The Z-axis module comprises a gantry type frame and a Z-axis lifting mechanism. The Z-axis lifting mechanism comprises a Z-axis motor and a lead screw, wherein the Z-axis motor and the lead screw are mounted in the center position of the gantry type frame. The X-axis module is mounted on the gantry type frame of the Z-axis module. The lead screw is connected to the middle of the X-axis module to drive the X-axis module to ascend or descend on the gantry type frame. An extrusion machine capable of moving along the X axis is mounted on the X-axis module. The Y-axis module is arranged at the bottom of the gantry type frame. A working platform is arranged on the Y-axis module. The gantry type frame is in sliding fit with the Y-axis module. The 3D printer acts on the middle of the X-axis module through the single lead screw in the Z-axis direction, the mechanism is simplified, the stress of the lead screw is uniform, and meanwhile the gantry type printer structure is simple, stable to operate and capable of guaranteeing precise printing of a model.

The invention discloses an automatic leveling structure which aims at being capable of providing position compensation and automatic leveling functions and enabling a working assembly to automatically reach a level condition. The automatic leveling structure comprises an outer compensation seat, an inner compensation seat, an outer compensation shaft and an outer compensation column. The inner compensation seat is provided with a main inner seat bearing hole and an auxiliary inner seat bearing hole, a main front-back adjusting bearing is arranged in the main inner seat bearing hole, and an auxiliary front-back adjusting bearing is arranged in the auxiliary inner seat bearing hole. The outer compensation shaft and the main front-back adjusting bearing are connected, and the outer compensation column is connected with the auxiliary front-back adjusting bearing. The inner compensation seat is provided with a pendulum bob hole and an inner compensation shaft, a pendulum bob is arranged in the pendulum bob hole, and the inner compensation shaft is provided with two left-right adjusting bearings which are located in the corresponding pendulum bob bearing holes. The automatic leveling structure has the beneficial effects that the automatic leveling function is achieved, the capability of self-adaptive adjusting and buffering damping is achieved, flexibility and stability can be adjusted, and the automatic leveling structure meets various demands.

The invention provides a washing machine foot with an automatic leveling function and a washing machine. The washing machine foot includes: a sheath; an adjustment foot arranged in the sheath and capable of moving axially relative to it; and a flexible body assembly arranged in the adjustment foot It is used to accommodate hydraulic medium; one end of the flexible body component is limitedly installed in the sheath, and the other end is a telescopic end acting on the adjustment foot; the telescopic end stretches under the action of the hydraulic medium to drive the adjustment foot to the axial direction The movement realizes automatic leveling; the flexible body component includes a flexible containing body, an installation component for installing the flexible containing body, and a protection mechanism arranged between the mounting component and the flexible containing body for protecting the flexible containing body. In the present invention, the flexible body component is installed in the sheath in a limited position to avoid damage to the flexible body component. In addition, through the setting of the protection mechanism, the flexible containing body is prevented from directly contacting the installation component, which greatly reduces the damage probability of the flexible containing body and prolongs its life. service life.

The invention discloses a land leveling system for a paddy field rotary cultivator. The land leveling system comprises a left-side pull rod, a middle pull rod, a right-side pull rod, a land leveling unit, a driving unit, a hydraulic operation mechanism and a controller, wherein the hydraulic operation mechanism is used for manipulating the land leveling unit; the controller is used for controlling the hydraulic operation mechanism. The land leveling system for the paddy field rotary cultivator has the advantages that a land leveling device with an automatic leveling function is additionally arranged on a rotary cultivator according to agronomic requirements of rice cultivation, so that a land leveling plate is positioned in a horizontal plane all the time in the cultivating and land-leveling processes, therefore the influence to the land leveling device from a tractor due to different mud foot depths and own vibration during a proceeding process is reduced, and the land leveling precision is further improved. The land leveling system for the paddy field rotary cultivator can be used with the existing paddy field rotary cultivator for performing rotary cultivation and soil preparation on paddy fields in a matching manner, so that the land leveling effect of the paddy field rotary cultivator is improved; meanwhile in comparison with a paddy field laser land leveler, the land leveling system for the paddy field rotary cultivator has the advantages of low cost and convenience in popularization and application.

The invention provides a washing machine foot with an automatic leveling function and a washing machine. The washing machine foot includes: a sheath; an adjustment foot arranged in the sheath and capable of moving axially relative to it; and a flexible body assembly arranged in the adjustment foot Used to accommodate the hydraulic medium; one end of the flexible body assembly is limitedly installed in the sheath, and the other end is a telescopic end acting on the adjustment foot; the telescopic end of the flexible body assembly stretches and drives under the action of the hydraulic medium Adjustment feet move axially for self-leveling. According to the principle of hydraulic pressure, the feet of the washing machine of the present invention are filled with hydraulic media in the feet. For different pressures, due to the fluidity of the hydraulic media, the feet are automatically adjusted adaptively, and the hydraulic media is placed in a sealed container. In the flexible body assembly, the flexible containing body is placed inside the adjustment foot, which effectively solves the problem of hydraulic medium leakage and ensures the stability of the foot work.
