Double-motor and double-adjustable mechanical limiting ventilator

Abstract

The invention discloses a double-motor double-adjustable mechanical limiting exhaust fan which comprises an outer shell, two limiting adjusting mechanisms, a controller and an adjusting panel, the controller is fixedly connected in the outer shell, the two limiting adjusting mechanisms are symmetrically arranged in the outer shell, and the adjusting panel is fixedly connected in the outer shell. The adjusting panel is fixedly connected to the side wall of the outer shell. The invention belongs to the technical field of greenhouse air blowers, and particularly provides a double-motor double-adjustable mechanical limiting air blower which is provided with double motors, internally provided with adjustable limiting devices, capable of achieving self-induction adjusting control, accurate in adjustment and control, large in output distance, long in service life, convenient to install, high in practicability, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of greenhouse ventilators, in particular to a double-motor double-adjustable mechanical limit ventilator. Background technique [0002] Air vents are set on the roof of the greenhouse. By regularly opening and closing the vents, the greenhouse is ventilated and ventilated, so as to effectively adjust the temperature and humidity in the greenhouse. In the cold winter, we need to allow the shed to accumulate more temperature. When the night temperature is high, the shed needs to achieve the ideal ventilation effect, so it is necessary to open the wind to a certain temperature, and there are certain requirements for the size of the tuyere. [0003] The blower in the prior art is simple in design, single in function, inaccurate in controlling the size of the tuyere, poor in time control of the size of the tuyere, unsatisfactory temperature accumulation effect and ventilation effect in the shed, and increases the...

AI Technical Summary

Problems solved by technology

[0003] The exhaust fan in the prior art has simple design, single function, inaccurate control of the size of the tuyere, and poor time control of the size of the tuyere, resulting in unsatisfactory accumulated temperature and ventilation effects in the greenhouse, and increases the workload of the staff at the same time; Moreover, the blower on the market is generally a single motor with a through-shaft output, and the limit installation is external, the output distance is short, the limit structure is easily damaged, and the service life of the blower is greatly reduced.
