Description

Technical Field

[0001] The utility model relates to the field of concrete processing equipment, in particular to a dustproof closed concrete mixing device. Background Art

[0002] Concrete is a material made of cement, aggregates (such as sand, gravel), water and other additives. It is one of the most commonly used materials in construction projects and is used to make structures such as foundations, floors, walls, columns, beams, etc. The production process of concrete is usually to mix cement, aggregates and water in a mixing device in a certain proportion to form a uniform slurry. Adding an appropriate amount of water to concrete can make the concrete flow well and easy to construct.

[0003] However, in the process of using the stirring device in the prior art, when the cement material is added, dust will be generated under the action of airflow, which will affect the working environment on the one hand, and on the other hand, part of the cement will be attached to the inner wall of the top of the stirring device along with the dust, making it difficult to directly stir and mix, thus affecting the stirring efficiency and making it difficult to achieve dust reduction during the stirring process;

[0004] In addition, during the mixing process of concrete, cement and other materials need to be added into the mixing device according to demand. Since the materials in the mixing device have a certain humidity, the subsequent addition of dry materials is prone to agglomeration if directly poured, resulting in uneven mixing, thereby prolonging the mixing time and making it difficult to achieve uniform feeding of materials.

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model uses gear 1 and gear 2 in coordination. In actual use, the basic material is first transported to the tank body through the feed pipe, and then the subsequent material is poured from the feed hopper into the shell body 2. After adding water, the motor is started, and the motor is used to drive the stirring rod to stir the material. While the stirring rod rotates, gear 1 drives gear 2 to rotate synchronously, and then drives the turntable to rotate. At this time, under the action of the connecting rod, the moving rod drives the piston to move in the sleeve. When the piston moves toward the connecting rod, a vacuum is generated inside the sleeve. At this time, the one-way valve 1 opens and the one-way valve 2 closes, and water enters the sleeve from the shell body 2. When the piston moves away from the connecting rod, the one-way valve 1 closes and the one-way valve 2 opens.

[0015] (2) The utility model uses the gear 1 and the gear 3 in coordination. When the gear 1 drives the gear 2 to rotate, the gear 3 rotates synchronously, thereby driving the half gear to rotate. The half gear drives the rack to move. At this time, the material discharge port is opened, and the material falls from the shell 2. After the toothed part of the half gear is separated from the rack, the spring drives the moving plate to reset and close the material discharge port. With the continuous rotation of the gear 1, the material is fed evenly, the occurrence of caking is avoided, and the mixing efficiency is improved.

[0016] At the same time, when the material falls from the second shell, the liquid sprayed from the spray head reduces the dust generated during the feeding, and also preliminarily wets the material, further avoiding the phenomenon of agglomeration caused by direct mixing with the material in the tank.

[0017] In summary, the utility model realizes uniform feeding of materials while achieving dust reduction. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 2:

[0033] This embodiment is used to solve the problem that during the mixing process of concrete, cement and other materials need to be added into the mixing device according to demand. Since the materials in the mixing device have a certain humidity, the subsequent addition of dry materials is prone to agglomeration if directly poured, resulting in uneven mixing, thereby prolonging the mixing time and making it difficult to achieve uniform feeding of the materials.

[0034] See also Figure 6 As shown, the utility model also includes a gear three 403, which is movably connected to the inner wall of the tank body 1 and is located on one side of the gear one 401, and the gear three 403 is meshed with the gear one 401.

[0037] In combination with Example 1 and Example 2, by using the motor 102 and the stirring rod 103 in coordination, while the motor 102 drives the stirring rod 103 to rotate, it also drives the rotating rod 1 404 and the rotating rod 2 416 to rotate synchronously, thereby driving the moving rod 409 to move, and utilizing the shell 2 3 and the sleeve 408 to spray the material, while driving the half gear 417 to rotate, and utilizing the rack 304 and the moving plate 303 to achieve uniform feeding of the material.

[0038] The working process and principle of the utility model are as follows:

[0039] First, the basic material is transported to the tank body 1 through the feed pipe 101, and then the subsequent material is poured from the feed hopper 301 into the shell body 2 3. After adding water, the motor 102 is started, and the motor 102 is used to drive the stirring rod 103 to stir the material. While the stirring rod 103 rotates, the gear 1 401 drives the gear 2 402 to rotate synchronously, and then drives the turntable 405 to rotate. At this time, under the action of the connecting rod 407, the moving rod 409 drives the piston 410 to move in the sleeve 408. When the piston 410 moves to the connecting rod 407, the piston 410 moves to the connecting rod 407. When the connecting rod 407 moves in the direction of the connecting rod 407, a vacuum is generated inside the sleeve 408. At this time, the one-way valve 1 412 is opened, the one-way valve 2 415 is closed, and water enters the sleeve 408 from the shell 2 3. When the piston 410 moves away from the connecting rod 407, the one-way valve 1 412 is closed, and the one-way valve 2 415 is opened. Under the squeezing action of the piston 410, the water is sprayed out from the spray head 414 through the water outlet 413. On the one hand, the dust generated by the added materials is reduced, and on the other hand, adding water in batches effectively improves the material mixing effect;

[0040] Furthermore, in the process that the gear 1 401 drives the gear 2 402 to rotate, the gear 3 403 rotates synchronously, thereby driving the half gear 417 to rotate, and the half gear 417 drives the rack 304 to move. At this time, the discharge port 302 is opened, and the material falls from the shell 2 3. After the toothed part of the half gear 417 is separated from the rack 304, under the action of the spring, the movable plate 303 is driven to reset to close the discharge port 302. With the continuous rotation of the gear 1 401, the material is fed evenly, the occurrence of caking is avoided, and the mixing efficiency is improved.

[0041] Furthermore, when the material falls from the shell 2 3, the liquid sprayed from the spray head 414 not only reduces the dust generated when adding the material, but also preliminarily wets the material, further preventing it from directly mixing with the material in the tank 1 to produce agglomeration;

[0042] The utility model realizes uniform feeding of materials while achieving dust reduction.
