Rice field shallow ploughing machine

Abstract

A rice field shallow ploughing machine comprises a bevel gear box, a three-point suspension, a rack, a lateral supporting shaft box, a shallow ploughing assembly and a lateral transmission box, wherein the three-point suspension is hung on the rack and the bevel gear box respectively and rapidly hung on each power machine head; power is transmitted by a tractor PTO output device to the bevel gear box; the bevel gear box transmits the power to the lateral transmission box; one end of the shallow ploughing assembly is connected to the lateral transmission box, and the other end is connected to the lateral supporting shaft box; the lateral transmission box transmits the power to the shallow ploughing assembly so as to drive motion of the shallow ploughing assembly; and the lateral supporting shaft box is used to support the shallow ploughing assembly. According to the invention, shallow ploughing cutter tooth sets which are arranged in a grouped and spiral manner are used for shallow ploughing and soil loosening of the surface layer of a rice field and ground leveling; the shallow ploughing cutter teeth only work on the superficial soil, so the consumption power is low, and working efficiency is high; a power output device is extended on the rack, so a transplantation mechanism can be integrated easily, and further integral operations of shallow ploughing and plantation can be achieved; and the applicable scope is wide.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a paddy field shallow tillage machine. Background technique [0002] In terms of rice planting, regardless of direct seeding or transplanting, the root-to-shoot ratio, dry weight of single root root, total root absorption surface area, and active absorption surface area of ​​no-tillage rice at the highest tillering stage are all higher than those of tillage rice. The root weight, root weight density and root length of 5-10cm and 10-20cm soil layers were higher than those of plowed rice. Under transplanting conditions, the root length, root length density and root surface area of ​​the 0-5cm soil layer in the no-tillage rice maturity stage were higher than those of the tillage rice, and the total root absorption and root system oxidative power at the highest tillering stage were higher than those of the tillage rice. The average increase is about 40% and 14%; under...

Problems solved by technology

However, in terms of rice planting, in the environment of transplanting, plant protection, and harvesting, machinery frequently enters the field, resulting in uneven fields, which in turn affects rice no-tillage planting.
