Mowing device

摘要

A mowing device for the treatment of vegetations is adapted for the attachment to a carrier and for the connection to a drive unit. The mowing device includes a frame, on which mowing spindles are mounted which are provided on one side with mowing blades and on the opposite side with distributing elements for the connection to transmission members. On the frame, a transmission mechanism for driving the mowing spindles is further positioned. The mowing spindles are arranged in two mutually parallel rows, defined by longitudinal lines, located in a mutual distance separation. The mowing spindles of each row are interconnected by the transmission members. The centers of the mowing spindles of the first row on a line are located in a mutual spacing. The centers of the mowing spindles of the second row on the line are located in the mutual spacing. The centers of the mowing spindles of the second row are offset in the direction of the lines by a one-half P/2 of the spacing P with respect to the centers of the mowing spindles of the first row on the line. A connecting line of the center of each mowing spindle of the first row on the line with the center of the immediately adjacent mowing spindle of the second row on the line forms with parallel longitudinal lines an acute angle, for which the following applies: L tg a=P/2 The size of the angle a is in the range from 15° to, 60°. The transmission mechanism for driving the mowing spindles with two transmission devices mounted side by side on the frame and mutually connected. The first transmission device is arranged for the rotation in one rotational direction and is connected via transmission members with the mowing spindles of the first row on the line. The second transmission device is arranged as a reverse device for an optional rotation of the output shaft of the gearbox in both rotational directions, and it is associated via transmission members with the mowing spindles of the second row on the line.

1. A mowing device that is attachable to a carrier and connectable to a drive unit, the mowing device comprising:
(a) a frame; (b) a multiplicity of mowing spindles mounted on the frame and disposed in a plurality of mutually parallel rows, including a first row and a second row, wherein each of the first and second rows comprises a plurality of the mowing spindles, wherein the first and second rows define parallel longitudinal lines separated by a distance L, and wherein each of the plurality of mowing spindles of the first and second rows has a center that is spaced apart from the center of a next adjacent mowing spindle in a same row by a distance P; (c) a transmission mechanism positioned on the frame for driving the multiplicity of mowing spindles, the transmission mechanism comprising first and second transmission devices mounted side by side on the frame and being mutually connected; (d) first transmission means for connecting the first transmission device with the plurality of mowing spindles of the first row; and (e) second transmission means for connecting the second transmission device with the plurality of mowing spindles of the second row; wherein the first transmission device has an output shaft that is rotatable to drive the plurality of mowing spindles of the first row in a first rotational direction and the second transmission device has an output shaft that is rotatable to drive the plurality of mowing spindles of the second row in either the first rotational direction or in a second rotational direction that is reverse to the first rotational direction; wherein each of the plurality of mowing spindles of the first row comprises a mowing blade on a lower side and a distributing element on an upper side for connection to the first transmission means, and each of the plurality of mowing spindles of the second row comprises a mowing blade on a lower side and a distributing element on an upper side for connection to the second transmission means; and wherein the respective centers of the plurality of mowing spindles of the second row are offset from the respective centers of the plurality of mowing spindles of the first row in a direction of the longitudinal lines by a distance P/2 and a line connecting the center of each mowing spindle of the first row with the center of a closest adjacent mowing spindle of the second row forms with the parallel longitudinal lines an acute angle a, which satisfies the following equation:tg⁢⁢α=LP⁢/⁢2 wherein the size of angle α is from 15° to 60°.
