[0023] Example 1:
[0024] Example 1 of the present application provides a cement stabilized gravel material distribution and paving machine, such as Figure 1 As shown, it includes: a material receiving system 1, a transporting system 2, a material distribution system 3 and a surface leveling system 4;
[0025] Among them, the material receiving system 1 is arranged above the transporting system 2, and the material receiving system 1 has a unloading valve 13 with the unloading direction toward the transporting system 2; a distribution system 3 is provided at the bottom of the transporting system 2, and the distribution system 3 is used to distribute the crushed stone unloaded by the material receiving system 1 when the transporting system 2 is moving; the surface leveling system 4 is connected to the tail of the transporting system 2.
[0026] like Figure 2 and Figure 3 As shown, the material receiving system 1 includes a material box 11, a supporting jack 12 and a discharge valve 13; the material box 11 is connected to the carrying system 2 through the supporting jack 12; the lower part of the material box 11 is tilted inward and connected to the discharge valve 13; the discharge valve 13 is semi-arc-shaped and is used to control the discharge section width B and the discharge height H.
[0027] like Figure 4 and Figure 5 As shown, the transport system 2 is a three-row wheel transport vehicle, including front wheels 21, crushing wheels 22, connecting axles 23 and vehicle plates 24; the two wheels in the same row are connected by connecting axles 23; the vehicle plates 24 are connected to the material box 11 through the supporting jacks 12.
[0028] like Figure 6As shown, the distribution system 3 is composed of conical distribution plates arranged in three rows, including: a first row of distribution plates 31, a second row of distribution plates 32, and a third row of distribution plates 33; wherein, the distribution plate opening angles of the first row of distribution plates 31, the second row of distribution plates 32, and the third row of distribution plates 33 and the heights of the bottoms of the distribution plates from the ground decrease successively; and a reinforcing support 34 is provided behind any distribution plate.
[0029] The surface leveling system 4 includes a counterweight 41 and a screed plate 42; the counterweight 41 is placed on the screed plate 42; the front end of the screed plate 42 is connected to the carrying system 2; the weight of the counterweight 41 is adjusted according to the compressibility of the paved material; the front end of the screed plate 42 is higher than the rear end, the rear end height of the screed plate 42 is the paving thickness h, and the width of the screed plate 42 is the preset paving width b.
[0030] Example 2:
[0031] Based on Example 1, Example 2 of the present application provides a method for using a cement-stabilized gravel distribution and paving machine, including:
[0032] Step 1: The cement-stabilized gravel prepared by the mixing tower is carried by the material box 11. The material-carrying system 1 is stabilized by adjusting the number of supporting jacks 12. The transport system 2 transports the equipment to the area to be paved and prepares for laying the material.
[0033] Step 2: The transport system 2 is a three-wheeled transport vehicle that can be self-propelled or towed by other transport machinery. The transport system 2 moves along a predetermined route. During the process, the unloading valve 13 opens and unloading begins. The unloading section width B and the unloading height H can be controlled by the opening and closing angle and the travel speed of the transport system 2 to achieve quantitative unloading.
[0034] Step 3: The distribution plate is conical and is located behind the distribution port and in front of the rolling wheel 22. It is equipped with a reinforced support 34 to increase the rigidity (anti-deformation ability) of the distribution plate. When the distribution plate contacts the cement-stabilized gravel, it pushes the contact part to the sides, thereby reducing the height of the pile and increasing the width, thus achieving distribution. Multiple distribution can reduce the resistance of a single distribution and make the distribution more uniform.
[0035] Step 4: The weight of the counterweight 41 can be adjusted according to the compressibility of the paving material. The front end of the screed plate 42 is higher than the rear end. The rear end height is the paving thickness h, and the width of the screed plate is the preset paving width b.
[0036] At this point, the single-pass spreading is completed and strip-shaped reciprocating paving can be continued. This solution saves materials and has high construction efficiency.
[0037] Specifically, the method provided in this embodiment is the method corresponding to the device provided in Example 1. Therefore, the parts in this embodiment that are the same or similar to those in Example 1 can be referenced to each other and will not be repeated in this application.
