Postpositioned reversal ditching machine

Abstract

The invention discloses a postpositioned reversal ditching machine matched with a hand trailing, comprising an intermediate transmission case and an input gear, rotary cutters are fixed on the shaft ends of the power output shaft at two sides of the lower part of the intermediate transmission case; a splash guard is arranged at the front upper part of the rotary cutter; a dirt shoving board is arranged at the rear lower part of the splash guard; a tail pulley is fixed on the splash board; the width of the part of the intermediate shaft through which the rotary cutter passes is 25mm-50mm; as the rotary cutters are arranged on the two sides of the intermediate transmission gear, the bottom of the intermediate transmission case can be lowered to the ditch, the rotary diameter of the rotary cutter can be reduced, the ditching depth can reach the rotary radius of the rotary cutter; and in rotary cutting, the soil flow splashes toward the rear upper parts of the two sides along the splash guard, therefore, the invention has even soil splashing, no crusting soil beside the ditch, low power consumption, high effect, strong adaptability and convenient operation.

Description

technical field [0001] The invention relates to a rear reverse ditching machine matched with a hand drag, which is used for farmland ditching and belongs to agricultural machinery. Background technique [0002] At present, there are many types of trenchers that are matched with hand-trailers. According to the supporting form of equipment, there are front-mounted and rear-mounted types. The front-mounted trencher is installed on the engine frame. The front of the unit is heavy and the rear is light. The operator is very laborious when making a heavy turn and turning around. At present, the rear-mounted ditching machine is still mostly modified with a rotary tiller. The ditching machine modified with a rotary tiller rotates forward to cut the soil, and there are shallow trenches and broken soil in the ditch. More, the soil cannot fly away, and falls on both sides of the ditch. The quality and effect of ditching are very poor. After the operation, the ditch needs to be cleaned ...
