Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a center drive rotary in which the direction of rotation of a tiller can be switched between forward and reverse by changing the connection direction of the center drive rotary portion to the tractor back and forth.

Conventional center drive rotaries have an input shaft installed in only one direction, so to rotate the tiller in the forward and reverse directions, the tiller must be completely reversed and installed, or a forward/reverse switching device T is installed in the drive unit. The work is quite difficult, takes a long time, and costs are high.

Therefore, in the present invention, the gear case provided on the upper part of the drive case that pivotally supports the cultivator has front and rear input wheels that are respectively supported by metal shafts, and these input shafts are mutually supported by a gear mechanism in the gear case. formed to rotate in the opposite direction,
Moreover, these input shafts are arranged so that the intersecting angles made with respect to the center line of the drive case are approximately equal to each other, so that each of these input shafts can be connected to the towing machine so that it can be positioned at the rear of the towing machine. The tiller can be rotated in either the forward or reverse direction simply by connecting the input shaft to the rear of either the front or rear input shaft tf of the rotary.

Therefore, in FIG. 1, (1

It is necessary to incline at an approximately equal inclination angle with respect to U).

The degree of power (Oh) should be approximately equal to the degree of power (Oh). Therefore, as shown in Fig. 1, the rotation 1111 (119 and rotor 1) of the traction machine (I8) is fully connected to the input shaft (4M) in front of the rotor 1, and in this case it becomes IE rotation and the tilling body;

Furthermore, in order to attach the drive case +2]' to the towing tea0 groan, fully secure the drive case (+1) to the center of the top of the drive case (+1), and align the center line of the drive case +21 ((J-0 ) with a mounting hole mat- provided on the extension line of

Also, the lift arm, which is pivotally supported at one end on the traction shaft, is connected to the lower link via a link.

A gear case (8) is provided on the upper part of the drive case which pivotally supports the tiller, and the gear case (8) has input shafts (4a x 4b) in the front and rear, respectively. ) These input shafts (
4) (Xian) t'' are formed to rotate in opposite directions,
In addition, the input shafts (4*) and (4b) are provided in such a way that the angles of deflection made with respect to the center line of the drive case (2) are equal, so that each of these human power shafts can be positioned at the rear of the traction machine A4. Since it is configured so that it can be connected to the rotary (1) for traction (41!4 nq), the direction of rotation of the tiller 11 scales can be switched to full forward rotation or reverse by changing the connection direction of the rotary (1) for one jet. This can be done extremely easily by a simple operation such as changing the direction.Furthermore, even if the direction is changed, the inclination angle of the drive case (2) with respect to the direction of movement of the rotary (1) will always be Since it is constant and does not change, there is also the advantage that the tillage operation can always be carried out in a suitable condition.
