Tool changing device for jujube tree grafting

Abstract

The invention provides a tool changing device for jujube tree grafting. The device comprises a cutter set, a cutter head, a cam mechanism and a power assembly, the cutter set comprises a scraper, a first breaking knife, a second breaking knife and a cut-off knife, the cutter head is of a ring structure, the cam mechanism is arranged in the center of the cutter head, and the cam mechanism and the cutter head are relatively independent. Four guide rail grooves are evenly formed in the cutter head, the scraper, the first breaking cutter, the second breaking cutter and the cut-off cutter are slidably installed in the guide rail grooves respectively, limiting pieces are arranged at the tails of all cutters in the cutter set, the cutter head is connected with the power assembly, and a steering engine drives the power assembly to move so as to drive the cutter head to rotate. When the cutter head rotates, the stationary cam mechanism ejects the cutters out, and the four cutters are cyclically reciprocated, so that the cutter replacement operation is convenient. The device is scientific and reasonable in structural design, safe and smooth in tool changing, diversified and complete in function, small in size, low in weight, convenient to carry and capable of effectively improving the working efficiency of jujube tree grafting.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a knife changing device for jujube tree grafting. Background technique [0002] Jujube tree grafting has the advantages of high reproduction rate, fast seedling raising speed, stable genetic traits, and earlier results. It is one of the methods commonly used to cultivate fine jujube seedlings at present. There are many knives used in the grafting process, which is inconvenient to carry, resulting in low work efficiency. At the same time, the blades are exposed during use, and it is easy to scratch hands when taking them. The knives are exposed to the air for a long time, which reduces the life of the knives. [0003] When jujube tree is grafted, it usually needs to go through several steps of skin scraping, breaching, scion and film wrapping. There are many kinds of knives involved, and the knives need to be replaced frequently, and the plastic film is carried...

AI Technical Summary

Problems solved by technology

There are many kinds of knives involved, and the knives need to be replaced frequently, and the plastic film is carried with them. The operator has safety hazards and low efficiency when switching knives during work.

Most similar devices are designed for a single tool or grafting auxiliary device, which has certain limitations, and different regions have different requirements for the use of tools
