On both sides of the reflector 5 there are installed openers 7 that copy the channel profile. Depending on the design of the hitch, the working body can be mounted both behind the tractor and on the side.

Прокладка канала осуществляется следующим образом. 25Laying the channel as follows. 25

От вала отбора мощности трактора через механический привод вращение передается на конуса 1 через ступицу 2.From the tractor power take-off shaft through a mechanical drive, rotation is transmitted to the cone 1 through the hub 2.

В процессе вращения’’режущие эле- ₃₀менты 4 срезают из забоя грунт, который, попадая на лопасти 3, транспортируется в зону разгрузки. Под воздействием сил инерции грунт выбрасывается из забоя и попадает на двухсторонний отражатель 5, который отбрасывает его на расстояние до 15 м от бермы канала. Дно канала приглаживается ползуном 6.During vrascheniya''rezhuschie element ₃₀ cops 4 is cut from the bottom of the soil, which, coming into contact with the blade 3, is transported to the unloading zone. Under the influence of inertia, the soil is ejected from the face and falls on a double-sided reflector 5, which casts it to a distance of 15 m from the channel berm. The bottom of the channel is smoothed by the slider 6.

Открылки 7, копирующие профиль отрываемого канала, исключают попадание отдельных кубков грунта и крошки.Postcards 7, copying the profile of the torn channel, exclude the ingress of individual soil cups and crumbs.

Предлагаемая конструкция позволяет более эффективно подготовить грунт к выбросу из забоя за счет того, что вся срезаемая стружка направляется и скапливается на плос-. костях лопастей 3 к моменту выброса из забоямThe proposed design allows you to more effectively prepare the soil for ejection from the bottom due to the fact that all cut chips are directed and accumulated flat. the bones of the blades 3 at the time of ejection from the faces
