[0014] Figure 2 for Figure 1 Schematic diagram of the three-dimensional structure of the fertilizer feeding device. DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, the fertilizer spreader with automatic fertilizer application speed adjustment of the present invention comprises a running wheel 10 and a lower hopper 20. There are three running wheels 10, which are distributed in a triangle shape, the front wheels are guide wheels, and the rear two wheels are driving wheels. A rotating shaft 11 is provided on the running wheel 10, and the running wheel 10 is driven by the rotating shaft 11. The lower hopper 20 is fixed on a frame 21, and a fertilizer device 30 is connected to the discharge port at the lower end of the lower hopper 20.

[0016] like Figure 1 and Figure 2 As shown, a rotating shaft 6 is provided on the fertilizer delivery device 30, and the rotating shaft 6 is connected to a chain 14, and the other end of the chain 14 is connected to the rotating shaft 11 of the walking wheel 10. The rotating shaft 6 on the fertilizer delivery device 30 keeps synchronous movement with the rotating shaft 11 of the walking wheel 10, that is, the rotating shaft 11 of the walking wheel 10 drives the rotating shaft 6 on the fertilizer delivery device 30 to rotate through the chain 14.

[0017] like Figure 1 and Figure 2As shown, the fertilizer dispensing device 30 includes a bottom plate 1, which is fixed to the bottom end of the dispensing hopper 20, and is used to fix and install the fertilizer dispensing device 30. A dispensing port 2 is provided on the bottom plate 1, and the dispensing port 2 is connected with the dispensing port of the dispensing hopper 20, and the material is discharged from the dispensing port of the dispensing hopper 20 and enters the dispensing port 2. A sealing plate 3 is matched on the dispensing port 2, and the sealing plate 3 is arranged at the lower end of the bottom plate 1. The dispensing port 2 can be sealed by pushing the sealing plate 3, and the dispensing port 2 can be opened by pulling the sealing plate 3. The sealing plate 3 is connected to the joystick 16, and the opening and closing of the sealing plate 3 is controlled by the joystick 16, and the joystick 16 is arranged at the driver's seat.

[0018] like Figure 1 and Figure 2 As shown, a casing 4 is fixed at the lower end of the bottom plate 1, and a rotating cylindrical bucket 5 is provided in the casing 4. The rotating cylindrical bucket 5 can be driven to rotate by a rotating shaft 6, and the rotating shaft 6 is connected to the rotating shaft 11 of the walking wheel 10 through a chain 14, so that the rotation speed of the rotating shaft 6 is synchronized with the walking speed of the walking wheel 10, that is, the faster the fertilizer spreader moves, the faster the rotating cylindrical bucket 5 rotates.

[0019] like Figure 1 As shown, the rotary feeding cylinder bucket 5 is provided with a grid of charging bins 51, each of which is separated from the other, and all of the charging bins 51 form a cylindrical shape, that is, the entire rotary feeding cylinder bucket 5 is evenly divided into a plurality of charging bins 51, each of which has the same volume and structure, and each of which is separated from the other by a board. The outer end of the rotary feeding cylinder bucket 5 is matched with an adjusting cover 7, which is also cylindrical, that is, the adjusting cover 7 is sleeved on the outside of the rotary feeding cylinder bucket 5, one end of the adjusting cover 7 is connected to a rotating buckle 8, and the rotating buckle 8 is matched on the rotating shaft 6. The adjusting cover 7 is rotated by the rotating buckle 8 to adjust the position, that is, when the adjusting cover 7 rotates inward, the adjusting cover 7 also moves inward, so that the adjusting cover 7 can cover more charging bins 51, thereby adjusting the charging amount of the charging bins 51, so as to meet the fertilizer demand of different crops. A brush 9 is also provided at the outer end of the charging bin 51, and the brush 9 is fixed in the housing 4. The brush 9 cooperates with the charging bin 51. Since the charging bin 51 can rotate in the housing 4, there is a certain gap between the charging bin 51 and the housing 4, and the brush 9 just blocks the gap, which does not affect the free rotation of the charging bin 51, and prevents the fertilizer in the charging bin 51 from leaking out. A fertilizer pipe 15 is provided at the lower end of the fertilizer dispensing device 30, and the fertilizer pipe 15 is fixed at the lower end of the housing 4. The fertilizer pipe 15 cooperates with the charging bin 51. After the charging bin 51 rotates downward, the fertilizer in the charging bin 51 automatically falls down under the action of gravity, and then falls into the fertilizer pipe 15, and falls from the fertilizer pipe 4 to the ground.

[0020] To sum up, compared with the prior art, the fertilizer spreader with automatic adjustment of fertilization speed of the present invention maintains synchronous movement through the rotating shaft of the walking wheel and the rotating shaft on the fertilizer dispensing device, so that the walking speed of the walking wheel and the fertilizer dispensing speed of the fertilizer dispensing device are kept synchronously running. The faster the walking wheel moves, that is, the faster the fertilizer spreader moves, the faster the fertilizer dispensing speed of the fertilizer dispensing device is. Similarly, the slower the fertilizer spreader moves, the slower the fertilizer dispensing speed of the fertilizer dispensing device is. This can ensure uniform fertilization at any walking speed.
