Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically a safety assist device for micro-tillers. Background Technology

[0002] Mini tillers are widely used in agricultural production due to their compact size, flexibility, and ease of operation, especially in mountainous and hilly areas and small plots of farmland, where they play an important role. Mini tiller safety assist devices are equipment installed on mini tillers to enhance the safety of mini tiller operation, protect the safety of operators, and improve work efficiency.

[0003] Traditional safety devices mostly use protective covers to protect the parts on the mini tiller. This not only hinders the heat dissipation of the engine and transmission components, but also obstructs some parts after installation, making it difficult for the operator to directly observe the condition of the internal parts. When maintaining or repairing the mini tiller, the protective cover must be removed before the parts can be operated, which consumes a lot of time and effort.

[0004] Therefore, this utility model provides a safety assist device for micro-tillers. Utility Model Content

After installation, the sliding assembly is lowered, and the mini-tiller can be started for operation. Through the above structure, the design of fixing multiple protective rods 13 to the middle of the support rods 1 using the limiting plate 14 and bolt 15 not only makes it easy for the operator to remove and replace the damaged protective rod 13, but also makes the device form a stable frame, effectively preventing the protective rod 13 from falling off due to vibration or external force during the operation of the mini-tiller, thus enhancing the strength and stability of the device.

[0025] like Figures 1 to 3 As shown, the sliding assembly includes a fixed block 2; the bottom of the support rod 1 is rotatably connected to the fixed block 2; the middle of the fixed block 2 has multiple equally spaced limiting holes 22; the middle of the fixed block 2 is detachably connected to a connecting block 23; the middle of the connecting block 23 near the middle of the limiting holes 22 is slidably connected to two symmetrically arranged limiting blocks 26; the middle of the limiting blocks 26 is fixedly connected to a first spring 27; the bottom of the limiting blocks 26 is fixedly connected to two symmetrically arranged fixing plates 24; the middle of the limiting holes 22 is rotatably connected to a guide plate 25; the middle of the fixing plates 24 is rotatably connected to...

After using the device, it is removed, and the protective rod 13 is placed in the second placement slot 33. The rod 13 and the first placement slot 32 can be used to place the limiting plate 14 and bolt 15 to prevent the device from being damaged or lost due to careless placement. The buckle 18 is connected to the connecting parts on the mini tiller. When the mini tiller is working, the second spring 4 and the shock-absorbing pad 41 can absorb and buffer the vibration caused by uneven ground to avoid damage to the device. The light emitted by the warning light 51 can make the mini tiller more noticeable to people around when it is working, especially in low light environments. When the pulley 21 rotates, the end of the scraper 6 will contact the pulley 21 and scrape off the mud attached to the surface of the pulley 21. This material is not only light but also has a certain degree of toughness, which can play a buffering role when encountering collisions.
