Example Embodiment

[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0024] A leveling shovel height adjustment mechanism of a paddy field laser grader includes a leveling blade, a leveling shovel rotating frame, a suspension mounting frame, a synchronous parallel rod, a synchronous motion frame, an elevation cylinder bracket, an elevation cylinder and a receiver mounting rod. The suspension mounting frame, the shovel rotating frame, the synchronous motion frame and the synchronous parallel rod constitute a parallelogram mechanism.

[0025] The front and rear ends of the suspension mounting frame are arranged along the vertical direction. The front face is provided with a three-point suspension interface, through which the shovel height adjustment mechanism of the paddy field laser grader is hooked on the tractor. On the rear end face, the upper end is hinged with the synchronous parallel rod, the middle part is fixedl...

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...
