Description

Technical Field

[0001] This utility model relates to the field of greenhouse curtain limiting technology, and in particular to a curtain limiting device for greenhouse mantis arms. Background Technology

[0002] Greenhouse curtain rolling machines, or simply curtain rolling machines, are agricultural machinery specifically designed for the automatic rolling up and down of straw curtains in greenhouses. This equipment greatly improves the efficiency of greenhouse management and promotes the development of agricultural mechanization. Depending on the installation location, greenhouse curtain rolling machines can be divided into front-mounted and rear-mounted types. Furthermore, based on the power source, they can be divided into electric and manual types. Electric curtain rolling machines are widely used due to their convenience and efficiency, typically employing 220V or 380V AC power. The core component of the curtain rolling machine is the main unit, which is essentially a reducer. A common design is a five-axis all-steel shell structure. This design not only improves the product's lifespan but also enhances safety, effectively protecting the personal safety and economic interests of farmers. When using greenhouse curtain rolling machines, a curtain-rolling limit device similar to a greenhouse mantis arm is employed.

[0003] However, in practical applications, it is necessary to perform limit operation. If the limit operation cannot be performed, it will affect the ease of use of the device, affect the operation of subsequent staff, and reduce the efficiency of the device. Utility Model Content
