TECHNICAL FIELD

[0001] The utility model relates to sandstone moisture detection technical field, especially relates to a belt sandstone intermittent moisture detection mechanism. BACKGROUND

[0002] In modern industrial production, especially in the mining, building materials, metallurgy and other industries, belt conveying systems are widely used in the transportation of materials. In these applications, the moisture content of sandstone and other bulk materials is one of the key factors affecting production efficiency and product quality. Too high or too low moisture content can cause problems in the production process, such as material blockage, accelerated equipment wear or reduced product quality. Therefore, real-time monitoring and control of the moisture content of sandstone is of great significance to ensure the smoothness of the production process and product quality.

[0003] Traditional moisture detection methods usually rely on manual sampling and laboratory analysis, but this method is time-consuming and inefficient, and cannot achieve online continuous monitoring. After searching, "a sandstone moisture automatic detection device, authorization announcement number: CN219016231U", the utility model discloses a water moisture detection mechanism is driven by using automatic mechanism and lifting mechanism instead of manual sandstone in the car to carry out moisture detection, solves the technical problem of long time consumption and low efficiency of traditional moisture detection method. But the above-mentioned sandstone moisture automatic detection device needs to wait for the sandstone loaded truck to stop under the detection support before use, which cannot realize online continuous monitoring of the moving sandstone moisture. SUMMARY

[0004] In view of the deficiencies of the prior art, the technical problem solved by the utility model is to provide a belt sandstone intermittent moisture detection mechanism to solve the problem of long time consumption, low efficiency and inability to realize online continuous monitoring of the existing detection method.

[0005] In order to solve the above problems, the utility model adopts the technical scheme: a belt sandstone intermittent moisture detection mechanism, characterized by: including crossbeam, horizontal moving device, vertical telescopic device, moisture detection device, the longitudinal axis direction of crossbeam is perpendicular to the sandstone moving direction; The horizontal moving device is installed on the crossbeam; The vertical telescopic device is fixed on the horizontal moving device; The moisture detection device is fixed at the lower end of the vertical telescopic device; The moisture detection device includes a protective cover and a humidity sensor, the protective cover includes a containment structure and an arc plate, the containment structure surrounds the humidity sensor and the bottom of the containment structure is perforated; The arc plate is rectangular in shape, the width of the rectangle is consistent with the width of the containment structure, one end of the arc plate is bent upward to form a semicircular arc, and the other end is connected with the containment structure; The arc plate is arranged in the opposite direction of the sandstone moving direction; The humidity sensor is installed in the containment structure.

[0006] The technical principle behind this solution is as follows: by using a horizontal moving device and a vertical telescopic device, the moisture detection device is positioned in space, allowing it to be placed in a suitable location for continuous online monitoring of the moisture content of the constantly moving sand and gravel.

[0007] The beneficial effects of this solution are as follows: By using a horizontal moving device and a vertical telescopic device, the moisture detection mechanism can be positioned at a fixed spatial location to continuously detect the constantly moving sand and gravel, shortening the detection time and improving detection efficiency; this technical solution can monitor the moisture content of materials in real time, providing continuous data support for the production process, helping to identify problems in a timely manner and make adjustments to ensure product quality; the design of the protective cover can unify the detection surface height of the sand and gravel being tested, increasing the accuracy of detection, while also preventing materials from directly impacting the humidity sensor, extending the service life of the detection equipment.

[0008] Furthermore, the enclosure structure is a hexahedral or cylindrical structure, with an openable top cover at the top. The top cover is connected to the enclosure structure via a hinge, and a locking device is provided in the opening direction of the top cover to control its opening and closing. The openable and closable top cover facilitates the installation and maintenance of the humidity sensor within the enclosure structure.

[0009] Furthermore, the arc-shaped plate is trapezoidal or fan-shaped and curves upward to form a semi-circular arc, with the width of one end being greater than the end connected to the retaining structure. This makes the width of the detection surface of the sand and gravel being tested greater than the width of the retaining structure, increasing the accuracy of the detection.

[0010] Furthermore, a humidity sensor installed within the enclosure structure is connected to a monitoring display screen to enable continuous online monitoring of the moisture content of the sand and gravel being tested. Attached Figure Description

Specific embodiments:

[0018] First, install the beam 2 above the moving sandstone 8, so that the longitudinal direction of the beam 2 and the moving direction of the sandstone 8 are perpendicular to each other, so that the moisture detection device can cover the moving sandstone 8.

[0019] Then install the horizontal moving device 3 on the beam 2, so that the moisture detection device can move back and forth along the longitudinal direction of the beam 2 to meet the water detection needs of sandstone 8 at different positions. There are many ways to realize horizontal movement, here are three common methods; Method 1: gear and rack device, the rotation of the gear drives the straight line movement of the rack, install the gear and rack on the beam 2, then drive the gear to rotate by the motor, realize the straight line movement of the rack; Method 2: electric push rod device, the electric push rod is fixedly installed at one end of the beam, and the power supply and controller are connected, the electric push rod is controlled to stretch and retract by sending instructions through the controller; Method 3: ball screw device, composed of screw rod and nut, the screw rod is provided with ball, first install the screw rod and nut, the axial direction of the screw rod is consistent with the longitudinal direction of the beam, then drive the screw rod to rotate by the external driving mechanism (such as servo motor), so that the nut moves along the axial direction of the screw rod.

[0020] Next, the vertical telescopic device 4 is fixed on the horizontal moving device 3, so that the moisture detection device can be lifted in the vertical direction to adapt to the moisture detection requirements of sandstone 8 of different heights.
