DETAILED DESCRIPTION

[0034] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a vacuum tank, comprising a main body 1, a feed pipe 2 is slidably connected to the top of the main body 1, a sealing cover 3 is movably installed on the top of the feed pipe 2, the sealing cover 3 can seal the feed pipe 2 after unloading, an anti-blocking structure 4 is provided inside the main body 1, and a knocking structure 5 is provided inside the main body 1.

[0035] The anti-blocking structure 4 comprises: a support plate 41, a motor 42, a rotating rod 43, a protrusion 44, a return block 45, a connecting rod 46, an auxiliary block 47, and a guide groove 48. The inner top surface of the main body 1 is fixedly connected with the support plate 41, and the main body 1 plays a fixing role on the support plate 41. The outer wall of the support plate 41 is fixedly connected with the motor 42, and the support plate 41 plays a fixing role on the motor 42. The output end of the motor 42 is fixedly connected with the rotating rod 43, and the motor 42 can drive the rotating rod 43 to rotate. The outer wall of the rotating rod 43 penetrates the support plate 41 and is rotatably connected to the penetration point of the support plate 41. The outer wall of the support plate 41 is provided with a guide groove 48, and the inner wall of the guide groove 48 is slidably connected with the auxiliary block 47. The guide groove 48 plays a fixing role on the moving trajectory of the auxiliary block 47, thereby ensuring that the auxiliary block 47 can only move up and down. The end of the auxiliary block 47 away from the guide groove 48 is fixedly connected with the return block 45, and the moving trajectory of the return block 45 is fixed by the auxiliary block 47 , so that the return block 45 can only move in the up and down directions, and the end of the rotating rod 43 away from the motor 42 is fixedly connected with a protrusion 44, and the rotating rod 43 fixes the protrusion 44, and the protrusion 44 will perform a circular motion with the rotating rod 43 as the center as the rotating rod 43 rotates, the inner wall of the return block 45 fits the protrusion 44, and the protrusion 44 will push the inner wall of the return block 45, so that the return block 45 can reciprocate up and down, and the top of the return block 45 is fixedly connected with a connecting rod 46, and the return block 45 fixes the connecting rod 46, so that the connecting rod 46 will move with the movement of the return block 45, and the end of the connecting rod 46 away from the return block 45 is fixedly connected to the feeding pipe 2, and the feeding pipe 2 will move with the movement of the connecting rod 46, so that the feeding pipe 2 will shake.

[0036] The knocking structure 5 comprises: an auxiliary plate 51, a return spring 52, a metal plate 53, and a metal ring 54. The inner wall of the main body 1 is fixedly connected with the auxiliary plate 51, and the main body 1 plays a fixing role on the auxiliary plate 51. The top of the auxiliary plate 51 is fixedly connected with the return spring 52, and the auxiliary plate 51 plays a fixing role on the return spring 52. The end of the return spring 52 away from the auxiliary plate 51 is fixedly connected with the metal plate 53. The return spring 52 will push the metal plate 53 to move away from the return spring 52 through its own elastic force, thereby ensuring that the metal ring 54 can hit the metal plate 53 every time it moves downward. The bottom of the feed pipe 2 is fixedly connected with the metal ring 54, and the metal ring 54 will move with the movement of the feed pipe 2.

[0037] Working principle: The motor 42 drives the rotating rod 43 to rotate. At this time, the protrusion 44 will perform a circular motion with the rotating rod 43 as the center as the rotating rod 43 rotates. At this time, the protrusion 44 will push the inner wall of the return block 45. At the same time, because the auxiliary block 47 can only move along the direction of the inner wall of the guide groove 48, the return block 45 will move up and down due to the push of the protrusion 44. At this time, the connecting rod 46 will move up and down with the up and down reciprocating movement of the return block 45, and then the feeding pipe 2 will be driven to move up and down through the connecting rod 46, so that the feeding pipe 2 will shake, and then the low molecular impurities on the inner wall of the feeding pipe 2 will be shaken off, thereby avoiding the clogging of the feeding pipe 2.

[0038] At the same time, the metal ring 54 will continuously move up and down as the feed pipe 2 moves back and forth, so that the metal ring 54 and the metal plate 53 will continuously collide, and the feed pipe 2 will vibrate, thereby shaking off the low molecular impurities solidified on the inner wall of the feed port. At the same time, the reset spring 52 will push the metal plate 53 to reset by its own elastic force every time the metal ring 54 hits the metal plate 53 close to the auxiliary plate 51, thereby ensuring that the metal ring 54 can hit the metal plate 53 every time it moves downward.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
