Paddy field high-stubble double-shaft slurry-stirring stubble-burying grader

Abstract

The invention relates to a paddy field high-stubble double-shaft slurry-stirring stubble-burying grader, and belongs to agricultural machinery. The grader is composed of a cover plate, a beating bladeroller and a stubble-pressing blade roller, wherein the beating blade roller is composed by fixing beating curved blades to a beating blade shaft, the stubble-pressing blade roller is composed by fixing stubble-pressing spring teeth to a stubble-pressing shaft, the cover plate is formed by the parallel arrangement of a cover plate I and a cover plate II, two or more fixing plates I are fixedly arranged on the cover plate I at equal intervals, positions, corresponding to the fixing plates I, on the cover plate II are provided with fixing plates II, the end heads of the fixing plates I and thefixing plates II are movably connected, the upper end of the cover plate I is provided with a double-output shaft hydraulic motor I, lower end bearings of vertical plates I on two sides are equipped with the beating blade shaft, and gears at end heads of radial power output shafts I, and gears at two ends of the beating blade shaft are in transmission connection. The paddy field high-stubble double-shaft slurry-stirring stubble-burying grader adopts double-output shaft hydraulic motors as a power source of a beating apparatus and a stubble-pressing apparatus, and has high stubble-removal rateand good evenness after operation.

Description

technical field [0001] The invention belongs to agricultural machinery, and in particular relates to a paddy field high-stubble double-axis stirring stubble-burying grader. Background technique [0002] As an important link in rice production, paddy stirring and soil preparation before rice transplanting are of great significance to the transplanting quality of rice seedlings, field management, subsequent growth and yield of rice. Traditional paddy field preparation in spring in a rice-ripening area in the north includes plowing, rotary tillage, harrowing, and equalization. Generally, power-driven slurry operation is performed before transplanting rice seedlings. However, the amount of straw in the paddy area is large and the temperature is low, and the straw rots slowly. It is easy to float on the water surface or pile up on the ground after water is released and stirred in spring, which affects the normal operation of the rice transplanter.

Problems solved by technology

Traditional paddy field preparation in spring in a rice-ripening area in the north includes plowing, rotary tillage, harrowing, and equalization. Generally, power-driven slurry operation is performed before transplanting rice seedlings. However, the amount of straw in the paddy area is large and the temperature is low, and the straw rots slowly. It is easy to float on the water surface or pile up on the ground after water is put into the slurry in spring, which will affect the normal operation of the rice transplanter.

[0003] The power of the beating device and the stubble pressing device of the ordinary double-shaft beater currently used comes from the output power of the power output shaft of the tractor. The rotation speed of the stubble roller and the stubble roller is not constant, which is affected by the operating speed of the locomotive, resulting in a low stubble removal rate and poor flatness; in addition, the existing stubble cutter roller will work for a period of time when the stubble is pressed. The operation effect even leads to the locking of the cutter roller; at the same time, the paddy field mixer does not bury the stubble and straw well, and the floating straw needs to be manually fished out after the machine works, which delays farming time and increases labor costs
