Description

Technical Field

[0001] This utility model relates to the field of aggregate production and testing technology, specifically to an aggregate oversize detection device. Background Technology

[0002] An aggregate oversize detection device is a high-precision, automated testing equipment based on modern sensing and computer processing technologies. It is mainly used in concrete mixing plants, hydropower station aggregate processing systems, asphalt mixing plants, and other similar locations to monitor the aggregate size on conveyor belts in real time and online. It automatically identifies and counts "oversize" aggregates exceeding preset specifications, thus achieving key control over aggregate quality. This aggregate oversize detection device is one of the key pieces of equipment for the modern building materials industry to move towards intelligence and automation. Like a tireless "quality supervisor," it works 24 / 7 on the production line, fundamentally improving the quality stability of aggregate products and laying a solid foundation for building high-quality projects. However, existing aggregate oversize detection devices still have certain shortcomings. While a traditional aggregate oversize detection device can be used effectively, when using multi-layer sieves, after screening, it is necessary to separate and collect each layer of aggregate. This separation and dumping process can easily cause aggregates of different sizes to splash and mix together. Especially when collecting the bottom layer of fine material, material from the upper layer may fall in, which seriously affects the accuracy of the test results, makes it inconvenient for staff to use, and often troubles users. Utility Model Content

[0003] The purpose of this invention is to provide an aggregate oversize detection device to solve the problem mentioned in the background art, which is that when using a multi-layer sieve, after screening, it is necessary to separate and collect each layer of aggregate. This separation and pouring process can easily cause aggregates of different sizes to splash and mix with each other. Especially when collecting the bottom layer of fine material, the material from the upper layer may fall in, which seriously affects the accuracy of the detection results, is inconvenient for operators, and often troubles users.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aggregate oversize detection device, comprising a tank, an oversize detection mechanism, and a vibration conveying mechanism. The tank is provided with the oversize detection mechanism and the vibration conveying mechanism, which is located above the oversize detection mechanism. The oversize detection mechanism includes a large-pore filter plate, a medium-pore filter plate, a small-pore filter plate, fixing bolts, a fixing frame, a servo motor, a rotating shaft, a driven spur gear, a driving spur gear, a rotating rod, a turntable, and a through hole. The interior of the tank is provided with a large-hole filter plate, a medium-hole filter plate and a small-hole filter plate from top to bottom. The large-hole filter plate, the medium-hole filter plate and the small-hole filter plate are all slidably connected to the tank. The tank is rotatably connected with a fixing bolt, which is threaded to the large-hole filter plate, the medium-hole filter plate and the small-hole filter plate respectively. The tank has three sets of discharge holes. The tank is equipped with a vibrating conveyor mechanism for feeding materials.

[0009] As a preferred embodiment of this utility model, the tank body is hinged with a conveying groove, and the conveying groove is slidably connected to the cam.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This aggregate oversize detection device adopts a fixedly installed multi-layer filter plate of different specifications, with a clear screening path, ensuring the accuracy and consistency of particle size classification. The vibration feeding method enables the aggregate to be evenly distributed on the screen surface, preventing accumulation and allowing each aggregate to have the opportunity to pass through the corresponding screen hole, reducing detection errors. Furthermore, the innovative rotary table discharge mechanism is a core advantage. Through the precise control of the rotary table rotation by a servo motor, different levels of discharge ports can be opened as needed and in sequence.

[0013] 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.

[0014] Please see Figure 1-3 This utility model provides a technical solution: an aggregate oversize detection device, including a tank 1, an oversize detection mechanism 2, and a vibration conveying mechanism 3. The oversize detection mechanism 2 and the vibration conveying mechanism 3 are arranged on the tank 1, with the vibration conveying mechanism 3 located above the oversize detection mechanism 2. The oversize detection mechanism 2 includes a large-hole filter plate 201, a medium-hole filter plate 202, a small-hole filter plate 203, a fixing bolt 204, a fixing frame 205, a servo motor 206, a rotating shaft 207, a driven spur gear 208, a driving spur gear 209, a rotating rod 210, a turntable 211, and a through hole 212. The interior of the tank 1 is provided with a large-hole filter plate 201, a medium-hole filter plate 202 and a small-hole filter plate 203 from top to bottom. The large-hole filter plate 201, the medium-hole filter plate 202 and the small-hole filter plate 203 are all slidably connected to the tank 1. The tank 1 is rotatably connected with a fixing bolt 204, which is threadedly connected to the large-hole filter plate 201, the medium-hole filter plate 202 and the small-hole filter plate 203 respectively. The tank 1 has three sets of discharge holes. The tank body 1 is equipped with a vibrating conveyor mechanism 3 for feeding materials.

[0015] Three sets of fixing brackets 205 are fixedly installed on the tank body 1. A servo motor 206 is fixedly installed on the fixing bracket 205. A rotating rod 210 is fixedly installed on the output end of the servo motor 206. A drive spur gear 209 is fixedly installed on the rotating rod 210.

[0016] A driven spur gear 208 meshes with the driving spur gear 209. The driven spur gear 208 is connected to the tank body 1 via a rotating shaft 207. A turntable 211 is fixedly installed on the rotating shaft 207. Two sets of through holes 212 are opened on the turntable 211, and the size of the through holes 212 is slightly larger than the discharge hole opened on the tank body 1.

[0017] The vibrating conveying mechanism 3 includes a support frame 301, a drive motor 302, a drive shaft 303, a cam 304, and a conveying trough 305. The support frame 301 is fixedly installed on the tank body 1, and the drive motor 302 is fixedly installed on the support frame 301.

[0018] A drive shaft 303 is fixedly installed at the output end of the drive motor 302, and two sets of cams 304 are fixedly installed on the drive shaft 303.

[0019] A conveying groove 305 is hinged to the tank body 1, and the conveying groove 305 is slidably connected to the cam 304.

[0020] Working principle: When using an aggregate oversize detection device, first start the drive motor 302 to drive the drive shaft 303 and the cam 304 on it to rotate. The rotation of the cam 304 periodically pushes up the conveying trough 305 that is slidably connected to it. Since the conveying trough 305 is hinged to the tank 1, it falls back under its own gravity, thereby generating continuous high-frequency vibration. This vibration will uniformly and continuously transport the aggregate placed on the conveying trough 305 to the screening area inside the tank 1. Under the influence of gravity, the aggregate first falls onto the large-pore filter plate 201. Aggregates with a particle size smaller than the large pore size fall onto the medium-pore filter plate 202, while oversized aggregates are retained on the large-pore filter plate 201, completing the first stage of oversized particle detection and separation. Similarly, the aggregates then pass through the medium-pore filter plate 202 and the small-pore filter plate 203 in sequence, achieving precise screening and detection of medium and small particle sizes. Finally, the aggregates are precisely divided into four grades: oversized oversized aggregates, medium-sized aggregates, small-sized aggregates, and dust. After screening, the aggregates of each grade need to be discharged separately. By starting the servo motor 206, the rotating rod 210 and the driving spur gear 209 are driven to rotate. The driving spur gear 209 drives the driven spur gear 208, which in turn rotates the rotating shaft 207 and the turntable 211 fixed thereon. The turntable 211 has through holes 212. When the turntable 211 rotates until its through hole 212 aligns with the discharge hole on the side wall of the tank 1, the aggregates of the corresponding layer, such as oversized aggregates remaining on the large-pore filter plate 201, can be discharged through this channel. By controlling the rotation angle of the servo motor 206, different discharge holes can be opened sequentially and selectively, achieving the classification and targeted collection of aggregates of each grade, avoiding mixing and contamination, thus completing a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
