The invention belongs to the technical field of agricultural water and fertilizer machines, and particularly relates to a movable water and fertilizer all-in-one machine which comprises an agricultural water and fertilizer machine assembly and a moving mechanism, the moving mechanism comprises a base and four driving shafts, the four driving shafts are connected to the front side and the rear side of the base through shafts, and driving wheels are integrally formed at the outer ends of the driving shafts; the agricultural water and fertilizer machine assembly is fixedly installed above the base through bolts, cams and a plurality of ground gripping shafts are arranged in the four driving wheels, a plurality of sliding grooves are evenly formed in the driving wheels, the ground gripping shafts are slidably connected into the sliding grooves, the cams are arranged in the middles of the driving wheels, and the ground gripping shafts are arranged in the sliding grooves. A counter bore is formed in the driving shaft, a shaft rod is slidably connected into the counter bore, a limiting part is arranged at the sliding connection position, and one end of the shaft rod and the cam are integrally formed. The outer end of the ground gripping shaft is sharp, the inner end of the ground gripping shaft is arc-shaped, and the device solves the problems that an existing agricultural water and fertilizer machine is difficult to move and low in efficiency in actual farmland application.

This application relates to the field of hot molding processing technology, specifically a hot molding pre-assembly fixture and a hot molding pre-forming method. The hot molding pre-assembly fixture includes a central mold and side molds; a first anti-slip portion is provided on the first clamping surface of the central mold to increase the frictional force on the material layer in the web region; a second anti-slip portion is provided on the second clamping surface of the side molds to increase the frictional force on the material layer in the flange region; and the groove depth of the first anti-slip portion is greater than the groove depth of the second anti-slip portion. In this embodiment of the hot molding pre-assembly fixture, the first anti-slip portion can apply an effective dragging force to the material layer in the web region, causing the material layer to follow the mold movement and fully extend. The second anti-slip portion allows for a differentiated matching relationship between the frictional resistance of the side mold to the material layer in the flange region and the frictional driving force of the central mold to the material layer in the web region. This depth difference helps to limit unintended slippage of the material layer in the flange region during the molding process.

The invention relates to the technical field of medical instruments, in particular to a bronchial sputum plug cleaning device which comprises a catheter and a guide wire movably arranged in the catheter and further comprises a cleaning part arranged at the end of the guide wire and capable of being connected with a sputum plug through pulling and winding and moving out of the catheter along with the guide wire; the control part is arranged on the outer side of the tail end of the guide wire and can control the guide wire to be pulled and rotated, according to the bronchial sputum embolism cleaning device, the conical spiral winding wire is designed to serve as the cleaning part and can be flexibly bent in the bronchial tube and effectively make contact with the sputum embolism, and the outermost ring of the large end of the winding wire is a smooth section; the sputum suppository is simple in structure and convenient to use, damage to the bronchus wall when the sputum suppository passes through the bronchus is avoided, operation safety is guaranteed, meanwhile, the sputum suppository grabbing effect is enhanced through the cilia design on the winding wire, and the sputum suppository can be wound more effectively and moved out of the catheter along with the guide wire.

The invention discloses a robot gripper, and relates to the technical field of robot devices, the robot gripper mainly comprises a gripper main body and filling pieces, a plurality of grooves are formed in the non-gripping surface of the gripper main body in the length direction, the filling pieces are arranged in the grooves, and the gripper main body is connected with a first driving device; the first driving device can drive the gripper body to grab or put down an object, the filling piece is connected with a second driving device, and the second driving device can enable the value of pressure applied by the filling piece to the gripper body to change. The invention further discloses a robot which comprises the robot gripper. The high reliability of object grabbing can be guaranteed, and the grabbing precision can be improved.
