[0043] In another embodiment of the present application, please refer to Figures 1 to 5 , the adjustment mechanism includes a material unloading box 110 movably connected to the frame plate 101, the lower measuring cup 142 extends into the material unloading box 110 and is connected to the material unloading box 110, the moving direction of the material unloading box 110 relative to the frame plate 101 is parallel to the sliding direction of the lower measuring cup 142 relative to the upper measuring cup 141, and the bottom of the material unloading box 110 is provided with a discharge port 111 directly opposite to the port of the lower measuring cup 142. According to the above structure provided in this embodiment, when the material unloading box 110 movably connected to the frame plate 101 moves relative to the frame plate 101, it can drive the lower measuring cup 142 to move relative to the upper measuring cup 141, so that there is no need to set a separate driving structure for the lower measuring cup 142, and the material unloading box 110 set on the frame plate 101 can be used to receive the material in the measuring cup 104 multiple times on the one hand, and can also be better adapted to the external packaging structure such as a packaging bag, etc., which is conducive to making the large-capacity particle metering device provided in the embodiment have higher working efficiency.

According to the above structure provided in this embodiment, the material box 110 having a tapered shape can be more convenient for the material in the material box 110 to be discharged from the discharge port 111.

[0045] In another embodiment of the present application, please refer to Figures 1 to 5 The regulating mechanism further includes a discharge cylinder 112 hinged inside the discharge box 110, the output end of the discharge cylinder 112 is hinged on the discharge door 105 and is used to drive the discharge door 105 to open or close, and the sensor 109 is also communicatively connected to the discharge cylinder 112.

The end of the worm 115 is connected to an adjusting handwheel 117. According to the above structure provided in this embodiment, when the worm 115 rotates, the worm wheel 116 and the driving nut 114 connected to the worm wheel 116 can be driven to rotate, so that the screw 113 threadedly connected to the driving nut 114 can move along its own axial direction relative to the frame plate 101, which can achieve the movement effect of the unloading box 110 and facilitate the precise adjustment effect of the lower measuring cup 142 and the upper measuring cup 141.

In this way, when the transmission nut 114 rotates with the worm gear 116, the screw rod 113 can be moved axially. According to the above structure provided in the present embodiment, the thrust bearings 118 arranged on both sides of the frame plate 101 can form a more stable rotation support for the transmission nut 114, that is, when the locking nut 143 is screwed on the upper end of the transmission nut 114 and its pressing force on a group of thrust bearings 118 directly abutting against it is adjusted, on the one hand, the seat ring end faces of a group of thrust bearings 118 located above the frame plate 101 abut against the upper end face of the frame plate 101, and the shaft ring end face abuts against the locking nut 143; on the other hand, the seat ring of a group of thrust bearings 118 located below the frame plate 101 abuts against the lower end of the frame plate 101, and the shaft ring abuts against the upper end face of the worm gear 116, thereby completing the axial limitation of the transmission nut 114 and maintaining smooth rotation, which is beneficial to further improve the sliding stability during adjustment between the lower measuring cup 142 and the upper measuring cup 141.

[0048] In another embodiment of the present application, please refer to Figures 1 to 5The rotating arm 106 is also connected with a material-driving plate 119 that abuts against the bottom of the silo 102 and is slidably connected to the silo 102.
