SU1576145A1 - Method and apparatus for sorting fruits - Google Patents

Abstract

The invention relates to means for separating agricultural products into fractions by size during post-harvest processing or prior to sale. The purpose of the invention is to increase productivity, sorting accuracy and service life, as well as reduce injury to fruits. The method of sorting the fruits includes feeding the fruits to the belt sorting surface and communicating the belts m 2 in the working section of oscillations in the vertical and horizontal planes, and when processing the elongated fruits, giving the belts m 2 oscillations in the vertical plane in the unloading section 7. In the device for performing the method under belts in the working area there is a shaker, the cams 9 of which are mounted eccentrically, and the drum 11 with the pulley 12 is loosely mounted on them. The grooves of the 13 pulleys are parallel to each other and under angle to the axis of the drum. Built-in hivel on the discharge area 7 is made similar, but without pulleys. 2 sec. and 2 z. p. f-ly, 5 ill.

Claims (4)

Claim 1. A method for sorting fruits, including feeding the fruits to a belt sorting surface having a receiving, working and unloading sections, and communicating to the belts on the working section of vibrations in a vertical plane, characterized in that, in order to increase productivity and accuracy of sorting, as well as reduce injury fruits, belts in the working area at the same time with vibrations in the vertical plane lead to vibrations in the horizontal plane, and the frequency of vibrations in the vertical plane is greater than the frequency of vibrations in the horizontal plane. 2. The method of pop. 1, characterized in that the belts on the discharge section of the sorting surface are informed by vibrations in the vertical plane, the frequency of which is greater than the frequency of oscillations of the belts on the working section in the vertical plane. 3. A device for sorting fruits, containing a sorting surface formed by belts enveloping the pulleys mounted on the shafts, and having receiving, working and unloading sections, shakers mounted in the form of a cam shaft mounted under the belts, conveyors for removing fractions and shaft drives, which are different the fact that, in order to increase productivity, sorting accuracy and service life, as well as reduce injury to the fruit, the cams of the shaft mounted on the working section are eccentrically fixed to freely mounted drum with pulleys, the latter grooves are made parallel to one another and at an angle to the axis of the drum, and the belts are arranged in the grooves. 4. The device according to claim 3, characterized in that one of the shakers in the form of a cam shaft is located on the discharge section of the sorting surface, its cams are eccentrically mounted, and a drum is freely mounted on the latter, while the drive shaft made so that it provides the cam shaft at the discharge section with a rotational frequency ed greater than the rotation frequency of the cam shaft at the working section. ^{1 1} ........
