RU2792778C2 - Rotating auger for planting seedlings on film coating - Google Patents

Abstract

FIELD: agriculture; gardening.

SUBSTANCE: rotating auger contains a bearing pipe, on a lower part of which an auger is installed, and to an upper end an auger rotation handle is attached. The auger is made two-input, to a lower end of the bearing pipe an upper end of a guiding rod of a circular cross-section is attached, a lower end of the rod is sharpened to a cone, an axis of the rod coincides with an axis of the auger. Between outer ends of cutting edges of the auger and upper points of lower semi-turns of the auger, 2 knives are installed for cutting roots, cutting edges of knives are parallel to the axis of the auger, and a connection of the bearing pipe to the auger rotation handle is made with a pipeline tee.

EFFECT: improvement of weed suppression and creation of more favorable conditions for plant growth.

Description

The invention relates to the field of agriculture and can be applied in horticulture.

There are advertisements on the Internet for many types of garden augers. But these drills are not suitable for planting seedlings on a film cover, since they cannot keep the coincidence of the axes of the drill and the well during the drilling process and do not cut off the roots of plants. The roots are wound on the auger, destroy the walls of the well and shift the axis of the drill from a given direction.

The closest in terms of the totality of features is the auger earthen drill designed by Zemlyakov N.V. (RF patent No. 2236546), but it has the same defects.

Before planting seedlings on the film cover at the planting points, cross cuts are made equal to the diameter of the auger. The problem to which this invention is directed is to prevent the increase in the size of these cuts when drilling landing wells.

The technical result that can be obtained by its implementation is to improve the suppression of weeds and to create more favorable conditions for plant growth.

The technical result is achieved by the fact that to the auger drill, containing a carrier pipe on the lower part of which an auger is installed, and a handle for rotating the drill rotation is attached to the upper end, a round-section guide rod, knives for cutting roots and a pipeline tee are added, and the auger is made double-threaded.

In FIG. 1 shows a general view of the device.

The device consists of a carrier pipe 1 to the upper end of which a drill rotation handle 2 is connected by a pipeline tee 3. A two-way auger 4 is installed on the lower part of the carrier pipe, and the upper end of the guide rod 5 is attached to the lower end of the pipe 1. The rod has a circular cross section. The axis of the rod coincides with the axis of the drill. The lower end of the rod is sharpened into a cone. The lock nut 6 provides rigid fastening of the rod 5 to the pipe 1. Between the outer ends of the cutting edges of the auger 7 and the upper points of the lower half-turns of the auger, 2 knives for cutting the roots 8 are installed. The cutting edges of the knives are parallel to the axis of the drill. The knives are attached to the auger at 9 points.

In FIG. 2 shows the shape of the knives 8. The dotted lines show the welds.

The device works as follows. Before drilling the well, the sharp end of the rod 5 is set to the center of the cross section. Then the sectors of the cut are filled under the coating, the rod and the ends of the knives protruding downwards 8 are pressed into the ground. After that, the well is drilled in the usual way.

Water is poured into planting wells 25-30 cm deep, then they are filled with compost or other nutrient composition and seedlings are planted. Looser and more nutritious soil inside the well creates conditions for the growth of roots in the depth of the well and reduces competition between neighboring plants.

Approximate dimensions of the drill parts when the operator is working in a sitting position: pipe diameter 1-20 mm, length - 400 mm, auger diameter - 84 mm, rod diameter 5-6 mm, length - 140 mm.

The height of the drill can be increased by a piece of pipe with a diameter of 20 mm with threaded ends and a pipeline coupling. Such a drill can drill holes for metal supports for trellises and fences.
