Description

Technical Field

[0001] This utility model relates to the field of flour testing technology, and in particular to a flour sampling device for flour testing. Background Technology

[0002] Flour is a powdery substance made from wheat. Based on the protein content, flour can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour is a staple food in most parts of northern China, and there are many varieties of food made from flour, with diverse styles and flavors. During the transportation and use of flour, it is necessary to test its quality. This requires the use of sampling devices to collect the flour to be tested. The sampling device is a device that takes the material to be tested out of the process pipeline or container and transports it to the testing instrument.

[0003] In the prior art, such as Chinese Patent CN 221840774 U, a flour sampling device for flour testing includes a sampling cylinder. A rotating shaft is rotatably mounted inside the sampling cylinder, and spiral blades are fixedly mounted on the shaft. A motor is fixedly mounted at the top of the sampling cylinder, and the motor's output end is fixedly connected to the rotating shaft. A crushing blade is fixedly mounted near the bottom of the rotating shaft. A pointed cone extends from the bottom of the rotating shaft out of the sampling cylinder and is fixedly mounted thereon. A discharge pipe is fixedly mounted on the upper end of the outer wall of the sampling cylinder. The discharge pipe is a curved pipe, and an outlet communicating with the discharge pipe is opened on the side wall of the sampling cylinder. A collection bottle is located at the bottom of the discharge pipe. By inserting the bottom of the sampling cylinder into the flour to be sampled, the motor drives the rotating shaft and spiral blades to rotate. Simultaneously, the rotating shaft drives multiple crushing blades to rotate, breaking up clumps of flour and improving flour collection efficiency, reducing subsequent flour crushing. The rotation of the spiral blades moves the flour upwards within the sampling cylinder, facilitating sampling. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the patent breaks down the flour clumps in the flour with multiple crushing blades to improve flour collection efficiency and reduce subsequent crushing of the flour, the sampling tube needs to be manually inserted into the flour pile, which depends on the strength of the operator. When sampling from deep storage bins, flour pools, etc., it may be difficult to insert the tube or the sampling depth may be insufficient, resulting in a lack of representativeness of the sample. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the existing technology, the sampling tube needs to be manually inserted into the flour pile, which depends on the strength of the operator. When sampling from deep storage bins, flour pools, etc., it may be difficult to insert the tube or the sampling depth may be insufficient. Therefore, this invention proposes a flour sampling device for flour testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flour sampling device for flour detection, comprising an adjusting seat, an mounting plate fixedly installed at the bottom of the adjusting seat, two mounting holes through the top of the mounting plate, a first threaded rod rotatably installed inside the adjusting seat, a second motor fixedly installed at the top of the adjusting seat, the output end of the second motor fixedly connected to the top of the first threaded rod, a sliding plate threadedly connected to the outer wall of the first threaded rod, an opening through the outer wall of the sliding plate, a limiting groove formed on the inner wall of the opening, a spring fixedly installed on the inner wall of the limiting groove, a locking block fixedly installed at one end of the spring, a connecting rod fixedly installed on the outer wall of the locking block, a pull plate fixedly installed at one end of the connecting rod through the sliding plate, an extension plate slidably installed inside the opening, a plurality of evenly distributed locking slots formed on the outer wall of the extension plate, and a housing fixedly installed at one end of the extension plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, during use, the worker passes the bolt through the mounting hole to fix the mounting plate to the outer wall of the container, and then pulls the pull plate. The pull plate drives the locking block to leave the slot through the connecting rod, and the spring is compressed. Then, the housing is pulled, and the extension plate moves along the opening until the housing moves above the flour to be sampled. At this time, the worker releases the pull plate, and the spring force pushes the locking block into the slot, and the extension plate is fixed. Finally, the worker starts the second motor, and the output end of the second motor drives the first threaded rod to rotate, causing the sliding plate to descend, thereby driving the housing into the flour.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figures 1-5 As shown, this utility model provides a flour sampling device for flour detection, including an adjusting seat 7. An mounting plate 13 is fixedly installed at the bottom of the adjusting seat 7. Two mounting holes 14 are opened through the top of the mounting plate 13. A first threaded rod 15 is rotatably installed inside the adjusting seat 7. A second motor 16 is fixedly installed at the top of the adjusting seat 7. The output end of the second motor 16 is fixedly connected to the top of the first threaded rod 15. A sliding plate 17 is threadedly connected to the outer wall of the first threaded rod 15. An opening 18 is opened through the outer wall of the sliding plate 17. A limiting groove 20 is opened in the inner wall of the opening 18. A spring 21 is fixedly installed in the inner wall of the limiting groove 20. A locking block 22 is fixedly installed at one end of the spring 21. A connecting rod 23 is fixedly installed on the outer wall of the locking block 22. One end of the connecting rod 23 passes through the sliding plate 17 and is fixedly installed with a pull plate 24. An extension plate 8 is slidably installed inside the opening 18. A plurality of evenly distributed locking grooves 19 are opened on the outer wall of the extension plate 8. A housing 1 is fixedly installed at one end of the extension plate 8.

[0028] The overall effect of Embodiment 1 is as follows: In use, the operator passes the bolt through the mounting hole 14 to fix the mounting plate 13 to the outer wall of the container, and then pulls the pull plate 24. The pull plate 24 drives the locking block 22 away from the slot 19 through the connecting rod 23. The spring 21 is compressed, and then the housing 1 is pulled. The extension plate 8 moves along the opening 18 until the housing 1 moves above the flour to be sampled. At this time, the operator releases the pull plate 24. The elastic force of the spring 21 pushes the locking block 22 into the slot 19, and the extension plate 8 is fixed. Finally, the operator starts the second motor 16. The output end of the second motor 16 drives the first threaded rod 15 to rotate, causing the slide plate 17 to descend, thereby driving the housing 1 into the flour. There is no need to manually insert the housing 1 into the flour pile, which is convenient for insertion.

[0029] Example 2, as Figures 1-5 As shown, further, two fixing plates 2 are fixedly installed on the outer wall of the shell 1. An electric telescopic rod 3 is fixedly installed on the top of each of the two fixing plates 2. The telescopic end of the electric telescopic rod 3 passes through the fixing plate 2 and is fixedly installed with a lifting plate 4. A connecting plate 5 is fixedly installed between the two lifting plates 4.

[0030] Furthermore, two slots 26 are provided at the bottom of the connecting plate 5, and a fixing groove 27 is provided between the lifting plate 4 and the connecting plate 5. A threaded hole 28 is provided through the inner wall of the fixing groove 27. A second threaded rod 29 is threadedly connected inside the threaded hole 28. A handle 30 is fixedly installed at one end of the second threaded rod 29, and a connecting block 31 is movably connected to the other end of the second threaded rod 29 away from the handle 30.

[0031] Furthermore, insert plates 32 are slidably installed inside both slots 26, and connecting grooves 33 are provided on the outer wall of the insert plates 32. Drill bits 34 are fixedly installed at the bottom of the two insert plates 32.

[0032] Furthermore, a first motor 9 is fixedly installed on the top of the housing 1. The output end of the first motor 9 enters the housing 1 and a rotating shaft 10 is fixedly installed thereon. A spiral blade 11 is fixedly installed on the outer wall of the rotating shaft 10.

[0033] Furthermore, multiple evenly distributed blades 12 are fixedly installed on the outer wall of the rotating shaft 10 to break up the lumps in the flour, improve the flour collection efficiency, and reduce the subsequent crushing process of the flour.

[0034] Furthermore, a discharge pipe 6 is installed through and fixedly mounted on the outer wall of the shell 1.

[0035] Furthermore, a limiting plate 25 is fixedly installed at the end of the extension plate 8 away from the housing 1 to prevent the extension plate 8 from completely leaving the opening 18.

[0036] Furthermore, the outer wall of the connecting block 31 fits against the inner wall of the fixing groove 27 to prevent the connecting block 31 from rotating when the second threaded rod 29 rotates.

[0037] Furthermore, the outer wall of the extension plate 8 fits against the inner wall of the opening 18, and the outer wall of the locking block 22 fits against the inner wall of the slot 19. When the locking block 22 enters the slot 19, the extension plate 8 can be fixed in place.

[0038] The overall effect of Embodiment 2 is that when the shell 1 enters the flour pile, the drill bit 34 contacts the flour, making it easier for the shell 1 to enter the flour. The top of the connecting plate 5 is attached to the bottom of the shell 1 to prevent flour at other depths from entering the shell 1 before the bottom of the shell 1 reaches the required sampling position, thus affecting the detection. When the required sampling position is reached, the operator starts the electric telescopic rod 3. The telescopic end of the electric telescopic rod 3 is extended, and the connecting plate 5 leaves the bottom of the shell 1. At this time, the flour can enter the shell 1. The operator starts the first motor 9, the rotating shaft 10 rotates, and the flour rises along the spiral blades 11 and finally leaves from the discharge pipe 6, which facilitates sampling.

[0039] Working principle: In use, the operator passes the bolt through the mounting hole 14 to fix the mounting plate 13 to the outer wall of the container. Then, the operator pulls the pull plate 24. The pull plate 24 drives the locking block 22 away from the slot 19 through the connecting rod 23. The spring 21 is compressed, and then the operator pulls the housing 1. The extension plate 8 moves along the opening 18 until the housing 1 moves above the flour to be sampled. At this time, the operator releases the pull plate 24. The elastic force of the spring 21 pushes the locking block 22 into the slot 19, and the extension plate 8 is fixed. Finally, the operator starts the second motor 16. The output end of the second motor 16 drives the first threaded rod 15 to rotate, causing the slide plate 17 to descend, thereby driving the housing 1 into the flour. There is no need for manual insertion of the housing 1 into the flour pile, which is convenient for insertion. When the housing 1 enters the flour pile, the drill bit 34 contacts the flour, facilitating the entry of the housing 1 into the flour. The top of the connecting plate 5 fits snugly against the bottom of the housing 1, preventing flour from other depths from entering the housing 1 before the bottom reaches the required sampling position, thus avoiding interference with the testing. When the required sampling position is reached, the operator activates the electric telescopic rod 3. The telescopic end of the electric telescopic rod 3 extends, and the connecting plate 5 moves away from the bottom of the housing 1, allowing the flour to enter. The operator then activates the first motor 9, causing the shaft 10 to rotate. The flour rises along the spiral blades 11 and finally exits from the discharge pipe 6, facilitating sampling. When changing the drill bit 34, the operator rotates the two handles 30, which drive the second threaded rod 29 to rotate, causing it to move along the threaded hole 28. This, in turn, moves the connecting block 31 away from the connecting groove 33. The operator can then remove the insert plate 32, replace the new drill bit 34, insert the insert plate 32 into the slot 26, and reverse the rotation of the handles 30, allowing the connecting block 31 to enter the connecting groove 33. This completes the installation, improving installation efficiency.

[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.
