[0002] In order to study the basic physical and chemical properties of soil and provide a scientific basis for the rational utilization and improvement of soil and the treatment of soil erosion, it is necessary to sample soil according to the soil genetic horizons. The traditional method is to use manpower or a small excavator to dig a rectangular soil profile pit about 1.0 m × 1.5 m at the sampling point, and the depth of the pit should reach the parent material layer or the groundwater level. Each 10 cm from top to bottom of the entire soil profile is a soil layer, and soil samples are collected using sample bags and core samplers. This method relies on actual operation. If the sampling method is improper, it will cause the soil blocks to be incomplete and cracked, so that the water permeability of the soil cannot be tested, and complete data such as the liquid water movement characteristics cannot be obtained. The quantity collected is limited, and it is time-consuming and laborious. Therefore, a soil sampling device is proposed to solve the above problems. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Refer to Figure 1-6 , the present invention provides a soil collection device, including:

[0022] A tunneling mechanism, the tunneling mechanism includes a propulsion system 1, a soil excavation system 2, and a soil collector 3. The soil excavation system 2 includes a guide rail frame 2-3, a driver, and an excavator. The driver is fixedly connected to the guide rail frame 2-3, the excavator is movably connected to the guide rail frame 2-3, and the driver is in transmission connection with the excavator. The soil collector 3 includes a collector frame 3-1. The collector frame 3-1 is fixedly connected inside the guide rail frame 2-3. A plurality of thrusters 3-2 are fixedly connected to the collector frame 3-1, and a soil sampling assembly is fixedly connected to the output ends of the plurality of thrusters 3-2.

[0023] The propulsion system 1 is used to push the device to move into the soil. The guide rail frame 2-3 is installed at the moving end of the propulsion system 1. The propulsion system 1 drives the guide rail frame 2-3 to move into the soil. The driver drives the excavator to move, dig out the soil, so that the device can move into the soil. When the guide rail frame 2-3 enters the soil, a plurality of thrusters 3-2 on the collector frame 3-1 will push the soil sampling assembly to move, dig out the soil on the side wall of the pit, and finally bring out the dug soil.

[0024] A detection mechanism, the detection mechanism includes a temperature and humidity sensor 4, a bulk density sensor 5, a PH sensor 6, and a spectral sensor 7. The temperature and humidity sensor 4, the bulk density sensor 5, the PH sensor 6, and the spectral sensor 7 are all fixedly connected to the guide rail frame 2-3.

[0025] The temperature and humidity sensor 4 is used to measure the temperature and humidity of the soil; the bulk density sensor is used to measure physical and chemical parameters such as the water content of the soil; the pH sensor 6 is used to measure the pH value of the soil; the spectral sensor is used to take pictures of the soil cross-section and detect soil spectral data.

[0026] In a further optimized solution, the excavator includes a number of buckets 2-1. A chain 2-2 is rotatably connected between the number of buckets 2-1. The buckets 2-1 and the chain 2-2 are rotatably connected to the guide rail frame 2-3. The driver is in transmission connection with the chain 2-2 and the buckets 2-1.

[0027] The driver drives the chain 2-2 and the buckets 2-1 to rotate. When the buckets 2-1 rotate, the soil will be dug out, so that the device continuously moves deeper into the soil.

[0028] In a further optimized solution, the soil sampling assembly includes a flexible soil sampler 3-4 and two soil sampling knives 3-3. A number of thrusters 3-2 are vertically arranged on the collector frame 3-1. There are two columns of thrusters 3-2. The two soil sampling knives 3-3 are respectively fixedly connected to the output ends of the two columns of thrusters 3-2. The flexible soil sampler 3-4 is fixedly connected between the two soil sampling knives 3-3. The flexible soil sampler 3-4 bends towards the collector frame 3-1.

[0029] There are cutting edges on the two soil sampling knives 3-3. When the thrusters 3-2 drive the soil sampling knives 3-3 to extend, the soil sampling knives 3-3 will dig the soil on the side wall of the pit. As the thrusters 3-2 continuously extend, the flexible soil sampler 3-4 will bend and collect the dug soil, which is convenient for taking the soil out.

[0030] In a further optimized solution, a number of partition plates are fixedly connected inside the guide rail frame 2-3. The number of partition plates divide the guide rail frame 2-3 into a number of installation compartments. The temperature and humidity sensor 4, the bulk density sensor 5, the pH sensor 6, the spectral sensor 7 and the collector frame 3-1 are all fixedly connected inside the installation compartments.

[0031] The number of installation compartments facilitate the installation of the temperature and humidity sensor 4, the bulk density sensor 5, the pH sensor 6, the spectral sensor 7 and the collector frame 3-1, and at the same time facilitate the detection of the soil.

[0032] Usage method of this device: Place this device at the designated position, make this device contact the ground through the propulsion system 1, start the soil excavation system 2, the driver drives the chain 2-2 and the bucket 2-1 to rotate, the bucket 2-1 rotates to dig out the soil, so that this device can move deeper into the soil. When the guide rail frame 2-3 enters the soil, several thrusters 3-2 on the collector frame 3-1 will push the soil sampling knife 3-3 to move, and dig the soil on the side wall of the pit. As the thrusters 3-2 continuously extend, the flexible soil sampler 3-4 will bend, collect the excavated soil, and finally bring the soil out. The temperature and humidity sensor 4 measures the temperature and humidity of the soil; the bulk density sensor measures the physical and chemical parameters such as the water content of the soil; the PH sensor 6 measures the PH value of the soil; the spectral sensor takes pictures of the soil cross-section and detects the soil spectral data.

[0033] As Figure 6 shown, this device can be installed on an unmanned sampling device or other operating devices. The propulsion system 1 pushes the guide rail frame 2-3 to move and excavate soil underground, so that soil sampling devices such as the soil sampler 3, the temperature and humidity sensor 4, the bulk density sensor 5, the PH sensor 6, and the spectral sensor 7 can penetrate into the soil cross-section, thereby realizing the collection of the physical and chemical properties of the soil cross-section.
