Description

Technical Field

[0001] This utility model relates to the field of maize breeding technology, and in particular to a quick connection device for maize breeding. Background Technology

[0002] Maize breeding is a systematic process centered on the core goals of high yield, high quality, stress resistance, and wide adaptability. It involves the selection of parent lines, hybridization, offspring screening, and variety approval to improve the genetic traits of maize in a targeted manner and cultivate superior varieties that are suitable for different ecological zones and planting needs. It is a core technology to ensure maize production capacity and improve planting efficiency, and is suitable for diverse planting scenarios such as spring sowing, summer sowing, saline-alkali land, and dense planting.

[0003] In the existing technology, during the corn breeding process, the seeds need to be placed in the breeding tray in advance to ensure the breeding quality of the corn seeds. However, the size of the breeding tray is fixed, which is not convenient to adjust flexibly according to different usage needs, and it is difficult to quickly and flexibly disperse or splice multiple breeding trays. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a rapid connection device for maize breeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-connection device for maize breeding includes a breeding frame, a base plate, and multiple partitions. The base plate is fixedly connected to the inner wall of the breeding frame, and the multiple partitions are respectively fixedly connected to the upper surface of the base plate. An insert plate is fixedly connected to the right side of the breeding frame, and a slot is provided on the inner wall of the left side of the breeding frame. A cavity is provided on the inner wall of the breeding frame located in the slot. A metal elastic strip is fixedly connected to the inner wall of the cavity, and a limiting plug is fixedly connected to the top of the metal elastic strip. The limiting plug is slidably disposed on the inner wall of the cavity. A limiting hole is provided on the inner wall of the insert plate, and the limiting plug is inserted into the inner wall of the insert plate located in the limiting hole.

[0006] Preferably, the limiting block is configured as a trapezoidal block, and the insert plate is located on the inner wall of the limiting hole and matches the limiting block.

[0007] Preferably, the top side wall of the limiting insert has a rectangular groove, the inner wall of the rectangular groove is fixedly connected to a fixing rod, a clamping plate and a torsion spring are movably sleeved on the wall of the fixing rod, one end of the torsion spring is fixedly connected to the inner wall of the clamping plate, and the other end of the torsion spring is fixedly connected to the inner wall of the limiting insert. The breeding frame has a slot on the top inner wall of the cavity, and the clamping plate extends to the inner wall of the slot.

[0008] Preferably, an anti-slip rubber pad is fixedly connected to the end of the card plate away from the fixing rod, and the anti-slip rubber pad is pressed tightly against the inner wall of the card slot.

[0009] Preferably, a pull rope is fixedly connected to the side wall of the card plate, a sliding groove is provided on the inner wall of the limiting block, a slider is slidably provided on the inner wall of the sliding groove, and the pull rope extends into the interior of the sliding groove and is fixedly connected to the slider.

[0010] Preferably, a pull rod is fixedly connected to the bottom of the slider, and the end of the pull rod opposite to the slider extends to the outside of the breeding frame and is fixedly connected to a pull ring.

[0011] Compared with the prior art, this utility model provides a rapid connection device for maize breeding, which has the following beneficial effects: 1. This rapid connection device for corn breeding uses an insert plate to press and limit the insert block, pushing the limit insert block to slide downwards along the cavity, compressing the metal elastic strip on the inner wall of the cavity. When the limiting hole on the insert plate aligns with the limiting insert block, the metal elastic strip releases its elastic potential energy, pushing the limiting insert block to reset and insert into the limiting hole, thus achieving initial fixation of the two breeding frames. The matching of the limiting hole and the limiting insert block ensures connection stability.

[0012] 2. The quick connection device for corn breeding extends the locking plate in the rectangular groove at the top of the limiting plug into the slot at the top of the breeding frame cavity under the action of the torsion spring, further locking the limiting plug and preventing it from coming off the limiting hole due to external vibration, thus providing double protection for the connection.

[0013] 3. The quick connection device for corn breeding is fixed to the inner wall of the breeding frame by a base plate, and multiple partitions are evenly fixed to the upper surface of the base plate, dividing the inside of the breeding frame into multiple independent breeding areas. Multiple corn seedlings can be cultivated at the same time, improving breeding efficiency. The insert plate on the right side of the breeding frame cooperates with the slot on the left inner wall to realize the quick splicing of multiple breeding frames, meeting the space expansion needs of large-scale breeding.

[0014] 4. The quick connection device for corn breeding involves pulling the pull ring on the outside of the breeding frame. The pull ring causes the pull rod and slider to slide along the groove of the limiting insert. The slider pulls the card plate to compress the torsion spring through the pull rope, causing the card plate to disengage from the slot. Continuing to pull the pull ring causes the pull rod to drive the limiting insert to compress the metal elastic strip and exit the limiting hole. At this point, the insert can be pulled out of the slot, completing the disassembly of the breeding frame. The operation is convenient and efficient. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3 A quick connection device for maize breeding includes a breeding frame 1, a base plate 2, and multiple partitions 3. The base plate 2 is fixedly connected to the inner wall of the breeding frame 1, and the multiple partitions 3 are respectively fixedly connected to the upper surface of the base plate 2. An insert plate 4 is fixedly connected to the right side of the breeding frame 1, and a slot is provided on the inner wall of the left side of the breeding frame 1. A cavity is provided on the inner wall of the breeding frame 1 located in the slot. A metal elastic strip 5 is fixedly connected to the inner wall of the cavity. A limiting plug 6 is fixedly connected to the top of the metal elastic strip 5. The limiting plug 6 is slidably disposed on the inner wall of the cavity. A limiting hole is provided on the inner wall of the insert plate 4. The limiting plug 6 is inserted into the inner wall of the insert plate 4 located in the limiting hole. The limiting plug 6 is set as a trapezoidal block, and the inner wall of the insert plate 4 located in the limiting hole matches the limiting plug 6.

[0019] The top side wall of the limiting insert 6 has a rectangular groove, and the inner wall of the rectangular groove is fixedly connected to a fixing rod 7. A locking plate 8 and a torsion spring 9 are movably sleeved on the rod wall of the fixing rod 7. One end of the torsion spring 9 is fixedly connected to the inner wall of the locking plate 8, and the other end of the torsion spring 9 is fixedly connected to the inner wall of the limiting insert 6. The top inner wall of the breeding frame 1 located in the cavity has a slot, and the locking plate 8 extends to the inner wall of the slot.

[0020] The device uses a breeding frame 1, a base plate 2, and multiple partitions 3 as its core breeding structure. The base plate 2 is fixed to the inner wall of the breeding frame 1, and multiple partitions 3 are evenly fixed to the upper surface of the base plate 2, dividing the interior of the breeding frame 1 into multiple independent breeding areas. Multiple corn seedlings can be cultivated at the same time, improving breeding efficiency. The insert plate 4 on the right side of the breeding frame 1 cooperates with the slot on the left inner wall to realize the rapid splicing of multiple breeding frames 1, meeting the spatial expansion needs of large-scale breeding.

[0021] During assembly, the insert plate 4 of one breeding frame 1 is aligned with the slot of another breeding frame 1 and inserted. The insert plate 4 presses against the limiting insert 6, pushing the limiting insert 6 to slide downwards along the cavity, compressing the metal elastic strip 5 on the inner wall of the cavity. When the limiting hole on the insert plate 4 is aligned with the limiting insert 6, the metal elastic strip 5 releases its elastic potential energy, pushing the limiting insert 6 to reset and insert into the limiting hole, thus achieving the initial fixation of the two breeding frames 1. The limiting hole and the limiting insert 6 match to ensure connection stability.

[0022] Under the elastic force of the torsion spring 9, the locking plate 8 in the rectangular groove at the top of the limiting plug 6 extends into the locking groove at the top of the cavity of the breeding frame 1, further locking the limiting plug 6 and preventing it from coming off the limiting hole due to external vibration, thus providing double protection for the connection.

[0023] The entire device achieves rapid assembly and stable connection of the breeding frame through the precise docking of the insert plate 4 and the slot, the fixed limit insert 6 driven by the metal elastic strip 5, and the secondary locking structure of the card plate 8. At the same time, the disassembly process is simple and labor-saving, which can flexibly adapt to the planting needs of different scales in the corn breeding process, and improve the convenience and scale of breeding operations.

[0024] For ease of operation and high efficiency, such as Figure 1-3 As shown, an anti-slip rubber pad 10 is fixedly connected to one end of the card plate 8 away from the fixing rod 7. The anti-slip rubber pad 10 is pressed and set on the inner wall of the card slot. A pull rope 11 is fixedly connected to the side wall of the card plate 8. A sliding groove is opened on the inner wall of the limiting plug 6. A slider 12 is slidably provided on the inner wall of the sliding groove. The pull rope 11 extends into the interior of the sliding groove and is fixedly connected to the slider 12. A pull rod 13 is fixedly connected to the bottom of the slider 12. The end of the pull rod 13 away from the slider 12 extends to the outside of the breeding frame 1 and is fixedly connected to a pull ring 14.

[0025] The anti-slip rubber pad 10 at the end of the card plate 8 is pressed against the inner wall of the card slot to prevent slippage. When it is necessary to separate the breeding frame 1, pull the pull ring 14 on the outside of the breeding frame 1. The pull ring 14 drives the pull rod 13 and the slider 12 to slide along the slide groove of the limiting insert 6. The slider 12 pulls the card plate 17 to compress the torsion spring 9 through the pull rope 11, so that the card plate 17 is disengaged from the card slot. Continue to pull the pull ring 14, and the pull rod 13 drives the limiting insert 6 to compress the metal elastic strip 5 and exit the limiting hole. At this time, the insert plate 4 can be pulled out of the slot to complete the separation of the breeding frame 1. The operation is convenient and efficient.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
