The utility model relates to the technical field of reinforcing steel bar planting equipment, and discloses a reinforcing steel bar planting device which comprises a connecting cylinder, the top of the connecting cylinder is fixedly connected with a handle, the inner wall of the connecting cylinder is fixedly connected with a mounting block, the top of the mounting block is provided with an air pump, the air inlet end of the air pump penetrates out of the mounting block, and the air inlet end of the air pump is connected with the handle. A detachable cover plate is arranged on the surface of the connecting cylinder; the cleaning module is arranged on the surface of the connecting cylinder, and the cleaning module is used for cleaning the steel bar planting holes; by arranging the collecting assembly, the air pump and the connecting cylinder, external air can be guided into the planting holes under the action of the air pump, dust disintegrating slag is carried into the connecting cylinder, and in the process, the dust disintegrating slag can be collected into the connecting cylinder under the action of the collecting assembly; and dust and disintegrating slag are prevented from falling back into the hole under the influence of gravity in the extraction process, the cleaning effect is improved, and dust raising pollution caused by a traditional hole washing mode is avoided through the mode.

The invention relates to the technical field of textile transportation equipment, and discloses a conveying trolley which comprises a moving assembly, an overturning assembly, a clamping assembly, an adjusting assembly and a push rod assembly, the overturning assembly and the clamping assembly are both arranged above the moving assembly, and the adjusting assembly is arranged above the clamping assembly. The push rod assembly is arranged on one side of the moving assembly, the moving assembly is arranged to control the trolley to move, so that the trolley runs according to set stations and set actions, cloth rolls are conveniently and rapidly unloaded by controlling the overturning angle of the overturning assembly, and paper tubes of different specifications are conveniently fixed through mutual cooperation of the clamping assembly and the adjusting assembly; through the push rod assembly, the air swelling shaft can be conveniently and rapidly pushed into a station, through mutual cooperation of the moving assembly, the overturning assembly, the clamping assembly, the adjusting assembly and the push rod assembly, the processes of coil unloading, transportation and shaft replacement are accurately and automatically completed, manual intervention is avoided, and the production efficiency is improved.

The invention relates to the technical field of plate machining drilling machines, in particular to a plate machining drilling machine with a tool protection function. According to the plate machining drilling machine with the tool protection function, scrap iron can be adsorbed and collected, and the scrap iron is prevented from being attached to a tool and damaging the tool. A plate machining drilling machine with a cutter protection function comprises a machining drilling machine body, a moving frame, a drill bit and a protection mechanism, the moving frame is arranged on the upper portion of the machining drilling machine body, the drill bit is arranged on the moving frame, and the protection mechanism capable of protecting the drill bit is arranged on the moving frame. According to the scrap iron collecting device, adsorption plates are far away from each other, a telescopic swing rod rotates, a sliding block is pulled to move upwards, the sliding block pushes scrap iron adsorbed to the adsorption plates to a collecting groove, the scrap iron enters a collecting frame, and the effects that the scrap iron can be adsorbed and collected, and the scrap iron is prevented from being attached to a tool and damaging the tool are achieved.

This utility model discloses a casing for a potted motor to prevent coil detachment. It includes a casing body and first limiting ribs. The first limiting ribs are spaced apart on the inner wall of the casing body, extending axially along the length of the casing body. A glue-holding groove is recessed on each first limiting rib, and a stop is provided at one end of the first limiting rib away from the rear of the casing body. The potted motor casing of this utility model, which prevents coil detachment, uses the stop to limit the forward movement of the stator. When potting the stator windings with potting compound, some of the compound is squeezed into the glue-holding groove. The integral molding of the potting compound on the stator windings and the compound in the glue-holding groove improves the stability of the stator, preventing the stator windings from retracting due to external impacts and effectively preventing coil detachment.
