[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0023] Example 1 Reference Figure 1-7 This is the first embodiment of the present invention, which provides a fertilizer granule sampling machine for fertilizer production, including a conveyor frame 1. The top of the conveyor frame 1 is provided with a conveying mechanism for conveying fertilizer granules. Above the conveying mechanism is a sweeping mechanism for sweeping fertilizer granules. Below the sweeping mechanism is a storage mechanism for storing fertilizer granules. Below the storage mechanism is a servo motor 13 for driving the sweeping mechanism and the storage mechanism. The front end of the conveyor frame 1 is provided with a control panel 4 for controlling the sweeping mechanism and the storage mechanism.

[0024] Specifically, by setting up a conveying mechanism, a sweeping mechanism, a storage mechanism, a servo motor 13, and a control panel 4, the problems encountered in the traditional fertilizer granule sampling process, such as poor data traceability, large sampling deviation, long manual sampling time, large human factors in sampling, and unsafe factors affecting the sampling process, are solved. The results achieve accurate data traceability, reduced sampling deviation, reduced manual sampling time, consistent operation, less human intervention, and high safety.

[0025] Furthermore, during use, the user continuously transports fertilizer granules through the drive conveyor mechanism, and the fertilizer granule sample is swept by the servo motor 13 driving the sweeping structure. The swept sample is then swept into the collection structure. The servo motor 13 can be controlled through the control panel 4, and the sweeping time can be set, or the fertilizer granules can be sampled intermittently.

[0026] Example 2 The second embodiment of this utility model provides a fertilizer granule sampling machine for fertilizer production. The conveying mechanism includes a transmission pulley 2, which is movably connected to both ends of a conveying frame 1. A conveyor belt 3 is sleeved on the outer side of the transmission pulley 2. A support plate 12 is provided at one end of the rear side of the conveying frame 1. A drive motor 5 is fixedly connected to the support plate 12. A transmission box 6 is provided at the upper end of the drive motor 5. The transmission box 6 is fixedly connected to the conveying frame 1. The output end of the drive motor 5 is connected to the input end of the transmission box 6. The output end of the transmission box 6 is connected to the transmission pulley 2.

[0027] Specifically, by setting up a conveying mechanism, when in use, the drive motor 5 drives the transmission pulley 2 to rotate through the transmission box 6. The transmission pulley 2 drives the conveyor belt 3 to move, and the material on the conveyor belt 3 is transported by the conveying mechanism to achieve the effect of transporting materials.

[0028] Furthermore, the user can turn on the drive motor 5, which in turn causes the transmission pulley 2 to rotate through the transmission box 6, thereby driving the conveyor belt 3, through which the fertilizer granules are conveyed.

[0029] Example 3 The third embodiment of this utility model provides a fertilizer granule sampling machine for fertilizer production. The sweeping mechanism includes a transmission rod 23, a swing arm 24 fixedly connected to the top of the transmission rod 23, and a plurality of telescopic rods 25 fixedly connected to the bottom of the swing arm 24. A brush plate 27 is fixedly connected to the extended end of the telescopic rod 25. A first spring 26 is respectively wrapped around the outside of the telescopic rod 25. One end of the first spring 26 is fixedly connected to the swing arm 24, and the other end of the first spring 26 is fixedly connected to the brush plate 27. A track plate 9 fixedly connected to the conveyor frame 1 is provided at the upper end of the conveyor belt 3. The bottom of the track plate 9 is higher than the top of the conveyor belt 3. A sliding groove 18 is opened on the inner side of the track plate 9. A slider 28 is fixedly connected to the side of the brush plate 27 near the track plate 9. The slider 28 is slidably connected to the sliding groove 18.

[0030] Specifically, by setting up a sweeping mechanism, the rotation of the drive rod 23 driven by the servo motor 13 drives the swing arm 24 to swing left and right. The design of the first spring 26, the slider 28 and the groove 18 allows the brush plate 27 to be lifted up when swinging towards the conveyor belt 3 and to fall down when sweeping, thereby achieving the effect of sweeping fertilizer particles on the conveyor belt 3. The design of the groove 18 allows the slider to drive the brush plate 27 to be lifted.

[0031] Furthermore, when the user uses the servo motor 13, the drive transmission rod 23 rotates, and the drive transmission rod 23 drives the swing arm 24 to sweep fertilizer particles into the storage mechanism. When the servo motor 13 drives the brush plate 27 to reset, the slider 28 moves along the guide rail trajectory, so that the brush plate 27 is lifted upwards while resetting, which can avoid repeated sweeping of fertilizer particles.

[0032] Example 4 The fourth embodiment of this utility model provides a fertilizer granule sampling machine for fertilizer production. The storage mechanism includes a fixed base 11, a servo motor 13 fixedly connected to the top of the fixed base 11, a ratchet mechanism at the output end of the servo motor 13, a turntable 10 on the outer side of the ratchet mechanism, a plurality of sampling boxes 8 movably connected to the upper end of the turntable 10, a support column 14 between the turntable 10 and the fixed base 11, the lower end of the support column 14 fixedly connected to the fixed base 11, the upper end of the support column 14 movably connected to the turntable 10, and a round lock 16 for locking the sampling boxes 8 on the outer side of the turntable 10. The ratchet mechanism includes a central drive wheel 22, around which several contraction grooves are formed. A second spring 21 is provided inside each contraction groove. One end of the second spring 21 is fixedly connected to the inner wall of the contraction groove, and the other end of the second spring 21 is fixedly connected to a ratchet block 20. An annular ratchet ring 19 is provided on the outer side of the central drive wheel 22. The ratchet block 20 and the annular ratchet ring 19 cooperate with each other. The bottom of the annular ratchet ring 19 is fixedly connected to the turntable 10. The output end of the servo motor 13 is fixedly connected to the bottom of the central drive wheel 22, and the upper end of the central drive wheel 22 is fixedly connected to the bottom of the transmission rod 23.

[0033] Specifically, by setting up a storage mechanism, when in use, the central transmission wheel 22 is driven by the servo motor 13. When the servo motor 13 drives the central transmission wheel 22 to rotate forward, the turntable 10 and the swing mechanism work together. When the servo motor 13 drives the central transmission wheel 22 to rotate in reverse, the ratchet block 20 compresses the second spring 21 and the turntable 10 does not move. The swing mechanism rotates in reverse to sweep fertilizer particles into the sampling box 8. The servo motor 13 rotates forward to remove the next sampling box 8. The position of the sampling box 8 is fixed by the design of the round lock 16.

[0034] Furthermore, when the user uses the device, the servo motor 13 drives the central transmission wheel 22, which in turn drives the sweeping mechanism. When the sweeping mechanism sweeps, the ratchet block 20 of the central transmission wheel 22 compresses the second spring 21, causing the ring and wheel to stop. When the servo motor 13 drives the sweeping mechanism back to the sweeping position, the central transmission wheel 22 rotates forward, and the turntable 10 and the swing mechanism move together. After sampling is completed, the sampling box 8 can be removed by releasing the locking tongue of the round lock 16. Example 5 The fifth embodiment of this utility model provides a fertilizer granule sampling machine for fertilizer production. The sampling box 8 is provided with a protective cover plate 17 fixedly connected to the conveyor frame 1. The upper end of the protective cover plate 17 is fixedly connected to the collection baffle 7. The outer side of the sampling box 8 is fixedly connected to the handle 15.

[0035] Specifically, by setting up a protective cover plate 17 and a collection baffle plate 7, the collection baffle plate 7 can prevent fertilizer particles from flying out during the collection and sweeping of fertilizer particles, and the design of the protective cover plate 17 can prevent the volatilization of fertilizer particles, while preventing impurities from being mixed in after collection.

[0036] Furthermore, when the user uses the device, the fertilizer particles swept by the sweeping mechanism can be prevented from flying out or being swept into other sampling boxes 8. The design of the protective cover 17 prevents the fertilizer from volatilizing or being mixed with other impurities.

[0037] Working principle: In use: The user issues a timed drive command to the servo motor 13 via the control panel 4, and activates the drive motor 5 to convey fertilizer. When the servo motor 13 rotates forward, it drives the central transmission wheel 22 to rotate. The ratchet block 20 of the central transmission wheel 22 drives the annular ratchet ring 19 to rotate, which enables the rotation and replacement of the material picking box. At the same time, the central transmission wheel 22 drives the transmission rod 23 to rotate. The rotating transmission rod 23 drives the swing arm 24 to swing. The swing arm 24 moves towards the conveyor belt 3. The slider 28 on the brush plate 27 moves along the slide rail, causing the brush plate 27 to lift upwards. When the servo motor 13 reverses, the ratchet block 20 of the central transmission wheel 22 compresses the second spring 21 due to the action of the annular ratchet ring 19, so the annular ratchet ring 19 does not move. The brush plate 27 on the sweeping mechanism swings to sweep the fertilizer particles into the sampling box. When the sampling is completed within the set time, the drive motor 5 is turned off, the user releases the round lock 16 of the sampling box 8, removes the sampling box 8, and sends the material into the inspection chamber for inspection.

[0038] In summary, through the coordination of the control panel 4, servo motor 13, drive motor 5, central transmission wheel 22, first spring 26, second spring 21, ratchet block 20, annular ratchet ring 19, brush plate 27, material collection box, transmission rod 23, swing arm 24, conveyor belt 3, slider 28, track plate 9, and slide 18, accurate data traceability and reduced sampling deviation are achieved, reducing manual sampling time, resulting in consistent operation, less human intervention, and high safety. This solves the problems encountered in traditional fertilizer granule sampling, such as poor data traceability, large sampling deviation, long manual sampling time, significant human factors, and unsafe factors affecting the sampling process.
