[0029] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0030] It should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0031] like Figures 1 to 8 As shown, a real-time mixing device for applying organic fertilizer and chemical fertilizer of the present invention comprises a storage box 1 and a screw conveyor and an electric-driven fertilizer discharger 11 both located below the storage box 1. The real-time mixing device of the present invention is generally installed on a fertilizer spreader, and the fertilizer spreader is installed behind a tractor, so that walking fertilization is achieved by traction of the tractor.

[0032] The screw conveyor is horizontally arranged below the storage box 1, and the length direction of the screw conveyor is parallel to the fertilizer running direction. Figure 1 As shown, the screw conveyor includes a circular feeding cylinder 7 and a spiral blade shaft 8 axially connected to the feeding cylinder 7 , and a spiral blade 9 is fixedly connected to the spiral blade shaft 8 , so that spiral conveying is achieved through the rotation of the spiral blade shaft 8 .

[0033] The inlet of the screw conveyor is arranged above the feeding end, and the inlet of the screw conveyor is the organic fertilizer discharge port 10, which is arranged above the discharge end.

[0034] The electric drive fertilizer dispenser 11 is an existing structure that achieves quantitative fertilizer discharge through motor rotation. The drive motor of the electric drive fertilizer dispenser 11 is a speed-regulating motor, which can adjust the fertilizer application speed. The upper end of the electric drive fertilizer dispenser 11 is connected to the storage box 1, and the lower end is provided with a fertilizer discharge port 12.

[0035] The organic fertilizer discharge port 10 of the screw conveyor and the chemical fertilizer discharge port 12 of the electric drive fertilizer dispenser 11 are arranged front and back along the moving direction of the real-time blending device, thereby achieving mixing of the organic fertilizer and the chemical fertilizer after application in the conveying direction.

[0036] A vertical partition 3 is installed in the storage box 1, which is not directly connected to the storage box 1, so that the position of the partition 3 is adjusted. The partition 3 divides the storage box 1 into an organic fertilizer box connected to the screw conveyor inlet and a chemical fertilizer box connected to the inlet of the electric-driven fertilizer discharger 11. The inlet of the electric-driven fertilizer discharger 11 and the inlet of the screw conveyor are respectively connected to one end away from the partition 3, so that the organic fertilizer and the chemical fertilizer flow in opposite directions and enter the electric-driven fertilizer discharger 11 and the screw conveyor, respectively.

[0037] The inner shaft of the storage box 1 is connected to a conveying main shaft 4 that passes through the organic fertilizer box and the chemical fertilizer box. One end of the conveying main shaft 4 is connected to a power source. The power source in this embodiment is the rear output shaft of the tractor. One end of the conveying main shaft 4 is connected to the rear output shaft of the tractor through a universal joint coupling, thereby realizing the rotation of the conveying main shaft 4.

[0038] The other end of the conveying main shaft 4 drives the spiral blade shaft 8 of the screw conveyor to rotate through a variable transmission ratio mechanism. The variable transmission ratio mechanism includes at least two sprocket transmission assemblies with different transmission ratios. In this embodiment, two sprocket transmission assemblies are provided.

[0039] The sprocket transmission assembly includes a passive sprocket 6 fixed to the spiral blade shaft 8 and a driving sprocket 5 sleeved on the conveying main shaft 4. The two passive sprockets 6 are of different sizes, and the two driving sprockets 5 are of different sizes to achieve different transmission ratios.

[0040] The conveying spindle 4 of the inner ring of the driving sprocket 5 is polygonal in shape, and a set screw 13 fastened to the polygon is installed on the driving sprocket 5. When in use, only the set screw 13 on one of the driving sprockets 5 needs to be tightened, and the remaining set screws 13 are removed or loosened. This drives the corresponding driven sprocket 6 to rotate through the driving sprocket 5, and the driven sprocket 6 drives the spiral blade shaft 8 to rotate. At the same time, all the driven sprockets 6 drive all the driving sprockets 5 to rotate, and the driving sprockets 5 without the set screws 13 tightened will idle on the conveying spindle 4.

[0041] A plurality of stirring and conveying paddles 2 are detachably fixedly connected to the conveying main shaft 4. The stirring and conveying paddles 2 in the organic fertilizer box stir and convey the organic fertilizer toward the inlet of the screw conveyor. The stirring and conveying paddles 2 in the chemical fertilizer box stir and convey the chemical fertilizer toward the inlet of the electric-driven fertilizer discharger 11. Since the inlet of the electric-driven fertilizer discharger 11 and the inlet of the screw conveyor are respectively connected to one end away from the partition 3, the organic fertilizer conveying direction of the stirring and conveying paddles 2 in the organic fertilizer box is opposite to the fertilizer conveying direction of the stirring and conveying paddles 2 in the chemical fertilizer box.

[0042] The bottom of the storage box 1 is arc-shaped and adapted to the rotation outer diameter of the stirring and conveying paddle 2. Thus, the stirring and conveying paddle 2 can fully stir the chemical fertilizer and the organic fertilizer, making it convenient for the chemical fertilizer and the organic fertilizer to flow to the next step.

[0043] The partition 3 has a through hole for the conveying main shaft 4 to pass through, and the partition 3 is limited between two adjacent stirring and conveying paddles 2. Since the stirring and conveying paddles 2 are detachably fixed to the conveying main shaft 4, the position of the partition can be adjusted by removing the stirring and conveying paddle 2 on one side of the partition 3, moving the partition 3 by the distance of the stirring and conveying paddle 2, and then installing the removed stirring and conveying paddle 2 on the other side of the partition 3, thereby adjusting the size ratio between the machine fertilizer box and the chemical fertilizer box.

[0044] like Figure 2-4 As shown, the conveying main shaft 4 in the storage box 1 is a square shaft, and the stirring conveying paddle 2 includes two mounting half sleeves 21 and two flat paddle blades 22 respectively passing through the mounting half sleeves 21. The paddle blades 22 are steel plates and form a certain angle with the axis of the conveying main shaft 4, so as to realize the conveying effect of the material during the stirring process. The inclination directions of the paddle blades 22 on both sides of the partition 3 are opposite, so the conveying directions are opposite, as shown in FIG. Figure 2 Shown are the stirring and conveying paddles 2 in two conveying directions.

[0045] The mounting half sleeve 21 is U-shaped. The two mounting half sleeves 21 are connected by bolts and form a square hole that matches the square shaft, so that the mounting half sleeve 21 is fixed on the square shaft. Each mounting half sleeve 21 has 4 bolt through holes.

[0046] One end of the paddle blade 22 is fixedly connected to a paddle blade base plate 23 located between the mounting half sleeve 21 and the square shaft. The paddle blade base plate 23 is squeezed tightly by the mounting half sleeve 21 and the square shaft, thereby preventing the paddle blade 22 from falling off and achieving a fixing effect.

[0047] The mounting half 21 has two paddle notches 24 for the paddle blades 22 to pass through. The two paddle notches 24 are arranged crosswise. In this embodiment, the two paddle notches 24 are arranged perpendicularly. When installing the mixing and conveying paddle 2 from one side of the partition 3 to the other, the paddle blade 22 needs to be inserted into the other paddle notch 24, thereby changing the tilt direction and changing the material conveying direction.

[0048] Since the conveying main shaft 4 in the storage box 1 is a square shaft and the through hole on the partition 3 is a round hole, the present application will cover the through hole with the two mounting half sleeves 21 adjacent to the partition 3 to prevent the gap between the round hole and the square shaft from allowing material to pass through.

[0049] A method for using a real-time mixing device for applying organic fertilizer and chemical fertilizer comprises the following steps: a. driving a conveying main shaft 4 to rotate by a power source, thereby stirring and conveying the organic fertilizer toward the inlet of a screw conveyor by a stirring and conveying paddle 2 in an organic fertilizer tank, stirring and conveying the chemical fertilizer toward the inlet of an electric-driven fertilizer discharger 11 by a stirring and conveying paddle 2 in a chemical fertilizer tank, and conveying the organic fertilizer outwardly to a fertilizing area by the screw conveyor, and conveying the chemical fertilizer outwardly to the fertilizing area by the electric-driven fertilizer discharger 11;

[0050] b. The conveying spindle 4 drives the spiral blade shaft 8 of the screw conveyor to rotate through a variable transmission ratio mechanism. The variable transmission ratio mechanism includes at least two sprocket transmission assemblies. By fastening the set screws 13 on the driving sprocket 5 in different sprocket transmission assemblies to the conveying spindle 4, the transmission ratio is adjusted to adjust the conveying speed of the screw conveyor and the fertilization speed of the organic fertilizer;

[0051] c. By removing the stirring and conveying paddle 2 adjacent to the partition 3, the position of the partition can be adjusted, thereby adjusting the size ratio between the organic fertilizer tank and the chemical fertilizer tank;

[0052] d. The stirring and conveying direction of the stirring and conveying paddle 2 is adjusted by passing the paddle blades 22 of the removed stirring and conveying paddle 2 through different paddle blade notches 24 .

[0053] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
