The invention relates to a planter comprises a cross beam, and the connection between the beam and the planter opener handle is characterized in that the upper end of the column, the column is composed of a cylindrical pin handle hinged on the cross beam of the seeder, and the lower end of the opener is fixedly connected with the crossbeam planter in columns are arranged on the both sides in the handle before the limit block and the back stop block, so that when the handle to the front column swing limiting block, the opener is right at the tip just below the cylindrical pin, when the swing angle of handle column by former limiting blocks placed after the limiting block, the handle column is 8 ~ 10 degrees, an additional adjustment spring, the upper end the adjustment of the spring is fixed on the seeder beam and positioned before the limit of a front end, the other end is hinged on the lower part of the column is provided with a handle, wet soil after furrow opener under reflux incision, the fertilizer guiding tube, the duct at the lower end of the probe into the opener, and the guide pipe is positioned at the front end of the pipe for guiding fertilizer The fertilizer inlet of the fertilizer guiding pipe is lower than the seed metering opening of the seed guiding pipe. The invention has a furrow at the same time, with different seeding depth at the same time, and has good work performance.
【技术实现步骤摘要】
本专利技术涉及一种播种机用开沟器,属于农业机械
技术介绍
开沟器作为播种机的重要部件,常用开沟器为固定位置的开沟方式,该方式由于 入土角不变,只能适应单一耕作条件下如已耕地的播种要求,对于目前推广的免耕播种,由 于入土角固定难以保证开沟深度,限制了播种机应用的通用性。其次,由于目前播种多为种 肥同施,而且采用的是行间施肥,不仅增加了播种机结构的复杂性,而且由于种、肥开沟器 间距较小,在免耕播种过程经常出现开沟器前秸秆、杂草的拥堵问题,严重影响了播种机的 作业质量,有时甚至不能播种。另外,由于行间播种距离植株较远,也影响了肥料的利用率。松土铲型开沟器是目前国内玉米免耕播种机最常用的开沟器,其具有工作质量稳 定,但是容易堵塞;且对不同地表状况的适应性差;圆盘式开沟器虽然不存在拥堵问题,但 是由于其入土性差,对于不同地况其开沟深度很难保证。
技术实现思路
本专利技术的目的是提供一种能克服上述缺陷、提高播种机的适应性、工作性能优良 的播种机用开沟器。其技术方案为包括播种机横梁、开沟器和连接在播种机横梁与开沟器之间的柄柱,其特征在于 柄柱的上端是由圆柱销铰接在播种 ...
【技术保护点】
1.一种播种机用开沟器,包括播种机横梁(1)、开沟器(4)和连接在播种机横梁(1)与开沟器(4)之间的柄柱(3),其特征在于:柄柱(3)的上端是由圆柱销(9)铰接在播种机横梁(1)上,下端与开沟器(4)固定连接,播种机横梁(1)在位于柄柱(3)的两侧设有前限位块(5)和后限位块(6),使得当柄柱(3)摆到前限位块(5)时、开沟器(4)的尖端正好处于圆柱销(9)的正下方,当柄柱(3)由前限位块(5)摆到后限位块(6)时、柄柱(3)的摆动角度为8~10°,增设调节弹簧(2),调节弹簧(2)的上端固定于播种机横梁(1)上、且位于前限位块(5)的前端,另一端铰接在柄柱(3)的下半部 ...
