Description

Technical Field

[0001] The utility model relates to the technical field of concrete mortar wrapped stone production, in particular to an aggregate pre-feeding hopper that can be used in the production process of concrete mortar wrapped stone. Background Technique

[0002] Concrete mortar wrapped stone, also known as mortar wrapped stone or stone dry hanging, is a building decoration material. It is usually a construction method in which natural stone, ceramic tiles or other facing materials are bonded to the base wall through cement mortar. Aggregates are granular materials that play a skeletal and filling role in concrete and mortar, and are divided into two types: fine aggregates and coarse aggregates. The particle diameter of fine aggregates is between 0.16 and 5 mm, and commonly used ones include natural sand (such as river sand, sea sand and valley sand) and artificial sand (ground from hard rock). The particle diameter of coarse aggregates is greater than 5 mm, and commonly used ones include crushed stone and pebbles. Aggregates play a skeletal and supporting role in concrete and are very important raw materials in construction. When producing concrete mortar wrapped stone, in order to add aggregates, a pre-feeding hopper is usually used. The pre-feeding hopper is a device that automatically and accurately adds aggregates during the production process. By using the pre-feeding hopper, aggregates can be accurately added, which can reduce the time and error of manual feeding, thereby improving the production efficiency of concrete. At the same time, it can reduce the handling and feeding work of workers on aggregates, reduce labor intensity and improve work safety.

[0003] In the prior art, during the production of concrete mortar wrapped stone, when adding aggregates, sand and stones are usually processed and added into the pre-feeding hopper and then centrally added to the mixer. Since sand and stones cannot be well pre-stored and separately added during the addition process, unevenness is likely to occur during the mixing process, which is not conducive to the more uniform distribution of cement in the concrete, and thus the mixing effect and production quality cannot be well guaranteed. Therefore, in order to solve the above problems, an aggregate pre-feeding hopper that can be used in the production process of concrete mortar wrapped stone is proposed. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0022] The support 21, vibration motor 24, rotary vane level gauge 25, and first motor 34 used in this application are products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here.

[0023] An aggregate pre-feeding hopper applicable to the concrete mortar stone wrapping production process includes a hopper body. The hopper body includes a platform 1. A sand pre-storage hopper 11 is arranged on the surface of the platform 1. The top of the sand pre-storage hopper 11 is fixedly connected to a stone pre-storage hopper 12. The top of the stone pre-storage hopper 12 is fixedly connected to a protective cover 13. An inspection door 14 is arranged on the surface of the protective cover 13. A dust collector 15 is arranged at the top of the protective cover 13. Through the settings of the sand pre-storage hopper 11 and the stone pre-storage hopper 12, stones and sand can be fed into the mixer in batches;

[0024] A feeding mechanism is arranged on the surface of the sand pre-storage hopper 11. The feeding mechanism includes a residual material induction sensor 2. The residual material induction sensor 2 is fixedly installed on the surface of the platform 1. A support 21 is fixedly connected to the surface of the sand pre-storage hopper 11. A stone storage hopper arc door 22 is arranged at the bottom of the stone pre-storage hopper 12. A flat flap door 23 is arranged at the bottom of the sand pre-storage hopper 11. A vibration motor 24 is fixedly installed on the surface of the sand pre-storage hopper 11. A rotary vane level gauge 25 is fixedly installed on the surface of the stone pre-storage hopper 12. By opening and closing the stone storage hopper arc door 22 and the flat flap door 23, sand and stones can be added to the sand pre-storage hopper 11 and the stone pre-storage hopper 12, and then the sand and stones can be fed into the mixer in batches.

[0025] Furthermore, the inspection doors 14 are arranged in two groups. One group of inspection doors 14 is arranged on the surface of the protective cover 13, and the other group of inspection doors 14 is arranged on the surface of the stone pre-storage hopper 12. Through the settings of the two groups of inspection doors 14, the inside of the stone pre-storage hopper 12, as well as the inside of the stone storage hopper arc door 22 and the sand pre-storage hopper 11, can be used for maintenance.

[0026] Furthermore, the stone pre-storage hopper 12 has a double-layer structure inside and outside. The outer layer of the stone pre-storage hopper 12 is fixedly connected to the sand pre-storage hopper 11, and the outer layer is arranged inside the sand pre-storage hopper 11 and connected to the shield 13. One end of the support 21 away from the sand pre-storage hopper 11 is fixedly connected to the residual material induction sensor 2. Through the setting of the residual material induction sensor 2, it can cooperate with the control software, and then be able to read the weights of the aggregate in the sand pre-storage hopper 11 and the stone pre-storage hopper 12, so that the stones and sand can be accurately added.

[0027] Furthermore, a discharging mechanism is arranged inside the sand pre-storage hopper 11. The discharging mechanism includes a baffle 3. The baffle 3 is fixedly connected to the inner wall of the sand pre-storage hopper 11. A fixed block 31 is fixedly connected to the lower surface of the baffle 3. A first rotating rod 32 is movably connected inside the sand pre-storage hopper 11. A first conical gear 33 is fixedly connected to the surface of the first rotating rod 32. A first motor 34 is fixedly installed on the surface of the sand pre-storage hopper 11. A second rotating rod 35 is movably connected inside the fixed block 31. A second conical gear 36 is fixedly connected to the top end of the second rotating rod 35. A connecting rod 37 is fixedly connected to the surface of the second rotating rod 35. A connecting plate 38 is fixedly connected to the surface of the connecting rod 37. Through the setting of the baffle 3, the first rotating rod 32, the first conical gear 33, the second rotating rod 35 and the second conical gear 36 can be shielded, the collision of stones can be avoided, and thus a protective effect can be achieved and the loss can be reduced.

[0028] Furthermore, one end of the first rotating rod 32 away from the first conical gear 33 is fixedly connected to the output end of the first motor 34. The first rotating rod 32, the first conical gear 33, the second rotating rod 35 and the second conical gear 36 are all movable inside the fixed block 31. Through the setting of the first conical gear 33 and the second conical gear 36, when the first conical gear 33 rotates under the action of the first rotating rod 32, the second conical gear 36 can be driven, and then the second rotating rod 35 can drive the connecting rod 37 and the connecting plate 38 to rotate accordingly.

[0029] Furthermore, one end of the connecting rod 37 is fixedly connected to the second rotating rod 35, and the other end of the connecting rod 37 is fixedly connected to the connecting plate 38. Through the setting of the connecting rod 37, when the second rotating rod 35 rotates, the connecting rod 37 can drive the connecting plate 38 to rotate accordingly. Then the rotation of the connecting plate 38 can prevent the sand from adhering to the inner wall of the sand pre-storage hopper 11, resulting in accumulation, so that the sand can better enter the mixer and waste can be reduced.

[0030] Working principle: When in use, the residual material induction sensor 2 is set to be able to read the weight of the aggregate in the pre-feeding hopper. When pre-storing materials, first open the stone storage hopper arc door 22. At this time, the flat flap door 23 at the bottom of the sand pre-storage hopper 11 is closed. Put the required weight of sand into the sand pre-storage hopper 11, and then close the stone storage hopper arc door 22. At this time, the flat flap door 23 at the bottom of the sand pre-storage hopper 11 still remains closed. Put the required weight of stones into the stone pre-storage hopper 12. When discharging materials to the mixing main machine, first open the flat flap door 23 at the bottom of the sand pre-storage hopper 11. At this time, the stone storage hopper arc door 22 is still in the closed state. Put the sand in, add water, cement, etc. and stir evenly. Then open the stone storage hopper arc door 22 and keep the flat flap door 23 at the bottom of the sand pre-storage hopper 11 in the open state, and add stones.

[0031] The first motor 34 is electrically connected by an external power supply. The staff starts the first motor 34 by pressing the switch. The operation of the first motor 34 drives the first rotating rod 32 to rotate. The first conical gear 33 will rotate under the action of the first rotating rod 32. Furthermore, the second conical gear 36 can rotate under the action of the first conical gear 33 and drive the second rotating rod 35 to rotate accordingly. Thus, it is realized that the connecting rod 37 drives the connecting plate 38 to rotate under the action of the second rotating rod 35. The rotation of the connecting plate 38 can scrape the inner wall of the sand pre-storage hopper 11, which can prevent sand from adhering to and accumulating on the inner wall of the sand pre-storage hopper 11, so that the remaining sand can better enter the mixer.

[0032] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the present invention according to the instructions in the attached drawings and the above content. However, any slight changes, modifications, and equivalent changes made by those skilled in this professional field within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
