一种播种机开沟装置

Ditching device for seeder

Abstract

本实用新型属于播种机技术领域,具体地讲公开了一种播种机的开沟装置。其主要技术特征包括:带有种箱和籽种漏管的机架、周边带有外撇的倒八字形划片的开沟圆盘、将圆盘固定于机架上的转轴和带动圆盘转轴逆向转动的传动机构。该播种机开沟装置由于使用带有八字形划片的圆盘逆向转动开沟,克服了现有技术中楼脚、双圆盘等开沟机构行进开沟时拖挂杂草杂物,影响籽种撒播均匀度问题;又因为该开沟圆盘同机架相对固定,该装置可适用没有翻耕过的土地,并同样保证均匀的开沟深度。该播种机开沟装置具有结构简单和适用的特点。
The utility model discloses a trenching device of a seeding machine, belonging to the seeding machine technical field. The main technical characteristic is that the utility model comprises a rack with a seed box and a seed leaky pipe, a trenching disc with a V-shaped scribing piece which leans to outside, a rotating shaft which leads the disc to be fixed on the rack, and a transmission mechanism which drives the disc rotating shaft to inversely rotate. Because the trenching device of the seeding machine adopts disc with the V-shaped scribing piece which leans to outside to inversely rotate to trench, thus overcoming the problems in the prior art that weeds and miscellaneous materials are drawn and hung on a digging foot, a double-disc and other trenching mechanisms when the digging foot, the double-disc and other trenching mechanisms trench, and the broadcast sowing homogeneous degree of the seeds is influenced; also because the trenching disc and the rack are fixed oppositely, the device is suitable for the soil which is not plowed, and also ensures the even trenching depth. The trenching device of the seeding machine has the advantages that the structure is simple and applicable.
