Description

Technical Field

[0001] The utility model belongs to the technical field of forestry, and in particular relates to a soil sampler for forestry. Background Art

[0002] A soil sampler is a tool used to obtain soil samples. Commonly used tools include soil augers, shovels, and spades. A soil auger consists of a drill bit and a handle made of hard material. The drill bit is usually spiral or cylindrical. The top of the spiral drill bit features a pair of sharp blades that rotate and cut into the soil. Immediately following the blades is an enlarged cavity for collecting soil. As the handle rotates, the drill bit drills down into the soil surface, introducing the soil sample from the desired layer into the cavity. The diameter of a cylindrical soil auger is slightly different at each end. The end connected to the handle is slightly larger than the end that contacts the soil. This ensures that soil already inside the cylinder will not be scattered due to the movement of the auger. The handle of the auger is engraved with a scale to control the sampling depth.

[0003] Once the auger is lifted from the soil surface, soil samples can be taken. Soil samples can be collected at different depths in the original sampling hole. However, care should be taken to prevent soil debris around the sampling hole from flowing into the hole when the auger is removed. Soil auger sampling is minimally destructive to the soil and allows for layered sampling. Spades are often used to dig profile pits for collecting profile samples or whole-section specimens. Existing soil samplers are not convenient to use. During sampling, workers apply pressure with their hands or feet to penetrate the soil surface. This pressure can easily cause the sampler to shift, affecting the integrity of the soil sample. Utility Model Content

[0019] 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.

[0020] Example

[0021] See also Figure 1-3 The utility model provides the following technical solutions: a soil sampler for forestry, comprising a positioning mechanism 1 and a sampling mechanism 2:

[0022] The positioning mechanism 1 includes a positioning cylinder 101 and a positioning plate 102. The side surface of the positioning cylinder 101 and the upper surface of the positioning plate 102 are respectively provided with two fixing blocks 103 and a positioning block. The positioning block is hinged with a connecting block 104 inside. The connecting block 104 below the side of the positioning cylinder 101 is fixedly connected to the side of the positioning plate 102. The connecting block 104 above the side of the positioning cylinder 101 and the opposite surface of the connecting block 104 above the positioning plate 102 are respectively fixedly provided with a connecting plate 105. The positioning block and the connecting block 104 are hingedly connected to facilitate adjustment of the angle of the positioning cylinder 101 and the positioning plate 102.

[0023] A bearing 106 is embedded in the upper surface of the lower connecting plate 105. A rotating shaft 107 is provided in the bearing 106. The top end of the rotating shaft 107 is fixedly connected to the bottom end of the threaded cylinder 108. A threaded column 109 is rotatably provided in the threaded cylinder 108. The top end of the threaded column 109 is fixedly connected to the lower surface of the upper connecting plate 105. The arrangement of the bearing 106 and the rotating shaft 107 allows the threaded column 109 to rotate stably. The angle of the positioning cylinder 101 and the positioning plate 102 can be adjusted by rotating the threaded cylinder 108 on the surface of the threaded column 109.

[0024] The sampling mechanism 2 includes a sampling barrel 201, in which a push plate 202 is slidingly arranged. The upper surface of the push plate 202 is fixedly connected to the bottom end of the slide rod 203. The bottom end of the slide rod 203 passes through the through hole opened on the surface of the sampling barrel 201 and is fixedly connected to the lower surface of the circular plate 204. The bottom end of the sampling barrel 201 is set at an acute angle, which is convenient for inserting into the soil surface for sampling. When sampling, the circular plate 204 is used to drive the push plate 202 to move through the slide rod 203 to ensure the integrity of the soil sample.

[0025] Specifically, a knob 110 is provided on the surface of the threaded barrel 108, and anti-slip grooves are provided on the surface of the knob 110. When adjusting the angle between the positioning barrel 101 and the positioning plate 102, the knob 110 can be turned to rotate the threaded barrel 108, and the relative position of the threaded barrel 108 and the threaded column 109 can be adjusted.

[0026] Specifically, the upper surface and lower surface of the positioning plate 102 are respectively provided with an anti-slip pad 111 and a grounding nail 112. The positioning plate 102 contacts the soil surface through the grounding nail 112, which can prevent the positioning plate 102 from shifting and affecting the sampling work. The anti-slip pad 111 increases the friction when the foot steps on the positioning plate 102, and can stably fix the positioning tube 101.

[0027] Specifically, handles 205 are provided on the surface of the sampling cylinder 201 . The handles 205 are provided on both sides of the sampling cylinder 201 , so that the staff can apply pressure to the sampling cylinder 201 through the handles 205 .

[0028] The working principle of this utility model is:

[0029] When in use, the staff first uses tools such as shovels to clean up the debris and surface at the sampling position, and adjusts the angle between the positioning tube 101 and the positioning plate 102 according to the slope of the soil surface and the position where the sampling is desired. When adjusting the angle, the staff turns the knob 110 to rotate the threaded tube 108, which can move the threaded column 109 into the threaded tube 108 to complete the adjustment of the angle of the positioning tube 101 and the positioning plate 102. The positioning plate 102 contacts the soil surface through the grounding nail 112. The staff inserts the sampling tube 201 into the positioning tube 101, steps on the positioning plate 102 with the foot, and applies pressure to the sampling tube 201 through the handle 205 to facilitate sampling through the sampling tube 201. After the sampling is completed, the staff can push the circular plate 204 to make the slide rod 203 push the push plate 202 to push the soil sample out of the sampling tube 201.
