BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 It is a schematic structural diagram of a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0016] like Figure 1 As shown, this embodiment discloses a screw conveying and mixing machine for use with a shotcrete machine, including a feed barrel, a feed hopper 8, a slurry discharge port 16, a water supply pipeline 19 and a quantitative water feeder 7; in this embodiment, the feed barrel is arranged obliquely, and the inside of the feed barrel is divided into a material chamber 17 and a drainage chamber 18 by a baffle 6, the feed hopper is connected to the lower end of the material chamber, the slurry discharge port is connected to the high end of the material chamber, and the side wall of the feed barrel is provided with a drainage port 5 connected to the drainage chamber.

[0017] A rotating shaft is rotatably installed in the feed barrel, and both ends of the feed barrel are respectively sealed with a front end bearing seat 3 and a rear end bearing seat 4 rotatably assembled with the rotating shaft. Pushing screws and concrete mixing blades are alternately installed on the rotating shaft. In this embodiment, a first-level pushing screw 9, a first-level concrete mixing blade 10, a second-level pushing screw 11, a second-level concrete mixing blade 12, a third-level pushing screw 13, a third-level concrete mixing blade 14 and a fourth-level pushing screw 15 are sequentially installed on the rotating shaft along the pushing direction.

[0018] The shaft is driven to rotate by a shaft driving mechanism, and the shaft driving mechanism includes a motor 1 and a coupling 2 in transmission connection, and the coupling is transmission-connected to one end of the shaft.

[0019] The water outlet end of the water supply pipeline is located above the feed hopper, and a quantitative water feeder is installed on the water supply pipeline.

[0020] During operation, river sand, cement, water and other concrete raw materials are added into the material chamber through the feed hopper according to the proportion. The motor drives the shaft to rotate. The concrete raw materials are pushed and stirred alternately in multiple stages. After becoming qualified concrete slurry, they are transported to the shotcrete machine through the slurry discharge port. During the slurry transportation and stirring process, excess water can be discharged through the drain port.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
