Paddy field soil turning and soil preparing integrated machine applicable to minimal tillage planting mode

Abstract

The invention provides a paddy field soil turning and soil preparing integrated machine applicable to a minimal tillage planting mode, and belongs to the technical field of rice farming machinery. Thesoil turning and soil preparing integrated machine comprises a frame, steering wheels, traveling wheels, a power source and tilling units, the steering wheels arranged at the front end of the frame,the traveling wheels and the power source are arranged at the rear end of the frame, the power source drives the traveling wheels to rotate, the tilling units are positioned on the frame among the steering wheels and the traveling wheels at intervals and comprise enclosed covers, tillage cutters and dispersion shafts, the enclosed covers are fixed on the frame, the tillage cutters are fixed into the enclosed covers and extend out of the front ends of the enclosed covers, a plurality of dispersion cutter heads are fixedly arranged at the front ends of the dispersion shafts, a fixed connecting rod, a movable connecting rod, a swinging arm and a second connecting plate are hinged in an end-to-end manner to form a connecting rod mechanism, an input shaft is connected at the rear end of each dispersion shaft through a universal joint, and the input shafts are connected with the power source. The integrated machine has the advantages that the machine is high in efficiency and applicable to the minimal tillage planting mode.

Description

technical field [0001] The invention belongs to the technical field of rice agricultural machinery, and relates to an all-in-one machine for turning and preparing soil in a rice field suitable for a low-tillage planting mode. Background technique [0002] The less-tillage planting mode of rice generally refers to the rice protective less-tillage and water-saving technology developed by the Harbin Agricultural Machinery Research Institute in the industry. This technology refers to the soil between two rows of rice stubble in the harvested rice field. The soil between the rice stubbles is rotary tilled in a strip shape and the soil is prepared, the original rice stubbles are kept, and the seedlings are inserted between the two rice stubbles after the soil has been turned and prepared. The advantage of doing this is that it can reduce 50% of the soil plowing; greatly reduce the power consumption and cost of paddy field operation; due to the adoption of the strip-shaped method o...

Problems solved by technology

[0003] Although the above-mentioned less-tillage planting mode has many advantages, its advantages are all based on its ideal cultivation method and ideal planting method. From the aspect of land preparation, it is difficult for the traditional rotary tiller to ensure the soil in the plowed sheet area. It is broken up at one time, and the rotary tiller is easy to squeeze the soil in the plowed area into the unplowed area where the rice stubble is located, making the leveling process very laborious due to the existence of the rice stubble

[0004] Based on this, under the low-tillage planting mode, the plowing and whole-field equipment needs to have the following functions: 1. Ensure that the soil turned up in the patchy plowed area does not enter the unplowed part where the rice stubble is; The piece of soil needs to be scattered and crushed in the plowing area, and it should be kept in the original position as much as possible; 3. The plowing and soil consolidation process should be completed at one time, because the plowing area is limited to adjacent rice stubbles. It is very difficult for the agricultural machine to keep the same trajectory as the first plowing track during the second plowing or soil preparation, making it difficult to achieve the goal of reducing the plowed soil by 50%; 4. Traditional scattered broken soil The tooth-shaped structure scraping method is adopted. Due to the influence of soil resistance, the loose soil structure cannot be fixed in the longitudinal position, resulting in uneven scattered soil, which requires multiple operations to achieve uniformity. This is also an important factor affecting the one-time completion of soil plowing. factor
