Description

The calibrating machines for fruits, siabzhennymi mechanisms that change their cross-section by moving the adjustment of the device in a closed guide.

The described fruit calibration device is simpler in its design, in comparison with the known ones, and prevents the fruit from being damaged during its caliber.

From the known, the described device ot.hichitsa those. That each. Calibration mechanism; vgo is made in the form of a spring ring and a ring with a war | zh.chm zhchbchatym crown, between which the wire yarns are pulled across the entire perimeter, and forming the surface rotational heap fiber, average calibration diameter of which is 3 | Men. when moving the toothed rack connected through the rollers to a horizontally placed cam and toothed ring crown.

On the fit. : m 2 shows a diagram of the guiding and driving mechanisms (view in plan and along arrow A); in fig. 3 and 4 is a diagram of the calibrating mechanism (the fork in the plan and section across the device).

On the master disk / (FIG. 1), there are mounted calibrating mechanisms 2, which by rollers 3 move along a fixed cam 4, with their profile ensuring the corresponding movement of the gear racks 5, which causes a gradual change of the calibrating diameter from minimum a (position II) to maximum ( .unit P - P). On the section 1P - P1 -I-I and II-II -iV-IV, the profile of cam 4 provides an abrupt change in the calibration of its diameter 1. from the maximum to the minimum for future calibration. The delivery of the fruit at the conveyor nominee 6 occurs simultaneously from two sides in sections I-I and IV-IV (with a minimum calibrating digameter) and with a certain frequency. The disk 1 moves along the supporting rollers 7. The roller, and 7 and the cam 4 are fastened to the uprights 8, which are fixed on the table 9. The disk / receives its protection from the electric motor through the gearbox 10 and a pair of conical gears 11, 12. Calibrated fruits of the calibrating short-circuit mechanism 2 fall on the radially located trays 13 and further in box 14, and in the box fall p.yudy corresponding diameter.

The cadibing mechanism (see phi; g. 3 and 4) consists of a body 15 (fig. 4) to which the cover 16 and the receiving funnel 17 are attached. In the upper part of the body, a ring 19 is mounted on the springs 18, having a vertical movement along the guides rods 20. In the lid 21, there is a stick 22 with a notched boar, which is engaged with the iiepeMeiiiaroLiijiic; zodchachip .f-iKOi 5 (. 3. In order to reduce the trend and increase the stability of the ring 22 (Fig. 4), the latter moves on the balls 23 through the housing 15. With the help of the spring 24 (Fig. 3) the rack rail .5 is always pressed against cam 4 (fig. 1). The calibrating variable diameter 25 (fig. 3) is formed by a transverse middle section of a rotary wheel hyperboloid, the surface of which is obr: azo wana 26 strings (nylon or from pre-holes, etc.) The upper ends of the threads are fixed on the ring 19 (Fig. 4), and the lower ends on the ring 22 with a crown. The springs / S constantly ensure the tension of the threads 26 (Fig. 3). When the disk rotates / (Fig. I) the gear rack 5, b. of the cam-4 profile, moves and rotates the ring 22 (Fig. 4) in one direction or another relative to the ring 19. The fruit 27 falls from the conveyor to the calibration mechanism at the moment when the transverse mid section of the hyperboloid of rotation has a minimum diameter. As it moves, the calibrating diameter changes and when the diameter of the fruit is equal to or slightly smaller than the diameter of its diameter, the ii-3 rolls down (3) FIG. 1) in W, IR 14. Kalbrund mechanisms are attached to g DCCH / screws 28 (FIG. 3).

P p d d x C: T I 3 O b e p t e i

A device for calibrating fruits, made in the form of a disk with calibration mechanisms, rotating around a stationary horizontally mounted cam, characterized in that, in order to protect the fruits from damage during calibration, each calibration mechanism of the device is made in the form of an upper sub-spring: ;;; rings and an outer ring with an external toothed crown, between which the systemic wire and the like threads that stretch across the entire perimeter are systemic wire and the like, forming the surface of a hyper-boloid of rotation, the average gauge diameter which varies with movement x of the toothed rack, mating through rollers with horizontal cams and set with a ring gear ring.
