[0002] The furrowing device of a seed drill is mainly used to dig furrows in the soil for sowing crops. The device adapts to various soil conditions through different designs and structures to ensure that the seeds can be evenly buried at the appropriate depth. The plowshare or blade of the furrowing device is the part that directly contacts the ground and is used to cut and turn the soil. The plowshare or blade generally adopts a V-shape, a disc shape or other specific shapes to adapt to different soil types and crop requirements. The terrain in the field is undulating, and obstacles such as stones and ridges may affect the normal operation of the furrowing device, resulting in uneven furrowing depth. Since the furrowing device in the related art cannot be adjusted, inconsistent furrowing depth is prone to occur, which in turn leads to the problem of inconsistent sowing depth.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] A furrowing device for a seed drill, such as Figure 1 As shown, it includes a mounting frame 101, two mounting plates 102 and two trenching mechanisms; the two mounting plates 102 are symmetrically arranged at the ends of the mounting frame 101, and the two trenching mechanisms are symmetrically arranged on the mounting frame 101, and the trenching mechanisms can slide on the mounting frame 101; the trenching mechanism includes a guide structure, a locking structure, a suspension mechanism, a counterweight block 601, a telescopic structure, an adjustment mechanism and a trenching shovel 301, the guide structure is slidably matched with the mounting frame 101, the guide structure is connected and fixed to the mounting frame 101 through a locking structure, the suspension mechanism is arranged on the guide structure, the bottom of the suspension mechanism is connected to the telescopic structure, the top of the suspension mechanism is connected to the counterweight block 601, the bottom of the telescopic structure is connected to the trenching shovel 301, and the adjustment mechanism is used to realize the length adjustment of the telescopic structure.

[0030] like Figure 4As shown, the guide structure includes a guide sleeve 506 and a connecting plate 501. The front end surface of the guide sleeve 506 is fixedly connected to the connecting plate 501, and the connecting plate 501 is connected to the suspension mechanism. The guide sleeve 506 is slidably mounted on the mounting frame 101 and is fixedly connected to the mounting frame 101 via a locking structure. The locking structure is a locking bolt 507, which is threadedly engaged with the guide sleeve 506.

[0031] like Figure 2As shown, the suspension mechanism includes a first limiting plate 502, a second limiting plate 505, a suspension rod 503, two suspension springs, and two limiting nuts 504. The first limiting plate 502 and the second limiting plate 505 are both mounted on the connecting plate 501. The suspension rod 503 passes through the first limiting plate 502 and the second limiting plate 505. The top of the suspension rod 503 is connected to the counterweight 601, and the bottom of the suspension rod 503 is connected to the telescopic structure. The two suspension springs and the two limiting nuts 504 are both mounted on the suspension rod 503. A suspension spring is disposed on the outer side of each of the first limiting plate 502 and the second limiting plate 505. The two limiting nuts 504 are disposed between the first limiting plate 502 and the second limiting plate 505. In this embodiment, the counterweight 601 is L-shaped, and the bottom of the counterweight 601 is connected to the suspension rod 503. The suspension rod 503 runs through the first limit plate 502 and the second limit plate 505, and connects the counterweight 601 (top) and the telescopic structure (bottom). It plays the role of connecting and transmitting force, so that the weight of the counterweight 601 is evenly distributed to the trenching shovel 301. The suspension spring is set on the outside of the limit plate and is used in conjunction with the suspension rod 503. When the trenching shovel 301 is subjected to uneven ground or other resistance, the spring can provide elastic buffering, reduce the impact force on the entire device, and maintain the steady-state operation of the system. The counterweight 601 transfers gravity to the trenching shovel 301 through the suspension rod 503. During this process, the suspension spring provides elastic support, allowing the trenching shovel 301 to fine-tune the movement according to the ground conditions, thereby improving the applicability and work efficiency of the device. The limit nut 504 is installed between the first limit plate 502 and the second limit plate 505, which can effectively control the up and down movement range of the suspension rod 503 and prevent mechanical failures caused by excessive movement. By adjusting the position of the limit nut 504, the range of motion of the suspension rod 503 can be modified, indirectly adjusting the force and depth applied by the trenching shovel 301. This allows the entire system to be quickly adjusted to the optimal position under varying operating conditions. The limit nut 504 helps maintain the suspension rod 503 in the correct position, preventing overall suspension system deviation due to vibration or external forces, thereby ensuring overall stability and operational efficiency. Through the action of the suspension spring, the suspension mechanism effectively reduces vibration and impact during operation, protecting other components and extending the service life of the equipment. The suspension mechanism allows for fine-tuning of the height and position of the trenching shovel 301, allowing for easy adjustment of trenching depth and ensuring consistency and accuracy in varying terrain conditions. The automatic adjustment of the suspension structure allows for better adaptation to uneven terrain, ensuring stable trenching results even in rugged or complex terrain. The combination of the suspension rod 503 and the counterweight 601 ensures even distribution of ground pressure from the trenching shovel 301 during operation, thereby improving trenching efficiency and quality.

[0032] The telescopic structure includes a telescopic sleeve 201 and a slide rod. The top of the telescopic sleeve 201 is connected to the suspension rod 503. The slide rod slides with the telescopic sleeve 201, and the bottom of the slide rod is connected to the trenching shovel 301. The adjustment mechanism includes an electric push rod 401, a fixed base 402, and a push plate 403. The fixed base 402 is located on the outer wall of the telescopic sleeve 201. The fixed end of the electric push rod 401 is connected to the fixed base 402, and the output end of the electric push rod 401 is connected to the trenching shovel 301 via the push plate 403. The installation sleeve 302 for connecting the liquid application tube is also included and is located at the rear of the trenching shovel 301. The adjustment mechanism allows the operator to precisely control the length of the telescopic structure, thereby ensuring consistent and accurate trenching depth. Through the electric push rod 401 and other components, the adjustment mechanism can be easily automated, eliminating the need for manual operation, improving work efficiency and reducing human error. Under varying soil conditions and terrain environments, the adjustment mechanism can quickly adjust the device status to meet operational needs and ensure seeding quality.
