Description

  The present invention relates to a stirrer for kneading a cement kneading material, and more particularly to the structure of a lid in the stirrer.

  The stirrer for cement kneading material of Patent Document 1 has a lid that covers the upper opening of the bottomed stirring drum, and the lid is a grid of metal wires, and a large number of openings between each grid-assembled metal wire. It has a structure in which a window is formed.

  The lid of the agitator is formed by crossing a radial large-diameter wire and an annular large-diameter wire, forming a hook portion at the outer end of the radial large-diameter wire, and hooking the hook portion on the upper end of the stirring drum. It is configured to keep the body closed.

  A plurality of large-diameter open windows are defined by the radial large-diameter wire and the annular large-diameter wire arranged so as to intersect with the radial large-diameter wire, and the cement kneading material can be input through the large-diameter open window.

  Further, the lid body is not connected to the stirring drum, but can be detached from the drum and removed.

JP-A 63-175632

  In the cement kneading material agitation device, an operator must lift and close the agitation drum by lifting a heavy weight lid. At this time, hook the hook part to the upper end of the agitation drum visually. Opening and closing work must be complicated.

  In addition, the hook part may be deformed by an external force and cannot be latched, or there may be play in the latch part (lid).

  In addition, since it is multi-point support by the hook part, it has a problem inferior in load resistance.

  In the present invention, a drum pad made of a metal wire arranged in a ring shape is formed on the outermost peripheral portion of a lid formed by assembling metal wire rods, or the outermost periphery of a lid formed by laminating metal wire rods A drum pad is formed with a metal frame plate arranged in a ring in the section, and the annular metal wire or ring metal frame plate forming the annular drum pad is closed to the annular lid pad at the upper end of the stirring drum. The load resistance against the load on the lid and the external load is improved by an annular drum pad made of the annular metal wire or the annular metal frame plate.

  In addition, the hook-hanging structure is eliminated and problems such as deformation of the hook, backlash, and hindrance to the hook are solved.

  Furthermore, an annular metal wire or an annular metal frame plate forming the annular drum pad is attached to the upper end of the stirring drum via a hinge so as to be able to be opened in a single direction so that the lid can be easily opened and closed.

  Furthermore, a switch is provided to stop the rotation of the stirring blade in the stirring drum when the lid is opened at the hinge portion, and to rotate the stirring blade when the lid is closed. While ensuring the safety, the rotation of the stirring blade is stopped in synchronization with the opening of the lid, and the safety at the time of non-kneading (when opening the drum upper opening) is ensured. This is also a measure to save power.

  The lid body has a structure in which a structural bone made of a large-diameter metal wire and an inter-bone made of a thin metal wire that subdivides an open window between the structural bones arranged between the structural bones. This prevents the insertion of fingers through the body, the intrusion of foreign matter, etc., and further improves the safety.

  According to the present invention, a lid structure in which an annular metal wire or an annular metal frame plate is provided on the outermost peripheral portion of the lid, and the annular metal wire rod or the annular metal frame plate is annularly attached to the lid upper end of the drum. The load-carrying capacity of the lid body can be significantly improved by the configuration of loading and closing the lid, and can be properly closed by the annular metal wire rod or the annular metal frame plate, so that the problems caused by the conventional hooking can be effectively solved. .

  Also, the hinge can be easily opened and closed by the hinge, and the switch provided on the hinge is automatically turned off in synchronization with the opening of the lid to stop the stirring blade to ensure safety and save power. be able to. As a result, it is possible to eliminate the complexity of having to repeatedly turn the switch on and off during the work.
