SU816424A1 - Machine for threshing flax heap with obtaining pure seeds - Google Patents

Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery industry and may. to be used in flax heap processing machines.

Known machines for processing flax heap (MB-2, 5A, BP - 1.2, ML-2, 8P) are known, in which coarse flax pile is first ground in grater apparatus of various designs, and then supplied for separation to the screen or straw stalk, where it is divided into two fractions: 1 - the straw brover part and 2 - a small pile, which includes the seeds of the main crop and weed seeds, minkina (chaff), small organic and inorganic impurities. The first fraction is removed from the machine, and the second fraction is fed entirely to the machine for sorting (cleaning) the machine. The seeds of the main crop are isolated from a small pile.

The performance of known machines is limited mainly by the throughput of cleaning.

The disadvantage of the machines is: the fact that the cleaning comes to the main part of the small pile, which causes a repetition of the cleaning sieves.

Closest to the proposed seed cleaning machine, it contains a feed conveyor, an oscillating groove with a set of sieves, trowels, and wind-screen cleaning 2.

A disadvantage of the known machine is that the entire bulk of the pile enters the cleaning, which causes an overload of cleaning.

The purpose of the invention is to improve the carrying capacity of the wind-sieve cleaning and the machine in the chain.

This goal is achieved by the fact that the screen is provided with a shim-plate pejiieTCM with a pallet connected tightly by means of a discharge tray with a floor collector in which the exhauster is installed.

FIG. 1 shows a car, side view; in fig. 2 - the same kind of CBepixy. The machine consists of a loading conveyor 1, a front screen 2, a grater 3 of the first flow, a grater 4 of the second flow, a rear grokot 5, a screw 6 with an elevator 7 of the second flow, a screw 8 with an elevator 9 of the first flow, a two-section shaft 1O Tray 11, collector 12 with exhauster 13 and discharge pipe 14. Front screen 2 consists of 2 passages and one lower seeded sieve. The working size of the holes of the second sieve of the front screen 2 is smaller than the diameter of the flax boxes. A pallet 15 is installed under the sowing sieve, which is rigidly connected to the discharge chute 11 The discharge chute J. 1 is placed at the other end of the floor into the floor board 12. The machine works as follows. A coarse flax heap along the loading conveyor 1 enters the upper sieve of the front screen 2. The passage through the openings of the upper sieve is a small pile on the second sieve with oblong holes, with the working size of the openings smaller than the diameter of the box. From the top sieve, fragments of the stems from the neotorpan paths (confusion) go into the grater 4. Rubbed confusion enters the rear screen 5. Passing through the holes of the sieve, the back screen 5 goes to a small pile on the pallet 15, and the confusion goes on from the second screen of the front screen, there are free flax seeds, weed seeds, small organic and inorganic impurities, and coming off from the second sieve go to grate 3 whole boxes, free from weeds nk chaff). The heap from the frayed bolls is guided by the screw 8 and the elevator 9 to the section of the first flow of the two-section wind-stilt shaft 1O. Small impurities (small weed seeds, organic and inorganic impurities), smaller seed sizes, which are directed by the screen tray to the closed discharge chute 11 and the vacuum section, are passed through the lower sifting sieve of the front screen 2. created by exauss8 44 ter 13, these small impurities are introduced into the floor collection 12 and, together with the genitalia, are removed from the machine by the exhauster 13 through line 14. From the lower sieve of the front screen, 2 free flax seeds and impurities, large according to the size of the sieve holes, they are placed in the rear screen pan 5 and together with a small pile of mud from the confusion on the back screen 5 are guided by the screw 6 and the elevator 7 to the second section of the windshield bar 10. At the wind screen 10, the wind screen 10 is separated flows, and the allocated field is directed by the fan to the collector 12 and the exhauster 13 is passed through pipeline 14 from the machine. According to the research data of the Scientific and Research Institute, coarse flax heap contains up to 1–12% of small impurities that are smaller in size (small chaff, organic and inorganic impurities, small weed seeds, etc.). The removal of these impurities from the machine before feeding the pile into the grating apparatus of the machine, and later on in the winding, allows the machine to unload or increase its load by at least 10%, which will increase the throughput of the machine as minimum as a whole. % Claims for flax heap processing to obtain pure seeds, containing a loading conveyor, an oscillating screen with a set of sieves, trowel and wind-sieve cleaning, in order to increase the throughput windshield cleaning and machine in business, the screen is equipped with a sowing sieve with podonsad, connected hermetically by means of a discharge tray with a floor collector in which the extractor is installed.
