Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and more specifically, to a mortar mixer. Background Technology

[0002] Mortar mixing is a production process that involves mixing sand, gravel, or other raw materials with the addition of other materials to form a mixed material.

[0003] The mortar mixing process basically requires mixing by a mixer. Existing mixers usually have multiple mixing structures at the mixing end, but these structures usually require the mixer to rotate at high speed to move the mortar, resulting in low mixing efficiency and generally poor uniformity of the mixture.

[0004] Therefore, a new solution is needed to supplement the existing mixer category. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mortar mixer.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mortar mixer, including a driver, a rotating shaft, and a mixing tank. A protective sleeve is fixedly installed on the rotating shaft, and a plurality of mixing blades are fixedly installed on the protective sleeve. The mixing blades are evenly distributed on the protective sleeve and are arranged in two rings. A positioning sleeve is fitted on the outer extension area of ​​the plurality of mixing blades, and a plurality of guide strips are respectively provided on the inner and outer walls of the positioning sleeve. The positioning sleeve and the mixing blades are fixedly connected to each other. The driver drives the rotating shaft. The mixing tank is installed on the driver, and the rotating shaft extends into the mixing tank.

[0007] The present invention is further configured such that: the positioning sleeve includes several vertical pieces and a ring that are fixed to each other, and the positioning sleeve as a whole is formed by the vertical pieces and is fixedly connected to the stirring plate.

[0008] The present invention is further configured such that: the cross-section of the guide strip forms a parallelogram, the guide strip is disposed in the region of the same long side of the vertical piece, and the guide strips on the same vertical piece alternate with each other.

[0009] The present invention is further configured such that: the stirring plate is configured as an arc surface, and a through opening is provided in the middle position of the stirring plate.

[0010] The present invention is further configured such that: the vertical piece has a notch on the long side where the guide strip is provided, and the notch is formed in an arc shape.

[0011] The present invention is further configured such that both the stirring blade and the vertical blade abut against the inner bottom of the mixing tank.

[0012] In summary, the present invention has the following beneficial effects: during the mortar mixing process, the mortar can form a circulation that rises from the center of the mixing bucket and flows from the bucket wall area to the bottom under the action of the mixing blades, thereby forming a mortar circulation flow. At the same time, the guide strip set on the positioning sleeve promotes the mutual flow of mortar material in the inner and outer areas of the positioning sleeve, thus accelerating the mixing process.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A mortar mixer, such as Figures 1-4As shown, the device includes a driver 1, a rotating shaft 2, and a mixing tank 3. A protective sleeve 4 is fixedly mounted on the rotating shaft 2, and several stirring blades 5 are fixedly mounted on the protective sleeve 4. The stirring blades 5 are evenly distributed on the protective sleeve 4 and arranged in two rings. The driver 1 drives the rotating shaft 2. The mixing tank 3 is mounted on the driver 1, and the rotating shaft 2 extends into the mixing tank 3. The driver 1 drives the rotating shaft 2 to rotate, causing the rotating shaft 2 to drive the stirring blades 5 to rotate through the protective sleeve 4. This causes the stirring blades 5 to agitate and mix the raw materials in the mixing tank 3, ultimately resulting in a mixture. The stirring blades 5 are arc-shaped, with a through-hole 7 in the middle. The arc shape of the stirring blades 5 allows the raw materials near the protective sleeve 4 and the stirring blades 5 to be lifted away from the bottom of the mixing tank 3 during operation. Simultaneously, the lifted raw materials flow from the area near the tank wall to the bottom of the mixing tank 3, forming a circulating flow path for the raw materials and thus achieving circulating mixing. A positioning sleeve 6 is fitted over the outer region of the 5, and several guide strips 10 are respectively provided on the inner and outer walls of the positioning sleeve 6. The positioning sleeve 6 is fixedly connected to the stirring blade 5. The positioning sleeve 6 fixes several stirring blades 5 on the side away from the protective sleeve 4. At the same time, it can guide the flow direction of the raw materials. Most of the flow process away from the bottom of the barrel is limited by the positioning sleeve 6, so that more raw materials can follow the flow process driven by the stirring blades 5 to achieve the mixing effect. The guide strips 10 are parallelograms and are set on the same long side of the vertical blade 8. The guide strips 10 on the same vertical blade 8 alternate with each other. Under the shape restriction formed by the stirring blades 5, the rotating shaft 2 is restricted to unidirectional rotation. The guide strips 10 on the vertical blade 8 are also set on the long side of the front end of the vertical blade 8 in the direction of travel. The alternating guide strips 10 can make the material push out of the positioning sleeve 6 area or push into the positioning sleeve 6 area under the push of the corresponding guide strips 10, thus accelerating the mixing of materials.

[0020] The positioning sleeve 6 includes several vertical pieces 8 and rings 9 that are fixed to each other. The positioning sleeve 6 is formed by the vertical pieces 8 and is fixedly connected to the stirring pieces 5. The vertical pieces 8 are used to fix each other to the stirring pieces 5 in the vertical direction. Each vertical piece 8 can be fixed to two stirring pieces 5. The rings 9 are set between the stirring piece 5 area away from the bottom of the mixing tank 3 and the area of ​​the two layers of stirring pieces 5. The number of rings 9 needs to be determined by the user. The more rings 9 there are, the better the circulation of raw materials can be formed. The vertical piece 8 has a notch 11 on the long side where the guide strip 10 is set. The notch 11 is formed in an arc shape. The notch 11 makes the vertical piece 8 form an acute angle at the notch 11. This allows the vertical piece 8 to form a buffer when it moves, reducing the wear caused by the collision between the end of the vertical piece 8 near the bottom of the mixing tank 3 and the mortar material. The stirring pieces 5 and the vertical pieces 8 both abut against the inner bottom of the mixing tank 3. The abutment of the stirring pieces 5 and the vertical pieces 8 against the bottom of the tank allows the material at the bottom of the tank to be lifted upward, reducing the sedimentation at the bottom of the tank.
