【発明の詳細な説明】
〔産業上の利用分野〕
本発明はコンクリート等の圧送用ポンプに関するもので
あるが、コンクリートのみならず、米。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pump for pumping concrete, etc., but it can be used not only for concrete but also for rice.
麦、大豆等の穀物圧送にも適用しうる。It can also be applied to the pressure feeding of grains such as wheat and soybeans.
従来のコンクリート圧送用のポンプは
■圧縮空気式
■チューブ式
■プランジャー式
等があるが、何れも構造が複雑で間歇送りであり、効率
が悪かった。Conventional concrete pumps include compressed air type, tube type, and plunger type, but all of them have complicated structures, feed intermittently, and are inefficient.
一方、螺旋状に延びる回転翼よりなるスクリューポンプ
は連続的に効率よ（流体を輸送できるものである。On the other hand, a screw pump consisting of spirally extending rotor blades can transport fluid continuously and efficiently.
しかしこのスクリューポンプはその翼先端とポンプ外筒
の内周面間に石、砂利等の骨材を噛み込む（挟み込む）
欠点があるのでコンクリート圧送用のポンプには利用で
きなかった。However, with this screw pump, aggregates such as stones and gravel are caught between the blade tip and the inner circumferential surface of the pump outer cylinder.
Due to its drawbacks, it could not be used as a concrete pump.
本発明はかかるスクリューポンプをコンクリート等の圧
送に適用しうるようにしたものである。The present invention allows such a screw pump to be applied to the pumping of concrete and the like.
本発明はポンプ外筒１内にスクリュー２を回動ずべく設

のベアリング３の内筒４は上記スクリュー２の外＠緑に
固定部５により固定してなるコンクリート等の圧送用ポ
ンプである。In the present invention, a screw 2 is provided inside the pump outer cylinder 1 so as not to rotate, and a bearing 3 is provided at the inlet of the outer cylinder. This is a fixed pump for pressure-feeding concrete, etc.
スクリュー２の回転によりベアリング３の内筒４もその
スクリュー２０回転翼と一緒に回転するので、スクリュ
ー２とポンプ外筒１間にはコンクリート骨材等の異物を
噛み込むことがない。As the screw 2 rotates, the inner cylinder 4 of the bearing 3 also rotates together with the rotary blades of the screw 20, so that no foreign matter such as concrete aggregate gets caught between the screw 2 and the pump outer cylinder 1.
図中、ベアリング３はボールベアリングであるが、他の

はコンクリート投入口である。In the figure, the bearing 3 is a ball bearing, but other bearings may be used. 5 is a fixed part by welding. 6 is the shaft of the screw 2, 7 is its driving motor, 9
is the concrete inlet.

けるとよい、また、軸６を駆動する代わりに内筒４を駆
動するようにしてもよい。The rotation of the pump outer cylinder 1 and the screw 2 can be further improved by providing an elastic seal member 8 made of rubber or the like that slides against the inner circumferential surface of the pump outer cylinder 1 on the edge of the rotor blade of the screw 2, that is, a spirally extending blade. This can prevent aggregates from getting caught between the wings. Note that a similar bearing 10 may be provided at the outlet of the pump outer cylinder 1, and the inner cylinder 4 may be driven instead of driving the shaft 6.

クリートを圧送でき、スクリューによりコンクリートを
連続的に効率よく圧送することができるものである。[Effects of the Invention] As described above, according to the present invention, it is possible to prevent aggregate from being caught between the pump outer cylinder 1 and the rotor blades of the screw 2, so concrete can be pumped, and the concrete can be continuously and efficiently transported by the screw. It can be easily pumped.
