Description

Technical Field

[0001] This invention belongs to the field of agricultural equipment technology, specifically relating to a seed cleaning and packaging device for crop breeding machinery. Background Technology

[0002] Breeding engineering is a core component of sustainable agricultural development, and seed purity is a key indicator that determines the effectiveness of breeding and the quality of varieties.

[0003] Currently, breeding operations are generally conducted in multiple plots. Within a defined plot length, the same type of seed is simultaneously and evenly sown in each row, and any remaining seeds in the seed metering device are removed before moving to the next plot. Because the cultivation cost of experimental seedlings in breeding operations is high and their recovery value is significant, it is necessary to remove and recover any remaining seeds before moving to the next plot. Furthermore, the seeds should be accurately sorted and stored during the removal process to avoid waste and seed mixing.

[0004] However, in current mechanized breeding operations, seed mixing (such as the mixing of seeds from different varieties and generations) often occurs during sowing, harvesting, and cleaning due to defects in the mechanical structure design or improper operating procedures. This directly affects the genetic stability of breeding materials and can even cause significant economic losses. Therefore, breeders need to quickly clean and repackage the remaining seeds in the breeding machinery after sowing in each plot. However, in current technology, the removal, recycling, and repackaging of remaining seeds are still done manually. This undoubtedly increases the workload and has problems such as low efficiency, many dead spots for residue, and poor adaptability. Moreover, with the promotion of large-scale and intensive breeding models, manual processing cannot meet the requirements of simultaneous sowing in the same plot on the same day.

[0005] In summary, it is also necessary to design a highly automated device that can effectively remove and classify the remaining seeds after sowing in the plot, thereby improving breeding efficiency and reducing the error rate. Summary of the Invention

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] In the description of this invention, it should be understood that the relative relationships indicated by terms such as "upper," "lower," "top," and "side" are based on the order of contact with the material in the rotation direction in actual application, and are used for the convenience of describing this invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, and therefore should not be construed as a limitation of this invention.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] It should also be noted that, unless otherwise specified, the methods used in this invention are conventional methods; and the raw materials and apparatus used are, unless otherwise specified, conventional commercially available products.

[0051] This application provides a method such as Figure 1 , Figure 2 The crop breeding machinery seed cleaning and dispensing device shown mainly includes a first channel 1, a second channel 3, a multi-way reversing valve 2, a seed storage chamber 4, and a negative pressure air chamber 5.

[0052] In this embodiment, a single-inlet strategy is adopted, with only one first channel 1 for illustrative purposes. It can be understood that in scenarios where multiple crop breeding machines require seed cleaning and the seeds are of the same type, multiple first channels can be set up and connected to a single inlet. Preferably, in this embodiment, to meet the needs of complex connection scenarios, the main body of the first channel 1 is designed as a flexible hose structure. The upper end connects to the seed cleaning port of the crop breeding machine via a rotating interface, and the lower end connects to the inlet of the multi-way reversing valve 2. Furthermore, the rotating interface uses a sealed structure to maintain sufficient suction, and the tube body of the first channel can rotate around its axis, thereby increasing the degree of freedom in connection. The rotating interface can be connected to the crop breeding machine via a flange or a quick-release structure, the details of which will not be elaborated further.

[0053] There are multiple second channels 3; in this embodiment, 20 channels are used as an example. Each second channel 3 connects to one outlet of the multi-way reversing valve 2 and a corresponding seed storage chamber 4. Therefore, to reduce the size of the device, a honeycomb layout is adopted, i.e., the 20 second channels 3 are stacked in layers, with a fixed partition added in the middle. The fixed partition has honeycomb-like through holes as auxiliary mounting positions for the second channels 3. Each second channel 3 passes through the corresponding through hole and is fixed thereto, connecting to a corresponding seed storage chamber 4 at its end. In this embodiment, for overall structural stability, the second channels 3 are designed using rigid materials, such as stainless steel bends, thus forming a robust main structure through the multi-way reversing valve 2, second channels 3, fixed partition, seed storage chamber 4, and negative pressure chamber 5.

[0054] like Figure 3As shown, the seed storage chamber 4 has a seed inlet and an air outlet. In this embodiment, the second channel 3 is connected to the seed storage chamber 4 via a plug-in structure, and the connection between the seed storage chamber 4 and the negative pressure chamber 5 is also via a plug-in structure. The seed inlet and air outlet of the seed storage chamber 4 are used as plug-in interfaces 401, and sealing rings are installed on the inner side to ensure an interference fit with the plugs on the second channel 3 and the negative pressure chamber 5. This helps maintain negative pressure and increases connection stability. When it is necessary to remove the seed storage chamber 4 for seed extraction, simply fix the negative pressure chamber 5, then pull out the fixed partition to separate the second channel 3 and the seed storage chamber 4. Seeds can then be extracted from each seed storage chamber 4 sequentially from the negative pressure chamber 5 as needed. A detachable screen 402 is installed at the air outlet of the seed storage chamber 4. Figure 4 As shown, the screen 402 has a cap-like structure, is fastened to the air outlet, and has a convex arc shape on its surface. The mesh size is designed to ensure that the aperture of the surface sieve holes is smaller than the minimum particle size of the remaining seeds to be recovered. In another embodiment, to prevent seeds from adsorbing onto the screen 402 under suction and to reduce the clogging effect of impurities on the screen, such as... Figure 5 As shown, an anti-clogging cone cap 403 is installed above each filter screen 402. It is a cone structure with a shell-pulling mechanism. The bottom is fixed to the inner bottom surface of the seed storage chamber 4 by a connecting rod, and there is an operating space between it and the filter screen 402 to facilitate the removal and placement of the filter screen 402.

[0055] The negative pressure chamber 5 is a disc-shaped hollow structure with 21 protruding air inlets on the top surface for inserting 20 seed storage chambers 4. One air inlet is reserved for installing a manual valve for temporary pressure relief during disassembly and assembly. The negative pressure chamber 5 is also connected to a negative pressure fan through an air outlet to provide the negative pressure required by the device.

[0056] Furthermore, such as Figure 6 and Figure 7 As shown, the multi-way directional valve 2 in this embodiment includes a valve core 201 and a valve body 203. The valve body 203 is fixedly connected to the second channel 3 on the periphery.

[0057] The valve core 201 has a cylindrical structure and an internal valve core passage connecting the top and side surfaces. In the valve core passage, the port on the top surface of the valve core is the inlet of a multi-way directional valve, connected to the first channel 1; the port on the side surface of the valve core is the first switching port 2011. The valve core passage is used to guide the contents of the first channel 1 that have fallen into the first channel 1 to the first switching port 2011 on the side.

[0058] The valve body 203 has a cylindrical structure with 20 second switching ports 2031 arranged on the side, which are fixedly connected to the corresponding second channels 3.

[0059] The valve core 201 is nested within the valve body 203 and rotatably connected to it. To ensure sealing, the valve core 201 and valve body 203 are fitted with a clearance fit. A valve core connecting rod 202 is coaxially fixed to the lower part of the valve core 201 for connecting to a drive mechanism. The drive mechanism is used to drive the first switching port 2011 to align and communicate with the corresponding second switching port 2031.

[0060] To reduce hardware size, the second switching port 2031 in this embodiment is designed in a stacked form, that is, multiple second switching ports 2031 are distributed in multiple rings on the side of the valve body 203, specifically in two rings, one above the other, with 10 second switching ports 2031 evenly distributed in each ring.

[0061] Therefore, the drive mechanism is selected as an electrically controlled rotary lifting mechanism, specifically an electrically controlled lifting turntable. The table surface is coaxially fixed with the valve core connecting rod 202, thereby achieving the alignment and connection of the second switching port 2031 and the first switching port 2011 as needed through lifting and rotation control.

[0062] Furthermore, considering that the storage location of the remaining seeds needs to be adjusted according to the actual situation during the recycling process, marking the seed storage chamber 4 would waste a lot of time. Therefore, electronic tag technology is used to achieve electronic control processing. Thus, in this embodiment, a tag reader / writer is provided on the valve core 201, and a digital tag is provided at each of the second switching ports 2031 on the valve body 203. Specifically, NFC technology is used. An NFC reader / writer is installed above the first switching port 2011, and an NFC tag is installed at the corresponding position above each second switching port. In this way, when a recycling operation is performed, the NFC reader / writer writes or reads seed information on the aligned NFC tags. Therefore, during unified recycling, the seed information can be quickly determined by reading the NFC tag information, instead of relying on the control system to record alignment records and determine seed information. This avoids seed information errors caused by merged recycling or system problems.

[0063] Preferably, this embodiment also includes an angle sensor on the valve core 201 for calibrating the drive mechanism, preventing error accumulation that could lead to alignment deviations between the first and second switching ports. Furthermore, considering that not all seeds are perfectly rounded, even a slight misalignment between the first switching port 2011 and the second switching port 2031 could cause the seed to jam and fail to fall and be retrieved. Therefore... Figure 8As shown, this embodiment also designs the inner diameter D of the first switching port to be larger than the inner diameter d of the second switching port, and processes a sharp rounded corner 2012 (the edge is concave and rounded inward) at the edge of the first switching port 2011, and the inner diameter of the rounded corner end is equal to the inner diameter d of the second switching port. The advantage of this design is that even if the first and second switching ports have a slight misalignment due to the accumulation of errors over a period of time, the sharp rounded corner can form a guiding structure to guide the seed into the second switching port 2031, thereby avoiding the seed getting stuck at the misalignment.

[0064] In another embodiment, in order to reduce the number of power units in the drive mechanism and reduce costs, the design is as follows: Figure 9 and Figure 10 As shown, the aforementioned multiple second switching ports 2031 are spirally distributed on the side of the valve body 203. A nut is fixedly installed by opening a hole in the center of the negative pressure chamber 5, and an external thread 2021 (or a spiral slide for use with ball bearings) is machined on the valve core connecting rod 202, so that the valve core 201 and the entire device are spirally engaged. Furthermore, a rotating mechanism is installed at the lower part of the device, which is driven by a motor 7 to rotate a turntable 6. The center hole of the turntable 6 is axially slidably connected to the valve core connecting rod 202, and a key connection is used to achieve circumferential linkage between the valve core connecting rod 202 and the turntable 6. The advantage of this design is that the lifting / lowering and rotational movement of the valve core 201 can be achieved by rotating a single motor, and since the second switching ports 2031 are spirally distributed, the controlled alignment of the first switching port 2011 and the required second switching ports 2031 can also be achieved similarly.

[0065] It is also necessary to consider that, in the above embodiment, although the first channel 1 is a flexible tube structure, since the valve core 201 has a lifting and lowering motion, the length of the movable end of the first channel 1 should be greater than the maximum lifting and lowering height of the valve core 201, and should not be too long, so as to avoid the situation of seeds being stored at the bend.

[0066] Work process:

[0067] When residual seed cleaning and recycling operations are required, the negative pressure fan is activated, and the drive mechanism is controlled according to preset conditions to drive the valve core to rise / fall and rotate, thereby aligning the first switching port with the designated second switching port. This forms a passage between the negative pressure chamber and the seed cleaning port of the crop breeding machinery. Under the action of negative pressure, the airflow flows from the seed cleaning port of the crop breeding machinery to the designated seed storage chamber. The residual seeds in this operation... Figure 2 The seeds fall into the storage chamber along the path indicated by the middle arrow; when the recycling work is completed, the drive mechanism drives the valve core back to the zero position or deflects it at an angle so that the first switching port is no longer aligned with any of the second switching ports.

[0068] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
