[0019] Example:

[0020] like Figures 1 to 5As shown, the utility model provides an aggregate weighing device for concrete processing, comprising a bottom plate 1, a symmetrically distributed support plate 11 is fixedly installed on the top of the bottom plate 1, a conveyor belt 12 is commonly provided on the opposite sides of the two support plates 11, a bracket 13 is fixedly installed on the top of the bottom plate 1, a feed pipe 14 is fixedly penetrated through the top of the bracket 13, a weighing bucket 15 is fixedly installed on the top of the feed pipe 14, a rotating rod 16 is rotatably penetrated through the top of the feed pipe 14, a sleeve 17 is fixedly sleeved on the outer side of the rotating rod 16, a uniformly distributed fixed plate 18 is fixedly installed on the outer side of the sleeve 17, a symmetrically distributed first unloading plate 19 is fixedly installed below the fixed plate 18, the first unloading plate 19 is fixedly connected to the inner wall of the feed pipe 14, a mounting plate 191 is provided below the first unloading plate 19, and the mounting plate 191 and the feed pipe 14 are fixedly connected. The inner wall of the tube 14 is fixedly connected, and a movable plate 192 is provided above the mounting plate 191. A symmetrically distributed blocking plate 8 is fixedly installed on the bottom end of the movable plate 192. By setting the blocking plate 8, bone mud is prevented from falling onto the mounting plate 191 from both sides; a plurality of evenly distributed support members 193 are fixedly installed on the top of the mounting plate 191, and a movable rod 194 is movably penetrated through the middle of the support member 193. The top of the movable rod 194 is fixedly connected to the movable plate 192, and the movable rod 194 and the support member 193 are fixedly connected by a first spring 195. Two diagonally distributed electric push rods 196 are fixedly installed on the bottom end of the movable plate 192, and a push block 197 is fixedly installed on the output end of the electric push rod 196. The push block 197 penetrates the movable plate 192, and a push plate 198 is fixedly installed on the top of the push block 197.

[0021] See Figures 4 and Figure 5 The scraper 2 is fixedly mounted on opposite sides of the two support plates 11 of the present application, and a collecting plate 21 is arranged below the scraper 2. The collecting plate 21 is arranged in an inclined state. By setting the scraper 2 and the collecting plate 21, the scraper 2 can scrape the bone mud remaining on the conveyor belt 12, and then drop it through the collecting plate 21, so that the weight of the bone mud can be more accurate.

[0022] See also Figure 5The two support plates 11 of the present application rotate together and are penetrated by a rotating shaft 3. The outer fixed sleeve of the rotating shaft 3 is provided with a protrusion 31. The protrusion 31 and the collecting plate 21 are used in conjunction with each other. A symmetrically distributed stabilizing rod 32 is fixedly installed on one side of the top of the bottom plate 1 close to the collecting plate 21. A connecting rod 33 is movably inserted inside the stabilizing rod 32. The connecting rod 33 and the collecting plate 21 are fixedly connected. The collecting plate 21 and the stabilizing rod 32 are fixedly connected by a second spring 34. By driving the rotating shaft 3 to rotate, the protrusion 31 is driven to rotate. When the protrusion of the protrusion 31 contacts the collecting plate 21, the protrusion 31 lifts the collecting plate 21 for a distance. At the same time, the collecting plate 21 drives the connecting rod 33 and the second spring 34 to rise. When the protrusion of the protrusion 31 is separated from the collecting plate 21, the collecting plate 21 moves downward, and the speed of the collecting plate 21 moving downward is increased under the action of the second spring 34. This is repeated so that the collecting plate 21 can vibrate, thereby preventing bone mud from remaining on the surface of the collecting plate 21.

[0023] See also Figure 1 A first motor 4 is coaxially fixedly installed at one end of the rotating shaft 3, and a second motor 41 is coaxially fixedly installed at one end of the rotating rod 16. By setting the first motor 4, the rotating shaft 3 can be rotated conveniently, and by setting the second motor 41, the rotating rod 16 can be rotated conveniently.

[0024] See also Figure 3 Two empty slots 5 are provided at the top of the movable plate 192, and the two empty slots 5 are diagonally distributed. The push block 197 passes through the empty slots 5. By providing the empty slots 5, the push block 197 can move smoothly.

[0025] See also Figure 2 and Figure 3 Two collecting boxes 6 are fixedly installed at the bottom end of the movable plate 192. The two collecting boxes 6 are respectively located below the two empty slots 5. The push block 197 is in contact with the lower surface of the inner wall of the collecting box 6. By setting the collecting box 6, bone mud is prevented from falling onto the mounting plate 191. When the electric push rod 196 pushes the push block 197 to move, the push block 197 can push the bone mud in the collecting box 6 down, thereby avoiding the situation where the residual bone mud causes the final weight to be incorrect.

[0026] See also Figure 3 A symmetrically distributed second unloading plate 7 is provided below the mounting plate 191 . The two second unloading plates 7 are fixedly connected to the inner wall of the feed pipe 14 . By providing the second unloading plates 7 , the bone mud can smoothly fall to the top of the conveyor belt 12 .

[0027] The working principle of the present application is as follows: when in use, the bone mud enters the feed pipe 14 through the weighing bucket 15, and the bone mud enters the middle of the multiple fixed plates 18 through the multiple fixed plates 18, and the sleeve 17 and the fixed plate 18 are driven to rotate by driving the rotating rod 16. At this time, the top fixed plate 18 rotates to the bottom, so that the bone mud falls into the top of the movable plate 192 through the first unloading plate 19. Since the bone mud has a certain weight, it drives the movable plate 192 to move downward, and the movable plate 192 drives the movable rod 194 to move in the support member 193. At the same time, the first spring 195 is deformed, and then the electric push rod 196 is driven so that the output end of the electric push rod 196 drives the push block 197 and the push plate 198 to move, pushing the bone mud on the top of the movable plate 192 down, and then falling onto the surface of the conveyor belt 12. The movable plate 192 is reset by the first spring 195 to facilitate the next use; by setting the scraper 2 and the collecting plate 21, the scraper 2 can scrape off the bone mud remaining on the conveyor belt 12, and then fall through the collecting plate 21, so that the weight of the bone mud can be more accurate.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
