[0037] like Figures 1 to 5 As shown, in one embodiment of the present application

[0038] A header fixing tool includes two symmetrically arranged fixing devices. The main purpose of the fixing devices is to fix the header module in the length and width directions. Since both sides need to be fixed, the two fixing devices are respectively arranged on both sides of the header module to adjust and fix the length and width directions.

[0039] Specifically, the fixing device of the utility model comprises: a header main bracket 1, an adjusting connecting rod 2, a locking adjustment device 3 and a fixed support end 4.

[0040] The main support 1 of the collection box is used to support and fix the end of the collection box. The main support 1 of the collection box includes a fixed connecting seat 11.

By arranging clamps 132 of different models and sizes on the upper clamp plate 1311, during the installation process of changing the model, it is only necessary to replace the upper clamp plate 1311 and two screws, find the clamp 132 of the corresponding size of the new collection box, and then reinstall the upper clamp plate 1311 and the lower clamp plate 1312, so as to match the end of the new collection box.

[0043] The clamp 132 includes two symmetrical arc-shaped buckles 1321 . A rubber strip is disposed inside each arc-shaped buckle 1321 , which can be used to limit the rotation caused by welding stress during the welding process of the header module.

[0044] Two clamp seats 133 are further provided between the clamp 132 and the clamp bracket 131. The upper surface of each clamp seat 133 is an inclined surface. The clamp 132 and each clamp seat 133 are welded and connected. The two clamp seats 133 are symmetrically arranged to form a V-shaped connecting surface, which can increase the welding area and make the connection between the clamp 132 and the clamp bracket 131 more firmly.

[0045] The utility model relates to an adjusting connecting rod 2, which is mainly used to support collection boxes of different lengths. One end of the adjusting connecting rod 2 is fixed on a collection box main bracket 1, and the other end of the adjusting connecting rod 2 is adjustably fixed on a fixed support end 4.

[0050] The lifting and adjusting device 14 of the utility model is used to adjust the height of the clamp part. Through the cooperation of the lifting and adjusting device 14 and the clamp device 13, it can be suitable for different types of header modules. The bottom end of the lifting and adjusting device 14 is fixed on the support frame 12, and the top end of the lifting and adjusting device 14 is fixed on the bottom of the clamp device 13. The lifting and adjusting device 14 controls the distance between the clamp device 13 and the support frame 12.

[0051] like Figure 3 As shown, in one embodiment of the utility model, the lifting adjustment device 14 includes an adjusting bolt 141 and a fixing nut 142, the adjusting bolt 141 and the fixing nut 142 are threadedly matched, the fixing nut is fixed on the support plate 122, the bottom end of the stud of the adjusting bolt 141 is connected to the bottom of the clamp device 13, and the distance between the clamp device 13 and the support plate 122 is changed by rotating the adjusting bolt 141. The fixing nut 142 is welded and fixed to the upper part of the support plate 122, and the adjusting bolt 141 penetrates and is threadedly matched with the fixing nut 142, so that only the head of the adjusting bolt 141 needs to be rotated, and the stud length of the adjusting bolt 141 on the upper surface of the support plate 122 will change, thereby changing the distance between the clamp device 13 and the support frame 12, and playing the role of adjustment.

[0052] like Figure 3 As shown, a protective tube 143 is provided outside the adjusting bolt 141 , and the upper end of the protective tube 143 is fixed to the bottom surface of the supporting plate 122 .

[0054] In summary: the clamp device is fastened to the upper part of the header main bracket by welding. When the diameter of the header module changes, only the overall clamp part needs to be replaced. When the length and width of the header module change, only the position of the mobile header main bracket needs to be changed, and the length of the adjusting connecting rod needs to be adjusted. Then, the locking adjustment device can be placed in the appropriate position and fixed by tightening the bolts and locking bolts to complete the production matching of the new model module header. The entire equipment is a universal tooling, which can match multiple models of module headers through adjustment. It has a wide range of overall use, and all operations are the rotation of threaded bolts. The overall method is simple and efficient, and the overall method is simpler and more beautiful than the traditional fixing method.
