[0002] As an important part of the national economy, forestry is a basic industry that focuses on forest resource cultivation and ecological protection, and has the functions of timber and forest product production and ecological protection. In forestry management practice, soil physical and chemical property analysis is a key link in evaluating soil fertility, among which the standardized collection of soil samples directly affects the accurate determination of core indicators such as pH value, organic matter content, and nutrient level.

[0003] At present, shallow soil sampling generally adopts the manual spiral sampler operation mode. The operator needs to hold the device and insert the sampling head into the soil layer by rotating and pressing down. However, the current sampler has obvious design defects: after the collection is completed, the soil sample in the sampling cavity cannot be effectively recovered by simply dumping it. It is necessary to use auxiliary tools such as scrapers to scrape deep into the sampling head. This secondary operation not only increases tool loss and pollution risks, but also has limitations such as cumbersome operation and low efficiency, which seriously restricts the convenience and timeliness of field sampling work.

[0026] A forestry soil collector comprises: a connecting rod 1, one end of the connecting rod 1 is fixedly connected to a fixed rod 2, the bottom surface of the fixed rod 2 is fixedly connected to a sampling head 4, an operating slot 11 is provided inside the fixed rod 2, a soil taking component is provided inside the operating slot 11, the soil taking component is connected to the inside of the sampling head 4, a driving component is provided inside the operating slot 11, the driving component is connected to the soil taking component, a reset component is provided inside the connecting rod 1, and the reset component is connected to the soil taking component. The soil taking component comprises: a moving rod 7, the moving rod 7 is provided inside the connecting rod 1, an inner hole 14 is provided on the inner bottom wall of the operating slot 11, the inner hole 14 is connected to the inside of the sampling head 4, one end of the moving rod 7 passes through the inner hole 14 and extends to the inside of the sampling head 4, a push block 18 is fixedly connected to the bottom surface of the moving rod 7, the push block 18 is movably connected to the inside of the sampling head 4, and a moving block 19 is fixedly connected to the top surface of the moving rod 7, and the moving block 19 is movably connected to the operating slot 11.

[0027] Specifically, the driving component includes: a plurality of connecting teeth 8, the plurality of connecting teeth 8 are all provided on one side of the moving rod 7, a gear 13 is provided inside the operating slot 11, and the gear 13 is meshed and connected with the connecting teeth 8. A fixing bar 12 is fixedly connected to the inner bottom wall of the operating slot 11, and a groove is provided on one side of the fixing bar 12, and the protruding end of the gear 13 is rotatably connected to the fixing bar 12 through the groove. The driving component also includes: a rotating rod 6, the rotating rod 6 is fixedly connected to one end of the gear 13, one end of the rotating rod 6 extends to the outside of the fixed rod 2, and the outer wall surface of the rotating rod 6 is fixedly connected to a rotating ring 5.

[0028] In this embodiment, through the rotating ring 5, the staff can continuously rotate the rotating ring 5 counterclockwise to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, it will drive the gear 13 to rotate. Since the gear 13 is rotatably connected to the fixed bar 12, the stability of the gear 13 during rotation can be ensured. The gear 13 drives the moving rod 7 to move downward through the connecting teeth 8. When the moving rod 7 moves downward, it will drive the push block 18 to slide inside the sampling head 4 until the push block 18 is completely moved to be flush with the outlet of the sampling head 4, and the soil collected inside the sampling head 4 can be pushed out by the push block 18.

[0029] Specifically, a positioning ring 3 is fixedly connected to the outer wall surface of the sampling head 4 .

[0030] In this embodiment, by setting the positioning ring 3, when the sampling head 4 completely enters the soil during soil collection, the positioning ring 3 is attached to the ground. At this time, there is no need to continue pressing the connecting rod 1 and the sampling head 4 downward, which makes it easier for the staff to determine the position of the sampling head 4.

[0031] Specifically, the reset component includes: two guide rods 10, both of which are fixedly connected to the inside of the operating groove 11, two circular holes are opened on the top surface of the moving block 19, and the moving block 19 is slidingly connected to the guide rods 10 through the circular holes, and two reset springs 9 are fixedly connected to the bottom surface of the moving block 19, and the reset spring 9 is located on the outer wall surface of the guide rod 10, and one end of the reset spring 9 is fixedly connected to the inner bottom wall of the operating groove 11.

[0032] In this embodiment, by setting the return spring 9, when the moving block 19 moves downward to squeeze the return spring 9, the return spring 9 is forced to contract. When the moving block 19 loses the downward force, the potential energy of the return spring 9 is released to drive the moving block 19 to return upward.

[0033] Specifically, an assembly groove 15 is provided inside the connecting rod 1 , a bracket 17 is movably inserted inside the assembly groove 15 , a threaded rod 16 is provided on the outer wall of the connecting rod 1 , and the connecting rod 1 and the bracket 17 are fixedly connected via the threaded rod 16 .

[0034] In this embodiment, the staff can take out the threaded rod 16 to take out the bracket 17 from the assembly groove 15, and then separate the connecting rod 1 and the bracket 17, so that the connecting rod 1 and the bracket 17 can be carried separately.

[0035] The working principle and use process of this utility model:

[0036] When in use, the staff can insert the connecting end of the bracket 17 into the assembly groove 15 and fix the bracket 17 inside the assembly groove 15 through the threaded rod 16 to achieve the effect of assembling the connecting rod 1 and the bracket 17.

[0037] Then the staff can hold both ends of the bracket 17, and align the sampling head 4 with the area where soil needs to be collected, and by pressing down the connecting rod 1 and rotating the connecting rod 1, the connecting rod 1 drives the fixing rod 2 and the sampling head 4 to rotate, so that the sampling head 4 enters the soil layer shallower than the ground to collect soil. And when the positioning ring 3 fits with the ground, it means that the sampling head 4 has completely entered the soil, and at this time, there is no need to continue pressing down the sampling head 4.

[0038] Then the staff can remove the sampling head 4 from the soil by pulling the connecting rod 1 and the sampling head 4. Then the staff can continue to rotate the rotating ring 5 counterclockwise to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, it will drive the gear 13 to rotate. Since the gear 13 is rotatably connected to the fixed bar 12, the stability of the gear 13 during rotation can be guaranteed. The gear 13 drives the moving rod 7 to move downward through the connecting tooth 8, so that the moving rod 7 drives the moving block 19 to slide downward on the outer wall surface of the guide rod 10 and squeeze the reset spring 9. At the same time, when the moving rod 7 moves downward, it will drive the push block 18 to slide downward inside the sampling head 4 until the push block 18 is completely moved to the same level as the outlet of the sampling head 4, and the soil collected inside the sampling head 4 can be pushed out by the push block 18. Then loosen the rotating ring 5, and the potential energy of the reset spring 9 is released at this time to drive the moving block 19 to reset upward, and then the moving block 19 drives the moving rod 7 and the push block 18 to reset, waiting for the next push operation.

[0039] Compared with the prior art, the present application makes it easier to remove the soil collected from the sampling head 4 after the soil is collected, without the need for a scraping tool.
