The invention discloses a construction solid waste pick-up box and a recovery processing device thereof and belongs to the technical field of construction solid waste recovery and utilization. The construction solid waste pick-up box comprises a processing box and a collecting box arranged at the front end of the processing box. The processing box comprises a box body, and a conveying device, a crushing device and a screening device arranged in the box body. The collecting box comprises a shell, two scrapers and three cutters. The two scrapers are located at a front opening of the collecting box and are used for scraping the construction solid waste into the processing box from the front end of the collecting box to the back end of the collecting box. A first rotating shaft drives the three cutters to move up and down simultaneously. The three cutters are separately located between two sides of the two scrapers and between the two scrapers in a top view direction of the collecting box.The construction solid waste pick-up box can scrap and pick up the construction waste automatically and efficiently, can prevent jamming and is suitable for different field terrains.

The invention discloses a rare earth crushing device for rare earth waste recovery, and relates to the technical field of rare earth waste recovery. The rare earth crushing device includes a base plate, and a material collecting box is placed on the upper surface of the base plate. A first machine case and a second machine case are separately arranged on the opposite sides of the material collecting box, and a crushing box is fixed between the first machine case and the second machine case. The crushing box is arranged above the material collecting box, and the bottom wall of the crushing boxis of a semi-circular structure. A discharge opening is formed in the bottom wall of the crushing box in the length direction, and matching openings are formed in the opposite side walls of the crushing box. The matching openings are arranged in the lower part of the crushing box, and inner gear rings are fixed to the outer edges of the matching openings. A roller is rotatably installed in the crushing box in the length direction, and the outer wall of the roller is attached to the bottom wall of the crushing box. The rare earth crushing device is simple and reasonable in structure design andconvenient to operate, effectively improves the crushing effect of rare earth waste, and has high market application value.

The invention provides environmental protection equipment for cleaning and recovering hogwash. The environmental protection equipment is characterized in that a partition board is transversely fixed in a box body and divides the box body into an oil collecting chamber and an oil storing chamber; an oil-water pipe is fixed in an oil-water hole in the bottom surface of a filtering box, oil collecting pipes are fixed in oil holes of the partition board, the oil collecting pipe on the partition board is in sealed connection with an expansion pipe, a filter is mounted in the filtering box, an oil swallowing floater and a heating pipe float on the hogwash surface in the oil collecting chamber, an oil collecting pipe on the oil swallowing floater and the oil collecting pipe on the upper surface of the partition board are connected through the expansion pipe, an oil pump for conveying the hogwash oil is mounted in the oil storing chamber, and observation windows and an water outlet hole are formed in the box body. The environmental protection equipment has a concise structure, a good industrialized market prospect and high commercial value and is very convenient to manufacture and use; the collected hogwash oil does not contain water, solid-liquid separation and oil-water separation are simultaneously realized by one set of equipment, and kitchen waste is recovered to be used as industrial raw materials; pollution emission is reduced, a kitchen is free of peculiar smell, the environment is protected, and the equipment is the first choice for kitchen waste recovery.

The invention provides a capacitor element detection device and method. The device includes a conveying mechanism, a first detection mechanism, a swing arm mechanism and a waste recovery mechanism, the first detection mechanism and the swing arm mechanism are arranged in sequence along the conveying direction of the conveying mechanism, the waste recovery mechanism is located under the swing arm mechanism, the first detection mechanism includes a first detection sheet group, a second detection sheet group and an insulating spacer located between the two, each of the first detection sheet group and the second detection sheet group includes a short circuit detection sheet and a polarity detection sheet, and the conveying mechanism clamps a capacitor element to move to the first detection mechanism, so that two guide pins of the capacitor element enter between the insulating spacer and the first detection sheet group and between the insulating spacer and the second detection sheet group respectively to perform short circuit detection and polarity detection; and the swing arm mechanism is used for opening a conveying clamp according to a detection result, so that the capacitor element falls into the waste recovery mechanism. The capacitor element detection device and method provided by the invention can realize automatic detection and recovery of the capacitor element.
