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

Embodiment Construction

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

[0024] A leveling blade height adjustment mechanism of a paddy field laser grader, comprising: a leveling blade, a leveling blade turret, a suspension installation frame, a synchronous parallel bar, a synchronous movement frame, an elevation oil cylinder bracket, an elevation oil cylinder, and a receiver installation rod. The suspension installation frame, the shovel turret, the synchronous movement frame and the synchronous parallel bar constitute a parallelogram mechanism.

[0025] The front and rear end surfaces of the suspension mounting frame are arranged along the vertical direction. There is a three-point suspension interface on the front end, through which the leveling blade elevation adjustment mechanism of the paddy field laser grader is hooked to the tractor. On the rear end face, the upper end is hinged with the synchronous par...

Abstract

The invention relates to a shovel elevation adjustment mechanism of a paddy field laser grader, comprising: a shovel blade, a shovel turret, a suspension mounting frame, a synchronous parallel bar, a synchronous movement frame, an elevation oil cylinder bracket, an elevation oil cylinder, and a receiver installation rod ;The leveling blade is fixed on the lower end of the leveling shovel turret, and the upper end of the leveling shovel turret is hinged to the lower end of the suspension mounting frame; The upper end of the oil cylinder is hinged, and the lower end of the elevation oil cylinder is hinged with the shovel turret; the suspension mounting frame, the shovel turret, the synchronous motion frame and the synchronous parallel rod form a parallelogram mechanism, and the receiver mounting rod is fixed on the synchronous motion frame. The invention has the advantages of simple structure, easy control, improved leveling precision and no influence on the center of gravity of the paddy field grader, and belongs to the technical field of agricultural paddy field tillage equipment.

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...
