Self-propelled front-mounted straw crushing and rear-mounted rotary tillage, ditching, fertilization and seeding combined operation equipment

Abstract

The invention discloses self-propelled prepositive-straw-smashing postpositive-rotary tillage ditching, fertilizing and seeding combined operation equipment and belongs to the field of agricultural machinery. The combined equipment comprises a power chassis assembly, a front suspension, a rear suspension, a straw smashing device and a finishing device, the straw smashing device is arranged in front of the power chassis assembly through the front suspension, and the finishing device is arranged in rear of the power chassis assembly; the power chassis assembly comprises a frame and crawler-type walking device, a transmission box and a driving cab assembly, the transmission box and the driving cab assembly are arranged on the frame and crawler-type walking device, and the finishing device comprises a fertilizing device, a seeding device, a rotary tillage device, a ditching device and a compacting device which are integrally mounted. The self-propelled prepositive-straw-smashing postpositive-rotary tillage ditching, fertilizing and seeding combined operation equipment integrally realizes various agricultural operations like returning smashed straw into fields, rotary tillage, fertilizing, ditching and seeding, so that working efficiency is improved greatly, and precision intelligent seeding is realized; straw is smashed and returned into the fields, so that resources are recycled, straw burning is avoided, environment is protected, and soil is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a self-propelled combined operating equipment for straw crushing and rotary tillage, ditching, fertilization and seeding. Background technique [0002] In recent years, rural crop straw has become one of the new sources of rural environmental pollution. Every summer and autumn harvest, a large amount of wheat, rice, corn and other stalks are always burned in the field, which produces a lot of smoke, causes air pollution, and even affects aviation and road transportation in severe cases. If the straw is directly discarded at the head of the field, with the arrival of the rainy season, the straw will rot and affect the water source of the ditches. Crop straw disposal has become a difficult problem in social and environmental protection. Although the government and relevant units have invested a lot of manpower and material resources in straw disposal and adopted va...

AI Technical Summary

Problems solved by technology

Although the government and relevant units have invested a lot of manpower and material resources in straw disposal and adopted various solutions, the environmental pollution caused by straw has not been well solved.

[0003] At present, farmers mostly use traditional wheeled tractor units with rear-mounted tillage machinery for operation, because traditional tillage machinery has a relatively simple structure and relatively single function, and the unit must perform repeated operations of rotary tillage, fertilization, sowing, and ditching; The repeated operation of the unit not only has low operation efficiency, but also pollutes the environment due to high energy consumption, and not only the repeated rolling of wheeled tractors causes soil compaction

In addition, traditional wheeled tractors often shake and slip, which affects the quality and efficiency of farming.

Moreover, traditional sowing devices usually cause uneven sowing, broken sowing, and missed sowing due to external soil reasons, which have a great impact on the growth of crops in the later period and affect the yield of crops.

[0004] In addition, the traditional post-mounted straw crushing and returning device, because the crushing device is located behind the driving equipment, the crops will be overwhelmed by the wheels. This caused a serious phenomenon of crops crushing between the wheel ruts, which greatly affected the crushing of crops Effect
