This utility model relates to the technical field of drip irrigation devices, specifically to a drip irrigation device for high-yield wheat cultivation. It includes an external pipe and a main pipe. A filter section is located at one end of the main pipe, within the external pipe. Equally spaced pipe assemblies and an external filter pipe are fixedly connected to the outside of the main pipe. A delivery branch pipe connects the external filter pipe and the main pipe. A filter screen is fitted onto the surface of the filter section. An extension section and a flow guide section are located at the connection point between the external pipe and the main pipe. Through holes are formed on the surface of the filter section. The external pipe facilitates threaded connection between the entire device and external liquid supply equipment. The flow guide section concentrates and directs the input external liquid. The extension section ensures proper flow of the liquid through the through holes. The filter screen filters the input external liquid. The through holes facilitate the entry of the filtered external liquid into the main pipe.

The utility model discloses a dismounting tool for a moving side assembly of a GIS breaker arc extinguish chamber, comprising an operation board, a fixed support and a plurality of positioning pins, the operation board comprises an axial through center hole, the plurality of positioning pins are fixed on the top surface of the operation board and are uniformly distributed along the circumferential direction of the operation board; the top end of the fixing support is connected with the bottom face of the operation board. The fixing support of the disassembling and assembling jig is fixed on the workbench, the operation board is in a horizontal state, and the receiving disc of the movable side assembly is placed on the top face of the operation board. And after being circumferentially positioned by the positioning pin on the top surface of the operating panel, the connecting hole on the connecting disc can be conveniently in threaded connection with a connecting rod or a contact seat, and a rated torque is achieved.

The application discloses a garden shovel for garden engineering, and relates to the technical field of garden maintenance, which comprises a shovel handle, a shovel head arranged on the shovel handle, an extension handle arranged at one end of the shovel handle away from the shovel head, a threaded end arranged at one end of the shovel handle away from the shovel head, a threaded hole arranged at one end of the extension handle close to the shovel handle and threadedly connected with the threaded end, a fixing sleeve arranged on the shovel handle, the end of the shovel handle connected with the extension handle being sleeved in the fixing sleeve, the side walls of the shovel handle and the extension handle being attached to the inner side wall of the fixing sleeve, a blocking plate arranged on the shovel handle and attached to the fixing sleeve, and a fixing plate arranged at one end of the extension handle close to the shovel handle and attached to the fixing sleeve. The cooperation relationship between the threaded end and the threaded hole is controlled, the connection relationship between the shovel handle and the extension handle is changed, and the type of the garden shovel is adjusted, so that different types of garden shovels are directly replaced, and the problem of inconvenience in carrying multiple garden shovels is solved.

The utility model relates to the technical field of motor end covers, in particular to a vibration reduction end cover of a motor, which comprises a motor shell, a motor rotor is arranged on the surface of the motor shell, an end cover body is fixedly mounted on the surface of the motor shell, and a fixing seat is fixedly connected onto the surface of the motor shell. A movable plate is rotationally connected to the surface of the fixed seat, a limiting plate is fixedly connected to the surface of the movable plate, and a fixed plate is fixedly connected to the surface of the end cover body. The movable plate is rotated on the fixed seat, so that the limiting plate is clamped and connected to the clamping groove of the fixed plate, and then the first bolt penetrates through the circular hole of the fixed plate, so that the first bolt is in threaded connection to the threaded groove of the limiting plate; the movable plate and the limiting plate limit the position of the end cover body on the motor shell through the fixed plate, so that the phenomenon that the end cover body vibrates on the motor shell is avoided, and noise is avoided.
