Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an adjustable spacing tray seedling sowing device. Background Technology

[0002] Plug seedling raising is a standardized and efficient seedling raising technology in modern agriculture. The core of it is to sow a single seed in a plug with multiple independent "holes". By precisely controlling the environment (temperature, humidity, light, water and fertilizer), the seedlings grow uniformly and eventually form a robust seedling with "one seedling per hole and complete root system". This technology is widely used in vegetables, flowers, seedlings, field crops, etc., and is the core method of intensive seedling raising. It has significant advantages over traditional seedling raising (seedling pots, direct seeding in seedbeds). The prior art disclosed in patent number CN 217183785 U includes a long strip with handles at both ends and multiple perforations evenly distributed between the handles. A detachable drilling device for creating holes is inserted into each perforation, and a detachable adjustment device for adjusting the drilling depth is provided on the handle. When drilling holes in a cavity tray, the present invention requires pressing the strip by hand to insert the drilling device into the substrate of the cavity tray. Simultaneously, the handles of the strip are aligned with the side plates of the cavity tray, resulting in uniform and standardized holes. Furthermore, the adjustment device on the handle allows for adjustment of the hole depth. The aforementioned patent document discloses a seeding device for seedling tray sowing. Although the seeding device for seedling tray sowing in the aforementioned patent can adjust the depth of the holes, it is difficult to change the spacing of the holes in the actual seedling sowing process. However, different weighted crops have different requirements for the spacing of the holes, which is not conducive to the sowing device being applicable to the sowing of more crops.

[0003] In summary, there is a need for an adjustable spacing tray seedling sowing device. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0015] To address the technical problems in the background art, the following adjustable-spacing tray seedling sowing device is provided: Combination Figures 1-5As shown, this utility model provides an adjustable spacing tray seedling sowing device, including a control mechanism 3, with adjustment mechanisms 2 at both ends of the control mechanism 3, a base 1 at the bottom of the adjustment mechanism 2, and a traveling wheel 11 at the end of the base 1. Below the control mechanism 3 is an installation mechanism 4 for installing sowing components 5. The installation mechanism 4 has sowing components 5 with tray pressing holes on its side. The installation mechanism 4 includes an installation plate 41 and an installation frame 42. The installation plate 41 is located below the control mechanism 3, and the installation frame 42 is provided on the side of the installation plate 41. An installation groove is formed in the middle of the installation frame 42. The installation groove facilitates the installation of the sowing components 5 into the installation frame 42. The sowing components 5 include perforated stakes 5. 1. Assembly block 52 and assembly plate 53: The top of the drilled pile 51 is provided with assembly block 52, and the top of assembly block 52 is provided with assembly plate 53. Assembly plate 53 and assembly block 52 are L-shaped. The sowing component 5 engages and slides with the mounting frame 42. By engaging and sliding with the mounting frame 42, the position of the sowing component 5 in the mounting frame 42 can be easily adjusted, which can achieve the purpose of adjusting the spacing of the holes. At the same time, the L-shaped assembly plate 53 and assembly block 52 allow the sowing component 5 to be removed from the mounting frame 42 by rotation, which is convenient for the device to replace different sizes or install different numbers of sowing components 5, thereby making the sowing component 5 suitable for the sowing needs of more crops. In this embodiment, the installation mechanism 4 also includes a pressure plate 43, an adjusting rod 44, a connecting plate 45, and a rotating block 46. The pressure plate 43 is located inside the installation plate 41 and is used to fix the sowing component 5. The top surface of the pressure plate 43 is provided with the adjusting rod 44, and the bottom of the adjusting rod 44 is provided with the connecting plate 45. The connecting plate 45 engages with the pressure plate 43 and rotates. The adjusting rod 44 is threadedly connected to the installation plate 41, and the top of the adjusting rod 44 is provided with the rotating block 46. Through the threaded connection between the installation plate 41 and the adjusting rod 44, the pressure plate 43 can rise and fall when the adjusting rod 44 rotates. After the pressure plate 43 falls, it will press on the sowing component 5 to fix the position of the sowing component 5 and ensure that the sowing component 5 can remain stable when pressing holes in the seed tray and after adjusting the spacing. As an improvement to the above solution, the bottom surface of the pressure plate 43 is provided with anti-slip protrusions 431. The anti-slip protrusions 431 are arranged in an array and are made of elastic material, such as rubber protrusions. The anti-slip protrusions 431 arranged in an array under the pressure plate 43 can make the connection between the pressure plate 43 and the sowing component 5 more secure and can further improve the stability of the sowing component 5.

[0016] When the seedling tray sowing device is in operation, the device is placed above the seedling tray. When punching holes, the control mechanism 3 lowers the installation mechanism 4 along with the sowing components 5 to achieve hole punching in the seedling tray. During this process, according to the needs of seedling sowing and hole punching, the relative number and size of sowing components 5 can be installed in the installation frame 42 in the installation mechanism 4. Then, the sowing components 5 are controlled to move within the installation frame 42 to adjust the relative spacing of the sowing components 5. Then, the adjustment rod 44 is rotated to lower the pressure plate 43 and fix the sowing components 5. In this way, the purpose of adjusting the spacing of the seedling tray hole punching can be achieved, which is beneficial to improving the applicability of the sowing device. Example 2

[0017] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following: To enable the seeding component 5 to adjust the perforation effect, this embodiment provides the following design: The control mechanism 3 includes a horizontal plate 31, a connecting cylinder 32, a movable rod 33, and a spring 34. The bottom surface of the horizontal plate 31 is provided with the connecting cylinder 32, which is distributed in a mirror image. The movable rod 33 is provided inside the connecting cylinder 32.

The spring 34 can pull the movable rod 33 upward after it and the installation mechanism 4 have fallen, to assist the seeding component 5 in resetting. The bottom of the movable rod 33 is fixedly connected to the top surface of the installation plate 41. The control mechanism 3 also includes a pressure rod 35 and a horizontal rod 36. The pressure rod 35 engages and slides with the horizontal plate 31. The top of the pressure rod 35 is provided with the horizontal rod 36. The horizontal rod 36 and the pressure rod 35 allow the operator to control the lifting and lowering of the installation mechanism 4 and the seeding component 5 through the horizontal rod 36 and the pressure rod 35. In this embodiment, the adjustment mechanism 2 includes an adjustment plate 21, an adjustment block 22, an adjustment rod 23, a guide rod 24, and a handwheel 25. The adjustment plate 21 is located on the top of the base 1. The guide rod 24 and the adjustment rod 23 are provided inside the adjustment plate 21. The guide rod 24 engages and slides with the adjustment plate 21. The engagement and sliding of the guide rod 24 and the adjustment plate 21 can make the lifting and lowering of the adjustment block 22 more stable. The adjustment rod 23 is threadedly connected to the adjustment plate 21. The adjustment rod 23, which is threadedly connected to the adjustment plate 21, can change the height of the adjustment block 22 when rotating, thereby changing the height of the control mechanism 3, the installation mechanism 4, and the seeding component 5.
