Description

FLAX.

The utility model relates to agricultural machinery and can be used in flax harvesting machines.

Known flax tiller (AS USSR No. 275577, class A01D45 / 06, 1969), containing a system of top-lifting pulleys with deflecting pulleys; with rollers and a common endless tape enveloping the top-lifting pulleys that are installed behind the dividers. The distance between adjacent dividers forms a process stream.

The disadvantage of this flax saw is that the arches of the frame for fastening the pulley pulleys are located above the pulley pulleys, which, when flax pulping, leads to the distribution of process flows and rupture of the seeded apical part of the plant. When harvesting high-stalk flax, especially tangled and laid down, the stems overhang the arches of the frame, which leads to frequent clogging of the flax harvester and a deterioration in the quality and reliability of pulling. Due to this drawback, the total loss of seeds is up to 20%, and the machine becomes inoperative when harvesting laid flax. In addition, the quality of the products obtained is flax trusts, not high enough due to the elongation of the stems in the layer formed by the flax weevil.

Known flax tiller (Pat. RF No. 2086090, class A01D45 / 06, 1997, prototype), containing dividers, a number of top pulleys, enveloped by an endless top belt, and deflecting rollers. For each divider in a vertical plane on the frame there is a z-shaped

an arm, on the lower end of which a top-pulley is mounted, on which the roller is coaxially and sequentially mounted. Top-pulleys are mounted behind dividers in pairs. Two pulleys together form a process stream, therefore their diameter is approximately 2 times smaller than in a flax saw according to A.S. USSR №275577 (analogue).

When flax pulping, a clear increase in the quality of pulping and the reliability of the technological process was established, and it was also found that clinging ensures a purity of more than 99% and a seed loss of not more than 2%, i.e. in godelah agrotechnical requirements. But there is no improvement in the quality of the products obtained (in comparison with the analogue according to A.S. USSR. No. 275577), in other words, there is no decrease in the elongation of the stems in the layer formed by the flax grinder.

From the work of A.M. Ipatova “Theoretical foundations of the mechanical processing of stalks of bast crops, M .: Legprombytizdat, 1989, pp. 60-62, it is known that the suitability of a trust depends on the extension of the stems in the formed layer and is most pronounced at small stalk lengths. So, if for a layer with an average stem length of 70 cm, an increase in the standard deviation to 6 cm reduces the suitability of the trust by only 4%, then for a layer with a stem length of 60 cm, 20%, and for a layer with a stem length of 50 cm, by 60% .

Therefore, it is very important to get a layer with low stretching of stems when flaxing flax.

The problem solved by the claimed utility model is to reduce the extension of the stems in the layer during flax cultivation. The problem was solved by installing, in a flax grinder, containing; dividers fixed to the frame, behind which the pulley pulleys are placed in a row, enveloped by a pulley belt, and, for each divider in a vertical plane, an arcuate bracket is mounted on the frame, at the lower end of which is mounted

top pulley, on which the roller is coaxially and sequentially mounted, a divider in front of each top-lifting live.

The magnitude of the extension of the stems in the formed layer is largely determined by the width of the process stream. The width of the process flow is determined by the diameter of the topping pulleys and their number in the process stream (one pulley, but of a large diameter, for flax sawn TLN-1,5 (analogue) and 2 pulleys of small diameter for flax sawn timber TL-1,9 (prototype)).

From the analysis of possible structural schemes of flax milling machines, it is clear that the smallest extension of the stems in the layer can be obtained when each mulcher pulley forms a process flow. The diameter of the top pulley should be small, but

ensure purity of hauling within the limits of agrotechnical requirements - at least 99%.

Installing a divider in front of each pulling pulley in the flax chopper will provide a narrow process flow, since the distance between adjacent dividers will be small.

Compared with the prototype, twice the number of dividers will be installed on the same flax width (in front of each top pulley, and each top pulley has a small diameter, which is about 2 times smaller compared to the analog). Flax stalks, entering the top-lifting stream and limited by rods of dividers, deviate by an insignificant amount and form a layer of stems with a slight extension. The utility model is illustrated by drawings.

In FIG. 1 is a front view of a flax cutter; in FIG. 2 - the same section A-Anafig. 1.

Pulling pulleys 2 mounted on the lower ends of the arcuate brackets 3 of the frame 4.

The upper ends of the arcuate brackets 3 are mounted on the frame 4 in a vertical plane at the dividers 1. The endless top-lifting belt 5 is mounted on the drive 6 and driven 7 shafts of the flax puller and rounds the pulley pulleys.

The pressure rollers 8 limit the arc of clamping of the stems between the belt 5 and the surface of the rubberized top-lifting pulley 2. Behind each pulley 2 is a roller 9 installed sequentially and coaxially with it. It orientates the transportation of the butt part of the stems inside the bent bracket 3 (in the space between the upper and lower ends of the arc-shaped hf bracket 3). The output belt 10 displays and deploys 180 worn flax around the driven pulley 7 and spreads it into a belt between the wheels of the tractor.

Flax saw works as follows.

When moving flax-saws across the field, the ends of the dividers 1 are divided by a flax stalk into strips. With the dividers rods, the flax strip, gradually tapering, approaches the clamping point, where the flax stalks are clamped between the topping belt 5 and the surface of the rubberized topping pulley 2 on an arc bounded by two pressure rollers 8. During the passage of the layer of flax stalks in the clamping zone, the machine moves forward and pulls all the stems of the strip. When transporting on the arc of the next pulley, an incoming uncluttered layer is superimposed on the layer that came from the previous topping stream. The process of applying a new layer is repeated several times (in this technical solution 8 times). Reclaimed flax is discharged into the cavity of the stream between the topping 5 and removing 10 belts, it is rotated around the driven pulley by 180 ° and spreads into a belt between the wheels of the tractor. Correct laying

the tape is regulated by the position of the ejection point, which varies depending on the speed of movement of the unit.

The claimed flax pulverizer provides not only high quality of pulping and reliability of the technological process (purity of pulping is 99%, and seed loss is not more than 2%), but it also pulls flax with almost no stalks in the formed layer, which ultimately improves the quality of flax production.

A prototype of the claimed flax saw mill is made and tested in the field.
