Description

Technical Field

[0001] This utility model relates to the field of bio-based material sampling technology, and in particular to a bio-based new material sampling device. Background Technology

[0002] Bio-based materials refer to a new type of material manufactured using renewable biomass, specifically including grains, legumes, straw, bamboo and wood powder, and animal fur waste, through biological, chemical, and physical methods. Due to their excellent properties of being green, environmentally friendly, using renewable raw materials, and being biodegradable, they are widely used in fashion, home furnishings, outdoor products, and industrial applications, and are gradually moving towards large-scale industrial application and commercialization.

[0003] In existing technologies, when sampling and testing bio-based new materials, the samples may clump due to their structural composition. Existing samplers cannot break up and sieve the samples after sampling, and the clumped samples need to be broken up and sieved separately during testing, which affects the testing efficiency. Therefore, there is an urgent need for a bio-based new material sampling device that can break up and sieve the samples. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for bio-based new materials, which can break down and sieve the collected samples to ensure the quality of the samples and provide convenience for the testing operation.

[0005] The present invention adopts the following technical solution:

[0006] A sampling device for a novel bio-based material includes a sampling cylinder with a sampling hole at the top. A spiral conveying blade is rotatably disposed inside the sampling cylinder. A sieve cylinder is rotatably disposed at the bottom of the sampling cylinder at the end away from the sampling hole. The sieve cylinder is connected to the rotating rod on the spiral conveying blade via a transmission component. A sampling bottle is detachably connected to the sampling cylinder and sleeved on the outside of the sieve cylinder.

[0007] Preferably, the transmission component includes a driving bevel gear disposed on the rotating rod, a transmission rod disposed on the screen cylinder, and a driven bevel gear meshing with the driving bevel gear disposed at the top of the transmission rod.

[0008] Preferably, a protective cover is provided inside the sampling cylinder, and the protective cover is fitted over the outside of the driving bevel gear and the driven bevel gear.

[0009] Preferably, a support frame is provided inside the screen cylinder, and the transmission rod is fixedly connected to the support frame.

[0010] Preferably, a collection box is threaded at the bottom of the sieve cylinder.

[0011] Preferably, the rotating rod on the spiral conveying blade is connected to a motor located at the end of the sampling cylinder.

[0012] Preferably, the sampling cylinder has a receiving cavity at its end, and the motor is disposed within the receiving cavity.

[0013] Preferably, the sampling cylinder is threaded at its end with a cover plate that seals the accommodating cavity, and the cover plate is provided with a heat dissipation mesh.

[0014] Preferably, the accommodating cavity is provided with a storage battery connected to the motor, and the sampling cylinder is provided with a charging port connected to the storage battery.

[0015] Preferably, the front end of the sampling tube to the sampling hole is set as a slope that slopes from bottom to top.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the spiral conveying blades inside the sampling cylinder, this utility model can break up the agglomerated sample during the process of conveying the sample. After the sample enters the sieve cylinder, it will drive the sieve cylinder to rotate with the rotation of the spiral conveying blades, thereby realizing the sieving of the sample. In this process, it helps to further break up and disperse the sample to ensure the quality of the sample, thus providing favorable conditions for subsequent sample testing.

[0020] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 3As shown, the sampling device for a new bio-based material of this invention includes a sampling cylinder 1, which is cylindrical in shape. A sampling hole 2 is provided at the top of the sampling cylinder 1. The front end of the sampling cylinder 1, extending to the sampling hole 2, is sloped upwards, forming a pointed tip to facilitate insertion of the sampling cylinder 1 into the accumulated sample. A spiral conveying blade 3 is rotatably mounted inside the sampling cylinder 1. The spiral blade can be driven manually or by a motor. The spiral conveying blade 3 disperses the sample during transport, preventing clumping. The sampling cylinder 1... A sieve cylinder 4 is rotatably mounted at the bottom of the sampling cylinder 1, away from the sampling hole 2. The opening diameter of the sieve cylinder 4 matches the discharge port diameter at the bottom of the sampling cylinder 1 to ensure that the material falls smoothly into the sieve cylinder 4. The sieve cylinder 4 is connected to the rotating rod 5 on the screw conveyor blade 3 via a transmission component. During operation, the rotation of the screw conveyor blade 3 and the rotating rod 5 drives the sieve cylinder 4 to rotate synchronously via the transmission component, thereby achieving simultaneous screening and sampling operations. A sampling bottle 6 is detachably connected to the sampling cylinder 1 and fitted outside the sieve cylinder 4. The sampling bottle 6 is preferably made of a transparent material, specifically a transparent glass bottle or a plastic bottle, so as to intuitively observe the sampling process. The sampling bottle 6 is preferably detachably connected to the sampling cylinder 1 by threads. Specifically, a threaded head is provided at the top of the sampling bottle 6 and a threaded sleeve is provided at the bottom of the sampling cylinder 1. The sampling bottle 6 is installed and fixed at the bottom of the sampling cylinder 1 by the threaded connection between the threaded head and the threaded sleeve.

[0022] In addition, an operating handle 7 is provided at the end of the sampling cylinder 1 for easy gripping during use. A collection box 8 is threaded onto the bottom of the sieve cylinder 4, such as... Figure 3 As shown, the collection box 8 includes a collection part 8-1 at the bottom and a reduced-diameter connecting part 8-2 coaxially disposed at the top of the collection part 8-1. A temporary collection cavity 8-3 is formed between the collection part 8-1 and the connecting part 8-2. The collection box 8 is disposed at the bottom of the screen cylinder 4 through the thread on the outside of the connecting part 8-2. The collection box 8 facilitates the centralized cleaning of the collected materials inside the screen cylinder 4 without disassembling the screen cylinder 4, thus improving the convenience of operation.

[0023] Furthermore, in this embodiment, the transmission component includes a driving bevel gear 9 mounted on the rotating rod 5. A support frame, with a cross-shaped structure, is located inside the sieve cylinder 4, in the lower middle part of the sieve cylinder 4. The transmission rod 10 is fixedly connected to the support frame. A driven bevel gear 11, meshing with the driving bevel gear 9, is mounted on the top of the transmission rod 10. During operation, as the rotating rod 5 rotates, the driving bevel gear 9 meshes with the driven bevel gear 11, driving the sieve cylinder 4 to rotate, thereby completing the sample dispersing and sieving operation. This process traps severely agglomerated samples and large debris within the samples inside the sieve cylinder 4, while qualified samples enter the sampling bottle 6. In addition, a protective cover 12 is installed inside the sampling cylinder 1, covering the driving bevel gear 9 and the driven bevel gear 11. Bearings are installed at the connections between the rotating rod 5 and the transmission rod 10 and the protective cover 12 to ensure normal operation while providing support for the rotating rod 5 and the transmission rod 10. The protective cover 12 can prevent dust in the sample from falling onto the driving bevel gear 9 and the driven bevel gear 11, so as not to affect their normal transmission.

[0024] Furthermore, in this embodiment, the rotating rod 5 on the spiral conveying blade 3 is connected to the motor 13 located at the end of the sampling cylinder 1. Driving the spiral conveying blade 3 to rotate via the motor 13 improves the convenience of the sampling operation. Specifically, the sampling cylinder 1 has a receiving cavity 14 at its end, and the motor 13 is located within the receiving cavity 14. Additionally, a cover plate 15 is threaded onto the end of the sampling cylinder 1 to seal the receiving cavity 14, and a heat dissipation mesh 16 is provided on the cover plate 15. The cover plate 15 and the sampling cylinder 1 are preferably threaded together for easy disassembly and maintenance of the motor 13. Furthermore, a battery 17 connected to the motor 13 is located within the receiving cavity 14 to power the motor 13 during sampling, eliminating the need for an external power source, reducing wiring, and improving operational convenience. The sampling cylinder 1 has a charging port 18 connected to the battery 17 for periodic recharging of the battery 17.

[0025] In use, this invention first inserts the end of the sampling cylinder 1 into the sample to be collected. Then, the motor 13 is turned on. As the motor 13 rotates, the material falling into the sampling cylinder 1 from the sampling hole 2 is conveyed into the sieve cylinder 4. During this process, the material is initially dispersed through contact with the spiral conveyor blades 3. Then, as the sieve cylinder 4 rotates, the material is further dispersed through collision with the inner wall of the sieve cylinder 4, and is then sieved. Severely agglomerated samples that cannot be dispersed, as well as larger impurities in the sample, are retained in the sieve cylinder 4. The ejected material enters the sampling bottle 6 for collection. Finally, the sampling bottle 6 is removed, and the collected sample is poured out. This effectively ensures the quality of the sample and provides favorable conditions for the analysis of the material's composition and properties.
