Description

one

The invention relates to the construction and can be used in laying a mole-draining ameliorative or irrigation purpose.

Known working body of the mole, including the knife and attached to it a draining unit with a spade tip, in the hollow chamber of which a magnetostrictive vibrator is attached to the front end wall.

The purpose of the invention is to reduce traction resistance.

For this purpose, in the proposed working body, the front end wall of the hollow chamber of the draineer is connected to its side tip via a rod waveguide, with an additional tubular type die head connected to an additional annular magnetostrictive vibrator using an additional tube type waveguide.

The drawing shows the proposed working body of the mole in the cut.

The working body of the spinner includes a knife 1 and a draining unit 2 attached to it with a die 3, in a hollow chamber 4 of which a magnetostrictive vibrator 5 in the form of a rod with an excitation winding is attached to the front end wall. To make resonance easier

The front wall of the hollow chamber 4 of the draener is connected to its striker tip 3 with a rod waveguide hub b, the natural frequency of which corresponds to the natural frequency of the magnetostrictive vibrator 5 and the frequency of the alternating current exciting the vibrator 5. To increase the oscillation power concentrically to the boyic tip 3 an additional striker tip 7 is installed a tubular type associated with an additional annular magnetostrictive vibrator 8 with an additional tubular type waveguide concentrator 9. Magnetostriction vibrators 5 and 8 are attached to the front end walls. Chamber 10 is associated with an additional die tip 7.

The working body works as follows.

When introducing a drener 2 into the ground, the oscillator is turned on and the excitation windings of the vibrators 5 and 8 are occupied, resulting in the electromagnetic oscillations being converted into elastic high-frequency vibrations of the vibrator rod 5 and the vibrator rings 8. From the vibrators 5 and 8, the oscillations are transmitted to the waveguide concentrators 6 and 9, which amplify the signals and create resonant modes of oscillations in the out-of-ground wave at the die tips 3 and 7. As a result

Vibration of bonded tips reduces traction co-motivation to the introduction of a mole of the working body into the ground.

Subject invention

The working body of the mole that includes

knife and attached to it drayner with a die head, in a hollow chamber which

to the front end wall is a cryptographic magnetostriction vibrator, due to the fact that, in order to reduce traction resistance, the front end wall of the hollow draining chamber is connected with its Boykovka packer core rod waveguide, and the striker tip is equipped with a concentric It is provided with an additional die tip of a tubular tube with an annular magnetostrictive vibrator, which are interconnected by an additional waveguide of the tubular tin.
