Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, and specifically relates to an agricultural machine with a replaceable mechanical head. Background Technology

[0002] There are many types of agricultural machinery on the market, such as rotary tillers, weeders, ditchers, and mowers. In order to improve planting efficiency, farmers need to purchase a variety of agricultural machinery to deal with problems in field management, which leads to increasingly higher planting costs.

[0003] Especially since the lawnmowers currently on the market are specialized lawnmowers, these specialized lawnmowers only need to be used two to three times a year during the fruit-bearing period to limit weed growth, prevent weeds from growing too tall and competing with fruit trees for nutrients, and avoid nutrient loss from the soil after weeding and uprooting, which is detrimental to fruit growth. If farmers were to purchase a specialized lawnmower separately for mowing, it would be uneconomical for them. In addition, specialized lawnmowers use the engine's output shaft to drive both mowing and movement, which can easily lead to breakage of the engine's output shaft. Therefore, manufacturers can provide farmers with agricultural machinery that covers multiple functions, making one machine multi-functional. This can solve different problems for farmers in their fields and orchards, greatly reduce farmers' purchase costs, or make it convenient for farmers to use it with other equipment that requires power.

[0004] To address this issue, our company has developed an agricultural machine with a replaceable mechanical head. Utility Model Content
