Description

        The present invention changes the angle of the box where the bucket of a construction machine, such as a shovel car, crawls, when dropping the construction material excluding cobblestones such as crushed stone, sand, gravel, earth and sand, and residual soil after dropping it with a shovel car In addition, the construction material can be dropped to the target position by simply opening the drop opening provided on the bottom wall of the bucket body in a predetermined place without swinging, and the bucket structure of different sizes can be attached and detached. The present invention relates to a bucket structure that can be easily and quickly attached and detached through a simple connector.

        Conventionally, when transporting crushed stones, sand, gravel, earth and sand (hereinafter simply referred to as construction materials) of construction materials using buckets of construction machines such as excavators and dropping them into place, It was a process of transporting the stored bucket to a predetermined position, bending it to an angle at which the construction material in the bucket falls, and then repeating the operation of dropping the construction material by swinging or vibrating the bucket. As a result, work efficiency was poor, time consuming, noisy, and increased costs.

        In addition, when exchanging buckets with different storage capacities on construction machines, it is necessary to change all the connection points related to the arm and the connection of the hydraulic system, angle change hydraulic cylinder, etc. However, skill was indispensable.

        Therefore, there has been known a proposal in which an attachment is provided between an arm and a bucket of a construction machine. (For example, see Patent Documents 1 and 2)

  JP 7-279192 A   JP-A-8-4043

        However, when transporting and dropping construction materials with construction machines at the construction site, there are many types of working materials and types, and there are many working environments where work time and noise are regulated. Further, in Patent Documents 1 and 2, attachments are complicated and expensive, and there is a possibility that troubles that often cause troubles occur under severe conditions such as residential areas.

        In order to solve such problems, the present invention can reliably and directly drop construction materials in a moved place without changing the angle of the bucket body for housing construction materials of construction machines such as excavators. It is an object of the present invention to provide a bucket structure for a construction machine that is provided with a simple connecting tool and facilitates replacement of a bucket body having a different size.

        In order to solve such a problem, the present invention is a method for dropping construction materials stored in a scoop box composed of a bottom wall, a backmost wall, a back wall, and a side wall of a bucket body for construction materials in an excavator car or the like. A rectangular, square, circular, etc. drop opening is drilled in the innermost wall, and a lid opening / closing mechanism that closes or opens the drop opening is attached to the back of the back wall of the scooping box and accommodated in the scooping box It is a bucket structure in which the construction material is opened directly above the specified position, the construction material is surely dropped to a predetermined position, and the upper opening of the scooping box portion of the bucket body is covered with an enclosure. .

        In addition, the enclosure includes a triangular left and right rising side plate with the lower end fixed to the upper edge of the outer peripheral edge reinforcing plate fixed to the side wall end of the bucket body, and the left and right with the lower edge fixed to the upper edge. An inclined plate, a left and right upper and lower triangular plate fixed between the upper edge of the intermediate inclined plate and fixed in parallel to the bottom wall, a central connecting plate fixed to the edge, and an upper end of the back wall It is a bucket structure having a configuration in which the lower end edges of the left and right upper surface plates and the central connection plate are fixed to and integrated with the upper end edge of the top wall which is also a reinforcing material in which the lower end edge portion is fixed in parallel with the bottom wall.

        In addition, the connecting tool is a clogged reverse tooth shape, and its mounting part is attached to the surface of the central connecting plate, and the main arm connected to the boom, the tip of the link arm for changing the angle, and bolts, nuts, etc. It is a bucket structure that is configured as a separation type that can be attached and detached through a tool, covers the upper surface of the frontage, and prevents the construction material stored during transportation from falling outside. In addition, a bucket structure provided with a fastening hole for connection corresponding to the pitch of various connecting parts in order to connect to the connecting part at the tip of various arms in the central part connecting plate and the connecting tool detachably attached to the connecting plate Is the body.

        Further, the lid opening / closing mechanism is a position where the bucket main body does not interfere with the work of scooping up the construction material, i.e., the back surface in the vicinity of the innermost wall, and a support base and a drive source that pivotally supports the lid opening / closing mechanism at a position located on the back wall. A bucket structure having a box-shaped lid reinforcing portion having a support portion serving as a shaft fulcrum of the cylinder, and a lid having a size that closes the dropping opening of the scooping box portion.

        The scooping box, the enclosure, and the reinforcing plate are mainly fixed by welding, but can also be fixed by a fastener.

        The enclosure can be configured at an angle that does not cause the fallen construction material to fall, and can be held at many angles, and is the maximum size that covers the construction material so that it does not fall from the bucket body during transportation of the construction material. For example, a single steel plate such as an inclined side wall may be bent to form a curved surface.

        Also, the drop opening can be formed up to the vicinity of the side wall according to the size of the scooping box. However, the lid opening / closing mechanism needs to have the same size.

        The bucket structure according to the present invention can transport the housed construction material to a predetermined position without falling outside the bucket body, and the construction material is drilled in the innermost wall of the bucket structure just above the designated position. Since the construction material in the bucket body can be dropped simply by opening the installed drop opening with a lid opening / closing mechanism, there is a feature that the carrying work and the dropping work can be performed efficiently.

        In addition, the drop opening is drilled in the deepest wall of the scooping box, so that the construction material transported when dropping the construction material is not scattered around the area, and the cost of man-hours such as post-processing workers can be eliminated There is.

        Furthermore, the upper portion of the bucket structure is covered with an enclosure so that the amount of construction material accommodated in the scooping box can be greatly increased, and the cost of construction material transportation efficiency and the like can be greatly reduced.

        The couplers are provided in accordance with the sizes of various bucket arms and link joints at different sizes, and in a short time and easily using fasteners such as bolts and nuts provided on the central coupling plate. It can be exchanged without requiring skill, and can be exchanged for buckets with different storage capacities in a very short time.
