DE960393C - Device for border plowing with mounted reversible plows - Google Patents

Description

The invention relates to a device for border plowing with mounted reversible plows, which with the help sit directly on the tractor using a suitable suspension device. With such plowing could you swivel the ploughshare so far to the right or left that the ploughshare is outside the wheel track worked. It was necessary to use a special head piece for the plow, which is attached to the plow shaft with the help of a joint and is in the correct working position when plowing had to be adjusted. The use of such a special plow head piece and its Articulated storage make the production of the plow more expensive and make it difficult to handle.

These shortcomings are remedied by the invention by inventing the leg a The extension that comes to rest in the direction of travel during border plowing and the carrier for the ploughshare to be turned over.

In order to avoid dismantling and reassembling the plow body when transitioning to border plowing, the plow body can also be carried by a shaft mounted on the plow shaft and by means of a storage to be rotatable about this. There are the most diverse possibilities of fathering as given.

The idea of the invention, which also allows other possible embodiments, is shown in the drawing

reproduced in one embodiment, namely shows

Fig. Ι a plan view of a mounted reversible plow according to the invention,

Fig. 2 the plow according to Fig. Ι in side view and

Fig. 3 is a plan view of another embodiment of the plow.

On the tractor ι is with the help of the usual suspension, for example the three-point hitch 2, the mounted reversible plow hung up. The plow grind 3 sits according to the invention pivotably on the axis 4 on the turning piece 5, which in turn can be pivoted around the turning column 6.

On the plow Leg 3, which in the arrangement of Fig. 1 has at its rear end an angular bend 8, the hull sits g, which each quite applicable in the usual manner at its ends and. left turning

ao ploughshare and mouldboard 10 or io 'carries. By means of the locking screws 11 , the plow body 9, 10, 10 'is held on the plow shaft 3 in an exchangeable and removable manner.

The plow grinder 3 can be pivoted laterally to the right or left about the axis 4. In one or in another position, the plow shaft 3 can be held in place by its adjusting device 12. In Fig. Ι the working position of the plow with right-turning plow body is in solid lines 10 reproduced on the ground. For the purpose of border plowing, after appropriate activity the adjusting device 12 of the plow leg 3 in the position shown in phantom in Fig. 1 be pivoted so that the plow body comes to lie outside the wheel track. The extension 8 of the ploughshare is in the working direction or parallel to it for border plowing to hold the plow body 9, 10, 10 '. The plow body must be placed in the border plowing in the manner shown in phantom in Fig. 1 be what by loosening the clamping device 11 and turning the plow body in such a way that now the left-turning coulter and swivel plate are on the ground, can be done very easily.

The left-turning share and mouldboard 10 'are used for border plowing.

Of course, the arrangement is made so that the plow 3 to both sides is pivotable, so that you can also with the same arrangement and obvious turning the plow body can plow border on the other side of the tractor.

In order to avoid dismantling and reassembling the plow body, one can use the construction of the Also carry out the plow as shown in FIG. Here again sits on the turning column 6 ' Pfluggrindel 3 ', which is equipped with a bend 8' pivotable about the axis 4 'and with Can be determined using the adjusting device 12 'in the respective working position.

The hull carrying the right-turning or left-turning ploughshare and mouldboards 10 and 10 ' is rotatably seated here by means of the bearing 13 on the plow leg part 9'. 14 is the mooring rail for the plow. If there is a transition from normal plowing (extended position) to border plowing (dashed position), it is sufficient if only the plow body with its bearing 13 on the plow shaft part 8 'is rotated by 180 °, which means that instead of the right-turning share and mouldboard 10 now the left-turning share and mouldboard 10 'and vice versa are used. The plow leg extension 8 'assumes the angle α / 2 with respect to the system 14 when α denotes the angle between the normal working position and the limit plow position of the leg. The invention is not limited to the design possibilities of the plow frame shown, nor to the plow system used. It can be used for all types of mounted plows.
