Rotary tillage and ditching device

Abstract

The invention discloses a rotary tillage and ditching device. The rotary tillage and ditching device comprises a frame and a rotary tillage mechanism arranged on the frame. A forward plough used for opening up a trench is arranged ahead of a heading direction of the rotary tillage mechanism on the frame. A rotary tillage shaft of the rotary tillage mechanism is provided with two packing auger shaping mechanisms located behind the forward plough. All the packing auger shaping mechanisms are provided with auger blades spirally rotating around the rotary tillage shaft. The packing auger blades of the two packing auger shaping mechanisms are opposite in spiral directions and push top soil subjected to soil-turning operation by the forward plough to two sides of the opened trench when performing rotary motion along with the rotary tillage shaft. The rotary tillage and ditching device is advantaged by being simple and reasonable in structure, low in manufacture cost, small in resistance of trench digging, fine in trench digging quality and low in power consumption.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rotary tillage ditching device. Background technique [0002] There is a lot of rain in the southern part of our country. When planting, it is generally necessary to open a box ditch every few rows for drainage or for irrigation in case of drought. There are two main methods of mechanical ditch opening. One is to open the ditch first and then sow. This method uses different machines to complete the ditch opening and sowing operations successively, which is time-consuming and labor-intensive, and causes repeated pressure on the ground by the machine. It is solid, and the original ditch pattern may be destroyed during sowing; the other is to use a combined operation seeder to complete the opening of the ditch while sowing. At present, there are two main ways to open the ditch with the national ditching machine. One is to break the soil with a rotary tiller, and th...

Problems solved by technology

There are two main methods of mechanical ditch opening. One is to open the ditch first and then sow. This method uses different machines to complete the ditch opening and sowing operations successively, which is time-consuming and labor-intensive, and causes repeated pressure on the ground by the machine. solid, and the original ditch may be destroyed during sowing; the other is to use a combined operation seeder to complete the opening of the ditch at the same time as the sowing operation

At present, there are two main ways to open the ditch with the national ditching machine. One is to break the soil with a rotary tiller, and then use the rotary tiller to clear the complete ditch with the soil clearing shovel. This method is used to open the ditch. The ditch type is relatively neat, but the structure of the rotary tillage cutter head is complicated, it is inconvenient to install and disassemble, and it is not suitable for ditching in high-humidity fields

The other is to rely on the traction force of the tractor and use two-sided plows to open the ditch. The structure of the whole machine using this method is simple and light in weight, but the ditch shape is not neat enough, and the ditching resistance is relatively large, and the power consumption is high.
