Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixers, in particular to a concrete raw material mixing and stirring device. Background Art
[0002] It generally refers to engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete made of cement as the cementitious material, sand and stone as the aggregate; mixed with water (which may contain additives and admixtures) in a certain proportion and stirred. The mixing and stirring device is the main equipment for producing concrete. After different materials are fully mixed, the required proportion of concrete can be produced. At present, there are various concrete raw material mixing and stirring devices, but there are still some problems in their complex evolution process. First of all, it is necessary to adjust the proportions of cement, sand and gravel, and water according to actual needs. This step mostly needs to be estimated manually, resulting in deviation of the raw material proportions. At the same time, there is often residual concrete at the bottom of the inner cavity of the mixer, which is inconvenient to clean, not only wasting resources, but also affecting the next use. Therefore, we provide a concrete raw material mixing and stirring device to solve the above problems. Content of the Utility Model

A bracket is fixedly connected to the bottom of the body, a motor is installed inside the bracket, the output end of the motor is fixedly connected with a rotating shaft through a coupling, the rotating shaft is rotationally connected to the bottom wall of the body through a bearing, the top end of the rotating shaft is fixedly connected with a turntable, and a plurality of stirring blades are fixedly installed on the circular side wall of the turntable in an inclined shape. Scraping strips are fixedly connected to both sides of the outer wall of the rotating shaft, the bottoms of the two scraping strips are both attached to the bottom of the inner cavity of the body, and one end of the scraping strip is attached to the side wall of the body.
[0004] Preferably, a discharge pipe is fixedly communicated with the side wall of the body, and a valve body is installed on one side of the discharge pipe.
[0005] Preferably, the cross section of the scraping strip is triangular, and one side of the scraping strip is integrally attached to the bottom wall of the body.

[0009] The beneficial technical effects of the present utility model are as follows: The hydraulic weighing sensor can measure the weight of the body and the concrete raw materials. When each raw material is loaded, the data detected by the hydraulic weighing sensor gradually increases and is displayed on the controller. Through this, accurate proportioning of each raw material can be achieved. At the same time, the operation of the motor can drive the rotating shaft to rotate through the coupling, and the rotating shaft can drive the inclined stirring blades to revolve through the turntable. The inclined stirring blades can drive the concrete to move obliquely when rotating, making the stirring more uniform. At the same time, a triangular scraping strip is provided at the bottom wall of the body where the rotating shaft is located, which can separate the concrete on the bottom wall of the body from the body, so that it is always in a mixed motion state and will not always adhere to the body. At the same time, after the concrete is mixed, the valve body is opened so that the concrete can flow out at the discharge pipe. When the concrete in the body is almost used up, the scraping strip can also scrape the remaining concrete centrifugally when rotating, so that all the remaining concrete can be moved to the discharge pipe and discharged, thus eliminating the need for complex cleaning of the body after use, making the overall process of proportioning, mixing and cleaning more convenient.

[0013] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.
[0014] The utility model provides a concrete raw material mixing and stirring device, which comprises a base 1. Above the base 1, there is a machine body 2. A plurality of hydraulic weighing sensors 3 are annularly and equidistantly installed on the top of the base 1. At the top of the test ends of the plurality of hydraulic weighing sensors 3, there are connecting pads 4, and the plurality of pads 4 are fixedly connected to the bottom of the machine body 2. In actual use, the number of the hydraulic weighing sensors 3 is four. The hydraulic weighing sensors 3 can detect the combined weight of the machine body 2 and the raw materials. The hydraulic weighing sensors 3 are connected to a controller, which can zero and reset while displaying the value, thus facilitating the adjustment of the proportion of the concrete raw materials. At the bottom of the machine body 2, there is a fixedly connected support 5. Inside the support 5, there is a motor 6. The output end of the motor 6 is fixedly connected to a rotating shaft 7 through a coupling. The operation of the motor 6 can drive the rotating shaft 7 to rotate. The rotating shaft 7 is rotationally connected to the bottom wall of the machine body 2 through a bearing. At the top end of the rotating shaft 7, there is a fixedly connected turntable 8. On the circular side wall of the turntable 8, a plurality of stirring blades 9 are fixedly installed in an inclined shape. The turntable 8 is used for connecting the rotating shaft 7 and the stirring blades 9. On both sides of the outer wall of the rotating shaft 7, there are fixedly connected scraping bars 10. The bottoms of the two scraping bars 10 are attached to the bottom of the inner cavity of the machine body 2, and one end of the scraping bar 10 is attached to the side wall of the machine body 2. The design of the scraping bar 10 can separate the concrete on the bottom wall of the machine body 2 from the machine body 2, so that it is always in a mixed motion state and will not always adhere to the machine body 2.
[0015] Specifically, a discharge pipe 11 is fixedly communicated with the side wall of the machine body 2. On one side of the discharge pipe 11, there is a valve body 12. The concrete can be discharged at the discharge pipe 11, and the valve body 12 can close the discharge pipe, which is convenient for stirring and mixing.
[0016] Specifically, the cross-section of the scraping bar 10 is triangular, and one side of the scraping bar 10 is integrally attached to the bottom wall of the machine body 2. The triangular scraping bar 10 can separate the concrete on the bottom wall of the machine body 2 from the machine body 2, so that it is always in a mixed motion state and will not always adhere to the machine body 2. At the same time, after the concrete is mixed, the valve body 12 is opened so that the concrete can flow out at the discharge pipe 11. When the concrete in the machine body 2 is almost used up, the scraping bar 10 can also scrape the remaining concrete in a centrifugal manner during rotation, so that all the remaining concrete can be moved to the discharge pipe 11 for discharge.
[0017] Specifically, a groove is processed at the connection between the pad 4 and the hydraulic weighing sensor 3. The test end of the hydraulic weighing sensor 3 is placed inside the groove of the pad 4. The design of the groove can make the machine body 2 more stable on the hydraulic weighing sensor 3 and play a role in limiting the position.
[0018] Specifically, a circular cavity 13 is processed inside the base 1, and both the support 5 and the motor 6 are placed inside the circular cavity 13. The design of the circular cavity 13 can make the motor 6 and the support 5 located inside it, reducing the overall use space of the device.
[0019] Specifically, the top opening of the machine body 2 is designed with an inwardly retracted closing opening. When the concrete is being stirred, a certain centrifugal force will occur. The closing opening design can prevent the concrete from being thrown out of the inner cavity of the machine body 2.
[0020] For those skilled in the art, all the electrical components and parts in this case are common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. As long as the models are adapted to this solution and can operate normally, all the electrical components in this case are connected to their adapted power supplies through wires. And according to the actual situation, a suitable controller is selected to meet the control requirements. For the specific connection and control sequence, the electrical connection should be completed according to the sequential working order among the electrical components in the following working principle. The detailed connection means are well-known techniques in the art, and no further description of the electrical control will be given.
[0021] Working principle: When using this mixing and stirring device, it can be placed entirely on a horizontal ground. The hydraulic weighing sensor 3 is reset to zero through the controller. Then, sand and gravel are loaded into the inner cavity of the machine body 2, which increases the overall weight of the machine body 2 plus the sand and gravel. The hydraulic weighing sensor 3 can obtain the weight increase data through the display after detection. Then, an appropriate amount of cement is added, and the weight increase data is obtained again. The appropriate amount of cement can be taken out or loaded according to the actual data. At this time, the cement and sand and gravel can be mixed for the first time according to the situation to make them fully mixed. Finally, an appropriate amount of water is loaded. The weight can be displayed through the hydraulic weighing sensor 3, so that the ratio among the three is more controllable, and the quality of the obtained concrete is higher. After the three are filled, the user can start the motor 6. The operation of the motor 6 can drive the rotating shaft 7 to rotate through the coupling. The rotating shaft 7 can drive the inclined stirring blades 9 to revolve through the turntable 8. The inclined stirring blades 9 can drive the concrete to move obliquely when rotating, making the stirring more uniform. At the same time, a triangular scraping strip 10 is arranged at the bottom wall of the machine body 2 where the rotating shaft 7 is located, which can separate the concrete on the bottom wall of the machine body 2 from the machine body 2, so that it is always in a mixed motion state and will not always adhere to the machine body 2. At the same time, after the concrete is mixed, the valve body 12 is opened to discharge the concrete at the discharge pipe 11. When the concrete in the machine body 2 is almost gone, the scraping strip 10 can also scrape the remaining concrete centrifugally under its own rotation, so that all the remaining concrete can be moved to the discharge pipe 11 for discharge. Thus, there is no need to perform complex cleaning on the used machine body 2, making the overall proportioning, mixing, and cleaning processes simpler and more convenient to use.
