Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly relates to a amphibious straw smashing and throwing machine.

Background

Nowadays, the straw machine or the straw throwing machine is popularized in the original region for many years, the technology is mature, and the field in the original region is mostly in a 'flat ground' cultivation mode, so that the difficulty is low compared with the traditional field returning. However, in the last year, with the burning prohibition of the straws in the northeast (Liaoning, Jilin and Heilongjiang), a large amount of straws in the fields and paddy fields in the northeast cannot be treated, and only the straws are returned to the field or leave the field. As the field in the northeast region is operated on ridges, a large number of traditional straw mills are sent to the northeast in the last year, but the traditional straw mills can only break the straws on the ridges and return the straws to the field, which does not play a role in the straws in the furrows, and the field is only aimed at ridge culture. A large number of paddy fields (the planting condition of paddy fields is basically the same as that of the original regions, the paddy fields are all flat, and only crops are planted differently) in northeast China also need to be crushed and thrown. A plurality of users often need to purchase two straw returning machines, namely a straw returning machine for dry farmland and a straw throwing machine for paddy field, and the two straw returning machines are not good for use.
