A thirty-six row large folding cotton planter

Abstract

This utility model discloses a 36-row large-scale folding cotton seeder, belonging to the field of cotton seeder technology. It aims to solve the problems of insufficient efficiency of existing cotton seeders for large-scale field planting due to the promotion of large-scale cotton planting models. Furthermore, existing seeders require manual supervision to monitor the seeding quality and change drip irrigation tape rolls, resulting in high labor intensity and costs. The key technical points of this solution include a frame with a central beam fixedly connected to its rear end. Side beams are movably connected to both ends of the central beam. Hydraulic push rods are hinged to the outer side of the frame, with their movable ends hinged to the side beams. The side beams are movably connected to the frame via the hydraulic push rods, and side wheels are movably connected to the side beams away from the frame. This achieves the effects of folding and transporting, independent double-row contouring, manual monitoring while following the machine, and non-stop drip irrigation tape replacement.

During operation, the beam buckle 18 opens, the hydraulic push rod 2 extends, the side beam 11 unfolds, and after being flattened, the middle travel wheel push rod 12 and the side travel wheel push rod 13 extend, the middle travel wheel body 3 and the side travel wheel 4 are lifted, and the seeding device 5 falls down to contact the ground and begins operation.

[0034] Meanwhile, the height-limiting wheel 503 levels the land in front, the scraper assembly 504 digs shallow trenches, the drip irrigation tape is laid from the drip irrigation tape reel frame 6 under the drip irrigation tape mounting frame 19 through the drip irrigation tape laying wheel 505 into the field, and then leveled by the drip irrigation tape pressing wheel 506 and lightly covered with soil. Cotton seeds enter the seed metering device 507 from the seed box body 502 through the pipe, and the seed metering device 507 then inserts the seeds into the field to complete the sowing operation. The four-bar linkage contour mechanism 501 can adjust the working height according to the undulation of the ground to ensure the consistency of the sowing depth.
