DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In traditional technology, when performing multi-point sampling, a sampling device is required to collect samples from multiple locations in sequence, which consumes manpower and material resources and has a long sampling cycle. In addition, frequent walking is required for sampling at different heights, which consumes physical strength.

[0021] In view of this, the present invention provides a soil multi-point collection device for soil and water loss control. Through the cooperation between the adjustment plate, the sampling tube, the internal pipeline and the locking unit, single multi-point and synchronous sampling of the soil surface at different heights is realized. On the one hand, the sampling cycle is short, and there is no need for manual multiple sampling, nor is there any need to move according to the sampling points. On the other hand, the positions of multiple sampling points are fixed, which is conducive to precise positioning of sampling.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Depend on Figure 1 , Figure 4 , Figure 5 and Figure 6It can be seen that a soil multi-point collection device for soil and water loss control in this case includes a crossbeam 1, and a plurality of adjustment plates 2 hinged in sequence are arranged on one side of the crossbeam 1. A sampling tube 3 is inserted into the interior of the adjustment plate 2. The adjustment plate 2 includes: an internal pipeline 21, which is opened inside the adjustment plate 2; a first connecting pipeline 22, which is opened on one side of the interior of the adjustment plate 2 and is connected to the internal pipeline 21 and extends to the side of the adjustment plate 2; a second connecting pipeline 23, which is opened on the other side of the interior of the adjustment plate 2 and is connected to the internal pipeline 21 and extends to the side of the adjustment plate 2; a plurality of sealing members 24 are arranged, which are respectively embedded in the first connecting pipeline 22 and the second connecting pipeline 23 away from the inner One end of the internal pipeline 21; the internal thread 25 is respectively opened on the inner wall of the first connecting pipeline 22 and the second connecting pipeline 23, and is located on the side of the sealing member 24 close to the adjusting plate 2; the locking unit 26 is arranged between the sampling tube 3 and the internal pipeline 21; wherein, the internal pipelines 21 of multiple adjusting plates 2 are interconnected through the first connecting pipeline 22 and the second connecting pipeline 23, and the sealing member 24 improves the sealing between the two first connecting pipelines 22 and the two second connecting pipelines 23 that are interconnected, and the first connecting pipeline 22 and the second connecting pipeline 23 located at the edge can be connected to the external pipeline through the internal thread 25, so that the locking unit 26 is used to fix the sampling tube 3 through the fluid pressure.

[0024] In the specific implementation process, it is worth pointing out that the crossbeam 1 serves as the overall connection structure of the soil multi-point collection device for soil and water loss control, connects multiple adjustment plates 2 to the traction equipment, and facilitates the application of power for sampling, wherein the adjustment plates 2 are hinged to each other, but it is worth noting that the hinge positions at both ends of an adjustment plate 2 are not the same, for example, one side is hinged to the lower left corner and the second adjustment plate 2, and the other side should be hinged to the upper right corner and the third adjustment plate 2, so that the multiple adjustment plates 2 can be folded to each other to reduce space occupation, which is convenient for storage, storage and transportation, and the sampling tube 3 can move up and down inside the adjustment plate 2, so that when sampling, the multiple sampling tubes 3 fall simultaneously due to gravity under the condition that the height of the adjustment plate 2 remains unchanged until the bottom contacts the ground and stops, and at this time, the heights of the multiple sampling tubes 3 are not the same, so that sampling can be performed synchronously at positions of multiple different planes; It is worth noting that the internal pipelines 21 and the second connecting pipelines 23 inside the multiple adjustment plates 2 are the same. The difference is that the first connecting pipeline 22 connected thereto, due to the different hinge positions between the multiple adjustment plates 2, the first connecting pipeline 22 should be connected to the first connecting pipeline 22 of another adjustment plate 2 while ensuring the connection with the internal pipeline 21. Therefore, the two first connecting pipelines 22 inside each adjustment plate 2 are not the same. This design is to ensure that when the multiple adjustment plates 2 are arranged in a straight line, the multiple internal pipelines 21 are connected to each other. The seal 24 is to improve the connection between the two adjustment plates. When the plates 2 are connected to each other, the sealing between the two first connecting pipes 22 and the two second connecting pipes 23 can be made of rubber material and glued to the adjusting plate 2. The design of the above structure is to achieve synchronous driving of the locking unit 26 inside each adjusting plate 2 to lock the sampling tube 3, so that when multiple sampling tubes 3 fall to the ground and are not located in the same plane, they can still be fixed synchronously, realizing sampling at the same depth (the depth of the sampling tube 3 inserted into the soil surface) in multiple positions and multiple planes, and after sampling, the beam 1 can be disassembled and the multiple adjusting plates 2 can be folded together to save space and facilitate storage and transportation.

[0025] It can be understood that in the soil multi-point collection device for soil and water loss control, there are two first connecting pipes 22 or second connecting pipes 23 located at the outermost edge, one of which is connected to the external pipe through an internal thread 25 to provide air pressure or hydraulic power, and the other internal thread 25 should be closed with a corresponding plug, or according to the sampling requirements, one or more new adjustment plates 2 should be connected and then closed with a corresponding plug.

[0026] Of course, after the cross beam 1 is separated from it, when the multiple adjustment plates 2 are folded together, they can be fixed by binding with ropes, or fixed by any other effective means, or they can be directly placed on a vehicle for transportation.

[0027] In one practicable manner, see Figure 3 , Figure 4 and Figure 6 The locking unit 26 includes: a connecting channel 261, which is opened inside the adjustment plate 2, located on one side of the sampling cylinder 3, and connected to the internal pipeline 21; a piston 262, which is installed on the inner wall of the connecting channel 261; a friction pad 263, which is fixed to the side of the surface of the piston 262 close to the sampling cylinder 3; wherein, through the connection between the connecting channel 261 and the internal pipeline 21, multiple pistons 262 are synchronously driven to approach the sampling cylinder 3, and the sampling cylinder 3 is fixed by the friction between the friction pad 263 and the sampling cylinder 3.

[0028] In the specific implementation process, it is worth pointing out that the connecting channel 261 is opened from the inside of the adjusting plate 2, one end of which is connected to the internal pipeline 21, and the other end of which is connected to the hole at the position where the sampling tube 3 passes through the adjusting plate 2. In this way, under pneumatic or hydraulic power, the piston 262 inside the connecting channel 261 can move toward the side close to the sampling tube 3, and press the friction pad 263 against the surface of the sampling tube 3, so as to fix the sampling tube 3.

[0029] It is worth mentioning that an exhaust hole connected to the connecting channel 261 should be provided at the edge of the hole where the sampling tube 3 passes through the adjusting plate 2, which can be directly opened on one side of the hole of the adjusting plate 2. In this way, during pneumatic operation, the piston 262 will not be unable to move due to the sealed space formed by the connecting channel 261 and the outer wall of the sampling tube 3, thereby ensuring communication with the outside atmosphere.

[0030] In one practicable manner, see Figure 1 , Figure 2 and Figure 3 A fixing unit 4 is provided between two adjacent adjustment plates 2, and the fixing unit 4 includes: a limiting member 41, which is provided on the outer wall of one adjustment plate 2; two groups of slide grooves 42 are provided, which are respectively opened on the surfaces of two adjacent adjustment plates 2, and are interconnected and slidably engaged with the inner wall of the limiting member 41; wherein, the inner wall of the limiting member 41 is respectively matched with the slide grooves 42 on the surfaces of the two adjustment plates 2 on both sides, so as to ensure that the two adjacent adjustment plates 2 are in a straight line state.

[0031] In the specific implementation process, it is worth pointing out that when the two adjustment plates 2 are arranged in a straight line, the two adjustment plates 2 can be fixed by the limit member 41 cooperating with the slide groove 42 on the surface of the two adjustment plates 2 at the same time, ensuring that the two adjacent first connecting pipes 22 or the two adjacent second connecting pipes 23 fit each other and the sealing is guaranteed. A damping pad or a fixing structure, such as a fixing screw, can be arranged between the limit member 41 and the slide groove 42, so as to ensure that the position of the limit member 41 is sufficiently stable to avoid accidental movement inside the slide groove 42.

[0032] Furthermore, the limiting member 41 is in a “C” shape and is wrapped around the edge of the adjusting plate 2 .

[0033] In the specific implementation process, it is worth pointing out that the "C"-shaped design, combined with the slide groove 42, can ensure that the limit member 41 is stably wrapped on the edge of the adjustment plate 2 and will not fall off. Of course, it can be removed from the position where the end slide groove 42 of the adjustment plate 2 passes through the adjustment plate 2.

[0034] In one practicable manner, see Figure 1 and Figure 7A connecting unit 5 is provided between the crossbeam 1 and the adjusting plate 2, and the connecting unit 5 includes: a connecting rod 51, one side of which is provided with a through hole and is sleeved on the outer wall of the crossbeam 1, and the other side is provided with a notch and fits on the surface of an adjusting plate 2; a limiting rod 52, which is provided below the connecting rod 51 and fits on the bottom of the adjusting plate 2; wherein, the crossbeam 1 and several adjusting plates 2 are connected by the connecting rod 51 and the limiting rod 52.

[0035] In the specific implementation process, it is worth pointing out that at least two groups of connecting units 5 are arranged to ensure the levelness and stability of the beam 1. The main purpose of the connecting rod 51 is to connect the beam 1 and one of the adjustment plates 2, and can provide downward pressure on the adjustment plate 2 through the beam 1, which is beneficial for the sampling tube 3 to enter the soil for sampling, and cooperate with the limit rod 52 to achieve a stable and effective connection. Since the multiple adjustment plates 2 are hinged to each other and can be fixed by the fixing unit 4, it is only necessary to connect one or several of the adjustment plates 2 to the beam 1 through the connecting unit 5 to achieve synchronous driving of the adjustment plate 2 to move downward or upward to complete the sampling action.

[0036] Furthermore, the limiting rod 52 is “L”-shaped and forms a closed area with the connecting rod 51 to fix one of the adjustment plates 2 .

[0037] In the specific implementation process, it is worth pointing out that the "L"-shaped design is more conducive to cooperating with the connecting rod 51 to wrap the adjustment plate 2 inside, thereby ensuring the effectiveness of the connection.

[0038] Furthermore, one end of the limiting rod 52 is inserted into the side of the connecting rod 51 , and a positioning pin 53 penetrating the connecting rod 51 is inserted into the top of the connecting rod 51 , and the positioning pin 53 also penetrates the limiting rod 52 .

[0039] In the specific implementation process, it is worth pointing out that the limit rod 52 is inserted into the connecting rod 51, which is convenient for adjustment, and it is convenient to split and adjust the position of the adjustment plate 2 and the connecting unit 5. Of course, the positioning pin 53 can effectively fix the connecting rod 51 and the limit rod 52, and the operation is very simple, which is convenient for splitting and fixing the beam 1 and several adjustment plates 2.

[0040] In one practicable manner, see Figure 1 A driving unit 6 is provided on the beam 1, and the driving unit 6 includes: a driving member 61, which is installed on the top platform of the beam 1; a mounting plate 62, which is installed on the end of the driving member 61 away from the beam 1; wherein the beam 1 and the sampling tube 3 are driven by the driving member 61 and the mounting plate 62 to complete the sampling action.

[0041] In the specific implementation process, it is worth pointing out that the driving member 61 can adopt a hydraulic cylinder, which can provide sufficient downward pressure and lifting force, suitable for synchronous sampling of multiple sampling tubes 3, and the purpose of the mounting plate 62 is to provide the driving member 61 with sufficient supporting force.

[0042] Furthermore, the driving unit 6 further includes a connecting member 63 , which is fixed to a side of the mounting plate 62 away from the crossbeam 1 .

[0043] In the specific implementation process, it is worth pointing out that the connecting member 63 can connect the soil multi-point collection device for soil and water loss control to a vehicle. For example, a tractor can be used for mountain sampling, and a tractor or other suitable vehicles can be used for flat sampling. Of course, depending on the different vehicles used, connecting members 63 of different shapes, specifications and models should be used to meet the installation and fixing requirements. This embodiment only provides a schematic diagram for reference. If a hydraulic cylinder is used as the driving member 61, it should be connected to the vehicle hydraulic system for easy control.

[0044] It is worth noting that, due to the connection with the vehicle, one of the first connecting pipeline 22 or the second connecting pipeline 23 located at the edge can be connected to the vehicle air pump pipeline (or equipped with an air pump separately) through the internal thread 25, and the driver controls it, and the other is sealed with a sealing plug corresponding to the internal thread 25, providing effective power for the locking unit 26, which is conducive to fixing the sampling tube 3.

[0045] In one practicable manner, see Figure 3 The outer wall of the sampling tube 3 is sleeved with a limiting tube 31 , and the limiting tube 31 is fixedly connected to the bottom of the adjustment plate 2 .

[0046] In the specific implementation process, it is worth pointing out that the limiting tube 31 and the adjusting plate 2 are integrally formed, with the aim of improving the connection stability between the sampling tube 3 and the adjusting plate 2 and ensuring that the sampling tube 3 and the adjusting plate 2 are in a vertical state. In this way, it is only necessary to ensure that the adjusting plate 2 is horizontal to ensure that the sampling tube 3 is perpendicular to the horizontal plane, which is conducive to accurate sampling.

[0047] Working principle: The soil multi-point collection device for soil and water loss control is connected to a vehicle through a connector 63. For example, a tractor can be used for sampling in mountains, and a tractor or other suitable vehicles can be used for sampling on flat land. Of course, depending on the vehicle used, connectors 63 of different shapes, specifications and models should be used accordingly. At the same time, the driving member 61 is connected to the vehicle hydraulic system, and one of the first connecting pipeline 22 or the second connecting pipeline 23 located at the edge is connected to the vehicle air pump pipeline or a separately equipped air pump through the internal thread 25, and the driver controls it, and the other is sealed with a sealing plug corresponding to the internal thread 25. According to the number of connected adjustment plates 2, select Select a suitable number of connecting units 5, first install them on the outer wall of the crossbeam 1, then pull out the positioning pin 53, pull the limiting rod 52, so that the limiting rod 52 and the connecting rod 51 are simultaneously sleeved on the outer wall of the adjusting plate 2, and then insert the limiting rod 52 back into the inner wall of the connecting rod 51, and fix it with the positioning pin 53. In this process, the adjusting plates 2 connected to the connecting units 5 are unfolded in turn, and the limiting members 41 cooperate with the slide grooves 42 on the surfaces of the two adjusting plates 2 at the same time to achieve the fixation of the two adjusting plates 2. The adjusting plates 2 not connected to the connecting units 5, that is, the adjusting plates 2 on both sides, can be folded and placed, and the traction vehicle is used to reduce shaking at the same time. Drive the traction vehicle to select a flat ground, unfold the unexpanded adjustment plate 2 at the edge, and fix it through the fixing unit 4 so that all the adjustment plates 2 are in a straight state. At this time, multiple internal pipes 21 are interconnected. The sealing member 24 improves the sealing between the two first connecting pipes 22 and the two second connecting pipes 23 when the two adjustment plates 2 are connected to each other. First, the soil multi-point collection device for soil and water loss control is placed above the ground through the driving member 61. For example, the bottom of the limiting pipe 31 is 5-10 cm away from the ground. At this time Insert multiple sampling tubes 3 into the interior of the adjustment plate 2 in sequence, and pass through the limiting tube 31 to fit the ground. Keep multiple sampling tubes 3 at a relatively uniform height. Use an air pump (built-in or additionally equipped on the tractor) to drive the piston 262 inside the connecting channel 261 to move toward the side close to the sampling tube 3, and press the friction pad 263 against the surface of the sampling tube 3 to fix the sampling tube 3. Raise the soil multi-point collection device for soil and water loss control to an ideal height through the driving member 61 to facilitate the next sampling. The sampling tube 3 will not interfere with the highest sampling point. Drive the traction vehicle to the sampling position, control the vehicle to align each sampling tube 3 with the sampling position, and deflate through the air pump. At this time, the sampling tube 3 loses the limit of the friction pad 263 and falls freely until the bottom contacts the ground and stops. Pressurize again through the air pump to press the friction pad 263 against the surface of the sampling tube 3 to fix the sampling tube 3. At this time, the driving member 61 is extended to simultaneously insert multiple sampling tubes 3 under the ground, so as to realize the depth sampling of the same depth sampling tubes in multiple positions and multiple planes into the soil surface. Retract the driving member 61 again. At this time, the soil inside each sampling tube 3 is collected in turn to complete the sampling.
