Description

Technical Field

[0001] This utility model relates to the technical field of concrete production equipment, and in particular to a concrete batching device. Background Technology

[0002] Concrete is the most widely used man-made civil engineering material in the world, and is widely used in construction, infrastructure, roads, bridges, and many other fields. It possesses high strength, durability, and good adaptability, enabling it to withstand various external loads and environmental conditions, thus its widespread adoption globally. Existing concrete preparation processes typically include: pre-mixing aggregates and admixtures according to production needs; mixing the aggregates in a funnel; conveying the mixture to a mixer; mixing the admixtures in a funnel; adding the admixtures to the mixer after the aggregates have been delivered; dry mixing; adding water and additional additives; wet mixing; and finally, uniform mixing to form finished concrete, which is then unloaded and transported to the construction site by truck.

[0003] Commonly used concrete batching equipment is typically large in size and mainly used in large construction sites such as concrete mixing plants. However, this equipment is not suitable for some small construction sites because its size and design are more geared towards the needs of large-scale production. For small construction sites, existing batching equipment is generally manually fed, requiring operators to slowly feed the material as it approaches the set batching threshold. This not only significantly increases the labor intensity of workers but also makes it difficult to ensure the accuracy of the proportions due to reliance on manual judgment of the feeding amount. Since workers usually rely on visual observation to complete this operation, deviations are prone to occur, affecting the quality of the concrete and the accuracy of the proportions, thereby reducing overall work efficiency and operational safety. This manual operation method is not only time-consuming and inefficient but also increases the possibility of human error, further affecting the construction progress and production stability. Utility Model Content

[0004] The main purpose of this utility model is to provide a concrete batching device that can ensure the accuracy of the batching ratio, free up labor, improve the automation and practicality of the equipment, increase production efficiency, and ensure the stability of the loading and unloading process, thereby improving work efficiency and safety.

[0005] To achieve the above objectives, this utility model proposes a concrete batching device, comprising:

[0006] A batching shell, wherein an inlet pipe and an outlet pipe are fixedly connected to the upper side of the batching shell, and a discharge port is opened on the lower side of the batching shell;

[0007] A guide block, which is slidably connected in the batching housing;

[0008] A detection frame is rotatably connected inside the ingredient housing. A gravity sensor is fixedly connected inside the detection frame, and a material storage frame is slidably connected inside the detection frame, with the material storage frame abutting against the gravity sensor.

[0009] A linkage component is installed inside the batching housing and is used to flip the detection frame after detection and guide the material from the feed pipe to the discharge pipe.

[0010] In one possible implementation, the linkage component includes:

[0011] A drive motor is fixedly connected to the outer wall of the ingredient housing, and the drive shaft of the drive motor is fixedly connected to the detection frame.

[0012] A transmission plate is rotatably connected to the outer wall of the material dispensing housing on the side away from the drive motor and is fixedly connected to the detection frame. A linkage plate is hinged to the transmission plate, and the end of the linkage plate away from the transmission plate is slidably connected to the guide block.

[0013] In one possible implementation, a material-avoiding groove is provided on the inner wall of the material-avoiding shell facing the feed pipe. A buffer column is slidably connected to the inner wall of the material-avoiding groove, and a buffer block is fixedly connected to each buffer column. A buffer spring is sleeved on each buffer column, and the two ends of the buffer spring abut against the inner wall of the material-avoiding groove and the buffer block, respectively.

[0014] In one possible implementation, several buffer plates are fixedly connected inside the ingredient housing.

[0015] In one possible implementation, a dustproof plate is hinged to the ingredient housing to cover the discharge port.

[0016] In one possible implementation, the ingredient housing is provided with an exhaust hole, which is located on the inner wall of the ingredient housing on the side away from the discharge port.

[0017] This utility model's technical solution uses a gravity sensor to directly transmit data to the linkage component. When the linkage component receives the threshold set by the gravity sensor, it starts working. The drive motor directly drives the detection frame to flip, at which point the material filled in the detection frame is unloaded. Simultaneously, the cooperation between the transmission plate and the linkage plate causes the guide block to move downwards. When the detection frame is in a fully tilted state, the upper side of the guide block is flush with the inner wall of the inlet and outlet pipes. At this time, the material fed into the inlet pipe slides directly into the outlet pipe along the upper side of the guide block. Then, through the conveyor, the concrete material sliding out of the outlet pipe is transported back to the inlet pipe position, ensuring the circulation of the material. This eliminates the need for manual intervention during the concrete material feeding process, reducing labor intensity and ensuring the accuracy of the proportioning. In other words, through the design of the linkage component, users do not need to manually control the feed amount in real time when proportioning raw materials, which not only ensures the accuracy of the proportioning but also frees up labor, improves the automation level and practicality of the equipment, and increases production efficiency.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Example

[0029] Reference Figures 1 to 5 This utility model proposes a concrete batching device, comprising:

[0030] The mixing shell 11 has an inlet pipe 12 and an outlet pipe 13 fixedly connected to its upper side, and a discharge port 111 is opened on its lower side.

[0031] The guide block 14 is slidably connected in the batching housing 11;

[0032] The detection frame 15 is rotatably connected inside the ingredient housing 11. A gravity sensor 151 is fixedly connected inside the detection frame 15. A material storage frame 152 is slidably connected inside the detection frame 15, and the material storage frame 152 abuts against the gravity sensor 151.

[0033] The linkage component is installed inside the batching housing 11 and is used to flip the detection frame 15 after the detection is completed and guide the material from the feed pipe 12 to the discharge pipe 13.

[0034] As the concrete aggregate and materials pass through the feed pipe 12, they continuously fall into the storage box 152. Once the weight reaches the required proportion, the gravity sensor 151 sends a signal to the linkage component. When the linkage component receives the threshold set by the gravity sensor 151, it begins to operate. The drive motor 21 directly drives the detection box 15 to flip. At this time, the material stored in the detection box 15 is unloaded. Simultaneously, the cooperation between the transmission plate 22 and the linkage plate 23 causes the guide block 14 to move downward. When the detection box 15 is in a fully tilted state, the upper side of the guide block 14 contacts the inner wall of the feed pipe 12 and the discharge pipe 13. When the material is level, the material fed into the feed pipe 12 will slide directly into the discharge pipe 13 along the upper side of the guide block 14. Then, through the conveyor, the concrete material that slides out of the discharge pipe 13 is conveyed back to the position of the feed pipe 12, ensuring the circulation of the material. This eliminates the need for manual intervention during the feeding of concrete material, reducing labor intensity and ensuring the accuracy of the proportion. In other words, through the design of the linkage components, users do not need to manually control the feed amount in real time when proportioning raw materials. This ensures the accuracy of the proportion, frees up labor, improves the automation and practicality of the equipment, and increases production efficiency.

[0035] Reference Figures 1 to 5 The linkage components include:

[0036] The drive motor 21 is fixedly connected to the outer wall of the batching housing 11, and the drive shaft of the drive motor 21 is fixedly connected to the detection frame 15.

[0037] Transmission plate 22 is rotatably connected to the outer wall of the material housing 11 on the side away from the drive motor 21 and is fixedly connected to the detection frame 15. A linkage plate 23 is hinged on the transmission plate 22. The end of the linkage plate 23 away from the transmission plate 22 is slidably connected to the guide block 14.

[0038] When the linkage component receives the threshold set by the gravity sensor 151, it starts to work. The drive motor 21 directly drives the detection frame 15 to flip. At this time, the material filled in the detection frame 15 will be unloaded. At the same time, the cooperation between the transmission plate 22 and the linkage plate 23 will cause the guide block 14 to move downward. When the detection frame 15 is in a fully tilted state, the upper side of the guide block 14 is flush with the inner wall of the inlet pipe 12 and the outlet pipe 13. At this time, the material fed into the inlet pipe 12 will slide directly into the outlet pipe 13 along the upper side of the guide block 14. Then, through the conveyor, the concrete raw material that slides out of the outlet pipe 13 is conveyed back to the position of the inlet pipe 12, ensuring the circulation of raw materials. This eliminates the need for manual intervention during the feeding of concrete raw materials, reduces labor intensity, and ensures the accuracy of the proportioning.

[0039] Through the design of the linkage components, users do not need to manually control the feed amount in real time when mixing raw materials. This ensures the accuracy of the ratio, frees up labor, improves the automation level and practicality of the equipment, and increases production efficiency.

[0040] Reference Figure 3 and Figure 4 A material avoidance groove 24 is provided on the inner wall of the material avoidance shell 11 facing the feed pipe 12. A buffer column 25 is slidably connected to the inner wall of the material avoidance groove 24. A buffer block 26 is fixedly connected to each buffer column 25. A buffer spring 27 is sleeved on each buffer column 25. The two ends of the buffer spring 27 abut against the inner wall of the material avoidance groove 24 and the buffer block 26 respectively.

[0041] As the guide block 14 moves downwards in coordination with the linkage components, raw materials continue to be input into the feed pipe 12. These materials may interfere with the guide block 14, affecting its smooth downward movement. The buffer block 26 extends the distance the raw materials travel through the feed pipe 12 into the batching housing 11. The buffer block 26 acts as a buffer and guide; as the guide block 14 moves downwards, it exerts a squeezing effect on the buffer block 26, allowing the raw materials to flow smoothly through the buffer block 26 and reducing contact between the raw materials and the outer wall of the guide block 14. In this way, the buffer block 26 reduces the impact of the raw materials on the downward movement of the guide block 14, avoids interference that may occur when the raw materials directly contact the guide block, ensures the smooth downward movement of the guide block 14, improves the stability of equipment operation, and enhances the efficiency of the batching process.

[0042] Reference Figures 3 to 5 Several buffer plates 28 are fixedly connected inside the ingredient housing 11;

[0043] As concrete raw materials continuously fall into the storage frame 152 after passing through the feed pipe 12, they may cause wear and impact on the inner wall of the storage frame 152 and the inner wall of the batching shell 11. Several buffer plates 28 are used to effectively buffer and guide the concrete raw materials being fed. The function of the buffer plates 28 is to shorten the distance between the vertical fall of the raw materials and the bottom wall of the storage frame 152, thereby significantly reducing the impact force. At the same time, relatively small raw material particles can be fed more quickly, prompting a layer of fine sand to be quickly spread on the bottom wall. This layer of fine sand not only helps to reduce the impact of the remaining raw materials on the bottom wall of the storage frame 152, but also improves the stability and efficiency of the batching process and effectively extends the service life of the equipment.

[0044] Reference Figures 1 to 3 A dustproof plate 29 is hinged to the feed housing 11 to block the discharge port 111;

[0045] During the material feeding process, concrete aggregates and other materials enter the material storage box 152 through the feed pipe 12, which will raise a large amount of dust. In order to effectively prevent excessive dust from escaping, the dustproof plate 29 plays a blocking role, ensuring the cleanliness of the working environment outside the batching shell 11. When the material storage box 152 is tilted under the drive of the linkage component, the dustproof plate 29 will be pushed open to complete the material unloading operation. After unloading, the dustproof plate 29 will automatically reset under its own gravity and return to its original position to continue to play its function of blocking dust. The dustproof plate 29 can not only effectively control the spread of dust during the feeding process, but also quickly recover after unloading, ensuring that a good working environment and dust control are maintained for each feeding operation, improving the cleanliness of the working environment, and reducing the impact on the health of operators.

[0046] Reference Figure 2 and Figure 3 The batching shell 11 is provided with an exhaust hole 112, which is located on the inner wall of the batching shell 11 on the side away from the discharge port 111.

[0047] The outer side of the exhaust port 112 can be connected to an exhaust fan to suck away the dust and ash raised inside the mixing housing 11 during normal mixing, thereby reducing the amount of dust and ash adhering to the inner wall of the housing, effectively preventing the accumulation of dust and ash, and ensuring the long-term cleanliness and stable operation of the equipment. In addition, after the mixing operation is completed, the exhaust fan continues to run through the exhaust port 112, which can further clean the inside of the mixing housing 11, remove residual dust, improve the hygiene of the equipment and the cleanliness of the working environment, thereby reducing the frequency of maintenance and cleaning and extending the service life of the equipment.
