A flatting and puddling paddy field machine through shaft type cutter shaft roller with cage-type cutter rests and toothed cutters

Abstract

The invention discloses a through-shaft cage-type knife holder toothed cutter shaft roller for a paddy field level paddy mixer, which is composed of a cutter shaft tube and an array of knife rack mechanisms. Adjacent two groups of knife rest mechanisms are arranged in a staggered manner; when working, the power is transmitted to the knife shaft tube, and the knife shaft tube drives the array of knife rest mechanisms to rotate around the central axis of the knife shaft tube at high speed. The remaining crop roots, stems, and leaves are cut at high speed, so that the soil is finely crushed and fully mixed with the chopped crop residual organic debris to achieve the effect of loosening the soil and enhancing soil fertility. Work in the field soaked in water for more than 48 hours The effect is better. The invention has the advantages of simple structure, good overall toughness, high strength, and wear resistance. It adopts the principle of cutting and pulverizing soil and does not need to replace the toothed blade. High efficiency, low maintenance cost.

Description

technical field [0001] The patent of the present invention relates to an agricultural tool, in particular to a through-shaft cage-type knife holder toothed knife shaft roller for a paddy field flat ground mixer. technical background [0002] Most of the existing paddy field level ground mixers are cutter shafts welded to the knife magazine, and the blades are connected by bolts and fixed on the knife magazine. When hard foreign objects such as bricks, stones, and tiles are encountered, the blades are easily broken; when the rice harvester is harvesting high stubble land, the knife shaft stick is easy to entangle the grass, which seriously affects the operation effect; represented by "Jiangsu Lianyungang area" The "Southern series" paddy field leveling paddy mixer has the same overall structure and transmission layout as the rotary tiller for dry fields. It is an overall large frame. The defect to be avoided is that the space occupied by the intermediate transmission part wi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the blades are easy to loosen, lose, and break when the above-mentioned existing paddy field flat ground mixer is working, the operation is missed, the cutter shaft roller is entangled in the operation of the high stubble field, and the operation efficiency is low and the fuel consumption is low. Due to the problem of insufficient rigidity of the cutter shaft roller of the large-scale model with a working width of more than 3.0 meters, a penetrating shaft cage type knife holder toothed cutter shaft roller for a paddy field flat ground mixer is proposed.
