Description

Devices for controlling the operation of a bulldozer at a given cutting angle are already known.

A distinctive feature of the proposed device, which distinguishes it from the known devices of this kind, is that in order to be able to adjust the position of the blade directly from the bulldoz’s cabin;) specified angle of cutting, and to indicate the angle of inclination of the base of the bulldozer, between them a lever in the form of a tandem, i.e., its double-sided arrow, placed in a transparent vessel filled with viscous liquid, was placed. For direct observation of the blade cutting angle, on the pushing bar, at a right angle to it, a bracket with an arrow moving at the scale, placed in the bulldozer cabin, is fixed.

Such an embodiment of the device eliminates the need to stop the machine in order to verify the correctness of the processing of this area, using external landmarks, and increases the accuracy of the earthworks to be performed.

The drawing shows schematically the described device.

The device consists of a plumb bob (tambourine) 1, index arrows 2 and 3 that are horizontally attached to it, fixed fixed plichkah 4 and the same moving arms 5. The scales are fixed on racks 5 and 7, which are mounted on the frame of the bulldozer 8. The measurement in degrees of the angle of inclination of the pushing bar 9 of the bulldozer to the horizon is carried out with the aid of a bracket 10 connected with the pushing bar 9 and the index arrow //, against which the angle gauge 12 is located.

The Y's tangent with arrows 2 and 5 is highlighted on the mobile IJ axis. In order to eliminate vibrations of the tambourine from vibrations - and shocks of the bulldozer, the mother (plumb) and arrows are placed in a closed transparent vessel filled with glycerin.

Subject invented l

The device for controlling the position of the blade of the bulldozer during its operation with a predetermined angle of the cut-and, characterized in that, in order to ensure the possibility of adjusting the position of the blade directly from the cab, it is mounted "o. In. The last in-ide graded reinforced in the frame of the bulldozer and the achieved cutting angle is fixed on it, secondly installed with the possibility of its movement for fixing the specified angle of cutting, and to show the angle of inclination of the base of the bulldozer, between them is mounted a lever in the form of a Matnik, a double-sided arrow placed in a vessel filled with a viscous liquid, such as glycerin, and to directly aggravate the angle of the blade cut, on the pushing bar, at right angles to it, a bracket is fixed with an arrow that is not at the graduated scale placed in the cab bulldozer.
