Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

The terms used in the description of this utility model are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0028] As Figures 1 to 5 shown, the air inlet duct fixing seat of the new energy weeding machine includes: a body 01, and a plurality of assembly holes 02 and positioning columns 03 arranged on the inner side surface of the body 01. The diameter of one end of the body 01 is reduced to form an inward concave funnel shape. The assembly holes 02 and the positioning columns 03 are arranged in one-to-one correspondence and are respectively located at both ends of the inner side surface of the body 01;

[0029] Among them, a first radial reinforcing rib 1 is arranged between the assembly hole 02 and the positioning column 03. Both ends of the first radial reinforcing rib 1 are fixedly connected to the outer shaft surfaces of the assembly hole 02 and the positioning column 03 respectively. A first transverse reinforcing rib 2 is arranged between adjacent two assembly holes 02, and a second transverse reinforcing rib 3 is arranged between adjacent two first radial reinforcing ribs 1. The first radial reinforcing rib 1, the first transverse reinforcing rib 2 and the second transverse reinforcing rib 3 are arranged vertically and horizontally on the inner side surface of the body 01 to form a grid-like structure.

[0030] In this utility model, the first radial reinforcing rib 1, the first transverse reinforcing rib 2 and the second transverse reinforcing rib 3 arranged vertically and horizontally form a grid-like structure, significantly improving the overall strength and rigidity of the fixing seat and enhancing the durability of the fixing seat; at the same time, arranging the first radial reinforcing rib 1 between the assembly hole 02 and the positioning column 03 can effectively resist deformation, ensure the precise fit between the air inlet duct and the fixing seat, and improve the accuracy and stability of assembly; moreover, the arrangement of multiple reinforcing ribs increases the local wall thickness of the body 01, effectively preventing deformation during the die-casting production process and reducing the rejection rate.

[0031] On the basis of the above embodiment, at least two second radial reinforcing ribs 4 are arranged between the adjacent first transverse reinforcing rib 2 and the second transverse reinforcing rib 3. The second radial reinforcing ribs 4 divide the space enclosed by the first radial reinforcing rib 1, the first transverse reinforcing rib 2 and the second transverse reinforcing rib 3; by setting the second reinforcing ribs to act together with the first radial reinforcing rib 1, the first transverse reinforcing rib 2 and the second transverse reinforcing rib 3, a more dense grid-like structure is formed, improving the overall rigidity; when the fixing seat is subjected to external force, the second radial reinforcing ribs 4 can help disperse stress, reduce the dependence on a single reinforcing rib, and thus reduce the risk of damage caused by stress concentration.

[0032] Based on the above embodiments, two third transverse reinforcing ribs 5 are provided on the outer side surface of each positioning post 03, and the two third transverse reinforcing ribs 5 are respectively arranged in parallel with the second transverse reinforcing ribs 3 on both sides; by providing the third transverse reinforcing ribs 5 on both sides of the positioning post 03, additional support is provided for the positioning post 03 located at the edge position of the body 01. Acting together with the first radial reinforcing rib 1, a three-point support structure is formed, enhancing the structural stability of the positioning post 03, preventing the positioning post 03 from bending and deforming, and making it more durable.

[0033] Based on the above embodiments, a third radial reinforcing rib 6 is provided between the second transverse reinforcing rib 3 and the parallel third transverse reinforcing rib 5. The two ends of the third radial reinforcing rib 6 are respectively fixedly connected to the side surface of the second transverse reinforcing rib 3 and the end portion of the third transverse reinforcing rib 5 facing away from the positioning post 03; by providing the third radial reinforcing rib 6 to connect the third transverse reinforcing rib 5 and the second transverse reinforcing rib 3, an additional grid structure is further formed between the respective reinforcing ribs, so as to be able to evenly disperse the stress acting on the fixed seat and reduce the risk of product deformation.

[0034] Based on the above embodiments, the second radial reinforcing rib 4 and the third radial reinforcing rib 6 on both sides of the same second transverse reinforcing rib 3 are located on the same straight line of the same radius of the body 01; it is convenient for the material flow distribution to be uniform during die casting molding, which is convenient for molding, thereby improving the overall molding quality; and the second radial reinforcing rib 4 and the third radial reinforcing rib 6 are connected on the same straight line, so that the formed grid structure is evenly distributed, and the overall stress of the fixed seat can be evenly distributed on the fixed seat, reducing local stress concentration and improving the durability and reliability of the fixed seat.

[0035] Based on the above embodiments, the thickness of the first radial reinforcing rib 1 is greater than the thicknesses of the second radial reinforcing rib 4, the third radial reinforcing rib 6, the first transverse reinforcing rib 2, the second transverse reinforcing rib 3, and the third transverse reinforcing rib 5; the first radial reinforcing rib 1 is located between the assembly hole 02 and the positioning post 03 and is in the main stress-bearing area of the fixed seat. By increasing its thickness, additional strength can be provided to ensure durability in the high-stress area; prevent the assembly hole 02 and the positioning post 03 from bending and deforming, and ensure the alignment of the hole positions during assembly.

[0036] Based on the above embodiments, an installation opening 7 is provided between adjacent positioning posts 03. The installation opening 7 is set as a semi-circular structure with one side open and is located in the space formed by enclosing the second transverse reinforcing rib 3 and the third radial reinforcing ribs 6 on both sides; the semi-circular installation opening 7 makes the assembly of the air inlet duct more convenient, is easy to determine and align the relative position and angle between the fixed seat and the air inlet duct, and at the same time avoids interfering with the positions of the respective reinforcing ribs and is convenient for disassembly.

[0037] On the basis of the above embodiments, the axes of the assembly holes 02 and the positioning posts 03 are both arranged parallel to the axis of the body 01; ensuring the alignment of the assembly holes 02 and the positioning posts 03 with the fixed seat body 01, making the assembly process of the air inlet duct more direct and simple; after the assembly is completed, the overall structural stability of the fixed seat is improved, making the fixed seat more stable when bearing external forces.

[0038] On the basis of the above embodiments, four groups of assembly holes 02 and positioning posts 03 are provided; increasing the number of the assembly holes 02 and the positioning posts 03 can provide more fixing points, thereby enhancing the connection stability between the air inlet duct and the fixed seat, reducing the load on a single fixing point, and improving the durability of the structure.

[0039] On the basis of the above embodiments, the included angle between each group of assembly holes 02 and positioning posts 03 is set to 90°, so that the assembly holes 02 and the positioning posts 03 are evenly distributed on the fixed seat, forming a square layout, which helps to evenly disperse the load of the air inlet duct; at the same time, it also makes the positions of the respective reinforcing ribs between the assembly holes 02 and the positioning posts 03 evenly distributed, ensuring the force stability, thereby improving the overall rigidity of the fixed seat and reducing the deformation or damage caused by asymmetric loads.

[0040] Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
