Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chestnut planting, in particular to a sampler for monitoring chestnut planting soil. Background Art
[0002] Chestnut is a deciduous tree plant of the genus Castanea in the Fagaceae family. It likes to grow in areas with plenty of sunshine and humid climate. It is a positive tree species, cold-resistant and drought-resistant. It has high requirements for soil and prefers sandy soil. Therefore, in the process of chestnut planting, in order to provide appropriate soil fertility utilization methods, it is often necessary to test the nutrient content in the soil so as to intervene in management in time.
[0003] Soil sampling is the first step to accurately analyze soil nutrients. The collected samples must be representative and effective, and the soil sampler is a very important tool in the soil sampling process. The current soil sampling method is to insert the soil sampler into the soil with force, rotate it vigorously, dig out the soil, and then put the soil sample into a sample bag and return to the laboratory for analysis. Since each plot of land generally has 10 to 20 sampling points, it is necessary to repeat sampling at different sampling points many times. Soil from different locations can easily be cross-mixed, resulting in a lack of strict accuracy in sampling. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 3The utility model discloses a chestnut planting soil monitoring sampler, comprising a handle 1 and a sampling cup 2. The left and right ends of the handle 1 are covered with a silicone sleeve 11, and the bottom end of the handle 1 is threadedly connected to an extension rod 3, and the bottom end of the extension rod 3 is threadedly connected to a drill tube 4, and a bayonet 41 is provided on the side wall of the drill tube 4. An elastic clamping block 21 is provided on the outer wall of the sampling cup 2, and the drill tube 4 is clamped in the elastic clamping block 21 and the bayonet 41. The set sampling cup 2 is installed in the drill tube 4 in a clamping manner. When the drill tube 4 is screwed into the soil, the soil can be pressed into the sampling cup 2 to complete the sampling. After that, the sampling cup 2 is removed and can be used as a sample storage device, and then another sampling cup 2 is reinstalled to continue the operation. Since the sampling cup 2 is engraved with an identification serial number 26, it is only necessary to record the corresponding sampling point according to the serial number each time sampling is taken, which is not easy to confuse, thereby ensuring the rigor of the detection. The sampler has a simple structure, high portability and is easy to use.
[0020] The sampling cup 2 includes a sample ring 22, a ring cover 23, a piston 24 and a cap 25. The sample ring 22 is engraved with an identification number 26.

[0027] Specifically, a blind hole 27 is provided on the outer wall of the cap 25 , and the elastic block 21 is located in the blind hole 27 .
[0028] In this embodiment, the blind hole 27 is used to increase the installation space for the elastic block 21. Figure 3As shown in , under the elastic action of the spring, the block can be freely extended and retracted.
[0029] Specifically, the top end of the piston 24 extends out of the sample ring 22 , and the top end of the piston 24 abuts against the inner top of the cap 25 .
[0030] In this embodiment, when the sample is to be tested, the cap 25 is removed, and then the piston 24 is pushed to push the sample out of the sample ring 22 .
[0031] When in use, before sampling, the ring cover 23 is removed and the sampling cup 2 is installed in the drill tube 4. When the drill tube 4 is screwed into the soil, the soil can be pressed into the sampling cup 2 to complete the sampling. The sampling cup 2 is then removed and used as a storage device for the sample. Then another sampling cup 2 is reinstalled to continue the operation. Since the sampling cup 2 is engraved with an identification number 26, each time sampling is performed, it is only necessary to record the corresponding sampling point according to the number, which is not easy to be confused and ensures the rigor of the detection. The sampler has a simple structure, high portability and is easy to use.
