Experimental research of para­meters of work of top-gathering machine for continuous cut of tops of vegetable

Abstract

The purpose. Experimental determination of rational parameters of cutting tops of vegetable by the developed unit for maintenance of necessary quality of cleaning tops of vegetable. Methods. Rational machine-using in plant growing, experimental researches and field tests of agricultural machines, estimation of parameters of quality of work. Results. Field experimental researches were carried out of frontally hung on wheel tilling tractor of new top-gathering machine intended for continuous non-sensing cut of green mass of tops of vegetable of sugar beet. Thus, new laboratory-field apparatus was developed which consisted from frontally hung top-gathering machine of rotor type with horizontal axis of rotation, cross-section screw for gathering the cut off tops of vegetable, loading mechanism in the form of paddle blower, and loading branch pipe. On the prepared plot of crops of sugar beet they cut off mass of tops of vegetable at various parameters of technological process of cleaning which then estimated by amount of tops of vegetable which remained on heads of root crops and in row width of crops (non-cut off rests of tops of vegetable). Conclusions. Under the developed program and technique they carried out statistical processing of results of experimental researches by means of personal computer. It allowed to receive graphic dependences of the specified rests of tops of vegetable on heads of root crops that helped to determine parameters of work of new top-gathering machine for continuous cut of tops of vegetable of sugar beet. The established dependences enabled to choose rational constructive and technological parameters of harvesting tops of vegetable of frontally hung top-gathering machine.
