Abstract

A straw feeding, chopping and scattering apparatus comprises a blower shell (5) provided with a scattering port. A feeding port (1) is arranged in the outer side of a front end plate of the blower shell; a grass rolling pressing and conveying device (2) is arranged in the feeding port; and the feeding port is communicated with the interior of the blower shell; a blower shaft penetrates the blower shell from a rear end plate of the blower shell and extends out of the front end plate of the blower shell; a movable cutter component (8) and a fixed cutter component (9) are arranged on the blower shaft inside the blower shell, and the movable cutter component comprises blower blades (85) and movable cutters (83); the fixed cutter component comprises a fixed cutter (94); the fixed cutter component is arranged on the blower shaft through a rolling bearing, and when the blower shaft rotates, the blower blades rotate with the blower shaft, and the movable cutters and the fixed cuter mutually perform cutting motion; a spiral bevel gear is arranged on the blower shaft extending out of the front end plate of the blower shell, the output roller of the spiral bevel gear is connected with a rotating-shaft box (3), and the output end of the rotating-shaft box is connected with a grass pressing roller (25) of the grass rolling pressing and conveying device via a chain transmission device.

Description

technical field [0001] The invention relates to a seeder, in particular to a straw feeding, chopping and spreading device used in conjunction with the seeder. Background technique [0002] The existing seeders mainly use the rotary tillage device to plow and bury the stubble left in the field. Firstly, it can achieve the effect of moisture conservation, heat preservation, and favorable emergence of crops. Second, after returning to the field, it can also be used as fertilizer for later crops to improve the soil. However, due to the high stubble left after rice harvesting in southern paddy fields, the soil is heavy and hardened, and it is easy to wind up rotary tiller shafts, plows and other operating tools when the soil is plowed before planting. When the soil is plowed before sowing, the entangled grass and mud of the tillage parts will greatly affect the normal operation of the seeder, and the effect of returning to the field is not good; and the complete straw decay proce...
