Description

A machine for formation in the ground for the purpose of draining its narrow trenches, having a working body in the form of an endless chain, laying, moving elements and choosing soil, is known for it. Due to the fact that the working elements of these devices were made in the form of scrapers, the walls of the trench did not turn out to be sufficiently smooth and such machines were unsuitable for work in stony soil or in the soil with tree roots.

In order to create a more versatile working body, it is proposed to install on such an endless chain in alternate order blade blades and blade blades, and in these blades the cutting edges of the blades and knives protrude above the edges of the blades, thereby achieving the possibility of cutting through a narrow trench even in a stumpy ground.

In addition, in order to close the trench with a layer of soil with a turf and form a drain cavity, removable equipment is installed behind the endless chain, consisting of a disc knife, a roller and a polozok with spring-loaded blades, and for an open trench, for an endless chain instead of a circular knife, and the skid is installed a shield serving to divert to the ground, taken out with an endless chain.

FIG. 1 is a side view of a trencher; FIG. 2 - its working bodies; FIG. 3 - additional removable equipment for closing the trench with a layer of turf; FIG. 4 - a section through the closed trench; Fig-5 - removable equipment, a shield for removal to the ground; FIG. 6 - view of the shield from above.

The transomonetor (FIG. 1) is an attachment to a caterpillar tractor and consists of an endless chain / spanning frame 4, main frame 5, drive shaft 6, gearbox 7, boom 9, winch 11, and hopper 8.

The endless chain receives rotation from the tractor's weaning shaft through shaft 6 and gearbox 7. Chain frame 4 can be rotated

around the axis of the upper sprocket. The turn is carried out with the help of a winch // and a polyspast 8, fixed on the arrow 9 and t 10, pivotally attached to the frame 4. In the raised position, the chain takes the position shown in FIG. 1 by a dashed line, and in this form the trencher moves to a new location.

On an endless chain, shovels 2 and blade knives 3 are fixed in alternating order (Fig. 2). The cutting edges of the knives in the blades 3 protrude above the edges of the blade itself, which contributes to the creation of smoother trench walls and ensures the cutting of wood residues that may occur in the soil.

Driving with a chain with such working bodies cuts a trench in the ground up to a depth of 2 m and a width of 120 mm.

If the trench is used to create a closed drain, then additional equipment is mounted behind the endless chain, consisting (fig. 3) of a polo 3, a roll 5 consisting of two cylinders of different diameters, and a disk knife 6 mounted on a common frame 7.

The blade disk 6 is inclined to the side (Fig. 4) and serves to cut the edge of the turf in the upper part of the trench. The cut edge of the turf in the form of a triangular cross-section (see Figs. 3 and 4) is pressed into the trench of the rear-facing roll 5. At the same time, the slider 3 running into the trench limits the depth of the turf lowering, and the two knives installed in the upper part of the slider trenches are two excavations that serve to secure the formation in the trench at a predetermined depth.

The height of the track 3 can be adjusted by shifting it in the holes of the rack 2 of the frame.

The knives / are seated on the sled, on the hinge and may deviate (against the action of the spring) when meeting with a stump or other obstacle in the ground.

Instead of a roller for pressing in the trench of the cut turf, a slider 4 can be installed (FIG. 3).

In case the trench is used for laying drainage pipes in it, then other removable equipment is used, consisting (Fig. 5 and 6) of a flat shield 2 with a knife / mounted on the boom 9 using extensions 3 to 4.

The shield and knife are located at an angle to the plane of rotation of the chain and serve to divert sideways the soil taken out by the working elements of the chain.

Soil thrown out at high speed by an endless chain hits the shield i and drops to the side. Soil that has fallen close to the trench is moved away from it with a knife / shield.
