Abstract

The invention relates to the field of agricultural engineering, in particular to machines for harvesting a year. The goal is to reduce damage to plants and losses a year. The harvester's harvester contains a pair of shafts 4 and 5 with axles 5 and 7 arranged in parallel, and makes an angle with the plane of the direction of movement of the machine. On each of the shafts, along the entire length, holders 8 are arranged in a row, in which pests 9 are rigidly fixed. A number of scourges 9 on each of the shafts form a tapering channel to their ends. When processing bushes in the channel of the hivetel, there is a message of oscillations of the branches m in the upper part of the bush, more than in the lower part. In addition, when the bush enters the channel of the stitcher, the upper part of the bush is mainly affected by the scourge, and when the bush leaves the canal, the lower part is predominantly affected. 3 il.

Description

The invention relates to the field of agricultural engineering, in particular to machines for harvesting a year.

The purpose of the invention is to reduce damage to plants and losses a year.

The invention is illustrated in the drawing, where in FIG. 1 shows a page of a hivatel (view of a page hivatel of a harvester on the side), in fig. 2 is a view A of FIG. 1, in FIG. 3 - front view of the policyholder.

The harvester's harvester contains an IT frame 1, on which shafts 4 and 5, bearing axes 6 and 7, are installed in bearing assemblies 2 and 3. The axes of shafts 6 and 7 are parallel and are located in the longitudinal plane of the hive, so that the composition of the angle is and with direction V of the harvesting machine. On each of Bi-lov 4 and 5, along the entire length, holders 8 are located in a row, in which oichi 9 are rigidly fixed.

Rows of scourges 9 on each of shafts 4 and 5 form a channel narrowing towards their ends. The end of each scourge 9 (except the bottom one) is adjacent to the end of the neighboring Si, 82, etc. in the direction of the corresponding shaft 4 and 5. On each of the shafts 4 and 5, the lugs 10 and 11, respectively, are connected rigidly with each other by a hinge thrust 12. On the lug 11 there is also a connecting rod 13, which informs a torsional drive around axes 6 and 7 4 and 5. The frame of the hivatel 1 is fixed to the chassis 14 of the harvesting machine with the help of hinges 15 (on both sides of the frame) and hydraulic cylinders 16 and 17.

The streamer works as follows.

When the harvester moves in the V direction, the channels formed by a series of scourges 9 on shafts 4 and 5 get into pieces 18, 19 and 20. The connecting rod 13, performing reciprocating movement, communicates through a four-link mechanism consisting of lugs 10 and 11 and ti 12, torsional single-phase oscillations around axes 6 and 7, respectively, shafts 4 and 5. As a result, each point of the blade receives a transverse displacement, the magnitude of which increases with distance from the shaft axis. Therefore, bush 19, being located in the channel of the spivator channel, receives oscillations of different amplitude upon contact with the scourges 9. At point B, the oscillation amplitude will be minimal and is determined by the value B162 (see FIG. 3), and at point C - the maximum (distance CiC2). However, the time spent by the bush is 19

when all the whips 9 are affected by the canal 9, the smaller number of scourges 9 affect the canal 18 when the bush 18 enters the canal and when the bush 20 leaves the canal. As the bush 18 enters the canal 9, it affects only the upper part of the canal and as it advances in the channel, the zone of impact on the bush increases. In this case, the oscillation amplitude is also gradually

decreases from the top of the bush 18 to the zone that begins to contact with the whip 9. When the bush 20 leaves the canal page, its upper part is gradually released from contact with the whips 9, while its bottom

the part is still exposed to them. In this case, the compacted upper part of the hive 20 is spread out, while the hive 20 itself is still subject to vibration. At this point, the unconsolidated crown of the hive 20 is shaken, resulting in a separation, but still on the crown, years beyond its limits, which reduces the loss of a year.

During the work of the builder, the time that the bushes are in the zone of action of all the scourges 9 is reduced, which leads to a decrease in the damage of the branches. However, the total energy impact on the treated

The bush remains the same, since the branches get oscillations when entering the channel of the hivetel and upon leaving it. But in these cases, a less dense crown of the bush is processed, which reduces the mutual displacement (and as a result of breakage) of the elements of the crown of the bush.

The presence of hinges 15 and hydraulic cylinders 16 and 17 in the construction of the strap assembly allows the angle of inclination of the “axes 6” to be adjusted.

and 7, which is necessary when choosing the optimal mode of the stitcher when processing various crops and their varieties, differing in crown structure and physicomechanical properties.

Claims (1)

Claims of the year harvester machine containing a pair of shafts mounted on the frame with the possibility of oscillations, along each of which a row of whips of the same length are placed, and a drive that is different from the fact that in order to reduce damage to plants and losses a year, parallel to the longitudinal axis of the frame planes with an inclination of their upper ends in the direction of movement of the machine with the possibility of adjusting the angle of inclination. // f /
