The device operates by first bevel gear driving second bevel gear, which in turn drives drive shaft. The storage hopper provides movable support for drive shaft, facilitating the rotation of the spiral blades. This allows the spiral blades to transport fertilizer from the storage hopper through the feed pipe, discharge pipe, and telescopic pipe to the soil surface after being tilled by multiple sets of plowing claws. This facilitates convenient fertilization of crops, enabling rapid and efficient application of fertilizer to multiple crops simultaneously, improving soil tillage efficiency, and enhancing overall crop fertilization effectiveness.

[0019] When the position of the telescopic tube needs to be adjusted, manually rotate the fixing bolt to loosen the gasket and the telescopic tube. Then, manually push the telescopic tube, which, with the sliding support of the discharge pipe, moves it to the appropriate position. Once the telescopic tube is in the correct position, manually rotate the fixing bolt again to tighten the gasket and the telescopic tube, thus easily securing the telescopic tube. This allows for convenient height adjustment of the fertilizer application position, preventing interference from rough terrain during movement and improving the ease of application.

[0020] When the fertilizing device is moving to apply fertilizer, the spring elastically drives the drive block to move. The drive block drives the tilting frame to rotate elastically around the transmission shaft via the power shaft. The tilting frame elastically drives the drive arm to rotate via the hinge shaft. The drive arm drives the covering claw body to rotate elastically, which facilitates close elastic contact between the covering claw body and the soil. This allows the covering claw body to easily cover the fertilized land with soil, thus improving the effectiveness of the fertilizing device in covering the soil. Attached Figure Description

On the outside of the hopper 19, the surface of the drive shaft 17 near the first bevel gear 16 is fitted with a second bevel gear 18, and the second bevel gear 18 meshes with the drive shaft 17. The top of the storage hopper 19 on the side of the drive shaft 17 is provided with a feed port 27, and the bottom of the storage hopper 19 is provided with a discharge pipe 20. The bottom of the discharge pipe 20 is provided with a mechanical valve 21. The inside of the storage hopper 19 on the side of the drive shaft 17 is provided with a spiral blade 28, and the spiral blade 28 is connected to the drive shaft 17 and extends into the inside of the discharge pipe 20.

[0032] The support frame 1 is connected to the external tractor via the traction frame 2. When fertilization of crops is required, fertilizer is poured into the interior of multiple storage hoppers 19 through the feed inlet 27. Multiple mechanical valves 21 are manually opened.

[0033] Multiple sets of fixed frames 7 provide movable support for the rotating shaft 15, facilitating the rotation of the rotating shaft 15 to drive multiple sets of first bevel gears 16 to rotate. Under the meshing of multiple sets of first bevel gears 16 and second bevel gears 18, the first bevel gears 16 drive the second bevel gears 18 to rotate, and the second bevel gears 18 drive the drive shaft 17 to rotate. The storage hopper 19 provides movable support for the drive shaft 17, facilitating the rotation of the spiral blade 28 by the drive shaft 17.

This enables convenient and rapid fertilization of agricultural crops by the fertilization device, facilitating the fertilization of multiple crops at once, facilitating convenient soil turning, and improving the efficiency of crop fertilization.

[0034] The bottom of each mechanical valve 21 is equipped with a discharge pipe 22. A telescopic pipe 23 is slidably fitted on the surface of each discharge pipe 22.

[0035] When the position of the telescopic tube 23 needs to be adjusted, the fixing bolt 25 is manually rotated to loosen the gasket 24, and the telescopic tube 23 is also loosened. The telescopic tube 23 is then manually pushed, and with the sliding support of the discharge pipe 22, it is moved to the appropriate position. The sliding groove 26 provides sliding support for the fixing bolt 25. After the telescopic tube 23 is adjusted to the appropriate position, the fixing bolt 25 is manually rotated again to loosen the gasket 24, and the gasket 24 is tightened, thus facilitating the easy fixing of the telescopic tube 23. This allows for convenient height adjustment of the fertilizer application position by the fertilizing device, avoiding interference caused by rough terrain during movement and improving the convenience of fertilization.

[0036] A drive shaft 29 is installed on the outer wall of the tilting frame 9 near the limit frame 8, and the limit frame 8 is movably connected to the tilting frame 9 through the drive shaft 29. A hinge shaft 33 is installed on the outer wall of the tilting frame 9 near the drive arm 10, and the tilting frame 9 is connected to the drive arm 10 through the hinge shaft 33. A drive rod 34 is slidably installed on the top of the limit frame 8, and a spring 30 is fitted on the surface of the drive rod 34.

The drive block 31 drives the tilting frame 9 to rotate elastically about the transmission shaft 29 via the power shaft 32. The tilting frame 9 elastically drives the drive arm 10 to rotate via the hinge shaft 33. The drive arm 10 drives the soil covering claw body 11 to rotate elastically, so as to facilitate the close elastic contact between the soil covering claw body 11 and the soil, and to facilitate the soil covering claw body 11 to conveniently cover the fertilized land. This realizes the fertilizing device to conveniently cover the fertilized land, facilitates the close elastic contact between the soil covering claw and the soil, and improves the soil covering effect of the fertilizing device.

[0038] The working principle of the technical solution provided by this utility model is as follows: Fertilizer is poured into the interior of multiple storage hoppers 19 through the feed inlet 27. Multiple mechanical valves 21 are manually opened. An external tractor drives the support frame 1 to move via the traction frame 2. The moving wheels 5 rotate on the ground to provide movable support for the support frame 1, facilitating the movement of multiple plowing claws 6 by the support frame 1, thus facilitating the turning of the soil by the multiple plowing claws 6. At the same time, the moving wheels 5 drive the limiting shaft 4 to rotate during rotation, which in turn drives the drive pulley 12 to rotate. The drive pulley 12 then drives the belt 13 to move. 13 drives the driven pulley 14 to rotate, which in turn drives the rotating shaft 15 to rotate. This facilitates the rotating shaft 15 driving multiple sets of first bevel gears 16 to rotate. The first bevel gears 16 drive the second bevel gears 18 to rotate, and the second bevel gears 18 drive the drive shaft 17 to rotate. The storage hopper 19 provides movable support for the drive shaft 17, allowing the drive shaft 17 to drive the spiral blade 28 to rotate. This facilitates the spiral blade 28 transporting the fertilizer inside the storage hopper 19 through the discharge pipe 20, outlet pipe 22, and telescopic pipe 23 to the soil surface after it has been tilled by multiple sets of plowing claws 6, thus facilitating the... For convenient fertilization of crops, when the position of the telescopic tube 23 needs to be adjusted, the fixing bolt 25 is manually rotated to loosen the gasket 24, thus loosening the telescopic tube 23. The telescopic tube 23 is then manually pushed, and with the sliding support of the discharge pipe 22, it moves to the appropriate position. Once the telescopic tube 23 is in the correct position, the fixing bolt 25 is manually rotated again to loosen the gasket 24, thus loosening the gasket 24. The loose state is switched to the locked state to facilitate the easy fixing of the telescopic tube 23. When the fertilizing device is moving to fertilize, the spring 30 elastically drives the drive block 31 to move. The drive block 31 drives the flipping frame 9 to rotate elastically around the transmission shaft 29 via the power shaft 32. The flipping frame 9 elastically drives the drive arm 10 to rotate via the hinge shaft 33. The drive arm 10 drives the soil covering claw body 11 to rotate elastically, so as to facilitate the close elastic contact between the soil covering claw body 11 and the soil, and to facilitate the soil covering claw body 11 to easily cover the fertilized land, thus completing the use of the fertilizing device.
