Description

Technical Field

[0001] The utility model belongs to the field of fertilizer boxes for seed drills, in particular to a fertilizer conveying device. Background Art

[0002] Traditional fertilization methods typically rely on motors or mechanical transmissions to drive impeller-type fertilizer delivery devices. Due to limitations in the fertilizer bin structure and the location of the fertilizer outlet, fertilizer can be unevenly distributed during application, requiring manual intervention to remove any remaining fertilizer. To address this issue, existing auger-type fertilizer-pushing devices have been developed. However, these devices still struggle to remove the fertilizer from the bottom of the bin. Therefore, finding a more efficient way to clean the bottom of the bin is a pressing technical challenge for those skilled in the art. Summary of the Invention

[0003] In order to solve the above problems, the technical solution used in the utility model is as follows: a fertilizer box capable of reducing the accumulation of fertilizer at the bottom of the box, characterized in that it includes a box body (1), an auger (2), a fertilizer cleaning brush (3), a fertilizer discharge port (4), an auger support frame (5), a DC motor (6), and a motor driver (7), wherein the auger (2) is installed inside the box body (1), one end of the auger (2) shaft is supported on the side wall of the box body (1), and the other end is connected to the shaft of the DC motor (6) and fixed on the opposite side of the box body (1); the middle part of the auger (2) is supported on the auger support frame (5), the auger support frame (5) is horizontally placed above the box body (1) and fixed on the front and rear side walls of the box body (1), four fertilizer discharge ports (4) are provided at the bottom of the box body (1), the DC motor (6) is connected to the motor driver (7) and is installed on the same side of the box body (1); one end of the motor driver (7) is connected to the DC motor (6) and the other end is connected to the external power supply device.

[0004] The auger (2) is provided with four blades (10), which are symmetrically arranged on the auger (2) shaft. The rotation direction of the two blades (10) close to the motor side is opposite to the rotation direction of the two blades (10) away from the motor side. The fertilizer discharge port (4) is provided at the disconnection point of the four blades so that the fertilizer pushed by the auger (2) blades (10) can be discharged in time; the fertilizer cleaning brush (3) is connected to the brush base (8), and the brush base (8) is fixed on the auger (2) blades (10). The brush base (8) and the auger blades are provided with corresponding brush fixing holes (9), and the fertilizer cleaning brush is fixed to the blades by bolt connection.

[0005] Compared with the existing technology, the beneficial effects of the utility model are: the rotation of the auger can open up the compacted fertilizer, ensure smooth fertilizer discharge, the fertilizer box improves the utilization rate of the fertilizer, the blade brush can clean the fertilizer accumulation at the corners of the box to a greater extent, solve the problem of fertilizer accumulation at the bottom, and simplify the cleaning and maintenance of the fertilizer box.

[0010] The following is a further detailed description of a fertilizer box of the present invention that can reduce fertilizer accumulation at the bottom of the box with reference to the accompanying drawings.

[0011] like Figures 1 to 3 As shown, a fertilizer box capable of reducing fertilizer accumulation at the bottom of the box is characterized in that it includes a box body (1), an auger (2), a fertilizer cleaning brush (3), a fertilizer discharge port (4), an auger support frame (5), a DC motor (6), and a motor driver (7), wherein the auger (2) is installed inside the box body (1), one end of the auger (2) shaft is supported on the side wall of the box body (1), and the other end is connected to the DC motor (6) shaft and fixed to the opposite side of the box body (1); the middle part of the auger (2) is supported on the auger support frame (5), the auger support frame (5) is placed horizontally above the box body (1) and fixed to the front and rear side walls of the box body (1), four fertilizer discharge ports (4) are provided at the bottom of the box body (1), the DC motor (6) is connected to the motor driver (7) and is installed on the same side of the box body (1); one end of the motor driver (7) is connected to the DC motor (6) and the other end is connected to the external power supply device.

[0012] The auger (2) is provided with four blades (10), which are symmetrically arranged on the auger (2) shaft. The rotation direction of the two blades (10) close to the motor side is opposite to the rotation direction of the two blades (10) away from the motor side. The fertilizer discharge port (4) is provided at the disconnection point of the four blades so that the fertilizer pushed by the auger (2) blades (10) can be discharged in time; the fertilizer cleaning brush (3) is connected to the brush base (8), and the brush base (8) is fixed on the auger (2) blades (10). The brush base (8) and the auger blades are provided with corresponding brush fixing holes (9), and the fertilizer cleaning brush is fixed to the blades by bolt connection.

[0013] Compared with the existing technology, the beneficial effects of the utility model are: the rotation of the auger can open up the compacted fertilizer, ensure smooth fertilizer discharge, the fertilizer box improves the utilization rate of the fertilizer, the blade brush can clean the fertilizer accumulation at the corners of the box to a greater extent, solve the problem of fertilizer accumulation at the bottom, and simplify the cleaning and maintenance of the fertilizer box.

[0014] When the seed drill is in operation, the fertilizer box (1) must be filled with fertilizer first, and the motor driver (7) is started to activate the DC motor (6), thereby driving the auger (2) to rotate.
