Abstract

1. METHOD FOR WASTE THROWING OF THE TICKLE, which includes stripping boxes, pre-cleaning the resulting heap on the sieves and extracting from. seed pods on a shelling and separating unit, characterized in that, in order to increase the efficiency and productivity of threshing, in the process of pre-cleaning, the green pods are removed from the dry pods and their subsequent removal from further processing. 2. A method according to claim 1, of which it is possible so that during the pre-cleaning process the selection of free seeds is carried out from the pile, followed by their withdrawal from further processing.

Description

L, fO ff t-4 ft i The invention relates to agriculture and can be used in the process of cleaning the castor-gum castor gum harvester. There is a method of threshing castor bean, including the tow of boxes, their threshing and cleaning of the heap tl. There is also known a method of threshing castor bean, which includes, first and foremost, the preliminary cleaning of the heap obtained on the sieves and the isolation of seed boxes on the shelling and separating block C2T. A common drawback of the known methods is that the peeling (threshing), together with the combed dry boxes, are served green boxes and are located in a pile of free seeds. The castor bean matures non-simultaneously, therefore, for the period of harvesting, there are dry and green boxes on the plants. The green boxes have high humidity (60-70%) and therefore cannot be threshed without pre-drying. Under favorable harvesting conditions, the mass of green bolls in relation to the mass of the entire pile entering the threshing unit (shelling unit is 15-20%, and in some years it reaches 50%. The content of free seeds varies from 10 to 30%. These fractions are released during the process of combing the bolls from the plants. The supply of green bolls and free seeds to the threshing (shelling) unit leads to a decrease in threshing performance and efficiency. The purpose of the invention is to increase the efficiency and productivity of threshing. since during the pre-cleaning process the green boxes are separated from the dry ones and then removed from the further processing process; in the pre-cleaning process, free seeds are removed from the pile and then removed from the further processing process; In Fig. 1 schematically shows a combine for cleaning castor beans with its threshing according to the proposed method, side view, in Fig. 2 - a pre-cleaning unit.

The harvester consists of a combing device 1 of pin type, keyboard straw walker 2, screen 3, pre-cleaning, including an upper sieve 4 about an extension 5, a lower sieve 6 with a tray 7 installed under it, a sloping board 8 in which the entire width of the cut is cut out flow from the fan 9 remaining part of the sporos.

60 ha coming from the bottom sieve 6 enters the pitched board 8 and then through the window into it enters the transport device 14, from where it comes to the threshing machine 10 shear-and-blew65 of the steering unit. Along the process, the windows and the fan 9, the shelling and separating unit, including the threshing machine 10, the sieve 11 and two exhausters 12. The combine has conveying devices 13-15, respectively, for seeds, for heaps and for green bolls, separated in the pre-cleaning process; an pneumatic elevator 16 for transporting the finished product (seeds) to the hopper 17, the bunker 18 for green bolls, and the chopper 19 of the leaf stem. Tray 7 is made of a combination of sheet iron and a punch sieve. The latter is fixed at the end of tray 7 in the direction of the seeds selected by the bottom sieve 6. The windows in the tilted board are cut successively along the process in places that allow the fractions separated during the pre-cleaning process. heap. They are carved across the entire width of the pitched board 8. Sieve 4 and 6 have oblong holes (sieve 4 is 1820 mm wide, and sieve 6 is 8 mm wide). The harvester works on the proposed method as follows. From the combing device 1 and the straw walker 2, a pile consisting of dry and green bolls, tretinki, free seeds and weed impurity goes to screen 3 and then to pre-screen sieve 4. Due to the fact that dry boxes unlike green spikes break off during their transportation through the working bodies of the combine, dry boxes fall onto the lower sieve 6, and the green ones go off the sieve 4, fall through the holes of the extension 5 and further, moving along cattle board 8 through a window cut out in it, enters transporting device 15 and is transferred to bunker 18 for green bolls. The threshed seeds and small weed impurities from the sieve 6 fall onto tray 7, from which the seeds enter the transport device 13 and then are fed into the bunker 17. The small weed impurity (seeded out), selected on the sieve surface of the tray 7, falls on the ramp board 8 and further through a window in it is thrown out of the thresher.

The threshed heap enters at 11. Light impurities (husks) are blown out by exhausters 12. Seeds that have passed through the sieve holes 11 enter the channel of the pneumatic elevator 16 and further into the bunker 17.

Castor stems, descended from the straw walker 2, enter the shredder 19 and are scattered across the field.

As studies have shown, in the implementation of the proposed method on a preliminary

Up to 90% of green bolls from their total content and about 16% of threshed (free) seeds are removed from Vorotka.

Thus, by unloading the shelling-separating “block, it is possible to increase the supply of dry heap to it, by 30-35%, and, consequently, to increase the threshing output. In addition, efficiency is improved.

of the process, since the lithium-separating unit receives a more homogeneous array of heaps.
