Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a wheat breeding and sowing fixed-distance pit digging mechanism. Background Technology

[0002] Wheat is one of the core crops supporting global food security, possessing value in terms of food, economy, and culture. It is highly adaptable to planting, with diverse varieties. Through continuous advancements in agricultural technology, its yield and quality have been constantly improving, making it a crucial material foundation for human societal development. Sowing density and hole spacing are key agronomic parameters: uniform spacing avoids competition for light, water, and nutrients, ensuring robust individual development; consistent hole depth provides a stable soil environment for seed germination, increasing emergence rates. Therefore, developing high-precision, adaptive sowing and hole-digging mechanisms is essential for achieving high and stable wheat yields.

[0003] Existing wheat breeding and sowing spacing digging mechanisms mainly achieve spacing digging by digging holes at equal intervals around a roller. The core principle is to use a fixed or adjustable shovel head to complete the soil entry operation as the roller rotates. However, most existing shovel heads are rigidly fixed on the roller. When the shovel head hits obstacles such as stones or branches during high-speed rotation, the instantaneous impact force can easily cause the shovel head to deform or break. If branches get tangled in the shovel head, it will prevent the shovel head from entering the soil, resulting in missed sowing. Therefore, it has certain limitations. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] According to one embodiment of the present invention, in conjunction with Figure 1-3 As shown. A wheat breeding and sowing fixed-distance hole-digging mechanism includes: a mobile trolley 1, an intercepting plate 2 is provided on the front of the bottom of the mobile trolley 1, multiple intercepting rods 3 are fixedly installed at the bottom end of the intercepting plate 2, and mounting shafts 4 are fixedly installed at both ends of the intercepting plate 2. Threaded sleeves 5 are fixedly installed on both sides of the mobile trolley 1, and screws 6 are threadedly connected to the inner walls of the two threaded sleeves 5. The bottom of the two screws 6 is threadedly connected to the inner threads of the mounting shafts 4 and the bottom threads are connected to nuts 7. The tops of the two nuts 7 are in contact with the bottom ends of the adjacent mounting shafts 4.

[0018] In this embodiment, by using the interception rod 3 in conjunction with the interception plate 2, large rocks, tree branches and other obstacles on the ground can be effectively intercepted before the digging shovel 17 starts working, so as to prevent them from directly hitting the digging shovel 17, reduce damage to the shovel head, improve the durability of the mechanism and ensure the smooth progress of subsequent digging operations.

[0019] Reference Figure 2 An installation sleeve 9 is fixedly installed on the top of the back of the interceptor plate 2. A reciprocating screw 10 is rotatably installed inside the installation sleeve 9. A micro motor 14 is fixedly installed on one end of the inner wall of the installation sleeve 9. The output end of the micro motor 14 is fixedly connected to one end of the reciprocating screw 10. A threaded movable sleeve 11 is threadedly connected to the outer wall of the reciprocating screw 10. A connecting rod 12 is fixedly connected to the bottom end of the threaded movable sleeve 11. A sliding groove 8 is opened in the middle of the interceptor plate 2. The connecting rod 12 passes through the sliding groove 8 and a scraper 13 is fixedly connected to one end of the connecting rod 12. The scraper 13 is in contact with the front of the interceptor plate 2.

[0020] In this embodiment, the micro motor 14 drives the reciprocating lead screw 10 to rotate, which in turn drives the threaded movable sleeve 11, the connecting rod 12 and the scraper 13 to move back and forth, clearing obstacles on the interception plate 2 in a timely manner, preventing accumulation, ensuring the continuous normal operation of the interception mechanism and maintaining a stable working environment.

[0021] Reference Figure 1 Both sides of the bottom of the mobile trolley 1 are fixedly installed with extension rods 15. A rotating rod 16 is rotatably installed on the inner wall of the extension rod 15. Multiple digging shovels 17 are symmetrically fixedly sleeved on the outer wall of the rotating rod 16. A drive motor 18 is fixedly installed on the outer wall of one of the extension rods 15. The output end of the drive motor 18 is adjacent to the extension rod 15 and fixedly connected to one end of the rotating rod 16.

[0022] In this embodiment, the drive motor 18 drives the rotating rod 16 and the digging shovel 17 to rotate, thereby achieving fixed-distance digging, ensuring uniform sowing spacing, facilitating the rational allocation of resources during wheat seed growth, and improving sowing quality and uniformity of wheat seedling growth.

[0023] Reference Figure 1 The back of the rotating rod 16 is provided with a baffle 19, and the top of the baffle 19 is fixedly connected to the bottom of the moving trolley 1.

[0024] In this embodiment, the baffle 19 can prevent debris from approaching the rotating rod 16, reduce interference with the rotation of the rotating rod 16, enhance the stability of the mechanism, and ensure that the digging operation is continuous and accurate.

[0025] Working principle: The mobile trolley 1 acts as a carrier, moving through the wheat field. The intercepting plate 2 and intercepting rod 3 on the bottom front first contact the ground surface, initially intercepting obstacles such as large rocks and branches to prevent them from directly impacting the digging mechanism behind. When the intercepting plate 2 intercepts an obstacle, the micro motor 14 inside the mounting sleeve 9 starts, driving the reciprocating screw 10 to rotate. Because the threaded movable sleeve 11 reciprocates with the reciprocating screw 10, the connecting rod 12 drives the scraper 13 to move synchronously back and forth within the chute 8, thus removing the obstruction from the intercepting plate. Obstacles on plate 2 are scraped off and cleared to prevent accumulation from affecting subsequent interception effects. At the same time, the drive motors 18 on the extension rods 15 on both sides of the bottom of the moving trolley 1 drive the rotating rod 16 to rotate. Multiple digging shovels 17 fixedly sleeved on the outer wall of the rotating rod 16 rotate synchronously with the rotating rod 16 to achieve fixed-distance digging operation and ensure uniform sowing spacing. Subsequently, by rotating the nuts 7 on both sides of the moving trolley 1, the extension length of the screw 6 in the threaded sleeve 5 and the mounting shaft 4 can be adjusted, thereby flexibly adjusting the installation angle and position of the interception plate 2 to adapt to different terrains and soil conditions.

[0026] 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.
