The column is fixedly connected to the top of the base, and the two ends of the reinforcing connecting beam are fixedly connected to the column and the body connecting plate, respectively.

[0008] Preferably, the cross-section of the reinforcing connecting beam is H-shaped, and the height of the reinforcing connecting beam is adapted to the height of the vehicle body connecting plate.

[0009] In a further preferred embodiment, the connecting screw is configured as a "U" shape, and the top of the connecting screw forms two threaded sections that mate with the nut.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a micro-rotating soil leveler with stable connection and support, which has the following beneficial effects:

[0014] In this invention, several "U"-shaped connecting screws pass through the top of the frame and the base, and each connecting screw has two nuts threadedly connected to its top. This double-nut fixing method can effectively prevent the connecting screws from loosening and ensure a firm connection between the frame and the base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 A micro-rotary tiller with stable support includes a frame 10, rotary tillers 20, a gearbox 30, two sets of body connecting parts 40, and a protective part 50. The gearbox 30 is mounted on the top of the frame 10 and is connected to the rotary tillers 20 via a transmission. After being connected to a drive shaft in the body, the gearbox 30 transmits power, allowing the rotary tillers 20 to rotate within the frame 10. The two sets of body connecting parts 40 are located on opposite sides of the gearbox 30, and both sets are used for detachable connection and fixation to the frame 10 using fasteners such as bolts. The protective part 50 is mounted on the front side of the frame 10, and is positioned in front of the rotary tillers 20 with a gap between it and the blades. This prevents the protective part 50 from interfering with the normal use of the rotary tillers 20, and also provides some protection to the rotary tillers 20.

[0022] In this embodiment, the vehicle body connecting part 40 includes a base 41, a plurality of connecting screws 42 and nuts 43, a column 44, a reinforcing connecting beam 45, and a vehicle body connecting plate 46. The connecting screws 42 are U-shaped, and the top of the connecting screws 42 forms two threaded sections that mate with the nuts 43. Thus, when connecting and fixing the base 41 and the frame 10, the connecting screws 42 can pass through the top of the frame 10 and the base 41. Two nuts 43 are fitted onto the top of each connecting screw 42 and threadedly connected to it. After tightening the nuts 43, the connection between the base 41 and the frame 10 is completed. The column 44 is fixedly connected to the top of the base 41. The cross-section of the reinforcing connecting beam 45 is H-shaped, and the height of the reinforcing connecting beam 45 is adapted to the height of the vehicle body connecting plate 46. The two ends of the reinforcing connecting beam 45 are fixedly connected to the column 44 and the vehicle body connecting plate 46, respectively. The "H"-shaped reinforced connecting beam has high bending and torsional strength, which can effectively disperse and bear various forces generated by the leveler during operation, thereby enhancing the connection stability between the vehicle body and the vehicle body.

[0023] In this embodiment, the protective part 50 includes at least one set of lifting structures and a protective plate 53. The tops of the lifting structures are fixedly connected to the frame 10, and the bottoms of the lifting structures are fixedly connected to the protective plate 53. The lifting structures together support the protective plate 53. The lifting structure includes a lifting frame 51, a deflection sleeve 52, a connecting seat 54, a lifting rod 55, and a spring 56. The lifting frame 51 is fixedly connected to the frame 10, and the deflection sleeve 52 is disposed in the middle of the lifting frame 51 and rotatably connected to it. The lifting rod 55 passes through the deflection sleeve 52, and a limiting pin is inserted at the top of the lifting rod 55 to prevent the lifting rod 55 from falling out of the deflection sleeve 52. The bottom end of the lifting rod 55 is rotatably connected to the connecting seat 54, and the connecting seat 54 is fixedly connected to the protective plate 53. The spring 56 is sleeved on the outside of the lifting rod 55, and both ends of the spring 56 are in contact with the deflection sleeve 52 and the connecting seat 54, respectively. When the protective plate 53 is impacted, the connecting seat 54 can drive the hanging rod 55 to move within the deflection sleeve 52, causing the deflection sleeve 52 to change angle. This allows the protective plate 53 to swing, buffering and dispersing the impact force and preventing damage to the protective plate due to rigid collision. During the deflection movement of the protective plate 53, the spring 56 can be compressed. After the protective plate 53 is no longer subjected to external force, the deformation of the spring 56 allows the protective plate 53 to return to its initial position.
