Problems solved by technology
[0002] As the items used in teaching, teaching tools can intuitively reflect the teaching content, allowing students to quickly and conveniently understand the knowledge they have learned. Currently, there are very few multi-head drills for teaching, and students can only go to the construction site of multi-head drills to observe the working conditions of multi-head drills. , which has seriously affected students' understanding and learning of the working principle of the drilling rig

Description
technical field [0001] The invention relates to a teaching tool, in particular to a teaching tool for observing the working conditions of a multi-head drill under different working conditions. Background technique [0002] As the items used in teaching, teaching tools can intuitively reflect the teaching content, allowing students to quickly and conveniently understand the knowledge they have learned. Currently, there are very few multi-head drills for teaching, and students can only go to the construction site of multi-head drills to observe the working conditions of multi-head drills. , This has seriously affected the students' understanding and learning of the working principle of the drilling rig. Contents of the invention [0003] The invention provides a teaching tool capable of conveniently observing the working conditions of the multi-head drill teaching tool under different working conditions. [0004] The present invention is achieved through the following techn...
