JUSTIFICATION OF THE ANGLE OF INSTALLATION AND THE LENGTH OF THE COMB

ON THE COMBING DRUM WHEN HARVESTING SOYBEANS

Vladimir A. Sakharov, Alexey A. Kuvshinov

All-Russian Scientific Research Institute of Soybean, Blagoveshchensk, Russia, kyaa@vniisoi.ru

Abstract. Harvesting is an important and energy-intensive operation in agricultural production.

Currently, the improvement of the harvesting process is associated with the development of precise

positioning systems, computer systems, and increased reliability of components and assemblies. An

important problem of soybean harvesting is the reduction of energy intensity, the solution of which is

possible with the approbation and implementation of the method of combing plants on the root. In this

paper, the geometric parameters of the comb of the combing drum for harvesting soybeans are investigated,

the design dimensions of the comb of the combing drum are theoretically justified. Analyzing the presented

results, it was found out that the maximum possible angle of installation of combing combs relative to the

radius of the drum is 50�. In this case, the length of the comb tooth should not exceed 200 mm. When

studying the harvesting process by the method of combing on the root of soybean plants, a minimum loss

of soybean seeds (7.9 %) was obtained at an angular rotation speed of the combing drum 350 rpm and the

speed of the unit 11 km/ h.

Keywords: combing method, soybean harvesting, combing drum, installation angle, comb tooth length.
