Straw picking and crushing machine Covering compound operation machine after sowing

Abstract

The invention discloses a covering compound operating machine after sowing of a straw pick-up smashing machine. The covering compound operating machine comprises an anti-rotation straw pick-up smashing device, a conveying and throwing device and a rotary tillage, sowing and fertilizing device which are sequentially connected, and is characterized in that the conveying and throwing device comprises a grass overturning wheel capable of discharge grass, the anti-rotation straw pick-up smashing device, the conveying and throwing device and the rotary tillage, sowing and fertilizing device are a three-axis all-in-one machine, the top of the anti-rotation straw pick-up smashing device is provided with a transmission box which is connected with a pick-up smashing cutter shaft through a first transmission device, is connected with a rotary tillage cutter shaft through a second transmission device and is connected with a grass overturning wheel shaft through a third transmission device, the pick-up smashing cutter shaft is uniformly provided with a plurality of Y-shaped pick-up smashing cutters, the rotation direction of the pick-up smashing cutter shaft is opposite to the rotation direction of tractor wheels, and straws are downwards thrown onto sown soil from gaps between a plurality of groups fertilizing pipes and a seed discharging pipe through the grass overturning wheel after being smashed by the Y-shaped pick-up smashing cutters.

Description

technical field [0001] The invention relates to a straw picking and pulverizing machine and a covering compound operation machine after sowing. Background technique [0002] In recent years, during the busy farming season, the open-air burning of straw in rural areas is serious, which seriously affects the ambient air quality and endangers the physical and mental health of residents. The comprehensive utilization of straw has become a hot issue of social concern. As the most direct, most effective, and easiest to popularize and operate straw comprehensive utilization method, straw mechanized returning also has some problems. For example, due to the shallow plowing layer and the imbalance of surface soil and grass ratio in rotary tillage straw returning, the soil is suspended, the seeds of next season crops are of different depths, and the emergence of seedlings is uneven; after straw returning, the soil becomes too loose and the large pores are too large. If there are too m...

Problems solved by technology

Among them, the authorized announcement number CN202941107U, the invention name is a Chinese invention patent of a multifunctional unit for crushing straw, clearing straw, fertilizing, sowing, and covering straw. Under the mulching condition, the compound operation equipment completes the operations such as crushing straw, clearing straw, sowing, fertilizing, and covering straw after sowing at one time, but the equipment adopts the throwing method of crushed straw along the air duct and over the fertilizer box, that is, straw throwing The mouth is located above the integrated fertilization and seeding machine, and the position is relatively high. First, the power consumption of straw crushing and throwing is too large, which wastes energy; The overall structure is complex, and the production cost and operating cost are high
