[0004] In the aforementioned utility model patent, after the ingredients are weighed, they fall directly into the box through the feed pipe, causing the same ingredients to concentrate in a local area of ​​the box. This increases the time required for the mixing mechanism to evenly mix the various ingredients, thus affecting production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fertilizer production ingredient mixing device, which solves the problem in existing technologies where the same ingredient is concentrated in a local area of ​​the box, resulting in increased time required for uniform mixing of multiple ingredients.

[0006] According to an embodiment of this utility model, a fertilizer production ingredient mixing device includes a frame, a tank and a cover that cooperates with the tank on the frame, a stirring assembly on the cover, the stirring assembly including a rotatable stirring shaft and a drive motor that is pulsatorically connected to the stirring shaft, the stirring shaft extending into the tank, the cover also having a feeding hopper, a feeding pipe and a feeding port connected in sequence on the cover, the feeding port communicating with the tank, the feeding pipe having a movable plate with a through-hole on the movable plate, the movable plate also having an annular portion, the stirring shaft having an eccentric wheel located within the annular portion, the cover also having a spring with opposite ends in the extension direction of the spring abutting against the annular portion and the cover respectively, driving the annular portion to abut against the eccentric wheel.

[0007] Furthermore, a plurality of first stirring blades are provided at intervals along the circumference of the stirring shaft, and the first stirring blades are respectively spiral-shaped.

[0008] Furthermore, a plurality of second stirring blades are provided at circumferential intervals along the stirring shaft, and the second stirring blades are staggered with the first stirring blades.

[0009] Furthermore, a scraper is provided at the end of the second stirring blade away from the stirring shaft, and the scraper is positioned close to the inner wall of the tank.

[0010] Furthermore, the feeding pipe is provided with a groove, and the movable plate is in contact with the inner wall of the groove.

[0011] Furthermore, a guide rod is provided between the movable plate and the annular portion, the spring is sleeved on the guide rod, and a guide seat is provided on the cover, with a guide hole that cooperates with the guide rod.

[0012] Furthermore, the outer peripheral wall of the guide rod is provided with a limiting protrusion, and the guide seat is provided with a limiting groove that cooperates with the limiting protrusion and the limiting groove communicates with the guide hole.

[0015] Compared with the prior art, this utility model has the following beneficial effects: By using a drive motor mounted on the cover to drive the stirring shaft to rotate and stir the ingredients in the tank, and with the stirring shaft rotating synchronously, the eccentric wheel mounted on the stirring shaft rotates synchronously. Because the annular part remains in contact with the eccentric wheel under the action of a spring, the rotation of the eccentric wheel pushes the annular part to reciprocate, causing the movable plate to reciprocate on the feeding pipe. During the movement of the movable plate, the material outlet on the movable plate connects with or is misaligned with the feeding port. When the material outlet connects with the feeding port, the ingredients in the feeding hopper can pass through the feeding pipe and the feeding port. The feed hopper enters the tank through the inlet. When the feed inlet and the feed outlet are misaligned, the movable plate separates the feed hopper from the feed outlet, preventing the ingredients in the feed hopper from entering the tank. The ingredients in the feed hopper are intermittently added into the tank by the reciprocating movement of the movable plate on the feed pipe. At the same time, the ingredients in the tank are mixed by the stirring component. This solves the technical problem that the concentration of the same ingredients in a local area of ​​the tank increases the time required for uniform mixing of multiple ingredients. It has the technical effect of avoiding the accumulation of the same ingredients and shortening the time required for uniform mixing of ingredients, which is conducive to improving fertilizer production efficiency.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes a mixing device for fertilizer production, which is used to stir and mix multiple ingredients evenly during the fertilizer production process.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The fertilizer production mixing device includes a frame 1, on which a tank 2 and a cover 3 are mounted. The tank 2 is used to contain the ingredients to be mixed, and the cover 3 closes the opening of the tank 2. A stirring assembly 4 is mounted on the cover 3. The stirring assembly 4 includes a rotatable stirring shaft 41 and a drive motor 42 connected to the stirring shaft 41. The stirring shaft 41 extends into the tank 2, and the drive motor 42 drives the stirring shaft 41 to rotate, thus stirring the ingredients in the tank 2 to ensure uniform mixing. The cover 3 also has a feeding hopper 5, a feeding pipe 6, and a feeding port 31 connected in sequence. The feeding port 31 is connected to the tank 2. After the ingredients are added to the feeding hopper 5, they pass through the feeding pipe 6 and the feeding port 31 into the tank 2. The pipe 6 is provided with a movable plate 61 and a through-hole 62. The movable plate 61 is also provided with an annular part 63. The stirring shaft 41 is provided with an eccentric wheel 43 and the eccentric wheel 43 is located inside the annular part 63. The cover 3 is also provided with a spring 32 and the opposite ends of the spring 32 in the extension direction respectively abut against the annular part 63 and the cover 3, and drive the annular part 63 to abut against the eccentric wheel 43. When the drive motor 42 drives the stirring shaft 41 to rotate, the eccentric wheel 43 pushes the annular part 63 to move and drives the movable plate 61 to move back and forth on the feeding pipe 6. During the movement of the movable plate 61, the through-hole 62 is connected to or misaligned with the feeding port 31, so that the feed in the feeding hopper 5 intermittently passes through the feeding pipe 6 and enters the tank 2.

[0021] Specifically, the working process of the fertilizer production mixing device provided in this embodiment is as follows: after adding one ingredient to the tank 2, the cover 3 is installed on the tank 2 and the drive motor 42 is started. The drive motor 42 drives the stirring shaft 41 to rotate to stir the ingredients in the tank 2. Then, the remaining ingredients are added to the feeding hopper 5 in proportion so that the ingredients pass through the feeding port 31 along the feeding pipe 6 and enter the tank 2. When the stirring shaft 41 rotates, the eccentric wheel 43 set on the stirring shaft 41 rotates synchronously. Since the annular part 63 is kept in contact with the eccentric wheel 43 under the action of the spring 32, the eccentric wheel 43 rotates... During the movement, the annular part 63 is pushed to reciprocate, causing the movable plate 61 to reciprocate on the feeding pipe 6. During the movement of the movable plate 61, the material outlet 62 on the movable plate 61 is connected to or misaligned with the feeding port 31. When the material outlet 62 is connected to the feeding port 31, the ingredients in the feeding hopper 5 can pass through the feeding pipe 6 and the feeding port 31 into the tank 2. When the material outlet 62 is misaligned with the feeding port 31, the movable plate 61 separates the feeding hopper 5 from the feeding port 31, preventing the ingredients in the feeding hopper 5 from entering the tank 2. This allows the ingredients in the feeding hopper 5 to be intermittently added to the tank 2. The fertilizer production ingredient mixing device provided in this embodiment can intermittently add ingredients during the mixing process, avoiding the accumulation of the same ingredients in a local area of ​​the tank 2, thereby shortening the time required for uniform mixing and improving fertilizer production efficiency.

[0022] like Figure 3 As shown, a plurality of first stirring blades 44 are spaced apart along the circumference of the stirring shaft 41, and the first stirring blades 44 are spiral in shape. When the stirring shaft 41 rotates under the drive motor 42, the first stirring blades 44 rotate synchronously to agitate the ingredients in the tank 2, thereby making the ingredients in the tank 2 uniformly mixed.

[0023] like Figure 3 As shown, a plurality of second stirring blades 45 are arranged at intervals along the circumference of the stirring shaft 41, and the second stirring blades 45 are staggered with the first stirring blades 44. By using the second stirring blades 45, which are staggered from the first stirring blades 44, on the stirring shaft 41 to stir the ingredients simultaneously, it is beneficial to improve the stirring effect of the stirring assembly 4 and further shorten the time required for the ingredients to be mixed evenly.

[0024] In this embodiment, a scraper 46 is provided at the end of the second stirring blade 45 away from the stirring shaft 41, and the scraper 46 is disposed close to the inner wall of the tank 2. The scraper 46 disposed on the second stirring blade 45 is used to scrape off the ingredients adhering to the inner wall of the tank 2, so that the ingredients on the inner wall of the tank 2 are separated from the tank 2, preventing some ingredients from sticking to the inner wall of the tank 2 and affecting the uniformity of the mixing, and reducing ingredient loss.

[0025] Please refer to Figure 3 and Figure 4 The feeding pipe 6 is provided with a sliding groove 64, and the movable plate 61 is fitted against the inner wall of the sliding groove 64. The movable plate 61 is installed on the feeding pipe 6 through its cooperation with the sliding groove 64, and the movable plate 61 moves back and forth in the sliding groove 64 under the drive of the eccentric wheel 43, which prevents the movable plate 61 from deviating from the preset direction when moving, and helps to improve the stability of the fertilizer production batching and mixing device during operation.

[0026] like Figure 2 and Figure 4 As shown, a guide rod 65 is provided between the movable plate 61 and the annular portion 63. The spring 32 is sleeved on the guide rod 65. The cover 3 is provided with a guide seat 33, and the guide seat 33 has a guide hole that mates with the guide rod 65. The movable plate 61 and the annular portion 63 are connected by the guide rod 65, and the guide seat 33 is provided on the cover 3 with the guide hole that mates with the guide rod 65, ensuring a reliable fit between the movable plate 61 and the cover 3.

[0027] In detail, the guide rod 65 has a limiting protrusion 66 on its outer peripheral wall, and the guide seat 33 has a limiting groove that mates with the limiting protrusion 66 and communicates with the guide hole. When the guide rod 65 is inserted into the guide hole, the limiting protrusion 66 is inserted into the limiting groove to prevent the guide rod 65 from rotating unexpectedly during the reciprocating movement of the movable plate 61, thereby keeping the annular part 63 in contact with the eccentric wheel 43 and ensuring the overall structure of the fertilizer production mixing device remains stable.

[0028] like Figure 4As shown, the eccentric wheel 43 includes a connecting cylinder 47, which is sleeved on the stirring shaft 41. The cover 3 is provided with a limiting part 34 that cooperates with the connecting cylinder 47. The eccentric wheel 43 is installed on the stirring shaft 41 through the cooperation of the connecting cylinder 47 and the stirring shaft 41. The limiting part 34 on the cover 3 cooperates with the eccentric wheel 43 to keep the relative position of the eccentric wheel 43 and the stirring shaft 41 stable, preventing the eccentric wheel 43 from sliding along the axial direction of the stirring shaft 41 and causing the eccentric wheel 43 to disengage from the annular part 63.

[0029] Please combine Figure 1 and Figure 4 The tank body 2 is provided with a rotatable locking screw 21 and a corresponding locking knob 22. The cover body 3 is provided with a locking plate 48. The locking plate 48 is provided with a locking groove 49 that accommodates part of the locking screw 21. The locking knob 22 abuts against the side of the locking plate 48 away from the tank body 2. When the cover 3 is installed on the tank 2, it is pressed onto the tank 2 by the contact between the locking knob 22 and the locking plate 48, so that the opening of the tank 2 is kept closed to prevent the ingredients from leaking from the opening of the tank 2 during the mixing process. When it is necessary to remove the cover 3, turn the locking knob 22 to move the locking knob 22 away from the locking plate 48, and then turn the locking screw 21 to disengage the locking screw 21 from the locking groove 49 to remove the cover 3 from the tank 2, so as to facilitate the cleaning of the inside of the tank 2 and the stirring assembly 4.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
