The material distribution machine with trowel function includes a hopper 1, a bin door 3, a walking assembly 6, a material distribution disc 7 and a trowel assembly 5. The lower end of the hopper 1 has a discharge port; the bin door 3 is arranged at the discharge port, and the discharge port is closed or opened by means of a bin door driving element 2; the walking assembly 6 is used to drive the hopper 1 to move back and forth along the concrete prefabricated part production line; the material distribution disc 7 is installed below the hopper 1, and is driven to rotate by a material distribution motor 4, and is used to evenly distribute the material falling into the material distribution disc into the mold cavity, and the material distribution motor 4 is connected to the walking assembly 6; the trowel assembly 5 is installed on one side of the walking assembly 6, and is used to trowel the surface of the concrete product after the material distribution is completed.

[0042] Compared with the prior art, the material distributing machine with a troweling function provided by the present invention is provided with a troweling component 5. In the material distributing process, the troweling component 5 moves back and forth along the production line with the walking component 6. When distributing, the bin door 3 is opened, and the material falls into the mold from the hopper 1. The material is first evenly distributed by the distributing plate 7, and then the top of the concrete product is smoothed by the troweling component 5, so that the surface of the product is smooth. The distributing and troweling are carried out simultaneously, which improves the quality of the product, shortens the production cycle, and improves the production efficiency. Among them, the walking component 6 is installed on the concrete prefabricated part production line, driving the material distributing machine to move back and forth above the mold, and the distributing plate 7 rotates forward and reversely under the action of the distributing motor 4. As the walking component 6 moves forward, the material is evenly distributed into the mold cavity, and the excess material is scraped away by the distributing plate 7.

[0043] Please also read Figure 1 and Figure 4 As a specific embodiment of the concrete placing machine with trowel function provided by the present invention, the trowel assembly 5 includes a trowel board 51 and a trowel driving element 55. The trowel board 51 has a smooth lower surface and is used to trowel the surface of the concrete product after the trowel is placed. One end of the trowel driving element 55 is connected to the walking assembly 6, and the other end is hinged to the trowel board 51, which is used to control the lifting and lowering of the trowel board 51 to achieve the trowel effect. Among them, the trowel driving element 55 can be a cylinder, a hydraulic cylinder and an electric push rod, and the lifting and lowering of the trowel board 51 is driven by the extension and retraction of the cylinder rod. In this embodiment, the material distributing machine distributes the material to the mold twice, that is, the material distributing machine distributes the material once when the traveling assembly 6 advances, and after reaching the other end of the mold, the traveling assembly 6 returns to distribute the material to the mold twice. The trowel assembly 5 is installed at the front end of the material distributing machine in the forward direction. When in use, during the first distribution, the trowel board 51 is lifted up and leaves the mold under the action of the trowel driving element 55. When the material distributing machine returns, the trowel board 51 is put down and tangent to the mold to trowel the surface of the product after distribution. At the same time, due to the passage of the trowel board 51, the surface of the product after distribution is smooth. In this way, the production quality of the product can be improved.

[0053] The present invention also provides a method for spreading and smoothing materials, and the process is as follows: when the walking component 6 drives the hopper 1, the feeding plate 7 and the smoothing component 5 to move forward, the smoothing component 5 rises, and when the hopper 1 moves to the top of the mold, the door 3 opens, and the material is spread once. At this time, the excess material is scraped off by the feeding plate 7 itself, and the material protruding from the mold is scraped into the unfilled cavity; when the walking component 6 moves to the other end of the mold, the walking motor 61 reverses, the walking component 6 drives the hopper 1 to return, the smoothing component 5 descends to a position close to the mold, and the door 3 of the hopper 1 continues to open, and the secondary spreading is carried out. At this time, the smoothing plate 51 after the spreading smoothes the surface of the product just after the spreading, and smoothing can be achieved while spreading. Through the secondary spreading, the material is evenly distributed and compacted, the density of the prefabricated parts is improved, the intrinsic quality of the product is improved, and the surface quality of the product is improved by smoothing.
