[0045] The bottom plate 1 is detachably fixedly connected with a support frame 37, and the support frame 37 is provided with a positioning bar 38, one end of the positioning bar 38 is detachably fixedly connected with the support frame 37, and the other end of the positioning bar 38 is provided with a positioning groove 39;

[0046] In fact, the air intake pipe 4 includes a first pipe section 41, a second pipe section 42 and a third pipe section 43, which are connected in sequence. A branch pipe 44 is provided on the third pipe section 43. When the air intake pipe 4 is positioned before welding, the two positioning frames correspond to the first pipe section 41 and the second pipe section 42 respectively, and the support plate 34, the side plate 35 and the positioning strip 38 are used to position the third pipe section 43. The specific method is as follows:

[0047] First, the first pipe section 41 is positioned by fitting one end of the first pipe section 41 to the first limiting plate 21, placing the first pipe section 41 in the groove 32, and making the outer peripheral wall of the first pipe section 41 abut against the inclined surfaces of the two rotating plates 332 on one side facing backward, so that the first pipe section 41 is positioned;

[0048] Then, the second pipe section 42 is positioned, one end of the second pipe section 42 is aligned with the end of the first pipe section 41 away from the limiting plate, and the second pipe section 42 is placed in the groove 32, and the outer peripheral wall of the second pipe section 42 is abutted against the inclined surfaces of the two rotating plates 332 on the rear side, so that the first pipe section 41 is positioned;

[0049] Subsequently, the third pipe segment 43 is positioned, the third pipe segment 43 is abutted against the top of the support plate 34, and the outer peripheral wall of the third pipe segment 43 is abutted against one side of the side plate 35. At the same time, one end of the third pipe segment 43 is aligned with the end of the second pipe segment 42 away from the first pipe segment 41, and the other end of the third pipe segment 43 is aligned with the second limiting plate 22. In fact, the positioning groove 39 matches the branch pipe 44, the branch pipe 44 is placed in the groove 32, and the outer peripheral wall of the branch pipe 44 is aligned with the inner wall of the groove 32. In this way, the positioning of the third pipe segment 43 is achieved.

[0050] Of course, the first pipe segment 41, the second pipe segment 42 and the third pipe segment 43 are positioned in the same order;

[0051] When the diameter of the intake pipe 4 changes, the screws are loosened to move the side plate 35 on the guide rod 361, and the moving direction is toward or away from the support plate 34, and the moving distance is determined according to the diameter of the third pipe section 43. After the side plate 35 has moved, the screws are tightened to fix the side plate 35 and the guide rod 361, that is, to fix the side plate 35 and the bottom plate 1. At the same time, the knob 3312 is rotated to rotate the lead screw 3311, driving the two sliders 3313 on the same lead screw 3311 to move closer or farther. When the two sliders 3313 move closer, the two rotating plates 332 in the same groove 32 rotate closer around their corresponding pin shafts 333. When the two sliders 3313 When moving away, the two rotating plates 332 in the same groove 32 rotate away from each other around their respective corresponding pin shafts 333, and the angle between the two rotating plates 332 in the same groove 32 can be adjusted according to the diameters of the first pipe section 41 and the second pipe section 42. The height of the first pipe section 41 and the second pipe section 42 after positioning is determined by adjusting the angle between the two rotating plates 332, so that the first pipe section 41, the second pipe section 42 and the third pipe section 43 are at the same height. In this way, it can be suitable for the assembly and positioning of intake pipes 4 with different diameters. Compared with the prior art, there is no need to disassemble and replace the limit frame 31, so as to avoid frequent replacement of the limit frame 31 and affect the stability of the connection with the base plate 1, and the operation is convenient.

[0052] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
