Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tractor-mounted ridge ratchet which can be turned in a direction opposite to the steering direction of a tractor.

(Prior Art) Generally, a rotary tiller is connected to the tractor body through a six-point linkage mechanism? Installation 12. The undulation device is attached to a mounting frame that protrudes rearward from this M turning machine.

The tiller is set with a check chain so that it cannot swing from side to side with respect to the tractor body, and the furrow device is in charge of upper flt adjustment with respect to the mounting frame, but the column is immovable.
The center line of the ridge is always on or parallel to the center line of the tractor body.

(Problem to be solved by the invention) In the technique of deleting and following, when the tractor r left and right Vc is operated,
Even though the tiller and ridge riser are swung left and right and the travel trajectory is curved, the center line of the ridge riser remains aligned with the center line of the tractor body, and the ridges are in a normal shape. It is difficult to form along the travel trajectory.

(Means for Solving the Problems) The present invention has a ridge riser connected to a tractor vehicle body (51) that rotates about a vertical axis, and this ridge riser F581 is the first operating member of the steering mechanism. Almost linked with 17, inspection-&11
By providing an interlocking mechanism 14 that moves the vehicle forward in a direction opposite to the steering direction of the vehicle, the problems of the prior art described above can be solved.

In other words, the specific structure of the problem solving means in the Kihatsu F3Avc is characterized by the fact that the ridge riser cup support (591) is attached to the mounting frame 61 attached to the tractor body 15)
The column 1591 is attached to the column 1591 so that it can rotate freely around the vertical axis, and between the column 59+ and the operating member (between the tractor steering mechanism). Mechanism 133I is of course at point t.

(For use) When the tractor (1) is steered in one direction to follow the curved cultivated land or to turn around the headland, the steering field: Moving member (to) The interlocking mechanism 1331 is actuated by the front movement [7, column 69 of the furrow device β&] to rotate in a direction opposite to the steering direction of steering @(2) 11. Therefore, the center line of the ridge (FJ is changed from the state along the center M (GJ) of the tractor body (6), and the traveling trajectory of the tractor fi+ (almost along the gun) becomes the same.

1IJE continuous # mechanism - At 33 degrees, the pitman arm, which is rotated by the steering wheel, rotates the control lever [4al] and controls the control valve: 461 to reverse the steering direction of the steering wheels. 17 pillars! Operate the hydraulic cylinder so that IIF1'''r.

In each of the above embodiments, power steering may be used for the steering machine 'a 30+, and the first link example and the link decoy may be connected to the middle of the pitman arm (2) or to the drag link aid. The secondary interlocking mechanism ellipse 33' electrically detects the steering direction and steering angle of the two handles (24J), controls the control valve 1 with the detection signal, and activates the hydraulic cylinder (6u) that pushes and pulls the arm (6u). 47I as f′
r: It is also possible to configure the steering wheel to move, and various types of steering operation member and its operation detection means are conceivable. The ridge stand (581) may be directly attached to the six-point linkage mechanism via a mounting frame.

When the tractor +11 turns around the headland of the field or runs on the curved cultivated land, the ridge mechanism is the fifth one.
As shown in the figure, by the operation of the interlocking mechanism panel, the center of the ridge mechanism, t#! (FJ rotates from the center line (Gl) of the tractor body (5) in the opposite direction to the steering direction, and the tractor +
The traveling trajectory of l+ (the posture is approximately in line with the tangent to El).

The ridge formed will be closer to a regular 18-shaped shape than if it were along the center i (Gl).

(Effects of the Invention) According to the present invention described in detail above, the ridge support column (59
) is rotatable around the vertical axis, and an interlocking mechanism S3 is provided between this support column 159) and the first operating member of the steering mechanism, and this interlocking mechanism C13 substantially interlocks with the operating member to steer the support column 159). Since it is configured to rotate in the opposite direction to the VC, the center line (F) of the ridge erector can be roughly aligned with the tractor (110 travel trajectory (EJ), even if the field is deformed. Also, even on headlands, it is possible to create ridges of normal shape, and the ridges have a good finish (!-).
