- Many countries are employing machines similar to that above from
Qingzhou Dongfang. This machine is designed for river weed reduction. It
has a 4.2 meter wide head that operates to a depth of one meter. For
smaller scale river cleaning projects the product is most suitable. For
use on rivers over a thousand kilometers in length, NOx and carbon
monoxide emissions and the cost of diesel fuel becomes a major
Qingzhou Dongfang Environmental Protection Machinery Manufacturing Company Ltd
is a company with 50 employees, 6 technical engineers and 2 professional designers.
The company specializes in the design and manufacturing of environmental protection boats.
They have experimental facilities to develop and test their products.
The company prides itself of a range of boats and a good after-sales
service. These boats sell in over 30 domestic provinces, municipalities and autonomous
regions. They are exported to Indonesia,
Ghana, Vietnam, North Korea, Sudan,
Morocco, Mongolia and many other countries and regions.
This design of River Cleaning Boat is used for collecting garbage that
is floating on rivers and other waterways, single stage filtering and transporting of the
salvaged material , including cutting water plants.
Their automatic river cleaning boat is of single bottom, single deck, transverse frame
design, which is fabricated in welded
steel. When they say automatic, they refer to the machinery that lifts the
river waste and deposits it in the rear of the craft. They do not mean
that the craft operated on its own. It is a manually operated vehicle,
rather than an autonomous vehicle.
There boat is mechanically driven via hydraulic pumps and motors from a
diesel engine. The main design features are a swinging collection arm (or
booms) at the front of the vessel and a stainless steel
belt conveyor that sits in the water between the booms to lift floating
river waste and deposit it in a holding area with a capacity of 10 tons
and height of 2.5 meters. This sequence is described as automatic. Once
full, the catch is transferred to shore.
The boat moves in the water using paddle-wheels, also driven by hydraulic
- This machine was deployed to clean up a portion of the great river
Ganges in anticipation of the Indian Prime Minister's visit.
Control of the machinery is by multi-way hydraulic valve block. This
allows the operator to engage the cutting collection scissor head and
adjust the water depth, fore and aft elevator. These functions can be made
to work alone or at the same time, sequentially. The hydraulic system is
load sensitive, to be able to balance the power of the engine to reduce
heat build up and so use fuel in the most economical way.
The diesel engine flywheel end drives a double-pump hydraulic oil input to the manual control
valve block. The paddle wheels may be variably controlled when moving
forward for course changes and speed variation, stopped or reversed by the
operator to steer and maneuver the boat, using the hydraulic
Qingzhou Dongfang will work with customers to design a river cleaning boat
to the size of your lake, the type of your weeds, the percentage of weeds you would like to remove, and how quickly you would like to harvest
