Abstract

The invention relates to earth-moving equipment and, in particular, to the working equipment of a single-bucket excavator. The purpose of the invention is to increase the performance of an excavator by reducing the duration of its working cycle. The single-bucket excavator has a base chassis 1 with a driver's cab 2 and a turntable 3. On this platform, an arrow 4 is installed, carrying a handle 5 with a bucket 6. At the end of the handle 5, retractable hooks 12. are mounted. has supports 8, as well as lifting loops 9 and a sliding bottom 10 with a drive 11 rigidly attached to its upper part. The drive 11 is controlled from the driver's cab 2. The container 7 is installed on the ground next to the bottom, and with the help of the bucket 6 it is filled with the soil to be developed. Then, by means of retractable hooks 12, the handle 5 is coupled with the container 7 and is moved to the place of unloading. 1 il.

(57) The invention relates to a land-transport technique and, in particular, to the working equipment of a single-bucket excavator. The purpose of the invention is to increase the performance of an excavator by reducing the duration of its working cycle.

The single-bucket excavator has a base chassis 1 with a driver's cab 2 and a turntable 3. On this platform, an arrow 4 is installed, carrying a handle 5 with a bucket 6. At the end of the handle 5, retractable hooks 12 are mounted. The excavator is also equipped with an accumulative self-unloading capacity 7. It has supports 8, as well as lifting loops 9 and a sliding bottom 10 with a drive 11 rigidly attached to its upper part. The drive 11 is controlled from the driver's cab 2. The container 7 is installed on the ground next to the bottom and with the help of the bucket 6 it is filled with the developed soil.

The invention relates to a earth-moving machinery, in particular to the working equipment of a single-bucket excavator.

The purpose of the invention is to increase the performance of an excavator by reducing the duration of its working cycle.

The drawing shows an excavator, a general view.

The single-bucket excavator has a base chassis 1 with a cab 2 of the driver and with a turntable 3, on which. The boom 4 is fixed to the second, carrying the arm 5 with the bucket 6. In addition, the excavator is equipped with a storage self-unloading container 7, which has supports 8 for its installation on the ground, as well as lifting grips 9 rigidly attached to its upper part and sliding bottom 10 with the drive 11, controlled from driver's cab 2. Retractable hooks 12 are mounted at the end of the handle 5.

The excavator works as follows.

The soil (or other material) collected by the bucket 6 is poured into the container 7 installed next to the face of the ground. This process continues several times until the specified container is completely filled. Then the driver lowers the handle 5 into the area between the load gripping loops 9 and

There is an extension of the hooks 12 for engaging the container 7 with the handle 5. Thereafter, the driver lifts the container 7 and moves it to the place of discharge. In order to unload the tank 7, the driver turns on the drive 11 of the sliding bottom 10 and dumps the soil in the tank into a dump or into a vehicle. After that, the driver returns the sliding bottom 10 to the initial position and sets the container 7 to its former place near the bottom, unclipping it from the handle 5. Then the process is repeated.
