This invention provides a self-feeding progressive brick-making device for construction waste, belonging to the field of brick making. It includes a lower frame, with an upper frame fixed above it. The lower frame holds a brick mold to be pressed, and the construction waste to be pressed is placed inside the brick mold. An upper mold, corresponding to the brick mold, is mounted above the brick mold and can press the material downwards. The upper frame is fitted with a lead screw that rotates up and down via a self-rotating axis through a vertical threaded hole. A ring-shaped cam is coaxially fixed to the lower part of the lead screw. Two or more ring-shaped, evenly distributed pressing heads are located below the cam. The upper part of each pressing head elastically presses against the pressing surface below the ring-shaped cam. This device continuously vibrates while pressing the construction waste inside the brick mold using the upper mold, ensuring uniform distribution of the waste material and improving the quality of bricks made from construction waste. Furthermore, the device has a simple and compact structure, significantly reducing the overall size of the device.

This invention discloses a winch transmission device with a quickly replaceable drum body, comprising a drum body, two connecting hubs at each end of the drum body, and a base on one side of the drum body; the two connecting hubs are connected to the base via two supports; and couplings and water / gas gauges are respectively provided at the ends of the two connecting hubs. Compared with the existing integral drum body assembly structure, the winch drum shaft assembly of this invention adopts a segmented structure, with the drum body connected to the two connecting hubs via pin assemblies and bolts; by removing all the pin assemblies and bolts on both sides of the drum body, the drum body can be quickly removed. The winch drum body assembly of this invention adopts a non-through-type drum shaft structure, which is simple to transmit and lightweight; moreover, the drum body replacement process is quick and convenient, saving time and effort, and is highly efficient.

The application discloses a kind of production device of recycled asphalt mixture and preparation method thereof, it is related to asphalt production equipment technical field, including mixing tank, feeding assembly, feeding port, storage tank and liquid conveying assembly;Mixing tank is equipped with stirring assembly with stirring shaft and spray pipe, and is equipped with discharge pipe at bottom;Feeding assembly includes conveying cylinder, screw conveying piece and reciprocating slideable sliding cylinder and feeding pipe;Feeding port is equipped with radially extending feed opening, and both sides inclined baffle strip forms gradually narrowing feeding opening from outside to inside.Working time, feeding pipe reciprocating sweep cooperation radial gradient feeding makes material feeding quantity and stirring intensity adaptation, solid-liquid component synchronous mixing.The application can avoid material accumulation in weak stirring zone, improve mixing uniformity and mixing efficiency, realize multi-component accurate proportioning and continuous production, improve the road performance of recycled asphalt mixture, and is suitable for efficient recycling of waste asphalt pavement material.

The utility model discloses a double-suction centrifugal fan which comprises a fan shell, a fan cover and a fan cover. An impeller; the outer rotor motor is arranged in the center area of the impeller in a penetrating mode, the outer rotor motor comprises an outer rotor and a stator winding, the stator winding is sleeved with the outer rotor, and the outer rotor is connected with the impeller; and the two current collectors are symmetrically arranged at the two axial end parts of the outer rotor motor, and the current collectors are connected with the connecting shaft of the stator winding. The outer rotor motor is connected with the impeller through the outer rotor to drive the impeller to rotate, and transmission between the outer rotor motor and the impeller is simple and efficient. The outer rotor motor is arranged in the center area of the impeller in a penetrating mode, the center area of the impeller is utilized, the outer rotor motor cannot affect air inlet of the two sides of the impeller, and therefore the air inlet amount of the two sides of the double-suction centrifugal fan is consistent, the structure is compact, and the overall size is small; furthermore, the flow collector not only plays a role in guiding inlet air of the impeller, but also plays a role in supporting the outer rotor motor.

A sheet metal processing device with adhesive attachments, belonging to the field of machining equipment technology, aims to solve the problems of excessive manual intervention, low positioning accuracy, and poor production efficiency in existing sheet metal and attachment bonding processes. The device includes a conveyor belt, on which a first robotic arm, a gluing device, a sensor, an L-shaped calibration block, a second robotic arm, and a top pressure plate are sequentially mounted. Sheet metal storage platforms, receiving platforms, and attachment storage platforms are respectively located at both ends and the sides of the conveyor belt. The robotic arm's execution terminal is a vacuum suction cup. Through the coordinated operation of these components, the device automates the processes of sheet metal feeding, gluing, positioning, attachment bonding, compaction, and receiving, improving processing accuracy and efficiency while preventing workpiece damage.

The folding chair comprises a backrest rod and a sliding armrest, the sliding armrest is provided with a cavity, a sliding seat and a hydraulic rod are arranged in the cavity of the sliding armrest, the first end of the hydraulic rod is connected with the sliding armrest, the second end of the hydraulic rod is connected with the sliding seat, and the hydraulic rod drives the sliding armrest to move relative to the sliding seat when stretching out and drawing back. The backrest rod connected with the sliding armrest rotates relative to the seat rod to adjust the angle of the chair back. The operation knob is embedded in the front end of the armrest, and the valve opening pin is directly or indirectly pushed to act by shifting the operation knob, so that locking and releasing of the hydraulic rod are controlled, and the smooth and stepless chair back angle adjusting effect is achieved.
