Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the quality of the roll by improving its cohesion and longitudinal rigidity. A device for forming a grain mass into a swath contains a reel having an even number of rows of slats. Spiral strips of each row were made with a one-way approach: strips 4 — with a right-hand approach; strips 5 — with a left-side approach. At the ends of the bar 4 and 5, they are connected by longitudinal bars 3. When the reel is rotated, the row of levee bars 5 captures the stems, bends them to the cutting unit and bends them to the left. After pruning, these stems are stacked on the conveyor with ears to the left of the direction of movement of the device. A layer of these stems is stacked by a portion of the stalks by the ears, along the direction of movement of the device. A number of right-handed strips 4 perform similar operations with the stems to the right. Thus, the alternation of directions for laying stems increases the coherence and longitudinal rigidity of the roll. 1 hp f-ly, 4 ill.

The invention (ls) of a plant for agricultural machinery and equipment, in particular, devices for forming rolls of bread mass.

The purpose of the invention is to improve the quality of the roll by improving its cohesion and longitudinal rigidity.

FIG. 1 shows a .model, general view; in fig. 2 the proposed device, a general view; in fig. 3 - alternation of the laying of the stems with spiral and longitudinal bars for one revolution of the reel; in fig. 4 - scheme of laying the stems in felling.

The device contains a reel having a shaft 1 on which longitudinal strips 3 are fastened by means of crosses 2. Two strips 4 and 5 are attached to the slats 3 with right-handed and left-handed approaches, respectively, and one-way slats at an angle of 30 are installed in each row. ° to reel axis and 400 mm tag. / 1lpna strips 2000 mm. The detachable sections are made of sheet metal with a thickness of 2 mm. The height of the slats 200 mm. The diameter of the reel 1400 mm. The distance between the longitudinal strips of one row along the circumference was 1.3 1.3 m, the distance between the strips of adjacent rows was 0.88 m.

The operating speed of the reel depends on the speed of the device. The ratio of the circumferential speed of the reel to the translational speed of the device is set within /. K4 ... 1.8.

Transport)) 6 is set in the direction of movement of the device. It is equipped with load-carrying elements, pulled in the form of fingers 7 and protruding above the flooring 8. Fingers 7 move in the direction opposite to the movement of the device. The conveyor operates in a two-speed mode: the accumulation of grain mass and its unloading on the stubble. In the accumulation mode, the fingers 7 move at a speed lower than the speed of the device. In the unloading mode, their speed is equal to the speed of movement of the mouth. In front of the conveyor 6 is placed the cutting unit 9.

Way to implement 1 with the next image.

The work of the reel is considered during the formation of the roll on the collection of schennitsy with a thickness of 400 HJT./M- and a height of stems of 70 cm.

Motovi, 1o is set so that the points farthest from the va: 1a 1 reel of both the longitudinal 3 and spiral 4 and 5 planks are immersed from the top of the stems to a depth equal to 1/3 of the length of the cut part of the stem on the same vertical with the cutting unit 9. The rotational speed of the reel is consistent with the forward speed of the device by the ratio /. 1.5.

When the reel rotates, for example, the row of fly-by-turn strips 5 captures the stems, bends them towards the cutting unit 9 and at the same time, as a result of sliding along the surface of the strips, bends them to the left. After cutting with the cutting unit 9, these stems are placed on the conveyor 6 with ears to the left of the direction of movement of the device. On the layer of these stems, which are displaced back by the conveyor 6, in the course of the rotation of the reel, a longitudinal plate 3 of the adjacent row after cutting with a cutting device 9 places a portion of the stems with spikes along the direction of movement of the device. A series of right-handed slats 4 captures the stems, bends them towards the cutting unit 9 and simultaneously, as a result of sliding along the surface of the slats, bends them to the right. After cutting with a cutting unit 9, these stems are laid with spikes to the right of the direction of movement of the device on a layer of stems, previously laid with a longitudinal bar of the adjacent row and shifted back by the conveyor 6. On a layer of stems, tipped to the right from the direction of movement of the device and shifted back by the conveyor , forward along the direction of the ripen. 1. longitudinal strap 3 of an adjacent row puts a layer of stems with tombs along the movement of the device, etc.

During one revolution of the reel, made of two rows of spiral slats, the grain weight on the conveyor belt is formed of four layers: | First (a) - to the left from the direction of movement of the device; the second (b) —wheels along the movement of the device; the third (c), with ears to the right of the direction of movement of the device; the fourth (d) - by the ears along the movement of the device (Fig. 3). At subsequent revolutions, the process of laying the stems is repeated.

Such an arrangement of the stems increases the longitudinal rigidity and cohesion of the crop rolls, which ultimately leads to a decrease in yield losses.
