Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a concrete finishing machine.

[Conventional technology]

A typical method of installing and finishing concrete involves using separate equipment to place the concrete on a paved area and finishing the paved concrete surface to the desired grade. Paved areas include roads, parking lots, airport runways, and oversea areas.

Generally, concrete is discharged onto the paved area from a spreader, and is subjected to vertical vibrations (such as vertically moving members) well ahead of the concrete finishing machine. At that time, the deceased used a shovel to spread the concrete evenly over the JOL machine.

The concrete finishing machine follows behind, pushing the area to be paved with concrete in the opposite direction. The machine generally consists of a truss spanning the paved area and a finishing carriage mounted for movement along the length of the truss.

The finishing carriage consists of a rotary drilling drill to prepare the concrete to the appropriate grade and move excess concrete in the direction of machine movement, a rotary cylinder to harden and finish the concrete, and a float pan or drag to seal the concrete surface. It is equipped with a board. The finishing carriage moves in one direction until it reaches the side of the paved area and then reverses to the opposite side of the paved area.

Various apparatus for placing and finishing concrete are disclosed in the following patents:

Placing concrete generally relies on labor;
Sometimes it takes seven or eight men to evenly distribute the concrete.

In concrete placement, which occurs far into the concrete finishing process, it is extremely difficult to visually measure the appropriate amount to achieve the final grade. Sometimes it's too much or too little. If there is too much, the finishing machine or operator must move too much concrete across the paved area; if there is too little, the finishing machine must be refilled with concrete.

Furthermore, if there is too much distance or time between the concrete placement and the finishing process, problems extend to closing and sealing the concrete, as the concrete hardens before entering the finishing process. This problem becomes noticeable when the concrete finishing machine becomes stuck during finishing operations.

Conventional rotating cylinders of movable carriages are generally not completely satisfactory. The rotating cylinders move excess concrete to either side of the paved area or pour concrete over concrete that has already been finished by the rotating cylinders. In both cases, excess concrete must be forced to the front of the machine to fill any gaps that may exist.

Furthermore, many conventional structures cannot maintain a suitable grade when the truss axis is twisted relative to an axis perpendicular to the direction of movement of the finishing machine, making them unsuitable for placing or finishing large quantities of concrete. The present invention seeks to overcome these problems.

[Means for solving problems]

In summary, the present invention relates to a concrete finishing machine for placing and finishing concrete on paved areas with high efficiency and without requiring much human effort. The concrete finishing machine according to the invention has a frame provided across a paving area to be paved with concrete. The frame (i) defines an axis substantially perpendicular to the direction of movement of the frame and has orbitally engaged ends supporting the frame; each end includes a sliding connection connecting the end to the frame; , an adjustment device mounted at the end for maintaining the desired grade of the paved area when twisted about an axis perpendicular to the direction of movement of the frame.

The carriage is movably attached to the frame for movement along the length of the frame. The carriage has at least one rotating drilling drill unit and a finishing member.

The drilling awl unit includes a lead portion and a drag portion on an axis substantially along the direction of movement of the frame body. A concrete vibrator is provided on the side of the reed. The lead portion has a spiral blade that pushes excess concrete in the direction of movement of the frame. The drag section has a continuous band on the outer end of a helical blade that contacts the concrete surface to achieve the desired grade.

The drag section pushes excess concrete and assists in finishing the concrete. In this way, the excavator m unit solves the problem of the concrete being pushed to the side of the paved area due to the rotation of the cylinder.

The finishing member has a horizontal surface that intersects the concrete surface to finish it to the desired grade. The finishing member is located adjacent to the dragging part of the drilling drill unit while maintaining the following relationship with respect to the direction of movement of the frame. If two parallel drilling awl units are used, the finishing member has means for moving it between the first and second positions. The position 1lE1 is arranged along the axis defined by the first drilling awl unit and the second position is arranged along the axis defined by the second drilling awl unit.

The concrete conveying means is mounted on the frame and extends substantially along the frame axis. The conveying means has a side discharge station which is mounted on the conveyor and discharges concrete from the conveyor into a paved area along the length of the conveyor at a constant distance from the trenching unit G-P section. Orient to. The side discharge station includes a spade for directing the concrete, a discharge chute for directing the concrete into the paving area, means for moving the station along the length of the conveyor, and a zolat form on which an operator of the concrete finishing machine rests. .

The operator is located centrally and controls all processes of this concrete finishing machine. The operator may also direct the concrete onto the paved area by moving a foot placed in a stirrup attached to the dispensing portion of the delivery chute of the conveying vehicle.

It is thus an object of the present invention to provide a machine for placing and finishing concrete in large quantities and with reduced labor.

Another object of the present invention is to provide a concrete finishing machine that maintains a desired grade even when the frame axis is twisted about an axis perpendicular to the direction of frame movement.

Yet another object of the present invention is to provide a concrete finishing machine that reduces the time and distance between placing concrete on the paved area to be paved and finishing.

Another object of the present invention is to provide a concrete finishing machine that allows a single operator to centrally control the process of placing concrete on a paving area to be paved and the finishing process.

Still another object of the present invention is to provide a concrete finishing machine that applies vibration to a section of concrete placed on a paved area to solidify the concrete.

Still another object of the present invention is to provide a concrete finishing machine that pushes excess concrete in the direction of movement of the frame to fill existing gaps.

Yet another object of the invention is to provide a concrete finishing machine having a simple, efficient and reliable construction.
