[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A farmland soil testing sampler includes a base 1, a fixed handle 11 fixedly connected to the surface of the base 1, a rubber sleeve 12 fitted onto the surface of the fixed handle 11, a through groove 13 formed on the surface of the base 1, a sampling bucket 2 fixedly connected to the surface of the base 1, a slot 21 formed on the surface of the sampling bucket 2, a sliding groove 22 formed on the inner surface of the sampling bucket 2, a fixed ring 3 movably connected to the surface of the sampling bucket 2, a pedal 31 fixedly connected to the surface of the fixed ring 3, a positioning rod 32 provided on the surface of the fixed ring 3, and a locking block 33 fixedly connected to the surface of the fixed ring 3. When the sampling position is determined, the center of the fixed ring 3 is aligned with the sampling point, and the pedal 31 is stepped on to make the positioning rod 32 vertically enter the ground. The fixed ring 3 can prevent the sampling bucket 2 from shifting.

[0024] Furthermore, the rubber sleeve 12 is made of rubber. The rubber sleeve 12 is movably connected to the base 1 via the fixed handle 11. The fixed handle 11 is connected to the sampling bucket 2 via the base 1. The rubber sleeve 12 enhances the friction, making it easier to apply force during use. By pressing down on the rubber sleeve 12, the sampling bucket 2 is inserted into the ground.

[0025] Furthermore, the sampling barrel 2 is hollow inside, with two sets of slots 21 distributed on both sides of the sampling barrel 2. The sampling barrel 2 is movably connected to the slots 21 and the locking block 33. The locking block 33 is engaged in the slots 21 to connect the sampling barrel 2 and the fixing ring 3, effectively preventing the sampling barrel 2 from shifting when moving. The lower end of the sampling barrel 2 is cut into an inclined shape, making it easier to press down on the sampling barrel 2.

[0026] Furthermore, the fixed ring 3 is movably connected to the surface of the sampling bucket 2 via the locking block 33. The pedal 31 is distributed on both sides of the fixed ring 3. The pedal 31 is movably connected to the positioning rod 32 via the fixed ring 3. There are four sets of positioning rods 32, and the four sets of positioning rods 32 are evenly distributed on the surface of the fixed ring 3. The connection between the fixed ring 3 and the ground is more stable through the four sets of positioning rods 32. The surface of the pedal 31 is textured to enhance the friction.

[0027] Furthermore, a push-pull rod 4 is movably connected to the surface of the base 1. A handle 41 is fixedly connected to the upper end of the push-pull rod 4. A positioning hole 42 is opened on the surface of the push-pull rod 4. A pressure plate 43 is fixedly connected to the lower end of the push-pull rod 4. A slider 44 is fixedly connected to the surface of the pressure plate 43. A limit rod 5 is movably connected to the surface of the base 1. A threaded groove 51 is opened inside the base 1. The push-pull rod 4 is movably connected to the base 1 through the through groove 13. By adjusting the position of the push-pull rod 4 in the sampling bucket 2, the soil can be taken out, making it more convenient to use.

[0028] Furthermore, the handle 41 is movably connected to the base 1 via the push-pull rod 4, the positioning holes 42 are evenly distributed on the surface of the push-pull rod 4, the slider 44 is connected to the push-pull rod 4 via the pressure plate 43, and the push-pull rod 4 can be fixed to the position on the sampling bucket 2 via the limiting rod 5, thereby adjusting the depth of soil sampling and reducing soil pollution.

[0029] Furthermore, the limiting rod 5 is connected by threads and a threaded groove 51. The limiting rod 5 is movably connected to the inside of the base 1 through the threaded groove 51. The push-pull rod 4 is movably connected to the base 1 through the limiting rod 5. The limiting rod 5 is inserted into the inside of the base 1 through the threaded groove 51. The push-pull rod 4 and the base 1 are connected by the limiting rod 5, thereby changing the position of the pressure plate 43 in the sampling bucket 2. The limiting rod 5 facilitates the differentiation of soil at different depths.

[0030] Working principle: When using the farmland soil testing sampler, first determine the sampling point, align the center of the fixed ring 3 with the sampling point, and insert the positioning rod 32 into the ground by stepping on the pedal 31 to connect the fixed ring 3 with the ground. Press down on the fixed handle 11 to make the sampling bucket 2 take a sample. By adjusting the limit rod 5 and connecting it with different positioning holes 42, different depths of soil sampling can be obtained, making the sampling results more accurate. When the sampling bucket 2 moves downward, the fixed ring 3 is connected to the sampling bucket 2 through the locking block 33 to prevent the sampling bucket 2 from shifting.
