Description

Technical Field

[0001] This utility model relates to the field of soil tillage technology, and in particular to a multifunctional agricultural machinery tillage machine. Background Technology

[0002] Multifunctional agricultural tillers are core equipment in modern agricultural production, integrating deep tillage, stubble removal, and weed control. They can flexibly adjust operating parameters according to different soil types and planting needs. Equipped with a high-powered engine and highly wear-resistant operating components, they can handle deep loosening operations on large, compacted soils, breaking up the plow pan and improving soil aeration and water and fertilizer retention. Furthermore, their high-speed rotating blades can pulverize field straw and weeds and mix them into the soil, achieving resource recycling and environmental protection. With its flexible steering system and stable operating performance, it can significantly improve tillage efficiency, laying a solid soil foundation for high and stable yields of subsequent crops. It is a key piece of equipment for promoting the mechanization, intensification, and green development of agriculture.

[0003] Existing multi-functional agricultural tillage machines use arc welding or gas welding to directly weld the cutter head to the cutter shaft or cutter holder, forming a fixed, non-removable structure. This connection method is extremely robust and has no risk of loosening. However, once the cutter head is worn or damaged, it cannot be directly disassembled and replaced. It is necessary to first separate the old cutter head from the cutter shaft or cutter holder by cutting, which consumes additional labor and materials. Current technology uses bolts to directly connect the mounting hole of the cutter head to the threaded hole of the cutter shaft or cutter holder, using the axial force of the bolts to lock the cutter head. However, replacing the cutter head still requires using tools to unscrew the bolts one by one and reinstall them, which is very time-consuming and labor-intensive, reducing the machine's working efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-functional agricultural machinery tiller, which aims to improve the problem that in the existing technology, replacing the cutter head still requires the use of tools to unscrew the bolts one by one and reinstall them, which is very time-consuming and laborious and reduces the machine's working efficiency.

The outer wall of the steel rope is slidably connected to the outer wall of the support column. An alloy buckle is fixedly connected to the rear side of the outer wall of the steel rope. The front end of the alloy buckle is slidably connected to the interior of the rotating shaft, and the rear end of the alloy buckle is slidably connected to the interior of the buckle groove. Multiple high-carbon springs are fixedly connected to the front side of the outer wall of the alloy buckle, and the front sides of the outer walls of each of the high-carbon springs are fixedly connected to the inner wall of the rotating shaft.

[0007] As a further description of the above technical solution: The adjustment mechanism includes multiple connecting columns, all of which are installed at the front end of the machine body. The front side of the outer wall of each connecting column is fixedly connected to the rear side of the outer wall of the weeder. A double rack is fixedly connected to the rear side of the outer wall of each connecting column. A limiting groove is formed in the middle of the double rack. A power component is installed at the top of the double rack. A stabilizing component is installed inside the limiting groove.

[0008] As a further description of the above technical solution: The power assembly includes a drive motor mounted on the top of a double rack. A worm is fixedly connected to the output end of the drive motor. A worm wheel is mounted on the top of the outer wall of the worm. The top of the outer wall of the worm meshes with the bottom of the outer wall of the worm wheel. A support shaft is fixedly connected to the middle of the worm wheel. The left and right sides of the outer wall of the support shaft are rotatably connected to the front end of the machine body. A double gear is fixedly connected to the middle of the outer wall of the support shaft. The front side of the outer wall of the double gear meshes with the rear side of the outer wall of the double rack.

[0009] As a further description of the above technical solution: The stabilizing component includes multiple limiting frames, each of which is installed inside a limiting groove. The middle of the outer wall of each limiting frame is slidably connected to the inside of the limiting groove. A support frame is installed on the outer wall of the drive motor. The inside of the support frame is fixedly connected to the outer wall of the drive motor. The left and right sides of the outer wall of the support frame are fixedly connected to the inside of the front end of the machine body. A protective cover is fixedly connected to the front end of the outer wall of the machine body. The left and right sides of the outer wall of each limiting frame are fixedly connected to the inner wall of the protective cover.

[0013] This utility model has the following beneficial effects: 1. In this utility model, pressing the right front pressing frame moves the steel rope connected to the rear, causing the steel rope to slide along the outer wall of the support column fixed inside the rotating shaft. The steel rope then pulls the rear buckle to slide inside the rotating shaft. At this time, the buckle squeezes the front spring to accumulate elastic potential energy, causing the mounting shaft to slide along the inner wall of the left and right ends of the rotating shaft until the slot aligns with the buckle. After releasing the pressing frame, the spring returns to its original position and pushes the buckle to slide in the opposite direction. The rear end of the buckle then engages in the corresponding slot, enabling quick assembly and disassembly of the tillage blade. The tillage blade can be removed by repeatedly pressing the pressing frame, saving time and effort and improving the machine's working efficiency.

[0014] 2. In this utility model, when the drive motor is started, its output end drives the worm to rotate. The worm meshes with the top worm wheel, causing the worm wheel to drive the middle support shaft to rotate inside the front end of the machine body. The double gear in the middle of the outer wall of the support shaft rotates accordingly, and then the double gear drives the double rack on the front side to move. The double rack slides along the outer wall of the two limiting frames inside the limiting groove. The limitation of the two limiting frames ensures that the double rack can only move vertically, ensuring the stability of the double rack's movement. Since the double rack is connected to the weeder through the connecting column, the height of the weeder can be adjusted by adjusting the lifting height of the double rack to adapt to different weeding needs of cultivated land.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model is provided: a multi-functional agricultural machinery tiller, including a body 1 and a weeder 9. A fixing mechanism 2 is installed at the bottom middle of the body 1. The fixing mechanism 2 is used for quick disassembly and assembly of the blade head. An adjustment mechanism 3 is installed at the front end of the body 1. The adjustment mechanism 3 is used to adjust the height of the weeder 9 as needed. The fixing mechanism 2 includes a rotating shaft 201, which is installed at the bottom center of the machine body 1. Mounting shafts 203 are installed at both the left and right ends of the rotating shaft 201. The inner walls of the left and right ends of the rotating shaft 201 are slidably connected to the adjacent ends of the outer walls of the mounting shafts 203. Multiple slots 202 are provided at the adjacent ends of the outer walls of the mounting shafts 203. Multiple tillage blades 204 are fixedly connected to the outer walls of the mounting shafts 203. Multiple drive components 205 are installed inside both the left and right ends of the rotating shaft 201. Multiple drive components 205 each include a pressing frame 2051, which is installed inside the left and right ends of the rotating shaft 201 respectively. Multiple steel ropes 2052 are fixedly connected to the rear side of the outer wall of the right front pressing frame 2051. Support columns 2053 are installed on the outer wall of the steel ropes 2052. The outer wall of the support column 2053 is fixedly connected to the inside of the rotating shaft 201. The outer wall of the steel ropes 2052 is slidably connected to the outer wall of the support column 2053. Alloy buckles 2055 are fixedly connected to the rear side of the outer wall of the steel ropes 2052. The front end of the alloy buckle 2055 is slidably connected to the inside of the rotating shaft 201. The rear end of the outer wall of the alloy buckle 2055 is slidably connected to the inside of the slot 202. Multiple high-carbon springs 2054 are fixedly connected to the front side of the outer wall of the alloy buckle 2055. The front side of the outer wall of the multiple high-carbon springs 2054 is fixedly connected to the inner wall of the rotating shaft 201. Specifically, pressing the pressing frame 2051, taking the right front pressing frame 2051 as an example, can drive the steel rope 2052 connected to the rear to move, causing the steel rope 2052 to slide along the outer wall of the support column 2053 fixed inside the rotating shaft 201. This, in turn, causes the steel rope 2052 to pull the alloy buckle 2055 on the rear side to slide inside the rotating shaft 201. At this time, the alloy buckle 2055 will squeeze the high carbon spring 2054 on the front side, causing it to continuously accumulate elastic potential energy, thus securing the device. After the mounting shaft 203 slides along the inner wall of the left and right ends of the rotating shaft 201 to align the slot 202 with the alloy buckle 2055, the pressing frame 2051 is released, and the high carbon spring 2054 returns to its original position, pushing the alloy buckle 2055 to slide in the opposite direction. The rear end of the alloy buckle 2055 is then inserted into the corresponding slot 202, enabling quick assembly and disassembly of the tillage blade 204. The tillage blade 204 can be removed by repeatedly pressing the pressing frame 2051, which is very time-saving and labor-saving, and improves the working efficiency of the machine.

[0019] Reference Figure 1 , Figure 2 and Figure 7 The adjustment mechanism 3 includes multiple connecting columns 301, all of which are installed at the front end of the body 1. The front side of the outer wall of the connecting column 301 is fixedly connected to the rear side of the outer wall of the weeder 9. A double rack 302 is fixedly connected to the rear side of the outer wall of the connecting column 301. A limiting groove 303 is opened in the middle of the double rack 302. A power component 304 is installed at the top of the double rack 302. A stabilizing component 305 is installed inside the limiting groove 303. The power assembly 304 includes a drive motor 3041, model 130ST-M15015. Its internal driver receives external commands (such as position pulses and speed signals) and simultaneously acquires the actual rotor state through an encoder. If there is a deviation between the actual state and the command, the driver adjusts the stator current, changing the rotational magnetic field speed or direction until the deviation is eliminated, achieving high-precision control. The drive motor 3041 is mounted on the top of the double rack 302. The output of the drive motor 3041... A worm gear 3042 is fixedly connected to the end. A worm wheel 3043 is installed on the top of the outer wall of the worm gear 3042. The top of the outer wall of the worm gear 3042 meshes with the bottom of the outer wall of the worm wheel 3043. A support shaft 3045 is fixedly connected to the middle of the worm wheel 3043. The left and right sides of the outer wall of the support shaft 3045 are rotatably connected to the front end of the machine body 1. A double gear 3044 is fixedly connected to the middle of the outer wall of the support shaft 3045. The front side of the outer wall of the double gear 3044 meshes with the rear side of the outer wall of the double rack 302. The stabilizing component 305 includes multiple limiting frames 3051, all of which are installed inside the limiting groove 303. The middle part of the outer wall of the limiting frame 3051 is slidably connected to the inside of the limiting groove 303. A support frame 3053 is installed on the outer wall of the drive motor 3041. The inside of the support frame 3053 is fixedly connected to the outer wall of the drive motor 3041. The left and right sides of the outer wall of the support frame 3053 are fixedly connected to the inside of the front end of the machine body 1. A protective cover 3052 is fixedly connected to the front end of the outer wall of the machine body 1. The left and right sides of the outer wall of the limiting frame 3051 are fixedly connected to the inner wall of the protective cover 3052. The front side of the outer wall of the limiting frame 3051 is fixedly connected to the front side of the inner wall of the protective cover 3052. Specifically, starting the drive motor 3041 causes the output end to drive the worm 3042 to rotate. Through the meshing of the worm 3042 and the worm wheel 3043 at the top, the worm wheel 3043 drives the support shaft 3045 in the middle to rotate inside the front end of the machine body 1. This causes the double gear 3044 in the middle of the outer wall of the support shaft 3045 to rotate accordingly. In turn, the double gear 3044 drives the double rack 302 on the front side to move. The double rack 302 slides along the outer wall of the two limiting frames 3051 inside the limiting groove 303. The limitation of the two limiting frames 3051 allows the double rack 302 to move only a single point vertically, thus ensuring the stability of the double rack 302. Since the double rack 302 is connected to the weeder 9 through the connecting column 301, the height of the weeder 9 can be adjusted by adjusting the lifting height of the double rack 302 to adapt to different weeding needs of cultivated land.

[0020] Reference Figure 1 , Figure 2 and Figure 3A welding frame 4 is installed at the bottom of the body 1. Wheels 5 are installed on the left and right sides of the bottom of the welding frame 4. A handrail 6 is installed at the rear of the body 1. Handles 7 are fixedly connected to the left and right sides of the rear of the handrail 6. A connecting frame 8 is installed in the middle of the handrail 6. The connecting frame 8 adopts an arched design. Specifically, a welding frame 4 is installed at the bottom of the machine body 1, and wheels 5 are installed on both the left and right sides of the bottom. This reduces the friction between the machine body 1 and the ground when moving, allowing the machine body 1 to flexibly adjust its position to adapt to different work site requirements. A handrail 6 is provided at the rear of the machine body 1. The tiller can be moved by the handle 7, which improves the comfort and stability of the grip and prevents the hand from slipping during the pushing process. A connecting frame 8 is welded in the middle of the handrail 6, which can enhance the structural strength of the handrail 6 and prevent the handrail 6 from deforming or breaking during use. The connecting frame 8 adopts an arched design to adapt to the central structural shape of the handrail 6, further optimizing the force distribution of the handrail 6 and ensuring that the handrail 6 can be used stably for a long time.

[0021] Working principle: Pressing the pressing frame 2051, taking the right front pressing frame 2051 as an example, can drive the steel rope 2052 connected to the rear to move, causing the steel rope 2052 to slide along the outer wall of the support column 2053 fixed inside the rotating shaft 201. In turn, the steel rope 2052 pulls the alloy buckle 2055 on the rear side to slide inside the rotating shaft 201. At this time, the alloy buckle 2055 will squeeze the high carbon spring 2054 on the front side, causing it to continuously accumulate elastic potential energy, and pushing the mounting shaft 203 along the rotating shaft 201. After the inner walls of the left and right ends slide to align the slot 202 with the alloy buckle 2055, release the pressing frame 2051. The high carbon spring 2054 returns to its original position and pushes the alloy buckle 2055 to slide in the opposite direction. The rear end of the alloy buckle 2055 is inserted into the corresponding slot 202. Through the cooperation of multiple alloy buckles 2055 and slots 202, the tillage blade 204 can be quickly disassembled and assembled. The tillage blade 204 can be removed by repeatedly pressing the pressing frame 2051, which is very time-saving and labor-saving and improves the working efficiency of the machine. When the drive motor 3041 is started, its output end can drive the worm 3042 to rotate. Through the meshing action between the worm 3042 and the worm wheel 3043 at the top, the worm wheel 3043 drives the support shaft 3045 in the middle to rotate inside the front end of the machine body 1. This causes the double gear 3044 in the middle of the outer wall of the support shaft 3045 to rotate accordingly. In turn, the double gear 3044 drives the double rack 302 on the front side to move. The double rack 302 slides along the outer wall of the two limiting frames 3051 inside the limiting groove 303. The limitation of the two limiting frames 3051 can restrict the double rack 302 to only a point of vertical movement, thereby ensuring the stability of the double rack 302. Since the double rack 302 is connected to the weeder 9 through the connecting column 301, the height of the weeder 9 can be adjusted by adjusting the lifting height of the double rack 302 to adapt to different weeding needs of cultivated land.
