Double motor and double adjustable mechanical limiting air blower

Abstract

The invention discloses a double motor double adjustable mechanical limiting air blower. The fan comprises: an outer shell, limiting adjusting mechanisms, a controller, and an adjusting panel. The controller is fixedly connected in the outer shell; two limiting adjusting mechanisms are symmetrically arranged 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 ventilation fans for greenhouses, and specifically refers to a double-motor double-adjustable mechanical limit ventilation fan. Background technique [0002] The air outlet is set on the roof of the greenhouse, and the greenhouse is ventilated by regularly opening and closing the air outlet, so as to effectively adjust the temperature and humidity in the shed. In the cold winter, we need to let the shed accumulate more temperature. When the night temperature is high, the shed needs to achieve the ideal ventilation effect, so it needs to be turned on at a certain temperature, and there are certain requirements for the size of the air outlet. [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, a...

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.
