At the same time, livestock and poultry manure is rich in nutrients such as organic matter, nitrogen, phosphorus, potassium and trace elements, and has huge utilization potential. Composting is one of the effective ways to utilize livestock and poultry resources. In the scientific research of composting, it is often necessary to analyze and test the compost materials at different stages of the composting process. The existing sampling methods are: first, use a shovel to dig the surface of the compost body, and then take out the fermentation inside the compost body. This method disturbs the compost body too much, which is not conducive to subsequent composting and sampling; second, the arm goes deep into the compost body for sampling. This method requires contact with the fermentation, which is easy to be infected with bacteria, thereby causing disease. At the same time, the temperature of the compost body usually reaches above 65°C, which is easy to burn the arm. Furthermore, the current sampling method cannot quantify the sampling volume, and the sampling volume cannot be changed according to different application scenarios.

The lower end of the reciprocating block 47 is installed in the slide groove and can slide along the slide groove. A compression spring 48 is placed in the slide groove between the lower end of the reciprocating block 47 and the piston cylinder 44.

[0032] A circular ring 51 is fixedly connected to the outer surface of the lower end of the piston cylinder 44 , a sliding block 52 is slidably connected to the circular ring 51 , a shielding plate 53 is connected above the sliding block 52 , and a control block 54 is connected to the outer side of the sliding block 52 .

[0033] A detachable protective shell 3 is installed on the support frame 1 , and the detachable protective shell 3 is located above the piston cylinder 44 .

[0034] A threaded sleeve 41 is fixedly connected to the support frame 1 and located above the detachable protective shell 3. A bidirectional screw rod 42 is threadedly connected to the threaded sleeve 41. The bottom end of the bidirectional screw rod 42 is fixedly connected to the piston 43. A cross block 7 is fixedly connected to the top end of the bidirectional screw rod 42.

[0035] A lower clamping ring 61 is fixedly connected at any horizontal position of the outer wall of the piston 43, and two spaced first through holes (not marked) are provided on the support frame 1 and below the lower clamping ring 61, and a driving block 62 is placed in each of the two first through holes. The driving block 62 includes a flat plate portion 620 at the upper end and an extension portion 621 connected to the flat plate portion 620 and extending downward, wherein the extension portion 621 can slide up and down in the first through hole, and a return spring 63 is sleeved on the extension portion 621 and located between the flat plate portion 620 and the support frame 1. A triangular plate 64 is slidably connected to the upper end of the reciprocating block 47, and a second through hole (not marked) is provided on the triangular plate 64 at a position connected to the reciprocating block 47, and the reciprocating block 47 can slide up and down in the second through hole, and a reciprocating spring 65 is sleeved on the upper end of the reciprocating block 47 and located below the triangular plate 64. An arc groove (not shown) is formed on the upper surface of the piston cylinder 44 and located on one side of the magnetic attraction block 46 . An arc plate 66 is embedded in the arc groove. The arc plate 66 is in contact with the magnetic attraction block 46 .

[0036] The utility model is a sampling device used in the composting process, and its working principle is as follows:

[0037] First, determine the relative position of the baffle 53 and the piston cylinder 44, and make sure that the piston cylinder is in a closed state. Insert the entire sampling device into the compost body of the composting device to the specified position, remove the detachable protective shell 3, and adjust the lower clamping ring 61 to the required position.

[0038] Then, the bidirectional screw rod 42 is rotated to rotate the piston 43, and because of the cooperation between the threaded sleeve 41 and the bidirectional screw rod 42, the piston 43 moves downward, and the piston 43 drives the magnetic block 46 to rotate the piston cylinder 44 and the shielding plate 53. During the rotation process, due to the stop limit of the support frame 1 on the control block 54, the shielding plate 53 is fixed, and the piston cylinder 44 continues to rotate to scrape the fermented material in the compost body and collect samples.

[0039] Next, the piston 43 moves downward while carrying the lower clamping ring 61 downward. When the lower clamping ring 61 contacts the driving block 62, the driving block 62 slides up and down in the first through hole. The U-shaped driving ring 622 formed by the outward protrusion at the lower end of the driving block 62 contacts one side of the triangular plate 64 and drives the triangular plate 64. At the same time, due to the action of the triangular plate 64, the reciprocating block 47 moves outward, and the magnetic block 46 no longer pushes the reciprocating block 47. The magnetic block 46 only drives the arc plate 66. At this time, the U-shaped driving ring 622 is just located in the notch 640 formed on the triangular plate 64, so that the arc plate 66 rotates 180° clockwise, and the piston cylinder 44 is closed, thereby meeting the quantitative requirement.

[0040] Next, the sampling device is taken out from the composting device, and the sampling device is placed on the film. The bidirectional screw rod is rotated 540° counterclockwise to open the piston cylinder 44, and the obtained sample is taken out by knocking.

[0041] Finally, the bidirectional screw rod 42 is continuously rotated counterclockwise to the end, and then the bidirectional screw rod is rotated 360° clockwise to make the magnetic block 46 contact the reciprocating block 47, and the shielding plate 53 is manually pulled to the initial position and the piston cylinder is closed, and the entire device is reset.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
