Sugarcane planting machine furrow opener

The invention relates to a sugarcane planting machine furrow opener. The sugarcane planting machine furrow opener comprises a vertical furrow opening trowel mainboard frame; the front end of the vertical furrow opening trowel mainboard frame is a sharp corner; the left side and the right side of the vertical furrow opening trowel mainboard frame are provided with side guide plate inserting grooves in vertical direction; the side guide plate inserting grooves are provided with side guide plates; the left side and the right side of the vertical furrow opening trowel mainboard frame are provided with vertical supporting plates; the upper and the lower ends of the outer side of the supporting plates are provided with fixing sleeves I; the upper and the lower ends of the inner side of the supporting plates are provided with fixing sleeves II; the fixing sleeves II are connected with the fixing sleeves I via pin shafts; the front side of the lower end of the vertical furrow opening trowel mainboard frame is provided with a furrow opener wedge block; the lower end of the vertical furrow opening trowel mainboard frame is provided with a sealing plate; and the sealing plate is connected with the side guide plates so as to form an integral whole via welding. The sugarcane planting machine furrow opener is simple in structure; the side guide plates are smooth; furrow opening resistance is reduced; free dismounting and installation of the side guide plates with the vertical furrow opening trowel mainboard frame can be realized; clearing of foreign materials is convenient; and furrow opening efficiency is increased.
