Ventilation pipe for sweet potato cellar

Abstract

The invention discloses a ventilation pipe for a sweet potato cellar, which structurally comprises a pest prevention barrel, a silencing barrel, a connecting pipe and an air outlet, the two ends of the pest prevention barrel are connected with the top end of the connecting pipe in a welded mode, the top end of the connecting pipe is connected with the two ends of the silencing barrel through flanges, the front end of the silencing barrel is in overall clearance fit with the pest prevention barrel, the tail end of the connecting pipe is connected with the top end of the air outlet in an embedded mode, the pest prevention barrel comprises a partition rotating disc, an air inlet and outlet, a circulation barrel and a fixing base, the whole partition rotating disc is movably matched with the interior of the circulation barrel, and the two ends of the circulation barrel are fixedly connected with the inner ends of the air inlet and outlet in an embedded mode. The partition rotating disc is assisted by wind guide to rotate, therefore, under the triggering of a pest removal sheet rotating roller, a gap is formed in cooperation with an outwards-protruding baffle to provide an activity space for pests, the surface of a net plate continuously slaps the crawl pests crawling in the ventilation pipe under the rotation of a net plate, the entering direction of the pests is changed, the situation that the ventilation pipe becomes a pest guide pipe is effectively avoided, and the problem that sweet potatoes inside are gnawed by the pests crawling in the ventilation pipe is solved.

Description

technical field [0001] The invention relates to the technical field of sweet potato storage, in particular to a ventilation pipe for a sweet potato cellar. Background technique [0002] In order to store the harvested sweet potatoes reasonably and ensure that the sweet potatoes are not easy to rot during storage, most places still use the traditional sweet potato cellar to store the harvested sweet potatoes, but the problem of insufficient ventilation in the sweet potato cellar always exists. It is necessary to rely on ventilation pipes to realize the ventilation and oxygen supply to the kiln; [0003] But there are following deficiencies in the prior art: the current ventilation pipe for sweet potato cellar, because the sweet potato kiln is all opened on the side wall of the mountain body, the mouth of the pipe is aligned with the external air outlet, so that the pests in the mountain forest can easily climb into the sweet potato from the mouth of the pipe. The sweet potat...

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
