[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a sampling tool for measuring minerals in potash fertilizer salt fields. The sampling tool for measuring minerals in potash fertilizer salt fields comprises a sampling portion 2, a limiting portion 23 and a placement frame 1. Among them, the sampling part 2 has a collection channel for collecting materials and a sampling through hole 22 connected to the collection channel, and the sampling through hole 22 has a feeding state for allowing materials to enter and a blocked state; the limiting part 23 is fixed to the outer periphery of the sampling part 2; the placement rack 1, along the axis of the collection channel, the sampling part 2 is respectively provided with a limiting part 23 and a placement rack 1 at two opposite ends, the placement rack 1 includes a limiting member 11 and a plurality of support members 13, and the plurality of support members 13 are arranged at intervals along the circumference of the limiting member 11, the support member 13 includes a support rod 139 supported on the salt field and a support leg 131 movably arranged along the axis relative to the support rod 139, the support leg 131 is connected to the limiting member 11, and the limiting member 11 is located at the outer periphery of the sampling part 2. Under the action of external force, the sampling part 2 is movably arranged relative to the limiting member 11.

[0026] In the above technical solution, the support rod 139 is placed on the surface of the potash salt field to support the sampling tool for potash salt field mineral surveying on the potash salt field. On the one hand, by moving the support leg 131 relative to the support rod 139, the distance between the limiting member 11 and the surface of the potash salt field can be adjusted. In this way, under the action of external force (pressed by the staff), the sampling part 2 is moved relative to the limiting member 11 and inserted into the potash salt field until the limiting part 23 abuts against the limiting member 11, thereby limiting the distance of the sampling part 2 inserted into the potash salt field. The distance of the sampling part 2 inserted into the interior of the potash salt field can be controlled according to the needs of the staff, thereby improving the accuracy of the sampling part 2 during sampling; on the other hand, in the process of the sampling part 2 moving relative to the limiting member 11, the limiting member 11 can limit the sampling part 2 to ensure that the sampling part 2 will not tilt during the insertion into the potash salt field, so as to solve the problem of the sampling part 2 being heavy and inconvenient to use in the prior art.

[0027] It should be noted that the working principle of the sampling tool for potassium fertilizer salt field mining in this embodiment can also be:

[0028] When it is necessary to conduct mineral sampling, first place the placement rack 1 on the top surface of the potash salt field, then press the sampling part 2 to make the sampling part 2 slide inside the limiting member 11 to be inserted into the potash salt field. After being inserted to a suitable distance, the sampling through hole 22 is placed in a feeding state to allow the soil of the potash salt field to enter the collection channel. When it is necessary to limit the distance of the sampling part 2 inserted into the potash salt field, the sampling part 2 can be driven by the limiting member 11 to move toward the surface away from the potash salt field, that is, the limiting member 11 and the sampling part 2 are raised.

[0029] like Figure 3 As shown, in an embodiment of the present invention, the support member 13 also includes: a drive motor 133, which is arranged on the support leg 131; a first gear 138, which is transmission-connected to the output shaft of the drive motor 133, and the first gear 138 is rotatably arranged on the support leg 131; a gear rod 1310, which is connected to the support rod 139, and the first gear 138 is meshed with the gear rod 1310, and the gear rod 1310 is slidingly connected to the support leg 131.

[0030] In the above technical solution, the first gear 138 is driven to rotate by the drive motor 133. Since the first gear 138 is meshed with the gear rod 1310, and the support rod 139 provided with the gear rod 1310 is supported on the surface of the potash salt field, the first gear 138 can move on the gear rod 1310, so that the first gear 138 drives the support leg 131 to move relative to the gear rod 1310, thereby adjusting the distance between the limiting member 11 and the surface of the potash salt field.

[0031] Furthermore, by making the gear rod 1310 slidably connected to the support leg 131 , it is possible to prevent the support leg 131 from being separated from the support rod 139 during the process of moving along the axial direction.

[0032] It should be noted that, in the embodiment of the present invention, the gear rod 1310 extends along the above-mentioned axial direction, and the gear rod 1310 is fixedly connected to the support rod 139 .

[0033] like Figure 3 As shown, in an embodiment of the present invention, the support member 13 also includes: a second gear 135, which is connected to the drive shaft of the drive motor 133, and the second gear 135 is rotatably provided on the support leg 131; a first rotating shaft 136, which is rotatably provided on the support leg 131, and the first gear 138 is fixed to the outer periphery of the first rotating shaft 136; a third gear 137, which is fixed to the outer periphery of the first rotating shaft 136, and the third gear 137 is meshed with the second gear 135, and the outer diameter of the third gear 137 is larger than the outer diameter of the second gear 135.

[0034] In the above technical solution, by providing the third gear 137 and the second gear 135, and the outer diameter of the third gear 137 is larger than the outer diameter of the second gear 135, the rotational speed of the output shaft of the drive motor 133 can be reduced while the output torque transmitted from the output shaft of the drive motor 133 to the first gear 138 can be increased, thereby improving the load capacity, so as to facilitate raising or lowering the support leg 131 and the sampling part 2 on the support leg 131.

[0035] Specifically, if Figure 3 As shown, the outer diameter of the first gear 138 is smaller than the outer diameter of the third gear 137. In this way, the output torque of the first gear 138 can be increased, thereby improving the load capacity, so as to facilitate raising or lowering the support leg 131 and the sampling part 2 on the support leg 131.

[0036] Specifically, if Figure 3 As shown, the support member 13 also includes a second rotating shaft 134 rotatably arranged on the support leg 131, and the second gear 135 is fixed to the outer periphery of the second rotating shaft 134. The second rotating shaft 134 is connected to the output shaft of the driving motor 133. In this way, the driving motor 133 drives the second rotating shaft 134 to rotate, thereby driving the second gear 135 to be rotatably arranged relative to the support leg 131.

[0037] like Figure 3 As shown, in the embodiment of the present invention, the support leg 131 is provided with a mounting groove and a slide groove connected to the mounting groove. The gear rod 1310 slides in the slide groove, and the first gear 138, the second gear 135, and the third gear 137 are located in the mounting groove. This allows a sliding connection between the gear rod 1310 and the support leg 131, thereby limiting the sliding direction of the gear rod 1310.

[0038] Because it is difficult to seal the sampling port of the potash salt field sampling tool in the prior art during sampling, materials in the middle or top of the potash salt field may enter the steel pipe, which may reduce the accuracy of data measurement.

[0039] Therefore, if Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the sampling part 2 includes: an insertion rod 21, which is provided with a collection channel and a sampling through hole 22 connected to the collection channel, and a limiting part 23 is connected to the outer periphery of the insertion rod 21; a plug 35, which is located in the collection channel and is movably arranged along the axis of the collection channel to switch the sampling through hole 22 between a feeding state and a blocking state.

[0040] Through the above arrangement, when the insertion rod 21 is inserted into the potash salt field, the plug 35 can be moved so that the plug 35 blocks the sampling through hole 22, so that the sampling through hole 22 is in a blocked state. In this way, materials in the middle and top parts of the potash salt field can be prevented from entering the collecting channel. When the insertion rod 21 reaches the designated position, the plug 35 can be moved along the axis of the collecting channel in a direction away from the sampling through hole 22, so that the sampling through hole 22 is connected to the inside of the collecting channel. In this way, the soil in the potash salt field can enter the collecting channel through the sampling through hole 22, so as to sample the potash salt field at the designated position, thereby improving the accuracy of data measurement.

[0041] Specifically, in the embodiment of the present invention, the plug 35 is made of rubber material.

[0042] Preferably, in the embodiment of the present invention, there are multiple sampling through holes 22.

[0043] like Figure 5 As shown, in the embodiment of the present invention, the sampling part 2 also includes: a rotating motor 32, which is arranged on the insertion rod 21; a screw rod 33, which is connected to the output shaft of the rotating motor 32, and the screw rod 33 is rotatably arranged in the collection channel; a connecting tube 34, which is connected to the plug 35, the screw rod 33 is passed through the connecting tube 34 and is spirally matched with the connecting tube 34, and the connecting tube 34 is movably arranged along the axis in the collection channel.

[0044] Through the above arrangement, the rotating motor 32 can rotate the screw rod 33 , and the screw rod 33 can drive the plug 35 to move in the collection channel through the connecting tube 34 , so that the plug 35 can block the sampling through hole 22 or stagger with the sampling through hole 22 .

[0045] like Figure 4As shown, in the embodiment of the present invention, the sampling portion 2 further includes: a fixing bracket 24 connected to the limiting portion 23; and a mounting member 31 for mounting a rotary motor 32. The mounting member 31 is fixed to the fixing bracket 24, and the output shaft of the rotary motor 32 extends out of the mounting member 31 and is connected to the screw rod. In this way, the rotary motor 32 can be fixed to the insertion rod 21 via the mounting member 31, the fixing bracket 24, and the limiting portion 23.

[0046] Preferably, in an embodiment of the present invention, there are a plurality of fixing frames 24 , and the plurality of fixing frames 24 are arranged in a ring array along the circumference of the limiting portion 23 , and each fixing frame 24 is L-shaped.

[0047] like Figure 3 As shown, in an embodiment of the present invention, the placement rack 1 further includes a support base 1311 fixedly connected to the outer periphery of the support rod 139, and the support base 1311 is located between the two ends of the support rod 139. In this way, the support rod 139 can be inserted into the potash salt pan, so that the support base 1311 is supported on the surface of the potash salt pan, thereby improving the support stability of the support rod 139.

[0048] like Figure 2 As shown, in the embodiment of the present invention, the limiting member 11 is an annular member, and a guiding groove 12 is provided on the annular member for slidingly cooperating with the sampling portion 2.

[0049] Through the above arrangement, the guide groove 12 can limit the sampling portion 2, so that the sampling portion 2 can move along the axis of the guide groove 12 to prevent the sampling portion 2 from tilting during the insertion into the potash salt field.

[0050] Preferably, in an embodiment of the present invention, the annular component is a circular ring structure.

[0051] Specifically, in the embodiment of the present invention, a plurality of support members 13 are arranged in a ring array along the outer wall of the circular ring structure.

[0052] like Figure 3 As shown, in the embodiment of the present invention, the support member 13 further includes a fixing member 132 fixed to the support leg 131, and the drive motor 133 is mounted on the fixing member 132. In this way, the drive motor 133 can be mounted on the support leg 131. The output shaft of the drive motor 133 passes through the fixing member 132 and the support leg 131 and is connected to the second rotating shaft 134.

[0053] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the support rod is placed on the surface of the potash salt field to support the sampling tool for potassium fertilizer salt field mineral surveying on the potash salt field. On the one hand, by moving the support leg relative to the support rod, the distance between the limiting member and the surface of the potash salt field can be adjusted. In this way, under the action of external force (by pressing by the staff), the sampling part is moved relative to the limiting member and inserted into the potash salt field until the limiting part abuts against the limiting member, thereby limiting the distance of the sampling part inserted into the potash salt field. The distance of the sampling part inserted into the interior of the potash salt field can be controlled according to the needs of the staff, thereby improving the accuracy of the sampling part during sampling; on the other hand, in the process of the sampling part moving relative to the limiting member, the limiting member can limit the sampling part to ensure that the sampling part will not tilt during the insertion into the potash salt field, so as to solve the problem of the heavy sampling part in the prior art causing inconvenience in use.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
