Description
Technical Field
The invention belongs to the technical field of agricultural soil preparation machines and tools, and particularly relates to a rotary loosening integrated tillage machine and tool.
Background
At present, shallow rotary tillage is the most used tillage technology in the process of agricultural land preparation, but long-term rotary tillage causes the thickness of a soil plough layer to be thinner and a plough bottom layer to move upwards, so that the root growth of crops and the utilization of nutrient and moisture resources are limited. For this reason, deep scarification cultivation techniques have been proposed and popularized. The deep scarification cultivation can break the plough bottom layer, improve the soil moisture infiltration rate, enlarge the soil moisture storage capacity and promote the root system of the crops to be pricked down, thereby improving the crop yield. However, the deep scarification operation has large resistance, so that the energy consumption of the deep scarification operation is 2-4 times higher than that of a common harvesting machine; meanwhile, after single subsoiling operation, the ground is uneven, the soil ridges, the soil ditches and the soil blocks are large, tillage and soil preparation are usually completed by subsoiling and rotary tillage twice, and time and energy are consumed.
Chinese patent application publication No. CN 108668612 a discloses a stubble-cleaning, subsoiling, fertilizing and tilling combined machine, which comprises a frame, wherein a central reversing reduction gear box is arranged on the frame, a stubble-cleaning device is arranged below the front of the frame, a rotary tillage device is arranged on the frame at the rear of the stubble-cleaning device, a subsoiling shovel is arranged on the frame between the stubble-cleaning device and the rotary tillage device, a fertilizing mechanism is arranged above the frame, and a compacting and depth-limiting roller is hinged at the rear of the frame; the central reversing reduction gear box is provided with two-stage output shafts of an upper output shaft and a lower output shaft, the upper output shaft is linked with the stubble cleaning device through the side transmission gear box, the lower output shaft is linked with the rotary tillage device, and the pressing depth-limiting roller is linked with the fertilizing mechanism. The invention integrates the operation procedures of stubble cleaning, deep scarification, rotary tillage, fertilization, soil suppression and the like into a whole, has high production efficiency, is suitable for carrying out compound operation on the soil with the stubble left before sowing, and avoids the rolling of the tractor on the field soil caused by multiple ground feeding operations of the machine. However, the total energy required by the design of the deep scarification before rotary tillage and after rotary tillage is the sum of the rotary tillage and the deep scarification, and the energy consumption is large; the adopted common deep scarification plough has relatively low scarification degree and relatively poor soil crushing quality; the stubble cleaning device is limited by other parts and can only clean stubble once, the crushing quality of stubble straw is poor, the machine is easy to block in the using process, an ideal seeding state is difficult to achieve (the conventional operation is stubble cleaning for 2 times), and the seed germination rate is reduced due to the fact that too large straw is returned to the field.
