Description

Technical Field

[0001] This utility model relates to the field of grain sampling machine technology, and in particular to a pneumatic sampling head for grain sampling in containers. Background Technology

[0002] In the field of grain trade and storage, containers are widely used as an efficient and convenient mode of transportation for cross-border and cross-regional grain transport. However, the quality of grain inside containers is often affected by a variety of factors, such as humidity, temperature, pests, and storage time. These factors may lead to a decline in grain quality and even food safety issues. Regular and accurate sampling and testing of grain inside containers has become an important means of ensuring grain quality and safety. Therefore, a pneumatic sampling head for sampling grain in containers is needed.

[0003] A pneumatic sampling head for container grain sampling is a device component specifically designed for grain sampling inside containers. Traditional grain sampling methods mostly rely on manual operation, such as using tools like shovels and spoons for manual sampling. At the same time, some sampling heads may have design flaws, such as unreasonable flow channel design or inaccurate pressure regulation mechanisms. These design flaws may cause the sampling head to perform poorly in controlling the grain flow rate and fail to achieve the expected results. Furthermore, it cannot provide flexible control of the grain flow rate when facing different types of grain or different sampling needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pneumatic sampling head for container grain sampling, which aims to improve the limitations of traditional grain sampling heads in controlling the flow rate of grain into the sampler.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A pneumatic sampling head for grain sampling in containers includes a support shell, a protective shell fixedly connected to the inner wall of the support shell, a connecting cylinder fixedly connected to the outer wall of the protective shell, a support block fixedly connected to the outer wall of the connecting cylinder, a motor fixedly connected to the outer wall of the support block, a spur gear fixedly mounted on the output end of the motor, a half gear meshing with the tooth end of the spur gear, a first cylindrical block fixedly connected to the outer wall of the half gear, a first feed inlet inside the first cylindrical block, a second cylindrical block rotatably connected to the outer wall of the first cylindrical block, a second feed inlet inside the second cylindrical block, a connecting hopper fixedly connected to the outer wall of the second cylindrical block, the outer wall of the connecting hopper fixedly connected to the inner wall of the connecting cylinder, the outer wall of the half gear slidably connected to the interior of the connecting cylinder and the second cylindrical block, and a support assembly provided on the outer wall of the connecting hopper for auxiliary sampling.

[0006] Preferably, the support assembly includes a connecting ring, the inner wall of which is fixedly connected to the outer wall of the connecting hopper, a sampling cylinder is fixedly connected to the outer wall of the connecting ring, and the inner wall of the sampling cylinder is fixedly connected to the outer wall of the support shell.

[0007] Preferably, a connecting block is fixedly connected to the bottom end of the connecting cylinder, and a fixing cylinder is fixedly connected inside the connecting block.

[0008] Preferably, a limiting ring is fixedly connected to the inner wall of the fixed cylinder, and a locking block is slidably connected to the inner wall of the limiting ring.

[0009] Preferably, a card is fixedly connected to the outer wall of the card block.

[0010] Preferably, the outer wall of the card is slidably connected to the inner wall of the fixed cylinder.

[0011] Preferably, a spring is fixedly connected to the outer wall of the card.

[0012] Preferably, the outer wall of the spring is slidably connected to the inner wall of the fixed cylinder.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the half gear to slide in the connecting cylinder and the second cylindrical block through the sprocket, and then drives the first cylindrical block to slide on the second cylindrical block through the half gear. When the first feed port and the second feed port are aligned, the sampled grain can flow from the sampling cylinder into the support shell and then enter the sampler, thus achieving the effect of controlling the grain to enter the sampler.

[0014] 2. In this utility model, the connector squeezes the locking block to make it slide on the limiting ring. Then, the locking block squeezes the spring through the card to make it contract. Under the spring's rebound, the locking block can be locked on the connector of the sampling machine, achieving the effect of quick installation on the sampling machine, thereby reducing the time required to replace or adjust the sampling head.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a pneumatic sampling head for grain sampling in containers, comprising a support shell 1, a protective shell 2 fixedly connected to the inner wall of the support shell 1, a connecting cylinder 3 fixedly connected to the outer wall of the protective shell 2, a support block 4 fixedly connected to the outer wall of the connecting cylinder 3, a motor 5 fixedly connected to the outer wall of the support block 4, a spur gear 6 fixedly mounted at the output end of the motor 5, a half gear 7 meshing with the tooth end of the spur gear 6, a first cylindrical block 8 fixedly connected to the outer wall of the half gear 7, a first feed inlet 9 opened inside the first cylindrical block 8, and a second cylindrical block rotatably connected to the outer wall of the first cylindrical block 8. 11. A second feed inlet 12 is provided inside the second cylindrical block 11. A connecting hopper 10 is fixedly connected to the outer wall of the second cylindrical block 11. The outer wall of the connecting hopper 10 is fixedly connected to the inner wall of the connecting cylinder 3. The outer wall of the half gear 7 is slidably connected to the connecting cylinder 3 and the interior of the second cylindrical block 11. A support assembly is provided on the outer wall of the connecting hopper 10. The support assembly is used to assist sampling. The support assembly includes a connecting ring 13. The inner wall of the connecting ring 13 is fixedly connected to the outer wall of the connecting hopper 10. A sampling cylinder 14 is fixedly connected to the outer wall of the connecting ring 13. The inner wall of the sampling cylinder 14 is fixedly connected to the outer wall of the support shell 1.

[0019] Specifically, the support block 4 supports and fixes the motor 5, while the protective shell 2 protects the motor 5, the spur gear 6, and the half gear 7 from the influence of sampling. The motor 5 drives the spur gear 6 to rotate, which in turn drives the half gear 7 to slide within the connecting cylinder 3 and the second cylindrical block 11. The connecting cylinder 3 and the second cylindrical block 11 limit the movement of the half gear 7, which in turn drives the first cylindrical block 8 to slide along the inner wall of the second cylindrical block 11. When the first cylindrical block 8 rotates to align the first feed inlet 9 and the second feed inlet 12, the sampled grain flows from the sampling cylinder 14 through the first feed inlet 9 and the second feed inlet 12 into the support shell 1, thus controlling the grain entering the sampler. This effective grain entry control prevents potential blockages or overflows during sampling, which not only helps maintain a clean and safe working environment but also reduces grain waste and loss.

[0020] Reference Figure 3 A connecting block 15 is fixedly connected to the bottom end of the connecting cylinder 3, and a fixing cylinder 16 is fixedly connected inside the connecting block 15.

[0021] Specifically, the connecting cylinder 3 serves to support and fix the connecting block 15, and the connecting block 15 serves to connect and limit the fixing cylinder 16.

[0022] Reference Figure 3 and Figure 4 A limiting ring 17 is fixedly connected to the inner wall of the fixed cylinder 16, and a locking block 18 is slidably connected to the inner wall of the limiting ring 17; a card 19 is fixedly connected to the outer wall of the locking block 18; the outer wall of the card 19 is slidably connected to the inner wall of the fixed cylinder 16; a spring 20 is fixedly connected to the outer wall of the card 19; the outer wall of the spring 20 is slidably connected to the inner wall of the fixed cylinder 16.

[0023] Specifically, when the sampling head is installed, the connecting block 15 serves to install the entire assembly onto the connector of the sampling machine. At this time, the connector will press the locking block 18 to slide on the limiting ring 17, where the limiting ring 17 serves to limit the locking block 18. The locking block 18, through the card 19, compresses the spring 20 to cause it to contract. Under the rebound action of the spring 20, the locking block 18 is thus locked onto the connector of the sampling machine.

[0024] Working principle: When the sampling head is needed, first hold the support shell 1. The entire assembly can be installed onto the connector of the sampling machine via the connecting block 15. At this time, the connector will press the locking block 18, causing it to slide on the limiting ring 17. The locking block 18, through the card 19, will compress the spring 20, causing it to retract. The spring 20's rebound will then lock the locking block 18 onto the connector of the sampling machine. The motor 5 drives the sprocket 6 to rotate, which in turn drives the half-gear 7 to slide within the connecting cylinder 3 and the second cylindrical block 11. The half-gear 7 then drives the first cylindrical block 8 within the second cylindrical block... The inner wall of sampling cylinder 11 slides, and when the first cylindrical block 8 rotates to align the first feed inlet 9 and the second feed inlet 12, the sampled grain can flow from the sampling cylinder 14 through the first feed inlet 9 and the second feed inlet 12 into the support shell 1, and then into the sampling machine. This sampling head not only achieves the effect of quick installation on the sampling machine, thus reducing the time required for replacing or adjusting the sampling head and improving the overall efficiency of the sampling work, but also achieves the effect of controlling the grain entering the sampling machine, thereby ensuring the representativeness and consistency of each sample and improving the accuracy of the sampling. This is crucial for the assessment and monitoring of grain quality.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
