Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production equipment, and in particular relates to a dust prevention device for a silo of a concrete mixing station. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] Chinese patent application No. 202022025085.2 discloses a dust prevention device for a mixing silo of a concrete mixing station. The utility model can effectively prevent dust from flying through a silo cover and a dust prevention net. Controlling the opening and closing of the silo cover by controlling the extension and retraction of the hydraulic push rod can save manpower and has a higher degree of automation. The sealing gasket with a trapezoidal groove can effectively prevent dust from being blown out and has a better isolation effect. After finishing work, the dust accumulated on the dust prevention net can be caused to fall off by the vibration of the vibration motor, and then the dust prevention net can be cleaned together by spraying water with a rotating nozzle, which not only extends the service life and facilitates the next use, but also has a better dust prevention effect. At the same time, the mixing silo can be cleaned, killing two birds with one stone, saving the cleaning cost of the mixing silo, shortening the maintenance time and frequency of the mixing silo, and improving work efficiency and product production quality.

[0004] In the above patent, a dust-proof net is connected to the inside of the bin cover. The dust flying in the concrete mixing process adheres to the dust-proof net. When the bin cover and the inside of the mixing bin are sprayed with water, the dust adhered to the dust-proof net becomes wet and adheres to the dust-proof net. It is difficult to achieve the falling operation of the adhered dust only by the vibration of the vibration motor. In addition, the external water source is directly input into the bin cover and the inside of the mixing bin through the water inlet pipe. When the input water source is mixed with impurities, the impurities fall onto the dust-proof net, making it difficult to perform the falling operation. Utility Model Content

[0024] Specifically, the cleaning assembly 6 includes a protective member 61, a driving motor 62, a rotating rod 63, a brush 64, a water leakage hole 65 and a rotating rod 66. A protective member 61 is provided at one end of the spraying mechanism 5 and is located above the dustproof net 7. A driving motor 62 is provided inside the protective member 61. The output end of the driving motor 62 is connected to the rotating rod 63. The end of the rotating rod 63 away from the driving motor 62 is connected to the rotating rod 66. A plurality of water leakage holes 65 are provided on the rotating rod 66. A brush 64 is connected to the side of the rotating rod 66 away from the rotating rod 63.

[0025] By adopting the above technical solution, the driving motor 62 is used to drive the rotating rod 63 to rotate, the rotating rod 63 rotates to drive the rotating rod 66 to rotate, and the rotating rod 66 rotates to drive the brush 64 to rotate. During the rotation of the brush 64, the dust adhering to the dustproof net 7 can be cleaned. At the same time, under the action of the protective member 61, the water sprayed by the spraying mechanism 5 can be prevented from falling on the driving motor 62, thereby preventing the driving motor 62 from being damaged. After the water at the spraying point falls on the rotating rod 66, it drips into the mixing bin 4 through the leakage hole 65.

[0026] Specifically, the protective member 61 includes a protective tube 611, a clamping rod 612, a mounting ring 613 and a mounting groove 614. One end of the spraying mechanism 5 is located at the periphery of the driving motor 62 and is connected to the protective tube 611.

At the same time, under the action of the anti-slip ring, the operator can avoid slipping of the hand during the process of applying force to drive the mounting ring 613 to rotate, and can avoid friction between the operator's finger and the side wall of the rotating hole, thereby avoiding wear on the operator's finger.

[0030] When the present embodiment is used, the driving motor 62 is placed inside the protective tube 611, and the mounting ring 613 is then rotated and screwed into the mounting groove 614. When the mounting ring 613 completely enters the mounting groove 614, the abutting rod 612 abuts against the driving motor 62, and the driving motor 62 can be abutted and fixed. When the concrete mixing operation is required inside the concrete mixing station, the push-rotating mechanism 2 is used to drive the bin cover 1 to flip away from the mixing bin 4, and then the concrete is put into the mixing bin 4, and then the push-rotating mechanism 2 is used to drive the bin cover 1 to flip to the top of the mixing bin 4, and then the mixing The concrete inside the bin 4 is stirred and mixed. During the stirring and mixing operation, the dust-proof net 7 can prevent the flying dust from spreading to the surrounding environment. After the concrete stirring and mixing is completed, when the dust-proof net 7 needs to be cleaned, the dust-proof net 7 is rinsed by the spraying mechanism 5, and the driving motor 62 is started at the same time. The driving motor 62 drives the rotating rod 63 to rotate, and the rotating rod 63 drives the rotating rod 66 to rotate. The rotating rod 66 drives the brush 64 to rotate. During the rotation of the brush 64, the dust adhering to the dust-proof net 7 can be cleaned to ensure the cleaning effect of the dust-proof net 7.
