Referring to fig. 1-5, a sampling device comprises a main body rod 11, an earth taking drill bit 12, a grip 13, a dozer rod 21 and a dozer piece 22. Wherein main part pole 11 and the drill bit 12 of fetching earth are hollow structure, the lower extreme at main part pole 11 is connected to drill bit 12 of fetching earth, and for the equipment convenience when carrying and field usage, both adopt threaded connection's mode fixed connection. In addition, according to different sampling depths of matching, the main body rod 11 can be a single rod, and can also be provided with a plurality of short rods and spliced into the main body rod 11. The grips 13 are connected to both sides of the upper end of the main body rod 11 for the user's operation. The dozing rod 21 is sleeved in the main body rod 11, the length of the dozing rod 21 is longer than that of the main body rod 11, the upper end of the dozing rod passes through the upper end of the main body rod 11, in order to take out a soil sample after sampling is completed, a disc-shaped structure 23 is arranged at the top end of the dozing rod 21, the dozing part 22 is located in the soil taking drill bit 12 and connected with the lower end of the dozing rod 21, and in order to facilitate assembly, a threaded connection mode is preferably adopted for the dozing rod 21 and the dozing rod.

Specifically, before use, the sampling device is assembled, the main body rod 11 and the soil sampling drill bit 12 are fixedly connected, the soil pushing rod 21 is inserted into the main body rod 11, the lower end of the soil pushing rod 21 penetrates out of the lower end of the drill bit, and the soil pushing part 22 and the lower end of the soil pushing rod 21 are fixedly connected. The dozer 22 is pushed into the dozing bit 12 so that the upper end of the dozer rod 21 passes through the upper end of the main body rod 11, and the dish structure 23 is fixedly attached to the upper end of the dozer rod 21, thereby completing the assembly.

The main improvement of the present application to the sampling device is that the collar 31 is movably sleeved outside the main body rod 11, and the main body rod 11 can axially move relative to the collar 31 and rotate around its axis, that is, the collar 31 does not interfere with the main body rod 11 to auger into the soil surface. Two pedal structures are connected to the collar 31 and supported on the ground for the user to step on with his foot when sampling. When a user holds the grip 13 with two hands to auger the main body rod 11 and the soil sampling drill bit 12 into the soil surface, the axial deviation of the main body rod 11 is easily caused by the influence of various factors, so that the sampling direction and the sampling depth are deviated from a pre-target, and when the foot of the user treads the pedal structure, the lantern ring 31 plays a guiding and limiting role for the main body rod 11, so that the axial deviation of the main body rod 11 cannot occur, and the sampling accuracy is ensured.

The pedal structure comprises a support rod 32 and a pedal plate 33, wherein the inner end of the support rod 32 is connected to the outer surface of the collar 31, and the outer end of the support rod is connected with the pedal plate 33 for treading feet. The two pedals 33 are separated by a reasonable distance through the support rod 32, so that the two legs can be slightly opened when a user steps on the pedals 33, and the body can exert force to carry out soil drilling. In addition, the anti-drop clip 331 capable of binding the foot is arranged on the pedal 33, so that the use state is more stable and reliable.

In addition, in order to avoid the slipping phenomenon between the pedal plate 33 and the soil surface, a plurality of anti-slip spines 332 are arranged on the bottom surface of the pedal plate 33, and the anti-slip spines 332 are used for penetrating into the soil surface, so that the pedal plate 33 can obtain the foundation fixing effect of the soil surface, and the slipping can be effectively prevented.

The lantern ring 31 is movably sleeved on the main body rod 11, the lantern ring 31 is very convenient to assemble and disassemble, and in order to enable the sampling device to be more convenient to carry, the lantern ring 31 and the pedal structure are also arranged to be detachably assembled. Based on this, the outer surface of the collar 31 is provided with a sleeve 311 extending outward, the sleeve 311 and the collar 31 can be fixedly connected by adopting a thermal welding process, and the support rod 32 is inserted and fixed in the sleeve 311.

For the fixing connection mode of the support rod 32 and the sleeve 311, at least one fixing rod 312 is arranged on the sleeve 311, usually, one or two fixing rods are arranged, the fixing rod 312 penetrates through the sleeve 311 and the support rod 32, two ends of the fixing rod are respectively in threaded connection with a locking nut 313, and the support rod 32 and the sleeve 311 can be firmly and fixedly connected together by screwing the locking nut 313 to abut against the outer surface of the sleeve 311. The fixing rod 312 and the locking nut 313 are fixedly connected, so that the reliability of the fixed connection is better guaranteed, and the assembly and disassembly are also very convenient.

The stress load of the collar 31 on the guide limit of the main body rod 11 is mainly concentrated on the support rod 32, so that the support rod 32 is more easily damaged than other structural components. Therefore, the outer surface of the collar 31 is provided with a plurality of connecting rods 41 extending outwards and supporting feet 42 mounted on the connecting rods 41 and supporting on the ground, the supporting action of the supporting feet 42 can share the stress load of the supporting rod 32, and the stability of the main body rod 11 during soil drilling can be further improved. Generally, the connecting rods 41 and the supporting feet 42 are three to four and are symmetrically arranged with respect to the collar 31.

The upper end edge of the collar 31 has an outward extending stop flange 314, and the stop flange 314 can abut against the stopper 51, so that the main body rod 11 cannot move axially downward, and the soil sampling drill 12 reaches a predetermined sampling depth.

The position of the limiting member 51 needs to be adjusted along the length of the main rod 11, so that the position can be adjusted according to different sampling depth requirements. Therefore, the limiting member 51 is annular and is sleeved outside the main body rod 11, two end portions of the limiting member 51 are bent to extend outwards, and a space is formed between the two end portions, a fastening member 52 for fastening the two end portions is connected between the two end portions of the limiting member 51, the two end portions of the limiting member 51 can be fastened through the fastening member 52, so that the position of the limiting member 51 relative to the main body rod 11 is locked, when the position needs to be adjusted, the fastening member 52 is loosened to slide the limiting member 51 along the main body rod 11, and the fastening member 52 is used for fastening after the position needs to be adjusted to a predetermined position.

In addition, in order to improve the sharpness of the earth boring bit 12 and to make it more labor-saving for the user to bore earth, thereby indirectly preventing the body rod 11 from being axially deviated during earth boring, the earth boring bit 12 has a cutting edge 121 for breaking earth on the lower end edge thereof.
