Description

The invention relates to the field of agricultural engineering, namely to the working bodies for post-harvest processing of onions. purpose

inventions - increasing device performance and reducing bulb damage. The device contains a battery in pairs counter-rotating rollers with screw windings and limiters 2 mounted over each pair of rollers. Limiters 2 are made of circular cross-section, are installed movably in the circumferential direction and are equipped with mechanisms 9 and 10 for their drive, respectively, in a reciprocating circular and reciprocating motion relative to its axis. The reciprocating movement of the limiters 2 contributes to the advancement of the pinched bulbs for the rest of the pen. The reciprocating motion contributes to the release of the bulbs from pinching. 4 hp f-ly,

The invention relates to agricultural machinery, in particular to the working bodies for the processing of bulbous crops.

The purpose of the invention is to increase the performance of the device and reduce damage to the bulbs.

FIG. 1 shows a diagram of the device, a cross-section; in fig. 2 - the same, side view; see 3 drive mechanism ¹ limiters, top view; in fig. 4 - fragment of the limiter; in fig. 5 is a section A-A in FIG. 3

A device for separating the pen from the bulbs contains a battery of paired counter-rotating rollers 1 with screw windings, limiters 2 mounted above each pair of rollers 1 having loading zones 3 and unloading 4 bulbs. The section of the working surface of the limiters is made zigzag, and the surface itself is formed by sections 5 and 6 of different lengths. Section 5 is longer than section 6 and is located at an angle ¢ 6 = 3-7 ° to the axis of the limiter, and section 6 is located at an angle, p = 85-90 ° '. At both ends, the limiters 2 have support sections 7 installed in the guides 8. For the drive of the limiters 2, respectively, the device has mechanisms 9 and 10 in the reciprocating and reciprocating-circular movements, consisting of gear-pinion gear and three-center-spline systems, respectively. The pinion gear system consists of gears 11 mounted on stops 2 and rails 12 interacting with all gears 11. The rail 12 is connected to hinge 13 with a crank mechanism 14. The eccentric spline system consists of an eccentric shaft 15 with eccentrics 16 connected by means of a ball joint 17 with stops 2. The gears 11 are mounted between the stops 18 on the stops 2 by means of a sliding splined joint 19.

During operation, the rolls 1 of each pair rotate one towards the other. 55 mu, and limiters 2 mounted above them, make reciprocating and reciprocating circular motion at the same time.

The stroke of the stops 2 depends on the eccentricity of the cams of the eccentric shaft 15, and the angle of rotation depends on the radius of the crank gear 14 and the diameter of the gears 11. If necessary, the stops can perform one of the movements.

The device works as follows.

Onion heap served for processing in the area of 3 downloads. Screw coils capture feathers of the bulbs in the bottom of the interaction with their neighbors; rollers 1, where the separation of the pen from the bulbs. Limiters 2 do not allow the pen to be fully tightened between the rollers, so the separation of the pen from the bulbs occurs at the outflow from the shoulders of the bulbs, separated by agrotechnical requirements. Bulbs after separation, feathers are held between rollers 1 and limiters 2 for residues of feathers. The reciprocating circular motion of the stops 2 periodically releases the bulbs from jamming on one side of the stops 2, then on the other. But since rolls 1 rotate constantly in the same direction, this release does not always occur. The reciprocating movement of the stops 2 contributes to the advancement of the bulbs stuck between the rollers 1 and the stops 2 to the unloading zone 4. The proposed form of limiters 2 contributes to a more intensive advance of the stuck bulbs to zone 4. The main mass of the bulbs, separated from the pen and free from jamming, is rolled by the coils of the rollers to the unloading zone 4, the separated feather from the rollers 1 is removed from the device, and the bulbs are from the zone 4 unloading sent for further processing.

When processing a dry ripe onion heap, it is enough to give the Limiters only a reciprocating circular motion, when processing a wet heap with spindle-shaped Bulbs, an axial-reciprocating motion is attached to limiters, with intermediate indicators of the heap, both movements give.
