Description

Technical Field

[0001] The utility model relates to the technical field of sampling frames, in particular to a foldable sampling frame for green manure yield measurement. Background Technique

[0002] In agricultural scientific research and production, green manure yield measurement sampling is a crucial task, which is directly related to soil fertility assessment, crop rotation planning, and the formulation of agricultural sustainable development strategies. However, traditional green manure yield measurement sampling methods often have many inconveniences and potential safety hazards. First of all, during the sampling process, staff usually need to carry a variety of tools, such as knives, rulers, etc. This not only increases the burden of carrying but also easily leads to safety accidents due to tool scattering or misuse during operation. Secondly, the traditional sampling frame design often lacks flexibility, cannot be adjusted in size according to actual needs, and is not easy to fix, resulting in the sampling frame being easily displaced by external forces during the sampling process, affecting the stability and accuracy of sampling. Therefore, we propose a foldable sampling frame for green manure yield measurement. Content of the Utility Model

[0003] The purpose of the utility model is to provide a foldable sampling frame for green manure yield measurement, which avoids safety accidents caused by accidental touch during carrying or handling, effectively ensures the safety of staff, and enables them to work better;

[0004] To achieve the above object, the utility model provides the following technical solution: A foldable sampling frame for green manure yield measurement, including a housing and folding arms. The folding arms are connected to the housing through a horizontal rotating shaft. Sliding grooves are provided inside both the housing and the folding arms, and sliding blocks and knives are slidably connected in the sliding grooves. A knife sheath is provided inside the sliding block, and the knife sheath is adapted to the knife.

[0005] Further: Fixing holes are evenly arranged at the bottom of the folding arms and the housing, and fixing rods are installed inside the fixing holes.

[0006] Further: A storage compartment is provided on the top surface of the sliding block, and a vertical rotating shaft is installed inside the storage compartment.

[0007] Further: A telescopic ruler is fixedly installed on the surface of the vertical rotating shaft, and the telescopic ruler is adapted to the storage compartment after being folded.

[0008] Further: The blade of the knife is located on one side of the sliding block, and connecting rods are installed at both the front and rear ends of the knife.

[0009] Further: A pull ring is installed at one end of the connecting rod away from the knife.

[0010] Further: Threaded rods are installed on the bottom surfaces of both the housing and the folding arms, and drill bits are installed on the bottom surfaces of the threaded rods.

[0011] With the above technical solution, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model can push the sliding block to the front of the housing through the sliding groove, and then use the horizontal rotating shaft to rotate and fold the folding arm for folding and storage. At the same time, a tool for sampling and cutting is provided inside the housing, so that the staff does not need to carry an additional tool during the sampling work, effectively preventing the occurrence of safety accidents. At the same time, the tool case arranged inside the sliding block can store the tool after folding, avoiding safety accidents caused by accidental touch during carrying or handling, effectively ensuring the safety of the staff and enabling them to work better;

[0013] 2. By setting fixing holes and fixing rods at the bottom of the housing and the folding arm, the sampling frame can be firmly fixed on the ground, preventing it from moving due to external forces during the sampling process, ensuring the stability and safety of sampling.

[0027] Preferably: Threaded rods 8 are installed on the bottom surfaces of both the housing 4 and the folding arms 2, and drill bits 7 are installed on the bottom surfaces of the threaded rods 8 to be fixed on the ground to prevent sliding during the yield measurement process and affect the results.

[0028] Example 1. Please refer to the attached Figure 1 - attached Figure 4, the sampling frame is mainly composed of a housing 4 and folding arms 2. The folding arms 2 are connected to the housing 4 through a horizontal rotation axis 3, enabling the folding arms 2 to rotate and fold around the horizontal rotation axis 3. Sliding grooves 12 are provided inside both the housing 4 and the folding arms 2. A sliding block 16 is slidably connected inside the sliding grooves 12. The sliding block 16 can not only freely slide within the sliding grooves 12 to adjust the sampling range of the sampling frame, but also has a knife housing 14 inside. A cutting tool 13 for sampling is installed inside the knife housing 14. When the sliding block 16 is pushed to the front of the housing 4, the cutting tool 13 can extend from the knife housing 14, facilitating the staff to carry out sampling cutting work. This design enables the staff to perform sampling work without carrying an additional cutting tool 13, effectively preventing safety accidents. At the same time, when the cutting tool 13 is not in use, it can be retracted into the knife housing 14, avoiding safety accidents caused by accidental touch during carrying or handling, and ensuring the safety of the staff.

[0029] Embodiment 2. Please refer to the attached Figure 1 - attached Figure 4 , equally spaced fixing holes 9 are opened at the bottoms of the housing 4 and the folding arms 2, and fixing rods 10 are installed inside the fixing holes 9. When the sampling frame is placed on the ground, the sampling target can be fixed in layers by inserting the fixing rods 10 into the fixing holes 9, preventing movement due to external forces during sampling and ensuring the stability and safety of sampling. In addition, a storage compartment 15 is opened on the top surface of the sliding block 16. A retractable ruler 1 is installed inside the storage compartment 15 through a vertical rotation axis 11. The retractable ruler 1 can be folded and stored inside the storage compartment 15 when not in use, and can be quickly unfolded through the vertical rotation axis 11 when needed. This not only provides a convenient storage space for auxiliary tools such as the retractable ruler 1, but also realizes the quick unfolding and folding of the retractable ruler 1 through the vertical rotation axis 11, facilitating the user to measure the size or depth of the sampling area at any time. This design not only provides a convenient storage space for auxiliary tools such as the retractable ruler 1, but also further improves the accuracy and efficiency of sampling.

[0030] The sliding block 16 can be pushed to the front of the housing 4 through the sliding groove 12, and then the folding arms 2 can be rotated and folded using the horizontal rotation axis 3. At the same time, a cutting tool 13 for sampling is provided inside the housing 4. This enables the staff to perform sampling work without carrying an additional cutting tool 13, effectively preventing safety accidents. At the same time, the knife housing 14 provided inside the sliding block 16 can store the cutting tool 13 after folding, avoiding safety accidents caused by accidental touch during carrying or handling, and effectively ensuring the safety of the staff, enabling them to work better.

[0031] Working principle:

[0032] First, push the sliding block 16 to the front of the housing 4 through the sliding groove 12, and pull the tool 13 out of the knife housing 14 through the pull ring to prepare for sampling and cutting. Then, use the horizontal rotating axis 3 to rotate the folding arm 2 to the required angle, adjust the size and shape of the sampling frame to adapt to different sampling needs, then place the sampling frame in the target sampling area, and firmly fix the sampling frame to the ground through the bottom fixed drill bit 7 to ensure stability and safety during the sampling process. During the sampling process, the telescopic ruler 1 on the top of the sliding block 16 can be used to measure the size or depth of the sampling area at any time as needed to improve the sampling accuracy. After the sampling is completed, the tool 13 is stored back in the knife housing 14, and the sampling frame is folded and stored by rotating the folding arm 2 for easy carrying and storage. At this point, the entire workflow ends.
