Description

Technical Field

[0001] The invention relates to the technical field of soil collection, and in particular to a land resources soil collection device and a use method thereof. Background Art

[0002] When studying the soil quality of land resources, it is necessary to sample different soils. In the process of sampling the soil, it is common to carry some tools such as shovels and ring cutters to dig the soil. When using the ring cutter, the drill bit and drill rod are knocked into the soil layer and then pulled out to dig out the soil stuck in the drill bit tube.

[0003] When sampling soil layers with relatively hard soil, it is generally necessary to use mechanical equipment to assist the drill bit and drill rod to insert into the soil layer. The top of the drill rod is generally connected to the mechanical equipment by bolts or threads. However, when some detection accuracy requirements are high or contaminated soil is detected, sampling at multiple sampling points is required. At the same time, the sampling equipment needs to be cleaned after each sampling so that there is no residue on the surface of the drill bit and drill rod, which will not affect the sampling data of the next sampling point.

[0004] However, due to limited outdoor conditions and limited time, it may be difficult to clean the sampling equipment quickly. Generally, multiple drill rods are carried and replaced each time they are used. However, when replacing the drill rods, the hands are easily contaminated with soil. If contaminated with contaminated soil, there may be certain risks. Even if gloves can be worn, they still need to take off the gloves to operate the sampling equipment, and repeat this process. On the one hand, it is cumbersome, and on the other hand, it is inevitable to contact with the soil. Therefore, the above soil collection method has certain defects. Summary of the invention

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

On the one hand, it is cumbersome, and on the other hand, it is inevitable to come into contact with the soil.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1 The embodiment of the invention discloses a land resources soil quality collection device and a use method thereof.

[0027] According to the attached Figure 1-12 As shown, a land resources soil quality collection device includes: Carrying unit 1; The collection unit 2 is used for soil quality collection work, and the collection unit 2 includes: 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; A driving motor 23, which is installed above the moving plate 22; A sampling assembly 24, which is disposed below the moving plate 22 and is in driving connection with the driving motor 23; 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; A switching unit 3, which is arranged between the output end of the driving motor 23 and the sampling component 24; 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; 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.

[0028] In the process of use, firstly, the vertical moving assembly 21 can drive the moving plate 22, the driving motor 23 and the sampling assembly 24 to move vertically, and at the same time, the driving motor 23 can drive the sampling assembly 24 to rotate, so that the sampling assembly 24 can be sampled after it moves downward into the soil layer; after the sampling is completed, the sampling assembly 24 is driven to move upward and reset, and at this time, another sampling assembly 24 is placed in the loading unit 4, and then the loading unit 4 and the unloading unit 5 are respectively moved from both sides to the switching unit 3; When the loading unit 4 contacts the switching unit 3, it can push the switching unit 3 and the sampling component 24 below it 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; pull the loading 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; pull the unloading unit 5 away from the switching unit 3 to reset, at this time the sampling component 24 after sampling is in a suspended state, and knocking the sampling component 24 causes the soil to fall, thereby realizing contactless removal of the sampled soil.

[0029] Furthermore, the carrying unit 1 includes: A support frame 11, which is used to carry the collection unit 2, the loading unit 4 and the unloading unit 5; The counterweight base 12 is fixedly mounted on the bottom of the support frame 11 to improve the stability of the support frame 11 .

[0030] Particularly disclosed, the vertical moving assembly 21 comprises: A support bar 211 is fixedly mounted in the support frame 11, and a slide groove is provided on the front side of the support bar 211; The screw rod 212 is rotatably arranged on the inner wall of the slide groove, and the top end of the screw rod 212 extends outward through the top of the support bar 211 and is fixedly connected to a rotating handle. The outer side of the screw rod 212 is threadedly connected to a nut block, which is slidably arranged in the slide groove and fixedly connected to the movable plate 22.

[0031] Because the nut block is fixedly connected to the movable plate 22, and the outer side of the screw rod 212 is threadedly connected to the nut block, when the rotating handle on the top is turned, the screw rod 212 can be driven to rotate, and the nut block can be driven to move vertically in the slide groove, so that the movable plate 22 moves accordingly, thereby causing the drive motor 23 and the movable plate 22 above and below the movable plate 22 to move vertically accordingly.

[0032] Specifically disclosed, the sampling assembly 24 includes: The positioning plate 241 has a T-block 242 and a connecting block 243 fixedly mounted above and below the positioning plate 241, and the T-block 242 is connected to the switching unit 3; The sampling cylinder 244 is fixed to the bottom of the connecting block 243 by means of bolts, and a hollow sampling cavity is formed at the bottom of the sampling cylinder 244 .

[0033] The positioning plate 241 and the T-block 242 can be connected to the switching unit 3. After the sampling tube 244 is inserted into the soil layer, the soil will be squeezed and compressed in the sampling cavity at the bottom of the sampling tube 244. After the sampling tube 244 is lifted, the soil sample can be obtained.

[0034] It is particularly disclosed that 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 switching unit 3 to position so that it can cooperate with the feeding unit 4 to switch the sampling component 24. The positioning component 25 includes: A positioning bar 251 is provided with a moving groove below the moving plate 22, one end of the positioning bar 251 is slidably arranged on the inner wall of the moving groove, and an extrusion bar 252 is fixedly installed on the other end of the positioning bar 251, and the extrusion bar 252 is in contact with the outer side of the switching unit 3; The pull rod 253 is movably inserted in the movable groove and fixedly connected to the end of the positioning bar 251. The outer side of the pull rod 253 is movably sleeved with a positioning spring 254, and the two ends of the positioning spring 254 are respectively connected to the end of the positioning bar 251 and the inner wall of the movable groove. The end of the pull rod 253 extends outward and is fixedly connected to a movable bar 255. The rotation of the movable plate 22 is provided with a limit bar 256, and the bottom end of the limit bar 256 is against the movable bar 255, and the positioning spring 254 is in a stretched state.

[0035] When it is necessary to collect data, the limit bar 256 is rotated upward so that the bottom end of the limit bar 256 is separated from the movable bar 255. At this time, the positioning spring 254 in the stretched state is automatically reset, thereby driving the positioning bar 251 to move in the moving groove, so that the extrusion bar 252 is separated from the outer side of the switching unit 3, and the end of the pull rod 253 and the movable bar 255 are moved outward. At this time, the switching unit 3 can rotate without affecting the driving motor 23 driving the sampling assembly 24 to rotate; After the collection is completed, when the sampling component 24 is switched by the loading unit 4, the switching unit 3 and the sampling component 24 are first driven to move upward until they reach the highest point. At this time, the vertical position of the switching unit 3 is positioned, and then the movable bar 255 is pushed, and the pull rod 253 is used to drive the positioning bar 251 to move in the moving groove until the extrusion bar 252 contacts the outside of the switching unit 3, and the switching unit 3 is pushed to rotate until the switching unit 3 and the extrusion bar 252 are in a parallel state, and then the limit bar 256 is rotated downward so that the bottom end of the limit bar 256 is against the movable bar 255, thereby completing the horizontal position positioning of the switching unit 3.

[0036] Particularly disclosed, the switching unit 3 comprises: The switch box 31 is fixedly installed below the output end of the drive motor 23. The switch box 31 has an empty slot 32 and two through-going T-slots 33 and slots 37. The T-block 242 is inserted into the T-slot 33, and the positioning plate 241 fits the bottom of the switch box 31. The switching block 34 is slidably disposed on the inner wall of the empty slot 32, and an extrusion slot 341 is provided inside the switching block 34, which is through-through from left to right and has an inclined surface on one side; The fixing block 35 is fixedly mounted on the bottom of the switching block 34, and two clamping blocks 351 are symmetrically arranged on the bottom of the fixing block 35. The two clamping blocks 351 are tightly fitted with both sides of the T-block 242, and the bottoms of the two clamping blocks 351 are inclined at the sides facing each other; The return spring 36 is fixedly connected between the switching block 34 and the inner top wall of the hollow groove 32 .

[0037] During use, under the action of the elastic force of the return spring 36, the positions of the switching block 34 and the fixed block 35 can be limited, so that the fixed block 35 cooperates with the two clamping blocks 351 symmetrically arranged at the bottom to fix the horizontal position of the T-block 242. The T-block 242 cannot move vertically when inserted in the T-slot 33, so the position of the T-block 242 is fixed, and when the driving motor 23 drives the switching box 31 to rotate, the T-block 242 can be driven to rotate accordingly.

[0038] 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 .

[0039] Particularly disclosed, the feeding unit 4 comprises: A feeding slide rail 41 is mounted on the support frame 11, and 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; The feeding U-shaped bar 43 is fixedly connected to the end of the feeding extension bar 42 on the outside, and a guide 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.

[0040] It should be emphasized that the elastic force of the second pressing spring 46 is smaller than that of the first pressing spring 381 .

[0041] 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 fits 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, so that it will not move laterally. At this time, the feeding extension bar 42 will be pushed to move toward the switching unit 3. Since the guide bar 44 is long, the end of the guide bar 44 will be first inserted into the slot 37 on the switching box 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, the guide bar 44 will push the switching block 34 to slide upward on the inner wall of the empty slot 32 during the continuous movement. On the one hand, it compresses the return spring 36, and on the other hand, it drives the fixed block 35 and the two clamping blocks 351 to move upward, thereby separating the two clamping blocks 351 from the T-block 242. At this time, the feeding U-shaped bar 43 is on the side of the switching box 31; Then, the unloading unit 5 is moved to the other side of the switching box 31, and the loading U-shaped bar 43 is continuously pushed to move, so that the positioning plate 241 above it contacts the positioning plate 241 below the switching box 31, and the positioning plate 241 below the switching box 31 is moved to the other side accordingly, and this is continued so that the new positioning plate 241 is moved to the bottom of the switching box 31, and the new T-block 242 slides into the T-slot 33 in the switching box 31, until the collected sampling assembly 24 falls into the unloading unit 5, and the new T-block 242 passes through the second limiting hemispherical block 45 and is located below the fixed block 35 and in the first limiting hemispherical blocks 38 on both sides; At this time, pull the feeding extension strip 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 extrusion spring 381 connected to the first limiting hemispherical block 38 is greater than the second extrusion spring 46 connected to the second limiting hemispherical block 45, the T-block 242 will stay in the first limiting hemispherical blocks 38 on both sides, so that it is separated from the feeding U-shaped strip 43 until the guide strip 44 is detached from the switching box 31. The switching block 34 is reset under the action of the reset spring 36, so that the two clamping blocks 351 at the bottom of the fixed block 35 are tightly fitted with the two sides of the T-block 242, thereby realizing the automatic installation of the new sampling component 24.

[0042] A method for using a land resources soil quality collection device comprises the following steps: Step 1: First, the vertical moving assembly 21 can drive the moving plate 22, the driving motor 23 and the sampling assembly 24 to move vertically, and the driving motor 23 can drive the sampling assembly 24 to rotate, so that the sampling assembly 24 can be sampled after it moves downward into the soil layer; Step 2: After sampling, the sampling assembly 24 is driven to move upward and reset. At this time, another sampling assembly 24 is placed in the loading unit 4, and then the loading unit 4 and the unloading unit 5 are respectively moved from both sides to the switching unit 3; 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; 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; 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.
