Description
Technical Field
The invention relates to the technical field of hole sowing machine accessories, in particular to a horizontal speed compensation mechanism of a hole sowing machine.
Background
In some regions with poor geographical environment and water shortage, the mulching film covering technology can maximally effect temperature increase and soil moisture conservation. Most current film-mulching seeding machines adopt a mode of seeding before film laying, seedlings are placed by manual or mechanical film breaking before emergence of seedlings, operation procedures and labor intensity are increased, and the film punching seeding technology is used for punching and seeding on films, so that the seedling placing procedures are omitted. The 'autumn mulching film' and 'top-rabdosia mulching film' in northwest areas have obvious advantages compared with the traditional mulching film, and the 'autumn mulching film' is used for mulching in autumn and keeping rainfall in March (7, 8 and 9 months) for sprouting and rooting of the corn seeds in 4 months in the next year; the 'top up film covering' is to avoid soil moisture loss of the earth surface in the 'day and night freezing' process, but the seeding difficulty is larger.
At present, aiming at two film covering modes, manual or simple machinery is still generally adopted, the labor intensity is high, and the sowing qualified rate is low. The on-film sowing machine developed in China almost mainly adopts a roller type sowing machine, when shallow crops are sowed, the influence of the motion trail hypocycloid of the hole forming machine on the mulching film is small, when the crops are deep, the problems of film picking, film scraping and the like are easily caused, and the film hole cracking is aggravated by windy conditions in the northwest; meanwhile, the disturbance of the soil around the seeds is large, so that the germination period of the seeds is longer.
The direct-cutting seeding technology adopts a puncher to punch holes in the soil covered by the mulching film, and only the holes are opened to cut the mulching film, thereby being beneficial to soil moisture conservation and drought resistance. The parallel four-bar mechanism is applied to the wheat direct-insertion type film mulching hill planter in 2001 since 1993 when the parallel direct-insertion type seeding principle is firstly proposed. The present disseminator of the whole membrane mulching seeding machine for dry land corn solves the problems of high hole rate of the seeding machine, unreliable duckbill opening and the like, but the mechanism is complex and large in size, the reliability is not high, the vertical seeding of the disseminator in the seeding time period can not be realized, the horizontal speed relative to the ground is zero, and the membrane tearing phenomenon can still occur.
