The utility model discloses a double disk opener in special scraping, scraping the soil disc (7) and (8) respectively, the scraper disc distribution shaft (9) connected to the two connecting arm (5) of the external bottom, scraping plate and the disc opener is attached to the connecting arm; the upper end connected to the connecting plate (4), spring (6) at both ends of the long hole are respectively inserted into the two connection inside of the arm, the other end of the connecting plate by bolts (3), (2) connecting nut gasket. The scraping disc of the device is rotated when working, scraping soil friction resistance is small, and the effect of scraping is good, and the scraping disk has four larger holes, which is good for the scraped soil to fall completely, and does not cause two blockage. The device scrapes the soil tray by the spring plate to give the appropriate pressure, can maintain the gently fit with the ditching disc, can not only scrape the soil completely, but also does not have the high pressure and the tight force to accelerate the abrasion, also does not increase the disk rotation resistance. The device has the advantages of simple structure, convenient installation and operation, adjustable angle of soil scraping and strong applicability.
【技术实现步骤摘要】
双圆盘开沟器专用内刮土器
本技术涉及一种农业机械,具体说是一种双圆盘开沟器专用内刮土器。
技术介绍
双圆盘开沟器已成为免耕播种机的首选开沟器,但双圆盘开沟器的圆盘容易粘土,如果不及时将粘附的土刮掉,会使圆盘堵塞。现在的刮土器都存在安装维修不方便,寿命短,易磨损,磨损后刮土板与圆盘的间隙越来越大,刮土效果越来越差,磨损严重后甚至刮不到土。
技术实现思路
本技术的目的在于提供一种双圆盘开沟器专用内刮土器,它可安装在免耕播种机的双圆盘开沟器连接机构上,两个圆形刮土盘分别与开沟器的两个圆盘外端贴合,当开沟圆盘转动工作时,刮土器的刮土盘将粘附在圆盘上的泥土刮掉,可有效防止双圆盘发生堵塞、卡死现象。本技术的技术方案如下:一种双圆盘开沟器专用内刮土器,它由与开沟器连接装置、大小刮土盘、联接板、联接臂、弹簧片构成;所述的大刮土盘及小刮土盘分别经销轴连接在两联接臂的外部下端,刮土盘面与开沟圆盘贴合在一起;联接臂上端挂接在联接板上,弹簧片的两端分别插入两联接臂内侧的长孔中,用于撑开两联接臂,联接板的另一端经长螺栓、大垫片连螺母。上述的联接臂上端设挂钩,在联接板上与联接臂连接处设半圆形回钩,联接臂挂在联接板的半圆形回钩上,联接臂可围绕联接板活动。上述的大刮土盘及小刮土盘分别开4个孔。本技术的优点在于:1、本装置的刮土盘工作时是转动的,减小了刮土板与圆盘之间的摩擦阻力,刮土效果好。2、本装置的刮土盘开有四个较大的孔,该形状有利于刮掉的土完全掉落,不会产生二次阻塞。3、本装置刮土盘由弹簧板施以适度的压力,能与开沟圆盘保持轻轻贴合,无论圆盘角度如何变换,刮土器都能与之贴合,可将圆盘开沟器 ...
