Full-straw burying tillage fertilizing seeder

Abstract

The invention discloses a full-straw burying tillage fertilizing seeder, and relates to an agricultural composite working machine. The full-straw burying tillage fertilizing seeder comprises a stander, a rotary tillage device, a fertilizing and seeding device and a power device, and is characterized in that at least two mutually separated guide plates arranged back and forth are arranged between a knife roll and a seeding shoe, the underside edges of the guide plates are lowered in turn from the front to back, the left end and the right end of each guide plate are arranged on longitudinal support bars fixed on the stander, the mounting places are preferably hinged, and the positions of the guide plates are adjusted by an adjusting rod and a bolt. An inclination angle alpha of the guide plates and the vertical direction is 10 to 70 degrees, and preferably the alpha is reduced in turn from the front to the back. The full-straw burying tillage fertilizing seeder is used for farmland, particularly dry land work; because of the matching action of a rotary cutting stubble-burying cutter and the guide plates, the seeder can finish multi-work of tilling, burying, fertilizing and seeding; and particularly, thrown soil is guided layer by layer by the guide plates and falls gradually, so the full-straw burying effect is ensured, and the proper fertilizing and seeding depth and even flatness of a soil coverage layer are also ensured.

Description

technical field [0001] The invention relates to a farmland plowing machine, in particular to a compound operation machine which implements fertilization and seeding while plowing the land and covering and burying straw during dry farming. Background technique [0002] In order to play the role of environmental protection, time-saving, cost-saving, and efficiency-enhancing, farmland plowing needs to complete multiple operations such as plowing, burying straw, crushing soil, leveling, sowing, and fertilizing. This is especially important for plowing machinery. It is dry land tillage machinery that puts forward higher and higher requirements. Invention patent 2004101030941 discloses a stubble burying machine, which is mainly used for paddy field cultivation. It can complete multiple operations of plowing, crushing soil, pulping, and covering straw at one time, effectively returning straw to the field, but it cannot be used for dry land covering. After burying the straw, fertil...
