A rotary processing device that processes a processing object inside a drum and suppresses scattering of particles is described. The rotary processing device includes a drum including a feeding unit for the processing object on one side and a discharge unit for the processing object on the other side and a processor that is connected to a rotation axis member, rotates about a rotation axis of the rotation axis member, and processes the processing object in the drum. The rotary processing device also includes a suppressor that suppresses a gas flow from the other side toward the one side in the drum.

Rotary processing device

A rotary crushing apparatus includes a container (including a stationary drum, a rotating drum, and a top plate) into which a processing object containing raw material soil is fed. A rotating shaft extends in the vertical direction, and an impact member rotates in the rotating drum by the rotation of the rotating shaft to crush the processing object. Then, the rotating shaft is provided in such a way as to penetrate the top plate, and the rotating shaft is rotatably held via ball bearings provided in the vicinity of the top plate. In addition, the lower end of the rotating shaft is a free end.

Rotary crushing apparatus

A positioning method for positioning a first device and a second device separated from the first device is described. The second device is moved so as to approach the first device, a first mark on the first device and a second mark on the second device are imaged, and information is output based on the imaging the first mark and the second mark.

Mixing device

A scraper vehicle is described that can contribute, with a relatively simple and low-cost configuration, to shortening of a construction period, reduction of construction cost, and the like without travel being disabled easily. The scraper vehicle includes an auxiliary drive system that supplies, in excavation by the scraper, a driving force to at least part of traveling wheels of the scraper vehicle. The driving force is supplied constantly or in accordance with a travel resistance of the scraper vehicle.
