【考案の詳細な説明】
産業上の利用分野
本考案は穀粒を乾燥するに当り発生する騒音を防止する
装置に関する改良である。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is an improvement on a device for preventing noise generated when drying grains.
従来の技術および考案が解決しようとする問題点従来の
穀粒乾燥機においては乾燥室を通過した湿気を含む廃熱
風を機体の背面に取付けた吸引ファンにより機外へ吸引
排出するが、この際吸引ファンより著しく騒音が発生し
、終夜運転することの多い乾燥作業においては寝しずま
った夜間では特に著しい公害問題をひき起こす。Problems to be solved by conventional techniques and ideas In conventional grain dryers, the waste hot air containing moisture that has passed through the drying chamber is sucked out of the machine by a suction fan attached to the back of the machine. Suction fans generate significant noise, and in drying operations that often run all night, it causes a significant pollution problem, especially at night when people are asleep.
本考案は、この吸引ファンの騒音は吸引ファンを内蔵す
る外胴が振動することにより発生するとの知見に基き、
この騒音の発生を阻止することを目的とする。This invention is based on the knowledge that the noise of this suction fan is generated by the vibration of the outer body that houses the suction fan.
The purpose is to prevent this noise from occurring.

間に空間Ｍを形成する。Means for Solving the Problems To make the present invention easier to understand, the present invention will be explained using the reference numerals of the embodiments shown in the drawings.The outer shell 1 has a suction fan F built therein and communicates with a narrow suction side and a wide discharge side. The suction side of is attached to body A, a hose H formed into a cylindrical shape is surrounded around the outer periphery of nuclear external use 1, and its base is attached to body A to form a space M between hose H and outer body 1. do.
作用
吸引ファンＦにより狭い吸引側より湿気を含め廃熱風を
吸引し広い排出側より排出側に連結するホースＨにより
機外に廃熱風を排出する。The suction fan F sucks in waste hot air including moisture from the narrow suction side, and the waste hot air is discharged from the wide discharge side to the outside of the machine through the hose H connected to the discharge side.
そして吸引ファンＦを内蔵する外胴１が振動することに
より発生する振動音は密閉された空間Ｍに阻止されてホ
ースＨの外に洩れ出ない。The vibration noise generated by the vibration of the outer shell 1 housing the suction fan F is blocked by the sealed space M and does not leak out of the hose H.
実施例
図面に示す吸引ファンＦは回転羽根２と固定羽根３より
成る。The suction fan F shown in the drawings is composed of rotating blades 2 and fixed blades 3.

を形成する。The hose H is formed by pasting a synthetic resin membrane 5 such as vinyl on a spiral frame 4 made of pure gold, and this is fitted to the outside of the outer body 1, and the base of the hose H has a bellows-like wrinkle. While forming the outer shell 1
It is attached to the fuselage A together with one end, and there is a space M between it and the outer body 1.
form.
６は機体の背面に突設する円環で、その外周にホースＨ
の基部を嵌め、その外側より止環７により締着する。6 is a ring that protrudes from the back of the aircraft, and a hose H is attached to the outer circumference of the ring.
, and tighten it from the outside with the retaining ring 7.

いので排気能力が増大し、外胴１内に停滞することなく
よく排出する、という効果を生ずる。Effects of the invention In the present invention, a cylindrical hose H is surrounded on the outer periphery of the outer shell 1 that includes the suction fan F, which is the source of noise, over the narrow suction side and the wide discharge side, and the outer shell 1 and the hose H are Since a space M is formed between the outer shell 1 and the hose H, the space M is sealed between the outer shell 1 and the hose H. Therefore, the vibration noise of the outer shell 1 due to the rotation of the suction fan F is transmitted to the hose H through the sealed space M. It will not be absorbed or reflected and leak to the outside, and since the space M can be filled with sound absorbing material, vibration sound can be further absorbed.
Since the suction side of the rising stroke 1 is narrow, the waste hot air inside the fuselage A is quickly absorbed by the fan F, and the exhaust side of the outer shell 1 is wide, so the exhaust capacity increases and it does not stagnate inside the outer shell 1. It has the effect of being well discharged.
