Open type dry hot air generating device

Abstract

The invention belongs to the technical field of dry hot air simulation, and discloses an open type dry hot air generating device. The open type dry hot air generating device comprises a base, wherein four bottom feet are installed at the bottom of the base, every two of the four bottom feet form a group and are symmetrical in pairs, fixing frames are installed on the side, close to the positions among the four bottom feet, of the bottom of the base, every two of the six fixing frames form a group, and every two fixing frames are symmetrical in pairs; air injection plates are installed in the six fixing frames correspondingly, and adjusting bolts are connected between the six fixing frames and the air injection plates correspondingly in a screwed mode. According to the open type dry hot air generating device, by pulling the air injection plates, the air injection plates move on the fixing frames, so that the positions of the air injection plates and air injection heads are adjusted; by screwing the adjusting bolts, the positions of the air injection plates and the air injection heads are fixed; surrounding hot air is isolated through a baffle plate, so that the open type dry hot air generating device is convenient to carry out a comparison test, the comparison test can be carried out according to the requirements of a user, and the test efficiency of the device in use is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of dry hot air simulation, and in particular relates to an open dry hot air generating device. Background technique [0002] Dry hot wind, also known as "dry wind", "hot dry wind", commonly known as "fire south wind" or "fire wind", is a kind of agricultural disaster weather with high temperature, low humidity and certain wind force. First, it is a kind of dry and hot wind that occurs in the warm season and causes damage to the wheat grains during the milk maturity stage. When the dry and hot wind is hot, the temperature rises significantly and the humidity drops significantly, accompanied by a certain wind force, the transpiration is intensified, and the root system cannot absorb water. It often leads to insufficient grain filling of wheat, severe grains and even withering and death. It occurs in the late spring and early summer in North China, Northwest my country and Huanghuai region in China. It is general...
