Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete production, in particular to a powder material feeding mechanism for a concrete mixing station. Background Art
[0002] Concrete mixing refers to the process of mixing raw materials such as cement, sand, aggregate and water to form concrete with a certain strength and plasticity. As an important building material, concrete plays a vital role in construction projects. Concrete mixing is usually done by a concrete mixer or a concrete mixer truck. During the mixing process, the raw materials will be evenly mixed to give the concrete a uniform texture and performance. The time, speed and method of mixing will affect the quality and performance of the concrete. Concrete mixing is an important link in the construction process, which directly affects the structural strength and performance of the building. Through scientific and reasonable mixing technology and control methods, the quality of concrete can be ensured to be stable and meet the requirements of engineering design and use.
[0003] Concrete is a mixed product that requires a variety of raw materials to be mixed. As the powder enters, it will cause huge dust. When the existing powder feeding mechanism is in use, the powder will collide with the inner wall of the mechanism when it enters, causing the powder to fly. The feeding mechanism cannot handle it in time, which not only causes the powder to dissipate with the airflow, but also causes corresponding air pollution to the environment.
[0004] Therefore, it is urgent to provide a powder feeding mechanism for a concrete mixing station to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is that powder will collide with the inner wall of the main body when feeding, thereby generating dust, causing the dust to fly into the air, causing air pollution, and at the same time part of the powder will float away with the airflow, thereby causing the consumption of the powder.
[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a powder feeding mechanism for a concrete mixing station, comprising a main body, two connecting pieces are fixedly connected to the tops of both sides of the main body, and the other sides of the two connecting pieces connected to the main body are fixedly connected to cover plates;
[0007] Two driving mechanisms are installed on the front and rear sides of the main body, two supporting bodies are fixedly connected on the front and rear sides of the top of the main body, air blowing mechanisms are installed on the top slopes of the two cover plates, and two filters are fixedly connected to the surrounding surfaces of the main body.
[0008] The utility model is further configured as follows: the driving mechanism includes two fixing rings fixedly connected to one side of the front end of the main body, the inner walls of the two fixing rings are fixedly connected to a hydraulic cylinder, the top of the hydraulic cylinder is fixedly connected to a connecting column, the other end of the connecting column is rotatably connected to a limiting clamp, and the inner wall of the limiting clamp is slidably connected to the front end of one of the cover plates.
[0009] Through the above technical scheme, the cover plate can be repeatedly moved by using a driving mechanism, thereby reducing the amount of dust flying upward. Specifically, two connecting parts are used to movably connect the cover plate and the main body, and then the hydraulic cylinder is started. The hydraulic cylinder will extend upward to lift the connecting column. As the connecting column moves upward, and the connecting column and the limit clamp are rotatably connected, the limit clamp will move at the front end of the cover plate to gradually lift the cover plate. Conversely, after the powder is poured from the top of the main body, the cover plate will move downward as the hydraulic cylinder contracts, preventing the dust generated by the collision between the powder and the main body from floating upward into the air, thereby reducing the pollution of the dust to the air.
[0010] The utility model is further configured as follows: the blowing mechanism comprises a blower body fixedly connected to the top of one of the cover plates, an air inlet pipe is arranged at the front end of the blower body, an air outlet pipe is arranged at the bottom of the blower body, and the air outlet pipe runs through the cover plate.
[0011] Through the above technical scheme, by using the blowing mechanism to blow air downward, the generated dust can be blown downward with the air flow, thereby reducing the dispersion of the powder. Specifically, by starting the operation of the blower body, the blower body sucks air from the air inlet pipe and then discharges it from the air outlet pipe, thereby blowing away the dust. Then, excess gas will be discharged from multiple filters, excess dust will be absorbed by the filters, and gas will be discharged from the filter outlet, thereby saving the dispersion of powder and avoiding the pollution of dust to the air.
[0012] The utility model is further configured as follows: the tops of the two support bodies are connected to the slope support of the bottom of one of the cover plates.
[0013] Through the above technical solution, as dust enters, the two cover plates will cover the top of the main body. When the two cover plates are in contact, the multiple support bodies will form a certain supporting force on the two cover plates to prevent the cover plates from being damaged due to the deadweight of the blowing mechanism.
[0014] The utility model is further configured as follows: a plurality of filters are arranged at the middle position of the main body.
[0015] Through the above technical solution, the filter is set in the middle position of the main body. The purpose is that when the gas enters and exits the main body, due to the small diameter of the bottom of the main body, the gas cannot be relieved in time, and most of the gas is discharged from the filter.
[0016] The beneficial effects of the utility model are as follows:
[0017] 1. The utility model can prevent the dust generated by the collision from flying into the air through the cover plate by designing the driving mechanism and the blowing mechanism, and at the same time, the powder is blown into the device by the blower to prevent the dust generated by the collision from flying into the air with the airflow, thereby reducing the waste of dust and saving the cost of powder;
[0018] 2. The utility model designs a driving mechanism so that the cover plate can move repeatedly with the feeding. As the powder enters, the cover plate covers the main body to prevent dust from flying into the air and causing air pollution. At the same time, it drives the blowing mechanism to reach a certain position to avoid waste of powder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0025] See also Figure 1-Figure 4A powder feeding mechanism for a concrete mixing station includes a main body 1, two connecting pieces 2 are fixedly connected to the top of both sides of the main body 1, and the other sides of the two connecting pieces 2 connected to the main body 1 are fixedly connected to a cover plate 3, and two driving mechanisms 4 are installed on the front and rear sides of the main body 1. The driving mechanism 4 includes two fixing rings 401 fixedly connected to one side of the front end of the main body 1, and the inner walls of the two fixing rings 401 are fixedly connected to a hydraulic cylinder 402, and the top of the hydraulic cylinder 402 is fixedly connected to a connecting column 403, and the other end of the connecting column 403 is rotatably connected to a limited clamp 404, and the inner wall of the limited clamp 404 is slidably connected to the front end of one of the cover plates 3. By using the driving mechanism 4, the cover plate 3 can be reversed. The two connecting pieces 2 are used to flexibly connect the cover plate 3 and the main body 1, and then the hydraulic cylinder 402 is started, and the hydraulic cylinder 402 will extend upward to lift the connecting column 403. As the connecting column 403 moves upward, and the connecting column 403 is rotatably connected to the limiting clamp 404, the limiting clamp 404 will move at the front end of the cover plate 3 to gradually lift the cover plate 3. Conversely, after the powder is poured from the top of the main body 1, as the hydraulic cylinder 402 contracts, the cover plate 3 will move downward to prevent the dust generated by the collision between the powder and the main body 1 from floating upward into the air, thereby reducing the pollution of the dust to the air.
[0026] like Figure 4 As shown, two supporting bodies 5 are fixedly connected to the front and rear sides of the top of the main body 1, and the top slopes of the two cover plates 3 are both installed with blowing mechanisms 6. The blowing mechanism 6 includes a blower body 601 fixedly connected to the top of one of the cover plates 3, and an air inlet pipe 602 is arranged at the front end of the blower body 601, and an air outlet pipe 603 is arranged at the bottom of the blower body 601. The air outlet pipe 603 runs through the cover plate 3. Two filters 7 are fixedly connected to the surrounding surfaces of the main body 1. By using the blowing mechanism 6 to blow downward, the generated dust can be moved downward with the air flow, thereby reducing the dissipation of the powder. Specifically, by starting the blower body 601 to operate, the blower body 601 sucks air from the air inlet pipe 602 and then discharges it from the air outlet pipe 603, thereby blowing away the dust, and then the excess gas will be discharged from the multiple filters 7, the excess dust will be absorbed by the filter 7, and the gas will be discharged from the outlet of the filter 7, thereby saving the dissipation of the powder and avoiding the pollution of the air by the dust.
[0027] like Figure 1 and Figure 2As shown, the top of two support bodies 5 is connected to the bottom slope support of one of the cover plates 3. As dust enters, the two cover plates 3 will cover the top of the main body 1. When the two cover plates 3 are in contact, the multiple support bodies 5 will form a certain supporting force on the two cover plates 3 to prevent the cover plates 3 from being damaged due to the deadweight of the blowing mechanism 6. Multiple filters 7 are all arranged in the middle position of the main body 1. The filter 7 is arranged in the middle position of the main body 1 in order to, when the gas enters and exits the main body 1, due to the small diameter of the bottom of the main body 1, the gas cannot be relieved in time, and most of the gas is discharged from the filter 7.
[0028] When the utility model is in use, two connecting pieces 2 are used to movably connect the cover plate 3 and the main body 1. After the powder is poured in from the top of the main body 1, the hydraulic cylinder 402 is then started. The hydraulic cylinder 402 will shrink downward, thereby driving the connecting column 403 to move downward, and the connecting column 403 is rotatably connected to the limiting clamp 404, so that the limiting clamp 404 will move at the front end of the cover plate 3 until the two cover plates 3 are respectively in contact with the two support bodies 5. Conversely, as the hydraulic cylinder 402 extends, the cover plate 3 will move upward. After the cover plate 3 reaches the position, the blower body 601 is started to operate. The blower body 601 will suck air from the air inlet pipe 602 and then discharge it from the air outlet pipe 603, thereby blowing away the dust. Subsequently, excess gas will be discharged from multiple filters 7, and the excess dust will be absorbed by the filter 7, and the gas will be discharged from the outlet of the filter 7, thereby completing the entire powder feeding process.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
