Description

The collecting arm of the drift boat

technical field

The invention relates to a collection device used in the cleaning of urban and rural river networks, in particular to a collection device for collecting floating objects on a cleaning ship.

Background technique

At present, the main working method of the drift cleaning equipment in urban and rural river networks is to cut the aquatic plants, use the collection arm or collection rake to gather them, and then use the automatic conveyor belt to salvage them and send them to the cabin, and finally carry out corresponding treatment and stacked. Among them, the collection arm generally adopts an integral structure, which can fully play its role at a certain water depth. However, when the cleaning and drifting equipment is close to the river bank or shoal, due to the slope of the revetment, or the depth of the shoal is not enough, the overall form of the collection arm will first touch the underwater river bank or river beach during the swing and open process, and cannot reach the entire width of the water surface. Due to the low flow rate of water in the shoal, it is very easy to gather floating garbage, which has become a difficult point in the current work of cleaning and drifting.

There are two commonly used methods for garbage collection near the shore and shallows. One is to collect rakes, but the requirements for operators are high, and it is not flexible enough. Obviously, both methods are less efficient.

The upper layer collecting arm is located above the lower layer collecting arm. The length of the upper layer collecting arm is greater than the length of the lower layer collecting arm. Hinged, one end of the control cylinder of the lower collection arm is hinged with the lower collection arm, and the drive motor is connected to the rotating support shaft. The rotating support shaft is formed by axially connecting the upper shaft and the lower shaft. The shafts are connected in sequence, the upper layer collecting arm is rotatably supported on the upper shaft, and the lower layer collecting arm is rotatably supported on the lower shaft.

The upper collecting arm includes an upper swing arm frame, an upper driving rotation gear, an upper driven shaft, an upper driven rotation gear and an upper chain, wherein the upper driving rotation gear is fixed on the upper shaft, and the upper driven shaft is rotatably supported on the upper The swing arm frame is away from the upper shaft end, the upper driven rotating gear is fixed on the upper driven shaft, the upper chain is connected end to end to form a ring, and meshes with the upper driving rotating gear and the upper driven rotating gear respectively; the lower layer collects The arm includes a lower swing arm frame, a lower driving rotation gear, a lower driven shaft, a lower driven rotation gear and a lower chain, wherein the lower driving rotation gear is fixed on the lower shaft, and the lower driven shaft is rotatably supported on the lower swing arm frame away from the lower shaft end, the lower driven rotating gear is fixed on the lower driven shaft, and the lower row of chains is connected end to end to form a ring, and meshes with the lower driving rotating gear and the lower driven rotating gear respectively.
