Description

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

 The purpose of the invention is to increase reliability and simplify the design.

 In FIG. 1 shows a divider of a flax harvester, side view; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 - BB section in FIG. 1; in FIG. 4 - lateral stems, top view; in FIG. 5 is the same side view; in FIG. 6 - swivel of the lateral stems and the dividing bar with the bracket of the top-lifting section.

 The divider of the flax harvesting machine comprises a support runner 1, lateral stalk bends 2, 3, pivotally connected to the support runner 1 and the frame 4 of the machine, and a dividing bar 5, the lower end of which is fixed to the support runner 1, and the upper end is mounted to rotate on the frame of the machine 4 The support runner 1 is hollow, and the front ends of the stems 2, 3 are interconnected, located inside the support skid 1 in the cavity 0-0 of the divider symmetry, while a longitudinal groove 6 is made at the junction of the stems 2, 3, in which olozhen joint 7. The upper end of the spacer bar 5 via a hinge 8 mounted on the frame 4 of the machine. Elastic elements 9 are mounted on the hinge 7 for attaching the lateral stems 2, 3 with the support slide 1 on both sides of the connected ends of the stems 2, 3. There are holes 11 for changing the position of the divider in the plates 10.

 Before starting work, the divider is set to its working position. In this case, the support runner 1 is placed above the field surface at a distance of 3-5 mm and is fixed in this position by installing the axis of the hinge 8 in one of the holes 11 of the plates 10. When moving along the field, the divider sock easily penetrates into the mass of stems, and the dividing bar 5 raises and divides the mass of stems into strips, which are directed by lateral stems 2, 3 to the belts of the top-lifting section, with which they are grafted from the soil. In the case of a collision with uneven soil (obstacles), the support runner 1 rises upward, the hinge 7 moves along the longitudinal groove 6 of the rectilinear section of the lateral stems 2, 3, which in turn also rotate upward around the axis of the hinges (pins) connecting them with the frame 4 cars. After overcoming the obstacle, the divider returns to its working position under the action of gravity. The hinge 7 thus slides along the longitudinal groove 6 until it stops in its end wall.

 A small angle of sharpness of the divider (sharp toe at the divider) is achieved due to the presence of a common rectilinear section of the lateral stems 2, 3, located in the hollow support runner 1, the side walls of which do not extend beyond the dimensions of the pipe of the dividing beam 5.

 The presence of elastic elements 9 allows you to position the divider along its longitudinal axis of O-O symmetry (the divider returns to its original position after overcoming the obstacle), which provides a more stable distance between the socks of adjacent dividers, which determine the grip width of the topping section, leading to a decrease in stretching stems in the ribbon.

 The implementation of the dividing bar 5 bearing (the center of rotation of the divider is the hinge 8), as well as the transfer of the compensator to the front of the divider (it is formed by a longitudinal groove 6 and the hinge 7) can increase the stability of the divider to the perception of loads in the vertical plane when copying obstacles and simplify the design, which increases the reliability of its work.
