Description

The invention relates to a threshing and hulling machine with which either Grain or small seeds are threshed, husked and completely cleaned can. Machines of this type are already known per se, in the case of the known machines but different means must be used for both types of threshing, which one must be replaced or switched on. According to the invention is now a easy use of such machines for both threshing grain and destroying pods of small seeds made possible by the fact that the same threshing drums and cleaning devices for threshing grain and peeling seeds are used that these devices but by adjusting slides and lifting devices when threshing in others The sequence is the same as for peeling.

The switching for the two types of use is expediently carried out in the manner that the slides and lifting devices, which the passage of the goods through the Determine machine, are switchable so that the crop is the first one after the other when threshing Threshing drum, the first cleaning device, the second threshing drum and the second Cleaning device and during peeling

of seeds successively through the first threshing drum, the second threshing drum, the first cleaning device and the second cleaning device. In the drawing, the subject matter of the invention is illustrated in an exemplary embodiment, namely Fig. Ι shows a longitudinal section, Fig. 2 is a section along line CD of Fig. 1 and Fig. 3 is a side view of the rear part of the machine.

In the drawing, A and B denote the first and second threshing drums with the concaves A ¹ and B ¹ , respectively, C the straw walkers, D the collecting board with the stages d, <f, '5 c? ² , d ³ and the large sieve F. G is the first sieve box with the sieves gj g ¹ , g ~, g ³ and with the stages e, e ¹ , e ", e ^3. H is the main elevator; L is the first Blower, M the second sieve box with the sieves m, m ¹ with the stages «ι ² , f» ⁸ , P the second 'blower, Λ ^Γ the sorting sieve with the brush 0. R are the outlet openings for the threshed material, among which the Bags are attached.

The threshing and husking of the grain takes place in a known manner by introducing it through the opening 0.

While the threshed straw emerges at r , the grain arrives partly directly in front of the drum A, partly via the straw shaker C on the collecting board D and the large sieve F, whereupon it is cleaned of the small straw emerging at t in the first sieve box G entry. After the grain has been cleaned of all foreign bodies in the same, it passes through the outlet K (Fig. 2) into the bucket elevator H, where it is conveyed to the threshing drum B , which in this case serves as a polishing mechanism.

From this the grain comes into the second sieve box and after passing through the sorting sieve Λ * to the outlets R.

When treating small seed crops, however, the process is as follows:

In the first threshing drum A , the husks containing the seeds are separated from the stalk.

While the straw makes its way over the straw walkers C , the husks and the small straw collect on the inclined surfaces d, d ¹ , whereupon on the large sieve / ^; the separation takes place. The small straw falls to the ground at t , the husks with the seeds get to steps d ² , cP and from these instead of in the first sieve box through a channel Ho (in Fig. 1 shown in dashed lines> immediately into the elevator H, in which they are lifted to the second threshing drum B , through which the seed is released from the husks. Loosely mixed, both slide over a slide b, which can be adjusted from the outside, to the sieve box Ii and over the inclined surface b ¹ and b ~, fall onto surface e and arrive now in the first sieve box G, where their separation and the first cleaning of the seed takes place.

Through a channel E (Fig. 3) branching off at the bottom of the sieve box G, the seeds reach a small lifting mechanism Q (Figs. 2 and 3), where they are lifted to the conveyor screw / and from there it is conveyed to the second sieve box M. Complete cleaning of the seed is achieved with the help of the second fan P , whose appropriately regulated air flow blows away all remaining additions and dust. The impurities fall down at e and take the same route as the husks to exit i.

The seed falls from the areas m ² , m ^B , bypassing the sorting sieve N through the passage χ arranged to the side of this (Fig. 2) and exits at the outlet openings R (Fig. I, 3). For this purpose, the opening in the inclined part of the bottom w ^s is blocked by a slide, so that the exit is only permitted through the opening in the horizontal part m ⁴ (Fig. 2).

Claims (2)

Patent Claims: 1. Threshing and husking machine for grain or small seed crops with two threshing drums and two cleaning devices, characterized in that that the same threshing drums and cleaning devices when threshing grain and peeling seeds can be used, but that they can be adjusted by adjusting slides and lifting devices When threshing, they are run through in a different order than when husking. 2. Threshing and hulling machine according to claim 1, characterized in that that the slides and lifting devices can be switched so that the crop hits the first threshing drum one after the other when threshing, the first cleaning device, the second threshing drum and the second cleaning device and during peeling of seeds one after the other the first threshing drum, the second threshing drum, the first cleaning device and the second cleaning device passes through. For this purpose 2 sheets of drawings.
