CrimeaPRESS reports:
Specialists from the Crimean Federal University have developed experimental samples of equipment for mechanizing the production of grafted grape cuttings. The head reported this. Department of General Technical Disciplines of the Agrotechnological Academy of KFU Alexey Zavaliy.
The work was carried out within the framework of the strategic academic leadership program “Priority 2030”. One of the devices developed by scientists at the Crimean Federal University is a machine for blinding the buds (eyes) of a rootstock grape vine. Blinding is one of the stages of preparing cuttings for grafting.
The eye-blinding machine is a through-channel into which untreated grape cuttings are manually fed. The mechanism is equipped with two drives: one retracts the cutting, and the second pushes it out after processing is completed. Inside the channel, the raw vine passes through guide cones, between which the eyes are cut using rotating cone cutters in several planes. The cutters are made of polymer material, the rigidity of which is sufficient to cut the buds without damaging the top layer of the vine,” the university press service quotes Alexey Zavaliy.
According to him, the productivity of the experimental machine is many times greater than manual pruning: up to 3,000 cuttings can be processed in an hour. The original mechanism has already received a utility model patent.
In addition, university specialists have developed a semi-automatic device for bunching rootstock, scion and grape seedlings into bunches. It is a standard strapping machine unit, upgraded with a module for tying using a polymer tape. The module allows you to form beams of the correct shape and simplifies the operator’s work.
The speed of the operation is significantly increased. If a person could tie two bundles in a unit of time, now in the same unit of time an operator can connect 20-30 bundlesnotes Alexey Zavaliy.
This machine can also be used to bundle other perennial crops.
