Both-side driven rotary tillage soil-working machine

Abstract

Two-side-driven rotary tillage soil-preparing machine, comprising transmission assembly and knife roller assembly, wherein the transmission assembly comprises an intermediate transmission box and left and right two side transmission boxes. A power input shaft and a differential connected to rear power output of the tractor through cardan joint are fixed in the intermediate transmission box, wherein a transmission gear is fixed on casing of differential and an input bevel pinion is mounted on the power input shaft, and the transmission gear and the bevel pinion transmit through gears. The differential has a structure that four orthogonal angle gears are fixed in the casing, wherein each of the two angle gears at left and right is connected with an output half shaft respectively of which outer end is connected to a drive gear in each of the two side transmission boxes respectively. When tooth spaces of gears in the left and right two side transmission boxes are not on a same line, the two angle gears at left and right in the differential would be lightly turned under the action of torque to make the drive gears in the two side transmission boxes normally work, thereby making knife roller assembly normally rotate. The soil-preparing machine has the advantages of gravity balance in whole body, fine stability and flat ground surface after ploughing.

Description

Technical field [0001] The invention relates to a rotary tillage machine, in particular to a two-side transmission rotary tillage soil preparation machine integrating rotary tillage, stubble burying and harrowing. Background technique [0002] Land preparation with rotary tillage machinery is a mature technology, and it is also a machine commonly used in rural areas across the country. The machine is mainly divided into two categories: the middle box transmission knife roller and the side box transmission knife roller. The characteristic of the middle transmission is that the rotary tiller rollers are on both sides of the middle transmission box. In order to avoid the leakage of the lower part of the middle box, a small plowshare is specially installed. The small plowshare can only cultivate the land statically and has poor soil turning ability. It is easy to cause clogging and omission of soil under the middle box. The side transmission is driven by a transmission box arranged o...

Problems solved by technology

Its biggest advantage is that there is no soil and missing tillage in the middle of the cutter roller, and the flatness of the land preparation is also good. The disadvantage is that the end of the cutter roller with the side box is heavy, and the end with the side plate is light, and the weight of the whole machine is unbalanced. It is inclined, so the ground plane is inclined after rotary tillage; since the power to drive the cutter roller is completed by one side box, the design strength of the single side side box must meet the needs of the total load, and the gear modulus is large , and the large modulus gear has poor bonding performance, resulting in large noise, high impact force, high oil temperature, and easy damage to parts; unilateral drive increases the torque at the side plate end of the cutter roller, and the cutter roller is easy to bend and break
