SU30005A1 - Device for mole drainage - Google Patents

Description

The MAIN copyright certificate No. 29653 describes a device for immersing a track, wire, etc. into the soil when carrying mole drains, consisting of a saw, equipped with a coil with a rope and ears for guiding the latter when winding it during the action of the saw.

The first one, which is dependent on the main author's certificate No. 29654, proposes a new form of implementation of this device, with the aim of mechanizing the work of immersing the cable, which is greatly facilitated and accelerated due to the replacement of the manual immersion method. To achieve this goal, an accessory device is introduced in the form of a quukh. wheels with wide rims on the axle, to which a curved double arm is attached, one shoulder of which is riveted to the saw, while the other ends with a handle designed to act on KQQ. the power of a worker to vibrate the saw cutting the soil.

The modification described below represents a further improvement of the fixtures described in the aforementioned copyright certificates, and that the rear end of the frame with a knife rests on an ellipsoidal roller, which is free-rotating, resting on the soil, and the frame on that the end is provided with a weight for lowering it.

The drawing shows a general schematic view of the device for mole drainage.

A steel knife /, vertically lowered into the soil, poi, in its forward motion, winds 2 cable 3 from the coil, passed through the earpieces placed on the rear side of the knife. Cable 3 remains in the soil. The knife is supported in front by a pair of wheels with a hook 8 for coupling with the winch rope and behind the ellipsoidal roller with spurs located on rack 5. Load 7 is suspended at the end of the frame bent upwards. During operation the winch is not all

device for the hook 8. The knife cuts and cuts the soil, periodically lowering and raising, due to the swings of the rear part of the frame, in the vertical direction, when the ellipsoidal roller moves on rough ground. Load 7 is so designed that when lowering the back of the frame presses the knife into the soil. The depth of the cable 3 can be set by changing the position of the knife screws, not shown in the drawing.

The subject matter of the invention.

Modification of the accessories described in copyright certificates No. 29653 and 29654, in order to vibrate the saw, the rear end of the frame with the knife rests on a freely rotating, ground-supported roller 4 of ellipsoidal shape, and the frame at the same end is its lowering is equipped with a load of 7.
