Description

粉碎农田砾石的刀头 技术领域
本实用新型涉及农用器具领域，具体涉及一种粉碎农田砾石的刀头。
背景技术
农田中的砾石大小不一，且形状为不规则形状，在对农田中的砾石进行粉碎的时候，一般的粉碎装置的齿头下方的坡面多为平面形，很难与砾石形成良好的接触。如中国专利授权公告号CN 204571988 U公开了一种刀头，刀头本体和由耐磨材料制成的齿头，所述齿头安装在刀头本体头部，还包括硬质合金体，所述硬质合金体安装刀头头部且位于齿头下方，所述硬质合金体上设有与底面摩擦的坡面。由于坡面为平面形，无法对砾石进行良好的固定，从而降低影响粉碎速度。
实用新型内容
本实用新型要解决的技术问题解决上述现有技术的不足，提供一种能够快速粉碎农田砾石的中的农用刀头。
为了解决上述技术问题：本实用新型采用的技术方案是：一种刀头，包括刀头本体，所述刀头本体头部设有由耐磨材料制成的两个第一齿头，所述第一齿头下方设有与地面摩擦的坡面，所述坡面向内凹陷形成延坡面向上的凹槽，所述第一齿头之间还设有第二齿头，所述第二齿头的位置与坡面的凹槽相对应。
坡面中间向内凹陷，使坡面与砾石的的接触更加稳固，从而使齿头能快速粉碎砾石，且在凹槽的对应位置增加齿头，还可以提高粉碎 速率。
做为本实用新型的优选，所述第二齿头由硬质合金材料制成。使第二齿头可以粉碎硬度较高的砾石。
作为上述技术方案的进一步优选，所述第二齿头的体积的为第一齿头的1/4～1/2。该结构使得第二齿头可以粉碎较小的砾石，且可以对经过第一齿头粉碎过得砾石进一步进行粉碎。
作为上述技术方案的改进，所述刀头底面设有用于连接刀座的螺孔，刀头底面呈“V”型向内凹陷。“V”型底面使刀头与刀座安装更加牢固。
附图说明
图1为本实用新型的结构示意图；
图2位本实用新型的俯视图；
图3为本实用新型的主视图；
图中所示：1、刀头本体；2、第一齿头；3、坡面；4、第二齿头；5、凸起。
具体实施方式
以下结合附图对本实用新型的具体实施方式做详细说明。
如图1、2所示，本实用新型的粉碎农田砾石的刀头，包括刀头本体1，刀头本体1的头部设有两个第一齿头2，第一齿头2可以与刀头本体1一体成型，也可以采用耐磨材料制成，比如硬质合金材料，第一齿头2可以粉碎普通的砾石。两个第一齿头1之间还设有第二齿头4，第二齿头4的体积为第一齿头2的1/2到1/4之间，第二 齿头4由硬质合金材料制成，齿头的下方设有与地面摩擦的坡面3，坡面3的中间部分向内凹陷形成凹槽，凹槽延坡面方向向上，第二齿头4的位置与凹槽相对应，整个坡面的纵向截面可以呈“U”型,也可以是其他的形状。坡面中间向内凹陷，使坡面与砾石的的接触更加稳固，从而使齿头能快速粉碎砾石，且在凹槽的对应位置增加由硬质合金材料制成，且尺寸较小的第二齿头，可以对凹槽中较小的砾石进行粉碎，且凹槽可以对其中的砾石起到良好的固定作用，配合第二齿头，可以快速粉碎凹槽中的砾石。
刀头本体1的上表面上设有一个楔形的凸起5，凸起5可以与刀头本体1一体成型，也可以采用焊接的方式固定在刀头本体1上，当焊接在刀头本体上时，凸起可以采用硬质合金材料制成，增加耐磨性，凸起可以减少刀头上表面与地面接触产生的磨损。
刀头本体1的下底面设有连接刀座的螺孔，下底面也向内凹陷，呈“V”型，如图3所示，当然也可以是其他的形状，“V”型底面使刀头与刀座安装时更加牢固。
综上，本实用新型的粉碎农田砾石的刀头凹陷坡面的设计、多齿头结构提高了粉碎效率，“V”形底面设计有利于与底座的安装牢固。
