The output end of each group of shrinking plates 38 is fixedly connected to the outer wall of the connecting arm 15. When dry soil falls into the second connecting barrel 18, in order to prevent the soil from leaking out from between the connecting arm 15 and the second connecting barrel 18, the two groups of shrinking plates 38 can be freely retracted and retracted with the movement of the connecting arm 15, which can effectively prevent the soil from leaking out. The bottom end of the inner wall of the second connecting barrel 18 is also fixedly connected to a matching block 19, and the matching block 19 is adapted to the shrinking conical arm 21;

[0039] See also Figure 8 , 10 , 11, the adding mechanism 301 includes a third connecting barrel 40, the third connecting barrel 40 is fixedly connected between the second connecting barrel 18 and the placing barrel 9, the outer wall of the third connecting barrel 40 is fixedly connected to the fixed ring 7, the outer wall of the third connecting barrel 40 is fixedly connected to a connecting rectangular tube 27, and the connecting rectangular tube 27 is slidably connected to a connecting plate 31, specifically, a sliding groove 32 is opened at the bottom end of the inner wall of the connecting rectangular tube 27, and a sliding block is fixedly connected to the bottom of the connecting plate 31, and the bottom of the sliding block is slidably connected to the inner wall of the sliding groove 32, and the inner wall of the sliding groove 32 and the outer wall of the sliding block are coated with lubricating oil, when the connecting plate 31 moves, the sliding groove 32 can limit the connecting plate 31 through the sliding block, and can also 31 has a limiting function, which improves the stability of the connecting plate 31 when it moves.

[0040] See also Fig.10The upper end of the connecting rectangular tube 27 is fixedly connected to a matching rectangular tube 34, and the front and rear ends of the matching rectangular tube 34 are fixedly connected to two groups of particle storage bins 28, and the particle storage bins 28 are filled with microbial particles.

When the pull rope 29 is pulled, the pull rope 29 will drive the sliding box 30 to move. When the sliding box 30 moves to the inside of the third connecting barrel 40, the pull rope 29 continues to pull the sliding box 30. At this time, when the sliding box 30 is pulled to the limit, the sliding box 30 will be pulled and rotated, so that the sliding box 30 can rotate to a larger tilt angle.

[0041] The working principle of the present invention is:

[0042] When in use, only dry soil needs to be placed inside the storage barrel 2, and the drive motor 37 is started at this time. The drive motor 37 pulls the transmission belt 11 through the second pulley 13, and the transmission belt 11 rotates the first pulley 12. The first pulley 12 drives all the crushing blades 36 to rotate through the transmission shaft 14. The crushing blades 36 can crush the soil into powder. When the soil becomes powder, it will enter the first connecting barrel 5;

[0043] At this time, the electric telescopic rod 3 is started, and the electric telescopic rod 3 will simultaneously drive the piston plate 6 and the connecting arm 15 to move upward, and can only move upward a little. At this time, the soil dust inside the first connecting barrel 5 will enter the inside of the conical block 16 from the inside of the matching rectangular tube 34. It is worth noting that when the connecting arm 15 drives the contraction conical arm 21 to move upward a little through the matching rod 22, the rubber ring 41 will be driven and squeezed, and when the electric telescopic rod 3 drives the contraction conical arm 21 to move downward a little through the matching rod 22, the rubber ring 41 continues to abut against the bottom of the heat connection box 17. At this time, the soil powder inside the matching rectangular tube 34 will enter the inside of the conical block 16. Since the contraction conical arm 21 is multi-stage, there is a gap between each stage, so that the soil will abut against the inner wall of the conical block 16 between each stage of the contraction conical arm 21;

[0044] At this time, the heating ring 10 is started, and the heating ring 10 will heat the liquid water inside the evaporation barrel 8. When the liquid water inside the evaporation barrel 8 is heated and boiled, the steam will enter the heat connection box 17. At this time, the temperature inside the heat connection box 17 rises, and the heat connection box 17 can perform high-temperature disinfection, heating and drying on the soil inside. When the soil is dried, heated and disinfected at high temperature, the evaporation barrel 8 drives the connecting arm 15 to move downward, and the connecting arm 15 drives the shrinking conical arm 21 to break away from the abutment with the inner wall of the conical block 16 through the matching rod 22. When the bottom of the shrinking conical arm 21 abuts against the matching block 19, the shrinking conical arm 21 is folded and contracted, and the soil adsorbed on the outer wall of the shrinking conical arm 21 will break away from the adhesion with the outer wall of the shrinking conical arm 21 and fall into the third connecting barrel 40, and then fall from the third connecting barrel 40 into the corresponding placement barrel 9;

[0045] When the evaporation barrel 8 drives the connecting arm 15 to retract downward, the connecting arm 15 will pull the pull rope 29, and the pull rope 29 will then pull the sliding box 30. Since the particle storage bin 28 is connected to the matching rectangular tube 34, the microbial particles will enter the sliding box 30 inside the matching rectangular tube 34. When the pull rope 29 pulls the sliding box 30 to move, the connecting plate 31 will move with the sliding box 30, and the sliding box 30 will block the bottom of the matching rectangular tube 34. When the sliding box 30 moves to the inside of the third connecting barrel 40, the pull rope 29 pulls and rotates the sliding box 30, so that the microbial particles inside the sliding box 30 fall into the inside of the third connecting barrel 40, and then fall from the inside of the third connecting barrel 40 into the inside of the placement barrel 9, completing the ratio of soil and microbial particles.

[0046] When the steam inside the heat connection box 17 increases, it will be discharged from the first connection pipe 26. At this time, when the steam passes through the first connection pipe 26, the liquid water inside the external pipe 25 will cool the steam inside the first connection pipe 26, thereby converting it into water. The water will then enter the water spray pipe 24 from the heat connection box 17. The water spray pipe 24 humidifies the soil inside the placement barrel 9, providing a moist environment for the microorganisms in the soil.

[0047] When the electric telescopic rod 3 is reset, the electric telescopic rod 3 will drive the matching rod 22 to reset through the connecting arm 15, and the matching rod 22 will drive the retracted conical arm 21 to reset, and the first spring 23 inside the retracted conical arm 21 will reset the retracted conical arm 21. When the electric telescopic rod 3 is reset, the piston plate 6 will be reset through the telescopic tube 4. When the electric telescopic rod 3 is reset, the connecting arm 15 will release the pulling of the pull rope 29, and at this time, the resetting elastic telescopic arm 33 will reset the connecting plate 31 and the sliding box 30. When the soil needs to be dried, it is only necessary to repeat the above operations in sequence.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
