[0027] like Figures 1 to 3 As shown, the utility model provides a portable electric soil extractor, including a box body 1, an electric push rod 2 is fixedly installed on the top of the box body 1, a leaf spring 3 is fixedly installed on the end of the output shaft of the electric push rod 2, a connecting column 4 is fixedly installed on the bottom end of the leaf spring 3, a connecting seat 5 is fixedly connected to the bottom end of the connecting column 4, the connecting column 4 is threadedly connected to the connecting seat 5 for easy replacement, a ring knife 6 is fixedly installed on the bottom end of the connecting seat 5, and an opening for accommodating the ring knife 6 to enter and exit is opened at the bottom end of the box body 1.

[0028] The ring cutter 6 is pushed out of the box body 1 by the electric push rod 2 so as to take soil. When taking soil is not performed, the ring cutter 6 is put into the box body 1 for easy carrying.

[0029] In this embodiment, bearing seats 7 are fixedly installed on both sides of the bottom end of the box body 1, and a threaded sleeve 8 is rotatably installed on the bearing seat 7. A screw 9 is threadedly sleeved on the inner thread of the threaded sleeve 8. The screw 9 extends downward to the outside of the box body 1. A positioning plate 10 is fixedly installed on the bottom end of the screw 9, and the positioning plate 10 is annular.

[0030] The threaded sleeve 8 rotates to make the screw 9 rise or fall, thereby driving the positioning plate 10 to rise or fall. When the positioning plate 10 falls to a certain height, the positioning plate provides stable support for the box body 1 to ensure smooth soil excavation.

[0031] In this embodiment, the threaded sleeve 8 is fixedly sleeved with a first external gear 11, the housing 1 is sleeved with an internal gear 12, the first external gear 11 is meshed with the internal gear 12, and the internal gear 12 is rotatably mounted on the side wall of the housing 1 through a mounting sleeve.

[0032] Rotating the internal gear 12 can drive the first external gear 11 to rotate, thereby driving the threaded sleeve 8 to rotate.

[0033] In this embodiment, a driving motor 13 is fixedly installed at the top end of the box body 1, and a second external gear 14 is fixedly installed on the end of the output shaft of the driving motor 13. A third external gear 15 is rotatably installed on the bottom end of the box body 1 through a rotating shaft. The second external gear 14 is meshed with the third external gear 15, and the third external gear 15 is meshed with the internal gear 12.

[0034] The driving motor 13 can drive the second outer gear 14 to rotate, the second outer gear 14 drives the third outer gear 15 to rotate, and the third outer gear 15 drives the inner gear 12 to rotate.

[0035] In this embodiment, the inner diameter of the positioning plate 10 is larger than the outer diameter of the ring cutter 6, and the ring cutter 6 moves up and down in the positioning plate 10, ensuring that the ring cutter 6 can stably descend to take soil.

[0036] In this embodiment, a conical protrusion is provided at the bottom end of the positioning plate 10. The conical protrusion is distributed in a ring shape and is divided into an outer ring and an inner ring. The conical protrusion can be inserted into the bottom surface to increase the stability of the positioning plate. The conical design reduces the disturbance of the soil.

[0037] In this embodiment, a handle is fixedly installed on the top of the box body 1 for easy carrying.

[0038] In this embodiment, a rechargeable battery may be disposed in the box 1, and a wire and a plug for connecting to an external power source may also be disposed.

[0039] When in use, move the soil sampler to a suitable position.

[0040] The driving motor 13 is started to rotate forward, so as to drive the second outer gear 14 to rotate, the second outer gear 14 drives the third outer gear 15 to rotate, and the third outer gear 15 drives the inner gear 12 to rotate.

[0041] The rotation of the internal gear 12 can drive the first external gear 11 to rotate, thereby driving the threaded sleeve 8 to rotate.

[0042] The threaded sleeve 8 rotates to make the screw rod 9 descend, thereby driving the positioning plate 10 to descend. When the positioning plate 10 descends to a certain height, the positioning plate provides stable support for the box body 1 to ensure smooth soil excavation.

[0043] The soil extractor is placed on the ground, and the conical protrusion at the bottom end of the positioning plate 10 can be inserted into the bottom surface, so that the positioning plate stably supports the box body 1.

[0044] The electric push rod 2 is started, and the electric push rod 2 pushes the ring cutter 6 out of the box body 1, and then inserts it into the soil to take soil.

[0045] After the soil is taken, lift this soil taker, carefully scrape off the redundant soil at both ends of the ring cutter 6, and wipe the soil outside the ring cutter.

[0046] Move the soil extractor to the top of the dedicated container for storing sample soil, so that the bottom end of the ring knife 6 is close to the bottom of the container. Slowly lift the soil extractor, and under the action of gravity, the soil sample in the ring knife 6 slowly slides out of the ring knife 6. When the soil sample completely leaves the ring knife 6, lift the soil extractor and close the container for storing sample soil.

[0047] Start the electric push rod 2, the electric push rod 2 shrinks, and the ring knife 6 is collected in the box body 1. Start the drive motor 13 to turn over, so that the screw rod 9 rises, and the positioning plate 10 rises to be close to the bottom surface of the box body 1, which is easy to carry.

[0048] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the essence of the utility model technology still falls within the protection scope of the technical solution of the utility model.
