Forced excavation is not only inefficient, but may also damage the drill bit. In order to solve the above problems, a new type of spiral drilling machine drill bit for frozen soil in cold regions was designed.
发明内容Contents of the invention
本发明的目的就是针对上述现有技术存在的问题，结合农业生产作业使用的实际需求，提供一种新型寒地冻土螺旋式挖坑机钻头，该钻头可以在秋冬时节北方寒地冻土条件下进行挖坑作业。确定选用平刀-锯齿刀组合的刀片形状，设置刀片安装角、刀片入土角为特定值，钻尖采用可以有效减轻刀片压力的锥形小螺旋钻尖，赋予刀片与钻尖高硬度、耐磨性好的高速工具钢，主轴与双螺旋叶片采用高韧性高强度的碳素结构钢。The purpose of the present invention is to provide a new type of cold frozen soil spiral digging machine drill bit in view of the problems existing in the above-mentioned prior art and in combination with the actual needs of agricultural production operations. The drill bit can be used in the frozen soil conditions of northern cold areas in autumn and winter. Carry out digging operations below. Determine the blade shape of the flat knife-serrated knife combination, set the blade installation angle and the blade penetration angle to specific values, and use a small tapered spiral drill tip that can effectively reduce the pressure on the blade, giving the blade and drill tip high hardness and wear resistance It is made of high-speed tool steel with good performance, and the spindle and double-helical blades are made of high-toughness and high-strength carbon structural steel.
为实现上述目的，本实用新型采用下述技术方案：固装有平刀刀片的左螺旋叶片和固装有锯齿刀片的右螺旋叶片分别对称的固装在主轴上，所述的主轴的顶端部固装有圆锥状的钻尖。In order to achieve the above purpose, the present utility model adopts the following technical solution: the left spiral blade with a fixed flat blade and the right spiral blade with a serrated blade are respectively symmetrically fixed on the main shaft, and the top end of the main shaft Fixed conical drill tip.
由于采用上述技术方案，本实用新型提供的一种新型寒地冻土螺旋式挖坑机钻头采用平刀-锯齿刀组合的刀片形状与现有技术相比，碎土能力更强同时又保证碎土的正常升运，适合北方寒地冻土条件下作业需求。Due to the adoption of the above technical solution, the utility model provides a new type of frozen soil spiral excavation drill bit that adopts a blade shape of a flat knife-serrated knife combination. Compared with the existing technology, the soil crushing ability is stronger while ensuring the crushing ability. The normal lifting and transportation of soil is suitable for operation needs in frozen soil conditions in northern cold regions.
