Description

Technical Field

[0001] The utility model relates to the technical field of dry-mix mortar mixing, in particular to a dry-mix mortar mixer. Background Art

[0002] In the field of dry-mix mortar production, mixers are indispensable equipment. Their main function is to mix various dry powder raw materials in a certain proportion to prepare dry-mix mortar that meets specific performance requirements. Traditional dry-mix mortar mixers usually use a blade-type stirring mechanism, which uses rotating stirring blades to stir and mix the powder in the tank.

[0003] However, this method of stirring by only using the stirring shaft to drive the stirring blade has some inherent disadvantages. First, due to the effect of gravity, the powder tends to settle at the bottom of the stirring tank, forming a certain amount of accumulation. In this case, it is difficult to fully mix the powder at the bottom with the powder at the top by the stirring action of the stirring blade alone, resulting in low stirring efficiency and requiring a long stirring time to achieve the desired mixing effect.

[0004] Secondly, there is a certain gap between the stirring blade and the tank body to avoid friction and wear between the stirring blade and the tank body. However, the existence of this gap also makes it easy for part of the powder to be retained in the gap during the stirring process, and it cannot be effectively stirred and mixed, thus affecting the uniformity of mixing.

[0005] Finally, traditional dry-mix mortar mixers usually cannot rotate the tank body, which makes it difficult to clean the tank body. Since the powder easily adheres to the inner wall of the tank body during the mixing process, if the tank body cannot be rotated, it is difficult to thoroughly clean the inner wall of the tank body, resulting in the residual powder affecting the mixing of the new batch. Therefore, the traditional dry-mix mortar mixer that only relies on stirring blades for stirring has certain shortcomings in terms of stirring efficiency, mixing uniformity and cleaning convenience. In order to solve these problems, it is necessary to improve and optimize the existing mixer to improve its stirring efficiency and mixing uniformity, while facilitating cleaning and maintenance. Utility Model Content

[0006] The utility model aims to provide a dry mortar mixer, which is used to solve the problem that the prior art only relies on stirring blades to stir powder, resulting in poor stirring effect and low powder mixing uniformity.

[0007] The utility model solves the above problems through the following technical solutions:

[0008] A dry-mix mortar mixer comprises: a bracket, a mixing drum, a mixing shaft and a controller; a first motor and a second motor are arranged on the bracket, an output shaft of the first motor is rotationally connected to the mixing drum, a reducer is arranged between the output shaft and the mixing drum, the mixing shaft passes through the mixing drum, one end of the mixing shaft is rotationally connected to the output shaft of the second motor, and the other end extends into the mixing drum, at least two groups of mixing blades are staggered and symmetrically arranged on the mixing shaft; the controller drives the first motor to work, driving the mixing drum to rotate forward, and the controller drives the second motor to work, driving the mixing shaft to rotate reversely.

[0009] Furthermore, the mixing drum body is provided with an inlet and outlet for feeding and discharging materials, and a cover plate is provided at the inlet and outlet.

[0010] Furthermore, the forward rotation of the mixing drum and the reverse rotation of the mixing shaft are performed simultaneously or separately.

[0011] Furthermore, a brush head for cleaning is snap-connected to the stirring blade.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] (1) The utility model realizes double stirring of powder by driving the stirring drum to rotate forwardly through the first motor and driving the output shaft to rotate reversely through the second motor, thereby avoiding the problem of ineffective stirring due to the gap between the stirring blade and the stirring drum, thereby improving the stirring efficiency.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] In the following description, the terms "first\second\third" and the like are only used to distinguish similar objects and do not represent a specific order for the objects. It is understandable that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0020] Example:

[0021] Combined with Figure 1 As shown, a dry-mix mortar mixer comprises: a bracket 3, a mixing drum 4, a mixing shaft 7 and a controller; a first motor 1 and a second motor 2 are provided on the bracket 3, the output shaft of the first motor 1 is rotatably connected to the mixing drum 4, wherein a reducer 6 is further provided between the output shaft and the mixing drum 4, the mixing shaft 7 passes through the mixing drum 4, one end of the mixing shaft 7 is rotatably connected to the output shaft of the second motor 2, and the other end extends into the mixing drum 4, wherein at least two groups of mixing blades 5 are staggered and symmetrically provided on the mixing shaft 7; the controller drives the first motor 1 to work, driving the mixing drum 4 to rotate forward, and the controller drives the second motor 2 to work, driving the mixing shaft 7 to rotate reversely.

[0022] It should be noted that the bracket 3 serves as the supporting structure of the entire mixer. The first motor 1 and the second motor 2 are installed on the bracket 3. The two motors are responsible for driving the movement of the mixing drum 4 and the mixing shaft 7 respectively. The output shaft of the first motor 1 is directly connected to the mixing drum 4. When the first motor 1 is started, it drives the mixing drum 4 to rotate through the output shaft. In order to ensure that the mixing drum 4 can rotate at an appropriate speed and torque, a direct-connected reducer is also arranged between the output shaft and the mixing drum 4, which is used to convert the high-speed and low-torque output of the motor into a low-speed and high-torque output, thereby providing sufficient power to drive the powder in the mixing drum 4 to mix. The direct-connected reducer directly connects the reducer 6 and the mixing drum 4, realizes a more compact structural design, reduces the use of transmission chains or belts, improves transmission efficiency, reduces energy loss, and simplifies the operation and maintenance of the equipment. The mixing shaft 7 runs through the entire mixing drum 4 and is connected to the output shaft of the second motor 2. When the second motor 2 is working, it drives the mixing shaft 7 to rotate. The rotation direction of the mixing shaft 7 is opposite to that of the mixing drum 4. This counter-rotating design can increase the stirring effect of the powder during the mixing process, ensuring that the powder can be mixed together more quickly and evenly. At least two groups of stirring blades 5 are also provided on the stirring shaft 7, each group of stirring blades 5 includes two blades with sliding symmetry, and these stirring blades 5 are arranged in a staggered and symmetrical manner. The shape and number of the blades can be designed according to actual needs. When the stirring shaft 7 rotates, the stirring blades 5 will push the powder to the center of the mixing drum 4 from all directions, further promoting the mixing effect; this design can ensure that there will be no dead corners or uneven mixing of the powder during the mixing process. The controller is responsible for controlling the operation of the first motor 1 and the second motor 2. Through the controller, the rotation speed, rotation direction and rotation time of the mixing drum 4 and the stirring shaft 7 can be accurately controlled, so as to achieve efficient mixing of the powder, and ensure that the final mixed powder has consistent quality and performance, so as to meet various construction needs.

[0023] Combined with Figure 2 As shown, the mixing drum 4 is provided with an inlet and outlet for feeding and discharging materials, and the inlet and outlet are provided with a cover plate 8. It should be noted that the forward rotation of the mixing drum 4 and the reverse rotation of the mixing shaft 7 are performed simultaneously or separately.

[0024] It should be noted that the mixing drum 4 is used to contain powders and provide a space so that the powders can be evenly mixed therein. In order to achieve this function and to conveniently add raw materials and take out finished products during the mixing process, an inlet and outlet for feeding and discharging is specially designed on the body of the mixing drum 4. The inlet and outlet is an opening on the body of the mixing drum 4, which is used to add (feed) the powder raw materials to be mixed into the mixing drum 4, and to take out (discharge) the mixed powder from the mixing drum 4 after the mixing is completed. It is like the lid of a storage box, and you will open this lid when you need to put in or take out items. Similarly, the inlet and outlet is like this "lid", except that it is used for the entry and exit of powders, and it allows the operator to open it when necessary, so as to add the powder raw materials to be mixed into the mixing drum 4, or to take out the evenly mixed powder after the mixing is completed. At the same time, during the mixing process, in order to ensure the safety of operation and prevent accidental splashing of powder, a cover plate 8 for sealing the inlet and outlet of the mixing drum 4 is provided at the inlet and outlet. The cover plate 8 is fixedly connected to the drum body by a nut 9, which is usually a plate-shaped object matching the size of the inlet and outlet, which can prevent the splashing of powder during the mixing process and ensure that the powder in the mixing drum 4 will not splash due to centrifugal force or other factors during the mixing process, thereby protecting the safety of the operator and the cleanliness of the on-site environment. This design greatly improves the convenience and work efficiency of the mixer.

[0025] The stirring blade 5 is buckled with a brush head for cleaning.

[0026] It should be noted that in the dry mortar mixer, the main function of the stirring blade 5 is to push the powder to mix when the stirring shaft 7 rotates. In order to further improve the mixing effect and reduce the residue in the mixing process, each group of stirring blades 5 is provided with a brush head connected by a buckle. The brush head is a cleaning tool made of bristles or similar materials. Its main function is to remove dirt or residues attached to the surface of an object by friction of the bristles. For example, the toothbrushes and dishwashing brushes we use in daily life have a brush head part, and these brush heads clean teeth or dishes by friction of the bristles. In the dry mortar mixer, the function of the brush head is to clean the powder residue on the inner wall of the mixing drum 4. It is connected to the stirring blade 5 by a buckle, which is convenient for replacement or cleaning when necessary. When the stirring shaft 7 drives the stirring blade 5 to rotate, the brush head will move with the stirring blade 5, and its bristle part will contact the inner wall of the mixing drum 4; because the bristles have a certain elasticity and hardness, they can effectively scrape and clean the powder residue on the inner wall of the mixing drum 4 during the mixing process. This not only improves the uniformity of mixing, but also reduces the workload of additional cleaning of the mixing drum 4 after mixing. Through continuous scraping and cleaning by the brush head on each set of stirring blades 5, the inner wall of the mixing drum 4 can be kept relatively clean, thereby improving the working efficiency and service life of the mixer.

[0027] Working principle: During operation, the controller drives the first motor 1 to drive the mixing drum 4 to rotate forward through the reducer 6 and drives the second motor 2 to drive the mixing shaft 7 to rotate reversely. At least two groups of mixing blades 5 are staggered and symmetrically arranged on the mixing shaft 7, so as to achieve uniform mixing of the powder in the mixing drum 4. At the same time, the brush head snap-connected to the mixing blade 5 can effectively scrape and clean the powder residue on the inner wall of the mixing drum 4 during the mixing process.

[0028] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
