Dynamic connection. It should be noted that the activated carbon ratio raw materials are put into the box body 1 from the top, and the stirring structure 2 is turned on to complete the raw material ratio stirring. After the stirring is completed, the material receiving cart is moved to the bottom of the box body 1. The operator holds one end of the special-shaped rod 301 with both hands and swings it, thereby driving the bottom cover 302 to rotate along the direction of the first hinge 306, so that the bottom of the box body 1 is opened, and the mixed raw materials slide directly from the inclined bottom cover 302. After the stirring is completed, the raw materials fall directly due to gravity and do not need to be dug out by manpower. The operation is simple and convenient. The special-shaped rod 301 is used to control the opening of the bottom cover 302, and the traditional direct bottom position operation of the bottom cover 302 is not used to open it, so the safety is improved.

[0024] See also Figure 1 and Figure 2 The stirring structure 2 includes a motor 201 and a spiral stirring shaft 203. Two motors 201 are installed on one side of the box body 1. Two parallel spiral stirring shafts 203 are arranged inside the box body 1. One end of the spiral stirring shaft 203 is connected to the output end of the adjacent motor 201 through a coupling 202, and the other end of the spiral stirring shaft 203 is connected to the stirring crank 205. The outer wall of the stirring crank 205 is rotatably connected to the inner side of the box body 1 through a support shaft 204. It should be noted that when the two motors 201 are turned on, the two motors 201 drive the two spiral stirring shafts 203 to rotate in opposite directions. The spiral stirring shaft 203 and the stirring crank 205 adopt a special shape, so that the contact area with the raw materials is increased, the stirring and mixing is more sufficient, and the mixing quality is improved.

[0025] See Figure 2 The stirring crank 205 is in a hook shape, and the spiral stirring shaft 203 and the stirring crank 205 are integrally formed. It should be noted that compared with the welding method, the integral forming method has a smoother connection position and no welds, which makes it less likely for the raw materials to stay at the connection position and roll off, thereby ensuring the mixing quality.

[0026] See Figure 5 and Figure 7The bottom of the sliding block 3010 is connected to the fastening structure 4, and the fastening structure 4 includes a bolt 401 and a nut 402. A long cavity 403 is opened at the bottom of the slide rail 303, and the bottom of the sliding block 3010 is fixedly connected to the bolt 401, and the bottom of the bolt 401 is threadedly connected to the nut 402. The outer diameter of the bolt 401 is smaller than the width of the long cavity 403, and the outer diameter of the nut 402 is larger than the width of the slide rail 303. It should be noted that after adjusting the opening angle of the bottom cover 302, the operator holds the wrench and rotates the nut 402. The top surface of the nut 402 and the bottom of the slide rail 303 form an extrusion force, so that the nut 402 is squeezed and tightened, so that the sliding block 3010 stays inside the slide rail 303 and is not easy to slide. The bottom cover 302 is fixed at a certain opening to continue unloading, or the bottom cover 302 is fixed to the bottom area of ​​the box body 1 to prevent the internal raw material from being squeezed by gravity and causing the bottom cover 302 to open.

[0027] refer to Figure 4 and Figure 6 The special-shaped rod 301 is composed of a rocker arm 1001, a ring 1002 and a vertical rod 1003. The outer wall of the ring 1002 is fixedly connected to the rocker arm 1001 and the vertical rod 1003. The rocker arm 1001 and the vertical rod 1003 are tilted at an angle. The inside of the ring 1002 is rotatably connected to the rotating shaft 308, and the bottom end of the vertical rod 1003 rotates with the pin 309. It should be noted that during the rotation process of holding the special-shaped rod 301 by hand, the lever principle is used, and the swing fulcrum of the special-shaped rod 301 is located at the position of the rotating shaft 308, so that the operation is more labor-saving. The special-shaped rod 301 drives the vertical rod 1003 to change its angle, thereby squeezing the bottom cover plate 302 to change its opening angle.

[0028] See Figure 2 The two rocker arms 1001 located at the front and rear ends of the box body 1 are connected by a grip 307. The baffles 305 are fixedly connected to the top of the two side walls of the bottom cover 302. A placement slot 304 matching the baffle 305 is provided at the bottom of the box body 1. It should be noted that the operator can hold the grip 307 with both hands to operate. The grip 307 is cylindrical in shape, with a large hand contact area, which increases the comfort of operation. The baffle 305 blocks the unloading of raw materials from the front and rear sides, thereby preventing the raw materials from falling to the ground and causing waste of resources. The merging process of the bottom cover 302 drives the baffle 305 to the internal storage of the placement slot 304.

[0029] See Figure 2 The bottom side wall of the box body 1 is rotated to connect to the upper cover plate 5 through several second hinges 6, and the outer side of the box body 1 is fixedly connected to several L-shaped support rods 7. It should be noted that before the mixing process, the upper cover plate 5 is merged to prevent the internal raw materials from flying out during the stirring and rolling process, thereby reducing the internal carbon-containing dust particles from flying out and causing indoor environmental pollution.

[0030] Working principle: put the activated carbon proportioning raw materials into the box 1 from the top, turn on the two motors 201, and the two motors 201 drive the two spiral stirring shafts 203 to rotate in opposite directions. The spiral stirring shaft 203 and the stirring crank 205 are of special shape, so that the contact area with the raw materials is increased. After the stirring is completed, the material receiving cart is moved to the bottom of the box 1, and the operator holds one end of the special-shaped rod 301 with both hands and swings it, thereby driving the bottom cover 302 to rotate along the direction of the first hinge 306, so that the bottom of the box 1 opens a certain angle, and the mixed raw materials slide directly from the inclined bottom cover 302 to the inside of the material receiving cart. There are still mixed raw materials on the bottom cover 302, which can be swung back and forth by holding the special-shaped rod 301 up and down, so as to vibrate the bottom cover 302 up and down, so that part of the mixed raw materials remaining on the bottom cover 302 vibrate and fall, maximizing the outflow of all the mixed raw materials.
