Flat shovel height adjusting mechanism of paddy field laser land leveler

Abstract

The invention relates to a flat shovel height adjusting mechanism of a paddy field laser land leveler, and belongs to the technical field of agricultural paddy field tillage machines. The flat shovel height adjusting mechanism of the paddy field laser land leveler comprises a flat shovel blade, a flat shovel rotating frame, a suspension mounting frame, synchronous parallel rods, a synchronous motion frame, a height oil cylinder support, a height oil cylinder and a receiver installation rod. The flat shovel blade is fixed to the lower end of the flat shovel rotating frame. The upper end of the flat shovel rotating frame is hinged to the lower end of the suspension mounting frame. The height oil cylinder support is located above the flat shovel rotating frame, one end of the height oil cylinder support is fixedly connected with the suspension mounting frame, and the other end of the height oil cylinder support is hinged to the upper end of the height oil cylinder. The lower end of the height oil cylinder is hinged to the flat shovel rotating frame. The suspension mounting frame, the flat shovel rotating frame, the synchronous motion frame and the synchronous parallel rods form a parallelogram mechanism. The receiver installation rod is fixed to the synchronous motion frame. The flat shovel height adjusting mechanism of the paddy field laser land leveler has the advantages of being simple in structure and easy to control, improving the leveling precision, and not affecting the gravity center of the paddy field land leveler.

Description

technical field [0001] The invention relates to an agricultural paddy field plowing tool, in particular to a leveling blade elevation adjustment mechanism of a paddy field laser grader. Background technique [0002] Rice production has high requirements for paddy field leveling and irrigation and drainage. There is a folk proverb in our country that "an inch of water does not fill the field". In order to ensure that the paddy field is moist when the rice is planted and there is basically no water layer (direct seeding) or a thin water layer (transplanting), the paddy field must be leveled to facilitate even irrigation after sowing. without causing partial flooding. At the same time, the leveling of paddy fields is an important factor affecting rice production. The leveling of the field surface has a great impact on the water use efficiency and water distribution uniformity under surface irrigation conditions. Precisely leveling the land can improve the efficiency and unifor...

Problems solved by technology

The parallel link mechanism of these two methods of height adjustment of the shovel lengthens the distance between the shovel and the pulling tractor, which affects the center of gravity of the shovel. In addition, the self-weight of the shovel causes the shovel to rise and fall asymmetrically, and it is difficult for the laser controller to play its best role. excellent control performance
