The paper discusses the problems of plant protection from weeds and need to improve methods weed control in production agricultural products, describes used. design an improved fire cultivator for burning gardens vineyards by thermal method, as well technological process its operation, is presented.
Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) model presented by Michalakopoulos and Panagiotou is developed to determine an optimal truc...
Aiming at the common problems of high working resistance, low soil disturbance, and rates missed extraction in operation carrot combine harvesters, a high-efficiency drag-reducing bionic soil-loosening shovel was designed this study. The physical parameters carrots were measured, using badger claw toe as prototype. wing structures designed. Based on EDEM discrete element simulation technology, ...
The depth of tillage and its uniformity are the main performance indicators chisel cultivators, as well all machines. Only when these at level demand, favorable conditions created for uniform development ripening crops throughout field their high yield. article theoretically explores problem ensuring a smooth movement suspension cultivator along with working depth. results show that given requi...
Weeds compete with crops for water, nutrients, and light consequently, have adverse effects on the crop yield overall productivity. Mechanical weeding is most common non-chemical method weed control, which applied in organic farming, cultivator implement mechanical weeding. This study aimed to design develop an innovative active tool optimize cultivation depth, can avoid damage roots improve ke...
Cement plants in the central Hudson River valley utilize limestones of the Helderbergian Series of the Lower Devonian. Chiefly calcilutites, calcarenites, and cherty calcisiltites, these rocks represent progressively deeper environments, from lagoonal to neritic, with scattered reef deposits. Stratigraphic continuity is marked, and a layer-bylayer analysis shows strikingly constant chemical com...
