Description

Technical Field

[0001] The invention relates to the technical field of plant tuber sampling, and in particular to a sweet potato sampling drilling tool. Background Art

[0002] Sweet potato tubers are a type of underground modified stems, which are swollen and irregular block structures at the end of underground stems and can store nutrients. In order to understand the quality, pesticide residues and other conditions of sweet potatoes, sweet potatoes generally need to be sampled and tested.

[0003] The utility model patent with the announcement number CN213180804U discloses a sweet potato sampling drilling tool, wherein the sample storage barrel is arranged at the rotating end of the hand drill, so that the hand drill can drive the sample storage barrel to rotate, and the connecting clamp is also provided with a clamping plate, and the two clamping plates are arranged symmetrically at intervals, and the spacing between the two clamping plates is adjusted by means of bolts and nuts, that is, the bolts are connected with the nuts after passing through the two clamping plates. When the gap between the two clamping plates becomes smaller, and because the sample storage barrel and the sampling knife are simultaneously arranged in the clamping cavity of the connecting clamp, the connecting clamp can clamp the sample storage barrel and the sampling knife. At this time, the rotation energy of the sample storage barrel is transmitted to the sampling knife. When the sampling knife drills into the sweet potato during rotation, a columnar sample can be taken out from the sweet potato; in order to facilitate the removal of the sample from the sample storage barrel, the spacing between the two clamping plates can be increased to separate the connecting clamp from the sample storage barrel and the sampling knife respectively, and then the sample storage barrel and the sampling knife are held by hand at the interval between the sample storage barrel and the sampling knife to take out the sample from the sample storage barrel and the sampling knife respectively.

[0004] The above-mentioned prior art has certain shortcomings in actual use. It can only sample and process the sweet potato samples brought into the laboratory. When sampling the sweet potatoes in the soil, it is impossible to effectively separate the soil, and the sampling steps are relatively cumbersome. Summary of the invention

The inner surface of the surrounding cylinder 10 is fixedly connected with a spiral convex node 11, and the side surface of the surrounding cylinder 10 is located on one side of the annular ring 12 and is equidistantly provided with grooves 13. The surface of one end of the surrounding cylinder 10 is provided with saw teeth 14. When sampling sweet potatoes, the user can control the hand drill 1 with one hand and hold the bracket 18 with the other hand. After starting the hand drill 1, the saw teeth 14 on the output end will continuously cut the soil in the process until it penetrates into the position of the sweet potato, and then cooperate with the spiral convex node 11 and the viscosity of the soil itself to The drilled sweet potato will slowly move into the connecting frame 9, and soil will be mixed into it. With the linkage of the plug block 8, the entire surrounding cylinder 10 will also rotate accordingly, so as to throw out the entrained soil, and the drilled sweet potato sample will remain in the connecting frame 9 under the influence of the gradual spring 17.

After the sampling is completed, even if a large amount of soil is thrown out, a small amount of soil impurities will stick to the surface of the sweet potato sample. In order to reduce the subsequent cleaning workload, when the user feeds the sweet potato sample while holding the electric drill 1 horizontally, it will fall on the surface of the carrying plate 21, and then the vibration motor 19 is controlled to operate, and the entire soft belt 20 will shake.

A slider is fixedly connected to the surface of one end of the short rod 31. Guide grooves 34 are equidistantly provided on the surface of the guide disk 33, and an opening 35 is provided on the surface of the guide disk 33 at the middle. When the drilling and sampling operation is completed, in order to prevent the sweet potato sample from falling due to loose soil, the user can hold the guide in advance. The disk 33 is then rotated forcefully, and the user will first feel a certain resistance. At this time, the abutment spring 32 will abut against the surface of the slider, and then the abutment spring 32 will cooperate with the connecting tube 27 to make the guide disk 33 embedded in the card hole 23 at the outer side, and wait until the force on the surface of the guide disk 33 gradually increases, the slider will retract, and the guide disk 33 can be rotated at this time, which will eventually drive the entire connecting tube 27 to move outward until the slider is embedded in the card hole 23 on the inner side, and at the same time, the blocking piece 25 fixedly connected to the connecting tube 27 will slowly move toward the center until the edges of the five groups of blocking pieces 25 are attached to each other, completing the blocking of the connecting groove 24, and then the subsequent operations can be carried out.

[0019] The working principle of the present invention is as follows: when sampling sweet potatoes, the user can control the hand drill 1 with one hand and hold the bracket 18 with the other hand. After starting the hand drill 1, the saw teeth 14 on the output end will continuously cut the soil in the process until it reaches the position of the sweet potatoes. Then, in combination with the spiral convex section 11 and the viscosity of the soil itself, the drilled sweet potatoes will slowly move into the connecting frame 9, and the soil will also be mixed into it. With the linkage of the plug block 8, the entire surrounding cylinder 10 will also rotate accordingly, so that the entrained soil will be thrown out, and the drilled sweet potato sample will be The sweet potato sample will remain inside the connecting frame 9 under the influence of the gradual spring 17. When it is needed to be taken out later, the user only needs to turn the push plate 15 to drive the gradual spring 17 to contract after the hand drill 1 stops working, and then the sweet potato sample can fall out of the gap of the connecting frame 9. When the drilling and sampling operation is completed, in order to prevent the sweet potato sample from falling due to loose soil, the user can hold the guide disk 33 in advance and then rotate the guide disk 33 forcefully. First, the user will feel a certain resistance, and at this time the abutment spring 32 will abut on the surface of the slider. The abutment spring 32 will cooperate with the connecting tube 27 to make the guide plate 33 embedded in the card hole 23 at the outer side. When the force on the surface of the guide plate 33 gradually increases, the slider will retract. At this time, the guide plate 33 can rotate, which will eventually drive the entire connecting tube 27 to move outward until the slider is embedded in the card hole 23 on the inner side. At the same time, the blocking piece 25 fixedly connected to the connecting tube 27 will slowly move toward the center until the edges of the five groups of blocking pieces 25 are attached to each other, completing the blocking of the connecting groove 24, and then the back can be carried out. In the subsequent operation, after the sampling is completed, even if a large amount of soil is thrown out, a small amount of soil impurities will stick to the surface of the sweet potato sample. In order to reduce the subsequent cleaning workload, the user holds the electric drill 1 horizontally and cuts the sweet potato sample. The sweet potato sample will fall on the surface of the supporting plate 21. Then the vibration motor 19 is controlled to operate, and the entire soft belt 20 will shake. At the same time, with the dead weight of the supporting plate 21 and the sweet potato sample, a certain vibration will occur, thereby controlling the soil impurities adhered to the sweet potato sample to fall off, so as to facilitate subsequent carrying.
