Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for concrete processing. Background Technology

[0002] Concrete processing refers to the process of mixing raw materials such as cement, sand, gravel, water and admixtures in a specific ratio to produce building materials with predetermined strength and performance. In the concrete processing stage, the raw materials need to be continuously and stably transported to the designated location by a feeding device (such as a belt conveyor).

[0003] During concrete processing, raw materials (such as sand, gravel, recycled aggregates, or bulk cement) often form lumps, agglomerates, or contain oversized particles due to storage environment, transportation process, or their own characteristics. If lumps, agglomerates, or oversized particles in the raw materials directly enter the subsequent processing flow, it may reduce the uniformity of subsequent concrete mixing, thereby affecting the quality of concrete. Therefore, a concrete feeding device is provided to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for concrete processing. By setting up a crushing component, it solves the problem that during the concrete processing process, raw materials often form lumps, agglomerates, or contain oversized particles due to storage environment, transportation process, or their own characteristics. If lumps, agglomerates, or oversized particles in the raw materials directly enter the subsequent processing flow, it may reduce the uniformity of subsequent concrete mixing, thereby affecting the quality of concrete.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a feeding device for concrete processing, including a belt conveyor and a crushing assembly. The belt conveyor is equipped with a feed hopper and a baffle. The crushing assembly is set on the feed hopper and includes a support plate, a first crushing roller and a second crushing roller. There are two support plates, both of which are installed on the feed hopper. A row of toothed grooves is opened on the facing surfaces of the two support plates. The first crushing roller and the second crushing roller are rotatably fitted on the feed hopper. There is a gap between the first crushing roller and the second crushing roller, a gap between the first crushing roller and one of the support plates, and a gap between the second crushing roller and the other support plate.

[0007] Furthermore, the crushing assembly also includes a belt and an L-shaped plate. Both the first crushing roller and the second crushing roller are connected to pulleys, and the two pulleys are connected by a belt. The L-shaped plate is installed on the feed hopper, and a drive source is installed on the L-shaped plate. The first crushing roller is connected to the power output shaft of the drive source.

[0008] Furthermore, the feed hopper has two round holes and two through holes. The two ends of the first crushing roller rotate on the two round holes respectively, and the two ends of the second crushing roller rotate and fit on the through holes respectively.

[0009] Furthermore, multiple baffles are provided, which are evenly distributed on the belt conveyor, and U-shaped grooves are provided on the baffles.

[0010] Furthermore, the feed hopper is designed with openings at both the top and bottom.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up a crushing component, causes concrete raw materials to be squeezed and crushed between the first crushing roller, the second crushing roller, and the toothed groove, so that large pieces of material are crushed into particles that meet the particle size requirements. This solves the problem that in the concrete processing process, raw materials often form lumps, agglomerates, or contain oversized particles due to storage environment, transportation process, or their own characteristics. If lumps, agglomerates, or oversized particles in the raw materials directly enter the subsequent processing flow, it may reduce the uniformity of subsequent concrete mixing, thereby affecting the quality of concrete.

[0013] 2. This utility model uses multiple baffles evenly distributed on the belt conveyor and U-shaped grooves opened on the baffles. The U-shaped grooves can laterally limit the concrete material on the belt conveyor, which can avoid the problem of material spillage caused by belt tilting or vibration during transportation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a concrete processing feeding device, including a belt conveyor 1 and a crushing component 4. The belt conveyor 1 is equipped with a feed hopper 2 and a baffle 3. The belt conveyor 1 is the core conveying component, which can realize the continuous transportation of concrete raw materials. This is the prior art and will not be described in detail here. The feed hopper 2 is bolted to the lower end of the belt conveyor 1. The feed hopper 2 is set with openings at the top and bottom. The funnel-shaped structure with openings at the top and bottom can guide the raw materials to concentrate into the crushing component 4 and avoid material overflow.

[0023] Multiple baffles 3 are provided and are evenly distributed on the belt conveyor 1 by bolts. U-shaped grooves 301 are provided on the baffles 3. The multiple evenly distributed baffles 3 can divide the belt surface into independent units to prevent material accumulation or slippage. The U-shaped grooves 301 can laterally limit the concrete material on the belt conveyor 1 to prevent material from spilling due to belt tilting or vibration during transportation.

[0024] The crushing assembly 4 is mounted on the feed hopper 2. The crushing assembly 4 includes a support plate 401, a first crushing roller 403, and a second crushing roller 404. There are two support plates 401, both of which are bolted to the feed hopper 2. A row of toothed grooves 402 is opened on the facing surfaces of the two support plates 401. The first crushing roller 403 and the second crushing roller 404 are rotatably fitted on the feed hopper 2. There is a gap between the first crushing roller 403 and the second crushing roller 404. There is a gap between the first crushing roller 403 and one of the support plates 401, and there is a gap between the second crushing roller 404 and the other support plate 401. The toothed grooves 402 on the facing surfaces of the two support plates 401 respectively form an meshing shearing structure with the surfaces of the first crushing roller 403 and the second crushing roller 404, which can crush materials outside the gap between the rollers and improve the uniformity of crushing.

[0025] The crushing assembly 4 also includes a belt 405 and an L-shaped plate 407. The first crushing roller 403 and the second crushing roller 404 are both connected to pulleys 406 by keys. The two pulleys 406 are connected by belts 405. The transmission between the two pulleys 406 and belts 405 can drive the first crushing roller 403 and the second crushing roller 404 to rotate synchronously. The L-shaped plate 407 is bolted to the feed hopper 2. A drive source is bolted to the L-shaped plate 407. The drive source can be a suitable AC asynchronous motor. The central shaft of the first crushing roller 403 is connected to the power output shaft of the AC asynchronous motor through a coupling.

[0026] The feed hopper 2 has two round holes 201 and two through holes 202. The two ends of the first crushing roller 403 rotate on the two round holes 201 respectively, and the two ends of the second crushing roller 404 rotate and fit on the through holes 202 respectively. In the crushing assembly 4, through the cooperation of the first crushing roller 403, the second crushing roller 404 with the support plate 401 and the tooth groove 402, large pieces of concrete raw materials (such as lumpy materials or stones with excessive particle size) can be crushed, which facilitates the subsequent processing of concrete.

[0027] During operation, concrete raw materials (such as sand, gravel, cement blocks, etc.) are first fed into the device through the feed hopper 2. The AC asynchronous motor is turned on by the external controller, and the power output shaft of the AC asynchronous motor drives the first crushing roller 403 to rotate through the coupling. Then, the second crushing roller 404 is driven to rotate synchronously through the belt 405 and the pulley 406. The concrete raw materials are crushed between the first crushing roller 403, the second crushing roller 404 and the tooth groove 402, so that large pieces of material are crushed into particles that meet the particle size requirements. Then, they fall into the belt conveyor 1. The belt conveyor 1 is started. The baffles 3 evenly distributed on the surface of the belt conveyor 1 support the crushed material through the U-shaped groove 301. The baffles 3 move with the belt conveyor 1, and the material is conveyed from the lower end to the upper end of the belt conveyor 1. After the material is conveyed to the upper end of the belt conveyor 1, it enters the next process (such as mixing) through the discharge port, thus completing the feeding process.
