DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1:

[0019] like Figure 1 , Figure 2As shown, the utility model provides a soil survey sampling device, comprising a stabilizing cylinder 1, a rotating seat 2 coaxially rotatably connected to the top of the stabilizing cylinder 1, and a vertical rod 3 coaxially slidably connected to the rotating seat 2. An operating handle is connected to the top of the vertical rod 3. Relative rotational motion and axial relative motion can occur between the vertical rod 3 and the stabilizing cylinder 1. The bottom end of the vertical rod 3 passes through the rotating seat 2 and extends to the inside of the stabilizing cylinder 1, where a sampling mechanism 4 is connected. The bottom end of the stabilizing cylinder 1 is rotatably connected to a plurality of stabilizing frames 5, which are evenly distributed along the circumference of the stabilizing cylinder 1. A synchronous adjustment mechanism 6 is provided on the stabilizing cylinder 1 and is transmission-connected to the stabilizing frame 5.

[0020] Before sampling, the bottom end of the stabilizing cylinder 1 is first brought into contact with the soil surface, and the multiple stabilizing frames 5 are unfolded and brought into contact with the soil surface through the synchronous adjustment mechanism 6. The vertical rod 3 is driven by the handle to move so that the sampling mechanism 4 is brought into contact with the soil surface for sampling. During the sampling process, due to the support of the stabilizing frame 5, it can be ensured that the sampling mechanism 4 will not deflect significantly during the operation of the operator, which is convenient for operation.

[0021] Specifically, the synchronous adjustment mechanism 6 includes an axial movement component 610 disposed on the stabilizing cylinder 1, a transmission rod 620 rotatably connected to the axial movement component 610, and a positioning component 630 for limiting the axial movement component 610, wherein the transmission rod 620 is rotatably connected to the stabilizing frame 5;

[0022] The positioning assembly 630 is used to limit the moving path of the axial moving assembly 610 and to position the axial moving assembly 610 when the axial moving assembly 610 moves to a state sufficient for the stabilizing frame 5 to be unfolded, so as to maintain the stability of the stabilizing frame 5;

[0023] Specifically, the axial movement assembly 610 is an annular slide 611 sleeved on the stabilizing cylinder 1, and a plurality of hinge seats 612 fixedly connected to the bottom of the annular slide 611, and the hinge seat 612 is rotatably connected to the transmission rod 620;

[0024] When the annular slide 611 moves axially, the transmission rod 620 drives the stabilizing frame 5 to rotate. During use, the stabilizing frame 5 is driven to rotate to a horizontal state, which can improve the supporting and stabilizing effect of the vertical rod 3 during the sampling process. After use, the stabilizing frame 5 is rotated to a position close to the stabilizing cylinder 1, which can reduce the occupied space.

[0025] In order to facilitate the positioning effect, in a further implementation, as Figure 2As shown, the positioning assembly 630 includes a slide groove 631 arranged on the side of the stabilizing cylinder 1 and parallel to its axis, a slider 632 fixed on the inner side of the annular slide seat 611 and slidably matched with the slide groove 631, a plug hole 633 is arranged at the bottom of the slide groove 631, a positioning through hole 634 is arranged on the annular slide seat 611 and can be matched with the plug hole 633 through a latch 635, when the slider 632 contacts the groove wall at the bottom of the slide groove 631, the positioning through hole 634 and the plug hole 633 just correspond, and another plug hole can also be arranged on the top of the slide groove 631, when the stabilizing frame 5 is folded, the latch 635 can be used to cooperate with the plug hole at the top, so as to ensure that the stabilizing frame 5 after folding will not be unfolded;

[0026] In order to facilitate the folding of the stabilizing frame 5, in a further embodiment, the stabilizing frame 5 includes two parallel and vertically arranged side plates 501, one end of the two side plates 501 is rotatably connected to the stabilizing cylinder 1, and the transmission rod 620 extends between the two side plates 501 and is rotatably connected to the middle thereof;

[0027] When the stabilizing frame 5 is folded, the stabilizing frame 5 can enter between the two side panels 501;

[0028] In order to improve the stability of the stabilizing cylinder 1 during sampling, in a further embodiment, a plug plate 502 is provided at the bottom of one end of the stabilizing frame 5 away from the stabilizing cylinder 1, and the plug plate 502 is fixedly connected to the stabilizing frame 5. An insert rod 101 is fixedly connected to the bottom of the stabilizing cylinder 1, and the plug plate 502 and the insert rod 101 are inserted into the soil to improve stability.

[0029] Embodiment 2:

[0030] In order to reduce the danger of the plug board 502 after the stabilizing frame 5 is folded, the difference from the first embodiment is that Figure 3 As shown, the plug plate 502 is disposed between the two side plates 501 and the middle part thereof is rotatably connected to the side plates 501, one end of the plug plate 502 is rotatably connected to a connecting rod 503, and the other end of the connecting rod 503 is rotatably connected to the transmission rod 620;

[0031] When the stabilizing frame 5 is folded, the transmission rod 620 moves, and drives the inserting plate 502 to rotate through the connecting rod 503, so that the inserting plate 502 rotates to between the two side plates 501 to prevent the inserting plate 502 from scratching the operator.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
