Description
Technical Field
[0001] This utility model relates to the field of corn breeding equipment technology, and in particular to a novel corn breeding device. Background Technology
[0002] With the continuous improvement of agricultural production levels, maize breeding plays an increasingly important role in increasing crop yield, improving germplasm characteristics, enhancing resistance to diseases and pests, improving adaptability, and improving quality. As one of the world's most important food crops, the innovation and application of maize breeding technology are of profound significance for ensuring food security and promoting sustainable agricultural development. Modern maize breeding not only focuses on traditional yield increases but also emphasizes germplasm improvement and quality optimization to address challenges such as global climate change, environmental pollution, and resource scarcity. In the process of maize breeding and cultivation, the use of cultivation racks has become a key tool. It not only improves crop growth efficiency but also provides more precise environmental control for breeding, thereby maximizing breeding goals.
[0003] In existing technologies, corn breeding cultivation racks are usually designed with two layers of cultivation boxes. However, since corn needs sufficient sunlight for photosynthesis during its growth, the second cultivation box is often blocked by the upper layer, resulting in insufficient sunlight. This design limits the photosynthetic efficiency of corn, thus affecting the growth and breeding results of corn.
[0004] Therefore, we propose a new type of maize breeding device. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art and provide a new type of corn breeding device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel corn breeding device, comprising a base plate body and two cultivation box bodies. Vertical plates are fixedly installed on the top walls of the left and right sides of the base plate body. Two sliding grooves are respectively opened on the opposite end walls of the two vertical plates. Support plates are slidably arranged in the two upper sliding grooves and the two lower sliding grooves. Racks are fixedly installed on the left side walls of the two support plates that are close to each other. A driving mechanism for moving the two support plates is provided on the left vertical plate. The driving mechanism includes a transmission gear, a rotating rod, and a manual driving gear. A fixing box is fixedly installed on the left side wall of the left vertical plate. A limiting mechanism for limiting the manual driving gear is provided in the fixing box. The limiting mechanism includes a fixing plate, a locking block, a round rod, a pull plate, and a return spring.
[0007] As a preferred technical solution of this utility model, the right end of the rotating rod is fixedly connected to the left side wall of the transmission gear, and the left end of the rotating rod passes through the left vertical plate and is fixedly connected to the right side wall of the manual drive gear. The rotating rod is rotatably connected to the left vertical plate. By setting the rotating rod, the transmission gear can be rotated by the manual drive gear, which is convenient for operation.
[0008] As a preferred technical solution of this utility model, the position of the transmission gear corresponds to the position of the two racks, and the transmission gear meshes with the two racks respectively. By rotating the transmission gear, the two racks can drive the two support plates to be distributed alternately, and the corn seedlings in the cultivation box body on the two support plates can be fully exposed to sunlight.
[0009] As a preferred technical solution of this utility model, the outer wall of the fixing plate is slidably connected to the inner wall of the fixing box, the front wall of the fixing box is provided with a through opening, the rear end of the locking block is fixedly installed on the front wall of the fixing plate, the front end of the locking block extends through the through opening to the outside of the fixing box, and the locking block engages with the manual drive gear. By engaging the manual drive gear with the locking block, the transmission gear is prevented from rotating, thereby preventing the two bearing plates from moving.
[0010] As a preferred technical solution of this utility model, the front end of the round rod is fixedly installed on the rear end wall of the fixed plate, the rear end of the round rod passes through the fixed box and is fixedly connected to the front end wall of the pull plate, and the round rod is slidably connected to the fixed box. The position of the locking block can be adjusted by pulling the locking block through the round rod.
[0011] As a preferred embodiment of this utility model, the reset spring is sleeved on the outside of the round rod. The front end of the reset spring is fixedly connected to the rear end wall of the fixed plate, and the rear end of the reset spring is fixedly connected to the rear inner wall of the fixed box. The reset spring, through its elastic restoring force, enables the locking block to return to its initial position when not in operation. When an external force is applied, the spring will push the locking block back to the set position, ensuring that the locking block contacts the manual gear and limits the movement of the manual gear.
[0012] As a preferred technical solution of this utility model, a concave frame is fixedly installed on the rear top wall of the fixing box, and a rotating shaft is fixedly connected between the inner walls of the two sides of the concave frame. An L-shaped plate is rotatably connected to the outer wall of the rotating shaft. When the locking block is separated from the manual drive gear, the L-shaped plate rotates 90° to a horizontal state. The L-shaped plate can limit the pull plate and ensure the stable position of the pull plate.
[0013] As a preferred embodiment of this utility model, the top walls of the two support plates are fixedly installed with placement seats, and the two cultivation box bodies are respectively placed in the two placement seats.
[0014] This invention provides a novel corn breeding device. It has the following beneficial effects: 1. This novel corn breeding device, when used to provide photosynthesis for corn breeding, first pulls the pull plate, which moves the round rod and the fixed plate together and squeezes the return spring. At this time, the locking block moves accordingly, releasing the limit on the manual drive gear. Then, the manual drive gear is rotated, which drives the rotating rod and the transmission gear to rotate. In turn, the two racks drive the two support plates to move in opposite directions. In this way, the two placement seats and the two cultivation box bodies will move in an alternating manner, so that the corn breeding in the second layer of cultivation box bodies can fully contact sunlight, achieving uniform photosynthesis for all corn breeding, thereby improving the effect of corn breeding. This structure is simple in design, low in cost, and highly practical.
[0015] 2. In use, this new type of corn breeding device allows the L-shaped plate to rotate 90° to a horizontal position. The L-shaped plate then limits the position of the pull plate, ensuring its stability. This eliminates the need to pull the pull plate while manually rotating the drive gear, making the process more convenient. Attached Figure Description

Detailed Implementation
[0019] A new type of maize breeding device, such as Figure 1-4As shown, the system includes a base plate body 10 and two cultivation box bodies 11. Vertical plates 12 are fixedly installed on the top walls of the left and right sides of the base plate body 10. Two grooves 13 are respectively formed on the opposite end walls of the two vertical plates 12. Support plates 14 are slidably disposed within the two upper and two lower grooves 13. Racks 16 are fixedly installed on the left side walls of the two support plates 14 that are close to each other. A drive mechanism for moving the two support plates 14 is provided on the left vertical plate 12. The drive mechanism includes a transmission gear 17, a rotating rod 18, and a manual drive gear 19. A fixing box 20 is fixedly installed on the left side wall of the left vertical plate 12. A limiting mechanism for limiting the manual drive gear 19 is provided inside the fixing box 20. The positioning mechanism includes a fixed plate 21, a locking block 22, a round rod 23, a pull plate 24, and a return spring 25. The right end of the rotating rod 18 is fixedly connected to the left side wall of the transmission gear 17, and the left end of the rotating rod 18 passes through the left vertical plate 12 and is fixedly connected to the right side wall of the manual drive gear 19. The rotating rod 18 is rotatably connected to the left vertical plate 12. By setting the rotating rod 18, the transmission gear 17 can be rotated by the manual drive gear 19, which is convenient for operation. The position of the transmission gear 17 corresponds to the position of the two racks 16, and the transmission gear 17 is meshed with the two racks 16 respectively. By rotating the transmission gear 17, the two racks 16 can drive the two support plates 14 to be staggered, and the cultivation box bodies 11 on the two support plates 14 are aligned. The corn breeding system allows for ample sunlight exposure. The outer wall of the fixing plate 21 is slidably connected to the inner wall of the fixing box 20. A through-hole 26 is provided on the front wall of the fixing box 20. The rear end of the locking block 22 is fixedly installed on the front wall of the fixing plate 21. The front end of the locking block 22 extends through the through-hole 26 to the outside of the fixing box 20, and engages with the manual drive gear 19. This engagement prevents the transmission gear 17 from rotating, thus preventing the two support plates 14 from shifting. The front end of the round rod 23 is fixedly installed on the rear wall of the fixing plate 21. The rear end of the round rod 23 penetrates the fixing box 20 and is fixedly connected to the front wall of the pull plate 24. The round rod 23 is slidably connected to the fixing box 20, allowing the locking block 22 to be pulled. This adjusts the position of the card 22. A return spring 25 is sleeved on the outside of the round rod 23. The front end of the return spring 25 is fixedly connected to the rear end wall of the fixed plate 21, and the rear end is fixedly connected to the rear inner wall of the fixed box 20. The return spring 25, through its elastic restoring force, allows the card 22 to return to its initial position when not in operation. When an external force is applied, the return spring 25 will push the card 22 back to the set position, ensuring that the card 22 contacts the manual gear 19 and limits its movement. A concave frame 27 is fixedly installed on the rear top wall of the fixed box 20. A rotating shaft is fixedly connected between the inner walls of the two sides of the concave frame 27. An L-shaped plate 29 is rotatably connected to the outer wall of the rotating shaft. When the card 22 separates from the manual drive gear 19...The L-shaped plate 29 is rotated 90° to a horizontal position, which limits the position of the pull plate 24, ensuring its stability. Placement seats 15 are fixedly installed on the top walls of the two support plates 14, and the two cultivation box bodies 11 are placed in the two placement seats 15 respectively.
[0020] The working principle of this utility model is as follows: When photosynthesis is needed for corn breeding, the pull plate 24 is pulled first. The pull plate 24 moves the round rod 23 and the fixed plate 21 together and squeezes the return spring 25. At this time, the locking block 22 moves accordingly, releasing the limit on the manual drive gear 19. Then, the L-shaped plate 29 is rotated 90° to a horizontal position. The L-shaped plate 29 limits the pull plate 24 to ensure the stable position of the pull plate 24. Then, the manual drive gear 19 is rotated. The manual drive gear 19 drives the rotating rod 18 and the transmission gear 17 to rotate. Then, the two racks 16 drive the two bearing plates 14 to move in opposite directions. In this way, the two placement seats 15 and the two cultivation box bodies 11 will move in staggered steps, so that the corn breeding in the second layer of cultivation box bodies 11 can fully contact sunlight and achieve uniform photosynthesis for all corn breeding, thereby improving the effect of corn breeding. This structure is simple in design, low in cost and highly practical.
[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
