Vertical type elastic disk coulter

Abstract

The invention provides a vertical elastic disc opener, which includes a bracket, the bracket includes a first pole, a support plate and a second pole, the bottom of one end of the support plate is fixedly connected with the top of the first pole, and the other end The bottom is provided with an elastic pressing device and an anti-sputtering device. One end of the second pole is rotatably connected to the bottom end of the first pole, and the bottom of the other end is connected with a grooved disc. The elastic pressing device includes a circular top plate, Guide rods, cylinders, pistons, push sleeves, springs and circular bottom plates, anti-sputtering devices including telescopic tubes. The advantages are: according to the actual needs, the height of the ditching plate can be quickly adjusted, which is suitable for ditching work in different soil fields; relying on the spring, the ditching plate can realize elastic ditching according to the actual condition of the soil and ensure the overall ditching Excellent quality; the anti-splashing device is adopted, which can protect the spring as a whole through the telescopic tube, preventing the mud and water from splashing on the spring during the ditching process, increasing the service life and reducing maintenance costs.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vertical elastic disc ditch opener. Background technique [0002] The disc opener is a kind of opener commonly used on agricultural machinery. There is a certain declination between the direction of the disc plane and the forward direction. When working, the disc plane pushes the front soil to the side, and a ditch will be formed behind the disc to achieve the purpose of ditching. The ditch opened is used for sowing or fertilizing. Because the disc opener can push the soil to the side while opening the ditch, it can also be used for furrowing in irrigated fields. The size of the deflection angle of the disc determines the width of the ditch, and the depth of the disc into the soil determines the depth of the ditch. [0003] At present, the existing known technology uses the screw to drive the nut to realize the vertical position adjustment and positioning of th...
