Paddy-field grass-burying roller

Abstract

The invention relates to a paddy-field grass-burying roller belonging to spare parts of agricultural machinery and aiming at the defects that the prior paddy-field grass-burying operation part is uniformly designed on a rotary blade, not only increases the resistance of the rotary blade and enables a tractor to work in an overload working state, but also influences the grass-burying operation effect and has the problem of often bringing up straw and weeds justly buried. The paddy-field grass-burying roller comprises two corresponding roller end boards, strip grass-burying boards and a roller shaft, wherein the strip grass-burying boards are sequentially connected between the two corresponding roller end boards and respectively have a backward angle, and the roller shaft is arranged in the center of the roller end boards. The invention has the following advantages after tests that the paddy-field grass-burying roller can not increase the resistance of the rotary blade so as not to influence the normal operation of the tractor, not only can press crop straw and weeds into paddy-field mud, but also adds the functions of puddling and leveling a paddy field by crushed clods, is suitable for matching with tractors of various models and can be towed by animal labor or connected with a dry-field operation compression roller for the paddy-field grass-burying operation, thereby being a grass-burying operation part with good suitability, simple structure and low cost.

Description

Technical field: [0001] The invention belongs to parts and accessories of agricultural machinery, in particular to a paddy field grass-burying roller used for the grass-burying operation of a rotary tiller. Background technique: [0002] Chinese patent ZL200620076398.8 discloses a paddy field grass-burying rotary tillage composite cutter, which is composed of two grass-burying knives symmetrically welded at an angle of 92-102 degrees on both sides of the head of the rotary tiller; Chinese patent ZL200620076661.3 discloses A stubble-burying rotary tiller, the left and right of the grass-pressing parts respectively have four grass-pressing plates connected to the back of the rotary tiller through connecting pieces. What they have in common is that the grass-burying parts are designed on the rotary tiller. On the one hand, the load and resistance of the rotary tiller are increased. Not only must the shape of the rotary tiller be redesigned and its strength must be improved, oth...

AI Technical Summary

Problems solved by technology

What they have in common is that the grass-burying parts are designed on the rotary tiller. On the one hand, the load and resistance of the rotary tiller are increased. Not only must the shape of the rotary tiller be redesigned and its strength must be improved, otherwise the rotary tiller will be seriously affected. More seriously, the tractor engine that provides power to the rotary tiller is overwhelmed and is in an overloaded working state; The plowing operation is carried out at the same time, which not only affects the effect of the plowing operation, but also affects the effect of the burying operation, and it is often difficult to avoid bringing up the crop stalks that have just been buried.
