An agent delivery device

Abstract

An agent delivery device is mounted in an excavator, and can be used in match with mechanical equipment provided with hydraulic systems. An agent hopper used for storing an agent is arranged above a cover plate of a distributor of a hydraulic excavator. A spiral conveyor shell penetrates and is connected to the lower part of the agent hopper. A medium mixing container formed by separating the spiral conveyor shell with a valve plate is outside the shell of the agent hopper. An agent and sludge are uniformly mixed, thus achieving an objective of implanting the agent to bottom mud, promoting andactivating dominant microbes of a riverway to allow continuous mass propagation of the dominant microbes, and effectively reducing organic maters, total phosphorus, total nitrogen, COD, and other indexes of black and odorous bottom mud, and therefore, black and odorous phenomena of a water body are eliminated and a riverway self-cleaning capacity is recovered. Compared with traditional outward riverway sludge transportation, the device greatly saves the engineering cost, is convenient and rapid for sludge treatment, allows a black and odorous riverway to become clear, and is of great significance for environment protection.

Description

technical field [0001] The invention relates to the technical field of machinery, and in particular provides a drug delivery device installed on an excavator. Background technique [0002] Urban rivers are an important part of urban water systems, and still play a vital role in urban flood control, drainage, tourism, and navigation. During the operation of the river, a large amount of silt and debris will be deposited at any time. At present, the water quality of the river and the silt at the bottom are black and smelly, which seriously affects the ecological environment. River siltation has increasingly affected flood control, drainage, irrigation, water supply, navigation, etc. In order to ensure the normal performance of various functions, the dredging work is very important. Hydraulic excavators are often used in dredging projects to play their role in stirring silt, cleaning silt, etc. [0003] At present, adding chemicals to the river silt can restore the natural eco...

AI Technical Summary

Problems solved by technology

The disadvantage is that the conveying system designed by the pontoon needs to cooperate with other mixing equipment, and the pontoon and the equipment move together; the disadvantage of the simple conveying system of the hopper is that the powder is output by natural force or stirring force, without pressure, and the powder is not evenly sprinkled into the river water mixed with the silt, and then fail to achieve the purpose of restoring the self-purification ability of the silt
