清淤机械是用于清理田间渠道和河道的淤泥、沟坡杂草的一种农田基本建设作业机具。在目前的排灌系统中,由于水流、风雨的冲蚀,水中夹带泥沙的沉积,沟渠逐渐淤塞,影响了排灌效能。据调查,粘土地区的田间渠道每年要淤塞10～30厘米厚,砂壤土地区的田间渠道每年要淤30～50厘米厚。在灌区和涝洼区每1～3年就要清淤一次。目 Dredging machinery is used to clean up the field channels and river silt, ditch weeds a farmland capital construction work tools. In the current irrigation and drainage systems, the ditches are gradually clogged due to water flow, erosion by wind and rain, deposition of sediment entrapped in the water, and the drainage and irrigation performance is affected. According to the survey, the field channels in the clay area are blocked 10 to 30 centimeters thick each year, and the field channels in the sandy loam area are silted 30 to 50 centimeters thick each year. Dredging and waterlogged areas every 1 to 3 years will be dredging once. Head
