[0030] Example 1:

[0031] A portable soil testing device, designed for ease of use in outdoor work, such as... Figure 1-7 As shown, the device includes an auger 1 and a main cylinder 4. A motor 10 is bolted to the inner wall of the bottom of the main cylinder 4. The output end of the motor 10 is connected to a rotating rod 7 via a coupling. The auger 1 is slidably connected to the outer side wall of the rotating rod 7. A fixing mechanism is provided at the other end of the auger 1. An end component is fixedly engaged inside the fixing mechanism. A connecting ring 6 is sleeved on the outer side wall of the auger 1. A fixing box 3 is welded to the outer side wall of the main cylinder 4. A rotating plate 9 is rotatably connected to the inner wall of the fixing box 3. A bending plate 8 is rotatably connected to the inner side wall of the rotating plate 9. The other end is rotatably connected to the connecting ring 6. A rotating rod 12 is rotatably connected to the inner wall of the fixed box 3. A limiting plate 13 is connected to the outer side wall of the rotating rod 12 via a key. A torsion spring 27 is sleeved on the outer side wall of the rotating rod 12. The two ends of the torsion spring 27 abut against the outer side wall of the limiting plate 13 and the inner side wall of the fixed box 3, respectively. A lifting head 14 is glued to the outer side wall of the rotating plate 9. An abutment plate 28 is slidably connected to the inner side wall of the fixed box 3. A second spring 29 is glued between the abutment plate 28 and the bottom inner wall of the fixed box 3. The second spring 29 is in contact with the rotating plate 9.

[0032] In use, the user can directly lift the main body 4 to move the entire device. When drilling soil, place the device vertically on the ground, then turn on the motor 10 to drive the rotating rod 7 to rotate. The rotating rod 7 drives the auger 1 and the end components to rotate quickly. Then, press the limiting plate 13 to contact the lifting head 14, causing the lifting head 14 to drive the rotating plate 9 to rotate and compress the spring 29. The contact plate 28 and the rotating plate 9 retract into the fixed box 3. When the limiting plate 13 rotates to no longer limit the lifting head 14, turn the lifting head 14 out of the fixed box 3. Then, hold the lifting head 14 and rotate the rotating plate 9, causing the bending plate 8 to push the connecting ring 6 at the other end, thereby realizing the advancement of the auger 1. This achieves manual and rapid advancement, resulting in a simple and portable effect.

[0033] The end assembly includes a soil detection probe 2, a soil breaking drill bit 15, a locking plate 18, and a locking ring 19. The soil detection probe 2 and the soil breaking drill bit 15 are both welded to the bottom outer wall with connecting rods 16. The outer side wall of the connecting rod 16 is provided with a triangular groove 17. The locking ring 19 is threaded to the outer side wall of the auger 1. The locking plate 18 is rotatably connected to the inner wall of the auger 1. The locking plate 18 cooperates with the triangular groove 17.

[0034] When in use, select the soil testing probe 2 or the soil breaking drill bit 15 for installation. Rotate the locking ring 19 to squeeze the locking plate 18 and lock it into the triangular slot 17 to fix the soil testing probe 2 or the soil breaking drill bit 15. This allows for replacement as needed. The soil testing probe 2 can be inserted into the soil for testing after the soil breaking drill bit 15 has broken the soil.

[0035] The inner sidewall of the main cylinder 4 is welded with a partition plate 11, the outer sidewall of the auger 1 is provided with a triangular groove 24, the outer sidewall of the auger 1 is fitted with a plastic cover 26, the inner sidewall of the plastic cover 26 is provided with a triangular head 25, and the triangular head 25 cooperates with the triangular groove 24.

[0036] After the soil testing probe 2 or the soil breaking drill bit 15 is disassembled, it can be placed in the partition formed by the inner partition 11 of the main body 4. Then, the triangular clamp 25 on the inner wall of the plastic cover 26 is engaged with the triangular clamp slot 24 to achieve a seal, making it easy to carry.

[0037] Working principle: During use, select either the soil testing probe 2 or the soil-breaking drill bit 15 for installation. Rotate the locking ring 19 to press the locking plate 18 into the triangular slot 17, thus fixing the soil testing probe 2 or the soil-breaking drill bit 15. The user can lift the main body 4 to move the entire device. When drilling is required, place the device vertically on the ground, then turn on the motor 10 to drive the rotating rod 7 to rotate. The rotating rod 7 drives the auger 1 and end components to rotate rapidly. Then, press the limit plate 13 to contact the lifting head 14, causing the lifting head 14 to drive the rotating plate 9 to rotate and compress the spring 29. The contact plate 28 and the rotating plate 9 retract into the fixed box 3. When the limiting plate 13 rotates to no longer limit the lifting head 14, the lifting head 14 is rotated out of the fixed box 3. Then, the lifting head 14 is held and the rotating plate 9 is rotated, so that the bending plate 8 pushes the connecting ring 6 at the other end, thereby realizing the advancement of the auger 1 and realizing manual rapid advancement. After the detection work is completed, the soil detection probe 2 or the soil breaking drill bit 15 can be removed and placed in the partition formed by the partition 11 inside the main body cylinder 4. Then, the triangular clip 25 on the inner wall of the plastic cover 26 is engaged with the triangular clip groove 24 to achieve closure and facilitate carrying.

[0038] Example 2:

[0039] A portable soil testing device, such as Figure 1-7 As shown, in order to facilitate the opening and support operation, this embodiment makes the following additions based on embodiment 1: a locking ring 23 is welded to the outer side wall of the main body cylinder 4, a rotating ring 22 is rotatably connected to the outer side wall of the main body cylinder 4, a support leg 5 is rotatably connected to the outer side wall of the main body cylinder 4, the rotating ring 22 and the locking ring 23 have grooves that cooperate with the support leg 5, and a connector 21 is welded to the outer wall of the rotating ring 22 and the locking ring 23 on opposite sides, and a spring 20 is sleeved between the outer side walls of the connector 21;

[0040] Working principle: When support is required for operation, the rotating ring 22 can be rotated to disengage the locking of the support leg 5. Then, the support leg 5 can be rotated to provide support. The rotating ring 22 will then reset under the elastic force of the spring 20. When the support leg 5 needs to be stored, the rotating ring 22 can be rotated to insert the support leg 5 into the groove opened between the rotating ring 22 and the locking ring 23. Then, the rotating ring 22 will reset to limit and fix the support leg 5, making it convenient to use.
