DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] In this embodiment, as Figures 1-7 shown, a foldable auxiliary bridge plate structure for agricultural machinery going into the field includes a first main board 101 and a second main board 102. The first main board 101 and the second main board 102 are movably connected by a folding member, so that the first main board 101 and the second main board 102 can be folded and stacked together, thereby reducing the occupied area and facilitating storage and carrying. Symmetric sliding grooves 103 are provided inside the first main board 101, and auxiliary boards 104 are slidably arranged inside the sliding grooves 103 respectively, which is convenient for extending the length of the bridge plate structure to adapt to different slopes and has a good practical effect;

[0032] It also includes an adjusting mechanism 200 and a strengthening mechanism 300. The adjusting mechanism 200 is arranged inside the first main board 101 and is used to adjust the length of the auxiliary board 104 extending outside the first main board 101. The strengthening mechanism 300 is arranged on one side of the first main board 101 and the auxiliary board 104 and is used to increase the structural stability. Before the foldable auxiliary bridge plate structure for agricultural machinery going into the field starts to be used, first check whether the structure can be used normally, so as to adaptively adjust the adjusting mechanism 200 according to the on-site situation and make the structure enter the state of waiting to be used;

[0033] The folding member includes mounting seats symmetrically installed on one side of the first main board 101. A first connecting plate 105 is rotatably arranged between the mounting seats. The other side of the first connecting plate 105 is rotatably connected with a second connecting plate 106. Both ends of the second connecting plate 106 are rotatably connected with the second main board 102 through fixing seats, so that the first main board 101 and the second main board 102 can be smoothly folded and stacked together.

[0034] Among them, as Figure 4 and Figure 5 shown, the adjusting mechanism 200 includes a gear groove 201 arranged inside the first main board 101. A first bevel gear 202 is arranged inside the gear groove 201. A second bevel gear 203 is meshed on one side of the first bevel gear 202. One end of the gear shaft of the second bevel gear 203 extends outside the first main board 101 and is fixedly connected with a turning handle 204. The gear shaft of the first bevel gear 202 is fixedly connected with a bidirectional lead screw 205. Both ends of the bidirectional lead screw 205 are threadedly connected with the auxiliary board 104. When the user rotates the turning handle 204, the rotation operation of the second bevel gear 203 can be realized, and then the first bevel gear 202 and the bidirectional lead screw 205 are driven to rotate. The two side auxiliary boards 104 approach or move away from each other along the direction of the sliding groove 103, so as to realize the storage or extension effect of the auxiliary board 104.

[0035] Among them, as Figures 4-7As shown in the figure, the reinforcement mechanism 300 includes a support plate 301 fixedly arranged with the auxiliary plate 104. The support plate 301 is arranged on the side of the auxiliary plate 104 away from the first main board 101. A card slot 302 is arranged on the side of the support plate 301 away from the folding member. A plug post 303 is slidably arranged inside the card slot 302. The plug post 303 is clamped with the card slot 302 through a telescopic component, which is convenient for disassembly and installation. Thus, when the field entry position is relatively narrow, components such as the telescopic component and the plug post 303 can be smoothly disassembled. A telescopic rod 304 is fixedly arranged on one side of the plug post 303. The telescopic end of the telescopic rod 304 is connected to a limit plate 305. Limit blocks 306 are symmetrically arranged on the surface of the first main board 101 to play a positioning role. The limit plate 305 is sleeved outside the limit blocks 306, and the limit plate 305 is fixedly connected to the limit blocks 306 through a plurality of bolts, which increases the structural stability and ensures the smooth use of this structure.

[0036] As shown in Figure 7 the figure, the telescopic component includes a moving groove arranged inside the plug post 303. Through openings communicating with the moving groove are symmetrically arranged on both sides of the moving groove. A positioning block 307 is slidably arranged inside the through openings. Protrusions are arranged at both ends of the positioning block 307. A push plate 308 is slidably arranged inside the moving groove. The push plate 308 is fixedly connected to the inner wall of the moving groove through a spring. The other end of the push plate 308 is rotatably provided with a screw rod 309. The screw rod 309 is threadedly connected to the plug post 303. The user only needs to rotate the screw rod 309 to realize the movement operation of the push plate 308. When the push plate 308 contacts the positioning block 307, the push plate 308 squeezes the positioning block 307 to both sides, so that the positioning block 307 can be smoothly clamped into the positioning groove 310, thereby fixing and limiting the plug post 303 and the support plate 301.

[0037] As shown in Figure 1 and Figure 2 the figure, the second main board 102 is consistent with the first main board 101 in terms of specifications, dimensions, and structure. An adjustment mechanism 200 is also arranged inside the second main board 102, and a reinforcement mechanism 300 is also arranged on one side of the second main board 102.

[0038] As shown in Figure 3 the figure, a plurality of screw holes are arranged on the surface of the support plate 301, and screws are arranged inside the screw holes. It is convenient to insert the screws into the ground to fix the position of this structure, which is convenient for the operation of agricultural machinery entering the field.

[0039] As shown in Figures 5-7 the figure, the card slot 302 is adapted to the plug post 303 in terms of specifications and dimensions. Positioning grooves 310 communicating with the card slot 302 are arranged on both sides of the card slot 302. The positioning grooves 310 are adapted to the positioning blocks 307 in terms of specifications and dimensions, avoiding the situation of component jamming.

[0040] Embodiment 2

[0041] Differing from Embodiment 1, as Figure 8 shown, it further includes protective pads arranged on the surfaces of the first main board 101 and the second main board 102, increasing the contact area between this structure and the agricultural machinery and enhancing the friction effect. Elastic ropes 107 are fixedly installed on the sides of the first main board 101 and the second main board 102 away from the folding member, facilitating fixing them through the elastic ropes 107 after the first main board and the second main board are folded.

[0042] During use, first determine the required bridge board area according to the on-site situation and the size of the agricultural machinery. Rotate the handle 204 to rotate the second bevel gear 203, thereby driving the rotation of the first bevel gear 202 and the bidirectional lead screw 205. The two side auxiliary boards 104 move away from each other along the direction of the sliding groove 103, thus achieving the extension effect of the auxiliary boards 104. When adjusted to the appropriate length, insert the plug post 303 into the internal card slot 302, and the limiting plate 305 is sleeved outside the limiting block 306. Then rotate the screw 309, bolts, and screws to fix this structure, facilitating the subsequent operation of the agricultural machinery entering the field.

[0043] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
