Description

The invention relates to agriculture, in particular to technical means for cleaning and drying grain.

Known grain cleaning and drying lines (complexes) KZS-25 and KZS-50, containing equipment for receiving grain, a grain reserve hopper, an air-sieve machine for preliminary cleaning of grain, a dryer, an air-sieve machine for primary grain cleaning, a block of trimers, bins for cleaned grain, feed fractions and waste, norias and other transporting means (Technologies, machines and equipment for the production, processing and storage of grain / Catalog. - M .: Informationgrotech, 1994. - P.236). The disadvantage of these lines is the low productivity and the inability to obtain high-quality seeds, since air-sieve lines do not carry out secondary grain cleaning. To obtain high-quality seeds, such lines must be additionally equipped with seed cleaning attachments containing a secondary grain cleaning machine, bunkers, elevators and other equipment, which leads to a significant complication and cost of lines. Rigid aggregate construction of lines determines the complexity, complexity and high cost of their installation. The lines do not have flexibility (adaptability), as a result of which, when changing the technology of grain processing, it is necessary to carry out a complex and expensive reconstruction of the lines.

The closest analogue of the proposed invention is a grain cleaning unit ZAV-20U-01, containing equipment for receiving grain, a grain reserve hopper, an air-sieve machine for preliminary cleaning of grain, a dryer, a universal air-sieve machine for primary and secondary grain cleaning, a block of trimers, hoppers for refined grain, feed fractions and waste, elevators and other transporting means (Machines and equipment for post-harvest grain processing / Catalog.- M .: FGNU "Rosinformagroteh", 2003. -P.165-166). This line provides high-quality seeds, since a universal air-sieve machine for primary and secondary grain cleaning provides secondary grain cleaning. The disadvantage of the line, as well as the above lines, is low productivity and rigid aggregate construction.

The technical result of the invention is to eliminate these drawbacks, namely: to increase the productivity of the line, to simplify, reduce the complexity and cost of installing the line, to provide the possibility of quick readjustment of the line when changing the technology of grain processing and to reduce the cost of its reconstruction.

The proposed grain-cleaning and drying technological line containing equipment for receiving grain, a grain reserve hopper, an air-sieve machine for preliminary cleaning of grain, a dryer, a universal air-sieve machine for primary and secondary grain cleaning, a block of trimers, bins for refined grain, feed fractions and waste , norias and other vehicles, differs from the closest analogue in that:

- the line is equipped instead of an air-sieve machine for preliminary cleaning of grain with a universal air-sieve machine for preliminary and primary cleaning of grain, capable of performing both preliminary and primary cleaning of grain;

- the line is equipped with transporting means, which, when wet grain arrives, allows the sequential operation of a universal air-sieve machine for preliminary and primary grain cleaning and a universal air-sieve machine for primary and secondary grain cleaning, while the first machine performs preliminary grain cleaning before drying, the second - primary grain cleaning after drying, and upon receipt of dry grain conveyance means of the line provide the possibility of parallel operation of these m ashin, while both machines carry out primary grain cleaning;

- the line is made in the form of separate modules: a grain receiving module, a grain reserve module, a preliminary and primary grain cleaning module, a grain drying module, a primary and secondary grain cleaning module, a grain cleaning module and cleaned grain storage modules, and the line modules are made in the form of metalwork on which the technological equipment is installed, elevators and other transporting means providing the supply of the processed grain and its fractions to the appropriate modules according to the specified processing technology grain.

An increase in the productivity of the proposed production line compared to the analogue is achieved by the fact that when a dry grain arrives at the dry grain line, the universal air-sieve machine for preliminary and primary grain cleaning is set to the primary grain cleaning mode and the initial grain is fed in parallel flows to this machine and the universal air-sieve machine primary and secondary cleaning of grain, while both machines carry out primary cleaning of grain.

Simplification, reduction of the complexity and cost of installing the line, the possibility of quick readjustment of the line when changing the grain processing technology and reducing the cost of reconstruction of the line are achieved by the fact that the line is made in the form of separate modules. This line design also makes it possible to quickly replace modules, as well as change their number and installation location in the line.

In Fig.1 and 2 depicts the process flow diagrams of the proposed line during the harvesting of grain from the fields (Fig.1 - flow diagram of the line upon receipt of wet grain, Fig.2 - flow diagram of the line upon receipt of dry grain), Fig.3 - technological scheme of the line in the post-harvest period.

The line contains a module for receiving grain 1, a module for reserve grain 2, a module for preliminary and primary cleaning of grain 3, a module for drying grain 4, a module for primary and secondary cleaning for grain 5, a module for grain cleaning 6, a storage module for purified grain 7, intermediate conveyors 9 and 10. The module receiving grain 1 contains a hopper; grain reserve module 2 - dual-flow noria 11 and a reserve hopper; module for preliminary and primary cleaning of grain 3 - a universal air-sieve machine for preliminary and primary cleaning of grain 12, a silo with sections for the feed fraction and waste, respectively, and elevator 13 for shipment of refined grain; the module for drying grain 4-noriya 14 for loading grain into the dryer 15, and the dryer 15; primary and secondary grain cleaning module 5 - a universal air-sieve machine for primary and secondary grain cleaning 16, a hopper with sections for the feed fraction and waste, respectively, and elevator 17 for shipping the refined grain; trimera cleaning module 6 —trimer block 18 for isolating short and long impurities from grain, a hopper for these impurities and elevator 19 for shipping refined grain; module-drive of refined grain 7 -bunker for refined grain.

Upon receipt of wet grain in the harvesting period, the line operates as follows (figure 1). Grain is unloaded from the dump truck into the hopper of the grain receiving module 1, from it it enters the first section of the two-line elevator 11 and is fed by this section to the universal air-sieve machine for preliminary and primary cleaning of grain 12, where it is preliminarily cleaned. If this machine does not cope with the flow of incoming grain, then part of it is poured into the hopper of the grain receiving module 1. The cleaned grain after the universal air-sieve machine for preliminary and primary cleaning of grain 12 with noriya 13 is loaded into the hopper of the grain reserve module 2, and the separated waste and feed the fraction enters the appropriate sections of the storage hopper of the module for preliminary and primary cleaning of grain 3. From the hopper of the module of the grain reserve 2, the grain is fed by an intermediate conveyor 9 to the noriya 14 and is loaded into the dryer by this noriya 15. After drying, the grain by the intermediate conveyor 10 is fed into the second section of the two-line elevator 11 and loaded into this section by a universal air-sieve machine for primary and secondary cleaning of grain 16, where it is primary purified. The cleaned grain after this machine is loaded with noria 17 into the hopper of the purified grain storage module 7. The waste and feed fraction separated in the universal air-sieve machine for primary and secondary grain cleaning 16 go to the corresponding sections of the hopper of the primary and secondary grain cleaning module 5. The cleaned grain from hoppers of the module for storage of refined grain 7, feed fractions and waste from the bins of the module for preliminary and primary cleaning of grain 3 and the module for primary and secondary cleaning of grain 5 are unloaded into cars.

Upon receipt of dry grain on the line during the harvesting period (Fig. 2), it is loaded from the hopper of the grain receiving module 1 by the first section of the two-line elevator 11 into the universal air-sieve machine for preliminary and primary grain cleaning 12 and into the universal air-sieve machine primary and secondary grain cleaning 16. In these machines, the primary cleaning of grain. If the machines do not cope with the flow of grain, then part of the grain in the second section of the dual-flow elevator 11 is fed into the hopper of the grain reserve module 2 and then, as the grain is consumed from the hopper of the grain intake module 1, it enters the first section of the dual-flow elevator 11 and is simultaneously fed into this universal air - a sieve machine for preliminary and primary cleaning of grain 12 and into a universal air-sieve machine for primary and secondary cleaning of grain 16. The cleaned grain after a universal air-sieve machine for preliminary and primary grain cleaning 12 and after the universal air-sieve machine for primary and secondary cleaning of grain 16 is loaded by elevators 13 and 17, respectively, into the hopper of the purified grain storage module 7. The waste and feed fractions extracted in the universal air-sieve machine for preliminary and primary grain cleaning 12 are received in the corresponding sections of the hopper of the module for preliminary and primary cleaning of grain 3, and the waste and feed fractions separated in the universal air-sieve machine for primary and secondary cleaning of grain 16 - in accordance with uyuschie hopper section of primary and secondary cleaning module 5.
