Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of grain seed sampling, particularly to a layered sampling mechanism of a grain seed sampler. BACKGROUND
[0002] The layered sampling mechanism of the grain seed sampler is used for collecting samples from grain seed stacks in layers to ensure the representativeness and uniformity of the samples. Through layered design, the mechanism can accurately collect seeds at different depths, avoiding the problem of uneven samples caused by single-layer sampling. It helps to improve the accuracy of detection, ensures that the test results can truly reflect the quality status of the entire grain batch, and is widely used in the fields of grain quality monitoring and detection.
[0003] However, the layered sampling mechanism of the existing grain seed sampler lacks a precise layered isolation mechanism during operation, which easily collects the same layer of grain seeds together, which may cause the collected samples to not accurately represent the characteristics of the target layer of grain, resulting in data deviation during subsequent detection and analysis, distorted measurement results, and inability to provide reliable basis for grain quality evaluation, variety identification, and other work, seriously affecting the scientificity and accuracy of related decisions.
[0004] Therefore, the layered sampling mechanism of the grain seed sampler is provided to meet the needs. UTILITY MODEL CONTENTS
[0005] The utility model aims at solving the shortcomings in the prior art and provides a layered sampling mechanism of a grain seed sampler.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a layered sampling mechanism of a grain seed sampler, comprising:
[0007] A handle and a support column arranged at the bottom of the handle;
[0008] A sampling assembly arranged inside the support column, the sampling assembly comprising a baffle fixed inside the support column, a sliding plate arranged inside the baffle, a support plate arranged inside the support column, a sliding groove arranged on the inner wall of the support plate, a spring plate arranged at the bottom of the baffle away from the sliding plate, a fixed rod arranged at the top of the support plate, and a guide groove arranged on the fixed rod;
[0009] A contraction assembly arranged at the top of the handle, the contraction assembly comprising a lifting rod fixed at the top of the handle, a connecting ring arranged at the bottom of the lifting rod, a first connecting rope arranged on the connecting ring, and a lifting rod storage groove arranged at the top of the handle.
[0010] In a preferred embodiment, the other end of the first connecting rope away from the connecting ring is connected to the baffle.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by pulling the top lifting rod, the first connecting rope drives the baffle to retract through the guide groove, closing the material receiving slot and preventing internal materials from falling out.
[0012] In a preferred embodiment, a spring is provided at the bottom of the baffle, and the other end of the spring is connected to the support plate.
[0013] The beneficial effect of adopting the above-mentioned further solution is that when the lifting rod is pulled to retract the baffle, the spring is stretched and stores energy. After the lifting rod is released, the spring releases energy and pushes the baffle to pop out with the help of the support plate, which facilitates the collection of grain seeds.
[0014] In a preferred embodiment, the sliding plate is slidably connected to the sliding groove.
[0015] The beneficial effect of adopting the above-mentioned further solution is that pulling the first connecting rope causes the baffle to drive the sliding plate to slide along the sliding groove, thereby realizing the opening and closing control of the material receiving groove.
[0016] In a preferred embodiment, a drill bit is provided at the bottom of the support column.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, during use, pressure is applied by the handle to rotate the drill bit at the bottom of the support column and drill into the grain pile, thereby obtaining a grain sample for subsequent testing and analysis.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] 1. The support column accommodates the sampling assembly and inserts it into the grain pile through the bottom drill bit. In the sampling assembly, the baffle and the sliding plate cooperate. Under the action of the shrinking assembly, the sliding is achieved by the guide groove of the fixed rod and the sliding groove of the support plate. The spring sheet assists in the reset, thereby controlling the opening and closing of the material receiving groove on the support column, achieving the effect of layered sampling and preventing grain leakage.
[0020] 2. When in use, the operator manually pulls up the lifting rod located at the top of the handle. The first connecting rope on the connecting ring at the bottom of the lifting rod is tightened accordingly. The first connecting rope, through its connection with the sampling assembly, drives the relevant components to move, thereby controlling the opening and closing state of the material receiving slot on the support column.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a layered sampling mechanism for a grain seed sampler, comprising: a handle 1 and a support column 3 disposed at the bottom of the handle 1;
[0033] The sampling assembly 4 is placed inside the support column 3. The sampling assembly 4 includes a baffle 41 fixed inside the support column 3. A sliding plate 46 is provided inside the baffle 41. A support plate 42 is provided inside the support column 3. A sliding groove 45 is provided on the inner wall of the support plate 42. A spring piece 47 is provided at the bottom of the baffle 41 away from the sliding plate 46. A fixing rod 43 is provided at the top of the support plate 42. A guide groove 44 is provided on the fixing rod 43. The support column 3 accommodates the sampling assembly 4 and inserts it into the grain pile through the bottom drill bit 6. In the sampling assembly 4, the baffle 41 and the sliding plate 46 cooperate. Under the action of the shrinking assembly 2, the baffle 41 slides with the help of the guide groove 44 of the fixing rod 43 and the sliding groove 45 of the support plate 42. The spring piece 47 assists in resetting, thereby controlling the opening and closing of the receiving slot 5 on the support column 3, achieving the effect of layered sampling and preventing grain leakage.
[0034] Shrink assembly 2 is located on top of handle 1. Shrink assembly 2 includes a pull rod 21 fixed to the top of handle 1. A connecting ring 22 is provided at the bottom of pull rod 21. A first connecting rope 23 is provided on the connecting ring 22. A pull rod storage slot 24 is provided at the top of handle 1. When in use, the operator manually pulls up the pull rod 21 located at the top of handle 1. The first connecting rope 23 on the connecting ring 22 at the bottom of pull rod 21 is tightened accordingly. The first connecting rope 23 drives the relevant components to move through the connection with the sampling assembly 4, thereby controlling the opening and closing state of the material receiving slot 5 on the support column 3.
[0035] Furthermore, such as Figure 1 - Figure 4 As shown: The other end of the first connecting rope 23 away from the connecting ring 22 is connected to the baffle 41. By pulling the top lifting rod 21, the first connecting rope 23 drives the baffle 41 to retract through the guide groove 44, closing the material receiving slot 5 and preventing the internal material from falling out.
[0036] The above solutions also have the problem of difficulty in collecting grains, such as... Figure 1 - Figure 4 As shown: In this scheme, a spring plate 47 is provided at the bottom of the baffle 41. The other end of the spring plate 47 is connected to the support plate 42. When the lifting rod 21 is pulled to retract the baffle 41, the spring plate 47 is stretched and stores energy. After the lifting rod 21 is released, the spring plate 47 releases energy and pushes the baffle 41 out with the help of the support plate 42, which facilitates the collection of grain seeds.
[0037] Working principle: such as Figure 1 - Figure 4 As shown, handle 1 is the force application point of the entire operation. The operator applies pressure through it to make the drill bit 6 at the bottom of the support column 3 rotate and insert into the grain pile, creating conditions for sampling. The support column 3 not only provides a stable space for the internal sampling component 4, but its evenly spaced receiving slots 5 are also channels for the grain seeds to enter.
[0038] The sampling assembly 4 is the core component. The baffle 41 and sliding plate 46 work closely together, achieving precise movement under the action of the retraction assembly 2. When the operator manually pulls the lifting rod 21 at the top of the handle 1, the first connecting rope 23 on the bottom connecting ring 22 of the lifting rod 21 is tightened. The first connecting rope 23, through the guide groove 44 on the fixed rod 43, drives the baffle 41 to retract. At this time, the spring piece 47 at the bottom of the baffle 41 is stretched and stores energy. Simultaneously, the baffle 41 drives the sliding plate 46 to slide along the sliding groove 45 of the support plate 42, thereby closing the material collection slot 5 and effectively preventing the collected grain seeds from falling out and the same layer of grain from entering. When the target layer position is reached, the lifting rod 21 is released, the spring piece 47 releases energy, and through the connection with the support plate 42, pushes the baffle 41 to pop out, opening the material collection slot 5. The second connecting rope 25 can then drive the sampling assemblies 4 of different layers to operate, facilitating the entry of grain seeds into the sampling assembly 4 for collection.
[0039] The pull rod storage slot 24 in the shrinking component 2 provides storage space for the pull rod 21 after the operation is completed, which facilitates the storage and organization of the equipment, making the entire sampling process convenient and orderly, ensuring the accuracy and efficiency of stratified sampling, and the collected grain seeds can be used for subsequent testing and analysis, providing a reliable basis for grain quality assessment, etc.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
