Device for cutting mole-drains

FIELD: agriculture.

SUBSTANCE: device comprises a vertical blade 1 with two wings 2 having cutting edges and cartridges 3. The vertical blade is equipped with an additional cartridge 4, firmly fixed in the base of the blade 1. The cartridges are made in the form of the cylinders truncated in front part with bevels directed upwards, and are rigidly fixed to the wings.

The invention relates to agriculture and can be used for cutting mole drainage on besuconas areas mainly in the draining wetlands, implementation of leaching heavy saline soils, subsoil irrigation and lowering of the groundwater level.

Known working body chromogranine machines, including vertical knife with two D-shaped wings and greenery attached to the wings by means of bent upwards and parallel edges [SU, A.S. No. 698565, CL AV 13/00, EV 11/02].

A disadvantage of the known device is that when cutting drains on besuconas areas, raising groundwater contributes to the rapid flooding and dislodging of molehills.

A device for cutting of molehills, including vertical knife with two wings, having cutting edges and greenery made in the form of truncated in front of the cylinders, installed slanted to the center and rigidly connected with wings, made in the form of plates C-shaped cantilever rounded areas which have the General form with cylinders trenerov [SU, A.S. No. 1751263 A1, CL EV 11/00, the prototype].

A disadvantage of the known device is that when cutting of molehills plate-shaped destroy the soil structure and along with the improvement of aeration mode red eye reduction) what is the density of the drain space and sustainability drains to silting. When cutting on besuconas areas such molehills are also beginning to salivate and creep after irrigation or raise groundwater levels.

The technical result is to increase the resistance to sedimentation and erosion mole drains, cut mainly in the area without design slope, lowering of groundwater level.

The technical result is achieved in that the cutting device of molehills included vertical knife with two wings, having cutting edges and greenery made in the form of truncated in front of the cylinder with bevels and rigidly fixed with wings, according to the invention the vertical knife features an additional grenera rigidly mounted in the base of the knife bevels trenerov directed upwards, and the wings of crotonates installed symmetrically to the vertical axis of the knife and directed upwards relative to the horizontal axis of the knife at an angle γ=12°-35°.

The invention is illustrated figure 1 - General view, figure 2 - General view with the indicated angle γ.

The device consists of a vertical knife 1, rigidly fixed at the base of the knife 1 additional grenera 4, the main trenerov 3, wings with 2 cutting edges, installed symmetrically to the vertical axis of the knife 1, upward relative to the horizontal axis of the knife 1 at an angle γ=12°-35°, and rigidly zakreplena the main tenerani 3 and additional grenera 4. All dreary made in the form of a truncated in front of the cylinder with the bevel up.

The device operates as follows.

When cutting mole drainage in the soil simultaneously formed three mole drains in two tiers, with an additional 4 below basic 3 and is more tightly folded lower soil layers. Basic mole drains 3 remain connected with additional passage 4, left cutting edges of the wings 2. Water does not completely fill the main mole drains 3, and flows into the additional 4, thereby decreasing the process of silting. Additional drena 4 delays the rising groundwater in the core 3 and also increases the life of molehills. Different levels of pledging additional and main drains gives the possibility to use the device in areas without project draft water does not stagnate in the main mole drains 3, and the channel left by the cutting edges of the wings 2, is adjudged to be in an additional drain 4.

The use of the invention in agriculture improves water and air regimes of soils, accelerating runoff, decreased groundwater levels, can be used in areas without project draft speeds up the process of desalinization heavy soils under leaching. The proposed construction of a soybean is inane three trenerov in different levels ensures a long and reliable operation of mole drainage.

The cutting device of molehills, including vertical knife with two wings, having cutting edges and greenery made in the form of truncated in front of the cylinder with bevels and rigidly fixed with wings, characterized in that the vertical knife features an additional grenera rigidly mounted in the base of the knife bevels trenerov directed upwards, and the wings of crotonates installed symmetrically to the vertical axis of the knife and directed upwards relative to the horizontal axis of the knife at an angle γ=12°-35°.
