[0002] The existing rotary reclamation, ridging, fertilizing and rolling integrated equipment has the following aspects that need to be improved: 1. During the ridging process, it is not convenient to adjust the height of the ridging mechanism. The consistency of the ridge height and the consistency of the furrow depend relatively on the flatness of the land. When encountering terrains such as slopes and pits, the forming condition of the ridge will be affected; 2. During the ridging process, the equipment is prone to swing left and right, affecting the ridging effect; 3. The rolling mechanisms of the equipment are mostly in the forms of compaction rollers, compaction plates, etc. During the ridging process, the rolling mechanism is not convenient to adjust in real time, and during the rolling process, it cannot be adaptively adjusted according to the actual situation of the field. When encountering terrains such as slopes and pits, the rolling mechanism cannot fully roll the ridge and may even damage the ridge.

The ridging adjustment mechanism 6 includes a fixed support arm 61, a swing support arm 62, a telescopic driving member 63 and a limiting wheel 64. The fixed support arm 61 is connected to the frame 1 and the fixed support arm 61 is located at the rear end of the frame 1. A swing arm connection part and a driving connection part are provided on the fixed support arm 61. The swing support arm 62 is connected to the swing arm connection part of the fixed support arm 61 and the swing support arm 62 can rotate relative to the fixed support arm 61. The telescopic driving member 63 is arranged at the driving connection part and can rotate relative to the driving connection part. The telescopic part of the telescopic driving member 63 is connected to the swing support arm 62 and the telescopic driving member 63 can rotate relative to the swing support arm 62. The telescopic driving member 63 can drive the swing support arm 62 to rotate around the fixed support arm 61 by telescoping. A limiting wheel 64 is provided on the swing support arm 62.

[0027] During the ridging process, the limiting wheel 64 supports on the ground and rotates as the frame 1 moves forward. When the telescopic driving member 63 extends, it can drive the swing support arm 62 to swing downward, thereby driving the frame 1 to lift. When the telescopic driving member 63 shortens, it can drive the swing support arm 62 to swing upward, thereby driving the frame 1 to lower.

[0028] In some embodiments, as a specific example, the swing arm connecting portion and the driving connecting portion are provided with connecting pins. The swing support arm 62 is rotatably connected to the swing arm connecting portion through a connecting pin, and the telescopic driving member 63 is also rotatably connected to the driving connecting portion through a connecting pin.

The opposite side end faces of the first soil dividing plate 31 and the second soil dividing plate 32 are soil dividing end faces, and both of their soil dividing end faces are inclined forward of the frame 1. When the towing vehicle drives the frame 1 to move forward, the first soil dividing plate 31 and the second soil dividing plate 32 gather the soil between them towards the middle to form ridges. The area between the first soil dividing plate 31 and the second soil dividing plate 32 is set as the ridging area, and the ridges are formed in the ridging area when the towing vehicle drives the frame 1 to move forward.

[0033] At least two of the ridging mechanisms 3 are arranged along the width direction of the frame 1. The arrangement direction of the ridging mechanisms 3 is perpendicular to the forward direction of the towing vehicle driving the frame 1. In the width direction of the frame 1, the area between adjacent ridging mechanisms 3 is set as the furrow area. After the ridging mechanisms 3 ridge in the ridging area, furrows are formed in each furrow area.

[0034] In order to avoid damaging the ridges, the limit wheels 64 of each ridging adjustment mechanism 6 are all located in the furrow area, and the limit wheels 64 are behind each ridging mechanism 3 and travel along the furrows.

[0035] In some embodiments, in order to avoid a large amount of soil accumulation at each ridging area, the first soil dividing plate 31 and the second soil dividing plate 32 are offset in the front-rear direction. The first soil dividing plate 31 and the second soil dividing plate 32 are offset and cooperate with each other to make the soil gather in the ridging area and form ridges. Soil dividing hooks are arranged at the front ends of both the first soil dividing plate 31 and the second soil dividing plate 32. The soil dividing hooks break up the soil at the front ends of the first soil dividing plate 31 or the second soil dividing plate 32 to facilitate the gathering of soil by the first soil dividing plate 31 and the second soil dividing plate 32 towards the ridging area.

[0036] Corresponding to each ridging area on the frame 1, a pressing mechanism 4 is arranged. The pressing mechanism 4 is used to press the formed ridges.

[0037] In a further embodiment, soil dividing hook mounting members are provided on the frame 1 corresponding to each soil dividing hook, and the soil dividing hook is connected to the frame 1 through the soil dividing hook mounting member. A number of soil dividing hook mounting holes are provided on the soil dividing hook mounting member, and the soil dividing hook mounting holes are distributed vertically. A soil dividing hook through hole is provided on the soil dividing hook, and the soil dividing hook is mounted on the soil dividing hook mounting member by bolts passing through the soil dividing hook mounting holes and the soil dividing hook through holes. The design of multiple soil dividing hook mounting holes enables the mounting height of the soil dividing hook to be adjustable.

[0038] In some embodiments, the fixed support arm 61 of the partial ridging adjustment mechanism 6 also serves as a soil dividing hook mounting member.

[0039] Please refer to Figures 1 - 4 , the pressing mechanism 4 includes a pressing mounting arm 41, a pressing swing arm 42, an elastic top support member 43 and a pressing wheel 44. The pressing mounting arm 41 is connected to the crossbeam clamping plate of the frame 1 through fasteners. The pressing mounting arm 41 is located at the rear end of the frame 1.

Under the action of the elastic top support member 43, the pressing swing arm 42 has a tendency to rotate downward so that the pressing wheel 44 can press on the top of the ridge. When the height of the frame 1 changes due to terrain changes or sundries such as bumps, the elastic top support member 43 adaptively expands and contracts so that the pressing wheel 44 can always press on the ridge. When the ridge has a height change due to sundries, the pressing wheel 44 can adaptively lift to cross the obstacle.

[0040] In some embodiments, the elastic top support member 43 is a spring. The spring is provided on the pressing mounting arm 41 and the bottom end of the spring is connected to the pressing swing arm 42.

[0042] Limit nuts are screwed on both the lower side of the lower connecting member and the upper side of the upper connecting member of the support screw. The spring is sleeved on the support screw, and the two end portions of the spring are respectively abutted against the upper connecting member and the lower connecting member. The spring is installed through the support screw, the upper connecting member, and the lower connecting member to prevent the spring from deforming and affecting the elastic support effect on the rolling press wheel 44. Moreover, by rotating the limit nut above the upper connecting member, the support screw can be lifted or lowered to realize the height adjustment of the rolling press swing arm 42 and the rolling press wheel 44.

[0043] As a further embodiment, the limit nut above the upper connecting member is replaced by an adjusting handwheel, or the adjusting handwheel is connected to the limit nut above the upper connecting member. By rotating the adjusting handwheel, the support screw can be lifted or lowered. When the support screw is lifted, it drives the rolling press swing arm 42 to lift, so that the lowest rolling press height of the rolling press wheel 44 is lifted. When the support screw is lowered, it drives the rolling press swing arm 42 to lower, so that the lowest rolling press height of the rolling press wheel 44 is lowered.
