RU2377758C2 - Potato harvesting machine separator - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the sphere of agricultural machinery immediately dealing with machinery for potato harvesting. The separator contains a set of rotors grouped into cascades that are arranged in parallel so that to enable their rotation in the same direction. The separator is designed as composed of spiral rotors consisting of right-hand and left-hand coil prigs and rod rotors with the rods arranged along the rotor generatrices. The rod and spiral rotors alternate to form cascades. The spirals are mounted so that to enable the bulbous mass displacement towards a rod rotor and displacement towards either an interface of spirals or the rotor edges.

EFFECT: improved reliability of the rotary separator during operation under rocky soil conditions.

Description

The invention relates to the field of agricultural machinery, in particular to machines for harvesting potatoes.

A number of designs are known: rotary bar cage according to the abstract Fedorov D.A. Improving the efficiency of potato harvesting by improving the design and technological parameters of a potato digger: abstract. dis. Cand. tech. Sciences / D.A. Fedorov. - Great Luke: Editorial and Publishing Department of the Supreme Agricultural Academy, 2005. - 20 p .; separator of impurities from root crops according to the certificate of authorship SU 1329657, cl. А01D 33/08, 06/27/1985; rotary separator according to copyright certificate SU 1727646, class. A01D 33/08, 04/23/1992.

Closest to the claimed invention by technical nature is a rotary separator according to copyright certificate SU 1727646, class. А01D 33/08, 04/23/1992 (adopted as a prototype), containing parallel rotors with the possibility of their rotation in one direction and arranged in cascades.

However, during the work of these working bodies as part of a potato harvester on stony soils, frequent stops of the working body, breakage and deformation of the separating elements (which causes a change in the size of the separating gaps, leading to damage and loss of tubers in the soil exceeding agrotechnical requirements) as a result of jamming of outsiders objects (stones) between the separating elements, which makes it difficult to use this working body when harvesting potatoes.

EFFECT: increased reliability of a rotary separator when working on stony soils.

The technical result is achieved by the fact that the rotary separator comprises a series of rotors arranged in cascades arranged in parallel with the possibility of rotation in one direction, the separator made of spiral rotors consisting of springs with left and right windings and rod rotors, the rods of which are located along the generators of the rotor, moreover, the rod and spiral rotors alternate, forming cascades, and the spirals are installed with the possibility of displacement of the tuberous mass to the rod rotor and displacement either to the joint of the spirals, or the edges of the rotors.

The drawing shows a diagram of the separator.

The separator consists of spiral 1 and rod 2 rotors mounted in parallel on the frame or sides of the potato harvester with the possibility of rotation in one direction, driven from the tractor power take-off shaft through a gearbox, chain or belt drive (the direction of movement of the tuberous mass is shown by arrows).

Spiral and rod rotors alternate, forming cascades consisting of a rod (the rods of which are located along the generators of the rotor) and spiral rotors. Spiral rotors consist of springs with right 3 and left 4 windings, and the springs in the spiral rotor of each subsequent cascade have opposite windings with respect to the spiral rotor of the previous cascade, which ensures the formation of a tuberous mass flow along converging and diverging flows.

The proposed device operates as follows.

During operation, the spiral rotors 1 of the separator simultaneously with the separation and transportation of the tuberous mass to the rod rotor shifts it either to the joint of the spirals or to the edges of the rotor (depending on the location of the springs), thereby equalizing the tuberous layer in width. Rod rotors 2 transport the tuberous mass, destroying soil lumps and separating it.

When foreign objects (stones) are jammed in the separating lumens of the spiral 1 and rod 2 rotors, this object collides with the separating surface of the adjacent rotor, as a result of which the spring of the spiral rotor is elastically deformed, which prevents plastic deformation or breakage of the separating elements of the rod rotor.
