【技术实现步骤摘要】
羊用子宫颈输精枪
本技术属于畜牧器械领域,具体涉及一种羊用子宫颈输精枪。
技术介绍
在养殖场对牛只采用人工授精技术中,配种受精工作也是相对较为重要的一个环节,而输精枪在人工授精操作中又是很重要的工具;输精枪的设计是否合理关系到输精工作顺利与否。山羊人工授精技术发展的瓶颈在于山羊精液冷冻保存的效率低下及输精部位的不合理,精液冷冻保存技术的进步依赖于长期的研究,短期内尚难达成。而输精部位的改善则可依赖于输精器械的改进及输精细管的改变,山羊子宫颈极细,即使在发情状态下,也难于容纳现有输精器械的插入,若强行插入,会造成子宫颈出血,对精子造成免疫,降低输入精子的数目,不利于羊只妊娠。
技术实现思路
本技术的目的是为了解决上述问题,提供一种羊用子宫颈输精枪。实现上述目的所解决的技术方案是:羊用子宫颈输精枪,包括输精枪体,所述的输精枪体内部设有输精推杆,所述的输精推杆中部设有凸起;所述的输精枪体上部与输精枪盖镶嵌连接,所述的输精推杆上部贯穿所述的输精枪盖,且所述的输精推杆上部与输精推柄螺纹连接;所述的输精枪体下部与螺纹套管上部相连接;所述的螺纹套管下部与输精枪头上部螺纹连接;所述的输精枪头内部设有冻精细管,所述的冻精细管内部装有海绵塞;其特征在于,所述的输精枪头包括枪头尖端和枪头锥端。进一步的,所述的枪头尖端外径为2.0~2.4毫米的空心圆柱管,且所述的枪头尖端长2~3厘米;所述的枪头尖端设有倒圆角。进一步的,所述的枪头锥端设有圆锥度为0.05的圆锥台,圆锥台的上圆锥面直径为5.2.0~5.5毫米,圆锥台的下圆锥面直径为2.0~2.4毫米,且所述的枪头锥端长为5~8厘米。本 ...
