Description

Technical Field

[0001] The invention relates to the technical field of trowel machines, and more specifically to an automatic trowel machine for producing concrete pipe segments. Background Art

[0002] The working principle of the automatic trowel machine relies on a powerful power system to drive the trowel disc to rotate. The weight of the trowel machine is evenly distributed, which helps to apply stable pressure to the concrete surface. The specially designed trowel disc can adapt to concrete areas of different flatness, effectively remove bubbles and pores on the concrete surface, and enhance the density of the concrete. At the same time, the advanced transmission system ensures the stability and accuracy of the trowel disc rotation, and the speed regulation function of the equipment can adjust the trowel speed according to actual needs.

[0003] There are some shortcomings in the use of existing automatic trowel machines, as follows:

[0004] The existing automatic trowel machine rotates the trowel plate on the outside of the concrete segment during use, so as to smooth the surface of the concrete segment. When the trowel machine is performing the smoothing work, the trowel plate will absorb the concrete as the smoothing work proceeds. If the next smoothing work is not performed for a long time, the concrete on the trowel plate will solidify, making it inconvenient to perform the next smoothing work. In addition, since the trowel plate rotates on the outside and needs to spend a lot of time to rotate to smooth the outside of the concrete segment, it is not easy to ensure production efficiency.

[0014] Technical effects and advantages of the present invention:

[0015] 1. When producing concrete segments, the present invention adjusts the arc length of the mold according to the arc length of the segments to be produced, and then drives the second gear to rotate through the operation of the second servo motor, and then drives the inner transmission gear ring to rotate through the mutual engagement between the second gear and the inner transmission gear ring, and under the positioning of the segment positioning assembly by the first positioning assembly and the second positioning assembly, the segment positioning tube rotates, and then drives the first baffle plate outside the segment positioning tube to rotate, and then adjusts the angle between the first baffle plate and the second baffle plate, so that the equipment can adjust the angle between the first baffle plate and the second baffle plate according to the production requirements of the concrete segments, so that the equipment can produce concrete segments with different arc lengths, which is convenient for the use of the equipment.

[0016] 2. The present invention lays concrete on the outer side of the segment positioning tube, and then when the concrete segment is smoothed, the first servo motor drives the first gear to rotate, and then the teeth on the outer side of the first gear and the teeth on the outer side of the outer transmission gear ring engage with each other, driving the outer transmission gear ring to rotate, and then under the positioning of the second positioning bearing, the positioning ring and the outer transmission gear ring rotate relative to the second positioning bearing, and then drives the smoothing plate assembly to rotate synchronously, and then during the rotation of the smoothing plate assembly, the push ball contacts the corrugated push ring, and when passing through the protrusion of the corrugated push ring, the push ball, the first L-shaped positioning rod and the first positioning plate are turned back and forth. The convex sliding block slides inside the convex sliding groove, and the convex sliding block moves toward the front relative to the convex sliding groove, so that the telescopic rod is compressed. Then, when the pushing ball moves from the convex portion of the corrugated pushing ring to the concave portion, the telescopic rod causes the trowel plate body to move toward the back, so that the trowel plate body will vibrate toward the front and back during the rotation, so that the surface of the concrete segment can be smoothed, and the shaking of the trowel plate body can expel the bubbles in the concrete segment, so that the concrete segment can be effectively smoothed.

[0017] 3. In the present invention, when the main body of the trowel plate rotates to the bottom of the outer side of the segment positioning tube and passes through the second telescopic inclined plate, the second telescopic inclined plate is pushed by the main body of the trowel plate to move closer to the first telescopic inclined plate and at the same time the first telescopic inclined plate is moved closer to the positioning arc plate until the scraping inclined surface fits the side of the main body of the trowel plate close to the segment positioning tube, and then the concrete adsorbed on the side of the main body of the trowel plate close to the segment positioning assembly can be scraped off by the scraping inclined surface. When the trowel plate assembly leaves the scraping inclined surface, the concrete scraped off by the scraping inclined surface will bounce onto the positioning bottom plate under the action of the rebound of the first telescopic inclined plate and the scraping inclined surface, which can effectively remove the concrete adsorbed on the side of the main body of the trowel plate close to the segment positioning assembly, thereby avoiding the situation where the concrete on the main body of the trowel plate solidifies due to the long-term non-performance of the next troweling work.
