DETAILED DESCRIPTION

[0042] Reference Figure 1-7 The present invention provides a technical solution: a mixing device for each component of mud-bound pebbles, comprising a mixing box 1, in which a diversion mechanism 3, a liquid adding mechanism 4, a wrapping mechanism 2 and a mixing chamber are arranged in sequence from top to bottom. A driving motor 11 is installed on the top of the mixing box 1, and a stirring shaft 12 extending from top to bottom into the mixing chamber is rotatably installed at the lower output end of the driving motor 11, and a stirring blade 13 for stirring is installed on the lower end of the stirring shaft 12. A feeding port 14 is provided on the top of the mixing box 1, and the pebbles are input into the feeding port 14 through a conveyor belt 15 to flow to the diversion mechanism 3 for diversion and falling, and the falling pebbles are moistened by the liquid adding mechanism 4, the moistened pebbles are wrapped by the wrapping mechanism 2, and the wrapped pebbles are stirred by the stirring blade 13.

[0043] In this embodiment, the diversion mechanism 3 includes: a rotating ring box 31, which is fixedly sleeved on the stirring shaft 12, and a diversion plate 32 is installed at the bottom of the rotating ring box 31; a guide spacer 33, which is respectively arranged below the two side edges of the feed port 14, and its outer end is connected to the fixed mixing box 1 box wall, and its inner end is fixed with a fixed ring sleeve 34 sleeved on the outer side of the rotating ring box 31; a discharge port 35, which is arranged in an area close to one side of a group of the guide spacers 33 and below the diversion plate 32, and a conveyor belt 36 is correspondingly arranged below the outer end of the discharge port 35; specifically, the stirring shaft drives The diverter disc rotates, and the conveyor belt 1 guides the pebble material into the feed port, and the pebble material falls into the diverter disc between the two groups of guide spacers 33 for diversion and screening. Pebbles that meet the corresponding particle size range fall downward, and pebbles that do not meet the corresponding particle size range are guided into the discharge port and discharged into the conveyor belt 2 36; wherein, the partition surface of the guide spacer close to the side edge of the feed port is set to an inclined surface structure, and the initial end of the downward inclination leans against the upper disk surface of the diverter disc, so as to smoothly block the pebble material on the upper disk surface of the diverter disc, which is conducive to better promoting the diverter disc to divert the pebbles.

[0044] In this embodiment, the diverter plate 32 includes: an annular slide 325, which is arranged on the wall of the mixing box 1; a vibration rod 326, which is rotatably assembled on the side of the rotating ring box 31 through a damping bearing and is closely arranged in a circumference, and a diverter fan plate 321 is fixed to the outer end of the vibration rod 326, and the diverter fan plate 321 is provided with closely arranged diverter holes 322, and a screening sleeve 323 is installed in the diverter holes 322, and a telescopic slide column 324 is installed on the outer end of the diverter fan plate 321, and the telescopic slide column 324 is slidably and rotatably assembled on the annular slide 325, and the outer arc of the vibration rod 326 is fixed with a side tooth ring 327; the arc tooth ring 328 , arranged in the fixed ring sleeve 34 corresponding to the discharge port 35, and meshing with the side tooth ring 327; specifically, during the overall rotation of the diverter disc, the diverter fan plates that have not passed through the arc tooth ring area are arranged in a plane-oriented structure, and the diverter fan plates that have passed through the arc tooth ring area will be flipped under the transmission action of the side tooth ring and the arc tooth ring, thereby guiding the pebble material body that does not meet the corresponding particle size range into the discharge port, and under the continuous vibration of the vibration rod, it is beneficial to promote the pebble material body to enter the screening frame for screening, and to promote the pebbles to fall into the discharge port, avoiding the pebbles from being stuck in the screening frame and affecting the screening efficiency.

[0045] In this embodiment, the side gear ring 327 meshes with the arc gear ring 328 and rotates one circle.

[0046] In this embodiment, the screening frame 323 includes: an outer ring frame 3231, on the ring wall of which vertical strip slides 3232 are arranged at equal angles, the upper end of the strip slide 3232 is slidably connected with a slide seat 3233, and the lower end of the strip slide 3232 is fixed with a horizontal pneumatic spring rod 3234; a screening plate 3235, at both ends of which are respectively hingedly connected to the slide seat 3233 and the pneumatic spring rod 3234; a PCL controller is used to adjust the working extension and contraction amount of the pneumatic spring rod 3234; specifically, since the pebble material body generally contains pebbles of different size ranges, the overall introduction of the pebble material body and the mixing process of the binder will affect the collision balance with the stirring plate blades, making it difficult to quickly and evenly disperse and stir, resulting in incomplete and uneven mixing and dispersion. In this structure, according to the required The pebble material within the maximum particle size range is divided into multiple ranges from small to large: L1-L2, L2-L3, L3-L4..., and the PCL controller sequentially adjusts the working extension and contraction amounts L2, L3, L4... of the pneumatic spring rod. That is to say, when the pebble material is introduced as a whole, the pebble material within the range of L1-L2 is first sequentially introduced into the liquid adding mechanism 4, the material wrapping mechanism 2 and the mixing chamber for stirring, and then the pebble material within the range of L2-L3 is sequentially introduced into the liquid adding mechanism 4, the material wrapping mechanism 2 and the mixing chamber for stirring, and so on..., so that the particle size of the pebble material during each mixing and stirring is relatively uniform, and the collision with the stirring blades is improved to be more balanced, which is beneficial to the combination and dispersion of the pebble material and the binder.
