DETAILED DESCRIPTION
[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a multi-stage stirring and blending device includes a blending chamber 20, which is in a hollow cylindrical shape. A rotating motor 21 is fixedly connected to the top of the blending chamber 20, and a feeding pipe 22 is also fixedly connected to the top of the blending chamber 20. The rotating motor 21 is electrically connected to a power source. The feeding pipe 22 is open at the top and hollow inside the cavity. The bottom of the feeding pipe 22 can be connected to the cavity of the blending chamber 20. This is an existing technology and will not be described in detail here.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, a stirring structure is provided in the cavity of the mixing chamber 20, and the stirring structure includes a rotating shaft 30, a first stirring plate 38 and a second stirring plate 34. The rotating shaft 30 is rotatably connected in the cavity of the mixing chamber 20, the first stirring plate 38 is fixedly connected in the cavity of the mixing chamber 20, and the second stirring plate 34 is fixedly connected to the wall of the rotating shaft 30. The stirring structure can stir the fertilizer, and the rotating motor 21 can drive the rotating shaft 30 to rotate. The rotating shaft 30 is cylindrical, and the top of the rotating shaft 30 can pass through the top of the mixing chamber 20 and be connected to the bottom of the rotating motor 21. The first stirring plate 38 is in the shape of an annular plate, and the top of the first stirring plate 38 is in the shape of a slope that gradually decreases toward a circle. The rotating shaft 30 can pass through the cavity of the first stirring plate 38, and the second stirring plate 34 is in the shape of a circular plate, and the top of the second stirring plate 34 is in the shape of a slope that gradually decreases toward the outer wall. The second stirring plate 34 is located at the vertical bottom of the first stirring plate 38.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the stirring structure also includes a stirring rod 31, a belt rod 32, a beating rod 35 and a bottom rod 37. The stirring rod 31 is fixedly connected to the outer wall of the rotating shaft 30, the belt rod 32 is fixedly connected to the bottom of the stirring rod 31, the beating rod 35 is fixedly connected to the top of the second stirring plate 34, the bottom rod 37 is symmetrically fixedly connected to the bottom of the rotating shaft 30, the bottom of the belt rod 32 can contact the top of the first stirring plate 38, the stirring rod 31 and the belt rod 32 are symmetrically arranged on the outer wall of the rotating shaft 30, the stirring rod 31 is fixedly connected to the rotating shaft 30 between the first stirring plate 38 and the top of the mixing chamber 20, and the cross section of the beating rod 35 is rectangular. A plurality of rods 35 are fixedly connected to the top of the second stirring plate 34. The plurality of rods 35 are distributed in a circular array on the top of the second stirring plate 34. The bottom of the bottom rod 37 can contact the bottom of the mixing chamber 20. A discharge pipe 40 is fixedly connected to the bottom of the mixing chamber 20. A drive motor 41 is fixedly connected to the rear wall of the discharge pipe 40. The discharge pipe 40 is in the shape of a hollow circular tube. An auger 42 is rotatably connected to the cavity of the discharge pipe 40. The top of the discharge pipe 40 can be connected to the bottom of the mixing chamber 20. The rear wall of the auger 42 can pass through the rear wall of the discharge pipe 40 and be connected to the drive motor 41.
[0027] During specific use, the power is turned on. At this time, the rotating motor 21 can drive the rotating shaft 30 to rotate in the mixing chamber 20. The rotating shaft 30 can drive the stirring rod 31, the belt rod 32, the second stirring plate 34 and the bottom rod 37 to rotate simultaneously during rotation. The second stirring plate 34 can drive the beating rod 35 to rotate. At this time, the fertilizer is poured into the top opening of the feed pipe 22. When the fertilizer enters the cavity of the feed pipe 22, it will directly enter the cavity of the mixing chamber 20. When the fertilizer enters the cavity of the mixing chamber 20, it will first fall on the top of the first stirring plate 38. When the fertilizer falls on the top of the first stirring plate 38, it will contact the high-speed rotating belt rod 32 and the stirring rod 31. When the fertilizer falls on the top of the first stirring plate 38, it will fall from the first stirring plate 38. The fertilizer will fall from the gap between the cavity and the rotating shaft 30 to the top of the second stirring plate 34 rotating at high speed. When the fertilizer falls to the top of the second stirring plate 34, it will also contact the beating rod 35. Then the fertilizer will finally fall from the gap between the second stirring plate 34 and the cavity of the mixing chamber 20 to the bottom of the cavity of the mixing chamber 20. When the fertilizer falls to the bottom of the cavity of the mixing chamber 20, it will also contact the high-speed rotating bottom rod 37 to complete multiple stirring. The driving motor 41 is electrically connected to the corresponding power supply. The driving motor 41 can drive the auger 42 to rotate in the cavity of the discharge pipe 40. When the fertilizer falls to the bottom of the cavity of the mixing chamber 20, it will directly move into the cavity of the discharge pipe 40 and then be discharged from the cavity of the discharge pipe 40 along with the rotating auger 42.
[0028] In summary, by setting up a stirring structure, the fertilizer can be stirred and discharged endlessly, because the stirring structure increases the residence time of the fertilizer in the mixing chamber 20 by setting the first stirring plate 38 and the second stirring plate 34 and cooperates with the stirring rod 31, the beating rod 35 and the bottom rod 37 to stir the fertilizer so that it can be stirred and discharged endlessly. This process only requires adding the fertilizer from the opening of the feed pipe 22. Therefore, compared with the prior art, this solution is more convenient for stirring and discharging the fertilizer for a long time.
[0029] like Figure 3 As shown, the stirring structure also includes a first scraper 33 and a second scraper 36. The first scraper 33 is fixedly connected to the wall surface of the belt rod 32, and the second scraper 36 is fixedly connected to the top of the bottom rod 37. The walls of the first scraper 33 and the second scraper 36 can contact the inside of the mixing chamber 20. The second scraper 36 is also fixedly connected to the outer wall surface of the second stirring plate 34. The second scraper 36 and the stirring rod 31 are symmetrically arranged in the mixing chamber 20. The total height of the second scraper 36 and the stirring rod 31 is consistent with the height of the inner wall surface of the mixing chamber 20.
[0030] When in use, when the belt rod 32, the stirring rod 31, the second stirring plate 34 and the bottom rod 37 rotate, the first scraper rod 33 and the second scraper rod 36 will be driven to rotate in the mixing chamber 20 at the same time. When the first scraper rod 33 and the second scraper rod 36 rotate, they will also contact the inner wall surface of the mixing chamber 20 to scrape away the fertilizer attached to the inner wall surface of the mixing chamber 20.
[0031] In summary, by providing the first scraper 33 and the second scraper 36, the inner wall surface of the mixing chamber 20 can be cleaned during rotation. Because part of the fertilizer will adhere to the wall surface of the mixing chamber 20 during mixing, the first scraper 33 and the second scraper 36 can just scrape off this part of the fertilizer to prevent the fertilizer from accumulating on the wall surface of the mixing chamber 20 and affecting the working efficiency of the device.
[0032] Working principle: Turn on the power supply, and the rotating motor 21 can drive the rotating shaft 30 to rotate in the mixing chamber 20. The rotating shaft 30 can drive the stirring rod 31, the belt rod 32, the second stirring plate 34 and the bottom rod 37 to rotate simultaneously during rotation. The second stirring plate 34 can drive the beating rod 35 to rotate. At this time, pour the fertilizer from the top opening of the feed pipe 22. When the fertilizer enters the cavity of the feed pipe 22, it will directly enter the cavity of the mixing chamber 20. When the fertilizer enters the cavity of the mixing chamber 20, it will first fall on the top of the first stirring plate 38. When the fertilizer falls on the top of the first stirring plate 38, it will contact the high-speed rotating belt rod 32 and the stirring rod 31. When the fertilizer falls on the top of the first stirring plate 38, it will fall from the cavity of the first stirring plate 38. The fertilizer will fall from the gap between the second stirring plate 34 and the rotating shaft 30 to the top of the second stirring plate 34 which rotates at a high speed. When the fertilizer falls to the top of the second stirring plate 34, it will also contact the beating rod 35. Then the fertilizer will finally fall from the gap between the second stirring plate 34 and the mixing chamber 20 to the bottom of the mixing chamber 20. When the fertilizer falls to the bottom of the mixing chamber 20, it will also contact the high-speed rotating bottom rod 37 to complete multiple stirring. The driving motor 41 is electrically connected to the corresponding power supply. The driving motor 41 can drive the auger 42 to rotate in the discharge pipe 40. When the fertilizer falls to the bottom of the mixing chamber 20, it will directly move into the discharge pipe 40 and then be discharged from the discharge pipe 40 as the auger 42 rotates.
