SU82333A1 - Machine for the manual sorting of the drop of pome fruits - Google Patents

Description

There are known devices for manual sorting of the seed fruits of the seeds, made in the form of an inclined table for manual bulkheading of fruits, with hatches for individual grades of the product being sorted and with a hopper equipped with a sliding gate with an elastic curtain.

In such devices, the fruits and the exit from the bunker past the gate valve are damaged, and the periodic release of the fruit from the bunker to the sorter, the table is not mechanized and makes it difficult for the sorter to work.

In the proposed machine, these disadvantages are eliminated by the fact that several parallel rows of cushion cords are stretched inside the bunker. The damper gate is made in the form of a movable frame, consisting of a series of parallel, freely growing shafts separated from the fruit mass by an elastic curtain, and the control of the slide gate is controlled by a foot pedal.

FIG. 1 schematically shows a sorting machine, front view; machine, plan view in fig. 2; in fig. 3, the same section along A-A in FIG. one; in fig. 4 - the position of the closed and in FIG. O - the open gate.

On the wooden frame / reinforced bunker 2, inside which several parallel rows of cushion cords 3 are pulled.

The extension of the sloping bottom 4 of the bunker is a sorting table 5, covered with canvas cloth and bordered by wooden boards 6 forming a triangle.

The table has hatches: 7, 8 - 9 above bunkers DL / I, IV and V varieties of fruit, located under the sorting table 5 and equipped with flaps 10 and hatches // and 12 dl / and // varieties of fruits, under which special boxes are installed sites 13 and 14.

The front wall 15 of the hopper 2 has a rectangular opening, but the edges of which have guide rails 16 sec. Lifting frame 17. Inside the latter, freely rotating rollers 18 are inserted, the curtain 19 is attached to the bottom, the upper edge

which is fixed to the front wall of the 15 bunker. The frame 17 is connected t gami 20 with the pedal 21, pivotally reinforced at the bottom of the frame 1.

Behind the bunker 2 there is a trellis area 22 for boxes with fruits to be sorted. A height-adjustable chair 23 is installed in front of the machine for the sorter worker.

Work on the machine is as follows. In the bunker 2, when the gate is closed, the fruits or vegetables to be sorted are poured, and their stock in boxes is placed on the platform 22.

The worker-sorter, sitting on the chair 23, pressing his foot on the pedal 21, lifts the bars 20, and thus the frame 17, upwards (Fig. 5).

The upward movement of the frame 17 is accompanied by the rotation of the rollers 18 around its axis, which, when interacting with the curtain 19, prevents the fruits from being damaged in the momentary movement of the shutter.

Fruits through the opening at the bottom of the bunker are poured out onto table 5, and the intensity of expelling the fruit from the bunker is reduced due to the damping of the area. 3, which also reduces fruit damage.

After releasing enough fruits from the bunker, the worker releases the pedal 2 and the frame 17 under the action of its own weight drops down.

Manually selecting the fruit of any degree of damage, the worker lowers them into the hatches for the corresponding varieties and, as necessary, presses the pedal 21, releasing the required number of fruits from the bunker 2 to the table 5.

The machine is intended for use at harvesting and commercial processing of seed fruits and vegetables, if necessary, to sort them into five or less varieties.

Subject and title
