Description

Technical Field

[0001] This utility model relates to the field of seeding device technology, and in particular to a seeding device with adjustable planting depth. Background Technology

[0002] In agricultural production, sowing is a crucial initial step, and its quality directly affects the germination rate, growth status, and final yield of crops. Sowing depth, as a key parameter in the sowing process, has a profound impact on seed germination and seedling growth.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: different crops have different requirements for sowing depth, and soil conditions also affect sowing depth. In clay soil, the sowing depth may need to be appropriately shallow to avoid the seeds suffocating due to poor soil aeration, while in sandy soil, it may need to be appropriately deep to prevent the seeds from drying out due to excessive water evaporation. However, existing sowing devices cannot effectively adjust the planting depth, making it difficult to meet the diverse needs of different crops and soil conditions. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing technology has the disadvantage of poor adaptability to different crops and soil conditions. To address this, we propose a sowing device with adjustable planting depth.

[0005] To achieve the above objectives, this application adopts the following technical solution: a planting device with adjustable planting depth, comprising a planting device body, an adjustment groove inside the planting device body, an adjustment column rotatably connected inside the adjustment groove, a furrowing rod inside the adjustment column, a planting mechanism at the rear end of the furrowing rod, several adjustment holes on both sides of the furrowing rod, a control groove on both sides of the adjustment column, a push block slidably connected inside the control groove, an insert rod fixedly connected to the side of the push block near the inside of the control groove, and arc-shaped blocks fixedly connected to both sides inside the adjustment groove.

[0006] Preferably, the size of the insertion rod is adapted to the size of the adjustment hole, and the surface of the insertion rod is inserted into the interior of the adjustment hole.

[0007] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the control groove.

[0008] Preferably, guide grooves are provided at both ends of the control groove, and guide blocks are fixedly connected to both ends of the push block, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0009] Preferably, the inner wall of the adjusting groove is fixedly connected to two ring blocks, and the outer diameter surface of the adjusting column is provided with two ring grooves.

[0010] Preferably, limiting grooves are provided on both sides of the adjusting column, and limiting rods are slidably connected inside the limiting grooves. Limiting holes are provided on both sides of the planting device body. A thrust spring is fixedly connected to the side of the limiting rod near the inside of the limiting groove, and the side of the thrust spring away from the limiting rod is fixedly connected to the inside of the limiting groove.

[0011] Preferably, both ends of the limiting groove are provided with sliding grooves, and both ends of the limiting rod are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the worker moves the trenching rod downwards to a suitable position. After adjusting to the suitable position, the worker rotates the adjusting column, causing the adjusting column to drive the push block to contact the thicker end of the arc-shaped block. The arc-shaped block then pushes the push block to insert the insertion rod into the position of the adjusting hole, thus limiting the position of the trenching rod and adjusting the trenching depth.

[0021] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a seeding device with adjustable planting depth, including a planting device body 1, an adjustment groove 2 is provided inside the planting device body 1, an adjustment column 3 is rotatably connected inside the adjustment groove 2, a furrowing rod 4 is provided inside the adjustment column 3, a seeding mechanism 5 is provided at the rear end of the furrowing rod 4, a plurality of adjustment holes 6 are provided on both sides of the furrowing rod 4, a control groove 7 is provided on both sides of the adjustment column 3, a push block 8 is slidably connected inside the control groove 7, an insertion rod 9 is fixedly connected to the side of the push block 8 near the inside of the control groove 7, and an arc-shaped block 10 is fixedly connected to both sides inside the adjustment groove 2.

[0023] Specifically: The worker moves the trenching rod 4 downwards to the appropriate position. After adjusting to the appropriate position, the worker rotates the adjusting column 3, causing the adjusting column 3 to drive the push block 8 to contact the thicker end of the arc block 10. The arc block 10 then pushes the push block 8 to drive the insertion rod 9 into the position of the adjusting hole 6, thus limiting the position of the trenching rod 4 and adjusting the trenching depth.

[0024] Reference Figure 2 and Figure 5 As shown, in this embodiment: the size of the insertion rod 9 is adapted to the size of the adjustment hole 6, and the surface of the insertion rod 9 is inserted into the interior of the adjustment hole 6;

[0025] Specifically: After the insertion rod 9 is inserted into the adjustment hole 6, a relatively stable connection can be formed, ensuring that the furrowing rod 4 will not easily shake or shift after being adjusted to the correct position, thereby ensuring the stability of the furrowing depth during the operation of the sowing device.

[0026] Reference Figure 5As shown in this embodiment: a storage spring 11 is fixedly connected to the side of the push block 8 near the insertion rod 9, and the side of the storage spring 11 away from the push block 8 is fixedly connected to the inside of the control groove 7.

[0027] Specifically: When the arc-shaped block 10 pushes the push block 8 to drive the insertion rod 9 into the adjustment hole 6, the storage spring 11 will be compressed to generate elastic force. When it is necessary to readjust the position of the trenching rod 4, this elastic force can help the push block 8 and the insertion rod 9 to quickly reset, making it easier to carry out the next adjustment operation, thus improving the convenience and flexibility of the device adjustment.

[0028] Reference Figure 5 As shown in this embodiment: guide grooves 12 are provided at both ends of the control groove 7, and guide blocks 13 are fixedly connected to both ends of the push block 8. The surface of the guide block 13 is slidably connected to the inside of the guide groove 12.

[0029] Specifically, the combined use of guide groove 12 and guide block 13 provides precise guidance for the movement of push block 8 within control groove 7. Thus, when arc block 10 pushes push block 8, push block 8 can move smoothly along guide groove 12, avoiding deviation or jamming of push block 8 during movement. This ensures that insertion rod 9 can be accurately inserted into adjustment hole 6, further improving the accuracy and stability of device adjustment.

[0030] Reference Figure 2 and Figure 4 As shown in this embodiment: two ring blocks 14 are fixedly connected to the inner wall of the adjusting groove 2, and two annular grooves 15 are opened on the outer diameter surface of the adjusting column 3;

[0031] Specifically: the ring block 14 and the ring groove 15 are adapted to each other. When the adjusting column 3 moves up and down in the adjusting groove 2 to adjust the planting depth of the trenching rod 4, the ring block 14 will slide along the ring groove 15. This design provides a stable limit and guide for the movement of the adjusting column 3, preventing the adjusting column 3 from shaking or deviating during the movement.

[0032] Reference Figure 4 and Figure 5 As shown, in this embodiment: limiting grooves 16 are provided on both sides of the adjusting column 3, and limiting rods 17 are slidably connected inside the limiting grooves 16. Limiting holes 21 are provided on both sides of the planting device body 1. A thrust spring 18 is fixedly connected to the side of the limiting rod 17 near the inside of the limiting groove 16, and the side of the thrust spring 18 away from the limiting rod 17 is fixedly connected to the inside of the limiting groove 16.

[0033] Specifically: After the operator locks the position of the grooved rod 4 by rotating the adjusting column 3, the position of the limiting groove 16 is parallel to the position of the limiting hole 21, and under the action of the rebound force of the thrust spring 18, the limiting rod 17 is quickly pushed into the interior of the limiting hole 21, thus completing the locking of the adjusting column 3.

[0034] Reference Figure 5 As shown in this embodiment: both ends of the limiting groove 16 are provided with sliding grooves 19, and both ends of the limiting rod 17 are fixedly connected with sliders 20, and the surface of the sliders 20 is slidably connected to the inside of the sliding grooves 19.

[0035] Specifically: When the limiting rod 17 slides inside the limiting groove 16, the slider 20 will slide along the inside of the sliding groove 19. This design can further ensure the stability of the movement of the limiting rod 17 and prevent it from getting stuck or deviating during the sliding process. This allows the limiting rod 17 to be inserted into the limiting hole 21 more smoothly, thereby more reliably locking the adjusting column 3 and ensuring the stability and reliability of the entire sowing device after adjusting the planting depth.

[0036] Working principle: The operator moves the trenching rod 4 downwards to the appropriate position. After adjusting to the appropriate position, the operator rotates the adjusting column 3, which causes the adjusting column 3 to drive the push block 8 to contact the thicker end of the arc block 10. The arc block 10 then pushes the push block 8 to insert the insertion rod 9 into the position of the adjusting hole 6, thus limiting the position of the trenching rod 4 and adjusting the trenching depth.

[0037] 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.
