Abstract

The invention discloses a paddy field leveling device with a spherical hinge connecting and hydraulic cylinder forming link mechanism. The device can achieve four-freedom moving of a scraper, namely scraper lifting, scraper swinging, scraper horizontal swinging and scraper angle converting, and scraper leveling various tasks are completed. The device comprises a connecting plate, a machine frame, a swinging frame, a Y-shaped base, a scraper left-right lifting hydraulic cylinder, a swinging hydraulic cylinder, a dragging frame, an angle converting hydraulic cylinder and a spherical hinge mechanism. A spherical hinge is arranged at the front end of the dragging frame. The spherical hinge and a ball face bearing base on the connecting plate form a spherical hinge mechanism, and spherical hinge type connecting of the dragging frame is formed. The machine frame is welded with the connecting plate and the swinging frame, and the Y-shaped base is hinged to the swinging frame. Ear shafts of the scraper left-right lifting hydraulic cylinder and the swinging hydraulic cylinder are hinged to the Y-shaped base. A piston rod ear ring is connected with the spherical hinge on the dragging frame, and the space link mechanism is formed with the dragging frame. An external hydraulic power source drives and controls the hydraulic cylinders to move. A scraper angle converting hydraulic cylinder tail ear ring is hinged to two side wing plates on the dragging frame, and an ear ring at the other end is hinged to an angle position machine. The back of the scraper is welded with a supporting plate. The scraper angel position machine is fixed on the supporting plate.

Description

technical field [0001] The invention relates to an agricultural paddy field leveling machine tool, in particular to a paddy field leveling device with a connecting rod mechanism composed of a ball joint connection and a hydraulic cylinder. Background technique [0002] The surface level of farmland has an important impact on the quality and efficiency of irrigation. After the land is leveled, crop yields can be increased by 20% to 30%, water can be saved by 30% to 50%, the land utilization rate of paddy fields is greatly improved, and pesticides, fertilizers and The amount of herbicide used. The working efficiency and precision of paddy field graders greatly affect the yield of crops. [0003] Rice production has high requirements on paddy field leveling. In order to ensure that the paddy field is moist and there is basically no water layer during rice planting, the paddy field must be leveled to facilitate uniform irrigation after planting and not cause seedling flooding....
