Self-advancing type double pump clogging-free dredging machine

Abstract

A self-feeding double-pump non-clogging dredging machine comprises a floater, a diesel engine, an oil pump, an oil tank, a slurry pump, and a lifting an operating device and six big parts of a machine head, wherein the floater floats on the water surface, the other devices are fixed on the floater, and when two spiral rollers whose spiral directions are opposite rotate, slurry is churned, and the rollers can advance or fall back simultaneously, an axial flow pump conveys slurry to the slurry pump, and the axial flow pump and the slurry pump are combined, which convey slurry to far distance. In the invention three devices which can effectively remove foreign matters, firstly, the two ends of the front end and rear end of the machine head is provided with a disk hobbing-cutter, secondly, a spike which is fixed can be overturned is installed beyond the disk hobbing-cutter, thirdly, the device is a combination of double pumps, a slurry-collecting funnel is arranged in front of a slurry-absorbing opening of the slurry pump, which is provided with an inclined screen mesh to prevent huge granular materials entering into the slurry pump, thereby completely guaranteeing to realize no clogging. The invention works with water, which is applied to dredging work hilly ponds, reservoirs, channels in countryside, and rivers and park lakes in cities.

Description

technical field [0001] The invention relates to a dredging machine, namely a self-propelled double-pump non-clogging dredging machine. Background technique [0002] The development of dredging machines in my country began in the late 1980s. For more than ten years, there are still two common problems: 1. Dredging technologies emerge in endlessly, but the problem of weeds entangled with knives and clogged pumps cannot be solved. solve. According to the search, there are more than 40 patents related to the dredging machine, and its technical characteristics are mainly reflected in the differences in the size, size, weight and transmission mode of the equipment or the technology of excavation and suction and discharge. Few of them have made substantial achievements in the removal of impurities Progress, the current dredging equipment is generally suitable for dredging fish ponds, because there is basically no garbage there. 2. Commonly used dredging equipment has many defects....
