【産業上の利用分野】[Industrial applications]

本考案は、播種ドラムに連通した吸引式ブロワより発生する騒音を低減させる ことができる播種機のブロワ防音装置に関する。 The present invention relates to a blower soundproofing device for a seeding machine, which can reduce noise generated by a suction blower communicating with a seeding drum.

【0002】[0002]

【従来の技術】[Prior art]

従来は、種子を吸引する多数の吸引孔を有した回転式の播種ドラムを機体下方 の吸引式ブロワに連通連設して構成する播種機において、本出願人が既に出願し た実願平5−40570号に見られるように、吸引式ブロワの排気側に設けられ た短い排気口管がストレートに外方に開放されていた。 Conventionally, in a sowing machine constituted by connecting a rotary seeding drum having a large number of suction holes for sucking seeds to a suction blower at the lower part of the machine, the application was already filed by the applicant. As seen in No.-40570, a short exhaust port pipe provided on the exhaust side of the suction blower was straight and opened to the outside.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、吸引式ブロワから排気口管を通して直ちに排気されることにな ってしまうので、吸引式ブワロより発生する大きな音がそのまま外方周囲に抜け て騒音となったり、排風が機体の周囲に強く吹き出されながら埃をたてたり作業 者に吹きつけたりして、作業環境が悪い、といった不具合を呈している。 However, since it will be immediately exhausted from the suction blower through the exhaust pipe, the loud noise generated by the suction blower will be emitted to the outside as it is and noise will be emitted, and the exhaust air will be emitted around the aircraft. While being strongly blown off, it creates dust and blows it on the worker, resulting in a bad working environment.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、そのような不具合を解決し、簡単な構造にして好適に実施できるよ う工夫したものであり、そのため、種子を吸引する多数の吸引孔を有した回転式 の播種ドラムを機体下方の吸引式ブロワに連通連設して構成する播種機において 、前記吸引式ブロワを内装したブロワケースの排気側には排気口管を挿着し、該 排気口管の外端部には内面に凹凸を有して横方向に屈曲させた軟質樹脂材のホー スの一端部を嵌合して連通連設し、該ホースの外周には吸音材を接着して構成し たものである。 The present invention has been devised so as to solve such a problem and to be preferably implemented with a simple structure. Therefore, a rotary sowing drum having a large number of suction holes for sucking seeds is provided on the lower side of the machine body. In the seeding machine configured to communicate with the suction type blower, the exhaust side pipe is attached to the exhaust side of the blower case containing the suction type blower, and the inner surface is attached to the outer end of the exhaust side pipe. One end of a soft resin material hose, which has unevenness and is bent in the lateral direction, is fitted and connected continuously, and a sound absorbing material is bonded to the outer periphery of the hose.

【0005】[0005]

【作用】[Action]

従って、吸引式ブロワからの排気が排気口管からホース内に流されると、屈曲 した該ホースに案内されて横方向に向きを変えるとともに凹凸にあたりながら勢 いが弱まって周囲に悪影響を与えないように流出することになり、その排気とと もにホース内に伝わってくるブロワからの大きい音は、ホース内面の凹凸に反響 しながら、吸音材を接着した軟質樹脂材の屈曲したホースに充分に吸音されるこ とになって、低音となるように低減されることになる。 Therefore, when the exhaust air from the suction blower flows into the hose from the exhaust port pipe, it is guided by the bent hose and changes its direction in the lateral direction. The loud noise from the blower, which is transmitted to the inside of the hose along with the exhaust air, reverberates to the irregularities on the inner surface of the hose, and is fully reflected in the bent hose of soft resin material to which the sound absorbing material is adhered. The sound will be absorbed, and the sound will be reduced to a low sound.

【実施例】【Example】

図1乃至図3は本考案の実施例を示し、多数のポット8aを有したトレイ8を 装填する育苗箱9を一方へ搬送することができる各搬送ローラ10aを有した搬 送装置10の上下にはケース11及び12をそれぞれ配備し、上方のケース11 内には、種子aを吸引する多数の吸引孔1を有して上方のモータ13により駆動 される回転式の播種ドラム2を軸架し、該播種ドラム2の前方には、開閉扉14 の下方に位置して底面15aがドラムの外周面まで傾斜するとともに仕切壁16 を有したホッパー15を装備し、前記播種ドラム2の下面にはスクレーパ17を 圧接するとともに、播種ドラム2の上方にはドラムの周面に向け排風しながら余 剰物を吹き飛ばすことができる吹出しノズル18を架設して従来形構造同様に構 成する。 1 to 3 show an embodiment of the present invention, in which a transfer device 10 having respective transfer rollers 10a capable of transferring a nursery box 9 loaded with a tray 8 having a large number of pots 8a to one side. Cases 11 and 12 are provided in the upper case 11, respectively, and a rotary seeding drum 2 driven by an upper motor 13 and having a large number of suction holes 1 for sucking the seeds a is mounted on the upper case 11. In front of the seeding drum 2, there is provided a hopper 15 located below the opening / closing door 14 and having a bottom surface 15a inclined to the outer peripheral surface of the drum and having a partition wall 16; The scraper 17 is pressed against the seeding drum 2, and a blow-out nozzle 18 is installed above the seeding drum 2 so as to blow away surplus substances while exhausting air toward the peripheral surface of the drum.

【0007】 また、下方の前記ケース12の内部には吸引式ブロワ3を内装して前記播種ド ラム2と同様に横方向となるブラワケース4を架設し、該ブロワケース4の吸気 側端面4aには前記播種ドラム2の一端側から延出する吸引管19を連通連設す るとともに、ブロワケース4の排気側端面4bには前記吹出しノズル18の一端 側より延出する排風管20を連通連設して構成するが、前記ブロワケース4の排 気側端面4bには排気口管5を挿着し、該排気口管5の外端部には内面に凹凸6 aを有した軟質樹脂材のホース6の一端部を嵌合し、該ホース6の中間部を横方 向に屈曲させてその先端口6bが図1に示すようにブロワケース4の先端側内周 面に接近して開口するよう平面視略L状に形設し、ホース6全体の外周には吸音 材7を接着して構成する。A suction type blower 3 is installed inside the lower case 12 and a lateral blower case 4 is erected in the same manner as the seeding drum 2, and an intake side end surface 4 a of the blower case 4 is provided. Is connected to a suction pipe 19 extending from one end side of the seeding drum 2, and an exhaust pipe 20 extending from one end side of the blowout nozzle 18 is connected to the exhaust side end surface 4b of the blower case 4. The blower case 4 is constructed by connecting the exhaust port pipe 5 to the exhaust side end face 4b of the blower case 4, and the soft resin having the inner surface with the unevenness 6a at the outer end part thereof. One end of the hose 6 made of a material is fitted, the middle part of the hose 6 is bent laterally, and its tip port 6b approaches the inner peripheral surface of the blower case 4 on the tip side as shown in FIG. It is formed in a generally L shape in plan view so as to open, and a sound absorbing material is provided on the outer circumference of the entire hose 6. 7 is bonded and configured.

【0008】 従って、吸引式ブロワ3に吸気される播種ドラム2により従来同様にトレイ8 に播種する状態で、吸引式ブロワ3からの排気が矢印イで示すように排気口管5 内に流れてホース6内に流れると、屈曲した該ホース6に案内されて横方向に向 きを変えるとともに凹凸6aにあたりながら勢いが弱まって周囲に悪影響を与え ないように先端口6bから流出することになり、その排気とともにホース6内に 伝わってくるブロワ3からの大きい音は、ホース6内面の凹凸6aに反響しなが ら、吸音材7を接着した軟質樹脂材の屈曲したホース6に充分に吸音されること になって、騒音とは感じられないような低音となるように低減されることになる 。Therefore, in the state where the tray 8 is seeded by the seeding drum 2 sucked by the suction type blower 3 as in the conventional case, the exhaust air from the suction type blower 3 flows into the exhaust port pipe 5 as shown by the arrow a. When it flows into the hose 6, it is guided by the bent hose 6 and changes its direction in the lateral direction, and while it hits the unevenness 6a, it loses its momentum and flows out from the tip opening 6b so as not to adversely affect the surroundings. The loud noise from the blower 3 transmitted to the inside of the hose 6 along with the exhaust air is not absorbed by the uneven hose 6a on the inner surface of the hose 6, but is sufficiently absorbed by the bent hose 6 of the soft resin material to which the sound absorbing material 7 is adhered. As a result, it will be reduced to a low tone that is not felt as noise.

【0009】 図4は他の例を示し、前記実施例とは同一符号で示すように略同様に構成する が、播種ドラム2の横側方には下方にまで延長する彎曲したガイド板21を架設 するとともに、その下端側にはシャッタ22を開閉自在にして装備し、その下方 となる搬送装置10の下方には、落下してくる種子aを受入れることができる受 樋23を架設したものであり、播種ドラム2内の吸引が止まると、シャッタ22 が閉じることになって、ドラムに吸着されている種子aがガイド板21内に落ち 込んで溜まることになり、下方のトレイ8及び育苗箱9を外してからシャッタ2 2を開くと、ガイド板21内の種子aを受樋23に落として、従来のように種子 aをこぼすことなく有効に収容できることになる。FIG. 4 shows another example, which has substantially the same structure as that of the above-mentioned embodiment as indicated by the same reference numeral, but a curved guide plate 21 extending downward to the lateral side of the seeding drum 2. In addition to being installed, a shutter 22 is provided at the lower end side so as to be openable and closable, and a gutter 23, which can receive the falling seed a, is installed below the transfer device 10 below the shutter 22. Yes, when the suction in the seeding drum 2 is stopped, the shutter 22 is closed, and the seeds a adsorbed on the drum are dropped into the guide plate 21 and accumulated, and the tray 8 and the nursery box below When 9 is removed and the shutter 22 is opened, the seed a in the guide plate 21 is dropped into the trough 23, and the seed a can be effectively stored without spilling as in the conventional case.

【考案の効果】[Effect of device]

このように本考案は、吸引式ブロワ3からの排気が排気口管5からホース6内 に流れると、屈曲した該ホース6に案内されて横方向に向きを変えるとともに凹 凸6aにあたりながら勢いを弱めて、周囲に悪影響を与えないよう流出させるこ とができることになり、その排気とともにホース6内に伝わってくるブロワ3か らの大きい音は、ホース内面の凹凸6aに反響しながら、吸音材7を接着した軟 質樹脂材の屈曲したホース6に充分に吸音されることになって、騒音とならない よう低音に低減させることができることになり、吸引式ブロワ3からの排風をよ わめたり騒音防止ができることになって、作業環境を良くすることができるとと もに簡単な構造にして好適に実施できる特長を有する。 Thus, according to the present invention, when the exhaust air from the suction blower 3 flows from the exhaust pipe 5 into the hose 6, it is guided by the bent hose 6 to change its direction in the lateral direction and hits the concave / convex 6a to exert momentum. It is possible to weaken it and let it flow out so as not to adversely affect the surroundings, and the loud sound from the blower 3 that is transmitted into the hose 6 along with its exhaust is reflected by the unevenness 6a on the inner surface of the hose while absorbing the sound absorbing material. Sound is fully absorbed by the bent hose 6 made of a soft resin material to which 7 is adhered, and it is possible to reduce the sound to a low level so as not to generate noise. Since it can prevent noise and noise, it can improve the working environment and has a feature that it can be suitably implemented with a simple structure.
