Description

The invention relates to earthmoving machines, namely, buckets, used primarily for digging narrow and deep trenches under a clay suspension by the method of walls in the ground.

The aim of the invention is to improve the performance of the bucket.

Figure 1 shows the excavator bucket in the position of raising the soil; figure 2 - the same, in the unloading position of the soil.

The bucket is formed by side 1 and rear 2 walls. In the latter, a window 3 is made. The bucket has front and rear ears 4 and 5 for attaching a backspit to the rod (not shown, the curator is mounted on an excavator designed to dig trenches.

The bucket has a cutting part 6, on which the tooth 7 is mounted. Along the perimeter of the bucket cross-section, the edges 8 of the grille 9 are secured from the links of the ring chain. The middle part 10 of the grid 9 is inserted into the window 3, and the grid itself is attached to the inner surface of Wall 1 and 2, adjacent to it. The end of the cable 11, the other horse of which is attached on the outer side of the bucket walls at point 12, is attached to the lattice section 9 entered in the windows 3. The length of the cable 11 is chosen equal to the distance from point 12 to window 3, and point 12 is located from window 3 on distance 1-1j5 from the maximum linear dimensions of the cross section of the window 3.

 The measures of the grid 9 are chosen in such a way that, when a part of the grid 10 of the grid 9 is tensioned by the action of the ground (Figure 1), the window leaves the window for a length of

5 О, 5-1,5 maximum linear dimensions of the window 3.

The digging process is carried out by an excavator with cable winches that, through blocks, exert an impact on the rod and backhook levers holding the bucket. The corresponding movements of the backhoe are lowered to the bottom of a trench filled with mud and

15 scoops up the next portion of soil. In this case, the tooth 7 loosens the ground. A bucket filled with soil is lifted through the clay slurry, which passes through the window 3 and the grid 9,

20 retention soil. In this case, the grille 9 is located outside the window 3, its area exceeds the area of the occ. 2-3 times, that when set-. Noah's area of the window allows you to accelerate the clay suspension from the ladle. When unloading the soil, the grid part 10 enters the bucket and is held by the cable 11. In this case, the grid 9 is separated from the inner walls of the carpet, which promotes the separation of the soil from the walls of the bucket and the grid by shaking and colliding the links.

The grille 9 does not obstruct the window, which facilitates the clay suspension coming out of the bucket, and the soil adhering to the walls of the bucket is cleared when the bucket is moved.

Claims (1)

EXCAVATOR BUCKET, including a housing with a loading window, containing a bottom with a cutting edge, side walls and a rear wall with a window for discharging clay slurry, which is covered by a lattice of ring chain links, characterized in that, in order to increase productivity, the lattice is made in the form lined on the inner sides of the walls and the bottom of the shell, which is attached to the housing along the perimeter of the loading window and adjacent to the rear wall, is connected by a cable passed through the window in the latter from the outside Noah case. . 1232749
