[0002] Forest fires pose a serious threat to the ecological environment and the safety of human life and property. The moisture content of forest surface combustibles is one of the key factors affecting the occurrence, development and spread of forest fires. Accurately and quickly measuring the moisture content of forest surface combustibles is of great significance for the prevention, monitoring and effective extinguishment of forest fires.

[0003] At present, the main method for measuring the moisture content of forest combustibles is still the traditional drying method. This method requires high equipment, is cumbersome to operate, and takes a long time, making it difficult to meet the needs of field real-time monitoring. Currently, some existing rapid measurement instruments have problems such as inaccurate measurement, high requirements for samples, being relatively bulky and not portable, unable to adapt to complex field environments, and lacking strong pertinence for small forest surface combustibles, and unable to effectively penetrate into the shallow layer of the surface to obtain representative samples for accurate measurement.

[0004] Therefore, there is an urgent need for a device for measuring the moisture content of forest surface combustibles that can be quickly, accurately and easily operated in the wild to overcome the above problems.

[0005] In view of this, the present application is specifically proposed. Summary of the Invention

[0010] A process processing component, which is arranged on the side of the sampling component away from the forest ground surface; the process processing component performs compression, drying, and grinding operations on the surface layer of the combustible materials to be processed, and the surface layer of the combustible materials to be processed forms processed combustible residue after the processing operations; during the sampling stage, the sampling component rotates relative to the process processing component;

[0011] A weighing component, which is used to obtain the weight information of the forest ground surface sampling, the surface layer of the combustible materials to be processed, and the processed combustible residue;

[0012] Wherein, the information detection, processing, and control component obtains the moisture content of the forest ground surface combustibles according to the weight information obtained by the weighing component.

[0013] After adopting the above technical solution, compared with the prior art, the present invention has the following beneficial effects: By applying the device for measuring the moisture content of forest ground surface combustibles of the present invention, by monitoring the weight change of the surface layer of the combustible materials to be processed before and after processing in stages, the moisture content of the forest ground surface combustibles can be measured quickly and accurately.

[0033] The forest floor is divided into a litter layer, a humus layer, and a soil layer from top to bottom. The litter layer is mainly composed of organic substances such as fallen leaves, dead branches, tree bark, fruits, and withered flowers of trees and other plants in the forest. The humus layer is a layer of black or dark brown organic substances gradually formed by the decomposition and transformation of litter by microorganisms and the fragmentation and mixing of soil animals. Detecting the moisture content of the litter layer and humus layer on the forest floor is of great significance for the prevention, monitoring, and effective extinguishing of forest fires.

[0147] In a specific implementation manner of this embodiment, the depth at which the sampling component 1 screws into the forest floor is also displayed on the display screen 51 of the display component 5 (for example, a distance sensor is provided at one end of the process processing component 3 close to the sampling component 1 or at one end of the sampling component 1 close to the process processing component 3, and the distance sensor detects the distance between it and the forest floor; the total control center 22 pre-stores the distance between the distance sensor and the end of the sampling component 1 far from the process processing component 3; the depth at which the sampling component 1 screws into the forest floor is obtained by the difference between the pre-stored distance and the distance detected by the distance sensor between it and the forest floor).

[0149] The compression process is carried out before the heating process and the grinding process;

[0150] Either the heating process or the grinding process can be given priority, with the other process running later, or the two processes can be carried out simultaneously (heating while grinding).

[0151] Please refer to Appendix Figure 4 to Appendix Figure 11, in a specific implementation manner of this embodiment, the driving component 7 includes:

[0152] A first motor 71, the first motor 71 drives the sampling component 1 to rotate relative to the process processing component 3;

[0153] A second motor 72, the second motor 72 drives the grinding head 331 of the grinding assembly 33 to rotate circumferentially.

[0154] In a specific implementation manner of this embodiment, the first motor 71 of the driving component 7 is disposed in the annular accommodating cavity 35, and the rotating shaft of the first motor 71 (towards the direction close to the sampling component 1) extends out of the annular accommodating cavity 35;

[0155] A first transmission gear 711 is disposed on the rotating shaft of the first motor 71 extending out of the annular accommodating cavity 35;

[0158] The plurality of first motors 71 are arranged in an annular array;

[0159] The first transmission gears 711 on the rotating shafts of the plurality of first motors 71 are all meshed with the same second transmission gear 14 for transmission.

[0160] In a specific implementation manner of this embodiment, an annular shielding plate 122 is further disposed on the outer periphery of the second part 12, and the outer diameter of the shielding plate 122 is greater than or equal to the outer diameter of the process processing component 3;

[0161] The shielding plate 122 is disposed at a position between the blade 121 (the end close to the process processing component 3) and the second transmission gear 14.

[0162] In the present invention, by providing the shielding plate 122, when sampling a sample, it is avoided that the forest floor contacts the gears (the first transmission gear 711 and the second transmission gear 14), which affects the normal rotation of the sampling component 1; meanwhile, the setting of the shielding plate 122 limits the deepest sampling depth of the sampling component 1.

[0163] In a specific implementation manner of this embodiment, the second motor 72 is disposed in the support member 6 (disposed at one end of the support member 6 close to the process processing member 3);

[0164] The rotating shaft portion of the second motor 72 extends out of the support member 6 and extends into the process processing channel 34. A grinding head 331 is disposed on the rotating shaft of the second motor 72 located in the processing channel 34.

[0165] In a specific implementation manner of this embodiment, a sealed deep groove ball bearing is disposed at a position where the rotating shaft of the second motor 72 is adjacent to the support member 6 and / or the process processing member 3.

[0166] In another specific implementation manner of this embodiment, the axis of the rotating shaft of the second motor 72 is collinear with the axis of the process processing channel 34.

[0167] In another specific implementation manner of this embodiment, the axis of the rotating shaft of the second motor 72 is parallel to the axis of the process processing channel 34, and the axis of the rotating shaft of the second motor 72 is not collinear with the axis of the process processing channel 34, that is: the grinding head 331 is offset in the processing channel 34.

[0168] In this application, by providing the offset grinding head 331, grinding can be better performed; drying and grinding cooperate with each other to more fully remove moisture and ensure the accuracy and reliability of moisture content detection.

[0169] Please refer to the append Figure 5 and the append Figure 11 , in a specific implementation manner of this embodiment, the heating assembly 32 further includes:

[0170] A temperature control member 322, and the temperature measuring head of the temperature control member 322 is attached to the peripheral wall of the channel of the process processing channel 34 or inside the peripheral wall of the channel (a receiving groove recessed toward the axis direction close to the process processing channel 34 is provided on the peripheral wall of the channel) to detect the temperature inside the process processing channel 34;

[0171] When the process processing member 3 is in the drying stage and / or the grinding stage of the combustible surface layer to be processed, the total control center 22 controls the on / off (power on and power off) of the heating wire 321 according to the temperature information detected by the temperature control member 322 to control the temperature inside the process processing channel 34 within a preset temperature range (for example, controlling the temperature inside the process processing channel 34 to be greater than 50 °C and less than or equal to 105 °C).

[0172] In a specific implementation manner of this embodiment, in the drying stage, the temperature inside the process processing channel 34 is controlled at 105 °C for 2 minutes.

[0173] In a specific implementation manner of this embodiment, after drying treatment at (105°C, 2 min), its weight is detected.

[0174] After detecting the weight, drying (short-time) is carried out again at (105°C, 10 s), and then its weight is detected.

[0175] If the difference between the mass detected in the latter time and the mass detected in the former time is less than the preset standard difference (for example, 0.01 g), it means that the drying is completed, and the mass detected in the latter time is taken as the weight of the combustible residue after treatment; if the difference between the mass detected in the latter time and the mass detected in the former time is greater than the preset standard difference, the above-mentioned (short-time) drying at (105°C, 10 s) is repeated to detect its weight until the difference between the mass detected in the latter time and the mass detected in the former time is less than the preset standard difference.

[0176] In a specific implementation manner of this embodiment, a heat insulation material is attached to the outer cavity wall of the annular accommodation cavity 35 (the side wall away from the peripheral wall of the treatment channel 34); the setting of the heat insulation material prevents heat dissipation from resulting in low drying efficiency and heat overflow from scalding the operator.

[0177] In a specific implementation manner of this embodiment, both the temperature control member 322 and the heating wire 321 are arranged inside the peripheral wall of the channel.

[0178] And the distance from the temperature control member 322 to the axis of the treatment channel 34 is less than the distance from the heating wire 321 to the axis of the treatment channel 34.

[0179] When using the device for measuring the moisture content of forest surface combustibles provided by this application, the user holds the handle part 61 of the measuring device, faces the sampling part 1 towards the forest surface, and the sampling part 1 rotates and drills into the forest surface to obtain a forest surface sample.

[0180] The information detection, processing and control component 2 starts to determine the junction of the humus layer and the soil layer; the layering component is controlled to layer, and the separating plate 15 is inserted into the junction of the humus layer and the soil layer; at this time, the measuring device automatically discharges the soil layer (or the user manually shakes it out) to form a combustible surface layer to be processed, and the weighing plate of the weighing component 4 extends into the sampling channel 111 (at this node, the weighing plate is closer to the forest surface than the separating plate), and the separating plate retracts into the inner cavity.

[0181] After weighing (obtaining the wet weight), the separating plate pushes the combustible surface layer to be processed into the treatment channel 34 (at this node, the newly inserted position of the separating plate is closer to the forest surface than the weighing plate).

[0182] The process processing component 3 performs compression processing, drying processing, and grinding processing on the surface layer of the combustible material to be processed, forming the residue of the processed combustible material.

[0183] At this time, the weighing plate of the weighing component 4 weighs again (obtaining the dry weight).

[0184] The information detection, processing, and control component 2 calculates the moisture content of the combustible material on the forest surface based on the obtained weight information.

[0185] By applying the device for measuring the moisture content of the combustible material on the forest surface described in the present invention, the weight change of the surface layer of the combustible material to be processed before and after treatment is monitored in stages. The miniaturized design is not only convenient for carrying but also realizes the rapid and accurate measurement of the moisture content of the combustible material on the forest surface.
