Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue soil collection, in particular to a collector for in-situ soil sampling of crop pesticide residues. Background Art

[0002] Pesticide residues refer to the general term for trace amounts of pesticide precursors, toxic metabolites, degradation products and impurities that remain in organisms, harvests, soil, water and the atmosphere after a period of use without being decomposed. When collecting pesticide residues, it is necessary to collect the soil in situ, so a soil collector is needed. The "Portable Sampling Device for In-situ Soil of Pesticide Residues in Crops" disclosed in the publication number "CN218584359U" has solved the technical drawback of being unable to sample the soil in layers. However, in actual use, collectors with similar structures still have many defects. For example, after the soil sampling is completed, it is necessary to discharge and collect it. When the soil is discharged, it will be scattered because it is too loose, which makes it impossible for the staff to accurately collect the layered soil. For this reason, we have designed a collector for in-situ soil sampling of pesticide residues in crops to solve the above problems. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a collector for in-situ soil sampling of pesticide residues in crops, which solves the problem that the sampled soil needs to be discharged when it is collected in layers, and the discharged sampled soil will be scattered.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-5 The present invention provides a technical solution: a sampler for in-situ soil sampling of crop pesticide residues, including a sampling mechanism 1 and an operating mechanism 2 assembled on the top of the sampling mechanism 1. The sampling mechanism 1 includes a soil sampling drill bit 101. A knife edge 102 is provided at the bottom of the soil sampling drill bit 101. A sampling groove 105 is provided on the back of the soil sampling drill bit 101. A sampling plate 4 is slidably installed inside the sampling groove 105. A locking plate 401 is fixedly installed on the top of the sampling plate 4. Two groups of pressing plates 5 are rotatably installed at the rear side of the top of the soil sampling drill bit 101 through shaft rods 501. One ends of the two groups of pressing plates 5 are slidably installed with limit pins 502. Limit holes 402 for cooperating with the limit pins 502 are provided on both sides of the top of the locking plate 401. The operating mechanism 2 includes an operating rod 201. A telescopic sleeve 202 is sleeved on the upper part of the outside of the operating rod 201. A holding rod 203 is fixedly installed on the top of the telescopic sleeve 202. A collar 3 is fixedly installed on the top of the outside of the operating rod 201. Connecting plates 301 are fixedly installed on both sides of the collar 3. Foot pedals 302 are fixedly installed on the outer sides of the two groups of connecting plates 301. Anti-slip patterns 303 are provided on the tops of the two groups of foot pedals 302.

[0021] Based on the above structure settings, the collector for in-situ soil sampling of crop pesticide residues is composed of a sampling mechanism 1 and an operating mechanism 2. Among them, the sampling mechanism 1 is the soil sampling mechanism, and the operating mechanism 2 is the operating mechanism during the use of the collector. With the help of the operating mechanism 2, it is convenient for the staff to use the collector. Specifically, during the working process, the soil sampling drill bit 101 can be inserted into the soil, so that the soil with crop residues can be sampled through the soil sampling drill bit 101. The cutting edge 102 increases the sharpness of the bottom of the soil sampling drill bit 101. When the collector encounters crop roots during soil sampling, it can quickly cut them off, thus increasing the speed when the soil sampling drill bit 101 is inserted into the soil. The operating rod 201 and the holding rod 203 are convenient for the staff to control when operating the soil sampling drill bit 101, increasing the convenience of the staff when operating and using the collector. The telescopic sleeve 202 can adjust the height of the holding rod 203, so that it is convenient for people of different heights to sample the soil through the sampler, increasing the comfort of people of different heights when using the collector. The collar 3 outside the operating rod 201 can install and fix the connecting plate 301 and the foot pedal 302. The foot pedal 302 is convenient for the staff to insert the soil sampling drill bit 101 into the soil by stepping on it. The anti-slip pattern 303 increases the friction on the top of the foot pedal 302, improving the stability when the staff contacts the foot pedal 302. The sampling plate 4 can close the sampling groove 105, and the pressing plate 5 can press and limit the top of the sampling plate 4, ensuring the stability when the sampling plate 4 closes the sampling groove 105. When the soil sampling drill bit 101 is pulled out after sampling the soil, the sampling plate 4 can be pulled out in the sampling groove 105, so that it is convenient for the staff to accurately collect the stratified soil inside the soil sampling drill bit 101, increasing the accuracy of the staff when collecting the soil in layers through the collector and avoiding the situation where the soil in the soil sampling drill bit 101 needs to be discharged before collection.

[0022] Furthermore, a transparent window 103 is fixedly installed on the front surface of the soil sampling drill bit 101, and a scale 104 is arranged on the surface of the soil sampling drill bit 101 on one side of the transparent window 103. Among them, the transparent window 103 is convenient for people to observe the inside of the soil sampling drill bit 101, and the scale 104 can measure the soil sampling depth inside the soil sampling drill bit 101.

[0023] Furthermore, holding sleeves 204 are fixedly installed on both sides outside the holding rod 203, and limiting rings 205 are fixedly installed on the inner sides of the two groups of holding sleeves 204. Among them, the holding sleeves 204 increase the softness of the outer wall of the holding rod 203, improving the comfort and stability of the staff when holding the holding rod 203. The limiting rings 205 can limit the staff when holding outside the holding sleeves 204.

[0024] Further, a locking shaft 207 is threadedly installed below the back of the telescopic sleeve 202, and a plurality of locking holes 206 for cooperating with the locking shaft 207 are equidistantly formed in the back of the operating rod 201. Among them, the locking shaft 207 can be inserted into the locking hole 206 by rotation, so as to lock the extension and contraction of the telescopic sleeve 202 on the outer wall of the operating rod 201, ensuring the stability of the telescopic sleeve 202 during the extension adjustment on the outer wall of the operating rod 201.

[0025] Further, a sliding plate 403 is fixedly installed on the outer wall of the sampling plate 4, and a sliding groove 106 for cooperating with the sliding plate 403 is formed inside the sampling groove 105. Among them, the sliding plate 403 is slidably installed in the sliding groove 106, so as to limit the sampling plate 4 when it is installed in the sampling groove 105, ensuring the stability and accuracy of the sampling plate 4 slidably installed inside the sampling groove 105.

[0026] Further, a pull plate 504 is fixedly installed at the top of the limit pin 502 through the pressing plate 5, and a support spring 503 sleeved on the outer wall of the limit pin 502 is fixedly installed inside the pressing plate 5. Among them, the pull plate 504 facilitates the staff to lift the limit pin 502, so as to facilitate the staff to adjust the pressing plate 5. The support spring 503 can elastically press down the limit pin 502, thus ensuring the stability when the limit pin 502 is inserted into the limit hole 402.
