Description

Technical Field

[0001] This utility model relates to the technical field of concrete product manufacturing equipment, and in particular to a double-hopper concrete brick forming machine. Background Technology

[0002] A concrete brick forming machine is a machine that uses materials such as fly ash, river sand, gravel, stone powder, fly ash, waste ceramsite slag, and smelting slag, with a small amount of cement added, to produce new types of wall bricks and paving bricks.

[0003] Most existing concrete brick forming machines have a single hopper, producing concrete bricks of a single color, which cannot be used to produce concrete bricks with two different colors. In addition, most existing concrete brick forming machines include a feeding trolley and a base located under the feeding trolley. The base is fixedly connected to the frame of the concrete brick forming machine and cannot be disassembled, making it difficult to clean up the concrete material that falls on the base. Utility Model Content

[0004] The purpose of this invention is to provide a double-hopper concrete brick forming machine. It employs a double-hopper structure, with the first hopper preparing raw materials of one color and the second hopper preparing raw materials of another color. These materials are then fed into the forming chamber via feeding trolleys for pressing and forming, producing concrete bricks with two distinct colors. A feeding base plate and a drive assembly for relative displacement of the feeding base plate on the base are installed between the hydraulic feeding trolley and the base. After feeding is completed, the drive assembly moves the feeding base plate, pushing it and the hydraulic feeding trolley on it out together. This provides sufficient cleaning space for easy cleaning of the feeding base plate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a double-hopper concrete brick forming machine includes a base, a forming chamber is provided above the base, a pressing component is provided inside the forming chamber, a forming component is provided outside the forming chamber, the forming component includes a feeding mechanism and a hydraulic feeding trolley, the forming components are symmetrically arranged on the left and right sides of the forming chamber, a feeding mechanism is provided on the base, a hopper is provided above the feeding mechanism, the feeding mechanism includes a feeding base plate and a driving component that drives the feeding base plate to move relative to each other on the base, and the hydraulic feeding trolley moves left and right on the surface of the feeding base plate.

[0006] By adopting the above technical solution and using a dual-hopper design, a layered material distribution process can be achieved. For example, one hopper can be loaded with gray concrete and the other hopper can be loaded with colored concrete. In the production of concrete bricks, functionality and decoration can be combined, thereby increasing the added value of the product and expanding market competitiveness.

[0007] Furthermore, this solution includes a feeding base plate that can be moved outward relative to the base between the base and the hydraulic feeding vehicle. This facilitates comprehensive cleaning of the base plate by the operator, preventing the drive components from jamming or the guide rails from being worn after the concrete has hardened. This reduces downtime caused by mechanical failures, and the feeding base plate, as an independent module, can be quickly disassembled and replaced.

[0008] The present invention is further configured such that: the driving assembly includes an active driving assembly and a driven driving assembly, the active driving assembly is located above the base, and the driven driving assembly is located below the feeding base plate. The active driving assembly includes a motor and a gear fixedly located at the end of the output shaft of the motor. The driven driving assembly includes a rack fixedly located at the lower part of the feeding base plate and meshing with the gear.

[0009] By adopting the above technical solution, when the electric motor drives the gear to rotate, the rotational motion is converted into linear motion through the meshing of the gear and rack, driving the feeding base plate to move along the base guide rail to the side away from the molding chamber.

[0010] A further feature of this invention is that a steel guide rail fixed on the base is provided between the feeding base plate and the base, and a slider that cooperates with the steel guide rail is fixedly provided at the lower part of the feeding base plate.

[0011] By adopting the above technical solution, a guide rail is set on the base. Compared with the direct sliding contact between the feeding base plate and the base, the use of steel guide rail greatly reduces the contact area, reduces the wear caused by sliding friction on the machinery, and also reduces the driving energy consumption. Furthermore, the steel guide rail cooperates with the slider to ensure that the feeding base plate moves along a uniquely determined path.

[0012] A further feature of this invention is that the material of the feeding base plate is one of high-strength steel, cast iron, and stainless steel.

[0013] By adopting the above technical solutions, the feeding base plate has high strength and wear resistance, and is stable and reliable.

[0014] A further feature of this invention is that the feeding base plate is arranged along the length of the base.

[0015] By adopting the above technical solution, the longitudinal space of the base can be fully utilized by moving along the length direction, so that the feeding base plate can be completely moved out of the bottom of the molding chamber, which makes it convenient for operators to clean the feeding base plate from all directions and avoid cleaning dead corners caused by space limitations.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through its dual-hopper design, enables a layered material distribution process. For example, one hopper can be loaded with gray concrete, while the other hopper can be loaded with colored concrete. In the production of concrete bricks, functionality and decoration can be combined, thereby increasing the added value of the product and expanding market competitiveness.

[0018] 2. This utility model has a feeding base plate that can be moved outward relative to the base between the base and the hydraulic feeding trolley, which makes it convenient for operators to clean the base plate from all angles. This can prevent the drive components from getting stuck or the guide rails from being worn after the concrete has hardened, reduce downtime caused by mechanical failure, and the feeding base plate can be quickly disassembled and replaced as an independent module.

[0019] 3. A steel guide rail fixed to the base is provided between the feeding base plate and the base. A slider that cooperates with the steel guide rail is fixedly provided on the lower part of the feeding base plate. The use of the steel guide rail greatly reduces the contact area compared with the direct sliding contact between the feeding base plate and the base, which reduces the wear and tear caused by sliding friction on the machine and also reduces the driving energy consumption. Furthermore, the cooperation between the steel guide rail and the slider ensures that the feeding base plate moves along a unique and determined path. Attached Figure Description

[0026] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this utility model provides a double-hopper concrete brick forming machine, including a base 1, a forming chamber 3 above the base 1, a pressing component 4 inside the forming chamber 3, and a forming component 5 outside the forming chamber 3. The forming component 5 includes a feeding mechanism 51 and a hydraulic feeding cart 2. The forming components 5 are symmetrically arranged on the left and right sides of the forming chamber 3. A feeding mechanism 52 is provided on the base 1. A hopper 511 is provided above the feeding mechanism 51. The feeding mechanism 52 includes a feeding base plate 521 and a driving component 6 that drives the feeding base plate 521 to move relative to the base 1. The hydraulic feeding cart 2 moves left and right on the surface of the feeding base plate 521.

[0028] It is worth noting that the base 1, hydraulic feeding trolley 2, molding chamber 3, pressing assembly 4, and molding assembly 5 are all existing components on existing concrete brick molding machines, and their functions and specific structures are relatively mature, so they will not be described in detail here.

[0029] Furthermore, the drive assembly 6 includes an active drive assembly 61 and a driven drive assembly 62. The active drive assembly 61 is located above the base 1, and the driven drive assembly 62 is located below the feeding base plate 521.

[0030] Furthermore, the active drive assembly 61 includes a motor 611 and a gear 612 fixedly disposed at the end of the output shaft of the motor 611, and the driven drive assembly 62 includes a rack 621 fixedly disposed at the lower part of the feeding base plate 521 and meshing with the gear 612.

[0031] Furthermore, a steel guide rail 7 fixed on the base 1 is provided between the feeding base plate 521 and the base 1, and a slider 8 that cooperates with the steel guide rail 7 is fixedly provided at the lower part of the feeding base plate 521.

[0032] Furthermore, the material of the feeding base plate 521 is one of high-strength steel, cast iron, and stainless steel.

[0033] Furthermore, the feeding base plate 521 is set along the length direction of the base 1.

[0034] In practice, the feeding mechanism 51 mainly consists of a hopper 511, a storage bin, and a feeding control device. When the double hopper 511 is designed, the two hoppers 511 are loaded with concrete of different colors, such as gray concrete on one side and colored concrete on the other. The mixed concrete raw materials are poured into the hopper 511 by mechanical or manual means. The concrete raw materials enter the storage bin from the hopper 511. The bin is equipped with a mixing device to prevent the concrete raw materials from segregating during the storage process. An adjustable gate is provided on the side of the storage bin. The gate opening is set through the control panel to control the feeding speed and flow rate of the concrete raw materials.

[0035] Concrete falling from the storage hopper enters the hydraulic feeding truck 2. The bottom of the hydraulic feeding truck 2 is equipped with a weighing sensor. When the weighing sensor detects that the amount of material falling into the hydraulic feeding truck 2 has reached the set amount, the gate automatically closes, stopping the feeding. After completing the loading task, the hydraulic feeding truck 2 moves to the molding chamber 3. The bottom of the molding chamber 3 is equipped with a brick-shaped mold. Inside the hydraulic feeding truck 2, there is a transverse pusher plate that pushes the concrete material into the molding chamber 3. The concrete material falls into the brick-shaped mold. A vibration device can be installed on the outside of the brick-shaped mold, preferably a vibration motor, which can produce a continuous and stable vibration effect, promoting the rapid and uniform filling of all corners of the mold by the concrete material, resulting in uniform compaction.

[0036] This utility model features a double-hopper 511 structure with symmetrical sides. The hydraulic feeder 2 on the left side of the forming chamber 3 delivers red concrete raw material into the brick mold, where it is vibrated evenly to form the lower layer of the two-color brick. Subsequently, another hydraulic feeder 2 on the right side of the forming chamber 3 delivers gray concrete raw material into the brick mold, covering the upper layer of red concrete raw material. The material is then pressed down by the pressing component 4 to form a two-layered concrete brick. This double-layered two-color brick combines functionality and decoration, enhancing product added value and expanding market competitiveness.

[0037] The pressing assembly 4 is primarily responsible for compacting the concrete material within the brick mold, ensuring the bricks achieve the specified strength and dimensional accuracy. The pressing assembly 4's power system is hydraulically driven, providing stable pressure through an oil pump station. The shape of the pressing head's bottom matches the brick mold; for example, for standard rectangular bricks, the mold cavity is a regular cuboid, and the bottom of the pressing head is designed as a flat plane. For bricks with patterns or raised / recessed structures, the bottom of the pressing head replicates the reverse contour of the mold. Guide columns are installed on both sides of the pressing head to ensure vertical pressing accuracy. The control panel allows setting the working stroke and pressing speed of the pressing head. Sensors monitor the position in real time to ensure the pressing head moves precisely within the preset stroke, preventing damage to the bricks due to overtravel or excessive speed.

[0038] Once the two-color bricks are formed, workers can enter the forming chamber 3 to remove the bricks, or workers can use existing transfer equipment, such as forklifts or conveyor equipment, to move the bricks after they have been formed. Since the above methods are all existing conventional processing methods, they will not be described in detail here.

[0039] The feeding base plate 521 does not move during the operation of the brick machine. The self-locking function of the motor 611 locks the drive gear 612. After the double-layer double-color concrete bricks are processed, the motor 611 located above the base 1 is turned on. The motor 611 drives the gear 612 to rotate. The rotational motion is converted into linear motion through the meshing of the gear 612 and the rack 621, which drives the feeding base plate 521 to move along the guide rail of the base 1 to the side away from the forming chamber 3. This makes it easier for the operator to clean the base plate from all angles. It can prevent the drive component 6 from getting stuck or the guide rail from being worn after the concrete has hardened, reduce downtime caused by mechanical failure, and the feeding base plate 521 can be quickly disassembled and replaced as an independent module.

[0040] A steel guide rail 7 is installed on the base 1. Compared with the direct sliding contact between the feeding base plate 521 and the base 1, the use of the steel guide rail 7 greatly reduces the contact area, reduces the wear caused by sliding friction on the machinery, and also reduces the driving energy consumption. Furthermore, the steel guide rail 7 cooperates with the slider 8 to ensure that the feeding base plate 521 moves along a uniquely determined path.

[0041] The material of the feeding base plate 521 is one of high-strength steel, cast iron and stainless steel, which gives the feeding base plate 521 high strength and wear resistance, stability and reliability. In addition, the feeding base plate 521 is set along the length of the base 1, which can make full use of the longitudinal space of the base 1, so that the feeding base plate 521 can be completely moved out of the bottom of the molding chamber 3, which makes it convenient for operators to clean the feeding base plate 521 from all directions and avoids cleaning dead corners caused by space constraints.
