[0002] Soil crusts are divided into biological crusts and physical crusts. Soil biological crusts are complex aggregates formed by the compounding of mosses, algae, fungi, bacteria, and many non-vascular plant components common in landscapes with a very thin soil layer below; soil physical crusts are structural crusts formed by the physical changes of soil aggregates caused by rainfall hitting and compacting the surface soil.

[0003] After retrieval, a soil hardness detection device disclosed in a Chinese patent with the publication number CN218180475U includes a detector. The bottom end of the detector is fixedly installed with an assembly table, and two assembly rods are movably installed at the bottom end of the assembly table. The bottom end of the assembly rod closer to the lower part is movably installed with a drill bit. The utility model is through the cooperation of an assembly buckle and an assembly groove. Subsequently, the assembly buckle is snapped into the interior of the assembly groove, and the spring buckle is loosened. The spring buckle will pop out under the elastic potential energy of the compression spring and snap into the interior of the through hole, thereby completing the installation between the assembly rods.

[0004] Although the hardness of the soil can be detected in the above patent, it is difficult for the hardness detection device in the above patent to press the surrounding of the detected soil. When detecting the soil crust, it is easy to drive the surrounding soil to move; for this reason, we provide a strength testing device for biological soil crust in sandy land to solve the above problems.

[0030] An embodiment of the present utility model provides a device for testing the strength of biological soil crust in sandy land.

[0031] Please refer to Figure 3 and Figure 6 , which includes a base 1. A strength testing mechanism 3 is arranged on the upper surface of the base 1. The strength testing mechanism 3 includes a fixed support 301 fixedly connected to the upper surface of the base 1. The upper end of one side of the fixed support 301 is fixedly connected to one side of a second fixed shell 302. The inside of the second fixed shell 302 is fixedly connected to the fixed end of a second electric telescopic rod 303. The telescopic end of the second electric telescopic rod 303 is fixedly connected to one side of a slide plate 304. The middle part of the lower surface of the slide plate 304 is fixedly connected to the fixed end of a third electric telescopic rod 306. The telescopic end of the third electric telescopic rod 306 is fixedly connected to the middle part of the upper surface of a third fixed plate 308. When it is necessary to detect the soil crust, the third electric telescopic rod 306 is used to push the third fixed plate 308 down, and the equipment on the third fixed plate 308 is used to detect the soil crust.

[0032] The upper surface of the third fixing plate 308 is fixedly connected to one end of the first guiding rod 307. The outer circumferential surface of the first guiding rod 307 is slidably connected to the inside of the second fixing plate 305. The lower surface of the second fixing plate 305 is fixedly connected to the lower surface of the sliding plate 304. The sliding plate 304 and the second fixing plate 305 clamp the groove of the second fixing shell 302, which facilitates reciprocating sliding when the position of the strength testing mechanism 3 is moved for detection. The first guiding rod 307 can guide the third fixing plate 308 to prevent the third fixing plate 308 from tilting during up and down movement. The middle part of the lower surface of the third fixing plate 308 is fixedly connected to the upper surface of the detection device 309. The lower surface of the detection device 309 is fixedly connected to the upper surface of the fourth fixing plate 310. The lower surface of the fourth fixing plate 310 is fixedly connected to the upper end of the cutter 311. After the third electric telescopic rod 306 pushes the third fixing plate 308 to descend, the cutter 311 cuts the soil crust, and the detection device 309 collects the force of the cutter 311 cutting the soil, with an ideal detection effect.

[0033] Please refer to Figure 4 and Figure 5 , one end of the sliding plate 304 is slidably connected to the inside of the second fixing shell 302. After the detection of one area is completed, the second electric telescopic rod 303 pushes the sliding plate 304 to reciprocate in the groove inside the second fixing shell 302, which facilitates the detection of different areas. The fourth fixing plate 310 supports and fixes the second fixing shell 302, playing a fixing role. A chute 101 is provided on the lower surface of the base 1. One side of the inside of the chute 101 is fixedly connected to the fixed end of the first electric telescopic rod 209. The telescopic end of the first electric telescopic rod 209 is fixedly connected to one side of the second slider 208. The surface of the second slider 208 is slidably connected to the inside of the chute 101. The lower end of the second slider 208 is fixedly connected to the middle part of the upper surface of the first fixing plate 207. When the action of the strength testing mechanism 3 is adjusted, the first electric telescopic rod 209 pushes the second slider 208 to also be adjusted along with the strength testing mechanism 3. The distance between the pressing device 2 and the strength testing mechanism 3 during adjustment always remains the same. The chute 101 provided on the base 1 facilitates the left and right sliding of the second slider 208.

[0034] Please refer to Figure 1, a pressing device 2 is provided on the lower surface of the base 1. The pressing device 2 includes a first fixing plate 207. The middle part of the lower surface of the first fixing plate 207 is fixedly connected to the upper end of the second movable block 210. The lower end of the second movable block 210 is fixedly connected to one end of the first spring 204. The other end of the first spring 204 is fixedly connected to the upper end of the first movable block 202. One side of the first movable block 202 is slidably connected to the middle part of the lower surface of the first fixing shell 203. The middle part of the upper surface of the first fixing shell 203 is slidably connected to one side of the second movable block 210. When the first movable block 202 and the second movable block 210 slide, the first spring 204 inside buffers the first movable block 202 and the second movable block 210, facilitating the pressing of the pressing plate 201 on the surface of the soil.

[0035] Please refer to Figure 2 , the lower end of the first movable block 202 is fixedly connected to the lower surface of the pressing plate 201. The upper surface of the pressing plate 201 is fixedly connected to one end of the second guide rod 4. The outer circumferential surface of the second guide rod 4 is sleeved inside the second spring 5. The outer circumferential surface of the second guide rod 4 is slidably connected inside the third fixing plate 308. When the third fixing plate 308 descends, the third fixing plate 308 pushes the second spring 5 to press down the pressing plate 201, facilitating the pressing of the soil surface through the pressing plate 201. The second guide rod 4 stabilizes the pressing plate 201 during downward pressing, preventing the pressing plate 201 from tilting during downward pressing.

[0036] The lower surface of the pressing plate 201 is rotatably connected to one end of the movable rod 206. The middle part of the movable rod 206 is rotatably connected to one side of the first slider 205. The lower surface of the first slider 205 is slidably connected inside the first fixing shell 203. The other end of the movable rod 206 is rotatably connected to the lower surface of the first fixing plate 207. When testing the strength of the soil crust, the third fixing plate 308 presses down the second spring 5 to press down the pressing plate 201 through the second spring 5, and the pressing plate 201 is pushed down by the first movable block 202 and the second movable block 210. When the pressing plate 201 is pressed down, it drives the movable rod 206 to move, and the first slider 205 slides inside the first fixing shell 203 through the drive, playing a limiting role.

[0037] Working principle: When conducting a mild test on soil crust, the third electric telescopic rod 306 is used to push the third fixed plate 308 downward. The third fixed plate 308 drives the detection device 309 and the cutter 311 to descend. The cutter 311 cuts the soil crust. The thrust generated during the cutting of the soil by the cutter 311 is collected by the detection device 309 to obtain the data of the soil cutting by the cutter 311. When the third fixed plate 308 descends, it squeezes the second spring 5, causing the second spring 5 to push the pressing plate 201 downward to press the surface of the soil, preventing the soil crust from sinking into the soil during the cutting of the soil crust by the cutter 311, which may result in inaccurate detection data. The second electric telescopic rod 303 is used to push the sliding plate 304 to slide inside the second fixed housing 302, which can drive the strength testing mechanism 3 to detect the soil crust in different areas. When the strength testing mechanism 3 is adjusted, the pressing device 2 also adjusts accordingly. The first electric telescopic rod 209 is used to push the second slider 208 to slide inside the internal chute 101 of the base 1, facilitating the pressing of the detection area. The first movable block 202 and the second movable block 210 squeeze the first spring 204, and the first spring 204 pushes the pressing plate 201 to press the soil. The first slider 205 slides inside the first fixed housing 203 under the action of the movable rod 206, facilitating the support of the pressing plate 201. The base 1 supports the fixed pillar 301, playing a role in support and fixation, and solving the problem that the surrounding soil of the detected soil cannot be pressed.
