AI Technical Summary

Technical Problem

Existing leaf sampling tools are inefficient in outdoor environments without power supply, and the power tools have limited battery life, which cannot meet the needs of long-term work. At the same time, the sampling efficiency and sample preservation integrity are insufficient.

Method used

A blade sample collection and sealing integrated device was designed. It uses a manually pushed guide rod to drive the blade to cut the blade, and a return spring for automatic reset, so as to realize continuous collection without power drive. The magnetic sealing cover ensures the sealing of the sample. The structural design improves stability and convenience.

Benefits of technology

It improves leaf collection efficiency, is suitable for outdoor environments without power supply, ensures sample integrity and preservation quality, and reduces maintenance costs.

Abstract

This utility model belongs to the field of blade sample collection technology, specifically relating to a sealed integrated device for blade sample collection, comprising: a receiving cavity; a connecting seat connected to the top of the receiving cavity, the connecting seat having a clearance groove in the middle; a receiving cavity communicating with the clearance groove in the middle of one side of the connecting seat; a sliding plate located in the receiving cavity, a blade fixed at the front end of the sliding plate, and a guide rod at the rear end of the sliding plate, the guide rod passing through the connecting seat and slidingly guiding the connecting seat. When collecting blade samples, the blade directly enters the receiving cavity through the clearance groove of the connecting seat. Pushing the guide rod drives the blade to cut the blade, and the cut blade falls directly into the receiving cavity without manual transfer, reducing operation steps. Furthermore, with the automatic reset function of the return spring, the blade can quickly return to its initial position after a single cut, supporting continuous multiple collections and significantly improving the collection efficiency of batch samples.
