[0002] Microbial fertilizers, also known as biofertilizers, inoculants, or bacterial fertilizers, refer to a type of fertilizer product that uses the life activities of microorganisms to achieve specific fertilizer effects on crops. There is a fundamental difference between microbial fertilizers and trace elements: the former are living organisms, while the latter are mineral elements. Microbial resources are abundant, with a wide variety of types and functions, and can be developed into fertilizers with different functions and uses. Furthermore, microbial strains can be artificially selected, purified, and rejuvenated to enhance their vitality. With the further development of biotechnology, it has become possible to obtain desired strains through genetic engineering methods. Therefore, microbial fertilizer processing requires sampling.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides a technical solution:

[0027] Example 1, combined with Figures 1 to 4 A sampling device for microbial fertilizer production includes a sampling cannula 3, a handle 31 is fixedly connected to the top of the rear side of the sampling cannula 3, a sampling mechanism 1 is arranged in the sampling cannula 3, and a fixing mechanism 2 is arranged on the front side of the sampling mechanism 1 above the sampling cannula 3.

[0028] The sampling mechanism 1 includes an insertion component 11, a telescopic component 12 and a push-pull component 13. The insertion component 11 is arranged at the bottom of the sampling cannula 3, the telescopic component 12 is arranged at the top of the insertion component 11, and the push-pull component 13 is arranged at the top of the telescopic component 12.

[0029] The insertion component 11 includes a slide 1101, which is slidably connected to the inner ring of the sampling cannula 3. The bottom of the slide 1101 is fixedly connected to a rounded cone head 1102. The outer ring of the slide 1101 is fixedly connected to a limit slider 1103. The limit slider 1103 is slidably connected to the inner ring of the sampling cannula 3. The telescopic component 12 includes a special-shaped telescopic rod 1201, which is fixedly connected to the top of the slide 1101. The outer ring of the special-shaped telescopic rod 1201 is slidably connected to a special-shaped sleeve 1202. The special-shaped sleeve 1202 is fixedly connected to the top of the sampling cannula 3. The push-pull component 13 includes a fixed frame 1301, which is fixedly connected to the top of the special-shaped telescopic rod 1201. The push-pull rod 1302 is fixedly connected inside the fixed frame 1301.

[0030] Furthermore, the work only requires moving the slide 1101 to the lowest position in the sampling cannula 3 and fixing it, and then the sampling cannula 3 can be driven to be inserted into the waste pile through the limit slider 1103, so that the staff can release the fixation of the special-shaped telescopic rod 1201 after the sampling cannula 3 is inserted into the predetermined depth, and then pull the special-shaped telescopic rod 1201 to complete the sampling of the fertilizer, so that the staff can adjust the sampling depth and sampling quantity. At the same time, the device only requires the hands of the staff to complete all controls, so that the device can follow the operator's hand angle to change and perform complex angle sampling of the fertilizer pile when in use. The operation is simple and convenient for the staff to use.

[0031] Example 2, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , and on the basis of Example 1, it is further obtained that the fixing mechanism 2 includes a positioning component 21, a limiting component 22 and an adjusting component 23, the positioning component 21 is arranged on the front side of the telescopic component 12, the limiting component 22 is arranged inside the front side of the positioning component 21, and the adjusting component 23 is arranged on the inner circle of the limiting component 22.

[0032] The positioning assembly 21 includes a fixed cylinder 2101, which is fixedly connected to the front side of the special-shaped sleeve 1202. A soft positioning block 2102 is slidably connected inside the fixed cylinder 2101. The rear side of the soft positioning block 2102 fits in the front side of the special-shaped telescopic rod 1201. The limiting assembly 22 includes a sliding rod 2201, which is fixedly connected to the front side of the soft positioning block 2102. The sliding rod 2201 is slidably connected inside the front side of the fixed cylinder 2101. The front side of the sliding rod 2201 is fixedly connected to the limit ring 2202, and the adjustment component 23 includes a threaded rod 2301, the threaded rod 2301 is rotatably connected to the front side of the soft positioning block 2102, the threaded rod 2301 is threadedly connected to the front side of the fixed cylinder 2101, the front side of the threaded rod 2301 is fixedly connected to the protrusion 2302, the outer ring of the protrusion 2302 is fixedly connected to the connecting arm 2303, and the outer side of the connecting arm 2303 is fixedly connected to the torsion disk 2304.

[0033] Furthermore, the staff only needs to rotate the torsion plate 2304 to drive the soft positioning block 2102 to move back and forth to fix or release the special-shaped telescopic rod 1201. The operation is simple and convenient for the staff to use.

[0034] In actual operation, when this device is used, when it is necessary to sample fertilizer at a specific depth, the staff first pushes the push-pull rod 1302 to drive the slide 1101 to move to the bottom of the sampling cannula 3, and then the staff rotates the torsion plate 2304. The rotation of the torsion plate 2304 drives the threaded rod 2301 to rotate through the connecting arm 2303 and the protrusion 2302. The threaded rod 2301 rotates inside the front side of the fixed cylinder 2101 and moves backward. The fixed cylinder 2101 moves backward and contacts the front side of the special-shaped telescopic rod 1201 until the torsion plate 2304 can no longer rotate. At this time, the fixing process of the special-shaped telescopic rod 1201 is completed, and then the staff inserts the sampling cannula 3 into the fertilizer. In the material pile, after the rounded cone head 1102 moves to the predetermined depth, the staff rotates the torsion disk 2304 again. It can be seen from the above that the rotation of the torsion disk 2304 drives the fixed cylinder 2101 to move. At this time, the fixed cylinder 2101 moves forward to release the positioning of the special-shaped telescopic rod 1201. Then the staff holds the handle 31 to keep the position of the sampling cannula 3 unchanged, and pulls the push-pull rod 1302 outward. The movement of the push-pull rod 1302 drives the slide 1101 to move outward and retract into the sampling cannula 3. While the slide 1101 moves outward, the hand on the other side gradually pushes the sampling cannula 3 inward, so that the fertilizer at the predetermined depth can enter the sampling cannula 3, and the sampling process of the fertilizer at a specific depth is completed.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
