The on-line grinding mechanism of silage cutting table consists of frame, grinding tool mechanism and on-line switching mechanism. The grinding tool mechanism includes handwheel, propulsion bearing, bearing seat, fixed disc and grinding wheel. The on-line switching mechanism includes transmission angle box, electric push rod, push rod, baffle and sliding sleeve. The electric push rod is connected with the push rod and installed on the push rod. Spring, sliding sleeve is placed between springs, sliding sleeve is connected to a fixed plate, the baffle bar is connected to the other side of the fixed plate, the baffle bar is connected to the transmission angle box, the output end of the transmission angle box is connected to the feeding mechanism of the silage cutting table through the transmission wheel, and the input end of the transmission angle box is driven by the transmission wheel and the hay cutter disc on the silage cutting table. The moving wheel is connected. The utility model has a knife grinding mechanism in the existing silage cutting table, realizes on-line grinding of the knife grinding mechanism through an electric shift switching mechanism, greatly improves the working efficiency of the silage cutting table, ensures the cutting effect of the knife head, and has the advantages of reasonable design, low labor intensity of workers and high degree of automation.

青贮割台在线磨刀机构
本技术涉及农用机械
,具体涉及一种青贮割台在线磨刀机构。
技术介绍
割台是青贮饲料收获机的重要组件,割台的刀盘上安装若干刀片,这些刀片在使用一段时间后,刀片刃口会变钝,如果要打磨这些刀片,就需要停机然后拆卸割台,将刀片一个一个取出后才能打磨,费时费力,严重影响青贮饲料收获机的工作效率。
技术实现思路
本技术提供了一种青贮割台在线磨刀机构,以解决现有技术存在的割台的刀盘刀片打磨费时费力的问题。本技术解决其技术问题所采用的技术方案是:一种青贮割台在线磨刀机构,由机架、磨刀机构和在线切换机构组成,磨刀机构包括手轮、推进轴承、轴承座、固定盘和磨刀砂轮,轴承座固定在机架上,推进轴承置于轴承座内,手轮连接在推进轴承一端,推进轴承另一端与固定盘相连,固定盘上安装磨刀砂轮,磨刀砂轮正对青贮割台上铡草刀盘的刀片;在线切换机构包括传动角箱、电动推杆、推杆、挡杆和滑动套,电动推杆与推杆相连,推杆上安装弹簧,滑动套置于弹簧之间,滑动套连接在一个固定板上,挡杆连接在固定板另一侧,挡杆与传动角箱相连,传动角箱的输出端通过传动轮与青贮割台的喂入机构相连,传动角箱的输入端通过传动轮与青贮割台上铡草刀盘的驱动轮相连。上述推杆上安装的弹簧顶端设置压盖。本技术的青贮饲料收获机青贮割台在线磨刀机构使用时,青贮割台前面的喂入机构将作物秸秆或牧草收割并送至铡草刀盘处进行切割粉碎,使用一段时间后如果刀片磨损,可以通过电动推杆将挡杆切换挡位,可以实现传动角箱空转,这样青贮割台的喂入机构停止工作,而铡草刀盘的驱动轮继续运转,然后通过手轮由推进轴承将磨刀砂轮靠近铡草刀盘,这样驱动轮带动铡 ...
