Description

Technical Field

[0001] This utility model relates to the field of agricultural mechanization technology, and in particular to a seed uniformr for seedling trays. Background Technology

[0002] Agricultural mechanization refers to the process of using advanced and applicable agricultural machinery and technology to replace traditional manual and animal labor, improve agricultural production conditions, and enhance agricultural productivity, efficiency, and the quality of agricultural products.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the scraper device of the seedling tray sowing uniform device has a fixed height and cannot be compatible with seedling trays of different specifications. This results in the equipment being able to adapt to seedling trays of a single height. The gap between the scraper and the tray surface is too large, requiring manual secondary leveling. Seedling trays that are too high cause the scraper to collide with the edge of the tray, resulting in tray jamming, substrate splashing, and equipment shutdown. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the scraper device of the seedling tray sowing uniform device has a fixed height and cannot be compatible with seedling trays of different specifications. Therefore, we propose a seedling tray sowing uniform device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a seedling tray sowing uniform device, including a conveying device, a first soil covering machine installed on the top of the conveying device, a sower installed on the top of the conveying device, a second soil covering machine installed on the top of the conveying device, two fixed blocks fixedly connected to one end of the second soil covering machine, an adjustment groove opened at one end of the fixed block, an adjustment block slidably connected inside the adjustment groove, a fixed plate fixedly connected to one end of the adjustment block, a flat plate installed at the bottom of the fixed plate, a square groove opened at one end of the adjustment block, a column fixedly connected inside the square groove, an irregularly shaped locking block slidably connected to the surface of the column, the surface of the irregularly shaped locking block slidably connected to the inside of the square groove, a plurality of limiting grooves opened on one side of the adjustment groove, and one side of the irregularly shaped locking block slidably connected to the inside of the limiting groove.

[0006] Preferably, sliding grooves are provided on both sides of the adjustment groove, and sliding blocks that cooperate with the sliding grooves are fixedly connected to both sides of the adjustment block, and the surface of the sliding block is slidably connected to the inside of the sliding groove.

[0007] Preferably, a first spring is slidably connected to the surface of the column rod, one end of the first spring is fixedly connected to the irregularly shaped locking block, and the other end of the first spring is fixedly connected to one side of the square groove.

[0008] Preferably, the top and bottom of the square groove are provided with guide grooves, and the top and bottom of one side of the irregularly shaped card block are fixedly connected with guide blocks that cooperate with the guide grooves. The surface of the guide block is slidably connected to the inside of the guide groove.

[0009] Preferably, the bottom of the fixing plate is provided with an installation groove, the interior of the installation groove is engaged with the surface of the plate, both sides of the plate are provided with circular grooves, the interior of the circular grooves is fixedly connected with a second spring, the other end of the second spring is fixedly connected with a limit post, the bottom of the fixing plate is fixedly connected with a snap-fit ​​plate, and the surface of the limit post is slidably connected with the interior of the snap-fit ​​plate.

[0010] Preferably, a limiting plate is fixedly connected to the surface of the limiting post, and the surface of the limiting plate is slidably connected to the inside of the circular groove.

[0011] Preferably, a first magnetic block is fixedly connected to the top of the mounting groove, and a second magnetic block is fixedly connected to the top of the flat plate, with the first magnetic block and the second magnetic block being magnetically connected.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pulling the irregularly shaped locking block, one side of the block moves out of the limiting groove. At this time, the limiting of the adjusting block inside the adjusting groove is released. The adjusting block can then be adjusted according to the height of the seedling tray, causing the adjusting block to drive the fixing plate, which in turn drives the entire plate to move. After adjustment, the movement of the irregularly shaped locking block is released, allowing one side of the block to return to the limiting groove, thus re-limiting the adjusting block. The seedling tray is conveyed on the surface of the conveying device. When passing the bottom of the entire plate, the plate levels the top soil covering the tray, ensuring even distribution. This design allows for the adaptation of seedling trays of different heights, enhancing the equipment's versatility and reducing the problem of leveling failure due to mismatched tray specifications, as well as operational difficulties and maintenance costs caused by size differences.

[0013] In this invention, by pressing the limiting post, the limiting post is moved out of the inside of the snap-fit ​​plate. At this time, the limiting position of the plate is released inside the mounting groove, and the plate can be removed from the bottom of the fixing plate. When it is necessary to reinstall the plate into the inside of the fixing plate, press the limiting post to press the limiting post into the inside of the circular groove, and then reset the plate into the inside of the mounting groove. Release the pressing of the limiting post, and the elasticity of the second spring will automatically abut the limiting post and enter the inside of the snap-fit ​​plate. This setting can support the quick disassembly and assembly of the plate to adapt to special plate for different crops or substrate types. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figures 1-4As shown, this utility model provides a technical solution: a seedling tray sowing uniform device, including a conveying device 1, a first covering machine 2 installed on the top of the conveying device 1, a seeder 3 installed on the top of the conveying device 1, a second covering machine 4 installed on the top of the conveying device 1, two fixing blocks 5 fixedly connected to one end of the second covering machine 4, an adjusting groove 6 opened at one end of the fixing block 5, an adjusting block 7 slidably connected inside the adjusting groove 6, a fixing plate 8 fixedly connected to one end of the adjusting block 7, a leveling plate 9 installed at the bottom of the fixing plate 8, a square groove 10 opened at one end of the adjusting block 7, a column rod 11 fixedly connected inside the square groove 10, an irregularly shaped locking block 12 slidably connected to the surface of the column rod 11, the surface of the irregularly shaped locking block 12 slidably connected to the inside of the square groove 10, a plurality of limiting grooves 13 opened on one side of the adjusting groove 6, and one side of the irregularly shaped locking block 12 slidably connected to the inside of the limiting groove 13. The sliding connection allows the irregularly shaped locking block 12 to be pulled, causing one side of the block to move out of the limiting groove 13. At this point, the limiting position of the adjusting block 7 inside the adjusting groove 6 is released. The adjusting block 7 can then be adjusted according to the height of the seedling tray, causing it to move the fixing plate 8. The fixing plate 8 then moves the entire plate 9. After adjustment, the movement of the irregularly shaped locking block 12 is released, allowing one side of the block to return to the limiting groove 13, thus re-limiting the adjusting block 7. The seedling tray is conveyed on the surface of the conveying device 1. When passing the bottom of the entire plate 9, the entire plate 9 levels the top soil covering the tray, ensuring even distribution of the soil. This design allows for the adaptation of seedling trays of different heights, enhancing the equipment's versatility and reducing the leveling failure caused by mismatched tray specifications, as well as operational difficulties and maintenance costs due to size differences.

[0018] Reference Figure 2 and Figure 3 As shown in this embodiment: sliding grooves 14 are provided on both sides of the adjusting groove 6, and sliding blocks 15 that cooperate with the sliding grooves 14 are fixedly connected to both sides of the adjusting block 7. The surface of the sliding block 15 is slidably connected to the inside of the sliding groove 14. By allowing the sliding block 15 to slide inside the sliding groove 14, the movement position of the adjusting block 7 can be restricted, making the movement of the adjusting block 7 more stable.

[0019] Reference Figure 2 As shown in this embodiment: a first spring 16 is slidably connected to the surface of the column rod 11. One end of the first spring 16 is fixedly connected to the irregularly shaped block 12, and the other end of the first spring 16 is fixedly connected to one side of the square groove 10. By setting the first spring 16, the elasticity of the first spring 16 abuts against the irregularly shaped block 12, which can restrict the movement of the irregularly shaped block 12 and prevent the irregularly shaped block 12 from being displaced due to the vibration generated by the operation of the equipment.

[0020] Reference Figure 2As shown in this embodiment: guide grooves 17 are provided at the top and bottom of the square groove 10. Guide blocks 18 are fixedly connected to the top and bottom of one side of the irregularly shaped card block 12 to cooperate with the guide grooves 17. The surface of the guide block 18 is slidably connected to the inside of the guide groove 17. By allowing the guide block 18 to slide inside the guide groove 17, the movement of the irregularly shaped card block 12 can be guided, avoiding unnecessary deviation of the irregularly shaped card block 12 during movement, and allowing the irregularly shaped card block 12 to accurately enter the inside of the limiting groove 13.

[0021] Reference Figure 5 As shown in this embodiment: The bottom of the fixing plate 8 has a mounting groove 19, the interior of which engages with the surface of the flat plate 9. Both sides of the flat plate 9 have circular grooves 20, the interior of which is fixedly connected to a second spring 21. The other end of the second spring 21 is fixedly connected to a limiting post 22. The bottom of the fixing plate 8 is fixedly connected to a snap-fit ​​plate 23, the surface of which is slidably connected to the interior of the snap-fit ​​plate 23. By pressing the limiting post 22, it is moved out of the snap-fit ​​plate 23, at which point the flat plate 9... With the limit released inside the mounting slot 19, the flat plate 9 can be removed from the bottom of the fixing plate 8. When it is necessary to reinstall the flat plate 9 into the fixing plate 8, press the limit post 22 to press the limit post 22 into the circular groove 20, and then reset the flat plate 9 into the mounting slot 19. Release the press on the limit post 22, and the elasticity of the second spring 21 will automatically abut against the limit post 22 and enter the interior of the snap-fit ​​plate 23. This setting can support the quick disassembly and assembly of the flat plate 9 to adapt to special flat plates 9 for different crops or substrate types.

[0022] Reference Figure 5 As shown in this embodiment: the surface of the limiting post 22 is fixedly connected to the limiting plate 24, and the surface of the limiting plate 24 is slidably connected to the inside of the circular groove 20. By setting the limiting plate 24, the movement position of the limiting post 22 can be restricted, and the limiting post 22 is prevented from coming out of the inside of the circular groove 20 due to the excessive elasticity of the second spring 21.

[0023] Reference Figure 5 As shown in this embodiment: a first magnetic block 25 is fixedly connected to the top of the mounting groove 19, and a second magnetic block 26 is fixedly connected to the top of the plate 9. The first magnetic block 25 and the second magnetic block 26 are magnetically connected. By setting the second magnetic block 26 and the first magnetic block 25, the plate 9 is guided when it is installed inside the mounting groove 19, making the installation process of the plate 9 more stable.

[0024] Working principle: By pulling the irregularly shaped locking block 12, one side of the irregularly shaped locking block 12 moves out of the limiting groove 13. At this time, the limiting of the adjusting block 7 inside the adjusting groove 6 is released. At this time, the adjusting block 7 can be adjusted according to the height of the seedling tray, so that the adjusting block 7 drives the fixing plate 8, and the fixing plate 8 drives the whole plate 9 to move. After the adjustment is completed, the movement of the irregularly shaped locking block 12 is released, so that one side of the irregularly shaped locking block 12 returns to the limiting groove 13, and the adjusting block 7 is limited again. The seedling tray is conveyed on the surface of the conveying device 1. When it passes the bottom of the whole plate 9, the whole plate 9 removes the soil covering the top of the tray. Leveling ensures the soil is evenly distributed on the top of the seedling tray. This design adapts to seedling trays of different heights, enhancing equipment versatility and reducing leveling failures caused by mismatched tray sizes, as well as operational inconveniences and maintenance costs due to size differences. By allowing the sliding block 15 to slide within the sliding groove 14, the movement of the adjusting block 7 is restricted, making its movement more stable. The first spring 16, with its elasticity, abuts against the irregularly shaped locking block 12, limiting its movement and preventing displacement due to vibrations from equipment operation. By allowing the guide block 18 to slide inside the guide groove 17, the movement of the irregularly shaped locking block 12 can be guided, preventing unnecessary deviation of the irregularly shaped locking block 12 during movement, and ensuring that the irregularly shaped locking block 12 accurately enters the interior of the limiting groove 13. By pressing the limiting post 22, the limiting post 22 is moved out of the interior of the locking plate 23. At this time, the limiting of the plate 9 inside the mounting groove 19 is released, and the plate 9 can be removed from the bottom of the fixing plate 8. When it is necessary to reinstall the plate 9 into the interior of the fixing plate 8, press the limiting post 22 to press the limiting post 22 into the interior of the circular groove 20, and then reset the plate 9 to its original position. Inside the mounting slot 19, when the pressing of the limiting post 22 is released, the elasticity of the second spring 21 automatically abuts against the limiting post 22 and enters the interior of the snap-fit ​​plate 23. This setting allows for the quick assembly and disassembly of the plate 9 to adapt to special plate 9s for different crops or substrate types. The limiting plate 24 restricts the movement of the limiting post 22, preventing the limiting post 22 from coming out of the circular slot 20 due to excessive elasticity of the second spring 21. The second magnetic block 26 and the first magnetic block 25 provide guidance when the plate 9 is installed inside the mounting slot 19, making the installation process of the plate 9 more stable.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
