Description

The device relates to forestry and can be used in the arrangement of fire strips.

A number of technical solutions are known that were identified as a result of patent research and taken into account by the applicant in the analysis, namely: A.S. 112005, RU 2231241, 2086083, 208093, 2083067, 1753965, 1695836, 1547726, 1457828, 535040, 408489, 390785, 2204225, 2177213, 2102846, 2102844, 2091997, 2088061, 2086083, 2060621, 1792233.

The closest technical solution adopted by the applicant as a prototype is a tillage implement containing a frame in the form of bars with teeth fixed to them, a drive (AS No. 600975, publ. 05.0.1978).

The disadvantage of this device is that it requires a traction machine.

The technical task of the claimed utility model is to provide soil tillage when the device is moving without a special tractor.

A design feature is that the soil is treated with working bodies in a rotary-vibrational mode.

The use of the rotary-vibrational mode of operation in comparison with rotation allows the use of elastic strain energy. In this case, we use the oscillations of gyroscopes, and we get a two-stage oscillatory system consisting of the natural oscillations of two systems at the same partial frequencies: the first system is the oscillations of a two-stage gyroscope, the second system is a physical pendulum, which characterizes the physically strong interaction of the two systems at resonance. The highlight of the project is the coincidence of partial frequencies to create resonance. With this small force we create oscillations of the working tool with a large amplitude.

The creation of oscillations along the axis of the device using unbalance will ensure the emergence of the "Zhukovsky effect." It consists in creating perpendicular to the movement of the device oscillations of the working body.

The theoretical background of the device is given in the following sources:

- Bulgakov B.V. Applied Theory of Gyroscopes;

- Strelkov V.P. Introduction to the theory of oscillations;

- Scarborough, James Blaine. Gyroscope. Theory and application;

- Danilin V.P. Gyroscopic instruments;

- Gulia N.V. Inertia;

- Ass B.A. Assembly, adjustment and testing of aviation devices.

In FIG. 1 shows the inventive device in its initial position, FIG. 2 shows the device at time t, when the teeth of the device are deepened with a right roll.

The device contains teeth 1 mounted on a beam made of two torsion bars 2 and 3 arranged coaxially. A spinal frame 4 is installed perpendicular to the beam, equipped with guide wheels 5, 6 on both sides. A housing 7 is mounted on the spinal frame, and an unbalance is installed in the upper part of the beam 8 with motor to create impedance. Gyroscopes 9 and 10 with engines are installed along the edges of the beam.

Initially, gyroscopes 9 and 10 are started using engines (for example, gasoline) in opposite directions. Then the unbalance engine 8 is started. When the spinal frame 4 rolls with teeth, the pitch moment occurs due to the gyroscopes 9 10, and due to the rotation of the gyroscope rotors in opposite directions, when the teeth are buried into the ground, the teeth twist out of the ground and translational reaction moves. So, with the left roll, the left pitchfork is dipped and the right pitchfork is dived and vice versa, while the teeth 1 located on the torsion bars 2 and 3 turn the earth out and the device moves forward.

Example of device calculation:

1. The mass of the device is 600 kg;

2. The mass of one rotor of the gyroscope is 30 kg;

3. The engine power of the gyro rotor is 5 hp, the rotor speed is 3000 rpm;

4. The length of the spinal beam - 2 m;

5. The length of the beam with teeth - 2 m;

6. The number of revolutions of the unbalance engine is 80 rpm;

7. Depth of plowing - 15 cm;

8. The plowing speed of 1.5 km \ hour;

9. Plowing width 2 m;

10. The vibrational energy of 37 kJ;

11. The moment of inertia of one rotor is 0.2 kg / m ² .

12. The force (moment) during soil eversion - 420 kgm, the number of vibrations in sec - 1.3;

13. The total drive power of 15 hp

Thus, the claimed utility model, making oscillatory movements, produces inclinations relative to the spinal beam, while the soil is inverted, and the device moves progressively, thereby creating a fire band.
