Abstract: A device for removing granular material by suction is presented, the device comprising a suction head. The suction head comprises a lower end, an outlet for removing granular material from the suction head, and side walls, extending from the lower end to the outlet. The suction head further comprises one or more nozzles, configured to emit a pressurized fluid for fluidizing granular material, and one or more side inlets for the inflow of fluidized granular material into the suction head. The side inlets are located in a side wall, and the side inlets combined extend over at least 2% of the circumference of the lower end. A method for removal of granular material by suction from a granular material mass is also presented. The nozzles on an outside and the nozzles on an inside of the suction head provide a helical flow in the same direction.

Abstract: A treatment method for a river system in a reservoir area, comprising: S1. determining whether a time from a current date to the rainy season is less than a preset duration; S2. moving a pressure sensor upward; S3. determining whether the pressure data meets corresponding conditions; S4. determining whether a duration of the pressure data is less than the preset duration; S5. determining whether an interval between the current time and the time for collecting pressure/nitrogen and phosphorus is greater than a preset number of days; S6. acquiring an image information of a river bottom, and sending it to neural network model for identification to obtain a depth of a sludge; S7. determining whether the depth of a sludge has reached a dredging depth, if so, starting a sludge pump to clean up; S8. collecting nitrogen and phosphorus concentration, and removing nitrogen and phosphorus when the concentration exceeds a standard.

Abstract: A method of dredging which comprises suspending dredging apparatus 200 from a vehicle 360. The sediment agitating apparatus comprising a chassis 210, and mounted on the chassis are an extractor, sediment agitating apparatus and respective pumps 220, 230. The dredging apparatus 200 is disposed above, but not in contact with a waterbed 340 to be dredged of sediment 350. The sediment 350 is agitated then extracted with the extractor. The dredging apparatus 200 is moved around the water and the extracted sediment 400 is deposited underwater and above the dredging apparatus 200, so that the sediment 400 is transported and deposited away from an area being dredged by the natural movement of the water. Apparatus and use of the apparatus are also described.

Abstract: In order to meet the objective of providing a device (10) and a method for a sediment transfer in waters (80, 81, 90) that works efficiently, a device (10) comprising at least one suction line (12) and at least one receiving means (16) for receiving sediment (70), and furthermore, having at least one pressure line (14) for transferring the received sediment (70) is proposed. Following the at least one receiving means (16), at least one pump device (18) and at least one measuring device (20) for determining a sediment concentration of the received sediment (70) are arranged. The device (10) further comprises a control unit (22) having a first interface (25) for inputting target values (24) and a second interface (26) for the at least one measuring device (20), and determines a sediment concentration in the at least one suction line (12) and/or in the at least one pressure line (14).

Abstract: A tilt adjustable head attachment assembly for a clamshell style bucket for orienting first and second bucket halves at an angle relative to a length axis extending through an elongated and rigid attachment associated with a piece of power equipment, for supporting and manipulating the bucket. A frame has a three dimensional body, upwardly extending pillar mounts located at upper ends of the body and incorporating support shafts for receiving overlapping hinged locations associated with support arms for each of the first and second clamshell bucket halves. A platen is positioned pivotally arranged between the pillar mounts and includes an upper location engaged by an end projection of the elongated attachment. A cylinder is connected to a fixed underside location of the frame at a first end and to the platen at a second end and, upon being actuated, pivotally displacing the platen to in turn angle the frame and supported clamshell bucket halves relative to the excavator attachment according to a desired orientation.
