The upper surface of the arc-shaped adjustment seat is provided with a vertically penetrating arc-shaped adjustment hole, and the end of the arc-shaped adjustment seat is inserted into the support groove.

[0013] To better realize this utility model, the first plowing assembly further includes a first adjusting cylinder, the top of the first adjusting cylinder is fixedly connected to the bottom of the first connecting seat, a first locking cylinder is provided on the bottom side wall of the first adjusting cylinder and communicates with the inner cavity of the first adjusting cylinder, a first mounting hole is opened on the top surface of the first locking cylinder and communicates with the inner cavity of the first locking cylinder, a first pull rod is sleeved in the first mounting hole, a first pull rod head is provided at the end of the first pull rod away from the first adjusting cylinder, a first locking head is provided at the end of the first pull rod near the first adjusting cylinder, and a first spring is sleeved on the part of the first pull rod located between the first locking head and the inner top surface of the first locking cylinder;

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] 1. This utility model, through the design of fine-tuning connectors, makes the entire morel mushroom soil trenching and sowing device more flexible.

[0019] 2. This utility model can improve overall flexibility and adaptability to different terrains: The roller assembly of the device can be vertically slidable and adjusted on the front side of the support frame. It can slide within the vertical installation opening through the adjustment rod according to the flatness of different fields and be fixed by the locking head. The height of the roller can be flexibly adjusted to ensure that the device can move stably on uneven ground, improve the adaptability to different terrains, and ensure the smooth progress of furrowing and sowing.

[0020] 3. This utility model can meet the needs of edge operations: the design of the fine-tuning connector and the second plowing component makes the device highly flexible when turning soil at the edge of the field. When encountering obstacles such as field ridges, the circular sliding block can be slid along the arc-shaped adjustment hole to fine-tune the position of the second plowing component, change the relative position of the first and second plows and the included angle between the two second plows, thereby better adapting to the complex terrain at the edge of the field and effectively solving the limitations of traditional ditching devices when operating at the edge.

[0021] Precise adjustment of trenching depth

[0022] 4. This utility model provides a convenient height adjustment mechanism: both the first and second plowing components employ a combination of pull rods, locking heads, and springs for adjustment. By pulling the first or second pull rod, the first or second locking head disengages from its corresponding locking hole, easily allowing the first or second telescopic rod to move up and down, thus conveniently adjusting the height of the first and second plows. After adjusting to the appropriate position, releasing the pull rod causes the spring force to re-engage the locking head into the locking hole, achieving rapid locking. This design is not only easy to operate but also allows for precise control of the trenching depth, meeting the soil trenching depth requirements for different morel mushroom cultivation methods.

[0023] The connection is secure and the installation is easy.

[0024] 5. This utility model achieves a reliable connection structure: the fixed connector and the fine-tuning connector are tightly connected to the support frame body via U-shaped parts and nuts, ensuring the stability of the first and second plowing components during operation. The first and second U-shaped parts pass through the through holes on the first and second connecting seats respectively and are locked by nuts, making the connecting seats fit tightly against the lower surface of the support frame body, effectively preventing the plowing components from shaking or shifting during ditching, and ensuring the accuracy and quality of ditching operations.

[0025] 6. This utility model facilitates connection with a tractor: the mounting bracket on the upper surface of the support frame can be easily connected to the tractor through its fixing holes, enabling power drive of the device. This connection method is simple and reliable, allowing operators to quickly install and disassemble the device, thus improving work efficiency.

[0026] Structural optimization and cost-effectiveness

[0027] 7. This utility model achieves a reasonable structural layout: the design of the support frame fully considers the overall structural and functional requirements of the device. The vertical mounting openings, limiting notches, lugs, support platforms, and other structures provided on the support frame body provide reasonable installation positions and adjustment space for components such as roller assemblies, fixed connectors, and fine-tuning connectors, making the entire device compact and rationally laid out, reducing the floor space and manufacturing costs.

[0028] 8. This utility model achieves component versatility and maintainability: the first and second plowing components have certain structural similarities, and some parts, such as the pull rod, locking head, and spring, have high versatility, reducing the production and management costs of parts. At the same time, this modular design facilitates maintenance and replacement of parts when the device malfunctions, improving the maintainability and service life of the device.

The bottom of the second telescopic rod 610 is provided with a second plow 612.

[0067] Both the first plowshare 509 and the second plowshare 612 utilize existing mature technologies with soil-covering capabilities. Of course,

[0068] Working principle:

[0069] Place the roller 202 and the first plow 509 and the second plow 612 of this device on the ground, and then connect them to the tractor through the fixing holes of the mounting bracket 102.

[0070] In use, the rollers 202 roll to create furrows using the first plow 509 and the second plow 612. Adjustments to the height of the first plow 509 and the second plow 612 are made by pulling the first lever head 504 and the second lever head 607, respectively. Specifically, pulling the first lever head 504 and the second lever head 607 outwards causes the first locking head 505 and the second locking head 608 to move outwards, compressing the first spring 506 and the second spring 609. The first locking head 505 and the second locking head 608 then emerge from the first locking hole 508 and the second locking hole 611, respectively, allowing the first telescopic rod 507 and the second telescopic rod 610 to move up and down. After reaching the desired position, releasing the first lever head 504 and the second lever head 607 locks the rod in place.

[0071] When tilling the soil at the edge of the field, due to obstacles such as field ridges, it is necessary to finely adjust the second plowing component 600 along the sliding direction of the arc-shaped adjustment hole 405 to adjust the relative position of the first plow 509 and the second plow 612 to meet the actual needs. After adjusting and sliding the circular sliding block 602 within the arc-shaped adjustment hole 405, the circular sliding block 602 is locked by the threaded connection of the locking seat 603, the locking rod 604, and the second locking hole 108, thereby adjusting the position of the second plow 612. As a result, the angle between the line connecting the two second plows 612 and the line connecting one of the first plows 509 and any one of the second plows 612 increases or decreases to meet the tilling needs at the edge of the field.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
