Description

Technical Field

[0001] The present application relates to a soil sampler. Background Art

[0002] Soil is a natural body formed by the interaction of factors such as parent material, climate, biology, topography and time. In different natural environments, the formation process and properties of soil are unique. Soil is a component of the biosphere on the earth's surface. It provides nutrition and water for terrestrial plants and is an important place for plants to carry out photosynthesis and energy exchange. Therefore, soil quality is one of the important indicators of environmental evaluation. Soil samplers can be used to collect soil samples, which is convenient for people to accurately and effectively evaluate the soil environment.

[0003] Generally, the soil sampling location is uneven, and the common sampler has a fixed structure, which makes it inconvenient to level the sampler according to the ground conditions, which will cause the sampler to be tilted and unstable. Moreover, when sampling the soil, it is necessary to sample soil at different depths. It is inconvenient to limit the sampler during sampling, and the sampling depth cannot be accurately determined, which will affect the accuracy of soil environmental evaluation.

[0004] Therefore, it is desirable to provide a soil sampler. Utility Model Content

[0006] According to one aspect of the present application, a soil sampler is provided, comprising a top plate, on which a sampling structure is arranged, characterized in that the soil sampler further comprises:

[0007] A limit plate, wherein the limit plate is arranged at the bottom of the top plate, an adjusting rod is fixed to one end of the top of the limit plate, and the adjusting rod is fixed to the top plate by a fixing structure;

[0008] The threaded rod and the roller are arranged at two ends of the limiting plate.

[0009] Specifically, the sampling structure includes a motor, a spiral blade, a collecting chamber and a scraper. The motor is fixed in the middle of the top of the top plate. A spiral blade is fixed on the output end of the motor through the top plate. A collecting chamber is provided in the spiral blade, and a scraper is clamped in the collecting chamber.

[0010] Specifically, a handle is fixed in the middle of the two side walls of the top plate, a battery is fixed in the top, a control switch is fixed at one end of the side wall of the top plate, and the battery and the control switch are connected to the motor through a wire.

[0011] Specifically, the spiral blade passes through the limiting plate, and two ends of the top of the limiting plate are threadedly connected with multiple groups of threaded rods, and the threaded rods pass through the limiting plate and are fixed with rollers.

[0012] In this technical solution, when the ground is uneven, the height of the roller can be adjusted by rotating the threaded rod so that the limit plate is in a horizontal position, which can make the sampler stable and not easy to tip over, thereby improving the practical performance of the sampler.

[0013] Specifically, the fixed structure comprises a fixing plate, a limiting rod, a spring, a mounting plate, a clamping block, a connecting plate and a pulling plate. The fixing plate is fixed to one end of the bottom of the top plate close to the adjusting rod, and the top end of the adjusting rod passes through the top plate and extends to the outside.

[0015] Specifically, connecting plates are fixed to the side walls of the mounting plate on both sides of the limiting rod, and the other end of the connecting plate passes through the fixing plate and is fixed to the pulling plate.

[0016] In this technical solution, when sampling, the adjustment rod is moved up and down, the height of the limit plate is adjusted according to the sampling depth, and then the adjustment rod is fixed by a fixing structure so that the spiral blade can be accurately inserted into the sampling depth.

[0017] The benefits of this application are:

[0018] 1. By setting threaded rods and rollers at both ends of the limit plate, when the ground is uneven, the height of the roller can be adjusted by rotating the threaded rod to make the limit plate in a horizontal position, so that the sampler can be placed stably and not easily tipped over, thereby improving the practical performance of the sampler.

[0019] 2. By setting a limit plate and an adjusting rod on the top of the limit plate, when sampling, move the adjusting rod up and down, adjust the height of the limit plate according to the sampling depth, and then fix the adjusting rod through a fixed structure so that the spiral blade can be accurately inserted into the sampling depth to avoid affecting the accuracy of soil environmental evaluation.

[0031] See also Figure 1-3 As shown, a soil sampler comprises a top plate 1, on which a sampling structure 2 is arranged, and characterized in that the soil sampler further comprises:

[0032] A limit plate 3, wherein the limit plate 3 is arranged at the bottom of the top plate 1, an adjusting rod 4 is fixed to one end of the top of the limit plate 3, and the adjusting rod 4 is fixed to the top plate 1 by a fixing structure 5;

[0033] The threaded rod 6 and the roller 7 are arranged at two ends of the limiting plate 3 .

[0034] The sampling structure 2 includes a motor 201, a spiral blade 202, a collection chamber 203 and a scraper 204. The motor 201 is fixed in the middle of the top of the top plate 1. The output end of the motor 201 passes through the top plate 1 and is fixed with a spiral blade 202. The spiral blade 202 is provided with a collection chamber 203, and the scraper 204 is clamped in the collection chamber 203.

[0035] A handle 8 is fixed in the middle of the two side walls of the top plate 1, a battery 10 is fixed in the top, a control switch 9 is fixed at one end of the side wall of the top plate 1, and the battery 10 and the control switch 9 are connected to the motor 201 through wires.

[0036] The spiral blade 202 passes through the limiting plate 3 , and two ends of the top of the limiting plate 3 are threadedly connected with multiple groups of threaded rods 6 , and the threaded rods 6 pass through the limiting plate 3 and are fixed with rollers 7 .

[0037] When the ground is uneven, the height of the roller 7 can be adjusted by rotating the threaded rod 6 so that the limit plate 3 is in a horizontal position, which can make the sampler stable and not easy to tip over, thereby improving the practical performance of the sampler.

[0038] The fixing structure 5 includes a fixing plate 501, a limiting rod 502, a spring 503, a mounting plate 504, a clamping block 505, a connecting plate 506 and a pulling plate 507. The fixing plate 501 is fixed to one end of the bottom of the top plate 1 close to the adjusting rod 4, and the top end of the adjusting rod 4 passes through the top plate 1 and extends to the outside.

[0039] The fixing plate 501 is inserted into the middle of the side wall of the adjusting rod 4 to fix a limiting rod 502 and a spring 503, and the spring 503 is sleeved on the outside of the limiting rod 502. The other end of the limiting rod 502 and the spring 503 is fixed with a mounting plate 504, and the other side wall of the mounting plate 504 is fixed with a clamping block 505.

[0042] When the present application is in use, first, the sampler is moved to the designated position. When the ground is uneven, the height of the roller 7 is adjusted by rotating the threaded rod 6 so that the limit plate 3 is in a horizontal position, so that the sampler remains stable and is not easy to tip over. When sampling, the pull plate 507 is pulled outward to pull the block 505 out of the slot 11, and the adjusting rod 4 is moved up and down. The height of the limit plate 3 is adjusted according to the sampling depth to determine the depth of the spiral blade 202 inserted into the ground, and then the pull plate 507 is released. The block 505 rebounds under the action of the spring 503 and is stuck in the corresponding slot 11, thereby fixing the adjusting rod 4, placing the spiral blade 202 on the sampling ground, and starting the motor 201 by controlling the switch 9. The motor 201 drives the spiral blade to rotate so that the spiral blade 202 is inserted into the ground, and the soil will be collected in the collecting chamber 203.
