Abstract

Using the invention relates to the mechanization of processing and transportation of objects from a random heap and is aimed at reducing the energy intensity of the process and injuring objects. SUMMARY OF THE INVENTION: A method for feeding items from a random pile includes feeding items into a loading hopper and distributing them by vibration in a horizontal plane on a conveyor. What is new is that the loading process is carried out with the formation of the angle of repose of the objects in the direction of their transportation. An elastic web with piezoelectric pathogens and pressure sensors mounted therein is used as a conveyor surface. 3 ill.

Description

The invention relates to agriculture, in particular to the supply of fruit from a random pile to sorting devices.

A method for wave transporting objects is known when objects are in several layers in the cavity of a transporting wave.

The purpose of the invention is to reduce the energy intensity of the process of feeding and injuring objects.

To do this, the objects are fed into the loading hopper with the formation of a natural angle in the direction of their transportation, and an elastic web with piezoelectric exciters mounted in it is used as the conveying surface of the conveyor to form the conveying wave and pressure sensors to determine the start of the wave when placing the objects on web surfaces in less than two layers.

Figure 1 shows a transporting body with an arbitrary pile of objects; in Fig.2 - the beginning of the transporting wave; Fig. 3 - division of an arbitrary pile into a single-layer row of objects.

The device includes a conveyor conveyor surface consisting of an elastic web 1 with piezoelectric exciters 2 mounted therein, pressure sensors 3, a rigid base 4, and a control unit 5.

The method of feeding items is as follows.

An arbitrary pile of objects capable of rolling is poured directly onto the conveying surface of the conveyor 1, with the formation of an angle of repose in the direction of their transportation (Fig. 1). After that, through the block

control 5 commands the piezoelectric drivers 2 to generate a transport wave, starting from objects located on the conveyor surface in less than two layers. The beginning of the wave is determined using Pressure Sensors 3 (Fig. 2). During operation of the conveying device, objects located therein in less than two layers begin to move toward the discharge end of the conveyor. At the same time, there is an arbitrary rolling of objects into the vacated place and their further transportation. At the same time, the control unit 5 receives signals from pressure sensors 3 to turn on new piezoelectric pathogens 2, above which the pressure does not exceed the pressure of two layers of objects. Thus, a direct separation of an arbitrary pile into a single-layer row of objects occurs (Fig. 3).
