[0038] Sample tank 4 is open slot with open top, screen 2 and sample tank 4 are arranged oppositely, and sample tank 4 is used to receive sieved soil sample falling from screen 2.

[0039] Further, the first fan 61 and the second fan 62 can adopt axial flow fans, and the first fan 61 and the second fan 62 cooperate to drive the air outside to enter the containing cavity 11 from the second opening 13 and then to be discharged from the third opening 14. In this process, the flowing air flow dries the soil sample in the sample groove 4, and part of the impurities in the soil sample, such as weeds and straws, are discharged out of the containing cavity 11 together with the flowing air flow.

[0044] In some embodiments, as shown in Figure 1 The screen 2 is provided with a plurality of screens 2, the aperture of each screen 2 is different, and each screen 2 can be detachably arranged at the first opening 12 through the fixing assembly 7.

[0045] Specifically, the diameter of the screen 2 is greater than the caliber of the first opening 12, and the diameter of the screen 2 can be 15-30 cm, for example, the diameter of the screen 2 is 15 cm, 20 cm or 30 cm; the aperture of the screen 2 ranges from 8-100 mesh, for example, the screen 2 can be provided with five, and the apertures of the five screens 2 are 8 mesh, 10 mesh, 30 mesh, 60 mesh and 100 mesh in turn.

[0046] By setting each screen 2 to be detachably provided in the first opening 12, the user can replace the screen 2 with a corresponding aperture according to the particle size requirement of the soil sample. Among them, the screen 2 can be connected with the main machine 1 through a rubber pad to ensure that the screen 2 and the main machine 1 vibrate synchronously under the drive of the vibrator 3, avoiding noise caused by the vibration of the screen 2 relative to the main machine 1.

[0047] In some embodiments, as shown in Figure 1 and Figure 2 In order to facilitate the fixed installation of the screen 2, the fixing assembly 7 includes a plurality of rotating pieces 71, which are arranged circumferentially around the first opening 12, and each rotating piece 71 is rotatably provided on the top of the main machine 1 and can be switched between a first state and a second state.

[0048] When the rotating piece 71 is in the first state, the rotating piece 71 is separated from the screen 2; when the rotating piece 71 is in the second state, the rotating piece 71 is limited to the upper side of the screen 2.

[0049] It can be understood that the screen 2 includes a net body and a rim, the rim extends along the circumference of the net body, the net body is embedded in the first opening 12, and the rim is placed on the top of the main machine 1.

[0050] The rotating piece 71 includes a pressing block and a rotating shaft, the pressing block is rotatably provided on the top of the main machine 1 through the rotating shaft, and the pressing block is used to press on the upper side of the rim of the screen 2.

[0051] Before placing the screen 2, each rotating piece 71 is rotated to the first state, so that the screen 2 is placed in the area corresponding to the first opening 12; then, each rotating piece 71 is rotated to the second state, at this time each rotating piece 71 is limited to the upper side of the rim of the screen 2, and the screen 2 will not be displaced or shaken relative to the main machine 1 under the limitation of each rotating piece 71.

[0052] In some embodiments, as shown in Figure 1 The main machine 1 includes a box body 101, a box cover 102 and a flexible connection; the box body 101 is of an open-top structure, the box cover 102 is provided at the open end of the box body 101, and the flexible connection is provided between the box cover 102 and the open end; the first opening 12 is provided in the box cover 102, and the vibrator 3 is connected with the box cover 102.

[0053] It can be understood that, since the first opening 12 is arranged on the box cover 102, the screen 2 can be mounted on the box cover 102 at a region corresponding to the first opening 12.

[0054] The soft connection can be a spring or an elastic pad. Since the box cover 102 is mounted on the open end of the box body 101 through the soft connection, when the vibrator 3 is working, the vibrator 3 directly drives the box cover 102 to vibrate with a large amplitude, and then drives the screen 2 to vibrate through the box cover 102. This design can ensure the screening effect of the screen 2 on the soil sample, and the damping or buffering effect of the soft connection can avoid the generation of large vibration of the box body 101, thereby ensuring the mute effect of the main machine 1 during working.

[0055] Further, as shown in Figure 1 , in order to reduce the abnormal sound or noise generated by the main machine 1 during working, the main machine 1 further comprises a damping leg 103 arranged on the bottom end of the box body 101.

[0056] Specifically, the damping leg 103 can be a rubber foot pad, and four damping legs 103 can be arranged at the four corner portions of the bottom end of the box body 101 to support the entire device and ensure the mute effect of the vibrator 3 during working.

[0057] In some embodiments, as shown in Figure 1 , in order to ensure the efficient flow of air between the inside and outside of the main machine 1, the first fan 61 and the second fan 62 are arranged opposite to each other and located on two opposite side walls of the main machine 1.

[0058] Specifically, the arrangement height of the first fan 61 and the second fan 62 can be set to be higher than the height of the slot end of the sample groove 4. At the same time, the first fan 61 can be arranged on the left side wall of the main machine 1, and the second fan 62 can be arranged on the right side wall of the main machine 1. The arrangement height of the first fan 61 and the arrangement height of the second fan 62 can be the same or different, and no specific limitation is made to this.

[0059] Optionally, the central axis of the first fan 61 is arranged to be inclined relative to the horizontal plane, so that the air outlet side of the first fan 61 faces the sample groove 4. This design ensures that the first fan 61 drives the air outside to directly blow into the sample groove 4, thereby enhancing the air-drying effect on the soil sample in the sample groove 4.

[0060] Optionally, the central axis of the second fan 62 is arranged to be inclined relative to the horizontal plane, so that the air inlet side of the second fan 62 faces the sample groove 4. This design facilitates the formation of a negative pressure interval between the sample groove 4 and the second fan 62, which not only realizes the exhaust of the main machine 1, but also ensures that part of the impurities in the soil sample, such as weeds and straws, are discharged out of the containing cavity 11 together with the flowing air.

[0061] Optionally, the central axis of the first fan 61 is arranged to be inclined relative to the horizontal plane, so that the air outlet side of the first fan 61 faces the sample groove 4; the central axis of the second fan 62 is arranged to be inclined relative to the horizontal plane, so that the air inlet side of the second fan 62 faces the sample groove 4; such a design ensures that the first fan 61 and the second fan 62 can cooperate with each other, not only ensuring the air-drying effect on the soil sample in the sample groove 4, but also facilitating the use of the flowing air flow to carry away part of the impurities in the soil sample with lighter mass, thereby realizing the impurity removal treatment of the soil sample.

[0062] In some embodiments, as shown in Figure 1 The soil sample rapid processing device further comprises a heating member 5 arranged on the first fan 61 to heat the air delivered by the first fan 61 into the main machine 1.

[0063] Specifically, the heating member 5 can be an electric heating sheet or an electric heating wire, and the heating member 5 is arranged on the air inlet side of the first fan 61.

[0064] For example, the heating member 5 is an electric heating sheet, a plurality of hollow openings are arranged on the electric heating sheet, the plurality of hollow openings are arranged in an array, and the electric heating sheet is provided with a mounting hole, and the electric heating sheet is mounted on the air inlet side or the air outlet side of the first fan 61 through the mounting hole.

[0065] In actual application, when the heating member 5, the first fan 61 and the second fan 62 are started and operated, the air delivered by the first fan 61 into the main machine 1 is heated by the heating member 5, so that the first fan 61 can directly deliver hot air to the soil sample in the sample groove 4, and the second fan 62 can simultaneously discharge the air in the main machine 1, thereby ensuring that the hot air continuously flows through the soil sample and exchanges heat with the soil sample by convection, so as to realize the rapid drying treatment of the soil sample.

[0066] In some embodiments, the soil sample rapid processing device further comprises a heating member 5 arranged in the containing cavity 11 and located on one side of the sample groove 4 to heat the air flowing through the sample groove 4 in the containing cavity 11.

[0067] Specifically, the heating member 5 can be arranged around the sample groove 4, so that when the first fan 61 and the second fan 62 are started and operated, the heating member 5 can heat the air flowing through the sample groove 4 in the main machine 1, and the same effect of rapidly drying the soil sample can be achieved.

[0068] In some embodiments, the main machine 1 further has a fourth opening in communication with the containing cavity 11, and the sample groove 4 is configured to be inserted into the containing cavity 11 through the fourth opening.

[0069] It can be understood that the fourth opening can be arranged on the front side wall or the rear side wall of the main machine 1, and the sample groove 4 can be pushed into the accommodating cavity 11 through the fourth opening to contain the soil sample sieved from the sieve 2. The sample groove 4 can also be pulled out of the accommodating cavity 11 through the fourth opening to transfer the soil sample collected in the sample groove 4 to a detection station. Near-infrared spectrum detection device can be used at the detection station to detect the content of organic matter in the soil sample.

[0070] The fourth opening can be arranged close to the bottom end of the main machine 1. After the sample groove 4 is taken out of the main machine 1, the impurities remaining in the main machine 1 can be poured out through the fourth opening.

[0071] Based on the scheme shown in the above embodiment, the following steps can be used for pretreatment of the soil sample. The specific steps are as follows:

[0072] Step one: collect the original soil sample, remove the obvious impurities such as large-sized stone seeds and animal and plant residues in the obtained original soil sample in advance, and break the large soil blocks into small blocks;

[0073] Step two: according to the particle size requirement of the required soil sample, a sieve with a corresponding aperture is installed at the first opening, and the sieve is fixed by using a fixing assembly;

[0074] Step three: evenly spread the treated soil sample on the sieve, start the vibrator, and observe the passing condition of the soil sample through the sieve;

[0075] Step four: if the soil sample can pass through the sieve smoothly and there is no obvious agglomeration, the following steps are executed:

[0076] Start the heating member, the first fan and the second fan, and control the three to work cooperatively with the vibrator;

[0077] After the sieving of the soil sample is completed, stop the vibrator, the heating member, the first fan and the second fan, pull out the sample groove from the main machine, and observe whether the water content of the soil sample in the sample groove meets the use requirement. If the water content of the soil sample meets the requirement, the sieved soil sample is poured out for use. If the water content of the soil sample cannot meet the requirement, the remaining impurities in the sieve are removed, and the vibrator, the heating member, the first fan and the second fan are controlled to start simultaneously. While the main machine is vibrated by the vibrator, the sieved soil sample is heated by using hot air to achieve the purpose of rapid air drying of the sieved soil sample.

[0078] Step five: if the vibrated soil sample is agglomerated and cannot pass through the sieve directly, the following steps are executed:

[0079] The vibrator is turned off, the minimum aperture screen is replaced, the soil sample is placed on the screen, the heating element and the first fan are controlled to start running, the second fan is controlled to stop running, and the soil sample on the screen is air-dried;

[0080] Then, the vibrator and the second fan are controlled to start running, the sieved soil sample is heated, and the sieved soil sample collected in the sample tank is heated until the soil sample placed on the screen is sieved.

[0081] In summary, the soil sample rapid processing device can automatically and quickly pretreat the original soil sample according to sample requirements on the soil sampling site, significantly saves labor cost, and improves sample processing efficiency, especially for the application of soil on-site detection technology, and provides a miniaturized automatic soil pretreatment equipment.
