1KH series disctrencherIt is a disc trenching tool for farmland driven by a tractor power output shaft, suitable for planting vegetables, cotton, corn, and other land for trenching and bed making. Due to the use of double disc milling operation, it has excellent operation quality, especially in terms of milling and throwing soil performance. Not only is the soil milled and thrown evenly, but the throwing distance can also be adjusted within the range of 1.2m to 2m; The loose soil cover adopts a two wing angle changing scheme (i.e. the angle between the two wings of the loose soil cover transitions from 100 ° to 90 °), so the milling and throwing of soil are relatively uniform during trenching, and the distance between the two sides of the soil throwing is also basically consistent; Wall cutters are installed on both sides of the cutterhead, and the conversion between trapezoidal grooves and rectangular grooves can be achieved by loading and unloading the wall cutters and the cutter holder; There are two limit devices installed on the suspension arms on both sides of the trencher, which can effectively control the left and right swing of the tractor's lower pull rod, improving the straight line and depth stability of the trencher; Therefore, it can meet the agricultural requirements of various furrow widths for land trenching operations. At the same time, it can also be applied to no tillage operations for various crops, that is, to implement the sequence of sowing first and then trenching on uncultivated land, using the milling soil of the trenching machine to cover the seeds.
