Abstract

This invention relates to agriculture. The aim of the invention is to reduce the possibility of damage to the root tube and increase productivity. Blade 2 has sharpened front edges 3 and side edges 4. Along the symmetry axis of the blade 2, there is a longitudinal groove formed by the side edges 5 and the rear edge 6. The latter is folded up above the surface of the blade 2. The side edges 5 are bent down and made in the form of vertical wedge-shaped knives forms with an acute angle α at the top, and sharpened along the entire length. The ratio of the length of the longitudinal groove to the length of the blade is 0.6-0.7: 1, the width of the groove to the width of the blade 0.3-0.4: 1, and the angle at the apex of the wedge-shaped knives is 8 - 12 °. During operation, the shovel advances a longitudinal groove on the boom and with its foot it sinks into the soil. The presence of sharpened edges 4, vertical wedge-shaped knives provide cutting of the roots with a slip. When the shovel is dredged, the concave shape of the blade 2 allows for the removal of soil and cut roots. 1 hp ff, 4 ill.

FIELD OF THE INVENTION The invention relates to agriculture, in particular, to hand tools for the cooking of grapes. The aim of the invention is to reduce the possibility of damage to the root tube and increase productivity.

FIG. 1 depicts the proposed shovel, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 is a diagram of the installation of a shovel to the plane of the trellis when processing the prishtambovy zone, top view.

A grape-vest shovel consists of a stalk with a holder 1 and a concave blade 2. Blade 2 has sharpened front edges 3 and parallel lateral edges 4. Along the symmetry axis of the blade 2, there is a longitudinal groove from the front edge side formed by the lateral edges 5 and the rear edge 6 , bent up above the surface of the blade 2. The side edges 5 are bent down and made in the form of vertical wedge-shaped knives with an acute angle cx at the apex and have a sharpening along the entire length. The ratio of the length of the longitudinal groove to the length of the blade 2 is 0.60-0.70; 1, the width of the groove to the blade pyrine 2, 0.30-0.40: 1, and the presence of bent edges 6 and 5 of the groove required blade stiffness 2. Execution angle a. at the apex of the wedge-shaped knives equal to 8-12 °, the spade easily penetrates the soil and the slip of the neck, cutting the surface roots.

Work with a shovel is performed as follows.

The shovel advances with a longitudinal groove opened on the stem and extends into the soil with a foot. The presence of sharpened side edges 4 of the blade 2 and wedge-shaped vertical knives ensures a high-quality cutting with sliding of the surface roots in the zone of burial.

When the shovel is dredged, the concave shape of the blade 2 allows the soil and the cut roots to be removed from the root zone of the cultivated area.

Since during the deepening and deepening of the blade 2, the bent side edges 5 of the longitudinal groove move along the crust, non-shtambal, the contact of the cutting faces with the tapered is prevented and the possibility of its damage is reduced.

In addition, the two-sided coverage of the shovel with the blade of the shovel makes it possible to treat the pristambovy area half the width of the blade of the shovel, which is located

just one side of the tweezers that

reduces the amount of soil carried out from the zone of the shtamba and eliminates the need for a circular bypass of the trunk,

As a result of the use of the proposed 5 shovels, the possibility of damaging the grape grass kornestamba is reduced, the yTOMviHeMOCTb worker is reduced, and labor productivity increases.

Claims (2)

1. Shovel for cropping grape plants, including a stem with a holder, a blade with cutting front and side edges, while on the blade along the axis 5 symmetry from the side of the front face, a longitudinal groove is formed, which forms the inner rear and side cutting edges, characterized in that, in order to reduce the possibility of damage to the root socket and increase productivity, the blade 0 is concave, the rear and side cutting edges are bent under the straight yrvioM to the surface formed by the bases of the internal rear and side cutting edges, in opposite directions, the rear edge is bent upwards relative to the front side of the blade, and the side edges are made in the form of knives wedge-shaped with ives ins on the front edges. Q 2. The shovel according to claim 1, characterized in that the ratio of the groove length to the blade length is 0.60-0.70: 1 the width of the groove, to the blade width 0.30-0.40: 1, the angle at the apex of the wedge-shaped knives is 8-12 °.
