Intermediate driven small-angle oblique deep rotary tilling device

Abstract

The invention discloses an intermediate driven small-angle oblique deep rotary tilling device. The device comprises a rack, a suspension part, a gearbox and knife rolls, wherein the gearbox is positioned at the center of the rack; the output shaft of the gearbox is a spline shaft, and two sides of the output shaft are respectively connected with on end of the knife rolls on two sides of the output shaft; the other end of each knife roll is arranged in the bearing of a bearing block, and the bearing block is fixed inside the rack through screws; each knife roll comprises a rotary tilling blade, a blade disk and a blade shaft; the knife rolls are obliquely arranged in a plane, and form a theta-degree angle with a driving shaft of a truck tractor. According to the intermediate driven small-angle oblique deep rotary tilling device, soil under the gearbox can be removed, the gearbox is prevented from interfering with untilled land during working, lateral force is greatly reduced, high-reliability deep tillage and excellent grass-burying and stubble-cleaning capability can be achieved. The intermediate driven small-angle oblique deep rotary tilling device is applied to the technical field agricultural machinery.

Description

technical field [0001] The invention belongs to the field of agricultural engineering research, and in particular relates to a small-angle inclined deep rotary tiller with intermediate transmission. Background technique [0002] In recent years, with the support of the country's policy of vigorously promoting agricultural mechanization, large-scale agricultural machinery has developed rapidly, especially in southern my country. The demand for rotary tillers has soared, and there are also updated requirements for the functions of rotary tillers. my country's agricultural machinery manufacturing industry has developed and produced many types of rotary tillers. However, all rotary tillers currently on the market, no matter whether they are unilaterally driven and single-shaft type or intermediately driven with split shafts on both sides, the soil under the intermediate transmission box is difficult to remove during deep rotary tillage, thus affecting the tillage depth and tilla...

AI Technical Summary

Problems solved by technology

However, all rotary tillers currently on the market, no matter whether they are unilateral drive single shaft type or intermediate drive two-side split shaft type, the soil under the intermediate transmission box is difficult to remove during deep rotary tillage, which affects the tillage depth and tillage quality.

In the prior art, the general solution to the middle box of the intermediate transmission rotary tiller, missing tillage, and missing stubble is to install a plow shovel at the bottom of the box to plow the missing tillage under the box, so that the cultivation quality of the lower part of the middle box can be improved. The crushing quality requirements cannot be met, especially for the stubble removal machine driven in the middle, the effect of stubble removal in the middle area is extremely poor, and a large number of stubbles are left in the field, which greatly affects the quality and effect of cultivation

There are currently no fully adapted and up-to-standard deep rotary tillers in the market. These rotary tillers generally have fatal defects such as high manufacturing costs, short service life, easy damage, and low reliability.
