Изобретение относитс к сельскому хоз йству , в частности к картофелеуборочным машинам, и предназначено дл разделени вороха, содержащего сыпучую (земл ), твердую (камни, клубни картофел ) и стеблевидную растительную (ботва, сорн ки, стерн ) фракции.The invention relates to agriculture, in particular to potato harvesting machines, and is intended for the separation of a pile containing loose (earth), solid (stones, potato tubers) and stem plant (tops, weeds, stern) fractions.

Известно сепарирующее устройство к картофелеуборочным машинам, содержащее подающий транспортер и средство дл разделени сыпучей, твердой и стеблевидной растительной фракции. В известном уст ройстве средство дл разделени фракций представл ет собой два последовательно расположенных транспортера, выполненных в виде р да бесконечных клиновидных ремней , образующих решетку. Привод транспортеров осуществл етс от вала трактора через карданный вал и далее через цепные иЗубчатые передачи 1.A separating device for potato harvesters is known, which contains a feed conveyor and means for separating loose, solid and stem plant fractions. In the known device, the means for separating the fractions are two consecutive conveyors made in the form of a series of endless wedge-shaped belts forming a grid. The conveyors are driven from the tractor shaft through the cardan shaft and further through the chain and gear drives 1.

Данное устройство содержит только один ленточный транспортер, что упрощает его конструкцию. Кроме того, в этом устройстве возможно проваливание вместе с клубн ми картофел и стеблевидной фракции, поскольку рассто ни между ремн ми достаточно большие.This device contains only one belt conveyor, which simplifies its design. In addition, it is possible for this device to fail along with tubers of potatoes and the stem-like fraction, since the distances between the belts are rather large.

Цель изобретени - повышение качества сепарировани и упрощение конструкции .The purpose of the invention is to improve the quality of separation and simplify the design.

Указанна цель достигаетс тем, что средство дл разделени фракций выполнено в виде ленточно-пальцевого транспортера , над которым установлена двухскатна пруткова рещетка, при этом пальцы ленточного транспортера вход т в промежутки между прутками решетки.This goal is achieved by the fact that the means for separating fractions are made in the form of a belt-finger conveyor, over which a double-bar rod is installed, with the fingers of the belt conveyor entering the spaces between the bars of the grid.

На фиг. 1 показано схематически устройство , вид сбоку; на фиг. 2 - разрез А-А на фиг. I.FIG. 1 shows a schematic side view of the device; in fig. 2 shows section A-A in FIG. I.

Сепарирующее устройство к картофелеуборочным машинам включает подающий транспортер 1, под которым размещен ленточный , транспортер 2 с пальцами 3, рама которого крепитс к бункеру 4. Над транспортером 2 установлена двухскатна пруткова решетка 5, котора также крепитс к бункеру. Дл сужени потока вороха, поступающего с транспортера 1, на бортах егоThe separating device for potato harvesters includes a feeding conveyor 1, under which a belt conveyor is placed, a conveyor 2 with fingers 3, the frame of which is attached to the bunker 4. A dual-slope bar 5 is installed above the conveyor 2, which is also attached to the bunker. To constrict the flow of the heap coming from the conveyor 1 on its sides

Claims

flaps 6 are installed. Grid 5, in addition to certain angles of inclination of the lateral sides (оС), may have a common angle of inclination to the horizon (J3), which is less than the angle of friction of each of the components of the pile. The conveyor 2 is driven by a chain drive consisting of a leading sprocket 7 of which is screwed to the drum by means of three fractions: bulk (ground), solid (potato tubers or stones), and stem-like vegetable (tops, sorbitra) , stern), from the conveyor 1 falls on the double-slope bar grating 5 In the process of falling, the heap is divided into fractions. Stones (or potatoes) roll down the sides of the grille down into the bunker 4. The bulk part (earth) basically falls through the grill 2. The slice remains on the grill, where it is picked up by the fingers 3 of the conveyor 2 and is also removed. When it moves along the grate, the vegetable mass cleans the grate from hanging on the ground rods. The proposed device is compact and fulfills the function of several separating bodies in the device. In this case, the solid fraction (for example, potato tubers) is released from the pile at the very beginning of the separation process and enters the bunker, as a result of which the separation process is simplified, and hence the design of the machine. At the same time, the quality of separation also increases. DETAILED DESCRIPTION OF THE INVENTION A separating device for potato harvesters comprising a feed conveyor and means for separating loose, solid, and stem-shaped stretcher of an NOI fraction, characterized in that it has a quality material. design and improvement of the quality of separation, the means for separating fractions is made in the form of a flax-finger-conveyor belt, over 1TshTp peiEeT ka, while the fingers of the conveyor belt are spacing between the rods Sources of information taken into account during the examination of P 7Qt.i I ° P ° certificate USSR 795568, cl.
