転入力軸にカバーを被せておくとよい。An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a gear box provided in the front part of the main body of the rotary tiller, and in the gear box 1, the first input shaft 2 and the second input shaft 2 are parallel to each other and the tip end side is a gear. The second input shaft 3 protrudes forward from the box 1 and is shorter than the first input shaft 2 in the gear box 1. The output shaft 4 is axially supported so as to be orthogonal to the first and second input shafts 2 and 3, and one end of the output shaft 4 passes through the front side of the tip of the second input shaft 3 and comes close to the first input shaft 2. It is extended. A large-diameter bevel gear 5 for driving is fixed to an end portion of the first input shaft 2 in the gear box 1, and a small-diameter gear 6 for driving is fixed to an end portion of the second input shaft 3 in the gear box 1. Has been done. Then, in the portion of the output shaft 4 inside the gear box 1, a driven small-diameter bevel gear 7 that meshes with the large-diameter bevel gear 5 and a driven large-diameter bevel gear 8 that meshes with the small-diameter bevel gear 6 are provided. It is fixed. Behind the input shaft 4, parallel to this, the rotary shaft 9
Is mounted, and a chain transmission system (10) is provided between the side end portion of the output shaft 4 and the side end portion of the rotary shaft 9 so that power is transmitted from the output shaft 4 to the rotary shaft 9. It is like this. The rotary shaft 9 is provided with a plowing / mowing blade (not shown) for performing plowing work during normal rotation and mowing work during reverse rotation. On the other hand, rotational power is selectively transmitted from the PTO shaft of a tractor (not shown) to the first and second input shafts 2 and 3 via a universal joint and a transmission shaft. The large-diameter bevel gears 5 and 8 have 35 teeth, the small-diameter bevel gear 6 has 13 teeth, and the small-diameter gear 7 has 16 teeth.
The number of teeth on both sprocket wheels of a single chain transmission
In the case of four sheets (that is, one-to-one) and the input rotation speed to the first or second input shaft is 540 rpm, the rotary shaft 9
The rotation speed of is as follows. (When inputting to the first input shaft 2) 540 × 35/16 × 14/14 = 1181 rpm (reverse rotation) (When inputting to the second input shaft 3) 540 × 13/35 × 14/14 = 200 rpm (forward rotation) ) Therefore, normal rotation tilling work of 200 rpm, 1181 rpm
It will be possible to selectively perform the reverse mowing work. Also,
The distance between the first input shaft 2 and the second input shaft 3 can be appropriately set by changing the distance l between the small diameter bevel gear 7 and the large diameter bevel gear 8 as shown in FIG. In the forward / reverse tilling apparatus having such a structure, when performing the tilling operation, the forward rotation tilling operation at 200 rpm can be performed only by connecting the power from the tractor to the second input shaft 3. In addition, the power from the tractor should be
Reverse connection mowing work of 1181 rpm can be performed only by connecting to the input shaft 2. In order to change the rotation speed of the rotary shaft 9, the input shaft 2,
3 or the number of teeth of the bevel gears 5-8 may be changed. Also, when inputting to the first input shaft 2, the second
When the input shaft 3 is inputting to the second input shaft 3, both the first input shaft 2 and the first input shaft 2 are idling. Therefore, it is preferable to cover these idling input shafts.

軽量化が図れ、コストダウンが達成される。As described above, according to the forward and reverse cultivating apparatus of the present invention, the driving gears 5 and 6 are respectively attached to the two input shafts 2 and 3.
Since the output shaft 4 is provided with driven gears 7 and 8 that mesh with the gears 5 and 6, respectively, the output shaft 4 outputs forward and reverse rotations having different rotational speeds to perform up-cut and down-cut. Both the cutting work can be easily done by selecting the input to the two input shafts. In addition, since power transmission and gear shifting are performed with a minimum number of gear meshes, the gear box that houses these gears can be made small, which simplifies and downsizes the mechanism while also reducing weight, achieving cost reduction. To be done.
