Environment-friendly and efficient dredging and fertilizer preparation equipment for lake and river course treatment

Abstract

The invention discloses environment-friendly and efficient dredging and fertilizer preparation equipment for lake and river course treatment. The equipment comprises a bracket, a dredging mechanism, adehydration mechanism and a fertilizer preparation mechanism, wherein a sliding sleeve is slidably arranged on the bracket, and is connected to a driving mechanism mounted on the bracket, the top endof a bushing is connected to the bottom end of a steel wire rope, two groups of grab buckets are respectively and symmetrically arranged at the bottom end of the bushing and are movably connected tothe bottom end of the bushing, a first hydraulic cylinder is arranged on the top surface in the bushing, a sealing plate is arranged in the bushing, the output end of the first hydraulic cylinder penetrates through the sealing plate in a sliding mode and is connected with a movable plate, sliding grooves matched with the movable plate are formed in the side walls of the two sides of the bushing, and are connected to the movable plate in a sliding mode, the two sides of the movable plate are respectively and movably connected to one end of a movable rod, and the other ends of the movable rods are movably connected to the grab buckets. According to the invention, the equipment has advantages of high automation degree and convenient operation, and substantially improves the river course sludge cleaning efficiency and the quality of the product when the sludge is prepared into the fertilizer.

Description

technical field [0001] The invention belongs to the technical field of river course management, and relates to dredging and fertilizing equipment, in particular to an environment-friendly and efficient dredging and fertilizing equipment for lake and river course harnessing. Background technique [0002] River dredging generally refers to the treatment of rivers, which belongs to water conservancy projects. Through mechanical equipment, the silt deposited on the bottom of the river is cleaned away, so as to play the role of dredging. [0003] The comparative document CN105275036A discloses a river channel dredging fertilizer system, which is characterized in that it includes a crawler dredging device, a sludge sorting device and a sludge processing device arranged in sequence, and the sludge sorting device and the sludge processing device are provided with On the hull, one end of the crawler dredging device extends into the river channel from the tail of the hull, which has ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, during the actual operation of the dredging and fertilizing equipment for river treatment, the bucket has a relatively large movement resistance under water, and the water in the bucket cannot be discharged in time. , thus increasing the energy consumption during desilting, and after digging up the silt from the bottom of the river, the water cannot be drained in time, which increases the burden of the post-fertilization process; the degree of automation is low when dewatering the silt, and manual labor is required Auxiliary participation will also make the dehydration effect poor, which will affect the effect of fertilizer production on sludge in the later stage; in addition, in the process of fertilizer production, when the amount of oxygen inflow and the amount of bacterial solution added are not enough, it is necessary to suspend the operation of the equipment and restart Continue to add, so that the operation of the fertilizer making equipment is not coherent and convenient; when the sludge is fully stirred and mixed with the bacterial solution and oxygen, due to the nature of the sludge, the sludge sticks to the inner wall of the equipment, making the sludge stirring not uniform and resulting in fertilizer efficiency. low, and the feeding is not clean enough, and an environmentally friendly and efficient dredging equipment for lake and river treatment is proposed
