Bir cho‘michli ekskavatorning uzatish mexanizmining bir qismi bo‘lgan asosiy mexanizmlari (ko‘tarish va bosim mexanizmlari) va bosim mexanizmlari sezilarli darajada o‘zgaradi, bir cho‘michli ekskavatorning ishlaydigan qurilmalari mexanizmlarini birgalikda ishlatish jarayonida ko‘tarish va bosim elektr yuritmalarining ish rejimlari tahlil qilingan. Tahlil jarayonida qazish vaqtida rejim parametrlarining o‘zgarishi, cho‘michning harakatiga qarshilik kuchlarining ortishi bilan ham bog‘liq (tog‘ jinsining og‘irlik kuchi, cho‘michga kirish ishqalanish kuchi) va ishchi uskuna mexanizmining bo‘g‘inlarining nisbiy holatini va shunga mos ravishda kuchlarning yelkalarini o‘zgartirish orqali amalga oshiriladi. Tahlil qilish natijasida energiyaquvvat parametrlarini cho‘michning tog‘ jinsini kesish tomonida amalga oshirishda asosiy mexanizmlarning yuritmalari o‘rtasidagi o‘zaro ta’sir darajasini tahlil qilish moslashuvchan va o‘z-o‘zidan sozlanadigan ish oqimini boshqarish tizimini asoslash imkonini beradi.

The main mechanisms (lifting and pressure) and pressure mechanisms that are part of the transmission mechanism of a rotary excavator change significantly. As shown, the change in the mode parameters during excavation is also associated with an increase in the forces of resistance to the movement of the bucket (rock gravity, friction force entering the bucket) and the relative position of the hinges of the working equipment. mechanism and is carried out by changing the shoulders of forces, respectively. As a result of the analysis, the level of interaction between the actions of the main mechanisms in the implementation of energy-power parameters on the rock-cutting side of the bucket makes it possible to justify a flexible and self-adjusting workflow control system.
