Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology in concrete processing, and in particular to a feeding device for concrete production. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. The production and processing steps of concrete are: metering and batching, mixing, and transportation.

[0003] Current concrete production methods primarily involve using various types of mixing equipment to combine raw materials with other admixtures in specific proportions and then mixing to produce concrete. However, current material feeding is done manually, relying on estimated proportions, resulting in generally poor concrete quality. Furthermore, the feed inlets of current mixing equipment are located at the top, making manual feeding inconvenient. To address these issues, a new material feeding device for concrete production is proposed. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a feeding device for concrete production. The amount of material to be fed is determined by the quantitative hopper on the quantitative plate, eliminating the need for manual estimation each time material is fed. This reduces the problem of poor quality of processed concrete due to feeding errors. In addition, a spiral feeding component is added to complete the feeding operation, solving the problem of inconvenience of manual feeding operation due to the high position of the feed inlet of the mixing device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A feeding device for concrete production, characterized in that it includes a base plate, a fixed seat, a drive assembly, a turntable, a metering disc, and a screw feeding assembly. The fixed seat is mounted on the upper end of a support rod on the base plate. A turntable is positioned above the fixed seat and fixedly connected to a rotating shaft. The rotating shaft is connected to the drive assembly mounted on the base plate. A metering disc is positioned above the turntable. A discharge hole is provided on the fixed seat, and the screw feeding assembly is positioned below the discharge hole.

[0007] The metering disc is fixedly mounted on the turntable by screws, and a metering hopper is installed on the metering disc.

[0008] The lower end of the metering hopper extends into the through hole provided on the turntable, and the bottom end of the metering hopper contacts the surface of the fixed base.

[0009] A vibration motor is installed on the turntable. The vibration motor causes the metering disc fixed on the turntable to vibrate, so that when material is added into the metering hopper, the material is better filled into the metering hopper, and when the material in the metering hopper falls out of the discharge hole of the fixed seat, the material falls out more quickly and efficiently.

[0010] The drive assembly consists of a drive motor, a drive wheel, and a driven wheel. The output end of the drive motor is connected to the drive wheel, the drive wheel is engaged with the driven wheel, and the driven wheel is connected to the rotating shaft.

[0011] The driving wheel and the driven wheel are provided with protective covers, which are mounted on the base plate.

[0012] Furthermore, a bearing is provided at the connection between the rotating shaft and the fixed base.

[0013] The spiral feeding assembly consists of a material box, a feeding box, a feeding motor, a rotating shaft, and spiral blades. The hopper at the inlet on the top of the material box is located below the outlet on the fixed base. The inlet of the material box is connected to the inlet of the feeding box through a pipe. The feeding box is installed at an angle on the material box. The feeding motor is installed on the top of the feeding box. The output end of the feeding motor is connected to the rotating shaft. The rotating shaft is installed inside the feeding box through bearings. Spiral blades are provided on the rotating shaft.

[0014] Furthermore, a discharge port is provided on one side of the upper end of the feeding box.

[0015] The beneficial effects of this utility model are:

[0016] The feeding device designed in this utility model, after the metering hopper is filled, the drive motor in the drive assembly controls the turntable to rotate, thereby driving the metering disc to rotate. After the lower end of the metering hopper aligns with the discharge hole on the fixed base, the material in the metering hopper is fed into the screw feeding assembly. This allows the amount of material to be fed to be determined by the metering hopper on the metering disc, eliminating the need for manual estimation each time material is fed, and reducing the problem of poor quality of the processed concrete coating due to feeding errors.

[0017] In this utility model, the metering hopper used for measuring each addition of material is fixed on the metering disc, which is fixed to the turntable by screws. Therefore, when the amount of material added changes, the original metering disc can be removed and replaced with a metering disc with a metering hopper of the corresponding size to meet the needs of different processing applications and enhance practicality.

[0018] This utility model adds a spiral feeding component, which feeds a metered amount of material into the feeding box through a metering hopper each time. The feeding motor drives the spiral blades in the feeding box to rotate, sending the material from below to above, thus meeting the need to feed materials to devices with height. This solves the problem that the feed inlet of the current mixing device is too high, making manual feeding inconvenient. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1

[0027] As shown in the figure, a fixed seat 2 is installed at the upper end of the support rod 11 on the base plate 1. A turntable 3 is provided above the fixed seat 2. The turntable 3 is fixedly connected to the rotating shaft 31. A bearing 32 is provided at the connection between the rotating shaft 31 and the fixed seat 2. The rotating shaft 31 is connected to the driven wheel 73 in the drive assembly installed on the base plate 1. The driven wheel 73 and the driving wheel 72 are meshed. The driving wheel 72 is connected to the output end of the drive motor 71. A protective cover 9 is provided outside the driving wheel 72 and the driven wheel 73. The protective cover 9 is installed on the base plate 1.

[0028] like Figure 3 A metering disc 4 is installed above the turntable 2, and the metering disc 4 is fixedly mounted on the turntable 2 by screws 41. A metering hopper 5 is installed on the metering disc 4, and the lower end of the metering hopper 5 extends into the through hole 33 provided on the turntable 3. The bottom end of the metering hopper 5 is in contact with the surface of the fixed base 2. The fixed base 2 is provided with a discharge hole 21, and a material box 81 is provided below the discharge hole 21. The hopper 811 at the inlet of the material box 81 is located below the discharge hole 21 on the fixed base 2.

[0029] like Figure 4 The inlet of the material bin 81 is connected to the inlet of the feeding bin 82 via a pipe 812. The feeding bin 82 is installed at an angle on the material bin 81. A feeding motor 83 is installed on the top of the feeding bin 82. The output end of the feeding motor 83 is connected to a rotating shaft 84. The rotating shaft 84 is installed inside the feeding bin 82 via bearings, and a spiral blade 85 is provided on the rotating shaft 84. The feeding principle is based on the rotating spiral blade 85 pushing the material along the path of the feeding bin 82, thereby realizing the feeding of the material from the outlet 821 above.

[0030] Furthermore, a vibration motor 6 is installed on the turntable 3. The vibration motor 6 causes the turntable 3 to vibrate, which in turn causes the metering plate 4 to vibrate. This allows the material to better fill the metering hopper 5 when it is added to the metering hopper 5, and the material in the metering hopper 5 to fall out of the discharge hole 21 of the fixed seat 2 more quickly.

[0031] Example 2

[0032] When using this invention for feeding, firstly, select a metering disc 4 with a suitable metering hopper 5 according to the feeding requirements, and then fix the metering disc 4 to the turntable 3 with screws 51.

[0033] Material is fed into the metering hopper 5. After the metering hopper 5 is full of material, the drive motor 71 in the drive assembly is started. Through the meshing transmission of the drive wheel 72 and the driven wheel 73, the control shaft 31 drives the turntable 3 to rotate, thereby driving the metering disc 4 to rotate. When the metering disc 4 rotates to the position of the lower end port of the metering hopper 5 corresponding to the position of the discharge hole 21 on the fixed base 2, the material in the metering hopper 5 enters the hopper 811 of the screw feeding assembly. Thus, the amount of material fed can be determined by the metering hopper 5 on the metering disc 4, eliminating the need for manual estimation each time material is fed, and reducing the problem of poor quality of the processed concrete coating due to feeding errors.

[0034] It should be noted that when feeding material into the metering hopper 5, you can choose to feed it manually, or you can feed it into the metering hopper 5 by setting up a material cylinder above the metering hopper 5 and feeding it into the metering hopper 5 through the material cylinder. The operator needs to close the feeding operation of the material cylinder after the metering hopper 5 is full.

[0035] Each time the metering hopper 5 delivers the metered material to the hopper 811, it enters the feeding box 82 through the pipe 812. The feeding motor 83 drives the spiral blades 85 in the feeding box 82 to rotate, sending the material from below out through the discharge port 821 above. This fulfills the need to feed materials to devices with height, solving the problem that the current mixing device has a high inlet position, making manual feeding inconvenient.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
