Description

(54) MACHINE FOR CLEANING BULBS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for harvesting root crops, namely tulip and narcissus bulbs.

Known machine for harvesting of tubers, containing the copying mechanism, pressure testing, digging up the plowshares and the separating device 1.

The disadvantage of this machine is the absence of a device that prevents the leaves of plants, weeds and top soil from entering the heap, which reduces the productivity of the separating organs and the purity of the recovered product. In addition to the TGO, the breaking up of the compressed and loosened mass with tubers when it is transferred from the rollers to the excavating plowshares contributes to the increase in losses and damage.

The aim of the invention is to improve the separation of vegetation and soil from the bulbs and reduce their loss.

The goal is achieved in that the plowshare is made with furrow-forming dumps, equipped with a drive of oscillatory motion and

placed in front of the opressovschikom, behind which are mounted on the frame of the guides. FIG. 1 shows a side view of a flower crop cleaning machine; in fig. 2 - the same, top view; in fig. 3 -

 three projections of pruning-profiling working body; in fig. 4 shows section A-A in FIG. one; in fig. 5 is a section BB in FIG. 1, a diagram explaining the operation of the press rollers and guide plates.

10 A flower harvesting machine consists of sections supported on a copying wheel 1, each of which contains an active knife 2 with two furrowing plowshares 3 and dumps 4, pressing rollers 5, adjustable to

 height with screw mechanisms 6 and 7, guide plates 8, trough-shaped cops 9 with a sieve and screen 10 mounted on hangers 11. Drive of knives 2, cops 9 and screens 10 with relative displacement

20 phases at 120 ° is carried out by means of the crank mechanism 12 through the pushers 13, 14 and 15. The front part of the machine is equipped with a turning device for correcting the direction of movement, consisting

from the hydraulic cylinder 16 and the drawbar 17. The rear part of the machine, both in the working and transport position, rests on the wheels 18. The drive of the machine is dried out from the power take-off shaft, and the control is driven by the use of the tractor's hydraulic system.

The machine works in the following way.

When the machine is moving across the field, it is copied, its wheel 1 (Fig. 1 and 2), located in the central aisle, maintains the set processing depth by all working bodies. Active knives 2 (Fig. 3) each in their row cut off the leaf part of the plants, the surface soil layer and together with the plowshares 3 and the dumps 4 form a comb-like profile, saturated with onions, into which the pressing roller pairs are easily inserted. The stems of tulips or daffodils, plant residues along with the surface layer of soil are thrown between the rows (Fig. 4). Formed ridges are compressed by rollers 5 (Fig. 5), which makes it possible to obtain a loosened soil layer with bulbs, which is removed and guided in pairs of flaps 8 to the cops 9.

The guides prevent the loosened mass from falling apart and reduce bulb loss. The swing screens 10 separate the heaps and feed the bulbs into the unloading and filling device.

The application of the proposed machine allows to improve the separation of the bulbs from the vegetation and soil, to increase the productivity and quality of their harvesting.
