To The Determination Of The Critical Circuit Speed Of The Sharing Drum, Kh. Kh. Igamberdiev, A.B. Mukhitdinov
Irrigation and Melioration
The article is devoted to the theoretical definition of the critical circumferential speed of the stripping drum of a kena harvester, which depends on the drum diameter, diameter and weight of the stems. It was determined from the equality of the change in the momentum of the stem during impact, i.e. from a shock impulse acting on the stem. The shock impulse is determined when the drum blade touches the stem in the process of stripping, which acts on the mass of the entire stem. The duration of the impact of the drum stripping on the stem was determined from …
An Innovative Seeder For Sowing Non-Loose Seeds Of Saxaul And Cherkez, E.T. Farmonov
An Innovative Seeder For Sowing Non-Loose Seeds Of Saxaul And Cherkez, E.T. Farmonov
Irrigation and Melioration
The main reasons for the absence of a seeder for mechanized sowing of non-loose seeds of fodder plants in deserts are analyzed in the article. The author has developed a technology for sowing non-loose seeds (saxaul and cherkez), which prevents clogging, crushing and breakage in the seeder hopper, and provides for uniform and stable sowing at a set rate and shallow depth over the entire field area without reducing the biological germination. An innovative seeder with a universal sowing unit is recommended. Field tests of the innovative seeder with the proposed universal sowing unit were conducted in February 2020, as …
