Description

High-density single-row precise hill-drop medicinal material seedling raising combined machine Technical Field The invention relates to the technical field of agricultural machinery, in particular to a high-density single-row precise hill-drop medicinal material seedling raising combined machine. Background The medicinal material planting is a foundation for realizing sustainable development of the traditional Chinese medicine industry, and particularly has important significance for guaranteeing medicinal material quality and market supply, and the artificial seedling raising and large-scale planting of rare traditional Chinese medicinal materials are realized. Under the background of wide application of the plastic film mulching cultivation technology, the combined operation machine for cultivating the medicinal materials is used as agricultural machinery equipment capable of realizing multi-working-operation integrated operations such as land leveling, film laying, sowing and the like, and has been rapidly popularized in main production areas of the medicinal materials in recent years. With the improvement of the land intensive management degree and the driving of the planting benefit guidance, agricultural producers put forward higher requirements on the yield per unit area, promote the development of the medicinal seedling growing planting mode to the high-density and precise directions, and expect to obtain more qualified seedlings in the limited cultivated land area. The medicinal material seedling raising combined operation machine in the prior art generally adopts a multi-row hill planter structure which is arranged in a front-back staggered way to realize multi-row planting. Specifically, limited by the radial dimensions of the dibbler itself and the installation space of the duckbill assembly, when high density planting in excess of 8-10 rows within a standard width is required, the single row arrangement cannot meet space requirements, and therefore the dibbler has to be divided into front and rear rows, for example, 6 rows for front row installation and 5 rows for rear row installation, avoiding space interference by way of front-rear misalignment. However, this construction exposes serious technical drawbacks in field operation in that the duckbill of the rear row hill planter will exert a constant frictional force on the mulch film during the soil entry and the soil exit, resulting in a slight but irreversible rearward displacement of the mulch film relative to the ground. After the rear row is sowed, the seed holes of the front row dibbler are shifted from the seed holes on the ground below the mulching film by 10-20 mm. The direct consequence is that after the seeds planted in the front row are broken into earth and emerge, the seedlings cannot normally extend out of the dislocated seed holes and are completely covered by the mulching film, so that the seedlings die due to high-temperature burn or photosynthesis resistance, namely serious 'burn-in' phenomenon is generated, and the seedling rate and planting benefit are greatly influenced. In addition, the land wheel driving mode of traditional machines is mostly unilateral land wheel power, and under the condition that high-density planting leads to seeding resistance to increase obviously, the problem of insufficient driving force, slipping and losing rotation easily appears, and then the seeding quality defects such as hole, miss-seeding and the like are caused. Therefore, the technology is urgent to develop a medicinal material seedling raising combined machine which can thoroughly eliminate the problem of dislocation of seed holes caused by displacement of mulching films while ensuring high-density planting and can provide stable and reliable seeding power so as to meet the production requirements of high quality and high efficiency of medicinal material seedling raising.
