DETAILED DESCRIPTION

[0036] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a hanging platform under a weightlessness scale comprises a frame 1, the inner wall of the frame 1 is slidably connected to a slide plate 2, and the outer wall of the slide plate 2 is slidably connected to a weightlessness scale 3. Figure 1 It can be seen that a hopper is arranged on the top of the weight loss scale 3, a cylinder 4 is fixedly installed on the top of the frame 1, and the piston end of the cylinder 4 is fixedly installed on the top of the slide 2. Starting the cylinder 4 can drive the slide 2 to slide up and down on the inner wall of the frame 1, so that the slide 2 can drive the weight loss scale 3 to move up and down, a driving motor 5 is fixedly installed on the side wall of the slide 2, and a threaded rod 6 is fixedly installed on the output end of the driving motor 5. The outer wall of the threaded rod 6 is threadedly connected to the inner wall of the weight loss scale 3. The threaded rod 6 is driven by the driving motor 5 to rotate forward and reversely, and the weight loss scale 3 threadedly connected thereto can be driven to slide back and forth laterally on the outer wall of the slide 2 through the forward and reverse rotation of the threaded rod 6. A vacuum cleaner 7 is fixedly installed on the top of the frame 1, and an air suction pipe 8 is fixedly installed on the air suction end of the vacuum cleaner 7. A cleaning mechanism 9 for convenient cleaning of the weight loss scale 3 is arranged on the frame 1. By setting the cleaning mechanism 9, the dust attached to the inner wall of the hopper of the weight loss scale 3 can be cleaned.

[0037] The cleaning mechanism 9 comprises a baffle 91, a servo motor 92, a connecting rod 93, a connecting pipe 94, a worm gear 95, a worm 96, a dust suction pipe 97, a brush 99 and a through hole 98; the baffle 91 is fixedly mounted on the top of the frame 1, the inner wall of the baffle 91 is rotatably connected with a connecting pipe 94, and the connecting pipe 94 passes through the baffle 91, the top of the connecting pipe 94 is rotated on the inner wall of the suction pipe 8, and two groups of dust suction pipes 97 are fixedly mounted on the bottom of the connecting pipe 94, and a plurality of through holes 98 are provided on the dust suction pipe 97. At the same time, the dust swept by the brush 99 can be adsorbed by the vacuum cleaner 7 in cooperation with the suction pipe 8, the connecting pipe 94, the dust suction pipe 97 and the through hole 98. The outer wall of the connecting pipe 94 is fixedly mounted A worm gear 95 is installed, and a servo motor 92 is fixedly installed on the top of the baffle 91. A worm 96 is fixedly installed on the output end of the servo motor 92. The worm 96 is meshed with the worm gear 95. The servo motor 92 drives the worm 96 to rotate. While the worm 96 rotates, the worm gear 95 meshed with it can drive the connecting pipe 94 to rotate. One end of the connecting rod 93 is fixedly installed on the outer wall of the dust suction pipe 97, and the other end of the connecting rod 93 is fixedly installed with a brush 99. The two groups of dust suction pipes 97 are driven to rotate synchronously through the connecting pipe 94. At the same time, the connecting rod 93 can drive the brush 99 to make a circular motion around the connecting pipe 94. At this time, the powder adhered to the inner wall of the hopper can be swept down by the brush 99.

[0038] The connecting rod 93 is provided with an auxiliary mechanism 10, by which the brush 99 can be self-cleaned to avoid a large amount of dust adhering to the brush 99, which affects the cleaning effect of the brush 99 on the hopper of the weight loss scale 3. The auxiliary mechanism 10 includes a rotating rod 101, a small gear 102, a reed 103, a steel ball 104, and a large gear 105; one end of the rotating rod 101 is rotatably connected to the top of the connecting rod 93, and the other end of the rotating rod 101 is fixedly installed with a small gear 102, and the outer wall of the rotating rod 101 is fixedly installed with multiple groups of reeds 103, and the end of the reed 103 away from the rotating rod 101 is fixedly installed with a steel ball 1 04. The self-rotation of the rotating rod 101 in cooperation with the spring 103 can drive the steel ball 104 to repeatedly hit the brush 99, causing the brush 99 to vibrate slightly, so that the dust attached to the brush 99 can be knocked off, so that the brush 99 can be self-cleaned. A large gear 105 is fixedly installed on the bottom of the baffle 91, and the large gear 105 is meshed with the small gear 102. The dust suction tube 97 drives the connecting rod 93 to rotate and drives the rotating rod 101 to make a circular motion around the connecting tube 94. At the same time, in cooperation with the small gear 102 and the large gear 105, the rotating rod 101 can rotate while making a circular motion around the connecting tube 94.

[0039] Working principle: when it is necessary to clean the inner wall of the hopper of the weight loss scale 3, first start the driving motor 5 to drive the threaded rod 6 to rotate. The rotation of the threaded rod 6 can drive the weight loss scale 3 threadedly connected thereto to slide horizontally on the outer wall of the slide plate 2 and move to just below the baffle 91, so that the hopper of the weight loss scale 3 and the baffle 91 are in a concentric state. Then start the cylinder 4 to drive the slide plate 2 to slide upward on the inner wall of the frame 1, so that the slide plate 2 drives the weight loss scale 3 to move upward synchronously, so that the top of the hopper on the top of the weight loss scale 3 fits with the bottom of the baffle 91, and the hopper on the top of the weight loss scale 3 is sleeved on the outer wall of the two sets of brushes 99. At this time, start the servo motor 92 and the vacuum cleaner 7, and drive the spool 92 to move upward. The rod 96 rotates, and the worm 96 rotates, while the worm gear 95 meshing with it can drive the connecting pipe 94 to rotate, so that the connecting pipe 94 drives the two sets of dust suction pipes 97 to rotate synchronously. At the same time, the connecting rod 93 can drive the brush 99 to make a circular motion around the connecting pipe 94. At this time, the brush 99 will rotate in contact with the inner wall of the hopper on the top of the loss-in-weight scale 3. The powder adhered to the inner wall of the hopper can be swept down by the brush 99. At the same time, the dust swept down by the brush 99 can be adsorbed by the vacuum cleaner 7 in cooperation with the suction pipe 8, the connecting pipe 94, the dust suction pipe 97, and the through hole 98, thereby achieving a cleaning effect. Not only can the hopper on the top of the loss-in-weight scale 3 be fully cleaned, but the cleaning is also more convenient.

[0040] The dust suction tube 97 drives the connecting rod 93 to rotate and drives the rotating rod 101 to make a circular motion around the connecting tube 94. At the same time, in cooperation with the small gear 102 and the large gear 105, the rotating rod 101 can rotate while making a circular motion around the connecting tube 94. The self-rotation of the rotating rod 101 and the reed 103 can drive the steel ball 104 to repeatedly hit the brush 99, causing the brush 99 to vibrate slightly, so that the dust attached to the brush 99 can be knocked off, so that the brush 99 can be self-cleaned, avoiding a large amount of dust attached to the brush 99, which affects the cleaning effect of the brush 99 on the hopper of the weight loss scale 3.

[0041] 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 deviate from the spirit of the present invention are within the scope of protection of the present invention.
