Machine used for rotary tillage, seeding, straw smashing and straw mulching returning

Abstract

The invention relates to a machine used for rotary tillage, seeding, straw smashing and straw mulching returning. A tractor drives an intermediate transmission case (3) and a side transmission case (4) through a cardan joint (2) to drive a main belt wheel (23) to rotate. The main belt wheel drives a transmission belt wheel (21) to rotate through a belt (22) to drive a rotary blade shaft (24) and a smashing blade shaft (25) to work. A land wheel drives a driving chain wheel (114) to rotate. The driving chain wheel drives a transmission chain wheel (111) to rotate through a chain (112) to drive a seed discharging shaft (110) and a fertilizer discharging shaft (5) to rotate. Seeds fall into a seed conveying pipe (116) and fall onto land which is already cultivated. Smashed straw is blown by wind produced by fan blades (119) to a front opening end of a straw conveying cavity (113), is blown backwards and then falls onto the surface of the land through a rear opening end of the straw conveying cavity. The land wheel performs compaction on the surface of the land which is already subjected to rotary tillage, seeding and fertilizing. In this way, the machine can complete the working procedures of rotary tillage, fertilizing, seeding, straw smashing, straw mulching returning and compaction at a time.

Description

technical field [0001] The invention relates to a field-returning machine, in particular to a field-returning machine for rotary tillage, sowing, straw crushing and covering, and belongs to the technical field of agricultural machinery. Background technique [0002] With the improvement of the degree of agricultural mechanization, rotary tillers, ditchers, and fertilizer spreaders are widely used in the field of agricultural land preparation, which fundamentally liberates the hands of farmers, improves operating efficiency, and reduces labor costs. [0003] However, the straw returning machine and rotary tillage seeder currently used in our country are single operations, with few processes. The straw needs to be crushed first, and then the rotary tillage sowing and fertilization operations are performed. The operation efficiency is low, the energy consumption is high, the production cost is high, and all straw is buried. Into the soil, is not conducive to seed germination an...
