Rotary tiller shaft assembly for paddy field ridge building machine

Abstract

The rotary tiller shaft assembly for paddy field ridge building machine belongs to agricultural machinery; A knife seat, B knife seat, combined soil throwing knife seat and roller frame are fixed in sequence on the knife shaft, and the A, B knife seats and soil throwing The soil collecting knife A, the soil collecting knife B and the combined soil throwing knife are respectively fixed on the combined knife seat. Ф 2 Rotation diameter Ф of combined knife with throwing soil 1 , Rotation diameter Ф of soil collecting knife A 3 The size relationship is: Ф 2 >Ф 1 >Ф 3 , the turning diameter Ф of soil collecting knife B 2 It is less than or equal to the outer diameter Ф of the roller frame, and N pieces of shaping and compacting shrapnel are equipped on the outer surface of the roller; the assembly is novel and reasonable in structure, reliable in use, good in operation performance, and high in quality for building ridges.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a rotary tiller assembly used on a paddy field single-side ridge building machine. Background technique [0002] Paddy field single-side ridge building machines generally build new ridges through rotary tillage and suppression on the basis of old stalks, but the ridge-building rotary knife assembly currently developed only plays the role of crushing and collecting soil. The field ridge strength is low, the soil compactness in the field ridge is not high, and it is in a soft state, which is not only prone to water leakage, but also causes water loss in the paddy field, and is especially prone to ridge collapse and water leakage. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and combine the actual needs of paddy field production operations to design a rotary tiller shaft assembly for paddy f...

[0002] Paddy field single-side ridge building machines generally build new ridges through rotary tillage and suppression on the basis of old stalks, but the ridge-building rotary knife assembly currently developed only plays the role of crushing and collecting soil. The field ridge strength is low, and the soil compactness in the field ridge is not high, and it is in a soft state. Not only is it prone to water leakage, it will cause water loss in the paddy field, and it is especially prone to ridge collapse and water leakage.
