Description

Technical Field

[0001] This utility model relates to the field of garden management machines, and in particular to an energy-saving transmission garden management machine. Background Technology

[0002] Traditional garden tillers are mostly powered by internal combustion engines, which are energy-intensive and emit large amounts of exhaust gases, such as harmful components like HC and CO. If used in greenhouses, these gases can cause air pollution, negatively impact crop growth, and may even lead to operator poisoning. Meanwhile, with global energy resources becoming increasingly scarce and countries advocating for green and low-carbon development, including my country's "dual-carbon" goals, developing energy-efficient garden tillers can reduce energy consumption and carbon emissions in agricultural production, aligning with sustainable development requirements.

[0003] Difficult to cope with complex field conditions: There may be obstacles such as ditches, slopes, and protruding rocks in the field. Fixed-height casters may cause the bottom of the equipment to easily collide with the ground or even get stuck, making it impossible to pass normally. In severe cases, the equipment may drag soil or crops, damaging farmland. Utility Model Content

[0018] Reference Figures 1-4This utility model provides an embodiment of an energy-saving transmission garden tiller, comprising a body 1. An oil tank 9 is welded to the top of the body 1, storing fuel to provide energy for operation. A connecting cover 2 is bolted to the bottom of the body 1, protecting the internal transmission components. Fixing plates 3 are welded to the outer walls of both ends of the connecting cover 2. Threaded holes are formed inside the fixing plates 3, through which bolts 4 pass and are threadedly connected. A movable plate 5 is rotatably connected to the bottom of the bolts 4 via bearings. A caster wheel 6 is bolted to the bottom of the movable plate 5. When the bolts 4 are rotated, the movable plate 5 moves vertically under the action of the threads, thereby adjusting the height of the caster wheel 6. A handle 8 is welded to the outer wall of the right side of the body 1. The handle 8 is covered with a non-slip rubber sleeve for easy gripping and operation by the operator. The outer wall of the rear end of the oil tank 9 is fixedly connected to the drive pulley 11 by a key. The middle of the connecting cover 2 is rotatably connected to the rotating column 7 by a bearing. The outer wall of the rear end of the rotating column 7 is fixedly connected to the driven pulley 13 by a key. The outer wall of the rotating column 7 is fixedly connected to the rotating wheel 14 by welding. The inner left side of the connecting cover 2 is rotatably connected to the rotating column 15 by a bearing. The outer left side of the machine body 1 is fixedly connected to the fixed plate 10 by welding.

[0019] A buffer plate 17, made of elastic steel, is provided on the left side of the fixed plate 10. Slide rods 18, cylindrical in shape, are welded and fixedly connected to the upper and lower ends of the fixed plate 10. A pressing block 20, made of alloy steel, is welded and fixedly connected to the outer right wall of the buffer plate 17. One end of the pressing block 20 is rotatably connected to a diagonal rod 21, made of alloy steel, via a pin. A belt 12, made of rubber and with teeth on its inner side, is positioned between the driving pulley 11 and the driven pulley 13 to ensure stable power transmission. A cleaning blade 16, made of high-strength alloy, is welded and fixedly connected to the outer wall of the rotating column 15. The cleaning blade 16 meshes with the teeth of the rotating wheel 14, allowing the rotating wheel 14 to rotate synchronously. One end of the diagonal rod 21 is rotatably connected to a sliding block 22 via a pin. The sliding block 22 has a through hole that matches the sliding rod 18. The sliding block 22 is fitted onto the outer wall of the sliding rod 18 and can slide along the axis of the sliding rod 18. Damping springs 23 are fitted at both ends of the sliding rod 18. One end of the damping spring 23 is fixedly connected to the sliding block 22 by welding. The damping spring 23 is made of high-strength spring steel and has good elastic recovery performance. A limiting block 24 is provided at the other end of the damping spring 23. The limiting block 24 is a circular block structure and is fixedly connected to the outer wall of the sliding rod 18 by welding. The limiting block 24 can limit the sliding range of the sliding block 22 and prevent it from detaching from the sliding rod 18. The slide bar 18 is equipped with a damper 19. The two ends of the slide bar 18 on the left side are fixedly connected to the damper 19 by bolts. The other end of the damper 19 is fixedly connected to the buffer plate 17 by bolts. The damper 19 is a hydraulic damper, which can provide damping force to slow down the movement speed of the buffer plate 17.

[0020] Working Principle: The oil tank 9 at the top of the machine body 1 provides power to the equipment. The drive pulley 11 on the outer wall of its front end rotates with the power system, transmitting power through the middle belt 12 to the driven pulley 13 at the rear end of the rotating column 7 in the middle of the connecting cover 2, thereby driving the rotating column 7 to rotate. The rotating wheel 14 on the outer wall of the rotating column 7 rotates accordingly. Since the rotating wheel 14 is engaged with the cleaning blade 16 on the outer wall of the rotating column 15, the rotating wheel 14 drives the rotating column 15 and the cleaning blade 16 to rotate, thus completing tasks such as clearing weeds and loosening soil. In terms of movement and adjustment, bolts 4 are rotatably connected inside the fixing plates 3 at the front and rear ends of the connecting cover 2 at the bottom of the machine body 1. Rotating the bolts 4 can drive the bottom moving plate 5 to move up and down, thereby adjusting the height of the universal wheels 6 at the bottom of the moving plate 5 to adapt to different terrains. The universal wheels 6, together with the handle 8 on the right side, enable the equipment to move... The device moves flexibly and turns in the field. When the buffer plate 17 is impacted, the squeezing block 20 on its right side will push the inclined rod 21, causing the sliding block 22 at the other end of the inclined rod 21 to slide along the slide rod 18. The sliding block 22 squeezes the damping springs 23 at both ends of the slide rod 18. At the same time, the damper 19 on the left side of the slide rod 18 also generates damping force. Through spring deformation and damping, the impact energy is absorbed, protecting the body 1 and the fixed plate 10 from damage. The limiting block 24 at the other end of the damping spring 23 can limit the sliding block 22.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
