Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] To solve the problems of low stability, complex structure, and inconvenient assembly existing in the prior art, the following technical solutions are given. Please refer to Figures 1-5 ;

[0028] An assembly structure of a metal support component for a small agricultural machine with high stability, comprising a chassis frame 1. A number of support bars 2 are welded inside the chassis frame 1. Above the support bars 2 is provided a rectangular frame 4. The number of the rectangular frames 4 is not less than three, and the rectangular frames 4 are arranged in a rippling pattern. Each rectangular frame 4 is formed by splicing four L-shaped angle steels 5 end to end. Each L-shaped angle steel 5 can be displaced vertically independently. The L-shaped angle steel 5 is connected to the support bar 2 through a telescopic member 3. Below the chassis frame 1 is provided a moving component 8. Above the chassis frame 1 is provided a partition 6. A space for placing the small agricultural machine is formed between the partition 6 and the L-shaped angle steel 5.

[0029] The L-shaped angle steel 5 includes a placement plate surface 51 and a limit plate surface 52. The placement plate surface 51 is parallel to the horizontal plane, and the limit plate surface 52 is perpendicular to the horizontal plane. The small agricultural machine can be placed on the placement plate surface 51. Due to its own gravity, the small agricultural machine presses down the L-shaped angle steel 5 it contacts, and the small agricultural machine sinks accordingly. The adjacent L-shaped angle steels 5 that are not pressed down use their limit plate surfaces 52 to limit the base of the small agricultural machine in four directions. Setting multiple placement plate surfaces 51 and limit plate surfaces 52 can adapt to the bases of agricultural machines of different sizes and shapes, and the installation is convenient.

[0030] The support bars 2 are arranged in a radial pattern, and the intersections of the support bars 2 are connected by welding.

[0031] The telescopic member 3 includes a telescopic rod 31, a high-strength spring 32 and a connecting plate 33. The telescopic rod 31 is arranged inside the high-strength spring 32. Setting the telescopic rod 31 can limit the moving direction of the L-shaped angle steel 5, making it only move along the vertical direction, avoiding its skew when the small agricultural machine is placed and unable to play a good role in placement and limitation. Connecting plates 33 are provided at both ends of the telescopic rod 31 and the high-strength spring 32. The ends of the telescopic rod 31 and the high-strength spring 32 are welded to the connecting plate 33. Setting the connecting plate 33 can make the telescopic rod 31 and the high-strength spring 32 form a complete prefabricated part. During welding, only the connecting plate 33 needs to be welded to the corresponding position, which is convenient for assembly. The connecting plate 33 above the high-strength spring 32 is welded to the bottom surface of the placement plate surface 51, and the connecting plate 33 below the high-strength spring 32 is welded to the upper surface of the support bar 2.

[0032] The partition 6 includes a fixed partition 61 and a movable partition 62. The fixed partition 61 and the movable partition 62 are provided to protect small agricultural machinery, preventing the small agricultural machinery from falling off the L-shaped angle steel 5 when moving or shaking. There are two fixed partitions 61 which are oppositely arranged. The bottom of the fixed partition 61 is welded to the chassis frame 1. There is a movable partition 62 between the fixed partitions 61. There are two movable partitions 62 which are oppositely arranged. One side of the movable partition 62 is connected to the fixed partition 61 through a hinge 63, and the other side of the movable partition 62 is connected to the fixed partition 61 through a lock 64. When placing or removing the small agricultural machinery, the lock 64 can be opened to open the two movable partitions 62, facilitating the operator to carry the small agricultural machinery. There are bars 65 on the fixed partition 61 and the movable partition 62. There is an operation window 66 in the middle of the movable partition 62. The operation window 66 is welded to the bars 65 on its two sides. During daily use, the operator can perform corresponding operations on the small agricultural machinery through the operation window 66.

[0033] The moving component 8 includes rollers 81, roller shafts 82 and feet 83. The feet 83 are welded to the four corners of the chassis frame 1 and the bottom surface of the support bars 2. There are roller shafts 82 between the feet 83, and there are rollers 81 on the roller shafts 82. There is one roller 81 at each of the four corners of the chassis frame 1 and the bottom surface of the support bars 2, increasing the contact points of the rollers 81 with the ground, making the chassis frame 1 more stable when placed and preventing the chassis frame 1 from shaking due to rough ground. The length of the roller 81 is greater than the diameter of the roller 81, greatly increasing the contact surface of the roller 81 with the ground and improving the stability during movement and placement. The outer layer of the roller 81 is provided with an elastic layer, and the elastic layer can be made of rubber or thermoplastic elastic material. When the chassis frame 1 is placed, the elastic layer can, to a certain extent, prevent the chassis frame 1 from being unevenly placed due to ground protrusions, and can also absorb a certain amount of vibration when the chassis frame 1 is moving, making the movement smoother. There is a pusher 7 on the outer side of one of the fixed partitions 61 facing outwards. The bottom end of the pusher 7 is welded to the fixed partition 61. The operator can push the pusher 7 to move the entire device.

[0034] Working principle: The small agricultural machine is placed on the placing plate surface 51. Due to its own gravity, the small agricultural machine presses down the L-shaped angle steel 5 it contacts, and the small agricultural machine sinks accordingly. The adjacent L-shaped angle steels 5 that are not pressed down use their limiting plate surfaces 52 to limit the base of the small agricultural machine in four directions, making the placement of the small agricultural machine more stable. The fixed partition 61 and the movable partition 62 are provided to protect the small agricultural machine and prevent it from falling off the L-shaped angle steel 5 when moving or shaking. A roller 81 is provided at each of the four corners of the chassis frame 1 and the bottom surface of the support bar 2, increasing the contact points of the rollers 81 with the ground, making the placement of the chassis frame 1 more stable and preventing the chassis frame 1 from shaking due to rough ground. An elastic layer is provided on the outer layer of the roller 81. When the chassis frame 1 is placed, the elastic layer can, to a certain extent, prevent the chassis frame 1 from being unevenly placed due to ground protrusions and can also absorb a certain amount of vibration when the chassis frame 1 is moved, making the movement smoother.
