The present invention relates to a duck mouth type seeder. It includes the seeding device, the inoculation cup and the roller, the duck mouth is evenly arranged on the outer ring of the roller, the two adjustable guide plates are installed on the shaft side end of the seed picking device, and the bearing wheels are fitted between the two adjustable guide plates. The duck mouth includes the fixed seat, the rotating plate and the dial rod, the fixed seat is fixed on the outer ring of the drum, the fixed seat and the rotating plate are articulated at one end of the dialing rod. The other end of the dialing rod is reached between two adjustable guide plates. The dial is equipped with a spring that controls the rotation of the rotating plate. When the roller rotates, it drives the dialing pole of each duck's mouth. When the other end of the dialing rod hits the bearing wheel, the dialing rod opens the duck's mouth with the spring of the bearing wheel under the resistance of the bearing wheel. With the rotation of the bearing wheel, the duck mouth gradually opens. When the other end of the shifting lever is detached from the bearing wheel, the duck mouth is closed. The invention is not restricted by the soil environment, and ensures the precision, precision and precision of the seed arrangement, simple structure and convenient use, greatly improving the quality and efficiency of the sowing work, so as to meet the requirements of the development of modern agriculture.

鸭嘴式播种器
本专利技术涉及农业机械,具体是一种不受土壤环境影响,排种精确、精准、精量的鸭嘴式播种器。
技术介绍
目前市场上各种播种机种类繁多,播种机上的鸭嘴一般都是通过压板进行播种,在滚筒转动过程中,通过滚筒外圈上的压板与土壤摩擦接触,在重力作用下,压板受到土壤的反作用力挤压并通过弹簧张开鸭嘴,但是由于农业种植情况土壤环境复杂,很难保证压板受到挤压力均衡,特别是土壤松软的情况下,鸭嘴很难张开,造成种子吐不出来,很难满足农艺要求,给农业生产、生活带来巨大困难和很大损失,直接影响农业发展。
技术实现思路
本专利技术旨在解决上述问题,从而提供一种不受土壤环境影响,保证排种精确、精准、精量的,可旋转自动开启的鸭嘴式播种器。本专利技术解决所述问题,采用的技术方案是:一种鸭嘴式播种器,包括取种器、接种杯、滚筒,滚筒外圈上均匀设置有鸭嘴,滚筒一侧固定安装有滚筒支座,滚筒支座通过取种器固定轴承套装在取种器的取种轴上,接种杯固定安装在滚筒内圈并且将取种器外圈罩住,滚筒在滚筒支座的带动下转动,同时带动接种杯相对取种器转动,取种器的轴侧端分别固定安装有两片可调导板,两片可调导板之间通过螺栓、隔套固定安装有轴承轮;鸭嘴包括固定座、转板、拨杆,固定座通过螺栓固定安装在滚筒外圈上,固定座和转板铰接在拨杆的一端,拨杆的另一端伸入两片可调导板之间并且与轴承轮相适应,拨杆上设置有控制转板转动的弹簧,滚筒转动时,带动每个鸭嘴的拨杆转动,当拨杆的另一端撞到轴承轮时,在轴承轮阻力作用下,拨杆通过弹簧打开鸭嘴,随着轴承轮的转动鸭嘴逐渐张大,当拨杆的另一端脱离轴承轮时,鸭嘴闭合。采用上述技术方案的本专 ...
