[0023] As Figures 1 to 5As shown in the figure, a device for replacing the drive wheel of a seeder of the present utility model includes a frame, a rotary tillage assembly 3 disposed inside the frame, a transmission device disposed on the frame for driving the rotary tillage assembly 3 to work, a connecting frame 7 disposed on the frame for connecting with a tractor, longitudinal plates 8 are respectively disposed at both ends of the top surface of the frame, a fertilizing assembly and a seeding assembly are disposed between the two longitudinal plates 8. The soil can be fertilized through the fertilizing assembly, and the soil can be seeded through the seeding assembly. Among them, the fertilizing assembly and the seeding assembly are connected through a first transmission part 17 to realize the work of the fertilizing assembly and the seeding assembly. Fixed frames 14 are disposed at both ends of the frame, a drive wheel is rotatably disposed between the two fixed frames 14, and the drive wheel is detachably connected with the two fixed frames 14. The drive wheel is connected with the first transmission part 17 through a second transmission part 28. When the seeder is working, the drive wheel rotates, and under the action of the first transmission part 17 and the second transmission part 28, it drives the fertilizing assembly to apply fertilizer to the soil surface. The fertilizer falling on the ground is mixed with the soil under the action of the rotary tillage assembly 3, and then the seeding assembly sows the seeds in the grooves opened by the rotary tillage assembly 3 to complete the seeding of the land.

[0024] The above-mentioned frame includes a load-bearing plate 1, vertical plates 2 disposed at both ends of the load-bearing plate 1 and extending downward, a baffle 27 disposed on one side of the load-bearing plate 1, and the rotary tillage assembly 3 is rotatably disposed between the two vertical plates 2. The baffle 27 can block the soil thrown off by the rotary tillage assembly 3 during its operation, and the blocked soil will directly fall into the grooves opened by the rotary tillage assembly 3 to complete the covering of the seeds. The transmission device for connecting the rotary tillage assembly 3 and the power source of the tractor includes a gearbox 4 disposed on the top surface of the load-bearing plate 1, a transmission box 6 disposed on the bottom surface of the load-bearing plate 1 and cooperating with the gearbox 4, and an input shaft 5 rotatably disposed on the gearbox 4. At the same time, the rotary tillage assembly 3 for opening ditches in the soil includes a transmission shaft 31 rotatably disposed between the two vertical plates 2. The transmission shaft 31 passes through the transmission box 6 and cooperates with it to work. A plurality of rotary tillage blades 32 are distributed along the axial direction of the transmission shaft 31. After the tractor is connected to the input shaft 5 on the transmission device, the tractor will drive the gearbox 4 to work through the input shaft 5. When the gearbox 4 is working, it will also drive the transmission box 6 cooperating with it to work. The transmission shaft 31 connected to the transmission box 6 rotates, and drives the plurality of rotary tillage blades 32 disposed thereon to rotate, completing the work of opening ditches in the soil.

A material discharging assembly 13 is rotatably provided at the bottom end of the seed box 9 between the two longitudinal plates 8. A sowing pipe 11 is disposed on the bearing plate 1 on one side of the rotary tillage assembly 3. The sowing pipe 11 is communicated with the material discharging assembly 13 of its corresponding seed box 9 through a connecting pipe. The fertilizing assembly includes a fertilizer box 10 disposed between the two longitudinal plates 8. A material discharging assembly 13 is rotatably provided at the bottom end of the fertilizer box 10 between the two longitudinal plates 8. A fertilizing pipe 12 is disposed on the bearing plate 1 on the other side of the rotary tillage assembly 3. The fertilizing pipe 12 is connected with the material discharging assembly 13 of its corresponding fertilizer box 10 through a connecting pipe. The material discharging assemblies 13 of the fertilizing assembly and the sowing assembly are connected through a first transmission part 17. It should be noted that the fertilizing pipe 12 on the bearing plate 1 is located in front of the rotary tillage assembly 3, while the sowing pipe 11 is located behind the rotary tillage assembly 3. In this way, when the seeder is working, the fertilizer in the fertilizer box 10 will fall into the connecting pipe through the material discharging assembly 13 matched with it, and finally fall on the soil through the fertilizing pipe 12. The fertilizer falling on the soil will be rotated into the soil under the action of the rotary tillage assembly 3, so that the fertilizer can play a better role in the soil. When the rotary tillage assembly 3 rotates and plows the soil to form furrows, the seeds in the seed box 9 will enter the connected connecting pipe under the action of the material discharging assembly 13 matched with it, and finally fall into the furrows opened by the rotary tillage assembly 3 through the sowing pipe 11, and under the action of the rotary tillage blade group 32, the soil and straw on the rotary tillage machine will be mixed and the seeds will be covered with soil.

[0026] Specifically, the material discharging assembly 13 includes a plurality of housing 131 communicated with the bottom ends of the fertilizer box 10 and the seed box 9.

Among them, the sealing mechanism 137 includes mounting rings 1371 provided at both ends of the housing 131. A sealing ring 1372 is rotatably provided in the mounting ring 1371, and a convex block 1373 for cooperating with the loading groove 134 is provided in the sealing ring 1372. The convex block 1373 can be used to prevent the material entering the loading groove 134 from separating from the inside of the housing 131.

Among them, the driving wheel detachably connected to the fixing frame 14 includes a support shaft 15 rotatably provided in the collar 25, a driving roller 16 provided on the support shaft 15. Through the connection of the first connecting plate 23 and the second connecting plate 24, the purpose of detachable connection between the driving wheel and the fixing frame 14 is achieved. Specifically, when the driving wheel needs to be replaced, only the fastening bolt 26 connecting the first connecting plate 23 and the second connecting plate 24 needs to be removed, and then the second connecting plate 24 on the new driving wheel is connected to the first connection at the bottom end of the fixing frame 14 through the fastening bolt 26. The operation is simple and the disassembly and assembly are fast, saving time and improving work efficiency.

[0029] Preferably, the hanging plate 142 and the driving wheel are connected through an adjusting component, and the adjusting component includes a slot 20 opened in the hanging plate 142, a plug rod 21 slidably provided in the slot 20, and a positioning bolt 22 threadedly connected to the side wall of the hanging plate 142.
