Description

Technical Field

[0001] This utility model relates to a rotary tiller, specifically an adjustable fertilizer rotary tiller for intercropping, belonging to the field of agricultural equipment technology. Background Technology

[0002] Rotary tillers are agricultural machines used in conjunction with tractors to perform tilling and harrowing operations. They are widely used due to their strong soil-breaking ability and the ability to create a flat surface after tilling; they can also chop up stubble buried below the surface, facilitating seeder operations and providing a good seedbed for later sowing. Based on the configuration of their rotary tiller shafts, they are divided into two types: horizontal shaft type and vertical shaft type.

[0003] A search revealed a Chinese patent with publication number CN218353079U that discloses an adjustable fertilizing rotary tiller for intercropping. This utility model, by setting a rotary tiller unit and an electric fertilizing mechanism on the frame, has greater adaptability and realizes the combined functions of fertilizing across the seedling belt and rotary tilling operations in intercropping, effectively reducing the number of times the unit needs to be in the field and greatly improving operating efficiency.

[0004] While the above-mentioned scheme allows for simultaneous fertilization and rotary tillage, some compound fertilizers and phosphate fertilizers tend to clump together during the fertilization process. If the fertilizers are not broken up in time, this can easily cause blockages in the fertilization mechanism, resulting in uneven fertilization and low fertilization quality. To address this issue, we provide an adjustable fertilization rotary tiller for intercropping to solve the above problems. Utility Model Content

[0028] This utility model embodiment provides an adjustable fertilizer rotary tiller for intercropping.

[0029] Please see Figure 1It includes a tiller body 1, which has a power supply installed inside, which can supply power to the electrical equipment in this application.

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The tiller body 1 is equipped with a grinding and feeding mechanism 2. The grinding and feeding mechanism 2 includes a first drive rod 201. A first driven bevel gear 202 is slidably connected to the outer surface of the first drive rod 201. A slot is opened on the outer surface of the first drive rod 201. A locking block that matches the slot on the surface of the first drive rod 201 is fixedly installed on the inner wall of the first driven bevel gear 202. So when the first drive rod 201 rotates, it can drive the first driven bevel gear 202 to rotate at the same time. By moving the drive adjustment frame 208, the first driven bevel gear 202 can be moved simultaneously on the outer surface of the first drive rod 201.

[0031] The outer surface of the first driven bevel gear 202 is meshed with the second driven bevel gear 203. The outer surface of the second driven bevel gear 203 is fixedly connected to the rotating rod 204. The outer surface of the rotating rod 204 is slidably connected to the tiller body 1. The outer surface of the rotating rod 204 is fixedly connected to the grinding roller 205. By driving the second driven bevel gear 203 to drive the grinding roller 205 to rotate, the fertilizer in the tiller body 1 can be ground, effectively preventing the fertilizer from clumping and causing the device to become blocked.

[0032] A protective box 206 is fixedly connected to the outer surface of the tiller body 1. The inner wall of the protective box 206 is rotatably connected to the first drive rod 201. A drive motor 1 and a drive motor 2 are fixedly installed on the inner wall of the protective box 206. A sprocket is fixedly installed at the output end of the motor 1. The outer surface of the sprocket meshes with the transmission chain 211. The output end of the motor 2 is fixedly connected to the first drive rod 201. By setting up the protective box 206, the motor and the components in the grinding and feeding mechanism 2 can be protected, preventing external dust from entering the motor and components and affecting normal operation.

[0033] The inner wall of the protective box 206 is rotatably connected to a bidirectional adjusting screw 207, and the outer surface of the bidirectional adjusting screw 207 is threadedly connected to an adjusting frame 208. The inner wall of the adjusting frame 208 is slidably connected to the first driving rod 201, and the inner wall of the adjusting frame 208 is rotatably connected to the rotating rod 204. The outer surface of the adjusting frame 208 is rotatably connected to the first driven bevel gear 202. By driving the adjusting frame 208 to move, the first driven bevel gear 202 and the rotating rod 204 can be driven to move simultaneously, effectively adjusting the grinding gap between the two grinding rollers 205, enabling the device to handle the crushing of different types of fertilizers, and greatly improving the flexibility of the device.

[0034] A limiting plate 209 is fixedly connected to the inner wall of the tiller body 1. A connecting shaft 210 is rotatably connected to the inner wall of the limiting plate 209. A bearing is fixedly installed between the limiting plate 209 and the connecting shaft 210. The outer ring of the bearing is fixedly connected to the limiting plate 209, and the inner ring of the bearing is fixedly connected to the outer surface of the connecting shaft 210. The bearing effectively limits the connecting shaft 210. A sprocket is fixedly installed at the end of the connecting shaft 210 away from the auger conveyor roller 213. The sprocket meshes with the transmission chain 211, so that when the motor inside the protective box 206 is opened, multiple connecting shafts 210 can be driven to rotate simultaneously.

[0035] One end of the connecting shaft 210 is connected to the transmission chain 211 via a sprocket drive. The inner wall of the tiller body 1 is fixedly connected to the fertilizer guide pipe 212. The tiller body 1 provides support and fixation for the fertilizer guide pipe 212. The bottom end of the fertilizer guide pipe 212 has a leakage hole, through which fertilizer in the fertilizer guide pipe 212 can fall into the soil.

[0036] The inner wall of the fertilizer guide tube 212 is rotatably connected to an auger conveyor roller 213. One end of the auger conveyor roller 213 is fixedly connected to the connecting shaft 210. By driving the auger conveyor roller 213 to rotate, fertilizer can be pushed to move evenly and in equal amounts inside the fertilizer guide tube 212.

[0037] Please refer to it again. Figure 1 and Figure 5 The tiller body 1 is equipped with a tillage mechanism 3, which includes a tillage blade 301. A second drive rod 302 is fixedly connected to the inner wall of the tillage blade 301. An adjustment plate 303 is rotatably connected to both ends of the second drive rod 302. The outer surface of the adjustment plate 303 is slidably connected to the tiller body 1. A drive device is installed inside the adjustment plate 303. By turning on the drive device, the second drive rod 302 can be effectively driven to rotate.

[0038] An electric push rod 304 is fixedly connected to the inner top wall of the tiller body 1. A connecting plate 305 is fixedly connected to the telescopic end of the electric push rod 304. The bottom surface of the connecting plate 305 is fixedly connected to the adjusting plate 303. By opening the electric push rod 304 to extend and retract it, the tillage blade 301 moves up and down, so that the device can freely adjust the tillage depth of the tillage blade 301 according to the needs, further making the device more practical.

[0039] The drive motor 1, drive motor 2, drive equipment and electric actuator 304 mentioned in this application are all common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

[0040] In use, this invention works as follows: First, by operating the electric actuator 304 as needed, it extends and retracts, causing the adjusting plate 303 on the bottom surface of the connecting plate 305 to slide up and down within the inner wall of the tiller body 1. The up-and-down movement of the adjusting plate 303 causes the tillage blades 301 on the surface of the second drive rod 302 to move up and down, effectively adjusting the tillage depth. During the fertilization process, the drive device is activated to rotate the first drive rod 201. The rotation of the first drive rod 201 causes the first driven bevel gear 202 to rotate, which in turn causes the rotating rod 204 on the surface of the second driven bevel gear 203 to rotate. The rotation of the rotating rod 204 causes the grinding roller 205 to effectively grind the fertilizer, preventing fertilizer from clumping in the tiller body 1. The ground fertilizer falls into the bottom of the tiller body 1. At the same time, the drive equipment and the transmission chain 211 are activated, so that multiple connecting shafts 210 rotate in the same direction. The rotation of the connecting shafts 210 drives the auger conveyor roller 213 to rotate. The rotation of the auger conveyor roller 213 pushes the ground fertilizer at the bottom of the tiller body 1 into the fertilizer guide pipe 212. The fertilizer falls into the soil through the hole at the bottom of the fertilizer guide pipe 212. Thus, this device can grind the fertilizer and spread it evenly and in equal amounts to the tilled soil through the auger conveyor roller 213. This effectively avoids the clogging of the device due to the clumping of some compound fertilizers and phosphate fertilizers, which would lead to uneven fertilization. This further greatly improves the quality of fertilization.
