[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 4 As shown, a bridge structure fixing seat for a wheat harvester comprises a support base 1 and a limit plate 2, wherein the support base 1 and the limit plate 2 are detachably connected; the support base 1 is fixedly connected to the wheat frame; the support base 1 is U-shaped, the limit plate 2 matches the upper part of the support base 1, and the lower part of the limit plate 2 is provided with an arc-shaped notch, and the arc-shaped notch and the lower part of the support base 1 form a fixed area for the driving shaft of the bridge structure, wherein the fixed area is in the shape of a circular ring, the upper opening of the support base 1 is wide at the top and narrow at the bottom, and the limit plate 2 is a structure of wide at the top and narrow at the bottom. The support base 1 is provided with two first pin holes 11 located on both sides of the U-shaped structure, and the limit plate 2 is provided with a second pin hole 21 at a position corresponding to the first pin hole 11, and the second pin hole 21 and the two first pin holes 11 are provided with a fixed pin shaft 3. The support base 1 and the limit plate 2 of this embodiment can be integrally injection molded. The structure of the limit plate 2 of this embodiment should be compatible with the structure of the support base 1, so that the limit plate 2 can always be inserted into the upper part of the support base 1, and the arc-shaped notch 21 and the lower part of the support base 1 form a fixed area.

[0027] In the assembly method of the bridge structure fixing seat of the wheat harvester in this embodiment, the limit plate 2 is inserted into the upper part of the support base 1, and the fixing pin shaft 3 passes through the second pin hole 21 and the two first pin holes 11, thereby fixing the support base 1 and the limit plate 2. At this time, the arc-shaped notch 21 and the lower part of the support base 1 form a fixed area, and the fixed area is for the driving shaft of the bridge structure to rotate.

[0028] When it is necessary to fix the driving shaft of the bridge structure to the wheat frame, it can be achieved through the bridge structure fixing seat of the wheat harvester. First, fix the support base 1 on the wheat frame, then put the driving shaft into the lower part of the support base 1, and then fix the limit plate 2 on the upper part of the support base 1. The fixed pin shaft 3 passes through the second pin hole 21 and the two first pin holes 11. At this time, the support base 1 and the limit plate 2 are fixed, the driving shaft is located in the fixed area, and the driving shaft can rotate in the fixed area. The above assembly work can be completed with the cooperation of fewer staff.

[0029] When the driving shaft and the wheat frame of the bridge structure need to be disassembled, it is also achieved through the bridge structure fixing seat of the wheat harvester. Only the limit plate 2 can be disassembled from the upper part of the support base 1, and then the driving shaft can be disassembled from the support base 1.

[0030] The wheat harvester bridge structure fixing seat of the present embodiment can firstly realize the rapid assembly of the driving shaft of the bridge structure and the wheat frame, thus saving manpower; secondly, when the driving shaft has a problem and needs to be repaired, the driving shaft can be quickly disassembled, thus facilitating the subsequent repair of the driving shaft.

[0031] As an implementation method, a connection base 4 for connecting to a wheat rack is fixedly arranged below the support base 1, and a fixing hole 41 is provided on the connection base 4. Specifically, a plurality of the fixing holes 41 are evenly located on both sides of the U-shaped structure, and the fixing holes 41 on the connection base 4 are fixedly connected to the wheat rack, so that the support base 1 is fixed on the wheat rack.

[0032] As an implementable embodiment, a first reinforcing plate 5 is provided between the support base 1 and the connecting seat 4. The provision of the first reinforcing plate 5 enhances the connection strength between the support base 1 and the connecting seat 4. The first reinforcing plate 5 has a more streamlined structure and occupies less space, and does not make the overall weight of the bridge structure fixing seat of the wheat harvester too large, thereby reducing the burden on the wheat frame after it is installed on the wheat frame.

[0033] As an implementation method, a second reinforcing plate 6 is provided between the support base 1 and the connecting base 4, and the second reinforcing plate 6 is located on the side of the first reinforcing plate 5. Figure 2 , the first pin hole 11 passes through the top of the second reinforcing plate 6. The provision of the second reinforcing plate 6 further enhances the connection strength between the supporting base 1 and the connecting seat 4.

[0034] As an implementable embodiment, a weight-reducing hole 51 is provided on the first reinforcing plate 5. The purpose of providing the weight-reducing hole 51 is to further reduce the weight of the fixing seat of the bridge structure of the wheat harvester, so that it will impose less burden on the wheat frame after being installed on the wheat frame. The specific way to fix the connecting seat 4 on the wheat frame is that the weight-reducing hole 51 in this embodiment is of small size, so the connecting seat 4 is generally manually locked with the wheat frame through the fixing hole 41, nuts and bolts. If the weight-reducing hole 51 is designed to be of large size, it can be fixed with a pneumatic gun, wherein the weight-reducing hole 51 can also play the role of making way for the sleeve of the pneumatic gun.

[0035] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included in the scope of the patent application of the present invention.
