一种用于扎取籽瓜的捡拾齿
本技术属于农业机械配件领域,具体涉及一种用于扎取籽瓜的捡拾齿。
技术介绍
新疆的气候及土壤适宜种植籽用瓜,因其经济价值较高,有利于农民增收致富,所以种植面积不断增加。传统的籽瓜的收获主要靠人工捡拾、集堆,人工掏籽或喂入简单的脱籽机,用工量大,劳动强度高。通常会使用一种具有捡拾齿辊的籽瓜收获作业机,其中捡拾齿辊上设置有多个捡拾齿,用于扎取田间地头的籽瓜。然而,现有技术中的捡拾齿的结构过于简单、不稳定,捡拾齿扎瓜效果不佳,工作效率低下;另外机组作业的安全性方面有所欠缺。中国专利201120205169.2提供的一种籽用瓜捡拾脱籽联合作业机的捡拾齿,捡拾齿由扎瓜齿、齿座和齿座下部的连接固定杆构成;其中,扎瓜齿的形状采用锥状齿或柱状齿,侧面平滑,扎瓜效果有限;柱状齿的齿端设置着锐利的齿尖,作业过程易扎上瓜籽,影响正常作业,同时导致后期清理机械不易,操作不当易扎伤清洁人员;球面座或柱状座或圆台座或锥状齿的齿座与捡拾齿辊辊圈的结合不稳,易滑动甚至脱落。
技术实现思路
针对现有技术中的不足之处,本技术一种用于扎取籽瓜的捡拾齿,主要安装在籽瓜捡拾脱籽联合作业机的捡拾齿辊辊圈上。为了达到上述目的,本技术技术方案如下:一种用于扎取籽瓜的捡拾齿,其特征在于:包括一体成型的捡拾齿主体,所述捡拾齿主体包括依次分布的扎瓜齿、锥状的齿座和连接螺纹杆;所述扎瓜齿末端侧壁设有防脱落纹,所述齿座与连接螺纹杆之间设有紧固防转定位块,所述连接螺纹杆沿轴向安装于捡拾齿辊的辊圈上,扎瓜齿朝外 ...
