Embodiment Construction

[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0013] Such as figure 1 , figure 2 , image 3 As shown, a schematic diagram of the structure of the wedge-type hollow plow for deep-layer accumulation of straw of the present invention is given, including a straw conveying auger 1, a wedge-shaped hollow plow body 2, a straw pressing wheel 3, a soil-covering disc 4, and a soil-breaking blade 5. The wedge-shaped hollow plow body 2 is that the thin-walled plates on both sides are connected and intersected forward in a streamline arc to form a vertical soil-breaking blade 5. The thin-walled plates on both sides form a cavity shape, and the rear ends of the thin-walled plates on both sides form an outer The opening is opened, and the straw pressing wheel 3 is arranged to rotate horizontally between the thin-walled plates on both sides. arc, the straw conveying auger 1 is disposed in the concave a...

Abstract

The invention discloses a straw deep-burying wedge type hollow plough, and aims to provide a straw deep-burying wedge type hollow plough which is large in straw returning amount, small in number of working procedures and higher in reliability. The straw deep-burying wedge type hollow plough comprises a straw conveying packing auger, and further comprises a wedge-shaped hollow plough body, a straw pressing wheel, earthing disks and an earth breaking cutting edge, wherein the wedge-shaped hollow plough body is a perpendicular earth breaking cutting edge formed by connecting thin-wall plates onto two sides in a forward arc surrounding manner according to a flowing line; a cavity shape is formed between the thin wall plates on two sides; the rear ends of the thin wall plates on two sides form an outward opening; the straw pressing wheel is transversely arranged between the thin wall plates on two sides in a rotatable manner; the earthing disks are arranged on the outer sides of the rear ends of the thin-wall plates on two sides in a bilateral symmetry manner; concave arcs are formed at the upper edges of the front parts of the thin-wall plates on two sides; the straw conveying packing auger is transversely arranged in the concave arcs; a lower material discharging opening of the straw conveying packing auger corresponds to the cavity. The straw deep-burying wedge type hollow plough is applicable to straw deep-burying returning work.

Description

technical field [0001] The invention relates to a straw deep-buried returning equipment, more specifically, relates to a straw deep-buried wedge-type hollow plow. Background technique [0002] Northeast China is a concentrated corn planting area with a large area and the abundance of straw resources ranks first in the country. However, the current utilization status and technological development of straw resources are not satisfactory. The relationship between the relative surplus of straw resources and the depletion of soil fertility The contradiction is becoming more and more acute. The root of the problem is that the vast majority of agricultural machinery technologies do not consider the enrichment and deep burial of straw. Secondly, the deep burial technology, which is only in the initial stage of exploration, still has many operating links and the straw travel path is long. prone to failure. Its ability to adapt to the complex farmland surface environment and the exis...
