Dry riverbed sandstone clearing device used for riverway clearing

Abstract

The invention relates to the technical field of riverway clearing, and discloses a dry riverbed sandstone clearing device used for riverway clearing. The dry riverbed sandstone clearing device comprises a fixed base; the right side of the upper end of the fixed base is provided with a rotating table; the upper end of the rotating table is provided with a lifting device; the upper end of the lifting device is provided with a lifting column; the bottom end of the lifting column is provided with a fixed tube; a lead screw is arranged in the fixed tube; the middle part of the lead screw is provided with a lifting block; the two ends of the lifting block are each hinged with a big arm; the bottom end of each big arm is hinged with a clearing bucket; the upper ends of the clearing buckets are connected with a hinge shaft through first connecting rods and second connecting rods; the hinge shaft is arranged at the bottom end of the fixed tube; and the left side of the upper end of the fixed base is provided with a storage box. The dry riverbed sandstone clearing device is reasonable in structure and novel in design; with the cooperation of the installed fixed tube and clearing buckets, thefunctions of efficient excavating and mobile storage of sandstone are achieved, and the efficiency of clearing the sandstone is greatly increased; and the whole device is simple to operate and high in reliability.

Description

Technical field [0001] The invention relates to the technical field of river cleaning, in particular to a dry riverbed sand and gravel cleaning device for river cleaning. Background technique [0002] Rivers are important channels for water to flow from land to lakes and oceans. They are also an important geological force for transporting sediments from land to oceans and lakes. The transportation of rivers is accompanied by sedimentation, forming a wide range of river deposits. The sedimentation process is mainly affected by various factors such as terrain slope, sediment type and sediment transport, river flow and flow pattern, and vegetation. The river sand and gravel are continuously transported and accumulated during the flow of water, thus forming a certain sediment Characteristic sand body sediments. [0003] After the river has dried up, there are more side sand and gravel deposits on the river bed, which needs to be cleaned up in time, so that the river can be dredged whe...

AI Technical Summary

Problems solved by technology

[0003] After the river channel dries up, the river bed has a lot of side sand and gravel, which needs to be cleaned up in time to facilitate the dredging of the river channel when the river comes next time, so that the river water can flow into the river in time. At present, manual cleaning is a waste of manpower, or using machinery to clean up in the river channel may sink into the river channel in the sludge, making cleaning inconvenient

Chinese patent (notification number: CN208594587U) discloses a dry riverbed gravel cleaning device for river channel cleaning, including a device body, a chute is opened on the right side of the device body, and the inner top wall of the chute is fixedly embedded with The first bearing, the inner bottom wall of the chute is fixedly embedded with the second bearing, the upper surface of the device body is fixedly connected with the first motor, and the output end of the first motor is fixedly connected with the first threaded rod, so The end of the first threaded rod away from the first motor runs through the first bearing and extends to the inside of the chute, and the outer surface of the first threaded rod is fixedly connected with the inner ring of the first bearing, although the device can to a certain extent To clean the gravel in the river bed to a certain extent, but in actual operation, the gravel is not only easy to shake in the bucket, but also the amount of single cleaning is very limited, so further improvement is needed
