Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, and in particular to a rotary tillage, fertilization, sowing, and compaction self-rotating device. Background Technology

[0002] Rotary tillers are agricultural machinery that cuts and turns soil by rotating blades. They are characterized by strong soil breaking ability and smooth surface. They are widely used in paddy fields, dry land, and orchards for tillage, stubble removal, and land preparation. They can complete the effect of plowing and harrowing multiple times in one operation, thus improving agricultural production efficiency.

[0003] When using a rotary tiller for sowing, to prevent the seeds from being eroded by the wind, a layer of soil is covered on top of the sown seeds. Existing rotary tillers can achieve this purpose, such as the compaction device of a seeder disclosed in patent announcement CN209089375U, which can use a hydraulic cylinder to make the compaction wheel have sufficient true pressure to compact the soil and prevent the seeds from being eroded by the wind.

[0004] However, this solution still has a problem: the roller itself is not powered and cannot rotate. Therefore, after prolonged contact with the soil, soil will adhere to the surface of the roller. As the amount of soil increases, the friction between the roller and the ground will increase. When moving, it will carry soil with it, making it unable to flatten the soil after cultivation. As a result, the seeds still have a high possibility of being eroded by the wind. Utility Model Content

[0005] The main purpose of this utility model is to provide a rotary tillage, fertilization, sowing, and compaction self-rotating device. When the cutter shaft rotates, it can apply power to the compaction roller through the transmission component, thereby causing the compaction roller to rotate on its own. This avoids excessive soil adhering to the surface of the compaction roller during use, ensuring that the compaction roller can flatten the soil after tillage and reduce the possibility of seeds being eroded by wind.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rotary tillage, fertilization, sowing, and pressing self-rotating device includes a rotary tiller and a pressing roller. A transmission component is rotatably connected to the frame of the rotary tiller. The cutter shaft of the rotary tiller is fixedly connected to the power input end of the transmission component. The pressing roller is fixedly connected to the power output end of the transmission component. The device also includes a linear drive device, with its two ends rotatably connected to the frame and the transmission component, respectively.

[0008] Furthermore, the transmission assembly includes two sets of oppositely arranged fixed plates, with a drive gear and a driven gear rotatably connected between the two fixed plates. A plurality of transmission gears are arranged between the drive gear and the driven gear, and the plurality of transmission gears are rotatably connected to the fixed plates. The drive gear, the plurality of transmission gears, and the driven gear mesh sequentially.

[0009] Furthermore, the transmission assembly is rotatably connected to the frame via a rotating assembly.

[0010] Furthermore, the rotating assembly includes a bearing, which is fixed to a fixed plate near the frame. A rotating shaft is fixed to the inner ring of the bearing. A through hole is opened on one side surface of the rotating shaft, and a first shaft body is disposed in the through hole. One end of the first shaft body is fixedly connected to the cutter shaft, and the other end is fixedly connected to the drive gear.

[0011] Furthermore, one end of the pressing roller is fixedly connected to the driven gear via a second shaft, and the other end of the pressing roller is rotatably connected to a positioning plate, which is fixedly connected to the frame.

[0012] Furthermore, the linear drive device is a hydraulic cylinder.

[0013] Furthermore, the two sets of fixing plates are fixedly connected by bolts.

[0014] Furthermore, the connection end between the linear drive device and the frame is higher than the connection end between the linear drive device and the transmission assembly.

[0015] Furthermore, the rotation center line of the rotating shaft and the rotation center line of the first shaft are located on the same straight line.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the cutter shaft of this invention rotates, it can apply power to the pressing roller through the transmission component, thereby causing the pressing roller to rotate on its own. This prevents a lot of soil from adhering to the surface of the pressing roller during use, ensuring that the pressing roller can flatten the soil after cultivation and reduce the possibility of seeds being eroded by the wind.

[0018] When the length of the linear drive device of this invention is changed, the height of the press roller will change, thus making it easier for personnel to determine the height of the press roller according to the on-site conditions of the cultivated land.

[0019] The rotation center of the first shaft of this invention coincides with the rotation center of the rotating shaft. Therefore, when the transmission assembly rotates based on the first shaft, the position of the drive gear relative to the frame will not change, thus ensuring that the power transmission of the transmission assembly will not be affected.

[0020] The positioning plate of this invention, in conjunction with the transmission assembly, can ensure the positional stability of the pressing roller while allowing it to rotate. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-3 As shown, a rotary tillage, fertilization, sowing, and pressing self-rotating device includes a rotary tiller 1 and a pressing roller 4. A transmission component 3 is rotatably connected to the frame 101 of the rotary tiller 1. The cutter shaft 102 of the rotary tiller 1 is fixedly connected to the power input end of the transmission component 3, and the pressing roller 4 is fixedly connected to the power output end of the transmission component 3. When the cutter shaft 102 rotates, it can drive the pressing roller 4 to rotate through the transmission component 3. The device also includes a linear drive device 2, with both ends of the linear drive device 2 rotatably connected to the frame 101 and the transmission component 3, respectively.

[0027] In this embodiment, such as Figure 1As shown, the connection end between the linear drive device 2 and the frame 101 is higher than the connection end between the linear drive device 2 and the transmission assembly 3. The linear drive device 2 is a hydraulic cylinder. When the rotary tiller 1 is working, the linear drive device 2 applies a downward force to the press roller 4, so that the press roller 4 can flatten the ground. When the cutter shaft 102 of the rotary tiller 1 rotates, it can apply power to the press roller 4 through the transmission assembly 3, so that the press roller 4 rotates itself, thereby avoiding the surface of the press roller 4 from having too much soil adhering to it during use, ensuring that the press roller 4 can flatten the soil after tilling and reducing the possibility of seeds being eroded by the wind.

[0028] When the height of the pressing roller 4 needs to be adjusted, the linear drive device 2 can be controlled to work. Since the two ends of the linear drive device 2 are rotatably connected to the frame 101 and the transmission assembly 3 respectively, the height of the pressing roller 4 will change when the length of the linear drive device 2 changes, so as to meet the usage requirements.

[0029] like Figure 2 As shown, the transmission assembly 3 includes two sets of opposing fixed plates 301. A drive gear 302 and a driven gear 304 are rotatably connected between the two fixed plates 301. A plurality of transmission gears 303 are arranged between the drive gear 302 and the driven gear 304. The plurality of transmission gears 303 are rotatably connected to the fixed plates 301. The drive gear 302, the plurality of transmission gears 303 and the driven gear 304 mesh in sequence. One end of the pressing roller 4 is fixedly connected to the driven gear 304 through the second shaft 8. When the cutter shaft 102 rotates, it will drive the drive gear 302 to rotate. The drive gear 302 drives the driven gear 304 to rotate through the plurality of driven gears 304, thereby driving the pressing roller 4 to rotate to complete the transmission operation.

[0030] The transmission assembly 3 is rotatably connected to the frame 101 via the rotating assembly 5.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the rotating assembly 5 includes a bearing 501, which is fixed on a fixed plate 301 close to the frame 101. A rotating shaft 502 is fixed to the inner ring of the bearing 501. The rotating shaft 502 is fixedly connected to the frame 101, so the transmission assembly 3 can rotate relative to the frame 101. Thus, when the linear drive device 2 is working, the transmission assembly 3 can rotate at a certain required angle.

[0032] Furthermore, a through hole 5022 is provided on one side surface of the rotating shaft 502, and a first shaft body 7 is provided inside the through hole 5022. The diameter of the through hole 5022 is larger than the diameter of the first shaft body 7, so the through hole 5022 will not interfere with the rotation of the first shaft body 7. One end of the first shaft body 7 is fixedly connected to the cutter shaft 102 and the other end is fixedly connected to the drive gear 302. Therefore, when the cutter shaft 102 rotates, the cutter shaft 102 can drive the drive gear 302 to rotate through the first shaft body 7.

[0033] Both the fixed plate 301 and the frame 101 are provided with through holes that match the first shaft 7 and the second shaft 8. Therefore, the rotation of the first shaft 7 and the second shaft will not be hindered after passing through the corresponding through holes.

[0034] When the linear drive device 2 operates to drive the transmission assembly 3 to rotate, the drive gear 302 can rotate relative to the fixed plate 301. The drive gear 302 is connected to the cutter shaft 102 through the first shaft 7, and the rotation center of the first shaft 7 coincides with the rotation center of the rotating shaft 502. Therefore, when the transmission assembly 3 rotates based on the first shaft 7, the position of the drive gear 302 relative to the frame 101 will not change, so as to ensure that the power transmission of the transmission assembly 3 will not be affected.

[0035] The other end of the pressing roller 4 is rotatably connected to a positioning plate 6. The positioning plate 6 is fixedly connected to the frame 101. The positioning plate 6, in conjunction with the transmission component 3, can ensure the positional stability of the pressing roller 4 while allowing it to rotate. The two sets of fixing plates 301 are fixedly connected by bolts.

[0036] The working principle is as follows: First, the cutter shaft 102 of the rotary tiller 1 drives the blades to rotate, turning over the soil. Then, the seeding device of the rotary tiller 1 sows the seeds (this is existing technology and will not be elaborated on here). As the rotary tiller 1 moves, the press roller 4 moves to the soil position where the seeds were sown. Since the cutter shaft 102 of the rotary tiller 1 can apply power to the press roller 4 through the transmission component 3 when rotating, the press roller 4 can rotate itself. Therefore, the press roller 4 can flatten the turned soil while rotating, thereby avoiding excessive soil adhering to the surface of the press roller 4 during use. This ensures that the press roller 4 can flatten the soil after tilling, reducing the possibility of seeds being eroded by wind. Furthermore, the height of the press roller 4 can be adjusted through the linear drive device 2, allowing the operator to determine the height of the press roller 4 according to the specific conditions of the tilled land to meet the usage requirements.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
