Description

Technical Field

[0001] This utility model relates to the field of seeders, and in particular to a seeder with adjustable spacing. Background Technology

[0002] A seeder is used for sowing crops. It consists of a mounting frame, connectors, seed box, connecting pipe, seeding cylinder, and tillage blades. When using the seeder, the mounting frame is fixed to the agricultural machine through the connectors and pins. The seed box is filled with seeds. When the agricultural machine moves in the field, the tillage blades till the field. The valve is opened, allowing the seeds to enter the seeding cylinder through the connecting pipe and then fall into the tilled field, thus completing the sowing.

[0003] The inventors discovered in their daily work that when using a seeder, the fixed distance between the seeding cylinders makes it difficult to sow seeds at large or small intervals, which may result in low seeding spacing suitability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, the fixed distance between the seeding cylinders on the seeder makes it difficult to sow at large or small spacings, which may lead to low adaptability of the sowing spacing. Therefore, an adjustable spacing seeder is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable spacing seeder, including a mounting frame, a seed box fixedly connected to the upper end of the mounting frame, a connector fixedly connected to the back of the mounting frame, an adjustment component provided at the upper end of the mounting frame, a seeding cylinder, a tiller, and a replacement component provided on the front of the mounting frame, a connecting pipe fixedly connected between the seeding cylinder and the seed box, the adjustment component including a second sliding block fixedly connected to one side of the mounting frame, a square sliding rod fixedly connected between the second sliding block and the mounting frame, a first sliding block slidably connected to the surface of the square sliding rod, a connecting rod fixedly connected between the first sliding block and the seeding cylinder, a pushing mechanism provided at the right end of the rightmost first sliding block, a first rotating rod rotatably connected to the front of the first and second sliding blocks, a second rotating rod rotatably connected to the front of the first rotating rod, the left first rotating rod rotatably connected to the right second rotating rod, and the left second rotating rod rotatably connected to the right first rotating rod.

[0006] The effect achieved by the above components is as follows: by setting the adjustment component, when it is necessary to adjust the sowing spacing, the rightmost first sliding block is pushed by the pushing mechanism, while the second sliding block is fixed to the mounting frame. When the first sliding block is pushed, the first rotating rod and the second rotating rod rotate, thereby moving the remaining first sliding blocks. This causes the sowing cylinder connected to the connecting rod to move accordingly, thereby adjusting the sowing spacing and thus maximizing the adaptability of the sowing spacing.

[0007] Preferably, the pushing mechanism includes a lead screw fixedly connected to the right end of the rightmost first sliding block, and a mounting plate is fixedly connected to the upper end of the mounting bracket.

[0008] The effect achieved by the above components is that the lead screw on the mounting plate is pushed, which in turn pushes the rightmost first sliding block.

[0009] Preferably, the lead screw passes through the mounting plate, and a first gear and a second gear are rotatably connected to the left end of the mounting plate. The first gear and the second gear mesh with each other, and the lead screw and the first gear are threadedly connected.

[0010] The effect achieved by the above components is that the second gear rotates through the drive mechanism, which in turn causes the first gear to rotate, thereby pushing the lead screw on the mounting plate.

[0011] Preferably, a motor is mounted on the right end of the mounting plate, and the output end of the motor and the second gear are fixed.

[0012] The effect achieved by the above components is to start the motor, which, in conjunction with the encoder, causes the second gear to rotate.

[0013] Preferably, the replacement component includes a fixed mounting frame fixedly connected to the lower end of the first sliding block, the tiller blade is inserted into the fixed mounting frame, and triangular blocks are slidably inserted at both ends of the tiller blade.

[0014] The effect achieved by the above components is as follows: when it is necessary to replace the tiller blade, the pulling mechanism is used to pull the triangular block back into the tiller blade, then the tiller blade is dragged to separate from the fixed mounting frame, and then a new tiller blade is inserted to complete the replacement.

[0015] Preferably, the triangular block is inserted into the fixed mounting frame, and a spring is fixedly connected to the right end of the triangular block.

[0016] The effect achieved by the above components is to reset the triangular block by setting a spring.

[0017] Preferably, the other end of the spring is fixed to the tiller blade, and the right end of the triangular block is fixedly connected to a pull rope.

[0018] The effect achieved by the above components is that pulling the rope causes the triangular block to be pulled.

[0019] Preferably, the pull rope passes through the tiller blade, and the other end of the pull rope is located on the surface of the tiller blade.

[0020] The effect achieved by the above components is that pulling the rope causes the triangular block to be pulled, and at the same time the spring deforms.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting an adjustment component, when the sowing spacing needs to be adjusted, the rightmost first sliding block is pushed by the pushing mechanism, while the second sliding block is fixed to the mounting frame. When the first sliding block is pushed, the first rotating rod and the second rotating rod rotate, thereby moving the remaining first sliding blocks. This causes the sowing cylinder connected to the connecting rod to move accordingly, thereby adjusting the sowing spacing and maximizing the adaptability of the sowing spacing. This solves the problem that the fixed distance between the sowing cylinders on the seeder makes it difficult to sow at large or small spacings, which may result in low adaptability of the sowing spacing.

[0028] Reference Figure 1 and Figure 3As shown, this utility model provides a technical solution: an adjustable spacing seeder includes a mounting frame 1, a seed box 4 is fixedly connected to the upper end of the mounting frame 1, a connector 8 is fixedly connected to the back of the mounting frame 1, an adjustment component 2 is provided at the upper end of the mounting frame 1, a seeding cylinder 5, a tiller blade 7, and a replacement component 3 are provided on the front of the mounting frame 1, and a connecting pipe 6 is fixedly connected between the seeding cylinder 5 and the seed box 4.

[0029] The following section will explain the specific settings and functions of adjusting component 2 and replacing component 3.

[0030] Reference Figure 2 As shown in this embodiment: the adjusting component 2 includes a second sliding block 25 fixedly connected to one side of the mounting frame 1. A square sliding rod 21 is fixedly connected between the second sliding block 25 and the mounting frame 1. A first sliding block 22 is slidably connected to the surface of the square sliding rod 21. A connecting rod 23 is fixedly connected between the first sliding block 22 and the seeding cylinder 5. A pushing mechanism 24 is provided at the right end of the rightmost first sliding block 22. A first rotating rod 26 is rotatably connected to the front of the first sliding block 22 and the second sliding block 25. A second rotating rod 27 is rotatably connected to the front of the first rotating rod 26. The left first rotating rod 26 is rotatably connected to the right second rotating rod 27, and the left second rotating rod 27 is rotatably connected to the right first rotating rod 26. By setting the adjusting component 2, when it is necessary to adjust the seeding spacing, the pushing mechanism 24 pushes the rightmost first sliding block 22, while the second sliding block 25 is fixed to the mounting frame 1. This pushes the first sliding block 22, causing the first rotating rod 26 and the second rotating rod 27 to rotate simultaneously, thereby adjusting the remaining... A sliding block 22 moves, causing the seeding cylinder 5 connected to the connecting rod 23 to move accordingly, thereby adjusting the seeding spacing and maximizing the adaptability of the seeding spacing. The pushing mechanism 24 includes a lead screw 241 fixedly connected to the right end of the rightmost first sliding block 22. A mounting plate 245 is fixedly connected to the upper end of the mounting frame 1. When the lead screw 241 on the mounting plate 245 is pushed, the rightmost first sliding block 22 is pushed. The lead screw 241 passes through the mounting plate 245. A first gear 242 and a second gear 243 are rotatably connected to the left end of the mounting plate 245. The first gear 242 and the second gear 243 mesh with each other. The lead screw 241 and the first gear 242 are threadedly connected. Through the driving mechanism, the second gear 243 rotates, causing the first gear 242 to rotate, thereby pushing the lead screw 241 on the mounting plate 245. A motor 244 is installed on the right end of the mounting plate 245. The output end of the motor 244 is fixed to the second gear 243. When the motor 244 is started, it works with the encoder to make the second gear 243 rotate.

[0031] Reference Figure 4As shown in this embodiment: the replacement component 3 includes a fixed mounting frame 31 fixedly connected to the lower end of the first sliding block 22. The tiller blade 7 is inserted into the fixed mounting frame 31. Triangular blocks 32 are slidably inserted at both ends of the tiller blade 7. When the tiller blade 7 needs to be replaced, the triangular blocks 32 are completely pulled back into the tiller blade 7 by a pulling mechanism. Then, the tiller blade 7 is dragged to separate from the fixed mounting frame 31. Then, a new tiller blade 7 is inserted to complete the replacement. The triangular blocks 32 are inserted into the fixed mounting frame 31. A spring 33 is fixedly connected to the right end of the triangular blocks 32. By setting the spring 33, the triangular blocks 32 are reset. The other end of the spring 33 is fixed to the tiller blade 7. A pull rope 34 is fixedly connected to the right end of the triangular blocks 32. Pulling the pull rope 34 causes the triangular blocks 32 to be pulled. The pull rope 34 passes through the tiller blade 7. The other end of the pull rope 34 is located on the surface of the tiller blade 7. Pulling the pull rope 34 causes the triangular blocks 32 to be pulled. At the same time, the spring 33 deforms.

[0032] Working principle:

[0033] When using the seeder, the mounting frame 1 is fixed to the agricultural machinery via the connector 8 and the pin. The seed box 4 is filled with seeds. As the agricultural machinery moves in the field, the tillage blades 7 till the field. The valve is opened, allowing the seeds to enter the seeding cylinder 5 through the connecting pipe 6 and then fall into the tilled field, thus completing the sowing. When it is necessary to adjust the sowing spacing, the motor 244 is started. In conjunction with the encoder, the second gear 243 rotates, causing the first gear 242 to rotate. This pushes the lead screw 241 on the mounting plate 245, which in turn pushes the rightmost first sliding block 22. The second sliding block 25 is fixed to the mounting frame 1, causing the square sliding rod 21 to... The first sliding block 22 is pushed while the first rotating rod 26 and the second rotating rod 27 rotate, thereby moving the remaining first sliding blocks 22. This causes the seeding cylinder 5 connected to the connecting rod 23 to move accordingly, thereby adjusting the seeding spacing and maximizing the adaptability of the seeding spacing. When it is necessary to replace the tiller 7, the pull rope 34 is pulled, causing the triangular block 32 to be pulled. At the same time, the spring 33 deforms, causing the triangular block 32 to be completely pulled back into the tiller 7. Then, the tiller 7 is dragged to separate from the fixed mounting frame 31, and then a new tiller 7 is inserted to complete the replacement. The triangular block 32 is reset by setting the spring 33.
