Description
Technical Field
[0001] The utility model relates to the technical field of aggregate feeding, in particular to a self-locking wind device for aggregate feeding of a concrete mixing plant. Background Art
[0002] Aggregate is a granular material that acts as a skeleton and filler in concrete and mortar. Aggregates can be divided into two categories: natural rock aggregates and artificially recycled aggregates. Among them, natural rock aggregates such as sand, pebbles, crushed stones, etc. are composed of natural rocks; while artificially recycled aggregates are recycled materials obtained by crushing concrete, clay bricks and industrial by-products such as slag, iron slag, powder slag, etc. Concrete mixing plant is a new type of concrete mixing equipment, usually including aggregate silo, cement silo, additive silo, conveying system, etc., which can realize the automation of concrete production and improve production efficiency, while reducing manual operations and reducing production costs.
[0003] In the production process of the pre-cooling concrete mixing plant, aggregates usually enter the aggregate silo of the mixing plant in the form of a rotary feeding hopper. Since the rotary feeding hopper needs to rotate to feed multiple aggregate silos, the rotary hopper and the aggregate connecting hoppers of each silo cannot be sealed, so there is a phenomenon of cold air overflowing from the pre-cooling silo and dust flying during the feeding process. Therefore, in order to solve the above problems, a self-locking wind device for aggregate feeding of a concrete mixing plant is proposed. Utility Model Content
[0004] The utility model aims to provide a self-locking wind device for aggregate feeding of a concrete mixing plant, so as to solve the problem in the prior art mentioned in the above background technology that since the rotary feeding hopper needs to rotate to feed multiple aggregate bins, the rotary hopper and the aggregate connecting hoppers of each bin cannot be sealed, so there is overflow of cold air from the pre-cooling bin and dust flying during the feeding process.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-locking wind device for aggregate feeding of a concrete mixing plant, comprising a pipe body, the pipe body comprising an extra-large stone and a large stone warehouse entry pipe, one side of the extra-large stone and the large stone warehouse entry pipe is provided with a medium-sized stone and a small stone warehouse entry pipe, the bottom ends of the extra-large stone and the large stone warehouse entry pipe and the medium-sized stone and the small stone warehouse entry pipe are both provided with a warehouse entry interface, and the lower surfaces of the extra-large stone and the large stone warehouse entry pipe and the medium-sized stone and the small stone warehouse entry pipe are both fixedly connected with a warehouse entry pipe bracket;
[0006] A wind locking mechanism is arranged on the inner side of the extra-large stone and large stone entry pipe, and the wind locking mechanism comprises a first axis plate seat, the first axis plate seat is fixedly connected to the inner wall of the extra-large stone and large stone entry pipe, the inner side of the first axis plate seat is movably connected with a first door axis, and the surface of the first door axis is fixedly connected with a first material blocking plate.
[0007] Preferably, the air-lock mechanism further includes a second shaft plate seat fixedly connected to the inner wall of the medium-sized and small-sized stone inlet pipe. A second door shaft is movably connected to the inner side of the second shaft plate seat, and a second baffle plate is fixedly connected to the surface of the second door shaft.
[0008] Preferably, the first baffle plate is movable inside the extra-large and large-sized stone inlet pipe through the first door shaft, and the second baffle plate is movable inside the medium-sized and small-sized stone inlet pipe through the second door shaft.
[0009] Preferably, an auxiliary mechanism is provided inside the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe. The auxiliary mechanism includes a support rod fixedly connected to the inner walls of the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe. A fixed box is fixedly connected to the surface of the support rod. A motor is fixedly installed inside the fixed box. A rotating rod is movably connected to the inner side of the fixed box. A connecting rod is fixedly connected to the surface of the rotating rod, and a connecting plate is fixedly connected to the surface of the connecting rod.
[0010] Preferably, the two groups of support rods and the fixed boxes are correspondingly connected, and the rotating rod is fixedly connected to the output end of the motor.
[0011] Preferably, the connecting rod is fixedly connected to the rotating rod in six groups, and three groups of connecting rods are correspondingly connected to the connecting plate.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. Through the arrangement of the first door shaft and the second door shaft, the first baffle plate and the second baffle plate can move inside the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe. Through the movement of the first baffle plate and the second baffle plate, the aggregate can enter the bin through the inlet interface. At the same time, when there is no need to enter the bin, the first baffle plate and the second baffle plate naturally droop, which can block the inlet interface, thereby avoiding the overflow of dust and cold air, and thus avoiding the phenomenon of dust flying during the feeding process.
[0014] 2. By the operation of the motor, the rotating rod can be driven to rotate. Then, the connecting rod and the connecting plate can rotate accordingly under the action of the rotating rod. The rotation of the connecting rod can disturb the entering aggregate, facilitating the stable falling of the aggregate, preventing the accumulation of the aggregate in the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe, and ensuring stable feeding into the bin. By the rotation of the connecting plate, the inner walls of the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe can be scraped, avoiding the adhesion of the aggregate on the inner walls of the extra-large and large-sized stone inlet pipe and the medium-sized and small-sized stone inlet pipe due to the humidity or adhesion of the aggregate, and reducing the accumulation of the aggregate.

On the lower surfaces of both the super-large stone and large stone feeding pipe 1 and the medium stone and small stone feeding pipe 11, there are fixedly connected feeding pipe brackets 13. Through the setting of the feeding pipe brackets 13, the super-large stone and large stone feeding pipe 1 and the medium stone and small stone feeding pipe 11 can be supported. Through the setting of the super-large stone and large stone feeding pipe 1 and the medium stone and small stone feeding pipe 11, aggregates of different diameters can enter, and then the aggregates can enter the bin under the action of the feeding interfaces 12;
[0025] Inside the super-large stone and large stone feeding pipe 1, there is an airtight mechanism. The airtight mechanism includes a first shaft plate seat 2, which is fixedly connected to the inner wall of the super-large stone and large stone feeding pipe 1. Inside the first shaft plate seat 2, there is a first door shaft 21 movably connected. On the surface of the first door shaft 21, there is fixedly connected a first baffle plate 22. Through the setting of the first door shaft 21 and the second door shaft 24, the first baffle plate 22 and the second baffle plate 25 can move inside the super-large stone and large stone feeding pipe 1 and the medium stone and small stone feeding pipe 11, and then the feeding of aggregates can be realized, and the feeding interfaces 12 can be blocked by the first baffle plate 22 and the second baffle plate 25, so as to prevent the leakage of cold air and dust.
[0026] Furthermore, the airtight mechanism also includes a second shaft plate seat 23, which is fixedly connected to the inner wall of the medium stone and small stone feeding pipe 11. Inside the second shaft plate seat 23, there is a second door shaft 24 movably connected. On the surface of the second door shaft 24, there is fixedly connected a second baffle plate 25. Through the movement of the second baffle plate 25, the feeding interface 12 on the medium stone and small stone feeding pipe 11 can be blocked.
[0027] Furthermore, the first baffle plate 22 moves inside the super-large stone and large stone feeding pipe 1 through the first door shaft 21, and the second baffle plate 25 moves inside the medium stone and small stone feeding pipe 11 through the second door shaft 24. Through the movement of the first baffle plate 22, the feeding interface 12 on the super-large stone and large stone feeding pipe 1 can be blocked.
[0028] Furthermore, auxiliary mechanisms are provided on the inner sides of the extra-large stone and large stone entry pipes 1 and the medium-sized stone and small stone entry pipes 11, and the auxiliary mechanisms include support rods 3, which are fixedly connected to the inner walls of the extra-large stone and large stone entry pipes 1 and the medium-sized stone and small stone entry pipes 11, and a fixing box 31 is fixedly connected to the surface of the support rods 3, a motor 32 is fixedly installed on the inner side of the fixing box 31, a rotating rod 33 is movably connected to the inner side of the fixing box 31, a connecting rod 34 is fixedly connected to the surface of the rotating rod 33, and a connecting plate 35 is fixedly connected to the surface of the connecting rod 34. By setting the support rods 3, the fixing box 31 can be supported, and by setting the fixing box 31, the motor 32 can be conveniently operated on the inner side of the fixing box 31 and drive the rotating rod 33 to rotate.
[0029] Furthermore, the two groups of support rods 3 and the fixed boxes 31 are connected correspondingly, and the rotating rod 33 and the output end of the motor 32 are fixedly connected. The operation of the motor 32 can drive the rotating rod 33 to rotate, and then the connecting rod 34 can stir the incoming aggregate during the rotation process, thereby preventing the aggregate from accumulating in the extra-large stone, large stone storage pipe 1 and the medium stone, small stone storage pipe 11.
[0030] Furthermore, the connecting rods 34 are fixedly connected to the rotating rods 33 in six groups, and three groups of connecting rods 34 are correspondingly connected to the connecting plates 35. Through the setting of the connecting plates 35, they can rotate under the action of the connecting rods 34, and can scrape the inner walls of the extra-large stone, large stone entry pipe 1 and the medium-sized stone, small stone entry pipe 11, so as to prevent the accumulation of aggregates on the inner walls of the extra-large stone, large stone entry pipe 1 and the medium-sized stone, small stone entry pipe 11 due to moisture.
[0031] Working principle: When in use, when aggregate enters the warehouse, the first baffle plate 22 and the second baffle plate 25 will move through the first door shaft 21 and the second door shaft 24 under the impact force of the aggregate, thereby realizing the opening of the first baffle plate 22 and the second baffle plate 25, so that the aggregate can enter the warehouse through the warehouse entry interface 12; when there is no need to enter the warehouse, the first baffle plate 22 and the second baffle plate 25 naturally hang down due to their own weight, sealing the warehouse entry interface 12, which can prevent the cold air and dust from overflowing;
[0032] The motor 32 is electrically connected to an external power source, and the staff starts the motor 32 by pressing a switch. The operation of the motor 32 drives the rotating rod 33 to rotate, and the connecting rod 34 and the connecting plate 35 will rotate accordingly under the action of the rotating rod 33, and then the connecting rod 34 can rotate under the action of the rotating rod 33 and stir the aggregate, which can prevent the accumulation of aggregate and facilitate the stable falling and entry of the aggregate into the warehouse. The rotation of the connecting plate 35 can rub against the inner walls of the extra-large stone, large stone warehouse entry pipe 1 and the medium-sized stone, small stone warehouse entry pipe 11, which can prevent the aggregate from sticking and accumulating on the inner walls of the extra-large stone, large stone warehouse entry pipe 1 and the medium-sized stone, small stone warehouse entry pipe 11.
