Description

Technical Field

[0001] The present invention relates to the technical field of soil collection, and specifically to a device for collecting soil resources of land and its usage method. Background Art

[0002] When studying the soil resources of land, it is necessary to take samples of different soils. During the process of sampling soil, it is common to carry tools such as shovels and core cutters to dig the soil. When using a core cutter, after knocking the drill bit and drill rod into the soil layer and pulling them out, the soil stuck in the drill bit tube is taken out.

[0003] When sampling soil layers with relatively hard soil, it is generally necessary to use mechanical equipment to assist in inserting the drill bit and drill rod into the soil layer. The top of the drill rod is generally connected to the mechanical equipment by bolts or threads. However, when high-precision detection or detection of polluted soil is required, sampling at multiple sampling points is needed, and at the same time, the sampling equipment needs to be cleaned after each sampling to ensure that there is no residue on the surface of the drill bit and drill rod, so as not to affect the sampling data of the next sampling point.

[0004] Under limited outdoor conditions and limited time, it may be difficult to quickly clean the sampling equipment thoroughly. Generally, multiple drill rods are carried and the drill rods are replaced each time they are used. However, when replacing the drill rod, the hands are easily contaminated with soil. If contaminated with polluted soil, there may be certain risks. Even if gloves can be worn, the gloves still need to be taken off to operate the sampling equipment. Repeating this process is cumbersome on the one hand and it is inevitable to come into contact with the soil on the other hand. Therefore, there are certain defects in the above-mentioned soil collection method. Summary of the Invention

At this time, the vertical position of the switching unit is positioned. Then push the movable bar, and use the pull rod to drive the positioning bar to move in the moving groove until the extrusion bar contacts the outside of the switching unit and pushes the switching unit to rotate until the switching unit is parallel to the extrusion bar. Then turn the limiting bar downward so that the bottom end of the limiting bar abuts against the movable bar, thus completing the horizontal position positioning of the switching unit.

[0050] 3. The land resource soil sampling device can use the second limiting hemispherical block and the second compression spring to play a certain blocking role on the connecting block. When the sampled sampling assembly moves above the placement frame after sampling, a disposable sampling bag or sampling box can be placed in the placement frame. Tap the sampling cylinder so that the soil sample in the sampling cavity at the bottom of the sampling cylinder can fall downward to complete contactless sampling. After sampling, pull the T-shaped block outward to remove the whole sampling assembly. Since the T-shaped block will not contact the contaminated soil, there will be no risk of hand contact with the contaminated soil. Description of the Drawings

By providing a device for collecting soil quality of land and resources and its usage method, it solves the problem that it may be difficult to quickly clean the sampling equipment under limited outdoor conditions and limited time. Generally, multiple drill pipes are carried, and the drill pipes can be replaced each time they are used. However, when replacing the drill pipes, it is very easy for the hands to be contaminated with soil. If contaminated with polluted soil, there may be certain risks. Even if gloves can be worn, it is still necessary to take off the gloves to operate the sampling equipment. Repeating this process is cumbersome on the one hand and it is inevitable to come into contact with the soil on the other hand.

[0067] When the feeding unit 4 comes into contact with the switching unit 3, it can push the switching unit 3 and the sampling assembly 24 below it to separate, and push it towards the discharging unit 5, while another sampling assembly 24 moves towards the lower part of the switching unit 3; pull the feeding unit 4 away from the switching unit 3 to reset, and at the same time, a new sampling assembly 24 is automatically installed, so as to realize the contactless switching of the sampling assembly 24; pull the discharging unit 5 away from the switching unit 3 to reset. At this time, the sampled sampling assembly 24 is in a suspended state. Tap the sampling assembly 24 so that the soil drops accordingly, thereby realizing the contactless extraction of the sampled soil.

[0068] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0069] Embodiment 1

[0070] The embodiments of the present invention disclose a device for collecting soil quality of land and resources and its usage method.

[0071] According to the attached Figures 1-12 As shown, a device for collecting soil quality of land and resources includes:

[0072] A bearing unit 1;

[0073] A collecting unit 2, which is used for soil collection work, and the collecting unit 2 includes:

[0074] A vertical moving component 21, which is installed on the bearing unit 1 and is drivingly connected to a moving plate 22 on its front side;

[0075] A driving motor 23, which is installed above the moving plate 22;

[0076] A sampling assembly 24, which is arranged below the moving plate 22 and is in transmission connection with the driving motor 23;

[0077] The vertical moving assembly 21 cooperates with the driving motor 23 to drive the rotation and vertical movement of the sampling assembly 24, thereby realizing the sampling work of the sampling assembly 24;

[0078] A switching unit 3, which is arranged between the output end of the driving motor 23 and the sampling assembly 24;

[0079] A feeding unit 4, which is arranged on one side of the collecting unit 2. The feeding unit 4 can load another sampling assembly 24 to cooperate with the switching unit 3 to realize non-contact automatic switching of the sampling assembly 24 below the driving motor 23;

[0080] A discharging unit 5, which is arranged on the other side of the collecting unit 2, receives the sampled sampling assembly 24, and takes out the sampled soil in a non-contact manner.

[0081] During the use process, first, the vertical moving assembly 21 can drive the moving plate 22, the driving motor 23 and the sampling assembly 24 to move vertically. At the same time, the driving motor 23 can drive the sampling assembly 24 to rotate, so that soil sampling can be realized after the sampling assembly 24 moves downward into the soil layer; after sampling, it drives the sampling assembly 24 to move upward and reset. At this time, another sampling assembly 24 is placed in the feeding unit 4, and then the feeding unit 4 and the discharging unit 5 are respectively moved from both sides towards the switching unit 3;

[0082] When the feeding unit 4 contacts the switching unit 3, it can push the switching unit 3 and the sampling assembly 24 below it to separate, and push it towards the discharging unit 5, while another sampling assembly 24 moves towards the lower part of the switching unit 3; pull the feeding unit 4 away from the switching unit 3 to reset, and at the same time, the new sampling assembly 24 is automatically installed, so as to realize non-contact switching of the sampling assembly 24; pull the discharging unit 5 away from the switching unit 3 to reset. At this time, the sampled sampling assembly 24 is in a suspended state. Tap the sampling assembly 24 so that the soil falls accordingly, thereby realizing non-contact taking out of the sampled soil.

[0083] Furthermore, the bearing unit 1 includes:

[0084] A support frame 11, which is used to bear the collecting unit 2, the feeding unit 4 and the discharging unit 5;

[0085] A counterweight base 12, which is fixedly installed at the bottom of the support frame 11 and is used to improve the stability of the support frame 11.

[0086] Specifically disclosed, the vertical movement component 21 includes:

[0087] A support bar 211, which is fixedly installed in the support frame 11, and a chute is provided on the front surface of the support bar 211;

[0088] A lead screw 212, which is rotatably arranged on the inner wall of the chute, and the top end of the lead screw 212 passes through the top of the support bar 211 and extends outward and is fixedly connected with a rotating handle. A nut block is threadedly connected to the outer side of the lead screw 212, and the nut block is slidably arranged in the chute and fixedly connected with the moving plate 22.

[0089] Since the nut block is fixedly connected with the moving plate 22, and at the same time the outer side of the lead screw 212 is threadedly connected with the nut block, when the rotating handle at the top is rotated, the lead screw 212 can be driven to rotate, and at the same time the nut block can be driven to move vertically in the chute, so that the moving plate 22 moves accordingly, and thus the driving motor 23 above and below the moving plate 22 and the moving plate 22 move vertically accordingly.

[0090] Specifically disclosed, the sampling component 24 includes:

[0091] A positioning plate 241, with a T-shaped block 242 and a connecting block 243 fixedly installed above and below it respectively. The T-shaped block 242 is connected to the switching unit 3;

[0092] A sampling cylinder 244, which is fixedly installed at the bottom of the connecting block 243 by bolts, and a hollow sampling cavity is provided at the bottom of the sampling cylinder 244.

[0093] By using the positioning plate 241 and the T-shaped block 242, they can be connected to the switching unit 3. At the same time, after the sampling cylinder 244 is inserted into the soil layer, the soil will be squeezed and compressed in the sampling cavity at the bottom of the sampling cylinder 244. After the sampling cylinder 244 is lifted, a soil sample can be obtained.

[0094] Specifically disclosed, a positioning component 25 is installed between the moving plate 22 and the switching unit 3. The positioning component 25 is used to control the positioning of the switching unit 3 so that it can cooperate with the feeding unit 4 to switch the sampling component 24. The positioning component 25 includes:

[0095] A positioning bar 251, a moving groove is provided below the moving plate 22, one end of the positioning bar 251 is slidably arranged on the inner wall of the moving groove, the other end of the positioning bar 251 is fixedly installed with a pressing bar 252, and the pressing bar 252 is in contact with the outer side of the switching unit 3;

[0096] The pull rod 253 is movably inserted into the moving groove and fixedly connected to the end of the positioning strip 251. A positioning spring 254 is movably sleeved outside the pull rod 253, and both ends of the positioning spring 254 are respectively connected to the end of the positioning strip 251 and the inner wall of the moving groove. The end of the pull rod 253 extends outward and is fixedly connected to the movable strip 255. A limiting strip 256 is rotatably arranged on the moving plate 22. The bottom end of the limiting strip 256 abuts against the movable strip 255, and the positioning spring 254 is in a stretched state.

[0097] When the collection work needs to be carried out, the limiting strip 256 is rotated upward so that the bottom end of the limiting strip 256 is separated from the movable strip 255. At this time, the positioning spring 254 in the stretched state automatically resets, thereby driving the positioning strip 251 to move in the moving groove, so that the extrusion strip 252 is separated from the outside of the switching unit 3, and the end of the pull rod 253 and the movable strip 255 move outward. At this time, the switching unit 3 can rotate without affecting the driving motor 23 to drive the sampling assembly 24 to rotate;

[0098] After the collection is completed, when using the feeding unit 4 to switch the sampling assembly 24, first drive the switching unit 3 and the sampling assembly 24 to move upward until the highest point. At this time, the vertical position of the switching unit 3 is positioned. Then push the movable strip 255, drive the positioning strip 251 to move in the moving groove by the pull rod 253 until the extrusion strip 252 contacts the outside of the switching unit 3, and push the switching unit 3 to rotate until the switching unit 3 is parallel to the extrusion strip 252. Then rotate the limiting strip 256 downward so that the bottom end of the limiting strip 256 abuts against the movable strip 255, thereby completing the positioning of the horizontal position of the switching unit 3.

[0099] Specifically disclosed, the switching unit 3 includes:

[0100] The switching box body 31 is fixedly installed below the output end of the driving motor 23. An empty groove 32, a T-shaped groove 33 and a slot 37 that penetrate through both sides are opened inside the switching box body 31. The T-shaped block 242 is inserted into the T-shaped groove 33, and the positioning plate 241 is attached to the bottom of the switching box body 31;

[0101] The switching block 34 is slidably arranged on the inner wall of the empty groove 32, and an extrusion groove 341 that penetrates through the left and right and has an inclined surface on one side is opened inside the switching block 34;

[0102] The fixed block 35 is fixedly installed at the bottom of the switching block 34, and two clamping blocks 351 are symmetrically arranged at the bottom of the fixed block 35. The two clamping blocks 351 are in close contact with both sides of the T-shaped block 242, and the opposite sides of the bottoms of the two clamping blocks 351 are both inclined;

[0103] The reset spring 36 is fixedly connected between the switching block 34 and the inner top wall of the empty slot 32.

[0104] During the use process, under the action of the elastic force of the reset spring 36, the positions of the switching block 34 and the fixed block 35 can be limited. Furthermore, the fixed block 35 and the two clamping blocks 351 symmetrically arranged at the bottom can fix the horizontal position of the T-shaped block 242. Since the T-shaped block 242 cannot move vertically when inserted into the T-shaped slot 33, the position of the T-shaped block 242 is fixed. When the driving motor 23 drives the switching box body 31 to rotate, the T-shaped block 242 can be driven to rotate accordingly.

[0105] Furthermore, a first limiting hemispherical block 38 is embedded on the inner wall of the T-shaped slot 33, and a first extrusion spring 381 is fixedly connected between the first limiting hemispherical block 38 and the inner wall of the T-shaped slot 33.

[0106] Specifically disclosed, the feeding unit 4 includes:

[0107] A feeding slide rail 41 is installed on the support frame 11. A feeding extension bar 42 is slidably arranged in the feeding slide rail 41, and the end of the feeding extension bar 42 extends outward.

[0108] A feeding U-shaped bar 43 is fixedly connected to the end of the feeding extension bar 42 outside. A guiding bar 44 is fixedly installed above the feeding U-shaped bar 43. A second limiting hemispherical block 45 is embedded on the inner wall of the feeding U-shaped bar 43, and a second extrusion spring 46 is arranged between the second limiting hemispherical block 45 and the inner wall of the feeding U-shaped bar 43.

[0109] It should be emphasized that the elastic force of the second extrusion spring 46 is less than that of the first extrusion spring 381.

[0110] When switching the sampling assembly 24 after collecting soil, first place the new sampling assembly 24 on the feeding U-shaped bar 43, so that the positioning plate 241 is in contact with the upper part of the feeding U-shaped bar 43, and the connecting block 243 is inserted into the feeding U-shaped bar 43. At this time, the second limiting hemispherical block 45 and the second extrusion spring 46 can play a certain limiting role on the connecting block 243 to prevent it from moving horizontally.

[0111] At this time, the feeding extension bar 42 will be pushed towards the switching unit 3. Since the guiding bar 44 is relatively long, the end of the guiding bar 44 will first insert into the slot 37 on the switching box body 31, and enter the extrusion groove 341 inside the switching block 34 through the slot 37. Since one side of the extrusion groove 341 is an inclined surface, during the continuous movement of the guiding bar 44, it will push the switching block 34 to slide upward along the inner wall of the empty groove 32. On the one hand, the reset spring 36 is compressed, and on the other hand, the fixed block 35 and the two clamping blocks 351 are driven to move upward, so that the two clamping blocks 351 are separated from the T-shaped block 242. At this time, the feeding U-shaped bar 43 is located on the side of the switching box body 31;

[0112] Then, move the discharging unit 5 to the other side of the switching box body 31, and continue to push the feeding U-shaped bar 43 to move, so that the positioning plate 241 above it contacts the positioning plate 241 below the switching box body 31, and the positioning plate 241 below the switching box body 31 is moved to the other side accordingly. Continuing like this, the new positioning plate 241 is moved to the bottom of the switching box body 31, and the new T-shaped block 242 slides into the T-shaped groove 33 in the switching box body 31 until the sampled sampling assembly 24 after collection drops into the discharging unit 5, and the new T-shaped block 242 passes through the second limiting hemispherical block 45 and is located below the fixed block 35 and the first limiting hemispherical blocks 38 on both sides;

[0113] At this time, pull the feeding extension bar 42 to reset. Although the connecting block 243 will be blocked by the second limiting hemispherical block 45, since the elastic force of the first compression spring 381 connected to the first limiting hemispherical block 38 is greater than the elastic force of the second compression spring 46 connected to the second limiting hemispherical block 45, the T-shaped block 242 will stay in the first limiting hemispherical blocks 38 on both sides, separating it from the feeding U-shaped bar 43. Until the guiding bar 44 disengages from the switching box body 31, the switching block 34 resets under the action of the reset spring 36, and then the two clamping blocks 351 at the bottom of the fixed block 35 are closely attached to both sides of the T-shaped block 242, thus realizing the automatic installation of the new sampling assembly 24.

[0114] A usage method of a land resource soil sampling device includes the following steps:

[0115] Step 1: First, the vertical moving component 21 can drive the moving plate 22, the driving motor 23, and the sampling assembly 24 to move vertically. At the same time, the driving motor 23 can drive the sampling assembly 24 to rotate, so that soil sampling can be realized after the sampling assembly 24 moves downward into the soil layer;

[0116] Step 2: After sampling, drive the sampling assembly 24 to move upward and reset. At this time, place another sampling assembly 24 in the feeding unit 4, and then move the feeding unit 4 and the discharging unit 5 towards the switching unit 3 from both sides;

[0117] Step 3: When the loading unit 4 contacts the switching unit 3, the switching unit 3 and the sampling component 24 below it can be pushed to separate and push it toward the unloading unit 5, and the other sampling component 24 moves toward the bottom of the switching unit 3;

[0118] Step 4: Pull the feeding unit 4 away from the switching unit 3 to reset, and at the same time, the new sampling component 24 is automatically installed, thereby realizing contactless switching of the sampling component 24;

[0119] Step five, pull the unloading unit 5 away from the switching unit 3 to reset it. At this time, the sampling component 24 after sampling is in a suspended state, and the sampling component 24 is knocked to make the soil fall, thereby realizing the contactless removal of the sampled soil.

[0122] Carrying unit 1;

[0123] The collection unit 2 is used for soil quality collection work, and the collection unit 2 includes:

[0124] A vertical moving assembly 21 is mounted on the carrying unit 1, and a moving plate 22 is connected to the front of the assembly;

[0125] A driving motor 23, which is installed above the moving plate 22;

[0126] A sampling assembly 24, which is disposed below the moving plate 22 and is in driving connection with the driving motor 23;

[0127] The vertical moving component 21 cooperates with the driving motor 23 to drive the sampling component 24 to rotate and move vertically, thereby realizing the sampling work of the sampling component 24;

[0128] A switching unit 3, which is arranged between the output end of the driving motor 23 and the sampling component 24;

[0129] A loading unit 4 is arranged at one side of the collecting unit 2. The loading unit 4 can load another sampling component 24 and cooperate with the switching unit 3 to realize contactless automatic switching of the sampling component 24 under the driving motor 23;

[0130] The unloading unit 5 is arranged at the other side of the collecting unit 2, receives the sampling assembly 24 after sampling, and removes the sampled soil without contact.

[0131] Specifically disclosed, the sampling assembly 24 includes:

[0132] The positioning plate 241 is fixedly installed with a T-shaped block 242 and a connecting block 243 above and below it respectively. The T-shaped block 242 is connected to the switching unit 3;

[0133] The sampling cylinder 244 is fixedly installed at the bottom of the connecting block 243 through bolts, and a hollow sampling cavity is provided at the bottom of the sampling cylinder 244.

[0134] Specifically disclosed, the feeding unit 4 includes:

[0135] The feeding slide rail 41 is installed on the support frame 11. A feeding extension bar 42 is slidably arranged in the feeding slide rail 41, and the end of the feeding extension bar 42 extends outward;

[0136] The feeding U-shaped bar 43 is fixedly connected to the end of the feeding extension bar 42 outside the device. A guiding bar 44 is fixedly installed above the feeding U-shaped bar 43. A second limiting hemispherical block 45 is embedded on the inner wall of the feeding U-shaped bar 43, and a second compression spring 46 is arranged between the second limiting hemispherical block 45 and the inner wall of the feeding U-shaped bar 43.

[0137] Specifically disclosed, the discharging unit 5 includes:

[0138] The discharging slide rail 51 is installed on the support frame 11. A discharging extension bar 52 is slidably arranged in the discharging slide rail 51, and the end of the discharging extension bar 52 extends outward;

[0141] Pins can be inserted into both the feeding slide rail 41 and the discharging slide rail 51. The pins can be used to limit the positions of the feeding extension bar 42 and the discharging extension bar 52, so that the feeding extension bar 42 and the discharging extension bar 52 will not move during the sampling operation.

[0142] Moreover, the discharging U-shaped bar 53 and the feeding U-shaped bar 43 have the same structure, and a second limiting hemispherical block 45 and a second compression spring 46 are arranged inside them. The second limiting hemispherical block 45 and the second compression spring 46 can play a certain blocking role on the connecting block 243. Then, when the sampling assembly 24 after sampling moves above the placement frame 54, a disposable sampling bag or sampling box can be placed in the placement frame 54. By knocking the sampling cylinder 244, the soil sample in the sampling cavity at the bottom of the sampling cylinder 244 can fall downward to complete non-contact sampling. After sampling, by pulling the T-shaped block 242 outward, the entire sampling assembly 24 can be removed. Since the T-shaped block 242 does not contact the contaminated soil, there will be no risk of hand contact with the contaminated soil.
