A straw throwing and overturning combined operation machine

Abstract

The invention relates to the field of agricultural equipment, in particular to a straw throwing and burying combined machine. The combined machine comprises a burying device (1), a hanging device (3),a throwing device (9) and a power transmission device (12). A vertical rotation mode is adopted by the throwing device (9) of the combined machine according to a tedding machine principle, and underthe action of centrifugal force, straw is thrown to the two sides; air flow is formed between adjacent throwing mechanisms (14), so that the straw throwing range is further expanded. When the combinedmachine goes to the field once, straw throwing work and straw burying work can be completed at the same time; meanwhile, the burying device (1) at the rear end of the combined machine can be removedso that separate straw throwing operation can be achieved, and moreover, combined operation of the throwing device (9) and a land preparation machine without power drive, such as a disc plough and a disc harrow, can be achieved through adjustment, the number of times for the machine to go to the field is reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a straw throwing and overturning combined operation machine. Background technique [0002] The first-ripe rice area in the north is an important rice-producing area in my country and plays an important role in maintaining national food security. The yield of rice in a mature rice area in the north is high, but due to long-term over-cultivation and cultivation, heavy use and low cultivation, and excessive application of chemical fertilizers, the soil structure is destroyed, organic matter is decomposed and mineralized, and soil fertility is seriously degraded; at the same time, straw burning causes environmental pollution. All these seriously threaten the sustainable development of the rice-growing areas in the north. In recent years, although researchers and farmers have recognized the importance of straw returning to the field, the proportion of straw returning to the fiel...

Problems solved by technology

However, the combine harvester has the phenomenon of uneven crushing and scattering of straw, and the straw is easy to form agglomerates, which affects the field preparation and transplanting.

Using the straw crushing and returning machine for secondary crushing and returning to the field solves the problem of piles and uneven distribution of straw, but the secondary crushing into the field will cause compaction of the soil and a large amount of energy consumption, which is not suitable for large areas of the first mature rice area in the north. paddy field work
