Description

Technical Field

[0001] The utility model relates to the field of suction machine structures, in particular to a suction machine barrel structure which is easy to weld. Background Art

[0002] In a suction machine, its storage barrel includes a barrel body and a conical hopper installed in the barrel body. The traditional barrel body is divided into two sections, upper and lower. During welding, the annular protrusion at the upper end of the conical hopper is welded between the barrel bodies at both ends. The traditional manufacturing process can only weld the barrel body and the conical hopper at the outer periphery. The welding marks are exposed, affecting the overall aesthetics. Moreover, welding bosses are also required at the welding positions of the two sections of the barrel body, which makes the overall height of the barrel body higher and occupies a larger space. The two-section barrel body also leads to cumbersome welding procedures and low welding efficiency. Therefore, it is necessary to produce a barrel body structure of a suction machine that is easy to weld to solve the above problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figures 1 to 4 As shown, a barrel structure of a suction machine that is easy to weld includes a barrel body component 1 and a hopper component 2. The barrel body component 1 and the hopper component 2 are both made of metal. The barrel body component 1 includes an upper barrel wall 11, a lower barrel wall 12 and a first buckle ring 13 that are integrally arranged. The upper barrel wall 11, the lower barrel wall 12 and the first buckle ring 13 are all annular. The upper and lower ends of the first buckle ring 13 are respectively fixed to the lower end of the upper barrel wall 11 and the upper end of the lower barrel wall 12. The first buckle ring 13 is provided with a first arc-shaped boss 131 protruding into the barrel body. The hopper component 2 includes It includes a welding wall 21, a second buckling ring 22, a connecting wall 23 and a hopper body 24. The welding wall 21, the second buckling ring 22 and the connecting wall 23 are all annular. The upper and lower ends of the second buckling ring 22 are respectively fixed to the lower end of the welding wall 21 and the upper end of the connecting wall 23. The second buckling ring 22 is provided with a second arc-shaped boss 221 protruding into the barrel. The outer wall of the second arc-shaped boss 221 is buckled with the inner wall of the first arc-shaped boss 131. There is a gap between the welding wall 21 and the upper barrel wall 11. The hopper body 24 is fixed to the lower end of the connecting wall 23.

[0020] When assembling the hopper assembly 2 and the barrel body assembly 1, the hopper assembly 2 is placed into the barrel body assembly 1 from above. When the lower end of the second buckle ring 22 contacts the upper end of the first buckle ring 13, the hopper assembly 2 continues to be pressed down. Under the elastic action of the metal material, the second buckle ring 22 continues to move downward, so that the first arc-shaped boss 131 and the second arc-shaped boss 221 are buckled. Then the welding wall 21 and the upper barrel wall 11 can be welded. The solder enters the gap between the welding wall 21 and the upper barrel wall 11, so that the welding wall 21 and the upper barrel wall 11 are firmly welded and the welding mark is more beautiful. The advantages of this design are: the barrel body assembly 1 is integrally formed, and its manufacturing process is simple and the cost is low; the welding position is inside the barrel body assembly 1, and no external welding is required, which improves the beauty of the barrel body assembly 1 and reduces the height of the barrel body assembly 1; the assembly and welding steps of the barrel body assembly 1 and the hopper assembly 2 are simple, and the production efficiency is improved.

The fixing ring 61 is provided with a lower mounting ring 611 protruding inward, and the lower end of the lower barrel wall 12 is provided with an upper mounting ring 121 protruding outward. The lower end of the upper mounting ring 121 is in contact with the upper end of the lower mounting ring 611. The outer end of the pressure block 62 corresponds to the upper part of the fixing ring 61. The locking screw 63 passes through the outer end of the pressure block 62 and is threadedly connected to the fixing ring 61. The lower end of the inner end of the pressure block 62 is in contact with the upper end surface of the upper mounting ring 121.

[0024] When fixing the barrel body assembly 1 on the mounting base 6, first remove the pressing block 62 and the locking screw 63, place the upper mounting ring 121 on the lower barrel wall 12 on the lower mounting ring 611 of the fixing ring 61, and then lock the pressing block 62 by the locking screw 63 so that the inner end of the pressing block 62 presses the upper mounting ring 121 downward, thereby fixing the barrel body assembly 1.

[0025] In this design, an observation window assembly 7 is also included. The observation window assembly 7 includes an outer frame 71, a transparent plate 72 and a knob 73. An observation hole is opened in the lower barrel wall 12. The transparent plate 72 is fixed to the middle of the outer frame 71. The left and right sides of the outer frame 71 are fixed to the lower barrel wall 12 through the knob 73. The knob 73 is threadedly connected to the lower barrel wall 12, and the transparent plate 72 corresponds to the observation hole.

[0026] Through the transparent plate 72, the conditions inside the barrel body assembly 1 can be observed in real time. The outer frame 71 is fixed to the outside of the lower barrel wall 12 by rotation and can be flexibly disassembled and installed.
