[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See also Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a particle mixing device with adjustable discharging efficiency according to the first embodiment of the utility model. Figure 2 This is a schematic diagram of the connection between the mixing tank and the discharge box of the first embodiment of the utility model. Figure 3 It is a structural schematic diagram of the discharge regulating device of the first embodiment of the utility model.

[0021] The utility model provides a particle stirring device with adjustable discharge efficiency: comprising a stirring tank 101, a bracket 102 and a stirring device, and also comprising a discharge adjustment device, wherein the discharge adjustment device comprises a discharge box 104, a discharge plate 105, an adjustment shaft 106 and a driving assembly, wherein the driving assembly comprises a gear 107 and a moving component, wherein the moving component comprises a rack 108, a connecting rod 109 and a pushing gas rod 110. The above scheme solves the problem that although the above scheme can realize the adjustment of the particle discharge rate, the particles after stirring are easily accumulated on the upper end surface of the plug, so that the particles cannot be completely discharged. It can be understood that the present scheme can also be used to solve the problem of stirring the raw material particles.

[0022] In this embodiment, by changing the size of the gap between the discharge plates 105 between each two adjacent groups, the discharge rate of the raw material particles is adjusted, and the accumulation of raw material particles in the discharge box 104 and the inability to be completely discharged are avoided.

[0023] The discharge box 104 is fixedly mounted on the mixing tank 101 and is located on a side of the mixing tank 101 close to the bracket 102. The discharge box 104 is communicated with the mixing tank 101. The adjusting shaft 106 is rotatably mounted in the discharge box 104 through the driving assembly and passes through the discharge box 104. The discharge plate 105 is fixedly mounted on the adjusting shaft 106 and is located in the discharge box 104. The upper part of the mixing tank 101 is square and the lower part is prism-shaped. The interior of the mixing tank 101 is hollow and the lower part is open. The bottom of the discharge box 104 is open. The number of the discharge plates 105 is consistent with the number of the adjusting shafts 106, and the specific number depends on the amount of raw material particles. 05 is in a flat position when not in use, and can just block the discharge box 104. The adjusting shaft 106 is installed on the discharge box 104 through a bearing. During discharge adjustment, under the drive of the driving component, multiple groups of the adjusting shafts 106 rotate and drive multiple groups of the adjusting plates to rotate, so that the gap between the discharge plates 105 between each two adjacent groups is opened, and the raw material particles can be discharged through the gap between the discharge plates 105. At the same time, with the change of the rotation angle of the adjusting shaft 106, the gap between the discharge plates 105 between each two adjacent groups also increases or decreases, thereby realizing the adjustment of the discharge rate of the raw material particles and avoiding the accumulation of raw material particles in the discharge box 104, which causes the phenomenon of incomplete discharge.

[0024] Secondly, the gear 107 is fixedly mounted on the adjusting shaft 106 and is located outside the discharge box 104; the movable member drives the gear 107 to rotate, the number of the gears 107 is the same as the number of the adjusting shafts 106, and are all distributed at the ends of the adjusting shafts 106, and the movable member drives multiple groups of the gears 107 to rotate at the same time, so that the gear 107 drives multiple groups of the adjusting shafts 106 to rotate, thereby achieving a rotation effect on the adjusting shafts 106.

[0025] Again, the pushing air rod 110 is fixedly installed on the outside of the discharge box 104; the connecting rod 109 is fixedly connected to the output end of the pushing air rod 110; the rack 108 is fixedly installed on the connecting rod 109 and meshes with the gear 107. The pushing air rod 110 is fixed to the outer edge of the discharge box 104 by screws. The connecting rod 109 is L-shaped. The rack 108 meshes with multiple groups of gears 107 at the same time. The pushing air rod 110 drives the rack 108 to move by pushing the connecting rod 109. The movement of the rack 108 can drive multiple groups of gears 107 to rotate at the same time by meshing with multiple groups of gears 107, thereby realizing the driving of the gears 107.

[0026] In this embodiment, when in use, the raw material particles are injected into the stirring tank 101 through the feeding pipe 103, and then the raw material particles are stirred by the stirring device. After the stirring is completed, the material is discharged, and the pushing gas rod 110 is started to push the connecting rod 109 to move. The movement of the connecting rod 109 pushes the rack 108 fixedly connected thereto to move. The rack 108 is meshed with multiple groups of gears 107 at the same time. The movement of the rack 108 drives the multiple groups of gears 107 to rotate at the same time. The rotation of the gear 107 drives the adjusting shaft 106 to rotate. The adjusting shaft 106 is meshed with the gears 107. The discharge plates 105 in the discharge box 104 are fixedly connected, and the rotation of the adjusting shaft 106 drives multiple groups of the discharge plates 105 to rotate simultaneously, so that the gap between each two adjacent groups of the discharge plates 105 is opened, and the raw material particles can be discharged through the gap between the discharge plates 105. At the same time, with the change of the rotation angle of the adjusting shaft 106, the gap between each two adjacent groups of the discharge plates 105 also increases or decreases accordingly, thereby realizing the adjustment of the discharge rate of the raw material particles and avoiding the accumulation of raw material particles in the discharge box 104, which causes the phenomenon of incomplete discharge.

[0027] The second embodiment of the present application is:

[0029] In this embodiment, the stirring column 201 is driven by the rotating assembly to rotate the cross bar 202 , thereby achieving a stirring effect on the raw material particles through the rotation of the cross bar 202 .

[0030] Among them, the stirring column 201 is rotatably installed in the stirring tank 101 through the rotating component; the cross bar 202 is fixedly installed on the stirring column 201, the cross section of the stirring column 201 is square, and the cross bar 202 is symmetrically arranged on both sides of the stirring column 201, with four groups of cross bars 202 on each side. During stirring, the stirring column 201 is driven to rotate by the rotating component, and the rotation of the stirring column 201 drives the cross bar 202 to rotate, so that the stirring effect on the raw material particles is achieved through the rotation of the cross bar 202.

[0031] Secondly, the motor 204 is fixedly installed in the stirring tank 101; the rotating shaft 203 is fixedly installed on the output shaft of the motor 204 and is fixedly connected to the stirring column 201. The motor 204 is fixed to the inner top of the stirring tank 101 by bolts, and the rotating shaft 203 is welded on the output shaft of the motor 204. The rotating shaft 203 coincides with the axis of the stirring column 201. The motor 204 drives the rotating shaft 203 to rotate, and the rotation of the rotating shaft 203 drives the stirring column 201 to rotate, thereby realizing the driving of the stirring column 201.

[0032] In this embodiment, during stirring, the motor 204 drives the rotating shaft 203 to rotate, the rotation of the rotating shaft 203 drives the stirring column 201 to rotate, and the rotation of the stirring column 201 drives the cross bar 202 to rotate, thereby achieving a stirring effect on the raw material particles through the rotation of the cross bar 202.
