Dual-drive type on-film hole opening and seed sowing device and method

Abstract

The invention provides a dual-drive type on-film hole opening and seed sowing device and method, and relates to the field of film mulching planting. The dual-drive type on-film hole opening and seed sowing device comprises a rack, a first suspension, a disc and a second suspension, the first suspension, the disc and the second suspension are sequentially arranged on the rack, the disc is rotatablyinstalled on the rack, and a hole opening mechanism is matched with the annular edge of the disc; the rack is provided with a cam and a seed discharging device of the hole opening mechanism, the camand the seed discharging device are matched with driving mechanisms, when the hole opening mechanism rotates around the axis of the disc to the position matched with the cam, the hole opening mechanism is opened towards the side away from the end face of the disc to form a seed feeding opening communicated with a seed feeding cavity in the hole opening mechanism, and a rotary disc can be driven toachieve active transverse hole opening at different rotating speeds, and the seed discharging device is driven in a matched manner to output at different speeds, so that the operation requirements ofdifferent row spacings are met; and in addition, the hole opening mechanism can achieve transverse hole opening in the direction perpendicular to the walking direction, a film breaking area is reduced, the phenomena of film tearing and film pulling can be reduced, on-film high-speed precision seeding is achieved, and the problems that hole opening depths are not equal due to different ridge typesof single-ridge operation are solved.

Description

technical field [0001] The present disclosure relates to the field of film-covered planting, in particular to a dual-drive type film-opening hole-seeding device and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, sowing on mulch is widely used, and mulching cultivation has significant effects such as heat preservation, moisture conservation, early maturity of crops, and yield increase. In addition to artificial planting, people also use some simple mulching machines, which are generally small, simple in structure, and single-function mulching machines. During use, manual assistance is needed for fertilization, ridging, ditching, sowing, Spraying, mulching and other repeated labor can be completed. Generally, one row or two rows are planted in one ridge. The work efficiency is low and the labor intensity is high. It i...

Problems solved by technology

[0005] The purpose of this disclosure is to address the defects of the existing technology, and to provide a double-drive type hole-opening seeding device and method on the membrane, which can drive the turntable to realize active horizontal hole opening at different speeds, and cooperate with the drive of the seed meter to output at different speeds. It meets the operation requirements of different plant distances, and the hole opening mechanism can realize horizontal hole opening perpendicular to the walking direction, which reduces the area of ​​membrane rupture, reduces the phenomenon of tearing and tearing the membrane, realizes high-speed and precise seeding on the membrane, and solves the problem of single ridge operation Uneven hole depth caused by different ridge types
