DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A soil improvement sampling device comprises a base 1, a plurality of toothed inserts 2 are fixed at the bottom end of the base 1, a soil sampling tube 3 is threadedly connected to the base 1, a cavity is arranged inside the soil sampling tube 3 near the lower end, two symmetrical first rotating handles 4 are fixed on the outer wall of the soil sampling tube 3 near the top end, a soil blocking rod 5 passes through the soil sampling tube 3, a thread is arranged on the soil blocking rod 5, the soil blocking rod 5 is threadedly connected to the soil sampling tube 3, and the outer wall of the soil blocking rod 5 near the top end is provided with a cavity. Two symmetrical second rotating handles 6 are fixed on the top, and the bottom end of the soil blocking rod 5 is rotatably connected to a plurality of soil blocking blocks 7. A magnet 8 is fixed on the inner side wall of the soil blocking block 7. The soil blocking rod 5 is provided with a plurality of grooves 9 adapted to the soil blocking blocks 7. An iron sheet 10 is fixed on the groove 9. A locking groove 11 is provided in the groove 9. The bottom end of the soil blocking block 7 is slidably connected to the locking groove 11, and a stopper 12 is fixed on the outer side wall of the soil blocking block 7.

[0023] When the device is in use, first fix the base 1 on the soil surface, insert the toothed insert 2 into the soil, make the base 1 stable, in the initial state, the bottom end of the soil blocking rod 5 is located at the top of the cavity in the soil taking tube 3, the magnet 8 is fitted with the iron sheet 10, the soil blocking block 7 is located in the groove 9, hold the first rotating handle 4, rotate the soil taking tube 3, the soil taking tube 3 is threadedly connected to the base 1, so that the soil taking tube 3 is rotated downward into the soil, and the soil exists in the soil taking tube 3, hold the second rotating handle 6, rotate the soil blocking rod 5, the soil blocking rod 5 is threadedly connected to the soil taking tube 3, and the soil blocking rod 5 moves downward, and when the soil blocking block 7 moves to the specified position, the soil taking pipe 3 is rotated in the opposite direction to move the soil taking pipe 3 upward. The soil in the soil taking pipe 3 falls under the action of gravity, and the soil at the bottom contacts the stopper 12 on the soil blocking block 7, driving it to move downward, causing the soil blocking block 7 to fall off the groove 9. The soil blocking block 7 is opened, and under the restriction of the positioning groove 11, the soil blocking block 7 gives an upward force to the soil in the soil taking pipe 3, effectively preventing the soil from falling. After the soil is taken out of the ground surface, the soil blocking rod 5 is rotated again to make the soil blocking block 7 located below the bottom of the soil, so as to facilitate the removal of the soil.

[0024] It is found in actual use that the soil sampling pipe 3 is threadedly connected to the base 1, and the external thread 13 is set on the soil sampling pipe 3, which can facilitate the soil sampling pipe 3 to drill into the soil. In order to achieve the above purpose, in this embodiment, the outer wall of the soil sampling pipe 3 is set with an external thread 13, and the base 1 is provided with an internal thread adapted to the external thread 13.

[0025] It is found in actual use that the earth blocking rod 5 will be hindered by the soil when moving downward, affecting the downward movement of the earth blocking rod 5. In order to alleviate the above problem, in this embodiment, the block 12 is inclined along the thread direction of the earth blocking rod 5, and an earth blocking groove 14 is provided at the top of the block 12.

[0026] It is found in actual use that slipping is likely to occur when holding the first rotating handle 4 and the second rotating handle 6. To avoid the above problem, in this embodiment, the first rotating handle 4 and the second rotating handle 6 are both provided with an anti-slip cover 15, and the surface of the anti-slip cover 15 is provided with anti-slip patterns.

[0027] It was found in actual use that when the soil sampling tube 3 was rotated, the base 1 would shake, affecting the downward movement of the soil sampling tube 3. In order to solve the above problem, in this embodiment, two pedals 16 were provided at the bottom of the base 1, and an anti-slip protrusion 17 was provided at the top of the pedal 16.

[0028] It is found in actual use that when the soil blocking block 7 blocks the soil from falling, the removal of soil from the soil taking pipe 3 is also hindered. In order to avoid the above problem, in this embodiment, the length of the soil blocking rod 5 is set longer than the length of the soil taking pipe 3.
