. There is no need to place the seeds 13 in the seedling holes 2 one by one, which can further improve work efficiency. Then the culture solution can be injected into the liquid tank until the liquid level is flush with the height of the stepped groove, and the height of the stepped groove is preferably 1 / 4 of the seed height, so that the seeds 13 can be partially separated from the culture solution after being pushed out of the seedling holes 2, so as to complete the differentiated treatment of the seeds 13.

[0055] It is worth mentioning that the design of the transparent spacer ring 8 can not only play the role of vertical sliding sealing for the iron core top rod 11, but also play the role of limiting it to keep it fixed after sliding, that is, after the copper wire winding 10 is energized and generates a magnetic field to push the iron core top rod 11 to move upward, the power can be cut off. The perforation in the center of the transparent spacer ring 8 will keep the iron core top rod 11 in a raised state, so that it can push the seeds 13 out of the top of the seedling hole 2. Specifically, a rubber ring can be designed in the perforation, which can not only ensure sliding sealing, but also provide limiting by squeezing the iron core top rod 11 through the rubber ring.

[0056] In one of the more preferred embodiments, an implementation of a light output unit is provided;

[0057] The light output unit is a light source 6 arranged below the bottom hole 7, and the light receiving unit includes a top plate 4 arranged above the chessboard base 1, and a plurality of light receivers 5 distributed in a row and column matrix and corresponding to the through holes one by one are installed at the bottom of the top plate 4.

[0058] The light source 6 is detachably mounted at the bottom opening of the bottom hole 7 by means of bolts.

[0059] For details, please refer to Figure 2-4 First, the light source 6 can be an LED patch, which can be detachably mounted on the bottom opening of the bottom hole 7 by bolt mounting or snap mounting, so that the entire through hole becomes its light path;

[0060] Subsequently, the light receiver 5 on the top plate 4 collects and receives the light in the corresponding through hole, and monitors the change in the light transmittance of the seed 13 by the intensity of the received light, thereby accurately locating the germinated seed 13 by coordinates.

[0061] In one of the more preferred embodiments, the linear electromagnet also includes a coil skeleton 9 installed in the bottom hole 7, the outer ring of the coil skeleton 9 is wound with a copper wire winding 10, and a portion of the iron core top rod 11 is located in the coil skeleton 9 and coincides with the axis position.

[0062] The control unit includes a plurality of column lines 15 and a plurality of row lines 14 passing through the chessboard base 3. The linear electromagnets are located at the intersections of the column lines 15 and the row lines 14 and are connected to the column lines 15 and the row lines 14 respectively.

[0063] The system also includes a control center, which controls only one column line 15 and one row line 14 to be electrically connected at the same time, so as to energize the linear electromagnet in the through hole of the only coordinate.

[0064] See Figure 3-4 as well as Figure 6 The linear electromagnet is located at the intersection of the column line 15 and the row line 14, and the positive and negative poles of the copper wire winding 10 are connected to the column line 15 and the row line 14 respectively. In this way, the chessboard-like power-on network composed of the column line 15 and the row line 14 can accurately position it. That is, when the control center controls only one column line 15 and one row line 14 to be electrically connected at the same time, only the linear electromagnet in one through-hole in the entire board is energized, thereby completing targeted processing and reducing the possibility of error.

[0065] For example, the control center (MCU) first scans the light transmission array (light receiving unit) and finds that the seed in the 3rd row and 5th column has germinated. Therefore, the MCU pulls up "row 3" to 5 V and pulls down the MOSFET corresponding to "column 5", so that only the copper wire winding 10 in row 3-column 5 is energized. Then the iron core push rod 11 moves up to push up the germinated seed 13, while the other copper wire windings 10 have no current. Then the MCU closes the row and column, and the iron core push rod 11 is limited by the transparent spacer ring 8 to maintain the ejection state. Finally, after all the seeds 13 have germinated and poured out, the iron core push rod 11 is pushed down and reset from the seedling hole 2 using a tool (preferably using a cover plate with multiple push rods corresponding to the through holes installed on the cover plate. By covering the cover plate on the chessboard base 1, the push rod is allowed to enter the seedling hole 2 and press the iron core push rod 11 back).

[0066] In a further preferred embodiment, the middle inner wall of the seedling raising hole 2 is provided with a chamfer, so that the seedling raising hole 2 forms a through hole that is wide at the top and narrow at the bottom, and the inner wall of the hole located in the upper section is further provided with shading cotton 12.

[0067] See Figure 3The setting of the chamfer inside the seedling hole 2 can form a chamfered conical aperture on its inner wall, which can fit the particle size of different seeds, eliminate the lateral gap and completely block the light, and the addition of the shading cotton 12 can also absorb stray light, prevent light leakage and multiple reflections caused by refraction of the liquid surface, and further improve the accuracy of the monitoring results;

[0068] Moreover, it is worth noting that the seedling raising hole 2 which is wide at the top and narrow at the bottom can play a role in straightening the seed 13, so as to further fix its posture so that it can sit in the seedling raising hole 2. In this way, through the role of limiting guidance, the radicle of the seed 13 can only grow downward, while the plumule is pushed upward. In this way, combined with the formation of the above-mentioned aperture, the radicle and plumule will be in the central shadow area and will not affect the edge of the light spot. In this way, the radicle extends downward and will "hollow out" the waist entity, allowing the light path to pass through less tissue, thereby making the transmittance detection more accurate.

[0069] In a further preferred embodiment, the diameter of the transparent spacer ring 8 is larger than the bottom opening diameter of the bottom hole 7, and a sealing ring 16 is embedded and installed at the bottom opening of the bottom hole 7. Figure 3-4 The design of the sealing ring 16 can further improve the sealing performance of the bottom of the seedling raising hole 2.

[0070] In one of the more preferred embodiments, the seedling raising hole 2 and the chessboard base 3 are connected by bolts, and the contact surfaces of the seedling raising hole 2 and the chessboard base 3 are respectively provided with corresponding grooves and convex surfaces, and the grooves and convex surfaces are both asymmetrically designed.

[0071] See Figure 7-8 The design of the groove and convex surface can facilitate the positioning and fitting of the seedling hole 2 and the chessboard base 3. At the same time, its asymmetric design can also distinguish the installation direction, facilitate installation, and prevent misalignment.

[0072] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0073] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
