Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a concrete finishing machine. BACKGROUND OF THE INVENTION A typical method of setting and finishing concrete involves placing the concrete on a paved area using separate concrete setting and finishing equipment to finish the paved concrete surface to the desired height. Paved areas include roads, parking lots, airport runways, and bridges. Generally, concrete is discharged onto the paving area from a spreader and is subjected to vertical vibrations by means of a vertically moving member or the like well ahead of the concrete finishing machine.
At this time, several people use shovels to spread the concrete evenly over the concrete finishing machine. The concrete finisher follows and extends laterally across the area to be paved with concrete. Concrete finishing machines generally consist of a truss spanning the paving area and a finishing carriage mounted for movement along the length of the truss. The finishing carriage has a rotating auger unit to raise the concrete surface to an appropriate height and move excess concrete in the direction of progress of the finishing machine, a rotating cylinder to harden and finish the concrete, and a float pan to seal the concrete surface. Or a drag plate. 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 apparatuses for placing and finishing concrete are disclosed in the following patents.

[Table] Vibrating Ruler with Placement [Problems to be Solved by the Invention] The apparatus described and disclosed in the above-mentioned patents exhibits a number of deficiencies in the practical aspects of placing or finishing concrete. Placing concrete is generally labor dependent, sometimes requiring seven to 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 concrete surface height. Sometimes it's too much or too little. If there is too much, the finisher or operator must move a significant amount of concrete across the paving area; if there is too little, the finisher must be refilled with concrete. Additionally, if there is too much distance or time between concrete placement and finishing, 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 suddenly stops working during finishing work. 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 either case, excess concrete must be forced to the front of the finishing machine to fill any gaps that may exist. Furthermore, in many conventional structures, if the truss shaft is twisted relative to the axis perpendicular to the direction of movement of the finishing machine, it becomes impossible to maintain an appropriate concrete surface height, making it unsuitable for placing and finishing large amounts of concrete. Become. The present invention seeks to overcome these problems. [Means for Solving the 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 labor. The concrete finishing machine according to the invention has a frame provided across a paving area to be paved with concrete. The frame defines an axis substantially perpendicular to the direction of movement of the frame and has a track-engaging end supporting the frame. Each track-engaging end has a sliding connection connecting the track-engaging end to the frame to maintain the desired height of the paved area even when the frame is twisted about an axis perpendicular to its direction of movement. and an adjustment device attached to the track engagement end for adjusting the track engagement end. The carriage is movably attached to the frame so as to move along the length of the frame. The carriage has at least one rotating auger unit and a finishing member. The auger unit includes a leading portion and a trailing portion on an axis substantially along the direction of frame movement. The concrete vibrator is provided on the side of the leading part. The leading portion has a spiral blade for pushing excess concrete in the direction of movement of the frame. The trailing portion has a continuous band on the outer end of the helical blade that contacts the concrete surface and brings the concrete surface to the desired height. The trailing section pushes excess concrete and assists in finishing the concrete. In this way, the auger unit solves the problem of concrete being pushed to the side of the paved area by the rotation of the cylinder. The finishing member has a horizontal surface that intersects the concrete surface to finish the concrete surface to a desired height. The finishing member is located adjacent to the trailing portion of the auger unit, maintaining the following relationship with respect to the direction of movement of the frame. If two parallel auger units are used, the finished member will be
and means for moving it between a first and a second position. The first position is where the finishing member is aligned with the axis of the first auger unit, and the second position is where the finishing member is aligned with the axis of the second auger unit. The concrete conveying means is provided on the frame and extends substantially along the axis of the frame. The conveying means has a side discharge station mounted on the conveyor for discharging concrete from the conveyor onto a paved area along the length of the conveyor at a fixed distance from the leading section of the auger unit. give direction. The side discharge station includes a plate for directing the concrete, a discharge chute for directing the concrete onto the paving area, means for moving the side discharge station along the length of the conveyor, and a platform 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 also
Concrete can be directed onto the paved area by moving a foot resting on a stirrup attached to a resilient member of the discharge chute of the conveying means. 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 concrete surface height even when the frame 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 paving area to be paved and finishing the concrete. 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 vibrations to solidify concrete at the point where it is placed on a paved area. 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. [Example] In FIGS. 1 to 3, the concrete finishing machine 22 includes a cross member 27, a truss 28, and a top chord member 2.

are spaced parallel and bolted to main supports 69, 71 substantially along the frame axis 25. Truss 28 and top chord 29 are bolted together to angle 26. The top chord member 29 is arranged along a line along the frame axis 25. Top chord member 30 for adjustment having an adjustment screw 31 for adjusting the length
is placed within the line of the top chord 29 which adjusts the horizontal shape of the frame. As depicted in FIG. 3, the cross section of the frame 24 is parallel to the direction of movement of the frame and has a substantially triangular shape. The main supports 69, 71 are slidably secured to the track engagement ends 36, 38 that support the frame 24. Track engaging ends 36, 38 each have a roller 44 adapted to move on tracks 40, 42 for moving the frame. Cross member 27 and truss 28 form one part of frame 24 . The sections terminate in cross members 27 and top chords 29 connect adjacent sections. Concrete finishing machine 22 is designed to use one, two or more sections. By using different numbers of sections, concrete finisher 22 can accommodate any width of paved area 20. As shown in FIGS. 1 and 2, the frame portions extend beyond the track engagement ends 36, 38 so that the standard size portions extend beyond the track engagement edges adjacent to the sides of the paved area 20. It does not interfere with the position of the ends 36, 38. The carriage 46 connects the first and second auger units 4
8 and 50 are mounted so as to rotate in parallel at intervals. 7 and 8, each auger unit has a leading portion 104 and a trailing portion 106 welded onto an axis 116 along the direction of movement of the frame. The leading portion 104 has a spiral blade 108 made of steel for pushing excess concrete in the direction of movement of the frame. The trailing portion 106 is a spiral blade 110 made of steel and has a continuous band 114 welded to its outer edge 112. The trailing section 106 serves to push excess concrete towards the leading section 104 and helps the strip 114 contact the concrete to finish the concrete to the desired height. As shown in FIG. 7, the reading section 10
The four helical blades 108 have a desired height 111 and outer edges 109 spaced at regular intervals. This constant spacing is approximately 3/8 inch, leaving excess concrete to be handled by the trailing section 106 of the auger unit, which then spreads the excess concrete to fill the gap. . Spiral blade 108,1 of first auger unit 48

The finishing member 52 is located adjacent to the trailing portion 106 of the auger units 48, 50, and has the following relationship with respect to the direction of movement of the frame. The bottom plate 120 of the finishing member 52 alternates between first and second positions. The bottom plate 120 is connected to the auger unit 4 when the first auger unit 48 reaches the end of the paved area 20 adjacent the track engagement end 36.
A first position aligned with the axis of 8 has been reached. The bottom plate 120 has reached a second position in which it is aligned with the axis of the auger unit 50 when the second auger unit reaches the end of the paved area 20 adjacent the track engagement end 38. The bottom plate 120 thus moves along the length of the frame at a faster speed than the carriage 46 and is located at the edge of the paved area 20 whenever the carriage 46 reaches either side of the paved area 20. It's becoming like that. The conveyor 54 includes a track engaging end 36 of the frame 24,
