DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] This utility model provides an embodiment of a soil sampling tool for agricultural plant protection:

[0032] like Figures 1 to 6 As shown, the sampling tube includes a sampling rod 1 and a sampling cylinder 2 connected to the lower end of the sampling rod 1. The lower end of the sampling cylinder 2 is open and has several serrations 205 arranged in a ring array to facilitate the sampling cylinder 2 to cut and sample the soil. The upper end of the sampling rod 1 has two handles 4, which are located on both sides of the sampling rod 1 to facilitate the user to hold the tube with both hands and apply sampling force. The inside of the sampling cylinder 2 is provided with a first half tube 301 and a second half tube 302. The first half tube 301 and the second half tube 302 are spliced ​​to form a sample tube 3 with an open lower end. A hinge 303 connects the first half tube 301 and the second half tube 302. The outer surface of the sampling cylinder 2 has a semi-cylindrical outlet 201, and a semi-cylindrical cover plate 10 is detachably connected inside the outlet 201.

[0033] During sampling, place the lower opening of the sampling tube 2 at the sampling position, and then press down on the handle 4. This will apply downward pressure to the sampling tube 2 through the sampling rod 1. During this process, the sampling tube 2 will drive the sample tube 3 to insert into the ground. The soil below the sampling tube 2 will also enter the sampling tube 2 and eventually enter the sample tube 3. After the sampling is completed, pull up on the handle 4 to remove the sampling tube 2, the sample tube 3, and the soil that has entered the sample tube 3 from the ground.

[0034] Then, by removing the cover plate 10 from the sampling tube 2, the sample tube 3 is exposed, as follows: Figure 4 As shown, the sample tube 3 can then be taken out through the extraction port 201. Since the extraction process does not require contact with the soil sample, it can effectively prevent the cylindrical soil sample from becoming loose. The extracted sample tube 3 can be placed in an external sample storage box for transportation. When it is necessary to take a sample again, a new sample tube 3 can be placed in the sampling tube 2, and then the cover plate 10 can be put back on the extraction port 201.

[0035] To prevent the first half-tube 301 from separating from the second half-tube 302 during transportation, which could damage the cylindrical soil sample, several turns of adhesive tape 304 can be wrapped and bonded around the outer surface of the sample tube 3, as shown in the figure below. Figure 5As shown, while ensuring that the opening of the sample tube 3 is placed upwardly in the external sample storage box, when the soil sample in the sample tube 3 needs to be detected and analyzed, the rubber band 304 is first removed, then the sample tube 3 is placed horizontally, and the first half tube 301 is located at the upper portion, then the second half tube 302 located at the upper portion is slowly turned upwardly through the hinge 303, and the second half tube 302 is separated from the first half tube 301, so as to open the sample tube 3, and then the soil sample can be detected.

[0036] As shown in Figure 5 , Figure 7 and Figure 8 , the inner diameter of the sampling cylinder 2 is the same as that of the sample tube 3, and the inner surface of the sampling cylinder 2 is provided with a first installation cavity 202 matched with the sample tube 3, and the inner surface of the sample tube 3 is provided with a second installation cavity 1003 matched with the sample tube 3, and the first installation cavity 202 and the second installation cavity 1003 are spliced to form a cylindrical fixing cavity for fixing the sample tube 3;

[0037] The setting of the fixing cavity not only can ensure that the sample tube 3 is fixed in the sampling cylinder 2, so as to prevent the sample tube 3 from falling off from the sampling cylinder 2 during sampling, but also can make the inner diameter of the sample tube 3 the same as that of the sampling cylinder 2, so as to avoid the step between the lower end opening of the sample tube 3 and the inner surface of the sampling cylinder 2, and thus when the sampling cylinder 2 is inserted into the ground, it can be ensured that the soil can smoothly slide into the sample tube 3, and at the same time, the soil is not damaged by extrusion.

[0038] As shown in Figure 4 , Figure 9 and Figure 10 , the lower portion of the cover plate 10 is provided with a clamping block 1001, and the sampling cylinder 2 is provided with a clamping groove 203 matched with the clamping block 1001, and the clamping block 1001 is inserted into the inside of the clamping groove 203;

[0039] As shown in Figure 11 , the upper portion of the cover plate 10 is provided with an insertion block 1002, the insertion block 1002 is provided with a fixing hole 10021, the upper portion of the sampling cylinder 2 is fixed with a connecting piece 204, the connecting piece 204 is provided with a connecting groove 2041, the insertion block 1002 is inserted into the connecting groove 2041, and the connecting groove 2041 is provided with a fixing assembly connected with the fixing hole 10021;

[0040] The fixing assembly comprises an insertion rod 701 and a spring 702, the insertion rod 701 is slidingly connected in the connecting groove 2041, one end of the insertion rod 701 is inserted into the fixing hole 10021, the other end of the insertion rod 701 extends out of the connecting groove 2041 and is fixed with a first dismounting handle 703;

[0041] When it is necessary to remove the cover plate 10, pull the insert rod 701 upward by the first disassembly handle 703 to make the insert rod 701 slide upward and compress the spring 702 to a certain extent. At the same time, the insert rod 701 is pulled out from the fixing hole 10021 on the insert block 1002, and the fixing of the insert block 1002 is released. Then, pull the upper part of the cover plate 10 outward so that the cover plate 10 and the locking block 1001 can rotate outward around the part of the locking block 1001 that contacts the opening of the slot 203. During this process, the insert block 1002 will be pulled out from the connecting groove 2041. Then, pull the cover plate 10 outward to make the locking block 1001 pull out from the slot 203, and the disassembly of the cover plate 10 is completed.

[0042] When it is necessary to install the cover plate 10 on the outlet 201, first keep the cover plate 10 tilted and insert the locking block 1001 into the locking groove 203 to align the lower end of the cover plate 10 with the lower part of the outlet 201. Then, flip the cover plate 10 towards the outlet 201 so that the cover plate 10 slowly covers the outlet 201. During this process, pull the insertion rod 701 upward by the first disassembly handle 703 and compress the spring 702 to a certain extent until the insertion block 1002 is re-inserted. Return the tool to the connecting groove 2041, and then release the first disassembly handle 703. At this time, under the rebound force of the spring 702, the insertion rod 701 can be reset, and the lower end of the insertion rod 701 can be inserted back into the fixing hole 10021 on the insertion block 1002 to fix the cover plate 10. This achieves the purpose of quick disassembly and assembly of the cover plate 10. Moreover, the disassembly and assembly process is simple and convenient, thus making the sampling tool more convenient and easy to use.

[0043] This utility model provides a second embodiment of a soil sampling tool for agricultural plant protection:

[0044] like Figure 12 As shown, the fixing component includes a bolt 801 and a threaded hole 802 opened on the connector 204. The bolt 801 is threaded into the threaded hole 802, and one end of the bolt 801 is inserted into the fixing hole 10021, while the other end extends outward into the connecting groove 2041 and is fixed with a second disassembly handle 803.

[0045] At this time, the insert 1002 is fixed in the connecting groove 2041 by the bolt 801, and the cover plate 10 is fixed in the outlet 201. When it is necessary to disassemble the cover plate 10, the bolt 801 is turned by the second disassembly handle 803. At this time, under the action of the threaded hole 802, the bolt 801 can be moved slowly upward and its lower end can be pulled out from the fixing hole 10021. This can also achieve the purpose of releasing the fixation of the insert 1002. Then the cover plate 10 can be removed in the same way as above, and the disassembly of the cover plate 10 can also be achieved.

[0046] When installing the cover plate 10, the cover plate 10 is installed back into the taking-out port 201, and the bolt 801 is screwed reversely again to insert the lower end of the cover plate 10 back into the fixing hole 10021, thereby fixing the cover plate 10.
