Compared with the prior art, the soil sampling device based on new energy power supply provided by the embodiment has the advantages that the solar cell panel 102 converts light energy into electric energy and transmits the stored electric energy to the driving motor 101. The driving motor 101 drives the drill 4 and the sampling tube 2 to rotate around the axis through the rotating shaft 3. Since the drill 4 has the same outer diameter as the sampling cylinder 2, the drill 4 can drill a sampling hole that exactly matches the sampling cylinder 2. Be equipped with a plurality of soil collection chambeies 201 on the sampling tube 2, a plurality of soil collection chambeies 201 top-down sets up to all install scraper blade subassembly 5 and elasticity piece 6 that resets in every soil collection chamber 201. The scraper blade assembly 5 and the elastic return member 6 rotate synchronously with the sampling cylinder 2.

In this embodiment, the suction fan 104 is fixedly mounted on the support frame 1. The drill 4 is located at a vertical distance from the sampling cylinder 2, so that a soil transfer chamber 202 is formed. Soil transfer channel 301 is maintained parallel to the axial direction of rotating shaft 3 and extends throughout rotating shaft 3. The output shaft of the driving motor 101 and the drill bit 4 are both connected with the rotating shaft 3 through threads, and the output shaft of the driving motor 101 and the drill bit 4 respectively plug the openings at the upper end and the lower end of the soil transmission channel 301. The air outlet and the air inlet are respectively positioned at the upper end and the lower end of the rotating shaft 3 and are respectively arranged along the radial direction of the rotating shaft 3. An air pipe 108 connected with the exhaust fan 104 is arranged at the air outlet, and the air inlet is communicated with the soil conveying cavity 202 and the soil conveying channel 301.
The drill bit 4 is driven by the driving motor 101 to perform a drilling operation at a sampling point, and the drill bit 4 transfers soil below the drill bit 4 upwards into the soil transfer cavity 202.

In this embodiment, the connecting seat 105 is circular and is fixedly mounted on the bottom surface of the supporting frame 1 by screws or other fasteners. The connecting base 105 is located directly above the sampling tube 2. The inner hole of the connecting seat 105 is matched with the rotating shaft 3, and the rotating shaft 3 is in sliding fit with the side wall of the inner hole of the connecting seat 105. The annular groove 106 is located in the middle of the connecting seat 105 in the vertical direction, and the number of the air outlet holes can be one or more. One end of the air outlet is communicated with the soil transmission channel 301, and the other end of the air outlet is communicated with the annular cavity. In the sampling process, the rotating shaft 3 rotates relative to the connecting seat 105, but the air outlet hole is always communicated with the annular groove 106, so that the soil in the soil transmission channel 301 is ensured to be continuously transmitted into the air pipe 108.
It is necessary to ensure good sealing between the coupling seat 105 and the rotary shaft 3 so as to prevent air leakage in the annular groove 106. In order to improve the sealing between the coupling seat 105 and the rotary shaft 3, a rubber-made packing may be installed between the coupling seat 105 and the rotary shaft 3. The exhaust fan 104 is installed on the outer side wall of the support frame 1, and the support frame 1 is correspondingly provided with a yielding hole for the air pipe 108 to pass through.
In some embodiments, referring to fig. 1, the top surface of the drill 4 is a conical surface.
In this embodiment, the top surface of the drill 4 is a conical surface, i.e., the top of the drill 4 is a pointed end. The cross-section of the soil transfer chamber 202 increases gradually in a direction away from the rotation shaft 3. After the drill bit 4 upwards transmitted soil to the soil transmission cavity 202, soil can move towards one side of keeping away from the axis of rotation 3 along the circular cone under the action of self gravity, and soil can present the state of rolling in the soil transmission cavity 202 promptly to effectively avoid soil to produce in the soil transmission cavity 202 and store up.
In some embodiments, referring to fig. 1 and 5, the rotating shaft 3 is provided with a ratchet 304, and the sampling tube 2 is provided with a pawl 203 corresponding to the ratchet 304.

Now, the description will be given by way of example: after the sampling work begins, driving motor 101 drives drill bit 4 through axis of rotation 3 and carries out corotation (perhaps reversal), and sampling tube 2 keeps static for support frame 1 this moment, and scraping plate subassembly 5 can not take place relative displacement for sampling tube 2, and sampling tube 2 can be along with this soil sampling device whole downstream and enter into in the sample hole. When this soil sampling device descends to appointed degree of depth, driving motor 101 antiport, it drives sampler barrel 2 pivoting to rely on ratchet 304 and pawl 203 at axis of rotation 3, sampler barrel 2 can drive scraper assembly 5 synchronous rotation, along with sampler barrel 2 slew rate's gradual increase, scraper assembly 5's centrifugal force is along with the increase, when scraper assembly 5's centrifugal force is greater than the elasticity of elasticity piece 6 that resets, scraper assembly 5 can be along the radial outside lateral shifting of axis of rotation 3 (or sampler barrel 2), then carry out the scraper operation to the soil layer that corresponds the degree of depth. The soil sampling amount of the scraper bar assembly 5 is in direct proportion to the distance that the scraper bar assembly 5 moves to the outside, the distance that the scraper bar assembly 5 moves to the outside is in direct proportion to the centrifugal force of the scraper bar assembly 5, and the centrifugal force of the scraper bar assembly 5 is in direct proportion to the rotation rate of the scraper bar assembly 5 (the sampling cylinder 2), so the soil sampling amount of the scraper bar assembly 5 can be adjusted by controlling the rotation rate of the sampling cylinder 2. After the soil sampling operation is completed, the driving motor 101 is firstly closed, the rotating speed of the sampling cylinder 2 is gradually reduced until the sampling cylinder stops, the elastic resetting piece 6 enables the soil scraping plate component 5 to move towards the inside of the soil collecting cavity 201 by means of the elasticity of the elastic resetting piece and completely enter the soil collecting cavity 201, and at the moment, the soil sampling device can be smoothly taken out from the sampling hole.
