[0088] Embodiment 6:

[0089] On the basis of the above-mentioned embodiment 5, the dynamic adjustment unit further includes a friction resistance adjustment module, and the friction resistance adjustment module includes:

[0090] First spring 31, first spring 31 is sleeved on the outer side of the screw sleeve 24 and the first frame 25, the top end of the first spring 31 is connected with the adjusting block 22, and the bottom end is pressed on the first rocker 27; the first spring 31 is arranged as a conical spring, and the diameter of the bottom of the first spring 31 is larger than that of the top.

[0091] The working principle and beneficial effects of the above technical scheme are:

[0092] When the distance is adjusted, as the rod of the hydraulic cylinder 21 moves downward, the adjusting block 22 is pushed to move downward, and the rocker assemblies on both sides of the adjusting block 22 are pressed to rotate and expand to both sides, i.e. the first rocker 27 and the second rocker 28 expand to both sides, the first rocker 27 exerts pressure on the first spring 31 to compress the first spring 31, and as the compression amount of the first spring 31 increases, the resistance of the rocker assemblies to expand increases. Conversely, as the rod of the hydraulic cylinder 21 moves upward, the adjusting block 22 is driven to move upward, and the rocker assemblies on both sides rotate inward, the pressure of the first rocker 27 on the first spring 31 decreases, and the first spring 31 gradually elongates until it returns to its original position. Through the above structural design, the first spring 31 is arranged to gradually increase the resistance to the expansion of the two rockers as the degree of expansion of the two rockers increases, so that the two rockers always remain in a compressed state. On the one hand, it helps to eliminate the transmission gap and improve the distance adjustment accuracy of the two ridge soil plates 2; on the other hand, the elastic force acting on the first rocker 27 plays a damping role, dissipates the vibration waves transmitted by the ridge soil plates 2 during ridge soil operation, reduces the structural vibration, and ensures the ridge forming effect; on the other hand, as the distance between the two ridge soil plates 2 increases, the soil pressure acting on the ridge soil plates 2 also increases, and the possibility of deformation of the ridge soil plates 2 due to soil extrusion also increases during operation. Through dynamic adjustment of the expansion resistance between the two rockers, the moving resistance also increases as the distance between the two ridge soil plates 2 increases, thereby enabling the ridge soil plates 1 to adapt to different ridge distances and improving the stability of the ridge forming device.

When the rocker assembly is unfolded to a preset angle, the second rocker 28 compresses the second spring 44, so that the bottom end of the second spring 44 pushes the support block 37 to move to the lowest position, the arc-shaped groove 42 is in pressure connection with the support shaft 34, the friction pressing strip 43 between the two support blocks 37 is in close contact with the friction wheel 33 and maintains a certain pressure, and the resistance of the friction wheel 33 during rotation is increased. Through the above structural design, on the one hand, when the ridge soil disc 2 is adjusted in a small range, the influence on the unfolding of the rocker assembly is reduced, so that the adjustment process is more flexible; on the other hand, when the rocker assembly is unfolded to a preset angle, the friction resistance of the friction wheel 33 is adjusted, and the friction resistance increases with the increase of the distance between the ridge soil discs 2, so that the friction wheel 33 is not easy to move after being adjusted to a preset position under the action of soil pressure, and the dynamic adjustment of the friction resistance of the friction wheel 33 is realized; on the other hand, the support block 37 and the support frame 32 slide in a preset range in the vertical direction, when passing through a bumpy road section, the vibration of the ridge soil disc 2 can be dissipated through the second spring 44, and the support block 37 is slightly shaken up and down, the shock absorption effect is improved, and the friction pressing strip 43 and the friction wheel 33 are kept in contact after the shaking.
