Ridging and profiling device for potato planter

Abstract

Potato planter ridge profiling device, including two square frames arranged side by side, at least two lifting lugs are arranged side by side under one end of the frame, the lifting lugs are set in pairs, and a U-shaped adjustment seat is also set under the frame , There is a gap between the adjustment seat and the bottom surface of the frame. The bottom of the adjustment seat is vertically provided with a bolt whose upper end extends into the gap. The lower end is connected with the width adjustment slot of the plow arm which can move up and down along the positioning pin. The positioning pin is covered with a spring whose lower end contacts the width adjustment slot of the plow arm. The plow arm is installed on the width adjustment slot of the plow arm. One end passes through the gap between the adjustment seat and the frame, stretches between the two lifting lugs arranged in pairs, and is connected with the two lifting lugs, and the plow arm can rotate around the pin. The ridge profiling device of the invention can follow the profile according to the change of the shape of the ground surface, improves the ridge quality and the stability of the complete machine operation, and has a simple structure and strong adaptability.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a ridge forming device used on a potato planter, in particular to a ridge profiling device for a potato planter. Background technique [0002] Commonly used potato planters are composed of a frame, a seeding system, and a common ridge device. All components are installed on the frame and are rigidly connected. The ridge device cannot operate with the ups and downs of the ground surface. Working on the terrain with unevenness on the ground, the shape of the raised ridges is not high, and the soil adaptability is poor, which directly affects the emergence rate of potatoes, resulting in a reduction in potato production. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the object of the present invention is to provide a ridge profiling device for a potato planter. After being connected with the potato planter, it ca...
