| 成果简介 | NOVELTY - The element has a main body made in a form of chain trains with a set of loosening elements (5), where the loosening elements are made in a form of pairs of mutually oppositely directed teeth that are conically sharpened on a side and connected to a plate (2) on another side by a detachable threaded connection (4). Two plates are rigidly fixed on outer opposite sides of links (1) of the chain train, made from flat rectangular strips and bent in a middle part along a short side at an obtuse angle. A set of bend holes are formed in two opposite sides through which the teeth are placed in a way that longitudinal axes of the teeth form an acute angle when the plates are rigidly fixed on the outer sides of the links at a bend. USE - Chain harrow working element for mulching a soil. ADVANTAGE - The element increases intensity of crushing crop residues to increase a depth of processing, thus ensuring better mixing with the soil, increased quality of soil mulching, preservation of soil moisture in dry periods and increase in yield of cultivated crops. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a chain harrow working element for mulching a soil. 1Links 2Plate 4Detachable threaded connection 5Loosening elements |
