[0059] Embodiment 2:

[0060] On the basis of the above embodiment 1, the ridging unit comprises:

[0061] Support plates 11, two support plates 11 are slidably connected in the box body 1 and extend out of the bottom opening of the box body 1, and the soil ridge plate 2 is connected to the opposite sides of the two support plates 11 through a rotating shaft;

[0062] A limit slider 12, the limit slider 12 is connected to the front and rear sides of the support plate 11, and the inner wall of the box body 1 is provided with a horizontal slide groove adapted to the limit slider 12;

[0063] The sleeve 13 and the slide bar 14 are respectively connected to opposite sides of the two support plates 11 , and the slide bar 14 is slidably connected in the sleeve 13 .

[0064] The working principle and beneficial effects of the above technical solution are:

[0065] When the ridge forming unit is in use, the ridge disc 2 is connected to the box body 1 through the support plate 11, the top ends of the two support plates 11 are arranged in the box body 1, and the limit slider 12 slides along the horizontal slide groove, so that the two support plates 11 always slide in the horizontal direction, that is, the sliding direction of the ridge disc 2 is controlled, and they can only approach or move away from each other in the horizontal direction; when the spacing between the two ridge discs 2 is adjusted, the slide bar 14 slides in the sleeve 13, and the slide bar 14 and the sleeve 13 are arranged in the lower middle part of the support plate 11, and the lower middle part of the two support plates 11 is limited and guided, so as to further improve the adjustment accuracy of the ridge disc 2, reduce the deformation of the support plate 11 under the soil pressure during the ridge operation, and ensure the accuracy of the ridge spacing.

[0066] Embodiment 3:

[0067] On the basis of the above-mentioned embodiment 2, the dynamic adjustment unit includes a spacing adjustment module, and the spacing adjustment module includes:

[0068] A hydraulic cylinder 21, which is vertically mounted on the top of the box body 1, with the rod of the hydraulic cylinder 21 extending into the box body 1, and the bottom of the rod is connected to an adjusting pressure block 22;

[0069] A guide rod 23, the guide rod 23 is slidably connected to the top of the box body 1, and the bottom end of the guide rod 23 is connected to the adjustment block 22;

[0070] A frame assembly, the frame assembly is connected to the bottom end of the adjusting pressing block 22;

[0071] Rocker assembly, the two rocker assemblies are rotatably connected to the bottom end of the frame assembly, and the bottom ends of the two rocker assemblies are respectively connected to the two support plates 11.

[0072] The working principle and beneficial effects of the above technical solution are:

[0073] When the dynamic adjustment unit is used, the hydraulic cylinder 21 of the spacing adjustment module is started. The hydraulic cylinder 21 is arranged vertically and its rod can move in the vertical direction. When the rod of the hydraulic cylinder 21 extends downward, it pushes the adjustment block 22 to move downward. The rocker assemblies on both sides of the adjustment block 22 rotate and expand to both sides after being compressed, so that the spacing between the two soil ridge discs 2 increases; on the contrary, when the rod of the hydraulic cylinder 21 is retracted upward, it drives the adjustment block 22 to move upward. The adjustment block 22 drives the rocker assemblies on both sides to rotate inward, so that the spacing between the two soil ridge discs 22 decreases. The guide rod 23 moves synchronously with the adjustment block 22 and slides relative to the top of the box body 1, guiding the movement of the adjustment block 22. Through the above structural design, the spacing between the two soil ridge discs 2 can be quickly adjusted. The hydraulic cylinder 21 is used as a power source to provide stable power to prevent the soil ridge disc 2 from shifting during the soil ridge process.

[0074] Embodiment 4:

[0075] Based on the above embodiment 3, the framework component includes:

[0076] The screw sleeve 24 is connected to the bottom end of the adjusting pressure block 22 and is connected to the bottom end of the rod of the hydraulic cylinder 21;

[0078] The second frame 26 is provided with two and respectively connected to the two ear plates of the first frame 25 . The second frame 26 is provided with a U-shaped frame and provided with two left and right ear plates. The rocker assembly is rotatably connected to the second frame 26 .

[0079] The working principle and beneficial effects of the above technical solution are:

[0080] A screw sleeve 24 is provided on the top of the frame assembly, which is threadedly connected to the rod of the hydraulic cylinder 21 through the screw sleeve 24, thereby ensuring the stability of the connection and facilitating disassembly and assembly when the hydraulic cylinder 21 is in action; the first frame 25 is connected under the screw sleeve 24, and two ear plates are provided at the front and rear, respectively used to fix the front and rear second frames 26, and the second frame 26 is provided with two ear plates on the left and right, respectively used to fix the left and right rocker assemblies.

[0081] Embodiment 5:

[0082] On the basis of the above-mentioned embodiment 4, the rocker assembly comprises:

[0083] A first rocker 27, the first rocker 27 is hinged to the top of the ear plate of the second frame 26, and the front and rear first rockers 27 are connected by a hinge shaft;

[0084] A second rocker 28, the second rocker 28 is hinged to the bottom end of the ear plate of the second frame 26, and the second rocker 28 is arranged in parallel with the first rocker 27, and the front and rear second rockers 28 are connected by a hinge shaft;

[0085] The pressing frame 29 is hinged with the two front and rear first rocking arms 27 and the two front and rear second rocking arms 28 at the same time. The pressing frame 29, the first rocking arms 27, the second rocking arms 28 and the second frame 26 form a double rocking arm mechanism; the pressing frame 29 is connected to the support plate 11.

[0086] The working principle and beneficial effects of the above technical solution are:

[0087] The rocker assembly includes a first rocker 27 and a second rocker 28 which are arranged up and down. The pressing frame 29, the first rocker 27, the second rocker 28 and the second frame 26 form a double rocker mechanism. The lengths of the first rocker 27 and the second rocker 28 are equal, so that the pressing frame 29 always maintains a vertical downward state during movement; the first rocker 27 and the second rocker 28 fix the upper and lower parts of the pressing frame 29 respectively, so as to maintain the stability of the pressing frame 29 during the movement process, thereby stably pushing the support plate 11 to move.

[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] The first spring 31 is sleeved on the outside of the screw sleeve 24 and the first frame 25. The top end of the first spring 31 is connected to the adjusting pressure block 22, and the bottom end is crimped on the first rocker 27. The first spring 31 is configured as a conical spring, and the bottom diameter of the first spring 31 is larger than the top diameter.

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

[0092] When the spacing is being adjusted, as the rod of the hydraulic cylinder 21 moves downward, the adjusting block 22 is pushed downward, and the rocker assemblies on both sides of the adjusting block 22 rotate and expand to both sides after being compressed, that is, the first rocker 27 and the second rocker 28 expand to both sides, and the first rocker 27 applies pressure to the first spring 31 to compress the first spring 31. As the compression amount of the first spring 31 increases, the resistance to the expansion of the rocker assembly increases. On the contrary, 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, and the pressure of the first rocker 27 on the first spring 31 is reduced, so that the first spring 31 gradually extends until it is reset. Through the above-mentioned structural design, the setting of the first spring 31 can gradually increase the resistance to the expansion of the two rocking arms as the expansion degree of the two rocking arms increases, so that the two rocking arms are always kept in a compressed state, which on the one hand helps to eliminate the transmission gap and improve the adjustment accuracy of the spacing between the two ridge discs 2; on the other hand, the elastic force acts on the first rocking arm 27 to play a shock-absorbing role, dissipating the vibration wave transmitted by the ridge disc 2 during the ridge operation, reducing the structural shaking and ensuring the ridge-forming effect; on the other hand, as the spacing between the two ridge discs 2 increases, the soil pressure acting on the ridge disc 2 also increases. During the operation, the possibility of the ridge disc 2 being squeezed and deformed by the soil also increases. By dynamically adjusting the expansion resistance between the two rocking arms, when the spacing between the two ridge discs 2 increases, the movement resistance also increases, thereby enabling the ridge disc 1 to adapt to different ridge spacings and improving the stability of the ridge-forming device.

[0093] Embodiment 7:

[0094] Based on the above embodiment 6, the friction resistance adjustment module further includes:

[0095] A support frame 32, the support frame 32 is connected to the bottom end of the pressing frame 29;

[0096] The friction wheel 33 is rotatably connected to the support frame 32, and support shafts 34 are provided at both ends of the friction wheel 33; an arc groove adapted to the friction wheel 33 is provided at the top of the support plate 11, and the support plate 11 moves synchronously with the friction wheel 33;

[0097] The guide rail 35 is horizontally arranged in the box body 1, and the friction wheel 33 is rollingly arranged on the guide rail 35. The width of the friction wheel 33 is greater than the width of the guide rail 35. The top of the support plate 11 is provided with an avoidance groove 36 for the guide rail 35 to pass through;

[0098] Support blocks 37, two support blocks 37 are slidably connected to both sides of the support frame 32, a spring groove 38 is provided at the top of the support block 37, a column 39 is penetrated in the spring groove 38, guide grooves 41 are symmetrically provided on both sides of the support frame 32, and the ends of the column 39 are slidably provided in the guide grooves 41; an arc groove 42 is provided at the bottom of the support block 37, and the arc groove 42 is pressed on the top of the support shaft 34;

[0099] The friction strip 43 is connected between the two support blocks 37 . A friction surface is provided at the bottom end of the friction strip 43 , and the friction surface contacts the friction wheel 33 .

[0100] The working principle and beneficial effects of the above technical solution are:

[0101] When the friction resistance adjustment module is in use, the friction wheel 33 is installed on the support frame 32 through the support shafts 34 on both sides. The friction wheel 33 rolls along the upper surface of the guide rail 35, guiding the movement of the support plate 11 and providing a fulcrum for the deployment of the rocker assembly to ensure the stability of the spacing adjustment process; the support block 37 is crimped on top of the support shaft 34, and a friction strip 43 is arranged between the two support blocks 37. The friction surface of the friction strip 43 contacts the friction wheel 33, which can increase the resistance of the friction wheel 33 when it rotates.

[0102] Embodiment 8:

[0103] Based on the above embodiment 7, the friction resistance adjustment module further includes:

[0104] The second spring 44 is sleeved on the outside of the pressure frame 29 and the support frame 32. The bottom end of the second spring 33 is connected to the spring groove 38, and the top end is crimped onto the second rocker 28. The second spring 44 is configured as a conical spring, and the top diameter of the second spring 44 is larger than its bottom diameter.

[0105] The working principle and beneficial effects of the above technical solution are:

[0106] A second spring 44 is arranged between the second rocker 28 and the support block 37. When the rocker assembly is in the initial state, the second rocker 28 has a small expansion range, and the pressure on the second spring 44 is small. The second spring 44 is installed in the spring groove 38 of the support block 37, that is, the pressure on the support block 37 is small, and the support block 37 can slide along the outer side of the support frame 32. The column 39 slides in the guide groove 41 to guide the support block 37. At this time, there is no contact between the friction strip 43 and the friction wheel 33 or the contact pressure is small, which has little effect on the expansion of the rocker assembly, making the adjustment process more flexible. When the rocker assembly is expanded to a preset angle, the second rocker 28 compresses the second spring 44, so that its bottom end pushes the support block 37 to move to the lowest point, the arc groove 42 is pressed against the support shaft 34, and the friction strip 43 between the two support blocks 37 is in close contact with the friction wheel 33 and maintains a certain pressure, thereby increasing the resistance of the friction wheel 33 during rotation. Through the above-mentioned structural design, on the one hand, when the ridge disc 2 is adjusted in a small range, the influence on the deployment of the rocker assembly is reduced, making the adjustment process more flexible; on the other hand, after the rocker assembly is deployed to a preset angle, the friction resistance of the friction wheel 33 is adjusted, and the friction resistance increases with the increase of the spacing between the ridge discs 2, so that after the friction wheel 33 is adjusted to the preset position, it is not easy to shift under the action of soil pressure, thereby realizing the dynamic adjustment of the friction resistance on the friction wheel 33; on the other hand, the support block 37 and the support frame 32 slide within a preset range in the vertical direction. When passing through an uneven road section, the vibration received by the ridge disc 2 can be dissipated by the second spring 44, and at the same time, the support block 37 vibrates slightly up and down to improve the shock absorption effect, and returns to the original crimping state after shaking, so that the friction strip 43 keeps in contact with the friction wheel 33.
