Description

Film-laying hill planter

Technical Field

The invention relates to an agricultural film-laying seeder, in particular to a film-laying hill-drop planter.

Background

At present, most film-spreading hill-drop planters can finish multiple compound operations of land leveling, under-film fertilization, pipe-spreading and film-spreading, film-edge earthing, on-film hill-drop, seed hole earthing and the like at one time in the process of hill-drop operation. The different side points of the machines produced by various companies in consideration of various operations cause great differences of the machine structures, so that various problems generally occur when the multiple operations are completed at one time, and some problems caused by the structure are serious and have universality. The severity of the problem is typically as follows: 1. seed "filming" problem: namely, the dislocation of the film pressing opening film breaking hole on the film and the underground hole sowing hole during hole sowing operation causes the covering of the seeds by the mulching film, the seeds are covered under the film after germination and need to be manually broken and put into seedlings, and the phenomenon is called 'film drilling'. The hole sowing device with the film pressing ring and the hole sowing roller which are designed into a whole has the problem of 'film drilling' in different degrees in the film laying process, firstly, the hole sowing device is simultaneously carried out on the film pressing ring for pressing the film edge and the film breaking hole sowing operation of the pressing nozzle, the film edge soil covering operation is carried out immediately thereafter, and the soil covering operation immediately thereafter easily causes the dislocation of the film breaking hole of the pressing nozzle on the unfixed mulching film and the underground seeding hole; secondly, if the earthing condition of the earthing disc is not adjusted properly, the earthing disc and the earthing disc can generate thrust or crush the film edge to the mulching film to be fixed by earthing the film edge so that the film pressing mouth breaks the film hole and the seed hole are greatly staggered, thereby causing serious 'film drilling'. 2. Uneven soil sealing of seed holes or unstable soil covering quality: the soft and hard of the cultivated ground hole-sowing layer are different due to different soil qualities in the same land to be sowed, and when the soil covering disc just covers soil on the hard ground, the soil covering amount on the seed holes is large when the soil enters the soft ground, so that the seeds are easy to not emerge; on the contrary, when the soft ground is just covered with soil and enters the hard ground, the soil covering amount of the seed holes is insufficient or even no soil is covered, so that the cost of manual supplement operation is increased; 3. many problems occur when the broadcast area is slightly abnormal, and the general adaptability is poor: if the slope of the land to be sowed is larger or not flat, the mulching film cannot be spread and the film spreading and soil covering amount is seriously uneven; when the land is too loose, the hill planter can crush the mulching film; when the soil blocks are slightly large or stones exist, the mulching film laying and earthing quality is poor, and the mulching film is easy to damage; when weeds and stubbles are slightly more, the furrow opener is easy to wind the grass, so that the problems of poor film laying and ditching quality, poor film laying and soil covering quality, poor seed hole and soil covering quality and the like are caused.
