Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to an agricultural machinery and equipment for weeding. Background Technology

[0002] Weeds are plants that grow in areas that are harmful to human survival and activities. They are generally non-cultivated wild plants or plants that are harmful to humans. Weeds are characterized by multiple ways of spreading, strong reproductive and regeneration capabilities, generally shorter life cycles than crops, mature seeds falling as soon as they ripen, strong resistance to adverse conditions, and high photosynthetic efficiency. Some weed seeds or pollen contain toxins. Therefore, we use agricultural machinery for weeding when clearing weeds.

[0003] Agricultural machinery used for weeding is called a weeding machine. Its core function is to efficiently remove weeds in farmland, orchards, lawns, and other fields by mechanical means, reducing competition between weeds and crops for nutrients, water, and sunlight. At the same time, it reduces the labor intensity of manual weeding and improves agricultural production efficiency. It achieves weeding by precisely transmitting power to the actuator and performing specific mechanical actions. Modern weeding machines are generally equipped with strict safety protection structures, which reduces safety risks but also limits operational flexibility. The traditional one-piece protective cover has been split into a three-section structure, with each section connected to the machine body by a damping shaft. However, the improved machine still has the problem of time-consuming blade disassembly. Utility Model Content

[0036] Specifically, rotating the rocker arm 301 drives the worm gear 304 to rotate, which in turn drives the worm wheel 309 to rotate. The rotation of the worm wheel 309 causes the threaded rod 305 on its inner wall to rotate upward. Since the threaded groove 306 is fixed on the base plate 308, when the threaded rod 305 rotates upward, it will push the bearing 307 to move upward, thereby enabling the mechanism to lift and lower. The oil tank 5 is used to store fuel, the cover 4 is responsible for sealing, the handle 10 is convenient for gripping and operation, and the protective cover 11 provides safety protection.

[0039] Working principle: First, press the rotating rod 201 upwards. The rotating rod 201 moves the baffle 202. The baffle 202 presses the spring 203 upwards. The rotating rod 201 moves the rotating rod 205 upwards and enters the opening block 206. Then, rotate the rotating rod 201 to make the rotating rod 205 engage with the opening block 206 for fixation. Then, press the rotating rod 201 again and rotate the rotating rod 201 to make the rotating rod 205 separate from the opening block 206, thereby achieving quick disassembly.

[0040] Rotating the rocker arm 301 causes the worm gear 304 to rotate, which in turn drives the worm wheel 309 to rotate. The rotation of the worm wheel 309 causes the threaded rod 305 on its inner wall to rotate upward. Since the threaded groove 306 is fixed on the base plate 308, when the threaded rod 305 rotates upward, the bearing 307 will move upward, causing the mechanism to lift and lower.
