Description

Technical Field

[0001] The utility model relates to the technical field of aggregate particle size counting devices, in particular to an aggregate particle size counting device based on video. Background Art

[0002] Aggregate is an important raw material in construction, road, bridge and other projects. Its particle size distribution has a great impact on the quality of the project. The traditional method of aggregate particle size statistics mainly adopts manual measurement and weighing method. This method is not only inefficient, but also difficult to ensure accuracy. In order to solve the above problems, at present, video statistical devices are usually used to replace manual statistical operations. Video statistical devices can measure the specific particle size of aggregate in the captured video screen through the corresponding calculation method, and display the obtained data on the corresponding display screen after processing. Video statistical devices have the advantages of higher efficiency and more accuracy.

[0003] There are many types of video counting devices on the market. Most of them install video capture cameras above the conveyor belt. The conveyor belt transports aggregates and the video capture camera performs screen capture operations. However, this type of video counting device has the defect of not being able to separate aggregates when in use. If more aggregates are piled together, the upper layer of aggregates will block the lower layer of aggregates, which will affect the normal capture of the capture camera, further affect the subsequent statistical accuracy, and bring inconvenience to users. In view of this, we propose a video-based aggregate particle size counting device. Utility Model Content

The blocking disc 22 is located in the discharge hopper 11, so that when in use, as the blocking disc 22 and the partition 23 rotate, the aggregate entering the material dropping chamber 24 each time is appropriate and not excessive. As the aggregate in the material dropping chamber 24 falls onto the conveyor belt 12, it can be ensured that too much aggregate will not accumulate together, thereby avoiding affecting the normal picture capture of the video acquisition module 14.

[0026] In this embodiment, a threading hole 131 is provided on the support plate 13 , and the threading hole 131 is used for wiring operation.

[0027] Specifically, a support rod 15 is fixedly mounted on the side of the support frame 1 , and the processing host 16 is fixedly mounted on the top of the support rod 15 , so that the processing host 16 can be supported by the support rod 15 .

[0029] In addition, a conveying pipe 3 is fixedly installed on the top surface of the feed hopper 10, and a plurality of nozzles 30 arranged at equal intervals are fixedly installed on the conveying pipe 3. The nozzles 30 are used for water spraying operations, so that when necessary, water can be introduced through the conveying pipe 3. After the water is sprayed out from the nozzle 30, the aggregate can be moistened, thereby reducing the generation of dust and preventing excessive dust from adhering to the video acquisition module 14 and affecting the normal picture capturing operation of the video acquisition module 14.

[0030] It is worth noting that the number of blocking plates 22 is 4 to 8, which are used to separate the aggregates; the video acquisition module 14 is located above the conveyor belt 12, and the video acquisition module 14 faces one side of the conveyor belt 12, so that the video acquisition module 14 can perform picture capture operations normally.

The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0034] When the video-based aggregate particle size counting device of the utility model is in use, after the aggregate is put into the feed hopper 10, the aggregate can fall into the discharge hopper 11. At this time, the drive motor 20 is connected to the external power supply and made to work. When the drive motor 20 works, the output shaft thereon rotates to drive the long shaft 21, the blocking plate 22 and the partition 23 to rotate, so that the aggregate falling into the material dropping chamber 24 each time is appropriate. As the blocking plate 22 and the partition 23 continue to rotate, the aggregate in the material dropping chamber 24 will fall onto the conveyor belt 12, so that the aggregate on the conveyor belt 12 will not be all piled up together, and then the video acquisition module 14, the processing host 16 and the display module 17 are used to perform particle size statistics processing operations, which is convenient to use.
