Description

Technical Field

[0001] This utility model belongs to the field of geological exploration and mineral exploration technology, specifically designing a portable rock and ore density measuring device for field use. Background Technology

[0002] In geological exploration, gravity measurement, mining, and mineral research, rock and ore density is a key parameter for assessing their physical properties, interpreting gravity anomalies, estimating resource reserves, and guiding drilling deployment.

[0003] Currently, conventional measurements of rock and mineral density mostly rely on laboratory environments, using precision balances, graduated cylinders, or specific gravity bottles combined with Archimedes' water displacement method. While these methods offer high accuracy, they are cumbersome, time-consuming, and require strict experimental conditions (such as temperature, horizontal surface, and clean water source), making them unsuitable for field operations. Existing portable density measuring devices attempt to address the field measurement problem, but they generally suffer from complex structures, high costs, poor stability, or insufficient measurement accuracy. Some devices are bulky and heavy, making them inconvenient to carry; others require external power supplies or specialized consumables, limiting their application in remote or infrastructure-free areas. Furthermore, some simple devices lack effective support and stable suspension structures, making them susceptible to interference from wind, vibration, and other environmental factors, affecting weighing accuracy and reducing the reliability of density calculation results.

[0004] Therefore, there is an urgent need to develop a rock and mineral density measuring device that is simple in structure, low in cost, easy to carry, convenient to operate, and can work stably in complex field environments, so as to meet the urgent need for rapid and accurate density data in the front line of geological exploration. Utility Model Content

[0005] The purpose of this invention is to provide a portable rock and ore density measuring device for field use. This device has a simple structure, is easy to carry and operate, and can work stably in field environments without laboratory conditions. It meets the actual needs of geological exploration, mineral evaluation and physical property parameter collection, and solves the problem that rock and ore density measurement is difficult to implement quickly and accurately in the field in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A portable rock and ore density measuring device for field use includes: A measuring container for holding the test solution; A support frame is provided, which integrates a weighing mechanism. The weighing mechanism includes a lifting component and a weighing component. The lifting component is embedded in the support frame and its telescopic end extends to the bottom of the support frame. One end of the weighing component is connected to the telescopic end of the lifting component, and the other end is provided with a suspension platform for placing the object to be tested. The lifting component can drive the weighing component to move the suspension platform up and down, thereby placing or removing the object to be tested from the test liquid in the measuring container.

[0008] As a preferred embodiment of this application: the bottom of the panel is provided with a buckle, and each of the support rods can be stored and fixed to the bottom of the panel through the buckle after disassembly.

[0009] As a preferred embodiment of this application: the bottom of the panel is provided with a receiving cavity for accommodating the electronic crane scale, the receiving cavity being a recessed groove formed at the bottom of the panel, or a frame extending downward from the bottom of the panel.

[0010] As a preferred embodiment of this application, the support rod is a telescopic rod with adjustable length.

[0011] As a preferred embodiment of this application: the suspended platform includes a suspension rod and a load-bearing component. The suspension rod is a solid rod with a diameter of 0.5-1mm and is made of a rigid material. The suspension rod includes one or more rods.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This solution's measuring device includes a measuring container and a support frame integrating a weighing mechanism. The support frame serves as the supporting skeleton of the measuring device, and the integrated weighing mechanism includes a lifting component and a weighing component. The lifting component is fixed to the support frame and drives a suspended platform located below the weighing component to move within the measuring container, thereby achieving two weight measurements ("dry measurement" and "wet measurement") of the test object under different environments. Finally, the density of the test object is obtained based on Archimedes' principle. Therefore, this measuring device not only has high integration and is easy to carry, but also automatically moves the test object within the measuring container via the lifting component. The lifting and moving mechanism within the measuring container improves operational convenience and stability. Furthermore, by adjusting the height of the suspension platform above the measuring container, the sample is immersed in the test liquid, reducing the exposed length of the suspension platform.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0022] Example 1: like Figure 1As shown in this embodiment, a portable rock and mineral density measuring device for field use is provided. The device includes a measuring container 10 and a support frame 20 integrating a weighing mechanism. The measuring container 10 holds a test liquid, such as deionized water or anhydrous ethanol with a known density ρ0. Preferably, the measuring container 10 is a transparent cylindrical structure with a lid and graduations, facilitating direct observation and reading of liquid level changes after the sample is placed in. For portability, the measuring container 10 can be made of lightweight materials. The support frame 20 serves as the overall support skeleton of the measuring device, and its height can be selected according to actual needs, but must be at least greater than the height of the measuring container 10 to facilitate placement of the measuring container 10 at its bottom. The measuring container 10 is placed at the bottom of the support frame 20 and directly below the weighing mechanism. The weighing mechanism is used to obtain the actual weight M1 of the sample in the external environment (a process known as "dry testing") and also to obtain the weight M2 of the sample in the test liquid (a process known as "wet testing"). In this embodiment, the weighing mechanism... Specifically, it includes a lifting assembly 21 and a weighing assembly 22. The lifting assembly 21 is embedded in the support frame 20, and its telescopic end extends to the bottom of the support frame 20 (directly above the measuring container 10). It is understood that the support frame 20 should have an opening for easy embedding of the lifting assembly 21. The lifting assembly 21 can be embedded in the opening using methods such as filling with a buffer pad or interference fit, depending on the actual installation requirements. One end of the weighing assembly 22 is connected to the telescopic end of the lifting assembly 21, and the other end is provided with a suspension platform 2 for placing the object to be measured. 3. That is, the weighing component 22 is fixed at the end of the lifting component 21, and it only weighs the weight of the object to be tested on the suspension platform 23. Compared with the traditional design of placing the measuring container 10 above the weighing component 22, this design reduces the requirements for the weighing range of the weighing component 22 and also reduces the requirements for the load-bearing capacity of the weighing component 22. The lifting component 21 can drive the weighing component 22 to move the suspension platform 23 up and down, thereby placing or removing the object to be tested from the test liquid in the measuring container 10, and finally realizing the dry and wet weight measurement of the object to be tested.

[0023] In this embodiment, the lifting mechanism 21 is either a miniature DC actuator or a manual actuator, preferably the latter, which has higher operational stability and makes the suspended platform 23 less prone to shaking, laying the foundation for accurate "wet measurement". It is understood that the specific model and stroke of the miniature DC actuator can be selected according to the actual data such as the length of the support frame 20, the measuring container 10 and the suspended platform 23. This embodiment does not make specific limitations here. If necessary, a DC actuator of the brand Shaoteng and model ST-801 can be customized and powered by a 12V DC power supply. During installation, the electrical end of the miniature DC actuator is located at the upper end of the support frame 20, and the telescopic rod end extends to the lower part of the support frame 20 through the hole.

[0024] In this embodiment, the weighing component 22 is a combination of a weighing sensor and a digital display unit, or an electronic crane scale. To simplify the structure, this embodiment preferably uses an existing electronic crane scale. The specific model and range of the electronic crane scale can be selected according to actual needs. This embodiment does not make specific limitations here. Any electronic crane scale with high precision, small range, high stability and suitable for suspension operation can be used in this embodiment.

[0025] In this embodiment, the suspension platform 23 includes a suspension rod 231 and a support member 232. The suspension rod 231 is a solid rod with a diameter of 0.5-1mm, and it is made of a rigid material, such as carbon fiber or metal alloy. Compared with traditional thin wires or ropes, the suspension rod 231 made of this rigid material will not wobble, which helps to improve the accuracy of "wet testing". The suspension rod 231 includes one or more rods, which can be selected according to the needs. In this embodiment, it is preferred to include two rods. The support member 232 is connected to the end of the suspension rod 231 to support the object to be tested. The support member 232 is a plate-shaped structure or a bucket-shaped structure. In this embodiment, it is preferred to be a bucket-shaped structure to prevent the object to be tested from falling. It should be noted that the length of the suspension rod 231 should ensure that the weighing component 22 does not come into contact with the test liquid after the object to be tested is completely immersed in the test liquid.

[0026] In specific use of this embodiment: Choose a flat outdoor surface and place the measuring container 10 under the support frame 20 to ensure that the measuring device can be used normally; The sample to be tested is placed on the suspension platform 23 for the first measurement. The actual weight M1 currently displayed on the electronic scale is obtained and recorded. Then, the DC push rod is started again to move the electronic scale, the suspension platform 23 and the sample to be tested downward synchronously until the sample to be tested is completely immersed in the test liquid. At this time, the DC push rod is turned off, and the test weight M2 currently displayed on the electronic scale is obtained and recorded. Then, the following formula is used to calculate based on Archimedes' principle. Combined with the high-precision (±0.01 g) electronic scale and the controllable immersion method, interference factors such as bubbles on the sample surface and contact with the container wall are effectively eliminated, ensuring accurate volume measurement and stable and reliable density results, which meet the accuracy requirements of geological exploration for physical property parameters. The calculation formula is as follows: in, The density of the substance to be measured is To test the liquid density, The actual weight of the object to be measured. The weight of the test object is measured.

[0027] This formula is derived from the following two formulas: (1) (2) According to Archimedes' principle: = Therefore, the above calculation formula can be derived.

[0028] In summary, the measuring device in this embodiment is not only highly integrated and portable, but also automatically moves the object to be tested within the measuring container 10 via the lifting component 21. This improves the convenience and stability of operation. Furthermore, by adjusting the height of the suspension platform 23 from the measuring container 10, the object to be tested is immersed in the test liquid, avoiding interference from harsh outdoor environments such as wind resistance on the stability of the boom 231. Additionally, the rigid structure of the boom 231 further enhances its stability and significantly improves the accuracy of wet testing. Therefore, this embodiment is suitable for outdoor environments without laboratory facilities, meeting the practical needs of geological exploration, mineral evaluation, and physical property parameter collection. It solves the problem of difficulty in quickly and accurately implementing rock and mineral density measurements in the field in existing technologies.

[0029] Example 2: Compared with Embodiment 1, the difference in this embodiment is that the support frame 20 is set as a retractable structure to reduce the volume and make it easy to carry. Specifically, the support frame 20 includes a panel 24 and a support rod 25. The bottom of the panel 24 is provided with a docking interface 241, and the end of the support rod 25 is provided with a connector 251 adapted to the docking interface 241. The support rod 25 is detachably connected to the panel 24 through the connector 251 and the docking interface 241.

[0030] In this embodiment, the mating interface 241 can be any one of a threaded hole, a sleeve hole, or a snap fastener 26, and the mating joint 251 is a structure adapted to the threaded hole, sleeve hole, or snap ring seat. In this embodiment, the mating interface 241 is preferably a threaded hole, which facilitates assembly and disassembly and provides structural stability. Figure 2 As shown.

[0031] In use, the support rod 25 can be fixed to the bottom of the panel 24 by the cooperation of the connector 251 and the mating interface 241, thus completing the construction of the support frame 20. After the measurement is completed, the support rod 25 can be separated from the panel 24, which can reduce the size of the support frame 20 and make it convenient to carry and transport.

[0032] In this embodiment, for ease of use, the support rod 25 is preferably an adjustable telescopic rod. The use of this telescopic rod is not only to adjust the height of the panel 24, but also to make it easier to ensure that the panel 24 is level by adjusting the support rod 25 on uneven ground in the field.

[0033] In this embodiment, a buckle 26 is provided at the bottom of the panel 24. After each support rod 25 is disassembled, it can be stored and fixed at the bottom of the panel 24 through the buckle 26. Figure 3As shown, it can be understood that the buckle 26 can be a pipe clamp, a hoop, or other structure, as long as it can fix the support rod 25. The buckle 26 is used to fix the support rod 25 on the panel 24, which significantly improves the integration of the support frame 20 structure and makes it easier to carry.

[0034] In this embodiment, the bottom of the panel 24 is provided with a receiving cavity 27 for accommodating the electronic crane scale. This receiving cavity 27 is either a recessed groove formed at the bottom of the panel 24, or a frame extending downwards from the bottom of the panel 24. In this embodiment, the latter is preferred. Figure 2 As shown; the enclosure can protect the retracted electronic crane scale. It is understood that in order to prevent damage to the electronic crane scale and the suspended platform 23 during carrying or transportation, a cover can be provided at the opening of the enclosure to form a closed receiving cavity 27. The cover is only opened when in use to expose the electronic crane scale and the suspended platform 23.

[0035] In this embodiment, a flange 28 is preferably provided on at least one side of the outer periphery of the panel to protect the buckle 26 and the receiving cavity 27.

[0036] In summary, this embodiment provides a retractable support frame 20. By storing the support rod 25 and the weighing component 22, the concentration of the support frame 20 can be improved. No additional equipment is required, making it easy to carry later. It can be carried by a single person. At the same time, it can also avoid the loss of structure and thus affect subsequent use. In addition, the bracket in this embodiment is assembled by means of screw connection, buckle 26 and cover, which improves the quickness of disassembly and assembly of the support frame 20.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
