[0027] An adjustment mechanism for controlling ridge spacing includes a main outer beam 3, a main inner beam 4, multiple swing plates 5, side beams 6, and an adjustment and positioning device.

[0028] The main outer beam 3 is a hollow square tube, and multiple long holes 7 are opened along the length direction on both the upper and lower surfaces of the main outer beam 3.

[0029] The inner main beam 4 is a hollow square tube, which is fitted inside the outer main beam 3.

[0030] Multiple side holes 9 of the main inner beam 4 are respectively opened on the left and right surfaces of the main inner beam.

[0031] Each main inner beam has a swing plate 5 inside the side hole 9, and multiple swing plates 5 are located on the left and right sides of the main inner beam 4 respectively.

[0032] Each swing plate 5 has an inner pin shaft 8 on its inner side.

[0033] The inner pin 8 extends through the upper and lower surfaces of the main inner beam 4 at both ends and is set in the corresponding long hole 7 of the main outer beam. The positions of the long hole 7 of the main outer beam and the inner pin 8 are corresponding.

[0034] The swing plate 5 passes through the corresponding side holes 10 of the main outer beam on the left and right surfaces of the main outer beam 4.

[0035] Each swing plate 5 has an outer pin 11 on its outer side.

[0036] Each swing plate 5 passes through the side side hole 12 of the side beam 6 on the corresponding side.

[0037] The outer pin 11 is installed in the pin hole of the side beam 6 on the corresponding side.

[0038] Mounting seats 14 are fixed on the front and rear sides of the main outer beam 3.

[0039] An adjustment and positioning device is provided at one end of the main outer beam 3 and the main inner beam 4.

[0040] The positioning device includes a handle 13 and a bearing 15.

[0041] The handle 13 is supported on the mounting base 14 by the bearing 15, and the end of the handle 13 is threadedly connected to the end hole of the main inner beam 4.

[0042] To ensure more stable operation of the mechanism, a guide support device is installed between the main outer beam 3 and the left and right side beams 6.

[0043] The guide support device includes multiple guide support columns 16.

[0044] Multiple guide support columns 16 (cubic-pole shaped) are fixed on both sides of the main outer beam 3. Guide support column holes with corresponding positions are provided on the side beam 6, and the guide support columns 16 are set in the guide support column holes.

[0045] When the required ridge spacing is narrow, the main outer beam elongated hole 7 and the inner pin shaft 8 can be set in a straight line. (e.g.) Figure 6 (As shown).

[0046] When a wider ridge spacing needs to be adjusted, the main outer beam elongated hole 7 and inner pin shaft 8 can be arranged in two rows on two straight lines to expand the adjustment range. (e.g.) Figure 7 (As shown).

[0047] The working principle is as follows:

[0048] Rotating handle 13 causes the main inner beam 4 to move back and forth, and the inner pin 8 can move back and forth within the long hole 7 of the main outer beam. The swing plate 5 moves within the space of the side holes 9, 10, and 12 of the main inner beam and the main outer beam, forming a linkage mechanism. Adjusting the position of the main inner beam 4 causes the swing plate 5 to extend or retract left and right, pushing or retracting the corresponding side beam 6. The side beam 6 moves along the left and right width direction of the guide support column 16, causing the tillage wheels 1 on the left and right side beams 6 to change their width to adapt to different ridge spacing. Two mounting seats 14 are fixed to the no-tiller, supporting the mechanism, allowing the mechanism to adjust its width left and right as needed.
