The slides contain a removable feed port. The mixing box 1 is equipped with a pull-out sealing plate; the mixing box 1 has two vertically arranged partitions 1-4, which divide the interior of the mixing box 1 into a first split box 1-1, a second split box 1-2, and a third split box 1-3. The lower ends of the first split box 1-1, the second split box 1-2, and the third split box 1-3 are connected and communicate with the opening; the lower part of the mixing box 1 is provided with a narrowing section, which is located near the lower end of the third split box 1-3; the mixing box 3 includes a mixing box plate 3-1, which forms a vertically continuous cylindrical structure, and the inner side of the lower end of the mixing box plate 3-1...

The mixing tank plate 5-1 has a motor 4 installed on its exterior. The output shaft of the motor 4 passes through the mixing tank plate 5-1 and is connected to the mixing assembly inside it, driving the mixing assembly to rotate. The mixing assembly includes a mixing shaft connected to the output shaft of the motor 4 via a spline. Several mixing rods 5-2 are evenly arranged on the mixing shaft. The ends of the mixing rods 5-2 are fixedly connected to a mixing plate 5-3, which has an arc-shaped plate structure. A feeding gate is provided at the lower end of the mixing tank plate 5-1 for controlling the opening or closing of the feeding port 6. A belt conveyor 7 for transporting the blended fertilizer is provided below the mixing tank 5.

[0025] The first embodiment of this utility model is as follows:

[0026] A compound fertilizer feeding device includes a support 2, on which a batching box 1, a mixing box 3, and a stirring box 5 are arranged from top to bottom. A belt conveyor 7 for transporting the compound fertilizer is located below the stirring box 5. In use, two or three fertilizers are simultaneously or sequentially fed into the batching box 1. After initial mixing, the fertilizers enter the mixing box 3. Fertilizer particles pass randomly through numerous holes on a sieve plate 3-2, which disperses the fertilizer and increases the space between the particles, allowing other types of fertilizer particles to enter these spaces, thus achieving mixing of different fertilizer types. This process is completed naturally during the batching process. The mixed waste then enters the stirring box 5. Based on the previous mixing, only simple stirring is needed to achieve thorough mixing. The entire process can be carried out simultaneously, with material being fed from the batching box 1 while mixing and stirring are performed, and the fully mixed fertilizer being discharged from the batching port, greatly improving work efficiency.

[0027] The mixing box 1 is internally divided into several separate boxes for storing different types of fertilizers. Typically, the mixing box 1 has two vertically arranged partitions 1-4 of different lengths, which divide the interior of the mixing box 1 into a first separate box 1-1, a second separate box 1-2, and a third separate box 1-3. The lower ends of the first separate box 1-1, the second separate box 1-2, and the third separate box 1-3 are connected and communicate with an opening. The lower part of the mixing box 1 has a narrowing section, which is located near the lower end of the third separate box 1-3. The shorter partition 1-4 is positioned near the narrowing section, ensuring that the straight-line distance between the shorter partition 1-4 and the inclined surface of the narrowing section is equal to the distance between the longer partition 1-4 and the sieve plate 3-2. When three different types of fertilizers are respectively fed into the first split box 1-1, the second split box 1-2, and the third split box 1-3, the three fertilizers can be collected at the outlet. At the same time, each type of waste occupies roughly the same space, and the distance between the three fertilizers will not be too far when using the narrowing section, thus improving the mixing efficiency of the three wastes.

[0028] The lower part of the mixing box 1 is provided with an opening, and slides are provided on both sides of the opening. The sealing plate of the mixing box 1 is provided in the slide in a pull-out manner. There are two slides, located on both sides of the lower end of the mixing box 1 respectively. The cross-sectional shape of the slide is U-shaped, and the slots are laterally opposite. The sealing plate of the mixing box 1 can be pulled out by inserting it into the slot. The opening or closing of the mixing box 1 can be changed by the sealing plate of the mixing box 1.

[0029] An end plate is provided at the end of the sealing plate of the mixing box 1 to position the sealing plate of the mixing box 1. The end plate closes the mixing box 1 when it abuts against it. A handle is provided on the end plate for easy operation.

[0030] Directly below the opening is the mixing tank 3.

[0031] The mixing box 3 includes a mixing box plate 3-1, which forms a rectangular cylindrical structure that runs vertically through the box. Waste material that has been preliminarily mixed in the batching box 1 enters the mixing box 3 from the top. A support part 3-4 is provided on the inner side of the lower end of the mixing box plate 3-1. Eight vertically extending cavities 3-7 are evenly arranged on the support part 3-4. The support part 3-4 also has a vertically extending slot that communicates with the cavity 3-7. A spring 3-5 is provided in the lower part of the cavity 3-7. A connecting rod 3-6 is provided above the spring 3-5. One end of the connecting rod 3-6 extends from the slot to the outside of the cavity 3-7 and connects to the screen plate 3-2. A vibrator 3-3 is fixedly installed at the center of gravity below the screen plate 3-2. Vibration is generated by the vibrator 3-3, causing the screen plate 3-2 to vibrate vertically, which accelerates the speed at which fertilizer particles pass through the holes of the screen plate 3-2, improves the mixing efficiency, and also prevents accumulation. During vibration, springs 3-5 can play an auxiliary role and reduce noise.

[0032] The surface of the sieve plate 3-2 is provided with a large number of evenly distributed holes. The diameter of the holes is larger than the diameter of the fertilizer particles, which ensures that the fertilizer particles can pass through quickly without accumulating, and can also be fully dispersed to ensure the mixing effect.

[0033] Directly below the sieve plate 3-2 is the mixing tank, where fertilizer particles passing through the sieve plate 3-2 are mixed.

[0034] The mixing tank 5 includes a mixing tank plate 5-1. A motor 4 is installed on the outside of the mixing tank plate 5-1. The output shaft of the motor 4 passes through the mixing tank plate 5-1 and is connected to the mixing assembly inside it, driving the mixing assembly to rotate. The mixing assembly includes a mixing shaft connected to the output shaft of the motor 4 via a spline. Several mixing rods 5-2 are evenly arranged on the mixing shaft. The ends of the mixing rods 5-2 are fixedly connected to a mixing plate 5-3. The mixing plate 5-3 has an arc-shaped plate structure. In this embodiment, the mixing tank 5 includes two identical parts, with a semi-circular lower part and a rectangular upper part. It is equipped with two mixing shafts and two motors 4, which drive the two sets of mixing rods 5-2 and mixing plates 5-3 to rotate. The mixing directions of the two motors 4 are opposite, both causing the fertilizer particles to gather from the edge to the center, ensuring that the fertilizer particles can be fully exchanged and mixed.

[0035] The stirring shaft can be rotated 90 degrees to adjust the relative angle between the mixing tank 5 and the ingredient tank 1, thereby changing the mixing effect. For example, when the stirring shaft is perpendicular to the partition 1-4, the mixing efficiency can be further improved.

[0036] The lower end of the mixing tank plate 5-1 is provided with a feeding door for controlling the opening or closing of the feeding port 6. The structure of the feeding door is the same as the sealing plate structure of the batching box 1 at the lower opening of the batching box 1, which can be used as a reference and will not be described in detail here.

[0037] The fully mixed fertilizer discharged from the feeding gate will fall onto belt conveyor 7, which will then be transported externally for bagging or transfer.

[0038] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
