Known knife for grafting plants with two blades Ll

This knife is convenient for carrying out grafting with a lamination of a bark plate, but it is not very suitable for other vaccinations.

A known knife for grafting plants containing a steel blade, made in the form of a bracket with wings. The cutting of wood by cutting a graft or sub is done by cutting.

However, due to the fact that the wings of the staple are located in the same plane when cutting the cutting, cutting surfaces form perpendicular to the fibers of the wood, especially in the area adjacent to its bark, i.e. just where it is most undesirable.

In addition, the knife creates a small cut surface in the cross section of the cambial layer of the cutting. This is one of the reasons for poor growth of the lead with the stock due to the insufficient surface area of the combination of the cambial layers of the grafted components, especially with the incomplete coincidence of their diameters.

The purpose of the invention is to improve the quality of the tackings by obtaining a smoother surface in all sections of the copulative cut.

The goal is achieved. by that. the side wings of the knife staples are angled to each other, and in the place of their mating there is an ellipsoid protrusion, with the base of the wings having sharpened bevels forming an angle with the vertical axis of the knife.

FIG. 1 shows a knife, frontal projection; in fig. 2 - a knife with a reverse angle; in FIG. 3, the sectional area of the cut in the production thereof. a knife. according to the prototype and the proposed knife; in fig. 4 is a section A-A in FIG. 1 and 2.

The side wings 1 of the figured knife 2, made in the form of a figured bracket, are located at an angle pi to each other. They have sharpened side brackets 3, which form a reverse angle with the vertical axis of the knife, and together with the mating of the side wings 1 of knife 2, there is an ellipsoidal protrusion 4.

For robots, the knife is mounted on a device for the production of figured cuts on the grafted components of plants.

Due to the fact that the wings 1 of the figure knife 2 are located at an angle to each other, cutting of the grain of the wood over the entire cross section of the stem does not occur at a right angle and at the same time increases the area of the cut in the cross section of its cambial layer. FIG. 3 shows the area of the 5 slice on the prototype, and the area of the slice offered by the knife-b. Due to the elliptical protrusion 4 and the angle between the wings 1 of the knife 2, when connecting the drive with the stock, a high density of connection of the components, a large mechanical jipo4HocTb, is ensured. by preventing mechanical damage to the grafts, the contact area of the sole and submill layers increases, which improves grafting and increases the yield of grafts.

The proposed knife has a higher stability in the work in the production of cuts and serves a longer time due to the spatial configuration of its design. In addition, this allows the knife to be made of thinner tool steel, which reduces deformations in the cross section of the cutting section of the blade and the basement. The presence of the angle p between the side sharpened bevels of the wings of the knife ensures self-centering of grafting components along the axis of the knife.
