A kind of ventilation pipe for sweet potato cellar

Abstract

The invention discloses a ventilation pipe for a sweet potato cellar, the structure of which comprises a blocking cylinder, a muffler cylinder, a connecting pipe, and an air outlet. The top of the tuyere is embedded and connected, and the end of the connecting pipe on the other side is welded to the blocking tube. The blocking tube includes a partition turntable, an air inlet and outlet, a circulation tube, and a fixing seat. The inner end is embedded and connected, and the invention rotates with the help of the wind guide through the partition turntable, so that the internal pest control sheet rotating roller is triggered to cooperate with the outwardly protruding baffle to form a gap to provide activity space for the pests, so that when the net is shot Under the rotation of the board, the surface of the screen continuously slaps the crawling pests, so that the pests change the direction of entry, effectively preventing the ventilation pipe from becoming a guide pipe for pests, and solving the problem of the internal sweet potato being eaten by the pests that crawled into it. .

Description

technical field [0001] The invention relates to the technical field of sweet potato storage, in particular to a ventilation pipe for sweet potato cellars. Background technique [0002] In order to store the harvested sweet potatoes reasonably and ensure that the sweet potatoes are not prone to rot during storage, most places still use the traditional sweet potato cellar to store the harvested sweet potatoes. It is necessary to rely on ventilation pipes to achieve ventilation and oxygen supply in the kiln; [0003] But there are the following deficiencies in the prior art: the current ventilation pipe for sweet potato cellar, because the sweet potato kiln is all set on the side wall of the mountain, and the pipe mouth is aligned with the external air outlet, so that the pests in the mountain forest easily climb into the sweet potato from the pipe mouth When the sweet potatoes are eaten in the kiln, the sweet potatoes rot, which causes the ventilation pipe to become the guide...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a ventilation pipe for sweet potato cellars to solve the problem of the current ventilation pipe for sweet potato cellars in the prior art. Since the sweet potato kilns are all set up on the side walls of the mountain body, the nozzles are aligned with each other. The external air outlet makes it easy for pests in the forest to climb into the sweet potato kiln from the mouth of the pipe to eat sweet potatoes, and the sweet potatoes rot, which makes the ventilation pipe a guide pipe for pests, which in turn makes the stored sweet potatoes vulnerable to pests. food problem
