Description

Technical Field

[0001] The invention relates to the technical field of concrete production, and in particular to a host video observation device. Background Art

[0002] In the concrete production process, materials such as sand, stone, powder, and liquid configured according to the proportion are mixed and stirred in the main machine to achieve the slump required for production (an important indicator of concrete, representing the key factor of concrete in different use locations). The laboratory personnel responsible for the quality of concrete in the manufacturer make test blocks and visually judge whether the quality of concrete meets the requirements and whether it can be put on the market. It takes four or five days to detect the results of the test blocks, so visually inspecting the slump is the key to determining whether it can be put on the market. The existing mature technology mainly observes the material when the main machine is discharging it into the mixing truck. This is a delayed observation. If there is a deviation in quality, it is necessary to add materials to the vehicle later, and it is difficult to control the accuracy and mixing uniformity. Therefore, it is necessary to observe during the mixing process to facilitate timely micro-adjustments at any time.

[0003] Moreover, the existing host observation port device adopts a barrel-type butterfly valve observation port or a barrel-type gate valve observation port;

[0004] The disadvantage of the barrel-type butterfly valve observation port is that when the butterfly valve is opened, the valve plate is in the middle, and the observation camera can only see one-half of the position, so the observation range is small and the observation effect is not good;

[0005] Due to the switching characteristics of the gate valve, the gate valve can only be installed outside the main housing. In addition, the thickness of the gate valve itself causes the observation camera to be far away from the material, the observation angle is small, and the effect is not good.

[0006] For the above two viewing port devices, the viewing range of the viewing camera cannot reach 30% of the viewing angle of the internal materials of the host.

[0007] Therefore, it is urgent to provide a new host video observation device to solve the above problems existing in the prior art. Summary of the invention
