Description

Double-barbed mounted or semi-mounted mowers are known, in which the cutting apparatus has a self-contained attachment or one of the cutting apparatus is made frontal. This greatly complicates the installation of the mower on a tractor or self-propelled maccii.

In the proposed device, the cutting apparatus, located on the side, is pivotally attached to a common nylon frame, which is illuminated to the tractor by means of quick couplings, which greatly facilitates the installation of the mower. The use of an active rotary lifter driven by a support wheel of the frame and design of a traction fuse designed to operate at constant force, regardless of where it is applied to the finger bar, improves its operation.

FIG. 1 shows a diagram of the mower (top view); in fig. 2-diagram of the rotary lifter; in fig. 3 is a diagram of the mechanism for raising the finger bar and in FIG. 4-diagram of the device for traction fuse.

The mower consists of a semi-mounted frame / attached to the trailer by two quick-release couplings made in the form of pins and 5 with a free fit. One point of the frame is attached to the hook-on bracket 4 of the tractor, and the second point to the special bracket 5 attached to the spars 6 of the tractor. The third point of support is the wheel 7 at the outer end of the frame. The cutting units 8 are pivotally attached to the frame. The knives of the cutting units are driven from the power take-off shaft 9 through a chain drive 10 to the intermediate shaft 11 and from it using wedge-mounted gears 2 and 13 to the shafts 14 and 15, which carry the eccentrics 16 and 17 on the front ends.

To improve the quality of work and lift the laid grass, kneaded by the front bar of the mower, on the hub of the support wheel

No. 135715-2rams, an active rotary type lifter is assembled, consisting of a shaft 18, on the upper end of which figure fingers 19 are fixed. The elevator is driven from hub 20 through a pair of bevel gears 21 and 22.

In order to protect against breakdowns when hitting cutters on an insurmountable obstacle, the mower is equipped with a traction fuse designed to operate under constant force regardless of where it is applied to the finger bar. The fuse consists of a spring-loaded wedge 23, the end of which enters the socket of the hinge bracket 24; the force of the spring 25 is adjusted by means of a cap nut 26.

The lifting of the cutting units is carried out by external cylinders 21 and 28 operating from the tractor hydraulic system. The rear hydraulic cylinder is shariirno mounted on the mower frame, and the piston rod 29 is pivotally connected to the triangular lever 30, which is also hinged on the frame. To the third end of the lever is fixed m ha 31 lifting the cutting unit.

Subject invention

Claims (3)

1. A two-mowed half-mower mower with a one-sided side arrangement of the cutting units, with the use of remote hydraulic tools to lift finger bars, characterized in that its hinged frame, in order to facilitate and accelerate the connection to the tractor, is equipped with two quick-release connections, made in the form of pins free landing, and resting on the extension wheel, which is the third point of support. 2. The mower according to claim 1, from licha and y with the fact that, in order to lift the band of laid grass, remaining after the passage of the front bar shoe, it uses an active rotary lifter with figured fingers mounted on the outboard support hub wheel frame driven by it. 3. The mower according to claim 1, characterized in that, in order to operate the traction fuse with the same magnitude of the obstacle reaction regardless of the point of application of this reaction along the length of the cutting apparatuses, the fuse is designed as a spring-loaded adjustable wedge entering the slot trailed earrings frame mowers.
