Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, in particular to a mixing device for self-leveling construction. Background Art

[0002] Self-leveling floor refers to the surface layer formed by using materials with automatic leveling or slightly auxiliary leveling function on the base layer and paving after on-site mixing. Common self-leveling floors include mud-based self-leveling floors, resin self-leveling floors, and resin-cement composite mortar self-leveling floors. Self-leveling materials need to be mixed with other materials when used, so a special mixing device must be used.

[0003] For example, a Chinese utility model patent with announcement number CN218398782U discloses a mixing device for self-leveling construction. The device, through the setting of a screen plate assembly, can prevent agglomerated materials with too large particles from falling directly from the discharge port during the feeding process, thereby better achieving the purpose of improving the mixing effect.

[0004] However, when the device is actually used, the agglomerated materials with oversized particles that are screened out still remain on the screening component, and the device lacks a structure that can squeeze and crush the agglomerated materials with oversized particles. As a result, the agglomerated materials with oversized particles are easily accumulated and clog the screening component, thereby reducing the subsequent filtering effect on the self-leveling material.

[0005] In summary, there is a need for a mixing device for self-leveling construction that can crush large particles of material in a timely manner. Utility Model Content

The top of the vertical rod 107 is slidably connected to the U-shaped bracket 104, and the first spring 108 is sleeved on the outside of the vertical rod 107. The discharge pipe 2 is symmetrically provided with notches and is slidably connected to the connecting rod 103. The width of the extrusion plate 101 is consistent with the width of the filter plate 3, which can ensure the thoroughness of crushing large-particle agglomerated materials. The sum of the areas of the two groups of baffles 102 is larger than the cross-sectional area of ​​the discharge pipe 2, which can prevent the material from falling to the other side of the extrusion plate 101 during extrusion and affecting its return, thereby ensuring the normal operation of the device;

[0031] The anti-adhesion component includes four groups of gears 201 symmetrically rotatably connected on both sides of the mixing barrel 1, a U-shaped bracket 104 is provided with teeth 202 on one side corresponding to the gear 201 and meshingly connected with the gear 201, one end of the gear 201 is coaxially fixedly connected with a cam 203, connecting frames 204 are provided on both sides of the mixing barrel 1, and a telescopic rod 205 is symmetrically fixedly connected between the connecting frame 204 and the mixing barrel 1, and a second spring 206 is sleeved on the outside of the telescopic rod 205. A percussion hammer 207 is also fixedly connected to the connecting frame 204, and the telescopic rod 205 is composed of a sleeve and a sleeve rod one end of which is movably connected to the inside of the sleeve.

[0032] The U-shaped bracket 104 is also rotatably connected to a rotating shaft 4, and the lower part of the rotating shaft 4 extends to the interior of the mixing barrel 1. The top of the mixing barrel 1 is rotatably connected to a bevel gear ring 5 and is movably connected to the rotating shaft 4. The top of the mixing barrel 1 is fixedly connected to a motor, and the rotor end of the motor is coaxially fixedly connected to a bevel gear 6 and meshingly connected to the bevel gear ring 5. The outside of the rotating rod and the motor rotor are fixedly sleeved with transmission gears, and the two sets of transmission gears are connected by a transmission toothed belt transmission. The outer side of the lower part of the rotating shaft 4 is equidistantly circumferentially fixed with stirring rods 7, which can increase the stirring range, thereby increasing the uniformity of mixing the self-leveling material. Limiting grooves are symmetrically provided on the outside of the rotating shaft 4, and the inner side of the bevel gear ring 5 is symmetrically fixedly connected to the limiting blocks and is slidably connected between the limiting grooves, so that the rotating shaft 4 can move vertically without affecting the normal transmission between the rotating shaft 4 and the bevel gear ring 5.

[0033] The implementation principle of a mixing device for self-leveling construction in the embodiment of the present application is as follows: first, the material is added into the mixing barrel 1 through the feeding pipe, and then the motor is started. The motor will drive the bevel gear 6 to rotate, and the meshing action between the bevel gear 6 and the bevel gear ring 5 can be used to drive the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the stirring rod 7 to rotate, so that the material can be stirred and mixed. At the same time, the transmission cooperation between the transmission gear and the transmission toothed belt can also drive the eccentric wheel 106 to rotate. The rotation of the eccentric wheel 106 can regularly squeeze the U-shaped bracket 104. When the U-shaped bracket 104 is compressed, the U-shaped bracket 104 will move vertically downward. By using the sliding cooperation between the limit block and the limit groove, the rotating shaft 4 will be driven to move downward together, thereby driving the stirring rod 7 to move vertically downward to mix the material in the lower part of the internal cavity of the mixing barrel 1. When the eccentric wheel 106 rotates away from the U-shaped bracket 104, the sliding cooperation between the vertical rod 107 and the mixing barrel 1 and the elastic action of the first spring 108 can be used to drive the rotating shaft 4 to reset, so as to The stirring range of the device for the material is improved, thereby improving the mixing effect. At the same time, during the vertical movement of the U-shaped bracket 104, the hinged effect between the U-shaped bracket 104 and the connecting rod 103 and the connecting rod 105 is utilized to push the two groups of extrusion plates 101 to move regularly toward or away from each other, so that the large-particle agglomerated materials filtered out by the filter plate 3 can be squeezed and crushed, and the meshing action of the gear 201 and the teeth 202 is utilized to drive the gear 201 to rotate while the U-shaped bracket 104 moves vertically, and the rotation of the gear 201 drives the cam 203 to rotate, and the rotation of the cam 203 can regularly squeeze the connecting bracket 204, and under the cooperation of the telescopic effect of the telescopic rod 205 and the elastic effect of the second spring 206, it can drive the knocking hammer 207 to regularly knock on the barrel wall of the mixing barrel 1, thereby avoiding the problem of self-leveling material sticking to the barrel wall and causing residue, and finally the mixed material will be discharged through the discharge pipe 2.

[0034] In addition, a further improvement is that the bottom end of the vertical rod 107 is fixedly connected to a limit plate, which can prevent the vertical rod 107 from being separated from the mixing barrel 1.
