Description

Technical Field

[0001] This utility model relates to the technical field of agricultural product testing and sampling, and in particular to a sampling device with a grinding and crushing structure. Background Technology

[0002] In agricultural production, it is necessary to conduct relevant heavy metal testing on agricultural products to ensure that they meet the food safety and hygiene standards.

[0003] When testing agricultural products for heavy metals, it is usually necessary to crush and grind the products before sampling. In the prior art, a utility model patent with publication number CN219810723U discloses a heavy metal sample sampling device. This device includes a base, a centrifuge chamber, a water tank, a water tank cover, and a centrifuge chamber cover. A locking groove is fixedly connected to the top of the base, and the water tank is locked to the locking groove. The centrifuge chamber contains a centrifuge chamber, and the top of the water tank is threadedly connected to the water tank cover. The top of the centrifuge chamber is threadedly connected to the centrifuge chamber cover. The centrifuge chamber contains a crushing mechanism. By using a grinding blade with a diverting block, a cutting blade group, an impact blade group, and a grinding blade group, along with a centrifugal motor, the sample can be thoroughly ground and crushed through forward and reverse rotation, improving operational efficiency. By incorporating an ultrasonic probe, the plant cell walls in the agricultural products can be effectively broken down, further thoroughly crushing the sample and improving detection efficiency and accuracy.

[0004] Although the heavy metal sample sampling device in the aforementioned patented technology can effectively crush and grind agricultural product samples and improve detection accuracy, it still has the following drawbacks: the funnel connected to the water tank cover is not covered, and when not in use, the funnel is in an open state for a long time, which makes it easy for external debris and dust to enter the water tank through the funnel, causing the water tank to become dirty and its practicality is insufficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sampling device with a grinding and crushing structure that can close the funnel when the device is not in use, thus preventing the funnel from being in an open state for a long time, preventing external debris and dust from entering the water storage tank through the funnel, preventing the water storage tank from becoming dirty, and improving the practicality of the device.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling device with a grinding and crushing structure, comprising a base, a sealing assembly, and a locking assembly. A water storage tank is fitted onto the top of the base, and a water storage tank cover is threaded onto the top of the water storage tank. A funnel is connected to the water storage tank cover. The sealing assembly includes an end cap, on the outer wall of which two sets of positioning blocks are symmetrically fixedly connected. The positioning blocks are integrally formed with the end cap. A docking ring is fixedly connected to the top of the funnel. Two sets of positioning grooves are symmetrically formed on the top of the docking ring. The end cap is mounted on the docking ring through the cooperation of the positioning blocks and the positioning grooves. The top of the end cap is connected to the docking ring. The top of the ring is aligned, and a spiral connecting ring is rotatably sleeved on the positioning block on the rear side of the end cap. A rear connecting plate is fixedly connected to the upper side of the rear end of the funnel, and the spiral connecting ring is rotatably mounted on the rear connecting plate. The locking assembly includes a spiral locking ring, which is rotatably mounted on the positioning block on the front side of the end cap. A front connecting plate is fixedly connected to the upper side of the front end of the funnel. A sliding plate is slidably provided on the front connecting plate, and a locking seat is fixedly connected to the bottom end of the sliding plate. Two sets of springs are symmetrically fixedly connected between the top of the locking seat and the bottom end of the front connecting plate. A U-shaped groove is opened at the bottom end of the locking seat, and the spiral locking ring is locked in the U-shaped groove under the action of the spring.

[0008] Preferably, an annular sealing platform is fixedly connected to the inner wall of the docking ring, and a sealing ring is fixedly connected to the bottom edge of the end cap.

[0009] Preferably, a limiting plate is fixedly connected to the top of the skateboard.

[0010] Preferably, a fastening rubber sleeve is fixedly fitted on the outer wall of the loop locking ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is not in use, by rotating the end cap, the end cap is installed on the docking ring, sealing the funnel. With the cooperation of the positioning block and the positioning groove, the end cap is positioned to prevent it from wobbling left and right. Then, by rotating the loop locking ring, the loop locking ring is engaged in the U-shaped groove at the bottom of the locking seat. During this process, the loop locking ring squeezes the locking seat, causing the locking seat to push the slide plate upward, thereby compressing the spring. When the loop locking ring is engaged in the U-shaped groove, the spring rebound generates a downward thrust, causing the locking seat to be tightly fastened to the loop locking ring. This causes the loop locking ring to pull the positioning block downward, thus ensuring that the end cap is securely placed on the docking ring and preventing the end cap from opening on its own. This prevents the funnel from being in an open state for a long time when the device is not in use, preventing external debris and dust from entering the water storage tank through the funnel, avoiding dirt accumulation in the water storage tank, and improving practicality.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example

[0020] Please see Figures 1-5This utility model discloses a sampling device with a grinding and crushing structure, comprising a base 1, an end cap 5, and a U-shaped locking ring 10. A water storage tank 2 is fitted onto the top of the base 1, and a water storage tank cover 3 is threaded onto the top of the water storage tank 2. A funnel 4 is connected to the water storage tank cover 3. Two sets of positioning blocks 6 are symmetrically fixedly connected to the outer wall of the end cap 5, and the positioning blocks 6 are integrally formed with the end cap 5. A docking ring 7 is fixedly connected to the top of the funnel 4, and two sets of positioning grooves are symmetrically formed on the top of the docking ring 7. The end cap 5 is mounted on the docking ring 7 through the cooperation of the positioning blocks 6 and the positioning grooves. The top of the end cap 5 is aligned with the top of the docking ring 7. A loop-shaped connecting ring 8 is rotatably sleeved on the positioning block 6 on the rear side of the end cap 5. A rear connecting plate 9 is fixedly connected to the upper rear end of the funnel 4. The loop-shaped connecting ring 8 is rotatably mounted on the rear connecting plate 9. A loop-shaped locking ring 10 is rotatably mounted on the positioning block 6 on the front side of the end cap 5. A front connecting plate 11 is fixedly connected to the upper front end of the funnel 4. A sliding plate 12 is slidably mounted on the front connecting plate 11. A locking seat 13 is fixedly connected to the bottom end of the sliding plate 12. Two sets of springs 14 are symmetrically fixedly connected between the top end of the locking seat 13 and the bottom end of the front connecting plate 11. The bottom of the locking seat 13 has a U-shaped groove 15. The retaining ring 10 is engaged in the U-shaped groove 15 under the action of the spring 14. When the device is not in use, the end cover 5 is rotated and placed on the docking ring 7 to seal the funnel 4. With the cooperation of the positioning block 6 and the positioning groove, the end cover 5 is positioned to prevent it from wobbling from side to side. Then, by rotating the retaining ring 10, the retaining ring 10 is engaged in the U-shaped groove 15 at the bottom of the locking seat 13. During this process, the retaining ring 10 presses against the locking seat 13, causing the locking seat 13 to push. The slide plate 12 slides upward, which in turn compresses the spring 14. When the loop locking ring 10 is engaged in the U-shaped slot 15, the spring 14 rebounds and generates a downward thrust, causing the locking seat 13 to be tightly fastened to the loop locking ring 10. This causes the loop locking ring 10 to pull down the positioning block 6, thereby ensuring that the end cover 5 is securely placed on the docking ring 7 and preventing the end cover 5 from opening on its own. This prevents the funnel from being in an open state for a long time when the device is not in use, preventing external debris and dust from entering the water storage tank through the funnel, avoiding the water storage tank from becoming dirty, and improving practicality.

[0021] An annular sealing platform 17 is fixedly connected to the inner wall of the docking ring 7, and a sealing ring 18 is fixedly connected to the bottom edge of the end cover 5. By setting the annular sealing platform 17 and the sealing ring 18, when the end cover 5 is closed, the sealing ring 18 tightly abuts against the annular sealing platform 17. Through the cooperation of the annular sealing platform 17 and the sealing ring 18, the sealing performance of the end cover 5 when closed can be effectively improved.

[0022] The top of the slide plate 12 is fixedly connected to a limiting plate 16; when the end cover 5 is opened, the spring 14 rebounds and causes the slide plate 12 to slide downward. The limiting plate 16 set at the top of the slide plate 12 can prevent the slide plate 12 from detaching from the front connecting plate 11.

[0023] A fastening sleeve 19 is fixedly sleeved on the outer wall of the spiral locking ring 10; by setting the fastening sleeve 19, the spiral locking ring 10 can be more securely engaged with the U-shaped slot 15 when it is inserted into the U-shaped slot 15.

[0024] This utility model discloses a sampling device with a grinding and crushing structure. Its working principle is as follows: When the device is not in use, rotating the end cap 5 places it onto the docking ring 7, sealing the funnel 4. With the cooperation of the positioning block 6 and the positioning groove, the end cap 5 is positioned to prevent lateral movement. Then, rotating the loop-shaped locking ring 10 causes it to engage in the U-shaped groove 15 at the bottom of the locking seat 13. During this process, the loop-shaped locking ring 10 presses against the locking seat 13, causing the locking seat 13 to push the slide plate 12 upwards, thereby compressing the spring 14. When the loop-shaped locking ring 10 engages in the U-shaped groove 15, the spring 14 rebounds, generating a downward thrust that tightly engages the locking seat 13 with the loop-shaped locking ring 10. This causes the loop-shaped locking ring 10 to pull the positioning block 6 downwards. This ensures that the end cap 5 is securely placed on the docking ring 7, preventing the end cap 5 from opening on its own. When the device is not in use, the funnel 4 is closed. When the device needs to be used, the locking seat 13 is pushed upward to disengage the U-shaped locking ring 10 from the U-shaped slot 15. Then, the end cap 5 is opened by rotating the U-shaped locking ring 10, allowing water to be added to the water tank 2 through the funnel 4. The base 1, water tank 2, water tank cover 3, and funnel 4 in this utility model are all referenced from a heavy metal sample sampling device with patent publication number CN219810723U, which belongs to the published prior art. Its specific structure and working principle have been described in detail in the published patent. This application only references its function and does not modify its structure. Therefore, it will not be described in detail here.

[0025] The sampling device with a grinding and crushing structure of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
