Description

Technical Field

[0001] The utility model relates to the technical field of line seeding devices, and more specifically, the utility model relates to a line seeding device for leafy vegetables. Background Technique

[0002] A line seeding device is a device for sowing with a seed rope. Sowing with a seed rope is a new sowing method, that is, the seeds are woven into the rope, which can save seeds. Compared with broadcasting, the seeds woven into the rope can be accurate to one seed per hole. In the case of the same number of seeds, broadcasting can only plant one mu of land, while weaving into a rope can plant four or five mu of land, saving the seed cost to the maximum.

[0003] The existing rope seeding machine (line seeding machine) generally adopts a front and rear roller wheel design. There is a high requirement for the ground flatness of the front and rear roller wheels of the drum type. When the ground is uneven, the sowing depth is inconsistent, resulting in difficult emergence.

[0004] Chinese Patent with Patent Application No. CN202322443345.1 discloses a line seeding machine for leafy vegetables, including a frame, a front roller shaft, a rear drum and a plough sleeve. The front roller shaft is horizontally arranged in the left - right direction, and its two ends are respectively connected to the front end of the frame through front shock absorbers. Walking wheels are respectively arranged at both ends of the front roller shaft. The rear end of the frame is connected with a drum frame. One end of the drum frame extends below the rear end of the frame, and the rear drum is rotatably installed at one end of the drum frame. This device effectively improves the problem that the existing line seeding machine with a drum - type front and rear wheels has a high requirement for ground flatness, and when the ground is uneven, the sowing depth is inconsistent, resulting in difficult emergence.

[0005] Then, combined with its specification drawings, it can be seen that the plough sleeve is fixed by fixing bolts to achieve the functions of grooving and sowing. Since the height of the plough sleeve is fixed, when adjustment is required, only by rotating multiple bolts one by one to loosen and then adjusting can the sowing depth be adjusted. It is inconvenient to use, and the adjustment efficiency is low, affecting the use effect. Content of the Utility Model
