Abstract

The invention discloses a demonstration model for observation of operating conditions of a fetcher. In operation of the fetcher, square buckets on a first outer ring and square buckets on a third outer ring scoop sand when passing through the bottom end during clockwise rotation and dump the sand when rotating to the top end, and sand falls into first semicircular buckets; square buckets on a second outer ring and square buckets on a fourth outer ring scoop sand when passing through the bottom end during anticlockwise rotation and dump the sand when rotating to the top end, and sand falls into second semicircular buckets; the first semicircular buckets and the second semicircular buckets are taken out of the fetcher after being filled fully, first semicircular covers, second semicircular covers, third semicircular covers and fourth semicircular covers are open to pour the sand, and then the fetcher is put into a glass cylinder again to continue sand fetching. By the demonstration model, students can directly observe the operating conditions of the fetcher.

Description

Technical field [0001] The invention relates to a model, in particular to a demonstration model for observing the working condition of an object picker when it is working. Background technique [0002] As objects used in teaching, models can intuitively reflect the teaching content, allowing students to quickly and easily understand the knowledge they have learned. Currently, there are very few models of pickers used in teaching, and students can only go to the site to observe the work of pickers Circumstances, this seriously affects students' understanding and learning of fetching equipment. Summary of the invention [0003] The invention provides a demonstration model for conveniently observing the working condition of the fetching appliance during work. [0004] The present invention is realized through the following technical solutions: [0005] A demonstration model for observing the working condition of the fetching device when it is working. The lower end of the telescopic ro...
