Description

Technical Field

[0001] This utility model relates to the field of cement processing technology, specifically a concrete production equipment. Background Technology

[0002] Concrete is a commonly used building material, made by mixing cement, sand, aggregates (such as gravel or crushed stone), and a suitable amount of water in a specific ratio. It is characterized by its strength and durability and is widely used in construction, infrastructure, roads, bridges, and other engineering projects. The main component of concrete is cement. Cement is a powdery substance that reacts chemically with water to form hydration hardening products, allowing concrete to take shape and gradually become stronger. Sand and aggregates form the skeleton of concrete, providing strength and stability, while water is used to fully wet the concrete components and promote the hydration reaction. The mix proportions of concrete are usually determined based on specific project needs and design requirements. By adjusting the ratio of cement, sand, aggregates, and water, the strength, fluidity, and durability of the concrete can be controlled.

[0003] Patent publication number "CN221066731U" discloses "a concrete production device," including a mixing bin. The top of the mixing bin is equipped with a uniform feeding component, and the middle of the mixing bin is equipped with a stirring mixing component for mixing concrete raw materials. The surface of the mixing bin is also equipped with transverse and longitudinal mixing components for accelerating mixing. A discharge pipe is fixedly inserted into the center of the bottom surface of the mixing bin, and support legs are provided at each of the four corners of the bottom surface. The uniform feeding component includes a feeding hopper, the bottom of which is fixedly connected with a feeding pipe, which is also fixedly connected to the top of the mixing bin. The number of feeding pipes is at least four. In use, this device facilitates the mixing of concrete raw materials at multiple stages and locations, resulting in more uniform mixing of concrete raw materials compared to existing technologies, effectively improving the mixing rate and thus increasing concrete production efficiency.

[0004] The feeding hoppers in the aforementioned patents mostly have smooth inner walls and lack diversion or vibration auxiliary components. When a large amount of raw material is concentrated in the feeding hopper, the raw material particles support each other to form a stable arched structure, preventing the raw material below from falling smoothly. This causes a sharp drop in the raw material flow rate, further exacerbating the risk of accumulation, thus resulting in slow feeding efficiency.

[0005] Therefore, this utility model provides a concrete production equipment to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a concrete production equipment that solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A concrete production equipment includes a mixing chamber. A feeding mechanism is fixedly connected to the upper surface of the mixing chamber, and a mixing mechanism is fixedly connected to the side surface of the mixing chamber. The feeding mechanism includes a mounting plate fixedly connected to the upper surface of the mixing chamber. Multiple sets of springs are fixedly connected to the upper surface of the mounting plate. A feeding hopper is fixedly connected to the upper end of each spring. A vibrating motor is fixedly connected to the lower surface of the feeding hopper, and a conveying pipe is connected to the side surface of the feeding hopper. The mixing mechanism includes a reduction motor fixedly connected to the side surface of the mixing chamber. The reduction motor is a worm gear reduction motor, and a connecting shaft is fixedly connected to the output shaft of the reduction motor. Multiple sets of scrapers are rotatably connected to the inner wall of the mixing chamber.

[0008] Furthermore, limit rods are fixedly connected to the four corners of the lower surface of the feeding hopper, and the limit rods are slidably connected to the outer surface of the mounting plate.

[0009] By adopting the above technical solution, the vibration direction of the feeding hopper can be precisely constrained by the setting of the four corner limit rods, ensuring that the feeding hopper vibrates only in the vertical direction, avoiding collision damage between the feeding hopper and components such as conveying pipes and mounting plates due to vibration deviation, and preventing raw materials from spilling due to vibration deviation.

[0010] Furthermore, the feeding mechanism also includes a fixed pipe fixedly connected to the upper surface of the mixing tank, the fixed pipe being connected to the inner wall of the mixing tank, and the outer surface of the conveying pipe being slidably connected to the inner wall of the fixed pipe.

[0011] By adopting the above technical solution, the sliding connection structure between the conveying pipe and the fixed pipe can adapt to the positional changes of the feeding hopper during vibration, ensuring that the raw materials always smoothly enter the mixing box through the pipe during the conveying process, and avoiding material leakage due to gaps at the pipe connection caused by the vibration of the feeding hopper.

[0012] Furthermore, the inner wall of the feeding hopper is fixedly connected with a fixed protrusion, which adopts an inverted V-shaped structure.

[0013] By employing the above technical solution, the inverted V-shaped fixed protrusions can divert and disperse the raw materials entering the feeding hopper, preventing them from accumulating in a certain area at the bottom of the hopper and ensuring that the raw materials are evenly distributed and flow towards the conveying pipeline. Furthermore, the inverted V-shaped structure is less prone to material buildup, reducing material residue on the protruding surface and aiding in the crushing of any small lumps in the raw materials, further improving the uniformity of material conveying.

[0014] Furthermore, a discharge valve is fixedly connected to the lower surface of the mixing chamber, and a control panel is fixedly connected to the side surface of the mixing chamber.

[0015] By adopting the above technical solution, the timing and speed of concrete discharge after mixing can be flexibly controlled through the setting of the discharge valve, which is convenient to adjust according to the needs of subsequent construction or transportation, and avoids the concrete from staying in the mixing box for a long time, which would lead to initial setting.

[0016] Furthermore, multiple sets of connecting rods are fixedly connected to the outer surface of the connecting shaft, and the outer surface of the connecting rods is fixedly connected to the outer surface of the scraper.

[0017] By adopting the above technical solution, and using the connecting rod as the intermediate connecting part between the connecting shaft and the scraper, the installation position and number of scrapers can be flexibly adjusted according to the size of the mixing chamber and the stirring requirements, ensuring that the scrapers can cover most of the inner wall of the mixing chamber, thereby improving the stirring and scraping effect.

[0018] Beneficial effects

[0019] This utility model provides a concrete production equipment. Compared with the prior art, it has the following advantages:

[0020] 1. This concrete production equipment uses a mounting plate, springs, and a vibrating motor to drive the feeding hopper to vibrate stably, preventing raw materials such as sand, gravel, and cement from caking and clogging. An inverted V-shaped fixed protrusion helps to divert and disperse the raw materials, reducing residue and aiding in the breaking up of small lumps, ensuring uniform material delivery. Four corner limit rods precisely constrain the vibration direction, preventing the feeding hopper from shifting, colliding, and spilling raw materials. The conveying pipe and fixed pipe are slidably connected to adapt to vibration displacement, preventing leakage and shortening the material conveying path, reducing residue and waste, improving feeding efficiency, and lowering the probability of clogging downtime and maintenance.

[0021] 2. This concrete production equipment uses a worm gear reducer motor to provide a stable and suitable speed, ensuring uniform mixing of raw materials and high efficiency. It also features smooth operation with low noise and self-locking performance, enhancing equipment safety. The connecting shaft is connected to scrapers via multiple sets of connecting rods, allowing for flexible adjustment of the scraper position and quantity to fully cover the inner wall of the mixing chamber. This achieves thorough mixing of raw materials while removing residual concrete from the inner wall. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 4 This application provides a concrete production equipment, including a mixing chamber 1. A feeding mechanism 2 is fixedly connected to the upper surface of the mixing chamber 1, and a mixing mechanism 3 is fixedly connected to the side surface of the mixing chamber 1. The feeding mechanism 2 includes a mounting plate 205 fixedly connected to the upper surface of the mixing chamber 1. Multiple sets of springs 203 are fixedly connected to the upper surface of the mounting plate 205. A feeding bin 206 is fixedly connected to the upper end of the springs 203. A vibration motor 202 is fixedly connected to the lower surface of the feeding bin 206, and a conveying pipe 201 is connected to the side surface of the feeding bin 206. The mixing mechanism 3 includes a reduction motor 302 fixedly connected to the side surface of the mixing chamber 1. The reduction motor 302 is a worm gear reduction motor 302, and a connecting shaft 301 is fixedly connected to the output shaft of the reduction motor 302. Multiple sets of scrapers 304 are rotatably connected to the inner wall of the mixing chamber 1.

[0031] Specifically, limit rods 204 are fixedly connected to the four corners of the lower surface of the feeding hopper 206. The limit rods 204 are slidably connected to the outer surface of the mounting plate 205. The feeding mechanism 2 also includes a fixed pipe 207 fixedly connected to the upper surface of the mixing box 1. The fixed pipe 207 is connected to the inner wall of the mixing box 1, and the outer surface of the conveying pipe 201 is slidably connected to the inner wall of the fixed pipe 207. The inner wall of the feeding hopper 206 is fixedly connected to a fixed protrusion 208, which adopts an inverted V-shaped structure.

[0032] Furthermore, by cooperating with the mounting plate 205, spring 203, and vibration motor 202, the feeding bin 206 is driven to vibrate stably, preventing raw materials such as sand and cement from clumping and clogging. With the inverted V-shaped fixed protrusion 208, the raw materials are diverted and dispersed, reducing residue and assisting in breaking up small lumps, ensuring uniform material delivery. The four corner limit rods 204 precisely constrain the vibration direction, preventing the feeding bin 206 from shifting and colliding, and preventing raw material spillage. The conveying pipe 201 and the fixed pipe 207 are slidably connected to adapt to vibration displacement, preventing material leakage and shortening the raw material conveying path, reducing residue waste, improving feeding efficiency, and reducing the probability of blockage and downtime and maintenance.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, a discharge valve 5 is fixedly connected to the lower surface of the mixing tank 1, and a control panel 4 is fixedly connected to the side surface of the mixing tank 1.

[0034] Specifically, multiple sets of connecting rods 303 are fixedly connected to the outer surface of the connecting shaft 301. The outer surface of the connecting rods 303 is fixedly connected to the outer surface of the scraper 304. The vibration motor 202 is model YZU-10-4, which can adapt to the vibration requirements of the feeding hopper 206, effectively drive the raw materials to disperse, and has stable operation and low energy consumption, making it suitable for concrete raw material feeding scenarios. The geared motor 302 is model RV75, which has the characteristics of high transmission efficiency, smooth operation and low noise, and can provide stable power to the connecting shaft 301 to meet the speed requirements of the scraper 304 for stirring and scraping the wall, and adapt to the working requirements of the mixing mechanism 3. The control panel 4 adopts Xinje XC3-14R-E PLC control panel 4, which supports multi-channel signal input and output and can accurately control the frequency of the vibration motor 202, the speed of the geared motor 302 and the opening and closing of the discharge valve 5.

[0035] Furthermore, the worm gear reducer motor 302 provides a stable and suitable speed, ensuring uniform and efficient mixing of raw materials, smooth operation with low noise, and self-locking performance, thus enhancing equipment safety. The connecting shaft 301 is connected to the scraper 304 through multiple sets of connecting rods 303, allowing for flexible adjustment of the position and number of scrapers 304 to fully cover the inner wall of the mixing chamber 1, achieving both thorough mixing of raw materials and scraping away residual concrete from the inner wall.

[0036] Working principle: The operator starts the equipment through the control panel 4 on the side surface of the mixing box 1, sets the vibration frequency of the vibrating motor 202, the mixing speed of the reduction motor 302 and other parameters. Then, the concrete raw materials are put into the feeding hopper 206. The vibrating motor 202 on the lower surface of the feeding hopper 206 starts to work. With the cooperation of the spring 203, it drives the feeding hopper 206 to generate stable vibration. The raw materials are dispersed under the action of vibration, and at the same time, they are diverted along the inverted V-shaped fixed protrusion 208 on the inner wall of the feeding hopper 206 and flow evenly to the conveying pipe 201. During this process, the four corner limit rods 204 on the lower surface of the feeding hopper 206 slide along the mounting plate 205 to ensure that the feeding hopper 206 does not deviate during vibration. The raw materials enter the fixed pipe 207 through the conveying pipe 201, and then enter the mixing box 1 through the fixed pipe 207. At this time, the worm gear reducer motor 302 on the side surface of the mixing box 1 starts, and its output shaft drives the connecting shaft 301 to rotate. The connecting shaft 301 drives multiple sets of scrapers 304 to rotate along the inner wall of the mixing box 1 through the connecting rod 303. The scrapers 304 fully mix the raw materials entering the mixing box 1, and scrape off the raw material residue on the inner wall of the box to prevent caking. When the concrete raw materials are mixed to the preset requirements, the operator controls the discharge valve 5 on the lower surface of the mixing box 1 to open through the control panel 4. The mixed concrete is discharged through the discharge valve 5 and enters the subsequent construction or conveying stage.
