Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a sampling inspection device for rice processing. Background Technology

[0002] Quality control is a crucial aspect of rice production. To ensure that the produced rice meets quality standards, manufacturers typically conduct random sampling inspections of the bagged rice. Sampling inspection is a method that involves randomly selecting samples from rice bags and then observing the samples to confirm whether the rice quality meets the prescribed standards.

[0003] Chinese patent document CN202323242269.4 discloses a rice sampling device. When used, a user opens a sealed plug and places a sample of rice into a storage bottle. The user can adjust the position of the limiting rod according to the required quantity of rice to be sampled, helping to quickly identify the volume of the sampled rice. The user can rotate the anti-slip cap, causing the lead screw to rotate and the screw sleeve to move vertically. This, in turn, drives the corresponding limiting rod to adjust its height via the connecting block and the limiting block. The user can obtain the appropriate quantity of rice by looking through the transparent plastic storage bottle and using a ruler in conjunction with the height of the limiting rod. Finally, the sample is sealed... The stopper ensures the sealing of the inner cavity of the storage bottle. The setting of the limiting rod makes it easy for personnel to see from top to bottom whether the amount of rice inside the storage bottle meets the sampling requirements. The outer shell protects its internal structure from external forces. The storage bottle is made of transparent plastic, and personnel can see the amount of rice inside through the outer wall of the storage bottle. The setting of the screw makes it easy for personnel to control the displacement direction of the screw sleeve. The setting of the anti-slip cap reduces the probability of the screw sleeve slipping when personnel turn it. The setting of the through groove, together with the connecting block, prevents the screw sleeve from rotating on its own. Through the structural design, personnel can quickly and accurately control the sampling quantity of rice during the sampling inspection process.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device's outer shell is rectangular with sharp edges and corners, and the limiting rod protrudes beyond the surface of the storage bottle. When the operator holds the device, their palm directly contacts the edges and corners of the outer shell and the protruding part of the limiting rod, creating stress concentration points. Especially during high-frequency sampling inspections, repeated pressure on the edges can easily lead to fatigue and even abrasions. The limiting rod is fixedly connected to the connecting block via a limiting block, and the bottom of the lead screw relies on a rotating shaft, while the top passes through the outer shell via a bushing. This fixed connection method results in a high degree of integration of the adjustment mechanism and cumbersome disassembly steps. When problems such as lead screw jamming or limiting rod wear occur after long-term use, it is necessary to remove the outer shell, separate the connecting block and the limiting block, and even disassemble the rotating shaft or bushing, consuming a lot of time and tools. Therefore, a sampling inspection device for rice processing is proposed to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a sampling inspection device for rice processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling inspection device for rice processing, comprising a storage bottle and a sealing plug, wherein a first arc-shaped block is provided on the storage bottle, a second arc-shaped block is rotatably mounted on the end of the first arc-shaped block, and a limit adjustment mechanism is provided on the storage bottle;

[0007] The limit adjustment includes setting a plug and a slot. The first arc-shaped block has a slot inside. The end of the second arc-shaped block is fixed with a plug that slides with the slot. The plug has a slot. A fixing box is fixed to the outside of the end of the first arc-shaped block. A plug rod is slidably installed in the fixing box. A baffle is fixed on the plug rod. A spring is sleeved on the plug rod. A locking block that engages with the slot is fixed on one side of the baffle.

[0008] Furthermore, the ends of both the card block and the insertion block are trapezoidal, and a through groove for the card block to slide is provided in the first arc-shaped block.

[0009] Furthermore, the two ends of the spring are respectively fixed to the side wall of the baffle and the bottom wall of the inner side of the fixed box.

[0010] Furthermore, both the first and second arc-shaped blocks are threaded with threaded rods, and a clamping block is rotatably mounted at the end of the threaded rod.

[0011] Furthermore, the inner sidewalls of both the first and second arc-shaped blocks are provided with storage grooves for storing the clamping blocks.

[0012] Furthermore, the limiting adjustment includes multiple grooves formed on the outside of the storage bottle, with a rubber pad fixed in the groove, the surface of the rubber pad being flush with the outside of the storage bottle.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This sampling inspection device for rice processing features a limit adjustment mechanism. The first and second arc-shaped blocks are quickly engaged via inserts, slots, and spring-driven locking blocks. Operators can adjust the height of the second arc-shaped block simply by pushing it. The threaded rods within the first and second arc-shaped blocks can extend the clamping block, adapting to storage bottles of different diameters or fixing it to the testing equipment. Rotating the threaded rods quickly locks the limit position, meeting the quantitative needs of diverse sampling scenarios. The sliding fit between the inserts and slots, and the separate design of the locking block and slot, allow for quick disassembly of the first and second arc-shaped blocks (simply press the insert to disengage the locking block from the slot), eliminating the need for tools to separate the limit adjustment mechanism. The wraparound structure formed by the first and second arc-shaped blocks conforms to the natural curvature of the palm, replacing the angular design of traditional rectangular shells. This ensures even pressure distribution in the palm during grip, preventing discomfort during prolonged operation, while the rubber pad further increases grip friction. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5 This embodiment of a sampling inspection device for rice processing includes a storage bottle 1 and a sealing plug 2. A first arc-shaped block 301 is provided on the storage bottle 1, and a second arc-shaped block 302 is rotatably mounted on the end of the first arc-shaped block 301. A limit adjustment mechanism 3 is provided on the storage bottle 1, and scale lines are provided on the outer side of the storage bottle 1.

[0023] The limit adjustment includes setting a plug 309 and a slot 311. The slot 311 is opened inside the first arc-shaped block 301. The end of the second arc-shaped block 302 is fixed with a plug 309 that slides with the slot 311. The plug 309 is provided with a slot 310. A fixing box 303 is fixed to the outer side of the end of the first arc-shaped block 301. A plug rod 308 is slidably installed in the fixing box 303. A baffle 313 is fixed on the plug rod 308. A spring 314 is sleeved on the plug rod 308. A locking block 312 that engages with the slot 310 is fixed on one side of the baffle 313.

[0024] The inner sidewalls of the first arc-shaped block 301 and the second arc-shaped block 302 are provided with storage slots 315 for storing the clamping block 305.

[0025] The limit adjustment includes multiple grooves 307 on the outside of the storage bottle 1. A rubber pad 306 is fixed in the groove 307. The anti-slip structure of the rubber pad 306 improves the stability and comfort when holding the bottle and reduces operating fatigue. The surface of the rubber pad 306 is flush with the outside of the storage bottle 1. A storage groove 315 is opened on the inner wall of the arc-shaped block. When the clamping block 305 retracts with the threaded rod 304, it is completely embedded in the storage groove 315, so that the inner wall of the arc-shaped block remains flat.

[0026] The operator pushes the second arc-shaped block 302 to rotate around the rotating connection point, causing the insert block 309 to insert into the slot 311 of the first arc-shaped block 301. The trapezoidal end of the insert block 309 presses against the locking block 312, forcing the locking block 312 to retract into the fixed box 303 against the force of the spring 314. When the insert block 309 is fully inserted into the slot 311, the locking block 312 aligns with the slot 310 of the insert block 309, and the spring 314 resets, pushing the locking block 312 into the slot 310, fixing the first and second arc-shaped blocks 302 into one unit, forming a ring-shaped limiting position for the storage bottle 1. Conversely, pulling the insert rod 308 causes the baffle 313 and the locking block 312 to retract, releasing the locking block 312 from the slot 310, allowing the second arc-shaped block 302 to be rotated to adjust the limiting position.

[0027] Both the locking block 312 and the insert block 309 have trapezoidal ends. The first arc-shaped block 301 has a through groove for the locking block 312 to slide. The trapezoidal structure can guide the locking block 312 to automatically align when the insert block 309 is inserted. The through groove provides a sliding guide for the locking block 312, ensuring a smooth and uninterrupted locking process. When the trapezoidal end of the insert block 309 contacts the locking block 312, the inclined surface generates a horizontal component force, pushing the locking block 312 to slide along the through groove into the fixing box 303. No manual alignment is required, reducing the difficulty of operation. When the insert block 309 is in place, the locking block 312 pops out along the through groove under the force of the spring 314. The trapezoidal locking block 312 and the inclined surface of the locking groove 310 fit tightly together, eliminating the fit gap and ensuring that the limiting position is stable and does not loosen.

[0028] Meanwhile, the two ends of the spring 314 are fixed to the side wall of the baffle 313 and the inner bottom wall of the fixed box 303 respectively. The elastic reset structure driven by the spring 314 ensures the stable engagement of the card block 312 and the card slot 310, and avoids accidental unlocking.

[0029] In addition, threaded rods 304 are threadedly connected to both the first arc-shaped block 301 and the second arc-shaped block 302. A clamping block 305 is rotatably installed at the end of the threaded rod 304. The position of the clamping block 305 can be adjusted by adjusting the threaded rod 304 to clamp and fix the storage bottle 1 or adapt it to external devices, thus expanding the application scenarios of the device.

[0030] The working principle of the above embodiments is as follows:

[0031] When in use, personnel open the sealing plug 2 and then put the sampled rice into the storage bottle 1. Personnel can adjust the position of the first arc block 301 and the second arc block 302 according to the actual amount of rice to be sampled, which helps personnel quickly identify the volume of the sampled rice.

[0032] The operator holds the storage bottle 1 and pushes the second arc-shaped block 302 around its rotational connection point with the first arc-shaped block 301 with their thumb. This aligns the insert 309 at the end of the second arc-shaped block 302 with the slot 311 inside the first arc-shaped block 301. When the trapezoidal end of the insert 309 contacts the locking block 312 inside the outer fixing box 303 of the first arc-shaped block 301, the inclined surface pushes the locking block 312 to slide along the through groove into the fixing box 303. When the insert 309 is fully inserted into the slot 311 and the locking block 312 aligns with the locking groove 310 of the insert 309, the spring 314 returns to its original position, releasing its elastic force and pushing the baffle 313 and the locking block 312 into the locking groove 310, thus fixing the first and second arc-shaped blocks 302 together to form a circumferential limiting position for the storage bottle 1. At this time, the position of the arc-shaped block corresponds to the sampling volume scale on the storage bottle 1.

[0033] In conjunction with the rotating threaded rods 304 within the first and second arc-shaped blocks 302, the clamping block 305 at the drive end extends from the storage groove 315. The anti-slip texture or flexible material on the surface of the clamping block 305 adheres to the rubber pad 306 on the outer wall of the storage bottle 1, achieving secondary reinforcement through the self-locking force of the threads. There are no protruding parts on the outer side of the arc-shaped blocks, avoiding the risk of hand wear caused by the protrusion of traditional outer shells.

[0034] When cleaning or replacement of parts is required, pull the insert rod 308 on the outside of the fixed box 303. This will cause the baffle 313 and the locking block 312 to retract against the force of the spring 314, releasing the locking block 312 from the locking slot 310 of the insert block 309. At this time, the second arc-shaped block 302 can be rotated directly to separate the insert block 309 from the slot 311. The arc-shaped block assembly can be disassembled without tools to clean the accumulated rice dust or replace the worn spring 314 and locking block 312.
