DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0024] The utility model provides a rapid detection device for the mud content on the surface of rockfill, referring to Figure 1 ,include

[0025] A load-bearing frame 1, the bottom of which is used to bear the rock pile containing soil, and a weight sensor 11 for detecting the weight of the rock pile is provided on the legs 13 below the load-bearing frame 1;

[0026] The flushing assembly 2 includes a water reservoir 21, a pumping device 22, a flushing pipeline 23 and a nozzle 24. The water inlet end of the pumping device 22 is connected to the inside of the water reservoir 21. The nozzle 24 is arranged on the side of the supporting frame 1. One end of the flushing pipeline 23 is connected to the nozzle 24, and the other end is connected to the water outlet end of the pumping device 22. The pumping device 22 is used to pump water in the water reservoir 21 into the flushing pipeline 23, and then spray it along the nozzle 24 to flush the rock pile containing soil on the supporting frame 1; and

[0027] The air drying assembly 3 includes an air blowing device 31 and an air flow pipeline 32. The air outlet of the air flow pipeline 32 is connected to the nozzle 24, and the air blowing device 31 is connected to the air inlet of the air flow pipeline 32 for air drying the flushed rock pile surface.

[0028] Specifically, the supporting frame 1 is the basic structure of the device, and its bottom is used to support the rock pile containing soil. The weight sensor 11 installed on the support leg 13 below the supporting frame 1 is used to accurately measure the weight of the rock pile. The supporting frame 1 provided in this embodiment is opposite to the upper, lower, left and right sides of the rock pile. The flushing assembly 2 is the core part of the device, wherein the water reservoir 21 is used to store water resources required for flushing, one end of the pumping device 22 is connected to the inside of the water reservoir 21 to ensure sufficient water supply, a plurality of nozzles 24 are provided, and the plurality of nozzles 24 are designed on the peripheral side of the supporting frame 1, facing the upper, lower, left and right outer surfaces of the rock pile; the water outlet end of the flushing pipeline 23 is connected to the nozzle 24, and the water inlet end is connected to the other end of the pumping device 22, forming a complete water system; when the pumping device 22 is started, the water in the water reservoir 21 is pumped into the flushing pipeline 23, and then sprayed out along the nozzle 24, so as to strongly flush the rock pile containing mud on the supporting frame 1, and flush the mud on the surface of the rock pile to the outside of the supporting frame 1. The air drying component 3 is responsible for air drying the surface of the flushed rock pile. When the flushing is completed, the air blowing device 31 is started to blow air into the air flow pipeline 32, and then blow it to the surface of the rock pile through the nozzle 24 to dry the remaining moisture. During this period, the weight fluctuation of the stone is monitored in real time through the weight sensor 11. The device can realize rapid and accurate detection of the mud content of the stone sample through the steps of weighing, flushing, air drying and final weighing.

[0029] When the rock pile is washed, a large amount of water is used to remove impurities and dirt on the surface of the stone. In the traditional treatment method, the used water is often directly discharged, resulting in a waste of water resources. However, in this embodiment, the water reservoir 21 and the supporting frame 1 are set to have a certain height difference, so that the water used to wash the rock pile can flow back into the water reservoir 21 along the slope between the water reservoir 21 and the supporting frame 1, and the water used to wash the stone can flow back into the water reservoir 21. The water returned to the water reservoir 21 can be used again to wash the stone or for other purposes after being properly treated. This secondary utilization method not only improves the utilization efficiency of water resources, but also reduces engineering costs and environmental pollution.

[0030] In addition, a bearing plate 12 is installed at the bottom of the bearing frame 1. The bearing plate 12 is provided with through holes. The aperture of the through holes is smaller than the minimum particle size of the piled rocks. Firstly, it is convenient for drainage. Secondly, it allows the small-diameter rocks to fall onto the bearing plate 12 for easy collection.

[0031] In this embodiment, the bearing frame 1 is made of steel material. The steel material is widely used in various buildings and mechanical structures due to its high strength, good shaping ability and corrosion resistance. During the processing and manufacturing process of the steel material, the required structural shape can be accurately shaped according to actual needs through cutting, welding, drilling and other processes to ensure the stability and durability of the bearing frame 1. In addition, in this embodiment, a high-pressure blower is used as the blowing device 31. The high-pressure blower has the characteristics of large air volume and high pressure, which can effectively provide the required air flow for the system and accelerate the air drying rate of the rock pile surface; a water pump is selected as the pumping device 22 of this embodiment. The water pump is widely used in various water conservancy projects and irrigation systems due to its advantages of high pumping efficiency, low energy consumption and simple operation. The water pump is driven by an electric motor to pump water from a low place to a high place or from a far place to a near place, which can meet the water demand. Therefore, the selection of these equipment and materials can ensure the stability and efficiency of the overall operation of the device.

[0032] In addition, compared with other electronic devices, the weight sensor 11 requires relatively less power. Even in the absence of an external power supply, the weight sensor 11 can run for a long time through its own integrated battery. This low energy consumption feature enables the weight sensor 11 to maintain a stable operating state when it needs to work for a long time or cannot be stably connected to a power supply. It can also be connected to an external power supply. In addition, a waterproof layer is provided on the outside of the weight sensor 11, so that the weight sensor 11 can also work normally in a humid or underwater environment. The waterproof layer can be made of materials such as silicone rubber and fluororubber. The rubber material has excellent elasticity, heat resistance and corrosion resistance, and can provide additional protection to effectively prevent the sensor from being mechanically damaged. In addition, the weight sensor 11 can be connected to the control panel (displayed by a liquid crystal or dot matrix display device, controlled by a single-chip microcomputer or an industrial computer) by wired or wireless means, and a small program or app can be developed to connect to the mobile phone, so that the weight data can be viewed through the mobile phone anytime and anywhere, and remote monitoring and management can be achieved. This intelligent connection method can greatly improve work efficiency.

[0033] The flushing pipeline 23 and the airflow pipeline 32 can adopt a common setting or be laid out separately. The common setting means that the flushing pipeline 23 and the airflow pipeline 32 adopt the same system, which can save space, reduce costs and simplify maintenance; while if they are laid out separately, the needs of different pipelines can be better met to ensure that the flushing and airflow effects are optimal, but this method may also lead to problems such as increased costs and more space occupation. In addition, when they are laid out separately, valves for controlling the opening and closing of the pipelines are provided on the flushing pipeline 23 and the airflow pipeline 32, which respectively control the opening and closing of the corresponding pipelines to ensure that water does not flow into the airflow pipeline; no matter which method is adopted, the core control element is uniform distribution and the layout density should not be too low to affect the flushing / air-drying effect, so as to ensure that every place that needs flushing or airflow can be fully treated. In addition, the flushing pipeline 23 and the airflow pipeline 32 can be made of plastic materials (such as polyethylene, polypropylene, etc.) or rubber materials (such as rubber or polyurethane, etc.), which can effectively prevent liquid or gas leakage.

[0034] The operation method of the device for rapid detection of mud content on the surface of rockfill provided in the utility model is as follows:

[0035] (1) Before loading the stone, first perform the initial weighing and record the total weight as M0;

[0036] (2) Load the stone sample into the device, ensuring that it is evenly loaded; after loading, weigh it again and record the total weight at this time as M1;

[0037] (3) After loading the stone, open the flushing equipment to flush the stone; the flushing time is controlled within 3 to 5 minutes to ensure that the soil on the surface of the stone is fully washed away;

[0038] (4) After the flushing is completed, the flushing equipment is turned off and the air drying equipment is immediately turned on. The air drying time is set to 5 to 10 minutes. During this period, the weight fluctuation of the stone is monitored in real time by the weight sensor 11. When the weight fluctuation is less than one thousandth of the total mass, it can be considered that the stone has been air dried. This auxiliary judgment standard helps to improve the accuracy of the detection.

[0039] (5) After air drying is completed, record the final air-dried mass M2 of the device;

[0040] (6) Calculate the mud content of the rockfill according to the formula (M1-M2) / M2 and output the result.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
