Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a seedling planting hole punching device. Background Technology

[0002] Seedling tray cultivation, as a key upstream link in modern agricultural production, has significant advantages such as saving seeds, high survival rate, good seedling quality, and ease of standardized management and mechanized transplanting. It has become a core technology for the production of cash crops such as vegetables, flowers, and tobacco. In the seedling tray cultivation process, "perforation" is a crucial step after the seedling tray is filled with substrate and before sowing. Its purpose is to create a germination environment with suitable depth and density for the seeds. Traditional manual perforation relies entirely on the operator's experience and physical strength, making it difficult to ensure that hundreds of holes are at a consistent depth. Sowing too deep can lead to seed hypoxia and delayed germination; sowing too shallow may cause seeds to emerge with their seed coats still attached, affecting seedling growth. Therefore, a seedling planting perforation device needs to be designed.

[0003] To this end, patent CN205812725U discloses a seedling planting hole-punching device, relating to the field of agricultural planting technology. It includes a base, vertical guide columns on both sides of the base, a fixed crossbeam fixed to the upper end of the guide columns, a movable crossbeam slidably mounted on the guide columns, a hole-punching mechanism connected to the lower part of the movable crossbeam, and a vertical transmission mechanism fixed to the fixed crossbeam. The lower end of the vertical transmission mechanism is connected to the upper part of the movable crossbeam. The hole-punching mechanism is equipped with a nutrient solution distribution mechanism. Both the vertical transmission mechanism and the nutrient solution distribution mechanism are connected to a microcomputer controller. During hole punching, the vertical transmission mechanism drives the movable crossbeam downwards. Guided by the guide columns, the hole-punching mechanism at the lower part of the movable crossbeam moves towards the base, punching holes in the seedling pots placed on the base and filled with potting soil. Simultaneously, the nutrient solution distribution mechanism adds nutrient solution to the potting soil in the seedling pots. This utility model's seedling planting hole-punching device can achieve rapid hole punching while simultaneously adding nutrient solution.

[0004] Although the seedling planting hole punching device mentioned above allows for the addition of nutrient solution during hole punching, it is inconvenient to adjust the hole spacing according to the planting needs of the seedlings during daily use, which can easily affect the subsequent growth of the seedlings. Therefore, it is necessary to design a seedling planting hole punching device. Utility Model Content

[0005] The purpose of this invention is to provide a seedling planting hole-drilling device to solve the problem that existing seedling planting hole-drilling devices are inconvenient to adjust the hole spacing according to the planting needs of seedlings during daily use, which can easily affect the subsequent growth of seedlings.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seedling planting hole punching device, including a connecting frame;

[0007] Both ends of the connecting frame are fixed with a disassembly structure;

[0008] The bottom end of the connecting frame is provided with an adjustable punching structure. The adjustable punching structure includes a positioning plate disposed below the connecting frame. Mounting plates are fixed on both sides of the bottom end of the positioning plate. Connecting blocks are evenly disposed between the mounting plates. Punching blocks are fixed at the bottom end of each connecting block.

[0009] Each connecting block has a limit rod running through its interior, and a locking shaft is threaded to one side of the top of each connecting block. One end of each locking shaft extends to the outside of the connecting block and is fixedly connected to a rotating handle.

[0010] Preferably, a telescopic structure is fixed to the top of the connecting frame, a handle is fixed to the top of the telescopic structure, and a suspension block is fixed to one side of the top of the handle.

[0011] Preferably, the disassembly and assembly structure includes a limiting frame, a fixing bolt, and an installation bolt. The limiting frames are all located on both sides of the top of the connecting frame. A fixing bolt is evenly inserted through one side of the inside of the limiting frame, and an installation bolt is evenly inserted through the other side of the inside of the limiting frame.

[0012] Preferably, the bottom ends of the fixing bolts all extend into the interior of the connecting frame, and the bottom ends of the mounting bolts all pass through the positioning plate and extend to the exterior of the limiting frame.

[0013] Preferably, the connecting blocks are evenly distributed below the positioning plate, and the main view cross-section of the perforated block is trapezoidal.

[0014] Preferably, the connecting block and the limiting rod are slidably connected, and one end of the locking shaft abuts against one side of the limiting rod.

[0015] Preferably, the telescopic structure includes a telescopic seat fixed at the middle position of the top of the connecting frame, a telescopic shaft is provided on the top of the telescopic seat, locking pieces are uniformly fixed on the top of the telescopic seat, a limit ring is fixed on the outer wall of the top of the telescopic seat, and a locking sleeve is sleeved on the outer side of the telescopic seat above the limit ring.

[0016] Preferably, the central axes of the telescopic seat and the telescopic shaft are collinear, and the locking pieces are evenly distributed at the top of the telescopic seat.

[0017] Preferably, the locking sleeve and the locking plate are threaded together.

[0018] The advantages of the seedling planting hole-punching device provided by this utility model are as follows:

[0019] By incorporating an adjustable perforation structure and moving the connecting block on the limiting rod, the spacing between multiple perforation blocks can be adjusted to adapt to different tray sizes or crop planting needs. The locking shaft and rotating handle work together to quickly lock or loosen the connecting block, ensuring stability after the perforation spacing is adjusted and preventing displacement during operation. The perforation block is designed with a trapezoidal cross-section, which is conducive to forming a hole shape that is larger at the top and smaller at the bottom, facilitating seed placement and substrate backfilling, improving sowing quality and germination rate. This device enables easy adjustment of the perforation spacing, enhancing the convenience and applicability of the seedling planting perforation device in use.

[0020] With a detachable structure, reliable connections between the limiting frame and the connecting frame, and between the limiting frame and the positioning plate, can be achieved through fixing bolts and mounting bolts, ensuring the overall structure is stable during drilling operations. The detachable design facilitates cleaning, replacement, or maintenance of the drilling components, extending the device's service life. It also allows users to replace drilling modules with different spacing or sizes according to different specifications of seedling trays or planting needs, improving the device's versatility. This gives the device the function of easy overall disassembly and adjustable drilling structure, improving the convenience and applicability of the seedling planting drilling device during use.

[0021] By incorporating a telescopic structure, the overall height of the drilling device can be adjusted by changing the extension length of the telescopic shaft, making it convenient for users of different heights. The use of a threaded locking mechanism between the locking plate and the locking sleeve ensures easy adjustment and reliable locking, preventing the telescopic shaft from slipping during operation. This allows the device to be easily adjusted in overall height, improving the convenience and applicability of the seedling planting drilling device. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 The present invention provides a seedling planting hole punching device, including a connecting frame 1.

[0030] Reference Figures 1-5 As shown, both ends of the connecting frame 1 are fixed with a disassembly structure 2. The disassembly structure 2 includes a limiting frame 21, a fixing bolt 22, and a mounting bolt 23. The limiting frames 21 are all located on both sides of the top of the connecting frame 1. The fixing bolt 22 is evenly penetrated through one side of the inside of the limiting frame 21, and the mounting bolt 23 is evenly penetrated through the other side of the inside of the limiting frame 21. The bottom end of the fixing bolt 22 extends into the inside of the connecting frame 1, and the bottom end of the mounting bolt 23 passes through the positioning plate 31 and extends to the outside of the limiting frame 21.

[0031] During installation, place the limiting frame 21 on both sides of the connecting frame 1. By screwing in the fixing bolt 22, the bottom end of the limiting frame 21 can be inserted into the interior of the connecting frame 1, thus fixing the limiting frame 21 to both ends of the connecting frame 1. Then, the adjustable drilling structure 3 can be fixed by the limiting frame 21 and the mounting bolt 23. Insert the positioning plate 31 into the position between the limiting frame 21 and the connecting frame 1. Then, pass the mounting bolt 23 through the limiting frame 21 and the positioning plate 31 to achieve lateral locking. When disassembling, unscrew the mounting bolt 23 in the opposite direction to remove the positioning plate 31 from the inside of the limiting frame 21, which facilitates the replacement and maintenance of the adjustable drilling structure 3.

[0032] Reference Figures 1-5As shown, the bottom end of the connecting frame 1 is provided with an adjustable perforation structure 3. The adjustable perforation structure 3 includes a positioning plate 31 located below the connecting frame 1. Mounting plates 35 are fixed on both sides of the bottom end of the positioning plate 31. Connecting blocks 32 are evenly arranged between the mounting plates 35. A perforated block 33 is fixed to the bottom end of each connecting block 32. A limit rod 34 passes through the interior of each connecting block 32. A locking shaft 36 is threaded to one side of the top of each connecting block 32. One end of the locking shaft 36 extends to the outside of the connecting block 32 and is fixedly connected to a rotating handle 37. The connecting blocks 32 are evenly distributed below the positioning plate 31. The main view section of the perforated block 33 is trapezoidal. The connecting blocks 32 and the limit rod 34 are slidably connected. One end of the locking shaft 36 abuts against one side of the limit rod 34.

[0033] When the spacing needs to be adjusted, rotate the handle 37. The handle 37 will drive the locking shaft 36 to rotate, so that one end of the locking shaft 36 moves away from the limiting rod 34, releasing the lock between the limiting rod 34 and the connecting block 32, allowing the connecting block 32 to slide along the limiting rod 34. Adjust the spacing between each punching block 33 as needed. After adjustment, rotate the handle 37 to drive the locking shaft 36 to press inward against the limiting rod 34, using friction to fix the position of the connecting block 32. The hand grip 5 can use the telescopic structure 4 to drive the adjustable punching structure 3 to press down and insert into the substrate, forming regular holes.

[0034] Reference Figures 1-5 As shown, a telescopic structure 4 is fixed to the top of the connecting frame 1. The telescopic structure 4 includes a telescopic seat 41 fixed to the middle position of the top of the connecting frame 1. A telescopic shaft 43 is provided on the top of the telescopic seat 41. Locking pieces 42 are evenly fixed on the top of the telescopic seat 41. A limit ring 45 is fixed on the outer wall of the top of the telescopic seat 41. A locking sleeve 44 is sleeved on the outer side of the telescopic seat 41 above the limit ring 45. The central axes of the telescopic seat 41 and the telescopic shaft 43 are collinear. The locking pieces 42 are evenly distributed on the top of the telescopic seat 41. The locking sleeve 44 and the locking pieces 42 are threaded together. A handle 5 is fixed to the top of the telescopic structure 4. A suspension block 6 is fixed to one side of the top of the handle 5.

[0035] Loosen the locking sleeve 44 to separate it from the locking piece 42. At this time, the telescopic shaft 43 can be pulled up and down to change its extension length, thereby adjusting the usage height of the device. After adjusting to the required height, rotate the locking sleeve 44 to re-engage it with the locking piece 42. Use the thread self-locking characteristic to fix the position of the telescopic shaft 43. When drilling, the operator holds the handle 5 and drives the drilling block 33 to press down through the telescopic structure 4. The drilling block 33 will form regular holes in the substrate, completing the drilling action.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
