As shown in fig. 1 to 8, the present invention provides a multifunctional soil sampler, which comprises a motor 10, a rotating shaft 20, a housing 30, a push plate 40, a vacuum pump 50 and a cover plate 60.

One end of the rotating shaft 20 is connected with a power output shaft of the motor 10, and specifically, the rotating shaft 20 is connected with an output shaft of the motor 10 through a coupling 90. The other end of the shaft 20 is provided with a drill and a plurality of cutters 70. In particular, the drill bit is used to make the shaft 20 easier to insert into the soil. The cutters 70 are uniformly distributed along the axial line and the length direction of the rotating shaft 20, and the cutters 70 form a certain included angle with the cross section of the rotating shaft 20 so as to cut soil conveniently. Preferably, the cutters 70 are designed such that the length of the cutter 70 is shorter the closer to the drill bit, which facilitates the insertion of the cutter 70 and the shaft 20 into the soil.

The housing 30 is installed between the cutter 70 and the motor 10 and movably connected with the rotating shaft 20, the housing 30 is provided with a hollow inner cavity, and one side of the inner cavity facing the cutter 70 is provided with an opening.

The push plate 40 is slidably installed in the inner cavity and fixedly connected with the rotating shaft 20, and the shell 30, the rotating shaft 20 and the push plate 40 form a closed space together. Specifically, when the push plate 40 is located at the end of the cavity facing the cutter 70, the cutter 70 is located outside the cavity, and when the push plate 40 is located at the end of the cavity remote from the cutter 70, the cutter 70 and the drill bit are located within the cavity.

The vacuum pump 50 is fixedly installed at an end of the housing 30 facing the motor 10, and the vacuum pump 50 communicates with the inner cavity.

The cover plate 60 is used to cover the opening, and the cover plate 60 is detachably connected to the housing 30 by a plurality of connection structures 80.

During the use, before sampling, dismantle apron 60 for push plate 40 is located the one end of inner chamber facing cutter 70, specifically, can push pivot 20 through control casing 30 motionless, and it realizes to also can inflate to casing 30 through the air compressor machine, just so makes cutter 70 and drill bit be located outside casing 30.

During sampling, firstly, the rotating shaft 20 is inserted into soil by using external force, then the motor 10 is started, the motor 10 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the cutter 70 to rotate, so that the soil is loosened, the rotating shaft 20 is gradually inserted into the soil, and when one end of the shell 30 facing the cutter 70 is in contact with the soil or is inserted into the soil, the motor 10 is stopped. Then start the air compressor machine and make the air compressor machine take out the gas in the casing 30, will form the negative pressure like this in casing 30, under the effect of atmospheric pressure, push pedal 40 takes the one end that is provided with cutter 70 of pivot 20 to move in casing 30 to it can be internal to push soil. And finishing sampling.

Finally, the cover plate 60 is covered, the motor 10 is started again, and the cutter 70 is driven to rotate, so that the soil in the shell 30 is crushed, and the sample preparation time is shortened.

In one embodiment, the plurality of connection structures 80 are evenly distributed about the axial centerline of the housing 30. This results in a tighter and more uniform force connection between the cover plate 60 and the housing 30.

As shown in fig. 3, in one embodiment, the connection structure 80 includes a first bolt 81, a first screw hole 82 opened on an outer wall of an end of the housing 30 facing the cutter 70, and a through hole 83 opened on the cover plate 60 corresponding to the first screw hole 82.

Thus, after the cover plate 60 is closed, the first bolt 81 is inserted through the through hole 83 and then screwed into the first screw hole 82, so that the cover plate 60 is coupled to the housing 30, and when the cover plate 60 is removed, the first bolt 81 is unscrewed. The connecting structure 80 of this structure has a simple structure.

As shown in fig. 7, in one embodiment, the connection structure 80 includes a connection shaft 84, a second bolt 86, and a bayonet 87.

Wherein, the outer wall of the end of the casing 30 facing the cutter 70 is provided with a first connecting portion, the connecting shaft 84 is rotatably connected with the first connecting portion, and a second screw hole 85 is formed in the middle of the connecting shaft 84.

The second bolt 86 is threadedly coupled to the coupling shaft 84 through the second screw hole 85.

The bayonet 87 is opened on the cover plate 60 and corresponds to the second bolt 86.

Thus, when the cover plate 60 is removed, the second bolt 86 is first loosened, and then the connecting shaft 84 is rotated by the second bolt 86, so that the bolt can be taken out from the bayonet 87, and the cover plate 60 can be removed. When the cover plate 60 needs to be covered, the bayonet 87 corresponds to the second bolt 86, then the connecting shaft 84 is rotated, the second bolt 86 is clamped in the bayonet 87, and the cover plate 60 and the shell 30 can be connected by screwing the second bolt 86.

The connecting structure 80 of this structure is convenient to use, simple to connect and will not lose the bolt.

In one embodiment, the inner wall of the end of the housing 30 facing the cutter 70 is provided with a limiting portion, and one side of the push plate 40 facing the cutter 70 is provided with a limiting groove matched with the limiting portion.

When the push plate 40 moves towards the end of the housing 30 facing the cutter 70 and moves to the position of the limiting part, the push plate 40 cannot move continuously under the action of the limiting part, so that the running distance of the push plate 40 is limited. This configuration helps limit the travel distance of the push plate 40.

The working principle of the utility model is as follows:

in use, prior to sampling, the cover plate 60 is removed so that the push plate 40 is located at the end of the cavity facing the cutter 70, i.e. so that the cutter 70 and drill bit are located outside the housing 30.

The utility model provides a sample thief has sampling and kibbling dual function concurrently, has shortened the system appearance time.
