(54) LADDER BUCKET

 -. ...;

The invention relates to long-range planners intended for planning irrigated land.

The planner's working body is known, made in the form of a bucket with side walls, a rear wall, and a feather (with a cutting knife and a bottom made of telescopic plates 1J.

The disadvantage of this bucket is that the power consumption of the digging process is increased due to the interactions of the rear part of the bottom with the planned surface. Dsnshae loaded with soil creates a large edge with its back edge: a real pressure on the ground, which leads to the formation of a drag on the bottom and a decrease in the size of the discharge gap.

The closest technical solution to the proposed $ 1 is a planner bucket, including a back wall with a gliding knife, under the driver, side walls and bottom 12.

The disadvantage of this bucket is also a significant TsiroBoe force of high energy intensity when moving the soil and the uneven distribution of the drag force before the plankrukitsiim with a knife.

The purpose of the invention is to reduce the energy intensity of the planning process.

This is achieved by the fact that the bottom of the bucket is made of. fixed on the side walls by means of an elastic element and staggered across the entire length of the bucket horizontal platforms and from slalon platforms, each of which is pivotally mounted on the side walls - behind a corresponding horizontal platform, each horizontal platform having a vibrator mounted on it.

FIG. 1 shows the planner bucket, side view, in section; in fig. 2 section A-A in FIG. one; in fig. 3 - section B on fng. 1. The proposed planner bucket. Consists of a back wall 1 with a gliding knife 2, a scoring knife 3 and side walls 4 on which horizontal platforms are fixed by means of elastic elements 5 6. These platforms are located along the entire length of the bucket stepwise. To each of them, at an angle of repose of the processed soil in the hinge 7, inclined pads 8 are installed. Holes 9 in the side walls 4 serve to fix inclined pads with 8 fingers 1О. Horizontal 6 and inclined 8 platforms form a composite bottom of the scoop, and between them there is a gap for unloading the bucket. The hinge installation of inclined platforms provides a change in the angle of their installation and fixation with fingers 1O in one of the holes, depending on the physical condition of the soil of the planned floor. A magnetostrictive vibrator 11 is built into each of the horizontal pads. The cutting knife 3 is installed in front of the lower horizontal pad. Works scheduler bucket as follows. Move the working body along the line of planning. The cutting knife 3 cuts the ground and feeds it to the first horizontal platform, then to the inclined, next horizontal, etc. The planning knife 2, cutting the ground, feeds it to the back wall 1 in the form of a heap, distributed over which the soil fills the whole bucket capacity. The cut soil fills the depressions from the drag prism volume in front of the planning knife. The total mass of the soil is located on horizontal and inclined areas, which reduces the energy intensity of the process of moving the soil. In the case of drag prism, the ground is requested between inclined and horizontal platforms. A vibrator embedded in a horizontal platform contributes {to unloading the latter from the ground accumulated on it. The horizontal pads oscillate in the longitudinal direction when the field winding is turned on to the power source. Depending on the physical condition of the soil, the sloping platforms are set at a predetermined angle of repose. The distance between the horizontal platforms is less than the projection inclined on the horizontal axis. In the process of moving the bucket along the planning line, the cut soil fills the depressions from the volume of the drawing prism. At the same time, the bulk of the cut soil is located on horizontal platforms, which reduces the energy intensity of the planning process. By reducing the prism of the drawing ground, it is requested between inclined and horizontal platforms. The proposed bucket construction provides unloading of the prism in front of the blade, prevents self-compacting of the soil in the bucket and reduces the amount of thrust. Claim 1. A planner ladder comprising a back wall with a gliding knife, a scoring knife, side walls and bottom, characterized in that, in order to reduce the energy intensity of the leveling process, the bottom is made of fixed on the side walls by means of elastic elements and arranged stepwise along the entire length bucket of horizontal platforms and from inclined platforms, each of which is pivotally mounted on the side walls behind a corresponding horizontal platform. 2. Kovsh according to claim 1, of which is that each horizontal platform has a vibrator mounted on it. Sources of information taken into account during the examination 1.
