The invention relates to construction, amelioration and road engineering, and more specifically to the equipment of single-bucket excavators, designed to clean up the open channel of the ameliorative network from sediment and vegetation in the zones of drained and irrigated agriculture and is complementary to the main by autom. St. No. 1183617. The aim of the invention is to improve the reliability and quality of work, as well as to facilitate the control of equipment. FIG. 1 shows schematically the working equipment of a single-bucket excavator j in FIG. 2 is a view A of FIG. 1 ... The proposed working equipment of a single-bucket excavator consists of a handle 1 with a frame 2 placed on it, on which a bucket 3 is hingedly mounted with a cutting edge On the handle 1 a slider 4 is mounted with longitudinal movement, which is pivotally connected to the hydraulic control cylinder 5 and a lever 6, the second end of which is connected to the bucket 3. The lever 6 is telescopically completed with the ability to be adjusted in length with the holes 7 and a finger On the opposite side of the slide 4 on the cutting edge of the bucket 3, the bracket is installed Teyns 9, on which on the axis 10 are pivotally mounted the knife 11. The latter is spring-loaded by springs 12, which are fixed at one end on the slider 4, and the other on the knife 11. At the same time, the knife 11 with the bracket us 9 and the springs 12 are installed with the possibility of mixing with respect to the slider 4 by means of holes 13 and clamps 14. Handle 1 is connected with an excavator by a cable 15, which goes around the guide block 16. The working equipment of a single bucket excavator works as follows. The excavator is installed on the berm of the channel 17 opposite the place of work, but no closer than 0.5 m from its brow. Depending on the parameters of channel 17, its depth, width along the bottom and laying of slopes, the excavator adjusts the rehea angle of the bucket 3, setting it optimal for the given channel size 17. Adjusting the cutting angle is performed by the telescopic lever 6, which is either pulled out or pushed , fixing with a finger 8, into one of the holes 7. At the same time adjust the position of the knife 11 and the spring 12, which must correspond to a certain position of the telescopic lever 6, ensuring constant contact of the cutting edge of the bucket 3 when it closing the cutting edge of the blade 11. For this, depending on the controlled position of the lever 6 is lowered or raised an arm 9 with a knife t1 and spring 12, locking the latches 14 in their holes 13, and then begin the channel floor cleaning of pumps and vegetation. The handle 1 with the bucket 3 is lowered to the bottom of the channel 17, while the bucket 3 is in the extreme open position and the cutting knife 11 is in the extreme upper position. The cutting edge of the bucket 3 is cut into the pumps at the bottom of the channel 17 and separates them from the sole of the back end on the opposite side of the excavator. Then turn on the valve (not shown), feeding the oil into the piston cavity of the control hydraulic cylinder 5. The rod of the hydraulic cylinder 5 will begin to extend and act on the slider 4, which is lowered along the handle 1 downwards and turns the bucket 3 through the adjustable lever 6, producing a set of soil. At the same time, together with the lowering of the planer 4 and the rotation of the bucket 3, the knife 11 is lowered, which at its final lower point interacts with the cutting edge of the bucket 3, the closure of the latter. In this case, the cutting knife 11 cuts off the pumps with the channel 17 slope nearest to the excavator. In case a stone or another foreign object falls between the cutting edge of the bucket 3 and the knife 11, the knife 11 deviates into the inside of the bucket 3, turning around the axis 10, and after removing foreign objects in the process of unloading the bucket 3 of the spring 12 returns the knife 11 to its original position. The unloading of the bucket 3 occurs in fraternal order. Handle 1 with a cove 3 and accumulated soil raise about the bottom and out of the channel

17. Then, through the hydraulic distributor, the oil is fed into the rod cavity of the main hydraulic cylinder 5 of the control. The rod starts to pull in, raising the handle 1 of the slider 4, which through the adjustable 5 lever 6 turns the bucket 3 to the Open position, with it the knife 11 rises, takes the extreme

upper position - the bucket is unloaded.

After cleaning the bottom from one place of the station, the excavator moves to another place of the station, at a distance equal to the length of cleaning (about the width of the bucket) from one place of the station, taking into account the overlap, and the cycle repeats.
