Rotary rake

The invention relates to a rotary rake according to the generic term of patent claim 1. This is derived from DE-OS 41 03 507 and the not yet published patent application P 44 36 388.5.

The object of the invention is to be able to use the possible working width of a swather equipped with at least three staggered swath rotors at low cost while simultaneously providing a wide range of functions and, above all, high area performance. With the known arrangements of staggered swath rotors, this was only possible to a lesser extent.

The solution to the problem is seen in the proposal according to the characterizing part of claim 1 and in further development with the teaching of the subclaims.

The invention is explained by way of example using the drawing - always viewed as a schematic plan view of a machine according to the invention. It shows:

Fig. 1 the swather according to the invention with three swath rotors in working position for forming a centrally deposited large swath,

Fig. 2 the swather according to Fig. 1 with the rear left swath rotor in the resting position for depositing a side swath,

Fig. 3 the swather according to Fig. 1 with the front swath rotor in rest position for central swath deposition,

Fig. 4 the swather according to Fig. 1 with the rear left swath rotor in the resting position and the wheels tilted to form two smaller swaths

Fig. 5 the swather according to Fig. 1 with all three swath rotors in working position and inclined wheels to form two swaths of different sizes

Fig. 6 the swather according to Fig. 1 with all three swath rotors in working position, obliquely angled running wheels and the same direction of rotation of the two rear swath rotors to form three smaller swaths

Fig. 7 a towed swather with four pairs of counter-rotating swath rotors to form an oversized central swath, and

Fig. 8 a tractor with swath rotors arranged in pairs at the front and rear.

(1) designates the chassis of a towed rotary swather, which consists of a longitudinal beam (2) that also forms the drawbar, a running axle (3) and two directionally adjustable running wheels (4). Brackets (5, 6, 7, 8) are rigidly attached to the longitudinal beam (2), in which support arms (9, 10, 11, 12) are pivotably mounted via pivot axes (13, 14, 15, 16) that run parallel to the beam (2) (via adjustment means not shown). Driven swath rotors (17, 18, 19, 20) are attached to the free ends of the support arms, the direction of rotation of which can be changed according to the arrow directions indicated. The swath rotors are supported on a chassis with two support wheels (22). The support wheels (22) can be designed as trailing wheels for better cornering of the machine. Instead of a two-wheeled chassis, the swath rotors can also be supported on a known four-wheeled tandem chassis (23) with trailing wheels (Fig. 8).

Claims (1)

.4. SAYINGS 01. Rotary swather with three swath rotors driven to rotate around approximately vertical axes to form a large swath deposited centrally between two swath rotors or several small swaths deposited to the side of a swath rotor, whereby - viewed in the direction of travel - a third swath rotor is assigned in a staggered manner to two swath rotors arranged next to one another in pairs and whereby the individual swath rotors can be brought out of the working position by swiveling them up and are attached to a towed or self-propelled chassis, characterized in that the third swath rotor (19) is arranged in front of the swath rotors (17, 18) arranged next to one another in pairs, projecting out to the side, in the direction of travel. 02. Rotary swather according to claim 1, characterized in that a fourth swath rotor is arranged sideways and approximately equally projecting to the third swath rotor (19). 03. Rotary rake according to claims 1 and 2, in a towed design with a chassis having running wheels, characterized in that the running wheels (4) are directionally adjustable in a known manner. 04. Rotary swather according to claims 1-3, characterized in that the swath rotors (17, 18, 19, 20) are reversible in their direction of rotation in a known manner. -5- -5- 05. Rotary swather according to one or more of claims 1, 2 and 4, characterized in that the chassis for the rotary swathers (17, 18, 19, 20) is a tractor (21), to the front and rear of which the rotary swathers (17, 18, 19, 20) are attached.
