AI Technical Summary

Technical Problem

In the current tea seedling grafting process, it is difficult to control the hygiene of the rootstock incision device. The blade is easily contaminated with plant sap and bacteria, leading to cross-infection of viruses and a decrease in grafting survival rate.

Method used

Design a cutting device for tea seedling grafting. It uses a gear rack and one-way bearing to realize the automatic rotation and cleaning of the blade. The blade is driven to deflect periodically by a stroke cylinder. Combined with a cleaning pad, the blade edge is automatically cleaned to ensure the cleanliness and sharpness of each cut.

Benefits of technology

It significantly extends the service life of the blades, reduces the risk of tea seedling infection, improves the grafting survival rate, and ensures the smoothness and cleanliness of each cut.

Abstract

The application relates to a tea seedling grafting technical field, in particular to a cutting device for tea seedling grafting, which comprises a base, supporting plates are fixedly connected to the two sides of the base, notches are arranged on the supporting plates in a penetrating mode, sliding blocks are slidingly matched in the notches, a bottom plate is fixedly connected to the sliding blocks in an inclined mode, a connecting shaft is rotatably arranged in the middle of the bottom plate, a blade is fixedly connected to the connecting shaft, and a driving structure is arranged at the bottom of the bottom plate and used for driving the blade to periodically deflect. The device is used in cooperation with a rack, a gear and a one-way bearing, a cleaning pad is arranged on the path of the blade, the blade is forced to rub against the cleaning pad during the turning and switching process, plant tissues, sap or bacteria residues adhered to the blade can be scraped in time, pollutants can be prevented from being brought into the next notch, and the risk of the grafting survival rate reduction caused by the notch infection of the tea seedling can be greatly reduced.
