[0025] See also Figure 1-5 , the present invention provides the following technical solutions:

[0026] Example 1

[0027] A powdered fertilizer production and conveying device with an automatic sampling function, comprising:

[0028] A conveying cylinder 2, a feeding hopper 4 is arranged on one side of the upper end of the conveying cylinder 2, a discharging hopper 11 is arranged on the other side of the lower end, and a supporting seat 1 is arranged at the lower end of the conveying cylinder 2, and the supporting seat 1 is arranged in a groove shape to stably support the conveying cylinder;

[0029] A movable plate 17 is arranged below the discharge hopper 11. A through hole 16 is provided on the movable plate 17. A notch is horizontally provided inside the movable plate 17. A baffle 15 is provided inside the notch. The baffle 15 blocks the through hole 16. A second electric push rod 13 is provided on one side of the baffle 15. The outer sliding connection of the movable plate 17 is connected to a limit frame 6. The limit frame 6 is arranged in a groove shape. The movable plate 17 is located in the groove. A through hole is provided at the lower end of the limit frame 6. The through hole is connected to a second air pipe 14. A first electric push rod 12 is provided on one side of the movable plate 17. The first electric push rod 12 is fixed on the limit frame 6. A support frame 9 is provided on the upper end of the limit frame 6. The support frame 9 is fixed on the outer side of the conveying cylinder 2.

[0030] In this embodiment, in order to enable the sample in the through hole 16 to be transported to a longer distance, a first air pipe 10 is arranged at the upper end of the limiting frame 6 and at a position corresponding to the second air pipe 14. The first air pipe 10 is connected to the interior of the limiting frame 6, and the upper end of the first air pipe 10 is connected to the air outlet of the air pump 8, which is arranged at the upper end of the limiting frame 6.

[0031] In this embodiment, a spiral conveying shaft 5 is disposed inside the conveying cylinder 2, and one end of the spiral conveying shaft 5 extending out of the conveying cylinder 2 is connected to the output end of the first motor 3, and the first motor 3 is fixed on the support seat 1. In this embodiment, a sealing ring is disposed outside the through hole 16 and the adjacent side of the through hole to enhance the sealing during blowing, so that the conveying distance is longer, and one end of the second air pipe 14 is connected to the inlet end of the detection device for detection.

[0032] Specifically, the powdered fertilizer is transported through the conveying cylinder 2, and the fertilizer is put into the feeding hopper 4, and the first motor 3 rotates to drive the spiral conveying shaft 5 to rotate to transport the fertilizer. On the one hand, it blocks the outside world to prevent external factors from causing the powdered fertilizer to become wet and affecting the fertilizer quality. On the other hand, it facilitates the subsequent automatic sampling. The fertilizer falls from the discharge hopper 11, and the first electric push rod 12 drives the moving plate 17 to move toward the discharge hopper 11, to the through hole 16 to the bottom of the discharge hopper 11, so that the falling fertilizer falls into the through hole 16 for sampling, and then the first electric push rod 12 returns to its position, so that the through hole 16 is aligned with the upper and lower ends of the limit frame 6, and then the first electric push rod 12 is driven to move the moving plate 17 toward the discharge hopper 11, and the through hole 16 is aligned with the upper and lower ends of the limit frame 6. The second electric push rod 13 drives the baffle 15 to move, so that the baffle 15 moves to the side of the through hole 16, does not block the through hole 16, and the through hole 16 is unobstructed, so that the fertilizer enters the second air pipe 14 from the through port, and then the air pump 8 is turned on, and the air enters the through hole 16, the through port, and the second air pipe 14 from the first air pipe 10. The air pressure pushes the sample of the second air pipe 14 to quickly enter the detection device for detection. The detection is fast and simple, ensuring the timeliness of the detection, and then all the mechanisms return to their positions to wait for the next sampling. This process is automated, the sampling efficiency is high, no manual sampling is required, labor costs are saved, and there is no need to worry about missed detection, thereby ensuring the quality of the product.

[0033] Example 2

[0034] As an optional case, a powdered fertilizer production and conveying device with an automatic sampling function, the bottom of the groove of the support seat 1 is provided with an adjustment mechanism 7;

[0036] Specifically, the second motor 77 is started to rotate, thereby driving the gear 76 to rotate, thereby driving the rack 74 to extend downward, thereby moving the support plate 75, driving the sleeve 79 to extend, and the universal wheel 78 at the lower end of the sleeve 79 will contact the ground, thereby supporting the support base 1 so that the support base 1 leaves the ground, and then the device is moved by the universal wheel 78. After the device reaches the working location, the second motor 77 rotates in the opposite direction to the beginning, so that the rack 74, the support plate 75, and the sleeve 79 return to their original positions, thereby driving the universal wheel 78 to retract into the groove of the support base 1, so that the support base 1 contacts the ground, thereby increasing the contact area between the support base 1 and the ground, and increasing the placement stability, which ensures convenient and fast movement and transportation on the one hand, and stability during placement on the other hand, and automatic adjustment, which is simple and fast.
